100 dnl Revision 1.14 2001/07/30 22:12:11 jongfoster
101 dnl Fixing Solaris build (I hope) and tidying up #defines:
102 dnl - All feature #defines are now of the form FEATURE_xxx
103 dnl - Permanently turned off WIN_GUI_EDIT
104 dnl - Permanently turned on WEBDAV and SPLIT_PROXY_ARGS
106 dnl Revision 1.13 2001/07/29 17:09:17 jongfoster
107 dnl Major changes to build system in order to fix these bugs:
108 dnl - pthreads under Linux was broken - changed -lpthread to -pthread
109 dnl - Compiling in MinGW32 mode under CygWin now correctly detects
110 dnl which shared libraries are available
111 dnl - Solaris support (?) (Not tested under Solaris yet)
113 dnl Revision 1.12 2001/07/25 19:16:27 oes
114 dnl Bumping version number to 2.9.8
116 dnl Revision 1.11 2001/07/21 18:00:07 jongfoster

123 dnl Added support for linking with POSIX threads library
125 dnl Revision 1.8 2001/07/15 17:54:29 jongfoster
126 dnl Renaming #define STATIC to STATIC_PCRE
127 dnl Adding new #define FEATURE_PTHREAD that will be used to enable
128 dnl POSIX threads support.
130 dnl Revision 1.7 2001/07/13 13:58:05 oes
131 dnl Completely reorganized the selection scheme for
132 dnl pcre, pcreposix, pcrs and gnu_regex:
134 dnl The presence of shared pcre, pcreposix or pcrs
135 dnl libraried is now autodetected. Additionally, the
136 dnl user can enforce using the built-in static variants
137 dnl by specifying --disable-dynamic-(pcre|pcrs).
138 dnl Care is taken to avoid that pcre is dyn, while pcreposix
139 dnl is static, if both are used and that pcrs is static if
142 dnl The choice between pcre, gnu or no regex for actionsfile
143 dnl URL matching is now via
144 dnl --(enable|disable)-regex-matching[=(gnu|pcre|no)] with the
145 dnl default being pcre.
147 dnl Revision 1.6 2001/06/29 21:56:40 oes
150 dnl Revision 1.5 2001/06/29 13:26:27 oes
151 dnl Introduced #define CODE_STATUS
153 dnl Revision 1.4 2001/05/29 09:50:24 jongfoster
154 dnl Unified blocklist/imagelist/permissionslist.
155 dnl File format is still under discussion, but the internal changes
156 dnl are (mostly) done.
158 dnl Also modified interceptor behaviour:
159 dnl - We now intercept all URLs beginning with one of the following
160 dnl prefixes (and *only* these prefixes):
162 dnl * http://ijbswa.sf.net/config/
163 dnl * http://ijbswa.sourceforge.net/config/
164 dnl - New interceptors "home page" - go to http://i.j.b/ to see it.
165 dnl - Internal changes so that intercepted and fast redirect pages
166 dnl are not replaced with an image.
167 dnl - Interceptors now have the option to send a binary page direct
168 dnl to the client. (i.e. ijb-send-banner uses this)
169 dnl - Implemented show-url-info interceptor. (Which is why I needed
170 dnl the above interceptors changes - a typical URL is
171 dnl "http://i.j.b/show-url-info?url=www.somesite.com/banner.gif".
172 dnl The previous mechanism would not have intercepted that, and
173 dnl if it had been intercepted then it then it would have replaced
174 dnl it with an image.)
176 dnl Revision 1.3 2001/05/22 18:46:04 oes
178 dnl - Enabled filtering banners by size rather than URL
179 dnl by adding patterns that replace all standard banner
180 dnl sizes with the "Junkbuster" gif to the re_filterfile
182 dnl - Enabled filtering WebBugs by providing a pattern
183 dnl which kills all 1x1 images
185 dnl - Added support for PCRE_UNGREEDY behaviour to pcrs,
186 dnl which is selected by the (nonstandard and therefore
187 dnl capital) letter 'U' in the option string.
188 dnl It causes the quantifiers to be ungreedy by default.
189 dnl Appending a ? turns back to greedy (!).
191 dnl - Added a new interceptor ijb-send-banner, which
192 dnl sends back the "Junkbuster" gif. Without imagelist or
193 dnl MSIE detection support, or if tinygif = 1, or the
194 dnl URL isn't recognized as an imageurl, a lame HTML
195 dnl explanation is sent instead.
197 dnl - Added new feature, which permits blocking remote
198 dnl script redirects and firing back a local redirect
200 dnl The feature is conditionally compiled, i.e. it
201 dnl can be disabled with --disable-fast-redirects,
202 dnl plus it must be activated by a "fast-redirects"
203 dnl line in the config file, has its own log level
204 dnl and of course wants to be displayed by show-proxy-args
205 dnl Note: Boy, all the #ifdefs in 1001 locations and
206 dnl all the fumbling with configure.in and acconfig.h
207 dnl were *way* more work than the feature itself :-(
209 dnl - Because a generic redirect template was needed for
210 dnl this, tinygif = 3 now uses the same.
212 dnl - Moved GIFs, and other static HTTP response templates
215 dnl - Some minor fixes
217 dnl - Removed some >400 CRs again (Jon, you really worked
220 dnl Revision 1.2 2001/05/20 01:21:20 jongfoster
221 dnl Version 2.9.4 checkin.
222 dnl - Merged popupfile and cookiefile, and added control over PCRS
223 dnl filtering, in new "permissionsfile".
224 dnl - Implemented LOG_LEVEL_FATAL, so that if there is a configuration
225 dnl file error you now get a message box (in the Win32 GUI) rather
226 dnl than the program exiting with no explanation.
227 dnl - Made killpopup use the PCRS MIME-type checking and HTTP-header
229 dnl - Removed tabs from "config"
230 dnl - Moved duplicated url parsing code in "loaders.c" to a new funcition.
231 dnl - Bumped up version number.
