devel/lfcbase: update 1.11.3 -> 1.11.4
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.

databases/cego: update 2.38.7 -> 2.38.9
- 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

devel/lfcbase: update 1.11.2 -> 1.11.3
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

devel/lfcbase: update 1.11.1 -> 1.11.2
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

databases/cego: update 2.38.3 -> 2.38.5
- 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

databases/cego: update 2.38.1 -> 2.38.3
- 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.

databases/cego: update 2.38.0 -> 2.38.1
- 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 )

databases/cego: update 2.37.3 -> 2.38.0
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 )

databases/cego: update 2.37.1 -> 2.37.3
- 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

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:

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

databases/cego: update 2.36.2 -> 2.36.3
- 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.

databases/cego: update 2.36.0 -> 2.36.1
- 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 )

databases/cego: 2.35.10 -> 2.36.0
- 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 )

databases/cego: update 2.35.8 -> 2.35.10
- 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

databases/cego: update 2.35.4 -> 2.35.8
- 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

databases/cego: update 2.35.3 -> 2.35.4
- 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

databases/cego: update 2.35.0 -> 2.35.1
- 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

databases/cego: update 2.34.0 -> 2.35.0
- 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

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 )

- 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

databases/cego: 2.33.12 -> 2.33.14
- 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;

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 )

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

databases/cego: update 2.33.4 -> 2.33.5
- Fix in CegoSelect and friends for query cleanup. The cleanUp
method did not cleanup all field value references which might lead
to invalid memory access in case of repeated view calls ( Variable
pParentJoinBuf ).
Corresponding cleanUp method have been introduced or CegoExpr,
CegoTerm, CegoFactor and friends.

curses option in Pager class, replaced CGNOCURSES with LFCNOCURSES
cego:
- Fix in CegoRecoveryManager::recoverTableSet, before calling
transactionRecovery, we have to set flag setIgnoreInvalid to true.
During transaction recovery phase, we must ignore invalid btrees/index
objects since these objects could be invalidated but Log data
integrity and consistency is ensured
- Added implizit tableset btree and index correction to recovery procedure
( CegoRecoveryManager::recoverTableSet )
- Small syntax for cgadm from "backup TS" to "backup tableset TS"
( conform to other tableset commands )
- Fix in CegoTableManager::deleteDataTableEntryAtomic /
updateDataTableSynced / beginTransaction / commitTransaction /
rollbackTransaction to avoid log entries for forced transactions
( introduction of doLog flag ).
- Fix in CegoTableManager:deleteDataTable to avoid object synchronisation
during recovery phase ( introduction of isSynced flag ), since
during recovery phase, still no objects are registered and there is
no need for synchronization
- Added further admin console messages for recovery procedure.
This enables the database admin to follow the recovery procedure on
admin console level

- Small grammar correction to treat distinct flag for select-star statement
- Fix in CegoBTreeCursor::compValue, null values have not been handled
correctly. For string values, string termination was not clean, which
also might lead to wrong cursor results
- Introduced archive manager, which can be triggered, to perform
an online backup. For now, online backups have to be triggered
externally.
The achive manager should make backup / restore handling more convenient
- Update to version 2.33.0 since the backup feature changes the product
specification.
- Integration of newly introduced lfcbase OutStream class to catch output
from backup manager. This allows to indicate a more detailed
output from backup manager on the admin console.

delete key is disabled
cego:
- Correstion for distinct clause. With the current grammar implemention,
queries with nested selects and using the distinct operator might
fail. Cego.def grammar and CegoAction implementation has been changed
in way, that distinct option is just allowed at the beginning ( e.g.
select distinct count(a) from t1 and NOT select count(distinct a) from t1 )
This should simplify usage, since by using the distinct clause,
distinct tuples are retrieved either for plain queries or for
aggregation
Confusing sample not allowed anymore : select count(distinct a),
count(distinct b) from t1 ... now select distinct count(a), count(b)
from t1 )
- Fix in CegoBTreeValue::valueFromSchema added.
In case of multidimension btree objects, the insert of new values
might fail, if string bases attributes occur at the beginning
- Fix in CegoDistManager::registerObjects, registration of btree
objects was still missing. This might lead to wrong results for
drop if exists btree statements
- Added check to CegoXMLSpace::addArchLog to verify, that directory
for new archive location really exists
- Added archive log management to curses based CegoAdmMon administration

