Re: hi,about souce reading

[Liu Wen]

thank you for your advice. perhaps this is really somewhat crazy...
Anyway I heard Apache's code is well written, and I have previous
programming experience under Unix environment ,though not much.So I
think it is worth doing so...

well, I am still not sure reading 2.0 beta or latest stable version.2.0
seems to include a lot of new and useful features, maybe it makes good
to read the code as the developer group is releasing the final ? 

btw,I use MSVC to open dsw file in source tarball ,but no project is
loaded, why?

Cheers
Liu

This might sound crazy, but I would start with the httpd-2.0/server/mpm/prefork
directory, and review the basic outline of how prefork works and runs.  Prefork
starts its life as one process that reviews the configuration, then forks like
crazy into tens to hundreds of copies that serve individual requests.

Since the raw network_io stuff is in a directory srclib/apr/network_io/unix/ 
it's pretty easy to read over the abstractions, and then look at exactly how 
they were implemented.  Better yet - if you want to understand BeOS, OS2,
Win32 or NetWare, just jump over to the appropriate parallel directory and
you can get a glimpse of the differences.

If you try using 1.3, you will fall into http_main.c, a monstrosity of code
that goes on for miles.  The Apache 2.0 mpm architecture neatly broke things
up into parts, and the prefork flavor is probably the simplest to understand.
