The code conventions suggest using header guards, but do not define how
those should look like and instead point to existing files. However, not
all existing files follow the same scheme, sometimes omitting header guards
altogether, sometimes using non-standard names, making it easy to
accidentally pick a "wrong" example.
This commit ensures that all header files of the MicroPython project (that
were not simply copied from somewhere else) follow the same pattern, that
was already present in the majority of files, especially in the py folder.
The rules are as follows.
Naming convention:
* start with the words MICROPY_INCLUDED
* contain the full path to the file
* replace special characters with _
In addition, there are no empty lines before #ifndef, between #ifndef and
one empty line before #endif. #endif is followed by a comment containing
the name of the guard macro.
py/grammar.h cannot use header guards by design, since it has to be
included multiple times in a single C file. Several other files also do not
need header guards as they are only used internally and guaranteed to be
included only once:
* MICROPY_MPHALPORT_H
* mpconfigboard.h
* mpconfigport.h
* mpthreadport.h
* pin_defs_*.h
* qstrdefs*.h
Got tired of running rm -rf manually. Make should clean, and should clean
fast. Also, fix always-running config-related commands (by having per-board
merged configs).
For consistent Pin/Signal class hierarchy. With it, Signal is a proper
(while still ducktyped) subclass of a Pin, and any (direct) usage of Pin
can be replace with Signal.
As stmhal's class is reused both as machine.Pin and legacy pyb.Pin,
high/low methods actually retained there.
There're a lot of changes and fixes in 1.8 regarding IP stack,
incompatible with previous Zephyr versions, so supporting them
doesn't make sense.
This is the last commit which should build with Zephyr 1.7.
As Zephyr currently doesn't handle MTU itself (ZEP-1998), limit amount
of data we send on our side.
Also, if we get unsuccessful result from net_nbuf_append(), calculate
how much data it has added still. This works around ZEP-1984.
Internal structure of k_fifo changed between 1.7 and 1.8, so we need
to abstract it away. This adds more functions than currently used, for
future work.
Without this, if there's a large chunk of data coming from hardware (e.g.
clipboard paste, or fed programmatically from the other side of the console),
there's a behavior of initial mass fill-in of the buffer without any
consumption, which starts much later and doesn't catch up with further
filling, leading to buffer overflow.
