6 | * IO::Uncompress::Base.pm |
7 | - Fixed problem with LimitOutput where a call to uncompress |
8 | created more uncompressed output, but didn't consume any of |
9 | the input buffer. The symptom is the underlying compression |
10 | library (zlib or bzip2) thinks the input stream is corrupt. |
11 | [RT #46582] |

18 | 2.018 3 May 2009 |
19 | |
20 | * IO::Unompress::Bunzip2 |
21 | - The interface to Compress-Raw-Bzip2 now uses the new LimitOutput |
22 | feature. This will make all of the bzip2-related IO-Compress modules |
23 | less greedy in their memory consumption. |
24 | |
25 | * IO::Compress::Zip |
26 | - Fixed exTime & exUnix2 |
27 | |
28 | - Fixed 'Use of uninitialized value in pack' warning when using |
29 | ZIP_CM_STORE. |

33 | * Merged IO-Compress-Base, IO-Compress-Bzip2, IO-Compress-Zlib & |
34 | Compress-Zlib into IO-Compress. |

36 | * The interface to Compress-Raw-Zlib now uses the new LimitOutput |
37 | feature. This will make all of the zlib-related IO-Compress modules |
38 | less greedy in their memory consumption. |
39 | |
40 | * Removed MAN3PODS from Makefile.PL |
41 | |
42 | * A few changes to get the test harness to work on VMS courtesy of |
43 | Craig. A. Berry. |
44 | |
319fab50 |
45 | * IO::Compress::Base & IO::Uncompress::Base |
46 | Downgraded some croaks in the constructors to just set $! (by letting |
47 | the code attempt to open a file and fail). |
48 | This makes the behavior more consistent to a standard open. |
49 | [RT #42657] |
50 | |
51 | * IO::Uncompress::Base |
52 | Doing a seek with MultiStream could drop some of the uncompressed |
53 | data. Fixed. |
54 | |
55 | * IO::Compress::Zip |
56 | - Fixed problem with the uncompressed & uncompressed fields when |
57 | zip64 is enabled. They were set to 0x0000FFFF instead of |
58 | 0xFFFFFFFF. Also the ZIP64 extra field was 4 bytes short. |
59 | Problem spotted by Dino Chiesa. |
60 | |
dc82791d |
61 | * IO::Uncompress::Unzip |
62 | - use POSIX::mktime instead of Time::Local::timelocal to convert |
63 | the zip DOS time field into Unix time. |
64 | |
319fab50 |
65 | * Compress::Zlib |
66 | - Documented Compress::Zlib::zlib_version() |
67 | |
68 | |
69 | 2.015 3 September 2008 |
70 | |
71 | * Makefile.PL |
72 | Backout changes made in 2.014 |
73 | |
74 | 2.014 2 September 2008 |
75 | |
76 | * Makefile.PL |
77 | Updated to check for indirect dependencies. |
78 | |
79 | 2.013 18 July 2008 |
80 | |
81 | * IO::Compress::Base |
82 | - Allow IO::Compress::Base::Parameters::parse to accept an |
83 | IO::Compress::Base::Parameters object. |
84 | |
85 | 2.012 15 July 2008 |
86 | |
87 | * IO::Compress::Base |
88 | - Silenced an uninitialised value warning when reading a line |
89 | at a time from a zip file where the content uses ZIP_CM_STORE. |
90 | [Problem spotted & fixed by Jeff Holt] |
91 | |
92 | * IO::Compress::Base & IO::Uncompress::Base |
93 | - local-ise $!, $? et al in the DESTROY methods. |
94 | |
95 | 2.011 17 May 2008 |
96 | |
97 | * IO::Compress::Base |
98 | - Fixed problem that prevented the creation of a zip file that |
99 | contained more than one compression method. |
100 | |
101 | * IO::Compress::Base::Common |
102 | - The private Validator class in this module clashes with another |
103 | CPAN module. Moved Validator into the IO::Compress::Base::Common |
104 | namespace. |
105 | [RT #35954] |
106 | |
107 | * IO::Uncompress::Unzip |
108 | - Print an error message if the zip file contains a |
109 | member compressed with bzip2 and IO::Uncompress::Bunzip2 is |
