WebSocket server should write errors to a log file

• Component: Tools / Tests
• Status: RESOLVED FIXED

[Mark Rowe (bdash)]

It’s currently difficult to work out what is going wrong if the WebSocket server fails to start.  If it wrote its errors to a log file in a similar fashion to what Apache does it would be easier to debug issues that only happen on inaccessible machines (eg, the build bots).

Hi,

I've started addressing this upstream:
http://code.google.com/p/pywebsocket/issues/detail?id=24

After it is done upstream, I'll upload a WebKit patch to upgrade
the pywebsocket copy in WebKitTools to the latest.

Hi, reviewers,

Can you review this patch?

Since this is perl, I'd prefer if someone else looked at it. (btw, Yuzo, it is a holiday in the US for Thursday and Friday so expect slower responses.)

Looks OK, but why are we coyping this code from elsewhere?  It should be abstracted into a sub routine.

I see this in the file already:

1380	    my $absTestResultsDirectory = File::Spec->rel2abs(glob $testResultsDirectory);
1381	    my $sslCertificate = "$testDirectory/http/conf/webkit-httpd.pem";
1382	
1383	    mkpath $absTestResultsDirectory;

Thank you for reviewing this.

Refactored by extracting a method.
Can you take another look?

I'll try to think of a better name for makeAbsTestResultsDirectory(), and will land manually. The current name is not great for several reasons:
- we don't like abbreviations in names;
- it's not an "absolute directory" that this method makes;
- nothing in the name suggests that there will be a return value.
