Bug 53591 – print-vse-failure-logs: "Found 0 VSE Build Logs" and "WebKit/WebKitBuild/obj" is not there

• Status: NEW
• Component: WebKit Misc.

[A. Farber]

Hello,

I'm trying to build with VC++ 2005 Express and WinXP SP3 PC 
(actually I've tried using 2 different PCs).

After I fix the path to the print-vse-failure-logs
(please see the other bug reported by me:
https://bugs.webkit.org/show_bug.cgi?id=53590 )
the build still fails, but I don't see why:

I've been suggested by [e-mail] on the mailing list
to submit this situation as bug report.

At the same time, I've been able to build WebKit on Mac.
So it must be something related to WinXP + VC++ 2005 Express

so there is a build failure, but
print-vse-failure-logs fails to report it

[Adam Roben (:aroben)]

I think print-vse-failure-logs needs to be updated now that the layout of WebKitBuild has changed.

I tried to execute print-vse-failure-logs (after tried to build webkit) and got this error:

It's trying to execute git. Felipe, do you have git installed? Is it in your path?

This seems like a different issue from the one the reporter described.

OK, I installed git now and run print-vse-failure-logs again, and got:

The current directory (/home/Felipe) is not a WebKit checkout, using /home/Felipe/WebKit
Found 0 Visual Studio Express Build Logs:

I think it seems now the same "issue from the one the reporter described".
Thank you.

A. Farber,

You are sure:  there's no a  Webkit/WebKitBuild/obj  directory.  The possible directories you'll find are  WebKit/WebKitBuild/Release/obj  or  WebKit/WebKitBuild/Debug/obj, depending the options passed to build-webkit (--release  (default) or  --debug).

Happens that build-webkit doesn't pass this option to print-vse-failure-logs (as well as print-vse-failure-logs doesn't read such an option).  So there's no way to print-vse-failure-logs know correctly in what directory it should search for logs.

Patched print-vse-failure-logs

Patch for print-vse-failure-logs accept now options "--debug" or "--release".  Lines 114-128 read this possible option, printing help if an error occurs.  Class  PrintVisualStudioExpressLogs  now take one argument "mode", wich can be "--debug" or "--release" or "" (default is "") and is stored as a new attribute  self._mode , so the constructor of the class was changed (lines 47, 49) as well as the call to the class in line 129.  Options "--configuration" (instead of "--top-level") and  self._mode  are passed to the script webkit-build-directory in line 86.  A "# NOTE:" in method "_obj_directory" was removed, since it's obsolete.

New copyright line was added.

For compatibility with former patch

This patch for build-webkit is for compatibility with the patched print-vse-failure-logs.  Now it takes the $configuration (line 582) and pass the correct option to print-vse-failure-logs, depending on $configuration (lines 586-590).  Also line 596 was changed to show the correct directory for build logs.

Sorry, I was not attempt in how to create a patch.
This file contains the desired patches, and I marked old files as obsolete.

*This* is the patch

Can we make print-vse-failure-logs respect the current configuration? I.e., this:

set-webkit-configuration --debug
print-vse-failure-logs

…should cause the Debug logs to be printed.

View in context: https://bugs.webkit.org/attachment.cgi?id=83414&action=review

How do we test this?  We have unit testing for Python and perl, seems we should use it.

> Tools/Scripts/build-webkit:590
> +            if ($configuration eq 'Debug') {
> +                system(File::Spec->catfile($scriptDir, "print-vse-failure-logs"), '--debug');

> +            }

I'm pretty sure that wkdirs.pm has a function for returning --debug or --release from the $configuration information.

> Tools/Scripts/print-vse-failure-logs:126
> +    elif len(sys.argv) == 2:
> +        if sys.argv[1] != "--release" and sys.argv[1] != "--debug":

Seems we should consider using optparse.  It's very easy to do.

Thanks for the patch, btw!

>print-vse-failure-logs

I didn't find a module that could catch the default configuration and pass it to a python script. The only way I see to make print-vse-failure-logs respect the current configuration is making it find "manually" the configuration file, without using a module for it.

>I'm pretty sure that wkdirs.pm has a function for returning --debug or --release from the $configuration information.

Yes, I find a function argumentsForConfiguration, from webkitdirs.pm, that returns an array with configuration options. '--debug' or '--release' is the first element.

>Seems we should consider using optparse.  It's very easy to do.

I'm implementing it.

I tried to compile webkit on win7 32bit with  VC++ 2005 Express  after patching the two patches from 53590 and 53591. But I still got failure, following is the output.
