Typo on command ("pip3 install -") line causes cascading exceptions #5147

gvanrossum · 2018-04-02T17:26:01Z

Pip version: pip 10.0.0b2 from /Users/guido/v37/lib/python3.7/site-packages/pip (python 3.7)
Python version: anything between 3.3 and 3.7
Operating system: Mac

Description:

I made a typo on the command line and accidentally ran pip3 install -. I expected a nice error message. ~~Instead~~ I got one, but in addition I got two tracebacks.

What I've run:

$ pip3 install -
Invalid requirement: '-'

pradyunsg · 2018-04-02T18:23:58Z

pip/src/pip/_internal/req/req_install.py

Line 260 in c2a4ea4

add_msg = traceback.format_exc()

I'm not sure what's the right thing to print here is but it's definitely not printing the Traceback. :)

Other Options:

nothing extra, suppress the error message
error message (contains "parse error at")
useful information for ParseException

I'm tempted to investigate the last one but really all of these are an improvement in some way over the current.

Worth noting that this is also an issue with pip 9, so, I'd say changing this counts as an enhancement, not a regular bug-fix.

pfmoore · 2018-04-02T19:02:54Z

I'd probably count this as a bug (as @gvanrossum says, we should just print the error message, not the traceback too). But it's only cosmetic, and as it was present in pip 9, and we're in the 10.0 beta now, I'd like to defer this to post-10.0 for fixing.

Closes: pypa#5147

pradyunsg · 2018-07-09T03:24:49Z

Pushing this down the road to the next release since I don't think the corresponding PR will be ready in time for 18.0.

pradyunsg · 2018-07-18T11:25:50Z

Reopened since pip would still show a traceback, though the message is better.

xavfernandez · 2018-07-18T11:31:00Z

This would require a release of packaging first :)

pradyunsg · 2018-07-18T13:20:18Z

Yeah. And vendoring of the newer release into pip, which should be what closes this issue. :)

pradyunsg · 2018-09-18T14:03:31Z

If we don't have a packaging release by 28th of this month, I'll push this change to a later release.

dstufft · 2018-09-18T14:26:32Z

I can give someone else access to release packaging.

pradyunsg · 2018-09-18T16:28:32Z

I'll be happy to do so.

pradyunsg · 2018-09-26T06:28:37Z

Cool. Just released packaging 18.0; I'll make the corresponding pip updates and relevant change to pip itself before the weekend.

pradyunsg · 2018-10-03T15:13:43Z

ISTM, the changes made for packaging, are not enough to make this error message better/perfect.

This isn't really a major bug anyway so I'm not going to block 18.1 for this.

atse · 2018-10-26T10:38:45Z

Would treating - as stdin be considered a useful feature here?

pradyunsg · 2019-01-18T06:48:33Z

Closing since this has been fixed at some point:

The agent can be installed using easy_install/pip/distribute via the Python Package Index or can be downloaded directly from the New Relic download site. Features AWS operation and request ID will now be reported in transaction traces and spans when using boto3 and botocore. The agent will now report aws.requestId and aws.operation for all calls to AWS made using botocore and boto3. DynamoDB calls are now reported under the Databases tab. The agent will now record DynamoDB query performance in the Databases tab in APM in addition to table name for the following calls: put_item get_item update_item delete_item create_table delete_table query scan Certain SQS calls will now report additional data for spans and transaction traces. The agent will now record the queue name in spans and transaction traces for the following SQS calls: send_message send_message_batch receive_message SNS publish will now report additional data for spans and transaction traces. The SNS topic, target, or the string literal PhoneNumber will be reported to New Relic inside of spans and transaction traces. The full URL path will now be recorded on span events and transaction traces when using boto3 or botocore. The agent will now record the full URL path for API calls made to AWS through the boto3 / botocore libraries. The path will be available through span events and transaction traces. Bug Fixes Using newrelic-admin to start a GunicornWebWorker with an application factory resulted in an application crash.

