0.9.0
|
|
|
4 |
~~~~~
|
|
|
5 |
First version.
|
|
|
6 |
|
|
|
7 |
|
|
|
8 |
0.9.0a
|
|
|
9 |
~~~~~~
|
|
|
10 |
Removed 'ranlib' from Makefile, since most modern Unix-es
|
|
|
11 |
don't need it, or even know about it.
|
|
|
12 |
|
|
|
13 |
|
|
|
14 |
0.9.0b
|
|
|
15 |
~~~~~~
|
|
|
16 |
Fixed a problem with error reporting in bzip2.c. This does not effect
|
|
|
17 |
the library in any way. Problem is: versions 0.9.0 and 0.9.0a (of the
|
|
|
18 |
program proper) compress and decompress correctly, but give misleading
|
|
|
19 |
error messages (internal panics) when an I/O error occurs, instead of
|
|
|
20 |
reporting the problem correctly. This shouldn't give any data loss
|
|
|
21 |
(as far as I can see), but is confusing.
|
|
|
22 |
|
|
|
23 |
Made the inline declarations disappear for non-GCC compilers.
|
|
|
24 |
|
|
|
25 |
|
|
|
26 |
0.9.0c
|
|
|
27 |
~~~~~~
|
|
|
28 |
Fixed some problems in the library pertaining to some boundary cases.
|
|
|
29 |
This makes the library behave more correctly in those situations. The
|
|
|
30 |
fixes apply only to features (calls and parameters) not used by
|
|
|
31 |
bzip2.c, so the non-fixedness of them in previous versions has no
|
|
|
32 |
effect on reliability of bzip2.c.
|
|
|
33 |
|
|
|
34 |
In bzlib.c:
|
|
|
35 |
* made zero-length BZ_FLUSH work correctly in bzCompress().
|
|
|
36 |
* fixed bzWrite/bzRead to ignore zero-length requests.
|
|
|
37 |
* fixed bzread to correctly handle read requests after EOF.
|
|
|
38 |
* wrong parameter order in call to bzDecompressInit in
|
|
|
39 |
bzBuffToBuffDecompress. Fixed.
|
|
|
40 |
|
|
|
41 |
In compress.c:
|
|
|
42 |
* changed setting of nGroups in sendMTFValues() so as to
|
|
|
43 |
do a bit better on small files. This _does_ effect
|
|
|
44 |
bzip2.c.
|
|
|
45 |
|
|
|
46 |
|
|
|
47 |
0.9.5a
|
|
|
48 |
~~~~~~
|
|
|
49 |
Major change: add a fallback sorting algorithm (blocksort.c)
|
|
|
50 |
to give reasonable behaviour even for very repetitive inputs.
|
|
|
51 |
Nuked --repetitive-best and --repetitive-fast since they are
|
|
|
52 |
no longer useful.
|
|
|
53 |
|
|
|
54 |
Minor changes: mostly a whole bunch of small changes/
|
|
|
55 |
bugfixes in the driver (bzip2.c). Changes pertaining to the
|
|
|
56 |
user interface are:
|
|
|
57 |
|
|
|
58 |
allow decompression of symlink'd files to stdout
|
|
|
59 |
decompress/test files even without .bz2 extension
|
|
|
60 |
give more accurate error messages for I/O errors
|
|
|
61 |
when compressing/decompressing to stdout, don't catch control-C
|
|
|
62 |
read flags from BZIP2 and BZIP environment variables
|
|
|
63 |
decline to break hard links to a file unless forced with -f
|
|
|
64 |
allow -c flag even with no filenames
|
|
|
65 |
preserve file ownerships as far as possible
|
|
|
66 |
make -s -1 give the expected block size (100k)
|
|
|
67 |
add a flag -q --quiet to suppress nonessential warnings
|
|
|
68 |
stop decoding flags after --, so files beginning in - can be handled
|
|
|
69 |
resolved inconsistent naming: bzcat or bz2cat ?
|
|
|
70 |
bzip2 --help now returns 0
|
|
|
71 |
|
|
|
72 |
Programming-level changes are:
|
|
|
73 |
|
|
|
74 |
fixed syntax error in GET_LL4 for Borland C++ 5.02
|
|
|
75 |
let bzBuffToBuffDecompress return BZ_DATA_ERROR{_MAGIC}
|
|
|
76 |
fix overshoot of mode-string end in bzopen_or_bzdopen
|
|
|
77 |
wrapped bzlib.h in #ifdef __cplusplus ... extern "C" { ... }
|
|
|
78 |
close file handles under all error conditions
|
|
|
79 |
added minor mods so it compiles with DJGPP out of the box
|
|
|
80 |
fixed Makefile so it doesn't give problems with BSD make
|
|
|
81 |
fix uninitialised memory reads in dlltest.c
|
|
|
82 |
|
|
|
83 |
0.9.5b
|
|
|
84 |
~~~~~~
|
|
|
85 |
Open stdin/stdout in binary mode for DJGPP.
