Since c170fe3e (ZODB: Provide ZODB4-wc2 which backports MVCC approach from
ZODB5) we have a custom version of ZODB4 with backports from ZODB5 so that
wendelin.core can work in environments where we still use ZODB4.

In 2022 this test got broken after SlapOS transitioned to use python3 by
default and fixed in 5cb11e9e (component/ZODB: keep running the test on
python3). Then fixed in 2024 again in e742508b (! component/openssl: add
OpenSSL-3.0.13, still using OpenSSL-1.1 for python 2.).

However as of today building this test fails with

    slapos.rebootstrap:
    ************ REBOOTSTRAP: IMPORTANT NOTICE ************

    Buildout will be restarted automatically to have this change applied.

The problem here is that even though we use py2 for the software, the used
version of setuptools is py3 only and so it breaks.

This problem was already cared in f5b80301 (Downgrade pip, wheel and setuptools
in python2 SRs), but that commit missed to update test-zodb4-wc2.cfg .

-> Fix that.

After this patch the build of component/ZODB/test-zodb4-wc2.cfg becomes
recovered in the sense that it passes further than rebootstrap, but breaks at
the build of persistent / BTrees eggs. We will fix this in the next patch.

This reverts commit 552a9854.

This reverts commit 69d7b336.

Fixed version.

slapos.core and slapos.cookbook with fixed package release.

Including changes:

 * librecipe: stop calling getInstanceParameterDict by default
 * slapos.cookbook: Fix publish_failsafe

There is no reason to have so many empty lines, as other tools can have
troubles with processing it.

Do not return installed files in order to avoid endless Uninstall/Install of
the part and instead use the uninstall hook to handle the file when part is
uinstalled.

Also re-install during update if there was a problem with publishing during
install; note that checking for file presence on each update is very fast, so
the speed gain is preserved.

Call it only on demand, to get rid of useless http queries

A new version of zodburi has been released [1] that
removes Python2 compatibility shims [2] and is therefore
needed to successfully run 'wendelin.core' tests with python3 [3].

Suggested by @kirr.

When there is not a nobody user (for example inside Docker), the
tests TestAmbientCaps and TestAmbientCapsUserns should be skipped
instead of failing.

This has been patched upstream in
https://github.com/golang/go/commit/1959703dddffef61760d5d4fdedc4df8d2d73438
and we use here that patch.

    The `zodbpickle` egg does not have a version pin and `allow-picked-versions = false`.

    To resolve this, add

        zodbpickle = 4.2

    to the [versions] section,

    OR set `allow-picked-versions = true`.

This reverts commit 95b1d7df as
testnodes were upgraded.

See merge request nexedi/slapos!1737

Save HTTP requests to the registry and token manager logs in dedicated
log files and correctly logrotate them.

Also use a newer version of slapos.cookbook to properly revoke re6st
certificate when the slapos shared instance is destroyed.

Patch submitted here:
https://github.com/zopefoundation/ZODB/pull/403

We backport it in SlapOS directly as the branch 5.8 is not being
developed anymore.

This partially reverts f834a06f.

This shebang was causing issues with testnodes. See
f834a06f (comment 228158)

This is a fixup of d2d0d49e.
