Hi people,
I do not know if I hit that behavior before, but now it hit me big time:
if a commit moves a certain string from one place to another, "git log
-S<string>" does not pick up that commit. The code responsible for this
is in diffcore-pickaxe.c:
else if (!diff_unmodified_pair(p) &&
contains(p->one, needle, len, regexp) !=
contains(p->two, needle, len, regexp))
has_changes++;
Basically, the "contains()" method says how often the needle was found,
and pickaxe just assumes that a move of a string is not interesting
enough.
Now, this behavior is probably intended, as searching files is much
cheaper than generating the diffs between them, yet it is something you'll
have to keep in mind when using "-S".
Ciao,
Dscho