|
|
|
86 |
|
|
|
87 |
0.9.5c
|
|
|
88 |
~~~~~~
|
|
|
89 |
Changed BZ_N_OVERSHOOT to be ... + 2 instead of ... + 1. The + 1
|
|
|
90 |
version could cause the sorted order to be wrong in some extremely
|
|
|
91 |
obscure cases. Also changed setting of quadrant in blocksort.c.
|
|
|
92 |
|
|
|
93 |
0.9.5d
|
|
|
94 |
~~~~~~
|
|
|
95 |
The only functional change is to make bzlibVersion() in the library
|
|
|
96 |
return the correct string. This has no effect whatsoever on the
|
|
|
97 |
functioning of the bzip2 program or library. Added a couple of casts
|
|
|
98 |
so the library compiles without warnings at level 3 in MS Visual
|
|
|
99 |
Studio 6.0. Included a Y2K statement in the file Y2K_INFO. All other
|
|
|
100 |
changes are minor documentation changes.
|
|
|
101 |
|
|
|
102 |
1.0
|
|
|
103 |
~~~
|
|
|
104 |
Several minor bugfixes and enhancements:
|
|
|
105 |
|
|
|
106 |
* Large file support. The library uses 64-bit counters to
|
|
|
107 |
count the volume of data passing through it. bzip2.c
|
|
|
108 |
is now compiled with -D_FILE_OFFSET_BITS=64 to get large
|
|
|
109 |
file support from the C library. -v correctly prints out
|
|
|
110 |
file sizes greater than 4 gigabytes. All these changes have
|
|
|
111 |
been made without assuming a 64-bit platform or a C compiler
|
|
|
112 |
which supports 64-bit ints, so, except for the C library
|
|
|
113 |
aspect, they are fully portable.
|
|
|
114 |
|
|
|
115 |
* Decompression robustness. The library/program should be
|
|
|
116 |
robust to any corruption of compressed data, detecting and
|
|
|
117 |
handling _all_ corruption, instead of merely relying on
|
|
|
118 |
the CRCs. What this means is that the program should
|
|
|
119 |
never crash, given corrupted data, and the library should
|
|
|
120 |
always return BZ_DATA_ERROR.
|
|
|
121 |
|
|
|
122 |
* Fixed an obscure race-condition bug only ever observed on
|
|
|
123 |
Solaris, in which, if you were very unlucky and issued
|
|
|
124 |
control-C at exactly the wrong time, both input and output
|
|
|
125 |
files would be deleted.
|
|
|
126 |
|
|
|
127 |
* Don't run out of file handles on test/decompression when
|
|
|
128 |
large numbers of files have invalid magic numbers.
|
|
|
129 |
|
|
|
130 |
* Avoid library namespace pollution. Prefix all exported
|
|
|
131 |
symbols with BZ2_.
|
|
|
132 |
|
|
|
133 |
* Minor sorting enhancements from my DCC2000 paper.
|
|
|
134 |
|
|
|
135 |
* Advance the version number to 1.0, so as to counteract the
|
|
|
136 |
(false-in-this-case) impression some people have that programs
|
|
|
137 |
with version numbers less than 1.0 are in someway, experimental,
|
|
|
138 |
pre-release versions.
|
|
|
139 |
|
|
|
140 |
* Create an initial Makefile-libbz2_so to build a shared library.
|
|
|
141 |
Yes, I know I should really use libtool et al ...
|
|
|
142 |
|
|
|
143 |
* Make the program exit with 2 instead of 0 when decompression
|
|
|
144 |
fails due to a bad magic number (ie, an invalid bzip2 header).
|
|
|
145 |
Also exit with 1 (as the manual claims :-) whenever a diagnostic
|
|
|
146 |
message would have been printed AND the corresponding operation
|
|
|
147 |
is aborted, for example
|
|
|
148 |
bzip2: Output file xx already exists.
|
|
|
149 |
When a diagnostic message is printed but the operation is not
|
|
|
150 |
aborted, for example
|
|
|
151 |
bzip2: Can't guess original name for wurble -- using wurble.out
|
|
|
152 |
then the exit value 0 is returned, unless some other problem is
|
|
|
153 |
also detected.
|
|
|
154 |
|
|
|
155 |
I think it corresponds more closely to what the manual claims now.
|
|
|
156 |
|
|
|
157 |
|
|
|
158 |
1.0.1
|
|
|
159 |
~~~~~
|
|
|
160 |
* Modified dlltest.c so it uses the new BZ2_ naming scheme.
|
|
|
161 |
* Modified makefile-msc to fix minor build probs on Win2k.
|
|
|
162 |
* Updated README.COMPILATION.PROBLEMS.
|
|
|
163 |
|
|
|
164 |
There are no functionality changes or bug fixes relative to version
|
|
|
165 |
1.0.0. This is just a documentation update + a fix for minor Win32
|
|
|
166 |
build problems. For almost everyone, upgrading from 1.0.0 to 1.0.1 is
|
|
|
167 |
utterly pointless. Don't bother.
