- Fix in CegoTableManager::deleteDataTable, pBlock has to be checked
for null value, otherwise crash recovery might crash. ( bug came
with 2.39.0 to check for pBlock->getTriggerValueList )
- Some clob related fixes in CegoQueryHelper::decodeNativeFVL /
decodeFVL relevant for recovery handling
- Fix in CegoRecoveryManager::recoverCurrentTransactionLog for the
INSERT case. For the blob/clob handling, the lobREf values have not
been set up correctly. This might lead to problems for table recovery
with more than one lob row ( e.g. table t1 ( a blob , b clob )
Submitted by: Bjoern Lemke <lemke@lemke-it.com>
- Bug fix in CegoAction::reallocateStringBuf, in the memcpy call,
just the previous stringBufLen has to be copied ( _stringBufLen -
MAXSTRINGLEN ). This bug might lead to seg fault in case of large
parser input ( e.g. clob strings )
- In CegoQuery for insert and insert-by-select case, allocated blob
and clob data ( by CegoQueryHelper::prepareFieldValue ) is cleaned
now if any exception occurs
Submitted by: Bjoern Lemke <lemke@lemke-it.com>
- Small bug fix in CegoDistManager, which came up with version
2.39.0. In method deleteLocalDataTable, the variable delCount was
declared two times, which lead to a result of 0 tuples deleted in
any case
Submitted by: Bjoern Lemke <lemke@lemke-it.com>
- Small improvement in CegoDbThreadPool. For a better db thread
load value calculation, the request queue is no longer locked while
waiting for incoming requests. Instead the QUEUEDELAY parameter has been
increased to a default value of 200 msec to reduce db thread cpu
load while idle. Now the db thread has a good chance to report
idle time to the db thread pool.

databases/cegobridge: update 1.3.0 -> 1.4.0
cego:
- Fix in CegoTableManager::updateTuple, while setting up expression
list, field list array must be setup BEFORE block ist set, since
field list is needed by block setup ( in case of subqueries for
prepare )
cegobridge:
- Adaptions for cego-2.39
Submitted by: Bjoern Lemke <lemke@lemke-it.com>
- Introduced table locking statements to set an explicit lock on a
table ( e.g. for update synchronisation ). This feature replaces
the "set update sync on/off" command
- Trigger implementation basically completed
- Fix in CegoQueryHelper::encodeFVL, for blob/clob values lists,
the corresponding index variables ( blobidx/clobidx ) have not been
increaed while encoding lob data. This might lead to invalid results
and seg faults in case of multiple lobs values in one insert/update
operation.
Submitted by: Bjoern Lemke <lemke@lemke-it.com>
- For heavy update operations on tables with btrees using embedding
transactions, duplicate btree errors may occur. This is caused
by not checking corresponding tuple states. To solve this problem,
the following fixes have been done :
o Fix in CegoTableManager::checkBTreeIntegrity : The tuple state for
found entries has to be checked if state = COMMITTED
o Fix in CegoBTreeNode:checkForAffected ( was checkForDeleted before ) :
The tuple state has already checked for state
INSERTED if tid != dataTid
Submitted by: Bjoern Lemke <lemke@lemke-it.com>
- Fix in dbcheck/check065.sql for union sql in view.There must be
set up aliases for attributes in selection now
Submitted by: Bjoern Lemke <lemke@lemke-it.com>
- Fix in CegoTableManager::createForeignKey, for empty tables,
referenced attributes names have not been checked. This might lead
to invalid key objects.
- Fix in CegoSelect::prepare, expression alias in select list are
checked now for union selects. Alias definition in select expression
list should be identical for all select statements in union
Submitted by: Bjoern Lemke <lemke@lemke-it.com>
- Increased NETMNG_QUEUE_DELAY to 1000000 ( 1 ms ) to minimize CPU load
- Introduced QUEUEDELAY ( in usec ) config parameter to adjust queue
delay in database xml file. This allows to throttle down database
response time for incoming connection requests and minimize CPU
load
- Added dbcheck/check072.sql. This implements the calculation of
fibonacci numbers using stored procedures as a demonstration for
massive recursive procedure calls
- Optimization for procedure load in CegoFunction::evalFieldValue
( case USERDEFINED ), procedure is just loaded as a dedicated
instance ( via loadProcedure method ), if pMasterBlock is set. This
avoids ( expensive ) dedicated load, if the procedure is still not
in use by the corresponding thread. So just for recursive procedure
calls, the dedicated load happens.
