14 | |
15 | * lib/Compress/Zlib.pm -- 1.x Backward Compatability issues |
16 | gzclose - documented return value was wrong, should be 0 for ok. |
17 | gzflush - return value didn't match 1.x, should return 0 if ok. |
18 | [rt.cpan.org #29215] and Debian bug #440943 http://bugs.debian.org/440943 |

68 | 2.000_12 16 April 2006 |
69 | |
70 | * Fixed gzread to zap the output buffer to an empty string when zero |
71 | bytes are requested. This matches the behaviour of C::Z 1.x |
72 | |
73 | 2.000_11 10 April 2006 |
74 | |
75 | * No changes. |
76 | |
cb7abd7f |
77 | 2.000_10 13 March 2006 |
78 | |
79 | * Changed gzread so that its behaviour matches C::Z::gzread 1.x if it |
80 | is called after eof. In this case it will write an empty string |
81 | into the output parameter. This change is solely for backward |
82 | compatability reasons. |

139 | 1.38 - 6 September 2005 |
140 | |
141 | * Integrate core change 25304 -- Symbian Update |
142 | |
143 | * Added libscan to Makefile.PL |
144 | |
5993747c |
145 | 1.37 - 12 August 2005 |
146 | |
147 | * Change to t/03examples.t for VMS from Abe Timmerman |
148 | |
149 | 1.36 - 3 August 2005 |
150 | |
151 | * Renamed zlib-src-1.2.3 to zlib-src to help VMS |
152 | |
153 | * Fixed Makefile.PL for VMS |
154 | |
155 | * Fixed t/03examples.t for VMS |
156 | |

158 | |
06edba15 |
159 | 1.35 - 16 July 2005 |
160 | |
161 | * Updated zlib source to 1.2.3 |
162 | |
163 | * Fixed problem with where two calls to gzclose would hang the debugger. |
164 | See https://rt.cpan.org/Ticket/Display.html?id=13789 |
165 | |
166 | * Added code from Alexey Tourbin to use XSLoader when available, |
167 | and DynaLoader otherwise. |
168 | |
169 | * Documented that the compress & uncompress functions were not |
170 | the same as the Unix utilities of the same name. |
171 | |
172 | * Fixed 05gzsetp -- it left a temp file hanging around. |
173 | |
174 | * Integrate core change 24787 - SvUPGRADE returns void in blead |
175 | |
176 | * Integrate core change 24788 - Makefile.PL adjustments for the core |
177 | |
178 | |
f4c6fd49 |
179 | 1.34 - 30 January 2005 |
180 | |
181 | * Fixed typo in the README |
182 | |
183 | * Fixed examples.t on Win32 where paths have embedded whitespace. |
184 | |
185 | * Fix for Cygwin and core integration from Jos I. Boumans |
186 | |
187 | * Upgrade zlib source to 1.2.2 |
188 | |
189 | 1.33 - 14 January 2004 |
190 | |
191 | * Reworked Makefile.PL to avoid creating a private copy of zlib. |
192 | This both simplifies the build, plus it makes life easier for VMS. |
193 | |
194 | * Patches for Makefile.PL to get it to work on VMS supplied by |
195 | Craig A. Berry. |
196 | |
197 | * memGunzip has very slow on FreeBSD. Turns out to be down to |
198 | the way realloc works on FreeBSD. Changed both inflate & deflate |
199 | to use exponentially increasing buffer sizes when they need to |
200 | realloc. Thanks to Peter Jeremy for the lowdown on FreeBSD |
201 | memory allocation. |
202 | |
203 | 1.32 - 26 November 2003 |
204 | |
205 | * Steve Hay reported a problem on rt.cpan.org with Windows and |
206 | MSCV++ 6.0 where the source from the zlib directory was getting |
207 | installed with the rest of the module. |
208 | https://rt.cpan.org/Ticket/Display.html?id=1741 |
209 | |
210 | This has been fixed by renaming the "zlib" directory to "zlib-src" |
211 | thus avoiding a conflict with the name of this Perl module. |
