Zip archives can be created, or you can read from existing zip files. Once created, they can be written to files, streams, or strings. Members can be added, removed, extracted, replaced, rearranged, and enumerated. They can also be renamed or have their dates, comments, or other attributes queried or modified. Their data can be compressed or uncompressed as needed. Members can be created from members in existing Zip files, or from existing directories, files, or strings. This module uses the L library to read and write the compressed streams inside the files. One can use L to read the zip file archive members as if they were files. =head2 File Naming Regardless of what your local file system uses for file naming, names in a Zip file are in Unix format (I slashes (/) separating directory names, etc.). C tries to be consistent with file naming conventions, and will translate back and forth between native and Zip file names. However, it can't guess which format names are in. So two rules control what kind of file name you must pass various routines: =over 4 =item Names of files are in local format. C and C are used for various file operations. When you're referring to a file on your system, use its file naming conventions. =item Names of archive members are in Unix format. This applies to every method that refers to an archive member, or provides a name for new archive members. The C methods that can take one or two names will convert from local to zip names if you call them with a single name. =back =head2 Archive::Zip Object Model =head3 Overview Archive::Zip::Archive objects are what you ordinarily deal with. These maintain the structure of a zip file, without necessarily holding data. When a zip is read from a disk file, the (possibly compressed) data still lives in the file, not in memory. Archive members hold information about the individual members, but not (usually) the actual member data. When the zip is written to a (different) file, the member data is compressed or copied as needed. It is possible to make archive members whose data is held in a string in memory, but this is not done when a zip file is read. Directory members don't have any data. =head2 Inheritance Exporter Archive::Zip Common base class, has defs. Archive::Zip::Archive A Zip archive. Archive::Zip::Member Abstract superclass for all members. Archive::Zip::StringMember Member made from a string Archive::Zip::FileMember Member made from an external file Archive::Zip::ZipFileMember Member that lives in a zip file Archive::Zip::NewFileMember Member whose data is in a file Archive::Zip::DirectoryMember Member that is a directory =head1 EXPORTS =over 4 =item :CONSTANTS Exports the following constants: FA_MSDOS FA_UNIX GPBF_ENCRYPTED_MASK GPBF_DEFLATING_COMPRESSION_MASK GPBF_HAS_DATA_DESCRIPTOR_MASK COMPRESSION_STORED COMPRESSION_DEFLATED IFA_TEXT_FILE_MASK IFA_TEXT_FILE IFA_BINARY_FILE COMPRESSION_LEVEL_NONE COMPRESSION_LEVEL_DEFAULT COMPRESSION_LEVEL_FASTEST COMPRESSION_LEVEL_BEST_COMPRESSION =item :MISC_CONSTANTS Exports the following constants (only necessary for extending the module): FA_AMIGA FA_VAX_VMS FA_VM_CMS FA_ATARI_ST FA_OS2_HPFS FA_MACINTOSH FA_Z_SYSTEM FA_CPM FA_WINDOWS_NTFS GPBF_IMPLODING_8K_SLIDING_DICTIONARY_MASK GPBF_IMPLODING_3_SHANNON_FANO_TREES_MASK GPBF_IS_COMPRESSED_PATCHED_DATA_MASK COMPRESSION_SHRUNK DEFLATING_COMPRESSION_NORMAL DEFLATING_COMPRESSION_MAXIMUM DEFLATING_COMPRESSION_FAST DEFLATING_COMPRESSION_SUPER_FAST COMPRESSION_REDUCED_1 COMPRESSION_REDUCED_2 COMPRESSION_REDUCED_3 COMPRESSION_REDUCED_4 COMPRESSION_IMPLODED COMPRESSION_TOKENIZED COMPRESSION_DEFLATED_ENHANCED COMPRESSION_PKWARE_DATA_COMPRESSION_LIBRARY_IMPLODED =item :ERROR_CODES Explained below. Returned from most methods. AZ_OK AZ_STREAM_END AZ_ERROR AZ_FORMAT_ERROR AZ_IO_ERROR =back =head1 ERROR CODES Many of the methods in Archive::Zip return error codes. These are implemented as inline subroutines, using the C pragma. They can be imported into your namespace using the C<:ERROR_CODES> tag: use Archive::Zip qw( :ERROR_CODES ); ... unless ( $zip->read( 'myfile.zip' ) == AZ_OK ) { die "whoops!"; } =over 4 =item AZ_OK (0) Everything is fine. =item AZ_STREAM_END (1) The read stream (or central directory) ended normally. =item AZ_ERROR (2) There was some generic kind of error. =item AZ_FORMAT_ERROR (3) There is a format error in a ZIP file being read. =item AZ_IO_ERROR (4) There was an IO error. =back =head2 Compression Archive::Zip allows each member of a ZIP file to be compressed (using the Deflate algorithm) or uncompressed. Other compression algorithms that some versions of ZIP have been able to produce are not supported. Each member has two compression methods: the one it's stored as (this is always COMPRESSION_STORED for string and external file members), and the one you desire for the member in the zip file. These can be different, of course, so you can make a zip member that is not compressed out of one that is, and vice versa. You can inquire about the current compression and set the desired compression method: my $member = $zip->memberNamed( 'xyz.txt' ); $member->compressionMethod(); # return current compression # set to read uncompressed $member->desiredCompressionMethod( COMPRESSION_STORED ); # set to read compressed $member->desiredCompressionMethod( COMPRESSION_DEFLATED ); There are two different compression methods: =over 4 =item COMPRESSION_STORED File is stored (no compression) =item COMPRESSION_DEFLATED File is Deflated =back =head2 Compression Levels If a member's desiredCompressionMethod is COMPRESSION_DEFLATED, you can choose different compression levels. This choice may affect the speed of compression and decompression, as well as the size of the compressed member data. $member->desiredCompressionLevel( 9 ); The levels given can be: =over 4 =item * 0 or COMPRESSION_LEVEL_NONE This is the same as saying $member->desiredCompressionMethod( COMPRESSION_STORED ); =item * 1 .. 9 1 gives the best speed and worst compression, and 9 gives the best compression and worst speed. =item * COMPRESSION_LEVEL_FASTEST This is a synonym for level 1. =item * COMPRESSION_LEVEL_BEST_COMPRESSION This is a synonym for level 9. =item * COMPRESSION_LEVEL_DEFAULT This gives a good compromise between speed and compression, and is currently equivalent to 6 (this is in the zlib code). This is the level that will be used if not specified. =back =head1 Archive::Zip Methods The Archive::Zip class (and its invisible subclass Archive::Zip::Archive) implement generic zip file functionality. Creating a new Archive::Zip object actually makes an Archive::Zip::Archive object, but you don't have to worry about this unless you're subclassing. =head2 Constructor =over 4 =item new( [$fileName] ) =item new( { filename => $fileName } ) Make a new, empty zip archive. my $zip = Archive::Zip->new(); If an additional argument is passed, new() will call read() to read the contents of an archive: my $zip = Archive::Zip->new( 'xyz.zip' ); If a filename argument is passed and the read fails for any reason, new will return undef. For this reason, it may be better to call read separately. =back =head2 Zip Archive Utility Methods These Archive::Zip methods may be called as functions or as object methods. Do not call them as class methods: $zip = Archive::Zip->new(); $crc = Archive::Zip::computeCRC32( 'ghijkl' ); # OK $crc = $zip->computeCRC32( 'ghijkl' ); # also OK $crc = Archive::Zip->computeCRC32( 'ghijkl' ); # NOT OK =over 4 =item Archive::Zip::computeCRC32( $string [, $crc] ) =item Archive::Zip::computeCRC32( { string => $string [, checksum => $crc ] } ) This is a utility function that uses the Compress::Raw::Zlib CRC routine to compute a CRC-32. You can get the CRC of a string: $crc = Archive::Zip::computeCRC32( $string ); Or you can compute the running CRC: $crc = 0; $crc = Archive::Zip::computeCRC32( 'abcdef', $crc ); $crc = Archive::Zip::computeCRC32( 'ghijkl', $crc ); =item Archive::Zip::setChunkSize( $number ) =item Archive::Zip::setChunkSize( { chunkSize => $number } ) Report or change chunk size used for reading and writing. This can make big differences in dealing with large files. Currently, this defaults to 32K. This also changes the chunk size used for Compress::Raw::Zlib. You must call setChunkSize() before reading or writing. This is not exportable, so you must call it like: Archive::Zip::setChunkSize( 4096 ); or as a method on a zip (though this is a global setting). Returns old chunk size. =item Archive::Zip::chunkSize() Returns the current chunk size: my $chunkSize = Archive::Zip::chunkSize(); =item Archive::Zip::setErrorHandler( \&subroutine ) =item Archive::Zip::setErrorHandler( { subroutine => \&subroutine } ) Change the subroutine called with error strings. This defaults to \&Carp::carp, but you may want to change it to get the error strings. This is not exportable, so you must call it like: Archive::Zip::setErrorHandler( \&myErrorHandler ); If myErrorHandler is undef, resets handler to default. Returns old error handler. Note that if you call Carp::carp or a similar routine or if you're chaining to the default error handler from your error handler, you may want to increment the number of caller levels that are skipped (do not just set it to a number): $Carp::CarpLevel++; =item Archive::Zip::tempFile( [ $tmpdir ] ) =item Archive::Zip::tempFile( { tempDir => $tmpdir } ) Create a uniquely named temp file. It will be returned open for read/write. If C<$tmpdir> is given, it is used as the name of a directory to create the file in. If not given, creates the file using C. Generally, you can override this choice using the $ENV{TMPDIR} environment variable. But see the L documentation for your system. Note that on many systems, if you're running in taint mode, then you must make sure that C<$ENV{TMPDIR}> is untainted for it to be used. Will I create C<$tmpdir> if it does not exist (this is a change from prior versions!). Returns file handle and name: my ($fh, $name) = Archive::Zip::tempFile(); my ($fh, $name) = Archive::Zip::tempFile('myTempDir'); my $fh = Archive::Zip::tempFile(); # if you don't need the name =back =head2 Zip Archive Accessors =over 4 =item members() Return a copy of the members array my @members = $zip->members(); =item numberOfMembers() Return the number of members I have =item memberNames() Return a list of the (internal) file names of the zip members =item memberNamed( $string ) =item memberNamed( { zipName => $string } ) Return ref to member whose filename equals given filename or undef. C<$string> must be in Zip (Unix) filename format. =item membersMatching( $regex ) =item membersMatching( { regex => $regex } ) Return array of members whose filenames match given regular expression in list context. Returns number of matching members in scalar context. my @textFileMembers = $zip->membersMatching( '.*\.txt' ); # or my $numberOfTextFiles = $zip->membersMatching( '.*\.txt' ); =item diskNumber() Return the disk that I start on. Not used for writing zips, but might be interesting if you read a zip in. This should be 0, as Archive::Zip does not handle multi-volume archives. =item diskNumberWithStartOfCentralDirectory() Return the disk number that holds the beginning of the central directory. Not used for writing zips, but might be interesting if you read a zip in. This should be 0, as Archive::Zip does not handle multi-volume archives. =item numberOfCentralDirectoriesOnThisDisk() Return the number of CD structures in the zipfile last read in. Not used for writing zips, but might be interesting if you read a zip in. =item numberOfCentralDirectories() Return the number of CD structures in the zipfile last read in. Not used for writing zips, but might be interesting if you read a zip in. =item centralDirectorySize() Returns central directory size, as read from an external zip file. Not used for writing zips, but might be interesting if you read a zip in. =item centralDirectoryOffsetWRTStartingDiskNumber() Returns the offset into the zip file where the CD begins. Not used for writing zips, but might be interesting if you read a zip in. =item zipfileComment( [ $string ] ) =item zipfileComment( [ { comment => $string } ] ) Get or set the zipfile comment. Returns the old comment. print $zip->zipfileComment(); $zip->zipfileComment( 'New Comment' ); =item eocdOffset() Returns the (unexpected) number of bytes between where the EOCD was found and where it expected to be. This is normally 0, but would be positive if something (a virus, perhaps) had added bytes somewhere before the EOCD. Not used for writing zips, but might be interesting if you read a zip in. Here is an example of how you can diagnose this: my $zip = Archive::Zip->new('somefile.zip'); if ($zip->eocdOffset()) { warn "A virus has added ", $zip->eocdOffset, " bytes of garbage\n"; } The C is used to adjust the starting position of member headers, if necessary. =item fileName() Returns the name of the file last read from. If nothing has been read yet, returns an empty string; if read from a file handle, returns the handle in string form. =back =head2 Zip Archive Member Operations Various operations on a zip file modify members. When a member is passed as an argument, you can either use a reference to the member itself, or the name of a member. Of course, using the name requires that names be unique within a zip (this is not enforced). =over 4 =item removeMember( $memberOrName ) =item removeMember( { memberOrZipName => $memberOrName } ) Remove and return the given member, or match its name and remove it. Returns undef if member or name does not exist in this Zip. No-op if member does not belong to this zip. =item replaceMember( $memberOrName, $newMember ) =item replaceMember( { memberOrZipName => $memberOrName, newMember => $newMember } ) Remove and return the given member, or match its name and remove it. Replace with new member. Returns undef if member or name does not exist in this Zip, or if C<$newMember> is undefined. It is an (undiagnosed) error to provide a C<$newMember> that is a member of the zip being modified. my $member1 = $zip->removeMember( 'xyz' ); my $member2 = $zip->replaceMember( 'abc', $member1 ); # now, $member2 (named 'abc') is not in $zip, # and $member1 (named 'xyz') is, having taken $member2's place. =item extractMember( $memberOrName [, $extractedName ] ) =item extractMember( { memberOrZipName => $memberOrName [, name => $extractedName ] } ) Extract the