databases/cego,devel/lfcbase: 2.52.2 -> 2.52.4, 1.21.3 -> 1.21.6

lfcbase:
- To support several keyboard layouts, changed some window control
  sequences from Cntrl-Key to ESC key
- Added virtual method hasData to Pager class. The method must be
  implemented to indicate, if an execution returns a result set. If
  no result set is returned, just a message box is shown and edit
  mode is left ). This seems to be useful for DML queries ( insert,
  udate, delete, create, drop, ...)
- In Pager class, added buffer scrolling in editor part. Preparation
  started for Pager command history management
- Added history feature to Pager class. Command history can be loaded
  and saved with readHistory and writeHistory methods.
  Navigation through command history in Edit mode with Cntrl-P and Cntrl-N

cego:
- Adaptions made for pager and pager history feature

databases/cego: update 2.51.9 -> 2.25.2, devel/lfcbase: 1.20.1 -> 1.21.3

lfcbase:
- more patches for the Pager class
  Removed init_color with custom color for select cursor since the
  custom color seems to be poor supported for curses. Fixes added
  to Pager::writeFooter
- edit-feature in Pager (must discuss this with Bjoern 8-)
- ignore SIGINT in Pager
- change from unsigned long long to long long value in Datetime class
- pattern search feature for Pager class

cego:
- Small fix in CegoBufferPool.h
- CegoClient adapted to new Pager API
- Queries now can be interrupted with Cntrl-C also in pager mode
- adapt to Datetime long long values ( e.g. date2str from int to long long )

lfcbase:
- Rework of Pager class, which is a API change

cego:
- Made some adaptions for reworked lfcbase Pager class
  rows with multiline entries are more readable

13:16 Kurt Jaeger (pi)  Author: Björn Lemke

databases/cego: update 2.51.7 -> 2.51.8

- Added check script check119.sql to verify grammar expansion
  for stored procedure condition
- CegoAction::procArg1() and CegoAction::procArg2() to check
  duplicate parameter names
- Added check118.sql to demonstrate explicit table locking for nested
  delete operation within a cursor loop

12:02 Kurt Jaeger (pi)  Author: Björn Lemke

databases/cego: update 2.51.5 -> 2.51.7

- Fix added in CegoFactor::getAggregationList:
  for case QUERY and case FETCH, the not-supported exceptions
  have been removed, otherwise this leads a useless exception
  in CegoAttrCond::asConjunctionList where aggregations are just checked
- Added grammer change in Cego.def to ensure operator precedence
  for AND and OR condition operator.
  AND has higher precedence if no enclosing braces are given.
  The result for the following queries should be the same
  select * from t1 where a = 42 or a = 1 and  b = 'X' ;
  select * from t1 where a = 1 and  b = 'X' or a = 42;
  select * from t1 where a = 42 or ( a = 1 and  b = 'X' );
- With cego version before 2.51.7, braces have been mandatory to
  ensure operator precedence.
  With the new grammar extension, the AND operator has a higher presedence

08:25 Kurt Jaeger (pi)  Author: Björn Lemke

databases/cego: update 2.51.3 -> 2.51.5

- CegoFactor::evalFieldValue, QUERY case, after query
  evaluation, the parentJoinBuf has to be reset, otherwise an invalid
  reference is used later to CegoSelect::getQueryId. This might result
  in core dumps, if query cache is enabled
- Added querycache verification to db check routines
- Added querycache mode to command line options to set up query cache by batch

databases/cego: update 2.51.1 -> 2.51.3, devel/lfcbase: update 1.19.0 -> 1.19.1

lfcbase:
- BigDecimal::div null value check

cego:
- CegoFactor::toChain to add braces for condition case
- CegoSelect::initAggregation, for sum and avg aggregation, aggregation
  value is initialized with 0 and appropriate datatype ( instead of
  null value ). This leads to numeric result 0 in case of empty result
  sets ( instead of null value )

    af3d489

06:59 Kurt Jaeger (pi)  Author: Björn Lemke

databases/cego: update 2.51.0 -> 2.51.1

- Fix made in CegoDistCursor::distSetup to support FLA setting with
  no cursor condition. This is needed for query plan evaluation for
  nested inner/left outer/right outer joins
  See check114 as a sample

