[Dovecot] zlib plugin weirdness
Hello,
I'm trying to get the zlib plugin working on my 2.0 server. I started with an mbox that Dovecot can read just fine. Then I gzipped it, and now Dovecot complains that it's corrupted:
Error: Next message unexpectedly corrupted in mbox file
/var/lib/vpopmail/domains/memoryhole.net/kyle/Maildir/Archive/Intellego.gz
at 1907
Error: Unexpectedly lost From-line from mbox file
/var/lib/vpopmail/domains/memoryhole.net/kyle/Maildir/Archive/Intellego.gz
at 1907
Error:
zlib.read(/var/lib/vpopmail/domains/memoryhole.net/kyle/Maildir/Archive/Intellego.gz):
unexpected EOF at 1765954
Error: i_stream_get_size() failed with mbox file
/var/lib/vpopmail/domains/memoryhole.net/kyle/Maildir/Archive/Intellego.gz:
No such file or directoryA similar thing happens when I bzip it. I was worried that it wasn't even using the zlib plugin, but since it makes reference to zlib.read, I assume that it is. Does anyone know what might be going wrong?

No, that causes a rather ugly panic:

No, that causes a rather ugly panic:

That does it for gz-compressed files; it works!
However, for bz2-compressed files, I get:
Error: Next message unexpectedly corrupted in mbox file /var/lib/vpopmail/domains/memoryhole.net/kyle/Maildir/Archive/Intellego.bz2 at 1907 Error: Unexpectedly lost From-line from mbox file /var/lib/vpopmail/domains/memoryhole.net/kyle/Maildir/Archive/Intellego.bz2 at 1907 Error: i_stream_get_size() failed with mbox file /var/lib/vpopmail/domains/memoryhole.net/kyle/Maildir/Archive/Intellego.bz2: No such file or directory

I made the change suggested by http://hg.dovecot.org/dovecot-2.0/rev/ab24859c3527 to istream-bzlib.c, and things now work perfectly for bz2-compressed files as well.
