Changes with Apache 2.0.55
+ *) Add ap_log_cerror() for logging messages associated with particular
+ client connections. [Jeff Trawick]
+
*) Correct mod_cgid's argv[0] so that the full path can be delved by the
invoked cgi application, to conform to the behavior of mod_cgi.
[Pradeep Kumar S <pradeep.smani gmail.com>]
PATCHES ACCEPTED TO BACKPORT FROM TRUNK:
[ start all new proposals below, under PATCHES PROPOSED. ]
- *) several changes to improve logging of connection-oriented errors, including
- ap_log_cerror() API (needs minor bump in addition to changes below)
- http://cvs.apache.org/viewcvs.cgi/httpd-2.0/server/core.c?r1=1.289&r2=1.291
- http://cvs.apache.org/viewcvs.cgi/httpd-2.0/server/log.c?r1=1.150&r2=1.151
- http://cvs.apache.org/viewcvs.cgi/httpd-2.0/include/http_log.h?r1=1.46&r2=1.48
- +1: trawick, stoddard, wrowe
- [wrowe notes that his previous objection is moot, based on security fixes
- applied between .44 and .54 - but -please- doxygen the version of Apache
- required in the API header note, for users who adopt this alternative.]
-
*) mod_cgi: Added API call and overload of detached field in
cgi_exec_info_t structure to support loading in current or new address
space for CGIs. The patch change how NetWare use cmdtype for
* ap_finalize_sub_req_protocol on Win32 and NetWare
* 20020903.9 (2.0.51-dev) create pcommands and initialize arrays before
* calling ap_setup_prelinked_modules
+ * 20020903.10 (2.0.55-dev) add ap_log_cerror()
