Subject: [PATCHv3 8/9] checkout-index: Fix negations of even numbers of -n
Date: Sat, 3 Aug 2013 13:51:25 +0200 [thread overview]
Message-ID: <1375530686-2309-9-git-send-email-stefanbeller@googlemail.com> (raw)
In-Reply-To: <1375530686-2309-1-git-send-email-stefanbeller@googlemail.com>
The --no-create was parsed with OPT_BOOLEAN, which has a counting up
logic implemented. Since b04ba2bb (parse-options: deprecate OPT_BOOLEAN,
2011-09-27) the OPT_BOOLEAN is deprecated and is only a define:
/* Deprecated synonym */
#define OPTION_BOOLEAN OPTION_COUNTUP
However the variable not_new, which can be counted up by giving
--no-create multiple times, is used to set a bit in the struct checkout
bitfield (defined in cache.h:969, declared at builtin/checkout-index.c:19):
state.not_new = not_new;
When assigning a value other than 0 or 1 to a bit, all leading digits but
the last are ignored and only the last bit is used for setting the bit
variable.
Hence the following:
# in git.git:
$ git status
# working directory clean
rm COPYING
$ git status
# deleted: COPYING
$ git checkout-index -a -n
$ git status
# deleted: COPYING
# which is expected as we're telling git to not restore or create
# files, however:
$ git checkout-index -a -n -n
$ git status
# working directory clean, COPYING is restored again!
# That's the bug, we're fixing here.
By restraining the variable not_new to a value being definitely 0 or 1
by the macro OPT_BOOL the bug is fixed.
