Lineage branches / lineage stack overflow [RESOLVED]

@zopyx it looks like your branch has been merged to master, so can we delete the branch now? Also, any reason why we shouldn't update the classifier to reflect that it works with Plone 5.2?

I'm looking to see if lineage works with Plone 5.2 on Python 3.

https://github.com/collective/collective.lineage/tree/python3-ajung

My mistake: you already did update the classifiers for both Plone 5.2 and Python 3.6/3.7

It looks then that all that is missing is the release of 2.3 to PyPI, correct?

There is even an issue for a new release^^

I'm getting stack overflows when adding pages or collections to a subsite, using the master branch. Will create an issue.

Hm, this is not behaving consistently... will check in a new build

It crashes the same way in a brand new vagrant (Plone 5.2, Python 3.7.3, Ubuntu 18.04.3 LTS)

<string>:387: DeprecationWarning: Using len() is deprecated. Use the `length` attribute for the size of the current page, which is what we return now. Use the `sequence_length` attribute for the size of the entire sequence.
Fatal Python error: Cannot recover from stack overflow.

It crashes the same way in a brand new vagrant (Plone 5.2, Python 3.7.3, Ubuntu 18.04.3 LTS)

:387: DeprecationWarning: Using len() is deprecated. Use the length attribute for the size of the current page, which is what we return now. Use the sequence_length attribute for the size of the entire sequence.
Fatal Python error: Cannot recover from stack overflow.
...
Apparently, we have an infinite call look here.
In this case, it apparently lets overflow the C runtime stack
(rather than tiggers Python's "MaximalRecursionExceeded" exception)
which causes the fatal error.

The loop seems to be composed of:

  • something looks up a (local persistent) utility, found
    by five.localsitemanager
    (five/localsitemanager/registry.py", line 60 in _uncached_lookup).
    localsitemanager wraps the utility

  • Because for the lineage case, current_site != registry_site,
    localsitemanager calls _recurse_to_site(current_site, registry_site)
    (five/localsitemanager/registry.py", line 159 in _wrap)

    This is the place where the "lineage" and "non lineage" cases
    differ

  • _recurse_to_site calls
    (via five/localsitemanager/utils.py", line 15 in get_parent)
    plone/dexterity/content.py", line 127 in get
    which indirectly (via
    plone/synchronize/decorator.py", line 9 in synchronized_function
    plone/dexterity/schema.py", line 58 in decorator
    zope/component/_api.py", line 157 in queryUtility)
    looks up a (local persistent) utility (found by five.localsitemanager).

Thus, while the problem pops up for lineage, it is not a lineage problem.
It can occur whenever current_site != registry_site, i.e.
whenever the Plone portal object it not the only relevant site in
the Plone portal. However, caching may hide the problem and may
let it occur (apparently) non deterministically.

In my view, the problem can be blamed either on
five.localsitemanager.LocalSiteManager._wrap
or plone.dexterity.content.FTIAwareSpecification.__get__ - in both
cases for insufficient handling of recursive use.

plone.dexterity.content.FTIAwareSpecification.__get__ seems
to be aware of problems caused by its recursive use.
Unfortunately, it sets up recursion monitoring only some lines after
line 127 (which introduces the recursion in our case).
Maybe, the easiest workaround would be to extend recursion monitoring
in __get__ to cover the current recursion.

The issue is described here: https://github.com/plone/plone.dexterity/pull/107
After that first attempt of solving the issue I also tested https://github.com/plone/plone.dexterity/pull/108
But I think https://github.com/plone/plone.dexterity/pull/114 make the previous PRs obsolete.

So I would check if using plone.dexterity master fixes the issue.

@alert called it! And @rpatterson created a test to confirm the fix, which has been merged into dexterity

:heart:

The fix is to pin plone.dexterity to 2.9.2
