Eric Blake	cc5e2a849c	command: improve behavior on no output ... Guarantee that outbuf/errbuf are allocated on success, even if to the empty string. Caller always has to free the result, and empty output check requires checking if *outbuf=='\0'. Makes the API easier to use safely. Failure is best effort allocation (some paths, like out-of-memory, cannot allocate a buffer, but most do), so caller must free buffer on failure. * docs/internals/command.html.in: Update documentation. * src/util/command.c (virCommandSetOutputBuffer) (virCommandSetErrorBuffer, virCommandProcessIO) Guarantee empty string on no output. * tests/commandtest.c (test17): New test.	2010-12-07 15:35:30 -07:00

(virCommandRun): Reject execution with user-specified fds not visiting a regular file.	2010-12-07 15:30:24 -07:00
