Charles Mack commented on LOG4PHP-196:
--------------------------------------
I am unable to test this until tomorrow but I suspect that is because the file
is writing such a small amount and opens and closes quickly.
Try swapping:
{code}
for ($i = 0; $i < 100000; $i++) {
$logger->debug($i);
}
{code}
With this:
{code}
for ($i = 0; $i < 100000; $i++) {
$testString = $i . str_pad(" ", 10000, ' ')
$logger->debug($testString );
}
{code}
Also, the maxFileSize is set pretty small, meaning the file copying is quick.
Try 50MB over 100 kbs. The idea is to "trick" a process to keeping the file
that is being rolled open. Now that I that way, it does seem like a pretty
extreme use case but I would rather 10 50 mb files over several hundred 100kb
files.
This has been replicated on Windows 7 64-bit and Windows 2003 Server 32-bit. I
cannot attest for the current github version though.

> Project: Log4php
> Issue Type: Bug
> Components: Code
> Affects Versions: 2.2.1
> Environment: Windows
> Reporter: Kyle Wiering
> Labels: bug, fix, patch
> Fix For: 2.3.0
>
> Attachments: config_roll_windows.xml, fileroller.php, filewriter.php,
> LoggerAppenderRollingFileWindows.php,
> LoggerAppenderRollingFileWindowsTest.php, LoggerAutoloader.php
>
> Original Estimate: 24h
> Remaining Estimate: 24h
>
> Attaching a class extension to LoggerAppenderRollingFile named
> LoggerAppenderRollingFileWindows. This class enacts 'blocking' to keep
> seperate PHP processes from truncating the log file by attempting to roll the
> logs at/near the same exact time. It also uses a 'rename' in a manner that
> is much quicker then a copy for large files.
