Hi Steve, I see now; that's something I struggled with too, until Doug pointed this out; try Alt+7 to give a stacktrace window (look under View -> Debug Windows). And perhaps also to save some grief, if you want to copy it, select+right-click within that window doesn't work; you have to select+Edit->Copy. -- best regards, randy

Your patch passes the current interpreter context to
modperl_hash_seed_init(), and thus the interpreter-wide variables. I
don't see problems with it, but I don't know anything about the mod_perl
2 internals.

When possible, try to use Perl_error_log instead of PerlIO_stderr().
It's equivalent to it, but checks for the availability of STDERR
beforehand. And BTW the trace below should probably be out#defined for
non-debug builds.

I still haven't found out what the problem with the server crashing on
startup is, but the attached patch against CVS seems to fix the
fprintf() problem that you refer to.

Re: [MP2] Strange slow MySQL queries
Hi, This looks more like a MySQL problem than a specific MP2 issue. However here are a couple of pointers. All the queries below are updates on the same table this would indicate to me you may be having a locking issue. What you need to do is locate the locking transaction it may be as simple as :- select * from innodb_tbl for update; This locks the whole table and would block all of the quiries highlighted. Hope it helps Paddy P.S. Please feel free to contact me off list if you wish to go into more depth. Are you using Apache::DBI or transactions?

Re: [mp2] executing subprocesses from mod_perl
Haroon Rafique wrote:
Hi listers,
Just needed a quick opinion:
http://perl.apache.org/docs/2.0/api/Apache/SubProcess.html
suggests that Apache::SubProcess be used for executing subprocesses.
Howerver, in an earlier list message,
http://marc.theaimsgroup.com/?l=apache-modperl&m=102541721726752&w=2
Stas had suggested that either IPC::Run or Apache::SubProcess could be
used.
I have 2 versions of a mod_perl script using either of the modules. Which
one would be preferred and why?
Some reasons come to mind right away, e.g.,
* IPC::Run may be more mature (version 0.75), so use it.
Don't forget that Apache::SubProcess is just a glue for the C library, which
is quite mature as well. This C library works on all platforms Apache works.
I'm not sure about IPC::Run. Spawning processes on different OSes is quite
different.
* IPC::Run is a separate install, so don't use it.
* Apache::SubProcess is distributed with mod_perl, so use it.
etc...
IPC::Run should be used instead of IPC::Open3, since the latter doesn't work
under mod_perl. You probably should be able to use any of the two (IPC::Run or
Apache::SubProcess). You could try to benchmark to see which one is faster.
Apache::SubProcess is written in C.
Apache::SubProcess has extra features (see appendix B in the "practical
mod_perl" book and should also be in the guide, but not all were ported yet).
e.g. in mod_perl 1's Apache::SubProcess, you can send the output of system()
to the client:
use Apache::SubProcess qw(system);
my $r = shift;
$r->send_http_header('text/plain');
system "/bin/echo hi there";
but this wasn't ported yet.
in 2.0 you can set subprocess env:
$r->subprocess_env->set(SubProcess => $value);
my $out_fh = Apache::SubProcess::spawn_proc_prog($r, $perl, [$script]);
my $output = read_data($out_fh);
Also you may want to use Apache::SubProcess to stress it out and see if there
is something that we need to fix, if it's not used we might not be aware of
existings bugs that the tests don't catch. You can always switch to IPC::Run
if you encounter some problems.

So instead of advertising the workaround, I'd rather see it fixed. However if the general opinion is that we want to make the workaround more visible, we can do that as well.

Not at all, Steve didn't see it on Windows with *another* version of mod_perl... I'm using 1.99_10, he was using 1.28. So if you can test under Linux with 1.99_10, it might have the same problem.

