8 * Purpose : zalloc, hash_string, safe_strerror, strcmpic,
9 * strncmpic, and MinGW32 strdup functions. These are
10 * each too small to deserve their own file but don't
11 * really fit in any other file.

40 * Revision 1.29 2007/09/09 18:20:20 fabiankeil
41 * Turn privoxy_strlcpy() into a function and try to work with
42 * b0rked snprintf() implementations too. Reported by icmp30.
44 * Revision 1.28 2007/05/11 11:48:16 fabiankeil
45 * - Delete strsav() which was replaced
46 * by string_append() years ago.
47 * - Add a strlcat() look-alike.
48 * - Use strlcat() and strlcpy() in those parts
49 * of the code that are run on unixes.
51 * Revision 1.27 2007/04/09 17:48:51 fabiankeil
52 * Check for HAVE_SNPRINTF instead of __OS2__
53 * before including the portable snprintf() code.
55 * Revision 1.26 2007/04/08 17:04:51 fabiankeil
56 * Add macro for strlcpy() in case the libc lacks it.
58 * Revision 1.25 2007/01/18 15:03:20 fabiankeil
59 * Don't include replacement timegm() if
60 * putenv() or tzset() isn't available.
62 * Revision 1.24 2006/08/17 17:15:10 fabiankeil
63 * - Back to timegm() using GnuPG's replacement if necessary.
64 * Using mktime() and localtime() could add a on hour offset if
65 * the randomize factor was big enough to lead to a summer/wintertime
68 * - Removed now-useless Privoxy 3.0.3 compatibility glue.
70 * - Moved randomization code into pick_from_range().
72 * - Changed parse_header_time definition.
73 * time_t isn't guaranteed to be signed and
74 * if it isn't, -1 isn't available as error code.
75 * Changed some variable types in client_if_modified_since()
76 * because of the same reason.
78 * Revision 1.23 2006/07/18 14:48:47 david__schmidt
79 * Reorganizing the repository: swapping out what was HEAD (the old 3.1 branch)
80 * with what was really the latest development (the v_3_0_branch branch)
82 * Revision 1.21 2002/04/26 12:55:38 oes
83 * New function string_toupper
85 * Revision 1.20 2002/03/26 22:29:55 swa
86 * we have a new homepage!
88 * Revision 1.19 2002/03/24 13:25:43 swa
89 * name change related issues
91 * Revision 1.18 2002/03/07 03:46:17 oes
92 * Fixed compiler warnings
94 * Revision 1.17 2002/03/04 18:28:32 oes
95 * Deleted deletePidFile, played syleguide police
97 * Revision 1.16 2002/01/21 00:53:36 jongfoster
98 * Adding string_join()
100 * Revision 1.15 2001/12/30 14:07:32 steudten
101 * - Add signal handling (unix)
102 * - Add SIGHUP handler (unix)
103 * - Add creation of pidfile (unix)
104 * - Add action 'top' in rc file (RH)
105 * - Add entry 'SIGNALS' to manpage
106 * - Add exit message to logfile (unix)
108 * Revision 1.14 2001/11/05 21:43:48 steudten
109 * Add global var 'basedir' for unix os.
111 * Revision 1.13 2001/10/29 03:48:10 david__schmidt
112 * OS/2 native needed a snprintf() routine. Added one to miscutil, brackedted
113 * by and __OS2__ ifdef.
115 * Revision 1.12 2001/10/23 21:27:50 jongfoster
116 * Standardising error codes in string_append
117 * make_path() no longer adds '\\' if the dir already ends in '\\' (this
118 * is just copying a UNIX-specific fix to the Windows-specific part)
120 * Revision 1.11 2001/10/14 22:02:57 jongfoster
121 * New function string_append() which is like strsav(), but running
122 * out of memory isn't automatically FATAL.
124 * Revision 1.10 2001/09/20 13:34:09 steudten
126 * change long to int for prototype hash_string()
128 * Revision 1.9 2001/07/29 18:43:08 jongfoster
129 * Changing #ifdef _FILENAME_H to FILENAME_H_INCLUDED, to conform to
132 * Revision 1.8 2001/06/29 13:32:14 oes
133 * Removed logentry from cancelled commit
135 * Revision 1.7 2001/06/05 22:32:01 jongfoster
136 * New function make_path() to splice directory and file names together.
138 * Revision 1.6 2001/06/03 19:12:30 oes
139 * introduced bindup()
141 * Revision 1.5 2001/06/01 10:31:51 oes
142 * Added character class matching to trivimatch; renamed to simplematch
144 * Revision 1.4 2001/05/31 17:32:31 oes
146 * - Enhanced domain part globbing with infix and prefix asterisk
147 * matching and optional unanchored operation
149 * Revision 1.3 2001/05/29 23:10:09 oes
152 * - Introduced chomp()
153 * - Moved strsav() from showargs to miscutil
155 * Revision 1.2 2001/05/29 09:50:24 jongfoster
156 * Unified blocklist/imagelist/permissionslist.
157 * File format is still under discussion, but the internal changes
160 * Also modified interceptor behaviour:
161 * - We now intercept all URLs beginning with one of the following
162 * prefixes (and *only* these prefixes):
164 * * http://ijbswa.sf.net/config/
165 * * http://ijbswa.sourceforge.net/config/
166 * - New interceptors "home page" - go to http://i.j.b/ to see it.
167 * - Internal changes so that intercepted and fast redirect pages
168 * are not replaced with an image.
169 * - Interceptors now have the option to send a binary page direct
170 * to the client. (i.e. ijb-send-banner uses this)
171 * - Implemented show-url-info interceptor. (Which is why I needed
172 * the above interceptors changes - a typical URL is
173 * "http://i.j.b/show-url-info?url=www.somesite.com/banner.gif".
174 * The previous mechanism would not have intercepted that, and
175 * if it had been intercepted then it then it would have replaced
178 * Revision 1.1.1.1 2001/05/15 13:59:00 oes
179 * Initial import of version 2.9.3 source tree