    6e28ea9

16:07 Kurt Jaeger (pi)  Author: Björn Lemke

*/*: update several cego related ports

devel/lfcbase 1.18.11 -> 1.19.0
- Changed Datetime::asLong to return signed long values ( long long ).
  This is needed to support timestamp values before 01.01.1970,
  which are signed negative

databases/cego 2.50.6 -> 2.51.0
- consolidate grammar productions for query conditions and
  procedure conditions
- Since CegoPredicate::CompType has received new type EXPRONLY,
  this requires a tableset export/import for upgrading to this version
  ( for predicate encoding / decoding )
- Several changed in CegoFieldValue to switch from Datetime integer
  type unsigned long long to long long. This is required to support
  datetime comparison for values before 01.01.1970

databases/cegobridge 1.8.1 -> 1.9.0
- adapt to cego 2.51.0

    0fdd0ce

  see check113.sql for samples

    6458a7e

18:25 Kurt Jaeger (pi)  Author: Björn Lemke

databases/cego: update 2.50.3 -> 2.50.4

- Optimization added to CegoPredDesc::match. Matcher is just created,
  if the match method is called, since it might occur, that the
  condition is evaluated be CegoDistCursor via CegoAttrCond
- Fix in CegoAttrComp::getMatcher, there was still missing star
  escape, which has been added to CegoPredDesc constructor. To avoid
  two same pieces of code, CegoQueryHelper::sql2Regex has been
  introduced

    d78a9e6

08:09 Kurt Jaeger (pi)  Author: Björn Lemke

databases/cego: update 2.50.2 -> 2.50.3

- in CegoPredDesc constructor to meet FreeBSD regex requirements
  ( regcomp fails with regex pattern containing concatenated
  star, e..g. ".**" ). So "*" is replaced with ".*"
- code cleanup release

14:06 Kurt Jaeger (pi)  Author: Björn Lemke

databases/cego{bridge}: 2.49.22 -> 2.50.2, 1.7.0 -> 1.8.1

cego:
- Added syntax expansion for group having clause to support
  advanced having conditions, e.g.
  SELECT a, sum(b), max(c) FROM t1
  GROUP BY a HAVING sum(b) > 10 AND max(c) = 100;
- Patch added for 'view condition evaluation' in
  CegoAttrCond::asConjunctionList, CegoSelect::setViewCond and
  CegoDistCursor::distSetup.
- Additional check added to CegoObjectManager to avoid duplicate
  table objects of different type ( e.g. Table t1 and View t1 ). Table
  objects are either native tables, views or aliases.
- For predicate export structure, changed from XML representation
  to native SQL syntax. This requires a dedicated Parser in CegoXPorter,
  which can handle predicate SQL representation, but saves lots of
  code, since all subsequent member classes of CegoPredDesc no more
  need to implement XML representation methods ( constructor,
  fromElement, toElement )
- Added stabilization patches for nested grouping select, e.g. in
  exists subselect. In CegoSelect::reset, for _selectMode == GROUPING,
  grouping space is resetted now properly.
- Added stabilization patches to CegoAction. Load statements for
  views, procedures, triggers and condition are treated regarding
  object allocation/free. These statements are for internal use only,
  so a database user receives a note message now
- Further improvements added in CegoQuery to give more detailed
  error information in case of exceptions
- In CegoTableManager, made some exception message improvements,
  instead of popping last message, the complete message stack is thrown

cegobridge:
- Support added for cego-2.50.x
- Fixes added for modified CegoAction::getSelect and
  CegoAction::getProcedure methods

    a50cd77

08:17 Kurt Jaeger (pi)  Author: Björn Lemke

databases/cego: update 2.49.21 -> 2.49.22

- For several modules, added exception trace information to improve
  error logging in case of any exception
- Patch added for CegoQueryCache::addEntry, getNumUsed added to
  search loop to find appropriate slot. This avoids some needless
  assignments, since used entries cannot be assigned.
- Patch added CegoQueryCache::invalidate. For main loop, a delay
  has been added, to give other threads the chance to claim the lock

