While just a websocket is enough for handling terminal part of WebREPL,
handling file transfer operations requires demultiplexing and acting
upon, which is encapsulated in _webrepl class provided by this module,
which wraps a websocket object.
The C standard says that left-shifting a signed value (on the LHS of the
operator) is undefined. So we cast to an unsigned integer before the
shift. gcc does not issue a warning about this, but clang does.
- msvc preprocessor output contains full paths with backslashes so the
':' and '\' characters needs to be erased from the paths as well
- use a regex for extraction of filenames from preprocessor output so it
can handle both gcc and msvc preprocessor output, and spaces in paths
(also thanks to a PR from @travnicekivo for part of that regex)
- os.rename will fail on windows if the destination file already exists,
so simply attempt to delete that file first
Qstr auto-generation is now much faster so this optimisation for start-up
time is no longer needed. And passing "-s -S" breaks some things, like
stmhal's "make deploy".
E.g. for stmhal, accumulated preprocessed output may grow large due to
bloated vendor headers, and then reprocessing tens of megabytes on each
build make take couple of seconds on fast hardware (=> potentially dozens
of seconds on slow hardware). So instead, split once after each change,
and only cat repetitively (guaranteed to be fast, as there're thousands
of lines involved at most).
If make -B is run, the rule is run with $? empty. Extract fron all file in
this case. But this gets fragile, really "make clean" should be used instead
with such build complexity.
When there're C files to be (re)compiled, they're all passed first to
preprocessor. QSTR references are extracted from preprocessed output and
split per original C file. Then all available qstr files (including those
generated previously) are catenated together. Only if the resulting content
has changed, the output file is written (causing almost global rebuild
to pick up potentially renumbered qstr's). Otherwise, it's not updated
to not cause spurious rebuilds. Related make rules are split to minimize
amount of commands executed in the interim case (when some C files were
updated, but no qstrs were changed).
- any architecture may explicitely build with qstring make
QSTR_AUTOGEN_DISABLE=1 autogeneration disabled and provide its
own list of qstrings by the standard
mechanisms (qstrdefsport.h).
