Description Hiroaki Nakamura 2007-11-03 00:27:33 PDT
Although I was able to build the WebKit successfully, I found a trivial bug in WebKit/win/WebKit.vcproj/WebKit.vcproj and WebCore/WebCore.vcproj/WebCore.vcproj.

Exit code of findstr is 0 when found and 1 when not found. So an correct handling of the result is:

echo foo | findstr foo
if errorlevel 1 (echo not found) else echo found

or

echo foo | findstr foo
if %errorlevel% equ 0 (echo found) else echo not found

I made a patch and will attach it.

Please set the "review?" flag on patches in the future to make sure they're reviewed.  Thanks!

Fix handling results of findstr

Usage of "if ERRORLEVEL" was wrong.
Comment 4 Hiroaki Nakamura 2007-11-03 16:58:39 PDT
I edit my attachment and changed review flag to "+". Is this what you mean? Thanks.

No, set it to ? so a WebKit reviewer knows to take a look at it.  They'll change it to +/-.
Comment 6 Hiroaki Nakamura 2007-11-03 21:01:09 PDT
Oh, now I understand, you had set the review flag which I should have set it. Sorry to bother you and thank you.

Fix handling results of findstr

I'm not sure how the new behavior is different from the old. Before we had:

if ERRORLEVEL 0 set EnablePREfast false else set EnablePREfast true

Now we have

if ERRORLEVEL 1 set EnablePREfast true else set EnablePREfast false

What is the difference?

I also don't think we want "echo on" in our pre-build step.

Fix handling results of findstr

First, "echo on" was my mistake. I forgot removing them.

As for ERRORLEVEL, I read the help of cmd.exe and understand that "if ERRORLEVEL n stmt1 else stmt2" means if errorlevel is greater than or equal to n then execute stmt1 else execute stmt2. And findstr returns 0 when found, 1 when not found. So if you write "if ERRORLEVEL 0", stmt1 is always executed.

Also you need parenthesis if stmt1 is not one word. I tried without parenthesis and it didn't work correctly. I tried on Japanese Windows Vista Home Edition.

And original project file was missing "else" for setting AnalyzeWithLargeStack.

Thanks for the explanation.

It seems to me we could combine the two if/else statements into one. But r=me even if you don't do that. Thanks!
