The reason the docs don't suggest that is that this is a new feature in apache 2.2 and as such has not been used by most people who contribute to the docs. Please try it, and if it works for you we'll update the docs. The graceful restart, which has been there for years, doesn't work well with mod_perl because it doesn't actually create a new perl interpreter, so all the old state is still there. - Perrin

apreq issues - test fail + no uploads
I'm having an issue with libapreq2 on my dev machine. I haven't used it in a while, so I reinstalled to make sure that I'm on the latest. First off, on the reinstall of libapreq2, I'm getting an error on make test: ( osx 10.4.9 ) perl -MTest::Harness -e 'runtests(@ARGV)' version.t cookie.t params.t parsers.t error.t util.t versionok cookie.ok params.ok parsersok 3/542 skipped: skipping ELF-dependent tests (parsers.c:134) error..ok util...FAILED tests 36-37 Failed 2/89 tests, 97.75% okay Failed Test Stat Wstat Total Fail Failed List of Failed --- util.t892 2.25% 36-37 3 subtests skipped.

I installed anyways, though I have a feeling these may have to do with my issue. Now, getting back to my code: my handler has this line: $apr= Apache2::Request->new( $r , POST_MAX=> 1_000_000 ); as a side note , it will die on this line; $apr= Apache2::Request->new( $r , POST_MAX=> 1_000_000 , DISABLE_UPLOADS=> 0); [Thu Apr 12 19:02:45 2007] [notice] child pid 12021 exit signal Bus error (10) note the DISABLE_UPLOADS=> 0 -- always gives me the Bus error. however, these lines always work: $apr= Apache2::Request->new( $r , POST_MAX=> 1_000_000 , DISABLE_UPLOADS=> 1); $apr= Apache2::Request->new( $r , POST_MAX=> 10_000 , DISABLE_UPLOADS=> 1); If i try to upload a 'small' item, i'll get this: "ERROR Unknown error: 0" as my body_status or the process will hang or i'll get a segfault. If I try to uplad something too big, i'll get the right 'too big' error, or the process will hang or i'll get a segfault -- mostly a segfault or hang. I'm rebuilding perl with debugging on this machine right now. and will post a stack trace later. pssibly in the mean time someone can point me in the right direction.
graceful stop?
I'm wondering if anyone uses Apache's graceful stop feature (http:// httpd.apache.org/docs/2.2/stopping.html#gracefulstop) with mod_perl servers. The mod_perl guide section on starting and stopping (http:// perl.apache.org/docs/general/control/ control.html#Safe_Code_Updates_on_a_Live_Production_Server) recommends using regular old stop. Doesn't this terminate any current user requests, with ugly results on the client? Wouldn't it make more sense to issue a graceful stop signal, setting GracefulShutdownTimeout to a low number (like 1) and then sleeping for at least that number of seconds? This would give current requests some time to finish, while avoiding the problems of running multiple identically configured instances of httpd at the same time. Thanks Jon

Charts and Graphs
Hello, I'm wondering what people are using for efficiently generating charts and graphs on the fly from within a mod_perl environment. I've been using GD::Graph for a while but I'm hoping to get a bit more feature-deep. I'm not terribly concerned about getting a bit more complicated if it means better efficiency and/or better control, etc. Any suggestions?
Re: 200 vhosts, 5 sets of libs, 2GB RAM, 1 httpd (seeking advice)
Thanks everyone for the suggestions. I appreciate it. Will ponder the options. Regards, Chris Hagglund.

I'd guess that he is, and that's why uses PerlOptions +Parent. See http://perl.apache.org/docs/2.0/user/config/config.html#C_Parent_ The problem with that strategy is that it means your 100 PROD vhosts don't share anything. The idea to set up the interpreter once for all the PROD vhosts is a good one, but I'm not aware of any context level in between vhost and global, so I don't think it will work. The proxy idea will work, and is not all that hard really. You could probably even rig the servers to all share the same config file and just have them choose which block to follow by passing -D options on the command line. - Perrin
