I am not sure whether I understand your statement. mrbc is built using the core, core using symbols generated from presym. If we update the presym we need to compile everything again.
If we use mrbc to generate presym, the build steps would be:
- build core without
presym - build
mrbcusing the first core - generate binary files and
presymusingmrbc - recompile everything again (this time including gems)
It is redundant. I have several ideas to avoid recompilation, but it requires a big rewrite regarding mrbc.

To avoid repeated compilation, presym' need to be generated beforemrbc`. That is the biggest constraint.
If you have any idea, let me know.

Prohibit string changes by "s"/"z" specifier of `mrb_get_args()` - The `s` specifier is a string pointer obtained without performing `mrb_str_modify()`, so it cannot be changed. - The `z` specifier cannot be changed because it is a string pointer obtained by `RSTRING_CSTR()` which returns `const char *`.

I modified the line that caused the problem. It could be my fault. Sorry if it's the case.

Introduce malloc_trim on linux to fix dirty page leak
To begin please understand that mruby is not doing anything incorrectly. There is no issue with the way mruby allocates and releases memory and does not have a memory leak. This is a discussion on using the glibc malloc/realloc/free as default will not return dirty allocated pages back to the kernel managed heap automatically. This issue exists on any dynamic language using glib allocator.
Summary
- The glib allocator doesn't return dirty pages back to the OS heap automatically until the program allocations meet rare conditions
- Calling glib specific
malloc_trimforces glib allocator to return dirty heap pages - I propose adding a call to
malloc_trimon a major GC and as a final step inmrb_close - Asking for advice on the lowest impact way of adding this code
Research
Following up on @FooBarWidget absolutely wonderful research about the glibc allocator I wanted to test the same with mruby. The short summary from his research is by default glibc free does not automatically mark free pages as unused with madvise without hitting a frankly absurd page usage threshold.
This is not a new discovery. It is obscure though discussed elsewhere through the years, and on C Ruby
- https://stackoverflow.com/a/47061458
- https://stackoverflow.com/a/3860495
- https://bugs.ruby-lang.org/issues/15667
We can force marking the free pages by calling the glib specific malloc_trim. The results I observed with mruby are the same as presented with C Ruby, which is not a surprise.
Here is what I used for a test program along with a Rake file for automation. First, I built libmruby.a from master using defaults, and then libmruby-gcpatched.a using this patch. It calls malloc_trim on a major GC cycle

