* Add HTTP_HEAD to HTTPMethod
* Parse the HTTP_HEAD variant of HTTPMethod from a method string
* Add HTTP_HEAD to the ESP8266WebServer constants
* Skip sending the content of the response if the HTTP method is HEAD method
* Convert the HTTP status code 418 to string
This status code is an easter egg from the IETF and is described in
[RFC2324](https://tools.ietf.org/html/rfc2324#section-2.3.2)
- Add createPermanentConnections argument to attemptAutoEncryptingTransmission method.
- Reduce risk of misinterpreting acks by adding check for ack sender MAC.
- Reduce _encryptionRequestTimeoutMs from 500 ms to 300 ms since this should give enough (100 %) margin to the level where problems start appearing (150 ms timeout) and also save a lot of time in case of request failure.
- Improve comments.
A typo was present in several ifdefs which would allow a server to negotiate
an EC connection even when in basic SSL mode. When this happened, a crash
would occur (since there were no EC or advanced AES modes installed).
Fix the typo, fixes#6397
Fixes#6066
Preserve any existing sample rate for the I2S unit when performing an
`i2s_begin`. If nothing has ever been set, default to 44.1KHz as
before.
* Add a FS::check() optional method
Fixes#2634
Expose any low-level filesystem check operations for users, and add
documentation on this and the gc() methods.
* Update doc w/more gc() info and link
* Update LittleFS to current project head
Several bugfixes noted in the LittleFS added:
https://github.com/ARMmbed/littlefs/commits/master
* Also update SdFat to latest upstream head
Also adds a delay(0) every 5000 fat clusters examined to avoid WDT
errors on highly fragmented FAT filesystems.

The Arduino WiFiClient object allows sending the same packet to all
connected clients of a WiFiServer. In their implementation it may make
sense, but on the 8266 with things like SSL it doesn't.
Update the docs to note that WiFiServer::write() is a no-op, and that
the app should use the WiFiCliebnt::write() on all connected clients as
appropriate.
Fixes#2567
Allow the web server to send plain C strings instead of requring they be
encapsulated inside a String class object. Saves memory vs. having to
convert C strings to Strings (i.e. duplication of data), overloads on
the efficient sendContent_P(char*) methods.
Looking at other projects, they're all building using gnu extensions
(-std=gnu++11). We're already embedding gnu-specific pragmas for
compile options, so I see no reason not to fall in line w/others on
this.
Fixes#4639
Default mode (no exceptions) will no longer use the stdc++ library new
allocator when there is not enough memory. Instead, it will return
nullptr. This is the pre-exceptions-available behavior (2.5.0 and
earlier).
When exceptions are enabled, use the real new and throw exceptions that
can be caught at higher levels, or which will crash the app with an
uncaught exception if they're not handled.
Update to #6309
Fixes#2090
The Updater checks that an update isn't already in progress on ::begin,
but when an error happens in the middle of an upload it's impossible to
actually reset this flag w/o a reboot.
Reset the state members (esp. _size) on any error condition so
that you can restart the transfer with a new ::begin. Any error
condition is fatal, anyway, so there is no reason not to clear the
current state at that point.
The SPIFFS config object was defined in FS.h in its own namespace, but
is not made easily available like other SPIFFS and FS objects because of
a missing `using` statement. Add it in FS.h
Fixes#6322
* Upgrade to 2.5.0-4 toolchain w/improved pgm_read_x
Rebuild the entire toolchain (including standard libraries) with the
latest pgm_read_xxx headers included (which fix unaligned dword reads
from progmem and run faster/smaller, and a pgm_read_byte change which
removes an instruction on each read saving flash).
Pull in latest bearssl while we're at it, too, which speeds up EC
handshakes and reduced ROM usage, too.
* Fix C++ exceptions
Exception code now only does 32b aligned reads from progmem to access
the eh_table (some via -mforce-l32, some via hand-inserted pgm_read_x
macros).
Fixes#6151Fixes#6305Fixes#6198
Fixes#6068
Drop from the tools key all version:"1.20.0-26-gb404fb9" entries (which
were pre-2.0.0 and whose entry in platform versions was deleted on last
release).
* workaround when an exceptin occurs while in an ISR
* tuning for gdb
* remove dead code and rename defines/variables
* per reviews: naming, handle "unhandled return" case
* fix reset message
* Created empty method
* Changed method name from "empty" to "isEmpty". Created a new method to empty a string
* Changed method name from "empty" to "clear".
Cleans up all warnings seen w/GCC 9.1 to allow it to track the main
branch more easily until 3.x.
Does not include Ticker.h "fix" of pragmas around a function cast we're
doing that GCC9 doesn't like, that will be addressed separately and
maybe only in the 3.0 branch.
Does not include GDB hook fix, either, because the pragmas required
to disable the GCC9.1 warnings don't exist in 4.8 at all.
* Add a dump of received FP and CERT when in debug mode
To simplify BearSSL debugging, print the received FP (when it doesn't
match the expected) and the binary certificate (always), when in debug
mode.
* Add documentation section on FP mismatch in rare instances.
Without this the compiler may use memory references loaded to registers before the fence, in computation within the fence. These values could have changed before xt_rsil()
(critical section start) was called.
Note: this is needed to stop the compiler from reordering instructions at the critical section boundary.
* Prepare signing before sketch is compiled
This makes the right value available in ARDUINO_SIGNING in the sketch.
* Remove unnecessary .1s and fix packager script
- Add HelloEspnow.ino example to demonstrate the ESP-NOW mesh backend features.
- Deprecate the ESP8266WiFiMesh class in favour of the new ESP-NOW and TCP/IP backends.
- Update the TCP/IP mesh backend to use the new lwIP version preprocessor flag and remove obsolete preprocessor flags.
* enable by default latest 2.2.x firmware, including fixed espnow
* LittleFS: avoid crash when FS size is 0
* flash size defaults: 1M for generic board, not empty FS for all
