6 * Change to t/03examples.t for VMS from Abe Timmerman
10 * Renamed zlib-src-1.2.3 to zlib-src to help VMS
12 * Fixed Makefile.PL for VMS
14 * Fixed t/03examples.t for VMS
16 * Added a couple of notes about incompatibility with Unix compress.
20 * Updated zlib source to 1.2.3
22 * Fixed problem with where two calls to gzclose would hang the debugger.
23 See https://rt.cpan.org/Ticket/Display.html?id=13789
25 * Added code from Alexey Tourbin to use XSLoader when available,
26 and DynaLoader otherwise.
28 * Documented that the compress & uncompress functions were not
29 the same as the Unix utilities of the same name.
31 * Fixed 05gzsetp -- it left a temp file hanging around.
33 * Integrate core change 24787 - SvUPGRADE returns void in blead
35 * Integrate core change 24788 - Makefile.PL adjustments for the core
38 1.34 - 30 January 2005
40 * Fixed typo in the README
42 * Fixed examples.t on Win32 where paths have embedded whitespace.
44 * Fix for Cygwin and core integration from Jos I. Boumans
46 * Upgrade zlib source to 1.2.2
48 1.33 - 14 January 2004
50 * Reworked Makefile.PL to avoid creating a private copy of zlib.
51 This both simplifies the build, plus it makes life easier for VMS.
53 * Patches for Makefile.PL to get it to work on VMS supplied by
56 * memGunzip has very slow on FreeBSD. Turns out to be down to
57 the way realloc works on FreeBSD. Changed both inflate & deflate
58 to use exponentially increasing buffer sizes when they need to
59 realloc. Thanks to Peter Jeremy for the lowdown on FreeBSD
62 1.32 - 26 November 2003
64 * Steve Hay reported a problem on rt.cpan.org with Windows and
65 MSCV++ 6.0 where the source from the zlib directory was getting
66 installed with the rest of the module.
67 https://rt.cpan.org/Ticket/Display.html?id=1741
69 This has been fixed by renaming the "zlib" directory to "zlib-src"
70 thus avoiding a conflict with the name of this Perl module.
72 * Fixed a bug in the inflate method where the input buffer is an
73 lvalue (via substr). Problem & solution reported by Salvador Fandiqo.
75 * Tightened up the logic in Makefile.PL when BUILD_ZLIB is
76 True. Issue spotted by Ralf S. Engelschall.
78 1.31 - 29 October 2003
80 * Reinstated the creation of .bak files - $^I seems to need a
81 backup file on Windows. For OpenVMS, the extension _bak is used.
83 1.30 - 28 October 2003
85 * Bundled a sub-set of the zlib source with the module and changed
86 the default make behaviour to build with the included zlib source.
87 The previous behaviour of using a pre-built zlib library is
88 still available for those that want it.
90 * Added prototypes to the subs in Zlib.pm that didn't already have
91 them. Patch from Ed Avis.
93 * No .bak files are created by Makefile.PL any more - this keep
94 distclean much happier. Patch suggested by Ed Avis.
95 This also fixes a similar problem reported by Dr. Martin Zinser
98 * Documentation for some of the gz functions updated.
100 * Format strings modified in DispStream to keep OpenVMS happy.
101 Problem reported by Dr. Martin Zinser.
106 * Makefile.PL now displays a warning about not installing
107 Compress::Zlib via the CPAN shell.
109 * Fix to allow intermingling of gzread & gzreadline - patch
110 supplied by Doug Perham.
112 * memGunzip will silently now work if the gzip trailer is
113 missing. Some HTTP Origin Servers seem to leave it out.
117 * Tests 148 & 150 from t/02zlib.t were failing on redhat 9.
119 * Added a few words about the problems with Mac OS X to the README file.
123 * Fixed bug in gzopen where $gzerrno wasn't being set correctly.
124 The symptom was $gzerrno was set to Z_MEM_ERROR although the file
125 was opened ok. If gzopen failed, $gzerrno was being set correctly.
126 This problem wasn't spotted before because the typical test
127 to determine whether gzopen passed or failed was to check its
130 1.19 - 31 October 2002
132 * fixed a problem with t/02zlib.t that was failing with redhat 8.
134 1.18 - 24 October 2002
136 * fixed a Win32 problem in t/02zlib.t by changing sysread to read.
138 * zlib 1.0.5 & older doesn't have gzsetparams & gzeof. Added a new
139 variable to config.in to flag an old version of zlib. Split
140 out the tests for gzsetparams into t/05gzsetp.t
142 1.17 - 22 October 2002
144 * Moved the test to check the versions of libz & zlib.h into a separate
145 file and added troubleshooting notes to README.
147 * In gzopen, only attempt to call "tell" for normal files.
149 * Broke changes out of README into Changes file.
151 * Replaced internal use of Z_PARTIAL_FLUSH symbol with Z_SYNC_FLUSH.
152 zlib.h says /* will be removed, use Z_SYNC_FLUSH instead */
154 * Added support for zlib functions inflateSync and deflateParams.
156 * Added support for zlib functions gzeof and gzsetparams.
158 * Added support for access to adler, total_in & total_out
160 * The compress function can now take an optional parameter that
161 allows the compression level to be specified. This mirrors the
162 compress2 function available in zlib.
164 * memGzip doesn't work properly with perl 5.8.0 when it is given
165 UTF-8 data. Bug spotted by Andreas J. Koenig.
167 * Added note about Linux zlib-devel RPM to README.
169 * Fixed recursive build problem on win32 machines.
