Paul Sokolovsky 243f8988be unix/mpconfigport.h: Include stdio.h by default.
This allows to use printf() in a any source file with unix port, for quick
debugging.

Paul Sokolovsky 68815901d4 unix: Disable MICROPY_GC_ALLOC_THRESHOLD for minimal build. 2016-07-21 00:37:53 +03:00
Paul Sokolovsky bd6622abe8 unix: Cache libaxtls.a in local build dir.
Allows to build the library variant for other ports in parallel.

Paul Sokolovsky 20283aec10 extmod/modussl_axtls: Further changes to allow alternative SSL modules.
Make variable MICROPY_SSL_AXTLS=1 should be defined to activate modussl_axtls
and link with -laxtls.

Damien George ee622cc1ed unix/mpthreadport: Adjust minimum thread stack, and stack limit check.
The minimum thread stack size is set by pthreads (16k bytes) so we must
use that value for our minimum.  The stack limit check is also adjusted
to work correctly for 32-bit builds.

Damien George 3096928d5a unix: Disable the GIL to improve performance of non-thread code.
Threading support is still very new so stay conservative at this point
and enable threading without the GIL.  This requires users to protect
concurrent access of mutatable Python objects (eg lists) with locks at
the Python level (something you should probably do anyway).  The
advantage is that there is less of a performance hit for non-threaded
code, because the VM does not need to constantly release/acquire the GIL.

In the future the GIL will be made more efficient.  There is also room to
improve the efficiency of non-GIL code by not using mutex's if there is
only one thread active.

Paul Sokolovsky 520f35632d unix/main: When preparing sys.path, allocate exact strings on uPy heap.
Due to the way modern compilers work (allocating space for stack vars once
at tha start of function, and deallocating once on exit from), using
intermediate stack buffer of big size caused blockage of 4K (PATH_MAX)
on stack for the entire duration of MicroPython execution.

Paul Sokolovsky 649b69a1db unix/main: Improve help for -X options a bit. 2016-07-08 20:53:08 +03:00
Paul Sokolovsky 0e5e14fe7c unix/main: Error out on unknown value of suffix in -X heapsize= option.
E.g. -X heapsize=16Kfoo, -X heapsize=1G will lead to error.
2016-07-08 20:49:41 +03:00
Paul Sokolovsky d83177b248 unix/mpconfigport_minimal.h: Allow to print a string within 1KB of heap.
By adjusting parser allocation policy.

Paul Sokolovsky e965d2b82a unix/Makefile: Make "minimal" build be minimal again. 2016-07-03 00:10:58 +03:00
Paul Sokolovsky 43241ceaac unix: Enable btree module.
But disable it for coverage build, as its extra warninsg aren't compatible
with K&R C BerkeleyDB uses.
2016-07-02 15:26:07 +03:00
Damien George df95f52583 py/modthread: Allow to properly set the stack limit of a thread.
We rely on the port setting and adjusting the stack size so there is
enough room to recover from hitting the stack limit.

Damien George 94d2919b77 unix/modtime: Release the GIL when sleeping. 2016-06-28 11:28:50 +01:00
Damien George f443504f86 unix/mpthreadport: Suppress compiler warning about unused arguments. 2016-06-28 11:28:50 +01:00
Damien George f1dbd2909e unix/gccollect: Provide declaration of exported function. 2016-06-28 11:28:50 +01:00
Damien George c2508ac8bd unix/mpthreadport: Use SA_SIGINFO for GC signal handler.
SA_SIGINFO allows the signal handler to access more information about
the signal, especially useful in a threaded environment.  The extra
information is not currently used but it may prove useful in the future.

Damien George dbd54e0b5b unix: Implement garbage collection with threading.
This patch allows any given thread to do a proper garbage collection and
scan all the pointers of all active threads.
2016-06-28 11:28:49 +01:00
Damien George f1b6db2218 unix/file: If write syscall returns because of EINTR then try again.
As per PEP-475.
2016-06-28 11:28:49 +01:00
Damien George 801d1b3803 py/modthread: Implement lock object, for creating a mutex. 2016-06-28 11:28:49 +01:00
Damien George 707f98f207 py/modthread: Add stack_size() function. 2016-06-28 11:28:48 +01:00
Damien George a791be936a unix: Add basic thread support using pthreads.
Has the ability to create new threads.
2016-06-28 11:28:48 +01:00
Damien George 330165a2cc py: Add MP_STATE_THREAD to hold state specific to a given thread. 2016-06-28 11:09:31 +01:00
Martin Müller f2892bd77d unix: Fix Makefile to handle gc-sections linker flags on Mac OS.
The linker flag --gc-sections is not available on the linker used on
Mac OS X which results in an error when linking micropython on Mac OS X.
Therefore move this option to the LDFLAGS_ARCH variable on non Darwin
systems. According to http://stackoverflow.com/a/17710056 the equivalent
to --gc-sections is -dead_strip thus this option is used for the
LDFLAGS_ARCH on Darwin systems.

