0.7

This release contains two contributions from @polytypic, incl. an STM feature to help testing of cmds that may raise an effect:

• #509: Change/Fix to use a symmetric barrier to synchronize domains
• #511: Introduce extended specs to allow wrapping command sequences
• #517: Add Lin combinators seq_small, array_small, and list_small

0.6

This version contains to changes to the qcheck-lin, qcheck-stm or qcheck-multicoretests-util packages
and hence isn't pushed to the opam-repo.

Instead the release contains two significant additions to the test suite in the multicoretests opam package:

• #463: Dynarray tests
• #469: Add gc tests

0.5

The biggest news in the 0.5 release is the addition of Util.Pp.pp_fun_ for printing function values generated with QCheck.
To ensure quoted and escaped output for chars and strings, this required bumping the qcheck-core lower bound to the freshly released qcheck-core.0.23. This in turn, enabled a couple of other clean-ups:

• #492: Also use the new, upstreamed Gen.exponential combinator in STM
• #491: Require qcheck.0.23, simplify show functions by utilizing it, and update expect outputs accordingly
• #486: Add Util.Pp.pp_fun_ printer for generated QCheck.fun_ functions

0.4

The 0.4 release brings two new "stress test" functions and also adjusts the cmd list distribution of STM_sequential:

• #415: Remove --verbose in internal mutable_set_v5 expect test to avoid a test failure on a slow machine
• #443: Add Lin_domain.stress_test as a lighter stress test, not requiring an interleaving search.
• #462: Add STM_domain.stress_test_par, similar to Lin_domain.stress_test for STM models.
• #472: Switch arb_cmds to use an exponential distribution with a mean of 10, avoiding lists of up to 10000 cmds in STM_sequential (reported by @nikolaushuber).

0.3

The 0.3 release brings 3 "usability improvements" to STM and Util
and a Lin search improvement that should reduce memory allocation.

• #400: Catch and delay exceptions in STM's next_state for a nicer UX
• #387: Reduce needless allocations in Lin's sequential consistency
  search, as part of an Out_channel test cleanup
• #379: Extend the set of Util.Pp pretty-printers and teach them to
  add break hints similar to ppx_deriving.show; teach to_show to
  generate truncated strings when $MCTUTILS_TRUNCATE environment
  variable is set
• #368: Switch STM_domain.agree_prop_par_asym from using
  Semaphore.Binary to using an int Atomic.t which improves
  the error rate across platforms and backends

0.2

This release adds a range of features and bugfixes:

• #342: Add two submodules of combinators in Util:
  • Pp to pretty-print values back to valid OCaml syntax
  • Equal to test equality of values
• #337: Add 3 Bytes.t combinators to Lin: bytes, bytes_small, bytes_small_printable
• #329,340,352: Support qcheck-lin and qcheck-stm on OCaml 4.12.x, 4.13.x and 4.14.x
  without the Domain and Effect modes
• #316: Fix rep_count in STM_thread so that negative and positive
  tests repeat equally many times
• #318: avoid repetitive interleaving searches in STM_domain and STM_thread
• #312: Escape and quote bytes printed with STM's bytes combinator
• #295: ensure cleanup is run in the presence of exceptions in
  • STM_sequential.agree_prop and STM_domain.agree_prop_par
  • Lin_thread.lin_prop and Lin_effect.lin_prop

0.1.1

This is a bug-fix release including the following:

• #263: Cleanup resources after each domain-based Lin test
• #281: Escape and quote strings printed with STM's string combinator

0.1.0

The initial opam release of qcheck-lin, qcheck-stm, and qcheck-multicoretests-util.

The multicoretests package is not released on opam, as it is of limited use to OCaml developers.
