Furthermore, the manpage for the mustek_usb2 is present even though the actual backend is missing. That's quite misleading, so I'd consider this a true bug. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

I do not have this model but when I select this model in the list of all models in the YaST scanner module everything works prompt in YaST (in particular nothing hangs up) but of course because of the missing driver it cannot work to scan with a "BearPaw 2448TA Pro". http://groups.google.de/group/alt.linux.suse/msg/881688e47c586b75 reads "die Scanneraktivierung läuft bis 100%. Beim klicken auf Benden ist alles wieder verschwunden." i.e. there is no hang up at all (or how would he click "Beenden") if it was actually hang up. Therefore I cannot reproduce your reported bad effects. I change it to a "minor" bug because the mustek_usb2.desc file leads to wrong information in the YaST scanner module which confuses users. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

New subject: [Bug 633780] sane-backends contains misleading mustek_usb2.desc file

https://bugzilla.novell.com/show_bug.cgi?id=633780 https://bugzilla.novell.com/show_bug.cgi?id=633780#c3 Johannes Meixner changed: What |Removed |Added ---------------------------------------------------------------------------- Summary|sane-backends package lacks |sane-backends contains |mustek_usb2 backend |misleading mustek_usb2.desc | |file --- Comment #3 from Johannes Meixner 2010-08-27 12:36:11 UTC --- I asked on the sane-devel mailing list regarding "pros and cons regarding --enable-pthread for Linux" and the answer was: ----------------------------------------------------------------------- Pthread is the default on other platforms because they generally don't let open usb device handles pass across a fork(). Since this works on Linux, and threads were so flaky all those years ago, non-threaded became the default for Linux. Honestly, I think it could be changed, but I don't think pthread is as well tested, since most user's use whatever their distro compiles :) ----------------------------------------------------------------------- Currently it is unknown what possible bad sife effects "--enable-pthread" could have and the above comment does not look very promising.

...

From my point of view general reliability for all other models is much more important than one single more supported model.

Therefore I will not use "--enable-pthread", at least not for now. Instead I will remove the mustek_usb2.desc file to avoid that the YaST scanner setup module lists this model. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

New subject: [Bug 633780] use "--enable-pthread" for sane-backends (required by mustek_usb2 backend)

...

...
sane-backends in Debian has been using pthread since Feb 2009.

I assume there have been no issues because of this (otherwise you would have told us).

Nope, no issues so far.

...

Now I think about --enable-pthread for the next openSUSE version and if there are bug reports because of this I could switch back to the default.

Threads are actually better from a "least surprise" PoV; big applications are already threaded so it's not an issue for them, small applications aren't threaded so it's usually not a problem here either. fork()ing, on the other hand, can have quite some side-effects. ----------------------------------------------------------------------- see the sane-devel mailing list thread about "pros and cons regarding --enable-pthread for Linux" Therefore for openSUSE 11.4 beta phase I will use "--enable-pthread" and then let's see if we get reports about issues... -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
