* Let us override the examples directory using --with-examplesdir=DIR.David Young2020-05-201-0/+22
| | | | | | | | | This is handy for NetBSD where HDF5 examples are installed by convention in $prefix/share/examples/hdf5/ rather than in ${prefix}/share/hdf5_examples/, which is the HDF5 default. Place hdf5_examples/ under ${datarootdir} which on most systems will be ${prefix}/share/, anyway.

* In H5FD_vfd_swmr_read(), do not verify checksums on shadow entriesDavid Young2020-05-131-157/+63
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | that are longer than the buffer that the caller supplied: the checksum usually will fail, but that's not actually a fatal condition, and usually we will have another opportunity to verify the checksum. In H5FD_vfd_swmr_read(), remove a bunch of disused code. In H5FD_vfd_swmr_read(), do not re-read a shadow image that has a bad checksum, because a bad checksum indicates a serious problem (writer outran reader, OS defect, hardware failure) from which H5FD_vfd_swmr_read() cannot recover. Rationale: the writer write(2)s new shadow images before the new index, and the new index before the new header. In H5FD_vfd_swmr_read(), the reader has read(2) both the index and the header in full. POSIX semantics indicate that in these circumstances, the last shadow image write(2) MUST be completely visible when we read(2). That is, the index write(2) & read(2) and the header write(2) & read(2) pair cannot divide a preceding shadow-image write(2). The reader may see a "torn" image at this juncture if, for example, the writer got max_lag ticks ahead of it and reused the storage for this shadow image. Even if the reader "recovers" by re-reading the image until its checksum is correct, it cannot be sure that the image thus read is the right one for the HDF5 address passed to H5FD_vfd_swmr_read(), and it cannot be sure that the image thus read is not stale, because it's operating with an out-of-date shadow index. Add log outlets swmr_read, swmr_read_exception, and swmr_read_err. Log to `swmr_read` on entry to H5FD_vfd_swmr_read(), log to `swmr_read_exception` when checksums are skipped for exceptional conditions (page buffer not configured, buffer shorter than shadow image), and log to `swmr_read_err` when the checksum fails.
* When an entry changes size, remove it from the tick list and add it backDavid Young2020-05-111-0/+10

* Let catch_out_err_and_rc() callers redirect the standard input andDavid Young2020-04-281-2/+2

Move redirection of standard error output to the standard output stream outside of the curly braces, since usually I want to save the `echo` and `wait` output, too, and it makes the redirection of the supervised program a little easier to follow, I think.

* Add a `skip compact` configuration for skipping the "zoo" tests forDavid Young2020-04-214-102/+472
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | compact datasets. Bundle the zoo-test configuration into a new type, zoo_config_t. Add a couple new "zoo" test phases, "delete" and "validate-deletion", to the existing "create" and "verify" phases. Give names and numbers to all phases with the new `enum`, `phase_t`, and refactor so that tend_zoo runs a selection of phases at each step. Stub the "delete" and "validate-deletion" phases for most test steps. Actually implement for compact dataset (ds_cpt_i) test. In tend_zoo(), delay for 50 milliseconds after running all steps. Really, this should delay after each step.... Implement vfd_swmr_writer_may_increase_tick_to() and vfd_swmr_reader_did_increase_tick_to() with a file that reader and writer share. The reader saves its current tick number in the shared file. The writer does not advance its tick number past the reader's. Collect some statistics in vfd_swmr_writer_may_increase_tick_to() and print them before the writer exits. Add option flags for skipping compact dataset tests (-C) and for printing error stacks (-e). Update the usage message, which was stale before the new options were added. Delete some dead code. Add #if 0'd-out code for the reader to wait for the writer before running "delete" and "validate-deletion" steps.

* Add a second bool argument to H5F_vfd_swmr_writer_end_of_tick() thatDavid Young2020-04-217-17/+31
| | | | | | | | | | | | | | | 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.
