51
c70c1701 52 2.000_12 16 April 2006
53
54 * Fixed gzread to zap the output buffer to an empty string when zero
55 bytes are requested. This matches the behaviour of C::Z 1.x
56
57 2.000_11 10 April 2006
58
59 * No changes.
60
cb7abd7f 61 2.000_10 13 March 2006
62
63 * Changed gzread so that its behaviour matches C::Z::gzread 1.x if it
64 is called after eof. In this case it will write an empty string
65 into the output parameter. This change is solely for backward
66 compatability reasons.

5e282033 122
76e6f389 123 1.38 - 6 September 2005
124
125 * Integrate core change 25304 -- Symbian Update
126
127 * Added libscan to Makefile.PL
128
5993747c 129 1.37 - 12 August 2005
130
131 * Change to t/03examples.t for VMS from Abe Timmerman
132
133 1.36 - 3 August 2005
134
135 * Renamed zlib-src-1.2.3 to zlib-src to help VMS
136
137 * Fixed Makefile.PL for VMS
138
139 * Fixed t/03examples.t for VMS
140
141 * Added a couple of notes about incompatibility with Unix compress.
142
06edba15 143 1.35 - 16 July 2005
144
145 * Updated zlib source to 1.2.3
146
147 * Fixed problem with where two calls to gzclose would hang the debugger.
148 See https://rt.cpan.org/Ticket/Display.html?id=13789
149
150 * Added code from Alexey Tourbin to use XSLoader when available,
151 and DynaLoader otherwise.
152
153 * Documented that the compress & uncompress functions were not
154 the same as the Unix utilities of the same name.
155
156 * Fixed 05gzsetp -- it left a temp file hanging around.
157
158 * Integrate core change 24787 - SvUPGRADE returns void in blead
159
160 * Integrate core change 24788 - Makefile.PL adjustments for the core
161
162
f4c6fd49 163 1.34 - 30 January 2005
164
165 * Fixed typo in the README
166
167 * Fixed examples.t on Win32 where paths have embedded whitespace.
168
169 * Fix for Cygwin and core integration from Jos I. Boumans
170
171 * Upgrade zlib source to 1.2.2
172
173 1.33 - 14 January 2004
174
175 * Reworked Makefile.PL to avoid creating a private copy of zlib.
176 This both simplifies the build, plus it makes life easier for VMS.
177
178 * Patches for Makefile.PL to get it to work on VMS supplied by
179 Craig A. Berry.
180
181 * memGunzip has very slow on FreeBSD. Turns out to be down to
182 the way realloc works on FreeBSD. Changed both inflate & deflate
183 to use exponentially increasing buffer sizes when they need to
184 realloc. Thanks to Peter Jeremy for the lowdown on FreeBSD
185 memory allocation.
186
187 1.32 - 26 November 2003
188
189 * Steve Hay reported a problem on rt.cpan.org with Windows and
190 MSCV++ 6.0 where the source from the zlib directory was getting
191 installed with the rest of the module.
192 https://rt.cpan.org/Ticket/Display.html?id=1741
193
194 This has been fixed by renaming the "zlib" directory to "zlib-src"
195 thus avoiding a conflict with the name of this Perl module.
196
197 * Fixed a bug in the inflate method where the input buffer is an
198 lvalue (via substr). Problem & solution reported by Salvador Fandiqo.
199
200 * Tightened up the logic in Makefile.PL when BUILD_ZLIB is
201 True. Issue spotted by Ralf S. Engelschall.
202
203 1.31 - 29 October 2003
204
205 * Reinstated the creation of .bak files - $^I seems to need a
642e522c 206 backup file on Windows. For OpenVMS, the extenstion _bak is used.
f4c6fd49 207
208 1.30 - 28 October 2003
209
210 * Bundled a sub-set of the zlib source with the module and changed
211 the default make behaviour to build with the included zlib source.
212 The previous behaviour of using a pre-built zlib library is
213 still available for those that want it.
214
215 * Added prototypes to the subs in Zlib.pm that didn't already have
216 them. Patch from Ed Avis.
217
218 * No .bak files are created by Makefile.PL any more - this keep
219 distclean much happier. Patch suggested by Ed Avis.
220 This also fixes a similar problem reported by Dr. Martin Zinser
221 on OpenVMS.
222
223 * Documentation for some of the gz functions updated.
