* sponge: Fix bug in -a mode that doubled original content of fileJoey Hess2019-01-091-1/+1
| | | | | | | | Occurred when the temp file is located on a different filesystem. It seems that append mode was put in on that file open without realizing the consequences of it. Bug has been present since the first -a patch. This commit was sponsored by Peter on Patreon.
* make -a create the file atomicallyJoey Hess2015-01-191-13/+25
| | | | | Ie, copy existing file content to temp file, then append sponged input, then rename over.

* sponge: add append option '-a' (Closes: #623197)Nicolas Schier2015-01-191-2/+10
| | | | | | | | With this patch, option '-a' is introduced to append to the output file instead of doing backup and recreation. Original-by: Michael Stummvoll <michael@stummi.org> Signed-off-by: Nicolas Schier <nicolas@hjem.rpa.no>

* put back optimisation when outputting to stdoutJoey Hess2010-09-131-9/+21
| | | | | | Recent changes made it always write to the tmp file, even if it was just going to send a small quantity of data to stdout. Bring back optimisation to avoid temp file in that case.

* sponge: Correct bad use of fread that caused a trailing quantity of soaked ↵Joey Hess2010-09-021-4/+5
| | | | | | | | | data to be silently discarded when a temp file was used and sponge output to stdout. Closes: #595220 This bug was sorta introduced by 6f31909ff74c064ea0b5126219b3e8f7b8826bee. Actually, the buggy fread was there before also, and would have happened on quantities of data not evenly divisible by 8.

* more fixes to tempfile writebackJoey Hess2008-04-111-21/+33
| | | | | | Avoid overwriting symlinks with the temp file. When renaming the temp file, restore the original file's permissions after.
* set umask before calling mkstempJoey Hess2008-04-111-1/+3
| | | | | | This is a POSIX portability thing. Restore the original umask after.
* fix two bugs writing the output fileJoey Hess2008-04-111-15/+18
| | | | | | | | If the output file doesn't exist, the new code was buggy and did not create it. Also, the rename could fail (ie, /tmp on another filesystem). So if it falls fall back to the manual copy.
* move code into a functionJoey Hess2008-04-111-14/+24
|
* fix edge casesJoey Hess2008-04-111-5/+10
| | | | | | | | | If a file an exact multiple of the max buffer size were sponged, it would fail at the end due to trying to write 0 remaining bytes from the buffer to the temp file. A similar bug occurred if sponge's input was empty. Amazing how such a seemingly simple thing can get so tricky.. Also added check for read error from the temp file, just in case.
