1 | CHANGES |
2 | ------- | |
3 | ||
4 | 1.34 - 30 January 2005 | |
5 | ||
6 | * Fixed typo in the README | |
7 | ||
8 | * Fixed examples.t on Win32 where paths have embedded whitespace. | |
9 | ||
10 | * Fix for Cygwin and core integration from Jos I. Boumans | |
11 | ||
12 | * Upgrade zlib source to 1.2.2 | |
13 | ||
14 | 1.33 - 14 January 2004 | |
15 | ||
16 | * Reworked Makefile.PL to avoid creating a private copy of zlib. | |
17 | This both simplifies the build, plus it makes life easier for VMS. | |
18 | ||
19 | * Patches for Makefile.PL to get it to work on VMS supplied by | |
20 | Craig A. Berry. | |
21 | ||
22 | * memGunzip has very slow on FreeBSD. Turns out to be down to | |
23 | the way realloc works on FreeBSD. Changed both inflate & deflate | |
24 | to use exponentially increasing buffer sizes when they need to | |
25 | realloc. Thanks to Peter Jeremy for the lowdown on FreeBSD | |
26 | memory allocation. | |
27 | ||
28 | 1.32 - 26 November 2003 | |
29 | ||
30 | * Steve Hay reported a problem on rt.cpan.org with Windows and | |
31 | MSCV++ 6.0 where the source from the zlib directory was getting | |
32 | installed with the rest of the module. | |
33 | https://rt.cpan.org/Ticket/Display.html?id=1741 | |
34 | ||
35 | This has been fixed by renaming the "zlib" directory to "zlib-src" | |
36 | thus avoiding a conflict with the name of this Perl module. | |
37 | ||
38 | * Fixed a bug in the inflate method where the input buffer is an | |
39 | lvalue (via substr). Problem & solution reported by Salvador Fandiqo. | |
40 | ||
41 | * Tightened up the logic in Makefile.PL when BUILD_ZLIB is | |
42 | True. Issue spotted by Ralf S. Engelschall. | |
43 | ||
44 | 1.31 - 29 October 2003 | |
45 | ||
46 | * Reinstated the creation of .bak files - $^I seems to need a | |
47 | backup file on Windows. For OpenVMS, the extenstion _bak is used. | |
48 | ||
49 | 1.30 - 28 October 2003 | |
50 | ||
51 | * Bundled a sub-set of the zlib source with the module and changed | |
52 | the default make behaviour to build with the included zlib source. | |
53 | The previous behaviour of using a pre-built zlib library is | |
54 | still available for those that want it. | |
55 | ||
56 | * Added prototypes to the subs in Zlib.pm that didn't already have | |
57 | them. Patch from Ed Avis. | |
58 | ||
59 | * No .bak files are created by Makefile.PL any more - this keep | |
60 | distclean much happier. Patch suggested by Ed Avis. | |
61 | This also fixes a similar problem reported by Dr. Martin Zinser | |
62 | on OpenVMS. | |
63 | ||
64 | * Documentation for some of the gz functions updated. | |
65 | ||
66 | * Format strings modified in DispStream to keep OpenVMS happy. | |
67 | Problem reported by Dr. Martin Zinser. | |
68 | ||
69 | ||
70 | 1.22 - 17 June 2003 | |
71 | ||
72 | * Makefile.PL now displays a warning about not installing | |
73 | Compress::Zlib via the CPAN shell. | |
74 | ||
75 | * Fix to allow intermingling of gzread & gzreadline - patch | |
76 | supplied by Doug Perham. | |
77 | ||
78 | * memGunzip will silently now work if the gzip trailer is | |
79 | missing. Some HTTP Origin Servers seem to leave it out. | |
80 | ||
81 | 1.21 - 28 April 2003 | |
82 | ||
83 | * Tests 148 & 150 from t/02zlib.t were failing on redhat 9. | |
84 | ||
85 | * Added a few words about the problems with Mac OS X to the README file. | |
86 | ||
87 | 1.20 - 4 April 2003 | |
88 | ||
89 | * Fixed bug in gzopen where $gzerrno wasn't being set correctly. | |
90 | The symptom was $gzerrno was set to Z_MEM_ERROR although the file | |
91 | was opened ok. If gzopen failed, $gzerrno was being set correctly. | |
92 | This problem wasn't spotted before because the typical test | |
93 | to determine whether gzopen passed or failed was to check its | |
94 | return value. | |
95 | ||
96 | 1.19 - 31 October 2002 | |
97 | ||
98 | * fixed a problem with t/02zlib.t that was failing with redhat 8. | |
99 | ||
100 | 1.18 - 24 October 2002 | |
101 | ||
102 | * fixed a Win32 problem in t/02zlib.t by changing sysread to read. | |
103 | ||
104 | * zlib 1.0.5 & older doesn't have gzsetparams & gzeof. Added a new | |
105 | variable to config.in to flag an old version of zlib. Split | |
106 | out the tests for gzsetparams into t/05gzsetp.t | |
