[dpdk-ci] [PATCH 0/9] Automatic patchwork delegation

[dpdk-ci] [PATCH 0/9] Automatic patchwork delegation

[Ali Alnubani]

This patchset adds support for automatic patch delegation.

The script 'guess_git_tree.py' was renamed to 'maintainers.py'
and now supports finding patch and series maintainers. It can also
delegate patches to them using git-pw.

The script 'poll-pw' was rewritten to fetch new api resources
by filtering with date and project. It now supports fetching both
patches and series.

Ali Alnubani (9):
  tools: rename guess_git_tree script
  tools: match by tree url instead of tree name
  tools: update script usage
  tools: add functionality for detecting tree maintainers
  tools: add functionality for setting pw delegates
  add git-pw to requirements file
  tools: filter new patchwork IDs by date
  tools: add support for fetching new series IDs
  tools: filter new patchwork IDs by project name

[dpdk-ci] [PATCH 1/9] tools: rename guess_git_tree script

[Ali Alnubani]

The name 'maintainers.py' will make more sense when
adding more operations to the script.

[dpdk-ci] [PATCH 2/9] tools: match by tree url instead of tree name

[Ali Alnubani]

The tree url has more information. It can be used to
get the maintainer of a tree, and it includes the tree name anyway.

Also try to use named capture groups as much as possible.

[dpdk-ci] [PATCH 3/9] tools: update script usage

[Ali Alnubani]

The resource type (whether it's a patch or a series) is now
specified by the new argument --type.
Both commands: list_trees_for_patch & list_trees_for_series
are replaced by the command: list_trees, and the type must
be always set.

This makes adding more operations require less arguments
and easier.

[Ali Alnubani]

Detecting a maintainer works by searching the
'General Project Administration' section for subsections
containing the provided tree, and then returning the maintainers
specified in that subsection.

[dpdk-ci] [PATCH 7/9] tools: filter new patchwork IDs by date

[Ali Alnubani]

API resource IDs are guaranteed to be unique, but they aren't guaranteed
to have no gaps, for example, the following series IDs are
nonexistent: 16157, 17181, 18235.
Filtering by the date since the last check is necessary to later
add support for fetching new series IDs in addition to patch IDs.

Instead of requiring a file that contains the next patch ID,
a file containing the timestamp of the last time the API was fetched
is now used.
Each time the API is fetched for new patches, the timestamp
in the file gets updated, and the script sleeps an amount of time specified
by PAUSE_SECONDS before attempting to fetch new resources again.

The pause amount between each poll attempt is still 100 seconds.

Setting the env variable 'TZ' might be necessary if your timezone
doesn't match the server's timezone.

The package jq (Command-line JSON processor) is now required by the
script.

Example usage:
$ export TZ="Europe/Paris"
$ export MAINTAINERS_FILE_PATH=/path/to/dpdk/MAINTAINERS
$ ./tools/poll-pw /path/to/last.txt \
    '/path/to/maintainers.py --command set_pw_delegate --type patch $1'

[dpdk-ci] [PATCH 8/9] tools: add support for fetching new series IDs

[Ali Alnubani]

The script can now fetch new series IDs the same way
it fetches new patch IDs.

Example usage:
$ export TZ="Europe/Paris"
$ export MAINTAINERS_FILE_PATH=/path/to/dpdk/MAINTAINERS
$ ./tools/poll-pw series /path/to/last.txt \
    '/path/to/maintainers.py --command set_pw_delegate --type series $1'

[dpdk-ci] [PATCH 9/9] tools: filter new patchwork IDs by project name

[Ali Alnubani]

Different projects require different checks usually, this
patch modifies the script so that it requires a project's name
which it passes as a parameter with the API end point.

Example usage:

Thomas pointed out that the script can fetch the same ID twice in some cases, and that we can miss some IDs due to time synchronization. I'll look into that.

A noun evokes something non-executable and in my opinion 'maintainers.py' doesn't describe what the script does in any way.

As far as I can tell, the script (with all the new changes) gets data from patchwork and the maintainers file and then processes those to produce a list of trees, maintainers or updates PW. Maybe name it pw_maintainers_cli.py?

