Revision ec0603e13c4e33c3a1501fe16f576db9aff1701a authored by Junio C Hamano on 12 July 2007, 08:04:16 UTC, committed by Junio C Hamano on 12 July 2007, 09:22:53 UTC
Earlier in 16a4c61, we taught "read-tree -m -u" not to be confused when switching from a branch that has a path frotz/filfre to another branch that has a symlink frotz that points at xyzzy/ directory. The fix was incomplete in that it was still confused when coming back (i.e. switching from a branch with frotz -> xyzzy/ to another branch with frotz/filfre). This fix is rather expensive in that for a path that is created we would need to see if any of the leading component of that path exists as a symbolic link in the filesystem (in which case, we know that path itself does not exist, and the fact we already decided to check it out tells us that in the index we already know that symbolic link is going away as there is no D/F conflict).

/* Help to copy the thing properly quoted for the shell safety.
* any single quote is replaced with '\'', any exclamation point
* is replaced with '\!', and the whole thing is enclosed in a
* single quote pair.
*
* For example, if you are passing the result to system() as an
* argument:
*
* sprintf(cmd, "foobar %s %s", sq_quote(arg0), sq_quote(arg1))
*
* would be appropriate. If the system() is going to call ssh to
* run the command on the other side:
*
* sprintf(cmd, "git-diff-tree %s %s", sq_quote(arg0), sq_quote(arg1));
* sprintf(rcmd, "ssh %s %s", sq_quote(host), sq_quote(cmd));
*
* Note that the above examples leak memory! Remember to free result from
* sq_quote() in a real application.
*
* sq_quote_buf() writes to an existing buffer of specified size; it
* will return the number of characters that would have been written
* excluding the final null regardless of the buffer size.