given member, or match its name and extract it. Returns undef if member does not exist in this Zip. If optional second arg is given, use it as the name of the extracted member. Otherwise, the internal filename of the member is used as the name of the extracted file or directory. If you pass C<$extractedName>, it should be in the local file system's format. All necessary directories will be created. Returns C on success. =item extractMemberWithoutPaths( $memberOrName [, $extractedName ] ) =item extractMemberWithoutPaths( { memberOrZipName => $memberOrName [, name => $extractedName ] } ) Extract the given member, or match its name and extract it. Does not use path information (extracts into the current directory). Returns undef if member does not exist in this Zip. If optional second arg is given, use it as the name of the extracted member (its paths will be deleted too). Otherwise, the internal filename of the member (minus paths) is used as the name of the extracted file or directory. Returns C on success. =item addMember( $member ) =item addMember( { member => $member } ) Append a member (possibly from another zip file) to the zip file. Returns the new member. Generally, you will use addFile(), addDirectory(), addFileOrDirectory(), addString(), or read() to add members. # Move member named 'abc' to end of zip: my $member = $zip->removeMember( 'abc' ); $zip->addMember( $member ); =item updateMember( $memberOrName, $fileName ) =item updateMember( { memberOrZipName => $memberOrName, name => $fileName } ) Update a single member from the file or directory named C<$fileName>. Returns the (possibly added or updated) member, if any; C on errors. The comparison is based on C and (in the case of a non-directory) the size of the file. =item addFile( $fileName [, $newName, $compressionLevel ] ) =item addFile( { filename => $fileName [, zipName => $newName, compressionLevel => $compressionLevel } ] ) Append a member whose data comes from an external file, returning the member or undef. The member will have its file name set to the name of the external file, and its desiredCompressionMethod set to COMPRESSION_DEFLATED. The file attributes and last modification time will be set from the file. If the name given does not represent a readable plain file or symbolic link, undef will be returned. C<$fileName> must be in the format required for the local file system. The optional C<$newName> argument sets the internal file name to something different than the given $fileName. C<$newName>, if given, must be in Zip name format (i.e. Unix). The text mode bit will be set if the contents appears to be text (as returned by the C<-T> perl operator). I that you should not (generally) use absolute path names in zip member names, as this will cause problems with some zip tools as well as introduce a security hole and make the zip harder to use. =item addDirectory( $directoryName [, $fileName ] ) =item addDirectory( { directoryName => $directoryName [, zipName => $fileName ] } ) Append a member created from the given directory name. The directory name does not have to name an existing directory. If the named directory exists, the file modification time and permissions are set from the existing directory, otherwise they are set to now and permissive default permissions. C<$directoryName> must be in local file system format. The optional second argument sets the name of the archive member (which defaults to C<$directoryName>). If given, it must be in Zip (Unix) format. Returns the new member. =item addFileOrDirectory( $name [, $newName, $compressionLevel ] ) =item addFileOrDirectory( { name => $name [, zipName => $newName, compressionLevel => $compressionLevel ] } ) Append a member from the file or directory named $name. If $newName is given, use it for the name of the new member. Will add or remove trailing slashes from $newName as needed. C<$name> must be in local file system format. The optional second argument sets the name of the archive member (which defaults to C<$name>). If given, it must be in Zip (Unix) format. =item addString( $stringOrStringRef, $name, [$compressionLevel] ) =item addString( { string => $stringOrStringRef [, zipName => $name, compressionLevel => $compressionLevel ] } ) Append a member created from the given string or string reference. The name is given by the second argument. Returns the new member. The last modification time will be set to now, and the file attributes will be set to permissive defaults. my $member = $zip->addString( 'This is a test', 'test.txt' ); =item contents( $memberOrMemberName [, $newContents ] ) =item contents( { memberOrZipName => $memberOrMemberName [, contents => $newContents ] } ) Returns the uncompressed data for a particular member, or undef. print "xyz.txt contains " . $zip->contents( 'xyz.txt' ); Also can change the contents of a member: $zip->contents( 'xyz.txt', 'This is the new contents' ); If called expecting an array as the return value, it will include the status as the second value in the array. ($content, $status) = $zip->contents( 'xyz.txt'); =back =head2 Zip Archive I/O operations A Zip archive can be written to a file or file handle, or read from one. =over 4 =item writeToFileNamed( $fileName ) =item writeToFileNamed( { fileName => $fileName } ) Write a zip archive to named file. Returns C on success. my $status = $zip->writeToFileNamed( 'xx.zip' ); die "error somewhere" if $status != AZ_OK; Note that if you use the same name as an existing zip file that you read in, you will clobber ZipFileMembers. So instead, write to a different file name, then delete the original. If you use the C or C methods, you can re-write the original zip in this way. C<$fileName> should be a valid file name on your system. =item writeToFileHandle( $fileHandle [, $seekable] ) Write a zip archive to a file handle. Return AZ_OK on success. The optional second arg tells whether or not to try to seek backwards to re-write headers. If not provided, it is set if the Perl C<-f> test returns true. This could fail on some operating systems, though. my $fh = IO::File->new( 'someFile.zip', 'w' ); unless ( $zip->writeToFileHandle( $fh ) == AZ_OK ) { # error handling } If you pass a file handle that is not seekable (like if you're writing to a pipe or a socket), pass a false second argument: my $fh = IO::File->new( '| cat > somefile.zip', 'w' ); $zip->writeToFileHandle( $fh, 0 ); # fh is not seekable If this method fails during the write of a member, that member and all following it will return false from C. See writeCentralDirectory() for a way to deal with this. If you want, you can write data to the file handle before passing it to writeToFileHandle(); this could be used (for instance) for making self-extracting archives. However, this only works reliably when writing to a real file (as opposed to STDOUT or some other possible non-file). See examples/selfex.pl for how to write a self-extracting archive. =item writeCentralDirectory( $fileHandle [, $offset ] ) =item writeCentralDirectory( { fileHandle => $fileHandle [, offset => $offset ] } ) Writes the central directory structure to the given file handle. Returns AZ_OK on success. If given an $offset, will seek to that point before writing. This can be used for recovery in cases where writeToFileHandle or writeToFileNamed returns an IO error because of running out of space on the destination file. You can truncate the zip by seeking backwards and then writing the directory: my $fh = IO::File->new( 'someFile.zip', 'w' ); my $retval = $zip->writeToFileHandle( $fh ); if ( $retval == AZ_IO_ERROR ) { my @unwritten = grep { not $_->wasWritten() } $zip->members(); if (@unwritten) { $zip->removeMember( $member ) foreach my $member ( @unwritten ); $zip->writeCentralDirectory( $fh, $unwritten[0]->writeLocalHeaderRelativeOffset()); } } =item overwriteAs( $newName ) =item overwriteAs( { filename => $newName } ) Write the zip to the specified file, as safely as possible. This is done by first writing to a temp file, then renaming the original if it exists, then renaming the temp file, then deleting the renamed original if it exists. Returns AZ_OK if successful. =item overwrite() Write back to the original zip file. See overwriteAs() above. If the zip was not ever read from a file, this generates an error. =item read( $fileName ) =item read( { filename => $fileName } ) Read zipfile headers from a zip file, appending new members. Returns C or error code. my $zipFile = Archive::Zip->new(); my $status = $zipFile->read( '/some/FileName.zip' ); =item readFromFileHandle( $fileHandle, $filename ) =item readFromFileHandle( { fileHandle => $fileHandle, filename => $filename } ) Read zipfile headers from an already-opened file handle, appending new members. Does not close the file handle. Returns C or error code. Note that this requires a seekable file handle; reading from a stream is not yet supported. my $fh = IO::File->new( '/some/FileName.zip', 'r' ); my $zip1 = Archive::Zip->new(); my $status = $zip1->readFromFileHandle( $fh ); my $zip2 = Archive::Zip->new(); $status = $zip2->readFromFileHandle( $fh ); =back =head2 Zip Archive Tree operations These used to be in Archive::Zip::Tree but got moved into Archive::Zip. They enable operation on an entire tree of members or files. A usage example: use Archive::Zip; my $zip = Archive::Zip->new(); # add all readable files and directories below . as xyz/* $zip->addTree( '.', 'xyz' ); # add all readable plain files below /abc as def/* $zip->addTree( '/abc', 'def', sub { -f && -r } ); # add all .c files below /tmp as stuff/* $zip->addTreeMatching( '/tmp', 'stuff', '\.c$' ); # add all .o files below /tmp as stuff/* if they aren't writable $zip->addTreeMatching( '/tmp', 'stuff', '\.o$', sub { ! -w } ); # add all .so files below /tmp that are smaller than 200 bytes as stuff/* $zip->addTreeMatching( '/tmp', 'stuff', '\.o$', sub { -s < 200 } ); # and write them into a file $zip->writeToFileNamed('xxx.zip'); # now extract the same files into /tmpx $zip->extractTree( 'stuff', '/tmpx' ); =over 4 =item $zip->addTree( $root, $dest [, $pred, $compressionLevel ] ) -- Add tree of files to a zip =item $zip->addTree( { root => $root, zipName => $dest [, select => $pred, compressionLevel => $compressionLevel ] ) C<$root> is the root of the tree of files and directories to be added. It is a valid directory name on your system. C<$dest> is the name for the root in the zip file (undef or blank means to use relative pathnames). It is a valid ZIP directory name (that is, it uses forward slashes (/) for separating directory components). C<$pred> is an optional subroutine reference to select files: it is passed the name of the prospective file or directory using C<$_>, and if it returns true, the file or directory will be included. The default is to add all readable files and directories. For instance, using my $pred = sub { /\.txt/ }; $zip->addTree( '.', '', $pred ); will add all the .txt files in and below the current directory, using relative names, and making the names identical in the zipfile: original name zip member name ./xyz xyz ./a/ a/ ./a/b a/b To translate absolute to relative pathnames, just pass them in: $zip->addTree( '/c/d', 'a' ); original name zip member name /c/d/xyz a/xyz /c/d/a/ a/a/ /c/d/a/b a/a/b Returns AZ_OK on success. Note that this will not follow symbolic links to directories. Note also that this does not check for the validity of filenames. Note that you generally I want to make zip archive member names absolute. =item $zip->addTreeMatching( $root, $dest, $pattern [, $pred, $compressionLevel ] ) =item $zip->addTreeMatching( { root => $root, zipName => $dest, pattern => $pattern [, select => $pred, compressionLevel => $compressionLevel ] } ) $root is the root of the tree of files and directories to be added $dest is the name for the root in the zip file (undef means to use relative pathnames) $pattern is a (non-anchored) regular expression for filenames to match $pred is an optional subroutine reference to select files: it is passed the name of the prospective file or directory in C<$_>, and if it returns true, the file or directory will be included. The default is to add all readable files and directories. To add all files in and below the current directory whose names end in C<.pl>, and make them extract into a subdirectory named C, do this: $zip->addTreeMatching( '.', 'xyz', '\.pl$' ) To add all I files in and below the directory named C whose names end in C<.pl>, and make them extract into a subdirectory named C, do this: $zip->addTreeMatching( '/abc', 'xyz', '\.pl$', sub { -w } ) Returns AZ_OK on success. Note that this will not follow symbolic links to directories. =item $zip->updateTree( $root [, $dest , $pred , $mirror, $compressionLevel ] ); =item $zip->updateTree( { root => $root [, zipName => $dest, select => $pred, mirror => $mirror, compressionLevel => $compressionLevel ] } ); Update a zip file from a directory tree. C takes the same arguments as C, but first checks to see whether the file or directory already exists in the zip file, and whether it has been changed. If the fourth argument C<$mirror> is true, then delete all my members if corresponding files were not found. Returns an error code or AZ_OK if all is well. =item $zip->extractTree( [ $root, $dest, $volume } ] ) =item $zip->extractTree( [ { root => $root, zipName => $dest, volume => $volume } ] ) If you don't give any arguments at all, will extract all the files in the zip with their original names. If you supply one argument for C<$root>, C will extract all the members whose names start with C<$root> into the current directory, stripping off C<$root> first. C<$root> is in Zip (Unix) format. For instance, $zip->extractTree( 'a' ); when applied to a zip containing the files: a/x a/b/c ax/d/e d/e will extract: a/x as ./x a/b/c as ./b/c If you give two arguments, C extracts all the members whose names start with C<$root>. It will translate C<$root> into C<$dest> to construct the destination file name. C<$root> and C<$dest> are in Zip (Unix) format. For instance, $zip->extractTree( 'a', 'd/e' ); when applied to a zip containing the files: a/x a/b/c ax/d/e d/e will extract: a/x to d/e/x a/b/c to d/e/b/c and ignore ax/d/e and d/e If you give three arguments, C extracts all the members whose names start with C<$root>. It will translate C<$root> into C<$dest> to construct the destination file name, and then it will convert to local file