Hi all!
Back in december Thomas fixed a bug which made decrypt-save delete the
message even if the decryption hadn't been successful. The commit
message was:
> 2004-12-21 09:46:24 Thomas Roessler <[EMAIL PROTECTED]> (roessler)
> * pgp.c: Fix Debian #275188.
If you read the bug log, it seems that after some discussion between
Thomas and Tamotsu, the bug was finally declared fixed (and they
discovered that there was a remaining bug in the decode-save function).
However, I can still reproduce the bug. Can anybody confirm?
The patch, afaict, was:
--- a/pgp.c 2005-01-14 21:18:18 +01:00
+++ b/pgp.c 2005-01-14 21:18:18 +01:00
@@ -830,6 +830,10 @@
*cur = pgp_decrypt_part (b, &s, *fpout, p);
rewind (*fpout);
+
+ if (!*cur)
+ return -1;
+
return (0);
After some investigation, I've found that, while that fix was
necessary, it is not enough, since pgp_decrypt_part(), in its current
form, does never return NULL. This is because, unlike in the rest of
pgp.c, the return of mutt_wait_filter() is not checked.
I attach a patch that seems to fix the issue, comments welcome. I've
checked that pgp_decrypt_part returning NULL is handled gracefully in
the other invocation of it.
Thanks.
