Joseph Myers a1f6a9abbe Make build-many-glibcs.py support running as a bot.
This patch makes build-many-glibcs.py support a "bot" action, for
repeatedly running a checkout and build cycle.

Two new configuration variables are used in bot-config.json.  "delay"
indicates the time to sleep after each bot-cycle round (regardless of
whether that round actually ran any builds); "run" is a boolean, which
is false if the bot should just exit (the point of this is that you
can edit bot-config.json to set this to false to cause a running bot
to exit cleanly between builds) and true if the bot should run.  The
bot does not exit if the bot-cycle process exits with error status
(that can occur when sourceware's load limiting means anonymous
version control access fails, for example), just sleeps until it's
time to try again.

The script is changed to flush stdout before running a subprocess in
bot-cycle, so that when output is redirected (as expected for a bot)
the status messages from bot-cycle appear in their proper position in
its redirected output relative to the output from the subprocesses
run, and to copy the logs directory before running builds in bot-cycle
so that the logs from at least one complete build are always available
for looking at how something failed, even while the next build is
running.

	* scripts/build-many-glibcs.py: Add bot to usage message.  Import
	time module.
	(Context.__init__): Initialize self.logsdir_old.
	(Context.run_builds): Handle bot action.
	(Context.bot_cycle): Copy logs directory before running builds.
	(Context.bot_run_self): Take argument for whether to check
	subprocess result.  Flush stdout before running subprocess.
	(Context.bot): New function.
	(get_parser): Allow bot action.

This directory contains the sources of the GNU C Library.
See the file "version.h" for what release version you have.

The GNU C Library is the standard system C library for all GNU systems,
and is an important part of what makes up a GNU system.  It provides the
system API for all programs written in C and C-compatible languages such
as C++ and Objective C; the runtime facilities of other programming
languages use the C library to access the underlying operating system.

In GNU/Linux systems, the C library works with the Linux kernel to
implement the operating system behavior seen by user applications.
In GNU/Hurd systems, it works with a microkernel and Hurd servers.

The GNU C Library implements much of the POSIX.1 functionality in the
GNU/Hurd system, using configurations i[4567]86-*-gnu.  The current
GNU/Hurd support requires out-of-tree patches that will eventually be
incorporated into an official GNU C Library release.

When working with Linux kernels, this version of the GNU C Library
requires Linux kernel version 3.2 or later on all architectures except
i[4567]86 and x86_64, where Linux kernel version 2.6.32 or later
suffices.

Also note that the shared version of the libgcc_s library must be
installed for the pthread library to work correctly.

The GNU C Library supports these configurations for using Linux kernels:

	aarch64*-*-linux-gnu
	alpha*-*-linux-gnu
	arm-*-linux-gnueabi
	hppa-*-linux-gnu	Not currently functional without patches.
	i[4567]86-*-linux-gnu
	x86_64-*-linux-gnu	Can build either x86_64 or x32
	ia64-*-linux-gnu
	m68k-*-linux-gnu
	microblaze*-*-linux-gnu
	mips-*-linux-gnu
	mips64-*-linux-gnu
	powerpc-*-linux-gnu	Hardware or software floating point, BE only.
	powerpc64*-*-linux-gnu	Big-endian and little-endian.
	s390-*-linux-gnu
	s390x-*-linux-gnu
	sh[34]-*-linux-gnu
	sparc*-*-linux-gnu
	sparc64*-*-linux-gnu
	tilegx-*-linux-gnu
	tilepro-*-linux-gnu

If you are interested in doing a port, please contact the glibc
maintainers; see http://www.gnu.org/software/libc/ for more
information.

See the file INSTALL to find out how to configure, build, and install
the GNU C Library.  You might also consider reading the WWW pages for
the C library at http://www.gnu.org/software/libc/.

The GNU C Library is (almost) completely documented by the Texinfo manual
found in the `manual/' subdirectory.  The manual is still being updated
and contains some known errors and omissions; we regret that we do not
have the resources to work on the manual as much as we would like.  For
corrections to the manual, please file a bug in the `manual' component,
following the bug-reporting instructions below.  Please be sure to check
the manual in the current development sources to see if your problem has
already been corrected.

Please see http://www.gnu.org/software/libc/bugs.html for bug reporting
information.  We are now using the Bugzilla system to track all bug reports.
This web page gives detailed information on how to report bugs properly.

The GNU C Library is free software.  See the file COPYING.LIB for copying
conditions, and LICENSES for notices about a few contributions that require
these additional notices to be distributed.  License copyright years may be
listed using range notation, e.g., 1996-2015, indicating that every year in
the range, inclusive, is a copyrightable year that would otherwise be listed
individually.
