Hi, Junio and Stolee
I was looking further at this code and noticed that the conditions
under which we fstat() (or lstat()) an entry are slightly different
throughout entry.c:
- In write_entry()'s footer, we call lstat() iff stat->refresh_cache.
- In write_entry()'s `write_file_entry` label, we call fstat_output()
when !to_tempfile.
- In streaming_write_entry() we call fstat_output() without checking
if !to_tempfile.
- And, finally, in fstat_output() itself, we check
`state->refresh_cache && !state->base_dir_len`.
I understand we always check state->refresh_cache to avoid getting
stat information we won't really need later, as we are not updating
the index. But why do we check !to_tempfile and !state->base_dir_len?
Doesn't writing to a tempfile or using a checkout prefix already imply
!state->refresh_cache?
Thanks,
Matheus
