4b9d046c6e Fully resolve potentially ambiguous symbols by removing using namespace statements from headers which have a cascading effect. This causes potential behavior changes when switching to c++11 since symbols can be exported from std and boost while both have been imported into the global namespace. 2019-04-29 01:21:15 -05:00

9363504dd4 MCOL-1847. Addressed feedback from Daniel. 
Instead of a seperate param for cache size, we decided
to allow an override of the NumBlocksPct param instead.
If NumBlocksPct ends in an 'm' or a 'g', it will be interpreted
as megabytes or gigabytes instead of a %age.

24c5e93756 MCOL-1737 Add debug logging options for LRU cache 
This adds options which are user enabled to debug the LRU cache inside
ColumnStore. Specifically cache flushing.

It adds the following:
* PrimProc flush information when SIGUSR2 mode is enabled
* cpimport dictionary flush information when -d2 is used
* WriteEngineServer DML flush information to STDERR

4f6949835d MCOL-1037 Fix race condition in FIFO buffer 
The FIFO buffer could get data in next() whilst a data swap is happening
due to a rare race condition. This patch adds mutexes around the parts
that could race.

The observed effect of this race was during a complex aggregate query
the results would occasionally be incorrect.

In addition this fixes a race condition in PrimProc's regex processor.

40405c792a MCOL-1474 Add error handling to PTP 
PriorityThreadPool didn't have very good error handling. If something
failed it would just ignore whatever was being processed. This could
lead to a query continuing without retreiving all of the required data.

This patch adds error handling, sending a message back to the client
and a log message. It also destroys and recreates the pool thread.

fa3574b6b1 MCOL-1246 Make matching SQL-92 compliant(ish) 
SQL-92 basically specifies for a NOPAD collation that only space should
be ignored for matches. Tabs and other whitespace are handled
differently. We don't fully support collations yet so we assume the
defaults.

905ce2ce8b MCOL-1246 Fix for non-DSS step 
For TEXT columns (and some other scenarios) we don't do a DSS step to
scan dictionaries and do it directly in the BPS step instead. This patch
applies the previous fix to this case too.

17e954db7d MCOL-1246 Fix string matching for whitespace 
For equality string matches other engines ignore trailing whitespace
(this does not apply to LIKE matches). So we should do the same. This
patch trims whitespace for MIN/MAX extent elimination checks, fixed
width columns and dictionary columns during equality matches against
constants (SELECT * FROM t1 WHERE b = 'ABC').
