RE: non-DSO mod_perl, Embperl, and AIX not working
After making a few tweaks to the test.pl script and passing the 'h' command-line parameter (only do mod_perl tests) I was able to run all the tests (only under mod_perl) successfully. I then was able to run some successful tests against some .epl's that I had previously written using a different OS. I can't run Embperl outside of apache, but have only done that on the rare occasion anyway, so that's not a great loss. Thanks for all your help. It has been a few years since I have used AIX and was in much need of reminders related to AIX's "strange/different/odd/weird" linker. Again, thanks immensely for all your assistance. BTW, is it appropriate for me to offer to help with incorporating your knowledge into the Embperl install scripts? -- Greg Estep [EMAIL PROTECTED] -Original Message- From: Jens-Uwe Mager [mailto:[EMAIL PROTECTED]] Sent: Thursday, June 15, 2000 9:34 AM To: Greg Estep Cc: Jens-Uwe Mager; [EMAIL PROTECTED] Subject: Re: non-DSO mod_perl, Embperl, and AIX not working On Wed, Jun 14, 2000 at 07:11:11PM -0400, Greg Estep wrote: I then did an apache 'make install', even though I think that the Embperl compile and test processes use the source-code version of httpd...

RE: non-DSO mod_perl, Embperl, and AIX not working
Before I sent my original message, I tracked down all the symbols, and their object/library files. I added several ".o"'s and ".a"'s from the apache and mod_perl source trees, a couple from "/usr/lib/perl" and a couple from /usr/lib via '-lxxx'. After I got a clean link (there were some "duplicate symbol" errors) I had the same problem (seg. faults) as I had with the '-berok' flag. -Original Message- From: Shane Nay [mailto:[EMAIL PROTECTED]] Sent: Tuesday, June 13, 2000 8:22 PM To: Greg Estep Cc: [EMAIL PROTECTED] Subject: RE: non-DSO mod_perl, Embperl, and AIX not working Those are internal functions to apache, like helper functions. Your probably missing an object file in your ld command, I don't have it open right now, but just run nm blah.o|grep ap_palloc on all the object files running around in the apache directory, and you'll find it. (Notice that most of these functions "look" similar to C calls, that's because they sort of are. There like cross platform wrapper functions for apache, pretty cool huh?) Oh, yes and nm's output will tell you two things, where the function is "used", and where its "defined". BTW: I think you're looking for libap.a, I just poked through that archive of object files, and it contained the symbols you're looking for. I don't know if AIX supports linking in archive files, but if not just link in by hand all the object files in that directory. (apache_1.blah/src/ap/*.o) If nm shows the symbols in place, I would say it's probably the AIX linkers fault. I don't know much about AIX specifically but I have heard lots of people complain about their linker :-(. Thanks, Shane.

Both Apache and Perl are only doing the classic AIX style dynamic linking, so you cannot use the Linker Option -G to turn on runtime linking for a module, you must use the -bE:export file -bM:SRE options instead. The option -berok may not be used with the classic style dynamic linking, this is causing the segfault here. -- Jens-Uwe Mager HELIOS Software GmbH Steinriede 3 30827 Garbsen Germany Phone: +49 5131 709320 FAX:+49 5131 709325 Internet: [EMAIL PROTECTED]
RE: Embperl struggles
The LOG filehandle is predefined by Embperl. Anything written to it is put into Embperl's log file (usually /tmp/embperl.log). If you use a different name, you will probably be OK. On the other hand, you can just delete the call to "open" (and "close) and use the log file Embperl already provides. BTW, "LOG" and several other variables are discussed in the "Predefined variables" section of the HTML::Embperl man page. -- Greg Estep [EMAIL PROTECTED] #include std/disclaimer.h -Original Message- From: Toni Mueller [mailto:[EMAIL PROTECTED]] Sent: Friday, June 02, 2000 10:18 AM To: [EMAIL PROTECTED] Subject: Embperl struggles Hello, trying to develop with Embperl I encounter the following problems: 1.

non-DSO mod_perl, Embperl, and AIX not working
I am using IBM's C complier (cc) under AIX 4.3.3 with Apache 1.3.12, mod_perl 1.24 (statically linked, not DSO), perl 5.00503, and Embperl 1.3b3. The "offline", "execute function", and "cgi mode" Embperl tests are all successful. In the "mod_perl" mode, even the simple "ascii" test fails. It fails with a seg. fault and a dbx stack trace that looks like this: ap_palloc() at 0xd1179d98 EMBPERL__malloc() at 0xd1178b98 EMBPERL_SetupFileData() at 0xd1177118 EMBPERL_SetupRequest() at 0xd1177764 XS_HTML__Embperl_SetupRequest() at 0xd116fcb8 .() at 0x1004a344 .() at 0x100536f0 .() at 0x1002ff98 perl_call_handler(??, ??, ??) at 0x10113f70 perl_run_stacked_handlers(??, ??, ??) at 0x10113160 perl_handler(??) at 0x10111d38 ap_invoke_handler(0x2011f1f0) at 0x100c42bc process_request_internal(0x2011f1f0) at 0x100f4d6c ap_process_request(0x2011f1f0) at 0x100f648c child_main(0x0) at 0x10002d24 make_child(0x200498e0, 0x0, 0x39363aa3) at 0x100025a0 startup_children(0x2) at 0x1000248c standalone_main(0x4, 0x2ff228c8) at 0x10001928 main(0x4, 0x2ff228c8) at 0x100014b0 To get Embperl.so to successfully build I added "-b erok" to LDDLFLAGS.

RE: Problem with mod_perl
On Fri, 26 May 2000, Eugene S. Panenko wrote: Hi all, Sorry if it is an incorrect list to ask... I have a strange problem with mod_perl. I've tested mod_perl using a very simple scripts (one of them is attached). The network load is emulated via LAN using a special proggy. The problem is: under load above 20 requests per second after working some time (about 15-30 sec) Apache daemon stopts accepting new connections and blocks forever (without -X option httpd at this moment begin forking until it eats all resources) . I've found that the problem exists only when scripts use modules (tested with CGI v 2.46, IPC::Shareable, our own modules). Test scripts without modules work fine even under load of 200 requests per second. Without knowing too much about your apache config. files, machine specs, etc. I am guessing that your Apache MaxClients is still set at 150 (the out-of-the-box value). When apache receives a request that it cannot immediately handle (all of the pre-forked process are busy) it will fork another one (up to MaxClients). Eventually, you will run out of physical memory and begin to hit your swap space. When this happens, it takes longer to handle a request. That causes more requests to back up in the queue, so apache forks some more processes to handle the load. These new processes increase the amount of swapping that needs to be done, and the situation gets out of control. How many subprocesses you can support depends upon the size of your httpd process's text and data segments. I have seen several mod_perl applications increase the size of an httpd process to over 10 Mbytes. If you set MaxClients to a number that can be safely stored in physical memory (adjusting for the OS and other processes running on the machine, of course) you might eliminate your problem. -- Greg Estep [EMAIL PROTECTED]