system format, using C<$volume> as the name of the destination volume. C<$root> and C<$dest> are in Zip (Unix) format. C<$volume> is in local file system format. For instance, under Windows, $zip->extractTree( 'a', 'd/e', 'f:' ); when applied to a zip containing the files: a/x a/b/c ax/d/e d/e will extract: a/x to f:d/e/x a/b/c to f:d/e/b/c and ignore ax/d/e and d/e If you want absolute paths (the prior example used paths relative to the current directory on the destination volume, you can specify these in C<$dest>: $zip->extractTree( 'a', '/d/e', 'f:' ); when applied to a zip containing the files: a/x a/b/c ax/d/e d/e will extract: a/x to f:\d\e\x a/b/c to f:\d\e\b\c and ignore ax/d/e and d/e Returns an error code or AZ_OK if everything worked OK. =back =head1 Archive::Zip Global Variables =over 4 =item $Archive::Zip::UNICODE This variable governs how Unicode file and directory names are added to or extracted from an archive. If set, file and directory names are considered to be UTF-8 encoded. This is I. Please report problems. { local $Archive::Zip::UNICODE = 1; $zip->addFile('Déjà vu.txt'); } =back =head1 MEMBER OPERATIONS =head2 Member Class Methods Several constructors allow you to construct members without adding them to a zip archive. These work the same as the addFile(), addDirectory(), and addString() zip instance methods described above, but they don't add the new members to a zip. =over 4 =item Archive::Zip::Member->newFromString( $stringOrStringRef [, $fileName ] ) =item Archive::Zip::Member->newFromString( { string => $stringOrStringRef [, zipName => $fileName ] ) Construct a new member from the given string. Returns undef on error. my $member = Archive::Zip::Member->newFromString( 'This is a test', =item newFromFile( $fileName [, $zipName ] ) =item newFromFile( { filename => $fileName [, zipName => $zipName ] } ) Construct a new member from the given file. Returns undef on error. my $member = Archive::Zip::Member->newFromFile( 'xyz.txt' ); =item newDirectoryNamed( $directoryName [, $zipname ] ) =item newDirectoryNamed( { directoryName => $directoryName [, zipName => $zipname ] } ) Construct a new member from the given directory. C<$directoryName> must be a valid name on your file system; it does not have to exist. If given, C<$zipname> will be the name of the zip member; it must be a valid Zip (Unix) name. If not given, it will be converted from C<$directoryName>. Returns undef on error. my $member = Archive::Zip::Member->newDirectoryNamed( 'CVS/' ); =back =head2 Member Simple accessors These methods get (and/or set) member attribute values. =over 4 =item versionMadeBy() Gets the field from the member header. =item fileAttributeFormat( [ $format ] ) =item fileAttributeFormat( [ { format => $format ] } ) Gets or sets the field from the member header. These are C values. =item versionNeededToExtract() Gets the field from the member header. =item bitFlag() Gets the general purpose bit field from the member header. This is where the C bits live. =item compressionMethod() Returns the member compression method. This is the method that is currently being used to compress the member data. This will be COMPRESSION_STORED for added string or file members, or any of the C values for members from a zip file. However, this module can only handle members whose data is in COMPRESSION_STORED or COMPRESSION_DEFLATED format. =item desiredCompressionMethod( [ $method ] ) =item desiredCompressionMethod( [ { compressionMethod => $method } ] ) Get or set the member's C. This is the compression method that will be used when the member is written. Returns prior desiredCompressionMethod. Only COMPRESSION_DEFLATED or COMPRESSION_STORED are valid arguments. Changing to COMPRESSION_STORED will change the member desiredCompressionLevel to 0; changing to COMPRESSION_DEFLATED will change the member desiredCompressionLevel to COMPRESSION_LEVEL_DEFAULT. =item desiredCompressionLevel( [ $level ] ) =item desiredCompressionLevel( [ { compressionLevel => $level } ] ) Get or set the member's desiredCompressionLevel This is the method that will be used to write. Returns prior desiredCompressionLevel. Valid arguments are 0 through 9, COMPRESSION_LEVEL_NONE, COMPRESSION_LEVEL_DEFAULT, COMPRESSION_LEVEL_BEST_COMPRESSION, and COMPRESSION_LEVEL_FASTEST. 0 or COMPRESSION_LEVEL_NONE will change the desiredCompressionMethod to COMPRESSION_STORED. All other arguments will change the desiredCompressionMethod to COMPRESSION_DEFLATED. =item externalFileName() Return the member's external file name, if any, or undef. =item fileName() Get or set the member's internal filename. Returns the (possibly new) filename. Names will have backslashes converted to forward slashes, and will have multiple consecutive slashes converted to single ones. =item lastModFileDateTime() Return the member's last modification date/time stamp in MS-DOS format. =item lastModTime() Return the member's last modification date/time stamp, converted to unix localtime format. print "Mod Time: " . scalar( localtime( $member->lastModTime() ) ); =item setLastModFileDateTimeFromUnix() Set the member's lastModFileDateTime from the given unix time. $member->setLastModFileDateTimeFromUnix( time() ); =item internalFileAttributes() Return the internal file attributes field from the zip header. This is only set for members read from a zip file. =item externalFileAttributes() Return member attributes as read from the ZIP file. Note that these are NOT UNIX! =item unixFileAttributes( [ $newAttributes ] ) =item unixFileAttributes( [ { attributes => $newAttributes } ] ) Get or set the member's file attributes using UNIX file attributes. Returns old attributes. my $oldAttribs = $member->unixFileAttributes( 0666 ); Note that the return value has more than just the file permissions, so you will have to mask off the lowest bits for comparisons. =item localExtraField( [ $newField ] ) =item localExtraField( [ { field => $newField } ] ) Gets or sets the extra field that was read from the local header. This is not set for a member from a zip file until after the member has been written out. The extra field must be in the proper format. =item cdExtraField( [ $newField ] ) =item cdExtraField( [ { field => $newField } ] ) Gets or sets the extra field that was read from the central directory header. The extra field must be in the proper format. =item extraFields() Return both local and CD extra fields, concatenated. =item fileComment( [ $newComment ] ) =item fileComment( [ { comment => $newComment } ] ) Get or set the member's file comment. =item hasDataDescriptor() Get or set the data descriptor flag. If this is set, the local header will not necessarily have the correct data sizes. Instead, a small structure will be stored at the end of the member data with these values. This should be transparent in normal operation. =item crc32() Return the CRC-32 value for this member. This will not be set for members that were constructed from strings or external files until after the member has been written. =item crc32String() Return the CRC-32 value for this member as an 8 character printable hex string. This will not be set for members that were constructed from strings or external files until after the member has been written. =item compressedSize() Return the compressed size for this member. This will not be set for members that were constructed from strings or external files until after the member has been written. =item uncompressedSize() Return the uncompressed size for this member. =item password( [ $password ] ) Returns the password for this member to be used on decryption. If $password is given, it will set the password for the decryption. =item isEncrypted() Return true if this member is encrypted. The Archive::Zip module does not currently support creation of encrypted members. Decryption works more or less like this: my $zip = Archive::Zip->new; $zip->read ("encrypted.zip"); for my $m (map { $zip->memberNamed ($_) } $zip->memberNames) { $m->password ("secret"); $m->contents; # is "" when password was wrong That shows that the password has to be set per member, and not per archive. This might change in the future. =item isTextFile( [ $flag ] ) =item isTextFile( [ { flag => $flag } ] ) Returns true if I am a text file. Also can set the status if given an argument (then returns old state). Note that this module does not currently do anything with this flag upon extraction or storage. That is, bytes are stored in native format whether or not they came from a text file. =item isBinaryFile() Returns true if I am a binary file. Also can set the status if given an argument (then returns old state). Note that this module does not currently do anything with this flag upon extraction or storage. That is, bytes are stored in native format whether or not they came from a text file. =item extractToFileNamed( $fileName ) =item extractToFileNamed( { name => $fileName } ) Extract me to a file with the given name. The file will be created with default modes. Directories will be created as needed. The C<$fileName> argument should be a valid file name on your file system. Returns AZ_OK on success. =item isDirectory() Returns true if I am a directory. =item writeLocalHeaderRelativeOffset() Returns the file offset in bytes the last time I was written. =item wasWritten() Returns true if I was successfully written. Reset at the beginning of a write attempt. =back =head2 Low-level member data reading It is possible to use lower-level routines to access member data streams, rather than the extract* methods and contents(). For instance, here is how to print the uncompressed contents of a member in chunks using these methods: my ( $member, $status, $bufferRef ); $member = $zip->memberNamed( 'xyz.txt' ); $member->desiredCompressionMethod( COMPRESSION_STORED ); $status = $member->rewindData(); die "error $status" unless $status == AZ_OK; while ( ! $member->readIsDone() ) { ( $bufferRef, $status ) = $member->readChunk(); die "error $status" if $status != AZ_OK && $status != AZ_STREAM_END; # do something with $bufferRef: print $$bufferRef; } $member->endRead(); =over 4 =item readChunk( [ $chunkSize ] ) =item readChunk( [ { chunkSize => $chunkSize } ] ) This reads the next chunk of given size from the member's data stream and compresses or uncompresses it as necessary, returning a reference to the bytes read and a status. If size argument is not given, defaults to global set by Archive::Zip::setChunkSize. Status is AZ_OK on success until the last chunk, where it returns AZ_STREAM_END. Returns C<( \$bytes, $status)>. my ( $outRef, $status ) = $self->readChunk(); print $$outRef if $status != AZ_OK && $status != AZ_STREAM_END; =item rewindData() Rewind data and set up for reading data streams or writing zip files. Can take options for C or C, but this is not likely to be necessary. Subclass overrides should call this method. Returns C on success. =item endRead() Reset the read variables and free the inflater or deflater. Must be called to close files, etc. Returns AZ_OK on success. =item readIsDone() Return true if the read has run out of data or encountered an error. =item contents() Return the entire uncompressed member data or undef in scalar context. When called in array context, returns C<( $string, $status )>; status will be AZ_OK on success: my $string = $member->contents(); # or my ( $string, $status ) = $member->contents(); die "error $status" unless $status == AZ_OK; Can also be used to set the contents of a member (this may change the class of the member): $member->contents( "this is my new contents" ); =item extractToFileHandle( $fh ) =item extractToFileHandle( { fileHandle => $fh } ) Extract (and uncompress, if necessary) the member's contents to the given file handle. Return AZ_OK on success. =back =head1 Archive::Zip::FileMember methods The Archive::Zip::FileMember class extends Archive::Zip::Member. It is the base class for both ZipFileMember and NewFileMember classes. This class adds an C and an C member to keep track of the external file. =over 4 =item externalFileName() Return the member's external filename. =item fh() Return the member's read file handle. Automatically opens file if necessary. =back =head1 Archive::Zip::ZipFileMember methods The Archive::Zip::ZipFileMember class represents members that have been read from external zip files. =over 4 =item diskNumberStart() Returns the disk number that the member's local header resides in. Should be 0. =item localHeaderRelativeOffset() Returns the offset into the zip file where the member's local header is. =item dataOffset() Returns the offset from the beginning of the zip file to the member's data. =back =head1 REQUIRED MODULES L requires several other modules: L L L L L L L L L L L =head1 BUGS AND CAVEATS =head2 When not to use Archive::Zip If you are just going to be extracting zips (and/or other archives) you are recommended to look at using L instead, as it is much easier to use and factors out archive-specific functionality. =head2 Try to avoid IO::Scalar One of the most common ways to use Archive::Zip is to generate Zip files in-memory. Most people have use L for this purpose. Unfortunately, as of 1.11 this module no longer works with L as it incorrectly implements seeking. Anybody using L should consider porting to L, which is smaller, lighter, and is implemented to be perfectly compatible with regular seekable filehandles. Support for L most likely will B be restored in the future, as L itself cannot change the way it is implemented due to back-compatibility issues. =head2 Wrong password for encrypted members When an encrypted member is read using the wrong password, you currently have to re-read the entire archive to try again with the correct password. =head1 TO DO * auto-choosing storing vs compression * extra field hooks (see notes.txt) * check for duplicates on addition/renaming? * Text file extraction (line end translation) * Reading zip files from non-seekable inputs (Perhaps by proxying through IO::String?) * separate unused constants into separate module * cookbook style docs * Handle tainted paths correctly * Work on better compatibility with other IO:: modules * Support encryption * More user-friendly decryption =head1 SUPPORT Bugs should be reported via the CPAN bug tracker L For other issues contact the maintainer =head1 AUTHOR Adam Kennedy Eadamk@cpan.orgE Previously maintained by Steve Peters Esteve@fisharerojo.orgE.