- Fix in CegoDistManager::stopDistTableSet, removing of btree objects
from database object dictionary was still missing
- In CegoTableManager::dropTableSet now also counter objects are
dropped ( stored in the database xml file ).
- Added some sizing optimizations for CegoAdmMon forms
- Fix in CegoRecoveryManager::recoverCurrentTransactionLog, added
the force option to addCounter method, since counters already could
be synched to xml ( not completely transaction save )
- Online index build up tested and verified. First tests with heavy
insert operations ( using cgblow ) during index build went succesful.
- Improvements for CegoAdmMon role permission handling, added remove
permission option
- Preparation of CegoObjectCursor and CegoTableManager to support
online index rebuild with write access to the table.
For this, concurrent insert operations have to be performed with
append =true. The ObjectCursor locks the last page until the index
rebuild is finished ( method setLastPageSync )
In this way, the index can be build up in parallel, while further
tuples could be appended to the table. ( just supported for btree
index objects )

databases/cego: update 2.32.3 -> 2.32.4
- Fixes and improvements for table export added
In CegoXPorter::xmlExportable, the pOutStream pointer was deleted,
which lead to a core dump ( pointer is already deleted by Element )
Row counter handling and messages have been improved
- Change back to memove call in CegoBTreeNode:shiftEntries. Copying manually
and bytewise decreased performance about two times for building
up btree objects. This has been observed on native POSIX ( FreeBSD 11 )
but also on MSYS64 compiles
- Improvements for CegoBTreeCursor. With the new introduced methods
CegoBTreeNode::getMedPage and CegoBTreeNode::rightValue, the search
for the appropriate subnode can be made with logarithmic efforts
instead of linear search. To validate this improvement, the following
query has been setup for a random filled table t1
select * from t1 ta where exists ( select * from t1 tb where tb.b = ta.b );
Execution time with the improved btree cursor was two times faster than with
old implementation.
- More performance improvements made for btree creation
changed linear search efforts in CegoBTreeNode::getChildPage to logarithmic
search efforts ( introduced lb /rb variable )
- Change in CegoBTreeManager::allocPage. Since for cache based creation,
just a pageId must be allocated, the low level method
CegoFileHandler::allocatePage is used.This avoids an unnessary
bufferFix call for the new page
- Introduced appendFid variable for CegoFileHandler class. In case of
many managed datafiles, the last file with avaiable pages is used
for the allocatePage method.
- Performance comparison to MariaDB indicates now a better scaling
from 2 million rows and up ( by using cego btree cache )
- Improvement modifications for btree implementation increased build
up speed for just about 3 percent. It seems, the most time is used
by calling shiftEntries method, where memory is moved via memmove.
I observed, that 8k page size ( instead of 16k ) brought up some
performance improvement for btree creation of about 100% ( for
type string(60) with random values )
- More performance improvements in CegoBTreeManager and CegoBTreeNode,
overall impact still has to be analysed
- Fix in CegoTableManager added for alter table modify column,
columns with existing btree or key objects can not be modified
anymore
- Further improvement approach in CegoBTreeManager to increase btree
creation performance. BufferPage handles have been changed from
native variables to pointer handles. This should reduce page access
efforts in case of enabled btree cache

which leads to a hanging database client. Since class CegoQuey

cego:
- This version brings a complete redesign of low level page handling.
Instead of page references identified by fileId and pageid, a
database unique pageid is used now
This results in a complete reimplemtation of several low level
classes like CegoFileHandler, CegoBufferPool, Blob handling, etc.
Since pages are references by a single ( 64 bit ) id now, I expect
an increased performance behaviour over all database operations.
Most code modifications are done, code complies and basic
functionally works ( create tableset, create table, insert table )
- First performance analysis indicates a speedup of about 10% for
btree creation, so significant speedup for full table scans.
- All base checks passed, but there is still a page allocation leak
for table drops

