[PATCH 1/3] Change "refs/" references to symbolic constants

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

 



Changed repeated use of the same constants for the ref paths to be
symbolic constants.  I've defined them in refs.h

  refs/ is now PATH_REFS
  refs/heads/ is now PATH_REFS_HEADS
  refs/tags/ is now PATH_REFS_TAGS
  refs/remotes/ is now PATH_REFS_REMOTES

I've changed all references to them and made constants for the string
lengths as well.  This has clarified the code in some places; for
example:

 - len = strlen(refs[i]) + 11;
 + len = strlen(refs[i]) + STRLEN_PATH_REFS_TAGS + 1;

In this case 11 isn't STRLEN_PATH_REFS_HEADS, as it is in most other
cases, it's TAGS + 1.  With the change to symbolic constants it's much
clearer what is happening.
