Also, I experienced the same problem with APD for PHP 5.2.0 (http://nl3.php.net/apd)

I don't know about previous versions of PHP, I haven't tried them as I don't have the binaries of those versions.

Please try the latest version from http://pecl4win.php.net/ext.php/php_xdebug.dll, this should be fixed.

I tried the last version from PECL4WIN for PHP 5.2, and memory usage still isn't shown:

TRACE START [2006-12-11 21:10:41]

I have tried compiling php 5.2 with --enable-memory-limit (still on windows), but that doesn't seem to make any difference, no memory usage there either.

Also, the timestamp on the top of the trace file is set to one hour earlier than my system time for some reason. (This is a new output file, I deleted the old ones before testing the latest PECL4WIN release).

My timezone settings in php.ini are correct btw:

[Date]
; Defines the default timezone used by the date functions
date.timezone = Europe/Amsterdam

The date/time is expected, the log files always show GMT/UTC. I'll need some more time to check out the memory stuff. I will do that when I get access to a windows machine again.

Ok, looking forward to the results.
If you need some feedback/debug reports from a Windows machine, just ask me and I'll see what I can do.

I tested with PHP 5.0.5 and the same problem exists:

cmd: php -e -d zend_extension_ts=D:\server\php\php-5.0.5\ext\php_xdebug.dll -d xdebug.auto_trace=1 -d xdebug.trace_output_dir="/tmp/trace" -d xdebug.show_mem_delta=1 -d xdebug.trace_format=0 -r "$tmp = ''; function editme() {global $tmp; $tmp.= 'hoi'; } for($i = 0; $i < 1024; $i++) { editme(); }"

output:

0.0008 0 +0 -> editme() Command line code:1

0.0021 0 +0 -> editme() Command line code:1
0.0022 0 +0 -> editme() Command line code:1
etc...

On a stock PHP 5.0.5 it is expected as well, as memory limit is not enabled by default there either.

For what it's worth, I made a feature change request at php.net ;-)

Your feature request has been implemented in PHP Cvs now, so please get the latest Xdebug from pecl4win.php.net (dated after now). Please let me know whether it works as I still don't have access to Windows.

Cool, I'll have a look at it and will let you know some time later today.

Looks like pecl4win hasn't compiled for a few days (16 December for the last time), I'm waiting for the next build.

I can tell you that this works (it didn't before, it would exit because of the fatal error saying call to undeclared function):

D:\server\php\php5.2-win32-200612201130>php -r "echo memory_get_usage();"
50832

(this is a snapshot from yesterday)

So far, so good. Still waiting on the next pecl4win build :-)

Any idea when these builds occur?

I managed to build it myself, but unfortunately the memory stuff still doesn't show up because the MEMORY_LIMIT define is not set in the windows build.

Ah, that was my mistake. The module at http://xdebug.org/link.php?url=xdebug200rc2-521-win should work for you (as long as you have the latest PHP snapshot)

WOOHOO!!!

I just downloaded the latest snap and your .dll and it WORKS!!

Thanks, man!

Btw, if you need some more Windows testing, feel free to contact me.

cmd: php -e -d zend_extension_ts=D:\server\php\php5.2-win32-200612251130\ext\php_xdebug.dll -d xdebug.auto_trace=1 -d xdebug.trace_output_dir="/tmp/trace" -d xdebug.show_mem_delta=1 -d xdebug.trace_format=0 -r "$tmp = ''; function editme() {global $tmp; $tmp.= 'hoi'; } for($i = 0; $i < 1024; $i++) { editme(); }"