Do not use post-stage. Use post-install instead.
The only reason to use post-stage is because the port needs to do

concurrent affected tuples
- Reactivation of rollback segment record locks in CegoLockHandler class.

an incomplete recovery procedure
- Improvements for tableset recovery, external log manage field is
checked in CegoAdminThread::medRecover before restore procedure is
started.
- Fix in CegoLogManager::logAction, if online redo log is full, the
current log entry has to be written anyway, otherwise a checkpoint
is written and subsequent logAction call in CegoTableManager::logIt
might lead to duplicate entries in case of a crash recovery
- Fixes for query and table cache added (addEntry method was still not clean)
- Added tableset runstate CHECKPOINT to be set during a tableset
checkpoint is performed.
Since this is a critical section in terms of data consistency,
no system crash should occur while writing a checkpoint.
If so, the tableset now is marked with status CHECKPOINT and cannot be
used anymore ( tableset recovery from backup required )
- Patch in CegoDistManager::startTableSet, before starting redo log
file recovery, the tableset state has to be set to RECOVERY
Otherwise, occupied redo logs are not archived by the log manager.
This problem might occur in case of a crash recovery with archive
mode set to ON
- Patch in CegoQueryCache and CegoTableCache ( for each method addEntry )
The usedSize calculation was not done correctly for replaces entries
- Added table and cache used size information to show tableset admin command
This indicates the amount of memory, which is already allocated
for cached data
- Added synrchonization for query and table cache handling.
The lack of synchronization might lead to core dumps, if a cache
entry is freed but also be used by a query
So before cache cleanup, it has to be checked,
if the corresponding cache entry is still in use
If so, it has to be wait, until the cache is clean. For both
caches ( query and table), the similar logic is used
- Added improvement for query cache handling
If a stored function, which are used in the cached query, was
modified, the cache entry will be invalidated
For this, the CegoSelect::getTableList method was changed to
CegoSelect::getObjectList and also the used functions are evaluated
and added to this list.
- Adapted sysmtexp and sysmtimp X-port utilities for current schema definition
- Cache cleanup in CegoQuery class is performed now AFTER the
modifying action.Otherwise, it may appear, that a cache entry is
made after cache cleanup but also before the modifying action.
This may lead to wrong results retrieved from obsolete query cache

databases/cego: 2.30.6 -> 2.30.7
- Fixed memory leak in CegoSelect::nextTuple.
Since the querycache is allocated by the CegoQueryCache instance, the
pCacheList variable has to be freed after calling the addEntry method.
Actually, the logic is not very smart, since the cache element is build up
two times...

databases/cego: 2.30.5 -> 2.30.6
The following query can cause a core dump
create table t1(a string(100));
insert into t1 values ( 'Hugo Habicht');
insert into t1 values ( 'Kim Kaiser');
select substr(a, 1, getpos(a, ' ')) from t1;
For return value length evaluation, the method CegoFieldValue::asInteger
is called on a null value which causes the dump. A fix has been
added, so the method returns a value of 0 in case of null values.

for both dedicated tableset entries are managed. Cache enabling,
cache size and num entries can be controlled now on tableset level.
- Fixes for date format handling. The format string whihc is specified
for the server is also used now for client formatting. This results
in some network protocol fixes for serial but also xml network

- Fix in CegoDistManager::dropDistObject, table and query cache
have been checked for cleanup, if a table is dropped
- Fix in CegoQuery.cc, added table and query cache cleanup for alter

- Fix in CegoClient to parse multi line statements correctly. Further
multi line merge token ( \ ) has been added to merge long string or
clob values. Now the following statements are possible:
insert into t1 values ( 1, 'this is\
a multi line \

