Where does GoogleAppEngineLauncher keep the local log files?
Many of these answers are now outdated. :)
In today's devappserver, use --logs_path=LOGS_FILE if you want to log to a file (in its native sqlite database format). Or as suggested in a comment, simply pipe the output if that's too complicated.
Since there's a log API, it actually now stores log entries in a file in --storage_path if not set. I have noticed a few bugs myself, though. (I'll assume they don't exist now, it's been a while since I used this.)
GoogleAppEngineLauncher can display the local log file of my app while it is running on my Mac during development. However, I can't change the font size there so I would like to use the tail command to watch the log file myself.
It's a shame but I can't find the log files. They are not under /var/log/, ~/Library/Logs or /Library/Logs. Do you know where they are?
(Maybe there are no physical files, just the stdout of the python development environment and so the log is only available in the launcher application.)
