1.2.3

CHANGES:

• Update to cmdliner 1.1.0 (@MisterDA #249).

• Fix tests on Windows, avoid using Unix domain sockets (@talex5 #251).

• Fix warning on Unix.ENOTCONN under macos (@talex5 #252).

• Add Capnp_rpc_unix.Cap_file.save_uri (@talex5 #253).

• Update README to use MDX (@talex5 #254).

• Update tests to Cap'n Proto 0.10.3 (@MisterDA #257 #260).

• Update to mirage-crypto-rng 0.11 and dns 7.0.0 API changes (@hannesm #261).

• Update for opam 2.1+ installations (@frumioj #259).

• Install Cap'n Proto binaries in Windows GHA (@MisterDA #248).

1.2.2

CHANGES:

• Switch from mirage-{stack,protocols} to tcpip (@MisterDA #246).

• Remove deprecated tcpip.unix dependency (@hannesm #245).

• Add OCaml 4.14 support (@kit-ty-kate #244).

1.2.1

CHANGES:

• Fix Fmt deprecation warnings (@tmcgilchrist #239).

• Update to latest X509 and DNS APIs (@tmcgilchrist #240).

v1.2

CHANGES:

• Don't crash if the peer disconnects before the bootstrap reply is ready (@talex5 #234).
  When replying to a normal question we checked that the answer was still needed before trying to reply, but didn't for bootstrap requests.

• Replace wait_until_settled with safer await_settled (@talex5 #233).
  wait_until_settled makes it too easy to ignore errors.

• Require fmt >= 0.8.7 for kstr and set OCaml 4.08 as the minimum version everywhere (@talex5 #232).
  Older versions aren't tested in CI because the unix and mirage packages require at least OCaml 4.08.

v1.1

CHANGES:

• Update to latest X509, TCP and TLS APIs (@talex5 @hannesm #228).

• Add Service.fail_lwt convenience function (@talex5 #229).

• Remove confusing debug details from call_for_value_exn errors (@talex5 #230).
  The hidden information is now logged (at debug level) instead.

• Configure TCP keep-alives for incoming connections, not just outgoing ones (@talex5 #227).
  This is needed when the client machine crashes without resetting the connection.

• Include version number in opam license field (@talex5 #226).

v1.0

CHANGES:

• Skip the setting of object_id if it is empty (@LasseBlaauwbroek #224).
  This improves interoperability with the C++ implementation.

• Use open_in_bin instead of open_in for Windows compatibility (@MisterDA #222).

v0.9.0

CHANGES:

• Add connection progress indicator (@talex5 #220).
  Clients can now use Capnp_rpc_unix.with_cap_exn to show a progress indicator while waiting to connect.
  It will use the log if enabled.
  If not, but stderr is a tty, it shows a message while connecting and then erases it (if connecting takes longer than 0.5s).
  If stderr is not a tty, it just prints a message there.

• Use Mirage_crypto_rng_lwt.initialize instead of Mirage_crypto_rng_unix.initialize (@hannesm #217).
  The former periodically feeds entropy to the RNG, while the latter seeds the RNG only once.

• Set TCP_KEEPIDLE=60 if possible (@talex5 #214).
  Cap'n Proto connections tend to be long lived and we therefore turn on the SO_KEEPALIVE option.
  However, the default keepalive timeout of 2 hours is much too long for some networks.
  In particular, Docker's libnetwork silently drops idle connections after about 10 minutes.

Windows support:

• Prevent crash if ExtUnix wasn't built with sockopt (@MisterDA #218).
  If ExtUnix isn't built with sockopt then the symbol have_sockopt_int isn't available and an exception is raised.
  This may be the case on some environments (e.g., ExtUnix built with mingw-w64).
  It is a workaround until support for TCP_KEEPIDLE is added for these environments (e.g., using Winsock instead).

• There is no SIGPIPE on Windows (@dra27 #212).

• Switch from "capnpc" to "capnp compile" (@talex5 #213).
  capnpc seems to be the old name, and isn't present on Windows.

Build changes:

• Remove Travis and Dockerfile (@talex5 #220).
  Travis is very slow and error-prone now, and ocaml-ci generates a working Dockerfile automatically for people who want it.

• Include transitive dependencies in opam files (@talex5 #219).
  Patch generated by https://github.com/ocurrent/opam-dune-lint/

• Require tcpip.unix specifically to get the checksum stubs linked (@hannesm #216).

v0.8.0

CHANGES:

Bug fixes and diagnostics:

• Don't GC imports with callbacks (@talex5, #210).

• Improve "Already resolved!" error message (@talex5, #209).
  Show the state of the promise we were trying to set, and what we tried to set it to.

• Reject attempts to send after disconnecting (@talex5, #208).

• Unix: don't leak FDs if Network.connect fails (@talex5, #206).
  Also, use Lwt to open connections so we don't block the whole process.

New functions:

• Add Sturdy_ref.with_cap and with_cap_exn convenience functions (@talex5, #207).
  Using the plain connect functions, it's easy to forget to release the live-ref at the end.

Build changes:

• capnp-rpc-mirage: adapt test to tcpip 5.0.0 API (@hannesm, #205).

• Upgrade to dune 2 (@talex5, #204).

• Switch tests to build in native code and use the test stanza (@avsm, #203).

Documentation:

• Show how to make a connection directly (@talex5, #202).
  The new test-bin/calc_direct.ml example shows how a parent process can
  spawn a child and communicate with it directly over a socketpair.

v0.7.0

CHANGES:

• Update for x509 0.11.0 API changes (@talex5, #196).

• Update to new mirage network API (@Cjen1, #198).

• Add echo benchmark test (@Cjen1, #197).

• Estimate message sizes to improve performance (@talex5, #200).
  By default, capnproto allocates 8k buffers, but most capnp-rpc messages are
  much smaller than this.

Logging:

• Fix application logging, to use library's log (@Cjen1, #195).

• Expose the endpoint logger (@Cjen1, #195).

• Only enable debug logging for capnp libraries in the calc example.
  TLS now generates a lot of messages at debug level (@talex5, #200).

v0.6.0

CHANGES:

• Port to latest interfaces for x509 (0.10+), mirage-crypto,
  alcotest (1.0+), and mirage-types post the -lwt package
  merge (@avsm #190, review by @talex5 @hannesm)

• Convert many info-level log messages to debug level (@talex5 #193)
