2.4.2
* fix the stub for Lwt_unix.readdir
* change the default method for Lwt_glib.install (use the glib main loop by
default: more portable)
* ignore invalid file descriptors returned by glib (like the emulation of
select in glib does)
* use environment variables in discover.ml - use LIBRARY_PATH and
C_INCLUDE_PATH for searching headers - allow to pass flags for a library
in <LIB>_CLFAGS and <LIB>_LIBS
* add Lwt_unix.on_signal_full
2.4.1
* Add Lwt_stream.on_terminate
* Fix Lwt_gc
* Fix stubs for get_credentials on *BSD
This is a maintainer update of devel/ocaml-lwt to its newest version, 2.4.0. The
changelog (bugfixes and some enhancements, plus compatibility with ocaml 4.00,
though it should still compile with ocaml 3.12):
- Reimplement Lwt_stream
much simpler and more efficient
do not use Weak
add bounded push streams
- Add Lwt.async
- Add Lwt_preemptive.run_in_main
- Implement Lwt_unix.get_credentials on MacOS X/OpenBSD
- Ensure that on_cancel functions are executed first
- Better implementation of Lwt.cancel with more tests
- Simplify the API for unix jobs
- Better handling of the master lock in libev stubs
- Windows fixes/updates:
pass -lws2_32 instead of ws2_32.lib if building with mingw
fix a bug causing Lwt_unix.read/write to block when a socket is not
readable/writable
port Lwt_process and Lwt_unix.system to windows
- Compatibility with ocaml 4.00:
add O_SHARE_DELETE to Lwt_unix.open_flag
add -package compiler-libs.toplevel for files using Toploop
- Do not use module Sys for signal handling to avoid ocaml code to be called in a C thread
- Fix Lwt_unix.wrap_syscall: try instead of Lwt.catch
- Fix a dead-lock between lwt_unix_send_notificati
- Fix#277: add a function to return the Ssl.socket of a Lwt_ssl.socket
There have also been a few changes to the package itself; it now uses
PLIST_VARS, and the patches are replaced by the SUBST mechanism.
