Bug fixes
Description:
This checkin addresses two separate bugs:
#1 - When a compound datatype with a VL datatype as a field is used
to read or write data, the datatype conversion paths added to
the table of paths were treating the VL datatypes somewhat too
genericly - they weren't dicriminating between VL datatypes used
in different files and therefore there was the possibility that
a path in the table having information for one file could get used
with a second file, causing errors or core dumps (if the first
file was closed before the later file used the path).
#2 - When composite (compound, array or VL) datatype paths in the datatype
conversion table are being tested to see if they can be used for
the current datatypes being converted, they can cause additional
conversion paths to be registered in the conversion path table.
Since this causes the global table to change size and entries to
move around, it is possible that the local variables tracking a
potential path could become incorrect as the global table was
changed out from underneath them.
Both bugs fixed are described in bug #703
Solution:
Two separate fixes:
#1 - Changed H5T_cmp to differentiate between VL datatypes in different
files and not to return datatypes in two different files as equal.
#2 - Note size of global table before evaluating datatype paths. Then,
after the appropriate path has been chosen, check if the size of
the global table has changed and recompute the position of the path
chosen in the table if necessary.
Platforms tested:
FreeBSD 4.5 (sleipnir)

HDF5 version 1.5.20 currently under development
Please refer to the INSTALL file for installation instructions.
------------------------------------------------------------------------------
This release is almost fully functional for the entire API defined in the
documentation, see the RELEASE.txt file in this directory for information
specific to this release of the library. The INSTALL file contains
instructions on compiling and installing the library. The INSTALL_parallel
file contains instructions on installing the parallel version of the
library.
Documentation for this release is in the html directory. Start with the
"index.html" in that dictectory.
Four mailing lists are currently set up for use with the HDF5
library.
hdf5 - For general discussion of the HDF5 library with
other users.
hdf5dev - For discussion of the HDF5 library development
with developers and other interested parties.
hdf5announce - For announcements of HDF5 related developments,
not a discussion list.
hdf5cvs - For checkin notices of code development on the library,
not a discussion list.
To subscribe to a list, send mail to "majordomo@ncsa.uiuc.edu",
with "subscribe <list>" in the _body_, not the Subject, of the message.
E.g., subscribe hdf5
Messages to be sent to the list should be sent to "<list>@ncsa.uiuc.edu".
Nearly daily code snapshots are now being provided at the following URL:
ftp://hdf.ncsa.uiuc.edu/pub/outgoing/hdf5/snapshots
Please read the readme file in that directory before working with a library
snapshot.
The HDF5 website is located at http://hdf.ncsa.uiuc.edu/HDF5/
Bugs should be reported to hdfhelp@ncsa.uiuc.edu.
