38 | 2.000_12 16 April 2006 |
39 | |
40 | * Fixed gzread to zap the output buffer to an empty string when zero |
41 | bytes are requested. This matches the behaviour of C::Z 1.x |
42 | |
43 | 2.000_11 10 April 2006 |
44 | |
45 | * No changes. |
46 | |

47 | 2.000_10 13 March 2006 |
48 | |
49 | * Changed gzread so that its behaviour matches C::Z::gzread 1.x if it |
50 | is called after eof. In this case it will write an empty string |
51 | into the output parameter. This change is solely for backward |
52 | compatability reasons. |

114 | |
5993747c |
115 | 1.37 - 12 August 2005 |
116 | |
117 | * Change to t/03examples.t for VMS from Abe Timmerman |
118 | |

06edba15 |
129 | 1.35 - 16 July 2005 |
130 | |
131 | * Updated zlib source to 1.2.3 |
132 | |
133 | * Fixed problem with where two calls to gzclose would hang the debugger. |
134 | See https://rt.cpan.org/Ticket/Display.html?id=13789 |
135 | |
136 | * Added code from Alexey Tourbin to use XSLoader when available, |

138 | |
139 | * Documented that the compress & uncompress functions were not |
140 | the same as the Unix utilities of the same name. |

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