UnZip, version 5.5, 17 February 2002
3
Features added (or removed):
6
- unzip.1: added documentation for the new Acorn NFS filetype features [SPC]
7
- generic (inflate.c, globals.h, fileio.c, unzpriv.h): integrated support of
8
Deflate64 for all ports with exception of MSDOS and OS/2 16-bit [SPC]
11
- added Deflate64 support to fUnZip [SPC]
12
- added Deflate64 support for 16-bit environments [SPC]
15
- SFX: made SFX_EXDIR default, added NO_SFXEXDIR option to allow switching
16
off the "-d exdir" support [SPC]
17
- OS2, WIN32: added presetting of file size for extracted files, to reduce
18
file fragmentation [Pavel Lastovicka, Kai Uwe Rommel, SPC]
19
- VMS, new functionality of -b option: when extracting to standard output
20
(-c or -p), -b switches to "binary piping mode" by disabling text data
24
- SFX: added simple "execute command after extraction" feature that uses a
25
command specification supplied with the Zip archive comment, controlled
26
by the CHEAP_SFX_AUTORUN compile time option [Paul Kienitz]
27
- SFX: slightly refined the CHEAP_SFX_AUTORUN code, switched off SFX_EXDIR
28
when CHEAP_SFX_AUTORUN is enabled, documented the new autorun feature [SPC]
29
- VMS: extended new "binary piping" functionality of -b switch to extraction
30
of archive entries with VMS attributes saved [SPC]
33
- extract.c, TestExtraField(): added crc32 check for PKVMS e.f. type [SPC]
34
- added real VMS-e.f. analysis for fool-proof detection of VMS "variable
35
length record" text files, enabled VMS_TEXT_CONV as default (but not for
37
- added support for optional ACORN_FTYPE_NFS feature to more OS that allow
38
long filenames and commas within filenames (BeOS, Novell, OS/2, Theos,
42
- extract.c, extract_or_test_entrylist(): added code for "stripping off
43
absolute path spec" when extracting [SPC]
46
- unzip.h, unzip.c; mapname() in all ports except CMS/MVS, Tandem, TOPS20:
47
added code to strip "../" path components from extracted names and new
48
option "-:" to allow deactivating this security feature; changed mapname()
49
calling interface to allow reporting warning error levels to caller [SPC]
50
- man/unzip.1: documented the new "-:" option [SPC]
51
- vms/cmdline.c etc.: added support for "-:" option to VMS DCL interface;
52
updated VMS help files with description of "-:" option [SPC]
53
- windll/windll.{c|txt}: modified handling of DCL struct's "ndflag" member
54
to allow setting the "-:" option through the windll interface [SPC]
55
- unzpriv.h, zipinfo.c: rudimentary support for recognizing PKWARE's new
56
"64-bit size specs" extra field [SPC]
59
- unix/Makefile: added separate makefile symbol INSTALL_PROGRAM for command
60
to install "binary" (compiled and linked) program files [Santiago Vila]
66
- all OS with Unix-compatible file attributes (Acorn, AosVS, BeOS, QDOS, Unix,
67
and others), mapattr(): corrected wrong masking expression in check for
68
missing directory attribute; added this check for ports where it was
69
still missing [Eric Siegerman, SPC]
70
- inflate.c: reorganized inner loop function for slight performance gain [SPC]
71
- explode.c: reorganized code (2 instead of 4 inner-loop function versions),
72
fixed memory leaks when get_tree() fails (added huft_free() calls) [SPC]
75
- inflate.c: some more optimizations (also resulting in easier readable code)
77
- unzip.c: revised work area size calculation in the WORK_MALLOC case, when
78
the decompression buffer is malloc'ed separately; removed suspicious
79
"one unit excess" allocation (8193 instead of 8192, not clear why this
80
was introduced in ancient times) [SPC]
81
- VMS - cvthelp.tpu, unzip_cli.help: reformatted CLI help file to show negated
82
form of negatable options on a separate line in the header of qualifier
83
descriptions [Hunter Goatley]
84
- generic: renamed version.h into unzvers.h (for better distinction from zip
85
sources) and updated all makefiles [SPC]
86

