added zope2 compatibility, but nexedi/erp5@21f85a6f (comment 180420) noted
the given assumption isn't true, which is why fixup commit nexedi/erp5@7a2c616e was
added. But nexedi/erp5@21f85a6f (comment 184548) noted
that nexedi/erp5@7a2c616e missed one case,
which is why this fixup commit is added. Now everything should be ok.

Because these two plugins implement the refresh of the authentication
token (unlike the facebook plugin), we can use a longer cache here.
With the previous value of 1 day, when not using the site for more than
1 day, token would expire from cache and user have to authenticate again.
Because the scenario of "access is revoked from authorization server"
is handled by refreshing the access token, we can use a longer duration
here, so that user do not have to login again after not using for two
days.

After server restarts, mariadb uses an error 1927 which is mariadb
specific, with no corresponding constant in CR module when server
restart. This is the case at least with mariadb 10.3.38.

This fix the following problem:
 - start zope and use mariadb connection
 - restart mariadb
 - use mariadb connection again, see an error:
    Error Type: OperationalError
    Error Value: (1927, 'Connection was killed')

This change to treat 1927 as an error for which we can reconnect and
retry the query. Some other connectors do it, for example sqlalchemy in
https://github.com/sqlalchemy/sqlalchemy/issues/5493

This prevents tracebacks during shutdown:

Also rename the method because this is not longer *Z*server.

This waitress close() API is not public part of API, so we still ignore
the case where the server thread does not stop after 5 seconds. This
happens if some HTTP connections are still open at the end of test.

   This is expected that constraints can call getConstraintType() if they are filtered:

    return context.checkConsistency(fixit=1, filter={'constraint_type': 'post_upgrade'},)
  Module Products.ERP5Type.Core.Folder, line 1476, in checkConsistency
    error_list.extend(obj.fixConsistency(filter=filter, **kw))
  Module Products.ERP5Type.Base, line 2714, in fixConsistency
    return self.checkConsistency(fixit=True, filter=filter, **kw)

    error_list.extend(obj.fixConsistency(filter=filter, **kw))

   There is a missing "r" on the link, acording to apache documentation:

    Additionally you have to create symbolic links named hash-value.rN. And you should always make sure this directory contains the appropriate symbolic links.

    See: https://httpd.apache.org/docs/2.4/mod/mod_ssl.html

This reverts commit 89aa2a6b.
The assumption that FOR UPDATE was unnecessary is wrong: when SQLDict
reserves similar activities, it will race against these primo-reservations.
So this change actually opens the possibility for duplicate activity
reservation.
Revert this change until (hopefully) a better fix is implemented.

In case of network problems, the http requests made to google during
login may take too long and cause global unavailability of the ERP5
instance.

Today we saw in long request logs:

oauth2client does not expose an API to set a timeout, but it allows
passing a custom http instance where we can set a timeout.

On Zope2 this method does not exist and this caused a test failure

To write a pid file so that logrotate can send us signals. This is
still needed for neo storage for now.

See nexedi/slapos!1395

Loading ZConfig will initialize storage and generally might do things
that will cause messages to be emitted.
One actual problem is with neo storage, which configure root logger
when it's not already configured [1], this was causing all logged
messages to be logged in the console when using neo storage.

It is easy to see contents ordered by id by default in ERP5Site.

Protect data from human error. There are unbelievable mistakes. ERP5
is a place to store important data that must not be deleted easily.

Errors in getObject (typically, unauthorized) were hidden by another
error in finally block, because popRequest can only be called if
pushRequest was executed before.

The roles were missing

Thanks to Vincent Pelletier for his help on this bug fix.

also set hide_rows_on_no_search_criterion to force displaying the list
even without search, this is a report, we we always want to see records.

This is done on the process running test (by
ERP5TypeTestCaseRequestConnection) and when using timerserver loop (by
TimerServer which calls publish_module), but this was never set in
processing_node.

Before 3b874e49 (ERP5Type/tests: review requests in tests, 2023-04-19)
getRequest could find a request anyway, because the test pached
getRequest to find a request from the app, but after this change
executing activities in an instance running with runUnitTest without
test specified failed with:

    Module importlib, line 37, in import_module
      __import__(name)
    Module Products.ERP5Type.dynamic.component_package, line 412, in load_module
      return self.__load_module(fullname)
    Module Products.ERP5Type.dynamic.component_package, line 379, in __load_module

    Module _weakrefset, line 86, in add
      self.data.add(ref(item, self._remove))
  TypeError: cannot create weak reference to 'NoneType' object

( maybe we remove processing_node and use only timerserver, these two
methods are more or less equivalent for simple cases and timerserver is
closer to what a "real" zope does )
