Jeff Epler	628d53d23c	unix/coverage: Expand mp_printf coverage tests. ... Test 'l' and 'll' sized objects. When the platform's `mp_int_t` is not 64 bits, dummy values are printed instead so the test result can match across all platforms. Ensure hex test values have a letter so 'x' vs 'X' is tested. And test 'p' and 'P' pointer printing. Signed-off-by: Jeff Epler <jepler@gmail.com>	2025-07-16 11:13:08 +10:00
Yoctopuce dev	c4a88f2ce7	py/obj: Add functions to retrieve large integers from mp_obj_t. ... This commit provides helpers to retrieve integer values from mp_obj_t when the content does not fit in a 32 bits integer, without risking an implicit wrap due to an int overflow.

Jeff Epler	fcfed6a0ea	unix/variants/coverage: Enable sys.settrace. ... The unix coverage variant should have all features enabled, so they can be tested for coverage. Therefore, enabled `MICROPY_PY_SYS_SETTRACE`. Signed-off-by: Jeff Epler <jepler@gmail.com>	2025-07-06 00:04:18 +10:00
Andrew Leech	09541b7896	py/repl: Skip private variables when printing tab completion options. ... Any '_' variables/functions in frozen modules are currently printed, when they shouldn't be. That's due to underscore names possibly existing between the start and end qstrs which are used to print the auto-complete matches. The underscore names should be skipped when iterating between the two boundary qstrs. The underscore attributes are removed from the extra coverage exp file because tab completing "import <tab>" no longer lists modules beginning with an underscore.

Jeff Epler	0ef5ede382	py/mpz: Avoid undefined behavior decrementing NULL. ... In the case where an mpz number is zero, its `len` is 0 and its `dig` is NULL. In that case, decrementing NULL via `d--` is undefined behavior according to the C specification. Restructuring the loops in this way avoids undefined behavior. Also, ensure that these cases are tested in the coverage test. This doesn't make much difference now, but would otherwise cause errors later when the undefined behavior sanitizer is employed in CI.

Andrew Leech	820485358d	unix/coverage: Add coverage test for mp_sched_schedule_node. ... Test modified to reschedule itself based on a flag setting. Without the change in the parent commit, this test executes the callback indefinitely and hangs but with the change it runs only once each time mp_handle_pending() is called.

Damien George	c3a18d74eb	extmod/modmarshal: Add new marshal module. ... This commit implements a small subset of the CPython `marshal` module. It implements `marshal.dumps()` and `marshal.loads()`, but only supports (un)marshalling code objects at this stage. The semantics match CPython, except that the actual marshalled bytes is not compatible with CPython's marshalled bytes. The module is enabled at the everything level (only on the unix coverage build at this stage). Signed-off-by: Damien George <damien@micropython.org>	2025-02-11 16:54:20 +11:00
Andrew Leech	7e14680a83	py/objringio: Add micropython.RingIO() interface for general use. ... This commit adds a new `RingIO` type which exposes the internal ring-buffer code for general use in Python programs. It has the stream interface making it similar to `StringIO` and `BytesIO`, except `RingIO` has a fixed buffer size and is automatically safe when reads and writes are in different threads or an IRQ. This new type is enabled at the "extra features" ROM level. Signed-off-by: Andrew Leech <andrew.leech@planetinnovation.com.au>	2024-09-19 18:00:44 +10:00
Michael Sawyer	230e521515	tests/ports/unix: Update and extend the modffi integer tests. ... Added the "long" modffi tests. The tests could not be added to the existing ffi_types test because two .exp files were required for the 32-bit and 64-bit results. Code common to both the ffi_types and type "long" tests was factored into ffi_int_base. ffi_types was renamed to ffi_int_types to group the related tests under the "ffi_int" prefix.

Angus Gratton	a6fa85d8f9	unix: Switch stack limit check to new cstack API. ... Necessary to pass CI when testing the V2 preview APIs.

Jim Mussared	557d31ed2c	py/objint: Try to convert big-int back to small-int after binary op. ... Before this change, long/mpz ints propagated into all future calculations, even if their value could fit in a small-int object. With this change, the result of a big-int binary op will now be converted to a small-int object if the value fits in a small-int. For example, a relatively common operation like `x = a * b // c` where a,b,c all small ints would always result in a long/mpz int, even if it didn't need to, and then this would impact all future calculations with x. This adds +24 bytes on PYBV11 but avoids heap allocations and potential surprises (e.g. `big-big` is now a small `0`, and can safely be accessed with MP_OBJ_SMALL_INT_VALUE). Performance tests are unchanged on PYBV10, except for `bm_pidigits.py` which makes heavy use of big-ints and gains about 8% in speed. Unix coverage tests have been updated to cover mpz code that is now unreachable by normal Python code (removing the unreachable code would lead to some surprising gaps in the internal C functions and the functionality may be needed in the future, so it is kept because it has minimal overhead).

Felix Dörre	b802f0f8ab	extmod/modtls: Move the native ssl module to tls. ... The current `ssl` module has quite a few differences to the CPython implementation. This change moves the MicroPython variant to a new `tls` module and provides a wrapper module for `ssl` (in micropython-lib). Users who only rely on implemented comparible behavior can continue to use `ssl`, while users that rely on non-compatible behavior should switch to `tls`. Then we can make the facade in `ssl` more strictly adhere to CPython. Signed-off-by: Felix Dörre <felix@dogcraft.de>	2024-02-07 12:58:52 +11:00