212 | |
213 | * Fixed a bug in the inflate method where the input buffer is an |
214 | lvalue (via substr). Problem & solution reported by Salvador Fandiqo. |
215 | |
216 | * Tightened up the logic in Makefile.PL when BUILD_ZLIB is |
217 | True. Issue spotted by Ralf S. Engelschall. |
218 | |
219 | 1.31 - 29 October 2003 |
220 | |
221 | * Reinstated the creation of .bak files - $^I seems to need a |
642e522c |
222 | backup file on Windows. For OpenVMS, the extenstion _bak is used. |
f4c6fd49 |
223 | |
224 | 1.30 - 28 October 2003 |
225 | |
226 | * Bundled a sub-set of the zlib source with the module and changed |
227 | the default make behaviour to build with the included zlib source. |
228 | The previous behaviour of using a pre-built zlib library is |
229 | still available for those that want it. |
230 | |
231 | * Added prototypes to the subs in Zlib.pm that didn't already have |
232 | them. Patch from Ed Avis. |
233 | |
234 | * No .bak files are created by Makefile.PL any more - this keep |
235 | distclean much happier. Patch suggested by Ed Avis. |
236 | This also fixes a similar problem reported by Dr. Martin Zinser |
237 | on OpenVMS. |
238 | |
239 | * Documentation for some of the gz functions updated. |
240 | |
241 | * Format strings modified in DispStream to keep OpenVMS happy. |
242 | Problem reported by Dr. Martin Zinser. |
243 | |
244 | |
245 | 1.22 - 17 June 2003 |
246 | |
247 | * Makefile.PL now displays a warning about not installing |
248 | Compress::Zlib via the CPAN shell. |
249 | |
250 | * Fix to allow intermingling of gzread & gzreadline - patch |
251 | supplied by Doug Perham. |
252 | |
253 | * memGunzip will silently now work if the gzip trailer is |
254 | missing. Some HTTP Origin Servers seem to leave it out. |
255 | |
256 | 1.21 - 28 April 2003 |
257 | |
258 | * Tests 148 & 150 from t/02zlib.t were failing on redhat 9. |
259 | |
260 | * Added a few words about the problems with Mac OS X to the README file. |
261 | |
262 | 1.20 - 4 April 2003 |
263 | |
264 | * Fixed bug in gzopen where $gzerrno wasn't being set correctly. |
265 | The symptom was $gzerrno was set to Z_MEM_ERROR although the file |
266 | was opened ok. If gzopen failed, $gzerrno was being set correctly. |
267 | This problem wasn't spotted before because the typical test |
268 | to determine whether gzopen passed or failed was to check its |
269 | return value. |
270 | |
271 | 1.19 - 31 October 2002 |
272 | |
273 | * fixed a problem with t/02zlib.t that was failing with redhat 8. |
274 | |
275 | 1.18 - 24 October 2002 |
276 | |
277 | * fixed a Win32 problem in t/02zlib.t by changing sysread to read. |
278 | |
279 | * zlib 1.0.5 & older doesn't have gzsetparams & gzeof. Added a new |
280 | variable to config.in to flag an old version of zlib. Split |
281 | out the tests for gzsetparams into t/05gzsetp.t |
282 | |
642e522c |
283 | 1.17 - 23 May 2002 |
f4c6fd49 |
284 | |
285 | * Moved the test to check the versions of libz & zlib.h into a separate |
286 | file and added troubleshooting notes to README. |
287 | |
288 | * In gzopen, only attempt to call "tell" for normal files. |
289 | |
642e522c |
290 | * Fixed to work in taint mode. |
291 | |
f4c6fd49 |
292 | * Broke changes out of README into Changes file. |
293 | |
294 | * Replaced internal use of Z_PARTIAL_FLUSH symbol with Z_SYNC_FLUSH. |
295 | zlib.h says /* will be removed, use Z_SYNC_FLUSH instead */ |