Re: [mp2] Child process exited
I can't help you with those things without being able to reproduce the problem :(
but see below regarding the reload confusion.
[...]
# Add the top-level directory for the modules into the module search
path.
use lib qw($ENV{SCRIPT_ROOT});
Apache::Reload didn't seem to want to reload my modules.
because it probably couldn't find them.
I had followed the instructions you stated before, and you can even see
my "use libs" in the startup.pl I included above. Let's say
$ENV{SCRIPT_ROOT} (as set in my httpd.conf with a PerlSetEnv) is set to
"d:/htdocs", that means that a module being use()d as Hybride::Blah
would be found at d:/htdocs/Hybride/Blah.pm right? So Apache::Reload
should find it at the same place, since the "use libs" is in the startup
script.
But Apache::Reload still does not reload my modules... And as I said,
"ReloadDebug On" didn't even tell me if it was trying to reload them.
Nothing in my error_log, same as with the warnings.
No, that won't work, unless you set SCRIPT_ROOT env var in your shell.
PerlSetEnv has an effect only during a request time. You want it during the
startup time.
You can dump the value of @INC, so see that d:/htdocs is not there (at the
server startup).
One of the following will work.
PerlSwitches -Id:/htdocs
or
PerlSwitches -Mlib=d:/htdocs

Re: [mp2] Child process exited
It's possible that some of your code or the modules that you use
either misuse
$^W or trap $SIG{__WARN__} which prevents from warnings to be printed.
grep
for these two things.
Remember - there's only the code I showed you. No other modules (other
than Template, strict and warnings which are use()d in index.cgi) and no
other code than the index.cgi I sent you.
You did load things in startup.pl, remember? some module could override
$SIG{__WARN__}. Don't load those modules if you don't need them.
You could also try to reset it in your code:
perl -wle '$SIG{__WARN__} = sub {}; $SIG{__WARN__} = sub {CORE::warn(@_)};
warn "foo"'
foo at -e line 1.
but you need to do that in the BEGIN block, so it'll happen before the
compilation of the rest of the code is done:
BEGIN {
$SIG{__WARN__} = sub {CORE::warn(@_)};
}
use strict;
use warnings;
the rest of your code
In any case your problem with variables not staying shared (even though you
can't see it reported is easy to see).
http://perl.apache.org/docs/general/perl_reference/perl_reference.html#my___Scoped_Variable_in_Nested_Subroutines
You also don't want to initialize $template on every request, see the Template
docs/list archive to how make it more efficient (which will also remove the
my() problem).
make $vars and $config global as one of the workarounds.
So if on your side there are warnings and not on my side, with the same
code, then that's a problem too...
Yes, especially since you have a scoped warnings enabled explicitly in your
file. Does you perl print this warnings when you run a test script from the
above URL?
Now that I think of it, when I started testing mod_perl (back when my
code was not correct and I was fixing errors to make it work), I
remember that Apache::Reload didn't seem to want to reload my modules.
Even with the ReloadDebug variable on, nothing was ever printed to my
error_log saying that my modules were reloaded... So the warnings issue
could be related to this too.
because it probably couldn't find them. See:
http://perl.apache.org/docs/2.0/api/Apache/Reload.html#Description

Re: [mp2] Child process exited
Stas, I just checked, and when the Apache crash occurs, nothing gets written to access_log. It would seem that the crash happens before the request is logged. Also, > b) why my warnings don't show up in the error_log. I just moved my mod_perl config from httpd.conf to another file, mod_perl.conf, and Include that in httpd.conf. (I did that so that I don't have to comment the whole section for mod_perl when I want to deactivate it, I just have to comment the Include line). Now, magically, the warnings and the Apache::Reload debug messages show up in my error_log! The only other thing I changed between now and before is that I added the "PerlSwitches -Id:/htdocs" directive.

I very much doubt anything in my startup.pl would modify the signal
handlers. Here's my startup.pl, for reference:
use strict;
use warnings;

use Apache2 ();

No. I just tried it. It does show the erroneous response (5^2 = 25 6^2 =
25) but no warnings. I also tried with the code to restore
SIG{__WARN__}, and it didn't change anything.