Another thing that would make sense it to make the "--command" argument positional, since it's mandatory and the argument name isn't really necessary. But maybe that's a change for another series.

Thanks for taking a look Juraj, I agree with the name you suggested, and I'll update in v2.
I'll also try to implement your second suggestion in that version.

[dpdk-ci] [PATCH v2 00/10] Automatic patchwork delegation

[alialnu]

From: Ali Alnubani <alialnu@nvidia.com>

This patchset adds support for automatic patch delegation.

The script 'guess_git_tree.py' was renamed to 'pw_maintainers_cli.py'
and now supports finding patch and series maintainers. It can also
delegate patches to them using git-pw.

The script 'poll-pw' was rewritten to fetch new api resources
by filtering with date and project. It now supports fetching both
patches and series.

Ali Alnubani (10):
  tools: rename guess_git_tree script
  tools: match by tree url instead of tree name
  tools: update script usage
  tools: add functionality for detecting tree maintainers
  tools: add functionality for setting pw delegates
  add git-pw to requirements file
  tools: filter new patchwork IDs by date
  tools: add support for fetching new series IDs
  tools: filter new patchwork IDs by project name
  tools: skip the IDs we already fetched

The tree url has more information. It can be used to
get the maintainer of a tree, and it includes the tree name anyway.

Also try to use named capture groups as much as possible.

[dpdk-ci] [PATCH v2 03/10] tools: update script usage

[alialnu]

From: Ali Alnubani <alialnu@nvidia.com>

The resource type (whether it's a patch or a series) is now
specified by the new argument --type.
Both commands: list_trees_for_patch & list_trees_for_series
are replaced by the positional arg 'list_trees', and the type must
be always set.

This makes adding more operations require less arguments.

[alialnu]

From: Ali Alnubani <alialnu@nvidia.com>

Detecting a maintainer works by searching the
'General Project Administration' section for subsections
containing the provided tree, and then returning the maintainers
specified in that subsection.

[dpdk-ci] [PATCH v2 07/10] tools: filter new patchwork IDs by date

[alialnu]

From: Ali Alnubani <alialnu@nvidia.com>

API resource IDs are guaranteed to be unique, but they aren't guaranteed
to have no gaps, for example, the following series IDs are
nonexistent: 16157, 17181, 18235.
Filtering by the date since the last check is necessary to later
add support for fetching new series IDs in addition to patch IDs.

Instead of requiring a file that contains the next patch ID,
a file containing the timestamp of the last time the API was fetched
is now used.
Each time the API is fetched for new patches, the timestamp
in the file gets updated, and the script sleeps an amount of time specified
by PAUSE_SECONDS before attempting to fetch new resources again.

The pause amount between each poll attempt is still 100 seconds.

Setting the env variable 'TZ' might be necessary if your timezone
doesn't match the server's timezone.

The package jq (Command-line JSON processor) is now required by the
script.

Example usage:
$ export TZ="Europe/Paris"
$ export MAINTAINERS_FILE_PATH=/path/to/dpdk/MAINTAINERS
$ ./tools/poll-pw /path/to/last.txt \
    '/path/to/pw_maintainers_cli.py --type patch set_pw_delegate $1'

[dpdk-ci] [PATCH v2 09/10] tools: filter new patchwork IDs by project name

[alialnu]

From: Ali Alnubani <alialnu@nvidia.com>

Different projects require different checks usually, this
patch modifies the script so that it requires a project's name
which it passes as a parameter with the API end point.

Example usage:
$ export TZ="Europe/Paris"
$ export MAINTAINERS_FILE_PATH=/path/to/dpdk/MAINTAINERS
$ ./tools/poll-pw series DPDK /path/to/last.txt \
    '/path/to/pw_maintainers_cli.py --type series set_pw_delegate $1'

The only real difference is to have "next/" for trees having "next-" in their name.
And the URL prefix git://dpdk.org/ is added to provide a full URL.

I'm not sure we should skip patches which are already delegated.
If we use the command to explicitly delegate the patch,
we should do it, right?

