Commit d96cfd13e3 introduced a regression in
testing for bool objects, that such objects were in some cases no longer
recognised and bools, eg when using mp_obj_is_type(o, &mp_type_bool), or
mp_obj_is_integer(o).
This commit fixes that problem by adding mp_obj_is_bool(o). Builds with
MICROPY_OBJ_IMMEDIATE_OBJS enabled check if the object is any of the const
True or False objects. Builds without it use the old method of ->type
checking, which compiles to smaller code (compared with the former
mentioned method).
Fixes#5538.
When threads and the GIL are enabled, then the qstr mutex is not needed.
The qstr_mutex field is never used in this case because of:
#if MICROPY_PY_THREAD && !MICROPY_PY_THREAD_GIL
#define QSTR_ENTER() mp_thread_mutex_lock(&MP_STATE_VM(qstr_mutex), 1)
#define QSTR_EXIT() mp_thread_mutex_unlock(&MP_STATE_VM(qstr_mutex))
#else
#define QSTR_ENTER()
#define QSTR_EXIT()
#endif
So, we can completely remove qstr_mutex everywhere when MICROPY_PY_THREAD
&& !MICROPY_PY_THREAD_GIL.
When threads and the GIL are enabled, then the GC mutex is not needed. The
gc_mutex field is never used in this case because of:
#if MICROPY_PY_THREAD && !MICROPY_PY_THREAD_GIL
#define GC_ENTER() mp_thread_mutex_lock(&MP_STATE_MEM(gc_mutex), 1)
#define GC_EXIT() mp_thread_mutex_unlock(&MP_STATE_MEM(gc_mutex))
#else
#define GC_ENTER()
#define GC_EXIT()
#endif
So, we can completely remove gc_mutex everywhere when MICROPY_PY_THREAD
&& !MICROPY_PY_THREAD_GIL.
Some parts of code have been aligned to increase readability. In general
'' instead of "" were used wherever possible to keep the same convention
for entire file. Import inspect line has been moved to the top according
to hints reported by pep8 tools. A few extra spaces were removed, a few
missing spaces were added. Comments have been updated, mostly in
"read_dfu_file" function. Some other comments have been capitalized and/or
slightly updated. A few docstrings were fixed as well. No real code
changes intended.
Translate common Ctrl-Left/Right/Delete/Backspace to the EMACS-style
sequences (i.e. Alt key based) for forward-word, backward-word, forwad-kill
and backward-kill. Requires MICROPY_REPL_EMACS_WORDS_MOVE to be defined so
the readline implementation interprets these.
Prior to this commit, if the flash filesystem was not formatted then it
would error: "AttributeError: 'FlashBdev' object has no attribute 'mount'".
That is due to it not being able to detect the filesystem on the block
device and just trying to mount the block device directly.
This commit fixes the issue by just catching all exceptions. Also it's not
needed to try the mount if `flashbdev.bdev` is None.
Can be used where mp_obj_int_get_checked() will overflow due to the
sign-bit solely. This returns an mp_uint_t, so it also verifies the given
integer is not negative.
Currently implemented only for mpz configurations.
This function is called often and with immediate objects enabled it has
more cases, so optimise it for speed. With this optimisation the runtime
is now slightly faster with immediate objects enabled than with them
disabled.
