*
* File : $Source: /cvsroot/ijbswa/current/jbsockets.c,v $
*
* Revisions :
* $Log: jbsockets.c,v $
- * Revision 1.8 2001/06/03 11:03:48 oes
- * Makefile/in
+ * Revision 1.23 2002/03/05 00:36:01 jongfoster
+ * Fixing bug 514988 - unable to restart JunkBuster
*
- * introduced cgi.c
+ * Revision 1.22 2002/03/04 02:08:02 david__schmidt
+ * Enable web editing of actions file on OS/2 (it had been broken all this time!)
*
- * actions.c:
+ * Revision 1.21 2002/01/09 14:32:33 oes
+ * Added support for gethostbyname_r and gethostbyaddr_r.
*
- * adapted to new enlist_unique arg format
+ * Revision 1.20 2001/11/16 00:48:48 jongfoster
+ * Enabling duplicate-socket detection for all platforms, not
+ * just Win32.
*
- * conf loadcfg.c
+ * Revision 1.19 2001/10/25 03:40:47 david__schmidt
+ * Change in porting tactics: OS/2's EMX porting layer doesn't allow multiple
+ * threads to call select() simultaneously. So, it's time to do a real, live,
+ * native OS/2 port. See defines for __EMX__ (the porting layer) vs. __OS2__
+ * (native). Both versions will work, but using __OS2__ offers multi-threading.
*
- * introduced confdir option
+ * Revision 1.18 2001/09/21 23:02:02 david__schmidt
+ * Cleaning up 2 compiler warnings on OS/2.
*
- * filters.c filtrers.h
+ * Revision 1.17 2001/09/13 20:11:46 jongfoster
+ * Fixing 2 compiler warnings under Win32
*
- * extracted-CGI relevant stuff
+ * Revision 1.16 2001/07/30 22:08:36 jongfoster
+ * Tidying up #defines:
+ * - All feature #defines are now of the form FEATURE_xxx
+ * - Permanently turned off WIN_GUI_EDIT
+ * - Permanently turned on WEBDAV and SPLIT_PROXY_ARGS
*
- * jbsockets.c
+ * Revision 1.15 2001/07/29 17:40:43 jongfoster
+ * Fixed compiler warning by adding a cast
*
- * filled comment
+ * Revision 1.14 2001/07/18 13:47:59 oes
+ * Eliminated dirty hack for getsockbyname()
*
- * jcc.c
+ * Revision 1.13 2001/07/15 13:56:57 jongfoster
+ * Removing unused local variable.
*
- * support for new cgi mechansim
+ * Revision 1.12 2001/07/01 17:04:11 oes
+ * Bugfix: accept_connection no longer uses the obsolete hstrerror() function
*
- * list.c list.h
+ * Revision 1.11 2001/06/29 21:45:41 oes

- * functions for new list type: "map"
- * extended enlist_unique
+ * Revision 1.10 2001/06/29 13:29:15 oes
+ * - Added remote (server) host IP to csp->http->host_ip_addr_str
+ * - Added detection of local socket IP and fqdn
+ * - Removed logentry from cancelled commit
*
