[request] Find failed: more features for debugging

[Erick Quinteros]

Version: Sikuly finally 1.0.0
OS: Windows 7 64-bits
Reproduce: Execute find operations for a long period of time.

When I use the find operation (or others than use find inside) on a automatized scenario during long periods of time, the find operation fail in some point, if I try to find the image again is found but in a long execution it fails, and not always the same image fail.

FindFailed exceptions are only raised/thrown, if a (explicit or implicit) search (explicit or implicit) for an image on the screen is not successful within the given wait time (in the standard 3 seconds).

In long running situations, there might be other system aspects that eventually lead to a delay of the GUI actions and hence to a FindFailed. This can only be debugged, if you take care, that a screenshot of the FindFailed situation is available afterwards (e.g. the latest screen image used to search).

Currently, there is no compact feature in Sikuli to support such a tracking. You must setup your own function and use it instead of all (or at least the critical ones).

Another option is to replace all find operations with wait(image, maxtime)

e.g. instead of
click(some_image)

use
click(wait(some_image, 20))

which does not do any harm, since it will come back in the moment the some_image appears, but add some robustness for situations, where the image's appearance is delayed for a reason you cannot foresee in your script.

I accept this as a request bug in 2 directions:

1. provide better tracking/documentation options for search operations

2. support some dynamic automatic adjustment for the waiting time, based on e.g. cpu-usage level and/or average search times up to now.

I implemented a "waiter" to wait until no changes occur in the screen and this method avoid the posibility to use a find operation when the screen is not ready. That is not the problem, when i use the sikuli rc2 this don´t fail, I start having problems when I upgrade to the new sikuli version. I will continue looking for a workaround or a fix and I will give you more feedback.

[RaiMan (raimund-hocke)]

I understand:
in RC2 you have a waiter method, that lets find operations wait until the screen is ready.

If I understand right: could you share this method with me?