171 * Fixed problem with the test harness on Mac OS X.
172 Thanks to Carl Johan Berglund for reporting the problem and
173 helping track it down.
176 1.16 - 13 December 2001
178 * Fixed bug in Makefile.PL that stopped "perl Makefile.PL PREFIX=..."
181 1.15 - 4th December 2001
183 * Changes a few types to get the module to build on 64-bit Solaris
185 * Changed the up/downgrade logic to default to the older constructs, and
186 to only call a downgrade if specifically requested. Some older versions
187 of Perl were having problems with the in-place edit.
189 * added the new XS constant code.
191 1.14 - 27th August 2001
193 * Memory overwrite bug fixed in "inflate". Kudos to Rob Simons for
194 reporting the bug and to Anton Berezin for fixing it for me.
196 1.13 - 31st June 2001
198 * Make sure config.in is consistent when released.
200 1.12 - 28th April 2001
202 * Modified Makefile.PL to only enable the warnings pragma if
203 using perl 5.6.1 or better.
205 1.11 - 17th February 2001
207 * Added logic in Makefile.PL to toggle between using $^W and
208 the warnings pragma in the module.
210 * The module, the examples & the test harness are now all strict
213 1.10 - 5th February 2001
215 * fixed a bug in memGunzip. Used Z_ERR instead of Z_DATA_ERROR.
217 1.09 - 15th January 2001
219 * Silenced a few compiler warnings.
221 * Updated zlib home site in README & Zlib.pm to www.info-zip.org
223 * Minor typo in Zlib.pm - a link used AUTHORS instead of AUTHOR
224 -- spotted by Frank Martini.
226 * Mention Archive::Zip
228 * added memGunzip. This is largely based on code provided by Jim Leonard.
230 * $deflate->flush can now take an optional parameter. Valid
231 values are Z_NO_FLUSH, Z_PARTIAL_FLUSH, Z_SYNC_FLUSH, Z_FULL_FLUSH
232 and Z_FINISH. The default is Z_FINISH.
236 * uncompress was clobbering its input parameter. Now it doesn't.
237 This bug was spotted by Deven T. Corzine.
239 * If a variable that only ever contained a number was given
240 to compress or deflate, it would not be compressed properly. Now
241 it will be coerced to a string and then compressed. This bug
242 was spotted by Deven T. Corzine.
246 * ANSI-ified the static functions in Zlib.xs
248 * Added the ability to build zlib along with the module.
249 This feature is 90% based on a Makefile provided by Gurusamy
254 * Fixed a nasty problem where inflate could truncate the data
255 returned. Thanks to Douglas Thomson <dougt@mugc.cc.monash.edu.au>
256 for both spotting the problem and fixing the bug.
258 * Added a note about the undocumented features in zlib that are
259 required when accessing zip files.
261 * gzclose will now get called automatically when the gzip object is
266 * Previous release used newSVpvn, which doesn't exist in 5.004_04
267 or earlier. Changed to use newSVpv instead.
269 * The module needs Perl 5.004 or better, so updated the version
270 checking in Zlib.pm and Makefile.PL
274 * Bug 19990527.001: compress(undef) core dumps -- Fixed.
278 * Updated to use the new PL_ symbols.
279 Means the module can be built with Perl 5.005_5*
283 * The return codes for gzread, gzreadline and gzwrite were
284 documented incorrectly as returning a status code.
286 * The test harness was missing a "gzclose". This caused problem
287 showed up on an amiga. Thanks to Erik van Roode for reporting
290 * Patched zlib.t for OS/2. Thanks to Ilya Zakharevich for the patch.
294 * A number of fixes to the test suite and the example scripts to
295 allow them to work under win32. All courtesy of Gurusamy
300 * Fixed crc32 & adler32. They were very broken.
302 * The following functions can now take a scalar reference in
303 place of a scalar for their buffer parameters:
312 This should mean applications that make use of the module don't
313 have to copy large buffers around.
316 * Normally the inflate method consumes I<all> of the input buffer
317 before returning. The exception to this is when inflate detects
318 the end of the stream (Z_STREAM_END). In this case the input
319 buffer need not be completely consumed. To allow processing of
320 file formats that embed a deflation stream (e.g. zip, gzip),
321 the inflate method now sets the buffer parameter to be what
322 remains after inflation.
324 When the return status is Z_STREAM_END, it will be what remains
325 of the buffer (if any) after deflation. When the status is Z_OK
326 it will be an empty string.
328 This change means that the buffer parameter must be a lvalue.
330 * Fixed crc32 and adler32. They were both very broken.
332 * Added the Compress::Zlib::memGzip function.
334 0.5 - Confirmed that no changes were necessary for zlib 1.0.3, or 1.0.4.
336 The optional parameters for deflateInit and inflateInit can now
337 be specified as an associative array in addition to a reference
338 to an associative array. They can also accept the -Name
341 gzopen can now optionally take a reference to an open
342 filehandle in place of a filename. In this case it will call
345 Added gzstream example script.
347 0.4 - Upgrade to support zlib 0.99
349 Added dictionary interface.
351 Fixed bug in gzreadline - previously it would keep returning
352 the same buffer. This bug was reported by Helmut Jarausch
354 Removed dependency to zutil.h and so dropped support for
356 DEF_MEM_LEVEL (use MAX_MEM_LEVEL instead)
357 DEF_WBITS (use MAX_WBITS instead)
359 0.3 - Added prototype specification.
361 0.2 - Fixed a minor allocation problem in Zlib.xs
363 0.1 - first alpha release. 2nd October 1995
