Runtime dynamic memory tracing #2487

bogdanm · 2016-08-18T13:22:44Z

This commit adds a dynamic memory tracer that calls a callback whenever
one of the basic memory allocation functions (malloc, realloc, calloc,
free) is called. The operation of the tracer is guarded by the
MBED_MEM_TRACING_ENABLED macro.

bogdanm · 2016-08-18T13:24:38Z

Do not merge. Pushing it just for comments. At the very least, this PR should be able to easily integrate with #2442 before it's merged.

Tests will follow shortly.

I force-pushed a refactor of the previous commit, which should make it easier to integrate with #2442. The functionality didn't change.

could this use mbed-trace as default .. :) application can then protect prints because printf is not thread safe,,,,,

Interesting point, thank you. I've never used mbed-trace myself, but I'll take a look at it and I'll make the necessary changes.

+1 for standardizing tracing. Although isn't malloc already not thread-safe?

true, malloc is not thread either i think.

After looking at mbed-trace, I'm a bit hesitant to use it here instead of printf. It looks like a very nice tracing library, but that's the problem: it's a library that adds to the flash size, has its own needs in terms of memory allocation and its own configuration. printf looks to be a good default solution, with minimal impact on setup and flash size.

could be,, anyway we probably want to use trace library for this for all our test apps we have ;) ..

jupe · 2016-08-18T16:04:31Z

sounds much better approach :) i would like to try this..

do we really need to select which of allocation trace we track? I think it is enough "all or nothing" . if we track mallocs we cannot calculate summary without free and realloc tracks as well. I'm fine with this also, but like most simplified solution which covers 99.9% of use cases... of course mask-bit check doesnt need much ticks, but because allocation is quite low level function it should be as fast as possible and couple extra ticks might causes some strange issues..

While the mask is not required, it might be useful in some cases. Also, if a couple of ticks might cause some strange issues, my guess is that something is quite wrong with the rest of your program 😄

thats true, it shouldnt cause any issue, but you never know 🤔

Few notes but LGTM 👍

(from docs) For pointers, * is adjacent to a name (analogin_t *obj). This should also be applied to return types
We're using the TOOLCHAIN_XXX for compiler type. Is it not time to start using symbols emitted by the compilers or is there a known case where this fails or is inconsistent

do we really need to select which of allocation trace we track? I think it is enough "all or nothing"

I'd have to agree, this hooks based on compile time option so why not also just enable by default or allow the tracing type to be config as well. Seems right now you need to add a mbed_mem_trace_setup to the application which is a shame unless I've missed something. That way something works out of the box with no source mods. Seems could just set the default mask to enable all and not call mbed_mem_trace_setup at all by default.

jupe · 2016-08-19T18:20:46Z

Seems could just set the default mask to enable all and not call mbed_mem_trace_setup at all by default.

I agree with this also, enable all by default so there is no require to call mbed_mem_trace_setup at all if application doesn't want to.

does this correctly show the caller address? Especially if debug is turned on, I would imagine this returns and address inside __wrap__malloc_r, which would not be very helpful.

We're using the TOOLCHAIN_XXX for compiler type. Is it not time to start using symbols emitted by the compilers or is there a known case where this fails or is inconsistent

@sg-, sorry, I don't understand from your comment what's the actual issue here. Should we not use TOOLCHAIN_XXX for compiler type? If not, what's the alternative?

I'd have to agree, this hooks based on compile time option so why not also just enable by default.

Because people won't like to have all their allocation calls hooked by default if they don't care about tracing the memory usage. See @jupe's comments above about optimizing this and cycle counts (I don't agree with them 100%, but it seems like there's a case for performance optimization in this area).

EDIT: by looking at the code, it seems like the memory allocation functions are wrapped by default anyway, so we can simplify this a bit.

Seems could just set the default mask to enable all and not call mbed_mem_trace_setup at all by default.

I can add configuration options for tracing, sure. I'll do that today.

bogdanm · 2016-08-22T10:59:27Z

Seems right now you need to add a mbed_mem_trace_setup to the application which is a shame unless I've missed something.

The problem is with binary SDK builds. If you want to proide this feature to the binary SDK users, you'll also want to enable it, thus defining MBED_MEM_TRACE_ENABLED at SDK compile time. However, if that also enables tracing by default, it means that the binary SDK users will have to manually disable tracing at the beginning of their program, since tracing will now be on by default in their apps. You'll have this problem with any compile-time macro and SDK binary build, I think.

bogdanm · 2016-08-22T12:31:47Z

The latest commit implements a few things requested in this PR:

no more masks for tracing
caller_addr() moved one level up, so it doesn't always return __wrap__something

bogdanm · 2016-08-22T15:54:53Z

Added tests (will probably fail since the trace macro is not yet enabled).

jupe · 2016-08-22T16:03:44Z

how that test required flag should be defined? I think that trace should not be enabled by default,, only for this test,,

bogdanm · 2016-08-22T16:04:55Z

Ideally, the test would have its own mbed_app.json file, and we'd define the macro in this file. I believe there's a feature request opened for this.

jupe · 2016-08-22T16:08:56Z

does it means that test will fail as long as that feature is not there?

bogdanm · 2016-08-22T16:12:07Z

I think @bridadan can help with that :)

jupe · 2016-08-22T16:15:54Z

just wondering why test builds are handled different way than normal applications if it doesn't support mbed_app.json file,,,?

bogdanm · 2016-08-22T16:19:47Z

This is something that deserves an issue of its own. I thought I saw one, but I can't find it anymore. Still looking for it.

@c1728p9

This commit adds a dynamic memory tracer that calls a callback whenever one of the basic memory allocation functions (malloc, realloc, calloc, free) is called. The operation of the tracer is guarded by the 'MBED_MEM_TRACING_ENABLED` macro. Infinite recursion during tracing is guarded by using atomic increment/decrement primitives on the `trace_level` variable. Thanks to @c1728p9 and @Heky for their help and suggestions.

Without this in place, traces might be lost if a another thread interrupts a memory function at the right time.
