The PR removed the bulk of non-newlib headers from the NodeMCU source base.
app/libc has now been cut down to the bare minimum overrides to shadow the
corresponding functions in the SDK's libc. The old c_xyz.h headerfiles have been
nuked in favour of the standard <xyz.h> headers, with a few exceptions over in
sdk-overrides. Again, shipping a libc.a without headers is a terrible thing to do. We're
still living on a prayer that libc was configured the same was as a default-configured
xtensa gcc toolchain assumes it is. That part I cannot do anything about, unfortunately,
but it's no worse than it has been before.
This enables our source files to compile successfully using the standard header files,
and use the typical malloc()/calloc()/realloc()/free(), the strwhatever()s and
memwhatever()s. These end up, through macro and linker magic, mapped to the
appropriate SDK or ROM functions.
* Add support of counting of interrupts
* Update the timestamp when interrupt happens during dispatch. Also
clear out interrupts when setting up a new callback
* Check the return code of the read function when doing crypto.fhash so that we don't pass negative lengths to the hashing functions
* Fix various assert failures in the LVM arising from rotables. No functional change
* Add the gpio interrupt time to the callback (and pass it from the interrupt handler)
* Get the PC right in the perf module
* Make the headers static in the websocket module
* Fix the documentation
As with the last commit this rolls up the follwowing, but include the various
review comments on the PR.
- **Documentation changes**. I've added the taks FAQ as a stub new Extension
developer FAQ, and split the old FAQ into a Lua Developer FAQ and a Hardware
FAQ.
- **Tasking I/F**. New `app/task/Makefile`, `app/task/task.c`,
`app/include/task/task.h` and `app/Makefile` as per previous commit. Cascade
changes to `app/driver/uart.c`, `app/include/driver/uart.h`,
`app/user/user_main.c` and `app/modules/node.c`
- **GPIO Rework** to `app/modules/gpio.c` and `pin_map.[hc]`, `platform.[hc]`
in `app/platform`
- **Other Optimisations** Move the `platform_*_exists()` from
`app/platform/common.c` to static inline declarations in `platform.h` as
this generates faster, smaller code. Move lgc.a routines out of iram0.
Module creation & registration now made a lot simpler. In essence,
each module file is now self-contained and only needs a
NODEMCU_MODULE(MYNAME, "myname", myname_map, luaopen_myname);
line to both be automatically recognised by the Lua initialization
as well as honor the LUA_USE_MODULES_MYNAME #define.
As per #810 & #796, only LUA_OPTIMIZE_MEMORY=2 & MIN_OPT_LEVEL=2 are
supported when building. This commit effects that limitation.
With this change modules/auxmods.h no longer needs to be updated for
every new module, nor do module writers need to cater for a hypothetical
LUA_OPTIMIZE_MEMORY < 2 scenario.
