[users@httpd] Apache 2.2.21 Seg Fault

Jeff, The cwmp handler has no functions like 'request_handler' and 'release_lock'.

Re: [users@httpd] Uncompressing incoming requests
Hi Nick,
I added some debug statements and error statements to mod_deflate code and
built the module.
The error is coming from the following
/* We didn't get the magic bytes. */
if (len != 10 ||
deflate_hdr[0] != deflate_magic[0] ||
deflate_hdr[1] != deflate_magic[1]) {
ap_log_rerror(APLOG_MARK, APLOG_ERR, 0, r, magic bytes don't
match); // --- I Added this error message
return APR_EGENERAL;
}
The client is using java.util's gzip to send a compressed message. Does that
mean that the gzip created from java.util library is not compatible with the
one that mod_deflate is using??
Thanks,
~Abhi

You should see quite a lot from mod_deflate if it's compressing
the output!
I can't say off the top of my head how much you'd see from it
doing nothing (as on your input), but at debug level I'd expect
it to tell you if it tries and fails to decompress something,
as opposed to (say) seeing content that's not labelled as
compressed and just getting out of the way.

[users@httpd] Uncompressing incoming requests
Hi All, I am trying to post compressed REST requests to apache. I have configured mod_deflate and have added the following configuration directive. Location / SetInputFilter DEFLATE /Location Even after doing the above configuration I do not see the requests getting uncompressed. Can any one help me with that. Thanks, ~Abhi
Re: [users@httpd] Uncompressing incoming requests
Hi Nick,
Yes the location scope applies. And the mod_deflate is loaded as well.
I have this directive defined in my conf file.
LoadModule deflate_module modules/mod_deflate.so
And to test it further I added the DEFLATE for outgoing content and I see that
the outgoing content is gzipped(confirmed this by snooping the outgoing packets
from the machine).
Location /
SetInputFilter DEFLATE
SetOutputFilter DEFLATE
/Location
I also added the following to log more details. I see that the outgoing
compression is logged. but do not see anything related to the incoming request
and its decompression.
DeflateFilterNote Input instream
DeflateFilterNote Output outstream
DeflateFilterNote Ratio ratio
LogFormat '%r %{outstream}n/%{instream}n (%{ratio}n%%)' deflate
CustomLog logs/deflate_log deflate
I added LogLevel debug to the httpd.conf file I do not see any extra logs in
the error_log file.
Should I do something further here to get detailed debug logs from mod_deflate?
Thanks,
~Abhi

You're sure the Location / scope applies?
What does the error log say if you set LogLevel Debug?
(oh, and - just checking - you do have mod_deflate loaded?)
p.s. Please fix your mailer to post text.

[users@httpd] Apache httpd with custom module does not start when I am not running is root
All, I have apache httpd 2.2.21. I load a custom module into it. When this is done I always need to be a root or sudo to start apache process. If I run apache as any other user the command 'httpd -k start' never returns to prompt. If I comment the LoadModule for my module apache starts fine even if I am not root. Any pointers why is this so. Am doing something wrong while building my module? I use apxs to compile the module. Appreciate your help!! Thanks, ~Abhi
