Is anyone here besides me actually using a (lousy) LaCrosse 23xx weather station and the open2300db2APRS program we have bundled in the Xastir source?
I just upgraded the OS on my primary system and discovered that open2300db2APRS started segfaulting afterwards. Turns out there's a huge error in how that code accesses the mysql database, and I'm amazed it ever worked at all --- but it did for me for several years until tonight's upgrade. Specifically, the code never actually issued the mysql_fetch_row command after querying the database for weather data --- and then started pulling data out of the row datastructure, and apparently got what it was expecting. This definitely doesn't work in the version of os that I updated to (MySQL 5.1.41 on FreeBSD 7.2, previously running MySQL 5.1.41 on FreeBSD 6.4 --- all I did was recompile mysql on the new system, and boom, segfaults from open2300db2APRS). I'm pretty sure that the changes I had to make to my local copy of open2300db2APRS to get it to work after the upgrade would be correct even for older versions of mysql, and that it's likely it only worked because of a fluke. My change is merely to fetch the row after the query. If anyone else is actually using this code now, lemme know. I'll commit my changes and work with you to make sure they don't break your currently working build. I can't imagine it will, but I figure a head's up is in order first. -- Tom Russo KM5VY SAR502 DM64ux http://www.swcp.com/~russo/ Tijeras, NM QRPL#1592 K2#398 SOC#236 http://kevan.org/brain.cgi?DDTNM In some cultures what I do would be considered normal. -- Ineffective daily affirmation _______________________________________________ Xastir mailing list [email protected] http://lists.xastir.org/cgi-bin/mailman/listinfo/xastir
