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

[Aakash Jain]

Hi Everyone,

I am happy to announce another EWS feature.

From now on, in case of build failure, EWS will parse the errors and display them in a separate 'errors' log. You wouldn't have to search through thousands of lines of logs to find the error message.

For example, in https://ews-build.webkit.org/#/builders/16/builds/6054, in step #7 WebKit failed to compile. Complete logs (stdio) are 38,000+ lines, and the error is not at the end of the logs. 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).

Hopefully this would save some time and efforts previously spent on searching through the large logs.

Note that this information is not displayed in status-bubble tool-tip, since this might be lot of text to display in the tooltip. 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

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

Thanks
Aakash