    69f948d

10:50 Kurt Jaeger (pi)  Author: Björn Lemke

databases/cego: update 2.49.20 -> 2.49.21

- Patch for CegoFunction added.
  For methods getReturnType, getReturnTypeLen and evelFieldValue
  the following has been added : If proc object is getting used by
  useObject, the following getProcedure call must be catched for
  exception to unuse the object since _pProc is stiil null and the
  object so is not unused by cleanup

    987ed7e

19:14 Kurt Jaeger (pi)  Author: Björn Lemke

databases/cego: update 2.49.16 -> 2.49.20

- Removed lockPool call in CegoAdminThread::srvExportTableSet and
  srvExportTable to avoid lock timeouts during long running exports
- Made some code cleanup in CegoAdminThread ( exception consolidation )
- db thread query history information, added timestamp and cost information
- Introduces new cgadm admin commands
  o queryhist last n
  o queryhist cost n
  to show the query history for all db threads in the db thread
  pool. The last n queries or the most expensive n queries are
  indicated
- Added query history suppport for cgadm screen mode
- CegoAdmScreen to fully support of query history feature
  ( last and full over all db threads ).
- Screen2:Grid schema patches added to satisfy new column alignment
  feature for Screen2
- Fix added in CegoDBThreadPool. CegoAdminThreadPool and CegoLogThreadPool.
  If database hostname is not defined, the corresponding service is served
  on any hostname. This avoids confusion regarding IPv4 and IPv6 host
  configuration ( e.g. on MacOSX Sequoia, java seems to
  handle localhost always as IPv4 127.0.0.1, while on POSIX layer,
  it is mapped to ::1, a bit strange )
- Added new lfcbase Net::serve6 method to db, admin and log threadpool.
  If no hostname is defined in database xml, an IP dual stack
  configuration is set up.

19:44 Kurt Jaeger (pi)  Author: Björn Lemke

databases/cego: update 2.49.11 -> 2.49.16

- cgmkdb utility script:
  allows to set up advanced database parameters
- In CegoXMLSpace::addTableSeDef, added ARCHMODE attribute to
  set archmode to OFF as default
- Added querycache threshold parameter. Just queries with execution
  time greater than threshold value are cached. This leads to a lower
  stressed cache and avoids cache latency for those queries. Threshold
  is given in msec, which seems to be appropriate for now.
- Some memory leaks fixed
- fix cgadm (hang if INTR received while idle)
- Added query history for db threads. Not just the last action is
  indicated via admin command "threadinfo db threadId", but also the
  last n queries processed by this thread. History Length can be
  configured via new cego command line option dbthreadhist

14:29 Kurt Jaeger (pi)  Author: Björn Lemke

databases/cego: update 2.49.10 -> 2.49.11

- Patch added for memory leak in CegoSelect::cleanUp and
  CegoSelect::reset, for both methods, _pCacheList has to checked and
  freed, since for uncompleted queries ( e.g. exists clause ) the
  _pCacheList was still not deleted
- Another fix for memory leak added in CegoFieldValue::getLocalCopy,
  Before allocation, _len has to be checked for _len < STATICFIELDBUF
  and then use _staticBuf, otherwise, the memory is lost

