<li>orphaned threads will not be collected unless garbage collection is run and sufficient time elapses
|

</ul>
|
||||
<h3>Garbage Collection And Resources</h3>
|
||||
LuaJ does not implement the same garbage collector semantics as native Lua. Garbage collection is delegated to the host JVM or CLDC runtime, so <code>collectgarbage()</code> is only a hint and should not be used as a resource-management primitive.
|
||||
<p>
|
||||
In particular:
|
||||
<ul>
|
||||
<li>Do not rely on garbage collection to close files, sockets, database handles, or other resources.
|
||||
<li>Always call <code>close()</code> explicitly on files and iterators that own files.
|
||||
<li><code>io.lines(filename)</code> opens a file implicitly. If iteration is abandoned early, that file may remain open until explicitly collected by the host runtime.
|
||||
<li>Prefer <code>local f = assert(io.open(...))</code> together with <code>f:lines()</code> and an explicit <code>f:close()</code> when deterministic cleanup matters.
|
||||
<li>For implicit line iterators that need deterministic early cleanup, use <code>io.linesx(filename)</code> and call <code>iterator:close()</code>.
|
||||
<li><code>file:linesx()</code> provides the same closable iterator API for already-open files.
|
||||
<li>On Windows, leaked file handles can prevent rename or delete operations until the process exits.
|
||||
<li>On JME/CLDC, finalization support may be absent, so explicit close is mandatory.
|
||||
</ul>
|
||||
<p>
|
||||
Short-lived locals may also remain reachable longer than expected because host stack/register reuse is implementation-dependent. If prompt reclamation matters, isolate temporary allocations in functions and clear large references explicitly instead of assuming block exit is enough.
|
||||
<h3>File Character Encoding</h3>
|
||||
Source files can be considered encoded in UTF-8 or ISO-8859-1 and results should be as expected,
|
||||
with literal string contianing quoted characters compiling to the same byte sequences as the input.

|

We assume that instructions are unsigned numbers.
|
||||
All instructions have an opcode in the first 6 bits.
|
||||
Instructions can have the following fields:
|
||||
`A' : 8 bits
|
||||
`B' : 9 bits
|
||||
`C' : 9 bits
|
||||
`Bx' : 18 bits (`B' and `C' together)
|
||||
`sBx' : signed Bx
|
||||
|
||||
A signed argument is represented in excess K; that is, the number
|
||||
value is the unsigned value minus K. K is exactly the maximum value
|
||||
for that argument (so that -max is represented by 0, and +max is
|
||||
represented by 2*max), which is half the maximum for the corresponding
|
||||
unsigned argument.

Notes:
|
||||
(*) In OP_CALL, if (B == 0) then B = top. C is the number of returns - 1,
|
||||
and can be 0: OP_CALL then sets `top' to last_result+1, so
|
||||
next open instruction (OP_CALL, OP_RETURN, OP_SETLIST) may use `top'.
|
||||
|
||||
(*) In OP_VARARG, if (B == 0) then use actual number of varargs and
|
||||
set top (like in OP_CALL with C == 0).
|
||||
|
||||
(*) In OP_RETURN, if (B == 0) then return up to `top'
|
||||
|
||||
(*) In OP_SETLIST, if (B == 0) then B = `top';
|
||||
if (C == 0) then next `instruction' is real C
|
||||
|
||||
(*) For comparisons, A specifies what condition the test should accept
|
||||
(true or false).
|
||||
|
||||
(*) All `skips' (pc++) assume that next instruction is a jump