224
225 * Format strings modified in DispStream to keep OpenVMS happy.
226 Problem reported by Dr. Martin Zinser.
227
228
229 1.22 - 17 June 2003
230
231 * Makefile.PL now displays a warning about not installing
232 Compress::Zlib via the CPAN shell.
233
234 * Fix to allow intermingling of gzread & gzreadline - patch
235 supplied by Doug Perham.
236
237 * memGunzip will silently now work if the gzip trailer is
238 missing. Some HTTP Origin Servers seem to leave it out.
239
240 1.21 - 28 April 2003
241
242 * Tests 148 & 150 from t/02zlib.t were failing on redhat 9.
243
244 * Added a few words about the problems with Mac OS X to the README file.
245
246 1.20 - 4 April 2003
247
248 * Fixed bug in gzopen where $gzerrno wasn't being set correctly.
249 The symptom was $gzerrno was set to Z_MEM_ERROR although the file
250 was opened ok. If gzopen failed, $gzerrno was being set correctly.
251 This problem wasn't spotted before because the typical test
252 to determine whether gzopen passed or failed was to check its
253 return value.
254
255 1.19 - 31 October 2002
256
257 * fixed a problem with t/02zlib.t that was failing with redhat 8.
258
259 1.18 - 24 October 2002
260
261 * fixed a Win32 problem in t/02zlib.t by changing sysread to read.
262
263 * zlib 1.0.5 & older doesn't have gzsetparams & gzeof. Added a new
264 variable to config.in to flag an old version of zlib. Split
265 out the tests for gzsetparams into t/05gzsetp.t
266
642e522c 267 1.17 - 23 May 2002
f4c6fd49 268
269 * Moved the test to check the versions of libz & zlib.h into a separate
270 file and added troubleshooting notes to README.
271
272 * In gzopen, only attempt to call "tell" for normal files.
273
642e522c 274 * Fixed to work in taint mode.
275
f4c6fd49 276 * Broke changes out of README into Changes file.
277
278 * Replaced internal use of Z_PARTIAL_FLUSH symbol with Z_SYNC_FLUSH.
279 zlib.h says /* will be removed, use Z_SYNC_FLUSH instead */
280
f4c6fd49 281 1.16 - 13 December 2001
282
283 * Fixed bug in Makefile.PL that stopped "perl Makefile.PL PREFIX=..."
284 working.
285
286 1.15 - 4th December 2001
287
288 * Changes a few types to get the module to build on 64-bit Solaris
289
290 * Changed the up/downgrade logic to default to the older constructs, and
291 to only call a downgrade if specifically requested. Some older versions
292 of Perl were having problems with the in-place edit.
293
294 * added the new XS constant code.
295
296 1.14 - 27th August 2001
297
298 * Memory overwrite bug fixed in "inflate". Kudos to Rob Simons for
299 reporting the bug and to Anton Berezin for fixing it for me.
300
301 1.13 - 31st June 2001
302
642e522c 303 * Make sure config.in is consistant when released.
f4c6fd49 304
305 1.12 - 28th April 2001
306
307 * Modified Makefile.PL to only enable the warnings pragma if
308 using perl 5.6.1 or better.
309
310 1.11 - 17th February 2001
311
312 * Added logic in Makefile.PL to toggle between using $^W and
313 the warnings pragma in the module.
314
315 * The module, the examples & the test harness are now all strict
316 & warnings clean.
317
318 1.10 - 5th February 2001
319
320 * fixed a bug in memGunzip. Used Z_ERR instead of Z_DATA_ERROR.
321
322 1.09 - 15th January 2001
323
324 * Silenced a few compiler warnings.
325
326 * Updated zlib home site in README & Zlib.pm to www.info-zip.org
327
328 * Minor typo in Zlib.pm - a link used AUTHORS instead of AUTHOR
329 -- spotted by Frank Martini.
330
331 * Mention Archive::Zip
332
333 * added memGunzip. This is largely based on code provided by Jim Leonard.
334
335 * $deflate->flush can now take an optional parameter. Valid
336 values are Z_NO_FLUSH, Z_PARTIAL_FLUSH, Z_SYNC_FLUSH, Z_FULL_FLUSH
337 and Z_FINISH. The default is Z_FINISH.
338
339 1.08 - 6 Jan 2000
340
341 * uncompress was clobbering its input parameter. Now it doesn't.