The skip logic may be implemented at a higher level in the CI.

I'm not satisfied with this explanation.
Please explain what happens if the project is not specified,
why this change is done.
My explanation: IDs are common for all projects.
If we want to check patches of a specific project, we need this filter.

We store all IDs. Should we manually remove olds one from time to time?

We need an explanation about the strategy, why it is needed.
I think it is because filtering by date is not enough.
In order to not miss any patch, we should request a date earlier
than the previous fetch and skip those already fetched.

Where the "earlier date" is defined?

Do you have a suggestion for when should we clear this file? Maybe each time the script starts?

The reason this change was made isn't because filtering by date is not enough, it's because
I want to avoid feeding the same ID to 'callcmd' more than once.
This can happen if a patchwork ID was created between recording date_now and fetching the API.
I don't think we are missing any IDs, even without this change.

> Where the "earlier date" is defined?

There are 2 variables, "date_now", which is recorded right before fetching from the API, and then gets written
to the file, and "since", which is the last date that was written to the file.

I have mistakenly assumed that the date field I'm filtering with is the date Patchwork creates the ID, when in fact it's the date the patch was created on. I'll need to filter the /events end point instead.

Yes at each start, we can remove the very old entries, like more than 10 hours old.

Wouldn't this require using and depending on a database (at least an SQLite one) to additionally store timestamps to use for queries?
Do you have a simpler way in mind to keep track of the IDs and their timestamps to process later based on how long they have been in the file? Maybe keep only up to a certain number of IDs in this file (up to a 1000 maybe)?

Given the command is to set delegate, the force looks strange to me.
Wouldn't it be more logical to add an option to skip already delegated patches?

Isn't it safer not to force overriding the delegate by default?
Users can send patches with the header "X-Patchwork-Delegate" to set a specific delegate. Maintainers might want to set another user as the delegate when there are multiple delegates in the MAINTAINERS file for a patch. Should we override these by default?

If the purpose is to not allow the script to grow indefinitely, is it ok to just cut the file by half once it reaches a specific number of lines (like 1000)?.
Do you agree with this approach? It'd be easier to implement compared to storing and processing timestamps.

These considerations don't contradict with the option name.
If we have the option --skip-delegated (or --only-non-delegated),
we can always use this option in the automatic run.

But for a manual run, I expect the script to delegate a patch
the user explicitly wants to set, without requiring a "force" option.

[dpdk-ci] [PATCH v4 00/10] Automatic patchwork delegation

[Ali Alnubani]

This patchset adds support for automatic patch delegation.

The script 'guess_git_tree.py' was renamed to 'pw_maintainers_cli.py'
and now supports finding patch and series maintainers. It can also
delegate patches to them using git-pw.

The script 'poll-pw' was rewritten to fetch new api resources
by filtering with date and project. It now supports fetching both
patches and series.

[dpdk-ci] [PATCH v4 02/10] tools: match by tree URL instead of tree name

[Ali Alnubani]

The tree URL has more information. It can be used to
get the maintainer of a tree, and it includes the tree name anyway.
Although we can construct the tree URL by prepending
"git://dpdk.org/next/" to the trees that have "next-" in their name,
and prepending "git://dpdk.org/" to anything else, it would be safer
to read the URL from the MAINTAINERS file just in case new trees that
don't follow this rule were added.

Also try to use named capture groups as much as possible.

[dpdk-ci] [PATCH v4 03/10] tools: update script usage

[Ali Alnubani]

The resource type (whether it's a patch or a series) is now
specified by the new argument --type.
Both commands: list_trees_for_patch & list_trees_for_series
are replaced by the positional arg 'list-trees', and the type must
be always set. This makes adding more operations require less arguments.

Additionally, use the more common dashes in argument names instead
of underscores.

[dpdk-ci] [PATCH v4 05/10] tools: add functionality for setting pw delegates

[Ali Alnubani]

A new command was added to set patch delegates in Patchwork
based on the emails found in DPDK's MAINTAINERS file.