I assume that this is because my documentation is deficient, rather than that people don't read the documentation. So this FAQ is an attempt to cut down on the number of personal answers I have to give. At least I can now say "You I read the FAQ, right?". The questions are not in any particular order. The answers assume the current version of Archive::Zip; some of the answers depend on newly added/fixed functionality. =head1 Install problems on RedHat 8 or 9 with Perl 5.8.0 B Archive::Zip won't install on my RedHat 9 system! It's broke! B This has become something of a FAQ. Basically, RedHat broke some versions of Perl by setting LANG to UTF8. They apparently have a fixed version out as an update. You might try running CPAN or creating your Makefile after exporting the LANG environment variable as C L =head1 Why is my zip file so big? B My zip file is actually bigger than what I stored in it! Why? B Some things to make sure of: =over 4 =item Make sure that you are requesting COMPRESSION_DEFLATED if you are storing strings. $member->desiredCompressionMethod( COMPRESSION_DEFLATED ); =item Don't make lots of little files if you can help it. Since zip computes the compression tables for each member, small members without much entropy won't compress well. Instead, if you've got lots of repeated strings in your data, try to combine them into one big member. =item Make sure that you are requesting COMPRESSION_STORED if you are storing things that are already compressed. If you're storing a .zip, .jpg, .mp3, or other compressed file in a zip, then don't compress them again. They'll get bigger. =back =head1 Sample code? B Can you send me code to do (whatever)? B Have you looked in the C directory yet? It contains: =over 4 =item examples/calcSizes.pl -- How to find out how big a Zip file will be before writing it =item examples/copy.pl -- Copies one Zip file to another =item examples/extract.pl -- extract file(s) from a Zip =item examples/mailZip.pl -- make and mail a zip file =item examples/mfh.pl -- demo for use of MockFileHandle =item examples/readScalar.pl -- shows how to use IO::Scalar as the source of a Zip read =item examples/selfex.pl -- a brief example of a self-extracting Zip =item examples/unzipAll.pl -- uses Archive::Zip::Tree to unzip an entire Zip =item examples/updateZip.pl -- shows how to read/modify/write a Zip =item examples/updateTree.pl -- shows how to update a Zip in place =item examples/writeScalar.pl -- shows how to use IO::Scalar as the destination of a Zip write =item examples/writeScalar2.pl -- shows how to use IO::String as the destination of a Zip write =item examples/zip.pl -- Constructs a Zip file =item examples/zipcheck.pl -- One way to check a Zip file for validity =item examples/zipinfo.pl -- Prints out information about a Zip archive file =item examples/zipGrep.pl -- Searches for text in Zip files =item examples/ziptest.pl -- Lists a Zip file and checks member CRCs =item examples/ziprecent.pl -- Puts recent files into a zipfile =item examples/ziptest.pl -- Another way to check a Zip file for validity =back =head1 Can't Read/modify/write same Zip file B Why can't I open a Zip file, add a member, and write it back? I get an error message when I try. B Because Archive::Zip doesn't (and can't, generally) read file contents into memory, the original Zip file is required to stay around until the writing of the new file is completed. The best way to do this is to write the Zip to a temporary file and then rename the temporary file to have the old name (possibly after deleting the old one). Archive::Zip v1.02 added the archive methods C and C to do this simply and carefully. See C for an example of this technique. =head1 File creation time not set B Upon extracting files, I see that their modification (and access) times are set to the time in the Zip archive. However, their creation time is not set to the same time. Why? B Mostly because Perl doesn't give cross-platform access to I. Indeed, many systems (like Unix) don't support such a concept. However, if yours does, you can easily set it. Get the modification time from the member using C. =head1 Can't use Archive::Zip on gzip files B Can I use Archive::Zip to extract Unix gzip files? B No. There is a distinction between Unix gzip files, and Zip archives that also can use the gzip compression. Depending on the format of the gzip file, you can use L, or L to decompress it (and de-archive it in the case of Tar files). You can unzip PKZIP/WinZip/etc/ archives using Archive::Zip (that's what it's for) as long as any compressed members are compressed using Deflate compression. =head1 Add a directory/tree to a Zip B How can I add a directory (or tree) full of files to a Zip? B You can use the Archive::Zip::addTree*() methods: use Archive::Zip; my $zip = Archive::Zip->new(); # add all readable files and directories below . as xyz/* $zip->addTree( '.', 'xyz' ); # add all readable plain files below /abc as def/* $zip->addTree( '/abc', 'def', sub { -f && -r } ); # add all .c files below /tmp as stuff/* $zip->addTreeMatching( '/tmp', 'stuff', '\.c$' ); # add all .o files below /tmp as stuff/* if they aren't writable $zip->addTreeMatching( '/tmp', 'stuff', '\.o$', sub { ! -w } ); # add all .so files below /tmp that are smaller than 200 bytes as stuff/* $zip->addTreeMatching( '/tmp', 'stuff', '\.o$', sub { -s < 200 } ); # and write them into a file $zip->writeToFileNamed('xxx.zip'); =head1 Extract a directory/tree B How can I extract some (or all) files from a Zip into a different directory? B You can use the Archive::Zip::extractTree() method: ??? || # now extract the same files into /tmpx $zip->extractTree( 'stuff', '/tmpx' ); =head1 Update a directory/tree B How can I update a Zip from a directory tree, adding or replacing only the newer files? B You can use the Archive::Zip::updateTree() method that was added in version 1.09. =head1 Zip times might be off by 1 second B It bothers me greatly that my file times are wrong by one second about half the time. Why don't you do something about it? B Get over it. This is a result of the Zip format storing times in DOS format, which has a resolution of only two seconds. =head1 Zip times don't include time zone information B My file times don't respect time zones. What gives? B If this is important to you, please submit patches to read the various Extra Fields that encode times with time zones. I'm just using the DOS Date/Time, which doesn't have a time zone. =head1 How do I make a self-extracting Zip B I want to make a self-extracting Zip file. Can I do this? B Yes. You can write a self-extracting archive stub (that is, a version of unzip) to the output filehandle that you pass to writeToFileHandle(). See examples/selfex.pl for how to write a self-extracting archive. However, you should understand that this will only work on one kind of platform (the one for which the stub was compiled). =head1 How can I deal with Zips with prepended garbage (i.e. from Sircam) B How can I tell if a Zip has been damaged by adding garbage to the beginning or inside the file? B I added code for this for the Amavis virus scanner. You can query archives for their 'eocdOffset' property, which should be 0: if ($zip->eocdOffset > 0) { warn($zip->eocdOffset . " bytes of garbage at beginning or within Zip") } When members are extracted, this offset will be used to adjust the start of the member if necessary. =head1 Can't extract Shrunk files B I'm trying to extract a file out of a Zip produced by PKZIP, and keep getting this error message: error: Unsupported compression combination: read 6, write 0 B You can't uncompress this archive member. Archive::Zip only supports uncompressed members, and compressed members that are compressed using the compression supported by Compress::Raw::Zlib. That means only Deflated and Stored members. Your file is compressed using the Shrink format, which is not supported by Compress::Raw::Zlib. You could, perhaps, use a command-line UnZip program (like the Info-Zip one) to extract this. =head1 Can't do decryption B How do I decrypt encrypted Zip members? B With some other program or library. Archive::Zip doesn't support decryption, and probably never will (unless I write it). =head1 How to test file integrity? B How can Archive::Zip can test the validity of a Zip file? B If you try to decompress the file, the gzip streams will report errors if you have garbage. Most of the time. If you try to open the file and a central directory structure can't be found, an error will be reported. When a file is being read, if we can't find a proper PK.. signature in the right places we report a format error. If there is added garbage at the beginning of a Zip file (as inserted by some viruses), you can find out about it, but Archive::Zip will ignore it, and you can still use the archive. When it gets written back out the added stuff will be gone. There are two ready-to-use utilities in the examples directory that can be used to test file integrity, or that you can use as examples for your own code: =over 4 =item examples/zipcheck.pl shows how to use an attempted extraction to test a file. =item examples/ziptest.pl shows how to test CRCs in a file. =back =head1 Duplicate files in Zip? B Archive::Zip let me put the same file in my Zip twice! Why don't you prevent this? B As far as I can tell, this is not disallowed by the Zip spec. If you think it's a bad idea, check for it yourself: $zip->addFile($someFile, $someName) unless $zip->memberNamed($someName); I can even imagine cases where this might be useful (for instance, multiple versions of files). =head1 File ownership/permissions/ACLS/etc B Why doesn't Archive::Zip deal with file ownership, ACLs, etc.? B There is no standard way to represent these in the Zip file format. If you want to send me code to properly handle the various extra fields that have been used to represent these through the years, I'll look at it. =head1 I can't compile but ActiveState only has an old version of Archive::Zip B I've only installed modules using ActiveState's PPM program and repository. But they have a much older version of Archive::Zip than is in CPAN. Will you send me a newer PPM? B Probably not, unless I get lots of extra time. But there's no reason you can't install the version from CPAN. Archive::Zip is pure Perl, so all you need is NMAKE, which you can get for free from Microsoft (see the FAQ in the ActiveState documentation for details on how to install CPAN modules). =head1 My JPEGs (or MP3's) don't compress when I put them into Zips! B How come my JPEGs and MP3's don't compress much when I put them into Zips? B Because they're already compressed. =head1 Under Windows, things lock up/get damaged B I'm using Windows. When I try to use Archive::Zip, my machine locks up/makes funny sounds/displays a BSOD/corrupts data. How can I fix this? B First, try the newest version of Compress::Raw::Zlib. I know of Windows-related problems prior to v1.14 of that library. =head1 Zip contents in a scalar B I want to read a Zip file from (or write one to) a scalar variable instead of a file. How can I do this? B Use C and the C and C methods. See C and C. =head1 Reading from streams B How do I read from a stream (like for the Info-Zip C program)? B This is not currently supported, though writing to a stream is. usr/share/perl5/vendor_perl/Archive/Zip/BufferedFileHandle.pm0100444000000000000000000000534111707176624023171 0ustar rootrootpackage Archive::Zip::BufferedFileHandle; # File handle that uses a string internally and can seek # This is given as a demo for getting a zip file written # to a string. # I probably should just use IO::Scalar instead. # Ned Konz, March 2000 use strict; use IO::File; use Carp; use vars qw{$VERSION}; BEGIN { $VERSION = '1.31_04'; $VERSION = eval $VERSION; } sub new { my $class = shift || __PACKAGE__; $class = ref($class) || $class; my $self = bless( { content => '', position => 0, size => 0 }, $class ); return $self; } # Utility method to read entire file sub readFromFile { my $self = shift; my $fileName = shift; my $fh = IO::File->new( $fileName, "r" ); CORE::binmode($fh); if ( !$fh ) { Carp::carp("Can't open $fileName: $!\n"); return undef; } local $/ = undef; $self->{content} = <$fh>; $self->{size} = length( $self->{content} ); return $self; } sub contents { my $self = shift; if (@_) { $self->{content} = shift; $self->{size} = length( $self->{content} ); } return $self->{content}; } sub binmode { 1 } sub close { 1 } sub opened { 1 } sub eof { my $self = shift; return $self->{position} >= $self->{size}; } sub seek { my $self = shift; my $pos = shift; my $whence = shift; # SEEK_SET if ( $whence == 0 ) { $self->{position} = $pos; } # SEEK_CUR elsif ( $whence == 1 ) { $self->{position} += $pos; } # SEEK_END elsif ( $whence == 2 ) { $self->{position} = $self->{size} + $pos; } else { return 0; } return 1; } sub tell { return shift->{position}; } # Copy my data to given buffer sub read { my $self = shift; my $buf = \( $_[0] ); shift; my $len = shift; my $offset = shift || 0; $$buf = '' if not defined($$buf); my $bytesRead = ( $self->{position} + $len > $self->{size} ) ?

Everyone is permitted to copy and distribute verbatim copies of this license document, but changing it is not allowed. Preamble The licenses for most software are designed to take away your freedom to share and change it. By contrast, the GNU General Public License is intended to guarantee your freedom to share and change free software--to make sure the software is free for all its users. This General Public License applies to most of the Free Software Foundation's software and to any other program whose authors commit to using it. (Some other Free Software Foundation software is covered by the GNU Library General Public License instead.) You can apply it to your programs, too. When we speak of free software, we are referring to freedom, not price. Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge for this service if you wish), that you receive source code or can get it if you want it, that you can change the software or use pieces of it in new free programs; and that you know you can do these things. To protect your rights, we need to make restrictions that forbid anyone to deny you these rights or to ask you to surrender the rights. These restrictions translate to certain responsibilities for you if you distribute copies of the software, or if you modify it. For example, if you distribute copies of such a program, whether gratis or for a fee, you must give the recipients all the rights that you have. You must make sure that they, too, receive or can get the source code. And you must show them these terms so they know their rights. We protect your rights with two steps: (1) copyright the software, and (2) offer you this license which gives you legal permission to copy, distribute and/or modify the software. Also, for each author's protection and ours, we want to make certain that everyone understands that there is no warranty for this free software. If the software is modified by someone else and passed on, we want its recipients to know that what they have is not the original, so that any problems introduced by others will not reflect on the original authors' reputations. Finally, any free program is threatened constantly by software patents. We wish to avoid the danger that redistributors of a free program will individually obtain patent licenses, in effect making the program proprietary. To prevent this, we have made it clear that any patent must be licensed for everyone's free use or not licensed at all. The precise terms and conditions for copying, distribution and modification follow. GNU GENERAL PUBLIC LICENSE TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION 0. This License applies to any program or other work which contains a notice placed by the copyright holder saying it may be distributed under the terms of this General Public License. The "Program", below, refers to any such program or work, and a "work based on the Program" means either the Program or any derivative work under copyright law: that is to say, a work containing the Program or a portion of it, either verbatim or with modifications and/or translated into another language. (Hereinafter, translation is included without limitation in the term "modification".) Each licensee is addressed as "you". Activities other than copying, distribution and modification are not covered by this License; they are outside its scope. The act of running the Program is not restricted, and the output from the Program is covered only if its contents constitute a work based on the Program (independent of having been made by running the Program). Whether that is true depends on what the Program does. 1. You may copy and distribute verbatim copies of the Program's source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice and disclaimer of warranty; keep intact all the notices that refer to this License and to the absence of any warranty; and give any other recipients of the Program a copy of this License along with the Program. You may charge a fee for the physical act of transferring a copy, and you may at your option offer warranty protection in exchange for a fee. 2. You may modify your copy or copies of the Program or any portion of it, thus forming a work based on the Program, and copy and distribute such modifications or work under the terms of Section 1 above, provided that you also meet all of these conditions: a) You must cause the modified files to carry prominent notices stating that you changed the files and the date of any change. b) You must cause any work that you distribute or publish, that in whole or in part contains or is derived from the Program or any part thereof, to be licensed as a whole at no charge to all third parties under the terms of this License. c) If the modified program normally reads commands interactively when run, you must cause it, when started running for such interactive use in the most ordinary way, to print or display an announcement including an appropriate copyright notice and a notice that there is no warranty (or else, saying that you provide a warranty) and that users may redistribute the program under these conditions, and telling the user how to view a copy of this License. (Exception: if the Program itself is interactive but does not normally print such an announcement, your work based on the Program is not required to print an announcement.) These requirements apply to the modified work as a whole. If identifiable sections of that work are not derived from the Program, and can be reasonably considered independent and separate works in themselves, then this License, and its terms, do not apply to those sections when you distribute them as separate works. But when you distribute the same sections as part of a whole which is a work based on the Program, the distribution of the whole must be on the terms of this License, whose permissions for other licensees extend to the entire whole, and thus to each and every part regardless of who wrote it. Thus, it is not the intent of this section to claim rights or contest your rights to work written entirely by you; rather, the intent is to exercise the right to control the distribution of derivative or collective works based on the Program. In addition, mere aggregation of another work not based on the Program with the Program (or with a work based on the Program) on a volume of a storage or distribution medium does not bring the other work under the scope of this License. 3. You may copy and distribute the Program (or a work based on it, under Section 2) in object code or executable form under the terms of Sections 1 and 2 above provided that you also do one of the following: a) Accompany it with the complete corresponding machine-readable source code, which must be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or, b) Accompany it with a written offer, valid for at least three years, to give any third party, for a charge no more than your cost of physically performing source distribution, a complete machine-readable copy of the corresponding source code, to be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or, c) Accompany it with the information you received as to the offer to distribute corresponding source code. (This alternative is allowed only for noncommercial distribution and only if you received the program in object code or executable form with such an offer, in accord with Subsection b above.) The source code for a work means the preferred form of the work for making modifications to it. For an executable work, complete source code means all the source code for all modules it contains, plus any associated interface definition files, plus the scripts used to control compilation and installation of the executable. However, as a special exception, the source code distributed need not include anything that is normally distributed (in either source or binary form) with the major components (compiler, kernel, and so on) of the operating system on which the executable runs, unless that component itself accompanies the executable. If distribution of executable or object code is made by offering access to copy from a designated place, then offering equivalent access to copy the source code from the same place counts as distribution of the source code, even though third parties are not compelled to copy the source along with the object code. 4. You may not copy, modify, sublicense, or distribute the Program except as expressly provided under this License. Any attempt otherwise to copy, modify, sublicense or distribute the Program is void, and will automatically terminate your rights under this License. However, parties who have received copies, or rights, from you under this License will not have their licenses terminated so long as such parties remain in full compliance. 