- Fix in CegoFunction::clone, also if _exprList is empty, the function
must treated and cloned completely including table manager reference.
Otherwise, for user defined function with no arguments which are used
in views will throw an exception
- Change in CegoJDBCInfo for table list retrievel. This JDBC meta
information command is not split to tab and vie for dedicated
retrievel of table and view objects
- More work has been done regarding clean shutdown of the
database / tableset stop while busy db sessions still exist.
For this, CegoDistCursr desctructor method has been stabilized,
so no exception is thrown. Otherwise, double memory freeing of
cursor resources might occur which results in a crash
- In CegoTableManager::stopTableset, relocated the setTableSetRunState
method above and added a sleep of DBM_LOCKDELAY. This gives hanging
db threads a chance, to terminate save
- Changed CegoDatabaseManager::useObject method to take pointer to
CegoTableManager as an argument instead of threadId. The tablemanager
is used to support thread termination in case of lock delays
- Fix in CegoTableManager::createBTree to catch exclusicve useObject
timeout before committing btree. In this case, the already created
btree object should be deleted. Fix added in CegoClient to active
abort interrupt also during tuple fetch
- Added function getcount to retrieve current counter value for
a specific counter
- Fix in CegoLogManager::stopLog, the log handle must NOT be deleted,
otherwise, a subsequent startLog and logAction method will result
in a dump. This effect has been observed while importing a single
table ( via xml import ) which failed, if the table already exists.
In this case, no checkpoint is written and log handle i no more
valid. A subsequent modifying db request then results in a core
dump.
- Fix in CegoAttrComp for equal, lt and gt operators.
The compMode ATTR was not treated correctly in a way, that the
attrDesc part was not evaluated. This might lead to missing attr
cond entries for sophisticated queries.
A verify check ( verify008 ) has been added to check this case
Author: Björn Lemke <lemke@lemke-it.com>
- Fix in CegoDistManager::renameLocalObject, before renaming the object,
it has to be checked, if the new object name is already in use
- Fix in CegoXPorter::readIndexObject, index schema expects tablename
instead of indexname.
As a result binary and plain imports with index objects have failed.
- Fix in CegoDistManager::startTableSet, the current lsn has
to be setup before performing the cleanup option. cleanup uses
bufferFix which might result in a checkpoint. For this the current
lsn has to be setup
- In CegoQuery, added execSchema which is copied for each execution
call from _schema ( to have a virgin schema definition ). The
execSchema then is enriched in the appropriate way. For the insert
query, an addExprList variable was decleare to store the addition
needed expression to complete the insert value list ( instead of
adding it to _exprListArray ). After performing the query, the
allocated and inserted expression have to be deleted. This
implementation seems to be more useful for procedure based queries,
where the intiantiated CegoQuery object is executed multiple times
- In CegoDistManager, reload message for views, procedure and trigger
is avoided now ( since this occurs for each db thread during startup )
- In CegoAttrComp::setup(ListT** pJoinBuf, int offset) the _isSetup
flag was not set to true for the posSetup case. This might lead to
invalid error message. See https://www.lemke-it.com/litexec?request=pubnews
for details
- Fix in CegoGroupSpace::getValueForAgg, The return value
( of type CegoFieldValue ) must be converted to a local copy,
since the reference to the bufferpool might be invalidated
- Added format correction in CegoField::castTo for case VARCHAR to
FIXED. In case of string values without leading zeros ( e.g. .345),
leading zero is concated.

lfcbase:
- Added HashT::getRangePos and HashT::RemovePos for more efficient
hash array manipulation
cego:
- Fix in CegoQueryCacheEntry::cleanCache, reset of all relevant
variables. Furthermore, in CegoQueryCache methods, remove from
hasharray is checked for return code true
- Usage of new HashT methods ( getRangePos and RemovePos ) for
CegoQueryCache to remove entries from query cache array more efficient
- Fix in CegoFactor::evalFieldValue(), for case CegoFactor::QUERY,
the fetched value must be saved to a local copy, otherwise the
buffer could be overwritten by the subsequent nextTuple method call
to complete the query for query cache. As a result, wrong values
are returned in case of heavy buffer cache relocation.