14:34 Kurt Jaeger (pi)  Author: Björn Lemke

databases/cego: 2.49.9 -> 2.49.10, devel/lfcbase: 1.18.7 -> 1.18.8

lfcbase:
- patch to Screen2::Form::handleKey to treat pipe character ( | )
- patch to Screen2::Attribute::setAttrList for refresh window
  after attrlist has been updated
- Change in Screen2::Attribute class.
  The class now provides three layout modes : HORIZONTAL, VERTICAL, OVERLAY.
  In OVERLAY mode, with left and right cursor key it is switched
  to visible attribute list. For this, the Screen2::Attribute constructor
  has been changed

cego:
- For CegoAdmScreen, added QueryCacheInfo to tableset menu
- daptions made for CegoAdmScreen to
  handle lfcbase-1.18.8 API change for Screen2::Attribute

19:23 Kurt Jaeger (pi)  Author: Björn Lemke

databases/cego: update 2.49.8 -> 2.49.9, devel/lfcbase: 1.18.6 -> 1.18.7

lfcbase:
- Added patch in Matcher.cc to support extended regular expression
  (added REG_EXTENDED flag to regcomp call )

cego:
- Added dedicated admin command to show query cache information
  including hit rate ( show querycache for tableset )
  This will replace the querycache information shown with general
  show tableset admin
  command
- Added patch for memory leak in CegoSelect. Within
  CegoSelect::consolidateConjunctionList method, predicate and condition
  instances are created for conjunction organisation. These instances
  have to be registered and freed later within CegoSelect::cleanUp
- Rework of table cache logic, which is still experimental. A table
  filter now can be defined to just cache a specified subset of tables.
  Since table cache is just useful for specific tables with read only
  flavor and medium size, this extension seems to makes sense. Cached
  table rows can be accessed directly without accessing buffer pool
  pages and without decoding. This might accelerate some database
  configurations, where query cache is not appropriate and hot spot
  readonly tables have to access very often and very fast.

    acd64d5

15:08 Kurt Jaeger (pi)  Author: Björn Lemke

databases/cego: update 2.49.7 -> 2.49.8

- Added patches for querycache.
  The CegoQueryCache::addEntry method now is limited to
  QUERYCACHE_MAXTRY tries to add an entry. Otherwise numFail
  counter is increaed, which is monitored for the query cache.
  This should resolve deadlocks in smoother way ( no more lock timeouts )
  in case of other db thread have the requested querycache slot in use.
  For performance reasons, CegoQueryCacheEntry::calcSize was introduced
  to just calculate the entry size in the constructor.
- Added lockId for lock objects in CegoBufferPool and CegoQueryCache

    ad32ab4

11:16 Kurt Jaeger (pi)  Author: Björn Lemke

databases/cego: 2.49.6 -> 2.49.7

- Fix added for CegoXPorter / CegoAdminThread / CegoBufferPool
  to treat locking issue during tableset / table import.
  Since the pool is locked during import ( by new introduced method
  lockPool ), no further locking calls must occur during import.
  For this, log writing is disabled before lockPool is called and
  CegoBufferPool::logIt checks for active log ( via new isActive
  method ) before trying to get a lock.

    aa7dd71

07:52 Kurt Jaeger (pi)  Author: Björn Lemke

databases/cego: update 2.49.4 -> 2.49.6

- Synchronization of tableset admin operations added with this patch.
  In CegoBufferPool, new methods are provided for tableset oriented locking
  ( lockPool and unlockPool ) These methods are used by CegoAdminThread
  to synchronize concurrent tableset admin operations
  ( like stop tableset, drop tableset, export tableset, e.g. )
- Indent format improvements made for select, insert and update queries.
  This is relevant for formatted sql code in stored procedures.

devel/lfcxml,databases/cego: 1.3.6 -> 1.3.7, 2.49.0 -> 2.49.2

lfcxml:
- Patch added in XMLSuite.cc to treat CDATA lookahead correctly.
  Trailing square brackets ( ] ) at the end of cdata caused parsing problems

cego:
- Added missing thread lock information for admin thread list and
  thread stat command ( query + table locks, logmanager locks )
- Added patches in CegoQueryCache to improve locking.
  For the addEntry method, the complete locking logic was
  redesigned to avoid deadlocks

databases/cego: update 2.48.48 -> 2.49.0, cegobridge 1.6.5 -> 1.7.0

- In CegoCaseCond, added getPlanList method to retrieve execution plan
  for nested selects. The planlist then is catched in CegoFactor::getPlanList
- Consolidation done for data types decimal and fixed.
  This version just supports the decimal datatype which originally was
  the fixed datatype. The original decimal datatype was useless.
  IMPORTANT: To migrate to version 2.49, you have to xml export
  the databases and rename the datatype strings "fixed" and "FIXED"
  to "decimal" and "DECIMAL"
- cegobridge needs to be rebuild

