DESCRIPTION

54       This module provides a Perl interface that allows the reading of
55       files/buffers that have been compressed in a number of formats that use
56       the zlib compression library.
57
58       The formats supported are
59
60       RFC 1950
61       RFC 1951 (optionally)
62       gzip (RFC 1952)
63       zip
64
65       The module will auto-detect which, if any, of the supported compression
66       formats is being used.
67

Functional Interface

69       A top-level function, "anyinflate", is provided to carry out "one-shot"
70       uncompression between buffers and/or files. For finer control over the
71       uncompression process, see the "OO Interface" section.
72
73           use IO::Uncompress::AnyInflate qw(anyinflate $AnyInflateError) ;
74
75           anyinflate $input_filename_or_reference => $output_filename_or_reference [,OPTS]
76               or die "anyinflate failed: $AnyInflateError\n";
77
78       The functional interface needs Perl5.005 or better.
79
80   anyinflate $input_filename_or_reference => $output_filename_or_reference [,
81       OPTS]
82       "anyinflate" expects at least two parameters,
83       $input_filename_or_reference and $output_filename_or_reference.
84
85       The $input_filename_or_reference parameter
86
87       The parameter, $input_filename_or_reference, is used to define the
88       source of the compressed data.
89
90       It can take one of the following forms:
91
92       A filename
93            If the <$input_filename_or_reference> parameter is a simple
94            scalar, it is assumed to be a filename. This file will be opened
95            for reading and the input data will be read from it.
96
97       A filehandle
98            If the $input_filename_or_reference parameter is a filehandle, the
99            input data will be read from it.  The string '-' can be used as an
100            alias for standard input.
101
102       A scalar reference
103            If $input_filename_or_reference is a scalar reference, the input
104            data will be read from $$input_filename_or_reference.
105
106       An array reference
107            If $input_filename_or_reference is an array reference, each
108            element in the array must be a filename.
109
110            The input data will be read from each file in turn.
111
112            The complete array will be walked to ensure that it only contains
113            valid filenames before any data is uncompressed.
114
115       An Input FileGlob string
116            If $input_filename_or_reference is a string that is delimited by
117            the characters "<" and ">" "anyinflate" will assume that it is an
118            input fileglob string. The input is the list of files that match
119            the fileglob.
120
121            See File::GlobMapper for more details.
122
123       If the $input_filename_or_reference parameter is any other type,
124       "undef" will be returned.
125
126       The $output_filename_or_reference parameter
127
128       The parameter $output_filename_or_reference is used to control the
129       destination of the uncompressed data. This parameter can take one of
130       these forms.
131
132       A filename
133            If the $output_filename_or_reference parameter is a simple scalar,
134            it is assumed to be a filename.  This file will be opened for
135            writing and the uncompressed data will be written to it.
136
137       A filehandle
138            If the $output_filename_or_reference parameter is a filehandle,
139            the uncompressed data will be written to it.  The string '-' can
140            be used as an alias for standard output.
141
142       A scalar reference
143            If $output_filename_or_reference is a scalar reference, the
144            uncompressed data will be stored in
145            $$output_filename_or_reference.
146
147       An Array Reference
148            If $output_filename_or_reference is an array reference, the
149            uncompressed data will be pushed onto the array.
150
151       An Output FileGlob
152            If $output_filename_or_reference is a string that is delimited by
153            the characters "<" and ">" "anyinflate" will assume that it is an
154            output fileglob string. The output is the list of files that match
155            the fileglob.
156
157            When $output_filename_or_reference is an fileglob string,
158            $input_filename_or_reference must also be a fileglob string.
159            Anything else is an error.
160
161            See File::GlobMapper for more details.
162
163       If the $output_filename_or_reference parameter is any other type,
164       "undef" will be returned.
165
166   Notes
167       When $input_filename_or_reference maps to multiple compressed
168       files/buffers and $output_filename_or_reference is a single
169       file/buffer, after uncompression $output_filename_or_reference will
170       contain a concatenation of all the uncompressed data from each of the
171       input files/buffers.
172
173   Optional Parameters
174       Unless specified below, the optional parameters for "anyinflate",
175       "OPTS", are the same as those used with the OO interface defined in the
176       "Constructor Options" section below.
177
178       "AutoClose => 0|1"
179            This option applies to any input or output data streams to
180            "anyinflate" that are filehandles.
