* [svn-r8637] Purpose:Quincey Koziol2004-06-091-37/+64
| | | | | | | | | | | | Code optimization Description: Don't allocate conversion buffer larger than the user's buffer. Platforms tested: Solaris 2.7 (arabica) FreeBSD 4.10 (sleipnir) w/parallel too minor to require h5committest
* [svn-r8631] Purpose:Quincey Koziol2004-06-091-1/+0
| | | | | | | | | | | | | | | | | Bug fix Description: Correct potential file corruption from mis-setting the metadata accumulator address. (Bugfix contributed by Sean Monner <seanm@quadrus.com>) Solution: When the new metadata overlaps with the end of the metadata accumulator and the accumulator grows in size, don't reset the address of the accumulator, since it hasn't moved. Platforms tested: FreeBSD 4.9 (sleipnir) too minor to require h5committest
* [svn-r8626] Purpose:Quincey Koziol2004-06-082-2/+39
| | | | | | | | | | | | | | | Code optimization Description: Avoid pushing errors on error stack when an object is not found in a B-tree. Sometimes we are just checking if the object exists before we insert it into the B-tree and the higher levels in the library should be responsible for determining if not finding the object in B-tree is really an error. Platforms tested: Solaris 2.7 (arabica) FreeBSD 4.10 (sleipnir) w/parallel too minor to require h5committest
* [svn-r8624] Purpose:Quincey Koziol2004-06-081-6/+17
| | | | | | | | | | | | | Code optimization Description: Use default dataset transfer property list for internal metadata I/O operations when parallel I/O is disabled. This avoids multiple copies of the properties being made when the information is not needed. Platforms tested: Solaris 2.7 (arabica) FreeBSD 4.10 (sleipnir) w/parallel)
* [svn-r8621] Snapshot version 1.6 release 2 (post5)HDF Admin2004-06-071-2/+2

* [svn-r8619] Purpose:Quincey Koziol2004-06-053-123/+176
| | | | Fix makefiles, dependencies & manifest after source file rename.
* [svn-r8617] Purpose:Quincey Koziol2004-06-054-4535/+0
| | | | | | | | Rename these files Description: Since these files contain functions that are part of the dataset information now, rename them to H5D<foo>.c
* [svn-r8614] Purpose:Quincey Koziol2004-06-0522-2309/+2220
| | | | | | | | | | | | | | | Refactor code Description: Move chunk and contiguous cached raw data from file information to dataset information. This simplifies a number of internal interfaces, aligns the code with it's purpose better and should allow more optimizations to the chunked data I/O performance. Platforms tested: Solaris 2.7 (arabica) FreeBSD 4.10 (sleipnir) h5committest
* [svn-r8607] Purpose: bug fix.Raymond Lu2004-06-031-3/+8
| | | | | | | | | Description: After an opaque datatype is created, if no tag is attached, some operations will have trouble to deal with null string of tag. Solution: Initialize opaque's tag as empty string when it's created. Platforms tested: h5committest.
* [svn-r8601] Purpose:Quincey Koziol2004-05-3118-1581/+1933
| | | | | | | | | | | | | | | | Code optimization & cleanup Description: Don't recompute the internal index value for looking up the chunk in the hash table, just use the value already computed from iterating through the chunks. Also, back-port some of the various cleanups to the source code from the development branch, to make diffing the code easier. Platforms tested: Solaris 2.7 (arabica) FreeBSD 4.9 (sleipnir) w/parallel
* [svn-r8592] Purpose:Quincey Koziol2004-05-2725-640/+882
| | | | | | | | | | | | | | | | | | | | | Code optimization & bug fix Description: When dimension information is being stored in the storage layout message on disk, it is stored as 32-bit quantities, possibly truncating the dimension information, if a dimension is greater than 32-bits in size. Solution: Fix the storage layout message problem by revising file format to not store dimension information, since it is already available in the dataspace. Also revise the storage layout data structures to be more compartmentalized for the information for contiguous, chunked and compact storage. Platforms tested: FreeBSD 4.9 (sleipnir) w/parallel Solaris 2.7 (arabica) h5committest

* [svn-r8564] Purpose:Albert Cheng2004-05-211-3/+93
| | | | | | | | | | | | | | Improvement Description: Break up the C99 integer types detection into even smaller sub-module routines. This has dropped the compile time (with optimization) from 94 seconds to 6 seconds. Platforms tested: h5committested. Misc. update:
* [svn-r8561] Purpose:Quincey Koziol2004-05-211-0/+2
| | | | | | | | | | | | Bug fix Description: Add prototypes for H5S_select_serial_size() and H5S_select_serialize() that were causing the library to fail when built with C++ compiler. Platforms tested: FreeBSD 4.9 (sleipnir) w/CC=g++ Only affects C++ builds, so no h5committest
* [svn-r8557] Purpose:Albert Cheng2004-05-201-3/+3
| | | | | | | | | | | Code cleanup Description: Changed local variables declaration to static to please compilers. Platforms tested: Tested by generating H5Tinit.c and verified it was same as before. Tested in TG_NCSA.
* [svn-r8549] Purpose:Albert Cheng2004-05-201-39/+157
| | | | | | | | | | | | | Improvement. Description: Some compilers, e.g., Intel C v7.0, took a long time to compile with optimization when a module routine contains many code lines. Divide up all those types detections macros into subroutines, both to avoid the compiler optimization error and cleaner codes. Platforms tested: h5committested.
* [svn-r8547] Purpose:Albert Cheng2004-05-201-14/+1
| | | | | | | | | | Bug fix. Backed out the byte order detection code. It was not compatible with v1.6. Platforms tested: Tested in TG_NCSA. Misc. update:
* [svn-r8546] Purpose:Albert Cheng2004-05-201-1/+14
| | | | | | | | | | Folded byte order detection from v1.7 to this. Platforms tested: No test because it has been tested in v1.7. Will be tested in changes to be committed immediately. Misc. update:
* [svn-r8543] Purpose:Quincey Koziol2004-05-2013-262/+511

| | | | | | | | | | | | Code optimization Description: Defer creating the span trees for hyperslab selections until they are actually needed (which may be never, in certain circumstances). Platforms tested: Solaris 2.7 (arabica) FreeBSD 4.9 (sleipnir) w/parallel
* [svn-r8506] Purpose:Quincey Koziol2004-05-122-19/+25
| | | | | | | | | | | | | | | | | Code optimization Description: Eliminate many redundant lookups to check for no-op type conversion by remembering that a type conversion path is the no-op path. Also, don't allow non-no-op conversions which happen to be no-ops on a particular machine (such as int<->long conversions on machines where int and long are the same size and format, etc.) to replace the default no-op conversion. Platforms tested: Solaris 2.7 (arabica) FreeBSD 4.9 (sleipnir) w/parallel

* [svn-r8459] Purpose:Quincey Koziol2004-05-018-105/+101
| | | | | | | | | | | | | | | Code optimization Description: Move the element size for the selection into the selection iterator instead of always passing it as a parameter. Also, eleminate another 64-bit multiply for "all" selections. Platforms tested: Solaris 2.7 (arabica) FreeBSD 4.9 (sleipnir) too minor to require h5committest
* [svn-r8458] Purpose:Quincey Koziol2004-05-015-256/+176
| | | | | | | | | | | | | Code optimization Description: Stop straddling the line and always use elements instead of bytes to determine how how I/O to perform on a selection. Platforms tested: Solaris 2.7 (arabica) FreeBSD 4.9 (sleipnir) too minor to require h5committest
* [svn-r8455] Purpose:Quincey Koziol2004-05-014-35/+11