14:54 Kurt Jaeger (pi)  Author: Björn Lemke

databases/cego: update 2.48.45 -> 2.48.48

- Fix in CegoAdmScreen::TableSet::TableSet constructor,
  SysUsage field added to indicate correct usage
  for system, temp and app files
- Patch added for transaction handling in CegoTransactionManager::doCommit
  and CegoTableManager::deleteDataTableEntry.
  Just for tuple state COMMITTED, a rollback entry must be created,
  otherwise double tuple delete may occur.
  For tuple state INSERTED, tuple state is just set to OBSOLETE,
  for tuple state OBSOLETE and DELETED, nothing has to be done.
  In CegoTableManager::doCommit, tuple state just has to be set
  to COMMITTED in case of INSERTED tuples
- Elimination of a cout in CegoQueryCache::QueryCacheEntry::cleanCache

    55e6b18

12:39 Kurt Jaeger (pi)  Author: Björn Lemke

databases/cego: update 2.48.44 -> 2.48.45

- Added patches for return on update handling to treat value handling
  in return list. The order in the return list must be stricter,
  otherwise field evaluation via FLA caching in CegoFactor fails.
- returnList has been localized ( new method CegoQueryHelper::localizeFL )
  to ensure correct values after update cursor ist closed.

- Patch added in CegoQueryHelper::evalBetween
  The comparison ( f2 <= f1 && f1 <= f3 ) has changed to
  ( f1 >= f2 && f1 <= f3 )
  This forces a type cast to f1 datatype in case mismatched datatypes.
  This might be useful for queries like
  select a from v1 where a between '30.11.2023' and '31.12.2023';
  where a cast should be done to date time value ( instead of string )

  and microSleep. For this, also input parameter type has changed from
  int to unsigned long

cego:
- Patch added for CegoCaseCond::evalField to eval appropriate datatype.
  If the case condition contains null type this was not done correctly
- Added patch in CegoSelect::evalSchema. At the end of the method,
  schema ids are calculated to provide unique attribute ids for views
- support nested case conditions

  to avoid leaks regarding stored proc object use
  ( this corresponds to the new optimized stored proc handling )

    6b907e1

10:18 Kurt Jaeger (pi)  Author: Björn Lemke

databases/cego: update 2.48.25 -> 2.48.27

- Patch addd for tableset stop procedure.
  With the new optimized stored procedure handling ( CegoFunction module ),
  the object cleanup must be done BEFORE the tableset is finally stopped.
  Otherwise an uncaught exception occurs ( tableset not online )
  which results in database crash after tableset shutdown.
  Several modules have been modified for this
- In CegoFunction constructors, added _pProc = 0 initialization
  for decoding and fromElement constructors. This avoids a set fault,
  in case of database recovery, when a predicate expression
  with user function is dedoded from log file

10:12 Kurt Jaeger (pi)  Author: Björn Lemke

databases/cego: update 2.48.23 -> 2.48.25

- Performance improved for stored procedures.
  In CegoFunction, the procedure handle is now stored after first
  stored procedure call ( instead of freeing the handle and requesting
  it again with the next call )
  So for subsequent function calls, the handle is already available,
  which improves stored procedure execution time significantly.
  As a consequene, code has been added for cleanUp the handle at
  the end of the query ( object is also in use during the whole
  query with CegoDatabaseManager::useObject and must be unused by cleanup )
- Patch added in CegoFunction to avoid useObject leaks