Paul Sokolovsky e68811dbbf unix/modmachine: Enable time_pulse_us() function. 2016-06-19 00:21:17 +03:00
Paul Sokolovsky ad229477c6 unix/modmachine: Include PinBase class. 2016-06-18 23:40:28 +03:00
Paul Sokolovsky 07209f8592 all: Rename mp_obj_type_t::stream_p to protocol.
It's now used for more than just stream protocol (e.g. pin protocol), so
don't use false names.
2016-06-18 18:44:57 +03:00
Paul Sokolovsky cbffd0aadd unix: Disable FatFs VFS for normal build, keep enabled for coverage.
It's enabled mostly for unit testing, and we do that in full with coverage
build.
2016-06-18 00:58:57 +03:00
Paul Sokolovsky 7c8d76fad3 unix/alloc: Make coverage build and its overzealous warnings happy. 2016-06-18 00:36:13 +03:00
Paul Sokolovsky c9598604c6 unix/alloc: Add option to use uPy's alloc-exec implementation even for libffi.
When built for Linux, libffi includes very bloated and workaround exec-alloc
implementation required to work around SELinux and other "sekuritee" features
which real people don't use. MicroPython has own alloc-exec implementation,
used to alloc memory for @micropython.native code. With this option enabled,
uPy's implementation will override libffi's. This saves 11K on x86_64 (and
that accounts for more than half of the libffi code size).

TODO: Possibly, we want to refactor this option to allow either use uPy's
implementation even for libffi, or allow to use libffi's implementation even
for uPy.
2016-06-18 00:18:01 +03:00
Paul Sokolovsky 9b43a7d1be unix/Makefile: libffi: Build with -Os.
Also try to use -fno-exceptions. Other options taken from libffi's configure
defaults.

Paul Sokolovsky 6f8880d0ab unix: Move "utime" module config to C level instead of make level. 2016-06-17 23:35:00 +03:00
Paul Sokolovsky df453f0652 unix: Time to build with --gc-sections.
This actually saves "only" 6K for x86_64 build, as we're still more or less
careful to #ifdef unneeded code. But relying on --gc-sections in a "lazy"
manner would allow to make #ifdef'ing less pervasive (not suggested right
away, but an option for the future).

Paul Sokolovsky acaa30b604 unix: Deprecate support for GNU Readline (MICROPY_USE_READLINE=2).
MicroPython own readline implementation is superior now by providing
automatic indentation and completion (completion for GNU Readline was
never implemented). MICROPY_USE_READLINE=2 also wasn't build for a long
time and probably broken.

If GNU Readline is still beneficial for some cases, it can be achieved
with external wrappers like "rlwrap" (there will be the same level of
functionality, as again, there never was deep integration, like completion
support).
2016-06-16 03:28:58 +03:00
Paul Sokolovsky b5190f1df3 unix/mpconfigport_minimal.h: Clearly mark where user-define config ends.
TODO: Do the same for other config files.
2016-06-16 01:20:32 +03:00
Paul Sokolovsky cd796f85af unix: Unbreak "minimal" target by disabling FatFs.
Was broken since introduction of FatFs support.
2016-06-16 00:03:24 +03:00
Paul Sokolovsky 0f5bf1aafe py/mpconfig.h: MP_NOINLINE is universally useful, move from unix port. 2016-06-15 23:52:00 +03:00
Robert HH ee009d713a extmod/vfs_fat.c: Add vfs.stat().
The call to stat() returns a 10 element tuple consistent to the os.stat()
call. At the moment, the only relevant information returned are file
type and file size.

Paul Sokolovsky 4889b6ff9b unix/Makefile: "make axtls": Automatically fetch submodules if missing.
Try to emulate "you can build without reading instructions" behavior as far
as possible.
2016-05-28 21:03:48 +03:00
Paul Sokolovsky 6055d411a9 unix/mpconfigport.mk: Document MICROPY_STANDALONE make-level option.
Avoid using system libraries, use copies bundled with MicroPython as
submodules (currently affects only libffi, other dependencies either
already used as bundled-only (axtls), or can't be bundled (so far),
like libjni).
2016-05-28 20:38:14 +03:00
Paul Sokolovsky f5d63bcd23 unix: Enable "ussl" module.
ussl was in testing mode for 8 months, and now enabled in other ports
(e.g. esp8266), so time for unix port to catch up.
2016-05-26 02:12:11 +03:00
Paul Sokolovsky 37f9761801 unix/Makefile: nanbox build is not compatible with modussl, disable. 2016-05-26 02:11:17 +03:00
Damien George 2133924e46 unix: Support frozen packages.
To use, put your directory structure with .py files in frozen/ and then:

    make FROZEN_MPY_DIR=frozen
2016-05-23 15:19:53 +01:00
Paul Sokolovsky 1b5abfcaae py/objstr: Implement str.center().
Disabled by default, enabled in unix port. Need for this method easily
pops up when working with text UI/reporting, and coding workalike
manually again and again counter-productive.
2016-05-22 00:13:44 +03:00
Paul Sokolovsky b580958216 unix/unix_mphal: Implement mp_hal_ticks_us().
Similar to existing mp_hal_ticks_ms().
