Bug description: Split hangs on something that 'file' does quickly
split hangs for some reason, but doing the same logical process with other
functions returns a very quick result.
The problem is that I'm trying to process the mysqlbinlog output and parse
it for easier management. The logical process is as follows.
$sys = `mysqlbinlog logfile`;
This part works fine, but when I try:
$lstk = split("\n", $sys);
the script hangs for well over 5 minutes (I kill the script at that time.
However this code produces the desired results in less than 2 seconds:
$mybin = "/usr/local/mysql/bin/mysqlbinlog";
$mylogpath = "/var/lib/mysql/";
$dolog = $mylogpath."towely-bin.010";
$tmpfname = tempnam ("/tmp", "mybinlogger");
$fp = fopen($fp, $tmpfname);
fwrite($fp, `$mybin $dolog`);
fclose($fp);
$lstk = file($tmpfname);
unset($tmpfname);
print count($lstk)."\n";
I am using this from the command line version of php 4.3.2 RC1. Here is my
php -v:
