Release v179 (#1073 )

Tests: Remove redundant Python version tests (#1075 )
There were previously 6 virtually identical tests checking the handling of a non-existent Python version being specified in `runtime.txt`. Only one is necessary - removing the rest will improve CI run time. Closes @W-8110383@. [skip changelog]

Ed Morley	215a3e3670	Release v179 (#1073 )	2020-09-23 11:15:54 +01:00
Ed Morley	4505968fcb	Tests: Remove redundant Python version tests (#1075 ) There were previously 6 virtually identical tests checking the handling of a non-existent Python version being specified in `runtime.txt`. Only one is necessary - removing the rest will improve CI run time. Closes @W-8110383@. [skip changelog]	2020-09-22 18:48:31 +01:00
Ed Morley	37d1474bee	Tests: Prevent shadowing of the Python 3.7 version warning test (#1074 ) Previously the test for Python 3.8 version warnings was named the same as an earlier test for Python 3.7, meaning the earlier test definition was overwritten and so never run. The later test has now been renamed to the correct version, and the test ordering adjusted for consistency with the rest of the file. Closes @W-8110123@. [skip changelog]	2020-09-22 18:04:11 +01:00

Ed Morley	64fb396b73	Remove duplicate pipenv metric event (#1070 ) Since the `tool.pipenv` event is being emitted twice per pipenv build, inflating its usage. This whole file could do with a massive refactor (4 levels deep of conditionals is never a good sign), but that can wait until a later PR. In the future it would also be great to have testing of metrics events. Closes @W-8094963@.	2020-09-18 19:04:28 +01:00
Ed Morley	eb6ee49dfe	Emit metrics for how the Python version was chosen (#1069 ) Currently an app's Python version can be set via a few different means: - explicitly by the user (via `runtime.txt` or `Pipfile.lock`) - implicitly via the sticky versions feature (for existing apps) - implicitly via default version for new apps / those with empty cache In order to determine the priority of features like automatic Python patch version upgrades for sticky-versioned apps, it's useful to have metrics for these. There were previously no tests for either the sticky versions feature, or changing the Python version by updating the `runtime.txt` file, so I've added some now (given that I updated the conditional to add the metrics, so useful to have coverage). I've also removed the confusing overwrite of `DEFAULT_PYTHON_VERSION` with the cached version, and kept them as two separate variables. Closes @W-8099632@. Closes @W-8099645@.	2020-09-18 18:48:57 +01:00
Ed Morley	64abfb2978	Emit Python version metric events for all builds (#1066 ) Previously the metric events describing the chosen Python version were only emitted when that Python version was installed, and not when it was being used from the build cache (the common case). Now the version is emitted for all builds, improving visibility into the distribution of Python usage, and helping determine the priority of features like opt-in automatic Python patch updates. Closes @W-8059668@.	2020-09-16 12:28:15 +01:00
Ed Morley	12d1cbb3be	Tests: Switch to branch 'main' of python-getting-started repo (#1065 ) Since the default branch for that repository has been changed from `master` to `main` in W-7903771. Closes @W-8047331@. [skip changelog]	2020-09-16 12:21:53 +01:00

