f6b68cbd3d Add some extra cancel_func protection to QEMUInstall
In livemedia-creator's usage of this it can never pass in None, but if
someone were to import the library and use it, it would crash with
NoneType. So add the extra checks to make sure cancel_func isn't None,
just in case.

cf13e9fd32 installer: make sure cancel_func has a value (#612)
When using LMC to virt-install a system to an image, cancel_func is not
provided in run_creator, causing a TypeError (NoneType object is not
callable).

6f90f18e31 Remove duplicate repositories from the sources list
In some cases when the host has, for whatever reason, multiple copies of
the same repo listed the build may fail with an error about running out
of space.

So this commit removes duplicate entries after the host's repos have been
loaded. It also adjusts some of the test repos to use different
temporary repo names for the tests.

98d56fba67 lorax: Move default tmp dir to /var/tmp/lorax
If systemd's tmpfiles.d timer is executed while lorax is running it will
remove any files and directories older than 30 days. This is what has
been causing the occasional error where /proc/ would seem to vanish
during the install.

Upstream has proposed this solution, https://github.com/systemd/systemd/pull/11482
but until that is released we need a work-around to protect the lorax
files.

This commit does several things:

* Move the default tmpdir from /var/tmp/ to /var/tmp/lorax/
* Add a lorax.conf tmpfiles.d file that prevents systemd-tmpfiles from
  removing anything under /var/tmp/lorax/
* Add an exit handler to lorax so that temporary directories are removed on
  exit or on a python traceback.
* Use flock to lock access to the tempdir while lorax is running.
* Remove any unlocked tempdirs named /var/tmp/lorax/lorax.* at startup

Note that the exit handler will not remove the tempdir if lorax is
killed with a signal -- those are being caught by dnf and prevent the
exit handler from running.

systemd-tmpfiles cannot clean up the tempdirs at boot time because they
contain files labeled as shadow_t, so we have to remove those when lorax
runs. It uses the flock to prevent removing any directories created by
parallel instances of lorax and only removes ones that are unlocked.
Worst case they will be around until the first run of lorax after a
reboot.

If you want to keep the working directory around for debugging purposes
use --workdir /var/tmp/lorax/my-workdir and it won't be removed by
lorax.

2953328fd0 Don't exclude /dev from the setfiles in novirt_install
After a novirt disk image install, we run `setfiles` in the
install root to ensure some SELinux contexts are correct. /dev
is currently excluded from this run. However, as reported and
discussed in https://bugzilla.redhat.com/show_bug.cgi?id=1663040
it seems that with a recent systemd change, startup of many
services will fail if /dev itself is incorrectly labelled, and
in current Rawhide live images, it *is* incorrectly labelled.
Including `/dev` in this setfiles command appears to resolve the
problem in my testing.

bc574e2e2f Allow customizations to be specified as a toml list
Support both

  [customizations]
  hostname = "whatever"

and

  [[customizations]]
  hostname = "whatever"

in the blueprint data. The [[ syntax matches the other customization
directives (user, group, sshkey), and as such it's easy to accidentally
use it for the hostname without even realizing it's specifying something
different.

Add some tests for converting customizations to kickstarts.

e3e892ea43 lorax-composer: Cancel running Anaconda process
It ends up that this isn't as easy as you'd think. Anaconda sets up some
signal handlers to handle cleanly exiting, but they are not being run
when sent a TERM after package installation has started. I think DNF
resets them causing it to get ignored.

When the cancel is sent it can take several minutes for it to have an
effect. In my testing it usually takes around 2 minutes for anaconda to
notice and exit.

This sends a TERM to the process and then waits for it to exit. When it
returns it then removed any device-mapper devices that were setup for
image installations, removes any hanging loop devices.

It then kills off any process with pyanaconda. in the cmdline, and
anaconda-bus.conf (because anaconda starts a bunch of helpers and if it
doesn't shut down cleanly they remain running).

41658811dc Add cancel_func to virt and novirt_install functions
In addition to monitoring the logs for errors, call a function (or
functions) that tell it to cancel the anaconda process and cleanup.

Also check for a cancel after creating the squashfs image for live-iso
since that's a long running process.

This required adding a new argument to a number of existing functions,
passing it down to QEMUInstall and novirt_install where the function is
called.

ed611933cb lorax-composer: Handle packages with multiple builds
When the repository has multiple arches, eg. i686 and x86_64, it should
add a new entry to the project's builds list, not create a new project
in the list.

This handles that by adding a modified insort_left function and
examining the packages returned from dnf to make sure they aren't
already listed in the results. It also handles adding them in sorted
order so that no further sorting needs to be done on the results.

dfb2b962b3 lorax-composer: Check the queue and results at startup
If the system ran out of space, or was rebooted unexpectedly, the state
of the queue symlinks, or the results STATUS files may be inconsistent.
This checks them and:
 * Removes broken symlinks from queue/new and queue/run
 * Removes symlinks from run and sets the build to FAILED
 * Sets builds w/o a STATUS to FAILED
 * Sets builds with STATUS of RUNNING to FAILED
 * Creates missing queue/new symlinks to results with STATUS of WAITING

So, any builds that were running during the reboot will be FAILED, and
any that were waiting to be started will be started upon rebooting.

a5c5cb457e Add --no-system-repos to lorax-composer
Running lorax-composer --no-system-repos will prevent it from copying
the dnf repositories from /etc/yum.repos.d/ into the lorax-composer repo
directory. It will *only* use repositories setup using the sources api
or written to /var/lib/lorax/composer/repos.d/

If lorax-composer has previously been run without this switch the system
repos will need to be removed from the composer/repos.d/ directory. It
would also be a good idea to remove the cached metadata in
/var/tmp/composer/

fb1dfc9488 Report an error if the blueprint doesn't exist
composer-cli uses TOML for 'blueprints save' which was returning an
empty 200 response if the blueprint didn't exist. Change this to return
a standard 400 error response if the blueprint doesn't exist.

composer-cli is already setup to handle receiving json when an error is
returned so just the toml API response for `blueprints/save` needed to
be changed.

13e6a68154 Always update repo metadata when building an image
When the kickstart is handed off to Anaconda for building it will
download its own copy of the metadata and re-run the depsolve. So if the
dnf cache isn't current there will be a mismatch and the build will
fail to find some of the versions in final-kickstart.ks

This adds a new context to DNFLock, .lock_check, that will force a check
of the metadata. It also implements its own timeout and forces a
refresh of the metadata when that expires because the dnf expiration
doesn't always work as expected.