296 | |
f4c6fd49 |
297 | 1.16 - 13 December 2001 |
298 | |
299 | * Fixed bug in Makefile.PL that stopped "perl Makefile.PL PREFIX=..." |
300 | working. |
301 | |
302 | 1.15 - 4th December 2001 |
303 | |
304 | * Changes a few types to get the module to build on 64-bit Solaris |
305 | |
306 | * Changed the up/downgrade logic to default to the older constructs, and |
307 | to only call a downgrade if specifically requested. Some older versions |
308 | of Perl were having problems with the in-place edit. |
309 | |
310 | * added the new XS constant code. |
311 | |
312 | 1.14 - 27th August 2001 |
313 | |
314 | * Memory overwrite bug fixed in "inflate". Kudos to Rob Simons for |
315 | reporting the bug and to Anton Berezin for fixing it for me. |
316 | |
317 | 1.13 - 31st June 2001 |
318 | |
642e522c |
319 | * Make sure config.in is consistant when released. |
f4c6fd49 |
320 | |
321 | 1.12 - 28th April 2001 |
322 | |
323 | * Modified Makefile.PL to only enable the warnings pragma if |
324 | using perl 5.6.1 or better. |
325 | |
326 | 1.11 - 17th February 2001 |
327 | |
328 | * Added logic in Makefile.PL to toggle between using $^W and |
329 | the warnings pragma in the module. |
330 | |
331 | * The module, the examples & the test harness are now all strict |
332 | & warnings clean. |
333 | |
334 | 1.10 - 5th February 2001 |
335 | |
336 | * fixed a bug in memGunzip. Used Z_ERR instead of Z_DATA_ERROR. |
337 | |
338 | 1.09 - 15th January 2001 |
339 | |
340 | * Silenced a few compiler warnings. |
341 | |
342 | * Updated zlib home site in README & Zlib.pm to www.info-zip.org |
343 | |
344 | * Minor typo in Zlib.pm - a link used AUTHORS instead of AUTHOR |
345 | -- spotted by Frank Martini. |
346 | |
347 | * Mention Archive::Zip |
348 | |
349 | * added memGunzip. This is largely based on code provided by Jim Leonard. |
350 | |
351 | * $deflate->flush can now take an optional parameter. Valid |
352 | values are Z_NO_FLUSH, Z_PARTIAL_FLUSH, Z_SYNC_FLUSH, Z_FULL_FLUSH |
353 | and Z_FINISH. The default is Z_FINISH. |
354 | |
355 | 1.08 - 6 Jan 2000 |
356 | |
357 | * uncompress was clobbering its input parameter. Now it doesn't. |
358 | This bug was spotted by Deven T. Corzine. |
359 | |
360 | * If a variable that only ever contained a number was given |
361 | to compress or deflate, it would not be compressed properly. Now |
362 | it will be coerced to a string and then compressed. This bug |
363 | was spotted by Deven T. Corzine. |
364 | |
365 | 1.07 - 27 Nov 1999 |
366 | |
367 | * ANSI-ified the static functions in Zlib.xs |
368 | |
369 | * Added the ability to build zlib along with the module. |
370 | This feature is 90% based on a Makefile provided by Gurusamy |
371 | Sarathy. |
372 | |
373 | 1.06 - 20 Sep 1999 |
374 | |
375 | * Fixed a nasty problem where inflate could truncate the data |
376 | returned. Thanks to Douglas Thomson <dougt@mugc.cc.monash.edu.au> |
377 | for both spotting the problem and fixing the bug. |
378 | |
379 | * Added a note about the undocumented features in zlib that are |
380 | required when accessing zip files. |
381 | |
382 | * gzclose will now get called automatically when the gzip object is |
383 | destroyed. |
384 | |
385 | 1.05 - 3 June 1999 |
386 | |
387 | * Previous release used newSVpvn, which doesn't exist in 5.004_04 |
388 | or earlier. Changed to use newSVpv instead. |
389 | |
