4 1.40 - 23 September 2005
6 * Fixed failure of 03examples.t for some windows systems.
8 1.39 - 15 September 2005
10 * Fixed dTHX macro for 5.00503 on FreeBSD
12 1.38 - 6 September 2005
14 * Integrate core change 25304 -- Symbian Update
16 * Added libscan to Makefile.PL
20 * Change to t/03examples.t for VMS from Abe Timmerman
24 * Renamed zlib-src-1.2.3 to zlib-src to help VMS
26 * Fixed Makefile.PL for VMS
28 * Fixed t/03examples.t for VMS
30 * Added a couple of notes about incompatibility with Unix compress.
34 * Updated zlib source to 1.2.3
36 * Fixed problem with where two calls to gzclose would hang the debugger.
37 See https://rt.cpan.org/Ticket/Display.html?id=13789
39 * Added code from Alexey Tourbin to use XSLoader when available,
40 and DynaLoader otherwise.
42 * Documented that the compress & uncompress functions were not
43 the same as the Unix utilities of the same name.
45 * Fixed 05gzsetp -- it left a temp file hanging around.
47 * Integrate core change 24787 - SvUPGRADE returns void in blead
49 * Integrate core change 24788 - Makefile.PL adjustments for the core
52 1.34 - 30 January 2005
54 * Fixed typo in the README
56 * Fixed examples.t on Win32 where paths have embedded whitespace.
58 * Fix for Cygwin and core integration from Jos I. Boumans
60 * Upgrade zlib source to 1.2.2
62 1.33 - 14 January 2004
64 * Reworked Makefile.PL to avoid creating a private copy of zlib.
65 This both simplifies the build, plus it makes life easier for VMS.
67 * Patches for Makefile.PL to get it to work on VMS supplied by
70 * memGunzip has very slow on FreeBSD. Turns out to be down to
71 the way realloc works on FreeBSD. Changed both inflate & deflate
72 to use exponentially increasing buffer sizes when they need to
73 realloc. Thanks to Peter Jeremy for the lowdown on FreeBSD
76 1.32 - 26 November 2003
78 * Steve Hay reported a problem on rt.cpan.org with Windows and
79 MSCV++ 6.0 where the source from the zlib directory was getting
80 installed with the rest of the module.
81 https://rt.cpan.org/Ticket/Display.html?id=1741
83 This has been fixed by renaming the "zlib" directory to "zlib-src"
84 thus avoiding a conflict with the name of this Perl module.
86 * Fixed a bug in the inflate method where the input buffer is an
87 lvalue (via substr). Problem & solution reported by Salvador Fandiqo.
89 * Tightened up the logic in Makefile.PL when BUILD_ZLIB is
90 True. Issue spotted by Ralf S. Engelschall.
92 1.31 - 29 October 2003
94 * Reinstated the creation of .bak files - $^I seems to need a
95 backup file on Windows. For OpenVMS, the extension _bak is used.
97 1.30 - 28 October 2003
99 * Bundled a sub-set of the zlib source with the module and changed
100 the default make behaviour to build with the included zlib source.
101 The previous behaviour of using a pre-built zlib library is
102 still available for those that want it.
104 * Added prototypes to the subs in Zlib.pm that didn't already have
105 them. Patch from Ed Avis.
107 * No .bak files are created by Makefile.PL any more - this keep
108 distclean much happier. Patch suggested by Ed Avis.
109 This also fixes a similar problem reported by Dr. Martin Zinser
112 * Documentation for some of the gz functions updated.
114 * Format strings modified in DispStream to keep OpenVMS happy.
115 Problem reported by Dr. Martin Zinser.
120 * Makefile.PL now displays a warning about not installing
121 Compress::Zlib via the CPAN shell.
123 * Fix to allow intermingling of gzread & gzreadline - patch
124 supplied by Doug Perham.
126 * memGunzip will silently now work if the gzip trailer is
127 missing. Some HTTP Origin Servers seem to leave it out.
131 * Tests 148 & 150 from t/02zlib.t were failing on redhat 9.
133 * Added a few words about the problems with Mac OS X to the README file.
137 * Fixed bug in gzopen where $gzerrno wasn't being set correctly.
138 The symptom was $gzerrno was set to Z_MEM_ERROR although the file
139 was opened ok. If gzopen failed, $gzerrno was being set correctly.
140 This problem wasn't spotted before because the typical test
141 to determine whether gzopen passed or failed was to check its
144 1.19 - 31 October 2002
146 * fixed a problem with t/02zlib.t that was failing with redhat 8.
148 1.18 - 24 October 2002
150 * fixed a Win32 problem in t/02zlib.t by changing sysread to read.
152 * zlib 1.0.5 & older doesn't have gzsetparams & gzeof. Added a new
153 variable to config.in to flag an old version of zlib. Split
154 out the tests for gzsetparams into t/05gzsetp.t
156 1.17 - 22 October 2002
158 * Moved the test to check the versions of libz & zlib.h into a separate
159 file and added troubleshooting notes to README.
161 * In gzopen, only attempt to call "tell" for normal files.
163 * Broke changes out of README into Changes file.
165 * Replaced internal use of Z_PARTIAL_FLUSH symbol with Z_SYNC_FLUSH.
166 zlib.h says /* will be removed, use Z_SYNC_FLUSH instead */
168 * Added support for zlib functions inflateSync and deflateParams.
170 * Added support for zlib functions gzeof and gzsetparams.
172 * Added support for access to adler, total_in & total_out
174 * The compress function can now take an optional parameter that
175 allows the compression level to be specified. This mirrors the
176 compress2 function available in zlib.
