* Fix broken timersBenoit Germain2013-10-041-0/+1

* version 3.5.0Benoit Germain2013-01-301-160/+163
| | | | | | | | | | | | | | * new: API lanes.require(), use it instead of regular require() for modules that export C functions you need to send over. * new: lanes no longer require 'lanes.core' by default in every created state. Use {required={"lanes.core"}} if you need to transfer lanes functions. * internal: because of the above, reworked the timer implementation to remove upvalue-dependency on lanes.core * new: API lanes.timer_lane, to be able to operate on timer lane if need be * improved: if a module is a full userdata, scan its metatable for function database population * improved: on_state_create can be a Lua function * changed: on_state_create is called after the base libraries are loaded * package[loaders|searchers] is no longer transfered as function naming depends on slot order * internal: changed separator from '.' to '/' in lookup databases to be able to distinguish search levels and dot coming from module names * added some mode debug spew * updated tests to reflect the above changes

* version 3.4.0Benoit Germain2012-09-261-2/+2
| | | | | | | | | | * new method linda:dump() that outputs the full contents of a linda as a table, also linked to __towatch for Decoda support * linda:receive() API change! * instead of [val, key], linda:receive( timeout, key) returns [key, val] * instead of [val, [...]], linda:receive( timeout, linda.batched key) returns [key, val[, ...]] this is to unify the return values of regular and batched mode, and to be able to tell when batched mode is interrupted by a lane cancellation * fixed Lua 5.2 build to take into account the "loaders"->"searchers" name change in 'package' module. * a bit of html cleanup and added some infos in the documentation regarding the Lanes internals
* version 3.3.0Benoit Germain2012-09-101-55/+87
| | | | | | | | | | | | * lane.status can return "killed" if lane was forcefully killed with lanes:cancel() * lane:join(): return nil, "killed" if called on a killed lane. * lane[<n>]: produces [1] = nil, [2] = "killed" if the lane was killed * lane:join(): fixed an assertion in debug builds when joining a lane forcefully cancelled with lane:cancel( <x>, true). * indexing a lane with a string other than "join", "cancel" or "status" raises an error. * fixed configure() to correctly apply defaults when they are missing from the provided settings * added a shutdown_timeout to control the duration Lanes will wait for graceful termination of running lanes at application shutdown. Default is 0.25. Among other things, fixes issue #31.

| | | | | | | | | | | | | | | | | | | | when atexit() handlers are processed * Lua 5.2-style module: * module() is no longer used to implement lanes.lua * a global "lanes" variable is no longer created when the module is required * the Lanes module table is returned instead * Lanes must be initialized before used: * the first occurence of 'require "lanes"' produces a minimal interface that only contains a configure() function * the remainder of the interface is made available once this function is called * subsequent calls to configure() do nothing * configure() controls the number of keeper states and the startup of timers * LuaJIT 2 compatibility * non-Lua functions are no longer copied by creating a C closure from a C pointer, but through 2-way lookup tables * this means that if a lane function body pulls non-Lua functions, the lane generator description must contain the list of libraries and modules that exports them * introduces a change in configuration .globals management: contents are copied *after* std libs are loaded * new .required configuration entry to list modules that must be require()'ed before lane body is transferred * lane:cancel() wakes up waiting lindas like what is done at lane shutdown
