Poetry update never finishes resolve and Poetry show --outdated hangs #832

amal-khailtash · 2019-01-24T15:15:24Z

I am on the latest Poetry version.
I have searched the issues of this repo and believe that this is not a duplicate.
If an exception occurs when executing a command, I executed it again in debug mode (-vvv option).
OS version and name: Oracle Linux Server 7.5

Issue

When I try to see the list of outdated dependencies (poetry show --outdated), poetry hangs. And "poetry updated" gets stuck on "Resolving dependencies" and incrementing time (166.8s).

Running with --vvv:

$ poetry -vvv show --outdated
Using virtualenv: .../.venv

For some reason, I found out that 'bit-vector = "0.42a0"' is causing this hang. Any of the following is the cause of the hang. I found this when I reported #824.

bit-vector = {version = "^0.42.0a0",allows-prereleases = true}
bit-vector = "0.42a0"

floer32 · 2019-04-08T07:01:08Z

I think it may have something to do with Poetry's use of cachecontrol (notice the mentions of cachecontrol and lockfile towards end of logs).

If you dig through Poetry's source you'll see there is a class PyPiRepository, with an __init__ parameter disable_cache=False by default. It seems like there is not currently a way to disable it through Poetry, and there doesn't appear to be (relevant) global config overrides for cachecontrol or lockfile ...

What you can do in the meantime is to delete the Poetry cache dir and try running again. At first I thought I was still having the issue, but after a bit it moved on. So it really was a filelock deadlock at first for me, and for some reason always getting back into the state upon trying again... but 🤷‍♂️ I guess it is something intermittent.

How to find your cache - well, check the Poetry configuration docs to see about the OS-specific defaults. And you can delete it by hand that way.

There is also poetry cache:clear (version >1 it becomes poetry cache clear syntax). Its CLI docs are not very clear yet but I believe the usage is poetry cache clear $POETRY_VERSION --all

bersace · 2019-06-04T13:51:43Z

@hangtwenty thanks for your point. I often hit outdated cache when i switch from one project to another. Uploading a new release of a libs in pypi doesn't invalidate poetry pypi cache.

nierob · 2019-11-20T10:37:36Z

I hit the same and I can confirm that running:
poetry cache:clear --all .
solves the problem

kivo360 · 2020-03-18T04:11:50Z

Has anybody solved this? My installation is stuck and cache clear states I don't have any cache.

cgungor · 2020-04-03T22:49:08Z

Has anybody solved this? My installation is stuck and cache clear states I don't have any cache.

Can you share your poetry update -vvv log?

joshorr · 2020-04-14T18:51:05Z

I've had Poetry take over 800 seconds before giving up [it was bascially never finishing]. I tried poetry 1.0.0, 1.0.5, 1.1.0a1 and had the same results. I also cleared the cache on each poetry version I tried, with the same problem still happening.

Here is the log:

Poetry never finishing update.txt

I've attached a poetry update -vvv log @cgungor that showcases the issue. Reading the log, it looks like it keeps trying older and older versions of botocore due to docutils = "<0.16" requirement in botocore. Earlier in the process it decided to use docutils 0.16 due to sphinx (2.4.4) depends on docutils (>=0.12). I don't know why it did not figure out that docutils(>=0.10,<0.16) is fine with docutils (=0.15.2).

So I tried adding this to my .toml file: docutils = "<0.16". I reran the update and it finished in a about 4.5 seconds. Here is the output of that run:

Pinned Dep, poetry finishing update.txt

So for now I'll have to keep docutils pinned <0.16 my self, but it would have been really nice for poetry to figure it out on it's own!

joshorr · 2020-04-14T19:48:37Z

Thinking about this more, I suppose it's normal for it to go back and try older versions. In this case, botocore has a lot of versions to go though. So it may be using a depth-first search? Perhaps it should be a breadth-first search? Perhaps it could try each older version of each dependency it needs to figure out a solution for before trying two-versions back?

joshorr · 2020-04-14T19:55:25Z

I also tried doing botocore = ">=1.15.39" in my .toml file instead, it only took an extra second to find a solution vs the docutils = "<0.16". I like this way better since I can leave it be long-term without having a problem [at least until botocore starts having a lot of versions after 1.15.39 and Poetry slows down too much again, which I can then update this to a later version].

I think this makes it do a depth-limited search on botocore, so it can stop searching for solutions that never work and try something else that will work faster.

Halkcyon · 2020-06-25T16:50:41Z

I ran into this issue trying to run an update today. Clearing the cache appears to have resolved it, but resolution of packages across multiple indeces is extremely slow. When scanning for a package, if found in the default index, it proceeds to scan the secondary indeces anyways (where I have three in all so each package install is taking around TEN seconds).

m-vdb · 2020-12-10T08:44:49Z

I ran into a similar issue today with poetry version 1.1.4. I was able to "solve" it by doing:

poetry cache clear --all .
rm poetry.lock
poetry install -vvv (for some reason, I ran it without the -vvv flag before and it kept hanging, at least with -vvv I see what's happening)
🤷🏻

Queuecumber · 2021-03-23T14:28:00Z

I just had this today and it looks like mine was stuck looping on the following:

   1: fact: sphinxcontrib-katex (0.6.1) depends on sphinx (>=1.6)
   1: selecting sphinxcontrib-katex (0.6.1)

I had literally hundreds of the above lines printing out before I finally killed it, not sure why that is causing it to get stuck

Queuecumber · 2021-03-23T14:46:48Z

I can confirm that this works on poetry 1.0.10 so it is a regression (ref: #3802)

issam-seghir · 2022-03-24T07:44:05Z

@m-vdb
I confirm that this works on Poetry version 1.1.13

mkniewallner · 2022-07-10T15:33:07Z

Closing this issue, because it's on a quite old version of Poetry, and poetry -vvv show --outdated works correctly on recent version.

For the "slowness" of the resolver, there's already a bunch of issues opened, the main one being #2094.

jankatins · 2022-10-20T16:51:38Z

Just FYI: I had a similar issue like the one above, with py-spy showing the following things:

 poetry add -G dev rich --verbose

Running poetry cache clear --all . after removing the lock file solved it for me (removing the lock file itself didn't change a thing, but no idea if the cache clearing alone would have solved it.).

AaronMoe · 2023-02-23T14:56:00Z

I'm having a similar issue, I tried the cache clear and then run poetry update -vvv log - but I can't find a log file. Also, if there's new information on the issue of poetry getting stuck I'd be happy to hear about it. If there's people active here I think I could also show the pyproject.toml
