By the way if you have already sent some of the patches in this series
(and if they haven't changed much since when you sent them), it's a
good idea to use V2 or V3, V4, etc, so we can easily refer to each of
the versions you sent. (See the `-v` option of `git format-patch`.)

Change from last version:

 1. Declare buf_size in if (atom_type == ATOM_RAW) block.
 2. Modify the code style of the test.
 3. Delete "use_textconv" and "use_filter" flag. Instead, add member

s/flag/flags/

    cat_file_cmdmode to struct ref_array_item.
 4. Add function reject_atom() to enhance the readability of the code.
 5. Create p1006-cat-file.sh for performance regression testing.
 6. Use a "fast path" to output object data to reduce the performance
    degradation of cat-file --batch with the suggest of Ævar Arnfjörð
    Bjarmason.

Maybe:

Arnfjörð Bjarmason/

or:

s/with the suggest of Ævar Arnfjörð Bjarmason/according to Ævar
Arnfjörð Bjarmason's suggestion/

ZheNing Hu (19):
  cat-file: handle trivial --batch format with --batch-all-objects
  cat-file: merge two block into one

It's a bit strange that the above 2 don't have [GSOC] while the others
below have it.

  [GSOC] ref-filter: add obj-type check in grab contents
  [GSOC] ref-filter: add %(raw) atom
  [GSOC] ref-filter: --format=%(raw) re-support --perl
  [GSOC] ref-filter: use non-const ref_format in *_atom_parser()
  [GSOC] ref-filter: add %(rest) atom
  [GSOC] ref-filter: pass get_object() return value to their callers
  [GSOC] ref-filter: introduce free_ref_array_item_value() function
  [GSOC] ref-filter: introduce reject_atom()
  [GSOC] ref-filter: modify the error message and value in get_object
  [GSOC] cat-file: add has_object_file() check
  [GSOC] cat-file: change batch_objects parameter name
  [GSOC] cat-file: reuse ref-filter logic
  [GSOC] cat-file: reuse err buf in batch_object_write()
  [GSOC] cat-file: re-implement --textconv, --filters options
  [GSOC] ref-filter: remove grab_oid() function
  [GSOC] cat-file: create p1006-cat-file.sh

Maybe you could add the new perf test earlier in the series so that we
could see how performance changes when ref-filter logic is reused in
cat-file earlier in the series.
