57 dnl AmigaOS support added.
59 dnl Revision 1.15 2001/09/12 17:28:59 david__schmidt
61 dnl OS/2 port: update autoconf'd support for the platform.
63 dnl Revision 1.14 2001/07/30 22:12:11 jongfoster
64 dnl Fixing Solaris build (I hope) and tidying up #defines:
65 dnl - All feature #defines are now of the form FEATURE_xxx
66 dnl - Permanently turned off WIN_GUI_EDIT
67 dnl - Permanently turned on WEBDAV and SPLIT_PROXY_ARGS
69 dnl Revision 1.13 2001/07/29 17:09:17 jongfoster
70 dnl Major changes to build system in order to fix these bugs:
71 dnl - pthreads under Linux was broken - changed -lpthread to -pthread
72 dnl - Compiling in MinGW32 mode under CygWin now correctly detects
73 dnl which shared libraries are available
74 dnl - Solaris support (?) (Not tested under Solaris yet)
76 dnl Revision 1.12 2001/07/25 19:16:27 oes
77 dnl Bumping version number to 2.9.8
79 dnl Revision 1.11 2001/07/21 18:00:07 jongfoster
80 dnl Bumping version number to 2.9.7
82 dnl Revision 1.10 2001/07/18 17:25:04 oes
85 dnl Revision 1.9 2001/07/15 19:45:13 jongfoster
86 dnl Added support for linking with POSIX threads library
88 dnl Revision 1.8 2001/07/15 17:54:29 jongfoster
89 dnl Renaming #define STATIC to STATIC_PCRE
90 dnl Adding new #define FEATURE_PTHREAD that will be used to enable
91 dnl POSIX threads support.
93 dnl Revision 1.7 2001/07/13 13:58:05 oes
94 dnl Completely reorganized the selection scheme for
95 dnl pcre, pcreposix, pcrs and gnu_regex:
97 dnl The presence of shared pcre, pcreposix or pcrs
98 dnl libraried is now autodetected. Additionally, the
99 dnl user can enforce using the built-in static variants
100 dnl by specifying --disable-dynamic-(pcre|pcrs).
101 dnl Care is taken to avoid that pcre is dyn, while pcreposix
102 dnl is static, if both are used and that pcrs is static if
105 dnl The choice between pcre, gnu or no regex for actionsfile
106 dnl URL matching is now via
107 dnl --(enable|disable)-regex-matching[=(gnu|pcre|no)] with the
108 dnl default being pcre.
110 dnl Revision 1.6 2001/06/29 21:56:40 oes
113 dnl Revision 1.5 2001/06/29 13:26:27 oes
114 dnl Introduced #define CODE_STATUS
116 dnl Revision 1.4 2001/05/29 09:50:24 jongfoster
117 dnl Unified blocklist/imagelist/permissionslist.
118 dnl File format is still under discussion, but the internal changes
119 dnl are (mostly) done.
121 dnl Also modified interceptor behaviour:
122 dnl - We now intercept all URLs beginning with one of the following
123 dnl prefixes (and *only* these prefixes):
125 dnl * http://ijbswa.sf.net/config/
126 dnl * http://ijbswa.sourceforge.net/config/
127 dnl - New interceptors "home page" - go to http://i.j.b/ to see it.
128 dnl - Internal changes so that intercepted and fast redirect pages
129 dnl are not replaced with an image.
130 dnl - Interceptors now have the option to send a binary page direct
131 dnl to the client. (i.e. ijb-send-banner uses this)
132 dnl - Implemented show-url-info interceptor. (Which is why I needed
133 dnl the above interceptors changes - a typical URL is
134 dnl "http://i.j.b/show-url-info?url=www.somesite.com/banner.gif".
135 dnl The previous mechanism would not have intercepted that, and
136 dnl if it had been intercepted then it then it would have replaced
137 dnl it with an image.)
139 dnl Revision 1.3 2001/05/22 18:46:04 oes
141 dnl - Enabled filtering banners by size rather than URL
142 dnl by adding patterns that replace all standard banner
143 dnl sizes with the "Junkbuster" gif to the re_filterfile
145 dnl - Enabled filtering WebBugs by providing a pattern
146 dnl which kills all 1x1 images
148 dnl - Added support for PCRE_UNGREEDY behaviour to pcrs,
149 dnl which is selected by the (nonstandard and therefore
150 dnl capital) letter 'U' in the option string.
151 dnl It causes the quantifiers to be ungreedy by default.
152 dnl Appending a ? turns back to greedy (!).
154 dnl - Added a new interceptor ijb-send-banner, which
155 dnl sends back the "Junkbuster" gif. Without imagelist or
156 dnl MSIE detection support, or if tinygif = 1, or the
157 dnl URL isn't recognized as an imageurl, a lame HTML
158 dnl explanation is sent instead.
160 dnl - Added new feature, which permits blocking remote
161 dnl script redirects and firing back a local redirect
163 dnl The feature is conditionally compiled, i.e. it
164 dnl can be disabled with --disable-fast-redirects,
165 dnl plus it must be activated by a "fast-redirects"
166 dnl line in the config file, has its own log level
167 dnl and of course wants to be displayed by show-proxy-args
168 dnl Note: Boy, all the #ifdefs in 1001 locations and
169 dnl all the fumbling with configure.in and acconfig.h
170 dnl were *way* more work than the feature itself :-(
172 dnl - Because a generic redirect template was needed for
173 dnl this, tinygif = 3 now uses the same.
175 dnl - Moved GIFs, and other static HTTP response templates
178 dnl - Some minor fixes
180 dnl - Removed some >400 CRs again (Jon, you really worked
183 dnl Revision 1.2 2001/05/20 01:21:20 jongfoster
184 dnl Version 2.9.4 checkin.
185 dnl - Merged popupfile and cookiefile, and added control over PCRS
186 dnl filtering, in new "permissionsfile".
187 dnl - Implemented LOG_LEVEL_FATAL, so that if there is a configuration
188 dnl file error you now get a message box (in the Win32 GUI) rather
189 dnl than the program exiting with no explanation.
190 dnl - Made killpopup use the PCRS MIME-type checking and HTTP-header
192 dnl - Removed tabs from "config"
193 dnl - Moved duplicated url parsing code in "loaders.c" to a new funcition.
194 dnl - Bumped up version number.
