[RFC 1/2] pw_mon: improve command line options

[RFC 1/2] pw_mon: improve command line options

[Aaron Conole]

In the future, we'll use this to add support for passing opts into some parts
of pw_mon.

[RFC 2/2] recheck: Add a recheck parser for patchwork comments

[Aaron Conole]

Add a recheck parsing tool that will allow for labs to build a
recheck workflow based on specific recheck labels and projects,
with an associated state machine and querying interface.

The output of the recheck parsing tool is json and can be fed to
jq or other json parsing utilities for better field support.

I am trying to understand what you are trying to accomplish with these
if statements and the while loop. Couldnt you just move everything
into the while loop so you dont have to repeat the checks? I mean, you
will probably still have to use an OR || to check both conditions,
with and without the "--" at the begining. Maybe you could use some
sort of regex to make the "--" optional and then maybe you could
combine both checks into a single check and make it much easier

But just to double check, you are trying to parse both
"--pw-instance=myinstance" and "pw-instance=myinstance". Correct?
That's the whole goal of this patch?

The lack of strings around ^-- make me really unseasy, this also
applies to the sed line. Also, with grep you can tell it to not dump
any output/error. see -s and -q options. These apply to the other grep
commands in the script as well

why is this not inside the while loop? the use of -- forbidden for
credentials via the cli?

Not exactly.  We need to keep some compatibility, so if the first
argument doesn't start with "--" then we will treat it like a legacy
parameter.

No.  Original functionality would be like:

  $ ./pw_mon project instance credentials

New functionality accepts this, and also will accept:

  $ ./pw_mon --pw-project=project --pw-instance=instance ...

Why?  You think it needs to be escaped?

Okay - I'll use -q and -s instead of redirections.

No - ^-- means only match -- at the beginning of the line.

But there's a good catch here that we don't actually preserve the
ability to set pw_credentials via a new style option.

Thank you Aaron for the patch. It looks like you spent a lot of time on it

Overall I like the patch and dont have major concerns other than the
questions I have made in-line

Thanks!

Okay, I am trying to understand what the workflow here is. I think I
understand that this script will automatically go and check the series
for comments that match "Recheck-request:". This string means that
someone asked the bot to recheck the patch/series.

This script will call into insert_recheck_request_if_needed(), which
will do a check in the database to see if we have already done a
recheck to avoid repeating checking the same patches over and over.
This is done by checking the $recheck_msgid value in the database

I like this workflow. The only thing that I do not like is that you
have to check every comment on every patch. That seems like an
expensive operation, but honestly I do not think there is a better way
to accomplish this. So if there is no better way to do it then it's
okay, let's move forward with it

I guess it wasnt very obvious to me. But what is the purpose of this
script? for us to manually add an entry in the database to run a
recheck?

No - in case the jq fails (lets say webserver had an issue), the seq_end
value will be empty.  That would cause error if we try to run '-gt'
operation.  We avoid it by testing that there is at least something
there.

Correct - if someone sends something like:

 Recheck-request: a,b,c,d

and this pw_mon script is called with filters for 'a' and 'b', it will
flag those patches in the DB.

Correct.

There isn't a different way to do it for now, but I hope to switch to
using the events API which should mean we only look at the most recent
events that come in.

No - this script cannot insert an entry.  However, it can modify
existing entries.  This lets us define a set of transitions for each
operation that might need to happen for every type that exists.  For
instance, in github, we need to kick off the new testing, then we need
to monitor for the new results, then we need to report the new results.

These could be represented by individual states.  But, for example, if
there's a future where we add an option to re-apply to a new tree or
something, we can insert a state to handle that.

What prevent us to use the events API?

Ideally we could use it everywhere, but the pw-ci project is used for
other patchwork instances.  Events API for comments is a recent change,
and not every patchwork instance is upgraded to support it (for example,
both ozlabs and kernel.org patchwork instances don't have support).

I do have some detection code, and am planning on hooking that up so
that we can detect whether events API supports comment events based on
the filters offered, but that takes some time to test and validate.

So it becomes a question of which is more important - having something
working now, or spending time with the detection code.  Either way, we
need it for older patchworks that haven't upgraded to the just released
version (some projects are still on 2.2.0).

If you think it is better to do the events path first, I can go with
that but then we severely limit which projects get support for rechecks,
and I've already gotten the feature request for both OVS and OVN - so
we'd either need to support comments polling anyway, or do the massive
work of upgrading ozlabs instance.

I agree better to work on general availability first.

Events API is an optimization. It can come later.
