#47804 db2bak.pl error with changelogdb
Closed: wontfix None Opened 8 years ago by orion.

We are backing up our database daily with db2bak.pl, and have started to notice the following messages:

[13/May/2014:03:59:08 -0600] - Backend instance "changelogdb" does not exist; Instance path /var/lib/dirsrv/slapd-cora/changelogdb could be invalid.
[13/May/2014:03:59:08 -0600] - Backup: error in copying directory (/var/lib/dirsrv/slapd-cora/changelogdb -> /var/lib/dirsrv/slapd-cora/bak/cora-2014_05_13_03_59_08/.repl_changelog_backup): err=-1

Noriko reproduced with master as well.


Bug description: Backup utility db2bak[.pl] copies not just backend
db files but also changelog db files, which is not associated with
the backend instance, but the backup code blindly expected it.

Fix description: If the copying directory is a changelog db dir,
skip retrieving the backend instance info and just copy the files
underneath.

in dblayer_copy_directory, is it possible that a NULL inst could be referenced?

Replying to [comment:3 rmeggins]:

in dblayer_copy_directory, is it possible that a NULL inst could be referenced?

I believe we are safe on that.
1) if is_changelog and not the path is not a fullpath, it returns there without going further.
2) if not is_changelog and inst is NULL, it returns there.
3) if not a fullpath and inst is NULL, dblayer_get_full_inst_dir returns NULL and dblayer_copy_directory returns there.
4) dblayer_copy_file_resetlsns called from dblayer_copy_directory calls dblayer_copy_file_keybykey, in which NULL inst is checked before referenced.
