Damien George 5f67b03e99 stm32/servo: Only initialise TIM5 if it is needed, to save power. 2018-11-28 12:06:24 +11:00
Damien George 4f25a8b6a4 tools/pydfu.py: Improve DFU reset, and auto-detect USB transfer size.
A DFU device must be in the idle state before it can be programmed, and
this requires either clearing the status or aborting, depending on its
current state.  Code is added to do this.  And the USB transfer size is now
automatically detected so devices with a size less than 2048 bytes work
correctly.

Paul Sokolovsky 5c34c2ff7f tests/io: Update tests to use uos.remove() instead of uos.unlink().
After Unix port switches from one to another, to be consistent with
baremetal ports.

Paul Sokolovsky 80aca27a40 unix/modos: Rename unlink to remove to be consistent with other ports.
We standardized to provide uos.remove() as a more obvious and user-friendly
name.  That's what written in the docs.  The Unix port implementation
predates this convention, so update it now.

Paul Sokolovsky d94aa577a6 tests/import_long_dyn: Test for "import *" of a long dynamic name.
Such names aren't stored as qstr in module dict, and there was a bug in
"import *" handling which assumed any name in a module dict is a qstr.
2018-11-01 13:33:16 +11:00
Paul Sokolovsky 5c18730f28 py/runtime: Fix qstr assumptions when handling "import *".
There was an assumption that all names in a module dict are qstr's.
However, they can be dynamically generated (by assigning to globals()),
and in case of a long name, it won't be a qstr. Handle this situation
properly, including taking care of not creating superfluous qstr's for
names starting with "_" (which aren't imported by "import *").

stijn 06643a0df4 tests/extmod: Skip uselect test when CPython doesn't have poll().
CPython does not have an implementation of select.poll() on some
operating systems (Windows, OSX depending on version) so skip the
test in those cases instead of failing it.

Damien George e328a5d469 py/scope: Optimise scope_find_or_add_id to not need "added" arg.
Taking the address of a local variable is mildly expensive, in code size
and stack usage.  So optimise scope_find_or_add_id() to not need to take a
pointer to the "added" variable, and instead take the kind to use for newly
added identifiers.

Damien George ba92c79841 py/compile: Remove unneeded variable from global/nonlocal stmt helpers. 2018-10-28 00:38:18 +11:00
Damien George 9201f46cc8 py/compile: Fix case of eager implicit conversion of local to nonlocal.
This ensures that implicit variables are only converted to implicit
closed-over variables (nonlocals) at the very end of the function scope.
If variables are closed-over when first used (read from, as was done prior
to this commit) then this can be incorrect because the variable may be
assigned to later on in the function which means they are just a plain
local, not closed over.

Fixes issue #4272.

Damien George c2074e7b66 tests/cmdline/cmd_showbc.py: Fix test to explicitly declare nonlocal.
The way it was written previously the variable x was not an implicit
nonlocal, it was just a normal local (but the compiler has a bug which
incorrectly makes it a nonlocal).

Damien George 746dbf78d3 py/py.mk: When building axtls use -Wno-all to prevent all warnings.
Building axtls gives a lot of warnings with -Wall enabled, and explicitly
disabling all of them cannot be done in a way compatible with gcc and
clang, and likely other compilers.  So just use -Wno-all to prevent all of
the extra warnings (in addition to the necessary -Wno-unused-parameter,
-Wno-uninitialized, -Wno-sign-compare and -Wno-old-style-definition).

Fixes issue #4182.

Damien George 27ca9ab8b2 tests/import: Add .exp file for module_getattr.py to not require Py 3.7. 2018-10-23 11:56:58 +11:00
Paul Sokolovsky af5b509c75 examples/unix/ffi_example: Clean up and update the ffi example.
1. Use uctypes.bytearray_at().

Implementation of the "ffi" module predates that of "uctypes", so
initially some convenience functions to access memory were added
to ffi. Later, they landed in uctypes (which follows CPython's
ctype module).

So, replace undocumented experimental functions from ffi to
documented ones from uctypes.

2. Use more suitable type codes for arguments (e.g. "P" (const void*)
instead of "p" (void*).

3. Some better var naming.

4. Clarify some messages printed by the example.

Paul Sokolovsky dd76c8dc0f docs/library/uctypes: Add examples and make general updates.
Examples are added to the beginning of the module docs, similarly to docs
for many other modules.

Improvements to grammar, style, and clarity. Some paragraphs are updated
with better suggestions. A warning added of the effect incorrect usage of
the module may have. Describe the fact that offset range used in one
defined structure is limited.

