Eventhough our current pattern is not the most secure, we have no other
choice for now that to use such insecure patterns.

In https://erp5js.nexedi.net/#/bug_module/20210819-20614EE we track possible
improvements to this situation.

This new version has a dependency to libsecret

Also adjust dependencies to the ones from https://github.com/eclipse-theia/theia/blob/v1.16.0/examples/browser/package.json
except api-samples which is not useful.

The resiliency pull-backup-server status feed file `pbs-status-rss`
is generated by a cron running every 5 minutes. But there is a promise
that requires it to check the notifier status, meaning instanciation
fails until this file is available.

To allow the promise to succeed immediately, we generate the
feed a first time directly from buildout.

Follow-up for commit 98e7a29a (component/trafficserver: Version up to
9.0.2).

Drop patch from pull-request 7577, as it has since been merged upstream.

Zodburi 2.5.0 added support for demo: URI scheme:
https://github.com/Pylons/zodburi/blob/master/CHANGES.rst#250-2021-05-12

- due to a thinko in c170fe3e (ZODB: Provide ZODB4-wc2 which backports MVCC approach from ZODB5)
  4-wc2 revision was set on a ZEO(egg) section instead of ZEO(repository)
  section. As the result it was ZEO4 - not ZEO4-wc2 - that was installed.

  This was leading to hangs in tests with wcfs waiting for ZODB server to
  update it after a commit, but no notification was coming from ZEO at all.

  For the refrence: the reason ZEO4-wc2 exists at all is the backport patches
  that teach ZEO to send invalidations even on empty transactions
  (nexedi/ZEO@bf80d23d), and to include
  just-created objects into invalidations as well (nexedi/ZEO@f2fae122).
  Those changes are needed for WCFS to be always notificated on every
  transaction and with full set of changed objects.

- there was a typo: it was `revisions` instead of `revision`.

-> Fix both issues. Now it is ZEO4-wc2 that is installed for real when `ZODB.major = 4-wc2`.

The promise is commented out because it fails inside a test suite
due to port conflicts with the testnode of the test suite.

`srv/testnode/abc/inst/test0-0`  -> `t/abc/i/0`

Replace `softwaretype` recipe with `switch-softwaretype`

This is similar to d67f382f (wendelin.core: Fix test build 2)

Always reference to in-tree eggs via ${<name>:egg} instead of just name. This fixes e.g. the following build failure:

    Installing wendelin.core-python.
    While:
      Installing wendelin.core-python.
      Base installation request: 'wendelin.core[test]', 'pygolang[pyx.build]', 'neoppod[tests]', 'ZEO[test]'
      Getting distribution for 'ZEO[test]'.
    Error: Picked: ZEO = 5.2.3

Not sure why it worked before.

Neoppod is a bit special - leave it as is for now.

This teaches nxdtest to detect leaked processes and to clean them up
automatically instead of letting tests stuck because of them. See
nexedi/nxdtest@0ad45a9c and
nexedi/nxdtest!9 for details.

New dependencies of nxdtest are:

- psutil (already covered by stack/slapos.cfg),
- pytest-timeout, and
- setproctitle

These comments are not updated automatically and very hard to update manually,
so it's better not to have them.
