[webkit-dev] EWS now parses error logs in case of build failure

[Aakash Jain]

Hi Everyone,

I have added the ability to parse error logs in EWS for Windows and WinCairo as well (in https://trac.webkit.org/r265391).

It seems to be working fine. For example, in https://ews-build.webkit.org/#/builders/10/builds/33343, in step #8 WebKit failed to compile. Now, the 'errors' log is also present, containing only 1 line which is the relevant error. Hopefully this would make it easier to spot the relevant errors from large logs.

Please let me know if you notice any issue or have any feedback..

Thanks
Aakash

Normally, it requires some searching through the logs to find the relevant errors. But now, there is another 'errors' log, which contains just the relevant 11 lines (containing error and few related lines to provide additional context).

My further plan is to make this information more readily available, by adding it to a custom designed page which will open on clicking the status bubble https://webkit.org/b/197522