181
182            If "AutoClose" is specified, and the value is true, it will result
183            in all input and/or output filehandles being closed once
184            "anyinflate" has completed.
185
186            This parameter defaults to 0.
187
188       "BinModeOut => 0|1"
189            This option is now a no-op. All files will be written  in binmode.
190
191       "Append => 0|1"
192            The behaviour of this option is dependent on the type of output
193            data stream.
194
195            ·    A Buffer
196
197                 If "Append" is enabled, all uncompressed data will be append
198                 to the end of the output buffer. Otherwise the output buffer
199                 will be cleared before any uncompressed data is written to
200                 it.
201
202            ·    A Filename
203
204                 If "Append" is enabled, the file will be opened in append
205                 mode. Otherwise the contents of the file, if any, will be
206                 truncated before any uncompressed data is written to it.
207
208            ·    A Filehandle
209
210                 If "Append" is enabled, the filehandle will be positioned to
211                 the end of the file via a call to "seek" before any
212                 uncompressed data is written to it.  Otherwise the file
213                 pointer will not be moved.
214
215            When "Append" is specified, and set to true, it will append all
216            uncompressed data to the output data stream.
217
218            So when the output is a filehandle it will carry out a seek to the
219            eof before writing any uncompressed data. If the output is a
220            filename, it will be opened for appending. If the output is a
221            buffer, all uncompressed data will be appended to the existing
222            buffer.
223
224            Conversely when "Append" is not specified, or it is present and is
225            set to false, it will operate as follows.
226
227            When the output is a filename, it will truncate the contents of
228            the file before writing any uncompressed data. If the output is a
229            filehandle its position will not be changed. If the output is a
230            buffer, it will be wiped before any uncompressed data is output.
231
232            Defaults to 0.
233
234       "MultiStream => 0|1"
235            If the input file/buffer contains multiple compressed data
236            streams, this option will uncompress the whole lot as a single
237            data stream.
238
239            Defaults to 0.
240
241       "TrailingData => $scalar"
242            Returns the data, if any, that is present immediately after the
243            compressed data stream once uncompression is complete.
244
245            This option can be used when there is useful information
246            immediately following the compressed data stream, and you don't
247            know the length of the compressed data stream.
248
249            If the input is a buffer, "trailingData" will return everything
250            from the end of the compressed data stream to the end of the
251            buffer.
252
253            If the input is a filehandle, "trailingData" will return the data
254            that is left in the filehandle input buffer once the end of the
255            compressed data stream has been reached. You can then use the
256            filehandle to read the rest of the input file.
257
258            Don't bother using "trailingData" if the input is a filename.
259
260            If you know the length of the compressed data stream before you
261            start uncompressing, you can avoid having to use "trailingData" by
262            setting the "InputLength" option.
263
264   Examples
265       To read the contents of the file "file1.txt.Compressed" and write the
266       uncompressed data to the file "file1.txt".
267
268           use strict ;
269           use warnings ;
270           use IO::Uncompress::AnyInflate qw(anyinflate $AnyInflateError) ;
271
272           my $input = "file1.txt.Compressed";
273           my $output = "file1.txt";
274           anyinflate $input => $output
275               or die "anyinflate failed: $AnyInflateError\n";
276
277       To read from an existing Perl filehandle, $input, and write the
278       uncompressed data to a buffer, $buffer.
279
280           use strict ;
281           use warnings ;
282           use IO::Uncompress::AnyInflate qw(anyinflate $AnyInflateError) ;
283           use IO::File ;
284
285           my $input = new IO::File "<file1.txt.Compressed"
286               or die "Cannot open 'file1.txt.Compressed': $!\n" ;
287           my $buffer ;
288           anyinflate $input => \$buffer
289               or die "anyinflate failed: $AnyInflateError\n";
290
291       To uncompress all files in the directory "/my/home" that match
292       "*.txt.Compressed" and store the compressed data in the same directory
293
294           use strict ;
295           use warnings ;
296           use IO::Uncompress::AnyInflate qw(anyinflate $AnyInflateError) ;
297
298           anyinflate '</my/home/*.txt.Compressed>' => '</my/home/#1.txt>'
299               or die "anyinflate failed: $AnyInflateError\n";
300
301       and if you want to compress each file one at a time, this will do the
302       trick
303
304           use strict ;
305           use warnings ;
306           use IO::Uncompress::AnyInflate qw(anyinflate $AnyInflateError) ;
307
308           for my $input ( glob "/my/home/*.txt.Compressed" )
309           {
310               my $output = $input;
311               $output =~ s/.Compressed// ;
312               anyinflate $input => $output
313                   or die "Error compressing '$input': $AnyInflateError\n";
314           }
315

OO Interface

317   Constructor
318       The format of the constructor for IO::Uncompress::AnyInflate is shown
319       below
320
321           my $z = new IO::Uncompress::AnyInflate $input [OPTS]
322               or die "IO::Uncompress::AnyInflate failed: $AnyInflateError\n";
323
324       Returns an "IO::Uncompress::AnyInflate" object on success and undef on
325       failure.  The variable $AnyInflateError will contain an error message
326       on failure.
