2020 resolver does not consider hashes in the constraints file #8792

A confirmed bug or unintended behavior

We completely overlooked this 🙂 Constraints went through a minor re-design in the new resolver, so there are a few decisions we need to make:
|

Interesting, I did not expect that hashes in the constraints file wouldn't be processed, so I was wrong about the cause of my issue. I've made my example simpler in a branch (https://github.com/jwhitlock/pip-resolver-demo/tree/just-constraints). I've added a note to my original bug, and plan to change the title, but I haven't re-written my original bug entirely. My mental model of a constraints file is that it is the requirements of the requirements that I care about. For example, I use This separation supports the way I approach package updates:
The other nice feature of constraints is that, if a project requirement stopped requiring them, then they didn't get installed. Otherwise, it seems like I could solve my issue by changing With that preamble, my answers are:
I think other people's legit use would be a and a so that works and securely installs the listed packages. |

@pfmoore Do you have concerns with (re?)introducing this behaviour, for this use-case? |
|
tl;dr; I feel that we should be cautious, but I don't have a strong objection. I wouldn't describe the new resolver changes as a "minor redesign" - I think we did a fairly comprehensive overhaul and stripped constraints files down to being purely a way to specify global (version) limits for packages. That gave us a very specific behaviour, that translates well to how pip decides which version to install (don't even consider versions that don't match the limits in the constraint file). I'm fine with adding extra functionality to constraint files that is in the same vein - removing certain candidates from consideration up front. As @uranusjr says, hashes can be viewed in this way, and so I feel that it's a reasonable extension. However, that logic does mean that IMO the only reasonable interpretation of the case when hashes are in both constraints and requirements is "intersection" - pip never considers anything that doesn't match the constraints, so if a requirement has a conflicting hash, pip will see nothing and hence will fail. I'd be unhappy with "requirements override" or "union" because they don't fit that model.
That's not how I viewed them when I designed the new implementation. As I said above, the intended interpretation is that constraints limit what candidates pip sees. Most of the time, I don't expect there to be much difference in the viewpoints (which has positive and negative aspects - we won't conflict with people's expectations, which is good, but people may want to push constraints in a direction we didn't intend, which is less so...) |
|
Some additional context: pip currently merges hash lists (i.e. a union operation) if a requirement is specified multiple times. So this has the same effect as The ordering of hashes does not matter, nor whether the line is a constraint or requirement. So if we’re going to change the constraint file’s behaviour, we should probably also change the merge logic in requirements.txt as well. But the problem is, the merge is currently done during the parsing stage, and shared between both resolvers. This can be tricky to change 😥 |
|
Ah. Yes, that will be tricky. But IMO having a consistent model is the important thing (something pip has traditionally not been very good at doing 🙁) so we should either come up with a different model for constraints that makes union the "natural" interpretation¹, or bite the bullet and make the tricky change. Personally, I like the current model as it's very easy to explain. ¹ And, of course, review the existing constraints code to make sure it conforms to the changed model 🤷 |
|
Where does the merging occur? My understanding was that we were handling the hash-checking-related rejections in Provider.find_matches (and, finally, in a loop in whatever the relevant method on |

I did this too, and I was wondering whether I was missing something. :)

Intersection sounds the most natural to me too. Just one question: what if we have |
|
Do you have a real world use case? If you're asking in a purely theoretical sense, then I'd say:
I'd say that the result should be that only versions of foo with the given hash can be selected (i.e., intersection) but it wouldn't trigger full hash checking mode, because hashes in constraint files don't do that. But I don't really like that behaviour, because it would encourage people to use constraints for "only hash check one project" mode. An alternative would be to disallow hashes in constraints files unless hash checking mode is in force (which would mean that a constraint file with hashes in it couldn't be used with requirements that omit hashes). It's hard to say which is best without a proper use case, though. The bigger question is whether constraints files can even include some projects with hashes and others without. Hash checking is supposed to be all-or-nothing, and having constraints files that could add hashes to some projects but not others could be very confusing. Maybe what we should really be doing is saying that hashes in constraint files should also be all-or-nothing, and therefore that if a constraint file contains hashes, all projects in that constraint file must have hashes, and using the constraint file triggers hash checking mode, meaning that any requirements not limited by a constraint must have a hash specified in the requirements. But all of this is guessing. We don't have a good enough conceptual model of has checking (IMO - or if we do, it's not documented well enough) and we don't have enough real use cases to infer what rules would be useful. |
Not really. The current hash checking mode is not practical for my use cases because it does not work with VCS URLs and it disables the wheel cache. So I'm probing the corner cases to try to make myself a mental model of what would work and what not. And the model is not clear yet, for sure :) What could work is to say that when a constraint gets activated and we are in hash checking mode, that constraint must have hashes, just like other requirements. And then do the intersection. |
You would get Indeed there is a theoratical use case, but I’m happy to keep it as-is and not worry about it. |

@jwhitlock I think the fix to the issue is surfacing another different bug (that was not triggered previously since pip fails before hitting it). It would be best to track it in another issue. |

Update 1:
The issue was not the projects multiple requirements file, but instead the combinations of using hashes and a constraints files. The current resolver uses hashes on a requirement in a constraints file, while the 2020 resolver ignores them, and fails to install because they do not have hashes. The description below describes the more complex version.
Update 2:
Merged in the changes, so the default branch of pip-resolver-demo describes the simpler version, and includes the
django.txt/django-versions.txtexample as well.What did you want to do?
Our requirements files include other files, as a way to only specify a requirement once for two different environments (development and building in ReadTheDocs.org):
default.txt:-c constraints.txt,-r docs.txt,-r shared.txtdocs.txt:-c constraints.txt,-r shared.txtshared.txt: Noneconstraints.txt: NoneAll of our requirements are specified with hashes, populated with hashin.
This works, without warnings, when installing with
pip install -r default.txtand pip 20.2.2.When installing with pip 20.2.2 or pip-20.3.dev0 (today's in-development version), this fails:
The
idna==2.10requirement is inconstraints.txt, with the sha256 hash.A similar error occurs when installing
docs.txt:Output
