So I'd suggest to upgrade to 5.6.1 if possible as the safest step, before 5.8.0 is released. All tested with Apache/1.3.25-dev (Unix) mod_perl/1.26_01-dev but the non-cvs version should probably work the same way. __ Stas BekmanJAm_pH -- Just Another mod_perl Hacker http://stason.org/ mod_perl Guide --- http://perl.apache.org mailto:[EMAIL PROTECTED] http://use.perl.org http://apacheweek.com http://modperlbook.org http://apache.org http://ticketmaster.com
bug: calling setlocale(LC_ALL,name of any locale with utf8 charset)more than once crashes httpd with mod_perl
Hi,
When using the following script under mod_perl, each httpd process crashes on
the 2nd request to execute this script.
#!/usr/bin/perl
use strict; use POSIX qw(locale_h);
setlocale(LC_ALL,'en_US.utf8');
print Expires: 1 Jan 1970\nContent-Type: text/html\n\nHi;
-
This crashes if instead of 'en_US.utf8' one uses any other utf8 locale that
is available in the system. If one uses locale with single-byte encoding (e.g.
'en_US.ascii' or 'ru_RU.koi8r') it doesn't crash httpd. (I didn't try
other multibyte encodings beside utf8).
If one uses LC_COLLATE instead of LC_ALL, it doesn't crash for any locale (I
didn't try other locale categories). (The httpd server is started under
locale 'ru_RU.koi8r' - a single-byte locale).
I'm using mod_perl on RH72 for x86, versions of the relevant software:
perl-5.6.0-17
mod_perl-1.24_01-3
glibc-2.2.4-19.3
apache-1.3.20-16
It seems it's a bug in mod_perl, since the following C program
--
#include locale.h
#include stdlib.h
int main(int argc,char** argv)
{
setlocale(LC_ALL,en_US.utf8);
printf(try 1\n);
setlocale(LC_ALL,en_US.utf8);
printf(try 2\n);
setlocale(LC_ALL,en_US.utf8);
printf(try 3\n);
return 0;
}
Works without crashing.
Also, the following perl script:
#!/usr/bin/perl
use strict;
use POSIX qw(locale_h);
for(my $i=0;$i10; ++$i)
{
setlocale(LC_ALL,'en_US.utf8');
}
print done\n;
Works without crashing too.
Granted, LC_COLLATE it's enough for my scripts, so this bug is not fatal to
me.
Best regards,
-Vlad

In any case, you should send a backtrace of the coredump according to the SUPPORT file found in the mod_perl source distro. __ Stas BekmanJAm_pH -- Just Another mod_perl Hacker http://stason.org/ mod_perl Guide --- http://perl.apache.org mailto:[EMAIL PROTECTED] http://use.perl.org http://apacheweek.com http://modperlbook.org http://apache.org http://ticketmaster.com
