1) Fix an issue where because of the reordering of transform_request
and process_cgi, the cgi-script name was being cut off
by one character (transform_request for some reason
cuts off the leading '/' for the file name as part of its
processing). As an 'easy' fix, simply re-add the '/' to the
front of the filename, which means that we don't have to
mess with the logic that sometimes adds +1 and sometimes doesn't.
2) Work around ridiculous bug in PHP reported by lukem in 2004,
but stubbornly never fixed by the PHP maintainers:
Change the SCRIPT_NAME and SCRIPT_FILENAME variables
to contain the file name only, not the query if one exists.
Having the query in SCRIPT_FILENAME causes php-cgi to not
work, as per the bug information here:
http://bugs.php.net/bug.php?id=28227
3) Fix a memory leak because URL wasn't being freed.
CGI handling, including bin/40355 . There are two main changes here:
1) call process_cgi() after transform_request(), not before. Now it is
possible to have a default cgi handler catch a request for a path that
was produced by transformation, e.g. by index generation -- so now the
index can be "generated" by a CGI if that is what the user desires.
2) More clearly distinguish "file" from "query" portions of the request
URL, so we do not feed ?-suffixed "arguments" to plain files, fail to
match filename extensions due to ?-suffixes, etc.
After this change, there are only two cases which use the "query"
portion of the request (the portion after the ?):
a) A redirect issued by HTTPD will redirect to the new file, but
with the same query string.
b) process_cgi() will, of course continue to use the query string.
- remove unused write_str var
+ move header parsing to new function separation of parsing vs processing
+ alter some variable names to avoid confusion between header value and
header name (caused breakage with previous rev)
(i.e. free(): warning: modified (chunk-) pointer))
+ don't leak memory for ptr actually returned from strdup()
+ don't strdup() if we don't have to
+ don't break without free() if we did strdup()
+ as well as freeing h_value also free the header.
