* [svn-r9687] Purpose:John Mainzer2004-12-181-99/+10282
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Modify the cache code (H5C) to support automatic cache resizing to adapt to the work load at run time. Description: Different applications require different sized caches to maintain an acceptable hit rate. This set of changes attempts to provide the ability to adjust to circumstances automatically. Solution: Added highly configurable code to allow the user to either set a fixed cache size, or allow the cache to grow and shrink according to conditions. If enabled, cache size increases are triggered when the hit rate drops below a user specified threshold in a user specified interval. Cache size reductions (if enabled) are triggered when either the hit rate exceeds some user specified threshold over a user specified interval, when the cache contains "enough" entries that haven't been accessed for a user specified interval, or some mix of the above. See the header comments on the H5C_auto_size_ctl_t structure in H5Cprivate.h for further details. At present, the cache resize configuration options are not accessible via the user API. Must add this. Platforms tested: h5committested, heping (serial), and copper (parallel) Misc. update:

| | | | | | | | | | | | | | | | Bug fix Description: Correct integer overflow situation for computing the size of a dataset. Solution: Rachet one of the dimensions down far enough that the total size of the dataset's raw data doesn't overflow a 64-bit int. Platforms tested: FreeBSD 4.10 (sleipnir) IRIX 6.?

* [svn-r9598] Purpose:Quincey Koziol2004-11-291-0/+22
| | | | | | | | | | | | | New internal feature Description: Add a "release" routine to the skip lists, which releases all the nodes in the skip list, but keeps the skip list active. Platforms tested: FreeBSD 4.10 (sleipnir) Linux 2.4 (verbena) Too minor to require h5committest
* [svn-r9596] Purpose:Quincey Koziol2004-11-291-0/+5
| | | | | | | | | | | | | Code optimization Description: Retarget metadata cache code from using TBBT routines to using new skiplist routines, for a reasonable speedup (when dealing with dirty metadata) Platforms tested: FreeBSD 4.10 (sleipnir) w/parallel Solaris 2.7 (arabica) Too minor to require h5committest
* [svn-r9580] Purpose:Quincey Koziol2004-11-274-7/+505
| | | | | | | | | | | | | | | | | | | | Add new internal data structure Description: Add an implementation of skip lists to the library (see comment in src/H5SL.c for references to the papers describing them) as a potential replacement for our current threaded, balanced binary tree container. Skip lists are much simpler to implement and should be faster to use. Also, added new error codes to release branch, so bump the minor version number to indicate that the library is no longer perfectly compatible with the 1.6.3 release. Platforms tested: FreeBSD 4.10 (sleipnir) w/parallel Solaris 2.7 (arabica) Too minor to require further testing (the skip lists aren't actually used by any library code yet)
* [svn-r9567] Purpose:Quincey Koziol2004-11-241-14/+14

* [svn-r9539] Raymond Lu2004-11-181-9/+4
| | | | | | | | | | | | | | | | | | Purpose: Correction to previous bug fix. This checkin is mainly to let user test his program. Description: For family driver bug(#213), the previous fix was imperfect. The problem was when user create family file, the member size information wasn't saved in file. When the file was re-opened, the library simply use the size of 1st member file as member size. Solution: When file is re-opened, member size passed in from access property is checked to see if it's reasonable. If there is only 1 member file, member size can't be smaller than current member size. If there are at least 2 member files, member size can only be equal to the 1st member size. Platforms tested: h5committest and fuss
* [svn-r9531] Purpose: Bug fix(#213)Raymond Lu2004-11-161-7/+30
| | | | | | | | | | | | | Description: H5Pset_fapl_family sets family member size only for creating new file. The file doesn't keep this size information. When the file is re-opened, the size of first member file is used as the member size. Solution: Assume user knows the original member size and sets it through H5Pset_fapl_family. That will be the member size. User can pass in value 0 as member size if he doesn't know the original member size. Library will choose the size of current first member size as the member file size. Platforms tested: h5committest and fuss.

| | | | | | | | | | | | | | Bug fix, sorta. Description: Revert change to H5Pget_data_transform() which changed len of buffer returned to be inconsistent with H5Iget_name(), etc. We should discuss this change and apply it to all the similar functions if we decide to change the return value.