Also update databases/cego: update 2.47.1 -> 2.47.2
cego:
- Fix in CegoQueryHelper::checkIndexForPredicate, wrong tabSetId
was used for getObjectListByTable, must be table specific
cegobridge:
- In method void MySQLAction::storeVarcharType, dimension value was
doubled, since MySQL calculates visible length for varchars and
cego length in bytes. So for multibyte character encodings, length
might exceed ...
- Rework of new hash array based query cache.
The new introduced methods HashT::FirstInRange and HashT::NextInRange
are used to find an appropriate hash array slot to replace entries
in an occupied array.
- Added cego command line mode setpwd to setup user password
for offline database
databases/cego: update 2.46.8 -> 2.47.0
lfcbase:
- Introduction of template class HashT
cego:
- Integration of HashT into QueryCache for faster access of cached
query entries
- Fix in CegoClient and CegoAction for comment parsing. Comment token
in string are treated now. For this, a new method
CegoQueryHelper::skipComment has been introduced
- Improvements done for query cache handling
( more support for nested queries, stabilization fixes )
Submitted by: Björn Lemke <lemke@lemke-it.com>
- Added fix in CegoTableManager::createBTree
For btree value extraction, we also have to use
valueFromSchema(tableSchema, btreeSchema)
Otherwise, in case if inverted index attributes, the values are
not extraced correctly
Example:
create table t1 ( a int, b string(10));
insert into t1 values ( 1, 'alpha');
create btree b1 on t1(b,a); -- inverted, value for a would be
not setup correctly
Submitted by: Björn Lemke <lemke@lemke-it.com>
- Fix in CegoObjectManager / CegoDatabaseManager added.
The checkTableSetRunState method has been moved to CegoDatabaseManager.
This ensures a single point of check definition.
In the previous version, tableset RECOVERY mode was not treated for
useObject, unuseObject and objectExists method calls which might lead to
crash recovery abort.
Submitted by: Björn Lemke <lemke@lemke-it.com>
- Fix in CegoExpr::evalField, fixed dimension was still not handled
here for ADD and SUB cases
- Added error msg improvement in CegoProcBlock
- Added MAXDELETEPAGE parameter to show parameter admin command
- set default checkpoint value for new defined tablesets
- added function check in CegoFunction::evalFieldValue to ensure, this is
not a procedure without return value
- Fix in CegoTableManager for table altering. No type conversion
allowed with alter modify and no length shrinking
Submitted by: Björn Lemke <lemke@lemke-it.com>
devel/lfcxml: update 1.2.11 -> 1.3.0
databases/cego: update 2.45.35 -> 2.46.0
databases/cegobridge: update 1.5.4 -> 1.6.0
Please note: database updates from 2.45.x to version 2.46.x require
a xml tableset export and import, since table structure information
has been changed!
lfcbase:
- Added template class GraphT for dependency graph implementations
- Fix in BigInteger::mul and BigInteger::div, signing was not treated
( e.g. -12 * 12 => -144 ( was 144 ) )
lfcxml: get in sync with lfcbase
cego:
- Added fix in CegoViewObject::getId. Since it cannot be decided,
if the underlying query result has been changed, we have to
throw MOD_QUERY_ID
- Another query cache fix in CegoFunction:getId, rand and liob
functions have been added to throw MOD_QUERY_ID exception, since
for those function it can not be ad hoc decided, if the result is
modified
- Added type dimension information for CegoField class. This enables the
database to define length and dim information for fixed and decimal
data types. For this the syntax has been expanded. Instead of storing
RESERVED_BTREE_FLOATLEN for btrees on fixed or decimal columns,
the specified length information is used now.
Submitted by: Björn Lemke <lemke@lemke-it.com>
- Added noinit option to cgadm tableset start command. With the
noinit option, the configured init file will not be processed after
tableset startup, otherwise this will be processed now ( if any
configured ) All output messages are written to main log file.
- Redirected output for CegoAction and CegoOutput added to print output
to logfile. This is useful in case of tableset init file, where
several SQL action could be performed
- Fix in CegoAction::execSetCounter, new value must be checked for
null value and if so, set counter to 0. The bug caused a seg fault ..
