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.... :-)

| | | | | | | | | | | | | | | | | | | New feature Description: Add in baseline "object copy" code from Peter [in the form of a new API routine: H5Gcopy()]. There's still some work to do (like handling variable- length datatypes and possibly support for references) and it hasn't been tested on mounted files yet, but the core functionality is there and working correctly. I've also got a set of patches to update the 1.6 branch with tweaks to keep the branches mostly in sync, but Elena will kill me if I import them before the 1.6.5 release is out... :-) Platforms tested: FreeBSD 4.11 (sleipnir) h5committested

It's not quite ready for "prime time" yet, but it's close enough to be useful.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Bug Fix/Code Cleanup/Doc Cleanup/Optimization/Branch Sync :-) Description: Generally speaking, this is the "signed->unsigned" change to selections. However, in the process of merging code back, things got stickier and stickier until I ended up doing a big "sync the two branches up" operation. So... I brought back all the "infrastructure" fixes from the development branch to the release branch (which I think were actually making some improvement in performance) as well as fixed several bugs which had been fixed in one branch, but not the other. I've also tagged the repository before making this checkin with the label "before_signed_unsigned_changes".

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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-r9183] Purpose: New featureRaymond Lu2004-09-011-2/+2
| | | | | | | | | | | | Description: Restore 6 old error API functions back to the library to be backward compatible with v1.6. They are H5Epush, H5Eprint, H5Ewalk, H5Eclear, H5Eset_auto, H5Eget_auto. These functions do not have error stack as parameter. Solution: Internally, these functions use default error stack.

| | | | | | | | | | | | | | | Bug fix (sorta) Description: Change reading of "missing" chunks from datasets with undefined fill values to not overwrite the application buffer with random garbage from memory.

* [svn-r9101] Purpose:Quincey Koziol2004-08-171-8/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Bug fix Description: 1 - Dataset contiguous storage cache information had a bug where it was possible to try to access invalid cache information if the cache wasn't filled the first time it attempted to loop through the list of offset/length vectors. 2 - Additionally, the contiguous storage cache information was being used in certain circumstances from the chunked dataset I/O code path, which was generally fatal since the chunk storage and contiguous storage information were stored together in a union. Solution: 1 - Avoid special case of first trip through loop over offset/length I/O vectors and always check for the contiguous storage sieve buffer buffer being NULL. 2 - Change the union containing the chunk and contiguous storage cache information into a struct, allowing both to be used at the same time.

| | | | | | | | | | | | | | | | | | | | | | | | Bug fix. Description: Address two problems: - The computation of the scanline in the szip filter was being performed in the "can apply" callback routine instead of the "set local" routine. - The routine which allocated all the chunks for an entire dataset (which is invoked when the allocation time is early or late, rather than incremental) wasn't recording a failed filter in the information for the chunk, causing the library to believe that the chunk had the filter applied when it really hadn't. Solution: - Move the scanline computation to the "set local" callback. - Record the filter mask with each chunk created when allocating them.

| | | | | | | | | | | | | | | | | | Code cleanup, sorta Description: Added ifdef sections for "H5_USING_PURIFY" in various places in the code, which are designed to reduce the spurious "uninitialized memory read" warnings from purify which are actually OK. Note that this macro will have to be turned on by adding it to the CFLAGS for the build - I didn't think it was important enough to add a configure flag for. Also, the changes in H5HG.c optimize the walks through the objects in a heap to only look at the 'used' entries instead of all the 'allocated' entries.

| | | | | | | | | | | | | | | | | | | | | | | Adding the first round of patches about supporting collective chunk IO in HDF5 Description: The current HDF5 library doesn't support collective MPIO with chunk storage. When users set collective option in their data transfer with chunk storage, the library silently converted the option to INDEPENDENT and that caused trememdous performance penalty. Some application like WRF-parallel HDF5 IO module has to use contiguous storage for this reason. However, chunking storage has its own advantage(supporting compression filters and extensible dataset), so to make collective MPIO possible inside HDF5 with chunking storage is a very important task. This check-in make collective chunk IO possible for some special cases. The condition is as follows(either case is fine with using collective chunk IO) 1. for each process, the hyperslab selection of the file data space of each dataset is regular and it is fit in one chunk. 2. for each process, the hyperslab selection of the file data space of each dataset is single and the number of chunks for the hyperslab selection should be equal. Solution: Lift up the contiguous storage requirement for collective IO. Use H5D_isstore_get_addr to get the corresponding chunk address. Then the original library routines will take care of getting the correct address to make sure that MPI FILE TYPE is built correctly for collective IO> Platforms tested: arabica(sol), copper(AIX), eirene(Linux) parallel test is checked at copper.