110 | not available. |
111 | - Could not cope with mixed compression zip files. For example a |
112 | zip file that contains both STORED and DEFLATED content. |
113 | [RT #35573] |
114 | |
115 | 2.010 5 May 2008 |
116 | |
117 | * Fixed problem that meant Perl 5.10 could not upgrade this module. |
118 | [RT #35342 & 35341] |
119 | |
120 | 2.009 20 April 2008 |
121 | |
122 | * Removed the alpha status from File::GlobMapper |
123 | |
124 | * IO::Compress::Base |
125 | When writing output never output a zero length buffer. |
126 | Done to improve interoperability with other tied filenandle |
127 | modules. |
128 | |
129 | * Changed IO::Uncompress::Base to not use the offset parameter of |
130 | the read method when reading from a filehandle. |
131 | |
132 | The object returned from Net::FTP::retr implements a non-standard |
133 | read method. The third parameter is used for a timeout value |
134 | rather than an offset. |
135 | [rt.cpan#33231] |
136 | |
137 | * Changed IO::Uncompress::Base to not use the eof method when |
138 | reading from a filehandle. |
139 | |
140 | The object returned from Net::FTP::retr implements both the read |
141 | method and the eof method. Unfortunately the implementation of |
142 | the read method uses non-buffered IO (by using sysread) while |
143 | the eof method uses buffered IO. Mixing buffered and non-buffered |
144 | IO results in data corruption. |
145 | |
146 | * IO::Compress::Zip |
147 | |
148 | - Added exUnix2 option to allow storing of UID & GID. |
149 | - When running on a Unix derivative the ExtAttr option now defaults |
150 | to the equivalent of 0666. For all other systems the default |
151 | remains 0. |
152 | |
153 | * Compress::Zlib |
154 | - Minor documentation issue with flush. |
155 | [rt.cpan.org #31446] |
156 | |
157 | |
158 | 2.008 2 November 2007 |
159 | |
160 | * Minor documentation changes in README |
161 | |
162 | * t/compress/truncate.pl |
163 | EBCDIC Cleanup. |
164 | |
165 | * IO::Compress::Gzip::Constants.pm |
166 | Tidied up the character classes used to defined invalid |
167 | FNAME & FCOMMENT fields for EBCDIC. |
168 | |
169 | * Compress::Zlib |
170 | lib/Compress/Zlib.pm -- 1.x Backward Compatability issues |
171 | gzclose - documented return value was wrong, should be 0 for ok. |
172 | gzflush - return value didn't match 1.x, should return 0 if ok. |
173 | [rt.cpan.org #29215] and Debian bug #440943 http://bugs.debian.org/440943 |
174 | |
175 | 2.006 1 September 20007 |
176 | |
177 | * Makefile.PL |
178 | Added INSTALLDIRS directive to install as a core module when built |
179 | on a perl >= 5.9. |
180 | |
181 | * IO::Uncompress::RawDeflate |
182 | |
183 | - Fixed export problem - "$RawDeflateError" and "rawdeflate" were |
184 | not being exported with ":all". |
185 | |
186 | * Compress::Zlib |
187 | - t/03zlib-v1.t |
188 | Fixed crc32 and adler32 tests in to remove ascii assumption. |
189 | |
190 | - lib/Compress/Zlib.pm |
191 | Make gzreadline not support $/, just like in Compress::Zlib 1.x |
192 | Folk who want $/ with readline support can get it in |
193 | IO::Uncompress::Gunzip. [rt.cpan.org #28663] and |
194 | Debian bug #435656 http://bugs.debian.org/435656 |
195 | |
196 | |
197 | 2.005 18 June 2007 |
198 | |
199 | * Stephen Turner reported a problem when using IO::Uncompress::Gunzip |
200 | with XML::Parser. Turns out there were two issues. |
201 | |
202 | Firstly an IO::Uncompress object isn't an IO::Handle. It is now. |
203 | |