327
328       If you are running Perl 5.005 or better the object, $z, returned from
329       IO::Uncompress::AnyInflate can be used exactly like an IO::File
330       filehandle.  This means that all normal input file operations can be
331       carried out with $z.  For example, to read a line from a compressed
332       file/buffer you can use either of these forms
333
334           $line = $z->getline();
335           $line = <$z>;
336
337       The mandatory parameter $input is used to determine the source of the
338       compressed data. This parameter can take one of three forms.
339
340       A filename
341            If the $input parameter is a scalar, it is assumed to be a
342            filename. This file will be opened for reading and the compressed
343            data will be read from it.
344
345       A filehandle
346            If the $input parameter is a filehandle, the compressed data will
347            be read from it.  The string '-' can be used as an alias for
348            standard input.
349
350       A scalar reference
351            If $input is a scalar reference, the compressed data will be read
352            from $$input.
353
354   Constructor Options
355       The option names defined below are case insensitive and can be
356       optionally prefixed by a '-'.  So all of the following are valid
357
358           -AutoClose
359           -autoclose
360           AUTOCLOSE
361           autoclose
362
363       OPTS is a combination of the following options:
364
365       "AutoClose => 0|1"
366            This option is only valid when the $input parameter is a
367            filehandle. If specified, and the value is true, it will result in
368            the file being closed once either the "close" method is called or
369            the IO::Uncompress::AnyInflate object is destroyed.
370
371            This parameter defaults to 0.
372
373       "MultiStream => 0|1"
374            Allows multiple concatenated compressed streams to be treated as a
375            single compressed stream. Decompression will stop once either the
376            end of the file/buffer is reached, an error is encountered
377            (premature eof, corrupt compressed data) or the end of a stream is
378            not immediately followed by the start of another stream.
379
380            This parameter defaults to 0.
381
382       "Prime => $string"
383            This option will uncompress the contents of $string before
384            processing the input file/buffer.
385
386            This option can be useful when the compressed data is embedded in
387            another file/data structure and it is not possible to work out
388            where the compressed data begins without having to read the first
389            few bytes. If this is the case, the uncompression can be primed
390            with these bytes using this option.
391
392       "Transparent => 0|1"
393            If this option is set and the input file/buffer is not compressed
394            data, the module will allow reading of it anyway.
395
396            In addition, if the input file/buffer does contain compressed data
397            and there is non-compressed data immediately following it, setting
398            this option will make this module treat the whole file/buffer as a
399            single data stream.
400
401            This option defaults to 1.
402
403       "BlockSize => $num"
404            When reading the compressed input data, IO::Uncompress::AnyInflate
405            will read it in blocks of $num bytes.
406
407            This option defaults to 4096.
408
409       "InputLength => $size"
410            When present this option will limit the number of compressed bytes
411            read from the input file/buffer to $size. This option can be used
412            in the situation where there is useful data directly after the
413            compressed data stream and you know beforehand the exact length of
414            the compressed data stream.
415
416            This option is mostly used when reading from a filehandle, in
417            which case the file pointer will be left pointing to the first
418            byte directly after the compressed data stream.
419
420            This option defaults to off.
421
422       "Append => 0|1"
423            This option controls what the "read" method does with uncompressed
424            data.
425
426            If set to 1, all uncompressed data will be appended to the output
427            parameter of the "read" method.
428
429            If set to 0, the contents of the output parameter of the "read"
430            method will be overwritten by the uncompressed data.
431
432            Defaults to 0.
433
434       "Strict => 0|1"
435            This option controls whether the extra checks defined below are
436            used when carrying out the decompression. When Strict is on, the
437            extra tests are carried out, when Strict is off they are not.
