- any architecture may explicitely build with qstring make
QSTR_AUTOGEN_DISABLE=1 autogeneration disabled and provide its
own list of qstrings by the standard
mechanisms (qstrdefsport.h).
Note this still needs some work: currently all source files are always
preprocessed no matter which one actually changed, moreover that happens
file by file without any parallellism so builds are painstakingly slow.
- add template rule that converts a specified source file into a qstring file
- add special rule for generating a central header that contains all
extracted/autogenerated strings - defined by QSTR_DEFS_COLLECTED
variable. Each platform appends a list of sources that may contain
qstrings into a new build variable: SRC_QSTR. Any autogenerated
prerequisities are should be appened to SRC_QSTR_AUTO_DEPS variable.
- remove most qstrings from py/qstrdefs, keep only qstrings that
contain special characters - these cannot be easily detected in the
sources without additional annotations
- remove most manual qstrdefs, use qstrdef autogen for: py, cc3200,
stmhal, teensy, unix, windows, pic16bit:
- remove all micropython generic qstrdefs except for the special strings that contain special characters (e.g. /,+,<,> etc.)
- remove all port specific qstrdefs except for special strings
- append sources for qstr generation in platform makefiles (SRC_QSTR)
This script will search for patterns of the form Q(...) and generate a
list of them.
The original code by Pavel Moravec has been significantly simplified to
remove the part that searched for C preprocessor directives (eg #if).
This is because all source is now run through CPP before being fed into
this script.
Small hash tables (eg those used in user class instances that only have a
few members) now only use the minimum amount of memory necessary to hold
the key/value pairs. This can reduce performance for instances that have
many members (because then there are many reallocations/rehashings of the
table), but helps to conserve memory.
See issue #1760.
"" is the correct name of the root directory when mounting a device there
(as opposed to "/"). One can now do os.listdir('/') and open('/abc'), as
well as os.listdir() and open('abc').