87
killed windll/unzver.h [SPC]
88
- api.c, global.h, extract.c, explode.c, inflate.c, unshrink.c: corrected
89
declarations of variables and function parameters holding redirected buffer
90
size (unsigned vs. ulg issues), added/modified appropiate type casts [SPC]
93
- most make procedures: unzipsfx compilation requires completely separate
94
object files (exception: crc32), because global structure is now different
95
from unzip setup (sfx: no Deflate64!) [Thom Schmidt, SPC]
96
- inflate.c: moved macro definitions for invalid huft code marker out of
97
"no ZLIB only" code part; it is used in huft_build() [Thomas Klausner]
98
- AMIGA, HUMAN68K: replaced specific mkGoff.c helper program sources by a more
99
generic gbloffs.c source (located in the top level directory); adapted
100
makefiles to this change [SPC]
101
- win32/win32: modified version() to recognize Borland C++ 5.5.1 [SPC]
102
- AMIGA: adapted assembler core routine flate.a to Deflate64 and the 64k
103
extraction buffer; adapted inflate setup to allow for 16bit ints in
104
an otherwise 32-bit environment [Paul Kienitz]
105
- human68k/flate.s: incorporated Paul's updates of amiga/flate.a in the
106
HUMAN68K source variant [SPC]
107

108
- unzpriv.h: updated exceptions of "made by FAT -> filename charset is OEM"
109
rule to now include the PKZIP 4.0 case [SPC]
110
- unzpriv.h, extract.c zipinfo.c: in preparation to multivolume support,
111
struct min_info has been extended to hold the entry's disk volume number
112
(to conserve space, hostnum & hostver members are shortened to uch) [SPC]
113
- extract.c, extract_or_test_files() function: isolated code of "second loop"
114
in a separate function, in preparation for multivolume support [SPC]
115
- os2/os2.c: use posix-style mkdir definition whenever __GNUC__ is defined,
116
for better compatibility with non-EMX gcc ports [Pavel Lastovicka, SPC]
117
- windll/windll.c: added missing SETLOCALE() initialization to Wiz_Init()
119
- WINDLL port: in windll.c, changed FreeDllMem() scope into static; tried
120
to clarify in windll.txt that Wiz_SetOpts() and Wiz_Unzip() must be
121
used as a pair of functions [SPC]
122
- VMS: removed unused and undocumented /TYPE switch from CLI interface [SPC]
125
- unix/Makefile: correction for LynxOS target [Mark Clayton]
126
- extract.c: synchronized extract_or_test_entrylist() prototype declaration
127
for the SET_DIR_ATTRIB case with actually used function interface [SPC]
128
- vms/descrip.mms: corrected typo in match_$O rule [Michael Lemke]
129
- vms/vms.c: limit buffer size for single block output to less than 64k
130
(RMS limit on VAX); corrected record overflow checks to use the right
131
RMS limit of (32k-1) [Mike Freeman, SPC]
132
- unzver.h: renamed COMPANY_NAME symbol to IZ_COMPANY_NAME, check for
133
symbol being already defined; restrict definition of OS/2-DLL specific
134
version symbols to OS/2 port [Mike White, SPC]
135
- windll/uzexampl.c: corrected inclusion path of unzver.h [Mike White]
136
- acorn/GMakefile: need NO_STRNICMP, fixed missing renaming of version.h
137
into unzvers.h [Andy Wingate]
138

139
multiple of 512 is achieved by ANDing with ~511 instead of ~512 [SPC]
142
- vms/vms.c: added missing -c handling in WriteBuffer() to make the "-b"
143
binary piping mode functional [SPC]
146

147
version 5.42 due to incomplete change by SPC [Michael Ringe, SPC]

154
"escaped" by doubling them, to prevent compiler warnings for newest
155
DEC (COMPAQ) C versions [Dirk Munk, SPC]

186
into the private main header unzpriv.h [SPC]
187
- extract.c, fileio.c: extended UNIXBACKUP optional functionality to create
