[svn-r5859] ./hdf5-devel/release_docs/RELEASE.txt

Browse Source 
Purpose:
    Merged from 1.4 branch
Description:
    API tracing improvements
Platforms tested:
    Linux (--disable-hsizet didn't work before my changes and still doesn't
    work, but --enable-hsizet is fine).



Note: This checkin includes temporary code in H5FDmpiposix.c to turn
off GPFS byte range token prefetches on ASCI/Blue.  Once the HDF5 API
supports the necessary prerequisite functionality this temporary code
can be migraged up above HDF5.

* API tracing has been improved. Nested API calls don't screw up the
output format; function call and return event times can be logged;
total time spent in each function can be logged. The following
HDF5_DEBUG environment variable words affect tracing:
trace -- turn on/off basic tracing
ttimes -- turn on tracing and report event times and
time spent in each API function.
ttop -- turn on tracing but display only top-level
API calls.