438
439            The default for this option is off.
440
441            If the input is an RFC 1950 data stream, the following will be
442            checked:
443
444            1.   The ADLER32 checksum field must be present.
445
446            2.   The value of the ADLER32 field read must match the adler32
447                 value of the uncompressed data actually contained in the
448                 file.
449
450            If the input is a gzip (RFC 1952) data stream, the following will
451            be checked:
452
453            1.   If the FHCRC bit is set in the gzip FLG header byte, the
454                 CRC16 bytes in the header must match the crc16 value of the
455                 gzip header actually read.
456
457            2.   If the gzip header contains a name field (FNAME) it consists
458                 solely of ISO 8859-1 characters.
459
460            3.   If the gzip header contains a comment field (FCOMMENT) it
461                 consists solely of ISO 8859-1 characters plus line-feed.
462
463            4.   If the gzip FEXTRA header field is present it must conform to
464                 the sub-field structure as defined in RFC 1952.
465
466            5.   The CRC32 and ISIZE trailer fields must be present.
467
468            6.   The value of the CRC32 field read must match the crc32 value
469                 of the uncompressed data actually contained in the gzip file.
470
471            7.   The value of the ISIZE fields read must match the length of
472                 the uncompressed data actually read from the file.
473
474       "RawInflate => 0|1"
475            When auto-detecting the compressed format, try to test for raw-
476            deflate (RFC 1951) content using the "IO::Uncompress::RawInflate"
477            module.
478
479            The reason this is not default behaviour is because RFC 1951
480            content can only be detected by attempting to uncompress it. This
481            process is error prone and can result is false positives.
482
483            Defaults to 0.
484
485       "ParseExtra => 0|1" If the gzip FEXTRA header field is present and this
486       option is set, it will force the module to check that it conforms to
487       the sub-field structure as defined in RFC 1952.
488            If the "Strict" is on it will automatically enable this option.
489
490            Defaults to 0.

Methods

496   read
497       Usage is
498
499           $status = $z->read($buffer)
500
501       Reads a block of compressed data (the size of the compressed block is
502       determined by the "Buffer" option in the constructor), uncompresses it
503       and writes any uncompressed data into $buffer. If the "Append"
504       parameter is set in the constructor, the uncompressed data will be
505       appended to the $buffer parameter. Otherwise $buffer will be
506       overwritten.
507
508       Returns the number of uncompressed bytes written to $buffer, zero if
509       eof or a negative number on error.
510
511   read
512       Usage is
513
514           $status = $z->read($buffer, $length)
515           $status = $z->read($buffer, $length, $offset)
516
517           $status = read($z, $buffer, $length)
518           $status = read($z, $buffer, $length, $offset)
519
520       Attempt to read $length bytes of uncompressed data into $buffer.
521
522       The main difference between this form of the "read" method and the
523       previous one, is that this one will attempt to return exactly $length
524       bytes. The only circumstances that this function will not is if end-of-
525       file or an IO error is encountered.
526
527       Returns the number of uncompressed bytes written to $buffer, zero if
528       eof or a negative number on error.
529
530   getline
531       Usage is
532
533           $line = $z->getline()
534           $line = <$z>
535
536       Reads a single line.
537
538       This method fully supports the use of the variable $/ (or
539       $INPUT_RECORD_SEPARATOR or $RS when "English" is in use) to determine
540       what constitutes an end of line. Paragraph mode, record mode and file
541       slurp mode are all supported.
542
543   getc
544       Usage is
545
546           $char = $z->getc()
547
548       Read a single character.
549
550   ungetc
551       Usage is
552
553           $char = $z->ungetc($string)
554
555   inflateSync
556       Usage is
557
558           $status = $z->inflateSync()
559
560       TODO
561
562   getHeaderInfo
563       Usage is
564
565           $hdr  = $z->getHeaderInfo();
566           @hdrs = $z->getHeaderInfo();
567
568       This method returns either a hash reference (in scalar context) or a
569       list or hash references (in array context) that contains information
570       about each of the header fields in the compressed data stream(s).
571
572   tell
573       Usage is
574
575           $z->tell()
576           tell $z
577
578       Returns the uncompressed file offset.
579
580   eof
581       Usage is
582
583           $z->eof();
584           eof($z);
585
586       Returns true if the end of the compressed input stream has been
587       reached.