390 | * The module needs Perl 5.004 or better, so updated the version |
391 | checking in Zlib.pm and Makefile.PL |
392 | |
393 | 1.04 - 27 May 1999 |
394 | |
395 | * Bug 19990527.001: compress(undef) core dumps -- Fixed. |
396 | |
397 | 1.03 - 17 Mar 1999 |
398 | |
399 | * Updated to use the new PL_ symbols. |
400 | Means the module can be built with Perl 5.005_5* |
401 | |
402 | 1.02 - 31 Jan 1999 |
403 | |
404 | * The return codes for gzread, gzreadline and gzwrite were |
405 | documented incorrectly as returning a status code. |
406 | |
407 | * The test harness was missing a "gzclose". This caused problem |
408 | showed up on an amiga. Thanks to Erik van Roode for reporting |
409 | this one. |
410 | |
411 | * Patched zlib.t for OS/2. Thanks to Ilya Zakharevich for the patch. |
412 | |
413 | 1.01 - 23 Nov 1997 |
414 | |
415 | * A number of fixes to the test suite and the example scripts to |
416 | allow them to work under win32. All courtesy of Gurusamy |
417 | Sarathy. |
418 | |
419 | 1.00 - 14 Nov 1997 |
420 | |
421 | * Fixed crc32 & adler32. They were very broken. |
422 | |
423 | * The following functions can now take a scalar reference in |
424 | place of a scalar for their buffer parameters: |
425 | |
426 | compress |
427 | uncompress |
428 | deflate |
429 | inflate |
430 | crc32 |
431 | adler32 |
432 | |
433 | This should mean applications that make use of the module don't |
434 | have to copy large buffers around. |
435 | |
436 | |
437 | * Normally the inflate method consumes I<all> of the input buffer |
438 | before returning. The exception to this is when inflate detects |
439 | the end of the stream (Z_STREAM_END). In this case the input |
440 | buffer need not be completely consumed. To allow processing of |
441 | file formats that embed a deflation stream (e.g. zip, gzip), |
442 | the inflate method now sets the buffer parameter to be what |
443 | remains after inflation. |
444 | |
445 | When the return status is Z_STREAM_END, it will be what remains |
446 | of the buffer (if any) after deflation. When the status is Z_OK |
447 | it will be an empty string. |
448 | |
449 | This change means that the buffer parameter must be a lvalue. |
450 | |
451 | * Fixed crc32 and adler32. They were both very broken. |
452 | |
453 | * Added the Compress::Zlib::memGzip function. |
454 | |
455 | 0.5 - Confirmed that no changes were necessary for zlib 1.0.3, or 1.0.4. |
456 | |
457 | The optional parameters for deflateInit and inflateInit can now |
458 | be specified as an associative array in addition to a reference |
459 | to an associative array. They can also accept the -Name |
460 | syntax. |
461 | |
462 | gzopen can now optionally take a reference to an open |
463 | filehandle in place of a filename. In this case it will call |
464 | gzdopen. |
465 | |
466 | Added gzstream example script. |
467 | |
468 | 0.4 - Upgrade to support zlib 0.99 |
469 | |
470 | Added dictionary interface. |
471 | |
472 | Fixed bug in gzreadline - previously it would keep returning |
473 | the same buffer. This bug was reported by Helmut Jarausch |
474 | |
475 | Removed dependency to zutil.h and so dropped support for |
476 | |
477 | DEF_MEM_LEVEL (use MAX_MEM_LEVEL instead) |
478 | DEF_WBITS (use MAX_WBITS instead) |
479 | |
480 | 0.3 - Added prototype specification. |
481 | |
482 | 0.2 - Fixed a minor allocation problem in Zlib.xs |
483 | |
484 | 0.1 - first alpha release. 2nd October 1995 |
