Such as moving files, adding directories and changing the label.

Fixes #1192
|
|
Add option to disable the concurrent write protection
|
|
rename ure, ujson, and uerrno to re, json, and errno
|

This allows writing to the filesystem from the host computer and
CircuitPython by increasing the risk of filesystem corruption.

Fixes #1529

MICROPY_PY_URE_MATCH_SPAN_START_END is used to enable the functionality
since it's similar.
|
|
Fix MicroPython #3176
Handle escape sequences inside regular expressions. This adds
handling for \a, \b, \f, \n, \r, \v and \\.

This feature is controlled at compile time by MICROPY_PY_URE_SUB, disabled
by default.
Thanks to @dmazzella for the original patch for this feature; see #3770.

This fixes a large number of crashes on malformed inputs.

Commit 95e70cd0ea6d 'time: Use 1970 epoch' changed epoch for the time
module, but not for other users. This patch does the same for the only
other core timeutils user: extmod/vfs_fat.c:fat_vfs_stat().
Other timeutils users: cc3200, esp8266 and stm32, are not changed.
Ports that don't use long ints, will still get wrong time values from
os.stat().

This saves code space in builds which use link-time optimization.
The optimization drops the untranslated strings and replaces them
with a compressed_string_t struct. It can then be decompressed to
a c string.
Builds without LTO work as well but include both untranslated
strings and compressed strings.
This work could be expanded to include QSTRs and loaded strings if
a compress method is added to C. Its tracked in #531.

* Fix finding translations with escaped characters.
* Add back \r to translations since its needed by screen.

With this patch objects are only checked that they have the stream protocol
at the start of their use as a stream, and afterwards the efficient
mp_get_stream() helper is used to extract the stream protocol C methods.
|
|
Functionality is unchanged.

This patch changes dupterm to call the native C stream methods on the
connected stream objects, instead of calling the Python readinto/write
methods. This is much more efficient for native stream objects like UART
and webrepl and doesn't require allocating a special dupterm array.
This change is a minor breaking change from the user's perspective because
dupterm no longer accepts pure user stream objects to duplicate on. But
with the recent addition of uio.IOBase it is possible to still create such
classes just by inheriting from uio.IOBase, for example:
import uio, uos
class MyStream(uio.IOBase):
def write(self, buf):
# existing write implementation
def readinto(self, buf):
# existing readinto implementation
uos.dupterm(MyStream())

These are not exported to anyone anyway.

Via the config value MICROPY_PY_UHASHLIB_SHA256. Default to enabled to
keep backwards compatibility.
Also add default value for the sha1 class, to at least document its
existence.
|
|
Makes the code much more readable by reducing the number of #ifdefs and
keeping related functions close.
|
|
For consistency with other modules, and to help avoid clashes with the
actual underlying functions that do the hashing (eg
crypto-algorithms/sha256.c:sha256_update).

Following other C-level protocols, this VFS protocol is added to help
abstract away implementation details of the underlying VFS in an efficient
way. As a starting point, the import_stat function is put into this
protocol so that the VFS sub-system does not need to know about every VFS
implementation in order to do an efficient stat for importing files.
In the future it might be worth adding other functions to this protocol.

This VFS component allows to mount a host POSIX filesystem within the uPy
VFS sub-system. All traditional POSIX file access then goes through the
VFS, allowing to sandbox a uPy process to a certain sub-dir of the host
system, as well as mount other filesystem types alongside the host
filesystem.
|
|
So they don't clash with other VFS implementations.

If mbedtls_ctr_drbg_seed() is available in the mbedtls bulid then so should
be mbedtls_entropy_func(). Then it's up to the port to configure a valid
entropy source, eg via MBEDTLS_ENTROPY_HARDWARE_ALT.
|
|
Otherwise the "sock" member may have an undefined value if wrap_socket
fails with an exception and exits early, and then if the finaliser runs it
will try to close an invalid stream object.
Fixes issue #3828.
