| | | | | | multiple referring H5F_t on the EOT queue. This stops the VFD SWMR writer from advancing the shadow file's tick number too fast when we're using virtual datasets (VDS) with VFD SWMR.
* 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.
* Add a second bool argument to H5F_vfd_swmr_writer_end_of_tick() thatDavid Young2020-04-211-1/+1
| | | | | | | | | | | | | | | tells whether the call may wait for the reader tick to catch up. Add stub routines vfd_swmr_writer_may_increase_tick_to() and vfd_swmr_reader_did_increase_tick_to() for tests---e.g., vfd_swmr_zoo_writer/_reader---to use to coordinate their tick numbers. vfd_swmr_writer_may_increase_tick_to(new_tick, wait_for_reader) returns true if the writer may increase its tick number to `new_tick` without overrunning the reader. A reader uses vfd_swmr_reader_did_increase_tick_to() to tell a writer that its tick number has increased.

H5FDvfd_swmr_private.h. Perform tick processing in FUNC_ENTER_API_NOCLEAR, where it was missing. Track the number of times the HDF5 library has been entered/exited through its public API. Only perform tick processing on the first entry and last exit. This stops us from performing tick processing in API calls invoked by application callbacks. Performing tick processing in nested API calls led to crashes. Note well: FUNC_LEAVE_API now performs tick processing even on an error exit! Previously, it did not. I'm not sure if the change is ok.
