HTTPD PROXY STATUS:
Last modified at [$Date: 2001/10/05 08:57:18 $]
Release:
intended for 1.3/2.0 release date
httpd 1.3.x)
Source for HTTP/1.1 mod_proxy is now available
in httpd-proxy/module-1.0/ via CVS
Note: this code now maintains binary compatibility
CVS snapshots of HTTP/1.1 proxy + apache 1.3-current are at
http://cvs.apache.org/builds/httpd-proxy/
httpd 2.0)
work ongoing
Graham's patches for httpd-2.0 committed
merged back into httpd-2.0 module
CVS snapshots of httpd-2.0 (including apr & apr-util & buildconf'ed) are at
http://cvs.apache.org/builds/httpd-proxy/
httpd 2.0+)
email block diagrams exchanged, and clarified a little
talked about these at ApacheCon AFA a new proxy and cache design
got good feedback from Theo and Ian
httpd 2.1)
TBD - create new development subdir, snapshots
RELEASE SHOWSTOPPERS:
a), b), c) below.
2.0
* problems with akamai proxies - under investigation
This problem is fixed on FreeBSD 4.3 and Linux 2.2 as of 6/26/01
* Inter-module dependencies cause the proxy to act up on AIX as a
DSO. Hack in place currently - need to clean this up.
* Remove the last bits of non-threadsafe code. inet_ntoa springs to mind.
RELEASE NON-SHOWSTOPPERS BUT WOULD BE REAL NICE TO WRAP THESE UP:
1.3.x
* Ronald Tschaler's patch to mod_proxy to allow other modules to
set headers too (needed by mod_auth_digest)
Message-ID: <19...@chill.innovation.ch>
Status: TBD
* announce to current-testers@ to get some looking at
* possibly to fold this into a later release (1.3.20++?)
currently being maintained as a separate code base + patch
* Bill Rowe's suggested fix for Win32 - done
* Kwindla Kramer's patches for downstream cache control
Message-ID: <15...@khk.allafrica.com>
Status: under consideration
* Luis Londono's mod_ssl post patch to fix up after mod_ssl installed
Message-ID: <01...@nisbic.com>
Status: this needs to go to the mod_ssl guys
2.0
* announce to current-testers@ to get some looking at
* Audit all calls to ap_[get,pass]_brigade, and check that
the return values are inspected and acted upon correctly.
As it is, we blithely ignore FAR too many of these calls.
General return code audit would be nice too...
* problems when streaming mp3 from live365.com, and audio stream dies
and reconnects - we seem to be hanging on the stream close, since
the client (iTunes) may not be actually closing the connection
(not believed to be an HTTP proxy problem)
* Remove any and all code tied to IPv4, for IPv6 compatibility. Go looking
for in_addr.
* Possibly set SO_REUSEPORT in the ftp proxy, as some ftp servers may need
it.
* Possible proxy waiting scoreboard state
2.0+
* none
Other known bugs that need fixing:
1.3.x
* many PRs to be cleaned up - proceeding
2.0
* none
2.0+
* none
Other features that need writing:
1.3.x
* mod_rewrite and possibly mod_include cleanup
2.0
* none
2.0+
* none
Documentation that needs editing:
1.3.x
* mod_proxy.html (needs a once-over)
2.0
* mod_proxy.html
2.0+
* none
Available Patches:
1.3.x
* PR#3489 patch for NoCache/mod_rewrite problem
2.0
* none
2.0+
* none
Open Issues:
* Eventual reintegration into httpd-2.0. The basic criteria are:
a) The code compiles and runs as often as any code in the tree
b) The functionality makes sense for an HTTP proxy
c) There is an active maintainer who is or can become an ASF
member.
* announce to current-testers@ to get some looking at (1.3/2.0 both)
* announce for inclusion vote and Graham commit privs - done (sort of)
Problem reports to clean up (finally):
NOTE: These are pulled directly from httpd-2.0's STATUS.
* PR#362: mod_proxy
Mod_proxy doesn't allow change of error pages
Status:
* PR#440: mod_proxy
Proxy doesn't deliver documents if not connected
Status:
* PR#534: mod_proxy
proxy converts ~name to %7Ename when name starts with a dot (.)
Status:
* PR#612: mod_proxy
Proxy FTP Authentication Fails
Status:
* PR#700: mod_proxy
Proxy doesn't do links right for OpenVMS files through ftp:
Status:
* PR#980: mod_proxy
Controlling Access to Remote Proxies would be nice...
Status:
* PR#994: mod_proxy
Adding authentication "on the fly" through the proxy module
Status:

mod_proxy to support persistent conns?
Status:

Thanks. I have to get a nightly build going on that, will fix.
There will be another pass through the bugdb on this as well, against
the other proxy issues.

Re intended merge of this code with 1.3.x, note that -Wall compilation produces
an error in proxy_cache.c, in the function ap_proxy_cache_conditional. The
problem is that wetag is used without initialization in the case etag is NULL.
The if statement
836: else if (wetag && ap_proxy_liststr(c->inm, wetag, NULL)) {
should perhaps be changed to
836: else if (etag && wetag && ap_proxy_liststr(c->inm, wetag, NULL)) {
Another approach is to initialize wetag to NULL in its declaration
728: const char *etag, *wetag = NULL;
Yet another approach is to set it to NULL if etag is NULL
730: /* get etag */
731: if ((etag = ap_table_get(c->hdrs, "Etag"))) {
732: wetag = ap_pstrcat(r->pool, "W/", etag, NULL);
733: } else wetag = NULL;
If nothing is done, the results are unexpected. I.e., this is not a matter of
mere cosmetics, but a real bug. I regret I didn't send this in before, but
since it seems apache 1.3.x with the new proxy will actually be used before
2.0.x is in production, I think it should be clean.
Sincerely,
Zvi.
