Why do you want to take it away?
I think PerlRestartHandler is a better solution in most cases. and inside
Perl sections you can always do it on your own:
Perl
do_something() unless $My::Init++
/Perl
Sure
I'm cringing at global variables in general looking forwared to threaded
2.0. do you have a concrete example that requires
$Apache::Server::{Starting,ReStarting} ?
You can get away with internal tracking like you did above with $My::Init,
but IMHO it's not a clean approach. How about adding a new method that
will return the server status. No global variables needed.
do {} if Apache::server_status() == Apache::Constant::Starting;
So you can add other modes like,
Starting|Restarting|Running|HavingLunch|Stopping|Dyeing.
The examples are:
* Start/Restart - when some heavy startup operation should be performed
(e.g. a heavy XML parsing and preloading like someone posted awhile ago)
* Stopping - I wrote this runaway watchdog and had to make it a standalone
program which has no idea whether the server is running. I wanted the code
to be aware of the server status and spawn from the startup file, and kill
it when the server is stopping... I guess I can provide more cleanup
scenarios too.

Re: a possible bug with Apache::Server::ReStarting
Hi, While documenting the 'restart twice on start' apache's behavior, I've tested $Apache::Server::ReStarting and $Apache::Server::Starting. Perl section is executed twice -- OK. startup.pl is executed once -- OK. $Apache::Server::ReStarting never gets set! - I suppose it's a bug. (I have tried Apache::Server::ReStarting and Apache::ServerReStarting which is the same... I've even tried Apache::Server::Restarting and Apache::ServerRestarting - I know they don't exist) Meanwhile the only workaround is: ReStarting == true if Starting == false Here is the test that you can reproduce: I've added: httpd.conf: -- Perl print STDERR "Perl Apache::Server::Starting is true \n" if $Apache::Server::Starting; print STDERR "Perl Apache::Server::Starting is false \n" unless $Apache::Server::Starting; print STDERR "Perl Apache::Server::ReStarting is true \n" if $Apache::Server::ReStarting; print STDERR "Perl Apache::Server::ReStarting is false \n" unless $Apache::Server::ReStarting; /Perl startup.pl: --- print STDERR "startup.pl: Apache::Server::Starting is true \n" if $Apache::Server::Starting; print STDERR "startup.pl: Apache::Server::Starting is false \n" unless $Apache::Server::Starting; print STDERR "startup.pl: Apache::Server::ReStarting is true \n" if $Apache::Server::ReStarting; print STDERR "startup.pl: Apache::Server::ReStarting is false \n" unless $Apache::Server::ReStarting; when server is started startup.pl: Apache::Server::Starting is true startup.pl: Apache::Server::ReStarting is false Perl Apache::Server::Starting is true Perl Apache::Server::ReStarting is false and in the error_log: Perl Apache::Server::Starting is false Perl Apache::Server::ReStarting is false I'm running the latest CVS (both mod_perl and apache) version on linux with perl5.00503 if it matters. BTW, Doug -- a wish list: I think we need four states: 1. Starting 2. Restarting 3. Running 4. Stopping I needed the 'Stopping' flag for the runwaway processes watchdog if you remember. probably other cleanup and alerting features can be added using the 'stopping' flag. Regarding implementation -- it can be a single variable, with four states.