This fixes a number of surprising issues like ``setup_method`` being called before session-scoped autouse fixtures (see `517 <https://github.com/pytest-dev/pytest/issues/517>`__ for an example). - `4627 <https://github.com/pytest-dev/pytest/issues/4627>`_: Display a message at the end of the test session when running under Python 2.7 and 3.4 that pytest 5.0 will no longer support those Python versions. - `4660 <https://github.com/pytest-dev/pytest/issues/4660>`_: The number of *selected* tests now are also displayed when the ``-k`` or ``-m`` flags are used. - `4688 <https://github.com/pytest-dev/pytest/issues/4688>`_: ``pytest_report_teststatus`` hook now can also receive a ``config`` parameter. - `4691 <https://github.com/pytest-dev/pytest/issues/4691>`_: ``pytest_terminal_summary`` hook now can also receive a ``config`` parameter. Bug Fixes --------- - `3547 <https://github.com/pytest-dev/pytest/issues/3547>`_: ``--junitxml`` can emit XML compatible with Jenkins xUnit. ``junit_family`` INI option accepts ``legacy|xunit1``, which produces old style output, and ``xunit2`` that conforms more strictly to https://github.com/jenkinsci/xunit-plugin/blob/xunit-2.3.2/src/main/resources/org/jenkinsci/plugins/xunit/types/model/xsd/junit-10.xsd - `4280 <https://github.com/pytest-dev/pytest/issues/4280>`_: Improve quitting from pdb, especially with ``--trace``. Using ``q[quit]`` after ``pdb.set_trace()`` will quit pytest also. - `4402 <https://github.com/pytest-dev/pytest/issues/4402>`_: Warning summary now groups warnings by message instead of by test id. This makes the output more compact and better conveys the general idea of how much code is actually generating warnings, instead of how many tests call that code. - `4536 <https://github.com/pytest-dev/pytest/issues/4536>`_: ``monkeypatch.delattr`` handles class descriptors like ``staticmethod``/``classmethod``. - `4649 <https://github.com/pytest-dev/pytest/issues/4649>`_: Restore marks being considered keywords for keyword expressions. - `4653 <https://github.com/pytest-dev/pytest/issues/4653>`_: ``tmp_path`` fixture and other related ones provides resolved path (a.k.a real path) - `4667 <https://github.com/pytest-dev/pytest/issues/4667>`_: ``pytest_terminal_summary`` uses result from ``pytest_report_teststatus`` hook, rather than hardcoded strings. - `4669 <https://github.com/pytest-dev/pytest/issues/4669>`_: Correctly handle ``unittest.SkipTest`` exception containing non-ascii characters on Python 2. - `4680 <https://github.com/pytest-dev/pytest/issues/4680>`_: Ensure the ``tmpdir`` and the ``tmp_path`` fixtures are the same folder. - `4681 <https://github.com/pytest-dev/pytest/issues/4681>`_: Ensure ``tmp_path`` is always a real path. Trivial/Internal Changes ------------------------ - `4643 <https://github.com/pytest-dev/pytest/issues/4643>`_: Use ``a.item()`` instead of the deprecated ``np.asscalar(a)`` in ``pytest.approx``. ``np.asscalar`` has been `deprecated <https://github.com/numpy/numpy/blob/master/doc/release/1.16.0-notes.rstnew-deprecations>`__ in ``numpy 1.16.``. - `4657 <https://github.com/pytest-dev/pytest/issues/4657>`_: Copy saferepr from pylib ``` </details> <details> <summary>Links</summary> - PyPI: https://pypi.org/project/pytest - Changelog: https://pyup.io/changelogs/pytest/ - Homepage: https://docs.pytest.org/en/latest/ </details> ### Update [pytest-mock](https://pypi.org/project/pytest-mock) from **1.10.0** to **1.10.1**. *The bot wasn't able to find a changelog for this release.
