Builds have been broken since reworking autogeneration in c618f91 and
related, this gets fixed here by applying similar qstr generation logic
for the msvc builds: c files are only preprocessed when changed (or not
yet preprocessed) and the concatenated output is fed into makeqstrdefs.py.
To speed up this process, the concatenated output is already filtered to
contain only lines which makeqstrdefs really needs: this makes the qstr
generation stage about twice as fast (checked on different machines).
Note this still needs some work: currently all source files are always
preprocessed no matter which one actually changed, moreover that happens
file by file without any parallellism so builds are painstakingly slow.
- add template rule that converts a specified source file into a qstring file
- add special rule for generating a central header that contains all
extracted/autogenerated strings - defined by QSTR_DEFS_COLLECTED
variable. Each platform appends a list of sources that may contain
qstrings into a new build variable: SRC_QSTR. Any autogenerated
prerequisities are should be appened to SRC_QSTR_AUTO_DEPS variable.
- remove most qstrings from py/qstrdefs, keep only qstrings that
contain special characters - these cannot be easily detected in the
sources without additional annotations
- remove most manual qstrdefs, use qstrdef autogen for: py, cc3200,
stmhal, teensy, unix, windows, pic16bit:
- remove all micropython generic qstrdefs except for the special strings that contain special characters (e.g. /,+,<,> etc.)
- remove all port specific qstrdefs except for special strings
- append sources for qstr generation in platform makefiles (SRC_QSTR)
The config variable MICROPY_MODULE_FROZEN is now made of two separate
parts: MICROPY_MODULE_FROZEN_STR and MICROPY_MODULE_FROZEN_MPY. This
allows to have none, either or both of frozen strings and frozen mpy
files (aka frozen bytecode).
Calling it from mp_init() is too late for some ports (like Unix), and leads
to incomplete stack frame being captured, with following GC issues. So, now
each port should call mp_stack_ctrl_init() on its own, ASAP after startup,
and taking special precautions so it really was called before stack variables
get allocated (because if such variable with a pointer is missed, it may lead
to over-collecting (typical symptom is segfaulting)).
The default bahaviour for debug builds is to show dialog boxes for asserts
and invalid parameter handling. This is not so nice in general and causes
the Appveyor debug builds to hang because the io\file_seek.py test passes
a closed file descriptor to lseek. Disable this behaviour by printing
assert messages to the output instead of showing the dialog, and by
disabling 'invalid' parameter handling which causes the affected functions
to just return an error and set errno appropriately.
This builds upon the changes made in 2195046365. Using signal() does not
produce reliable results so SetConsoleCtrlHandler is used, and the handler
is installed only once during initialization instead of removing it in
mp_hal_set_interrupt_char when it is not strictly needed anymore, since
removing it might lead to Ctrl-C events being missed because they are
fired on a seperate thread which might only become alive after the handler
was removed.
Appveyor is like Travis, but for Windows builds. The appveyor.yml configuration
will build the msvc port in all configuration/platform conbinations,
and run the tests for each of those.
This allows multiple versions (e.g. Debug/Release, x86/x64) of micropython.exe
to co-exist instead and also solves potential problems where msbuild does not
completely rebuild the output and/or pdb files when switching between builds,
which in turn can cause linker errors in dependent projects.
By default exe/map/... files go in windows/build/$(Configuration)$(Platform)
After each build micropython.exe is still copied from the above directory to
the windows directory though, as that is consistent with the other ports and
the test runner by default uses that location as well.
Also rename env.props -> path.props which is a clearer name,
and add ample documentation in the affected build files.
(also see discussion in #1538)
- add mp_int_t/mp_uint_t typedefs in mpconfigport.h
- fix integer suffixes/formatting in mpconfig.h and mpz.h
- use MICROPY_NLR_SETJMP=1 in Makefile since the current nlrx64.S
implementation causes segfaults in gc_free()
- update README
The BSD stuff is a copy from the unix makefile but at least there it
makes some sense, a windows makefile on BSD doesn't.
The -lmman flag is probably for mmap functions but there is no other build
support for it on windows so just that flag won't cut it anyway.
- use correct 'mingw-w64' package name
- small grammar fixes
- modify Cygwin build instructions to use that same compiler as well: the
original mingw is stuck at gcc v4.7 and does not seem to be updated anymore
- make it clear thet uPy also builds using Visual Studio versions > 2013
Ubuntu's mingw32 has gcc 4.2.1, which is rather old and has incorrect
non-initialized variable analysis which produces warnings, which
per MicroPython default settings get turned into errors.
py/mphal.h contains declarations for generic mp_hal_XXX functions, such
as stdio and delay/ticks, which ports should provide definitions for. A
port will also provide mphalport.h with further HAL declarations.
Also make sleep.c self-contained by moving initialization code,
instead of having part of the code in init.c, and add a header file
to accomodate this.
msec_sleep() now uses the usleep() implementation as well.
If VT100 support is not available then a given implementation of
mp_hal_erase_line_from_cursor might need to know the number of characters
to erase.
This patch does not change generated code when VT100 is supported, since
compiler can optimise away the argument.
- add SEEK_XXX definitions, this fixes missing definition in py/stream.c
- move R_OK from realpath.c and add W_OK/F_OK defintions
- move STDXXX_FILENO definitions from mpconfigport for consistency
This allows using (almost) the same code for printing floats everywhere,
removes the dependency on sprintf and uses just snprintf and
applies an msvc-specific fix for snprintf in a single place so
nan/inf are now printed correctly.
- by default look for a user.props in the msvc directory, which is more convenient
than the built-in way of looking for such file in the user's home directory
- make git ignore the file
