Normally we'd omit the outer parentheses here.

Is there no way to detect that we are building Windows 64? Also, these paths diff only in there prefix. It seems extraneous to repeat the value twice just because of the difference in prefix.

I also agree with Adam Roben about omitting the outer parentheses here.

I'm sure there is a way, but I'm not a windows environment or perl expert. I just had to run the layout tests on win and this got me building. I've added a FIXME comment.

> Also, these paths diff only in there prefix. It seems extraneous to repeat the value twice just because of the difference in prefix.

I've cleaned up that part.

Thanks for going back and creating a new patch. I have some minor nits:

I would change this to read "Look in /proc/registry64 for the Platform SDK on 64-bit Windows."

I would move the bug URL line so that it appears after the "Reviewed by NOBODY (OOPS!)." line:

The names of these variables seem a bit vague, maybe rename them to $registry32Path, $registry64Path?

I would append "/" to the end of both of these values then remove the "/" at the beginning of the value for $windowsPlatformSDKRegistryEntry so that $windowsPlatformSDKRegistryEntry better resembles a Windows registry path when we print it in the error message "Cannot find ...."

> +    my $windowsPlatformSDKRegistryEntry = "/HKEY_LOCAL_MACHINE/SOFTWARE/Microsoft/MicrosoftSDK/InstalledSDKs/D2FF9F89-8AA2-4373-8A31-C838BF4DBBE1";

As aforementioned, I would remove the leading "/" in the value for $windowsPlatformSDKRegistryEntry.

Since we are no longer using a fixed file system path, I would suggest changing the error message line to read:

print "Cannot find registry entry '$windowsPlatformSDKRegistryEntry'.\n";

r=me.

The prepare-ChangeLog script puts the description before the bug URLs. The majority of ChangeLog entries seem to follow that pattern as well. Can you explain the rationale?

You are missing a ':' after FIXME in the comment, which is necessary for some editors, such as Xcode, to notice that this is a special comment.

Since the last line of this comment is only one word, I would suggest collapsing it into the second line and push the word "and" (at the start of the second line) into the first line so that the two lines are roughly the same size.

Also, I think it might be a bit clearer to write the first sentence as "It would be better to detect whether we are using 32-bit or 64-bit Windows ...":

# FIXME: It would be better to detect whether we are using 32- or 64-bit Windows
# and only check the appropriate entry. But for now we just blindly check both.

I inadvertently left this out of my last comment.

The rationale is that someone does not have to read through the entire description to find the bug URL.

From my understanding of <http://webkit.org/coding/contributing.html#changelogs>, and the example it references <http://trac.webkit.org/changeset/43259> the order is bug name, bug URL, then bug description. A more recent example of this ordering is change-set 59798: <http://trac.webkit.org/changeset/59798>.

I meant "description", not "bug description", as the description in the change log does not need (and probably should not be) to be a verbatim copy of the description in the bug.

Ah, that makes sense to me now, thanks for the explanation. Fixed.
