1. ref_clock used in unit tests occasionally produces time off by ~100
microseconds shortly after being started. Add a delay to let
ref_clock stabilise, until the cause is found.
2. Reduce roundoff error accumulation which would occasionally cause
the test to fail, by choosing an overflow value which can be divided
by APB frequency.
3. Move time sampling part of the test into an IRAM function to
reduce variations due to cache behavior.
4. Remove calculation of "standard deviation" in the test, as what was
calculated was not actually standard deviation, and it did not add any
useful information.
Previously when HashList was removing items, HashListBlocks were
removed lazily. This resulted in empty HashListBlocks dangling around
in full pages, even when all items have been erased. These blocks
would only be deleted when NVS was re-initialized
(nvs_flash_deinit/nvs_flash_init).
This change does eager cleanup instead, based on the code from
@negativekelvin offered in
https://github.com/espressif/esp-idf/issues/1642#issuecomment-367227994.
Closes https://github.com/espressif/esp-idf/issues/1642.
Added APIs :
* httpd_resp_send_err() : for sending HTTP error responses for error codes given by httpd_err_code_t. It uses TCP_NODELAY option to ensure that HTTP error responses reach the client before socket is closed.
* httpd_register_err_handler() : for registering HTTP error handler functions of type httpd_err_handler_func_t.
The default behavior, on encountering errors during processing of HTTP requests, is now to send HTTP error response (if possible) and close the underlying socket. User configurable handlers can be used to override this behavior for each error individually (except for 500 Internal Server Error).
Also fixed some typos.
Closes https://github.com/espressif/esp-idf/issues/3005
fix 3 bugs:
1. do BLE connect (both of slave and master), it mgiht cause crash due to there's much interrupts happens effect ble code running, for example, wifi run on the same core as bluetooth controller and wifi run throughtput test.
2. do BLE scan stop or adv stop or connection stop, it might cause ASSERT or crash due to memory corrupted in controller memory poll.
3. minor bug fix, not really effect bluetooth.
The bug will cause memory corrupted (the largest range is from 0x3ffc0000 ~ 0x3ffc8000),
some strange error will happen, like IllegalInstruction, LoadProhibited and .etc.
docs: This is a quick reference of more than a dozen and-ons and extensions prepared over the last two years to add contents, improve look & feel and cut on maintenance of the ESP-IDF documentation.
