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.
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.
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.
Here's a bash_completion file for composer-cli! It completes known
commands, subcommands, and flags, plus arguments to flags that take
arguments, and if you've got write access to the socket it'll also
autocomplete:
* source names for commands that need source names
* blueprint names for commands that take blueprint names
* compose uuids for commands that take compose uuids
* intelligently only suggests appropriate uuids - e.g. only
suggests uuids of running composes for "compose cancel"
NOTE: bash completion scripts are horrible and this is no exception.
Please forgive me.
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
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.
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.
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.
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.
We need to be root to read the certificates that give access to the
package repos. Right now, the alternative seems to be changing
permissions on the certs themselves, which seems less good. We're
running anaconda as root anyway.
This adds empty __init__.py to tests so that a lib.py library of helper
functions can be imported from the tests.
Add captured_output to use with composer-cli tests to capture stdout/err
output from the functions.
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.
This will cause systemd to delete the lock file when the service
terminates. This does not do anything if lorax-composer is started on
the command line, however.
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).
