Bug 176686 – Remove duplicated test results from LayoutTest platform directories

• Component: Tools / Tests
• Status: RESOLVED FIXED

[Carlos Garcia Campos]

After several rebaselines we might end up with the same result in the platform directory than the common result without noticing it. I've written a script to detect those cases and remove all the duplicated results from the repository. The current status is:

$ Tools/Scripts/check-for-duplicated-platform-test-results -n | grep found
5 found in platform mac-yosemite
15 found in platform win-7sp0
2 found in platform win-future
110 found in platform wpe
2 found in platform mac-highsierra
8 found in platform mac-elcapitan
142 found in platform win
2 found in platform mac-wk1
21 found in platform ios-wk2
147 found in platform mac
3 found in platform mac-wk2
2 found in platform ios-11
20 found in platform ios-wk1
109 found in platform ios
237 found in platform gtk

It seems the script is not smart enough...

[Carlos Garcia Campos]

I guess it's because when removing the expected results for mac-elcapitan, it's comparing to what there's in mac platform instead of common results. The script needs to know the relationships between platforms and check for theses particular cases. Or maybe in these cases we should add the different result to the most specific platform dir that produces a different result.

Does this work the other way around too? I mean, for example for platform mac-elcapitan the search path is:

mac-elcapitan -> mac-sierra-wk2 -> mac-sierra -> mac-wk2 -> mac -> wk2

so, any rebaseline in mac-elcapitan subdir that is exactly the same as the one in mac could be removed too as long as there isn't a different result in mac-sierra? even if it's not the same as the main result? If my script is not wrong there are currently 267 of those.

Nevermind, my script was indeed wrong :-P

[Carlos Garcia Campos]

With a new version of the patch that checks the baseline search paths this is what I'm getting now:

$ ./check-for-duplicated-platform-test-results -n | grep "found in"
240 found in gtk -> wk2 -> generic
13 found in mac-yosemite -> mac-elcapitan -> mac-sierra -> mac-wk1 -> mac -> generic
5 found in win-7sp0 -> win -> mac -> generic
193 found in win -> mac -> generic
110 found in wpe -> wk2 -> generic
3 found in mac-wk1 -> mac -> generic
7 found in mac-elcapitan -> mac-sierra -> mac-wk1 -> mac -> generic
3 found in mac-wk2 -> mac -> wk2 -> generic

I'm not sure about the win tests, and they can't be tested with EWS, so I'll submit a new patch with the new version of the script and the duplicated removes for all platforms except win.

Nit: please don't switch between using single quotes and double quotes for strings in the same script. I would stick with single quotes, since that's what most of our WebKit scripts use, and using single quotes also matches the GNOME style to use double quotes only for translatable strings.

> Tools/Scripts/check-for-duplicated-platform-test-results:110
> +    print "%d found in %s -> generic" % (duplicates_len, " -> ".join([os.path.basename(p) for p in baseline_search_path[:-1]]))

And here you've switched back to double quotes, though you used single quotes for most of the script.