lfcbase:
- Fix in Datetime.cc, added include config.h, otherwiese the local
implementation of strptime ist used. This should just be done, if
the system API does not provide this call ( e.g. MINGW ) .
- Memory leak fixed in File::readLine
cego:
- Started with clob datatype implementation
- Fix in CegoSelect constructor, _cacheEnabled var was not initialized
in the decoding constructor, which might lead to core dumps in case
of recovery of complex with enabled querycache Fix in CegoAdminThread
constructor, disableAuth method for TableManger called, otherwise
tableset recovery might fail with auth error
- Required network protocol expansions done for clob handling
(putclob, getclob, delclob)
- More work on clob handling. A fix was done for update operations
on clob values in CegoTableManager::updateTuple method. Before
updating the tuple, all clob references must be cloned, otherwise
in case of untouched clobs, references are invalid. This approach
is brute force, better would be, to stay on the untouched clob
references. But in terms of transaction and recovery handling,
this is not trivial
- Very long strings are handled now in CegoAction and CegoClient
to also parse large clob values
- Modification in cgclt for raw mode, Now just plain data is listed,
with the command line option --raw=X, a separator token can be setup
as a column separator

IMPORTANT: Upgrades of cego 2.27.x to 2.28.x databases has to be done by
export and import.
lfcbase:
- Adaptions made for build with msys2 / mingw64. Many windows
specific stuff could be eliminated, since mingw64 provides better
POSIX support ( e.g. pthreads, timer functions .. )
lfcxml:
- Fix in configure.ac to find lfcbase and for FreeBSD
cego:
- Fix in CegoSelect::CegoSelect, the pCacheList variable was not
initialized to 0 for all constructors. In case of system table
selects, the variable might be undefined which might lead to
segmetation faults.
- Changed synchronization level for btree creation. So the base
table can also be accessed while btree is created ( During creation
btree status is invalid )
This also allows to perform on online btree reorganization, since
a new btree can be build up in parallel
- Fix in CegoSystemObject::createSystemSpace, id values for bustat
table must start with id 1 instead of id 0, otherwise, bustat
information retrievel fails or may result in a core dump
( select * from $bustat )
- Added performance fix for CegoQueryHelper::decodeFVL, since the
tuple context information is already from the method called, the
tid, tastep and ts parameters have been remove from this method.
This saves some decoding time
- Please note, that version 2.28.x makes datafiles from older versions
incompatible.
An upgrade requires a xml tableset export of existing data and a
restore after succesful upgrade
- 2.28.x also contains many code cleanup fixes and some fixes for
btree handling.
- Fix in CegoTableManager::createBTree, in case of an exception
during build up, the allocated have to be cleanup up. For this the
a rollback method was introduced in class CegoBTreeManager.
Fix in CegoTableCursor, invalid btree objects have not been ignored
- Many adapations to make cego full 64bit ready also in combination
with MSYS2 / MINGW64. This resulted in change of many variables
from type long to type unsigned long long (type long is just 32 bit
for Windows ) With an appropriate MSYS2 / MINGW64 installation,
cego compiles proper and runs stable now.
Many thanks to the MSYS/MINGW developers for their amazing work !
- Several changes from type int to type unsigned long long
- Fix in CegoTableManager::deleteDataTable ( renamed to
deleteDataTableEntry )
Since we allow now parallel updates, the method must check if the
target tuple has already been touched by another transaction.
Otherwise, invalid double entries could occur in case of concurrent
updates on the same tuple.
If a concurrent transaction is detected, the method returns false.
This return value is used by the updateTuple method to decide,
if the subsequent insert operation must be performed.
- Since it is not enough jut checking the tuple header info for
update deletes, a record locking has to be added to avoid duplicates.
In this sense, record locking for setTupleInfo method call ( used
in CegoTableManager and CegoTransactionManager ) was added. For
this, the lockRecord and unlockRecord method have been reactivated
in CegoLockManager class.
This lock avoids, that in case of concurrent tuple updates duplicate
tuples are produced by an update.
- Fix in configure.ac to find lfcbase and lfcxml and for FreeBSD