5. You are not required to accept this License, since you have not signed it. However, nothing else grants you permission to modify or distribute the Program or its derivative works. These actions are prohibited by law if you do not accept this License. Therefore, by modifying or distributing the Program (or any work based on the Program), you indicate your acceptance of this License to do so, and all its terms and conditions for copying, distributing or modifying the Program or works based on it. 6. Each time you redistribute the Program (or any work based on the Program), the recipient automatically receives a license from the original licensor to copy, distribute or modify the Program subject to these terms and conditions. You may not impose any further restrictions on the recipients' exercise of the rights granted herein. You are not responsible for enforcing compliance by third parties to this License. 7. If, as a consequence of a court judgment or allegation of patent infringement or for any other reason (not limited to patent issues), conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of this License, they do not excuse you from the conditions of this License. If you cannot distribute so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not distribute the Program at all. For example, if a patent license would not permit royalty-free redistribution of the Program by all those who receive copies directly or indirectly through you, then the only way you could satisfy both it and this License would be to refrain entirely from distribution of the Program. If any portion of this section is held invalid or unenforceable under any particular circumstance, the balance of the section is intended to apply and the section as a whole is intended to apply in other circumstances. It is not the purpose of this section to induce you to infringe any patents or other property right claims or to contest validity of any such claims; this section has the sole purpose of protecting the integrity of the free software distribution system, which is implemented by public license practices. Many people have made generous contributions to the wide range of software distributed through that system in reliance on consistent application of that system; it is up to the author/donor to decide if he or she is willing to distribute software through any other system and a licensee cannot impose that choice. This section is intended to make thoroughly clear what is believed to be a consequence of the rest of this License. 8. If the distribution and/or use of the Program is restricted in certain countries either by patents or by copyrighted interfaces, the original copyright holder who places the Program under this License may add an explicit geographical distribution limitation excluding those countries, so that distribution is permitted only in or among countries not thus excluded. In such case, this License incorporates the limitation as if written in the body of this License. 9. The Free Software Foundation may publish revised and/or new versions of the General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns. Each version is given a distinguishing version number. If the Program specifies a version number of this License which applies to it and "any later version", you have the option of following the terms and conditions either of that version or of any later version published by the Free Software Foundation. If the Program does not specify a version number of this License, you may choose any version ever published by the Free Software Foundation. 10. If you wish to incorporate parts of the Program into other free programs whose distribution conditions are different, write to the author to ask for permission. For software which is copyrighted by the Free Software Foundation, write to the Free Software Foundation; we sometimes make exceptions for this. Our decision will be guided by the two goals of preserving the free status of all derivatives of our free software and of promoting the sharing and reuse of software generally. NO WARRANTY 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. END OF TERMS AND CONDITIONS ---------------------------------------------------------------------------- The Artistic License Preamble The intent of this document is to state the conditions under which a Package may be copied, such that the Copyright Holder maintains some semblance of artistic control over the development of the package, while giving the users of the package the right to use and distribute the Package in a more-or-less customary fashion, plus the right to make reasonable modifications. Definitions: - "Package" refers to the collection of files distributed by the Copyright Holder, and derivatives of that collection of files created through textual modification. - "Standard Version" refers to such a Package if it has not been modified, or has been modified in accordance with the wishes of the Copyright Holder. - "Copyright Holder" is whoever is named in the copyright or copyrights for the package. - "You" is you, if you're thinking about copying or distributing this Package. - "Reasonable copying fee" is whatever you can justify on the basis of media cost, duplication charges, time of people involved, and so on. (You will not be required to justify it to the Copyright Holder, but only to the computing community at large as a market that must bear the fee.) - "Freely Available" means that no fee is charged for the item itself, though there may be fees involved in handling the item. It also means that recipients of the item may redistribute it under the same conditions they received it. 1. You may make and give away verbatim copies of the source form of the Standard Version of this Package without restriction, provided that you duplicate all of the original copyright notices and associated disclaimers. 2. You may apply bug fixes, portability fixes and other modifications derived from the Public Domain or from the Copyright Holder. A Package modified in such a way shall still be considered the Standard Version. 3. You may otherwise modify your copy of this Package in any way, provided that you insert a prominent notice in each changed file stating how and when you changed that file, and provided that you do at least ONE of the following: a) place your modifications in the Public Domain or otherwise make them Freely Available, such as by posting said modifications to Usenet or an equivalent medium, or placing the modifications on a major archive site such as ftp.uu.net, or by allowing the Copyright Holder to include your modifications in the Standard Version of the Package. b) use the modified Package only within your corporation or organization. c) rename any non-standard executables so the names do not conflict with standard executables, which must also be provided, and provide a separate manual page for each non-standard executable that clearly documents how it differs from the Standard Version. d) make other distribution arrangements with the Copyright Holder. 4. You may distribute the programs of this Package in object code or executable form, provided that you do at least ONE of the following: a) distribute a Standard Version of the executables and library files, together with instructions (in the manual page or equivalent) on where to get the Standard Version. b) accompany the distribution with the machine-readable source of the Package with your modifications. c) accompany any non-standard executables with their corresponding Standard Version executables, giving the non-standard executables non-standard names, and clearly documenting the differences in manual pages (or equivalent), together with instructions on where to get the Standard Version. d) make other distribution arrangements with the Copyright Holder. 5. You may charge a reasonable copying fee for any distribution of this Package. You may charge any fee you choose for support of this Package. You may not charge a fee for this Package itself. However, you may distribute this Package in aggregate with other (possibly commercial) programs as part of a larger (possibly commercial) software distribution provided that you do not advertise this Package as a product of your own. 6. The scripts and library files supplied as input to or produced as output from the programs of this Package do not automatically fall under the copyright of this Package, but belong to whomever generated them, and may be sold commercially, and may be aggregated with this Package. 7. C or perl subroutines supplied by you and linked into this Package shall not be considered part of this Package. 8.

This hopefully resolved #47223 (ADAMK) 1.28 Tue 16 Jun 2009 - Adam Kennedy - Changing to production version for release - Reverted to revision 4736 and converted `External File Attribute' values for symbolic links to hexadecimal (HAGGAI) - Fixed: #15026: AddTree does not include files with german umlauts in the filename (HAGGAI) - Switched from Compress::Zlib to Compress::Raw::Zlib (AGRUNDMA) - Moved crc32 from bin to script (ADAMK) 1.27_01 Tue 16 Dec 2008 - Adam Kennedy - Makefile.PL will create a better META.yml - This is a test release for various improvements provided by Alan Haggai. The entire release is credited to his grant work. - Fixed #25726: extractMembers failing across fork on Windows. - Fixed #12493: Can't add new files to archives which contain files named 0,1,2,3,4,5,6,7,8,9 with no extension. (Files named "0" are not archived) - Fixed #22933: Properly extract symbolic links. - Fixed #20246: Ability to assign a compression level to addTree calls. - Corrected regular expression for stripping trailing / - Corrected addFileOrDirectory() behaviour and cleaned up some code - Added symbolic link support to addFileOrDirectory - Fixed #34657: No option, undefined behavior zipping symbolic links (symlinks) - Added storeSymbolicLink() - Fixed bitFlag() to set General Pupose Bit Flags 1.26 Mon 13 Oct 2008 - Adam Kennedy - Fixed the dreaded but #24036: WinXP Explorer Exposes Problems. This caused directories to appear as files in Windows Explorer and was caused by Windows always reading the msdos directory bit even when the file attributes are types as unix. Resolved by emulating the behaviour of Info-Zip and setting the 5th bit in the externalFileAttributes field. 1.25 Sat 11 Oct 2008 - Adam Kennedy - Removing "use warnings" instances that somehow slipped in - Skip test if Digest::MD5 is not available 1.24 Sun 23 Aug 2008 - Adam Kennedy - Blatantly pander to CPANTS by adding use strict to a deprecated module - Add an explicit load of FileHandle since in some circumstances, calling GLOB->print() failed. - Fixed http://rt.cpan.org/Public/Bug/Display.html?id=25925 : - Archive-Zip wrote faulty .zip files when $\ was set (such as when running using perl -l). - Incorporated a heavily modified version of ECARROLL's test file. - Thanks for ECARROLL for reporting it, and helping with the investigation. - The fix was to convert all $fh->print(@data) to $self->_print($fh, @data) where the _print() method localizes $\ to undef. - Fixed http://rt.cpan.org/Ticket/Display.html?id=14132 : - Incorrect file permissions after extraction. - Archive-Zip did not set the file permissions correctly in extractToFileNamed(). - Added t/10_chmod.t and t/data/chmod.zip. Changed lib/Archive/Zip/Member.pm. - Reported by ak2 and jlv (Thanks!) - SHLOMIF wrote the test script. - (SHLOMIF) - Removed a double "required module" from the Archive::Zip POD. - Fixed http://rt.cpan.org/Ticket/Display.html?id=24557 ("documentation improvement"): - mentioned Archive::Zip::MemberRead in a few places. - TODO: - 1. Add a method to Archive::Zip to get a ::MemberRead from an archive member using -> notation. (?) - 2. In the POD of ::MemberRead - replace the indirect object call. - Changed the POD of ::MemberRead: - replaced the indirect object construction with $PKG->new(). - Fixed http://rt.cpan.org/Public/Bug/Display.html?id=34103 : - changed the example to read unless ( .. == AZ_OK) instead of unless ( != AZ_OK), which was incorrect. 1.23 Thu 8 Nov 2007 - Adam Kennedy - Temporarily skilling some failing tests on Win32 in the interests of toolchain sanity. (until we work out the real problem here) 1.22 Fri 2 Nov 2007 - Adam Kennedy - Fixing platform compatibility bugs in the new regression tests from 1.21. 1.21 Thu 1 Nov 2007 - Adam Kennedy - Tidying up copyright formatting a bit. - Disable the GPBF_HAS_DATA_DESCRIPTOR_MASK bit when auto-switching directory storage to STORED because of a WinZip workaround because the read code in Java JAR which was... ok, I really don't understand, but Roland from Verisign says this one extra line unbreaks JAR files, so I just applied it :) - fixed http://rt.cpan.org/Public/Bug/Display.html?id=27463 with a regression test - cannot add files whose entire filenames are "0". (SHLOMIF). - fixed http://rt.cpan.org/Public/Bug/Display.html?id=26384 with a regression test - Archive::Zip::MemberRead::getline ignores $INPUT_RECORD_SEPARATOR . The modified file in the bug had it to be reworked a bit and tests were added in the file 08_readmember_record_sep.t. - Thanks to kovesp [...] sympatico.ca - (SHLOMIF) 1.20 Tue 5 Jun 2007 - Adam Kennedy - Removing dependency on File::Which due to public outburst of flaming on cpanra(n)tings by H.Merijn Brand. Try a simple email next time. :( - Embedding an entire copy of File::Which inside the tests instead as an alternative to compensating for the lack of build_requires. - Removing the docs directory. It only had out of date files and non-free copyrighted materials. The tarball was probably illegal to distribute as a result. (reported by Debian devs) 1.19 Internal use, public release skipped 1.18 Wed 25 Oct 2006 - Adam Kennedy - Changing to a production version for final release - No other changes of any kind 1.17_05 Tue 19 Sep 2006 - Adam Kennedy - Seperated the classes from the main file into seperate packages. - Merged the Zip.pod into the main Zip.pm file. - Applied default Perl::Tidy to all of the source files, to improve the readability and maintainability of the files. - Added license in Makefile.PL - Added some additional entries to the realclean files 1.17_03 Sat 16 Sep 2006 - Adam Kennedy - Adding dependency on File::Which to deal with problems on systems that lack zip and unzip programs. This really should be a build-time dependency only, but ExtUtils::MakeMaker lacks that capability. - Builds and tests cleanly on Win32 now. 1.17_02 Sun 7 May 2006 - Adam Kennedy - Renamed the test scripts to the more conventional 01_name.t style - Upgraded all test scripts from Test.pm to Test::More (removing Test.pm dependency) - Various other miscellaneous cleanups of the test scripts - Removed MANIFEST and pod.t from repository (will be auto-generated) - Some cleaning up of the POD documentation for readability - Added SUPPORT section to docs - Merged external TODO file into the POD as a more-common TO DO section - Added a BUGS section to the docs 1.17_01 Sun 30 Apr 2006 - Adam Kennedy - Imported Archive::Zip into http://svn.ali.as/cpan/ orphanage. If you have a CPAN login and have released a module, ask ADAMK about an account and you can repair your bug directly in the repository. - Removed the revision comments from the old CVS repository - DOS DateTime Format doesn't support dates before 1980 and goes crazy when decoding back to unix time. If we don't get passed a time at all (0 or undef) we now throw an error. - DOS DateTime Format doesn't support dates before 1980, so if we find any we warn and use Jan 1 12:01pm 1980 if we encounter any - Win32 doesn't support directory modification times. Tentatively use the current time as the mod-time to prevent sending null times to the unix2dos converter (and the resulting error) - Reformat the expected empty zip warning in the output to add a note that the warning is entirely normal. Would be nice if some time later we can suppress it altogether, but I don't have the cross-platform STDERR-fu without adding a dependency to IPC::Run3 (which would be bad). - Adding a proper $VERSION to all classes, and synchronising them to the same value. - Adding a BEGIN block around the require 5.003_96 so it works at compile-time instead of post-compile. - Moved crc32 to bin/crc32 in line with package layout conventions 1.16 Mon Jul 04 12:49:30 CDT 2005 - Grrrr...removed test that fails when installing under CPANPLUS. 1.15 Wed Jun 22 10:24:25 CDT 2005 - added fix for RT #12771 Minor nit: warning in Archive::Zip::DirectoryMember::contents() - added fix for RT #13327 Formatting problem in Archive::Zip::Tree manpage 1.15_02 Sat Mar 12 09:16:30 CST 2005 - fixed dates in previous entry! - began the process of migrating from the monolithic t/test.t to smaller scripts using Test::More. - started work on improving Archive::Zip's test coverage. Coverage is now up to just over 80%. - added error handling to writeToFileHandle - fixed small bug in extractMember from previous version 1.15_01 Wed Mar 9 22:26:52 CST 2005 - added fix for RT #11818 extractMember method corrupts archive - added t/pod.t to test for pod correctness 1.10 Thu Mar 25 06:24:17 PST 2004 - Fixed documentation of setErrorHandler() - Fixed link to Japanese translation of docs - Added Compress::Zlib Bufsize patch from Yeasah Pell that was supposed to have been added in 1.02 - Fixed problems with backup filenames for zips with no extension - Fixed problems with undef volume names in _asLocalName() 1.09 Wed Nov 26 17:43:49 PST 2003 - Fixed handling of inserted garbage (as from viruses) - Always check for local header signatures before using them - Added updateMember() and updateTree() functions - Added examples/mailZip.pl - Added examples/updateTree.pl - Fixed some potential but unreported bugs with function parameters like '0' - Removed stray warn() call - Caught undef second arg to replaceMember() - Fixed test suite run with spaces in build dir name (ticket 4214) 1.08 Tue Oct 21 07:01:29 PDT 2003 - test noise fix from Michael Schwern (ticket 4174) - FAQ NAME fix from Michael Schwern (ticket 4175) 1.07 Mon Oct 20 06:48:41 PDT 2003 - Added file attribute code by Maurice Aubrey - Added FAQ about RedHat 9 - Added check for empty filenames 1.06 Thu Jul 17 11:06:18 PDT 2003 - Fixed seek use with IO::Scalar and IO::String - Fixed use of binmode with pseudo-file handles - Removed qr{} form for older Perl versions - Changed rel2abs logic in _asLocalName() if there is a volume - Fixed errors with making directories in extractMember() when none provided - Return AZ_OK in extractMemberWithoutPaths() if member is a directory - Fixed problem in extractTree with blank directory becoming "." prefix - Added examples/writeScalar2.pl to show how to use IO::String as destination of Zip write - Edited docs and FAQ to recommend against using absolute path names in zip files. 1.05 Wed Sep 11 12:31:20 PDT 2002 - fixed untaint from 1.04 1.04 Wed Sep 11 07:22:04 PDT 2002 - added untaint of lastModFileDateTime 1.03 Mon Sep 2 20:42:43 PDT 2002 - Removed dependency on IO::Scalar - Set required version of File::Spec to 0.8 - Removed tests of examples that needed IO::Scalar - Added binmode() call to read/writeScalar examples - Fixed addTree() for 5.005 compatibility (still untested with 5.004) - Fixed mkdir() calls for 5.005 - Clarified documentation of tree operations 1.02 Fri Aug 23 17:07:22 PDT 2002 - Many changes for cross-platform use (use File::Spec everywhere) - Separated POD from Perl - Moved Archive::Zip::Tree contents into Archive::Zip A::Z::Tree is now deprecated and will warn with -w - Reorganized docs - Added FAQ - Added chunkSize() call to report current chunk size and added C::Z BufSize patch from Yeasah Pell. - Added fileName() to report last read zip file name - Added capability to prepend data, like for SFX files - Added examples/selfex.pl for self-extracting archives creation - Added examples/zipcheck.pl for validity testing - Made extractToFileNamed() set access/modification times - Added t/testTree.t to test A::Z::Tree - Fix/speed up memberNamed() - Added Archive::Zip::MemberRead by Sreeji K.