107 | ||
108 | 1.17 - 22 October 2002 | |
109 | ||
110 | * Moved the test to check the versions of libz & zlib.h into a separate | |
111 | file and added troubleshooting notes to README. | |
112 | ||
113 | * In gzopen, only attempt to call "tell" for normal files. | |
114 | ||
115 | * Broke changes out of README into Changes file. | |
116 | ||
117 | * Replaced internal use of Z_PARTIAL_FLUSH symbol with Z_SYNC_FLUSH. | |
118 | zlib.h says /* will be removed, use Z_SYNC_FLUSH instead */ | |
119 | ||
120 | * Added support for zlib functions inflateSync and deflateParams. | |
121 | ||
122 | * Added support for zlib functions gzeof and gzsetparams. | |
123 | ||
124 | * Added support for access to adler, total_in & total_out | |
125 | ||
126 | * The compress function can now take an optional parameter that | |
127 | allows the compression level to be specified. This mirrors the | |
128 | compress2 function available in zlib. | |
129 | ||
130 | * memGzip doesn't work properly with perl 5.8.0 when it is given | |
131 | UTF-8 data. Bug spotted by Andreas J. Koenig. | |
132 | ||
133 | * Added note about Linux zlib-devel RPM to README. | |
134 | ||
135 | * Fixed recursive build problem on win32 machines. | |
136 | ||
137 | * Fixed problem with the test harness on Mac OS X. | |
138 | Thanks to Carl Johan Berglund for reporting the problem and | |
139 | helping track it down. | |
140 | ||
141 | ||
142 | 1.16 - 13 December 2001 | |
143 | ||
144 | * Fixed bug in Makefile.PL that stopped "perl Makefile.PL PREFIX=..." | |
145 | working. | |
146 | ||
147 | 1.15 - 4th December 2001 | |
148 | ||
149 | * Changes a few types to get the module to build on 64-bit Solaris | |
150 | ||
151 | * Changed the up/downgrade logic to default to the older constructs, and | |
152 | to only call a downgrade if specifically requested. Some older versions | |
153 | of Perl were having problems with the in-place edit. | |
154 | ||
155 | * added the new XS constant code. | |
156 | ||
157 | 1.14 - 27th August 2001 | |
158 | ||
159 | * Memory overwrite bug fixed in "inflate". Kudos to Rob Simons for | |
160 | reporting the bug and to Anton Berezin for fixing it for me. | |
161 | ||
162 | 1.13 - 31st June 2001 | |
163 | ||
164 | * Make sure config.in is consistant when released. | |
165 | ||
166 | 1.12 - 28th April 2001 | |
167 | ||
168 | * Modified Makefile.PL to only enable the warnings pragma if | |
169 | using perl 5.6.1 or better. | |
170 | ||
171 | 1.11 - 17th February 2001 | |
172 | ||
173 | * Added logic in Makefile.PL to toggle between using $^W and | |
174 | the warnings pragma in the module. | |
175 | ||
176 | * The module, the examples & the test harness are now all strict | |
177 | & warnings clean. | |
178 | ||
179 | 1.10 - 5th February 2001 | |
180 | ||
181 | * fixed a bug in memGunzip. Used Z_ERR instead of Z_DATA_ERROR. | |
182 | ||
183 | 1.09 - 15th January 2001 | |
184 | ||
185 | * Silenced a few compiler warnings. | |
186 | ||
187 | * Updated zlib home site in README & Zlib.pm to www.info-zip.org | |
188 | ||
189 | * Minor typo in Zlib.pm - a link used AUTHORS instead of AUTHOR | |
190 | -- spotted by Frank Martini. | |
191 | ||
192 | * Mention Archive::Zip | |
193 | ||
194 | * added memGunzip. This is largely based on code provided by Jim Leonard. | |
195 | ||
196 | * $deflate->flush can now take an optional parameter. Valid | |
197 | values are Z_NO_FLUSH, Z_PARTIAL_FLUSH, Z_SYNC_FLUSH, Z_FULL_FLUSH | |
198 | and Z_FINISH. The default is Z_FINISH. | |
199 | ||
200 | 1.08 - 6 Jan 2000 | |
201 | ||
202 | * uncompress was clobbering its input parameter. Now it doesn't. | |
203 | This bug was spotted by Deven T. Corzine. | |
204 | ||
205 | * If a variable that only ever contained a number was given | |
206 | to compress or deflate, it would not be compressed properly. Now | |
207 | it will be coerced to a string and then compressed. This bug | |
208 | was spotted by Deven T. Corzine. | |
209 | ||
210 | 1.07 - 27 Nov 1999 | |
211 | ||
212 | * ANSI-ified the static functions in Zlib.xs | |
213 | ||
214 | * Added the ability to build zlib along with the module. | |
215 | This feature is 90% based on a Makefile provided by Gurusamy | |
216 | Sarathy. | |
217 | ||
