Jack Christensen 0f7bf19387 Add *Conn.SetLogLevel 
Allow changing log level after connection is established. Because
log level and loggers can be set independently, it is now possible
to have a log level above none when there is a nil logger. This
means all log statements need to check for nil logger and an
appropriate log level. This check has been factored out into
*Conn.shouldLog.
 2016-02-13 10:13:10 -06:00
Jack Christensen cffae7ff5d Add SetLogger to *Conn 
Allow replacing logger after connection is established. Also
refactor internals of logging such that there is a log method that
adds the pid to all log calls instead of making a new logger object.
The reason for this is so pid will be logged regardless of whether
loggers are replaced and restored.

 2014-12-19 08:25:33 -06:00
Karl Seguin a8f5ce12c5 Trying to reduce memory allocation. logQueryArgs is called even when 
using the default discardLogger. This allocates quite a bit of memory.
Created a default dlogger instance and avoid logging code when that's our
logger. I couldn't think of a better implementation without touching the
Logger interface.

On 100 000 inserts, this brought the allocation down to 58MB from 122MB.
It should also result in some small performance gains.

Andy Walker 821605a8dd Adding hstore support. map[string]string will encode to hstores and throw errors on hstores with NULL values, and there is now a NullHstore type that is basically map[string]NullString and will both accept and decode NULL values properly 2014-09-19 15:27:15 -05:00
Brian Dunn and Jack Christensen a68115fc03 Fix data race with Rows and ConnPool 
In an effort to reduce memory allocations, Rows was stored on the
Conn. This caused a race condition where Rows are closed and this
returns the Conn to the Pool. The Pool could then give out the Conn
again. Rows would then be reanimated and the original Rows could reclose
it.

Jack Christensen 61bf7d841a Always use bound parameters 
PostgreSQL has two string syntaxes, one that allows backslash escapes and one
that does not (SQL standard conforming strings). By default PostgreSQL uses
standard conforming strings. QuoteString was only designed for use with
standard conforming strings. If PostgreSQL was configured with certain
combinations of the standard_conforming_strings and backslash_quote settings,
QuoteString may not correctly sanitize strings. QuoteString was only used in
unprepared queries, bound parameters are used for prepared queries.

This commit alters pgx to use always use bound parameters.

As a consequence of never doing string interpolation there is no need to have
separate Text and Binary encoders. There is now only the Encoder interface.

This change had a negative effect on the performance of simple unprepared
queries, but prepared statements should already be used for performance.

fixes #26