Submitted by: Bjoern Lemke <lemke@lemke-it.com>
databases/cego: update 2.38.12 -> 2.38.14
lfcbase:
- Stability patch for strptime implementation ( MinGW only )
cego:
- Fixed memory lead in CegoDistManager destructor ( _pPA was not deleted )
- Further optimization done in CegoBTreeCursor, introduced methods
traceLow and inRange to treat btree comparison in a more efficient way
- Fix in CegoAttrCond::getIndexCond, like and no like comparisons
must be filtered out for new btree cursor tracing logic
Submitted by: Bjoern Lemke <lemke@lemke-it.com>
- Small optimization in CegoAttrCond::checkIndex, removed primary
flag, since this is done now by attribute ordering. This leads
to full index trace match instead of trace with index support and
so, additional unnecessary predicate evaluation is avoided.
- More rework for btree evaluation in CegoBTreeCursor
- Optimization in CegoBTreeCursor::getNext. Instead of calling
getNext in a recursive way, this is now done in a iterative way.
This might avoid heavy stacking in case of special query constraints
( e..g multi dimensional btrees and range conditions like a > 400
and b betweeen 'AAA' and 'DDD' )
Submitted by: Bjoern Lemke <lemke@lemke-it.com>
databases/cego: update 2.38.9 -> 2.38.10
lfcbase:
- Fixes in TreeT class, changed methods First, Next, isEmpty and
compare operators to const
cego:
- Fix in CegoDistManager, we have to use a dedicated parser for
loadView and loadProc methods. Otherwise compilation may fail in
case of nested objects ( e.g. a view which references another view
object)
- Fix in CegoBTreeCursor, CegoAttrCond and CegoAttrComp, for
conflicting cursor conditions ( e.g. a = 4 and a < 1 ), the cursor
evaluation failed, since just the primary condition was treated.
- For CegoBTreeCursor, the method fullMatch has been introduced,
to make an final evalution in case of multi conditions.
- Also introduced: a ordering for CegoAttrComp set in
CegoAttrCond to treat more constraint conditions at the beginning
( EQUAL before LESS_THAN before NOT_EQUAL and so on )
- Changed CegoAttrCond compSet from SetT to TreeT.
This is required, since we need the ordering in the set.
Submitted by: Bjoern Lemke <lemke@lemke-it.com>
- Introduction of new functions ascii ( get ascii character for
numeric value ) , ldiv and lmod ( div and mod operation for long
values )
- Modification in CegoFunction::evalFieldValue. To allow recursive
calls of user defined functions and procedures, dedicated procedure
instances are created for each call. This is done by parsing the
procedure text via CegoAction
Submitted by: Bjoern Lemke <lemke@lemke-it.com>
databases/cego: update 2.38.6 -> 2.38.7
lfcbase:
- Improvements made for dedicated strptime implementation. The
function did not return null in case of unparsable date values.
This code is just used for MinGW compiles since there is no
implementation in the Standard C library available.
cego:
- Fix in CegoXPorter::readTableObject, the defintion for MAXROW BUF
still was defined locally and rowLen was noch checked.
- Optimization in CegoFieldValue::decode, memory was allocated via
malloc, rather _staticBuf should be used for performance reasons.
_isLocalCopy was not set to true
Submitted by: Bjoern Lemke <lemke@lemke-it.com>
databases/cego: update 2.38.5 -> 2.38.6
lfcbase:
- More detailed exception messages for BigDecimal and BigInteger
cego:
- Fix in CegoFunction::getId and CegoSelect::getQueryId : with
enabled query cache, the following select is cached
select nextcount(mycount);
- Since nextcount is a modifying operation, this is not a good idea.
To avoid caching, CegoFunction now throws an Exception if
nextcount / setcount function calls are detected during getQueryId.
For these cases, the query id ignored for caching
Submitted by: Bjoern Lemke <lemke@lemke-it.com>
- Fix in CegoBTreeValue::valueFromSchema, introduced method
getReservedLength to return fixed value length for type fixed and
decimal. Since for decimal and fixed type just the dimension is
stored in CegoField::getLength, we must define a reserved area
for those types. This is done now with constant definition
RESERVED_BTREE_FLOATLEN in CegoDefs.h
- Improved ordersize calculation in CegoOrderSpace:insertTuple. Now
the following formula is used :
int s = sizeof(fv);
if ( fv.getLength() > STATICFIELDBUF )
s += fv.getLength();
orderEntryLen += s;
The catches the base memory usage for the instance but also the
dynamic allocated part
Submitted by: Bjoern Lemke <lemke@lemke-it.com>
- Fix in CegoXMLSpace::setTSSortAreaSize, changed type from int to
unsigned long long, otherwise overflow may occur for large sort
area size configurations
- Performance optimization done in CegoOrderSpace. Instead of storing
the CegoField list for the result tuple in CegoOrderNode, just the
values are stored there. The order cursor now gets the schema with
the constructor and build the CegoField List in the getFirst /
getNext methods. This seems a huge amount of heap space, which is
dynamically allocated during the sorting procedure ( sortareasize
parameter ).