It finds the base address of glibc and then finds the base address of the shared glibc within the current program and uses it as the base address of the memory heap. Then, after creating a new mrb_state, creates 10,000 empty Fiber objects within the VM, partitioned into four global arrays. Then remove the second and fourth arrays and forcing garbage collection. After, code takes two paths. One is entirely default behavior with no changes from mruby master and then dumps the heap layout. The second when passed a trim parameter. When passed trim it calls malloc_trim(0) before dumping the heap layout. This gives us an indication on how mruby behaves and whether calling malloc_trim helps here.
The visualization divides the OS heap pages used by the program. Red dots are usage within the heap page. Grey dots are usage within the heap page marked as 'free, dirty' and not yet reclaimed by the kernel. White is previously allocated dirty pages marked as unused to the kernel.
This is the result of default behavior on a standard Ubuntu 18.04 system
The result of calling malloc_trim before dumping the heap.
And finally, default behavior with the patch, which calls malloc_trim after every major GC cycle.
We can also observe this by looking at heap memory usage as reported by the kernel. We can see that the defaults consume 19MB of heap memory reported by the kernel, while calling malloc_trim consumes 10mb of memory reported.
Since all of the VM is encapsulated in mrb_state we can go further with our research than observing C Ruby's global VM state. Moving the call to mrb_close in the above program to right after the mrb_load_string call we see some major results, like this
mrb_load_string(mrb, "$a = []; $b = []; $c = []; $d = []; 2_500.times { $a.push(Fiber.new {}) }; 2_500.times { $b.push(Fiber.new {})}; 2_500.times { $c.push(Fiber.new {})}; 2_500.times { $d.push(Fiber.new {})}; $b = nil; $d = nil; GC.start;");
mrb_close(mrb);
Calling mrb_close on the default path
Calling it on the trimmed path
Heap difference reported by the kernel.
I also replicated all results on the standard Raspberry Pi raspbian distribution. The results are 100% identical, so they're not worth including. It does give more evidence that in Linux systems with more of a focus on low power do not change glib defaults.
For fun I repeated the same experiment except I created 500,000 Fiber objects, then freed all of them using mrb_close with and without trim. The results are similar. Even at program exit without calling malloc_trim the program consumes 900 mb of memory, whereas calling malloc_trim right after mrb_close memory usage drops back to 0.3 mb.
(The heap visualizer as it is right now does not function well with this amount of memory usage)
Even after allocating 933MB of memory and marking all of it free, as the mrb_close function correctly does, that still does not trigger glibc defaults on marking memory as unused to the kernel! This is a major problem!
And finally, changing the code for using 4 mrb_states and closing half of them. Given the previous knowledge it also provides a predictable pattern. Changing the test program a bit
mrb_state *states[] = { mrb_open(), mrb_open(), mrb_open(), mrb_open() };
for(uint32_t i = 0; i < 4; ++i) {
mrb_load_string(states[i], "$a = []; $b = []; $c = []; $d = []; 2_500.times { $a.push(Fiber.new {}) }; 2_500.times { $b.push(Fiber.new {})}; 2_500.times { $c.push(Fiber.new {})}; 2_500.times { $d.push(Fiber.new {})}; $b = nil; $d = nil; GC.start;");
}
mrb_close(states[0]);
mrb_close(states[2]);
Full defaults
Using malloc_trim
Knowing this I tried mruby-thread. Because it reads the parent mrb_state from the parent thread, copies that state into a child thread, and then deletes the child thread on join, the kernel reclaims the memory on joining the child thread.
About the glib defaults. We can control them through documented parameters, either through env vars or glibc compile time defines. I followed the research done with C Ruby by setting M_ARENA_MAX=2 and running the default program. An interesting difference is I do not observe a change in behavior running with that env var set with the default program, the heap output is the same as the default unpatched program. I also don't think it's responsible to make the end user set some obscure system parameters anyway.
It's a common scenario using linux and default glib even for linux systems destined for lower power devices. The default glibc allocator behavior defaults are dramatically out of line for this situation. This situation is obscure enough that I strongly suspect other embedded linux systems do not change any defaults either.
Because of that I feel we should introduce malloc_trim into mruby. The conditions for usage are if the compilation target uses glibc and mrb_malloc uses the default glibc allocator. I observed that calling malloc_trim after a major GC produces the same results as calling it outside of the VM execution. C Ruby reports the same behavior. I think that calling malloc_trim after a full GC is the most appropriate place as I'm not sure what the performance implications are if we call on every mruby page free. Also, because a host program can open and close mrb_state at will we should also call malloc_trim after freeing all the memory used.
I think the detection should go into the Rake tasks and set a define for the compiler, say MRB_GLIB_MALLOC_TRIM, and then within the C code do #ifdef MRB_GLIB_MALLOC_TRIM on that. These are simple additions that I will make a PR for. I am providing extensive documentation as to why here. I am also asking if there are ideas for a different way of detecting the environment for glibc and calling from the code.

This affects so many mgems (including like mruby-env and mruby-process... which are referenced in many mruby products)!!
IMO I agree with your intention that current prototype requires a redundant argument such like "String", so how about introducing newly named function like mrb_convert_type_sym ?

- Adds a few methods to

gcc.rake. That way if a user has a custombuild_config.rbthey can remove the define if they wish, like if they are using a different allocator than glib.

Skip some `Math.atan2()` tests. Linux `atan2(3)` man page says: ``` If y is positive infinity (negative infinity) and x is positive infinity, +pi/4 (-pi/4) is re‐ turned. ``` But on Microsoft VC/MinGW, `atan2()` returns `NaN` if either of arguments is infinite. So we skip those tests on the platforms.

Separate jump destination check in `OP_R_RETURN`. In the past code, the current `callinfo (ci)` was modified, thus it was possible to pop `ci` beyond the `cibase`, that could cause out of memory bound access for the code like the following: ```ruby def m2 lambda { Proc.new { return :return # return from the method } }.call.call :never_reached end p m2 ```

Adding malloc_trim call on full GC
I am wondering whether it may be better to specify manually via a macro define, e.g. MRB_USE_MALLOC_TRIM.
In that case, we don't have to add a complex detection code. No worry about cross-compiling nor compiler portability.
