[Nov.2013 to Mar.2014] mruby news

written by Daniel Bovensiepen on 2014-04-12 22:44 UTC

Due to the sudden allocation of my first born in the beginning of this year this summary comes a little bit later and is much longer than usual. But keep scrolling and investigate the individual commits! The changes in mruby are worth it.

So, what happened with mruby between November 2013 and March 2014?

General

During these five months 625 commits were pushed into the mruby repository (ignoring all merges). 106 of them I identified as Bugfixes, 92 were improvements to the Standard Library, 63 improved the test system, 57 of them were refactoring the code or just small cosmetic changes, 34 made changes to the build system and 11 changed the API.

API

Based on issue #1794 Takeshi Watanabe implemented the new API mrb_proc_new_cfunc_with_env and mrb_cfunc_env_get(mrb_state*, mrb_int) which allows to create a Proc with user data and interact with it.

The 9 month old issue #1269, was also closed by modifying the mruby API. Matz introduced mrb_fiber_yield(mrb_state *mrb, int argc, mrb_value *argv) which allows to create a Fiber from C.

A very small API addition is mrb_context_run(mrb_state *mrb, struct RProc *proc, mrb_value self), which was introduced by Fleurer to handle use-cases like the mirb more elegant.

Standard Library

So many changes were done to the standard library. It is hard to pick the most important ones. In general mruby has stepped a big leap in the direction of being more compatible with CRuby. Lots of missing features were added:

API

Add API to define cfunc Proc with userdata. The APIs are defined in mruby-proc-ext so include it before using this API. See mruby-proc-ext’s test code for usage. This should resolve #1794.

do not use “to_f” to retrieve floats in mrb_get_args(); close #1965

export mrb_yield_internal.

mrb_fiber_yield() is available now; you have to link mruby-fiber mrbgem to use the function; there’s no function available to create new fiber from C (countapart of Lua’s lua_newthread), but that’s because you cannot create a new fiber from C due to mruby C API design limitation. define your method to create fibers in Ruby; close #1269

revert 38e9ce21 and API changed; mrb_get_backtrace() -> renamed to mrb_exc_backtrace since this is a backtrace method implementation of Exception; mrb_get_backtrace_at() -> removed; mrb_get_backtrace() -> added to get backtrace in array (like caller)

avoid copying when the original string comes with MRB_STR_NOFREE

clear STR_NOFREE flag on modify

zero copy str_new from static allocate irep

zero copy intern from static allocate irep

rename mrb_intern_litral -> mrb_intern_static

class/module body to honor whether value is required or not; reduce a few instructions for normal cases

zero copy C literal strings in symbol table

remove MRB_IREP_ARRAY_INIT_SIZE which is no longer used

string type check based on #to_str to encourage duck typing; #1616

verify the argument of String#=~

Remove ‘mrb_state’ field from ‘kh_xxx_t’ structure.

change behavior of mrb_sym2str

remove unnecessary keep size adjustment in stack_extend_alloc(); close #1602

Change scapa and rcapa to size_t, use scapa.

add mrb_intern_lit for creating symbol from string literal

inline mrb_gc_arena_restore() and stack_extend() in VM loop

float objects in pool are objects when MRB_WORD_BOXING is set

move debug record size assertion to correct position

append defines instead of assigning

add CFLAGS as a fallback from CXXFLAGS; ref #1594

remove MRB_PARSER_BUF_SIZE configuration; close #1596

Modify referenced environment variables.

declare struct mrb_irep.

need to free pooled string bodies as well

mrb format should be portable among configurations (e.g. MRB_NAN_BOXING)

irep->pool struct pool -> mrb_value

parser_dump() is not used in mrbc; close #1561

codegen_malloc/realloc: static + simple mem alloc

write_debug_record should dump info recursively; close #1581

check upper callinfo to call ensure block; close #1579

should output debug info for child ireps; close #1575

enum mrb_vtype varies on compile time configuration, namely MRB_NAN_BOXING

remove warning on NAN_BOXING

remove unnecessary jump

Changed a variable declaration to top of block

Changed a variable declaration to top of block

load_exec() no longer return fixnum value for no_exec; should close #1569

fclose input file

call codedump_all() from mirb if –verbose is set; close #1559

check for corrupted mrb file data

protect returning irep (in proc) from GC

allow irep to be GCed

nextc(): always return an ‘\n’ at end of input

type check before pool scan

create Proc object before releasing memory pool

modified to use irep->reps to reference child ireps. preparation for removing irep array from mrb_state. note that instructions OP_LAMBDA, OP_EXEC and OP_EPUSH are incompatible, and dumped mrb format has changed.

mrbc: add line break for -c option

codedump() to take irep structure

change return value from mrb_generate_code()

changed argument type of mrb_ary_modify(); ref #1554
