31 dnl Revision 1.17 2001/09/12 23:44:55 david__schmidt
32 dnl Mac OSX (Darwin) support added.
34 dnl Revision 1.16 2001/09/12 22:55:45 joergs
35 dnl AmigaOS support added.
37 dnl Revision 1.15 2001/09/12 17:28:59 david__schmidt
39 dnl OS/2 port: update autoconf'd support for the platform.
41 dnl Revision 1.14 2001/07/30 22:12:11 jongfoster
42 dnl Fixing Solaris build (I hope) and tidying up #defines:
43 dnl - All feature #defines are now of the form FEATURE_xxx
44 dnl - Permanently turned off WIN_GUI_EDIT
45 dnl - Permanently turned on WEBDAV and SPLIT_PROXY_ARGS
47 dnl Revision 1.13 2001/07/29 17:09:17 jongfoster
48 dnl Major changes to build system in order to fix these bugs:
49 dnl - pthreads under Linux was broken - changed -lpthread to -pthread
50 dnl - Compiling in MinGW32 mode under CygWin now correctly detects
51 dnl which shared libraries are available
52 dnl - Solaris support (?) (Not tested under Solaris yet)
54 dnl Revision 1.12 2001/07/25 19:16:27 oes
55 dnl Bumping version number to 2.9.8
57 dnl Revision 1.11 2001/07/21 18:00:07 jongfoster
58 dnl Bumping version number to 2.9.7
60 dnl Revision 1.10 2001/07/18 17:25:04 oes
63 dnl Revision 1.9 2001/07/15 19:45:13 jongfoster
64 dnl Added support for linking with POSIX threads library
66 dnl Revision 1.8 2001/07/15 17:54:29 jongfoster
67 dnl Renaming #define STATIC to STATIC_PCRE
68 dnl Adding new #define FEATURE_PTHREAD that will be used to enable
69 dnl POSIX threads support.
71 dnl Revision 1.7 2001/07/13 13:58:05 oes
72 dnl Completely reorganized the selection scheme for
73 dnl pcre, pcreposix, pcrs and gnu_regex:
75 dnl The presence of shared pcre, pcreposix or pcrs
76 dnl libraried is now autodetected. Additionally, the
77 dnl user can enforce using the built-in static variants
78 dnl by specifying --disable-dynamic-(pcre|pcrs).
79 dnl Care is taken to avoid that pcre is dyn, while pcreposix
80 dnl is static, if both are used and that pcrs is static if
83 dnl The choice between pcre, gnu or no regex for actionsfile
84 dnl URL matching is now via
85 dnl --(enable|disable)-regex-matching[=(gnu|pcre|no)] with the
86 dnl default being pcre.
88 dnl Revision 1.6 2001/06/29 21:56:40 oes
91 dnl Revision 1.5 2001/06/29 13:26:27 oes
92 dnl Introduced #define CODE_STATUS
94 dnl Revision 1.4 2001/05/29 09:50:24 jongfoster
95 dnl Unified blocklist/imagelist/permissionslist.
96 dnl File format is still under discussion, but the internal changes
97 dnl are (mostly) done.
99 dnl Also modified interceptor behaviour:
100 dnl - We now intercept all URLs beginning with one of the following
101 dnl prefixes (and *only* these prefixes):
103 dnl * http://ijbswa.sf.net/config/
104 dnl * http://ijbswa.sourceforge.net/config/
105 dnl - New interceptors "home page" - go to http://i.j.b/ to see it.
106 dnl - Internal changes so that intercepted and fast redirect pages
107 dnl are not replaced with an image.
108 dnl - Interceptors now have the option to send a binary page direct
109 dnl to the client. (i.e. ijb-send-banner uses this)
110 dnl - Implemented show-url-info interceptor. (Which is why I needed
111 dnl the above interceptors changes - a typical URL is
112 dnl "http://i.j.b/show-url-info?url=www.somesite.com/banner.gif".
113 dnl The previous mechanism would not have intercepted that, and
114 dnl if it had been intercepted then it then it would have replaced
115 dnl it with an image.)
117 dnl Revision 1.3 2001/05/22 18:46:04 oes
119 dnl - Enabled filtering banners by size rather than URL
120 dnl by adding patterns that replace all standard banner
121 dnl sizes with the "Junkbuster" gif to the re_filterfile
123 dnl - Enabled filtering WebBugs by providing a pattern
124 dnl which kills all 1x1 images
126 dnl - Added support for PCRE_UNGREEDY behaviour to pcrs,
127 dnl which is selected by the (nonstandard and therefore
128 dnl capital) letter 'U' in the option string.
129 dnl It causes the quantifiers to be ungreedy by default.
130 dnl Appending a ? turns back to greedy (!).
132 dnl - Added a new interceptor ijb-send-banner, which
133 dnl sends back the "Junkbuster" gif. Without imagelist or
134 dnl MSIE detection support, or if tinygif = 1, or the
135 dnl URL isn't recognized as an imageurl, a lame HTML
136 dnl explanation is sent instead.
138 dnl - Added new feature, which permits blocking remote
139 dnl script redirects and firing back a local redirect
141 dnl The feature is conditionally compiled, i.e. it
142 dnl can be disabled with --disable-fast-redirects,
143 dnl plus it must be activated by a "fast-redirects"
144 dnl line in the config file, has its own log level
145 dnl and of course wants to be displayed by show-proxy-args
146 dnl Note: Boy, all the #ifdefs in 1001 locations and
147 dnl all the fumbling with configure.in and acconfig.h
148 dnl were *way* more work than the feature itself :-(
150 dnl - Because a generic redirect template was needed for
151 dnl this, tinygif = 3 now uses the same.
153 dnl - Moved GIFs, and other static HTTP response templates
156 dnl - Some minor fixes
158 dnl - Removed some >400 CRs again (Jon, you really worked
161 dnl Revision 1.2 2001/05/20 01:21:20 jongfoster
162 dnl Version 2.9.4 checkin.
163 dnl - Merged popupfile and cookiefile, and added control over PCRS
164 dnl filtering, in new "permissionsfile".
165 dnl - Implemented LOG_LEVEL_FATAL, so that if there is a configuration
166 dnl file error you now get a message box (in the Win32 GUI) rather
167 dnl than the program exiting with no explanation.
168 dnl - Made killpopup use the PCRS MIME-type checking and HTTP-header
170 dnl - Removed tabs from "config"
171 dnl - Moved duplicated url parsing code in "loaders.c" to a new funcition.
172 dnl - Bumped up version number.
