Re: [mp2] ModPerl::Test::read_post destructive?
Hi there, On Sun, 10 Aug 2003, Michael Maciag wrote: Is the read_post in ModPerl::Test destructive in some way? If so, could someone point me in the right direction I might take to modify it to be non-destructive? I think you'll find that reading POST data has always been destructive. If you want to read it more than once you have to save it somewhere. Check the archives for more information. 73, Ged.

mp1 rflush() and buffer size
I have a question concerning the proper behavior of rflush() with mp1. I'm
using Apache/1.3.28 and mod_perl/1.28 on OSX jaguar 10.2.6. Overall mp1
appears to work great. However, the following code does not work as
expected:
use CGI ();
my $r = shift;
my $q = new CGI;
print $q-header('text/html');
print $q-start_html;
print $q-p(Searching...Please wait);
$r-rflush;
# imitate a lengthy operation
for (1..3) {
sleep 1;
}
print $q-p(Done!);
The Searching...Please wait text does not display until the sleeps are
done. Adding $|=1; up top does not help. However, this code does work:
use CGI ();
my $r = shift;
my $q = new CGI;
print $q-header('text/html');
print $q-start_html;
for (1..263)
{
print $q-p(Searching...Please wait);
}
$r-rflush;
# imitate a lengthy operation
for (1..3) {
sleep 1;
}
print $q-p(Done!);
It appears that if I print out over 8k, the buffers flush. Less than that,
no flush. Is this proper behavior? And, if so, is there a parameter I can
change somewhere to lower the value or force a flush regardless of what's in
the buffer? I have tried very hard to find documentation or previous
discussion in this group to no avail.

[MP1.28 + perl maint. 20512] Build failure due to error in Apache/ExtUtils.pm
I tried to compile mod_perl-1.28 with perl maint.
20512 (http://www.iki.fi/jhi/[EMAIL PROTECTED]). I had a
build failure (different errors each time trying to
build).
I noticed the following messages during perl
Makefile.PL:

Digging through, the following in Apache/ExtUtils.pm
seem to be the problem:
sub Config_pm_fixup {
local $_ = $Config::Config{$key};
$sub-();
..
I could reproduce this using a small script:
$ cat repeat.pl
my $max_count = $ARGV[0] || 100;
while ($count++ = $max_count)
{
$ret = system(./oops.pl);
if ($ret)
{
warn #$count: Errored\n; STDIN;
}
}
$ cat oops.pl
#!perl
test('data');
sub test { replace() for (@_); }
sub replace
{
my %hash = (
ld = sub { s/(.*)/T1/e },
ccdlflags = sub { s/(.*)/T2/; },
);
while (my($key, $sub) = each %hash)
{
local $_ = 'test';
$sub-();
}
}
---
I ran it as:
$ perl ~/repeat.pl

1) The script ran perfectly fine on 5.6.1, 5.8.0 and
also on 5.8.1 RC4
2) This looks similar to bug # 23238
(http://www.xray.mpe.mpg.de/mailing-lists/perl5-porters/2003-08/msg00518.html)
3) local *_ before the local $_ in Apache/ExtUtils.pm
(or in the test script) solves the problem.
For whatever is worth, this is the above diff:

Now since this was working until RC4, I'd consider
this a bug. Should this go over to perl5-porters ?

Re: [mp2] Child process exited
Is it only mp2 that it fails under? I've tried it under mp1.28/perl5.8.0/apache1.3.27 on WinXP and it runs fine. I haven't tried other mod_perl versions, since the threading issue would render the site unusable. What version of Template-Toolkit do you have? It's worth ensuring that you're running the latest version (2.10, I think) if you suspect that it might be involved in the problem. Yep, I have 2.10. Nevertheless, thanks a lot for trying it. :-) J-S
