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