Do not resolve all dependencies on add

[apietrzaklea]

Hey,

Right now, when I want to update/add one dependency I can see that PDM goes through all deps and tries to resolve everything once again.

Is there an option to skip that slow resolution?

What I mean is:

I have my packages:

    "sqlalchemy[asyncio]",
    "sqlalchemy-utils>=0.41.2",
    "asyncpg>=0.29.0",
    "psycopg2>=2.9.9",
    "cloud-sql-python-connector>=1.9.2",
    "alembic>=1.13.1",
    "google-cloud-tasks>=2.17.0",
    "google-cloud-pubsub>=2.27.1",
    "protobuf==4.25.3",

And then I want to add my private beta package:

pdm add my-private-package==0.1.0b10

And then I'm seeing that PDM tries to resolve packages not related no newly installed one:
pdm.termui: Adding requirement SQLAlchemy>=1.4.0(from alembic 1.15.1)

Ok, so then I want to install 1.0.0 version of the same package:
pdm add my-private-package==1.0.0

And PDM goes once again with checking all dependencies even when 1.0.0 requirements haven't changed since 0.1.0b10

Any reason to make so many checks when currently installed deps are already installed or is there a way to skip those checks somehow? To be honest it takes some time to resolve all of that right now.

You are on the right track, but in reality, you must consider this situation.

For example, flask depends on werkzeug, and if you run pdm add werkzeug, you must consider whether it will conflict with the existing flask version.

But I admit that this method is somewhat brute and not very smart. so it brings performance penalty

[monchin]

How about organize a dependency-version-range table at the first time, e.g., when you first pdm add "flask>=2.0,<3.0", the table should be like

{
    "flask": {
        "requires-python": ">=3.8",
        "version-range": ">=2.0, <3.0",
       "groups": ["default"]
    },
    "werkzeug": {       
        "requires-python": ">=3.9",
        "version-range": ">=3.0",
        "groups": ["default"]
    }
}

and when new package needs to be added, we directly look up the table. For example you input pdm add "werkzeug>=3.1", then from the table we know it's good, and all we need to do is to change the table to "werkzeug":{"version-range": ">=3.1"} and change the lock file.

@frostming I do not agree with your explanation.

See, I have library in version 0.240.0 and now I want to install the same library with command: pdm add my-lib which is 0.255.0. Most important thing is difference betweent those two versions which is code and version, no deps have been changed.

So let's install it and see output of PDM:

λ pdm add my-lib --verbose

STATUS: Resolving packages from lockfile...
Synchronizing working set with resolved packages: 0 to add, 1 to update, 0 to remove

So what happened here is weird. Because dependecies of my_library are the same, PDM should only check libraries directly affected by updated one and as nothing wrong happened here (no version mismatch), should end the update. But as we can see in logs, PDM did much more verification which was not needed.

[apietrzaklea]

@frostming I read the code and I understand that the current architecture does not allow for easy optimizations. As I see, the Resolver always works on all dependencies and based on the solution, a decision is made whether something should be removed or not.

But your words are correct, this solution is quite brutal and slow. The Resolver does not know which dependency has been changed, it gets the whole list and tries to update them all. Due to this, PDM does a lot of unnecessary work when installing dependencies, which makes pdm add more time-consuming for each new dependency.

Based on this, I think that the Resolver should know what is happening, so it would be possible to introduce optimizations to not touch dependencies that are already satisfied.
