2024-03-07all: Remove the "STATIC" macro and just use "static" instead.Angus Gratton
The STATIC macro was introduced a very long time ago in commit d5df6cd44a433d6253a61cb0f987835fbc06b2de. The original reason for this was to have the option to define it to nothing so that all static functions become global functions and therefore visible to certain debug tools, so one could do function size comparison and other things. This STATIC feature is rarely (if ever) used. And with the use of LTO and heavy inline optimisation, analysing the size of individual functions when they are not static is not a good representation of the size of code when fully optimised. So the macro does not have much use and it's simpler to just remove it. Then you know exactly what it's doing. For example, newcomers don't have to learn what the STATIC macro is and why it exists. Reading the code is also less "loud" with a lowercase static. One other minor point in favour of removing it, is that it stops bugs with `STATIC inline`, which should always be `static inline`. Methodology for this commit was: 1) git ls-files | egrep '\.[ch]$' | \ xargs sed -Ei "s/(^| )STATIC($| )/\1static\2/" 2) Do some manual cleanup in the diff by searching for the word STATIC in comments and changing those back. 3) "git-grep STATIC docs/", manually fixed those cases. 4) "rg -t python STATIC", manually fixed codegen lines that used STATIC.

2023-12-21extmod/modselect: Handle growing the pollfds allocation correctly.Jim Mussared
The poll_obj_t instances have their pollfd field point into this allocation. So if re-allocating results in a move, we need to update the existing poll_obj_t's. Update the test to cover this case. Fixes issue #12887. This work was funded through GitHub Sponsors. Signed-off-by: Jim Mussared <jim.mussared@gmail.com>

See previous commit for details of these functions. As of this commit, these still call the old hook macros on all ports. This work was funded through GitHub Sponsors. Signed-off-by: Angus Gratton <angus@redyak.com.au>

2023-08-07extmod/modselect: Remove undocumented support for flags arg to poll.Damien George
The signature of this method was poller.poll(timeout=-1, flags=0, /) but the flags argument was not documented and is not CPython compatible. So it's removed in this commit. (The optional flags remains for the ipoll() method, which is documented.) Signed-off-by: Damien George <damien@micropython.org>
2023-08-07extmod/modselect: Add optimisation to use system poll when possible.Damien George
A previous commit removed the unix-specific select module implementation and made unix use the common one. This commit adds an optimisation so that the system poll function is used when polling objects that have a file descriptor. With this optimisation enabled, if code registers both file-descriptor-based objects, and non- file-descriptor-based objects with select.poll() then the following occurs: - the system poll is called for all file-descriptor-based objects with a timeout of 1ms - then the bare-metal polling implementation is used for remaining objects, which calls into their ioctl method (which can be in C or Python) In the case where all objects have file descriptors, the system poll is called with the full timeout requested by the caller. That makes it as efficient as possible in the case everything has a file descriptor. Benefits of this approach: - all ports use the same select module implementation - the unix port now supports polling of all objects and matches bare metal implementations - it's still efficient for existing cases where only files and sockets are polled (on unix) - the bare metal implementation does not change - polling of SSL objects will now work on unix by calling in to the ioctl method on SSL objects (this is required for asyncio ssl support) Note that extmod/vfs_posix_file.c has poll disable when the optimisation is enabled, because the code is not reachable when the optimisation is used.