218 | 1.06 - 20 Sep 1999 | |
219 | ||
220 | * Fixed a nasty problem where inflate could truncate the data | |
221 | returned. Thanks to Douglas Thomson <dougt@mugc.cc.monash.edu.au> | |
222 | for both spotting the problem and fixing the bug. | |
223 | ||
224 | * Added a note about the undocumented features in zlib that are | |
225 | required when accessing zip files. | |
226 | ||
227 | * gzclose will now get called automatically when the gzip object is | |
228 | destroyed. | |
229 | ||
230 | 1.05 - 3 June 1999 | |
231 | ||
232 | * Previous release used newSVpvn, which doesn't exist in 5.004_04 | |
233 | or earlier. Changed to use newSVpv instead. | |
234 | ||
235 | * The module needs Perl 5.004 or better, so updated the version | |
236 | checking in Zlib.pm and Makefile.PL | |
237 | ||
238 | 1.04 - 27 May 1999 | |
239 | ||
240 | * Bug 19990527.001: compress(undef) core dumps -- Fixed. | |
241 | ||
242 | 1.03 - 17 Mar 1999 | |
243 | ||
244 | * Updated to use the new PL_ symbols. | |
245 | Means the module can be built with Perl 5.005_5* | |
246 | ||
247 | 1.02 - 31 Jan 1999 | |
248 | ||
249 | * The return codes for gzread, gzreadline and gzwrite were | |
250 | documented incorrectly as returning a status code. | |
251 | ||
252 | * The test harness was missing a "gzclose". This caused problem | |
253 | showed up on an amiga. Thanks to Erik van Roode for reporting | |
254 | this one. | |
255 | ||
256 | * Patched zlib.t for OS/2. Thanks to Ilya Zakharevich for the patch. | |
257 | ||
258 | 1.01 - 23 Nov 1997 | |
259 | ||
260 | * A number of fixes to the test suite and the example scripts to | |
261 | allow them to work under win32. All courtesy of Gurusamy | |
262 | Sarathy. | |
263 | ||
264 | 1.00 - 14 Nov 1997 | |
265 | ||
266 | * Fixed crc32 & adler32. They were very broken. | |
267 | ||
268 | * The following functions can now take a scalar reference in | |
269 | place of a scalar for their buffer parameters: | |
270 | ||
271 | compress | |
272 | uncompress | |
273 | deflate | |
274 | inflate | |
275 | crc32 | |
276 | adler32 | |
277 | ||
278 | This should mean applications that make use of the module don't | |
279 | have to copy large buffers around. | |
280 | ||
281 | ||
282 | * Normally the inflate method consumes I<all> of the input buffer | |
283 | before returning. The exception to this is when inflate detects | |
284 | the end of the stream (Z_STREAM_END). In this case the input | |
285 | buffer need not be completely consumed. To allow processing of | |
286 | file formats that embed a deflation stream (e.g. zip, gzip), | |
287 | the inflate method now sets the buffer parameter to be what | |
288 | remains after inflation. | |
289 | ||
290 | When the return status is Z_STREAM_END, it will be what remains | |
291 | of the buffer (if any) after deflation. When the status is Z_OK | |
292 | it will be an empty string. | |
293 | ||
294 | This change means that the buffer parameter must be a lvalue. | |
295 | ||
296 | * Fixed crc32 and adler32. They were both very broken. | |
297 | ||
298 | * Added the Compress::Zlib::memGzip function. | |
299 | ||
300 | 0.5 - Confirmed that no changes were necessary for zlib 1.0.3, or 1.0.4. | |
301 | ||
302 | The optional parameters for deflateInit and inflateInit can now | |
303 | be specified as an associative array in addition to a reference | |
304 | to an associative array. They can also accept the -Name | |
305 | syntax. | |
306 | ||
307 | gzopen can now optionally take a reference to an open | |
308 | filehandle in place of a filename. In this case it will call | |
309 | gzdopen. | |
310 | ||
311 | Added gzstream example script. | |
312 | ||
313 | 0.4 - Upgrade to support zlib 0.99 | |
314 | ||
315 | Added dictionary interface. | |
316 | ||
317 | Fixed bug in gzreadline - previously it would keep returning | |
318 | the same buffer. This bug was reported by Helmut Jarausch | |
319 | ||
320 | Removed dependency to zutil.h and so dropped support for | |
321 | ||
322 | DEF_MEM_LEVEL (use MAX_MEM_LEVEL instead) | |
323 | DEF_WBITS (use MAX_WBITS instead) | |
324 | ||
325 | 0.3 - Added prototype specification. | |
326 | ||
327 | 0.2 - Fixed a minor allocation problem in Zlib.xs | |
328 | ||
329 | 0.1 - first alpha release. 2nd October 1995 |