588
589   seek
590           $z->seek($position, $whence);
591           seek($z, $position, $whence);
592
593       Provides a sub-set of the "seek" functionality, with the restriction
594       that it is only legal to seek forward in the input file/buffer.  It is
595       a fatal error to attempt to seek backward.
596
597       Note that the implementation of "seek" in this module does not provide
598       true random access to a compressed file/buffer. It  works by
599       uncompressing data from the current offset in the file/buffer until it
600       reaches the uncompressed offset specified in the parameters to "seek".
601       For very small files this may be acceptable behaviour. For large files
602       it may cause an unacceptable delay.
603
604       The $whence parameter takes one the usual values, namely SEEK_SET,
605       SEEK_CUR or SEEK_END.
606
607       Returns 1 on success, 0 on failure.
608
609   binmode
610       Usage is
611
612           $z->binmode
613           binmode $z ;
614
615       This is a noop provided for completeness.
616
617   opened
618           $z->opened()
619
620       Returns true if the object currently refers to a opened file/buffer.
621
622   autoflush
623           my $prev = $z->autoflush()
624           my $prev = $z->autoflush(EXPR)
625
626       If the $z object is associated with a file or a filehandle, this method
627       returns the current autoflush setting for the underlying filehandle. If
628       "EXPR" is present, and is non-zero, it will enable flushing after every
629       write/print operation.
630
631       If $z is associated with a buffer, this method has no effect and always
632       returns "undef".
633
634       Note that the special variable $| cannot be used to set or retrieve the
635       autoflush setting.
636
637   input_line_number
638           $z->input_line_number()
639           $z->input_line_number(EXPR)
640
641       Returns the current uncompressed line number. If "EXPR" is present it
642       has the effect of setting the line number. Note that setting the line
643       number does not change the current position within the file/buffer
644       being read.
645
646       The contents of $/ are used to determine what constitutes a line
647       terminator.
648
649   fileno
650           $z->fileno()
651           fileno($z)
652
653       If the $z object is associated with a file or a filehandle, "fileno"
654       will return the underlying file descriptor. Once the "close" method is
655       called "fileno" will return "undef".
656
657       If the $z object is associated with a buffer, this method will return
658       "undef".
659
660   close
661           $z->close() ;
662           close $z ;
663
664       Closes the output file/buffer.
665
666       For most versions of Perl this method will be automatically invoked if
667       the IO::Uncompress::AnyInflate object is destroyed (either explicitly
668       or by the variable with the reference to the object going out of
669       scope). The exceptions are Perl versions 5.005 through 5.00504 and
670       5.8.0. In these cases, the "close" method will be called automatically,
671       but not until global destruction of all live objects when the program
672       is terminating.
673
674       Therefore, if you want your scripts to be able to run on all versions
675       of Perl, you should call "close" explicitly and not rely on automatic
676       closing.
677
678       Returns true on success, otherwise 0.
679
680       If the "AutoClose" option has been enabled when the
681       IO::Uncompress::AnyInflate object was created, and the object is
682       associated with a file, the underlying file will also be closed.
683
684   nextStream
685       Usage is
686
687           my $status = $z->nextStream();
688
689       Skips to the next compressed data stream in the input file/buffer. If a
690       new compressed data stream is found, the eof marker will be cleared and
691       $.  will be reset to 0.
692
693       Returns 1 if a new stream was found, 0 if none was found, and -1 if an
694       error was encountered.
695
696   trailingData
697       Usage is
698
699           my $data = $z->trailingData();
700
701       Returns the data, if any, that is present immediately after the
702       compressed data stream once uncompression is complete. It only makes
703       sense to call this method once the end of the compressed data stream
704       has been encountered.
705
706       This option can be used when there is useful information immediately
707       following the compressed data stream, and you don't know the length of
708       the compressed data stream.
709
710       If the input is a buffer, "trailingData" will return everything from
711       the end of the compressed data stream to the end of the buffer.
712
713       If the input is a filehandle, "trailingData" will return the data that
714       is left in the filehandle input buffer once the end of the compressed
715       data stream has been reached. You can then use the filehandle to read
716       the rest of the input file.
717
718       Don't bother using "trailingData" if the input is a filename.
719
720       If you know the length of the compressed data stream before you start
721       uncompressing, you can avoid having to use "trailingData" by setting
722       the "InputLength" option in the constructor.