tables the evalTableReferences method has to be called, otherwise
attributes for system tables can not be accessed
- Add dbCheck for Fetch & Cache ( check047 ), all base checks are
run now with querycache ON and OFF
- Fix in CegoSelect::nextTuple, the cache schema was not set up
properly, if nextTuple was just called with empty jfl. This happens
in case of procedure cursors, ( CegoProcFetch ), where the field
value list is for all method calls empty
- Fix for CegoExpr::getAggregationList(), missing break operations
in switch block. This bug might lead to error messages regarding
aggregation queries like
CGCLT > select sum(a) + 0 from t1;
Error : Invalid expression sum(t1.a) + 0 for aggregation
- Modification for admin command set tsroot. Also the base path for
all defined datafiles is set now to new tsroot
- Fix in CegoBTreeCursor and CegoBTreeManager. Several conditons
have been changed from fileId && pageId to fileId || pageId
This bug may results in invalid btree objects in case of btree
spawn over several datafiles ( the pageId might be 0 in the next
file )
- Fix in CegoGroupSpace::insertTuple, the grouping tuple has to be
searched using getTableAlias instead of getTableName, otherwise the
following query returns wrong results
select count(*), a from t1 group by a; --works
select count(*), a from t1 tx group by a; -- broken
A check for this has been added in dbcheck suite

lfcbase:
- Improvement for ListT template class. The end of the list is now
stored int _listEnd variable. This improves Insert performance,
since the end of the list can immediately accesed instead of tracking
through the whole list until the end is reached.
- Patch in ThreadLock, the mutex for lock statistics has been
removed, since there is no need for synchronization. Also errors
have not been checked for the pthread_rwlock_wrlock, which might
cause some deadlocks.
cego:
- Ugly bug fixed in CegoObjectManager::releaseDataPtrUnlocked.
The logical operator && must be replaced by ||, otherwise fix leak arises
- Fix in CegoSelect::nextTuple for query cache to avoid, that queries
including system tables are cached.
- Error message fixes in CegoXPorter
- Introduced bufferpool distribution rate information in show pool output.
This indicates, if the buffer pool is used in a balanced way.
The behaviour can be changed with the BUFFERPOOLHASHKEY parameter.
The list pool command now receives the pool information in several
chunk messages. This allows to print also very large buffer pool
configurations
- Introduced BUFFERPOOLHASHKEY as a database tuning parameter. Based
on this parameter, the corresponding bufferpool slot for a fileId,
pageId tuple is calculated. Depending on the configured datafile
size, it might be useful to adjust this parameter
- Cego Tera Test started. Approach is to load about 1TB of random
data through the whole stack ( via cgblow ). Actually we are running
with 19 parallel processes loading concurrently 4 different tables.
Estimated date to achieve TB-Size is in about one month.
- Changed command line argument --nolockstat to --lockstat. So the
default value is lockstat disabled, since this has impact to the
database performance
- Modification of hash function in CegoBufferPool to achieve a
better distribution for large buffer pool configurations

- Version passed concurrent load test with 10 million concurrent
operations ( random insert, update and delete on one table with 2
processes )
- Fix in CegoFileHandler::allocatePage, In case of page exceed with
appendMode = true, a second try is done with appendMode = false
- Small fix in CegoObjectManager::reorgObject, ref page id information
for append mode is set to new last page id
- Small fix in CegoSelect::filterRefs, allow expressions with constant
values ( getAttrRefList= 0 ) in aggregation
- Locking improvements for delete and update operations.
All delete operations are done now via transactions ( introduced
CegoTableManager::deleteDataTableAtomic ). This allows to use a
shared lock as the table lock for using the table
(CegoDistManager::deleteLocalDataTable and
CegoDistManager::updateLocalDataTable )
As a result, a table can be accessed in parallel during a ( long
running ) delete operation on the table( e.g. delete from table).
E.g. select count(*) from table will not block anymore, rather
indicates the remaining number of tuples in the table.
This modification is still under investigation and must verfied
( also in combination with btree/index objects on the table )
- Fix in CegoBTreeManager::deleteBTree, the relevance value was not
calculated correctly
Fix in CegoQuery, cache invalidation is done before query operations.
Otherwise, if the query is aborted, an exception is thrown and
the cache is not cleaned
- Small modifications on cgblow load simulation client
- Changed locking for delete an update operations to exclusive due
to concurrency prpblems with btree operations
- Added page locking to AVLIndexManager and AVLIndexCursor
- Improvements for locking done. Since locking is done on page level,
Insert and delete operations can be done now in parallel . For this
locking had to be introduced in CegoBtreeManager::insertBTree and
CegoBTreeManager::deleteBTree
Further performance path for grouping queries in CegoGroupSpace.
Since the current grouping key is stored now in the class variable
_groupSchema, some expensive list copy operations could be avoided.
This improves performance for about 4%.

