Apache::Filter/::RegistryFilter/::Compress problem.


folks --

  i'm wondering if anyone else has seen the following behaviour, and,
  if you have, how you dealt with it.  here's the problem:

  i have a bunch (200 or so) CGI scripts being handled by
  Apache::RegistryFilter then Apache::Compress, i.e., 

     <FilesMatch "\.(cgi|pl)$">
       SetHandler            perl-script
       PerlSetVar            Filter On
       PerlHandler           Apache::RegistryFilter Apache::Compress
     </FilesMatch>
  
  this typically works very well; however, on occasion i get the
  following error (reformatted):

      [Sun Oct 1 21:19:49 2000] [error] [Sun Oct 1 21:19:49 2000]
      null: Undefined subroutine &Apache::RegistryFilter::handler
      called at
      /usr/local/lib/perl5/site_perl/5.005/Apache/Compress.pm line 37.

  following this, any further registry requests made to this apache
  process result in this error.  here are some details:

    - it isn't the case that only one or two CGI scripts cause this
      error; there is no clear culprit.

    - MaxRequestsPerChild is set to 10.

    - the request that first causes this error takes a long time (300
      seconds or more) to complete.

    - this error only occurs on perhaps 3 requests in every 50k.

    - apache v1.3.9 on solaris 2.6
      modperl 1.21
      Apache::Filter 1.011
      Apache::Compress 1.002


  thanks for any suggestions, i appreciate your time.

cheers,
k.

      i don't; i've been letting mod_perl do its own thing there.
      i'll make that change.

      indeed.  it's pretty excellent how much of a performance kick
      compressing the content gets you.  furthermore, i like the
      apache::filter API (such as it is) -- it's been trivial to write 
      custom filters.

      thanks for your help.

      cheers,
      k.

Do you have StatINC in that mix anywhere?

Hi Kevin,

Do you also have config lines like

   PerlModule Apache::RegistryFilter
   PerlModule Apache::Compress

somewhere in the config file?  You should.  If you don't, I think
mod_perl does some magical loading of modules you need (I'm not even
sure of that, since I always load the modules explicitly), but it might
get messed up when new children are created or something.

Other than that, is the filtering setup working okay?
