one can now add an option "offset" to the config map. Positive offsets
are interpreted to be from the beginning of the file, negative from the
end of the file (-1 is end of file).
Only works for raw reader in streaming or manual mode. Does not work
with executables.
Addresses BIT-985
- Generally increased the time allowed before they timeout.
- For tests w/ a clear termination condition (most of them), made
timeouts result in a test failure.
- Seemed to be a race in some cases between tests generating output and
the input reader stream getting removed/closed, so moved stream removal
closer to termination time, when all output should be available.
- Primarily working around an issue that occurs when threads
concurrently create pipes and fork a child process. See comment in
code...
- Other minor cleanup of the code: making sure the child process calls
_exit() versus exit(), limits itself to few select system calls before
the exec(), and closes more unused file descriptors.
- Do stream mode for commands done by exec module, it seems important
in some cases (e.g. ensure requested stdin is fully written).
- For cases where the raw input reader knows the child process has been
reaped, set the childpid member to a sentinel value to indicate such
so we don't later think we should kill it or wait on it anymore.
- More error checking on dup2/close calls. Set sentinel values when
closing ends of pipes to prevent double closing a fd.
- Signal flag not set when raw input reader's child exits as a result
of a signal. Left out a test for this -- might be portability issues
(e.g. Ubuntu seems to do things different regarding the exit code and
also is printing "Killed" to stderr where other platforms don't).
* send end_of_data event for all kind of streams
* send process_finished event containing exit code of child process for executed programs
* move raw-tests to separate directory
* expose name of input stream to readers
* better handling of some error cases in raw reader
* new force_kill option for raw reader which SIGKILLs progesses on exit
The ordering of events how they arrive in the main loop is a bit peculiar at the moment.
The process_finished event arrives in scriptland before all of the other events, even though
it should be sent last. I have not yet fully figured that out.