Especially for large ordering result sets this saves significantly
memory and improves performance.
Submitted by: Bjoern Lemke <lemke@lemke-it.com>
- Fix in CegoPredDesc::decode, loop variable i for IN/NOTIN case
was not initialized
- Fix in CegoAction::execCheckCreate, check contraints are checked
for contained subselects. subselects are ( still ) not supported
since the CegoCheckOject::decode method can not provide a valid
tablemanager instance ( it is called from CegoObjectManager )
Submitted by: Bjoern Lemke <lemke@lemke-it.com>
databases/cegobridge: update 1.2.1 -> 1.3.0
cego:
- Fix in CegoSelect::clone, pUnionSelect was not cloned, which might
lead to seg faults
- Introduced predicate clause for select .. in ( expr, expr, ... ),
e.g. select * from t1 where a in ( 1, 2, 3 ); This was still not
implemented but is part of standard SQL.
cegobridge:
- Adaptions made for modified cego-2.38.0 API with extended
CegoDatabaseFormatter::formatPred method ( exprList was added for
new introduced select in ( expr list ) predicate )
Submitted by: Bjoern Lemke <lemke@lemke-it.com>
- Fix in CegoClient, the new comment logic by using Tokenizer does
not work ( '-' characters are detected as comment tokens ). Code
replaced by using posStr chain function
- Adaption in CegoMain to also parse comment lines in a more
sophisticated way ( same as in CegoMain ), just relevant for server
batch mode
- Optimization in CegoDistCuror::joinSetup, the join predicate is
now analysed in a way, that a condition list is created ( via makeCNF
and createCondition methods in CegoQueryHelper ). The condition
list then is analysed to achieve a better cursor condition which
results in improved index usage
Submitted by: Bjoern Lemke <lemke@lemke-it.com>
databases/cego: update 2.36.4 -> 2.37.0
databases/p5-DBD-cego: update 1.3.0 -> 1.4.0
databases/cegobridge: update 1.1.6 -> 1.2.0
lfcbase:
- Layout improvements in Pager class
- Changed constructor for Net and NetHandler class to setup maxSendLen.
Since this changes the API, minor release level has been increased
cego:
- Improvements for cgblow simulation mode added
- Improvements for cgclt, added pipe mode to read input from stdin
Now comments are allowed also after delimiter token, e.g.
create table t1(a int); -- a sample table
- Support for lfcbase-1.11.x with new Net API.
The parameter maxSendLen ist still a constant in CegoDefs.h
Improvements added for CegoXMLSpace::setPerm, for existing permissions,
just tableset, filter or right can be set up now,
e.g set permission p1 with right=WRITE for role1 just sets the right
value for permission p1 to value WRITE, all other values are unchanged
- Added show parameter admin command to show all tableset independent
database parameters
p5-DBD-cego:
- support changed API with lfcbase-1.11.0
cegobridge:
- support changed API with lfcbase-1.11.0
Submitted by: Bjoern Lemke <lemke@lemke-it.com>
databases/cego: update 2.36.3 -> 2.36.4
databases/cegobridge: update 1.1.5 -> 1.1.6
cego:
- Fix in CegoSelect::nextTuple, before adding an entry to the query
cache, it has to be checked, if any tables from foreign tableset
are referenced in the query. If so, no cache entry is made, since
table changes for foreign tables are not detected.
- Improved error messages for invalid database objects
- Decreased shutdown delay time by reducing net delays for all
thread pools and optimized mediator thread wait procedure
- Completely removed the nologging option for import actions.
Logging is disabled in any case now.
- Optimization added for log handling. During ( xml ) import,
logging is completely deactivated, after import is completed,
log is started again and a checkpoint is written.