OK, I've now got Apache 2 building (with a little off-list help from
Randy Kobes - the secret is to use the .zip sources rather than the
.tar.gz sources!), and I've built mod_perl 1.99_09 (not 1.99_10-dev as

The bads news is that I haven't solved it, but I'll keep trying and let
you know if/when I do.
I don't any Application Error popup window, but my NS7.1 browser says
"The document contained no data", while IE6.0 gives the usual useless
"The page cannot be displayed" crap that it always does.
I also get nothing in the access.log.
The error.log contained this:
Variable "$template" will not stay shared at
C:/apache2/perl-bin/index.cgi line 26.
Variable "$vars" will not stay shared at C:/apache2/perl-bin/index.cgi
line 26.
[Thu Aug 14 10:37:04 2003] [notice] Parent: child process exited with
status 128 -- Restarting.
The "variable will not stay shared" error is a common problem with
mod_perl scripts that have file-scope lexical variables in them which
subroutines access. My usual solution is to put the main part of the
program into a block labelled "MAIN:". That way they can't be "shared"
to start with, and I have to explicitly pass them into any subroutines
that require them. The attached new version of your "index.cgi" does
this, and makes these errors go away. I now have just this in the
error.log:
[Thu Aug 14 10:41:42 2003] [notice] Parent: child process exited with
status 128 -- Restarting.
The index.cgi program runs fine in a command prompt (with SCRIPT_ROOT
set in the environment), so its not an obvious TT error.

Thanks for trying out my code.
Jean-Sebastien, are you *sure* that what crashes is apache and not
your
client? it seems that you have the client crashing if removing
changes
everything. What's your error_log says?
My client is IE, and it stays open and responsive after the crash
message. The crash message itself is a dialog box titled "Apache.exe -
Application Error"... That's pretty much a dead giveaway that it isn't
my client that's crashing.
My error_log says:
[Tue Aug 05 11:10:58 2003] [notice] Parent: child process exited
with status 3221225725 -- Restarting.
[Tue Aug 05 11:11:00 2003] [notice] Parent: Created child process
1360
so I'm pretty sure it's either Apache or the Perl instance started by
Apache that's crashing. What's more, from the command line and from
normal CGI, the same script (with identical output) runs without any
crash - client or otherwise.
Good, just a sanity check. it sounds silly that changing an html will break
the server, but anything could happen. Is it possible that the broken(?) html
makes IE do silly things, that cause the server crash in the afteraction? e.g.
I'd check the access_log to see whether it issues only one request or more.
Also make sure to debug in the single process (thread?) mode (httpd -X)
BTW, I can't reproduce you problem.
That's bad news. Of course, this may be platform-specific... Did you try
on Win32?
I don't have win32.
Where should I go from here? This is really preventing me from using
mod_perl at all. As I said, the same things run without problems in
normal CGI.
I'm not a win32 person, so I'm not quite sure how you debug things there. But
what you need to do is to get the server dump the core file, which will tell
us where exactly it crushes.
Hopefully Randy will come back from vacation soon and will help you out. Or
may be someone else.
You must run your code with warnings
enabled, add to httpd.conf:
PerlSwitches -wT
and you will see:
Variable "$template" will not stay shared at /tmp/CRUSH/index.cgi line
26.
Variable "$vars" will not stay shared at /tmp/CRUSH/index.cgi line 26.
which is probably unrelated to your problem, but it's very bad. Search
perl.apache.org for hints how to resolve the latter.
Thanks for the hint. I just modified my httpd.conf to include the
PerlSwitches line, and I don't get the same warning messages you do...
(actually I don't get any warning message) Is there a reason for this?
It's possible that some of your code or the modules that you use either misuse
$^W or trap $SIG{__WARN__} which prevents from warnings to be printed. grep
for these two things.
whenever you override $^W, this must be done with:
local $^W = $whatever;
so it won't affect other code. same with $SIG{__WARN__} if possible.
I'd suggest that you first get these warnings working and reported, then you
fix your code to avoid these warnings (with the non-crashing version of the
template), then move to solve the original problem.

