* [svn-r27768] Description:Quincey Koziol2015-09-141-2/+2
| | | | | | | | | | | | | | | | | | | | | | Complete revamp of package initialization/shutdown mechanism in the library. Each package now has a single init/term routine. This new way should avoid packages being re-initialized during library shutdown and is also be _much_ more proactive about giving feedback for resource leaks internal to the library. Introduces a new "module" header file for packages in the library (e.g src/H5Fmodule.h) which sets up some necessary package configuration macros for the FUNC_ENTER/LEAVE macros. (The VFL drivers have their own slightly modified version of this header, src/H5FDdrvr_module.h) Also cleaned up a bunch of resources leaks all across the library and tests, along with addressing many warnings, as I encountered them. Tested on: MacOSX/64 10.10.5 (amazon) w/serial & parallel Linux/64 3.10.x (kituo) w/serial & parallel Linux/64 2.6.x (ostrich) w/serial
* [svn-r27428] Bug fix: DAILYTEST-170Albert Cheng2015-07-241-0/+33
| | | | | | | | | | | | | | | | | | | Description: XL compilers in ostrich (PowerPC64 linux) fail in test/dt_arith because of the removal of the LLONG_TO_LDOUBLE_CORRECT (removed in r26625) and LDOUBLE_TO_LLONG_ACCURATE (removed in r26623). Solution: Reverse revisions r26623: bring back LDOUBLE_TO_LLONG_ACCURATE configure macro r26625: bring back LLONG_TO_LDOUBLE_CORRECT configure macro r26627: bring back WANT_DATA_ACCURACY configure macro which is used together with the above two macros. This also brings back the enable-dconv-accuracy configure option. Tested: h5committested. Also tested in ostrich using the XL compilers.

* [svn-r17760] Purpose: Fix problem with H5TB APINeil Fortner2009-10-271-0/+2
| | | | | | | | | | | Description: The H5TB API makes some improper assumptions about the order of compound datatype members. Namely, it assumes that members remain in the order in which they were inserted. Unfortunately, this assumption is inherent in the design of the interface. The library has been patched so that this assumption holds in situations relevant to H5TB. Tested: jam, linew, amani (h5committest)

| | | | | | | | | | unsigned long to float in the configure.in. The Pathscale compiler on Sandia's Linux machine misinterprets the values of unsigned long as negative during the conversion to float, when the first bit of unsigned long is on. Tested on jam. Need to test it on Sandia's machine.
* [svn-r15682] Purpose: fix bug 1298Neil Fortner2008-09-221-2/+2
| | | | | | | | | | | Description: The optimized "subset" compound conversion function would improperly copy the "blank" space at the end of compound types. Modified H5T_conv_struct_init to detect when the subset type has extra space at the end, and calculate the size of the data that should be copied into the conversion buffer for each element. Changes to the functions that implement these conversions. Tested: kagiso, linew, smirom (h5committest)

* [svn-r13884] The second step of optimization for compound data for the ChicagoRaymond Lu2007-06-191-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | 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.
* [svn-r13753] Description:Quincey Koziol2007-05-141-1/+1
| | | | | | | | | | | | | Check in "unique, but sharable" optimization to ISOHM code, which allows object header messages that are only used in one object to remain in the sole user's header, but migrates messages that are used in more than one header into the ISOHM heap.

* [svn-r12902] Checkin of Shared Object Header Message work.James Laird2006-11-131-4/+2
| | | | | | | | | | | | This feature is still in progress; Shared Object Header Messages are not complete as a feature and are not thoroughly tested. There are still "TODO" comments in the code (comments with the word "JAMES" in them, so as not to be confused with other TODO comments). Hopefully this checkin will reduce the liklihood of conflicts as I finish implementing this feature. All current tests pass on juniper, copper (parallel), heping, kagiso, and mir.
* [svn-r12736] Description:Quincey Koziol2006-10-091-5/+4
| | | | | | | | | | | | | | | | | | | Add "use the latest format" support for dataspace object header encode/ decode routines and clean up format a bit for the latest format (new to 1.8.x releases) Remove storing 'perm' parameter for array datatypes in memory and the file, and add test to make certain that if any user applications are attempting to store them, we get some reports back. (Should be unlikely, since the RefMan says that the parameter is not implemented and is unsupported). Carry those changes into the tests, etc. Clean up a bunch more compiler warnings.