Since import can be repeated in case of a system during import,
nothing gets lost. Deactivating logging increases import speed and
avoids side effects
cegobridge:
- Speed up imports by changing the way the parser reads the input
Submitted by: Bjoern Lemke <lemke@lemke-it.com>
- Changed recovery strategy for existing btree / avl index objects.
Before creating an index object, it is checked if exists. If exists,
it is dropped and recreated. This seems to be a more stable strategy,
since it may occur, that index objects still exist for several
reasons.
Submitted by: Bjoern Lemke <lemke@lemke-it.com>
- Fix in CegoFactor::setFieldListArray, the _flaCached variable has
to be set to false, if _pFLA is set to a different value. Otherwise,
we might refer to invalid memory, which results in core dump
Submitted by: Bjoern Lemke <lemke@lemke-it.com>
- Added signal handler to CegoAdmAction. Now, ( long ) running
tableset export and import requests can be aborted in a controlled
way via Ctrl-C command.
- Fix in CegoXPorter, export file will be removed, if any exception
occurs. So it is ensured, that the written export file is consistent
and complete
- fixes in CegoXPorter for CLOB handling ( was not checked for plain exports )
Submitted by: Bjoern Lemke <lemke@lemke-it.com>
- Completed pointer cleanup in CegoQueryHelper::evalPredicate, added
check061 to check pointer cleanup
- Fix in CegoTableManager::createBTree, pC object cursor has to be
set to 0, otherwise in case of abortion a seg fault occurs
- Changed default value for btree cache enabling to false
- Improvement in CegoBufferPool::calcSegment for segid calculation.
It has been recognized, that with the current calculation
( pageid % numsegment ) not all slots can be reached for
special buffer pool configurations.
The formula has been changed ( to ( pageid / numpages ) % numsegment )
- Adding missing export / import messages to CegoXPorter
- Changed btree cache enabling syntax. Instead of a dedicated switch
command ( set btree cache on / off ), the cache option now is
directly given with the create btree command ( e.g. create btree
b1 on t1(a) cached )
Submitted by: Bjoern Lemke <lemke@lemke-it.com>
- Fix in CegoBufferpool::writeCheckpoint, in case of an locking
exception ( lockBufferPool ), the pool must be released in any case.
For this the CegoLockManager::lockBufferPool and
CegoLockManager::unlockBufferPool have been modified in a way,
that lockBufferPool saves the current sema index ( _poolRangeLock )
which is later used for the unlocking call.
- Timeout parameter for bufferpool lock reduced to 60 seconds.
- Optimization in CegoBufferPool:bufferfix for minHashId calculation
in step 2, there was an unneeded locking operation for the
minhashId, which was already locked by the main loop
- Small format fix in CegoProcCreateStmt ( missing indent )
- Add header row out put for client raw mode ( attribute names )
- Fix in CegoQueryHelper::evalPredicate, for all predicate types,
the field array value has to be reset to 0, otherwise seg fault my
occur since invalid references might be used
Submitted by: Bjoern Lemke <lemke@lemke-it.com>
- Fix in CegoQueryHelper::aggregateTuple, in case of min-Aggregation,
wrong results may occur, if null values have to be treated. Since
null value handling is now treated inside CegoFieldValue, some code
here was obsolete.
- Fix in CegoPredDesc for INSUB and NOTINSUB constructor + clone
method. There was a confusing with the isNegated flag which has
been corrected ( also in using class CegoAction ) The wrong negation
might lead to wrong query result for views using subselect with in
or not in subselects
- Bug fix in CegoDistCursor::getTuple, for the LEFTOUTER case and
moreRight conditions, the right table cursor was called double time
( native and with nextRight ). The native call has to be removed
since this may lead to strange effects actually just observed for
mingw compiles
Submitted by: Bjoern Lemke <lemke@lemke-it.com>
- Added tuple information command tupleinfo to indicate
tuple state information for a given table
( COMMITTED, INSERTED, DELETED, OBSOLETE )
- Fix in CegoTransactionManager::commitTransaction and
CegoTransactionManager::rollbackTransaction, in case of a crash recovery
the taList does not contain any transaction entries, but the rollback
segments have to be checked in any case for entries to process. Otherwise,
the transaction will not be completed
Submitted by: Bjoern Lemke <lemke@lemke-it.com>
databases/cego: update 2.35.2 -> 2.35.3
lfcxml:
- Small improvement in XMLSuite::nextChar to check for non-ASCII characters
cego:
- Fix in CegoTableManager::finishOpenTransaction, the transaction id for
the corresponding tableset must be set to zero, otherwise in case of crash
recovery procedures a transaction id might be active and the open
transactions are not completed correctly
Submitted by: Bjoern Lemke <lemke@lemke-it.com>
- Fix for a bad patch
In CegoSelect::clone also the pCache variable has to be copied
( was previously done by calling setTabSetId )
Submitted by: Bjoern Lemke <lemke@lemke-it.com>
- Fix in CegoSelect::setProcBlock, pBlock was not setup for _pPred
This might result in wrong query results within stored procedures
with select statements which refer to procedure variables
- Changed index recovery handling in a way, that index and btree
objects are rebuild immediately instead of invalidating them. This
leads to a much better recovery performance in case of expensive
queries where index use is needed for fast evaluation
Submitted by: Bjoern Lemke <lemke@lemke-it.com>
- Fix in CegoDistManager::checkKey ( used for verify tableset admin
commend ). Check for foreign key has been redesigned
- Fix in CegoBTreeCursor::getFirst, _pAttrCond has to be checked
for 0, otherwise a core dump may occur ( detected with verify
tableset admin command )
- In CegoViewObject::toChain() the view object reference string has
to return complete information including the tableset. Otherwise,
references to foreign tableset objects with the view will not work
correctly.