Should I send the zip to the list or to your private address? I'll also include the short setup instructions. Most likely someone on win32 will have to try it.

Re: [mp2] Child process exited
> I've actually pinpointed the problem to one HTML tag in the output that > Template-Toolkit sends to Apache as a result of the cgi script's run. Actually, I've just found out another thing, which is really weird. If I just change the amount of whitespace in the template file (see the zip file linked in my last post), I can make Apache crash or not. Open up the template file, remove the and tags, and refresh the browser. It should display the page with the header. Go back to the template file, place the cursor right after the tag (on the same line), and press enter 3 times. There should be 3 blank lines between the title tags and the tag. Refresh the browser. In my case, it crashes. Also, 1 or 2 empty lines doesn't crash, but 3 or more does. I'm beginning to think there must be something very wrong with my own code. I'm almost sure it isn't something with Apache or TT. I must just not be seeing it.

Steve,
and the good news for you is that I've reproduced your problem.
GREAT! Thank you so much for persevering through this! So do you have a
traceback or some info that the developers might be able to use to track
this down?
Not sure how to get a stack backtrace on Windows. I don't even get the
Application Error popup window with a "Debug" button inviting me to have
go :-(
However, I have massively simplified the test program that reproduces
the problem.
I've moved the template itself in-core rather than processing an
external file and removed everything else that I could without the
problem going away. I found that almost whatever I removed from the
template -- not just the tag -- "fixed" it, and I began to wonder
about the *size* of the template.
So then I replaced the HTML page content with loads of dots, and sure
enough, the problem goes away if you reduce the number of dots
sufficiently. It seems that the program breaks if the template size is
> 612 bytes, and works if it is <= 612 bytes! (Try changing $size from
613 to 612 in getTemplate() to "fix" it!)
Template-Toolkit's Template::Manual::Config manpage says that Perl will
segfault using the INTERPOLATE option with templates > 32 kB due to
limitations in Perl's regex engine, and sure enough another way to "fix"
the attached program is to change "INTERPOLATE => 1" to "INTERPOLATE => 0".
I don't know where the 612 byte limit comes from, but it's certainly not
Perl itself that has such a small limit -- the program runs fine in CGI
and mod_perl 1 environments with $size set way higher than 32 kB on my
machine.
So a temporary fix would appear to be to not use the INTERPOLATE option
if you can manage without it.
I might have to leave it to Randy for a fuller explanation of where the
612 bytes limit is creeping in.

Re: [mp2] Child process exited
Stas, Thanks for trying out my code. > Jean-Sebastien, are you *sure* that what crashes is apache and not your > client? it seems that you have the client crashing if removing changes > everything. What's your error_log says? My client is IE, and it stays open and responsive after the crash message. The crash message itself is a dialog box titled "Apache.exe - Application Error"... That's pretty much a dead giveaway that it isn't my client that's crashing. My error_log says: [Tue Aug 05 11:10:58 2003] [notice] Parent: child process exited with status 3221225725 -- Restarting. [Tue Aug 05 11:11:00 2003] [notice] Parent: Created child process 1360 so I'm pretty sure it's either Apache or the Perl instance started by Apache that's crashing.

Of course, this may be platform-specific... Did you try on Win32? Where should I go from here? This is really preventing me from using mod_perl at all.

That's what I was wondering too when I reported that just adding 3 line breaks somewhere in the file "broke" it, and removing them "fixed" it. I would never have thought that such a small template would break based on size, though, since I have much larger templates in production using normal CGI, which work fine. (the largest template is ~20k and the average is ~6k). Again, I'll have to remind myself to "never assume"... I kept on telling myself, "Nah, it can't be the size of the template file...".

