Problem setting POST_MAX

Hi,

when I try to set POST_MAX to a higher value I get

Conflicting information.

I've a mod_perl / Mason app with an own hander, starting with
(mod_perl2)

sub handler () :method {
my $class = shift;
my $r = shift;
my ($app, $return);

my $args = $ah->request_args( Apache2::Request->new($r),
POST_MAX => 200 <<20);
....
}

I've also tried to set it via read_limit() with the same result.
What's wrong ?

The best explanation I've found is Philip's:

http://www.mail-archive.com/apreq-dev@httpd.apache.org/msg00 716.html

Basically you can lower the limit, but not raise it above the default
or that which is specified by APREQ2_ReadLimit (scope is directory) in
the Apache config.

Hello Rolf,

I think your code below might have a slight bug, I think you need to have have the POST_MAX as a parameter to the 'new'.

e.g.

$ah->request_args( Apache2::Request->new( $r, POST_MAX => ( 200 << 20 ) ) );

Instead of the call below:

$ah->request_args( Apache2::Request->new($r), POST_MAX => 200 <<20);

Here is the link to the documentation:

http://httpd.apache.org/apreq/docs/libapreq2/group__apreq__x s__request.html#new

HTH,

Lee

yes, typo, however the result is the same :=20

Wed Sep 17 17:06:59 2008] [error] [client 127.0.0.1] Conflicting information

So, it really looks like I can only define a limit lower than 64M, but not=
=20
set it to a higher value.=20

According to the documentation you can specify the limit in the Apache
configuration, i.e.,

APREQ2_ReadLimit 100M

I have not had success setting this directive. Nor does this work:

$r->add_config(['APREQ2_ReadLimit 100M']);

in a PerlHeaderParserHandler. If you do have success, please let me
know ;)

----

The Apache2::Request constructor attributes POST_MAX, MAX_BODY, and
READ_LIMIT are all passed to the same libapreq2 method,
apache2_read_limit_set, which, as of version 2.08, has this logic:

if (ctx->read_limit > bytes && ctx->bytes_read < bytes) {
ctx->read_limit = bytes;
return APR_SUCCESS;
}
return APREQ_ERROR_MISMATCH;

Where bytes is the value you specified with POST_MAX and
APREQ_ERROR_MISMATCH is "Conflicting information".
