Sami Vaarala	fef0870107	First round of lightfunc changes A lot of changes to add preliminary lightfunc support: * Add LIGHTFUNC tagged type to duk_tval.h and API. * Internal changes for preliminary to support lightfuncs in call handling and other operations (FIXMEs left in obvious places where support is still missing after this commit) * Preliminary Ecmascript and API testcases for lightfuncs Detailed notes: * Because magic is signed, reading it back involves sign extension which is quite verbose to do in C. Use macros for reading the magic value and other bit fields encoded in the flags. * Function.prototype.bind(): the 'length' property of a bound function now comes out wrong. We could simply look up the virtual 'length' property even if h_target is NULL: no extra code and binding is relatively rare in hot paths. Rewrite more cleanly in any case. * The use flag DUK_USE_LIGHTFUNC_BUILTINS controls the forced lightfunc conversion of built-ins. This results in non-compliant built-ins but significant memory savings in very memory poor environments. * Reject eval(), Thread.yield/resume as lightfuncs. These functions have current assertions that they must be called as fully fledged functions. * Lightfuncs are serialized like ordinary functions for JSON, JX, and JC by this diff. * Add 'magic' to activation for lightfuncs. It will be needed for lightweight functions: we don't have the duk_tval related to the lightfunc, so we must copy the magic value to the activation when a call is made. * When lightfuncs are used as property lookup base values, continue property lookup from the Function.prototype object. This is necessary to allow e.g. ``func.call()`` and ``func.apply()`` to be used. * Call handling had to be reworked for lightfuncs, especially how bound function chains are handled. This is a relatively large change but is necessary to support lightweight functions properly in bound function resolution. The current solution is not ideal. The bytecode executor will first try an ecma-to-ecma call setup which resolves the bound function chain first. If the final, unbound function is not viable (a native function) the call setup returns with an error code. The caller will then perform a normal call. Although bound function resolution has already been done, the normal call handling code will re-do it (and detect there is nothing to do). This situation could be avoided by decoupling bound function handling and effective this binding computation from the actual call setup. The caller could then to do this prestep first, and only then decide whether to use an ecma-to-ecma call or an ordinary heavyweight call. Remove duk__find_nonbound_function as unused. * Use indirect magic to allow LIGHTFUNCs for Date. Most of the built-in functions not directly eligible as lightfuncs are the Date built-in methods, whose magic values contain too much information to fit into the 8-bit magic of a LIGHTFUNC value. To work around this, add an array (duk__date_magics[]) containing the actual control flags needed by the built-ins, and make the Date built-in magic value an index into this table. With this change Date built-ins are successfully converted to lightfuncs. Testcase fixes: - Whitespace fixes - Print error for indirect eval error to make diagnosis easier - Fix error string to match errmsg updated in this branch	11 years ago

Sami Vaarala	4cbf7cd1dd	massif-XXX targets for heap use Print out the massif graph and a grepped "maximum usage" to get some quick idea of how much memory a certain ecmascript testcase uses at the moment. Used for e.g. a hello world memory usage test. Usage is: "make massif-test-dev-hello-world" or "make massif-XXX" for any other test in ecmascript-testcases/. A few convenience targets like massif-helloworld are included. Set --peak-inaccuracy=0.0 for massif run to get as accurate a peak estimate as possible. (This is not that important because the measure itself is not 100% relevant.) Also adds a testcase needed by massif-helloworld target.	10 years ago
Sami Vaarala	25b6a0bc29	Merge branch 'cmdline-ajpool' Add a test "ajduk" command which integrates AllJoyn.js pool allocator, which is quite useful for low memory testing. When compiling for x86, the "ajduk" command memory usage will behave quite closely compared to a typical embedded ARM-based system. The "ajduk" command dumps the AllJoyn.js pool state in specific places (after heap creation, right before destroying, etc) for comparison. There is also a global binding "AjsHeap.dump()" which can be used to explicitly dump the heap state from Ecmascript code.	10 years ago
Sami Vaarala	077f061f09	Add AllJoyn.js AjsHeap support to duk_cmdline AllJoyn.js has a pool allocator which serves as a good example for using Duktape with a pool allocator in a low memory environment.	10 years ago

Sami Vaarala	99807ae89b	Merge branch 'make-func-name-writable' Make Function.prototype.name writable so that user code can set a "name" property for Duktape/C functions. Duktape/C functions don't have a "name" property by default and a non-writable ancestor prevents creating one. Fixes GH-79.	10 years ago

Sami Vaarala	cd429f062d	Merge branch 'add-hybrid-alloc-example' Add a hybrid pool allocator example to the distibution. The allocator uses a fixed set of pools for small allocations but falls back to malloc etc for larger sizes and when the pools are exhausted. This reduces churn on the platform memory allocator which is beneficial for platforms where the platform allocator is not tuned for a lot of small allocations.	10 years ago

Sami Vaarala	5b7ef1f5fb	Merge branch 'api-get-heapptr' Add API calls duk_get_heapptr() and duk_require_heapptr() to get a borrowed void pointer reference to Duktape heap allocated values (objects, strings, and buffers). Add API call duk_push_heapptr() to recreate an object reference based on a borrowed pointer later. However, the original value must have been reachable all the way to this call, so it still needs to be stashed as before.	10 years ago
