Skrooge is a personal finances manager for KDE4, aiming at being simple and intuitive. It allows you to keep track of your expenses and incomes, categorize them, and build reports of them. Skrooge is a part of KDE Extragear, in the Office module

This page is dedicated to developpers or advanced users who wish to have a deeper understanding of Skrooge.

Debugging

Trace activation

To activate traces, you need to export an environment variable in your console:

export SKGTRACE=XX

XX is the level of traces you want. It should be an integer between 0 and 20. The higher the number, the higher the quantity of information you get. 10 is good compromise.

Then, start Skrooge from this console. This will display a lot of information in your terminal, giving you hints as to what could be going wrong if you face issues.

Profiling

To activate the basic profiling mechanism included in Skrooge, you need to export an environment variable in your console:

export SKGTRACEPERFO=1

Once Skrooge is started from this console, you can find two new commands:

• Restart profiling (CTRL+Pause) to initialize the profiling
• Open profiling (ALT+Pause) to open the result of the profiling

Profiling results look like this:

_{method , nb call , millisecondes , average , min , max , own time , average own time SKGMainPanel::setNewTabContent-addTab , 1 , 38.26897848 , 38.26897848 , 38.26897848 , 38.26897848 , 25.6370585 , 25.6370585
SKGObjectModelBase::refresh , 2 , 8.741794825 , 4.370897412 , 0.9698964357 , 7.771898389 , 8.147958875 , 4.073979437
SKGMainPanel::setNewTabContent , 1 , 49.36599612 , 49.36599612 , 49.36599612 , 49.36599612 , 3.772916079 , 3.772916079
SKGOperationBoardWidget::SKGOperationBoardWidget , 1 , 3.179117203 , 3.179117203 , 3.179117203 , 3.179117203 , 2.963078141 , 2.963078141
SKGMainPanel::onOpenContext , 1 , 50.43999612 , 50.43999612 , 50.43999612 , 50.43999612 , 1.074000001 , 1.074000001
...}

Remark: If SKGTRACE is set then you will be able to find the execution time of each methods in traces.

To profile only sql instructions, you can export an environment variable in your console:

export SKGTRACESQL=XX

Only sql order with an execution time greater then XX ms will be displayed in console.

In the console, you will get something like:

_{executeSqliteOrder :SELECT t_name, t_TYPENLS, f_CURRENTAMOUNT, t_close from v_account_display WHERE (t_type='C' OR t_type='D' OR t_type='I' OR t_type='O') ORDER BY t_TYPENLS, t_name TIME=441 ms}
