Calibre debug file

meme · 02-01-2011, 03:37 PM

For some reason I can't seem to find the debug file created when running the comand line:

Code:

calibre-debug --gui-debug=GUI_DEBUG

I've looked for GUI_DEBUG, and tried ./filename or filename and still no luck. I'm running on Ubuntu 10.10. And tried using the --show-debug option but no luck there either. When Calibre starts up a dialog is shown saying the file GUI_DEBUG (or filename, etc.) will be created and automatically displayed. But it doesn't seem to be created - it also isn't displayed (although I can see the debug output in the terminal window I used to start Calibre).

It works fine if I use the GUI menu option to restart in debug mode - the /tmp file gets created and gets displayed after logging out and can be edited.

I must be missing something obvious. Any pointers?

My guess would be that the file gets created either in the current working directory of the shell you called the program from or in Calibre's bin directory.

Edit: I just tested. The debug file doesn't get displayed for me, as well.

Edit2: I guessed wrong. A search didn't find the file. There's another way to create a logfile that should work: Invoke "calibre-debug -g > filename", that should redirect the output to the filename you selected. This will be created in the current working directory, unless you specify an absolute path.

Yeah, I've been using "calibre-debug --gui-debug=GUI_DEBUG | tee out " to capture it - good to know there's a '-g' to use - I just added the tee in the script and left it since it worked, but was curious if I was just misreading the options.

I don't think you're misreading anything, you may have found a bug. Either that, or we both misread something.

There is no debug file created by calibre-debug -g

debug output is printed to stdout snd stderr use

calibre-debug -g 2>&1 > log.txt

Or relaunch calibre in debug mode by clicking the arrow next to preferences, in which case a debug file will be created and automatically displayed after you quit calibre.

No, but shouldn't calibre-debug --gui-debug=filename create a debug file called filename?

Ah no, that option and --show-gui-debug are both for internal use. I'll add a note to the help for those options.

Oh, okay. In that case, to conclude @OP: Go with the calibre-debug -g > outputfile option.
