| | | | | | | | | | | | | | | | | | | | | | (2) A temporary fix to address the test/objcopy.c: test_copy_group_deep() test failure with the family driver. The test failure occurs with these configurations in objcopy.c: --with shared src messages (CONFIG_SHARE_SRC) --without shared dst messages (CONFIG_SHARE_DST) --with latest format for source file (CONFIG_SRC_NEW_FORMAT) --without dense attributes (CONFIG_DENSE) --with latest format for destination file (CONFIG_DST_NEW_FORMAT) The temporary fix is in src/H5MFaggr.c (see comments above #ifdef REPLACE/#endif).

* | Add all extant virtual files to a list. Add an "exclusive owner" (`exc_owner`)David Young2020-07-101-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | member to all virtual files. Add a routine, H5FD_has_conflict(), that returns true if a new virtual file is identical to an existing virtual file that has an exclusive owner. Establish an exclusive owner for a VFD SWMR virtual file's lower virtual file. Rename bsdqueue.h to H5queue.h and install it, since it's used by H5FDpublic.h. This is part of a changeset that helps us avoid creating multiple H5F_shared_t for one file when virtual datasets are used with VFD SWMR. The old code for deduplicating VFD SWMR H5F_shared_t instances did not work correctly with VFD SWMR, so we'd end up with multiple H5F_shared_t all active on the same file.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | eventually reclaimed. Defer reclamation of raw data filespace, only. XXX Deferring only raw-data reclamation isn't *quite* sufficient because XXX a writer could conceivably reuse metadata space as raw-data space XXX before max_lag ticks have elapsed. Readers could see metadata XXX corrupted by raw data. Once a file starts to close, stop deferring reclamation. In H5MF_free_aggrs(), perform all deferred reclamations if the file is closing.

* | In process_deferred_frees(), remove *all* deferred frees from theDavid Young2020-02-181-2/+5
| | | | | | | | | | | | | | | | | | | | | | H5F_shared_t's queue before processing any, instead of removing just one, processing it, removing another, processing it, and so on. While we processed the first entry on the queue, we often called H5MF_xfree() again, which called process_deferred_frees() again, which processed the first entry, calling H5MF_xfree() again, and on and on, until the deferred frees list was exhausted. This deep recursion showed up as a wide, tall stack in my flame graphs. Taking all deferred entries off of the queue to start definitely breaks the recursion and saves processing time.
* | Rename the deferred-free queues. There are two of them, and the names I usedDavid Young2020-02-061-5/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | for them did not help me keep track of what they were for. For brevity, I will call a deferred free record a "defree" in the code. The deferred_free_queue_t becomes a lower_defree_queue_t, and each record on the queue becomes a lower_defree_t. A lower_defree_t tracks one deferred free on the lower VFD---that is, the one under the SWMR VFD. The old_image_queue_t becomes a shadow_defree_queue_t, and a record therein is a shadow_defree_t. A shadow_defree_t tracks one deferred free on the shadow file.

* | Initial checkin of page buffer re-implementation to support VFD SWMR.mainzer2018-11-041-1/+1
|/ | | | | | | | | | | | | | | | | | | | | | Tested serial / debug on Charis and Jelly. Two known issues: 1) New page buffer seems to expose issues in the accumulator code. For whatever reason, fheap with the new page buffer exposes corruption issues if the page buffer uses H5F__accum_read/write(), but the problems go away if the page buffers uses H5FD_read/write() instead. Need to either chase this or dis-able page bufffer in combination with the accumulator. 2) Encountered a number of assertion failures that are explainable by the free space manager code not telling the page buffer to discard pages when they are freed. Wrote code to handle this -- once the free space manager is modified, this code should be removed and the original assertions restored.
