Looks good to me now!

Thanks for both.

Weird. But you're probably right. Darn that 70's syntax. :-)

>> The copy of zh_XX is done in GensrcCorba, but the original file is created in CompileCorba. Does that really work? On a clean compile? Looks incorrect to me.
> The original file is in the source tree and I generate the zh_HK version by copying it to gensrc. Then in CompileCorba all the properties files exist as source files for the clean. I could have opted to copy the cleaned file in CompileCorba instead but I thought this was easier. I realize it's not consistent with how it's done in the jdk repo though.

Aha, I see now that you copy the properties file. I misread it as the java file. Ok.

Fair enough. There's still plenty left to cleanup for everyone. :) 

>> I'm not clear about the handling of zh_XX files here. First, you have an install-file %-pattern rule. Then you have an COPY_EXTRA addition. Are both needed? Why? Is it to create dependencies on the copied files?
> If you look in CompileJavaClasses.gmk, from which CopyIntoClasses.gmk is included, COPY_EXTRA is simply added to the dependency list at the end, so yes, that's what it is. A pattern rule in itself will not be very useful without some targets being depended on.

Right. I got it confused with the COPY and CLEAN variables being passed into the macro call.

>> Have you confirmed that the CLEAN_FILES list does not intersect with the properties files listed for compilation?

>> * In GensrcProperties:
>> There was a comment on us not handling removed properties correctly in incremental builds. That's still applicable, right?
> Where was this comment? We don't handle removed files well in most cases since that's not how make normally works. Automatically removing files in the output requires keeping books on which files generated what and to have a separate remove step in the makefile. Fredrik wrote this for jar file generation so it probably works when removing java files today. If removing a C file, it will not be linked, but the object file will still be around.
>> The zh_XX code (again): there are two pattern rules with the same target. Do we alternatively copy generated and pre-generated files from src/share/classes? What if they clash? (I'm no good at how make resolved pattern rules.) If the zh_TW file is checked in and not generated, shouldn't we check in a copy as the zh_HK file as well?
> There are some pre-generated java properties bundles in the source tree yes. I chose not to change anything regarding them. As for clashing, the first rule that matches will be used. In this case I very much doubt we will ever see a clash.
>> In convert_tw_to_hk, what kind of sed expression is that? Never seen one of those; what does it do?
> I'm pretty sure it was just picked up from the old build. My understanding is that it searches for a line matching the regexp "class" and if found does a single search replace for "_zh_TW" to "_zh_HK" on that line.

Aha, it's a combined /class/ and s/zh_TW/zh_HK/. I see. Thought it was some fancy four-way operator.