Submitted by: Björn Lemke <lemke@lemke-it.com>
- Improved runstate handling in CegoDistManager
- Further fix in CegoPredDesc::getFieldList, case CegoPredDesc::NULLCOMP,
getFieldList method call added for pExpr1,
in CegoPredDesc::setFieldListArray method calls added for
_pC and _pNotPred. For this, setFieldListArray method has been
introduced in CegoCondDesc. This fixes should complete case
cond handling e.g. for aggregation queries.
check097 has been expanded for this
Submitted by: Björn Lemke <lemke@lemke-it.com>
- CegoObjectManager has been modified to check tableset run state
for several methods. For this, method
CegoObjectManager::checkTableSetRunState has been introduced.
- Added check in CegoDatabaseManager::objectExists to verify, if
corresponding tableset is online. So instead of "invalid object"
exception, a tableset offline exception is thrown, which might be
more useful
Submitted by: Björn Lemke <lemke@lemke-it.com>
- Added case-cond support for aggregation queries
- Fix in CegoCaseCond::evalField, all expression are evaluated now
and are checked for type mismatch. Expressions must return the same
type, otherwise this might lead to value evaluation problems. This
fix also leads to fix in CegoFieldValue::getDim() and CegoFactor::evalField
since now getDim ist used for field length specification which is
also compared by CegoCaseCond::evalField
Submitted by: Björn Lemke <lemke@lemke-it.com>
- Fix in CegoTableManager::insertDataTable, before call
getObjectListByTable, type must be checked ( must be CegoObject::TABLE
), otherwise ( for system objects ) not found exception arises.
This error may appear with the admin commands begin backup and end
back ( stat information is written to bustat system table )
- Added format fix to CegoAction::formatTableInfo, to treat very
long object names, max name length of all corresponding objects is
now calculated and output is printed in appropriate format
- Change in CegoAction::execProcCall and CegoAction::execFuncCall,
procedure/function arguments are evaluated and cast in this methods
now. This is needed, to support string to clob casting for procedure
arguments. As a consequence the CegoProcedure::execute method has
been changed to receive ListT instead of ListT.
Submitted by: Björn Lemke <lemke@lemke-it.com>
- Typo fix in CegoTerm::evalField and CegoExpr::evalField
- More rework on CegoFieldValue for improved cast handling
( especially on fixed values )
Submitted by: Björn Lemke <lemke@lemke-it.com>
databases/cego: update 2.45.19 -> 2.45.23
lfcxml:
- Sync patch for MinGW package build
cego:
- Fix in CegoFieldValue::castTo, case VARCHAR_TYPE to FIXED_TYPE,
plain integers have not been accepted. check091 added for this
- Fix in CegoTerm::evalField and CegoExpr::evalField, type and
length calculation must correspond to cast logic in CegoFieldValue
( corresponding operators for mul, div, add and sub )
- Fix in CegoProcVar::setValue, a castTo has been added to cast to
appropriate target type
Submitted by: Björn Lemke <lemke@lemke-it.com>
- Fix in CegoAction::insertArg to check for duplicate attribute
specification in insert statement, e.g.
INSERT INTO t1 ( a, a ) VALUES ...
Submitted by: Björn Lemke <lemke@lemke-it.com>
- Fix in CegoClient for treating interactive input. Ctl-D input
lead to segmentation fault, if used in multiline statements.
- Patch in CegoAction::formatTableInfo. For size calculation of
btree objects, null value must be used instead of INVALID, otherwise,
wrong values are indicated during btree build
- Patch in CegoLogManager::switchLogFile, we first have to switch log
file and then change the status to OCCUPIED. Otherwise, the logfile
archiver ( CegoLogThreadPool::shiftRedoLogs ) might access occupied
logfile in parallel. Since this is a different thread and File::open
seems to be not thread safe, bad things might happen ...