204 | Secondly the implementation of "read" wasn't honouring this |
205 | |
206 | SCALAR will be grown or shrunk to the length actually read. |
207 | |
208 | In particular it didn't do the right thing on EOF. |
209 | This has been fixed. |
210 | |
211 | * IO::Compress::Gzip & IO::Uncompress::Gunzip |
212 | |
213 | - RFC1952 says that the FNAME & FCOMMENT header fields must be ISO |
214 | 8859-1 (LATIN-1) characters. The code can optionally police this. |
215 | Added a fix for this logic when running on EBCDIC. |
216 | |
217 | * Compress::Zlib |
218 | Added info about removing Compress::Zlib version 1, before |
219 | installing version 2. |
220 | |
221 | 2.004 3 March 2007 |
222 | |
223 | * Made seek less wasteful of memory. |
224 | |
225 | * IO::Compress::Zip |
226 | |
227 | - Added Zip64 documentation. |
228 | |
229 | - Fixed extended timestamp. |
230 | Creation time isn't available in Unix so only store the |
231 | modification time and the last access time in the extended field. |
232 | |
233 | - Fixed file mode. |
234 | |
235 | - Added ExtAttr option to control the value of the "external file |
236 | attributes" field in the central directory. |
237 | |
238 | - Added Unix2 extended attribute ("Ux"). |
239 | This stores the UID & GID. |
240 | |
241 | * IO::Compress::Gzip |
242 | |
243 | - Fixed 050interop-gzip.t for Windows |
244 | |
245 | * IO::Compress::Bzip2 |
246 | |
247 | - Fixed 050interop-bzip2.t for Windows |
248 | |
249 | * Compress::Zlib |
250 | |
251 | - rewrote memGzip using IO::Compress::Gzip::gzip |
252 | |
253 | 2.003 2 January 2007 |
254 | |
255 | * Added explicit version checking |
256 | |
257 | 2.002 29 December 2006 |
258 | |
259 | * Documentation updates. |
260 | |
261 | * Added IO::Handle to the ISA test in isaFilehandle |
262 | |
263 | * Add an explicit use_ok test for Scalar::Util in the test harness. |
264 | The error message reported by 01misc implied the problem was |
265 | somewhere else. |
266 | Also explictly check that 'dualvar' is available. |
267 | |
268 | * Compress::Zlib |
269 | - Fix append mode with gzopen. |
270 | rt-cpan.org 24041 |
271 | |
272 | - Allow gzopen to read from and write to a scalar reference. |
273 | |
274 | 2.001 1 November 2006 |
275 | |
276 | * Remove beta status. |
277 | |
278 | 2.000_14 26 October 2006 |
279 | |
280 | * IO::Uncompress::Base |
281 | Added support for $/ in record mode |
282 | |
283 | * IO::Uncompress::Base |
284 | The readline interface was substantially slower than the 1.x |
285 | equivalent. This has now been sorted. |
286 | Thanks to Andreas J. Koenig for spotting the problem. |
287 | |
288 | * IO::Uncompress::AnyUncompress |
289 | Added IO::Uncompress::Lzf to the list of supported uncompresors. |
290 | |
291 | * IO::Uncompress::Base |
292 | Added TrailingData to one-shot interface. |
293 | |
294 | * IO::Uncompress::AnyUncompress |
295 | Remove raw-deflate (RFC1951) from the default list of compressors |
296 | to check. |
297 | It can still be included if the new RawInflate parameter is |
298 | supplied. |
299 | This change was made because the only way to tell if content is |
300 | raw-deflate is to attempt to uncompress it - a few false positives |
301 | have popped up recently, which suggests that auto-detecting raw |
302 | deflate is far from perfect. |
303 | The equivalent change has been made to IO::Uncompress::AnyInflate. |
304 | [Core patch #28445] |
305 | |
306 | * Don't check that filehandles are writable. It would seem that |
307 | "-w *STDOUT" on windows returns false. |
308 | [Core Patch #28415] |
309 | |
310 | * IO::Uncompress::Deflate |
311 | Beefed up the magic signature check. Means less false positives |
312 | when auto-detecting the compression type. |
313 | |
314 | * IO::Uncompress::UnZip |
315 | Tighten up the zip64 extra field processing to cope with the case |
316 | wheere only some of the local header fields are superceeded. |
317 | |
318 | * IO::Uncompress::AnyInflate |
319 | Remove raw-deflate (RFC 1951) from the default list of compressors |
320 | to check. |
321 | It can still be included if the new RawInflate parameter is |
322 | supplied. |
323 | This change was made because the only way to tell if content is |
324 | raw-deflate is to attempt to uncompress it - a few false positives |
325 | have popped up recently, which suggests that auto-detecting raw |
326 | deflate is far from perfect. |
327 | The equivalent change has been made to IO::Uncompress::AnyUncompress. |
328 | [Core patch #28445] |
329 | |
330 | 2.000_13 20 June 2006 |
331 | |
332 | * Store compress & uncompressed sizes as 64-bit. |
333 | |
334 | * For one-shot uncompression, like this |
335 | |
336 | unzip "some.zip" => \@a, MultiStream => 1; |
337 | |
338 | Push each uncompressed stream from "some.zip" onto @a. |
339 | |
340 | * Added IO::Compress::Base::FilterEnvelope |
341 | |
342 | * Added IO::Uncompress::Base::nextStream |
343 | |
344 | * The '-' filehandle now maps to either *STDIN or *STDOUT. |
345 | This keeps mod_perl happier. Was using these before |
346 | |
347 | new IO::File("<-") |
348 | new IO::File(">-") |
349 | |
350 | * Preliminary support for reading zip files with zip64 members. |
351 | |
352 | 2.000_12 3 May 2006 |
353 | |
354 | * Moved the code for creating and parsing the gzip extra field into |
355 | IO::Compress::Zlib::Extra.pm so that IO::Compress::Zip & |
356 | IO::Uncompress::Unzip can use it as well. |
357 | |
358 | * Added ExtraFieldLocal & ExtraFieldCentral options to IO::Compress::Zip. |
359 | These allow the creation of user-defined extra fields in the local |
360 | and central headers, just like the ExtraField option in |
361 | IO::Compress::Gzip. |
362 | |
363 | * Moved the zip constants into IO::Compress::Zip::Constants |
364 | |
365 | * Added exTime option to IO::Compress::Zip. |
366 | This allows creation of the extended timestamp extra field. |
367 | |
368 | * Added Minimal option to IO::Compress::Zip. |
369 | This disables the creation of all extended fields. |
370 | |
371 | * Added TextFlag option to IO::Compress::Zip. |
372 | |
373 | * Documented Comment and ZipComment options in IO::Compress::Zip. |
374 | |
375 | * Compress::Zlib |
376 | Fixed gzread to zap the output buffer to an empty string when zero |
377 | bytes are requested. This matches the behaviour of C::Z 1.x |
378 | |
379 | 2.000_11 10 April 2006 |
380 | |
381 | * Transparent + InputLength made more robust where input data is not |
382 | compressed. |
383 | |
384 | * Updated Documentation for zip modules. |
385 | |
386 | * Changed IO::Compress::Zip 'Store' option to 'Method' and added |
387 | symbolic constants ZIP_CM_STORE, ZIP_CM_DEFLATE and ZIP_CM_BZIP2 to |
388 | allow the compression method to be picked by the user. |
389 | |
390 | * Added support to allow bzip2 compressed data to be written/read |
391 | with IO::Compress::Zip and IO::Uncompress::Unzip. |
392 | |
393 | * Beefed up 050interop-gzip.t to check that the external gzip command |
394 | works as expected before starting the tests. This means that |
395 | this test harness will just be skipped on problematic systems. |
396 | |
397 | * Merged core patch 27565 from Steve Peters. This works around a |
398 | problem with gzip on OpenBSD where it doesn't seem to like |
399 | compressing files < 10 bytes long. |
400 | |
401 | * Beefed up 050interop-bzip2.t to check that the external bzip2 command |
402 | works as expected before starting the tests. This means that |
403 | this test harness will just be skipped on problematic systems. |
404 | |
405 | 2.000_10 13 March 2006 |
406 | |
407 | * AnyUncompress doesn't assume that IO-Compress-Zlib is installed any |
408 | more. |
409 | |
410 | * Documentation updates. |
411 | |
412 | * Compress::Zlib |
413 | Changed gzread so that its behaviour matches C::Z::gzread 1.x if it |
414 | is called after eof. In this case it will write an empty string |
415 | into the output parameter. This change is solely for backward |
416 | compatability reasons. |
417 | |
418 | 2.000_09 3 March 2006 |
419 | |
420 | * Released to CPAN. |
421 | |
422 | 2.000_08 2 March 2006 |
423 | |
424 | * Split IO::Compress::Base into its own distribution. |
425 | |
426 | * Split IO::Compress::Bzip2 into its own distribution. |
427 | |
428 | * Added opened, autoflush and input_line_number. |
429 | |
430 | * Beefed up support for $. |
431 | |
432 | * Split IO::Compress::Zlib into its own distribution. |
433 | |
434 | * Beefed up support for zip/unzip |
435 | |
436 | * Breakout zlib specific code into separate modules. |
437 | |
438 | * Limited support for reading/writing zip files |
439 | |
440 | 2.000_06 5 October 2005 |
441 | |
442 | * Added eof parameter to Compress::Zlib::inflate method. |
443 | |
444 | * Fixed issue with 64-bit |
445 | |
446 | 2.000_05 4 October 2005 |
447 | |
448 | * Renamed IO::* to IO::Compress::* & IO::Uncompress::* |
449 | |
450 | 2.000_04 23 September 2005 |
451 | |
452 | * Fixed some more non-portable test that were failing on VMS. |
453 | |
454 | * fixed problem where error messages in the oneshot interface were |
455 | getting lost. |
456 | |
457 | 2.000_03 12 September 2005 |
458 | |
459 | * Fixed some non-portable test that were failing on VMS. |

464 | |
465 | * Split Append mode into Append and Merge |
466 | |

476 | |
477 | * Fixed VERSION in Compress::Gzip::Constants |
478 | |
479 | * Removed Compress::Gzip::Info from the distribution. |

524 | * Integrate core change 24788 - Makefile.PL adjustments for the core |
525 | |
526 | |
527 | 1.34 - 30 January 2005 |
528 | |
529 | * Fixed typo in the README |
530 | |
531 | * Fixed examples.t on Win32 where paths have embedded whitespace. |
532 | |
533 | * Fix for Cygwin and core integration from Jos I. Boumans |
534 | |
535 | * Upgrade zlib source to 1.2.2 |
536 | |
537 | 1.33 - 14 January 2004 |
538 | |
539 | * Reworked Makefile.PL to avoid creating a private copy of zlib. |
540 | This both simplifies the build, plus it makes life easier for VMS. |
541 | |
542 | * Patches for Makefile.PL to get it to work on VMS supplied by |
543 | Craig A. Berry. |
544 | |
545 | * memGunzip has very slow on FreeBSD. Turns out to be down to |
546 | the way realloc works on FreeBSD. Changed both inflate & deflate |
547 | to use exponentially increasing buffer sizes when they need to |
548 | realloc. Thanks to Peter Jeremy for the lowdown on FreeBSD |
549 | memory allocation. |
550 | |
551 | 1.32 - 26 November 2003 |
552 | |
553 | * Steve Hay reported a problem on rt.cpan.org with Windows and |
