Now that error string compression is supported it's more important to have
consistent error string formatting (eg all lowercase English words,
consistent contractions). This commit cleans up some of the strings to
make them more consistent.
This commit adds Loop.new_event_loop() which is used to reset the singleton
event loop. This functionality is put here instead of in Loop.close() to
make it possible to write code that is compatible with CPython.
Because the atomic section starts after checking whether the scheduler
state is pending, it's possible it can become a different state by the time
the atomic section starts.
This is especially likely on ports where MICROPY_BEGIN_ATOMIC_SECTION is
implemented with a mutex (i.e. it might block), but the race exists
regardless, i.e. if a context switch occurs between those two lines.
This macro is used to implement global serialisation, typically by
disabling IRQs. On the unix port, if threading is enabled, use the
existing thread mutex (that protects the thread list structure) for this
purpose. Other places in the code (eg the scheduler) assume this macro
will provide serialisation.
Based on eg 1e6fd9f2b4, it's understood that
the intention for unix builds is that regular builds disable assert, but
the coverage build should set -O0 and enable asserts.
It looks like this didn't work (even before variants were introduced, eg at
v1.11) -- coverage always built with -Os and -DNDEBUG.
This commit makes it possible for variants to have finer-grained control
over COPT flags, and enables assert() and -O0 on coverage builds.
Other variants already match the defaults so they have been updated.
TimeoutError was added back in 077812b2ab for
the cc3200 port. In f522849a4d the cc3200
port enabled use of it in the socket module aliased to socket.timeout. So
it was never added to the builtins. Then it was replaced by
OSError(ETIMEDOUT) in 047af9b10b.
The esp32 port enables this exception, since the very beginning of that
port, but it could never be accessed because it's not in builtins.
It's being removed: 1) to not encourage its use; 2) because there are a lot
of other OSError subclasses which are not defined at all, and having
TimeoutError is a bit inconsistent.
Note that ports can add anything to the builtins via MICROPY_PORT_BUILTINS.
And they can also define their own exceptions using the
MP_DEFINE_EXCEPTION() macro.
In this part of the code there is no way to get the ** operator, so no need
to check for it.
This commit also adds tests for this, and other related, invalid const
operations.
Recent builds are failing with the following error:
Error: pkg-config 0.29.2 is already installed
Assuming this will be the case form now on, we don't have to install
pkgconfig anymore.
The latest version of BTstack has a bug fixed so that it correctly
configures scan parameters if they are set right after activating the
stack. This means that BLE.gap_scan() will correctly set the scanning to
passive and so SCAN_RSP events are not passed through, so we don't need to
explicitly filter them in our bindings.
Making it more specific to use 0x02 for display with an aspect ratio > 2
(resolutions 96x16 and 128x32) and 0x12 for all other sizes as recommended
by @mcauser. Tested with a 64x32 display which did not work before.
The decompression of error-strings is only done if the string is accessed
via printing or via er.args. Tests are added for this feature to ensure
the decompression works.
