Hi all,
I did some checks today to see if my sitescooper installation was behaving
'as advertised' with respect to caching. It wasnt.
After some debugging, I found 2 problems...
The first one has already been reported on the list, but its effect on
caching has not (IIRC) been pointed out. I'm running on Win2K using the
multipage plucker format and getting the following error:-
eval failed: Usage: Win32::Process::constant(name) at
C:/Perl/lib/Win32/Process.pm line 113.
Unfortunately this trashes the tail end of the sitescooper run, before the
cache entries get committed to the DB file.
This error seems to be a problem with PDA::PilotInstall's invocation of
Win32::Process. I dont know exactly what the problem is, but then I dont
actually want the installer to run. Sitescooper seems pretty persistent at
trying to run it, but I eventually managed to dampen its ardour by adding
the following to sitescooper.cf:-
PilotInstallApp: ***ADD_TO_MANIFEST*** junk.jnk
Unfortunately, the caching still didnt work as expected after doing this.
More debugging found the problem. In CacheSingleton.pm there's a method
called get_cached_page. The first thing it does is prefix its parameter
($ptr) with the name of the page cache directory. The snag is that $ptr
already has the directory in it.
commenting out this...
# my $pagefile = $self->{factory}->{pagecachedir}.$SLASH.$ptr;
and replacing with this...
my $pagefile = $ptr;
caused caching to start working as expected.
What I'm not sure of is whether the above fix fits in with the intended
design of CacheSingleton (it might be that $ptr shouldnt have the directory
in it in the first place).
I also dont know whether the problem exists on platforms other than Win2K
and whether the same fix is applicable.
Anyway, I'm now able to scoop a lot faster.
Regards, Andy
