Here it is. There actually weren't that many spots to clean up, as quite a few of them have a "twist" where they want to do something clever, like open the file and feed the descriptor to a sub-function, or open with funny things like O_EXCL. But still, the diffstat is pleasing: builtin/am.c | 25 +++++++---------- builtin/branch.c | 5 +--- builtin/config.c | 2 +- builtin/merge.c | 45 ++++-------------------------- cache.h | 17 ++++++++++-- wrapper.c | 52 ++++++++--------------------------- 6 files changed, 44 insertions(+), 102 deletions(-) and that even includes adding some function documentation. The most interesting thing is that I also found a real bug, albeit a fairly minor one. I floated that up to the front of the series. [1/8]: config: fix bogus fd check when setting up default config [2/8]: am: ignore return value of write_file() [3/8]: branch: use non-gentle write_file for branch description [4/8]: write_file: drop "gently" form [5/8]: write_file: use xopen [6/8]: write_file: add pointer+len variant [7/8]: write_file: add format attribute [8/8]: use write_file_buf where applicable -Peff -- To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