Re: [mp2] Child process exited
So, has anyone checked out my test case? Any results (good or bad)? As I said in my last post, I'm getting this for differing amounts of whitespace in my template files, so it isn't just one tag to be removed everywhere. I have something like 30 template files, most of them much more complex than the one in the test case, so it would take a real long time to go through each one, trying to get them to work by trial and error.

Sorry for getting late to this thread, this is a bug in mod_deflate. You don't
see it in mod_cgi, because mod_cgi doesn't really handle buffering and
flushing, since it just reads the data from the pipe to the process.
mod_deflate didn't follow the deflate() spec, saying that the caller shouldn't
call deflate, when there is no data to deflate. Try this patch:

Please read the README before trying to run it. In it, you'll find details on my config and a short discussion of what happens in the various cases I tried. Note that since I found the tags that cause the problem, I can continue to work without them, but I'd still like to know why it crashes on a script that ran perfectly in straight CGI.

I like to put use() statements for all required modules in each module that needs them. It's good documentation. When you tune your system for performance, you will put all of these in startup.pl to improve shared memory, but there's no need to take them out of the other modules: use() staments for modules that have already been loaded simply skip the require() part and run the import(). - Perrin

Re: [MP2] Placing Apache::RequestRec & Apache::RequestIO & APR::Tableuse statements in startup.pl
It will work. Just be careful - if you distribute this module, the people who use it may not include these modules in their startup.pl, and if you discontinue usage of this module, you may end up with extra modules in memory which aren't needed.

Re: [mp2] BEGIN blocks
I'm not really sure what's going on...
I tried making a test module to see what was going on inside, which appeared
to function correctly. However, the "real" module is still having troubles.
The database handle is opened ($dbh=DBI->connect...) in a BEGIN block in the
"real" module, but the connections don't seem to work when the server
originally loads, until I make a change in the file and Apache::Reload
reloads it (after which it works fine as long as the server's alive).
Here's the module and test results :

My mistake, its been a while and I'm just getting back into it. So its
like I'm learning everything all over again. You can use OK? The example
in the Eagle book uses REDIRECT within a handler for redirection. So I'm
assuming it goes the same for MP2.
You are right, one returns OK if using parsed headers, as in this example:
sub handler {
my $r = shift;
my $location = $r->args;
print "Location: $location\n\n";
Apache::OK;
}
I got the redirection to work. However I don't think its working as it
should. Nowhere in the docs does it say that you have to load APR::Table
with Apache::RequestRec and Apache::RequestIO to have $r->headers_out()
to work. Without APR::Table loaded I get the error:

$r->headers_out returns a tied hash reference, so ones needs to load
APR::Table in order to work with this reference. Doc patches are very welcome.

I got the redirection to work. However I don't think its working as it

Place APR::Table in and the error goes away. Here's a sample script

This is another story! You have a problem with ModPerl::RegistryBB. HTTP log can't help if ModPerl::RegistryBB aborts at that point. From my point of view it is supposed to be a warning (or debug/warning) instead of the error in ModPerl::RegistryBB, because it could be necessary sometimes to flush empty string (for example, to overwrite the default chunking behavior of core Apache). Unfortunately, I can't look into the sources of Apache-2 now. Can somebody help to patch this problem on Bill's machine first in order to let us to go ahead with this research? Thanks, Slava
Re: [mp2 Patch] BUG with mod_deflate and $|=1 (20014:Error string not specified)
We can see that mod_cgi bufferizes the output and sends it with Content-Length HTTP header (to mod_deflate). Indeed mod_perl generates chunked response. Finally we have the same result. I don't see any problem at this moment. Well, the problem is that I get this error in my error_log: [Mon Jul 21 14:18:55 2003] [error] 4297: ModPerl::RegistryBB: 20014:Error string not specified yet at /var/www/perl/test.pl line 6. Also, more important, the script seems to be terminating and/or any output following the 'print ""' is not sent to the client as far as I can tell. You would probably wish to append your script with additional output after the empty string? Something like: #!/usr/bin/perl $|=1; print "Content-Type: text/html\n\n"; print "hello world"; # This line causes the error (?) print ""; print "hello again"; --- When I do this, the mod_perl variant of the script fails to print "hello again". mod_cgi prints everything just fine and gets no errors. I changed my test script to print a bunch of `date`'s http://shevek.kenyonhill.com/cgi/test.pl http://shevek.kenyonhill.com/perl/test.pl It may cause a problem for chunked output if mod_deflate does not care to keep internal buffer and check its size when flushing... I may not be understanding the output you sent or what you're saying, but I still don't follow why this would be a mod_deflate bug if mod_cgi with the same script has no problem.

