Support fetching tokens from an external command

[ammachado]

Summary

• Add token_command as a third token source alongside token / token_file, so plugins can pull secrets from password managers such as BitWarden (bw get password did-jira) or 1Password (op read op://Personal/Jira/token). The command is parsed with shlex (no shell) and its stripped stdout is used as the token; failures raise ConfigError. Results are memoized per process via functools.lru_cache so multiple config sections sharing a command only invoke the external tool once.
• Precedence when more than one of token, token_file, token_command is set in a section: token > token_file > token_command, matching the existing token vs. token_file precedence — lower-precedence keys are silently ignored, same as before.
• Updated the jira, confluence, github, and gitlab plugin docstrings to document token_command and the precedence rule. Other plugins automatically gain the feature through the shared did.base.get_token helper.

Test plan

• pytest tests/unit/test_base.py::TestGetToken — 13/13 passing (5 new tests for the command source, precedence, failure modes, and memoization)
• Full pytest tests/unit -n auto clean except for pre-existing failures unrelated to token handling (nitrate/psycopg2 build needs pg_config locally; one redmine live-data test)
• CI runs the full suite with .[all] installed
• Manual smoke: configure a plugin with token_command = printf %s ... and confirm the report runs

Note on integration test count updates (tests/github/issues.sh, tests/github/pulls.sh)

@psss, while investigating CI failures in Testing Farm, I found that two items are no longer being returned by the GitHub Search API for the 2022 date range:

• teemtee/fmf#149 — missing from all "issues created/closed" queries
• teemtee/try#002 — missing from all "pull requests created" queries

Both items are still visible by direct URL, so they have not been deleted. The root cause is GitHub Search API inconsistency: the index is eventually consistent and does not guarantee that all matching items are returned, especially for older closed issues/PRs. I confirmed the failure also reproduces on main, so this is not a regression introduced by this PR. The same behavior is also observed in PRs #468 and #470.

As a short-term fix I updated the expected counts and dropped the specific rlAssertGrep assertions for the two missing items.

I'd like your advice on how to handle this long-term. A few options I can think of:

1. Keep exact counts (current approach) — simple to read, but requires manual updates whenever the Search index drifts. Will happen again.
2. Drop count assertions entirely — only assert that specific known items are present/absent. More resilient to index drift, but loses the sanity check that ensures we're not silently fetching zero results.
3. Use a lower-bound check — e.g. assert the count is >= N rather than == N. Beakerlib doesn't support this natively but it could be done with a small shell snippet.
4. Pin the test to a narrower, stable date range where the result set is small enough that index drift is unlikely to drop items.

What is the preferred approach for this project?

[psss]

@ammachado, thanks for looking into the test issues. Yes, it really seems that some of the expected issues are not included in the search results anymore. Interestingly, for pull requests your changes seem not needed anymore. Something weird is happening on the GitHub side. Here's a slightly modified version of your adjustments:

• Modify github test data #473

[psss]

Thanks much for implementing this! Looks good, just two minor comments. Also the following statement from the pull request description is not valid, right?

• Breaking change: setting more than one of token, token_file, token_command in a section is now a hard ConfigError. Previously the lower-precedence keys were silently ignored.

[psss]

Thanks for the changes. Added one more missing pre-commit dependency in 4cd37b4. Should be good to go.

LGTM, finally a safer way to store tokens

[kwk]

I do like the idea of using Bitwarden. But I'm sorry but I have a few questions and annotations.

[kwk]

Suggested change

	token_file = <authentication-token-file>
	token_command = <command-to-fetch-token>

[kwk]

Since both, token and token_file are already listed, I think we should add the token_command as well.

[ammachado]

Added in 1f3a204.

[kwk]

Suggested change

	token_file = ~/.did/jira_api_token
	token_command = <command-to-fetch-token>

[kwk]

Same here.

[ammachado]

Added in 1f3a204.

[kwk]

I'm a bit confused what "without a shell" means here. Will there be no environment variables available when the command is run? The reason I ask is that for bitwarden you need the BW_SESSION env var to be set.

[ammachado]

Fair point, the wording was misleading. "Without a shell" only meant that the argv is built with shlex.split() and handed straight to subprocess.run() instead of going through /bin/sh. The environment is untouched: subprocess.run() inherits os.environ by default, so BW_SESSION (and OP_SERVICE_ACCOUNT_TOKEN, GNUPGHOME, etc.) are visible to the command.

What you do not get is shell expansion: no pipes, no redirects, no $VAR substitution, no globbing. So bw get password did-jira works, but bw get password did-jira | tr -d '\\n' would not. sh -c '...' still works if someone really wants a pipeline.

Documented that explicitly in 1f3a204, both in the jira plugin docstring and in the _run_token_command docstring.

[kwk]

I wonder if it is such a good idea to cache passwords?

[ammachado]

Worth spelling out, since "cache" is a loaded word for secrets.

This is an lru_cache on a module-level function, so it lives entirely in the process heap and dies with it. Nothing is written to disk, no temp file, no keyring, no cross-invocation state. did is a short-lived CLI, so "lifetime of the process" is the duration of one report.

It also does not widen exposure: get_token() returns the token to its caller, which hands it to the plugin, which keeps it on the session object for the whole run. The secret is already resident in memory for at least as long as the cache holds it. Dropping the lru_cache would not remove the token from memory, it would just make us shell out to the password manager once per config section.