SYNOPSIS # Create a Zip file use Archive::Zip qw( :ERROR_CODES :CONSTANTS ); my $zip = Archive::Zip->new(); # Add a directory my $dir_member = $zip->addDirectory( 'dirname/' ); # Add a file from a string with compression my $string_member = $zip->addString( 'This is a test', 'stringMember.txt' ); $string_member->desiredCompressionMethod( COMPRESSION_DEFLATED ); # Add a file from disk my $file_member = $zip->addFile( 'xyz.pl', 'AnotherName.pl' ); # Save the Zip file unless ( $zip->writeToFileNamed('someZip.zip') == AZ_OK ) { die 'write error'; } # Read a Zip file my $somezip = Archive::Zip->new(); unless ( $somezip->read( 'someZip.zip' ) == AZ_OK ) { die 'read error'; } # Change the compression type for a file in the Zip my $member = $somezip->memberNamed( 'stringMember.txt' ); $member->desiredCompressionMethod( COMPRESSION_STORED ); unless ( $zip->writeToFileNamed( 'someOtherZip.zip' ) == AZ_OK ) { die 'write error'; } DESCRIPTION The Archive::Zip module allows a Perl program to create, manipulate, read, and write Zip archive files. Zip archives can be created, or you can read from existing zip files. Once created, they can be written to files, streams, or strings. Members can be added, removed, extracted, replaced, rearranged, and enumerated. They can also be renamed or have their dates, comments, or other attributes queried or modified. Their data can be compressed or uncompressed as needed. Members can be created from members in existing Zip files, or from existing directories, files, or strings. This module uses the Compress::Raw::Zlib library to read and write the compressed streams inside the files. One can use Archive::Zip::MemberRead to read the zip file archive members as if they were files. File Naming Regardless of what your local file system uses for file naming, names in a Zip file are in Unix format (*forward* slashes (/) separating directory names, etc.). "Archive::Zip" tries to be consistent with file naming conventions, and will translate back and forth between native and Zip file names. However, it can't guess which format names are in. So two rules control what kind of file name you must pass various routines: Names of files are in local format. "File::Spec" and "File::Basename" are used for various file operations. When you're referring to a file on your system, use its file naming conventions. Names of archive members are in Unix format. This applies to every method that refers to an archive member, or provides a name for new archive members. The "extract()" methods that can take one or two names will convert from local to zip names if you call them with a single name. Archive::Zip Object Model Overview Archive::Zip::Archive objects are what you ordinarily deal with. These maintain the structure of a zip file, without necessarily holding data. When a zip is read from a disk file, the (possibly compressed) data still lives in the file, not in memory. Archive members hold information about the individual members, but not (usually) the actual member data. When the zip is written to a (different) file, the member data is compressed or copied as needed. It is possible to make archive members whose data is held in a string in memory, but this is not done when a zip file is read. Directory members don't have any data. Inheritance Exporter Archive::Zip Common base class, has defs. Archive::Zip::Archive A Zip archive. Archive::Zip::Member Abstract superclass for all members. Archive::Zip::StringMember Member made from a string Archive::Zip::FileMember Member made from an external file Archive::Zip::ZipFileMember Member that lives in a zip file Archive::Zip::NewFileMember Member whose data is in a file Archive::Zip::DirectoryMember Member that is a directory EXPORTS :CONSTANTS Exports the following constants: FA_MSDOS FA_UNIX GPBF_ENCRYPTED_MASK GPBF_DEFLATING_COMPRESSION_MASK GPBF_HAS_DATA_DESCRIPTOR_MASK COMPRESSION_STORED COMPRESSION_DEFLATED IFA_TEXT_FILE_MASK IFA_TEXT_FILE IFA_BINARY_FILE COMPRESSION_LEVEL_NONE COMPRESSION_LEVEL_DEFAULT COMPRESSION_LEVEL_FASTEST COMPRESSION_LEVEL_BEST_COMPRESSION :MISC_CONSTANTS Exports the following constants (only necessary for extending the module): FA_AMIGA FA_VAX_VMS FA_VM_CMS FA_ATARI_ST FA_OS2_HPFS FA_MACINTOSH FA_Z_SYSTEM FA_CPM FA_WINDOWS_NTFS GPBF_IMPLODING_8K_SLIDING_DICTIONARY_MASK GPBF_IMPLODING_3_SHANNON_FANO_TREES_MASK GPBF_IS_COMPRESSED_PATCHED_DATA_MASK COMPRESSION_SHRUNK DEFLATING_COMPRESSION_NORMAL DEFLATING_COMPRESSION_MAXIMUM DEFLATING_COMPRESSION_FAST DEFLATING_COMPRESSION_SUPER_FAST COMPRESSION_REDUCED_1 COMPRESSION_REDUCED_2 COMPRESSION_REDUCED_3 COMPRESSION_REDUCED_4 COMPRESSION_IMPLODED COMPRESSION_TOKENIZED COMPRESSION_DEFLATED_ENHANCED COMPRESSION_PKWARE_DATA_COMPRESSION_LIBRARY_IMPLODED :ERROR_CODES Explained below. Returned from most methods. AZ_OK AZ_STREAM_END AZ_ERROR AZ_FORMAT_ERROR AZ_IO_ERROR ERROR CODES Many of the methods in Archive::Zip return error codes. These are implemented as inline subroutines, using the "use constant" pragma. They can be imported into your namespace using the ":ERROR_CODES" tag: use Archive::Zip qw( :ERROR_CODES ); ... unless ( $zip->read( 'myfile.zip' ) == AZ_OK ) { die "whoops!"; } AZ_OK (0) Everything is fine. AZ_STREAM_END (1) The read stream (or central directory) ended normally. AZ_ERROR (2) There was some generic kind of error. AZ_FORMAT_ERROR (3) There is a format error in a ZIP file being read. AZ_IO_ERROR (4) There was an IO error. Compression Archive::Zip allows each member of a ZIP file to be compressed (using the Deflate algorithm) or uncompressed. Other compression algorithms that some versions of ZIP have been able to produce are not supported. Each member has two compression methods: the one it's stored as (this is always COMPRESSION_STORED for string and external file members), and the one you desire for the member in the zip file. These can be different, of course, so you can make a zip member that is not compressed out of one that is, and vice versa. You can inquire about the current compression and set the desired compression method: my $member = $zip->memberNamed( 'xyz.txt' ); $member->compressionMethod(); # return current compression # set to read uncompressed $member->desiredCompressionMethod( COMPRESSION_STORED ); # set to read compressed $member->desiredCompressionMethod( COMPRESSION_DEFLATED ); There are two different compression methods: COMPRESSION_STORED File is stored (no compression) COMPRESSION_DEFLATED File is Deflated Compression Levels If a member's desiredCompressionMethod is COMPRESSION_DEFLATED, you can choose different compression levels. This choice may affect the speed of compression and decompression, as well as the size of the compressed member data. $member->desiredCompressionLevel( 9 ); The levels given can be: * 0 or COMPRESSION_LEVEL_NONE This is the same as saying $member->desiredCompressionMethod( COMPRESSION_STORED ); * 1 .. 9 1 gives the best speed and worst compression, and 9 gives the best compression and worst speed. * COMPRESSION_LEVEL_FASTEST This is a synonym for level 1. * COMPRESSION_LEVEL_BEST_COMPRESSION This is a synonym for level 9. * COMPRESSION_LEVEL_DEFAULT This gives a good compromise between speed and compression, and is currently equivalent to 6 (this is in the zlib code). This is the level that will be used if not specified. Archive::Zip Methods The Archive::Zip class (and its invisible subclass Archive::Zip::Archive) implement generic zip file functionality. Creating a new Archive::Zip object actually makes an Archive::Zip::Archive object, but you don't have to worry about this unless you're subclassing. Constructor new( [$fileName] ) new( { filename => $fileName } ) Make a new, empty zip archive. my $zip = Archive::Zip->new(); If an additional argument is passed, new() will call read() to read the contents of an archive: my $zip = Archive::Zip->new( 'xyz.zip' ); If a filename argument is passed and the read fails for any reason, new will return undef. For this reason, it may be better to call read separately. Zip Archive Utility Methods These Archive::Zip methods may be called as functions or as object methods. Do not call them as class methods: $zip = Archive::Zip->new(); $crc = Archive::Zip::computeCRC32( 'ghijkl' ); # OK $crc = $zip->computeCRC32( 'ghijkl' ); # also OK $crc = Archive::Zip->computeCRC32( 'ghijkl' ); # NOT OK Archive::Zip::computeCRC32( $string [, $crc] ) Archive::Zip::computeCRC32( { string => $string [, checksum => $crc ] } ) This is a utility function that uses the Compress::Raw::Zlib CRC routine to compute a CRC-32. You can get the CRC of a string: $crc = Archive::Zip::computeCRC32( $string ); Or you can compute the running CRC: $crc = 0; $crc = Archive::Zip::computeCRC32( 'abcdef', $crc ); $crc = Archive::Zip::computeCRC32( 'ghijkl', $crc ); Archive::Zip::setChunkSize( $number ) Archive::Zip::setChunkSize( { chunkSize => $number } ) Report or change chunk size used for reading and writing. This can make big differences in dealing with large files. Currently, this defaults to 32K. This also changes the chunk size used for Compress::Raw::Zlib. You must call setChunkSize() before reading or writing. This is not exportable, so you must call it like: Archive::Zip::setChunkSize( 4096 ); or as a method on a zip (though this is a global setting). Returns old chunk size. Archive::Zip::chunkSize() Returns the current chunk size: my $chunkSize = Archive::Zip::chunkSize(); Archive::Zip::setErrorHandler( \&subroutine ) Archive::Zip::setErrorHandler( { subroutine => \&subroutine } ) Change the subroutine called with error strings. This defaults to \&Carp::carp, but you may want to change it to get the error strings. This is not exportable, so you must call it like: Archive::Zip::setErrorHandler( \&myErrorHandler ); If myErrorHandler is undef, resets handler to default. Returns old error handler. Note that if you call Carp::carp or a similar routine or if you're chaining to the default error handler from your error handler, you may want to increment the number of caller levels that are skipped (do not just set it to a number): $Carp::CarpLevel++; Archive::Zip::tempFile( [ $tmpdir ] ) Archive::Zip::tempFile( { tempDir => $tmpdir } ) Create a uniquely named temp file. It will be returned open for read/write. If $tmpdir is given, it is used as the name of a directory to create the file in. If not given, creates the file using "File::Spec::tmpdir()". Generally, you can override this choice using the $ENV{TMPDIR} environment variable. But see the File::Spec documentation for your system. Note that on many systems, if you're running in taint mode, then you must make sure that $ENV{TMPDIR} is untainted for it to be used. Will *NOT* create $tmpdir if it does not exist (this is a change from prior versions!). Returns file handle and name: my ($fh, $name) = Archive::Zip::tempFile(); my ($fh, $name) = Archive::Zip::tempFile('myTempDir'); my $fh = Archive::Zip::tempFile(); # if you don't need the name Zip Archive Accessors members() Return a copy of the members array my @members = $zip->members(); numberOfMembers() Return the number of members I have memberNames() Return a list of the (internal) file names of the zip members memberNamed( $string ) memberNamed( { zipName => $string } ) Return ref to member whose filename equals given filename or undef. $string must be in Zip (Unix) filename format. membersMatching( $regex ) membersMatching( { regex => $regex } ) Return array of members whose filenames match given regular expression in list context. Returns number of matching members in scalar context. my @textFileMembers = $zip->membersMatching( '.*\.txt' ); # or my $numberOfTextFiles = $zip->membersMatching( '.*\.txt' ); diskNumber() Return the disk that I start on. Not used for writing zips, but might be interesting if you read a zip in. This should be 0, as Archive::Zip does not handle multi-volume archives. diskNumberWithStartOfCentralDirectory() Return the disk number that holds the beginning of the central directory. Not used for writing zips, but might be interesting if you read a zip in. This should be 0, as Archive::Zip does not handle multi-volume archives. numberOfCentralDirectoriesOnThisDisk() Return the number of CD structures in the zipfile last read in. Not used for writing zips, but might be interesting if you read a zip in. numberOfCentralDirectories() Return the number of CD structures in the zipfile last read in. Not used for writing zips, but might be interesting if you read a zip in. centralDirectorySize() Returns central directory size, as read from an external zip file. Not used for writing zips, but might be interesting if you read a zip in. centralDirectoryOffsetWRTStartingDiskNumber() Returns the offset into the zip file where the CD begins. Not used for writing zips, but might be interesting if you read a zip in. zipfileComment( [ $string ] ) zipfileComment( [ { comment => $string } ] ) Get or set the zipfile comment. Returns the old comment. print $zip->zipfileComment(); $zip->zipfileComment( 'New Comment' ); eocdOffset() Returns the (unexpected) number of bytes between where the EOCD was found and where it expected to be. This is normally 0, but would be positive if something (a virus, perhaps) had added bytes somewhere before the EOCD. Not used for writing zips, but might be interesting if you read a zip in. Here is an example of how you can diagnose this: my $zip = Archive::Zip->new('somefile.zip'); if ($zip->eocdOffset()) { warn "A virus has added ", $zip->eocdOffset, " bytes of garbage\n"; } The "eocdOffset()" is used to adjust the starting position of member headers, if necessary. fileName() Returns the name of the file last read from. If nothing has been read yet, returns an empty string; if read from a file handle, returns the handle in string form. Zip Archive Member Operations Various operations on a zip file modify members. When a member is passed as an argument, you can either use a reference to the member itself, or the name of a member. Of course, using the name requires that names be unique within a zip (this is not enforced). removeMember( $memberOrName ) removeMember( { memberOrZipName => $memberOrName } ) Remove and return the given member, or match its name and remove it. Returns undef if member or name does not exist in this Zip. No-op if member does not belong to this zip. replaceMember( $memberOrName, $newMember ) replaceMember( { memberOrZipName => $memberOrName, newMember => $newMember } ) Remove and return the given member, or match its name and remove it. Replace with new member. Returns undef if member or name does not exist in this Zip, or if $newMember is undefined. It is an (undiagnosed) error to provide a $newMember that is a member of the zip being modified. my $member1 = $zip->removeMember( 