* Add Splitter VFD to library.Jacob Smith2020-03-131-0/+2
| | | | | | | | | | | | | | | * "Simultaneous and equivalent" Read-Write and Write-Only channels for file I/O. * Only supports drivers with the H5FD_FEAT_DEFAULT_VFD_COMPATIBLE flag for now, preventing issues with multi-file drivers. Add Mirror VFD to library. * Write-only operations over a network. * Uses TCP/IP sockets. * Server and auxiliary server-shutdown programs provided in a new directory, `utils/mirror_vfd`. * Automated testing via loopback ("remote" of localhost).
* * Added new public H5FDdriver_query() API call.Dana Robinson2017-05-241-0/+3
| | | | | | * Changed return type of H5FD_driver_query() to herr_t. * Updated swmr.c to use H5FDdriver_query() instead of the private call. * Added some flags tests to vfd.c.
* Fixed HDFFV-10214:Dana Robinson2017-05-191-0/+8
| | | | | | | | | | | | * Updated comments in the library to accurately reflect the semantics of the H5FD_FEAT_POSIX_COMPAT_HANDLE flag. * Removed the check for the POSIX compatible handle feature flag when determining if a VFD supports SWMR. Partial work for HDFFV-10197: * Added a new H5FD_FEAT_DEFAULT_VFD_COMPATIBLE feature flag that is set when a VFD creates output that is compatible with the default VFD. Will be used in the testing but might also be generally useful to users.

| | | | | | | | | | | | 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-r12700] Alert:Quincey Koziol2006-10-021-9/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | File format is not stable, don't keep files produced! Description: First stage of checkins modifying the format of groups to support creation order. Implement "dense" storage for links in groups. Try to clarify some of the symbols for the H5L API. Add the H5Pset_latest_format() flag for FAPLs, to choose to use the newest file format options (including "dense" link storage in groups) Add the H5Pset_track_creation_order() flag for GCPLs, to enable creation order tracking in groups (although no index on creation order yet). Remove --enable-group-revision configure flag, as file format issues are now handled in a backwardly/forwardly compatible way. Clean up lots of compiler warnings and other minor formatting issues.

| | | | | | | | | | | Code cleanup Description: Clean up various warnings reported by the Windows team. Platforms tested: FreeBSD 4.11 (sleipnir) Too minor to require h5committest
* [svn-r10506] Purpose:Quincey Koziol2005-03-291-0/+8
| | | | | | | | | | | | New feature Description: Add first iteration of "segmented heap" code, which will be used to store links in groups in a more flexible way than the previous "local heap" mechanism. Platforms tested: FreeBSD 4.11 (sleipnir) w/parallel Solaris 2.9 (shanti)
* [svn-r10184] Purpose:Quincey Koziol2005-03-111-0/+5
| | | | | | | | | | | | | | | | | | | | New feature Description: Add new "block tracker" data structure to library, for tracking blocks of bytes in a file. Block trackers will be used to keep track of the blocks belonging to the soon-to-be-implemented "segmented heap" which is designed to replace the current local & global heaps (starting with the local heap). Block trackers will also keep track of the free space in the segmented heap and someday could be used to track the free space in the entire HDF5 file. They are implemented as a small header of information to cache the state of the blocks (max & min sizes of blocks tracked, etc.) and the records of the blocks themselves are stored in a v2 B-tree. Platforms tested: FreeBSD 4.11 (sleipnir) Solaris 2.9 (shanti) h5committest
* [svn-r8877] James Laird2004-07-141-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | Purpose: Bug Fix Description: If an HDF5 file grows larger than its address space, it dies and is unable to write any data. This is more likely to happen since users are able to change the number of bytes used to store addresses in the file. Solution: HDF5 now throws an error instead of dying. In addition, it "reserves" address space for the local heap and for object headers (which do not allocate space immediately). This ensures that after the error occurs, there is enough address space left to flush the entire file to disk, so no data is lost. A more complete explanation is at /doc/html/TechNotes/ReservedFileSpace.html Platforms tested: sleipnir, copper (parallel), verbena, arabica, Windows (Visual Studio 7) Solution: Platforms tested: Misc. update:
* [svn-r7317] Purpose:Quincey Koziol2003-08-081-1/+1
| | | | | | | | | | | | | | | | Feature change & code cleanup Description: Changed fileno field in H5FD_t struct from 'unsigned long[2]' to just 'unsigned long'. Changed over code to handle the fileno change. Chased error API changes Platforms tested: h5committested
* [svn-r6500] Purpose:Bill Wendling2003-03-191-57/+87
| | | | | | | | | | | | New Feature Description: Added function pointers for the lock and unlock functions. Platforms tested: Linux, Modi4, Sol Misc. update:
* [svn-r6391] Purpose:Bill Wendling2003-02-101-3/+0
| | | | | | | | | | Fix Description: The extra field I put in this structure wasn't needed. Solution: Placed it in the file driver's structure instead. Platforms tested: Linux
* [svn-r6387] Purpose:Quincey Koziol2003-02-101-7/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | Bug Fix Description: Metadata cache in parallel I/O can cause hangs in applications which perform independent I/O on chunked datasets, because the metadata cache can attempt to flush out dirty metadata from only a single process, instead of collectively from all processes. Solution: Pass a dataset transfer property list down from every API function which could possibly trigger metadata I/O. Then, split the metadata cache into two sets of entries to allow dirty metadata to be set aside when a hash table collision occurs during independent I/O. Platforms tested: Tested h5committest {arabica (fortran), eirene (fortran, C++) modi4 (parallel, fortran)} FreeBSD 4.7 (sleipnir) serial & parallel Misc. update: Updated release_docs/RELEASE
