  • ba63ba44   OPENDJ-1569 Persistent search on cn=changelog does not return updates ... Browse Dir » 
    Code was broken by the fix for OPENDJ-1541 Persistent search on cn=changelog can return duplicates.
This change introduced a search phase enum and initialized all searches to the "initial search" phase.
Current fix consist in directly initializing persistent searches with changesOnly=true to the "persistent search" phase.

    There is a mismatch between code before and after r10757.
This is affecting 2.6.x and 2.6.next OpenDJ servers communicating with each other.
Before r10757, serialized ModifyMsg included a zero separator after byte arrays, after r10757 it did not.
This change is introducing back the zero separator.

ModifyMsg.java:
In getBytes_V45(), appended the zero byte separator after byte arrays + adapted decodeBody_V4() code for it.

    Persistent searches are registered before initial search ends (which is correct).
Because a new change can be added to the changelog before the "initial search" phase is over, the "persistent search" phase can return this change before the "initial search" phase returns it later.

To avoid this problem, persistent searches is marked with an enum to mention which phase is being run. The phases are the following:
1. INITIAL: The "initial search" phase is running, the "persistent search" phase do not return any entry.
2. TRANSITIONING: The "initial search" phase has completed and blocks currently running "persistent search" phase while the former is verifying no new updates where persisted to the DB
3. PERSISTENT: The "initial search" phase is finished and completed the transition to the "persistent search" phase. The "persistent search" phase can return all entries.
For the change-number-based persistent searches, only the last changeNumber sent by the "initial search" phase is recorded. For cookie-based persistent searches, for each replica, the last CSN sent by the "initial search" phase is recorded.

Problem is that the transitioning phase has the potential to block the whole server if the client of the persistent search does not consume changes fast enough.
This will be addressed separately.


ChangelogBackend.java:
Added constants COOKIE_ATTACHMENT and ENTRY_SENDER_ATTACHMENT.
Added cookieBasedPersistentSearches and changeNumberBasedPersistentSearches fields.
Added SearchPhase enum.
Added CookieEntrySender, ChangeNumberEntrySender and SendEntryData static inner classes + made several methods static to call them from these classes.
In initialSearchFromCookie(), initialSearchFromChangeNumber(), notifyEntryAdded() and registerPersistentSearch(), set or retrieved attachments + used entrySender.
Extracted methods sendCookieEntriesFromCursor(), sendChangeNumberEntriesFromCursors().
Added initializeAttachements().
Split notifyEntryAdded() in two: notifyCookieEntryAdded() and notifyChangeNumberEntryAdded().

    …should not return the base changelog entry

I did the following changes:

- Persistent searches on cn=changelog with changesOnly=true no longer return the base changelog entry
- Fixed a functional bug with setting hasSubordinates on the base changelog entry:
-- hasSubordinates must be computed regardless of the search parameters, result can also be cached in memory once and for all
- As a consequence, it means we can immediately return the base changelog entry for initial searches without even looking for any subordinate changelog entries.
- Fixed a race condition when registering persistent searches: first set the cookie in the attachments then register the persistent searches
- implementing numSubordinates() was not required and it might be buggy, so returned -1 instead.


ChangelogBackend.java:
In notifyEntryAdded() (a.k.a. persistent search phase), never return the base changelog entry.
Removed EntrySender and moved all its methods back into ChangelogBackend + stored the MultiDomainServerState cookie as an attachment of the SearchOperation.
Renamed search*() to internalSearch*().
In hasSubordinates(), reimplemented it in a more efficient way + added baseChangelogHasSubordinates() and baseEntryHasSubordinates field to memoize its result.
In numSubordinates(), is not required, so just returned -1 + removed NumSubordinatesSearchOperation.
In registerPersistentSearch(), register the persistent searches after setting the cookie attachment on the search operation
Completed javadocs.

In registerPersistentSearch(), forced changesOnly=true persistent searches to never return the changelog base entry.
Renamed Entry.hasReturnedBaseEntry field to mustReturnBaseEntry to fit the fact the changelog base entry might never be returned + inverted all the boolean expressions related to this field.

