| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Bring "shape same" changes from LBL branch to trunk. These changes allow shapes that are the same, but projected into dataspaces with different ranks to be detected correctly, and also contains code to project a dataspace into greater/lesser number of dimensions, so the I/O can proceed in a faster way. These changes also contain several bug fixes and _lots_ of code cleanups to the MPI datatype creation code. Many other misc. code cleanup are included as well...

| | | | | | | | | | | | | | | | | | | | | | | Commit metadata tagging framework. Description: This check-in contains a new framework whose goal is to apply a tag value to each new entry in the metadata cache as it is created. This tag value is such that it relates each piece of metadata to the HDF5 object that it belongs to (dataset, group, et cetera). This changeset includes the framework that applies the tags as well as a suite of tests to verify correct tag application, though does not yet make use of the tag values to flush/evict individual objects. Please refer to the "flush/evict individual objects" RFC for further discussion of these changes. Tested: jam, amani, linew (h5committest) liberty, abe, blue print

Formerly, it would loop over all chunks, checking to see if each existed in cache and on disk, causing major performance issues with large numbers of chunks. Tested: jam, linew, amani (h5committest)

* | [svn-r17977] Bug fix for 1584. H5Tdetect_class said a VL string is a string ↵Raymond Lu2009-12-091-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | type. But when it's in a compound type, it says it's a VL type. We want to tell user a VL string is a string. But internally we treat it as a VL type. I added a flag as a parameter of H5T_detect_class. It tells whether the caller is the public function H5Tdetect_class. I also added a detection for VL string in the private function for the compound case (or array or nested VL type). Tested on jam and amani - I tested the same change for 1.8 with h5committest.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Omnibus raw data I/O revisions, with wide-ranging changes and refactoring, in order to prepare for implementing "fast append" feature. These changes remove the majority of the code duplication for raw data I/O which has crept in over the last ten years and introduces a more object- oriented design for operating on different types of dataset storage. Chunked storage no longer has it's own I/O routines, it is now handled as either contiguous (if chunk is not pulled into the cache) or compact (if the chunk is cached in memory).

* [svn-r14096] There're 3 changes in this checkin as below:Raymond Lu2007-08-201-0/+24
| | | | | | | | | | | | | | | | | | 1. In H5Dwrite and H5Dread, let the data buffer point to a fake address if the application passes in an empty buffer. This is mainly for MPIO programs that some processes may not have any data to write or read but still participate the I/O. This solution solves some MPI's problem like the ChaMPIon on tungsten which doesn't support empty buffer. 2. The ChaMPIon on tungsten doesn't support complex derived MPI data type correctly and collective I/O when some processes don't have any data to write or read correctly. Detect the compiler "cmpicc" in the system-specific config file and set the variables for these two cases to false. The PHDF5 library already has set up a way to switch collective chunked I/O to independent under these two cases. 3. A bug fix - During the work of the optimization for compound data I/O, the case for switching collective chunked I/O to independent I/O was leftout. Fixed it by adding I/O caching to it in H5D_multi_chunk_collective_io in H5Dmpio.c. Tested on tungsten, cobalt, and kagiso for parallel; on linew and smirom for serial.
* [svn-r14031] Bug fix. Chunk address wasn't passed into some I/O functions ↵Raymond Lu2007-07-311-2/+2

* [svn-r13997] Moved H5D_istore_lock and H5D_istore_unlock from ↵Raymond Lu2007-07-211-15/+138
| | | | | | | | | H5D_istore_writevv and H5D_istore_readvv to H5D_chunk_write and H5D_chunk_read to avoid frequent lock and unlock and to improve some performance. Tested with h5committest on THG machines.
* [svn-r13918] Description:Quincey Koziol2007-06-261-248/+4
| | | | | | | | | | Refactor fill value buffer code into one location, for better long-term maintenance. Tested on: Mac OS X/32 10.4.10 (amazon) Linux/32 2.6 (chicago) Linux/64 2.6 (chicago2)

* [svn-r13884] The second step of optimization for compound data for the ChicagoRaymond Lu2007-06-191-42/+321
| | | | | | | | | | | | | | | | | | | | | | | | | | company. The I/O is optimized when the source and destination members are a subset of each other one way or another, and the order is the same, and no conversion is needed. For example: struct source { struct destination { TYPE1 A; --> TYPE1 A; TYPE2 B; --> TYPE2 B; TYPE3 C; --> TYPE3 C; }; TYPE4 D; TYPE5 E; }; or struct destination { struct source { TYPE1 A; --> TYPE1 A; TYPE2 B; --> TYPE2 B; TYPE3 C; --> TYPE3 C; }; TYPE4 D; TYPE5 E; }; The optimization is simply moving data from the source to the appropriate places in the buffer and bypass the reading of the background data and data conversion. Tested on smirom, liberty, sol, and copper.

| | | | | | | | | | Fix writing variable-length datatype fill values for contiguous dataset storage Tested on: Mac OS X/32 10.4.9 (amazon) Linux/32 2.6 (chicago) Linux/64 2.6 (chicago2)
* [svn-r13842] Description:Quincey Koziol2007-06-081-2/+3
| | | | | | | | | | | | Fix compact dataset storage to initialize VL datatype fill values correctly. Also, fix bug in global heap code when the fix action on a global heap is to delete an object in a heap with no free space. Tested on: Mac OS X/32 10.4.9 (amazon) FreeBSD/32 6.2 (duty)
* [svn-r13825] Description:Quincey Koziol2007-05-311-7/+15
| | | | | | | | | Incremental step forward in fixing problems with fill values that have a variable-length daattype. This set of changes fixes problems with the copying the property list values. tested Tn: Mac OS X/32 10.4.9 (amazon)
* [svn-r13816] Description:Quincey Koziol2007-05-291-29/+33

| | | | | | | | Minor code cleanups... Tested on: FreeBSD/32 6.2 (duty) Too minor to require h5committest
* [svn-r13531] When a dataset is created and no data is written, but fill ↵Raymond Lu2007-03-201-21/+77
| | | | | | | | | | | | value is defined, if there's VL type of data in the dataset, the address of the data is copied multiple times into the buffer, causing some trouble when the data is released. Instead, this checkin makes multiple copies of fill value first, then does conversion on each element so that each of them has a copy of the VL data. A test is added, too. Tested it on kagiso, sol, and copper.
* [svn-r13475] There's a configure issue linking szip's shared libraries when ↵Mike McGreevy2007-03-081-2/+2
| | | | | | | | | | | | running on kagiso. The static szip libraries are working as intended, but when shared szip libraries are present and intended for use they cannot be opened. A check has been implemented to test if shared szip libraries are functional on current platform. If they are not, and the user is trying to use them, szip is now disbaled and the user is informed. This issue occurs on kagiso, and the resolution was tested on kagiso.
* [svn-r13253] Updated all C and C++ style source code files with the THG ↵Albert Cheng2007-02-071-2/+3
| | | | | | | | | copyright notice. Tested platform: Kagiso only since it is only a comment block change. If it works in one machine, it should work in all, I hope. Still need to check the parallel build on copper.
* [svn-r13167] Description:Quincey Koziol2007-01-221-93/+88
| | | | | | | | | | | Get rid of two different types of fill value struct (merge H5O_fill_t and H5O_fill_new_t) and clean up & simplify dataset initialization code. (In preparation for shared object header message method call refactoring). Tested on: FreeBSD/32 6.2 (duty) Mac OS X/32 10.4.8 (amazon)

| | | | | | | | | haven't been run in a while, so many of the source files were updated with tracing macros, etc. No code changes by me. Tested on kagiso and smirom.