That last part is the actual motivation. A config with [jira], [gitlab] and [github] all pointing at the same token_command would otherwise trigger three separate bw get/op read calls, each with its own network round trip and, for some setups, its own biometric or PIN prompt. Failures are deliberately not cached, so a transient error can be retried.

Documented the reasoning in 1f3a204. If you would still rather not keep it, the alternative I would suggest is caching per Config instance instead of per process, but that is a larger change and I do not think it buys real security.

[kwk]

I think it does make sense to show the actual command in all cases FileNotFoundError, TimeoutExpired, CalledProcessError.

[ammachado]

Agreed, fixed in 1f3a204. The command line is now in all three messages:

Token command not found: bw: bw get password did-jira
Token command timed out after 30s: bw get password did-jira
Token command failed (exit 1): bw get password did-jira: You are not logged in.

FileNotFoundError keeps exc.filename as well, since that names the specific binary that is missing, which is not obvious when the command is something like sh -c '...'.

[kwk]

Typo?

Suggested change

	# Clear the per-process token-command cache so memoized results
	# Clear the per-process token-command cache so memorized results

[ammachado]

Not a typo, "memoized" is the standard term for what functools.lru_cache does, and codespell in the pre-commit config does not flag it. But it clearly read as one, which is reason enough, so I reworded it to "cached results" in 1f3a204. Same meaning, no double-take.

[kwk]

Same here. Why make this change in this PR?

[ammachado]

These three assertions are the direct consequence of the color() change in did/utils.py, answered in detail there: #469 (comment)

Short version: the reset sequence emitted by color() changed from \033[1;m to \033[0m, so the expected strings had to follow or the tests fail. They are not an independent change, and if the utils.py change gets split out into its own PR these three go with it.

[kwk]

see above

[ammachado]

Same as above: follows the color() reset change. #469 (comment)

Why do we need those dependencies added in this PR?

[ammachado]

The pylint hook was failing with import-error across the plugin modules. import-error is not in the disable= list in .pylintrc, and pre-commit runs each hook in its own isolated virtualenv, so the init-hook sys.path extension only ever sees the hook's own venv. Without these, pylint cannot resolve feedparser, koji, nitrate, bodhi-client and friends, and reports an error per plugin.

This is not a new pattern, it is the same list the mypy hook right below already carries:

  - repo: https://github.com/pre-commit/mirrors-mypy
    hooks:
      - id: mypy
        additional_dependencies: [
            bodhi-client,
            feedparser,
            google-api-python-client,
            ...

The pylint hook was simply missing the equivalent. The difference in the two lists is that pylint needs the real packages where mypy wants the stubs, hence requests and python-dateutil instead of types-requests and types-python-dateutil.

Fair to ask why it landed here rather than separately, and the honest answer is that it surfaced while getting the full pre-commit suite green for this branch. Worth noting @psss reviewed it and then added setuptools to the same list himself in 4cd37b4, so the list as it stands is partly his. I can still split it into a standalone PR if you would rather keep this one narrow.

[ammachado]

@kwk, all fourteen threads from your review are answered, and the branch is rebased on current main. Could you take another look when you have a moment?

Changed in 179036d:

• token_command added to the gitlab and jira config examples, next to the token / token_file entries that were already listed
• Clarified "without a shell": the command inherits did's environment, so BW_SESSION and friends are visible. Only shell expansion is missing (no pipes, redirects, $VAR, globs). Documented in both the jira plugin docstring and _run_token_command
• The command line is now included in all three error paths, not just the timeout one
• Documented why caching the token for the process lifetime does not widen exposure of the secret
• Reworded the "memoized" comment that read as a typo

Answered without a code change, reasoning in each thread:

• Optional[str] stays, since setup.py still declares Python 3.9 and PEP 604 is 3.10+. from __future__ import annotations would let us switch, but repo-wide rather than in this PR
• did/stats.py: the old line printed a Future repr, and a failing token_command surfaces through exactly that line
• did/utils.py colour reset and the three test assertions that follow from it: I overstated this as a bug fix in the commit message, it is a cleanup. Corrected in the thread
• .pre-commit-config.yaml: pylint was hitting import-error, mirroring the list the mypy hook already carries

I offered in several threads to split the colour-reset and pre-commit changes into separate PRs if you would still prefer this one narrower. Happy to do that, just say which.

One note on CI: the four Fedora testing-farm jobs are red, but not because of this branch. pagure.io's REST API is currently returning 404 for every path, including https://pagure.io/api/0/version, while the web UI is up. That fails the five tests/unit/plugins/test_pagure.py tests. The same five fail on unmodified main, and this PR touches no pagure code. The CentOS Stream jobs pass because they do not run the unit plan.

[kwk]

Okay, let me make one thing clear, I like the feature. But I also like Big Buts (the song is cool as well but written differently).

Can we please get a policy for AI contributions? I simply do not buy that my last review was answered by a human. And I refuse to work this way.

I'm getting really angry about such comments. Not because they are incorrect or inaccurate but because I feel like someone is operating a machine instead of thinking for him or herself. This is disrespectful.

@psss please look at the responses and tell me this was written by a person.