554 | MSCV++ 6.0 where the source from the zlib directory was getting |
555 | installed with the rest of the module. |
556 | https://rt.cpan.org/Ticket/Display.html?id=1741 |
557 | |
558 | This has been fixed by renaming the "zlib" directory to "zlib-src" |
559 | thus avoiding a conflict with the name of this Perl module. |
560 | |
561 | * Fixed a bug in the inflate method where the input buffer is an |
562 | lvalue (via substr). Problem & solution reported by Salvador Fandiqo. |
563 | |
564 | * Tightened up the logic in Makefile.PL when BUILD_ZLIB is |
565 | True. Issue spotted by Ralf S. Engelschall. |
566 | |
567 | 1.31 - 29 October 2003 |
568 | |
569 | * Reinstated the creation of .bak files - $^I seems to need a |
570 | backup file on Windows. For OpenVMS, the extenstion _bak is used. |
571 | |
572 | 1.30 - 28 October 2003 |
573 | |
574 | * Bundled a sub-set of the zlib source with the module and changed |
575 | the default make behaviour to build with the included zlib source. |
576 | The previous behaviour of using a pre-built zlib library is |
577 | still available for those that want it. |
578 | |
579 | * Added prototypes to the subs in Zlib.pm that didn't already have |
580 | them. Patch from Ed Avis. |
581 | |
582 | * No .bak files are created by Makefile.PL any more - this keep |
583 | distclean much happier. Patch suggested by Ed Avis. |
584 | This also fixes a similar problem reported by Dr. Martin Zinser |
585 | on OpenVMS. |
586 | |
587 | * Documentation for some of the gz functions updated. |
588 | |
589 | * Format strings modified in DispStream to keep OpenVMS happy. |
590 | Problem reported by Dr. Martin Zinser. |
591 | |
592 | |
593 | 1.22 - 17 June 2003 |
594 | |
595 | * Makefile.PL now displays a warning about not installing |
596 | Compress::Zlib via the CPAN shell. |
597 | |
598 | * Fix to allow intermingling of gzread & gzreadline - patch |
599 | supplied by Doug Perham. |
600 | |
601 | * memGunzip will silently now work if the gzip trailer is |
602 | missing. Some HTTP Origin Servers seem to leave it out. |
603 | |
604 | 1.21 - 28 April 2003 |
605 | |
606 | * Tests 148 & 150 from t/02zlib.t were failing on redhat 9. |
607 | |
608 | * Added a few words about the problems with Mac OS X to the README file. |
609 | |
610 | 1.20 - 4 April 2003 |
611 | |
612 | * Fixed bug in gzopen where $gzerrno wasn't being set correctly. |
613 | The symptom was $gzerrno was set to Z_MEM_ERROR although the file |
614 | was opened ok. If gzopen failed, $gzerrno was being set correctly. |
615 | This problem wasn't spotted before because the typical test |
616 | to determine whether gzopen passed or failed was to check its |
617 | return value. |
618 | |
619 | 1.19 - 31 October 2002 |
620 | |
621 | * fixed a problem with t/02zlib.t that was failing with redhat 8. |
622 | |
623 | 1.18 - 24 October 2002 |
624 | |
625 | * fixed a Win32 problem in t/02zlib.t by changing sysread to read. |
626 | |
627 | * zlib 1.0.5 & older doesn't have gzsetparams & gzeof. Added a new |
628 | variable to config.in to flag an old version of zlib. Split |
629 | out the tests for gzsetparams into t/05gzsetp.t |
630 | |
631 | 1.17 - 23 May 2002 |
632 | |
633 | * Moved the test to check the versions of libz & zlib.h into a separate |
634 | file and added troubleshooting notes to README. |
635 | |
636 | * In gzopen, only attempt to call "tell" for normal files. |
637 | |
638 | * Fixed to work in taint mode. |
639 | |
640 | * Broke changes out of README into Changes file. |
641 | |
642 | * Replaced internal use of Z_PARTIAL_FLUSH symbol with Z_SYNC_FLUSH. |
643 | zlib.h says /* will be removed, use Z_SYNC_FLUSH instead */ |
644 | |
645 | 1.16 - 13 December 2001 |
646 | |
647 | * Fixed bug in Makefile.PL that stopped "perl Makefile.PL PREFIX=..." |
648 | working. |
649 | |
650 | 1.15 - 4th December 2001 |
651 | |
652 | * Changes a few types to get the module to build on 64-bit Solaris |
653 | |
654 | * Changed the up/downgrade logic to default to the older constructs, and |
655 | to only call a downgrade if specifically requested. Some older versions |
656 | of Perl were having problems with the in-place edit. |
657 | |
658 | * added the new XS constant code. |
659 | |
660 | 1.14 - 27th August 2001 |
661 | |
662 | * Memory overwrite bug fixed in "inflate". Kudos to Rob Simons for |
663 | reporting the bug and to Anton Berezin for fixing it for me. |
664 | |
665 | 1.13 - 31st June 2001 |
666 | |
667 | * Make sure config.in is consistant when released. |
668 | |
669 | 1.12 - 28th April 2001 |
670 | |
671 | * Modified Makefile.PL to only enable the warnings pragma if |
672 | using perl 5.6.1 or better. |
673 | |
674 | 1.11 - 17th February 2001 |
675 | |
676 | * Added logic in Makefile.PL to toggle between using $^W and |
677 | the warnings pragma in the module. |
678 | |
679 | * The module, the examples & the test harness are now all strict |
680 | & warnings clean. |
681 | |
682 | 1.10 - 5th February 2001 |
683 | |
684 | * fixed a bug in memGunzip. Used Z_ERR instead of Z_DATA_ERROR. |
685 | |
686 | 1.09 - 15th January 2001 |
687 | |
688 | * Silenced a few compiler warnings. |
689 | |
690 | * Updated zlib home site in README & Zlib.pm to www.info-zip.org |
691 | |
692 | * Minor typo in Zlib.pm - a link used AUTHORS instead of AUTHOR |
693 | -- spotted by Frank Martini. |
694 | |
695 | * Mention Archive::Zip |
696 | |
697 | * added memGunzip. This is largely based on code provided by Jim Leonard. |
698 | |
699 | * $deflate->flush can now take an optional parameter. Valid |
700 | values are Z_NO_FLUSH, Z_PARTIAL_FLUSH, Z_SYNC_FLUSH, Z_FULL_FLUSH |
701 | and Z_FINISH. The default is Z_FINISH. |
702 | |
703 | 1.08 - 6 Jan 2000 |
704 | |
705 | * uncompress was clobbering its input parameter. Now it doesn't. |
706 | This bug was spotted by Deven T. Corzine. |
707 | |
708 | * If a variable that only ever contained a number was given |
709 | to compress or deflate, it would not be compressed properly. Now |
710 | it will be coerced to a string and then compressed. This bug |
711 | was spotted by Deven T. Corzine. |
712 | |
713 | 1.07 - 27 Nov 1999 |
714 | |
715 | * ANSI-ified the static functions in Zlib.xs |
716 | |
717 | * Added the ability to build zlib along with the module. |
718 | This feature is 90% based on a Makefile provided by Gurusamy |
719 | Sarathy. |
720 | |
721 | 1.06 - 20 Sep 1999 |
722 | |
723 | * Fixed a nasty problem where inflate could truncate the data |
724 | returned. Thanks to Douglas Thomson <dougt@mugc.cc.monash.edu.au> |
725 | for both spotting the problem and fixing the bug. |
726 | |
727 | * Added a note about the undocumented features in zlib that are |
728 | required when accessing zip files. |
729 | |
730 | * gzclose will now get called automatically when the gzip object is |
731 | destroyed. |
732 | |
733 | 1.05 - 3 June 1999 |
734 | |
735 | * Previous release used newSVpvn, which doesn't exist in 5.004_04 |
