Re: Problem with S_IFGITLINK

2011/8/24 Adam Kłobukowski <adamklobukowski@gmail.com>:

Git stores mode in the index (struct cache_entry#ce_mode, cache.h) and in tree objects (see tree-walk.c). Basically you define a new set of S_IS* and S_IF* macros and use them instead of standard ones. Translations from struct stat#st_mode will be needed, I think ce_mode_from_stat() does that job.

So:
 - read index and checkout: entry.c
 - read and update index: read-cache.c
 - read tree objects: tree-walk.c
 - write tree objects: cache-tree.c
 - anywhere that checks struct cache_entry#ce_mode needs to convert to
use the new defines

Another way, less changes, is redefine S_IS* and S_IF* and ignore system values. Then make wrapper for stat() and lstat(), convert system values to git values. You can put these wrappers in compat directory. See git-compat-util.h, mingw port for example already redefine these functions for Windows platform.