- Fix in CegoDistCursor to support multiple view references in a
query ( e.g. select a from v1 where exists select * from v1 ... )
In the past, this might lead to infinite loops, since just the view
select reference was used. Now the reference is cloned.
The usage of clones results in several fixes for the CegoSelect::clone
and underlying clone methods
- The previous problem regarding query cache is a result of the new
introduced select cloning. The extended query id string should solve
the problem
- Fix in CegoSelect::getId, the values of the parent join buffer
have also be added to the query id string, otherwise, nested queries
which references attributes to parent join buffer can not be
distinguished
- Introduced simple selects, e.g. select 1, select sysdate, etc for
select queries without any object access
This might be useful for example for database connection validation queries
Submitted by: Bjoern Lemke <lemke@lemke-it.com>
databases/cego: update 2.33.22 -> 2.34.0
lfcbase:
- Adoptions made in CommandExecuter and Outstream for MINGW builds
- Added Datetime advanced constructor for more efficient datetime construction
cego:
- Small fix in CegoAttrCond::operator = , compare Find result
with 0 instead of false. A compile error occured for MINGW compiles
- Use of new introduced lfcbase datetime constructor to create
datetime values with numeric input ( year, month, day, hour, minute
and second ) for more efficient value handling
- Fix in CegoTypeConverter::getTypeLen for LONG_TYPE values, it
should be size of(long long) instead of sizeof(long). This impacts
MINGW compiles, since sizeof(long) ist just 4 bytes
- Changed CegoTypeConverter methods to static
- Introduced new date function newdate with optional numeric input.
If used with year and month input, this can double the speed for
date construction ( no string parsing required )
Submitted by: Bjoern Lemke <lemke@lemke-it.com>
- More fixes in CegoTableManager::keyReferenceExists and
CegoTableManager::createForeignKey, there still were missing some
adpotions for TableCursor::setup return code and other case handling
Submitted by: Bjoern Lemke <lemke@lemke-it.com>
- Added further constraint check in CegoTableManager::dropObjectSynced.
Primary objects just allowed to be removed, if no foreign key
reference exists
- More fixes on foreign key contraint handling in
CegoTableManager::checkKeyIntegrity and CegoTableManager::insertDataTable
methods
- Fix in CegoTableManager::checkKeyIntegrity. The implementation
of the mehod has been completly reworked, since not all violation
cases have been treated.
Submitted by: Bjoern Lemke <lemke@lemke-it.com>
Fix in CegoDistCursor to support advanced left and right outer
join queries of the form
SELECT tx.a AS xa, ty.a AS ya FROM t1 tx
LEFT OUTER JOIN t2 ty ON tx.a = ty.a + 1;
For this, the evaluation of the predicate has to be done in a
different way to get complete row set
Submitted by: Bjoern Lemke <lemke@lemke-it.com>
- Fix in CegoOrderSpace::insertTuple, for the localTuple variable,
also a dedicated copy has to be allocated, otherwise it may happen
that invalid tuple references ( caused be page relocation ) lead
to invalid order results
- Added performance optimization to CegoTableManager::updateTuple.
The already evaluated index, key and checklist are also provided
to checkIntegrity method now ( instead of retrieving the lists again).
