49 * Removed Compress::Gzip::Info from the distribution.
51 2.000_00 21 August 2005
53 * First Beta relase of Compress::zlib rewrite.
55 1.38 - 6 September 2005
57 * Integrate core change 25304 -- Symbian Update
59 * Added libscan to Makefile.PL
63 * Change to t/03examples.t for VMS from Abe Timmerman
67 * Renamed zlib-src-1.2.3 to zlib-src to help VMS
69 * Fixed Makefile.PL for VMS
71 * Fixed t/03examples.t for VMS
73 * Added a couple of notes about incompatibility with Unix compress.
77 * Updated zlib source to 1.2.3
79 * Fixed problem with where two calls to gzclose would hang the debugger.
80 See https://rt.cpan.org/Ticket/Display.html?id=13789
82 * Added code from Alexey Tourbin to use XSLoader when available,
83 and DynaLoader otherwise.
85 * Documented that the compress & uncompress functions were not
86 the same as the Unix utilities of the same name.
88 * Fixed 05gzsetp -- it left a temp file hanging around.
90 * Integrate core change 24787 - SvUPGRADE returns void in blead
92 * Integrate core change 24788 - Makefile.PL adjustments for the core
95 1.34 - 30 January 2005
97 * Fixed typo in the README
99 * Fixed examples.t on Win32 where paths have embedded whitespace.
101 * Fix for Cygwin and core integration from Jos I. Boumans
103 * Upgrade zlib source to 1.2.2
105 1.33 - 14 January 2004
107 * Reworked Makefile.PL to avoid creating a private copy of zlib.
108 This both simplifies the build, plus it makes life easier for VMS.
110 * Patches for Makefile.PL to get it to work on VMS supplied by
113 * memGunzip has very slow on FreeBSD. Turns out to be down to
114 the way realloc works on FreeBSD. Changed both inflate & deflate
115 to use exponentially increasing buffer sizes when they need to
116 realloc. Thanks to Peter Jeremy for the lowdown on FreeBSD
119 1.32 - 26 November 2003
121 * Steve Hay reported a problem on rt.cpan.org with Windows and
122 MSCV++ 6.0 where the source from the zlib directory was getting
123 installed with the rest of the module.
124 https://rt.cpan.org/Ticket/Display.html?id=1741
126 This has been fixed by renaming the "zlib" directory to "zlib-src"
127 thus avoiding a conflict with the name of this Perl module.
129 * Fixed a bug in the inflate method where the input buffer is an
130 lvalue (via substr). Problem & solution reported by Salvador Fandiqo.
132 * Tightened up the logic in Makefile.PL when BUILD_ZLIB is
133 True. Issue spotted by Ralf S. Engelschall.
135 1.31 - 29 October 2003
137 * Reinstated the creation of .bak files - $^I seems to need a
138 backup file on Windows. For OpenVMS, the extenstion _bak is used.
140 1.30 - 28 October 2003
142 * Bundled a sub-set of the zlib source with the module and changed
143 the default make behaviour to build with the included zlib source.
144 The previous behaviour of using a pre-built zlib library is
145 still available for those that want it.
147 * Added prototypes to the subs in Zlib.pm that didn't already have
148 them. Patch from Ed Avis.
150 * No .bak files are created by Makefile.PL any more - this keep
151 distclean much happier. Patch suggested by Ed Avis.
152 This also fixes a similar problem reported by Dr. Martin Zinser
155 * Documentation for some of the gz functions updated.
157 * Format strings modified in DispStream to keep OpenVMS happy.
158 Problem reported by Dr. Martin Zinser.
163 * Makefile.PL now displays a warning about not installing
164 Compress::Zlib via the CPAN shell.
166 * Fix to allow intermingling of gzread & gzreadline - patch
167 supplied by Doug Perham.
169 * memGunzip will silently now work if the gzip trailer is
170 missing. Some HTTP Origin Servers seem to leave it out.
174 * Tests 148 & 150 from t/02zlib.t were failing on redhat 9.
176 * Added a few words about the problems with Mac OS X to the README file.
180 * Fixed bug in gzopen where $gzerrno wasn't being set correctly.
181 The symptom was $gzerrno was set to Z_MEM_ERROR although the file
182 was opened ok. If gzopen failed, $gzerrno was being set correctly.
183 This problem wasn't spotted before because the typical test
184 to determine whether gzopen passed or failed was to check its
187 1.19 - 31 October 2002
189 * fixed a problem with t/02zlib.t that was failing with redhat 8.
191 1.18 - 24 October 2002
193 * fixed a Win32 problem in t/02zlib.t by changing sysread to read.
195 * zlib 1.0.5 & older doesn't have gzsetparams & gzeof. Added a new
196 variable to config.in to flag an old version of zlib. Split
197 out the tests for gzsetparams into t/05gzsetp.t
201 * Moved the test to check the versions of libz & zlib.h into a separate
202 file and added troubleshooting notes to README.
204 * In gzopen, only attempt to call "tell" for normal files.
206 * Fixed to work in taint mode.
208 * Broke changes out of README into Changes file.
210 * Replaced internal use of Z_PARTIAL_FLUSH symbol with Z_SYNC_FLUSH.
211 zlib.h says /* will be removed, use Z_SYNC_FLUSH instead */
213 1.16 - 13 December 2001
215 * Fixed bug in Makefile.PL that stopped "perl Makefile.PL PREFIX=..."
218 1.15 - 4th December 2001
220 * Changes a few types to get the module to build on 64-bit Solaris
222 * Changed the up/downgrade logic to default to the older constructs, and
223 to only call a downgrade if specifically requested. Some older versions
224 of Perl were having problems with the in-place edit.
226 * added the new XS constant code.
228 1.14 - 27th August 2001
230 * Memory overwrite bug fixed in "inflate". Kudos to Rob Simons for
231 reporting the bug and to Anton Berezin for fixing it for me.
233 1.13 - 31st June 2001
235 * Make sure config.in is consistant when released.
237 1.12 - 28th April 2001
239 * Modified Makefile.PL to only enable the warnings pragma if
240 using perl 5.6.1 or better.
242 1.11 - 17th February 2001
244 * Added logic in Makefile.PL to toggle between using $^W and
245 the warnings pragma in the module.
247 * The module, the examples & the test harness are now all strict
250 1.10 - 5th February 2001
252 * fixed a bug in memGunzip. Used Z_ERR instead of Z_DATA_ERROR.
254 1.09 - 15th January 2001
256 * Silenced a few compiler warnings.
258 * Updated zlib home site in README & Zlib.pm to www.info-zip.org
260 * Minor typo in Zlib.pm - a link used AUTHORS instead of AUTHOR
261 -- spotted by Frank Martini.
263 * Mention Archive::Zip
265 * added memGunzip. This is largely based on code provided by Jim Leonard.
267 * $deflate->flush can now take an optional parameter. Valid
268 values are Z_NO_FLUSH, Z_PARTIAL_FLUSH, Z_SYNC_FLUSH, Z_FULL_FLUSH
269 and Z_FINISH. The default is Z_FINISH.
273 * uncompress was clobbering its input parameter. Now it doesn't.
274 This bug was spotted by Deven T. Corzine.
276 * If a variable that only ever contained a number was given
277 to compress or deflate, it would not be compressed properly. Now
278 it will be coerced to a string and then compressed. This bug
279 was spotted by Deven T. Corzine.
283 * ANSI-ified the static functions in Zlib.xs
285 * Added the ability to build zlib along with the module.
286 This feature is 90% based on a Makefile provided by Gurusamy
291 * Fixed a nasty problem where inflate could truncate the data
292 returned. Thanks to Douglas Thomson <dougt@mugc.cc.monash.edu.au>
293 for both spotting the problem and fixing the bug.
295 * Added a note about the undocumented features in zlib that are
296 required when accessing zip files.
298 * gzclose will now get called automatically when the gzip object is
303 * Previous release used newSVpvn, which doesn't exist in 5.004_04
304 or earlier. Changed to use newSVpv instead.
306 * The module needs Perl 5.004 or better, so updated the version
307 checking in Zlib.pm and Makefile.PL
311 * Bug 19990527.001: compress(undef) core dumps -- Fixed.
315 * Updated to use the new PL_ symbols.
316 Means the module can be built with Perl 5.005_5*
320 * The return codes for gzread, gzreadline and gzwrite were
321 documented incorrectly as returning a status code.
323 * The test harness was missing a "gzclose". This caused problem
324 showed up on an amiga. Thanks to Erik van Roode for reporting
327 * Patched zlib.t for OS/2. Thanks to Ilya Zakharevich for the patch.
331 * A number of fixes to the test suite and the example scripts to
332 allow them to work under win32. All courtesy of Gurusamy
337 * Fixed crc32 & adler32. They were very broken.
339 * The following functions can now take a scalar reference in
340 place of a scalar for their buffer parameters:
349 This should mean applications that make use of the module don't
350 have to copy large buffers around.
353 * Normally the inflate method consumes I<all> of the input buffer
354 before returning. The exception to this is when inflate detects
355 the end of the stream (Z_STREAM_END). In this case the input
356 buffer need not be completely consumed. To allow processing of
357 file formats that embed a deflation stream (e.g. zip, gzip),
358 the inflate method now sets the buffer parameter to be what
359 remains after inflation.
361 When the return status is Z_STREAM_END, it will be what remains
362 of the buffer (if any) after deflation. When the status is Z_OK
363 it will be an empty string.
365 This change means that the buffer parameter must be a lvalue.
367 * Fixed crc32 and adler32. They were both very broken.
369 * Added the Compress::Zlib::memGzip function.
371 0.5 - Confirmed that no changes were necessary for zlib 1.0.3, or 1.0.4.
373 The optional parameters for deflateInit and inflateInit can now
374 be specified as an associative array in addition to a reference
375 to an associative array. They can also accept the -Name
378 gzopen can now optionally take a reference to an open
379 filehandle in place of a filename. In this case it will call
382 Added gzstream example script.
384 0.4 - Upgrade to support zlib 0.99
386 Added dictionary interface.
388 Fixed bug in gzreadline - previously it would keep returning
389 the same buffer. This bug was reported by Helmut Jarausch
391 Removed dependency to zutil.h and so dropped support for
393 DEF_MEM_LEVEL (use MAX_MEM_LEVEL instead)
394 DEF_WBITS (use MAX_WBITS instead)
396 0.3 - Added prototype specification.
398 0.2 - Fixed a minor allocation problem in Zlib.xs
400 0.1 - first alpha release. 2nd October 1995
