Re: no_cache pragma/cache-control headers : confusion
Hello, KOFrom the code in Apache.xs, it seems like setting $r-no_cache(0) will KOunset the flag, but not remove the headers. Well, the Expires header is also removed. But it's still broken; you can verify this buggy behavior with this simple script: use Apache (); my $r = Apache-request; $r-no_cache(1); $r-no_cache(0); $r-send_http_header; With mod_perls 1.24_01 and 1.25 on Apaches 1.3.14 and 1.3.19, this call leaves me with Pragma and Cache-Control headers. Sadly, the nice (but broken as per above) no_cache() behavior of sending those two headers is also undocumented in the mod_perl guide to begin with.

Re: Getting AuthCookie to return a wml page
Delivering text/html to a wap browser will definitely make it choke a bit :-) If you are using the same access mechanism for both web wap access then you have to sniff the client details to work out what to send back. Now you *could* look at the USER_AGENT string of the request and work off of that, but frankly that can get to be a real chore given the increasing diversity of wap browsers. (Yeah, you could match 'Nokia', 'UP' or 'Ericsson' to get most of them) Alternatively, best to look at the Accept content type field in the request, and match on text/vnd.wap.wml for the WAP users. For them, you'll then need to set the header type of any response to be that mime type. I'd have thought $r-content_type() should work, surely. You aren't using header_out() somewhere instead are you (IIRC the Eagle book says used content_type over this) ps: I find the Phone.com UP SDK more informative when dealing with errors in development. Of course, all the real phones deviate from the emulators anyway, but thats another story. pps: out of curiosity, are you relying on the wap gateway to store the cookie on behalf of the wap browser or what ? I was under the impression that not all wap browsers could deal with cookies Tim Fulcher Michael Smith wrote: Dear All, I'm trying to use AuthCookie to return a wml page for those lucky people on wap browsers. I've got it all working nicely for normal web browsers, but am getting errors on wap (and the Nokia Wap Toolkit doesn't tell me very much about why it's an error). One thing that looks a bit suspicious is the Content-type line which comes our as text/html - in fact to be precise it comes out as: Content-Type: text/html; charset=iso-8859-1 I've tried to override this with things like $r-content_type but to no avail. It seems that there's a line in http_protocol.c (line 2667) which is setting this (this response is harcoded there). Surely I ought to be able to override this ... in which case the obvious question is, how?

Re: PerlAccessHandler causes '500 Server Error' on 'return OK'
Hi. Sometimes, one has to answer one's own questions On Fri, Mar 30, 2001 at 03:00:08PM +0200, Jochen Schnapka wrote: Hi. I'm trying some of the well-known Apache-Perl-Modules, such as DayLimit.pm. Strangely, the server throws an internal error (500), when the Perl module returns 'OK'. The same is with 'DECLINED'.

The problem seems to be specific to the PerlAccessHandler Other Handlers (e.g.the PerlAuthenHandler) work fine: when returning OK, the page is displayed.

This statement has nothing to do at this place and should be taken out. See the apache docu for using 'Satisfy'.

I am currently developing a Perl based apache module and was

that the url that gets logged to the access.log is different
from what the client actually requested?
For example, if a client requested /file which was redirected
to this module could it modify either the request object or
some apache internal so that it gets written in the access log
as /file?session=1234567890abcdef .
I apologize if this is readily available from some FAQ as i
have been unable to find this information. Thanks for your
time.
This is untested, but I believe that mod_log_config logs, as part
of the %r CustomLog directive, r-the_request, which is the first
line of the request (i.e., "GET /file HTTP/1.0"). It might be
possible to do something like:
my @request = split / /, $r-the_request;
$request[1] = sprintf "%s?session=%s", $request[1], $r-param('session');
$r-the_request(join ' ', @request);
assuming that $r-the_request is not read-only.
Another option is to use CustomLog to log something other than
%r, like %{session}e to log an environment variable, or %q to log
the query string:
CustomLog "%h %l %u %t \"%m %U%q %H\" %s %b"
%m is the method, %U is the requested url, %q is the query
%string (or '' if no query string), %H is the request protocol.

system(), exec()?
Hi, I'm new to mod_perl, but I haven't been able to find an answer to this question. I'm used to mod_php4, and we use "safe_mode" to allow our developers to write applications, but restrict their access to files they don't own, and to stop them from using system() or exec() type calls. Is there anything like this with mod_perl? I'd like to offer them the ability to develop with Perl, but I don't really want to give them access to system() or exec() calls, or the ability to include files that they don't own. For instance, I don't want them to be able to pop up an xterm display from our restricted web server to their display. Any thoughts? Thanks, mga.