736 | or earlier. Changed to use newSVpv instead. |
737 | |
738 | * The module needs Perl 5.004 or better, so updated the version |
739 | checking in Zlib.pm and Makefile.PL |
740 | |
741 | 1.04 - 27 May 1999 |
742 | |
743 | * Bug 19990527.001: compress(undef) core dumps -- Fixed. |
744 | |
745 | 1.03 - 17 Mar 1999 |
746 | |
747 | * Updated to use the new PL_ symbols. |
748 | Means the module can be built with Perl 5.005_5* |
749 | |
750 | 1.02 - 31 Jan 1999 |
751 | |
752 | * The return codes for gzread, gzreadline and gzwrite were |
753 | documented incorrectly as returning a status code. |
754 | |
755 | * The test harness was missing a "gzclose". This caused problem |
756 | showed up on an amiga. Thanks to Erik van Roode for reporting |
757 | this one. |
758 | |
759 | * Patched zlib.t for OS/2. Thanks to Ilya Zakharevich for the patch. |
760 | |
761 | 1.01 - 23 Nov 1997 |
762 | |
763 | * A number of fixes to the test suite and the example scripts to |
764 | allow them to work under win32. All courtesy of Gurusamy |
765 | Sarathy. |
766 | |
767 | 1.00 - 14 Nov 1997 |
768 | |
769 | * Fixed crc32 & adler32. They were very broken. |
770 | |
771 | * The following functions can now take a scalar reference in |
772 | place of a scalar for their buffer parameters: |
773 | |
774 | compress |
775 | uncompress |
776 | deflate |
777 | inflate |
778 | crc32 |
779 | adler32 |
780 | |
781 | This should mean applications that make use of the module don't |
782 | have to copy large buffers around. |
783 | |
784 | |
785 | * Normally the inflate method consumes I<all> of the input buffer |
786 | before returning. The exception to this is when inflate detects |
787 | the end of the stream (Z_STREAM_END). In this case the input |
788 | buffer need not be completely consumed. To allow processing of |
789 | file formats that embed a deflation stream (e.g. zip, gzip), |
790 | the inflate method now sets the buffer parameter to be what |
791 | remains after inflation. |
792 | |
793 | When the return status is Z_STREAM_END, it will be what remains |
794 | of the buffer (if any) after deflation. When the status is Z_OK |
795 | it will be an empty string. |
796 | |
797 | This change means that the buffer parameter must be a lvalue. |
798 | |
799 | * Fixed crc32 and adler32. They were both very broken. |
800 | |
801 | * Added the Compress::Zlib::memGzip function. |
802 | |
803 | 0.5 - Confirmed that no changes were necessary for zlib 1.0.3, or 1.0.4. |
804 | |
805 | The optional parameters for deflateInit and inflateInit can now |
806 | be specified as an associative array in addition to a reference |
807 | to an associative array. They can also accept the -Name |
808 | syntax. |
809 | |
810 | gzopen can now optionally take a reference to an open |
811 | filehandle in place of a filename. In this case it will call |
812 | gzdopen. |
813 | |
814 | Added gzstream example script. |
815 | |
816 | 0.4 - Upgrade to support zlib 0.99 |
817 | |
818 | Added dictionary interface. |
819 | |
820 | Fixed bug in gzreadline - previously it would keep returning |
821 | the same buffer. This bug was reported by Helmut Jarausch |
822 | |
823 | Removed dependency to zutil.h and so dropped support for |
824 | |
825 | DEF_MEM_LEVEL (use MAX_MEM_LEVEL instead) |
826 | DEF_WBITS (use MAX_WBITS instead) |
827 | |
828 | 0.3 - Added prototype specification. |
829 | |
830 | 0.2 - Fixed a minor allocation problem in Zlib.xs |
831 | |
832 | 0.1 - first alpha release. 2nd October 1995 |
