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.

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.

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.
(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.

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 patch does two things:
1) Add "compose list", which lists compose UUIDs and other basic info,
2) Fix up "blueprints list", "modules list", "sources list", and
"compose types" so their output is just a plain list of identifiers
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.

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)
Some results have errors and no status, others have status and errors.
Update the function to return the final rc to exit with, and a bool
indicating whether or not to continue processing the other fields.
Add a bunch of tests for the new function to make sure I have the logic
correct.
(cherry picked from commit 35fa067219)
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).
This adds a new argument to projects_depsolve and
projects_depsolve_with_size that contains the group list, unfortunately.
I would have prefered adding a function that just returns a list of all
the contents of a group and then add that to what was being passed into
projects_depsolve. However, there does not appear to be any good way to
do that in yum aside from a lot of grubbing around in the comps object,
which I am unwilling to do.
(cherry picked from commit 5fe4b47072)
This is the same as the output at the top level, just trimmed down to
only the options for a single subcommand. It's trigged by providing
"help" or "--help" as a subcommand option.
(cherry picked from commit 954f330ace)
This isn't a real subcommand like the others. The option processing
just intercepts it and prints the output. Given that we're subcommand
based, it makes sense to support this in addition to --help.
(cherry picked from commit 3743d6d208)
Depsolve the packages included in the templates and report any errors
using the /api/status 'msgs' field. This should help narrow down
problems with package sources not being setup correctly.
Pass --dnfplugin='*' to enable all of them.
Pass --dnfplugin='plugin-name' to enable one fo them. You can use it
multiple times to enable multiple plugins. Globs work as well.
It appears that sometimes the loop device doesn't get setup properly,
this may be a race with other users of loop devices on the system, or
some other mechanism that isn't understood.
To try and prevent total failure when this happens this patch retries
the loop setup 3 times before giving up. Previously it would wait for
the loop device to appear (checking 5 times), that operation is now
executed 3 times with a new losetup attempt each time.

Use it to override the default dracut arguments (displayed as part of
the --help output). If you want to extend the default arguments they
all need to be passed in on the cmdline as well. eg.
--dracut-arg='--xz' --dracut-arg='--install /.buildstamp' ...

Make it possible to manipulate the simple and regexp
tests the LogRequestHandler class uses to check error
messages for potential error states.
This is accomplished by moving the simple and regexp test
strings to class members, where they can be easily
manipulated by users of the pylorax module.
It's also now possible to set the log request handler class
for a LogMonitor.
This functionality can then be used for example like this:
customized_log_request_handler = monitor.LogRequestHandler
customized_log_request_handler.simple_tests.remove("Call Trace:")
log_monitor = monitor.LogMonitor(install_log,
timeout=opts.timeout,
log_request_handler_class = customized_log_request_handler)
This way installation will continue even if there was a call
trace in the logs. In a similar way additional tests and regexps can be
also added.
DNF Repo.dump() function cannot be used as a .repo file for dnf due to
it writing baseurl and gpgkey as a list instead of a string. Add a new
function to write this in the correct format, and limited to the fields
we use.
Add a test for the new function.
Fix /projects/source/info to return an error 400 if a nonexistant TOML
source is requested. If JSON is used the error is part of the standard
response.
Update test_server.py to check for the correct error code.
When adding a source failed it wasn't being removed from the dnf object.
This fixes that, and returns an error when setting up the source fails.
Also adds a test for it.
This also includes detecting rawhide vs. non-rawhide releases and
adjusting the tests accordingly (some of the source names change).
We had only been indirectly pulling in GConf, and anyways
nothing was listening to these keys.
<kalev> I still think it's a fallout from 27a90d973f
Really in general, if we wanted to make changes like this
it'd probably be a lot simpler to do them on boot or so.

First is Anaconda uses 6k blocks per file for its estimate, and it
fudges by 10% so adjust for those with an extra 10% of headroom just in
case.
Second is an Anaconda bug that won't allow it to do a kickstart install
to a disk smaller than 3000 MB. There is a PR to fix it upstream, but
for now the minimum size has to be 3000e9
This adds support for the optional blueprint section [customizations].
Use it like this:
[customizations]
hostname = yourhostnamehere
[[customiations.sshkey]]
user = root
key = root user key
