      Products.CMFActivity.Activity.SQLBase: Drop "FOR UPDATE". · 89aa2a6b
      Vincent Pelletier authored
      This SELECT option was added when the UPDATE query was split into a
      SELECT + UPDATE query pair, in order to try to avoid deadlocks in mariadb.

            Work around poor UPDATE use of index.
      That was not completely successful, and another attempt was since made,
      which further ipmproved the situation:

            CMFActivity.Activity.SQLBase: Reduce the number of deadlocks
      
      This change made the "FOR UPDATE" option obsolete: there should be
      virtually no parallelism between the SELECT and UPDATE queries.
      By which I mean only 3rd-party accesses (like an admin on a mysql console)
      would bypass the SQL lock, causing index-update-level locking issues.
      
      Checking now, I see that removing "FOR UPDATE" on the "node>0" query makes
      that query (with LIMIT 30) run about 5 times faster:
      With FOR UPDATE:    0.509s
      Without FOR UPDATE: 0.090s
      This difference is enough to cause significant activity starvation on a
      63-processing-nodes cluster where such activities run in about 1s, just
      because of the amount of contention on the SQL lock, itself because of the
      duration of every execution of this query.
      
      So remove this now-redundant option.
      
      It is expected that this will improve activity processing performance in
      general, beyond just the starvation issue which led to this discovery.

      Folder: fix objectValues(portal_type=...). · 48cfa07a
      Kazuhiko Shiozaki authored
      For example, Web Section can contain a Script (Python) to set Access
      Rule, but the parent section's objectValues(portal_type='Web Section')
      should not include such object.

      Products.CMFActivity: Fix poor performance with many family-bound activities · 62af8254
      Vincent Pelletier authored
      When there are many simultaneously-pending activities attached to any
      processing node family, the
        node>=0
      subquery becomes dominant (taking hundreds of time longer than the other
      subqueries). As a consequence, this starves processing nodes of activities
      and increases the CPU needs of the mariadb process hosting the activity
      tables.
      So, move this subquery out of the regular codepath, and only run it if no
      other subquery found any activity:
      - there is no activity preferentially targeting the current node
      - there is no activity bound to any of the current node's families
      - there is no activity without any node preference at all
      Also, simplify the content of that subquery: the effective priority can
      only be 3 * priority + 1 when this query is run, and node=0 rows can be
      excluded (they should not exist in the current database view).
      Also, factorise the logic producing "node=processing_node" and
      "node IN node_set" subqueries, for simplicity. In turn, this makes all
      family-dependent subqueries use a simple equality test, ensuring a stable
      query plan independently from the number of families the current node is
      member of.
      Also, use "UNION ALL" always, as now:
      - all subqueries have stritly distinct result sets
      - as per mariadb documentation, "UNION [DISTINCT] applies to all UNIONs
        on the left", so the original comment about where ALL is used was
        incorrect in assuming it was improving the effective query performance
      Also, line-split SQL queries as visible in the python source to be more
      readable, without effect on the produced SQL.
      Also, line-split a few non-trivial python expression to make their
      internal structure immediately apparent.
      
      Another effect of this change this change is to reduce activity theft
      (activities to be preferentially executed by one node being executed by
      another), potentially improving object cache hit-rate and hence decreasing
      I/O pressure on the ZODB.

      patches: add a compatibility patch for `zope_quick_start` · 4c8d9ea8
      Jérome Perrin authored
      `zope_quick_start` was a dtml that was removed in Zope commit c8e4cd5ca
      (Simplify control panel objects and actually make them non-persistent.,
      2016-08-14), but it is referenced in /index_html page template, which
      contains:
      
          <tal:text tal:replace="structure context/zope_quick_start" />
      
      As a result, rendering / is an error page because of KeyError: 'zope_quick_start'
      
      In SlapOS setup, we are using / in an haproxy health check, so the
      health check fail and zope is marked as down and haproxy does not send
      requests to backend.
      
      We could have an upgrader constraint to repair this page template, but
      because of this, zope is unreachable through haproxy, so it's easier to
      ressort to monkey patching.

      ERP5Catalog: Fix UnicodeDecodeError on non ascii catalog search when the inituser name is unicode · 0cfe6090

      xhtml_style: don't set content type header if already set · 3c8fcd51
      Jérome Perrin authored
      This is necessary on Zope4 because the error page is executed even if
      the response already has a locked body - and in this case we don't
      want to override the content-type header that might also have been set.
      
      One user of this is Base_redirect from erp5_hal_json_style, when
      abort_transaction is True, in that case it sets a body in json, a
      content type header of application/json and then raise a redirect so
      that the transaction is not commited. This fixes a problem visible on
      Zope4 with erp5_bank_reconciliation_renderjs_ui_test:testFunctionalRJSBankReconciliationAction
