* Don't mutex-wrap require() more than onceBenoit Germain2014-03-191-1/+1
|
* Fixed crash when using protect_allocator optionBenoit Germain2014-03-171-2/+2
|
* linda:send() improvementsBenoit Germain2014-02-271-6/+2
| | | | | | | | | * Bumped version to 3.9.3 * new exposed variable linda.null that exposes the internal NIL_SENTINEL marker * linda:send() interprets send key linda.null as authorization to silently send a single nil when not provided with anything to send (useful when sending results of a function that can return nothing)
* Multiverse compatibilityBenoit Germain2014-02-261-69/+89
| | | | | | | | | | | | | | | * bumped version to 3.9.2 * Internal rework: the whole Lanes engine now works "per universe" to allow concurrent Lanes execution in more than one embedded master state * this universe is a full userdata created in the master state, selfdestruct_gc is the __gc for this userdata * most of what was initialized only once is now per-universe * Fixed potential crashes at desinit if problems occur during keeper states initialisation * Fixed require() not always serialized properly * Raise an error instead of crashing on deep userdata prelude memory allocation failure * Added forgotten mutex desinitialisation at universe shutdown
* Lanes init crash fixBenoit Germain2014-02-181-25/+42
| | | | | | | | | | | * bumped version to 3.9.1 * keeper array is allocated with master state's alloc function instead of malloc()/free() * prevent application crash when specifying a very large number of keepers in the configuration options * removed some keeper desinit legacy dead code * any error occuring during one-time inits is raised outside the one-time mutex protected code region
* lindas can have a group for keeper state assignation controlBenoit Germain2014-02-171-4/+4

* Deep userdata support improvementsBenoit Germain2014-02-171-11/+33
| | | | | | | | | | | | * bumped version to 3.9.0 * keepers now require "package", receive package.path & package.cpath, and call on_state_create() if it is a C function * changed the deep public API (improved deep idfunc signature, renamed luaG_deep_userdata to luaG_newdeepuserdata) * if an error occurs while copying a deep userdata, don't raise inside the keeper state * fixed situations where raised errors could lead to memory leaks (deep gc)
* more fixes/tweaks about cancelled lindasBenoit Germain2014-02-131-0/+2
| | | | | | | | | | * bumped version to 3.8.5 * linda:limit() returns lanes.cancel_error on a limited linda * lanes.genlock() and lanes.genatomic() support cancelled lindas by returning lanes.cancel_error whenever appropriate * fixed a possible Lua stack overflow when calling linda:dump() * fixed cases where linda:send() and linda:receive() would not return lanes.cancel_error when they should
* linda performance improvementBenoit Germain2014-01-201-5/+9
| | | | | slightly improve linda performance when the producer/consumer scenario leaves leave the key empty
* get()/set() improvementsBenoit Germain2014-01-201-48/+54
| | | | | | | * bumped version to 3.8.0 * linda:set() accepts multiple values to set in the specified slot * linda:get() accepts an optional count to peek several values at once * nil values are now converted just as in send()/receive()
* Linda fixesBenoit Germain2014-01-091-29/+67
| | | | | | | | | | | * bumped version to 3.7.7 * fix crash when calling linda:count() on unknown keys * purge key storage with linda:set( key, nil) on an unlimited key to reduce memory usage with lots of keys * linda:limit() wakes write-blocked threads if necessary when the new limit enables writes to occur again * linda:set() wakes write-blocked threads if necessary if the operation created some room to write into
* fixed a shutdown crashBenoit Germain2013-12-201-6/+10
| | | | | | | * fixed a crash that can occur at shutdown when an object stored inside a keeper state performs a linda operation on a linda making use of another keeper * bumped version to 3.7.5
* supposedly improved pthread supportBenoit Germain2013-11-291-5/+4
| | | | | | | | | * bumped version to 3.7.3 * set pthread thread cancel type to PTHREAD_CANCEL_ASYNCHRONOUS * lane_h:cancel() accepts a 3rd timeout argument used when waiting for actual thread termination (hitting the timeout raises an error) * added PROPAGATE_ALLOCF macro to select state creation mode (lua_newstate or luaL_newstate)
* Fix a 64 bits compilation warningBenoit Germain2013-11-261-1/+1

|
* version 3.7.0Benoit Germain2013-10-111-16/+30
| | | | | | | | | | | | * fix lanes.threads() not being available in a lane where lanes.configure() settings didn't contain track_lanes although the initial configure() call did. * require "lanes".configure() sequence is only necessary at the first require "lanes". * fix a crash at application shutdown where in some situations we could deinitialize the protected allocator mutex while a lane was still using it. * fix timers broken by change 69
* version 3.6.6Benoit Germain2013-09-271-2/+0
| | | | | | | | no longer call core.configure with dummy params when requiring lanes more than once (fixes potential multithreading issues with LuaJIT allocator) activated EnableCrashingOnCrashes() Win32 debug builds fixed some comments in code
* Reduce memory footprint, simplify module order setup in conjuction with ↵Benoit Germain2013-09-261-71/+7
| | | | | | | | | | | | Lanes, and send over native functions a bit faster as well * Lanes no longer has to internally require modules inside the keeper states because they no longer need a lookup database. the lookup name is stored as-is and actually converted in the destination state * optimisation: bypass cache when sending native functions over * removed all the KEEPER_MODEL_LUA code, as it can no longer work anyway
* Fix bad assertion in linda dump utilityBenoit Germain2013-02-141-2/+8

* version 3.5.1v3.5.1Benoit Germain2013-02-131-1/+1
| | | | | | | * new lanes.h header and API call luaopen_lanes_embedded() for embedders * "lanes.core" is an acceptable library in the generator libs argument * library "*" wildcard also opens lanes.core * tweaked code for Xbox 360 build
* version 3.5.0Benoit Germain2013-01-301-6/+9
| | | | | | | | | | | | | | * 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
* * More detailed DEBUG_SPEW logsBenoit Germain2013-01-281-19/+24
| | | | * A bit of code cosmetics
* version 3.4.4v3.4.4Benoit Germain2013-01-261-3/+1
| | | | | | | | * bugfix: take into account the fact that "coroutine" is no longer part of base library in Lua 5.2 * bugfix: if "bit32" was listed in the libraries, it wouldn't open (library list parsing failing on digits) * bugfix: Use luaL_requiref() to open standard libraries in Lua 5.2 as we should * bugfix: any Lua state created by Lanes reuses the allocator function of the originating state * bugfix: don't call on_state_create() while GC is suspended during lua state initialization
* version 3.4.3v3.4.3Benoit Germain2013-01-241-34/+23
| | | | | | | | | | | * raise an error if lane generator libs specification contains a lib more than once * bit32 is a valid lib name in the libs specification (silently ignored by the Lua 5.1 build) * improved lanes.nameof to search inside table- and userdata- metatables for an object's name * fixed an unwarranted error when trying to discover a function name upon a failed transfer * contents of package.[path,cpath,preload,loaders|searchers] are pulled *only once* inside keeper states at initialisation * Lua function upvalues equal to the global environment aren't copied by value, but bound to the destination's global environment especially useful for Lua 5.2 _ENV * fixed loading of base libraries that didn't create the global tables when built for Lua 5.2

* Yet another shutdown crash fixbenoit-germain2012-08-101-0/+4
| | | | Perform keeper desinit in two stages, in case the keeper state being closed contains a reference to a linda bound to a previously desinitialized keeper, causing it to be destroyed after its keeper state. (occurs only for applications using more than one keeper).
