Bug ID: 364574
Summary: Infinite loop in DocumentUrlDB::get(...) due to
corrupt database
Product: frameworks-baloo
Version: 5.22.0
Platform: Other
OS: Linux
Status: UNCONFIRMED
Severity: normal
Priority: NOR
Component: Baloo File Daemon
Assignee: m...@vhanda.in
Reporter: stefan.bru...@rwth-aachen.de
CC: pinak.ah...@gmail.com
Somehow a bad entry ended up in the idfilename database, with key == parentId,
name = "". Thus the while(id) loop never terminates.
The key is valid (e.g. points to the device/inode of ~/Pictures), and was
referenced by several children, i.e. the ~/Pictures/ contents.
mdb_dump -n -p -s idfilename /home/stefan/.local/share/baloo/index_bak shows:
/\00\00\00\1d\01\00\00
/\00\00\00\02\01\00\00Music
/\00\00\00\1e\01\00\00
/\00\00\00\1e\01\00\00
Same for a non-corrupt database:
/\00\00\00\1d\01\00\00
/\00\00\00\02\01\00\00Music
/\00\00\00\1e\01\00\00
/\00\00\00\02\01\00\00Pictures
The error is also visible it the idtree database, it lists itself as a subdoc:
/\00\00\00\1e\01\00\00
/\00\00\00\1e\01\00\00/\00\00\00Q\0a\0c\00/\00\00\00i\0a\0c\00/\00\00\00\c9\0a\0c\00/\00\00\00\05?\10\00/\00\00\00YK\10\00/\00\00\00\faL\10\00/\00\00\00\c9M\10\00/\00\00\00YN\10\00/\00\00\00\d1T\10\00/\00\00\00\99\a2\18\00/\00\00\00\f2\c2o\00
Reproducible: Always
Steps to Reproduce:
Steps which lead to the corrupt database are unknown.
Expected Results:
The DocumentUrlDb::get() should ignore such a bad entry, best remove it.
