NAME
dupdb-admin - Manage the duplicate database for apport-retrace. SYNOPSIS
dupdb-admin -f dbpath status dupdb-admin -f dbpath dump dupdb-admin -f dbpath changeid oldid newid DESCRIPTION
apport-retrace(1) has the capability of checking for duplicate bugs (amonst other things). It uses an SQLite database for keeping track of master bugs. dupdb-admin is a small tool to manage that database. The central concept in that database is a "crash signature", a string that uniquely identifies a particular crash. It is built from the executable path name, the signal number or exception name, and the topmost functions of the stack trace. The database maps crash signatures to the 'master' crash id and thus can close duplicate crash reports with a reference to that master ID. It also tracks the status of crashes (open/fixed in a particular version) to be able to identify regressions. MODES
status Print general status of the duplicate db. For now, it only shows the time when the database was "consolidated" last, i. e. when the bug states (open/fixed) in the SQLite database where updated to the actual states in the bug tracking system. dump Print a list of all database entries. changeid Change the associated crash ID for a particular crash. OPTIONS
-f path, --database-file=path Instead of processing the new crash reports in /var/crash/, report a particular report in an arbitrary file location. This is use- ful for copying a crash report to a machine with internet connection and reporting it from there. This defaults to ~./apport_dupli- cates.db. AUTHOR
