* SEARCH-2802: Filter HTTP requests (now "none" and "secret" communication methods are available) from X509 Web Filter.
* SEARCH-2802: HttpClientFactory (for Repository and Search Services clients) support for Shared Secret communication.
* SEARCH-2802: Fix HttpClientFactory base unit tests.
Re enabling changes disabled in ACS-936 we can see deadlock in asynchronouslyRefreshedCacheThreadPool (AbstractAsynchronouslyRefreshedCache).
There should be no reason to be calling the dictionary destroy method before the doCall() finishes...and it is the use of the destroy method that carries the risk of deadlock.
Proposed fix: the liveLock is used for the doCall() method, this will stop deadlock from external calls to dictionary destroy() while doCall is in progress.
Removed invalidating cache fix (e.g. fix the issue where cluster nodes could have null values and other nodes had default value… so no properly invalidated on node startup). This fix was moved in ClusteringBootstrap as the initial one was causing issues.
* MNT-20775 : rest api /deleted-nodes with maxitems parameter take longer when there are more items in the trash can
Based on offset and limit, returns only the required results from database
Added count query for ArchivedNodes
* ACS-953 Unable to upgrade from ACS-7.0-M1 or ACS-7.0-M2 to ACS-7.0-A12
Now that we create internal releases of the form M.m.r-M9 (milestone), M.m.r-A9 (alpha) and M.m.r-RC9 (release candidate) during development and testing, we need to ensure we can upgrade from any of these to any other, as they may occur in any order and also to the final external release M.m.r. We also will allow a change from the final release back to an internal one for regression testing. The code within ModuleComponentHelper which calls this method, checks if it is the same version (0) and then if it is downgrading (> 0), so if they share the same M.m.r part matches AND is one of these formats, we return <0.
