Load.pm patch

Hi list.

Since I'm using Apache::ASP::Loader to precompile scripts and doing so
via NFS, it kind of took a long time.
Most of it was spent not compiling scipts, but traversing files and
directories which is still painfully slow on NFS.
Since a few of them contained about 2500 images, there should be no need
for Loader to look into them, so I added an argument to Loader
``Ommit_Dirs'' whose value should be a reference to an array containing
dirs the compiler should ommit.

I think it is reasonably useful and I *suppose* I haven't messed up, but
please look into it if you're interested.

Regards,
Thanos Chatziathanassiou

It does seem useful. My work around before has been to programmatically call
Apache::ASP->Load on only the directories that I want to be read fully. Can
this approach work for you without adding this config? Otherwise let me
consider your patch when I get back from vacation. I would think another name
like ExcludeDirs might be better, but I'll check it out for another possible
solution as well.

Regards,

Josh

It could, but I'm probably too lazy to do it like that :)
You see, the directory structure I have is like this:
htdocs/
domain1
domain2
images/lots_of_images
irrelavant_files/lots_of_html
...
domain N
etc, so I feed the Loader the directive to compile all asp's in
/usr/local/httpd/htdocs/, which all more or less have some scripts to
compile in them.
Problem is, they also have directories I wouldn't want the Loader to
spend time looking in.
So instead of repeating the directive N times, I thought of this. I'm
sure all of us can live without it, but it did cut 40 secs out of the 3
minutes it takes to recompile all the scripts by just listing 3
directories in there.

I suppose ``ExcludeDirs'' is a better name...
OTOH, if you want to avoid another configuration directive, it isn't
really a problem.
Have a nice vacation !

Actually, now that I come to think of it, it won't work: there are sites
with a number of scripts in their root directory and a subdirectory of
root filled up with other stuff, so these cannot be selectively added...

What about doing something like:

for my $file_or_dir (glob(qw(/path/to/root/*.asp)), /path/to/other) {
Apache::ASP->Load($file_or_dir, '.*', %config);
}

Since files can be loaded as well as directories?

I see your point, if we have to list directories anyhow, why not list
the ones Load() will have to dive into ?
I kind of like the idea of Load() descending into subdirectories unless
told otherwise, since e.g. our graphics team can copy & paste a contact
form and the relavant .asp file into a client's new subdirectory, edit
the presentational aspect and actually expect it to work. Plus I think a
new-ish user will appreciate the convinience.

It's not that I have given it very much thought, more of an idea than
anything else...
