93
94
f4c6fd49 95 1.34 - 30 January 2005
96
97 * Fixed typo in the README
98
99 * Fixed examples.t on Win32 where paths have embedded whitespace.
100
101 * Fix for Cygwin and core integration from Jos I. Boumans
102
103 * Upgrade zlib source to 1.2.2
104
105 1.33 - 14 January 2004
106
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.
109
110 * Patches for Makefile.PL to get it to work on VMS supplied by
111 Craig A. Berry.
112
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
117 memory allocation.
118
119 1.32 - 26 November 2003
120
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
125
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.
128
129 * Fixed a bug in the inflate method where the input buffer is an
130 lvalue (via substr). Problem & solution reported by Salvador Fandiqo.
131
132 * Tightened up the logic in Makefile.PL when BUILD_ZLIB is
133 True. Issue spotted by Ralf S. Engelschall.
134
135 1.31 - 29 October 2003
136
137 * Reinstated the creation of .bak files - $^I seems to need a
642e522c 138 backup file on Windows. For OpenVMS, the extenstion _bak is used.
f4c6fd49 139
140 1.30 - 28 October 2003
141
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.
146
147 * Added prototypes to the subs in Zlib.pm that didn't already have
148 them. Patch from Ed Avis.
149
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
153 on OpenVMS.
154
155 * Documentation for some of the gz functions updated.
156
157 * Format strings modified in DispStream to keep OpenVMS happy.
158 Problem reported by Dr. Martin Zinser.
159
160
161 1.22 - 17 June 2003
162
163 * Makefile.PL now displays a warning about not installing
164 Compress::Zlib via the CPAN shell.
165
166 * Fix to allow intermingling of gzread & gzreadline - patch
167 supplied by Doug Perham.
168
169 * memGunzip will silently now work if the gzip trailer is
170 missing. Some HTTP Origin Servers seem to leave it out.
171
172 1.21 - 28 April 2003
173
174 * Tests 148 & 150 from t/02zlib.t were failing on redhat 9.
175
176 * Added a few words about the problems with Mac OS X to the README file.
177
178 1.20 - 4 April 2003
179
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
185 return value.
186
187 1.19 - 31 October 2002
188
189 * fixed a problem with t/02zlib.t that was failing with redhat 8.
190
191 1.18 - 24 October 2002
192
193 * fixed a Win32 problem in t/02zlib.t by changing sysread to read.
194
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
198
642e522c 199 1.17 - 23 May 2002
f4c6fd49 200
201 * Moved the test to check the versions of libz & zlib.h into a separate
202 file and added troubleshooting notes to README.
203
204 * In gzopen, only attempt to call "tell" for normal files.
205
642e522c 206 * Fixed to work in taint mode.
207
f4c6fd49 208 * Broke changes out of README into Changes file.
209
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 */
212
f4c6fd49 213 1.16 - 13 December 2001
214
215 * Fixed bug in Makefile.PL that stopped "perl Makefile.PL PREFIX=..."
216 working.
217
218 1.15 - 4th December 2001
219
220 * Changes a few types to get the module to build on 64-bit Solaris
221
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.
225
226 * added the new XS constant code.
227
228 1.14 - 27th August 2001
229
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.
232
233 1.13 - 31st June 2001
234
642e522c 235 * Make sure config.in is consistant when released.
f4c6fd49 236
237 1.12 - 28th April 2001
238
239 * Modified Makefile.PL to only enable the warnings pragma if
240 using perl 5.6.1 or better.
241
242 1.11 - 17th February 2001
243
244 * Added logic in Makefile.PL to toggle between using $^W and
245 the warnings pragma in the module.
246
247 * The module, the examples & the test harness are now all strict
248 & warnings clean.
249
250 1.10 - 5th February 2001
251
252 * fixed a bug in memGunzip. Used Z_ERR instead of Z_DATA_ERROR.
253
254 1.09 - 15th January 2001
255
256 * Silenced a few compiler warnings.
257
258 * Updated zlib home site in README & Zlib.pm to www.info-zip.org
259
260 * Minor typo in Zlib.pm - a link used AUTHORS instead of AUTHOR
261 -- spotted by Frank Martini.
262
263 * Mention Archive::Zip
264
265 * added memGunzip. This is largely based on code provided by Jim Leonard.
266
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.
270
271 1.08 - 6 Jan 2000
272
273 * uncompress was clobbering its input parameter. Now it doesn't.
274 This bug was spotted by Deven T. Corzine.
275
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.
280
281 1.07 - 27 Nov 1999
282
283 * ANSI-ified the static functions in Zlib.xs
284
285 * Added the ability to build zlib along with the module.
286 This feature is 90% based on a Makefile provided by Gurusamy
287 Sarathy.
288
289 1.06 - 20 Sep 1999
290
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.
294
295 * Added a note about the undocumented features in zlib that are
296 required when accessing zip files.
297
298 * gzclose will now get called automatically when the gzip object is
299 destroyed.
300
301 1.05 - 3 June 1999
302
303 * Previous release used newSVpvn, which doesn't exist in 5.004_04
304 or earlier. Changed to use newSVpv instead.
305
306 * The module needs Perl 5.004 or better, so updated the version
307 checking in Zlib.pm and Makefile.PL
308
309 1.04 - 27 May 1999
310
311 * Bug 19990527.001: compress(undef) core dumps -- Fixed.
312
313 1.03 - 17 Mar 1999
314
315 * Updated to use the new PL_ symbols.
316 Means the module can be built with Perl 5.005_5*
317
318 1.02 - 31 Jan 1999
319
320 * The return codes for gzread, gzreadline and gzwrite were
321 documented incorrectly as returning a status code.
322
323 * The test harness was missing a "gzclose". This caused problem
324 showed up on an amiga. Thanks to Erik van Roode for reporting
325 this one.
326
327 * Patched zlib.t for OS/2. Thanks to Ilya Zakharevich for the patch.
328
329 1.01 - 23 Nov 1997
330
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
333 Sarathy.
334
335 1.00 - 14 Nov 1997
336
337 * Fixed crc32 & adler32. They were very broken.
338
339 * The following functions can now take a scalar reference in
340 place of a scalar for their buffer parameters:
341
342 compress
343 uncompress
344 deflate
345 inflate
346 crc32
347 adler32
348
349 This should mean applications that make use of the module don't
350 have to copy large buffers around.
351
352
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.
360
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.
364
365 This change means that the buffer parameter must be a lvalue.
366
367 * Fixed crc32 and adler32. They were both very broken.
368
369 * Added the Compress::Zlib::memGzip function.
370
371 0.5 - Confirmed that no changes were necessary for zlib 1.0.3, or 1.0.4.
372
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
376 syntax.
377
378 gzopen can now optionally take a reference to an open
379 filehandle in place of a filename. In this case it will call
380 gzdopen.
381
382 Added gzstream example script.
383
384 0.4 - Upgrade to support zlib 0.99
385
386 Added dictionary interface.
387
388 Fixed bug in gzreadline - previously it would keep returning
389 the same buffer. This bug was reported by Helmut Jarausch
390
391 Removed dependency to zutil.h and so dropped support for
392
393 DEF_MEM_LEVEL (use MAX_MEM_LEVEL instead)
394 DEF_WBITS (use MAX_WBITS instead)
395
396 0.3 - Added prototype specification.
397
398 0.2 - Fixed a minor allocation problem in Zlib.xs
399
400 0.1 - first alpha release. 2nd October 1995