Submitted by: Bjoern Lemke <lemke@lemke-it.com>
- Fix in CegoBtreeManager for duplicate null handling. The corresponding
btree value has to be checked to be null. For this, the method
CegoBTreeValue::isNull has been introduced
- Fix in CegoFieldValue::negate, for FIXED_TYPE values, trailing
zeros have to be treated. Otherwise, select null - a from t1 where
a = 0.10 will result in 0.1
- Patch in 'update with return' clause. It seems to be useful, that
in combination with return, update should return after first matching
tuple providing the updated tuple in the return clause. So the
values for the tuple can be stored in procedure variables.
create table t1 ( a int, b string(30));
insert into t1 values ( 1, 'DONE');
insert into t1 values ( 2, 'DONE');
insert into t1 values ( 3, 'WAIT');
insert into t1 values ( 4, 'DONE');
insert into t1 values ( 5, 'WAIT');
update t1 set b = 'DONE' where b = 'WAIT' return :a = a;
Just the tuple with a = 3 is update and the value of a is returned
in the procedure variable :a
- For update with return statements, added the on first option.
Since the return variable can only store one return values, this
option specifies, if the update should return after first tuple or
if all matching tuples should be updated.
- In CegoMain, changed separator token for tsdef from ":;" to "=",
since for mingw configurations, absolute path handling was broken.
This resulted in adapations for mkdb and cgmkdb scripts.
- Fix in CegoObjectManager::getObjectListByTable, if object does
not exist, an exception is thrown now.
This resulted in a fix for CegoQueryHelper::checkIndexForPredicate,
where now the table alias has to be mapped to the correct physical
table name ( via coList as a new method argument )
- Fix in CegoAttrDesc::evalTableReferences to treat alias objects in joins
- Grammar expansion to support inner/left outer/right outer joins
without a condition. This might be useful for specific join order
to use appropriate table indices ( see dbcheck/check088.sql )
- Fix in CegoQueryHelper::checkIndexForPredicate, index evaluation
for alias objects was still not treated
- Fix in CegoDistCursor::getPlan and CegoAction::getJoinPlanString
to cover execution plan for alias objects
Submitted by: Björn Lemke <lemke@lemke-it.com>
- Fix in CegoBTreeManager, the allowDuplicateNull flag was not
treated any more. The duplicate handling has been moved from
CegoBtreeNode to CegoBtreeManager
Submitted by: Bjoern Lemke <lemke@lemke-it.com>
- Fix in CegoSelect::setVIewCond, a view condition id has to be
calculated which is later used for getQueryId(). Otherwise, wrong
query cache entries are used in case of views with outer conditions
- Added method CegoBTreeNode::verifyLeafFull for full btree
verification in a sense, that each btree value is compared with the
corresponding table data entry via datapointer reference
- Improvement in CegoAdmAction for input handling. Used the same
methods for nextChar and friends as in CegoAction
- In CegoXMLSpace, changed access methods for mediator, primary and
secondary in a way, that the default value ist the current hostname.
In this case, no attribute values are set up. This reduces complexity
and avoids to change the entries manually, if the hostname changes
(do not edit the database xml without any deeper knowledge).
Submitted by: Bjoern Lemke <lemke@lemke-it.com>
databases/cego: upgrade 2.45.5 -> 2.45.6
lfcbase:
- In configure.ac added check for darwin. This is required, since
for File::flush implemention, darwin rather requires a fcntl call
with option F_FULLFSYNC instead of fsync ( see OSX man page for
fsync )
cego:
- Added command line option --fsync to enable physical disk synchronisation
for logging and checkpointing. This options slows down database
significantly but ensures consistent data in case of an operating
system crash
Submitted by: Bjoern Lemke <lemke@lemke-it.com>
- Fix in CegoQuery::execute for INSERTBYSELECT_QUERY case.
Since the selected tuples are clustered ( MAX_CLUSTERED_INSERT) we have
to create a local copy for the corresponding field values.
Otherwise, tuple information could be invalidated by relocated
buffer pool pages
- Fix in CegoFieldValue::fastComp, the castTo method calls for t1
and t2 have to be switched, since first ist has to be checked to
cast to native btree datatype ( used in CegoBTreeCursor::traceLog,
inRange and fullMatch )
example:
create table t1 ( a int, d datetime);
create btree b1 on t1(b);
select a from t1 where b = '12.07.2019'; -- should be casted
-- from string to datetime
- Code cleanup to avoid warnings with -Wswitch-enum
- In CegoClient, added input data check via File::hasData ( available
with lfcbase 1.14.0 ). Now, pipe input is autodetected, so the
command line argument "--pipe" has been removed
Submitted by: Bjoern Lemke <lemke@lemke-it.com>
- Treated alias insert queries with empty schema, e.g.
