Idea: Capture expected Python version & artifact names in Pipfile.lock to improve error messages #295

ncoghlan · 2017-03-28T02:10:31Z

Working on a pipenv based development setup in oamg/leapp#8 we're finding it fairly easy for people to get into a situation where they accidentally create the venv with Python 2, but the lock file was generated with Python 3, so the hashes for pre-built wheel files may not match.

Example from oamg/leapp#8 (comment):

@shaded-enmity and I thought of two possible ways to make the resulting hash mismatch errors less confusing:

Record the implementation and version of Python used to generate the lock file in the lock file, since that may affect the pre-built wheel files that pip finds and downloads
For each locked artifact, record the filename in addition to the hash

For the first option, any hash mismatches would be preceded by a warning that the Python versions didn't match so the lock file may need to be regenerated.

For the second, if a hash mismatch was found, it would be reported as a filename mismatch first, and only reported as a hash mismatch if the filenames matched.

The text was updated successfully, but these errors were encountered:

This is also somewhat related to https://github.com/kennethreitz/pipenv/issues/236 (where pipenv install still defaults to Python 2, even if the lock file was generated on Python 3), as well as to https://github.com/kennethreitz/pipenv/issues/286 (which requests the ability to set the default Python version in Pipfile, which will then need to be passed through to Pipfile.lock somehow)

Hey @ncoghlan, thanks for checking in on this! #236 seems to be an issue with click not passing the option properly, rather than a misspecification of --two vs --three. #286 does seem in line with your first suggested approach though.

Kenneth and I spent a fair amount of time discussing hashes a few weeks ago and arrived at the recent --no-hashes and --ignore-hashes options. I'm, personally, becoming less convinced that the individual file hashing is worth the headache it creates on cross systems.

I am definitely open to ideas that will make the current experience better but here's the pain points I'm seeing in the suggestions provided.

Record the implementation and version of Python used to generate the lock file in the lock file, since that may affect the pre-built wheel files that pip finds and downloads

This does allow us to provide a more explicit message to the user in the event of hash conflict, which is nice. It would however restrict the user to only using a given lockfile on one platform and version, which is what we've been trying to avoid. We could use these fields only for the error message, but I'm betting people who are going to struggle with the "Hash Conflict" message won't have taken the time to add the requires properties. This is mostly conjecture at this point, but my gut feeling is the value add here will be minimal.

For each locked artifact, record the filename in addition to the hash

I could get on board with this one but it has the same problem as above where we're now bound to the wheel from platform X or version X. This defeats the point of a "universal" lockfile. I also can't seem to find anything in pip's documentation for the download command that would allow us to specify the exact file we want. Without that interface, I'm not sure the filename will give us much help.

Please let me know if you have further thoughts on this though. As I said above, this is design needs some help so the more ideas we have floating around on it, the better.

ncoghlan · 2017-03-29T02:51:55Z

Of the two suggestions, with the current "single universal lock file" structure, the one I'd recommend is to track the filename that the hash belongs to. When pip picks up a pre-built non-universal wheel, any environment mismatch is going to cause a hash conflict anyway, and having the filenames available will make for significantly more meaningful error messages.

However, I think a more important outcome of that approach would be the fact that tracking the filenames creates the opportunity to switch to a multi-level lockfile scheme, where you take the hashes out of the platform independent version lockfile entirely and move them to a separate environment specific artifact manifest. That is:

Pipfile: the hand-edited file that rules out dependency versions that are known not to work
Pipfile.lock: only locks the versions of the dependencies, not the specific downloaded artifacts
Pipfile.<PEP 425 compatibilty tag>.artifacts: expected artifact filenames and hashes

When pipenv locks an environment, it would then generate the artifact manifest based on the most specific binary compatibility tag present in the downloaded artifacts. So if a project only had dependencies on source distributions and pure Python wheel files (or if the --no-binary :all: option was passed to pip), you'd get manifests like:

Pipfile.py2-none-any.artifacts
Pipfile.py3-none-any.artifacts

Depending on whether it was Python 2 or Python 3 that was used to generate Pipfile.lock.

While if it had binary dependencies (as with the cffi example above) you might get:

Pipfile.cp36-cp36m-linux_x86_64.artifacts

pipenv install would then ignore any artifact manifest where the compatibility tags didn't match, as well as any that had been generated from a different version of Pipfile.lock (which could be tracked by storing a hash of Pipfile.lock as one of the fields in the manifest files)

Actually taking that second step of splitting out the artifact manifest from the version lock files would involve talking to @dstufft et al about moving pip's compatibility tag handling and wheel filename parsing out of pip itself and into the packaging utility library, but that's a desirable refactoring anyway.