  WIth cgadm the appendmode can be setup ( e.g. enable appendmode for TS1 )
  It may be useful to have enabled appendmode at default for insert
  intensive tableset configurations
- Fix added for CegoAdmScreen in tableset parameter panel.
  Initfile was not setup correctly
  ( null value indicated, should be empty string )
- Changes in CegoAdmScreen::DBThread panel to show long queries
  with new Screen2::Message panel
- Patch added in CegoTableManager::updateTuple,
  reactivated evalExtTableReferences method call,
  since this is needed for update with nested selects,
  where external attributes are referenced
  in combination with enabled query cache
  ( e.g. update t1 set a = ( select a from t2 where t1.b = t2.b ) )

devel/lfcbase,databases/cego: update

lfcbase: 1.18.0 -> 1.18.3
- Opimization in Screen2 to customize screen refreshes
  ( introduced virtual method Panel::doRefresh )

cego: 2.48.15 -> 2.48.19
- Fix added for CegoAdmScreen, the data file root path was not added
  to new datafiles in the 'tableset add datafile mask'
- Fixes added for CegoAdmScreen, to avoid too many admin requests,
  backup panel and data file panel are just refreshed initially and
  after add objects.
- Fix added in CegoObjectManager::alterObject, the getNewFilePage has
  been changed to type CegoObject::SYSTEM. Otherwise, a page from a
  tuple datafile is allocated, which results in strange effects
- Some adaptions for extended Screen2 interface with refresh customizing.

  with tablemanager pointer = 0.
  This is needed for cegobridge to parse procedures and generated
  other db specific code

10:49 Kurt Jaeger (pi)  Author: Björn Lemke

databases/cego: 2.48.10 -> 2.48.14

- Fix added in CegoObjectManager::alterObject, after freeing old page entry,
  page should be unfixed with marked as dirty. In the main loop,
  unfix has been changed to dirty = false
- Added function dateformat which can be feeded with two expressions
  to return a datetime value from a given format and value string (
  analog to date(x,y) which expects constant input values )
- Added more date functions to the datefunc package. Now there are
  the following date functions available
  int second(datetime d)
  int minute(datetime d)
  int hour(datetime d)
  int day(datetime d)
  int month(datetime d)
  int year(datetime d)
  datetime plusHour(datetime d, int hr)
  datetime plusDay(datetime d, int dy)
  datetime plusMonth(datetime d, int mt)
  datetime plusYear(datetime d, int yr)
  datetime minusHour(datetime d, int hr)
  datetime minusDay(datetime d, int dy)
  datetime minusMonth(datetime d, int mt)
  datetime minusYear(datetime d, int yr)
- In CegoMain, added DEFAULTDATETIMEFORMAT1 to dateFormat list to
  also parse this format for native cast from string to datetime
- Added Query Cache menu to CegoAdmScreen to manage query cache parameters

devel/lfcbase: update 1.17.2 -> 1.18.0

- Fix for some geometries in Screen::showFormBox
- Further improvements for Screen::showFormBox and showInfoBox
  ( selected rows and newline treatment )
- integrate Screen2 interface

