[PHP-DEV] Small change in Apache2

[Teodor Cimpoesu]

Hi,
Apache 2.0.32 changed the prototype of ap_get_brigade.
To make php4.1.2 compile w/ it I had to do:

it's not an error message in Hebrew:
http://lxr.php.net/search?string=T_PAAMAYIM_NEKUDOTAYIM
http://www.google.com/search?q=T_PAAMAYIM_NEKUDOTAYIM

It's because of &variable construct, when the `$' in front of variable is left
out. 
I had fun when I first found it too :)

I don't think it's from getttext but from ssl.
It looks like Apache cannot find the SSL cert of the server. 
Also, are you sure /usr/sbin/apxs is the apxs of your running Apache ? (by the
location it appears to be installed from rpm).

I don't think it's a problem for a user to make a copy of the php binary
somewhere in any of those dirs, where the cwd at runtime is a writeable dir...

Can you tell more on what that patch is about and it's availability?

I guess it gets entropy from /dev/[u]random, but when it is exhausted it
cannot do much but to wait for more entropy.

Do you have /dev/urandom on that machine? I think urandom stands for
unblocking random (it returns w/o blocking if no entropy is available.)
There are also userspace programs that can gather entropy.

[wild guess]
probably the memory deallocation is the one expensive here.

BTW, don't use large arrays in PHP as Apache module cause when the process
grows requesting more memory (brk(2)) it cannot release it back to the
system (because the httpd process is still running).

[PHP-DEV] Apache2 debugging

[Teodor Cimpoesu]

Hi,
the README sais to set an environ var (or least I undestood so) in order
to debug it, but actually you have to define it (using -D on command line)
for it to work.

The change would be:

--- sapi/apache2filter/README.orig  Tue Nov 20 13:39:56 2001
+++ sapi/apache2filter/README   Tue Nov 20 13:40:35 2001
@@ -48,8 +48,7 @@

 1. Use the Prefork MPM (Apache 1.3-like process model) by
configuring Apache with '--with-mpm=prefork'.
-2. Set the variable "ONE_PROCESS" to 1 and export it before
-   starting Apache/a debugger.
+2. Start httpd with -DONE_PROCESS.

 If you want to debug a part of the PHP startup procedure, set a
 breakpoint on 'load_module'. Step through it until apr_dso_load() is

I saw it thousand times... ppl just miss that 
"'a string' is 0 when compared to integers".

try this instead: 
foreach (range(ord('A'),ord('Z')) as $i) echo chr($i);

Re: [PHP-DEV] popen() on Win32

I remembered I wanted to suggest you to take a look on how it is
implemented in
Python. Their docs state: """
popen (command[, mode[, bufsize]]) 

Changed in version 2.0: This function worked unreliably under Windows in
earlier versions of Python. This was due to the use of the _popen()
function from the libraries provided with Windows. Newer versions of
Python do not use the broken implementation from the Windows libraries. 


Python also has popen{2,3,4}(), [ in module os, also there is a popen2
module ].

I took a peek into posixmodule.c (iirc) but didn't figure out from
_PyPopen() how they
do it cause it's a bit over my knowledge :)

One can grab the python2.0 sources and have a look if interested (I
don't have the relevant file at hand).
