It is only used by the copy-in and copy-out APIs. Unfortunately this made the command code very complex: it was almost impossible to redirect stderr to a file, and there were a lot of long-range dependencies through the file. It was also buggy:

Previously posted: https://www.redhat.com/archives/libguestfs/2017-October/msg00032.html This takes a completely different approach. It turns out that POSIX / the shell already defines a special exit code 127 for ‘command not found’. We can make a small adjustment to lib/command.c to return this exit code in that case. Then we just have to modify the db_dump code to test for this exit code. I

This is almost just refactoring, but I also set the memory limit to really 1 GB, and not 1×10⁹. --- src/info.c | 27 +++++++++++++++------------ 1 file changed, 15 insertions(+), 12 deletions(-) diff --git a/src/info.c b/src/info.c index d7f45f0..616ef50 100644 --- a/src/info.c +++ b/src/info.c @@ -56,6 +56,7 @@ static yajl_val get_json_output (guestfs_h *g, const char *filename); static char
