#9744 closed Bug Report - Crash (Fixed)
segfault on mythtv-setup
| Reported by: | Robert Kulagowski | Owned by: | danielk |
|---|---|---|---|
| Priority: | minor | Milestone: | 0.25 |
| Component: | MythTV - Mythtv-setup | Version: | Master Head |
| Severity: | medium | Keywords: | |
| Cc: | Ticket locked: | no |
Description (last modified by )
System: Ubuntu 10.10, MySQL 5.5, git trunk, make distclean, configure, make
mysql -uroot -p < database/mc.sql
No mysql.txt or config.xml in .mythtv
/etc/mysql/mysql.cnf is configured with bind-address=10.23.10.222, but the default value specified in mythtv-setup is localhost:3306, and the upper portion of mythtv-setup window states that it could not connect to the database, with a truncated error message to the user. Setting the specified IP address from localhost to 10.23.10.222 will still cause a segfault later.
Other combinations attempted (all result in a segfault) localhost : 0 10.23.10.222:3306 10.23.10.222:0
If you continue through the screens and click "Finish" mythtv-setup returns to the language selection screen. Once returned to the language selection screen mythtv-setup segfaults on the next keypress:
$ gdb -x gdbcommands mythtv-setup

mythtv-setup should not allow the user to continue configuration if the initial connection to the database can't be made, because it will result in a segfault.
The other issue is that the existing documentation can result in the user making modifications to my.cnf to enable connectivity for multiple systems, but if the resulting grant privileges aren't done correctly then the user can still get into the situation where they can't bootstrap themselves and end up in a mythtv-setup segfault.
This may be a moot issue if mythtv-setup goes away due to the www rewrite.

Log:
Fix segfaults on MythUI startup config screens.
ShowOkPopup?() was caching the screen stack.. but this pointer became invalid after the MythMainWindow? was deleted.