CR-4439

Implementation of an additional validation of provided cookie when searching changelog
in cookie mode. 

Check for each state of the provided cookie that the csn is not older than the oldest CSN
available in each domain. If this is not the case, then an error 
ERR_RESYNC_REQUIRED_TOO_OLD_DOMAIN_IN_PROVIDED_COOKIE is returned. 

This check was done previously in the ECLServerHandler class but was not ported when
writing ChangelogBackend.  It also means I'm re-adding some methods deleted by the 
previous big clean done by Jean-Noel. 

Changes:
* ReplicationServer.java : 
  - add the check to validateServerState() method
  - refactor validateServerState() method for better readability
* ReplicationServerDomain.java : 
  - re-add getOldestState() method
* ReplicationDomainDB. java : 
  - re-add getDomainOldestCSNs(DN) method
* FileChangelogDB.java, JEChangelogDB.java : 
  - re-add implementation of getDomainOldestCSNs(DN) method

    Moved persistent searches from workflow elements to the backends.
Made persistent searches work for the ChangelogBackend.
Ensured the base changelog entry is always returned before any changelog entry, even with persistent searches. For this, used SearchOperation attachments to pass information from the "initial search" phase to the "persistent search" phase.
Added ChangelogBackend.notifyEntryAdded() and called it directly from the (JE|File)ChangelogDB and the ChangeNumberIndexer.

FIXME: prevent concurrent execution of initial vs. persistent search phases to avoid sending duplicates.
How do other backends deal with such issue? Apparently they don not deal with it.
TODO: verify changelog read privilege for persistent searches




Backend.java
Added persistentSearches field + registerPersistentSearch() and getPersistentSearches().

ChangelogBackend.java:
Replaced baseChangelogDN with CHANGELOG_BASE_DN and used it throughout + simplified ctor.
Added notifyEntryAdded(), getPersistentSearches(), isPersistentSearch(), isCookieBased(), getNewestCookie(), getChangelogDB(), getInstance(), NumSubordinatesSearchOperation.setAttachment(), TODO JNR
Overrode Backend.registerPersistentSearch().
Extracted method getExcludedDomains().
Renamed SearchParams.multiDomainServerState to cookie.
Removed unused SearchParams.operationId.
Added inner class EntrySender and moved methods to it: matchBaseAndScopeAndFilter(), sendBaseChangelogEntry(), buildBaseChangelogEntry(),
In searchFromCookie(), searchFromChangeNumber() and sendEntryForUpdateMessage(), simplified the code by using EntrySender.
Implemented finalizeBackend().

*Backend.java:
Called super.finalizeBackend()

ChangelogBackendTestCase.java:
Enabled as many tests as possible.



PersistentSearch.java
Added changesOnly field + isChangesOnly() + modified ctor to set it.

ReplicationServer.java:
Replaced old code enabling External Changelog (via workflow element) with new code (with ChangelogBackend).



FileChangelogDB.java, ChangeNumberIndexer.java, JEChangelogDB.java:
Called new ChangelogBackend.notifyEntryAdded().

ChangeNumberIndexerTest.java
Consequence of the change to ChangeNumberIndexer.

Consequence of moving persistent searches from workflow elements to the backends.
In performAdditionalPasswordChangedProcessing(), simplified code because we are adding to a Set.
Code cleanup.

LocalBackendSearchOperation.java:
Consequence of moving persistent searches from workflow elements to the backends.

    Preparation work: ChangeNotificationListener interface only cover a subset of its DirectoryServerPlugin superclass capabilities, so it is redundant.
So I removed ChangeNotificationListener to ease moving persistent searches to the backend.
The two ChangeNotificationListener implementations are now subclasses of InternalDirectoryServerPlugin.
Updated all code after removing ChangeNotificationListener.



ChangeNotificationListener.java: REMOVED



AuthenticatedUsers.java:
Now extends InternalDirectoryServerPlugin instead of implementing ChangeNotificationListener.
Extracted method getNewAuthNDN() + toDN().

