  • v1.1

    TPIE 1.1 release
    New features in TPIE 1.1:
    
    The pipelining framework makes it easier to implement efficient
    streaming algorithms. For more information about the pipelining
    framework, see doc/pipelining.dox, or read the documentation on the TPIE
    homepage.
    
    The serialization framework provides streaming primitives for working
    with item streams where items vary in size. A particular practical use
    is for streams of polygons or polygonal line segments. We use the term
    `serialization stream', because it requires that items are
    (un)serializable (rather than trivially copyable, which is the
    requirement in file_stream).
    
    If you have previously run off the TPIE master branch, notice that we
    have changed the pipelining API recently to be more internally
    consistent.
    
    Other changes since TPIE 1.0:
    
    To get the number of workers used by the TPIE job framework, use
    tpie::default_worker_count(). (65c1de4)
    
    We now support Boost filesystem version 3 (34ac4be).
    
    The array implementation has changed, removing segmented_array which
    nobody used anyway. This makes the array implementation much simpler and
    less error-prone. The TPIE array now supports custom allocators, and it
    has specialized std::copy so that an efficient memcpy implementation (or
    similar) may be used automatically. (fad27fe and 2f79196)
    
    The memory manager now has switched from a protected integer to an
    atomic primitive to keep track of used memory, speeding up non-debug
    builds. (7a4189a)
    
    The progress_indicator_arrow class no longer sends unnecessary updates
    to the standard output stream. (cc15583)
    
    The new memory manager enforcement level ENFORCE_DEBUG functions like
    ENFORCE_WARN, except that memory overusage warnings are sent to
    log_warning() rather than log_debug(). (8394479)

  • v1.0

    This marks the release of TPIE version 1.0.
    The following improvements have been merged in since 1.0rc2:
    
    * Time estimation warning has been moved to debug log. (8a9138e)
    * Priority queue memory usage slightly improved. (fa1e12e)
    * Move backtrace printed by fractional_subindicator to debug log. (f016d26)
    * Fix memory management crashes in debug mode. (91b940b)
    * Get rid of CMake option TPIE_THREADSAFE_MEMORY_MANAGEMNT. (21eb5b8)
    * Various documentation cleanup; code comments have been added/clarified.
    * Some compiler warnings have been addressed.
  • v1.0rc2

    The following bugs have been fixed since v1.0rc1.
    * Priority queue failing with a tpie::invalid_file_exception on large datasets. (0d22e10)
    * Priority queue correctness error on large datasets. (f209097)
    * tpie_name and tpie_dir_name failing rarely when the attempted temporary name was already in use. (fcc2863)
    * Memory manager warning when array::swap was used. (9496caa)
    * External queue not using the correct file::stream protocol. (0a5b9ab)
    * Several unhelpful compiler warnings inside TPIE have been muted. (f51b069)
    * Memory manager now only warns about memory overusage in exponential steps. (d98736e)
    
    Improvements:
    
    * If boost::thread reports 4 or more CPUs, use one less worker thread than the number of CPUs. (8cee7dc)
    * progress_indicator_arrow now displays breadcrumbs from fractional progress indicators. (fe47191)
  • v1.0rc1

    Release candidate 1 of TPIE 1.0
    
  • stream_speed_regression_test_point_4

    Hopefully fix default temp path under windows
    
  • stream_speed_regression_test_point_3

    Account for the extra buffer used in remove_group_buffer. This method…
    … is rarely called and the extra memory it used were not present in the memory calculations as far as I can see. This hopefully fixes a bunch of crashers that I've had with the pq, I'm currently running extensive tests.