databases/cego: 2.26.2 -> 2.26.7
- Improvements for query execution plan retrieval
- Fix in CegoOutput for multline format
( e.g. execution plans have been cut off )
- Performance patch in CegoTableCursor::setup. The getObjectListByTable
method was called every time, when the attribute condition has been
changed. Since this operation is pretty expensive, it was useful
to cache the retrieved index/btree objet in a local class variables.
This change results in significant query speedup for joins, where
the table cursor has to be setup very often
- Small fix in CegoAction::readChain, treating backslashes for
quoteEscapeFlag=false was commented, reactivated
- Small fix in CegoMain, default for csmode changed to value "ID"
- Fix for CegoBtreeManager::insertBTree. Duplicate handling did not
work correctly, if CegoBTreeNode::addValue returns false ( node is
full ) with a duplicate detection, we also have throw exception.
Otherwise the node is split and a duplicate is added.
- Performance improvement for nested queries ( exists select,
in select). The tablecursor for the select statement is not
released and reallocated for subsequent queries ( in CegoQueryHelper,
the select handle is reset with argument false ) This has required
a different locking strategy for the cursor object in CegoDistCursor.
The cursor object has explicit to get in use, if the nextTuple
method is called the first time.
- Added online help for query cache and table cache in cgadm
- Added further performance fix for aggregation queries in CegoExpr
and CegoQueryHelper. The aggregation list for CegoExpr now is stored
in a class variable and is just evaluated the first time, it is
retrieved. In the method CegoQueryHelper::aggregateTuple, the
increment calculation of the count aggregation has been changed
from memcpy calls to direkt pointer arithmetic
- Performance fix has been done for record locking. In many cases,
row locking could be avoided, since an appropriate locking is ensured
on data page or object level. This brings another significant
performance improvement.

- Fix in CegoBufferPool::calcHas and CegoBufferPool::calcSegement
For large file id's the integer range for the hash key might be
exceeded, which lead to wrong address calculation.
The hash key now is calculated in long based values
- Introduced server mode with same behaviour as daemon mode, but
no child process is forked and server can be terminated with Ctrl-C
- Small formatting fix in CegoOutput
- Fix in CegoDistCursor for inner and outer joins
Inner or outer joins with additional where condition might return
incorrect result set since the condition was just evaluated inside
the join.
To correct this, the WHERE condition is also checked via evalCondition.
This required also a fix in the evalCondition method.
- Added multi segment support to CegoBufferPool. Since the pool is
divided now into several memory segments, this allows larger buffer
pool configurations.
- Improvements for output formatting regarding string functions
(cegoFunction::getReturnTypeLen). Size of required column field size
is now calculated, so the outlook looks more pretty
- Added hints from David Binderman in CegoAction::backChar and
CegoBufferPage::printPage ( changed pointer comparison to avoid

- Next fileId (CegoXMLSpace::nextFID ) calculation now analyses the
existing fileId and uses the lowest available. The MAXFID attribute
in the database xml file is no more used. This avoids, that file
id exceeds in case of frequent creation and removement of tablesets.
- Some format correction in CegoAdminHandler
- Increased parameter FILMNG_MAXDATAFILE to 10000 and
TABMNG_MAXTABSET to 500
- Optimization added in CegoDisCursor::distSetup(CegoAttrCond)
If the native table cursor could not set up either FULL or PART, the
table cursor retrieved all available rows from the corresponding table.
In this case, the table also can be cached to improve subsequent
queries for this table. This fix is relevant for queries like
select * from t1 where b like '%X%', since the like condition
cannot be used by the table cursor

might lead to locking problems.
Since the query is reset after evaluation, query caching is no more
useful. This must be treated in an advanced way.
- Further patches in CegoTableManager::deleteDataTable,
CegoFactor::evalReferences and CegoSelect::nextTuple for advanced
query cache handling. All patches have impact on queries of the form
DELETE FROM t1 WHERE a IN ( SELECT ....)