The improves performance for updates with many tuples significantly
Submitted by: Bjoern Lemke <lemke@lemke-it.com>
- Method cleanup in CegoSelect.cc, also some irrelevant case is
treated for grouping clauses in combination with distinct operator
- Added tablemanager parameter to CegoProcWhileStmt to catch query
abort. In case of infinite while loops, this enables the db admin
to abort procedure execution
- Optimization for CegoFunction::SETCOUNT procedure implementation
added. Now this is an atomic operation, instead of calling
getCounterValue.
- For this, also the CegoXMLSpace::setCounterValue method has been
changed to return the current counter value return the current
counter value
Submitted by: Bjoern Lemke <lemke@lemke-it.com>
- Completion for admin help backup section, some commands were still missing
Improvements for procedure indent formatting. All sugar, nothing functional
- Fix in CegoAction::execute, missing break added after calling execListView
- Fix in CegoQueryHelper::evalPredicate. In case of subselects, the
parent join buf also has to reset after performing the subselect,
otherwise invalid pointer references are still active for the next
caller
- Seg faults have been experienced for delete with double nested
subselect conditions ( see check055 )
Submitted by: Bjoern Lemke <lemke@lemke-it.com>
- Design modification in CegoAction for semantic action ( execXXX methods )
An analysed statement is now just executed after complete succesful
parsing of the given input. This avoid protocol effects for queries
like "select * from t1;;" where the query is executed but the
second semicolon is detected as an parse error which also is sent
to the client.
For this the new method CegoAction::execute has introduced which
is ( explicitly ) called after successful CegoAction::parse
- Fix for distinct handling in CegoAggreation
Fix for alias handling regarding view creates. Alias definitions
are mandatory now for aggregated attribute definitions, e.g.
create view v1 as select count(*) from t1;
=> returns now
ERROR: Missing alias reference for view create
and must be written as
create view v1 as select count(*) as c from t1;
Submitted by: Bjoern Lemke <lemke@lemke-it.com>
- Fix in CegoAttrComp::reset, case VALUE2VALUE still was not treated,
which lead to wrong index handling for between clauses with native values
Submitted by: Bjoern Lemke <lemke@lemke-it.com>
- Fix in CegoObjectManager::createBTreeObject to avoid some duplicate btree
entries
- Added space character in CegoSelect::toChain after distinct keyword
to avoid certain errors
- Fix in CegoAttrComp::operator== The values should NOT be compared,
since they are set up by the calling CegoAttrCond::update method
Otherwise, the error "Cannot set up diff for attribute condition"
occurs.
basecheck54 added to test for the this problem
- Fix in CegoQueryHelper::evalAttrCond, comparison modulation was
missing for one case whihc leads to wrong query results for comparisons
like 3 < a ( constant left )
- Optimization added for between clause, indexes were just used for
constant values in between clause ( eg. a between 10 and 20 )
This has been expanded, that also indexes are used, if attribute
references are contained ( eg. a between t2.x and t3.y )
Submitted by: Bjoern Lemke <lemke@lemke-it.com>
- in CegoTableManager::getClobData added termination character to
ensure clob values are terminated with 0 character
- Small fixes for fixed value handling
- Small fixes for quote escape handling in cgclt batch mode
- In CegoAction::selectionList1 added alias check for non unique
alias definitions
- Stored Procedure formatting improvements regarding indent handling
Submitted by: Bjoern Lemke <lemke@lemke-it.com>
- Fix in CegoSelect::buildJoinConditions, the _attrPred array has
to be set up. Otherwise it may occur, that the predicate is not
evaluated, if it could not been evaluated by the table curser
condition.
- Furthermore, a setup method has been introduced for CegoAttrCond
to evalute joinBuf and parentJoinBuf ( if both references occur in
a condition this is needed )
- Optimization in CegoCheckpoint::checkpointReached, if interval
was reduced, we set up the new interval
- Fix in CegoTableManager::removeAllComp, first we have to remove
from the list, the we can free the memory. On Linux system with
g++, the previous sequence might lead to memory faults
- Fix in CegoRecoveryManager::recoverTableSet, after regDataFiles,
als registerObjects method must be called, otherwise recovery could
fail in case of table view recoveries
- Optimization in CegoDistManager::stopDistTableSet, the new
introduced method CegoDatabaseManager::removeAllObjects is called,
the ensure object cache cleaning
- Added prompt command line option to cgadm to set up specific prompt value
- Adding formating improvements to CegoAdminHandler for show logmng
and show backupmng commands