databases/cego: update 2.48.2 -> 2.48.10

- Introduced Backup branch id for online backup verification. Due
  to datafile page id constraints, just online backups can be recovered
  inside one backup branch. Creation of a tableset and adding a
  datafile to a tableset violates this contraint, so a new backup
  branch is created.
- Added backup branch option for backup manager. So just valid
  backup files can be treated by the manager. New sample backup manager
  available in samples/chkdb
- Further improvements for cgadm screen mode. confirm dialogs added
  and backup log history indicated for online backups in case of errors
- More improvements for online backup / restore. Branch id is now
  added to archive log filename, so in case of new created or data
  file modified tablesets, the corresponding logfiles can be filtered.
  Archive logfile information for ready-for-archive and archived
  logfiles has been added to archive log information
- Fixes added in CegoClient for dump mode. Some attribute and
  attribute values have not treated correctly ( default values,
  dimension for fixed attributes, clob values )
- Fixes added for CegoClient dump and batch mode, has been tested
  with more complex acc application
- Introduced grace mode for graceful object creation. Using this
  mode, views and procedures can refer to objects, which still not
  exist. This mode might be useful for initial loads ( e.g. from a
  dump file ) to avoid dependency errors
- Fix for CegoSelect::nextTuple, _cacheSchema was not setup for
  union selects in case of empty result of the first union entry.
  This leads to an exception with cache claim leak. The claim leak
  has also been fixed by adding a cleanUp call to CegoSelect destructor
- Fix added in CegoAction::execViewCreate(), in case of grace mode,
  empty schema must be stored with created view to force recompile
  via CegoDistManager::reloadView
- Added defTabSetId parameter to several toChain methods to write
  views, procedures and triggers without explizit tableset references.
  This might be useful, if a tableset dump just references objects
  for a single tableset and it should be loaded to a tableset with a
  different name. ( e.g. select a from t1@TS1 is written as select a
  from t1, if active tableset is TS1 )
- Fixes added for alias object usage ( e.g. in combination with views )
- Added lfcbase Screen2 support to CegoAdmScreen

databases/cegobridge: update 1.6.2 -> 1.6.3

- Build fixes added

devel/lfcbase: update 1.16.6 -> 1.17.2, databases/cego: 2.47.31 -> 2.48.2

lfcbase:
- Improvements done for ncurses based Monitor class.
  Added confirm box and improved form box
- many changed have been made to Screen class ( was Monitor ).
  The changes require a recompile for consuming packages ( here : cego )
- Improvements done for Screen::showFormBox ( scrolling content in input mask )

cego:
- Fix added in CegoFactor and CegoFieldValue.
  To get the factor id for query cache management, a dedicated
  method was introduced in CegoFieldValue ( getId ) This method
  uses for DATETIME values valAsChain(true) ( to evaluate current
  timestamp in case of sysdate values ) and for all others toChain()
  ( to distinguish x = null and x = 'null' )
- Fix in CegoFunction::getId, the GETCOUNT function still was not
  treated
- Some cleanup of source file was done (removed tilde files)
- Added join optimization fix in CegoSelect::buildJoinTables.
  Inadequate predicates ( e.g. not equal compare ) are not priorized
  for table join order any more. For this the method
  CegoPredDesc::prioOnJoin has been introduced
- Grammar fix in Cego.def to ensure _returnOnFirst variable
  is set to false for non return update statements
  ( added production NoUpdateReturnOpt )
- Fix added in CegoTableManager::updateTuple,
  for the given expression list, contained subqueries must be
  retrieved and analyzed for external table references.
  Since the external count was not evaluated correctly, this led
  to a incomplete CegoSelect::getQueryId result.
  With enabled query cache, the following update did not work correct:
  UPDATE posrule pr SET artid =
    ( SELECT artid FROM article a WHERE a.artnr = pr.artnr );
- Fix added in CegoXMLSpace for user and role create routines.
  In case of already defined entities, exception was thrown
  before xml lock release
  Fix added in CegoXMLSpace::getActiveTableSet to also retrieve
  offline tablesets via includeOffline flag.
  This is needed for CegoLogThreadPool to archive occupied logfiles
  for tablesets in status offline ( for other reasons, runstate is
  set now at the beginning of the tableset stop procedure )
- many changes made in CegoAdmScreen class ( was CegoAdmMon )
  Several stabilization fixes also have been added. For database
  xml file, a unique database id has been introduced to validate
  ticket file from performed online backups ( db id must match )
- Small adaptions for cgadm screen mode window sizes
  ( corresponds to lfcbase-1.17.2 )

14:42 Kurt Jaeger (pi)  Author: Björn Lemke

databases/cego: 2.47.30 -> 2.47.31

Fix added in CegoTableManager::alterDataTable, the altering table
object has to be retrieved completely via getObject to setup
data page id and last data page id. With the new introduced
object manager method alterObject, these values
are not copied during the alter procedure.