* [svn-r12435] Purpose: Bug fixRaymond Lu2006-06-231-2/+11
| | | | | | | | | | | | Description: Mac OS 10.4 on PowerPC chip has some errors to convert (unsigned) long long to long double. When the bit sequences are 0x003ff..., 0x007fff..., 0x00ffff..., 0x01ffff..., 0x7fffff..., the converted values are twice as big as they should be. Solution: Detect the error in configure and disable the compiler conversion and test case. Platforms tested: h5committest, Mac OS 10.4, and fuss.
* [svn-r12425] Purpose: Bug fixRaymond Lu2006-06-201-6/+7
| | | | | | | | | | | | | | | Description: Data conversion from long double to (unsigned) long long returns some incorrect values on Mac OS 10.4 and SGI IRIX64 6.5. The conversions start to go wrong when the long double is 20041683600089727.779961 (0x4351ccf385ebc8a0bfcc2a...). If adjusting the values higher by assigning 0x...c8a0cf... or 0x...c8a0df..., the converted values go wild. Solution: Detect this error in configure.in and disable compiler conversions from long double to (unsigned) long long for Mac OS 10.4 and IRIX64 6.5. Platforms tested: h5committest, Mac OS 10.4, and IRIX64 6.5.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | New feature Description: Check in baseline for compact group revisions, which radically revises the source code for managing groups and object headers. WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! This initiates the "unstable" phase of the 1.7.x branch, leading up to the 1.8.0 release. Please test this code, but do _NOT_ keep files created with it - the format will change again before the release and you will not be able to read your old files!!! WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! Solution: There's too many changes to really describe them all, but some of them include: - Stop abusing the H5G_entry_t structure and split it into two separate structures for non-symbol table node use within the library: H5O_loc_t for object locations in a file and H5G_name_t to store the path to an opened object. H5G_entry_t is now only used for storing symbol table entries on disk. - Retire H5G_namei() in favor of a more general mechanism for traversing group paths and issuing callbacks on objects located. This gets us out of the business of hacking H5G_namei() for new features, generally. - Revised H5O* routines to take a H5O_loc_t instead of H5G_entry_t - Lots more... Platforms tested: h5committested and maybe another dozen configurations.... :-)

| | | | | | | | | | | | | | | | | | | | | Code cleanup Description: Merge back changes from "compact group" work that improve the infrastructure of the library and may impact others. In this round of merging, that includes: - Move datatype allocation into single internal routine, instead of duplicated code that was spread out in a dozen or so places. - Clean up guts of object header routines (H5O_*) to allow for some of the fancieroperations that need to be performed on groups, along with some general improvements. - Added a new error code - Some minor cleanups in other code....

* [svn-r11332] Purpose: Minor Change to Macro NamesRaymond Lu2005-09-011-26/+26
| | | | | | | | | Description: Changed the names of macros defined in H5Tpkg.h from H5T_CONV_INTERIM_XXX_XXX to H5T_CONV_INTERNAL_XXX_XXX to be more descriptive. Platforms tested: fuss - simple change
* [svn-r11317] Purpose: Minor change to macro namesRaymond Lu2005-08-301-13/+13
| | | | | | | | | | | | Description: Changed the names of the interim macros for data conversion checked in yesterday from the SOURCE_DESTINATION style (like FP_FP or LDOUBLE_LLONG) to the H5T_CONV_INTERIM_SOURCE_DESTINATION style (like H5T_CONV_INTERIM_FP_FP OR H5T_CONV_INTERIM_LDOUBLE_LLONG), to be more descriptive. These macros are defined in H5Tpkg.h and used in H5Tconv.c and H5T.c for interim purpose. Platforms tested: fuss - simple change.
* [svn-r11311] Purpose: New features.Raymond Lu2005-08-291-0/+96
| | | | | | | | | | | | | | | | | | | | Description: Added 2 new configure options, --enable-exception and --enable-accuracy. --enable-exception lets the library check whether user's exception handling functions are present during compiler data conversions and use them if they are. When it's disabled, this step is skipped to improve conversion speed. This step isn't implemented yet for soft conversions because there would be little gain in speed. --enable-accuracy guarantees data accuracy during data conversions. It means the library will choose compiler conversions only if the accurate data is secured. Otherwise, the library will go for the library's own conversions. If this option is disabled, the library uses compiler conversions in favor of their speed as long as they work even if data can be incorrect. Platforms tested: h5committest and fuss. Some systems may fail after this checkin.
