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

devel/lfcbase,databases/cego: update 1.18.3 -> 1.18.5, 2.48.19 -> 2.48.23
lfcbase:
- Added scrollable feature to Screen2::Message, so longer messages can
now be handled by the panel
- improvements for Screen2:Message panel
cego:
- Added default append mode setting for tableset.
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.

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

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 (Only the first 15 lines of the commit message are shown above )

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() (Only the first 15 lines of the commit message are shown above )

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.

[ 08:53 Kurt Jaeger (pi) Author: Björn Lemke ] 35129a4
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.

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

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.

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.

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

- 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.

not extraced correctly
Example:

insert into t1 values ( 1, 'alpha');
create btree b1 on t1(b,a); -- inverted, value for a would be
not setup correctly

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).

for File::flush implemention, darwin rather requires a fcntl call
with option F_FULLFSYNC instead of fsync ( see OSX man page for
fsync )

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

databases/cego: update 2.39.12 -> 2.39.13
- Introduced CegoTransactionManager::getCrashAffectedTables method.
In case of a crash recovery, all transaction affected tables have
to be analysed for index objects. Before finishing transactions,
the index objects have to be invalidated ( since they might be
corrupted ) and after completion of transactions they have to be
recreated. This is done now in CegoTableManager::finishOpenTransaction
- Fixes in CegoLogManager, CegoRecoveryManager, CegoDistManager and
CegoTableManager for LSN handling. Instead of saving the next LSN,
now the current written LSN is recorded in CegoLogManager. This
seems to be more natural, since a lot of methods set up the LSN to
a value + 1. Also this fixes a mismatch between commited lsn and
current lsn, which leads to a tableset recovery during startup in
any case ( occured with version 2.39.9 )

databases/cego: update 2.39.11 -> 2.39.12
- Patch in CegoClient to catch format exceptions like
"Invalid datetime string <0> for format <%d.%m.%Y %H:%M:%S>"
This may happen, if on server side bad union selects are defined like
create view v1 as
select a as a, b as b from t1
union all
select a as a, 0 as b from t2;
where b is a datetime data type. In this case, invalid formatted
strings occur on the client side, which are catched now.
- Patch in CegoDatabaseManager::useObject to support lock
delay values > 1 sec. The DBM_LOCKDELAY value in CegoDefs has now
increased to 2500 msec. In some cases for heavy updates
( e.g. clob updates ) this might be useful to avoid ugly exclusive
lock delay messages in database log file
- Fix in CegoTableManager::updateTuple. If the update fails ( this
might happen, if another transaction actually updates the corresponding
tuple ), any allocated lob values are freed now. Otherwise the
data pages for the lob values were allocated with no more references.

databases/cego: update 2.39.9 -> 2.39.11
- Improvements for log handling, the logIt method was moved from
CegoTableManager to CegoBufferPool. This allows a more adequate
locking of the logging actions. For this the tsLock array has been
removed from CegoTableManager and lmLock array has been set up in
CegoBufferPool. Since checkpoint writing occurs in CegoBufferPool
( which is also relevant for loging operations ), the logging method
is now part of CegoBufferPool.
- The logAction method in CegoLogManager has also been improved in
a way, that a log buffer is not allocated for each logging operation
anymore. Instead, a logBuf array has been defined for all tablesets
and the logBuf is reallocated, if the current logging record exceeds
the log buffer.

CegoLogManager::nextLSN method has been introduced. Now it is no
more ensured that the log is written with increasing LSN, so some

- Added dbcheck/check072.sql. This implements the calculation of
fibonacci numbers using stored procedures as a demonstration for
massive recursive procedure calls
- Optimization for procedure load in CegoFunction::evalFieldValue
( case USERDEFINED ), procedure is just loaded as a dedicated
instance ( via loadProcedure method ), if pMasterBlock is set. This
avoids ( expensive ) dedicated load, if the procedure is still not
in use by the corresponding thread. So just for recursive procedure
calls, the dedicated load happens.

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 (Only the first 15 lines of the commit message are shown above )

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 2.36.1 -> 2.36.2
- Fix in CegoFactor::setFieldListArray, the _flaCached variable has
to be set to false, if _pFLA is set to a different value. Otherwise,
we might refer to invalid memory, which results in core dump

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

the corresponding tableset must be set to zero, otherwise in case of crash
recovery procedures a transaction id might be active and the open
transactions are not completed correctly
