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

--[ Redis 3.0.5 ] Release date: 15 Oct 2015
Upgrade urgency: MODERATE, the most important thing is a fix in the replication
code that may make the slave hanging forever if the master
remains with an open socket even if it is no longer able to
reply.
* [FIX] MOVE now moves the TTL as well. A bug lasting forever... finally
fixed thanks to Andy Grunwald that reported it.
(reported by Andy Grunwald, fixed by Salvatore Sanfilippo)
* [FIX] Fix a false positive in HSTRLEN test.
* [FIX] Fix a bug in redis-cli --pipe mode that was not able to read back
replies from the server incrementally. Now a mass import will use
a lot less memory, and you can use --pipe to do incremental streaming.
(reported by Twitter user @fsaintjacques, fixed by Salvatore
Sanfilippo)
* [FIX] Slave detection of master timeout. (fixed by Kevin McGehee, refactoring
and regression test by Salvatore Sanfilippo)
* [NEW] Cluster: redis-trib fix can fix an additional case for opens lots.
(Salvatore Sanfilippo)
* [NEW] Cluster: redis-trib import support for --copy and --replace options
(David Thomson)
</ChangeLog>
- Support multiple values in *_OLD_CMD, i.e. we can now fix both "/usr/bin/python" and "/usr/bin/env python" at the same time
- Default *_OLD_CMD values are now always appended, so you don't need to specify them in individual ports
- Add lua support (depends on USES=lua)
- Add more default values, such as "/usr/bin/env foo" for python, perl, bash, ruby and lua
- Shebangfix now matches whole words, e.g. we will no longer (erroneously) replace "/usr/bin/perl5.005" with "${perl_CMD}5.005" (but "/usr/bin/perl -tt" is still (correctly) replaced with "${perl_CMD} -tt")
Note that *_OLD_CMD items containing spaces must now be quoted (e.g. perl_OLD_CMD=/bin/perl /usr/bin/perl "/usr/bin/env perl")
Update shebangfix usage according to new rules in many ports:
- Remove *_OLD_CMD for patterns now replaced by default
- Quote custom *_OLD_CMD which contain spaces
Fix shebangfix usage in many ports (irrelevant to infrastructure change):
- Remove redundant SHEBANG_LANG (no need to duplicate default langs)
- Remove redundant *_CMD (such as python_CMD=${LOCALBASE}/bin/python${PYTHON_VER} when USES=python is present)
- Never use *_OLD_CMD in REINPLACE_CMD matchers, these should always look for exact string
