Firebird 5 : gbak with -FIX_FSS_DATA NONE and -PAR (Firebird-5.0.0.1306-0-linux-x64.tar.gz)

[mmoo-Leon-Sanders]

I'm unable to restore a database if it contains -FIX_FSS_DATA Errors whilst using a backup with -PAR
This DB contains an implicit error in one table.

Following fails:
/opt/firebird/bin/gbak -b -se %IP%:service_mgr -user %USER% -pass %PASS% -T %DB% -PAR 16 -V /tmp/dailybackup.fbk
/opt/firebird/bin/gbak -rep -se %IP%:service_mgr -user %USER% -pass %PASS% -V -P 8192 -FIX_FSS_DATA NONE -i /tmp/dailybackup.fbk dailyrestore
--- The backup works however the restore fails and raises an error to fix the fss_data

Following works:
Just removing the -PAR 16 in the backup the database is successfully backed-up and restored (with and without indexes -i).

gbak: 473.811 0.302 0 136 445000 records restored

From what I can gather using -PAR changes the backup file in a way that -FIX_FSS_DATA NONE will not work when restoring it.

Could you try with latest snapshot build ?
Could you provide core dump of crash, or stack backtrace from it ?

Just a side note: -FIX_FSS_DATA NONE is a complete nonsense, I hope you used it for example only.

Sorry for the confusion.
I tried to restore and it errored out with malformed UNICODE_FSS so I reran the restore with the param to fix the UNICODE to NONE. This worked and fixed the restore, but only when the backup was created without -PAR

gbak:restore options are:
-FIX_FSS_D(ATA) fix malformed UNICODE_FSS data
-FIX_FSS_M(ETADATA) fix malformed UNICODE_FSS metadata

I'll try this weekend..

I re-open the issue as it is not clear what really happens. Waiting for more details.

Any news ?
