* 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

Fix lookup database table not being created when it should if Lanes is
required in more than one Lua master state

* raise an error instead of dereferencing a NULL pointer on deep
userdata creation and lane struct creation

* 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

* 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)

* 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

* bumped version to 3.8.4
* all linda operations return lanes.cancel_error on a cancelled linda
* raised an internal string length so that longer linda names are fully
output before truncation applies when doing tostring( linda)

* bumped version to 3.8.3
* fixed a possible Lua stack overflow when sending complex function
through lindas or as lane body
* experimental: lanes.nameof() scans the registry if a regular search
didn't yield anything interesting
* fixed lanes.nameof() misbehaving when encountering a LUA_TTHREAD
object

* bumped version to 3.8.2
* new lane launcher option gc_cb to set a callback that is invoked when
a lane is garbage collected
* Fix more invalid memory accesses when fetching the name of a joined
lane with lanes:threads() (because its lua_State is closed)

slightly improve linda performance when the producer/consumer scenario
leaves leave the key empty

* bump version to 3.8.1
* new function lane:get_debug_threadname()
* Fix invalid memory accesses when fetching the name of a joined lane
with lanes:threads() (because its lua_State is closed)
* use luaL_newmetatable() to create the metatable for lane objects
* prevent malicious code from crashing by calling lane methods without
passing the lane as first argument (raise an error instead)
* set_debug_threadname() is no longer registered in the function lookup
databases because it holds a C pointer as upvalue and it might crash if
used maliciously

* bumped version to 3.8.0
* linda:set() accepts multiple values to set in the specified slot

* bumped version to 3.7.8
* lane:cancel() now accepts a boolean second argument when soft
cancelling (negative timeout) to wake the thread if necessary
* if a blocked linda send() or receive() call is interrupted by a
cancellation request, it returns CANCEL_ERROR so that this case can be
differentiated from a simple timeout
* fixed WIN32 THREAD_CREATE() wrong _beginthreadex() error detection
* fatal WIN32 threading errors retrieve and output the error description
string with FormatMessage()
* fixed missing lanes.set_singlethreaded
* fixed perftest.lua
* added test/cancel.lua

* 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

* if config.on_state_create() is a C function, call it by direct C
closure reconstruction in newly created states
* bumped version to 3.7.6

* 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 3.7.3
* 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 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

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

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

* lane:cancel(<negative-timeout>) only causes cancel_test() to return
true but won't interrupt execution of the lane during linda operations
* more explicit errors when trying to transfer unknown source functions
(with new configure option verbose_errors)
* default options wrap allocator around a mutex when run by LuaJIT
|
| | |
|
| |
|
|
|
| |
* WIN32 builds use condition variables instead of PulseEvent() when available.
* first steps toward fixing make-vc.cmd

| |
* protect_allocator is an API change -> version bump
* bugfix: allocator protection should be done once per primary Lua state, not once only the first time ever Lanes is required
|
| |
|
|
|
|
| |
* stricter validation of with_timers config option: validator was accepting any non-boolean value
* new configuration option protect_allocator for VMs with thread unsafe allocators (such as LuaJIT)
* removed some obsolete bits of dead code
|
| |
|
|
|
|
|
| |
* 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

* 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
|
| |
|
|
| |
* A bit of code cosmetics

* 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

* 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
