package qcheck-lin

Changes

0.10

• #570: Use dune.3.18 support to generate x-maintenance-intent entries

0.9

• #566: Use QCheck.Print combinators in Util.Pp too for consistency, e.g., to avoid that STM argument and result printer outputs differ.
• #562: Fix the int32 and int64 printers in both Lin and STM to add missing l and L suffixes on literals.
• #560: Change Lin.{constructible,deconstructible} from an empty variant type to an abstract type to get Lin compiling on 5.5.0+trunk again, due to https://github.com/ocaml/ocaml/pull/13994 removing special handling of abstract and empty variants defined in the current module.

0.8

• #540: Significantly increase the probability of context switching in Lin_thread and STM_thread by utilizing Gc.Memprof callbacks. Avoid on 5.0-5.2 without Gc.Memprof support.
• #546: Speed up Lin's default string and bytes shrinkers.
• #547: Add Util.Pp.{cst4,cst5}

0.7

• #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

• No changes to the opam-released library packages. Two significant additions to the test suite in the multicoretests opam package:

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

0.5

• #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

• #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

• #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

• #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

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

0.1

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.
