[See Bugtracker] Question: Why does JDownloader save all captcha images??

Im curious for quite some time now:

Why does JDownloader save all captcha images??

every now and then i delete several hundets of files in my ~/jd_home/captchas folder... in which all captcha images are saved...

why is that and are they needed anymore???
just for the possibility the same captcha could come up again? if so - does jd remembers the captcha-solution?

atm im thinking about a cron-job to periodically delete all those images...
any reason not to do it?

edit: if they are not needed anymore it would be nice to have an option so jd deletes those unneeded files automatically....

jd does delete all captchas itself. only if jd does not exit normally the images gets not deleted. the jvm deletes the files.

actually this is not an answer to my question why jd saves those files at all... but for a program like jdownloader - which is intended to run 24/7 - imho its pretty bad to only clean up unused files on a "clean" exit.... if i let jdownloader run for a week... my home partition gets filled with old captcha images??? (that they will be deleted on a clean exit wont make it better!)

will get that cron job started to take care of it...

Oh really? I thought it was a heuristic thing for learning captchas.

the captcha files received with the Plugin#getLocalCaptchaFile() has already the deleteOnExit() flag enabled! so which captcha files do you talk about?

deleteOnExit() flag : too late, I think

well even after exiting jd "normally" - there are always a few hundred captcha-images left in my "captchas"-folder.... so i think they wont be deleted anyway!

copy that!
captcha solved - kill it with fire!

edit: btw the exact same thing happens to all dlcs from linksave, urlcrypt etc... they are all left in the tmp folder.. even for files finished several days and restarts ago....!!

deleteOnExit means they will get deleteted when vm shuts down. in case jd gets killed those files will not get deleted and those are the files that you still can see in tmp folders then.

I am truly sorry to unearth this posting but on my Mac the captchas are not deleted. Is this the default behavior of the nightly version or should I file a bug?

In theory they should be deleted when you exit jD but that doesn't always happen.

You can file a bug but I think it's already known. The Bug #2305 "delete captcha" should be opened again.

there has been a bug i already found and fixed, wait for next nightly

Hate to say it but this is still a problem, these files are not deleted, yes proper exit included.

Was cleaning up some old files from my drive and wondered why jdownloader was 274 Mb big, thought it was backups (only 6 Mb) but turned out to be 208 Mb big captchas folder with, wait for it… 71.607 files in it! (Kinda sad seeing that I've solved that many captchas over the years, what an incredible waste of time)

jdownloader version: 0.9.581 running on Mac OS X 10.7.3

Nightly and Stable wont get an Update anymore (only Plugin Updates like the last Years). Pre Beta of JD2 is out, and Devs only work on JD2.
