I like to use local makefile overrides, in the file GNUmakefile
(or, on case-sensitive systems, makefile) to set compilation choices.
However, writing
TRANSLATION := de_DE
include Makefile
did not work, because py.mk would override the TRANSLATION := specified
in an earlier part of the makefiles (but not from the commandline).
By using ?= instead of := the local makefile override works, but when
TRANSLATION is not specified it continues to work as before.
Instead of unrolling the code 16 times, unroll it 4 times and loop
over it 4 times. This gives the same 16 iterations, but at an expense
of less flash space.
This ensures that only the translate("") alternative that will be used
is seen after preprocessing. Improves the quality of the Huffman encoding
and reduces binary size slightly.
Also makes one "enhanced" error message only occur when ERROR_REPORTING_DETAILED:
Instead of the word-for-word python3 error message
"Type object has no attribute '%q'", the message will be
"'type' object has no attribute '%q'". Also reduces binary size.
(that's rolled into this commit as it was right next to a change to
use the preprocessor for MICROPY_ERROR_REPORTING)
Note that the odd semicolon after "value_error:" in parsenum.c is necessary
due to a detail of the C grammar, in which a declaration cannot follow
a label directly.
This makes a more useful display on the portrait magtag, allowing 21
characters across instead of just 18. There are 20 full rows of text,
instead of 21. The total number of characters increases slightly from 378
to 420.
For comparison, the Commodore VIC 20 had 22 rows of 23 characters for a
total of 506 characters. :-P
This reclaims over 1kB of flash space by simplifying certain exception
messages. e.g., it will no longer display the requested/actual length
when a fixed list/tuple of N items is needed:
if (MICROPY_ERROR_REPORTING == MICROPY_ERROR_REPORTING_TERSE) {
mp_raise_ValueError(translate("tuple/list has wrong length"));
} else {
mp_raise_ValueError_varg(translate("requested length %d but object has length %d"),
(int)len, (int)seq_len);
Other chip families including samd51 keep their current error reporting
capabilities.
While trying to debug #3572, I noticed that I would frequently break in
the midst of gettimeofday and that the routine get_adjusted_boot_time
had to take and release locks. Furthermore, we don't want "adjusted"
boot time, which could go forwards or backwards depending on the
adjustment (such as setting the clock used by gettimeofday() to the network
time)
Before, there were two problems:
* Even if a pulsein was never constructed, supervisor_disable_tick
would occur during restart. This could cancel out a supervisor_enable_tick
from someplace else, with unexpected results.
* If two or more pulseins were constructed, each one would enable ticks,
but only the last one deinited (or the reset routine) would disable,
leaving ticks running indefinitely.
In my testing, it seemed that this led to the board sometimes stopping when
it should have auto-reloaded.