Re: [mp2 Patch] BUG with mod_deflate and $|=1 (20014:Error string not specified)
I can measure it myself if you can provide me with URLs to your resources and identify them in terms of which one is mod_CGI and which is mod_perl. This is the mod_cgi one that works fine, no errors: http://shevek.kenyonhill.com/cgi/test.pl This is the mod_perl one (same script) that generates the "20014:Error" in the error_log. Also, the page doesn't display correctly (it seems to erase itself): http://shevek.kenyonhill.com/perl/test.pl This is the contents of test.pl: --- #!/usr/bin/perl $|=1; print "Content-Type: text/html\n\n"; print "hello world"; # This line causes the error print ""; --- Let me know if you need anything more.

Re: MP2 variables
[redirecting to the modperl list, as others will want to know the answer as well] Hi Jamie, What is the MP2 equivalent of $Apache::ServerStarting? I'm trying to get Apache::DBI working with MP2. % grep Server::Starting todo/* todo/deprecated_features.txt:- $Apache::Server::Starting, $Apache::Server::ReStarting In Apache 2.0 the configuration file is always parsed and executed, on start and restart, so everything is executed as many times as this happens. Moreover when you stop the server, it gets executed as well, which is a bummer IMHO. But that's how Apache 2.0 works. __ Stas BekmanJAm_pH --> Just Another mod_perl Hacker http://stason.org/ mod_perl Guide ---> http://perl.apache.org mailto:[EMAIL PROTECTED] http://use.perl.org http://apacheweek.com http://modperlbook.org http://apache.org http://ticketmaster.com

Re: [mp2 Patch] BUG with mod_deflate and $|=1 (20014:Error string not specified)
Hi guys, In my understanding _it is_ a problem of mod_deflate. It's a bit tricky to flush dynamically generated content over HTTP/1.1: Core Apache marks the end of your document with empty chunk. When you flush an empty string in the middle of your document Apache has no way to serve your directions, but to create an empty chunk immediately. The first empty chunk received by the client is recognized as the end of the document. The rest of the data stream is just ignored. I didn't have a chance to look into the source of mod_deflate yet, but this definitely has to be taken into account over there. In my understanding it would be the best our bet just to bring this issue to the attention of the author of mod_deflate. It's supposed to be easy to fix.

