2008-07-30Fix merge name generation in "merge in C"Libravatar Junio C Hamano1-2/+2
When merging an early part of a branch, e.g. "git merge xyzzy~20", we were supposed to say "branch 'xyzzy' (early part)", but it incorrectly said "branch 'refs/heads/xy' (early part)" instead. The logic was supposed to first strip away "~20" part to make sure that what follows "~" is a non-zero posint, prefix it with "refs/heads/" and ask resolve_ref() if it is a ref. If it is, then we know xyzzy was a branch, and we can give the correct message. However, there were a few bugs. First of all, the logic to build this "true branch refname" did not count the characters correctly. At this point of the code, "len" is the number of trailing, non-name part of the given extended SHA-1 expression given by the user, i.e. number of bytes in "~20" in the above example. In addition, the message forgot to skip "refs/heads/" it prefixed from the output. Signed-off-by: Junio C Hamano <gitster@pobox.com>

2008-07-21builtin-merge: add missing structure initializationLibravatar Pierre Habouzit1-0/+1
The parameter that is eventually passed to read_directory() to scan the working tree should be properly initialized. Signed-off-by: Pierre Habouzit <madcoder@debian.org> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2008-07-21builtin-merge: give a proper error message for invalid strategies in configLibravatar Miklos Vajna1-25/+12
'git merge -s foobar' diagnosed invalid "foobar" strategy and errored out with a message, but foobar in pull.twohead or pull.octopus was just silently ignored. This makes invalid strategy both on the command line and in the configuration file to trigger the same error.

2008-07-20builtin-merge.c: Fix option parsingLibravatar Michele Ballabio1-2/+3
Now "git merge -m" needs a message, and errors out with the usage text if none is given. This way, t7600-merge.sh is fixed. Signed-off-by: Michele Ballabio <barra_cuda@katamail.com> Acked-by: Miklos Vajna <vmiklos@frugalware.org> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2008-07-20Teach 'git merge' that some merge strategies no longer existLibravatar Miklos Vajna1-2/+0
'recur' co-existed with 'recursive' when rewriting it in C, but it no longer available. 'stupid' was also recently removed. "git merge -s confused origin" still includes them in the list of available merge strategies.