Example usage:
  $ export MAINTAINERS_FILE_PATH=/path/to/dpdk/MAINTAINERS
  $ ./pw_maintainers_cli.py --type series set-pw-delegate SERIES_ID

Changes in v3:
- Added an argument to force overriding delegates.
Changes in v4:
- Force overriding delegates by default, and add an arg to
  change that behavior (Suggested by Thomas Monjalon).
- Shorten link in set_delegate's doc.

[dpdk-ci] [PATCH v4 07/10] tools: filter new Patchwork IDs by date

[Ali Alnubani]

API resource IDs are guaranteed to be unique, but they aren't guaranteed
to have no gaps, for example, the following series IDs are
nonexistent: 16157, 17181, 18235.
Filtering by the date since the last check is necessary to later
add support for fetching new series IDs in addition to patch IDs.

The script now periodically fetches Patchwork's events API filtering
by the 'patch-completed' category (see [1]). It parses the responses using jq
and passes the IDs to 'callcmd'.

Instead of requiring a file that contains the next patch ID,
a file containing the timestamp of the last time the API was fetched
is now used. Each time the API is fetched for new patches, the timestamp
in the file gets updated, and the script sleeps an amount of time specified
by PAUSE_SECONDS before attempting to fetch new resources again.
There are 2 variables, 'date_now', which is recorded right before
fetching from the API, and then gets written to the file, and 'since',
which is the last date that was written to the file.

Since API responses can be in multiple pages, the script will keep
attempting to fetch the next page until jq encounters an error while
parsing a non list response with no 'payload' key.

The pause amount between each poll attempt is still 100 seconds.

The script writes the date in Universal Time (UTC) format and
expects to read the same format from the file as Patchwork stores event
objects with a naive datetime object that is not aware of the
server's timezone (see [2] and [3]).

The package jq (Command-line JSON processor) is now required by the
script.

Example usage:
$ export MAINTAINERS_FILE_PATH=/path/to/dpdk/MAINTAINERS
$ ./tools/poll-pw /path/to/last.txt \
    '/path/to/pw_maintainers_cli.py --type patch set-pw-delegate $1'

[3] https://docs.python.org/3/library/datetime.html#datetime.datetime.utcnow

Signed-off-by: Ali Alnubani <alialnu@nvidia.com>
---
Changes in v2:
- Removed an unnecessary 'break' statement in the for loop.
Changes in v3:
- Fetch the events API endpoint for new patches as the date field in the
  /patches and /series endpoints is the mbox creation date, not
  the date they were created in Patchwork.
- Use UTC date format.
- Redirect error messages to stderr.
- Fixed typo in usage (specifed -> specified).

Changes in v3:
- Fetch new series IDs by filtering the events API with
  category "series-completed".
- Updated usage (renamed 'patches' arg to 'patch') so that
  it feeds directly into the 'patch-completed' category.

[dpdk-ci] [PATCH v4 09/10] tools: filter new patchwork IDs by project name

[Ali Alnubani]

If the script doesn't filter by project, it would be fetching patches
from all projects, which we don't want as different projects
require different checks usually. This patch modifies the script so
that it requires a project's name to fetch IDs for.

Example usage:
$ export MAINTAINERS_FILE_PATH=/path/to/dpdk/MAINTAINERS
$ ./tools/poll-pw series DPDK /path/to/last.txt \
    '/path/to/pw_maintainers_cli.py --type series set-pw-delegate $1'

Signed-off-by: Ali Alnubani <alialnu@nvidia.com>
---
Changes in v3:
- Filter by project using jq, since the events API doesn't have a
  'project' parameter.
- Redirect error messages to stderr.

[dpdk-ci] [PATCH v4 10/10] tools: skip the IDs we already fetched

[Ali Alnubani]

To avoid calling 'callcmd' more than once for an ID, which can happen
if a Patchwork ID was created between recording 'date_now' and fetching
the API, store the IDs we already fetched in a file and don't run 'callcmd'
again for any ID that exists in the file while keeping the number of
entries less than 1000 in that file.

The file is now cut in half each time it reaches 1000 entries. See v4:

Thanks for the feedback, updated in v4 and added a --skip-delegated arg instead:
