Deksbar crashes on mounting non-boot partition

Description
hrev33301-trunk;gcc4;acpi;ata-bm; (fresh -qaj2 install)
Since some time Deskbar crashes 9/10 times when mounting my storage bfs partition. When restarting, this happens to. Backtraces differ and sometimes end in libbe, sometimes libroot.
Checkfs reports no issues on the partition.
Can this be related to hrev32894 as I am seeing quite some 0xdeadbeef in some backtraces, otherwise "can't access memory" reports.
Can some threaded be:deskbaritemstatus index scanning cause this which is choking since the heap allocator changes? (I know I have some binaries on the storage partition which previously had their replicants in the Deskbar) Just a gues...

The lines exactly following that are also interesting as they are the rest of the stacktrace. I've seen the same once, but couldn't find a reproducible way to trigger it.

Not sure there was something below that syslog excerpt from above. Will have to recheck when I am home again. Might be there was nothing as I didn't enter gdb when Deskbar crashed, but just left the debug_server alert open and entered KDL for the shot. If you like I can redo it with entering gdb and then going to KDL for the kernel side backtrace
Btw, is there a way to dump output from KDL into the syslog? If not directly, keep in a buffer and write out on KDL exit? So one could circumvent the camera pictures.
comment:5 by , 15 years ago
Ok, either I misunderstand what you meant with "The lines exactly following that..." and I am still not providing all relevant information or there is nothing to more to show. :)
Just retried and got the very same kernel land backtrace for the Deskbar thread. Syslog shows nothing more then what I posted in the previous snippet.
Just point into the right direction if I didn't get it right providing the info you need. Thanks in advance!

Doing a tracker based query with above shows results which shouldn't be listed. See attached screenshot. listattr on these shows no be:deskbar_item_status attribute, except for ProcessController.
Now for the funny part, if I rename a file on my desktop, it appears in the query result as well. Renaming it back to it's old name, removes it from the result list again.

bfs/Query.cpp:1117 allerts to syslog that Inode::GetName() fails. For circumventing the Deskbar crash I am returning a dummy "xyz" name.
I don't have the expertise investigating this, so leaving filesystem "intact" until Axel returns.
I also failed constructing a BDirectory with the parent's dev_t and ino_t information (extended the dump message to get this info) for iterating the parents directory entries in order to find the entry choking. InitCheck() failed.

If the BFS change "fixed" this, then only the symptoms have been fixed - in any case, this points to problems in the file system, so maybe it's not worth to actually fix this in applications.

I didn't do any "fixes in applications". I can't really grasp what you wan't to say with that. Just modifed bfs/Query.cpp which covered the issue and allowed me to "work" normally. Of course, I am not using the modifed bfs/Query.cpp anymore, and your changes have probably fixed the retrieval of the Inode::GetName() which returned "NULL" in case it couldn't be retrieved.

I mean there is probably a problem in your file system that caused GetName() to fail in the first place.
Anyway, I'm closing this bug for now.
Unless you explicitly configured your tree to use malloc_debug this has no influence as it isn't used. The deadbeef you see comes from the kernel in that case, most probably from the disk device manager. When you get that, can you please enter KDL (alt-sysrq-d) and get a backtrace from there (bt <thread>), as the GDB output is most of the time not very helpful. You could also check the syslog for evidence and post that here.
