That might remove /dev/null then. On a quick look through the code I had the impression you can not easily get rid of the pid file. Agreed - setting to /dev/null under the current code also fails startup anyway with the following error: (20014)Internal error: Error retrieving pid file /dev/null Remove it before continuing if it is corrupted. I haven't looked into it any further than that, though. Yes, to both concerns, it definately needs special treatment with a strcmp() (as I had hinted in my original note). But there isn't a sane reason to honor /dev/null, whereas there's no reason you couldn't name a pidfile 'none' in the serverroot directory. That's why I thought it would make a good no-pid sentinel value. How about as a non-sane name? /dev might be /Devices on some arcane Unix-like system but isn't a valid filename anywhere I've ever seen. -- Tim Bannister – is...@jellybaby.net
mod_ratelimit design mistake
https://httpd.apache.org/docs/trunk/mod/mod_ratelimit.html Provides a filter named RATE_LIMIT to limit client bandwidth. The connection speed to be simulated is specified, in KiB/s compared with external mod_bw.so IMHO this is a design mistake * saying i have several virtual hosts * my line has a capacity of 512 KB/Sec * one of the virtual hosts starts to have high traffic and abuses my upstream * SetEnv rate-limit 256 limits each client to 256 KB/sec at it's own * two of them abuse my upstream completly __ http://bwmod.sourceforge.net http://mariusvw.com/tag/mod_bw/ would limit the one vhost to 256 KB/sec. meaning in the case of 3 connections each would get 85 KB/sec. and the half of my available bandwidth is for other vhosts there is another interesting implementation detail of mod_bw LargeFileLimit * 500 786432 would only limit the bandwidth of files larger than 500 KB what is perfect in many cases to prevent line-overload by large downloads while respond with full performance to normal website-requests to serve small requests as quick as possible and prevnbt run out of workers IfModule mod_bw.c BandWidthModule On ForceBandWidthModule On LargeFileLimit * 500 786432 /IfModule signature.asc Description: OpenPGP digital signature

But mod_ratelimit does what it says. It's not fair to say whoever wrote it should have instead scratched the itch described above.

Re: Regarding apache server debugging source code

But I could only debug httpd binary and others present in bin directory. What I want is what exactly happens when a php script is deployed in apache server How are different apache handler modules called. I want to debug them. Firstly, launching httpd with -X (no forking, no detaching) makes any debugging project much easier. Secondly, debuggers allow you to pre-load dynamically loaded shared object modules. Your other two alternatives, are to set a delayed breakpoint on a soon-to-be-loaded module, or finally you can simply set a breakpoint in the mainline code after the config file (and therefore, loadable modules) are processed.
