[PATCH 00/10] object-file API: pass object enums, tidy up streaming interface

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



This is intended to help along the "unpack large blobs in stream"
series that Han Xin has been submitting. The v9 of it is available
at[1], but not currently picked up by Junio.

This changes those parts of the object-file.c API that took a "const
char *" type to take an "enum object_type" instead. We had a lot of
places that would convert back & forth between the two for no good
reason. We're still left with the "literally" interface for "git
hash-object --literally", but it's now a tiny part of the API that's
sidelined.

This also has various small API cleanups, such as returning "void" in
a case where no caller did (or should) use a return value in the case
of hash_object_file().

We then introduce the format_object_header() helper, part of that was
in Han Xin's version, but we had various other in-tree users that
could use it (which I found later, after my initial RFC patch).

We can then split up the two classes of API users of
check_object_signature() to use two different functions, which suits
their uses much better. Half of them were making use of a very early
return.

Ævar Arnfjörð Bjarmason (10):
  object-file.c: split up declaration of unrelated variables
  object-file API: return "void", not "int" from hash_object_file()
  object-file API: add a format_object_header() function
  object-file API: have write_object_file() take "enum object_type"
  object-file API: provide a hash_object_file_oideq()
  object-file API: replace some use of check_object_signature()
  object-file API: have hash_object_file() take "enum object_type"
  object-file API: replace check_object_signature() with stream_*
  object-file.c: add a literal version of write_object_file_prepare()
  object-file API: pass an enum to read_object_with_reference()
