Tracefile

In the GnuCash application, all error messages during the program run are redirected into a trace file. The content of this file is very important when reporting a bug, as well as a Stack Trace for bugs that crash the program.

At each program start, a new trace file will be written and all output during the program run will be appended to that file.

Trace file on Windows

On Windows, these files are located in the folder c:\Documents and Settings\myname\Local Settings\Temp\gnucash.trace.ABCDEF for a user named "myname" (on Vista in C:\Users\myname\AppData\Local\Temp), where the .ABCDEF suffix is changed randomly on each start of gnucash. This location may change, if you set the Windows environment variables TMPDIR, TMP, or TEMP (in DOS mode, use the SET command). Also, the folder name "Local Settings" might be named differently in your native language (e.g. in German "Anwendungsdaten"), and it might also be a "hidden system folder" which is shown only if you change the folder properties to "Not hide system files/folders".

If you experience crashes or unexpected behavior, check the latest of these files (or the one created when the problem started) and add all interesting-looking lines of that file to your error reports (e.g. in Bugzilla). Please include at least the lines with the keywords WARN (for warning) and CRIT (for critical warning).

Trace file on Linux

On Linux, these files are located in /tmp.

Trace file on OSX

On OSX, Gnucash creates the tracefile, gnucash.trace, in the operating system's current temp folder, located in /var/folders. The rest of the path has the form yy/yy_lots_more_hex_characters/-Tmp-/gnucash.trace. Most systems have several of these, so the easiest thing to do is to open Terminal and run

$ find /var/folders -name gnucash.trace

and it will print out the path for you.

Trace File Adjustments

Running

gnucash --help

in a command shell will give you a clue of possible options:

• --debug: Enable debugging mode: increasing logging to provide deep detail.
• --extra: Enable extra/development/debugging features.
• --log: Log level overrides, of the form "log.ger.path={debug,info,warn,crit,error}"
• --logto: File to log into; defaults to "/tmp/gnucash.trace"; can be "stderr" or "stdout".

So, if gnucash --debug is not sufficient, gnucash --debug --extra might be.