insert into a1 values ( 1, 'XXX');
- Some patches added for alias management to allow alias defintions
as a subset of the original table, e.g.
create table t1 ( a int, b string(10), c string(30))
create alias a1 on t1 ( a as ax, b as bx);
This has required some fixes in CegoAliasObject::mapSchema and
CegoQueryHelper::mapFLA
Submitted by: Bjoern Lemke <lemke@lemke-it.com>
- Added table alias feature to grammar definition. Table aliases
allow alternate table name and attribute name definitions for a
table ( create alias ... )
- Added classes CegoAliasObject and CegoAttrAlias for table alias handling
- Implemented base semantic actions for creating, listing and
describe alias objects ( still no usage )
- In CegoDistManager::registerObjects, added registration for fkey,
check, trigger and alias
- Added alias mapping for insert, update and delete queries (
CegoQueryHelper::mapAliasPredicate still to implement )
- Basic alias mapping for select works, here's a sample SQL script
drop if exists table t1;
list alias;
desc alias a1;
drop if exists alias a1;
create table t1 ( a int, b string(30));
create alias a1 on t1 ( a as ax, b as bx );
insert into a1 ( ax, bx ) values ( 1, 'XXX');
insert into a1 ( ax, bx ) values ( 2, 'YYY');
insert into a1 ( ax, bx ) values ( 3, 'ZZZ');
select ax from a1;
- More work on table alias handling. Now works with more sophisticated
select queries ( e.g. select ax from a1 aa where aa.ax = 1; ) For
this, some fixes had to be done in CegoContentObject, since the the
table alias attribute ( _tabAlias ) was not setup in constructor
and other methods
- Added alias and trigger xml export and import feature ( trigger
xport was still not implemented ) Fix in CegoDbThread::loadObjects
for trigger reload, instead of triggerList.Next(), triggerList.First()
was called, which result in an infinite loop in case of existing
trigger objects
- Added trigger and alias object handling to CegoXPorter binary
export and import
Submitted by: Bjoern Lemke <lemke@lemke-it.com>
- Some improved exception handling in CegoTableManager::checkIntegrity
( more detail information about violated object )
- Code cleanup CegoTableManager, drop/create/alter operations inside
a transaction no more allowed
Submitted by: Bjoern Lemke <lemke@lemke-it.com>
- Further recovery fix in CegoTableManager::insertDataTable In case
of an insert exception ( e.g. duplicate pkey ), a checkpoint is
forced now after deleteData to ensure file consistency
In CegoObjectManager::insertPageData a second checkpoint is forced
after data copy, if a previous checkpoint has occured. Otherwise
this insert might be ignored during recovery because of lower LSN
- Fix in CegoBTreeManager::checkDuplicate, the check for uflag (
returned CegoBTreeNode::valueExists ) to check for high value is
not enough if, entries have been deleted from node.
Instead, all subsequent pages have to be checked until a value higher is found
- Introduced CegoBufferPool::getCPCount() to return to current
checkpoint count. This method is used by CegoTableManager,
CegoObjectManager and CegoTransactionManager to decide, if a
consitency checkpoint is required
- Version passed checkCrashRecovery with the following parameters
NUMRUN=100
DOTRANSACTION=-dotransaction
ARANGE=10000
AINTERVAL=500
ACOUNT=30000
PRIMARY=primary
POOLSIZE=191
All relevant checkpoint situations have been observed over all run
Submitted by: Bjoern Lemke <lemke@lemke-it.com>
- Fix added in CegoTransactionManager::commitUpdate, btree must be
inserted with insertBTreeWithCommit
- Fix added in CegoTransactionManager::getCrashAffectedTables,
schema entry must be searched with Find(CegoField(Chain(),
SYS_RB_TABLE))
Submitted by: Bjoern Lemke <lemke@lemke-it.com>
- Fix in CegoRecovery:::recoverCurrentTransactionLog, for LOGREC_INSERT
and LOGREC_DELETE, the corresponding index have to be invalidated
with CegoTableManager::invalidateIndexForTable. This logic was
already implemented but removed in context of more sophisticated
transaction handling ( patch 2.39.11 and around )
- Small fix in CegoObjectCursor constructor, changed _isEOC = false
to _isEOC = ( pageId == 0 ). This causes getFirst to return false
in case of truncated objects ( can occur for RBSEG objects )
Submitted by: Bjoern Lemke <lemke@lemke-it.com>
- Fix in CegoAction::readChain() to support "\r" escape character
Fix in CegoBTreeCursor::getFirst, in case of pAttrCond = 0, getNext
has to be called if current leaf page is empty, otherwise cursor
trace is incomplete ( just used for CegoDistManager::verifyTable )
- Fix in CegoBTreeNode::getChildPage, parameter traceMin has been
introduced, which is needed to trace btree with
CegoBTreeManager::deleteBTree.