342 This bug was spotted by Deven T. Corzine.
343
344 * If a variable that only ever contained a number was given
345 to compress or deflate, it would not be compressed properly. Now
346 it will be coerced to a string and then compressed. This bug
347 was spotted by Deven T. Corzine.
348
349 1.07 - 27 Nov 1999
350
351 * ANSI-ified the static functions in Zlib.xs
352
353 * Added the ability to build zlib along with the module.
354 This feature is 90% based on a Makefile provided by Gurusamy
355 Sarathy.
356
357 1.06 - 20 Sep 1999
358
359 * Fixed a nasty problem where inflate could truncate the data
360 returned. Thanks to Douglas Thomson <dougt@mugc.cc.monash.edu.au>
361 for both spotting the problem and fixing the bug.
362
363 * Added a note about the undocumented features in zlib that are
364 required when accessing zip files.
365
366 * gzclose will now get called automatically when the gzip object is
367 destroyed.
368
369 1.05 - 3 June 1999
370
371 * Previous release used newSVpvn, which doesn't exist in 5.004_04
372 or earlier. Changed to use newSVpv instead.
373
374 * The module needs Perl 5.004 or better, so updated the version
375 checking in Zlib.pm and Makefile.PL
376
377 1.04 - 27 May 1999
378
379 * Bug 19990527.001: compress(undef) core dumps -- Fixed.
380
381 1.03 - 17 Mar 1999
382
383 * Updated to use the new PL_ symbols.
384 Means the module can be built with Perl 5.005_5*
385
386 1.02 - 31 Jan 1999
387
388 * The return codes for gzread, gzreadline and gzwrite were
389 documented incorrectly as returning a status code.
390
391 * The test harness was missing a "gzclose". This caused problem
392 showed up on an amiga. Thanks to Erik van Roode for reporting
393 this one.
394
395 * Patched zlib.t for OS/2. Thanks to Ilya Zakharevich for the patch.
396
397 1.01 - 23 Nov 1997
398
399 * A number of fixes to the test suite and the example scripts to
400 allow them to work under win32. All courtesy of Gurusamy
401 Sarathy.
402
403 1.00 - 14 Nov 1997
404
405 * Fixed crc32 & adler32. They were very broken.
406
407 * The following functions can now take a scalar reference in
408 place of a scalar for their buffer parameters:
409
410 compress
411 uncompress
412 deflate
413 inflate
414 crc32
415 adler32
416
417 This should mean applications that make use of the module don't
418 have to copy large buffers around.
419
420
421 * Normally the inflate method consumes I<all> of the input buffer
422 before returning. The exception to this is when inflate detects
423 the end of the stream (Z_STREAM_END). In this case the input
424 buffer need not be completely consumed. To allow processing of
425 file formats that embed a deflation stream (e.g. zip, gzip),
426 the inflate method now sets the buffer parameter to be what
427 remains after inflation.
428
429 When the return status is Z_STREAM_END, it will be what remains
430 of the buffer (if any) after deflation. When the status is Z_OK
431 it will be an empty string.
432
433 This change means that the buffer parameter must be a lvalue.
434
435 * Fixed crc32 and adler32. They were both very broken.
436
437 * Added the Compress::Zlib::memGzip function.
438
439 0.5 - Confirmed that no changes were necessary for zlib 1.0.3, or 1.0.4.
440
441 The optional parameters for deflateInit and inflateInit can now
442 be specified as an associative array in addition to a reference
443 to an associative array. They can also accept the -Name
444 syntax.
445
446 gzopen can now optionally take a reference to an open
447 filehandle in place of a filename. In this case it will call
448 gzdopen.
449
450 Added gzstream example script.
451
452 0.4 - Upgrade to support zlib 0.99
453
454 Added dictionary interface.
455
456 Fixed bug in gzreadline - previously it would keep returning
457 the same buffer. This bug was reported by Helmut Jarausch
458
459 Removed dependency to zutil.h and so dropped support for
460
461 DEF_MEM_LEVEL (use MAX_MEM_LEVEL instead)
462 DEF_WBITS (use MAX_WBITS instead)
463
464 0.3 - Added prototype specification.
465
466 0.2 - Fixed a minor allocation problem in Zlib.xs
467
468 0.1 - first alpha release. 2nd October 1995
