Re: [AOLSERVER] Help with nsimap

Matthew Walker Wed, 19 Mar 2003 13:50:57 -0800

Vlad,

thanks for your help.

Try this:

- when you open mailbox specify /debug option, it will output all client
IMAP
  communication into log file, so we can spot the place in c-client it
dies.
  Example ns_imap open -mailbox {{localhost/debug}INBOX}


I tried this and it didn't seem to do anything, do I need to alter
the debug param in the aolserver startup file ? It is currently set
to 1.

- run aolserver under debugger, to do so you can do:

bash-2.05b# gdb

(gdb) cd /usr/local/aolserver
Working directory /usr/local/aolserver

[New Thread 8192 (LWP 20584)]

Replace path oss2/etc and oss2/logs to log file and config file
according to your installed system
and instead of vlad use your user for aolserver.
Once it started run your script, after crash in gdb run bt command, it
should show the place
it crashed.

BTW: try the latest ns_imap from my site, recently i fixed one possible
crash error.

I have grabbed the latest one and recompiled, all the tests are done with this.

Running in gdb I get:

__strnlen (str=0x58 <Address 0x58 out of bounds>, maxlen=33)

116     ../sysdeps/generic/strnlen.c: No such file or directory.
        in ../sysdeps/generic/strnlen.c

The output from the bt command in gdb:
