databases/cegobridge: update 1.3.0 -> 1.4.0
cego:
- Fix in CegoTableManager::updateTuple, while setting up expression
list, field list array must be setup BEFORE block ist set, since
field list is needed by block setup ( in case of subqueries for
prepare )
cegobridge:
- Adaptions for cego-2.39
Submitted by: Bjoern Lemke <lemke@lemke-it.com>
databases/cegobridge: update 1.2.1 -> 1.3.0
cego:
- Fix in CegoSelect::clone, pUnionSelect was not cloned, which might
lead to seg faults
- Introduced predicate clause for select .. in ( expr, expr, ... ),
e.g. select * from t1 where a in ( 1, 2, 3 ); This was still not
implemented but is part of standard SQL.
cegobridge:
- Adaptions made for modified cego-2.38.0 API with extended
CegoDatabaseFormatter::formatPred method ( exprList was added for
new introduced select in ( expr list ) predicate )
Submitted by: Bjoern Lemke <lemke@lemke-it.com>
databases/cego: update 2.36.4 -> 2.37.0
databases/p5-DBD-cego: update 1.3.0 -> 1.4.0
databases/cegobridge: update 1.1.6 -> 1.2.0
lfcbase:
- Layout improvements in Pager class
- Changed constructor for Net and NetHandler class to setup maxSendLen.
Since this changes the API, minor release level has been increased
cego:
- Improvements for cgblow simulation mode added
- Improvements for cgclt, added pipe mode to read input from stdin
Now comments are allowed also after delimiter token, e.g.
create table t1(a int); -- a sample table
- Support for lfcbase-1.11.x with new Net API.
The parameter maxSendLen ist still a constant in CegoDefs.h
Improvements added for CegoXMLSpace::setPerm, for existing permissions,
just tableset, filter or right can be set up now,
e.g set permission p1 with right=WRITE for role1 just sets the right
value for permission p1 to value WRITE, all other values are unchanged
- Added show parameter admin command to show all tableset independent
database parameters
p5-DBD-cego:
- support changed API with lfcbase-1.11.0
cegobridge:
- support changed API with lfcbase-1.11.0

databases/cego: update 2.36.3 -> 2.36.4
databases/cegobridge: update 1.1.5 -> 1.1.6
cego:
- Fix in CegoSelect::nextTuple, before adding an entry to the query
cache, it has to be checked, if any tables from foreign tableset
are referenced in the query. If so, no cache entry is made, since
table changes for foreign tables are not detected.
- Improved error messages for invalid database objects
- Decreased shutdown delay time by reducing net delays for all
thread pools and optimized mediator thread wait procedure
- Completely removed the nologging option for import actions.
Logging is disabled in any case now.
- Optimization added for log handling. During ( xml ) import,
logging is completely deactivated, after import is completed,
log is started again and a checkpoint is written.
Since import can be repeated in case of a system during import,
nothing gets lost. Deactivating logging increases import speed and
avoids side effects
cegobridge:
- Speed up imports by changing the way the parser reads the input
Submitted by: Bjoern Lemke <lemke@lemke-it.com>
databases/cego: update 2.32.8 -> 2.32.11
databases/cegobridge: update 1.1.2 -> 1.1.3, fix build with clang 4.0
devel/lfcbase:
- Added Monitor class for ncurses based GUI utility implementation.
This class provides GUI layout and event handling to simply ncurses
based GUI tool implementaton.
- Added class Pager for curses based pager implementation
databases/cego:
- Include stdlib.h added in CegoNet ( still missing forLinux compiles )
- Added CegoFieldValue::getDim method required for arithmetic operations
on fixed values
- Fix in CegoTableManager::getPoolInfo, readdelay and writedelay was
not calculated correctly
- Fix in CegoDistManager::stopDistTableSet, removing of btree objects
from database object dictionary was still missing
- In CegoTableManager::dropTableSet now also counter objects are
dropped ( stored in the database xml file ).
- Added some sizing optimizations for CegoAdmMon forms
- Fix in CegoRecoveryManager::recoverCurrentTransactionLog, added
the force option to addCounter method, since counters already could
be synched to xml ( not completely transaction save )
- Online index build up tested and verified. First tests with heavy
insert operations ( using cgblow ) during index build went succesful.
- Improvements for CegoAdmMon role permission handling, added remove
permission option
- Preparation of CegoObjectCursor and CegoTableManager to support
online index rebuild with write access to the table.
For this, concurrent insert operations have to be performed with
append =true. The ObjectCursor locks the last page until the index
rebuild is finished ( method setLastPageSync )
In this way, the index can be build up in parallel, while further
tuples could be appended to the table. ( just supported for btree
index objects )

databases/cego: 2.28.3 -> 2.29.1
databases/cegobridge: 1.1.1 -> 1.1.2
Please note: Updating cego databases needs an export/import
cycle for 2.28 -> 2.29
lfcbase:
- Fix in Datetime.cc, added include config.h, otherwiese the local
implementation of strptime ist used. This should just be done, if
the system API does not provide this call ( e.g. MINGW ) .
- Memory leak fixed in File::readLine
cego:
- Started with clob datatype implementation
- Fix in CegoSelect constructor, _cacheEnabled var was not initialized
in the decoding constructor, which might lead to core dumps in case
of recovery of complex with enabled querycache Fix in CegoAdminThread
constructor, disableAuth method for TableManger called, otherwise
tableset recovery might fail with auth error
- Required network protocol expansions done for clob handling
(putclob, getclob, delclob)
- More work on clob handling. A fix was done for update operations
on clob values in CegoTableManager::updateTuple method. Before
updating the tuple, all clob references must be cloned, otherwise
in case of untouched clobs, references are invalid. This approach
is brute force, better would be, to stay on the untouched clob
references. But in terms of transaction and recovery handling,
this is not trivial
- Very long strings are handled now in CegoAction and CegoClient
to also parse large clob values
- Modification in cgclt for raw mode, Now just plain data is listed,
with the command line option --raw=X, a separator token can be setup
as a column separator
cegobridge:
- fix build problem
Submitted by: Bjoern Lemke <lemke@lemke-it.com>
devel/lfcxml: 1.1.8 -> 1.2.2
databases/cego: 2.27.2 -> 2.28.3
databases/p5-DBD-cego: bump portrevision
databases/cegobridge: bump portrevision
IMPORTANT: Upgrades of cego 2.27.x to 2.28.x databases has to be done by
export and import.
lfcbase:
- Adaptions made for build with msys2 / mingw64. Many windows
specific stuff could be eliminated, since mingw64 provides better
POSIX support ( e.g. pthreads, timer functions .. )
lfcxml:
- Fix in configure.ac to find lfcbase and for FreeBSD
cego:
- Fix in CegoSelect::CegoSelect, the pCacheList variable was not
initialized to 0 for all constructors. In case of system table
selects, the variable might be undefined which might lead to
segmetation faults.
- Changed synchronization level for btree creation. So the base
table can also be accessed while btree is created ( During creation
btree status is invalid )
This also allows to perform on online btree reorganization, since
a new btree can be build up in parallel
- Fix in CegoSystemObject::createSystemSpace, id values for bustat
table must start with id 1 instead of id 0, otherwise, bustat
information retrievel fails or may result in a core dump
( select * from $bustat )
- Added performance fix for CegoQueryHelper::decodeFVL, since the
tuple context information is already from the method called, the
tid, tastep and ts parameters have been remove from this method.
This saves some decoding time
- Please note, that version 2.28.x makes datafiles from older versions
incompatible.
An upgrade requires a xml tableset export of existing data and a
restore after succesful upgrade
- 2.28.x also contains many code cleanup fixes and some fixes for
btree handling.
- Fix in CegoTableManager::createBTree, in case of an exception
during build up, the allocated have to be cleanup up. For this the
a rollback method was introduced in class CegoBTreeManager.
Fix in CegoTableCursor, invalid btree objects have not been ignored
- Many adapations to make cego full 64bit ready also in combination
with MSYS2 / MINGW64. This resulted in change of many variables
from type long to type unsigned long long (type long is just 32 bit
for Windows ) With an appropriate MSYS2 / MINGW64 installation,
cego compiles proper and runs stable now.
Many thanks to the MSYS/MINGW developers for their amazing work !
- Several changes from type int to type unsigned long long
- Fix in CegoTableManager::deleteDataTable ( renamed to
deleteDataTableEntry )
Since we allow now parallel updates, the method must check if the
target tuple has already been touched by another transaction.
Otherwise, invalid double entries could occur in case of concurrent
updates on the same tuple.
If a concurrent transaction is detected, the method returns false.
This return value is used by the updateTuple method to decide,
if the subsequent insert operation must be performed.
- Since it is not enough jut checking the tuple header info for
update deletes, a record locking has to be added to avoid duplicates.
In this sense, record locking for setTupleInfo method call ( used
in CegoTableManager and CegoTransactionManager ) was added. For
this, the lockRecord and unlockRecord method have been reactivated
in CegoLockManager class.
This lock avoids, that in case of concurrent tuple updates duplicate
tuples are produced by an update.
- Fix in configure.ac to find lfcbase and lfcxml and for FreeBSD