* [svn-r9445] Purpose: Bug fixRaymond Lu2004-10-211-50/+50
| | | | | | | | | | | Description: "char" was considered as always "signed char" in data type conversion. However, ISO C leaves the definition of "char" to individual implementation. i.e. for IBM AIX C compiler, it's treated as "unsigned char". Solution: Changed all "char" to "signed char". Don't even do "char" anymore because its definition is up to each vendor. Platforms tested: h5committest

| | | | | | | | | | | | | | Bug fix. Description: If a subtest failed, the error would not propogate properly to the main function, thereby resulting in a succesful run, even though the test failed. Solution: Fixed error return values. The dtransform test will now fail for real. Platforms tested: sol + eirene + copper
* [svn-r9427] Purpose:Albert Cheng2004-10-141-1/+7
| | | | | | | | | | | | | | Bug fix. Description: AIX defines different sizes of the signed and unsigned int_fast8_t. Changed the code to check each type individually and do not verify they must be the same size. Platforms tested: Tested in copper only since the change is trivial. Misc. update:
* [svn-r9423] Purpose:Leon Arber2004-10-141-122/+469

| | | | | | | | | | | | | | tconfig.c: Verified only the unsigned int types and did not detect inconsistencies on signed type such as int_fast16_t. Changed code to verify both signed and unsigned int types wherever applicable. It also depends on signed and unsigned forms of an int type must be of the same sizes. testhdf5.c: Shorten the configure test name to 'config'--easier to type. Tested on LLNL Frost and Snow. Will test in Copper after commit.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Purpose: Feature Description: Datatypes and groups now use H5FO "file object" code that was previously only used by datasets. These objects will hold a file open if the file is closed but they have not yet been closed. If these objects are unlinked then relinked, they will not be destroyed. If they are opened twice (even by two different names), both IDs will "see" changes made to the object using the other ID. When an object is opened using two different names (e.g., if a dataset was opened under one name, then mounted and opened under its new name), calling H5Iget_name() on a given hid_t will return the name used to open that hid_t, not the current name of the object (this is a feature, and a change from the previous behavior of datasets). Solution: Used H5FO code that was already in place for datasets. Broke H5D_t's, H5T_t's, and H5G_t's into a "shared" struct and a private struct. The shared structs (H5D_shared_t, etc.) hold the object's information and are used by all IDs that point to a given object in the file. The private structs are pointed to by the hid_t and contain the object's group entry information (including its name) and a pointer to the shared struct for that object. This changed the naming of structs throughout the library (e.g., datatype->size is now datatype->shared->size). I added an updated H5Tinit.c to windows.zip.

* [svn-r9234] Purpose:Quincey Koziol2004-09-092-38/+4
| | | | | | | | | | | | | | | | | | | | | | | Code cleanup Description: Tweak recent "forward compatibility" changes to the H5E* API (which allowed for the old H5E API functions to remain unchanged) by allowing for the error stack callback function (H5E_auto_t) to also remain unchanged from the 1.6 branch. This required changing the H5E{get|set}_auto routines to have the old style H5E_auto_t type (which didn't have a stack ID parameter) and the new H5E{get|set}_auto_stack routines to have a newer "H5E_auto_stack_t" type (which has a stack ID parameter). This should make the H5E API changes as forwardly compatible as possible. One side-affect of this change was that it was impossible to determine if the current auto error callback was the old style (H5E_auto_t) or the new style (H5E_auto_stack_t) of callback, so a new API function (H5Eauto_is_stack) was adde to query this.

* [svn-r9221] Purpose: Bug fixRaymond Lu2004-09-081-1/+1
