# [PATCH] git-format-patch: add --output-directory long option again 4 messages from 2006-06-06 to 2006-06-06. Participants: Dennis Stosberg, Johannes Schindelin, Junio C Hamano. Thread: https://gitlist.dev/t/4409 ## Dennis Stosberg, 2006-06-06 14:19 Subject: [PATCH] git-format-patch: add --output-directory long option again Message-ID: <20060606141946.G59b8a1fd@leonov.stosberg.net> URL: https://gitlist.dev/e/20060606141946.G59b8a1fd%40leonov.stosberg.net ``` Additionally this fixes two minor issues: (1) git-format-patch left an empty directory behind if an invalid option was given on the command line. (2) mkdir() was called with a NULL argument (argv[argc]), if -o was the last option on the command line.

How about this instead? -- >8 -- [PATCH] git-format-patch: add --output-directory long option again Additionally notices and complains to an -o option without directory or a duplicated -o option, -o and --stdout given together. Also delays the creation of directory until all arguments are parsed, so that the command does not leave an empty directory behind when it exits after seeing an unrelated invalid option.

Sorry. My version compiled and ran cleanly, but I was blinded by my goal: I wanted the directory to be _not_ created and checked that, but I didn't make sure, that the directory really existed in the other case, since Git didn't produce an error. > How about this instead? > [...] > + if (output_directory) { > + if (use_stdout) > + die("standard output, or directory, which one?"); Looks good. This piece changes behaviour; it no longer matches the docs.