'xyz' ); my $member2 = $zip->replaceMember( 'abc', $member1 ); # now, $member2 (named 'abc') is not in $zip, # and $member1 (named 'xyz') is, having taken $member2's place. extractMember( $memberOrName [, $extractedName ] ) extractMember( { memberOrZipName => $memberOrName [, name => $extractedName ] } ) Extract the given member, or match its name and extract it. Returns undef if member does not exist in this Zip. If optional second arg is given, use it as the name of the extracted member. Otherwise, the internal filename of the member is used as the name of the extracted file or directory. If you pass $extractedName, it should be in the local file system's format. All necessary directories will be created. Returns "AZ_OK" on success. extractMemberWithoutPaths( $memberOrName [, $extractedName ] ) extractMemberWithoutPaths( { memberOrZipName => $memberOrName [, name => $extractedName ] } ) Extract the given member, or match its name and extract it. Does not use path information (extracts into the current directory). Returns undef if member does not exist in this Zip. If optional second arg is given, use it as the name of the extracted member (its paths will be deleted too). Otherwise, the internal filename of the member (minus paths) is used as the name of the extracted file or directory. Returns "AZ_OK" on success. addMember( $member ) addMember( { member => $member } ) Append a member (possibly from another zip file) to the zip file. Returns the new member. Generally, you will use addFile(), addDirectory(), addFileOrDirectory(), addString(), or read() to add members. # Move member named 'abc' to end of zip: my $member = $zip->removeMember( 'abc' ); $zip->addMember( $member ); updateMember( $memberOrName, $fileName ) updateMember( { memberOrZipName => $memberOrName, name => $fileName } ) Update a single member from the file or directory named $fileName. Returns the (possibly added or updated) member, if any; "undef" on errors. The comparison is based on "lastModTime()" and (in the case of a non-directory) the size of the file. addFile( $fileName [, $newName, $compressionLevel ] ) addFile( { filename => $fileName [, zipName => $newName, compressionLevel => $compressionLevel } ] ) Append a member whose data comes from an external file, returning the member or undef. The member will have its file name set to the name of the external file, and its desiredCompressionMethod set to COMPRESSION_DEFLATED. The file attributes and last modification time will be set from the file. If the name given does not represent a readable plain file or symbolic link, undef will be returned. $fileName must be in the format required for the local file system. The optional $newName argument sets the internal file name to something different than the given $fileName. $newName, if given, must be in Zip name format (i.e. Unix). The text mode bit will be set if the contents appears to be text (as returned by the "-T" perl operator). *NOTE* that you should not (generally) use absolute path names in zip member names, as this will cause problems with some zip tools as well as introduce a security hole and make the zip harder to use. addDirectory( $directoryName [, $fileName ] ) addDirectory( { directoryName => $directoryName [, zipName => $fileName ] } ) Append a member created from the given directory name. The directory name does not have to name an existing directory. If the named directory exists, the file modification time and permissions are set from the existing directory, otherwise they are set to now and permissive default permissions. $directoryName must be in local file system format. The optional second argument sets the name of the archive member (which defaults to $directoryName). If given, it must be in Zip (Unix) format. Returns the new member. addFileOrDirectory( $name [, $newName, $compressionLevel ] ) addFileOrDirectory( { name => $name [, zipName => $newName, compressionLevel => $compressionLevel ] } ) Append a member from the file or directory named $name. If $newName is given, use it for the name of the new member. Will add or remove trailing slashes from $newName as needed. $name must be in local file system format. The optional second argument sets the name of the archive member (which defaults to $name). If given, it must be in Zip (Unix) format. addString( $stringOrStringRef, $name, [$compressionLevel] ) addString( { string => $stringOrStringRef [, zipName => $name, compressionLevel => $compressionLevel ] } ) Append a member created from the given string or string reference. The name is given by the second argument. Returns the new member. The last modification time will be set to now, and the file attributes will be set to permissive defaults. my $member = $zip->addString( 'This is a test', 'test.txt' ); contents( $memberOrMemberName [, $newContents ] ) contents( { memberOrZipName => $memberOrMemberName [, contents => $newContents ] } ) Returns the uncompressed data for a particular member, or undef. print "xyz.txt contains " . $zip->contents( 'xyz.txt' ); Also can change the contents of a member: $zip->contents( 'xyz.txt', 'This is the new contents' ); If called expecting an array as the return value, it will include the status as the second value in the array. ($content, $status) = $zip->contents( 'xyz.txt'); Zip Archive I/O operations A Zip archive can be written to a file or file handle, or read from one. writeToFileNamed( $fileName ) writeToFileNamed( { fileName => $fileName } ) Write a zip archive to named file. Returns "AZ_OK" on success. my $status = $zip->writeToFileNamed( 'xx.zip' ); die "error somewhere" if $status != AZ_OK; Note that if you use the same name as an existing zip file that you read in, you will clobber ZipFileMembers. So instead, write to a different file name, then delete the original. If you use the "overwrite()" or "overwriteAs()" methods, you can re-write the original zip in this way. $fileName should be a valid file name on your system. writeToFileHandle( $fileHandle [, $seekable] ) Write a zip archive to a file handle. Return AZ_OK on success. The optional second arg tells whether or not to try to seek backwards to re-write headers. If not provided, it is set if the Perl "-f" test returns true. This could fail on some operating systems, though. my $fh = IO::File->new( 'someFile.zip', 'w' ); unless ( $zip->writeToFileHandle( $fh ) == AZ_OK ) { # error handling } If you pass a file handle that is not seekable (like if you're writing to a pipe or a socket), pass a false second argument: my $fh = IO::File->new( '| cat > somefile.zip', 'w' ); $zip->writeToFileHandle( $fh, 0 ); # fh is not seekable If this method fails during the write of a member, that member and all following it will return false from "wasWritten()". See writeCentralDirectory() for a way to deal with this. If you want, you can write data to the file handle before passing it to writeToFileHandle(); this could be used (for instance) for making self-extracting archives. However, this only works reliably when writing to a real file (as opposed to STDOUT or some other possible non-file). See examples/selfex.pl for how to write a self-extracting archive. writeCentralDirectory( $fileHandle [, $offset ] ) writeCentralDirectory( { fileHandle => $fileHandle [, offset => $offset ] } ) Writes the central directory structure to the given file handle. Returns AZ_OK on success. If given an $offset, will seek to that point before writing. This can be used for recovery in cases where writeToFileHandle or writeToFileNamed returns an IO error because of running out of space on the destination file. You can truncate the zip by seeking backwards and then writing the directory: my $fh = IO::File->new( 'someFile.zip', 'w' ); my $retval = $zip->writeToFileHandle( $fh ); if ( $retval == AZ_IO_ERROR ) { my @unwritten = grep { not $_->wasWritten() } $zip->members(); if (@unwritten) { $zip->removeMember( $member ) foreach my $member ( @unwritten ); $zip->writeCentralDirectory( $fh, $unwritten[0]->writeLocalHeaderRelativeOffset()); } } overwriteAs( $newName ) overwriteAs( { filename => $newName } ) Write the zip to the specified file, as safely as possible. This is done by first writing to a temp file, then renaming the original if it exists, then renaming the temp file, then deleting the renamed original if it exists. Returns AZ_OK if successful. overwrite() Write back to the original zip file. See overwriteAs() above. If the zip was not ever read from a file, this generates an error. read( $fileName ) read( { filename => $fileName } ) Read zipfile headers from a zip file, appending new members. Returns "AZ_OK" or error code. my $zipFile = Archive::Zip->new(); my $status = $zipFile->read( '/some/FileName.zip' ); readFromFileHandle( $fileHandle, $filename ) readFromFileHandle( { fileHandle => $fileHandle, filename => $filename } ) Read zipfile headers from an already-opened file handle, appending new members. Does not close the file handle. Returns "AZ_OK" or error code. Note that this requires a seekable file handle; reading from a stream is not yet supported. my $fh = IO::File->new( '/some/FileName.zip', 'r' ); my $zip1 = Archive::Zip->new(); my $status = $zip1->readFromFileHandle( $fh ); my $zip2 = Archive::Zip->new(); $status = $zip2->readFromFileHandle( $fh ); Zip Archive Tree operations These used to be in Archive::Zip::Tree but got moved into Archive::Zip. They enable operation on an entire tree of members or files. A usage example: use Archive::Zip; my $zip = Archive::Zip->new(); # add all readable files and directories below . as xyz/* $zip->addTree( '.', 'xyz' ); # add all readable plain files below /abc as def/* $zip->addTree( '/abc', 'def', sub { -f && -r } ); # add all .c files below /tmp as stuff/* $zip->addTreeMatching( '/tmp', 'stuff', '\.c$' ); # add all .o files below /tmp as stuff/* if they aren't writable $zip->addTreeMatching( '/tmp', 'stuff', '\.o$', sub { ! -w } ); # add all .so files below /tmp that are smaller than 200 bytes as stuff/* $zip->addTreeMatching( '/tmp', 'stuff', '\.o$', sub { -s < 200 } ); # and write them into a file $zip->writeToFileNamed('xxx.zip'); # now extract the same files into /tmpx $zip->extractTree( 'stuff', '/tmpx' ); $zip->addTree( $root, $dest [, $pred, $compressionLevel ] ) -- Add tree of files to a zip $zip->addTree( { root => $root, zipName => $dest [, select => $pred, compressionLevel => $compressionLevel ] ) $root is the root of the tree of files and directories to be added. It is a valid directory name on your system. $dest is the name for the root in the zip file (undef or blank means to use relative pathnames). It is a valid ZIP directory name (that is, it uses forward slashes (/) for separating directory components). $pred is an optional subroutine reference to select files: it is passed the name of the prospective file or directory using $_, and if it returns true, the file or directory will be included. The default is to add all readable files and directories. For instance, using my $pred = sub { /\.txt/ }; $zip->addTree( '.', '', $pred ); will add all the .txt files in and below the current directory, using relative names, and making the names identical in the zipfile: original name zip member name ./xyz xyz ./a/ a/ ./a/b a/b To translate absolute to relative pathnames, just pass them in: $zip->addTree( '/c/d', 'a' ); original name zip member name /c/d/xyz a/xyz /c/d/a/ a/a/ /c/d/a/b a/a/b Returns AZ_OK on success. Note that this will not follow symbolic links to directories. Note also that this does not check for the validity of filenames. Note that you generally *don't* want to make zip archive member names absolute. $zip->addTreeMatching( $root, $dest, $pattern [, $pred, $compressionLevel ] ) $zip->addTreeMatching( { root => $root, zipName => $dest, pattern => $pattern [, select => $pred, compressionLevel => $compressionLevel ] } ) $root is the root of the tree of files and directories to be added $dest is the name for the root in the zip file (undef means to use relative pathnames) $pattern is a (non-anchored) regular expression for filenames to match $pred is an optional subroutine reference to select files: it is passed the name of the prospective file or directory in $_, and if it returns true, the file or directory will be included. The default is to add all readable files and directories. To add all files in and below the current directory whose names end in ".pl", and make them extract into a subdirectory named "xyz", do this: $zip->addTreeMatching( '.', 'xyz', '\.pl$' ) To add all *writable* files in and below the directory named "/abc" whose names end in ".pl", and make them extract into a subdirectory named "xyz", do this: $zip->addTreeMatching( '/abc', 'xyz', '\.pl$', sub { -w } ) Returns AZ_OK on success. Note that this will not follow symbolic links to directories. $zip->updateTree( $root [, $dest , $pred , $mirror, $compressionLevel ] ); $zip->updateTree( { root => $root [, zipName => $dest, select => $pred, mirror => $mirror, compressionLevel => $compressionLevel ] } ); Update a zip file from a directory tree. "updateTree()" takes the same arguments as "addTree()", but first checks to see whether the file or directory already exists in the zip file, and whether it has been changed. If the fourth argument $mirror is true, then delete all my members if corresponding files were not found. Returns an error code or AZ_OK if all is well. $zip->extractTree( [ $root, $dest, $volume } ] ) $zip->extractTree( [ { root => $root, zipName => $dest, volume => $volume } ] ) If you don't give any arguments at all, will extract all the files in the zip with their original names. If you supply one argument for $root, "extractTree" will extract all the members whose names start with $root into the current directory, stripping off $root first. $root is in Zip (Unix) format. For instance, $zip->extractTree( 'a' ); when applied to a zip containing the files: a/x a/b/c ax/d/e d/e will extract: a/x as ./x a/b/c as ./b/c If you give two arguments, "extractTree" extracts all the members whose names start with $root. It will translate $root into $dest to construct the destination file name. $root and $dest are in Zip (Unix) format. For instance, $zip->extractTree( 'a', 'd/e' ); when applied to a zip containing the files: a/x a/b/c ax/d/e d/e will extract: a/x to d/e/x a/b/c to d/e/b/c and ignore ax/d/e and d/e If you give three arguments, "extractTree" extracts all the members whose names start with $root. It will translate $root into $dest to construct the destination file name, and then it will convert to local file system format, using $volume as the name of the destination volume. $root and $dest are in Zip (Unix) format. $volume is in local file system format. For instance, under Windows, $zip->extractTree( 'a', 'd/e', 