When calling variadic functions, NULL must be explicitly cast to a
desired type.
This is noted in the exec(3) manpage.
The call in newgrp.c was changed for consistency.

The recent change in code improves main-pool on error, but we need
to kill child process if it still running to avoid hang up in next
waitpid().

Permanently turn off current stdin ECHO when it is a terminal and enable setting slave ECHO instead.
Fix other minor typos, update documentation.
[kzak@redhat.com: - remove irrelevant changes
- keep --echo argument unchanged]

It some cases it makes sense to disable ECHO flag also when script
used in pipe. This new option allows to keep full control in user's
hands.

For tools like su(1) is ECHO flag unexpected for use-case like
echo 'date' | su - user
but script(1) need the echo to keep input recorded.
The patch also return execlp() use to script(1) code.

It's necessary to create signal-fd before fork() to get SIGCHLD,
because child could be faster than our code.

Now the code is duplicate on many places, but all we usually need is to
remember child status. It seems good enough to have very simple
callback child_die() to inform application about a change.
The patch also add PID to all signal related callbacks.

This patch consolidate pseudo-terminal stuff in util-linux. From now
there is only one implementation used in su(1) --pty, scriptlive(1)
and script(1).
The new stuff is based on the original script(1) -- it means poll()
and signalfd() based.
Note that script(1) code does not provide fallback for systems/libc
where is no openpty().

The new header/info lines in log uses 0, but it's unexpected by
scriptreplay as there was always number formatted by %f.
Signed-off-by: Karel Zak <kzak@redhat.com>
The old good scriptreplay(1) just display your recorded session, the
scriptlive(1) uses stdin typescript (from new script(1)) to execute
your commands again.

* add internal support for multiple log files
* add support for new timing file format (default is old format)
Signed-off-by: Karel Zak <kzak@redhat.com>
* allow to use --log-in <infile> and --log-out <outfile> in the same time
* add --log-io <file> to log stdout and stdin to the one log file
* introduce a new timing file format with entry type identifirs
I <delay> <size> : info about input stream
O <delay> <size> : info about output stream
in the next commits it's possible to add 'S' for signals and 'H' for
extra (header) information.
* the new file format is optional and enabled only if multiple streams
logging is requested.

Let's allow to log input independently on output. So it's possible to
script --log-in infile : logs only input
script --log-out outfile : logs only output
script --log-out outfile --log-in infile : logs both to separated files

The current -t[=<file>] is pretty messy due to optional <file>
argument; and default is to output to stderr. The default output to
stderr is very unusual semantic. This path makes the old -t
deprecated.
The new option -T, --log-timing requires the file name.

This commit does not add any new feature. It just prepare code for
future extensions only.
* introduce two new structs: script_stream and script_log
* define two streams: 'stdout' and 'stdin'
* allow associate log files (type script or timing file) with the stream
* support more log file formats

The current signalfd handler cares on CLD_EXITED only. It's pretty
insufficient as there is more situations (and codes) when child no
more running.

This patch introduces [...] to store extra information about terminal
to the typescript header. For example:
Script started on 2018-05-14 12:52:32+02:00 [TERM="xterm-256color" TTY="/dev/pts/3" COLS="190" LINES="53"]
or
Script started on 2018-05-14 12:54:01+02:00 [<not executed on terminal>]
if stdout is not terminal.

* always save "done" timestamp to typescript (use done() for this)
* use FORMAT_TIMESTAMP_MAX as buffer size
Signed-off-by: Karel Zak <kzak@redhat.com>
When script is used on a host with a relatively small free disk space, it
is sometimes desirable to limit the size of the captured output. This
can now be enforced with the --output-limit option.
The --output-limit option lets the user specify a maximum size. The program
uses the size parsing from strutils and thus supports the usual
multiplicative suffixes (kiB, KB, MiB, MB, etc.). After the specified
number of bytes have been written to the output file, the script program
will terminate the child process.
Due to buffering, the size of the output file might exceed the specified
limit. This limit also does not include the start and done messages.
The race test was throwing an error dur to a variable being "" in some cases.
Quoting the variable in the equal test took care of that test.
[kzak@redhat.com: - use done() to stop script
- count also timing file
- remove unnamed member initialization in ctl struct
- add to bash-completion]
