has anyone else experienced a problem with ~/.sup/sources.yaml being wiped out? it''s gone away on me a few times, though i''m not sure exactly what happens to it. sup hits an error, and either deletes sources.yaml or makes it an empty file. i can''t say which, i just suddenly notice that my sup wrapper script is running sup-add to add a bunch of sources which should already be there, and when i look at sources.yaml, it''s starting to rebuild my supiverse from scratch. i''m afraid i can''t say what caused it, either. the latest time it happened was with an error about draw_screen, but the backtrace was gone too fast for me to grab it. sorry to give you so little information, william. maybe you could check the handling of sources.yaml generally? maybe there''s a place where it''s opened for writing, then never closed before an error occurs? i''ll try to get more details if it happens again. thanks, -- jeff covey http://jeffcovey.net/
ok, it happened again[0] and i was able to catch it this time.
i hit "q" to quit sup while it was in the middle of doing something
(polling
for new messages, i believe), and got this:
[Sun Jun 10 16:07:48 -0400 2007] good night, sweet prince!

after that, my sources.yaml was reset to nothing, and all the associated
problems followed as before.
thanks,

[0] and i had to rebuild my whole sup setup from scratch again. :(

Hi Jeff, First let me say that I really appreciate all the feedback and I''m sorry that Sup keeps breaking in annoying ways for you. Thanks for being patient. Users like you are an asset!

The right answer is to remove all possible the sources of error in that process, but maybe I can also change the code to be a little more resilient.

Let me take a look.I''m still not sure why sources.yaml, of all files, would end up being zero, since the write was pretty atomic, but I''ve now made it even more atomic, so hopefully this shouldn''t happen too often any more. -- William <wmorgan-sup at masanjin.net>