'f:' ); when applied to a zip containing the files: a/x a/b/c ax/d/e d/e will extract: a/x to f:d/e/x a/b/c to f:d/e/b/c and ignore ax/d/e and d/e If you want absolute paths (the prior example used paths relative to the current directory on the destination volume, you can specify these in $dest: $zip->extractTree( 'a', '/d/e', 'f:' ); when applied to a zip containing the files: a/x a/b/c ax/d/e d/e will extract: a/x to f:\d\e\x a/b/c to f:\d\e\b\c and ignore ax/d/e and d/e Returns an error code or AZ_OK if everything worked OK. Archive::Zip Global Variables $Archive::Zip::UNICODE This variable governs how Unicode file and directory names are added to or extracted from an archive. If set, file and directory names are considered to be UTF-8 encoded. This is *EXPERIMENTAL AND BUGGY (there are some edge cases on Win32)*. Please report problems. { local $Archive::Zip::UNICODE = 1; $zip->addFile('Dj vu.txt'); } MEMBER OPERATIONS Member Class Methods Several constructors allow you to construct members without adding them to a zip archive. These work the same as the addFile(), addDirectory(), and addString() zip instance methods described above, but they don't add the new members to a zip. Archive::Zip::Member->newFromString( $stringOrStringRef [, $fileName ] ) Archive::Zip::Member->newFromString( { string => $stringOrStringRef [, zipName => $fileName ] ) Construct a new member from the given string. Returns undef on error. my $member = Archive::Zip::Member->newFromString( 'This is a test', newFromFile( $fileName [, $zipName ] ) newFromFile( { filename => $fileName [, zipName => $zipName ] } ) Construct a new member from the given file. Returns undef on error. my $member = Archive::Zip::Member->newFromFile( 'xyz.txt' ); newDirectoryNamed( $directoryName [, $zipname ] ) newDirectoryNamed( { directoryName => $directoryName [, zipName => $zipname ] } ) Construct a new member from the given directory. $directoryName must be a valid name on your file system; it does not have to exist. If given, $zipname will be the name of the zip member; it must be a valid Zip (Unix) name. If not given, it will be converted from $directoryName. Returns undef on error. my $member = Archive::Zip::Member->newDirectoryNamed( 'CVS/' ); Member Simple accessors These methods get (and/or set) member attribute values. versionMadeBy() Gets the field from the member header. fileAttributeFormat( [ $format ] ) fileAttributeFormat( [ { format => $format ] } ) Gets or sets the field from the member header. These are "FA_*" values. versionNeededToExtract() Gets the field from the member header. bitFlag() Gets the general purpose bit field from the member header. This is where the "GPBF_*" bits live. compressionMethod() Returns the member compression method. This is the method that is currently being used to compress the member data. This will be COMPRESSION_STORED for added string or file members, or any of the "COMPRESSION_*" values for members from a zip file. However, this module can only handle members whose data is in COMPRESSION_STORED or COMPRESSION_DEFLATED format. desiredCompressionMethod( [ $method ] ) desiredCompressionMethod( [ { compressionMethod => $method } ] ) Get or set the member's "desiredCompressionMethod". This is the compression method that will be used when the member is written. Returns prior desiredCompressionMethod. Only COMPRESSION_DEFLATED or COMPRESSION_STORED are valid arguments. Changing to COMPRESSION_STORED will change the member desiredCompressionLevel to 0; changing to COMPRESSION_DEFLATED will change the member desiredCompressionLevel to COMPRESSION_LEVEL_DEFAULT. desiredCompressionLevel( [ $level ] ) desiredCompressionLevel( [ { compressionLevel => $level } ] ) Get or set the member's desiredCompressionLevel This is the method that will be used to write. Returns prior desiredCompressionLevel. Valid arguments are 0 through 9, COMPRESSION_LEVEL_NONE, COMPRESSION_LEVEL_DEFAULT, COMPRESSION_LEVEL_BEST_COMPRESSION, and COMPRESSION_LEVEL_FASTEST. 0 or COMPRESSION_LEVEL_NONE will change the desiredCompressionMethod to COMPRESSION_STORED. All other arguments will change the desiredCompressionMethod to COMPRESSION_DEFLATED. externalFileName() Return the member's external file name, if any, or undef. fileName() Get or set the member's internal filename. Returns the (possibly new) filename. Names will have backslashes converted to forward slashes, and will have multiple consecutive slashes converted to single ones. lastModFileDateTime() Return the member's last modification date/time stamp in MS-DOS format. lastModTime() Return the member's last modification date/time stamp, converted to unix localtime format. print "Mod Time: " . scalar( localtime( $member->lastModTime() ) ); setLastModFileDateTimeFromUnix() Set the member's lastModFileDateTime from the given unix time. $member->setLastModFileDateTimeFromUnix( time() ); internalFileAttributes() Return the internal file attributes field from the zip header. This is only set for members read from a zip file. externalFileAttributes() Return member attributes as read from the ZIP file. Note that these are NOT UNIX! unixFileAttributes( [ $newAttributes ] ) unixFileAttributes( [ { attributes => $newAttributes } ] ) Get or set the member's file attributes using UNIX file attributes. Returns old attributes. my $oldAttribs = $member->unixFileAttributes( 0666 ); Note that the return value has more than just the file permissions, so you will have to mask off the lowest bits for comparisons. localExtraField( [ $newField ] ) localExtraField( [ { field => $newField } ] ) Gets or sets the extra field that was read from the local header. This is not set for a member from a zip file until after the member has been written out. The extra field must be in the proper format. cdExtraField( [ $newField ] ) cdExtraField( [ { field => $newField } ] ) Gets or sets the extra field that was read from the central directory header. The extra field must be in the proper format. extraFields() Return both local and CD extra fields, concatenated. fileComment( [ $newComment ] ) fileComment( [ { comment => $newComment } ] ) Get or set the member's file comment. hasDataDescriptor() Get or set the data descriptor flag. If this is set, the local header will not necessarily have the correct data sizes. Instead, a small structure will be stored at the end of the member data with these values. This should be transparent in normal operation. crc32() Return the CRC-32 value for this member. This will not be set for members that were constructed from strings or external files until after the member has been written. crc32String() Return the CRC-32 value for this member as an 8 character printable hex string. This will not be set for members that were constructed from strings or external files until after the member has been written. compressedSize() Return the compressed size for this member. This will not be set for members that were constructed from strings or external files until after the member has been written. uncompressedSize() Return the uncompressed size for this member. password( [ $password ] ) Returns the password for this member to be used on decryption. If $password is given, it will set the password for the decryption. isEncrypted() Return true if this member is encrypted. The Archive::Zip module does not currently support creation of encrypted members. Decryption works more or less like this: my $zip = Archive::Zip->new; $zip->read ("encrypted.zip"); for my $m (map { $zip->memberNamed ($_) } $zip->memberNames) { $m->password ("secret"); $m->contents; # is "" when password was wrong That shows that the password has to be set per member, and not per archive. This might change in the future. isTextFile( [ $flag ] ) isTextFile( [ { flag => $flag } ] ) Returns true if I am a text file. Also can set the status if given an argument (then returns old state). Note that this module does not currently do anything with this flag upon extraction or storage. That is, bytes are stored in native format whether or not they came from a text file. isBinaryFile() Returns true if I am a binary file. Also can set the status if given an argument (then returns old state). Note that this module does not currently do anything with this flag upon extraction or storage. That is, bytes are stored in native format whether or not they came from a text file. extractToFileNamed( $fileName ) extractToFileNamed( { name => $fileName } ) Extract me to a file with the given name. The file will be created with default modes. Directories will be created as needed. The $fileName argument should be a valid file name on your file system. Returns AZ_OK on success. isDirectory() Returns true if I am a directory. writeLocalHeaderRelativeOffset() Returns the file offset in bytes the last time I was written. wasWritten() Returns true if I was successfully written. Reset at the beginning of a write attempt. Low-level member data reading It is possible to use lower-level routines to access member data streams, rather than the extract* methods and contents(). For instance, here is how to print the uncompressed contents of a member in chunks using these methods: my ( $member, $status, $bufferRef ); $member = $zip->memberNamed( 'xyz.txt' ); $member->desiredCompressionMethod( COMPRESSION_STORED ); $status = $member->rewindData(); die "error $status" unless $status == AZ_OK; while ( ! $member->readIsDone() ) { ( $bufferRef, $status ) = $member->readChunk(); die "error $status" if $status != AZ_OK && $status != AZ_STREAM_END; # do something with $bufferRef: print $$bufferRef; } $member->endRead(); readChunk( [ $chunkSize ] ) readChunk( [ { chunkSize => $chunkSize } ] ) This reads the next chunk of given size from the member's data stream and compresses or uncompresses it as necessary, returning a reference to the bytes read and a status. If size argument is not given, defaults to global set by Archive::Zip::setChunkSize. Status is AZ_OK on success until the last chunk, where it returns AZ_STREAM_END. Returns "( \$bytes, $status)". my ( $outRef, $status ) = $self->readChunk(); print $$outRef if $status != AZ_OK && $status != AZ_STREAM_END; rewindData() Rewind data and set up for reading data streams or writing zip files. Can take options for "inflateInit()" or "deflateInit()", but this is not likely to be necessary. Subclass overrides should call this method. Returns "AZ_OK" on success. endRead() Reset the read variables and free the inflater or deflater. Must be called to close files, etc. Returns AZ_OK on success. readIsDone() Return true if the read has run out of data or encountered an error. contents() Return the entire uncompressed member data or undef in scalar context. When called in array context, returns "( $string, $status )"; status will be AZ_OK on success: my $string = $member->contents(); # or my ( $string, $status ) = $member->contents(); die "error $status" unless $status == AZ_OK; Can also be used to set the contents of a member (this may change the class of the member): $member->contents( "this is my new contents" ); extractToFileHandle( $fh ) extractToFileHandle( { fileHandle => $fh } ) Extract (and uncompress, if necessary) the member's contents to the given file handle. Return AZ_OK on success. Archive::Zip::FileMember methods The Archive::Zip::FileMember class extends Archive::Zip::Member. It is the base class for both ZipFileMember and NewFileMember classes. This class adds an "externalFileName" and an "fh" member to keep track of the external file. externalFileName() Return the member's external filename. fh() Return the member's read file handle. Automatically opens file if necessary. Archive::Zip::ZipFileMember methods The Archive::Zip::ZipFileMember class represents members that have been read from external zip files. diskNumberStart() Returns the disk number that the member's local header resides in. Should be 0. localHeaderRelativeOffset() Returns the offset into the zip file where the member's local header is. dataOffset() Returns the offset from the beginning of the zip file to the member's data. REQUIRED MODULES Archive::Zip requires several other modules: Carp Compress::Raw::Zlib Cwd File::Basename File::Copy File::Find File::Path File::Spec IO::File IO::Seekable Time::Local BUGS AND CAVEATS When not to use Archive::Zip If you are just going to be extracting zips (and/or other archives) you are recommended to look at using Archive::Extract instead, as it is much easier to use and factors out archive-specific functionality. Try to avoid IO::Scalar One of the most common ways to use Archive::Zip is to generate Zip files in-memory. Most people have use IO::Scalar for this purpose. Unfortunately, as of 1.11 this module no longer works with IO::Scalar as it incorrectly implements seeking. Anybody using IO::Scalar should consider porting to IO::String, which is smaller, lighter, and is implemented to be perfectly compatible with regular seekable filehandles. Support for IO::Scalar most likely will not be restored in the future, as IO::Scalar itself cannot change the way it is implemented due to back-compatibility issues. Wrong password for encrypted members When an encrypted member is read using the wrong password, you currently have to re-read the entire archive to try again with the correct password. TO DO * auto-choosing storing vs compression * extra field hooks (see notes.txt) * check for duplicates on addition/renaming? * Text file extraction (line end translation) * Reading zip files from non-seekable inputs (Perhaps by proxying through IO::String?) * separate unused constants into separate module * cookbook style docs * Handle tainted paths correctly * Work on better compatibility with other IO:: modules * Support encryption * More user-friendly decryption SUPPORT Bugs should be reported via the CPAN bug tracker For other issues contact the maintainer AUTHOR Adam Kennedy Previously maintained by Steve Peters .

Line # up the first '|' above the ':' following the base package name, and the '|' # on the right side marks the last column you can put a character in. You must # make exactly 11 lines for the formatting to be correct. It's also # customary to leave one space after the ':'. |-----handy-ruler------------------------------------------------------| perl-archive-zip: perl-archive-zip (perl mod for manipulating zip files) perl-archive-zip: perl-archive-zip: The Archive::Zip module allows a Perl program to create, perl-archive-zip: manipulate, read, and write Zip archive files. perl-archive-zip: perl-archive-zip: This module uses the Compress::Zlib library to read and write perl-archive-zip: the compressed streams inside the files. perl-archive-zip: perl-archive-zip: perl-archive-zip: Homepage: http://search.cpan.org/~adamk/ perl-archive-zip:
