53 * Removed Compress::Gzip::Info from the distribution.
55 2.000_00 21 August 2005
57 * First Beta relase of Compress::zlib rewrite.
59 1.38 - 6 September 2005
61 * Integrate core change 25304 -- Symbian Update
63 * Added libscan to Makefile.PL
67 * Change to t/03examples.t for VMS from Abe Timmerman
71 * Renamed zlib-src-1.2.3 to zlib-src to help VMS
73 * Fixed Makefile.PL for VMS
75 * Fixed t/03examples.t for VMS
77 * Added a couple of notes about incompatibility with Unix compress.
81 * Updated zlib source to 1.2.3
83 * Fixed problem with where two calls to gzclose would hang the debugger.
84 See https://rt.cpan.org/Ticket/Display.html?id=13789
86 * Added code from Alexey Tourbin to use XSLoader when available,
87 and DynaLoader otherwise.
89 * Documented that the compress & uncompress functions were not
90 the same as the Unix utilities of the same name.
92 * Fixed 05gzsetp -- it left a temp file hanging around.
94 * Integrate core change 24787 - SvUPGRADE returns void in blead
96 * Integrate core change 24788 - Makefile.PL adjustments for the core
99 1.34 - 30 January 2005
101 * Fixed typo in the README
103 * Fixed examples.t on Win32 where paths have embedded whitespace.
105 * Fix for Cygwin and core integration from Jos I. Boumans
107 * Upgrade zlib source to 1.2.2
109 1.33 - 14 January 2004
111 * Reworked Makefile.PL to avoid creating a private copy of zlib.
112 This both simplifies the build, plus it makes life easier for VMS.
114 * Patches for Makefile.PL to get it to work on VMS supplied by
117 * memGunzip has very slow on FreeBSD. Turns out to be down to
118 the way realloc works on FreeBSD. Changed both inflate & deflate
119 to use exponentially increasing buffer sizes when they need to
120 realloc. Thanks to Peter Jeremy for the lowdown on FreeBSD
123 1.32 - 26 November 2003
125 * Steve Hay reported a problem on rt.cpan.org with Windows and
126 MSCV++ 6.0 where the source from the zlib directory was getting
127 installed with the rest of the module.
128 https://rt.cpan.org/Ticket/Display.html?id=1741
130 This has been fixed by renaming the "zlib" directory to "zlib-src"
131 thus avoiding a conflict with the name of this Perl module.
133 * Fixed a bug in the inflate method where the input buffer is an
134 lvalue (via substr). Problem & solution reported by Salvador Fandiqo.
136 * Tightened up the logic in Makefile.PL when BUILD_ZLIB is
137 True. Issue spotted by Ralf S. Engelschall.
139 1.31 - 29 October 2003
141 * Reinstated the creation of .bak files - $^I seems to need a
142 backup file on Windows. For OpenVMS, the extenstion _bak is used.
144 1.30 - 28 October 2003
146 * Bundled a sub-set of the zlib source with the module and changed
147 the default make behaviour to build with the included zlib source.
148 The previous behaviour of using a pre-built zlib library is
149 still available for those that want it.
151 * Added prototypes to the subs in Zlib.pm that didn't already have
152 them. Patch from Ed Avis.
154 * No .bak files are created by Makefile.PL any more - this keep
155 distclean much happier. Patch suggested by Ed Avis.
156 This also fixes a similar problem reported by Dr. Martin Zinser
159 * Documentation for some of the gz functions updated.
161 * Format strings modified in DispStream to keep OpenVMS happy.
162 Problem reported by Dr. Martin Zinser.
167 * Makefile.PL now displays a warning about not installing
168 Compress::Zlib via the CPAN shell.
170 * Fix to allow intermingling of gzread & gzreadline - patch
171 supplied by Doug Perham.
173 * memGunzip will silently now work if the gzip trailer is
174 missing. Some HTTP Origin Servers seem to leave it out.
178 * Tests 148 & 150 from t/02zlib.t were failing on redhat 9.
180 * Added a few words about the problems with Mac OS X to the README file.
184 * Fixed bug in gzopen where $gzerrno wasn't being set correctly.
185 The symptom was $gzerrno was set to Z_MEM_ERROR although the file
186 was opened ok. If gzopen failed, $gzerrno was being set correctly.
187 This problem wasn't spotted before because the typical test
188 to determine whether gzopen passed or failed was to check its
191 1.19 - 31 October 2002
193 * fixed a problem with t/02zlib.t that was failing with redhat 8.
195 1.18 - 24 October 2002
197 * fixed a Win32 problem in t/02zlib.t by changing sysread to read.
199 * zlib 1.0.5 & older doesn't have gzsetparams & gzeof. Added a new
200 variable to config.in to flag an old version of zlib. Split
201 out the tests for gzsetparams into t/05gzsetp.t
205 * Moved the test to check the versions of libz & zlib.h into a separate
206 file and added troubleshooting notes to README.
208 * In gzopen, only attempt to call "tell" for normal files.
210 * Fixed to work in taint mode.
212 * Broke changes out of README into Changes file.
214 * Replaced internal use of Z_PARTIAL_FLUSH symbol with Z_SYNC_FLUSH.
215 zlib.h says /* will be removed, use Z_SYNC_FLUSH instead */
217 1.16 - 13 December 2001
219 * Fixed bug in Makefile.PL that stopped "perl Makefile.PL PREFIX=..."
