Changelog

master

v4.1.16

v4.1.15

  • Add (Un)Marshal{Text,JSON} to OCINum, for nicer marshaling to JSON.

v4.1.14

  • Allow specifying FetchLen and LOBFetchLen.
  • Add Rset.ColumnIndex helper function.

v4.1.13

  • Fix bindStirngSlice error of nullInds reuse without reset.

v4.1.12

  • Do not free ocistmt - panics (issue #222).

v4.1.11

  • Return ErrBadConn from ExecContext, QueryContext if the culprit is bad conn. Fixes #205.

v4.1.10

  • Fix missing OCI handle frees on error (issue #207).

v4.1.9

  • Fix context deadline issue 192.

v4.1.7

  • Fix missing Rset.Close in DrvQueryResult.Next.

v4.1.6

  • Fix memory consumption in defString.

v4.1.5

  • Allow Num, OraNum and OCINum as bind parameters.
  • Allow DRCP (Database Resident Connection Pooling).
  • Fix reconnection when disconnected from Oracle (return driver.ErrBadConn).
  • Fix LOB reading error happening only spuriously, under pressure - issue 159.

v4.1.4

  • Fix LOB reading (issue #159).
  • Remove ociErrorNL as it does locking, against its name and comment.
  • Remove all remaining ora.v3 traces.

v4.1.3

  • Open LOBs for reading only at the first read - this eliminates the error ORA-24804 when the Row contains more than one LOB.

v4.1.2

  • Fix LOB reading with ora.S by simplifying reading code and using AL32UTF8 explicitly.

v4.0.1

  • Add an ora.L type to specify ora.Lob as column type in Qry and Prep.

v4.0.0

  • Rewrite the tests to run parallel
  • Rewrite the tests to use subtests
  • Add RWMutex everywhere where needed to be -race-free
  • Change the configuration to use immutable structures (StmtCfg and RsetCfg). This means cfg.Set... methods returns a copy, does not change the original - you have to call drv/env/srv/ses/stmt/rset.SetCfg(cfg)!
  • Remove pooling from Con - that's already done in database/sql.
  • Allow setting column type to S for numeric columns (with ora.SetCfg(ora.Cfg().SetNumberFloat(ora.S))), too. This enables us you to .Scan into a *string.
  • Add Stmt.Parse for only parsing the query.
  • Fix open/close memory leak by adding more handle freeing - see #148.

v3.8.0

  • go1.8: support additional features, as requested by @kardianos in #127.
  • Change default column types for BLOB and CLOB: Bin and S, instead of D and D. With this change the driver will return a string/[]byte from [CB]LOB columns, instead of an io.ReadCloser.
  • Return driver.ErrBadConn for connection errors, to allow database/sql to reconnect.

v3.7.4

  • Add RTrimChar to StmtCfg, default true. This makes the strip of right padding of CHAR columns configurable.

v3.7.3

  • Fix a panic with Con.sysName.
  • Be more forgiving for empty/non-open/NULL result sets returned by Oracle.
  • Treat SQLT_INT columns returned by TimesTen just as SQLT_NUM.
  • Make *[]string, *[]{,u}int{16,32,64} and *[]{Ui,I}nt{16,32,64}, *[]Date bindable.
  • Use a bytesArena (sync.Pool-based []byte arena) for []byte allocations.

v3.7.2

  • Fix panic in Pool.Get - #118.
  • Make returned LOB colums obey the given GoColumnType, to be able to force the into string/[]byte - see #117.
  • Return nil for everywhere in def*.value, if possible (string is an exception, see #105, #106).

v3.7.1

  • Fix defDate NULL handling error resulting in reading garbage as Time.
  • Add Ses.SetAction to be able to set the session's Module and Action attributes.

v3.7.0

  • Add "C" field to Lob to allow setting bind parameters to CLOB (default is BLOB).
  • Add date.Date, an implementation for encode/decode Oracle 7 byte DATE format, to avoid the overhead of calling C.OCIDateTime... functions. And use it in Rsets.
  • Make ora.Date use date.Date.
  • Fix nested rsets (rset with rset as field).
  • Add a new Pool implementation, which has a simple 1-1 pairing between ses and srv - easier to use, and "automatically" correct for parallel execution.
  • get rid of NewSesCfg() and NewSrvCfg()

v3.6

  • Refactor def* (resultset columns) to be more common, and allow multiple row fetch.
  • Use multiple row fetch to speed SELECTs - closes issue #86.

v3.5

  • Modify default for CHAR(1) columns: use ora.S (string), NOT ora.B (bool).
  • Add connect " AS SYSDBA" functionality.

v3.4

  • Implement PL/SQL TABLE support to be able to call PL/SQL blocks/stored procedures with slices of simple types.
  • Add numberBigInt and numberBigFloat colum types. This allows tweaking the used column types for NUMBER columns with unknown scale/precision.
  • OCINum instead of OraNum - space saving and less C calls (implemented pure Go read/write of Oracle OCINumber, in num directory).

v3.3

  • Introduce new Num and OraNum data types and N Go Column Type to represent Oracle numbers fully, by exchanging them with Go as strings. Make N the default column type for numbers unrepresentable by int64 or float64 (more digits than 19 or 15).

v3.2

  • Rewrite for Go 1.6 cgo restrictions.

v3.1

  • Use the returned length info for several places when reading attributes - such as column names.
  • Use float64 for non-integer numeric column types.

v3.0

  • Big rewrite of handles to pool them properly.
