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