/**
|
||||
* Extension of {@link LuaFunction} which executes lua bytecode.
|
||||
* <p>
|
||||
* A {@link LuaClosure} is a combination of a {@link Prototype}
|
||||
* and a {@link LuaValue} to use as an environment for execution.
|
||||
* Normally the {@link LuaValue} is a {@link Globals} in which case the environment
|
||||
* will contain standard lua libraries.
|
||||
*
|
||||
* <p>
|
||||
* There are three main ways {@link LuaClosure} instances are created:
|
||||
* <ul>
|
||||
* <li>Construct an instance using {@link #LuaClosure(Prototype, LuaValue)}</li>
|
||||
* <li>Construct it indirectly by loading a chunk via {@link Globals#load(java.io.Reader, String)}
|
||||
* <li>Execute the lua bytecode {@link Lua#OP_CLOSURE} as part of bytecode processing
|
||||
* </ul>
|
||||
* <p>
|
||||
* To construct it directly, the {@link Prototype} is typically created via a compiler such as
|
||||
* {@link org.luaj.vm2.compiler.LuaC}:
|
||||
* <pre> {@code
|
||||
* String script = "print( 'hello, world' )";
|
||||
* InputStream is = new ByteArrayInputStream(script.getBytes());
|
||||
* Prototype p = LuaC.instance.compile(is, "script");
|
||||
* LuaValue globals = JsePlatform.standardGlobals();
|
||||
* LuaClosure f = new LuaClosure(p, globals);
|
||||
* f.call();
|
||||
* }</pre>
|
||||
* <p>
|
||||
* To construct it indirectly, the {@link Globals#load(java.io.Reader, String)} method may be used:
|
||||
* <pre> {@code
|
||||
* Globals globals = JsePlatform.standardGlobals();
|
||||
* LuaFunction f = globals.load(new StringReader(script), "script");
|
||||
* LuaClosure c = f.checkclosure(); // This may fail if LuaJC is installed.
|
||||
* c.call();
|
||||
* }</pre>
|
||||
* <p>
|
||||
* In this example, the "checkclosure()" may fail if direct lua-to-java-bytecode
|
||||
* compiling using LuaJC is installed, because no LuaClosure is created in that case
|
||||
* and the value returned is a {@link LuaFunction} but not a {@link LuaClosure}.
|
||||
* <p>
|
||||
* Since a {@link LuaClosure} is a {@link LuaFunction} which is a {@link LuaValue},
|
||||
* all the value operations can be used directly such as:
|
||||
* <ul>
|
||||
* <li>{@link LuaValue#call()}</li>
|
||||
* <li>{@link LuaValue#call(LuaValue)}</li>
|
||||

* <li>{@link LuaValue#method(String)}</li>

/**
|
||||
* Subclass of {@link LuaValue} that implements
|
||||
* a lua coroutine thread using Java Threads.
|
||||
* <p>
|
||||
* A LuaThread is typically created in response to a scripted call to
|
||||
* {@code coroutine.create()}
|
||||
* <p>
|
||||
* The threads must be initialized with the globals, so that
|
||||
* the global environment may be passed along according to rules of lua.
|
||||
* This is done via the constructor arguments {@link #LuaThread(Globals)} or
|
||||
* {@link #LuaThread(Globals, LuaValue)}.
|
||||
* <p>
|
||||
* The utility classes {@link org.luaj.vm2.libs.jse.JsePlatform} and
|
||||
* {@link org.luaj.vm2.libs.jme.JmePlatform}
|
||||
* see to it that this {@link Globals} are initialized properly.
|
||||
* <p>
|
||||
* The behavior of coroutine threads matches closely the behavior
|
||||
* of C coroutine library. However, because of the use of Java threads
|
||||
* to manage call state, it is possible to yield from anywhere in luaj.
|
||||
* <p>
|
||||
* Each Java thread wakes up at regular intervals and checks a weak reference
|
||||
* to determine if it can ever be resumed. If not, it throws
|
||||
* {@link OrphanedThread} which is an {@link java.lang.Error}.
|
||||
* Applications should not catch {@link OrphanedThread}, because it can break
|
||||
* the thread safety of luaj. The value controlling the polling interval
|
||||
* is {@link #thread_orphan_check_interval} and may be set by the user.
|
||||
* <p>
|
||||
* There are two main ways to abandon a coroutine. The first is to call
|
||||
* {@code yield()} from lua, or equivalently {@link Globals#yield(Varargs)},
|
||||
* and arrange to have it never resumed possibly by values passed to yield.
|
||||
* The second is to throw {@link OrphanedThread}, which should put the thread
|
||||
* in a dead state. In either case all references to the thread must be
|
||||
* dropped, and the garbage collector must run for the thread to be
|
||||
* garbage collected.
