From: Michael Haggerty Date: Mon, 10 Aug 2015 09:47:44 GMT Subject: [PATCH v2 09/16] register_tempfile(): new function to handle an existing temporary file Message-ID: <8f223a2e98b18137673fe5b02fdddf3d93404108.1439198011.git.mhagger@alum.mit.edu> In-Reply-To: Allow an existing file to be registered with the tempfile-handling infrastructure; in particular, arrange for it to be deleted on program exit. This can be used if the temporary file has to be created in a more complicated way than just open(). For example: * If the file itself needs to be created via the lockfile API * If it is not a regular file (e.g., a socket) Signed-off-by: Michael Haggerty --- tempfile.c | 8 ++++++++ tempfile.h | 8 ++++++++ 2 files changed, 16 insertions(+) diff --git a/tempfile.c b/tempfile.c index 0b5d8ce..0af7ebf 100644 --- a/tempfile.c +++ b/tempfile.c @@ -137,6 +137,14 @@ int create_tempfile(struct tempfile *tempfile, const char *path) return tempfile->fd; } +void register_tempfile(struct tempfile *tempfile, const char *path) +{ + prepare_tempfile_object(tempfile); + strbuf_add_absolute_path(&tempfile->filename, path); + tempfile->owner = getpid(); + tempfile->active = 1; +} + int mks_tempfile_sm(struct tempfile *tempfile, const char *template, int suffixlen, int mode) { diff --git a/tempfile.h b/tempfile.h index a30e12c..4219fe4 100644 --- a/tempfile.h +++ b/tempfile.h @@ -92,6 +92,14 @@ struct tempfile { */ extern int create_tempfile(struct tempfile *tempfile, const char *path); +/* + * Register an existing file as a tempfile, meaning that it will be + * deleted when the program exits.
