v4.5.1

Enhancements (C API)

• Updated driver information set by OCILIB since v3.1.0 (column CLIENT_DRIVER in V$SESSION_CONNECT_INFO)
  • it is now including OCILIB version (e.g. "OCILIB : x.y.z" instead of "OCILIB")
• Extended OCI_SeTrace() and OCI_GetTrace():
  • Added OCI_TRC_OPERATION: Name of the database operation set by the client application to be monitored (according Oracle docs)
  • This value is stored the database in the column DBOP_NAME of the system view V$SQLMONITOR
  • OCI_GetTrace() returns now NULL instead of an empty string if the given trace is not set or nullified
• Release Windows binaries are now built using VS 2017 15.5.6 (instead of VS2017 15.3.2)

Fixes (C API)

• Driver information (introduced in Oracle 11gR1: was set by OCILIB if
  • Oracle version >= 11gR1 for standalone connections and connections retrieved from connection pools
  • Oracle version >= 11gR2 for connections retrieved from session pools
  • Now it sets it correctly in all cases when Oracle version >= 11gR1
• Issue #141: OCIBindRaw() now accepts empty buffers (non null data with size = 0)
• Issue #142: OCI_GetStruct() was filling numeric fields with garbage values since v4.5.0
• Issue #143: OCI_SetTrace(): passing NULL values for clearing trace information leads to segfaults
• Issue #144: OCI_SetTrace(); If called at least once, it was causing small memory leak in OCI_ConnectionFree()
• Issue #145: Using OCI_BAM_INTERNAL for types using handles was leading to segfault when executing the statement
  • Impacted types:OCI_Object, OCI_Lob, OCI_File, OCI_Timestamp, OCI_Interval, OCI_Ref and OCI_Collection

Fixes (C++ API)

• Issue #141: ocilib::Statement::Bind<ocilib::Raw, unsigned int>() accepts now empty ocilib::Raw

Miscellaneous

• OCILIB requires now C99 to be activated for compiling:
  • When using autotools (Unixes): Enforcing C99 compiler flags using AC_PROG_CC_STDC() macro
  • When using Visual Studio: OCILIB cannot be compiled anymore with VS2010 and earlier versions (released binaries use VS 2017)
  • This was motivated for using variadic macros and allow variable declarations not only at beginning of blocks
• Addressed static code analysis hints and warnings
• Internal code refactoring and factorization
• Reduced cyclomatic complexity of some internal functions
  • Some methods (connection logon/logoff, bindings) were far too long and had been decomposed and split in smaller ones

  • Added CollationID enumeration
  • Extended StatementType enumeration: added TypeMerge
  • Extended SessionFlags values: Added SessionSysAsm, SessionSysBkp SessionSysDgD, SessionSysKmt, SessionSysRac, SessionPreAuth

v4.4.0

Enhancements (C API)

  • if an OCI_Object instance real type is a sub type of its column object type, OCILIB is dynamically retrieving its real and right type instead of processing it as its base type
  • Added missing synchronized access when iterating the list of existing OCI_TypeInfo in OCI_TypeInfoGet()
• Allocation Binding mode updates
  • Added BindGetAllocationMode()
  • updated OCI_GetBindAllocation() and OCI_SetBindAllocation() documentation to properly specify their usage

Fixes (C API)

• Issue #81: Fixed OCI_GetInt() on string columns
  • Wrong implicit string to integer conversion (returning 0 whatever string value) occurred under following conditions:
    • Column is string based
    • Oracle client < 12gR1
    • Using OCI_GetInt() or OCI_GetUnsignedInt()
• Issue #86: Fixed wrong error information when statement execution failed involving 64bit integer binds
  • It occurred under following conditions:
    • Binding 64bit integer host variables with OCI_BDM_OUT flag set (default if OCI_BindSetDirection() has not been called)
    • Statement execution failed on the server for any reasons (server side error, constraint violation, ..)
  • Real server side error information was not reported by OCI_GetLastError() or error callback
  • Instead an error "OCI-22060: argument [2] is an invalid or uninitialized number" was reported
• Issue #88: Fixed OCI_GetString() on BLOB columns with blob size > 1024 bytes
  • Filling the resulting string with BLOB data led to a buffer overflow
• Issue #89: Fixed Segfault occurring in OCI_Execute()
  • The issue was a wrong offset computation when trying to update user strings after execution.
  • It occurred under following conditions:
    • OCI_CHARSET_WIDE (Unicode) ocilib build
    • Unix/Linux (wchar_t implemented as 32bit integers)
    • Binding host string variable with OCI_BDM_OUT flag set (default if OCI_BindSetDirection() has not been called)