Re: [mp2 Patch] BUG with mod_deflate and $|=1 (20014:Error string not specified)
I could upgrade to 2.0.47, but it seems unlikely that it would fix
this. Are you sure you're running a mod_perl without Philippe's fix (in
Apache__RequestIO.h), I assumed he eventually checked it in.
No, Philippe hasn't committed it, neither I have used it. If you can test
with 2.9.47 that will help. Otherwise I'll later try with .46 as well.
I just upgraded to Apache 2.0.47 and the latest CVS of mp2 and I'm
reproducing it, same as I originally reported.
I tried a few variations to see if I could find other factors, but didn't
have much luck. The server I'm testing on is live (runs a small site), so
I'm somewhat limited in what I can do. But, I tried removing mod_rewrite,
and mod_ssl from my server config and I still got the error in my tests.
I also tried varying the mod_deflate config (as you pointed out it was
redundant/wrong)...
Also Bill, why do you have this setup:
AddOutputFilterByType DEFLATE text/*
SetOutputFilter DEFLATE
why adding it twice? You need only the latter inside , or
alternatively only the former outside if you want it to be
set globally:
http://httpd.apache.org/docs-2.0/mod/core.html#addoutputfilterbytype
Ah, I misunderstood the mod_deflate docs. I think at the time, it didn't
seem to work with just one of them in-place, so I added the
other. *SHRUG* I can't say I'm a pro at Apache config files, I just
tinker until it works. I assume this is irrelevant to the bug, though.
I'm not sure if your config doesn't insert the filter twice. Need to check
whether SetOutputFilter overrides AddOutputFilterByType as well.
In my config, I have a deflate log:
DeflateFilterNote Input instream
DeflateFilterNote Output outstream
DeflateFilterNote Ratio ratio
LogFormat '"%r" %{outstream}n/%{instream}n (%{ratio}n%%) "%{User-agent}i"'
deflate
CustomLog /var/log/httpd/deflate_log deflate
I was using this to verify that deflate was active or not. What I found
was that using "AddOutputFilterByType DEFLATE text/*" doesn't seem to
activate deflate, no matter where I put it (in a or at the
top-level of the config). My deflate log shows that no compression is
occurring. "SetOutputFilter DEFLATE" does activate deflate globally (for
all locations), no matter where I put it. I'm afraid I don't find the
mod_deflate docs very clear on placement.
When you were trying to reproduce, I don't know if you used my (redundant)
config before, but if you only used "AddOutputFilterByType DEFLATE text/*",
and not "SetOutputFilter DEFLATE", that might explain why you were not able
to reproduce this, I don't think that activates deflate (at least that's
what my deflate_log shows for me).
Otherwise, if you're still not reproducing this, I would assume there's
some difference in the way we are building apache or our apache config
files or perl?
Here's my Apache Configure line:
./configure --enable-modules=all --enable-mods-shared=all --enable-deflate
--with-mpm=prefork --enable-rewrite --enable-ssl
Here are the Modules I load:
LoadModule cgi_module modules/mod_cgi.so
LoadModule access_module modules/mod_access.so
LoadModule log_config_module modules/mod_log_config.so
LoadModule env_module modules/mod_env.so
LoadModule expires_module modules/mod_expires.so
LoadModule headers_module modules/mod_headers.so
LoadModule setenvif_module modules/mod_setenvif.so
LoadModule mime_module modules/mod_mime.so
LoadModule autoindex_module modules/mod_autoindex.so
LoadModule asis_module modules/mod_asis.so
LoadModule info_module modules/mod_info.so
LoadModule vhost_alias_module modules/mod_vhost_alias.so
LoadModule dir_module modules/mod_dir.so
LoadModule alias_module modules/mod_alias.so
LoadModule rewrite_module modules/mod_rewrite.so
LoadModule perl_module modules/mod_perl.so
LoadModule ssl_module modules/mod_ssl.so
mod_cgi, mod_ssl and mod_rewrite seem to be innocent (when I removed them,
it still failed), but maybe you're using a module that I'm not and this is
causing your config to work better? I think that I'm loading less modules
than what is typical, I removed as many as I could to reduce memory usage a
while ago.
*SHRUG*
One thing that may be relevant is tracking down where the "20014:Error" is
coming from. Web searching seems to associate it with Berkeley DB code,
which seems odd to me, is Apache using Berkeley DB code somewhere (via a
filter?)?
This isn't a very important issue for me. I have a decent workaround
(print " " instead of ""), plus I'm not really able to use mod_deflate that
much anyway because it puts too much load on my server (mod_gzip with
Apache 1.3 worked better for me).
Thanks