Ed Morley	7c4f55bc32	Switch the remaining build formulas to the shared script approach (#1049 ) To be consistent with the other build formulas after #799. Refs @W-7947035@. [skip changelog]	2020-08-12 15:19:53 +01:00
Ed Morley	eabe71d578	Update the Python 3.4.10 build script to use the correct Python version (#1048 ) The existing Python 3.4.10 archive actually contained Python 3.7.2, since the version in the source URL was not updated when the file was created in #813. The build formula now uses the shared build script approach like all of the other build scripts, which ensures the version can never get out of sync (since it's extracted from the formula filename). The build for Heroku-18 failed to compile `_ssl` properly (even though the build exited zero) since Python 3.4.10 is old enough it doesn't work well with libssl1.1. Installing `libssl1.0-dev` in the build image locally resolved the issue - however we don't want to use that in the future for newer Python, so I've not updated the `heroku-18.Dockerfile`. In addition, with the rebuilt archives the tests now pass on Cedar-14, so no longer need to be marked as failing. Closes @W-7947035@.	2020-08-12 15:19:31 +01:00
Ed Morley	95fca53d38	Travis: Correctly skip Hatchet on PRs from forks (#1045 ) The Hatchet run requires a valid Heroku login, the credentials for which are set via Travis secure environment variables, which by design are not revealed to PRs from forks. The previous conditional wasn't working as intended - the Hatchet job was still being triggered for forks from PRs. The new conditional fixes this, and also means that forks could set their own credentials via Travis environment variables if they wanted a way to run the tests in CI on their own repo. See: https://docs.travis-ci.com/user/conditions-v1 Fixes #1019. Closes @W-7918482@. [skip changelog]	2020-08-12 11:17:38 +01:00
Ed Morley	ff4f677435	Travis: Remove Hatchet credentials from .travis.yml (#1047 ) Since they are now set via the Travis repository level secrets feature instead. This both works around the Travis bug seen in #1045, and also means its easier to set up Travis on forks, since otherwise the `.travis.yml` secrets would overwrite the global secrets. As part of this move the test account used has also been changed, and will be documented here: https://github.com/heroku/languages-team/blob/main/guides/create_test_users_for_ci.md#known-usernames Closes @W-7949880@. [skip changelog]	2020-08-12 10:49:57 +01:00
Ed Morley	cba3201ac2	Rename confusing PYPY_* variables (#1044 ) Since these variables refer to the latest version of PyPy, compared to the similarly named `PYPY27` and `PYPY36` variables (ie same name except without the underscore) which refer to the major/minor version only. The similar names caused me to use the wrong one locally whilst working on another PR, which was caught by tests but demonstrates why we should rename them. Closes @W-7935256@. [skip changelog]	2020-08-11 19:31:53 +01:00
Ed Morley	ac29db32f8	Remove unused vendor/test-utils (#1043 ) Since the unit tests instead use the utilities in this separate file: https://github.com/heroku/heroku-buildpack-python/blob/419ef479969c4d5945f2c0620292229ef464f4c8/test/utils A changelog entry has been added since whilst this file is for internal testing only, the buildpack's `vendor/` directory is put on `PATH`, so in theory it could have been called outside the buildpack (though this seems extremely unlikely since the script isn't very useful externally). Fixes #1027. Closes @W-7918496@.	2020-08-11 19:31:07 +01:00
Ed Morley	e83576f6b4	Remove unused .pre-commit-config.yaml (#1042 ) Since we don't use that tool (<https://pre-commit.com>), and there are better alternatives should we want to expand coverage of these kind of things. Closes @W-7923935@. [skip changelog]	2020-08-11 19:21:40 +01:00
Ed Morley	43600f25a5	Remove unused etc/ci-setup.sh (#1041 ) It stopped being used as of #781. ``` $ rg ci-setup.sh --stats 0 matches $ git-content-search ci-setup.sh `e7da63f` update to newer hatchet integration M .travis.yml `576def4` fix travis dependency blocker M .travis.yml $ git show `e7da63f` \| rg ci-setup.sh -C 1 -before_install: - - sudo bash etc/ci-setup.sh + - bundle exec hatchet ci:setup ``` Hatchet embeds its own setup script, which is called via the rake task: https://github.com/heroku/hatchet/blob/v6.0.0/etc/ci_setup.rb Closes @W-7923930@. [skip changelog]	2020-08-11 19:21:03 +01:00
Ed Morley	f508bd538d	Fix the security update version check message for PyPy (#1040 ) Previously if an app was using an older version of PyPy, the buildpack would show a confusing "Could not find that version" message (even though the version was found), when it really meant to warn about there being a newer release available. It looks like the version check messages were perhaps copied and pasted from something else, but the message wording not updated at the time. I've also added tests since there were none for this feature. Fixes #1004. Closes @W-7918745@.	2020-08-11 19:15:16 +01:00

The native integration now supports updating not only security updates, but all dependencies - however this must be explicitly enabled by adding a config file: https://docs.github.com/en/github/administering-a-repository/enabling-and-disabling-version-updates The config options are described here: https://docs.github.com/en/github/administering-a-repository/configuration-options-for-dependency-updates Closes @W-7937066@.

Ed Morley	99c1027cb2	Tests: Update Hatchet dependencies (#1036 ) * `bundler update` * Ruby 2.6 -> 2.7 * Remove unnecessary bundler version downgrade Of note this picks up: https://github.com/grosser/parallel_split_test/pull/20 @W-7930909@ [skip changelog]	2020-08-10 11:29:34 +01:00
Ed Morley	46d3d2b042	Travis: Move hatchet ci:setup to before_script (#1035 ) So that any failures during `hatchet ci:setup` cause the build to fail early, rather than try to proceed with running the Hatchet tests. @W-7929878@ [skip changelog]	2020-08-07 17:53:33 +01:00
Ed Morley	7b4f16145b	Add a configuration file for Git2Gus (#1034 ) This will allow for one-way sync of GitHub issues in this repository into our internal issues tracker, GUS. Issues are only synced when the specified GitHub label is added. In the future I may switch the chosen label to just be the standard `t: bug` type labels, but for now I'm choosing a separate label so that we have more control over what is synced.

Ed Morley	a165deadfb	Release v175 (#1032 )	2020-08-05 09:12:16 +01:00
Ed Morley	b64897a0b7	Fix inconsistent formatting in CHANGELOG.md (#1031 ) - Switches releases to always using H2 (`##`) rather than a mixture of H1s (meaning multiple H1s in the same document) and H2s. - Always refers to the versions as `vNNN` rather than sometimes without the `v` prefix. - Other formatting and typo fixes. @W-7905079@	2020-08-03 20:18:18 +01:00
Ed Morley	fc6698e597	Update pip to 20.1.1 (#1030 ) Updates pip from 20.0.2 to 20.1.1 for Python 2.7 and Python 3.5+: https://pip.pypa.io/en/stable/news/#id40 The version used for Python 3.4 remains unchanged at 19.1.1, since it's the last version of pip that supports it. Pip has been updated to 20.1.1 rather than the recently released 20.2, since the latter has a few regressions and even though these will be fixed shortly in 20.2.1, we should let the changes soak for longer before picking them up. The `PIP_NO_PYTHON_VERSION_WARNING` environment variable has been set (equivalent to passing `--no-python-version-warning`) to prevent the Python 2.7 EOL warnings added in pip 20.1 from spamming the build log: https://github.com/pypa/pip/blob/20.1.1/src/pip/_internal/cli/base_command.py#L139-L154 This was set via environment variable rather than CLI flag, since: * otherwise we'd have to pass it to every pip invocation * older pip (such as the 19.1.1 used by Python 3.4) doesn't support this option and would error out due to an unknown CLI flag being passed, unless we added conditional flags throughout.
