in reply to Maintaining sessions with WWW::Mechanize across script instances?

I don't think I'd try to serialize/deserialize complicated data structure unless I knew it like the back of my hand. There are some things in perl that just can't be serialized like that. If you need it to persist, I suggest a job server like POE or a mod_perl process and storing the object in global memory. Before that though, I'd try to figure out how to store the object state and then try to reinitialize a new instance of the object. Either of those is going to be faster than dumping the raw object and reading it back.

As far as the cookies, did you look at the cookie file to make sure it looks like you want it to? You may have to muck with the WWW::Mechanize internals. But its just a wrapper around LWP, so it is pretty simple to do. I'm sure a glance at the source for those methods and maybe a couple of debugging sessions will show you what the problem is.

[perldigious]: karlgoethebier: Well it is a pretty old and complicated (for me) bit of code I wrote (poorly by my current standards), so I'm expecting everything to break when I add the scoping and find out what else is undesireably scope changed. :-)
[perldigious]: Ah, thanks choroba, that sort of thing was precisely what I was wondering when I asked.
[perldigious]: I didn't want to tie up memory unecessarily basically, I wanted to "delete" it specifically to free it up, and wasn't sure I was even accomplishing that.
[stevieb]: perldigious You should start by writing some unit tests. That'll ensure current functionality doesn't break with changes.
[choroba]: unit tests++
[choroba]: The only problem you can't solve by adding more tests is the problem of having too many tests.