CryptoManagerSync.java:
Now extends InternalDirectoryServerPlugin instead of implementing ChangeNotificationListener.
Extracted method getNewAuthNDN() + toDN().



DirectoryServer.java:
Removed references to removed type ChangeNotificationListener.
Be careful with when AuthenticatedUsers is initialized.

DirectoryConfig.java, LocalBackend*Operation.java:
Removed references to removed type ChangeNotificationListener.



CollectionUtils.java: ADDED

TestChangeNotificationListener.java:
Now extends InternalDirectoryServerPlugin instead of implementing ChangeNotificationListener.

AddOperationTestCase.java:
Extracted methods newRawAttributes(), byteStrings(), addSuccess(), addDisconnect(), bind(), writeAddRequest() + used CollectionUtils.
Consequence of the changes to TestChangeNotificationListener.

DeleteOperationTestCase.java:
Consequence of the changes to TestChangeNotificationListener.

ModifyOperationTestCase.java:
Extracted methods newModifications(), newRawModifications() + used CollectionUtils.
Consequence of the changes to TestChangeNotificationListener.

    These methods are useless because setChangeNumber() is never set inside production code, so changeNumber is always equal to -1 for all the update operations. In addition it is very unlikely the ChangeNumberIndexer could have computed the changeNumber before a results are sent to a persistent search.


AddOperation*.java, DeleteOperation*.java, ModifyDNOperation*.java, ModifyOperation*.java:
Removed changeNumber fields + getters and setters.
Code cleanup.

PersistentSearch.java:
In process*() public methods, removed the long changeNumber attributes.
Removed baseDN, scope and filter fields, and retrieve them directly from the SearchOperation.
Extracted methods isInScope(), isInScopeForModify(), isAnyInScopeForModify(), matchesFilter(), anyMatchesFilter(), sendEntry(), createControls().
to factorize duplicated code.

    to support cn=changelog
CR-4083

Implementation of core features of the changelog backend:
* Initialization and finalization of the backend
* Search of the changelog, in cookie mode (with a cookie control) and
  draft compat mode (by change number)

Note that :
* The support for persistent searches is not implemented yet.
* The changelog backend is currently not branched into code, i.e
 the directory server still uses the ECL workflow for "cn=changelog",
 because it is not possible to enable both changelog backend and ECL
 workflow at the same time (waiting for psearches implementation
before branching the new code)

Code changes:
* ChangelogBackend.java: 
   - implementation of search(), hasSubordinates(),  numSubordinates(),
     and getEntryCount() methods 

* ReplicationServer.java:
   - new dependency on ChangelogBackend and ECLEnabledDomainPredicate
   - new constructor with ECLEnabledDomainPredicate argument
   - new methods enableExternalChangeLog() and shutdownExternalChangelog()
     as future replacement of enabledECL() and shutdownECL()
   - new method getDomainDNs(Set<DN>) for retrieval of domain DNs but an 
     excluded set of dns
   - new method validateServerState(MultiDomainServerState, Set<DN>) for 
     checking coherency of given state with the replication server

* ReplicationDomainDB.java: 
   - new method getCursorFrom(MultiDomainServerState, PositionStrategy, Set<DN>)
     that exclude a given set of domain DNs from the cursor obtained

* FileChangelogDB.java, JEChangelogDB.java:
   - implementation of new method 
     getCursorFrom(MultiDomainServerState, PositionStrategy, Set<DN>)

* ECLEnabledDomainPredicate.java, ECLMultiDomainDBCursor.java:
  - update visibility to public in order to use these classes in ChangelogBackend

* ChangelogBackedTestCase.java:
   - test of ChangelogBackend class, built from ExternalChangeLogTest.java,
     with lots of renaming, refactoring, cleaning compared to original class
   - majority of tests are disabled until the changelog backend is branched into
     code (as these tests require a running server)

* MonitorTest.java:
  - update creation of  ReplicationServer class to use a custom 
    ECLEnabledDomainPredicate
  
 * replication.properties:
   - add messages for changelog backend
