GH-95707: Fix uses of `Py_TPFLAGS_MANAGED_DICT` by markshannon · Pull Request #95854 · python/cpython

markshannon · 2022-08-10T15:24:06Z

Allows Py_TPFLAGS_MANAGED_DICT to be directly used in builtin classes.
- Doesn't crash
- Inheritance works properly
Classes inheriting from variable sized classes (like int) can now used managed dictionaries
Fails fast for incorrect use of tp_dictoffset, by setting tp_dictoffset to -1 if Py_TPFLAGS_MANAGED_DICT is set.

The downside is that C extensions that perform their own version of _PyObject_GetDictPtr() are even more broken than they were in 3.11. Hopefully no one is doing this anymore.

Issue: Support the use of the managed pre-header in builtin classes. #95707

…is set.

…FLAGS_MANAGED_DICT set.

…1 if using managed dicts. Allows use of managed dict on subclasses of variable sized objects like tuple.

LGTM

I've left some comments to get clarification, but none of them should hold this up unless you think we've missed something.

⚠️⚠️⚠️ Buildbot failure ⚠️⚠️⚠️

Hi! The buildbot wasm32-emscripten node (dynamic linking) 3.x has failed when building commit 3ef3c63.

What do you need to do:

Don't panic.
Check the buildbot page in the devguide if you don't know what the buildbots are or how they work.
Go to the page of the buildbot that failed (https://buildbot.python.org/all/#builders/1056/builds/303) and take a look at the build logs.
Check if the failure is related to this commit (3ef3c63) or if it is a false positive.
If the failure is related to this commit, please, reflect that on the issue and make a new Pull Request with a fix.

You can take a look at the buildbot page here:

Note: switching to '3ef3c6306def489ba9115f0a8a57ab1e99795a5c'.

You are in 'detached HEAD' state. You can look around, make experimental
changes and commit them, and you can discard any commits you make in this
state without impacting any branches by switching back to a branch.

If you want to create a new branch to retain commits you create, you may
do so (now or later) by using -c with the switch command. Example:

  git switch -c <new-branch-name>

Or undo this operation with:

  git switch -

Turn off this advice by setting config variable advice.detachedHead to false

Note: switching to '3ef3c6306def489ba9115f0a8a57ab1e99795a5c'.

You are in 'detached HEAD' state. You can look around, make experimental
changes and commit them, and you can discard any commits you make in this
state without impacting any branches by switching back to a branch.

If you want to create a new branch to retain commits you create, you may
do so (now or later) by using -c with the switch command. Example:

  git switch -c <new-branch-name>

Or undo this operation with:

  git switch -

Turn off this advice by setting config variable advice.detachedHead to false

⚠️⚠️⚠️ Buildbot failure ⚠️⚠️⚠️

Hi! The buildbot wasm32-wasi 3.x has failed when building commit 3ef3c63.

What do you need to do:

Don't panic.
Check the buildbot page in the devguide if you don't know what the buildbots are or how they work.
Go to the page of the buildbot that failed (https://buildbot.python.org/all/#builders/1046/builds/383) and take a look at the build logs.
Check if the failure is related to this commit (3ef3c63) or if it is a false positive.
If the failure is related to this commit, please, reflect that on the issue and make a new Pull Request with a fix.

You can take a look at the buildbot page here:
