    • add lua binding for the lxc API · f080ffd7
      Dwight Engen authored 
      The lua binding is based closely on the python binding. Also included are
a test program for excercising the binding, and an lxc-top utility for
showing statistics on running containers.

    • setup_mount_entries: ignore mount failure if 'optional' · 68c152ef
      Serge Hallyn authored 
      If 'optional' is in the mount options, then avoid failure in
mount().

Experiments suggest we could just do this checking data at
mount_entry(), but that feels less proper than using
hasmntopt() against the mntent.

    • use a default per-container logfile · 5e1e7aaf
      Serge Hallyn authored 
      Until now, if a lxc-* (i.e. lxc-start) command did not specify a logfile
(with -o logfile), the default was effectively 'none'.  With this patch,
the default becomes a per-container log file.

If a container config file specifies 'lxc.logfile', that will override
the default.  If a '-o logfile' argument is specifed at lxc-start,
then that will override both the default and the configuration file
entry.  Finally, '-o none' can be used to avoid having a logfile at
all (in other words, the previous default), and that will override
a lxc.logfile entry in the container configuration file.

If the user does not have rights to open the default, then 'none' will
be used.  However, in that case an error will show up on console.  (We
can work on removing that if it annoys people, but I think it is
helpful, at least while we're still ironing this set out)  If the user
or container configuration file specified a logfile, and the user does
not have rights to open the default, then the action will fail.

One slight "mis-behavior" which I have not fixed (and may not fix) is
that if a lxc.logfile is specified, the default logfile will still
get created before we read the configuration file to find out there
is a lxc.logfile entry.

changelog:  Jan 24:

 add --enable-configpath-log configure option

 When we log to /var/lib/lxc/$container/$container.log, several things
 need to be done differently than when we log into /var/log/lxc (for
 instance).  So give it a configure option so we know what to do

 When the user specifies a logfile, we bail if we can't open it.  But
 when opening the default logfile, the user may not have rights to
 open it, so in that case ignore it and continue as if using 'none'.

 When using /var/lib/lxc/$c/$c.log, we use $LOGPATH/$name/$name.log.
 Otherwise, we use $LOGPATH/$name.log.

 When using /var/lib/lxc/$c/$c.log, don't try to create the log path
 /var/lib/lxc/$c.  It can only not exist if the container doesn't
 exist.  We don't want to create the directory in that case.  When
 using /var/log/lxc, then we do want to create the path if it does
 not exist.

    • MAKEDEV call, add autodev hooks, add environment variables for hook scripts. · f7bee6c6
      Michael H. Warfield authored 
      Ok...  Here's the patch again.  Since Serge is removing the loglevel
structure member, this patch no longer references that element.

From the original description:

1) Removes run_makedev() and the call to it from conf.c per discussion.

2) Adds an lxc.hook.autodev hook.

Note: This hook is very close (one routine level abstracted) from where
the run_makedev was called.  Anyone really rrreeeaaalllyyy needing
MAKEDEV can add it in with a small shim script to do whatever they want
under whatever distro they're using, so no functionality is lost there.

3) Added a number of environment variables for all the hook scripts to
reference to assist in execution.  Things like LXC_ROOTFS_MOUNT could be
very useful but others were added as well.  Room for more if anyone has
an itch.  All in one spot in lxc_start.c.

4) clearenv and putenv( "container=lxc" ) calls were moved to just after
the "start" hook in the container just prior to actually firing up the
container so we could use environment variables prior to that and have
them flushed them before firing up init.  Nice side effect is that you
can define environment variables and then call lxc-start and have them
show up in those hooks scripts.

5) I actually DID update the man page for lxc.conf!  I guess I lied when
I said I wouldn't get that done.

[... and ...]

I added the rcfile to the lxc_conf structure as suggested and moved the
setenv bundle from lxc-start.c over to start.c just prior to calling
run_lxc_hooks for the pre-start hook.

    • remove logfile and loglevel from struct lxc_conf · 9ea87d5d
      Serge Hallyn authored 
      The options are still supported in the lxc configuration file.
However they are stored only in local variables in src/lxc/log.c,
which can be read using two new functions:
	int lxc_log_get_level(void);
	const char *lxc_log_get_file(void);

Changelog: jan 14:
 have lxc_log_init use lxc_log_set_file(), have lxc_log_set_file() take
 a const char *, and have it keep its own strdup'd copy of the filename.