Paul Sokolovsky c638d86660 tests/extmod/uctypes_sizeof_layout: Test for sizeof of different layout.
On almost all realistic platforms, native layout should be larger (or
equal) than packed layout.
2018-10-23 11:33:35 +11:00
Paul Sokolovsky 2411f42ccb extmod/moductypes: Make sizeof() accept "layout" parameter.
sizeof() can work in two ways: a) calculate size of already instantiated
structure ("sizeof variable") - in this case we already no layout; b) size
of structure decsription ("sizeof type"). In the latter case, LAYOUT_NATIVE
was assumed, but there should possibility to calculate size for other
layouts too. So, with this patch, there're now 2 forms:

uctypes.sizeof(struct)
uctypes.sizeof(struct_desc, layout)

Martin Dybdal 7795b2e5c3 tools/pyboard.py: In TelnetToSerial.close replace try/except with if.
Some Python linters don't like unconditional except clauses because they
catch SystemExit and KeyboardInterrupt, which usually is not the intended
behaviour.

Damien George a07e56cbd8 tests/basics/class_getattr: Remove invalid test for __getattribute__.
Part of this test was trying to test some functionality of __getattribute__
but this method name was misspelt so it wasn't doing anything useful.
Fixing the typo in this name makes the test fail because MicroPython
doesn't support user defined __getattribute__ methods.  So this part of the
test is removed.  The remaining tests are modified slightly to make it
clearer what they are testing.

Damien George 7eb29c2000 py/objtype: Remove comment about catching exc from user __getattr__.

Paul Sokolovsky 0c18633ea9 unix/modusocket: Finish socket.settimeout() implementation.
1. Return correct error code for non-blocking vs timed out socket
(POSIX returns EAGAIN for both, we want ETIMEDOUT in case of timed
out socket). To achieve this, blocking/non-blocking flag is added
to the mp_obj_socket_t, to avoid issuing fcntl() syscall each time
EAGAIN occurs. (mp_obj_socket_t used to be 8 bytes, having some room
in a standard 16-byte alloc block.)

2. Handle socket.settimeout(0) properly - in Python, that means
non-blocking mode, but SO_RCVTIMEO/SO_SNDTIMEO of 0 is infinite
timeout.

3. Overall, make sure that socket.settimeout() call switches blocking
state as expected.

Damien George 0f6f86ca49 stm32/usbd_cdc_interface: Refactor USB CDC tx code to not use SOF IRQ.
Prior to this commit the USB CDC used the USB start-of-frame (SOF) IRQ to
regularly check if buffered data needed to be sent out to the USB host.
This wasted resources (CPU, power) if no data needed to be sent.

This commit changes how the USB CDC transmits buffered data:
- When new data is first available to send the data is queued immediately
  on the USB IN endpoint, ready to be sent as soon as possible.
- Subsequent additions to the buffer (via usbd_cdc_try_tx()) will wait.
- When the low-level USB driver has finished sending out the data queued
  in the USB IN endpoint it calls usbd_cdc_tx_ready() which immediately
  queues any outstanding data, waiting for the next IN frame.

The benefits on this new approach are:
- SOF IRQ does not need to run continuously so device has a better chance
  to sleep for longer, and be more responsive to other IRQs.
- Because SOF IRQ is off, current consumption is reduced by a small amount,
  roughly 200uA when USB is connected (measured on PYBv1.0).
- CDC tx throughput (USB IN) on PYBv1.0 is about 2.3 faster (USB OUT is
  unchanged).
- When USB is connected, Python code that is executing is slightly faster
  because SOF IRQ no longer interrupts continuously.
- On F733 with USB HS, CDC tx throughput is about the same as prior to this
  commit.
- On F733 with USB HS, Python code is about 5% faster because of no SOF.

As part of this refactor, the serial port should no longer echo initial
characters when the serial port is first opened (this only used to happen
rarely on USB FS, but on USB HS is was more evident).

Damien George 53ccbe6cec stm32/usbd_cdc_interface: Handle disconnect IRQ to set VCP disconnected.

Damien George de71035e02 py/emitnative: Put None/False/True in global native const table.
So these constant objects can be loaded by dereferencing the REG_FUN_TABLE
pointer instead of loading immediate values.  This reduces the size of
generated native code (when such constants are used), and means that
pointers to these constants are no longer stored in the assembly code.

Damien George 6c6050ca43 py/emitnative: Push internal None rather than const obj where possible.
This shifts the work of loading the constant None object on to
load_reg_stack_imm(), making the handling of None more centralised.