Otherwise, it might happen that non-unique btree objects are not found
Submitted by: Bjoern Lemke <lemke@lemke-it.com>
- Removed legacy method CegoAggregation::setInit/isInit
- Fix in CegoQueryHelper::aggregateTuple, since the field value
reference for aggregation field value might be no more valid during
the aggregation run, a local copy is created via
CegoFieldValue::getLocalCopy.
Submitted by: Bjoern Lemke <lemke@lemke-it.com>
- Added method CegoClient::treateEscape to handle escacpe charaters
in command strings for interactive and batch mode ( newline, carriage
return und tab )
- Further optimization in CegoFunction::getReturnTypeLen, if the
length argument in left, right substr function is a constant, this
value is used for schema definition, otherwise the length of the
source is used. Example:
select left(a,3) from t1 => length 3 is used for schema
select left(a,b) from t1 => definition of a is used for schema
Further optimization done in CegoSelect and CegoAction for schema
evaluation.
Submitted by: Bjoern Lemke <lemke@lemke-it.com>
- In CegoSelect::evalSelection, optimization provided in a way,
that schema is not evaluated explizit anymore. Rather the previous
analysed schema ( prepare method, _evalSchema ) is used. Since for
dynamic field length, the resulting schema must be estiamated, this
approach is ok.
- Fix added in CegoFunction::getReturnTypeLen, evalFieldValue for
expression values could fail, since FLA ist still not set up. For
this case, now the cont value RETVAL_LEN is returned as an estimation.
Submitted by: Bjoern Lemke <lemke@lemke-it.com>
- Added fix in CegoAttrComp::setup, _posSetup variable was not setup
correctly for case BTWN / VALUE2VALUE which might lead to invalid
join array access.
Submitted by: Bjoern Lemke <lemke@lemke-it.com>
- Added fix in CegoExpr::evalField and CegoTerm::evalField to provide
correct result type. This is required for fastserial protocol usage.
- Also added fix in CegoFieldValue::operators +-*/ to cast to the
largest value
Submitted by: Bjoern Lemke <lemke@lemke-it.com>
- Fix in CegoTableManager::deleteDataTable, before resolving external
table references via evalExtTableReferences, the subquery must be
prepared, to resolve local attributes first
- Optimization added in CegoBufferPool::bufferFix. If there is no
available slot in the bufferpool, a checkpoint is forced for the
corresponding tableset ( already implemented ). Now if still no
available slot, we force checkpoint for all other online tableset
of the database. This might be useful, if the bufferpool is heavily
occupied by other tablesets with dirty pages.

databases/cego: update 2.39.15 -> 2.39.16
lfcbase:
- Introduced new method File::flush to force synchronization of data to disk
cego:
- Fix in CegoObjectManager::insertPageData, new data entry is checked
now for maximum available space in page. This is done if a new
data page has to be allocated and the data entry still fits not
into page
- Added File::flush method to CegoLogManager and CegoFileHandler
to synchronize log data and datafile data to disk
Submitted by: Bjoern Lemke <lemke@lemke-it.com>
- Fix in dbcheck/expimpcheck, test plan was not set up correctly
In CegoXPorter and CegoExpImpStream, row export information was
added again to indicate overall row export for each table
- Fix added in CegoDbThread::serveRequest ( GETBLOB and GETCLOB case ) and
CegoTableManager::getBlobData / getClobData chunkSize calculation. The
existing calculation did not treat every boundary case.
