Fixes#7988. As described there, the steps involved are:
1. Update our tests so they fail due to this problem.
2. Update the keys used in the tests so they pass with the new changes.
For 1, see a [failing travis run](https://travis-ci.com/github/certbot/certbot/jobs/340710511) with the included change. And for the full output to confirm that this is what is failing, see a [run on debian 10](https://github.com/certbot/certbot/files/4692350/debian_run_log.txt).
This PR adds `rsa4096_key.pem` and `rsa4096_cert.pem`, updates the `TLS-ALPN` test to use those keys in place of the 1024-bit versions, and fixes the README in that `testdata` folder with correct instructions to generate these files.
* export PIP_NO_BINARY in pip install subshell in test_sdists.sh
* set environment variable on the line that installs most packages
* Generate 4096-bit rsa key and cert, and fix README instructions to do so.
* Update TLS_ALPN test to use 4096-bit key instead of 1024-bit key.
* Update changelog
* Older versions of Python have an error when both VIRTUAL_NO_DOWNLOAD and PIP_NO_BINARY are set, so only apply the latter at the install phase.
* Add enum34 constraint manually, since rebuild_dependencies.py seems to be broken.
* only delete key if it exists
* Check OpenSSL version before trying to set PIP_NO_BINARY
* Add comment explaining why we only set PIP_NO_BINARY at the install step
* Add the content interface to Certbot

Fixes#7993
This PR uses `os.umask()` during `certbot.compat.filesystem.makedirs()` call to ensure that all directories, and not only the leaf one, have the provided `mode` when created. This ensures a safe and consistent behavior independently from the Python version, since the behavior of `os.makedirs` changed on that matter with Python 3.7.
* Implement logic to apply the same permission on all dirs created by makedirs
* Add a test
* Add comment

The error message from `python3 -m venv` when you don't have `python3-venv` installed is pretty good, but lets skip the failure and make sure it is installed the first time.
Related to #7649 since @joohoi needs a method to copy owner and permissions together from a source file to a destination file.
This PR creates the method `copy_ownership_and_mode()` in `certbot.compat.filesystem` module to achieve this goal. Its behavior is consistent across Linux and Windows in respect to the security model that have been defined for Certbot on Windows.
The method behaves globally the same than `copy_ownership_and_apply_mode`, but this time the permissions are extracted from the source file. For Windows it means that the DACL is copied from the source to the destination with the same content.
* Create copy_ownership_and_mode to copy both owner and mode from src to dst
* Update certbot/tests/compat/filesystem_test.py

`tox -e cover` fails for me on macOS. This is due to the differences in the code that is run when on Linux vs. other platforms in `certbot.util` and its tests. Diffing my local coverage with Travis, the only difference in lines missing test coverage is:
```
$ diff travis.txt local.txt
< certbot/certbot/util.py 238 24 90% 132-134, 210, 275-281, 318, 330-340, 347, 381-382
> certbot/certbot/util.py 239 34 86% 30, 132-134, 210, 275-281, 301, 305, 316-318, 330-340, 347, 367-373, 381-382
< certbot/tests/util_test.py 392 0 100%
> certbot/tests/util_test.py 375 26 93% 483-487, 492-502, 507-514, 548-550, 555-557
```
I think tests on `master` should not be failing locally for people.
While there would be other ways to fix this by adding `# pragma: no cover` lines or writing mocked out tests for other platforms, I personally just think dropping the minimum coverage one percentage point is fine at least for now.
Coming out of the conversation at #7863 in the linked Google Doc, we should always have at least 1 release between updating one of our plugins to stop using a deprecated acme/certbot API and removing it from acme/certbot. Doing this gives the plugin changes time to propagate rather than potentially having the plugin break because Certbot was updated before the plugin had made the necessary changes.
This comment here should help ensure this.
* Add pytest warnings warning.
* clarify comment
Fixes#7713.
As discussed in #7713, providing a Powershell script as hook for Certbot is not working currently. This is because hooks are run in a `cmd` environment, that recognizes only `.bat` files as valid scripts that can be run from their bare name on command line.
On the other hand, the Powershell both `.bat` and `.ps1` scripts as valid scripts.
This PR makes hooks command be executed by Powershell, instead of `cmd` as `Popen` does by default when `shell=true` is used. It also modifies the tests to handle this new environment, in particular in term of encoding (UTF-16-LE is the default one in Powershell).
* Run hooks in powershell on Windows
* Fix hook test
* Fallback to unittest.mock
* In fact, shell_cmd as a list of str could not work. Declare only str as acceptable input for shell_cmd.
* Added changelog
Despite this PR (only) being ~200 lines containing mostly code copied from another repo, there is a lot going on here. For the sake of making it both easier to review and to remember some of these things in the future by referring back to this PR, I've documented a lot of noteworthy things with section headers below. With that said, it's probably not necessary to read each section unless you're interested in that topic.
The most noteworthy thing for the reviewer is **this PR should be merged and not squashed** to preserve authorship. To merge this code, once we're happy with this PR, I'll probably open a new PR squashing any commits I make in response in review comments back into a single commit to try to keep history somewhat clean. To help prevent this PR from being accidentally squashed, I'm making this a draft PR for now.
### Git history of https://github.com/basak/certbot-snap-build
I think it is worth preserving the git history of https://github.com/basak/certbot-snap-build that this PR is based on in this repo to help us track why things were done a certain way. To do this while keeping our git history somewhat clean, I took the approach described at https://stackoverflow.com/questions/1425892/how-do-you-merge-two-git-repositories/21495718#21495718 to move all history of https://github.com/basak/certbot-snap-build into a `snap` directory. I then squashed all commits so that sequential commits from the same author are one commit. I probably could have reordered commits to try and squash things a little more, but I personally don't think it's worth the trouble. Finally, I merged this rewritten history into this branch of the Certbot repo.
The contents of the `snap` directory are identical to the current contents of https://github.com/basak/certbot-snap-build before my final commit in this PR which makes the changes to make things work in this repo.
### Travis stages
This is described in general at https://docs.travis-ci.com/user/build-stages/, but I don't think we should deploy the snap if any of our tests are failing. To accomplish this, I created a "Snap" stage that builds, tests, and deploys the snap which is only executed after a "Test" stage that contains all of our other tests. The "Snap" stage will not run until the "Test" stage completes successfully.
### snap/local
This directory is ignored by `snapcraft` which I think makes it a good place to store `snap` specific scripts like `build_and_install.sh`.
See https://bugs.launchpad.net/snapcraft/+bug/1792203 for more info.
### Why remove certbot-compatibility-test from apacheconftest toxenvs?
Because it's not used. In theory, it could go in its own PR, but it'll create merge conflicts with this one so I'd personally prefer to include this simple change in this PR as well.

* Remove legacy Store upload credentials
These have not been needed since 5d7969a.
* Work around dev part dependency failure case
Get pip to install certbot from its VCS repository directly during the
build of the nginx and apache plugin parts.
This works around issue #12 when it affects the interaction between the
apache or nginx plugin and certbot itself.
It does not work around the case where the same problem occurs in the
interaction between certbot and acme. This looks harder to work around
because pip's VCS URL handling doesn't appear to include a facility to
install from a subdirectory of a git repository and this is where the
acme source is located.
* Switch to using lxd for the snapcraft run
The Docker image is 16.04 only. Before we can switch to 18.04, we need
to remove Docker, which means using the snapcraft snap using Travis' new
snap support, and then using the lxd functionality in snapcraft so that
it is enabled to build in the appropriate environment.
* Switch build to use core 18
Fixes: #14
* Move constraints into a list
This seems to be a requirement either either newer snapcraft, snapcraft
in lxd or in the move to core18 (it isn't clear to me which). This fixes
the error:
Failed to load plugin: properties failed to load for certbot: The 'constraints' property does not match the required schema: '$SNAPCRAFT_PART_SRC/constraints.txt' is not of type 'array'
* version-script -> snapcraftctl set-version
The use of version-script seems to break with either newer snapcraft,
snapcraft with lxd or core18 (it's not clear to me which). The breakage
is related to "parts/certbot/src" not being found. This can be fixed
with $SNAPCRAFT_PART_SRC, but this doesn't seem to be defined at
"version-script time".
However https://snapcraft.io/docs/deprecation-notices/dn10 deprecates
the use of version-script, and if we convert to the recommended new way,
then we use override-pull instead and $SNAPCRAFT_PART_SRC is defined
there, so this conveniently fixes both problems at once.
* Do not explicitly install snapd
Since this is now handled by the Travis addon, we do not need to do it
explicitly.
* Add Travis notifications
* Adjust automatic snap deployment configuration
Travis now has a documented[1] "snap" provider and the previous
experimental mechanism seems to have stopped working, presumably because
it was deprecated in favour of this new mechanism.

* Always act directly on upstream master
I want to keep this always working, so move to master. We can
reintroduce upstream stable releases when we are ready for general use.
Closes: #5
That particular issue seems to no longer happen. Presumably something
changed in upstream git or in PyPI. If it happens again, hopefully I'll
have CI against upstream master up by then and I'll be able to pin it
down.
* Add empty Travis build
* Add Travis automatic snap edge publication
* Add integration test
This uses upstream's test suite from their source tree to check the
built snap to make sure it behaves as expected, before attempting upload
to the store.
* Point Augeas to its lens library
Augeas defaults to looking in /usr/share/augeas/lenses, which in a snap
isn't found at this path, but inside $SNAP. So set AUGEAS_LENS_LIB to
where the lenses can be found within the snap.
This fixes the Apache plugin that uses Augeas.