222 1.15 - 4th December 2001
224 * Changes a few types to get the module to build on 64-bit Solaris
226 * Changed the up/downgrade logic to default to the older constructs, and
227 to only call a downgrade if specifically requested. Some older versions
228 of Perl were having problems with the in-place edit.
230 * added the new XS constant code.
232 1.14 - 27th August 2001
234 * Memory overwrite bug fixed in "inflate". Kudos to Rob Simons for
235 reporting the bug and to Anton Berezin for fixing it for me.
237 1.13 - 31st June 2001
239 * Make sure config.in is consistant when released.
241 1.12 - 28th April 2001
243 * Modified Makefile.PL to only enable the warnings pragma if
244 using perl 5.6.1 or better.
246 1.11 - 17th February 2001
248 * Added logic in Makefile.PL to toggle between using $^W and
249 the warnings pragma in the module.
251 * The module, the examples & the test harness are now all strict
254 1.10 - 5th February 2001
256 * fixed a bug in memGunzip. Used Z_ERR instead of Z_DATA_ERROR.
258 1.09 - 15th January 2001
260 * Silenced a few compiler warnings.
262 * Updated zlib home site in README & Zlib.pm to www.info-zip.org
264 * Minor typo in Zlib.pm - a link used AUTHORS instead of AUTHOR
265 -- spotted by Frank Martini.
267 * Mention Archive::Zip
269 * added memGunzip. This is largely based on code provided by Jim Leonard.
271 * $deflate->flush can now take an optional parameter. Valid
272 values are Z_NO_FLUSH, Z_PARTIAL_FLUSH, Z_SYNC_FLUSH, Z_FULL_FLUSH
273 and Z_FINISH. The default is Z_FINISH.
277 * uncompress was clobbering its input parameter. Now it doesn't.
278 This bug was spotted by Deven T. Corzine.
280 * If a variable that only ever contained a number was given
281 to compress or deflate, it would not be compressed properly. Now
282 it will be coerced to a string and then compressed. This bug
283 was spotted by Deven T. Corzine.
287 * ANSI-ified the static functions in Zlib.xs
289 * Added the ability to build zlib along with the module.
290 This feature is 90% based on a Makefile provided by Gurusamy
295 * Fixed a nasty problem where inflate could truncate the data
296 returned. Thanks to Douglas Thomson <dougt@mugc.cc.monash.edu.au>
297 for both spotting the problem and fixing the bug.
299 * Added a note about the undocumented features in zlib that are
300 required when accessing zip files.
302 * gzclose will now get called automatically when the gzip object is
307 * Previous release used newSVpvn, which doesn't exist in 5.004_04
308 or earlier. Changed to use newSVpv instead.
310 * The module needs Perl 5.004 or better, so updated the version
311 checking in Zlib.pm and Makefile.PL
315 * Bug 19990527.001: compress(undef) core dumps -- Fixed.
319 * Updated to use the new PL_ symbols.
320 Means the module can be built with Perl 5.005_5*
324 * The return codes for gzread, gzreadline and gzwrite were
325 documented incorrectly as returning a status code.
327 * The test harness was missing a "gzclose". This caused problem
328 showed up on an amiga. Thanks to Erik van Roode for reporting
331 * Patched zlib.t for OS/2. Thanks to Ilya Zakharevich for the patch.
335 * A number of fixes to the test suite and the example scripts to
336 allow them to work under win32. All courtesy of Gurusamy
341 * Fixed crc32 & adler32. They were very broken.
343 * The following functions can now take a scalar reference in
344 place of a scalar for their buffer parameters:
353 This should mean applications that make use of the module don't
354 have to copy large buffers around.
357 * Normally the inflate method consumes I<all> of the input buffer
358 before returning. The exception to this is when inflate detects
359 the end of the stream (Z_STREAM_END). In this case the input
360 buffer need not be completely consumed. To allow processing of
361 file formats that embed a deflation stream (e.g. zip, gzip),
362 the inflate method now sets the buffer parameter to be what
363 remains after inflation.
365 When the return status is Z_STREAM_END, it will be what remains
366 of the buffer (if any) after deflation. When the status is Z_OK
367 it will be an empty string.
369 This change means that the buffer parameter must be a lvalue.
371 * Fixed crc32 and adler32. They were both very broken.
373 * Added the Compress::Zlib::memGzip function.
375 0.5 - Confirmed that no changes were necessary for zlib 1.0.3, or 1.0.4.
377 The optional parameters for deflateInit and inflateInit can now
378 be specified as an associative array in addition to a reference
379 to an associative array. They can also accept the -Name
382 gzopen can now optionally take a reference to an open
383 filehandle in place of a filename. In this case it will call
386 Added gzstream example script.
388 0.4 - Upgrade to support zlib 0.99
390 Added dictionary interface.
392 Fixed bug in gzreadline - previously it would keep returning
393 the same buffer. This bug was reported by Helmut Jarausch
395 Removed dependency to zutil.h and so dropped support for
397 DEF_MEM_LEVEL (use MAX_MEM_LEVEL instead)
398 DEF_WBITS (use MAX_WBITS instead)
400 0.3 - Added prototype specification.
402 0.2 - Fixed a minor allocation problem in Zlib.xs
404 0.1 - first alpha release. 2nd October 1995
