* [svn-r8682] Purpose: Take out unnecessary stepRaymond Lu2004-06-141-4/+0
| | | | | | | | | Description: I put function call of H5T_lock in H5T_open in last checkin. It's unnecessary. Solution: Take out. Platforms tested: eirene(simple change).
* [svn-r8680] Purpose:Quincey Koziol2004-06-141-16/+31
| | | | | | | | | | | | | Code optimization Description: Detect when a default property list is being used and just copy over the default VL allocation properties, instead of querying for them. Platforms tested: Solaris 2.7 (arabica) FreeBSD 4.10 (sleipnir) w/parallel Too minor to require h5committest
* [svn-r8678] Purpose:Quincey Koziol2004-06-1410-283/+186
| | | | | | | | | | | | | | | | | | | Code cleanup & optimization Description: Remove old structures that used a union to store information about the dataspace extent and just store the information directly in the dataspace extent itself. Remove ifdef'd references to permutation ordering in dataspaces. We'll definitely need more than this code if/when we implement this feature. Change allocation of dataspace information from calloc() to malloc(). Platforms tested: Solaris 2.7 (arabica) FreeBSD 4.10 (sleipnir) w/parallel Too minor to require h5committest
* [svn-r8676] Purpose:Quincey Koziol2004-06-136-358/+310
| | | | | | | | | | | | | | | Code optimization Description: Using existing dataspace extent copying routine instead of duplicating the code (more slowly). Also, back-port improvements to the dataspace message reading which clean up the clean and centralize operations. Platforms tested: Solaris 2.7 (arabica) FreeBSD 4.10 (sleipnir) w/parallel Too minor to require h5committest
* [svn-r8674] Purpose:Quincey Koziol2004-06-1315-490/+565
| | | | | | | | | | | | | | | | | | Code optimization Description: Revised dataspace selections to use a more "object oriented" mechanism to set the function pointers for each selection and selection iterator. This reduces the amount and number of times that dataspace selection info has to be copied. Additionally, change hyperslab selection information to be dynamically allocated instead of an inline struct. Platforms tested: Solaris 2.7 (arabica) FreeBSD 4.10 (sleipnir) w/parallel Too minor to require h5committest
* [svn-r8671] Purpose:Quincey Koziol2004-06-133-16/+128
| | | | | | | | | | | | | Code optimization Description: Avoid a memory copy by directly reading from the variable-length sequence buffer when there is no type conversion on the way to disk. Platforms tested: Solaris 2.7 (arabica) FreeBSD 4.10 (sleipnir) w/parallel Too minor to require h5committest
* [svn-r8669] Purpose:Quincey Koziol2004-06-131-54/+63
| | | | | | | | | | | | | | Code optimization Description: Avoid running conversion routine when it's a noop. Also, pick a minimum size for the variable-sized sequence conversion buffer, instead of allocating lots of small buffers. Platforms tested: Solaris 2.7 (arabica) FreeBSD 4.10 (sleipnir) w/parallel
* [svn-r8667] Purpose:Quincey Koziol2004-06-135-296/+324
| | | | | | | | | | | | | | | | Code optimization Description: Restructure conversion loop of variable-length objects to avoid walking through memory backwards and allocating as many temporary buffers. (This uses the optimized method used in the atomic type conversions). Also bring back another optimization for variable-length datatypes that avoids querying the DXPL so many times. Platforms tested: Solaris 2.7 (arabica) FreeBSD 4.10 (sleipnir) w/parallel Too minor to require h5committest
* [svn-r8665] Purpose:Quincey Koziol2004-06-125-380/+694
| | | | | | | | | | | | | | Code optimization Description: Allow global heap collections to grow in size (up to a 64K limit) if they are able to. This allows them to grow to a more reasonable size than the 4K minimum size. Platforms tested: Solaris 2.7 (arabica) FreeBSD 4.10 (sleipnir) w/parallel Too minor to require h5committest
* [svn-r8663] *** empty log message ***Raymond Lu2004-06-113-4/+23

* [svn-r8657] Purpose:Quincey Koziol2004-06-111-5/+6
| | | | | | | | | | | | | Code optimization Description: Eliminate redundant memory allocation for type conversion of variable-length sequences. Platforms tested: Solaris 2.7 (arabica) FreeBSD 4.10 (sleipnir) w/parallel Too minor to require h5committest
* [svn-r8652] Purpose:Quincey Koziol2004-06-101-3/+3
| | | | | | | | | | | Code optimization Description: Eliminate redundant memset() when creating chunk map structure. Platforms tested: Solaris 2.7 (arabica) FreeBSD 4.10 (sleipnir) w/parallel
* [svn-r8649] Purpose:Quincey Koziol2004-06-102-14/+6
| | | | | | | | | | | | | Code optimization Description: Eliminate some operations through temporary variables in H5F_addr_encode. Eliminate some redundant memset()'s of structures that will be completely overwritten in the variable-length datatype code. Platforms tested: Solaris 2.7 (arabica) FreeBSD 4.10 (sleipnir) w/parallel
* [svn-r8640] Purpose:Quincey Koziol2004-06-091-1/+1
| | | | | | | | | | | | Code optimization Description: Call malloc() instead of calloc() for data structure that we completely initialize. Platforms tested: Solaris 2.7 (arabica) FreeBSD 4.10 (sleipnir) w/parallel
* [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.

* [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: Expand the use of macros to inline trivial function pointer lookup and calls to reduce the overall number of functions invoked during normal operation of the library.

* [svn-r8519] Purpose:Quincey Koziol2004-05-134-58/+16
| | | | | | | | | | | | Code optimization Description: Don't make a separate allocation for the selection offset - incorporate it into the selection structure as a fixed size array. Platforms tested: Solaris 2.7 (arabica) FreeBSD 4.9 (sleipnir) w/parallel
* [svn-r8514] Purpose:Quincey Koziol2004-05-132-148/+10

* [svn-r8512] Purpose:Quincey Koziol2004-05-133-9/+69
| | | | | | | | | | | | 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-r8497] Purpose:Quincey Koziol2004-05-088-27/+47
| | | | | | | | | | | | | Code optimization Description: Further reduce the number of copies we make of a hyperslab selection for chunked I/O, especially when we are only going to throw the old selection away for a new one. Platforms tested: Solaris 2.7 (arabica) FreeBSD 4.9 (sleipnir) w/parallel
* [svn-r8475] Purpose:Quincey Koziol2004-05-031-26/+36

* [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
