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.
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.
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.

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
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.
(cherry picked from commit b3bb438254)
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.
(cherry picked from commit a925cc7ddb)
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.
(cherry picked from commit 6497b4fb65)
Each element in the errors value is now a dict, with a msg field and an
id field. The id field contains a value out of errors.py that can be
used by the front end to key on. The msg field is the same as what's
been there.
The idea is to keep the number of IDs somewhat limited so there's not a
huge number of things for the front end to know.
(cherry picked from commit 9677b012da)
This should make it easier to return more complex error structures. It
also doesn't appear to matter - tests still pass without changes.
(cherry picked from commit 4c3f93e329)
Make sure no UTF8 characters are allowed and return an error if they
are.
Also includes tests to make sure the correct error is returned.
(cherry picked from commit 86d79cd8a6)
Currently the code is not UTF8 safe, so we need to return a clear error
when invalid characters are passed in.
This also adds tests for the routes to confirm that an error is
correctly returned.
(cherry picked from commit 74f5def3d4)
This handles the case where a route is requested, but without a required
parameter. So, /blueprints/info is requested instead of
/blueprints/info/http-server. It accomplishes this via a decorator, so
a lot of these route-related functions now have quite a few decorators
attached to them.
Typo'd URLs (/blueprints/nfo for instance) will still return a 404. I
think this is a reasonable thing to do.
(cherry picked from commit 5daf2d416a)
Unfortunately, this isn't very useful if /modules/info is provided with
multiple modules. yum doesn't traceback when doPackageLists is given
something that doesn't exist. It just returns an empty list. If
/modules/info is given just one module and yum gives us an empty list,
it's easy to say what happened. If /modules/info is given several
modules and just one does not exist, we will not be able to detect that.
Fixing this would require doing more yum operations, which is likely to
slow things down and isn't the direction I want to be going.
(cherry picked from commit 8e948e4a4d)
Right now, this is when the compose is queued up, when it is started by
anaconda, and when it is finished (whether that's success or not).
(cherry picked from commit 3ba9d53b8b)
If one of the timestamps isn't present (for instance, the finished
timestamp for a job that is still running), null is returned.
(cherry picked from commit 17c40ef271)
This is responsible for writing out a new times.toml file, containing
important timestamps in the life of a compose. This seems a little more
reliable than attempting to infer things from the filesystem, especially
in light of the fact that we can't ever really know when a file was
created.
(cherry picked from commit b59d59b124)
A bad system repo can cause lorax-composer to fail to start. Instead of
a traceback log the error and exit.
(note that the exit still results in an OSError traceback due to part of
it running as root, this needs to be addressed in another commit).
