No thanks.

I suspect this change is taking us in a wrong direction.  People
grep for function and struct declarations in <*.h> files and expect
to find the associated comments.

What is wrong here and what should i do to make it correct.

Hi Skrab,

I suspect that Junio's concern is that it appears the tool you're using
to auto-generate these .h files moves the comments away from the
declaration and into the header.

I imagine that such a change would be improved if:

  - You kept the comment attached to the function declaration (and
    ensured that it was present in the header file).

  - And we dropped the "this file is auto-generated by ..." comment,
    since I don't imagine that folks will be interested in adding a new
    tool to the development toolchain.

Thanks.

Almost everything in what the patch is wrong.

 * It creates <abspath.h> as a tracked file, but has a funny comment
   with control-G in it that says "do not edit"

 * It is entirely unclear how the contents of <abspath.h> is meant
   to evolve, if the contributors are forbidden to edit it, and
   without any instruction how to update it.

 * The new <abspath.h> lost all function comments, grouping by
   category, etc. that were in the original <cache.h>.

 * There is an "#undef INTERFACE" that has no use to us, those who
   develop Git, for no clearly explained reason.

 * The proposed log message says what it did, but it does not even
   try to justify why it is a good idea to do so.

 * There is no need to create a new <abspath.h> in the first place.
   If we were in an alternate world where we did not have
   <abspath.c>, it may be reasonable to add <abspath.h> along with
   it, instead of adding declarations for new functions and types in
   <cache.h>.  But the difference falls into "once it is in, it is
   not worth the patch churn to change it" category.

The easiest way to make it correct is to drop it, I guess.

Thanks.