    fcbe84c

08:53 Kurt Jaeger (pi)  Author: Björn Lemke

databases/cego: 2.47.29 -> 2.47.30

Fix in CegoObjectManager for alterTableObject.
If a new system page has to be allocated, this page was not linked.
This might lead to loss table objects for corresponding altering
queries. Furthermore, the ObjectManager has been cleaned up and
reduced in code size in such a way that generic create and alter
methods are now provided for all objects
( createObject and alterObject using encoding method inherited from
CegoDecodableObject ). This results in less code, since the create/alter
operations are just implemented once.

devel/lfcbase,databases/cego: update 1.16.5 -> 1.16.6, 2.47.27 -> 2.47.29

lfcbase:
- Added new method BigDecimal::scaleTo to change scaling for an instance.
  This includes an appropriate rounding, if scaling is reduced

cego:
- In CegoFieldValue::castTo, cast from varchar to fixed is done
  now with newly introduced BigDecimal::scaleTo method
  This includes an appropriate rounding in case of precision reduction.

devel/lfcbase: 1.16.3 -> 1.16.4, databases/cego: 2.47.24 -> 2.47.25

lfcbase:
- Fix added for BigDecimal to avoid rounding for zero trailing values,
  e.g. 119.00 / 100.00 was 1.1, should be 1.19

cego:
- Added small patch for verification check to meet new BigDecimal patch
  in lfcbase

databases/cego: update 2.47.22 -> 2.47.24

- Replaced Chain("") with Chain() for several. This was motivated by
  an observed bug for check constraint xml import, where a comparision
  between Chain() and Chain("") returned false
- Fix in CegoFunction::evalFieldValue for case REPLACE. If replace
  string is null, then empty string is replaced instead of "null"
  string.

databases/cego: upgrade 2.47.16 -> 2.47.22

- 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.

databases/cego: update 2.47.14 -> 2.47.16

- 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

19:33 Kurt Jaeger (pi)  Author: Björn Lemke

databases/cego: update 2.47.11 -> 2.47.13

- 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.

15:47 Kurt Jaeger (pi)  Author: Björn Lemke

databases/cego: 2.47.7 -> 2.47.11

- 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

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.

databases/cego: update 2.46.6 -> 2.46.7

- 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

  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.

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.

  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

  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

  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.

- 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 ...

databases/cego: update 2.45.9 -> 2.45.16

- 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

databases/cego: upgrade 2.45.8 -> 2.45.9

- Fix in CegoBTreeManager, the allowDuplicateNull flag was not
  treated any more. The duplicate handling has been moved from
  CegoBtreeNode to CegoBtreeManager

17:29 pi 

databases/cego: upgrade 2.45.6 -> 2.45.8

- 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).

devel/lfcbase: upgrade 1.14.0 -> 1.14.2
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

07:48 pi 

databases/cego: upgrade 2.45.1 -> 2.45.5

- 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

08:53 pi 

databases/cego: upgrade 2.45.0 -> 2.45.1

- 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

19:13 pi 

databases/cego: upgrade 2.44.14 -> 2.45.0

- 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

  ( more detail information about violated object )
- Code cleanup CegoTableManager, drop/create/alter operations inside
  a transaction no more allowed

05:23 pi 

databases/cego: upgrade 2.44.12 -> 2.44.13

- 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

  schema entry must be searched with Find(CegoField(Chain(),
  SYS_RB_TABLE))

databases/cego: upgrade 2.44.10 -> 2.44.11

- 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 )

15:34 pi 

databases/cego: upgrade 2.44.9 -> 2.44.10

- 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

databases/cego: upgrade 2.44.8 -> 2.44.9

- 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.

databases/cego: upgrade 2.44.7 -> 2.44.8

- 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.

databases/cego: update 2.44.6 -> 2.44.7

- 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.
