And in an intermediate version it returns a VectorString object which
isn't serializable by the json or toml modules.
So convert it to a list so that the type is consistent in the sources
code.
By default mkfs.mksdos choose volume id based on current time. If
SOURCE_DATE_EPOCH is set, use that instead.

The previous method worked, but wasn't exactly idiomatic. This is more
correct, and appears to work the same (templates depsolve, version globs
work, multiple repos work).
Note that this does use a private dnf attribute ._goal, but the word is
that this is going to become a public api soon, so yes it is there on
purpose.
Depending on how lorax-composer is run setting up an empty blueprints
directory can fail. So this moves checking/creation until after the
other directories are created and uses make_owned_dir to make sure
ownership is correct.
It needs to be root in order to set the ownership and permissions on the
directories that are under /var/lib/lorax/composer/
Refactor the directory creation into a utility function, and use a umask
of 0o006 to ensure that the parent directories created do not have o+rw
set on them (makedirs behavior is different between Python 3.6 and 3.7
so umask of 0 doesn't work consistently).
If a package is in multiple repos dnf may return more than 1 of them
when using best...glob so we pick the highest NEVRA one and install
that.

At the end of disk image installs, use fstrim on the generated filesystem to
discard any blocks that were allocated during the install and are now unused.
This will allow tools such as qemu-img to create images that do not include
deleted data.
For raw disk images that do not go through qemu-img, use fallocate --dig-holes
to create sparse holes in place of the unused blocks.
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.
`os.path.exists("/run/weldr/api.socket")` returns False for users which have no
access. This leads to composer printing that the file does not exist, which is
misleading.
Since it's no possible to distinguish the two cases, fix this problem by
combining them and showing a single error message.
Anaconda requires the root password to be set or locked, so if there
isn't anything setting it we write out 'rootpw --lock'
Also adds tests for this.

See https://bugzilla.redhat.com/show_bug.cgi?id=1595917 and
https://github.com/rpm-software-management/dnf/pull/1200 for
more on this. Briefly, DNF before 3.0 presented this config
value as a list...and mutating it worked. DNF from 3.0 until
3.6 presented it as a list...mutating it didn't work, but also
didn't *fail*, so this has actually not been doing anything on
DNF 3.x but we haven't noticed.
In DNF 3.6 values like this are presented as tuples instead of
lists, to try and catch usages like this, and it worked! We
need to change this one.
There is an additional weirdness here. tsflags is actually, in
libdnf terms, an OptionStringListAppend option: that means that
when something tries to *set* its value, the new value is just
appended to the existing list of values. This is very weird
behaviour when you're interacting with it like this, but
happens to be quite useful, as we can just 'set' the value to
a list like this and it will actually get appended (which is
what we want), and this one syntax happens to work correctly in
DNF 2.x, 3.0 through 3.5.1, and 3.6.

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.
Resolves: rhbz#1631561
Ends up you cannot use the kickstart user command on root, since it
already exists, so we have to translate that into a rootpw command.
So [[customizations.user]] with name = "root" only support key, which
will set the ssh key, and password which will use rootpw to set the
password. plain text or encrypted are supported.

This differs from lmc's --make-ami in that creates a full disk image instead of
an fsimage. Create a raw disk image with a / and /boot partitions, and enable
sshd, chronyd, and cockpit by default.
Remove `except` block which immediately raises the same exception again (it's
not a subclass of another caught exception, so this is safe).
Remove a false positive, because it is not emitted from the code base.
Disable subprocess-popen-preexec-fn in startProgram, which is not used
internally.
lorax uses pyanaconda's SimpleConfigParser in three different
places (twice with a copy that's been dumped into pylorax, once
by importing it), just to do a fairly simple job: read some
values out of /etc/os-release. The only value SimpleConfigParser
is adding over Python's own ConfigParser here is to read a file
with no section headers, and to unquote the values. The cost is
either a dependency on pyanaconda, or needing to copy the whole
of simpleparser plus some other utility bits from pyanaconda
into lorax. This seems like a bad trade-off.
This changes the approach: we copy one very simple utility
function from pyanaconda (`unquote`), and do some very simple
wrapping of ConfigParser to handle reading a file without any
section headers, and returning unquoted values. This way we can
read what we need out of os-release without needing a dep on
pyanaconda or to copy lots of things from it into pylorax.

In the near-future there may be /lib/modules/ directories for older
kernels with weak dependencies listed. These may not match the installed
kernel(s) so we cannot depend on them to drive generate_module_data.
Instead use the existing findkernels() function to get the list of
installed kernels and iterate those, running depmod on them.

blueprints/changes is different, each blueprint has it's own total,
limited by the call's limit. So it needs to find the max total of all
the requested blueprints.
The blueprints/changes API is a bit different from the others, the total
that it includes is for each blueprint, not one total for all of them,
since there will be a different number of commits for each.
The function is passed the dict, and it can be used to select the total
to use for retrieving all of the results. If it isn't included it will
use data["total"] which works fine in most cases.
Add a limit argument to all potentially paginated results, equal to
whatever the composer backend is the total number of results. This still
has the potential to provide truncated data if the number of results
increases between the two HTTP requests.

This adds the following optional arguments to the /compose/status route:
- type, matches the compose_type field
- status, matches the queue_status field
- blueprint, matches the blueprint field
A value of 1 is too low for heavy users of the API, such as the weldr-web
interface.
This is also systemd's default for sockets it opens. Using lorax-composer with
socket activation already results in a backlog of SOMAXCONN connections.
Currently we are making MBR disk images for qcow2 and partitioned disk,
so the UEFI packages aren't required at this point.
Move the clearpart command into compose.py so that in the futute it can
use clearpart --disklabel to create a GPT image, and add the required
packages to the package set.
The idea here is to make sure all return points have the same type for
the error cases. There's not really all that many, so they just go in
one patch. Some of these could potentially turn into more specialized
errors later.
(cherry picked from commit fd901c5e3f)
Note the exception string checking around compose_type. I didn't really
want to introduce a new exception type just for this, but also didn't
want to duplicate strings. I'd be open to other suggestions for how to
do this.

This adds some fairly redundant code to the beginning of all the
blueprint routes to attempt reading a commit from git for the
blueprint's recipe. If it succeeds, the blueprint exists and the route
can continue. Otherwise, return an error. Hopefully this doesn't slow
things down too much.

Note that this also changes the return type of uuid_info to return None
when an unknown ID is given. The other uuid_* functions are fine
because they are checked ahead of time.
