Subject: Tempfile cleanup problem revisited: G_tempfile()
grass obtained from: CVS
grass binary for platform: Compiled from Sources
GRASS Version: latest CVS
Hi,
some of you may remember the thread about the GRASS tempfile problem:
http://grass.itc.it/pipermail/grass5/2002-April/002598.html
I have revisited the problem and done a draft check where G_tempfile() function
is used but the temp file not deleted later (using unlink()). This leads to left-over
files if GRASS is not left with "exit" (but simply the GRASS shell-window clicked
away) since $ETC/clean_temp won't be run in this case. In our networked GRASS
database I found 1GB leftover files.
My quick-and-dirty test has delivered:
find . -type f -name '*.c' -exec grep -l G_tempfile {} \;
find . -type f -name '*.c' -exec grep -l unlink {} \;
Diff'ed list of potential modules which call G_tempfile() but do not
use the unlink() function to delete the tempfile(s) later:
- example: r.drain

(slightly cleaned up list)
These modules have to be checked if the G_tempfile is properly
deleted on G_fatal_error() or successful module termination.