178 * memGzip doesn't work properly with perl 5.8.0 when it is given
179 UTF-8 data. Bug spotted by Andreas J. Koenig.
181 * Added note about Linux zlib-devel RPM to README.
183 * Fixed recursive build problem on win32 machines.
185 * Fixed problem with the test harness on Mac OS X.
186 Thanks to Carl Johan Berglund for reporting the problem and
187 helping track it down.
190 1.16 - 13 December 2001
192 * Fixed bug in Makefile.PL that stopped "perl Makefile.PL PREFIX=..."
195 1.15 - 4th December 2001
197 * Changes a few types to get the module to build on 64-bit Solaris
199 * Changed the up/downgrade logic to default to the older constructs, and
200 to only call a downgrade if specifically requested. Some older versions
201 of Perl were having problems with the in-place edit.
203 * added the new XS constant code.
205 1.14 - 27th August 2001
207 * Memory overwrite bug fixed in "inflate". Kudos to Rob Simons for
208 reporting the bug and to Anton Berezin for fixing it for me.
210 1.13 - 31st June 2001
212 * Make sure config.in is consistent when released.
214 1.12 - 28th April 2001
216 * Modified Makefile.PL to only enable the warnings pragma if
217 using perl 5.6.1 or better.
219 1.11 - 17th February 2001
221 * Added logic in Makefile.PL to toggle between using $^W and
222 the warnings pragma in the module.
224 * The module, the examples & the test harness are now all strict
227 1.10 - 5th February 2001
229 * fixed a bug in memGunzip. Used Z_ERR instead of Z_DATA_ERROR.
231 1.09 - 15th January 2001
233 * Silenced a few compiler warnings.
235 * Updated zlib home site in README & Zlib.pm to www.info-zip.org
237 * Minor typo in Zlib.pm - a link used AUTHORS instead of AUTHOR
238 -- spotted by Frank Martini.
240 * Mention Archive::Zip
242 * added memGunzip. This is largely based on code provided by Jim Leonard.
244 * $deflate->flush can now take an optional parameter. Valid
245 values are Z_NO_FLUSH, Z_PARTIAL_FLUSH, Z_SYNC_FLUSH, Z_FULL_FLUSH
246 and Z_FINISH. The default is Z_FINISH.
250 * uncompress was clobbering its input parameter. Now it doesn't.
251 This bug was spotted by Deven T. Corzine.
253 * If a variable that only ever contained a number was given
254 to compress or deflate, it would not be compressed properly. Now
255 it will be coerced to a string and then compressed. This bug
256 was spotted by Deven T. Corzine.
260 * ANSI-ified the static functions in Zlib.xs
262 * Added the ability to build zlib along with the module.
263 This feature is 90% based on a Makefile provided by Gurusamy
268 * Fixed a nasty problem where inflate could truncate the data
269 returned. Thanks to Douglas Thomson <dougt@mugc.cc.monash.edu.au>
270 for both spotting the problem and fixing the bug.
272 * Added a note about the undocumented features in zlib that are
273 required when accessing zip files.
275 * gzclose will now get called automatically when the gzip object is
280 * Previous release used newSVpvn, which doesn't exist in 5.004_04
281 or earlier. Changed to use newSVpv instead.
283 * The module needs Perl 5.004 or better, so updated the version
284 checking in Zlib.pm and Makefile.PL
288 * Bug 19990527.001: compress(undef) core dumps -- Fixed.
292 * Updated to use the new PL_ symbols.
293 Means the module can be built with Perl 5.005_5*
297 * The return codes for gzread, gzreadline and gzwrite were
298 documented incorrectly as returning a status code.
300 * The test harness was missing a "gzclose". This caused problem
301 showed up on an amiga. Thanks to Erik van Roode for reporting
304 * Patched zlib.t for OS/2. Thanks to Ilya Zakharevich for the patch.
308 * A number of fixes to the test suite and the example scripts to
309 allow them to work under win32. All courtesy of Gurusamy
314 * Fixed crc32 & adler32. They were very broken.
316 * The following functions can now take a scalar reference in
317 place of a scalar for their buffer parameters:
326 This should mean applications that make use of the module don't
327 have to copy large buffers around.
330 * Normally the inflate method consumes I<all> of the input buffer
331 before returning. The exception to this is when inflate detects
332 the end of the stream (Z_STREAM_END). In this case the input
333 buffer need not be completely consumed. To allow processing of
334 file formats that embed a deflation stream (e.g. zip, gzip),
335 the inflate method now sets the buffer parameter to be what
336 remains after inflation.
338 When the return status is Z_STREAM_END, it will be what remains
339 of the buffer (if any) after deflation. When the status is Z_OK
340 it will be an empty string.
342 This change means that the buffer parameter must be a lvalue.
344 * Fixed crc32 and adler32. They were both very broken.
346 * Added the Compress::Zlib::memGzip function.
348 0.5 - Confirmed that no changes were necessary for zlib 1.0.3, or 1.0.4.
350 The optional parameters for deflateInit and inflateInit can now
351 be specified as an associative array in addition to a reference
352 to an associative array. They can also accept the -Name
355 gzopen can now optionally take a reference to an open
356 filehandle in place of a filename. In this case it will call
359 Added gzstream example script.
361 0.4 - Upgrade to support zlib 0.99
363 Added dictionary interface.
365 Fixed bug in gzreadline - previously it would keep returning
366 the same buffer. This bug was reported by Helmut Jarausch
368 Removed dependency to zutil.h and so dropped support for
370 DEF_MEM_LEVEL (use MAX_MEM_LEVEL instead)
371 DEF_WBITS (use MAX_WBITS instead)
373 0.3 - Added prototype specification.
375 0.2 - Fixed a minor allocation problem in Zlib.xs
377 0.1 - first alpha release. 2nd October 1995
