I fully agree, the error is correct and deserved.
It is happening on both my 1.6 prod servers and my 1.8.8 test servers.
And I fully understand, and will do more to sanitize my inputs.
But the fact that warnings cause a seg fault / core fault of the whole
apache process makes my error reporting very difficult.
All I am asking is how / why does that error completely kill my execution
chain.
Perl test case example below:
#!/usr/bin/perl
use strict;
use warnings;
use Data::Dumper;
use SVN::Client;
sub SVN_CMS_BASE { return 'http://websvn.cc.domain.com/svn/www/cms' }
sub get_svn_ctx
{
return new SVN::Client(
auth => [
SVN::Client::get_ssl_server_trust_prompt_provider(\&_trust_callback),
# SVN::Client::get_ssl_server_trust_file_provider(),
SVN::Client::get_simple_provider(),
SVN::Client::get_simple_prompt_provider(\&simple_prompt, 2),
SVN::Client::get_username_provider()
]
) || warn "Unable to get connection...?!?";
}
sub simple_prompt
{
my $cred = shift;
my $realm = shift;
my $default_username = shift;
my $may_save = shift;
my $pool = shift;
$cred->username('svnuser');
$cred->password('svnpassword');
}
my $ctx = get_svn_ctx();
eval{
$ctx->ls(SVN_CMS_BASE . '/','HEAD',1);
};
if($@){
print "Error Occured!!! Let's report it\n";
die $@;
}
print "We survived!!\n";