Such a model then only fails in the presence of environment markers that result in Pipfile.lock getting different dependency lists based on which version of Python and which platform are used to do the install, and even that could potentially be handled at some point in the future by allowing for optional compatibility tags in lock files as well.

@nateprewitt Thinking about this a bit more, I can see a third way, which I think is a bit crazy, but I can't really tell if there's something really wrong with it, besides weird gut feeling.

Assumption: the main use-case of the hashes in the lock file is making sure that the content of the package that I'm pulling right now matches the package author WAS using during development. This can alone provide nice way to asynchronously verify integrity of the given resource.

Now let's try changing the highlighted WAS above into WAS OR WOULD HAD BEEN, and instead of recording a digest of single (package, version, environment) tuple record digests for all (package, version, *) matching tuples. So the format would look like:

"mydep": {
   "hashes": [
        "sha256:d8b24664561d0d34ddfaec54636d502d7cea6e29c3eaf68f3df6180863e2166e",
        "sha256:d232509fefcfcdb9a331f37e9c9dc20441019ad927c7d2176cf18ed5da0ba097",
    ],
    "version": ">=1.0.0"
}

Ideally we'd combine the digests with filenames as @ncoghlan suggested, so that we are able to figure out all well-known names we're accounting for.
It's not entirely bulletproof:

Package author publishes 3 different wheels of packageX==1.0.0
Package consumer creates a Pipfile.lock with packageX==1.0.0
Package author publishes 1 additional wheel of packageX==1.0.0

Security wise I think that checking multiple digests is OK, as there's a strong true/false relation in that we either trust {Digest function} or we don't.
This also fully depends on being able to figure out all the digests remotely from a Pip repository (so that we don't have to download all the artifacts only to digest them) - which may not fit well in the entire threat model, but is well aligned with my original assumption above.

It's not a perfect solution, but it fits the universality bill pretty nicely.

kennethreitz · 2017-09-05T22:13:38Z

For the record, pipenv moved away from --hashes mode being default, for this reason.

kennethreitz · 2017-09-05T22:14:22Z

Question is — how do we get those digests? is there a pypi api for them?

kennethreitz · 2017-09-05T22:14:40Z

If so, that'd make $ pipenv lock --hashes much faster.

kennethreitz · 2017-09-06T05:46:21Z

Going to tackle the first proposal:

Record the implementation and version of Python used to generate the lock file in the lock file, since that may affect the pre-built wheel files that pip finds and downloads

I has an idea.

Nice! How would you feel about something like environment-markers as the key name, rather than embedding the PEP number?

shaded-enmity · 2017-09-06T14:58:34Z

@kennethreitz AFAICT pypi.python.org currently provides only md5 digests but pypi.org also provides sha256 digests - https://pypi.org/pypi/pipenv/json

kennethreitz · 2017-09-06T16:23:07Z

@ncoghlan maybe host-environment-markers? I want to make it obvious that it's from the host that generated the file...

kennethreitz · 2017-09-06T16:26:06Z

Updated to host-environment-markers.

kennethreitz · 2017-09-06T16:51:09Z

@shaded-enmity excellent, i'll look into using that — that would vastly improve our lock times for --hashes, and allow us to provide multiple hashes for different systems (e.g. all hashes for a given release).

ncoghlan · 2017-09-06T23:07:20Z

@kennethreitz Heh, I initially had "host-environment-markers or environment-markers" as my suggestion, and then simplified it to only the latter. +1 for the more explicit version :)

kennethreitz · 2017-09-06T23:27:02Z

This is now released!

erinxocon · 2017-09-07T02:22:32Z

Closing issue as complete. Comment if you experience issues.

kennethreitz · 2017-09-07T02:30:08Z

Well, only partially. I think we have a ways to go still.

kennethreitz · 2017-09-07T15:48:58Z

So much progress! Being included in the next release. Thanks so much for your feedback, and the push to do this!

kennethreitz · 2017-09-07T16:04:38Z

Going to make --hashes default again!

kennethreitz · 2017-09-07T16:19:06Z

It's so fast!

kennethreitz · 2017-09-07T16:19:57Z

v6.0.0 released, which includes hashes for all editions of each given release. 💫✨🍰✨💫

It is also on by default, and can't be turned off (at least, yet). I don't foresee anyone wanting to turn it off, it works so well.

Now, this issue can be closed, successfully.

Thanks again!

kennethreitz · 2017-09-07T16:23:07Z

Gah, there's a bug. I'll fix it.

kennethreitz · 2017-09-07T16:25:22Z

Fixed!
