Jeff Epler 2fb5eb3b11 extmod/re1.5: Check and report byte overflow errors in _compilecode.
The generated regex code is limited in the range of jumps and counts, and
this commit checks all cases which can overflow given the right kind of
input regex, and returns an error in such a case.

This change assumes that the results that overflow an int8_t do not
overflow a platform int.

Closes: #7078

Jeff Epler ab5eb86118 raspberrypi: implement os.urandom
Since the datasheet cast some doubt on the strength of the "rosc_hw->randombit",
I use the SHA256 hash function to create a high quality random seed
from random values of uncertain entropy, as well as to generate a sequence
of random values from that seed using SHA256 as a cryptographically-secure
random number generator.

In practice, it produces over 100kB/s of random data which does not
have any gross problems according to _PractRand_.

Jeff Epler 9d8be648ee ulab: Update to release tag 1.1.0
Disable certain classes of diagnostic when building ulab.  We should
submit patches upstream to (A) fix these errors and (B) upgrade their
CI so that the problems are caught before we want to integrate with
CircuitPython, but not right now.

Speed up JSON parsing with readinto
Get a chunk of data from readinto instead of a single byte. This
speeds up the parsing by reducing the number of function calls.

Unify iMX flash config and add Metro M7 1011
This unifies the flash config to the settings used by the Boot ROM.
This makes the config unique per board which allows for changing
quad enable and status bit differences per flash device. It also
allows for timing differences due to the board layout.

This change also tweaks linker layout to leave more ram space for
the CircuitPython heap.

Jeff Epler 9b8df7f635 Upgrade ulab
This version
 * moves source files to reflect module structure
 * adds inline documentation suitable for extract_pyi
 * incompatibly moves spectrogram to fft
 * incompatibly removes "extras"

There are some remaining markup errors in the specific revision of
extmod/ulab but they do not prevent the doc building process from
completing.

warriorofwire d8491f3176 ujson: back out overeager loads() change; only change load() 2020-05-10 21:56:01 -07:00
warriorofwire eb3d5fa453 ujson: do not eat trailing whitespace
Ujson should only worry about whitespace before JSON.  This becomes apparent when you are using MP stream protocol to read directly from input buffers.

When you attempt to read(1) on a UART (and possibly other protocols) you have to wait for either the byte or the timeout.

Fixes:
- Waiting for a timeout after you have completed reading a correct and complete JSON off the input.
- Raising an OSError after reading a correct and complete JSON off the input.
- Eating more data than semantically owned off the input buffer.
- Blocking to start parsing JSON until the entire JSON body has been loaded into a potentially large, contiguous Python object.

Code you would write before:
```
line = board_busio_uart_port.read_line()
json_dict = json.loads(line)
```
or reaching for fixed buffers and swapping them around in Python.

Code that did not work before that does now:
```
json_dict = json.load(board_busio_uart_port)
```

- This removes the need for intermediate copies of data when reading JSON from micropython stream protocol inputs.
- It also increases total application speed by parsing JSON concurrently with receiving on boards that read from UART via DMA.
- It simplifies code that users write while improving their apps.