Optimizing memory use of modperl servlets
I've done extensive reading in both the guide and the maillist archives and haven't found a very comprehensive explanation of this topic. First I'll explain the setup of the scripts and webserver that we're using: I have 1 accessor script that the public would connect to "test.pl". Inside that script, I "use" a single module "test.pm" and then call "test::run()". When I just use this setup, and do no pre-loading, each servlet compiles the test.pm + all included modules on the first call and then it stays compiled for the duration of the servlet. This is ok, but the entire compiled network of included pm's caused the servlet sizes to be about 8 megs each. Fairly high if we wanted to run a lot of servlets on a minimal system. So I instead pre-loaded the test module in the startup.pl file during apache's loading session. This then seemed to save a lot of memory. With 4 servlets running, we went from aproximatly 30megs of total memory used to 20 megs. However, Once we started accessing the script and causing calls to be made to man aspects of the script, the total memory used spike to over 60megs! This seemed really strange since the memory used without library sharing was less!! Is this a problem with the way system-monitor (the way we were calculating the shared/real memory) reports stuff? Because each servlet was now reported to be ~15megs in size..about 7-8 megs bigger than before in the "non-optimized" state :) I understand that with shared libs, as global variables become dirty, pages become unshared. Is that true? Is it only for global variables? Or do local code pages become unshared when used? If so, then there would be minimal advantage to sharing libs on a very diversly active system since most code would become unshared quite quickly. Is there a technique to minimize the ammount of non-dynamic variables that get shared? Perhaps putting all dynamic variables into a seperate package and module? This interests me the most as a number of our variables are semi-large static data structures that may be contributing to the wastefulness of space when they lie on pages that are forced to be shared due to the global variable use. I suppose another possibility is optimizing those static data structures not to use too much memory. For example, a couple of those data strucutres are hashes. They are dynamically created at compile time and never change from that point onward so they should not causing a sharing issue. However, I don't know the internal representation of hashes in perl, though I can make some guesses. I assume it allocates a new chunk of memory every so often as variables are added. But I also assume it allocates more than needed to optimize for speed. Is there a way to 'prune' off that excess memory at some point? The advantage of doing that would be that if those variables do become unshared, their wasted memory doesn't get duplicated along side the data. I have one other question...entirly unrelated to the above problem...that is this. As i mentioned before, we have the 1 script, test.pl, that requires test.pm into it and calls test::run() to access the loaded libs. Is it possible to bypass this directly, and have all accesses to a particular virtual host "test.blah.com" instead of routing to test.pl (as it does now) be handled by the pre-loaded test.pm module (directly call test::run()) ? If anyone can help me on any of these issues, or point me to a page in 'the guide' or other web resource, I'd greatly appreciate it. - Bryce

Looking at your config, I would suspect the culprit to be use of DB_File on your StateDir, where /usr/local/etc/infosource/apps/netcfg/state-dir may be mounted over NFS. NFS typically does not support the flock() style locking that Apache::ASP uses to protect DB_File from corruption. If you are must use NFS, don't use DB_File, use the default SDBM_File, which does not corrupt as easily. If you need to get past the 1000 byte limit, then you might use MLDBM::Sync::SDBM_File which I developed just for this purpose. I need to add config support for this still to Apache::ASP though. If you can switch to a CIFS/or samba mounted file system, do this, as this supports flock() semantics. If StateDir is mounted locally, then possibly there is a bug in Apache::ASP StateDB locking, but this is less likely the case and we might look at other types of buffer overrun issues that might corrupt perl data structures. If your modperl httpd is compiled DSO, compile it static, as I have seen no end of odd errors with the DSO config from time to time. Also, DBD::Oracle and long values with CLOBs/BLOBs can create another type of buffer overrun, which is supposedly on OCI bug, though you didn't mention use of Oracle this is an odd bug that stung me recently. If you give up on trying to find this bug, which seems to be related to StateDB corruption, you may create $Application $Session objects with Apache::Session in the global.asa Script_OnStart, which would at least eliminate the StateDB issue. -- Josh _ Joshua Chamas Chamas Enterprises Inc.

Hangs / Out of memory
