* Put longer string literals into PROGMEM
* Use Flash Strings for Debug output
This is hopefully very infrequently used, so it shouldn't
be in main memory.
* Align to latest EspSoftwareSerial release - nothing ESP8266 specific, but drifting versions otherwise makes life hard for users.
* ghostl array compatibility: aggregate initialization, no implicit cast to T*.
* Remove duplicated sha1 implementation (Fixes#6568)
The Hash library had its own copy of a loop-unrolled sha1 implementation
adding a large code footprint for no good reason, as there are several
sha1 implementations already in tree (one in NONOS-SDK as well as one
in bearssl). Switching to the bearssl one is straightforward and removes
about 3kb of code size overhead.
Also cleanup some obvious inefficiencies (copy by value, string
summing, no reservation causing repeated reallocations) in the
implementation.
* Remove overload variants for sha1(...) that accept nonconst data
The data is always remaining unmodified, so non-const overloads
are confusing and redundant. Also optimize the hexify variant
a bit more.
The function accidentally compared the current location instead
of the passed in (new) location, which didn't match intended
logic and the code comment.
* Add EEPROM debug printouts, error check to example
Add debug printouts when EEPROM calls fail, even if the API doesn't
allow returning a success/failure code.
Adds error checking to the example to make it explicit that when you
call EEPROM::commit(), you need to look at the result code in your code.
Fixes#6551 , or would fix it if there was error checking in the MCVE.
* Clarify example error message
When the FS_END was adjusted to end on a full block (i.e. rounded down)
to avoid filesystem issues, but _FS_end was changed. The EEPROM library
used _FS_end to implicitly calculate the start of the EEPROM data, so
this means after the _FS_end fix, EEPROM data written with prior
releases would "disappear."
Avoid the issue by explicitly calculating the EEPROM start location in
the linker, using the same formula as prior release.
Fixes#6531
* Allow SPIFFS update via ESP8266HTTPUpdateServer
This adds capability to update the SPIFFS image via
the same mechansism as firmware in the
ESP8266HTTPUpdateServer.
It does not provide any dependency or linkage between
firmware and spiffs image updating; they are each taken
on their own, each followed by a reboot.
(I wrote this before seeing the other PR for similar
functionality; I like this a bit better, becaue it uses
the available SPIFFS size, and does not hide magic numbers
(U_SPIFFS) in the html...)
(It also cleans up a stray \n from commit ace0622)
* A simple filter
* Review https://github.com/esp8266/Arduino/pull/3234#pullrequestreview-37773153
* Including suggestions for mobile first #3961
* SPIFFS rennamed to FS
* including comments from @earlephihower
* button renaming
* missing #include for LittleFS
* generic names as suggested by @d-a-v
* Fix WiFiClientSecure::available blocking
Added a check of WiFiClient::availableForWrite to prevent blocking writes when the _run_until blocking flag is false
* change availForWrite from int to size_t
* add timeout to _run_until loop
fixes#6464
* use polledTimeout with _timeout millis
* mDNS debug option + AP address is used by default when STA is also present
* mDNS: store network interface, checking it is up
* igmp: force on selected interface (avoid crash *sometimes*)
* fix for all lwip2 ipv4 ipv6 & lwip1
* mdns: IPAddress is not needed to reference associated interface
* mdns: debug: fix print warnings
* emulation: add ets_strncpy
* emulation: truly emulate AddrList (remove fake one)
* Move all scripts and documentation to Python3
Python 2 EOL is Jan 1, 2020. Migrate scripts to run under Python 3.
Under Windows, we're already running Python 3.7, by dumb luck. The
oddness is that the Windows standalone executable for Python 3 is called
"python" whereas under UNIX-like OSes it's called "python3" with
"python" always referring to the Python 2 executable. The ZIP needs to
be updated to include a Python3.exe (copy of Python.exe) so that we can
use the same command lines under Linux and Windows, and to preserve my
sanity.
Fixes#6376
* Add new Windows ZIP with python3.exe file
* Sort options in boards.txt generation for repeatability
The order of the board opts dict changes depending on the Python version
and machine, so sort the options before printing them to get a stable
ordering.
* Re-add Python2 compatibility tweaks
Most scripts can run as Python 2 or Python 3 with minimal changes, so
re-add (and fix, as necessary) compatibility tweaks to the scripts.
* Per @earlephilhower suggestion
* Hints from @earlephilhower
* Namespace BearSSL in core "feels" wrong - using catch-all esp8266 instead.
* After review remarks by @earlephilhower
This PR stops the 1ms-delay loop also when a tcp error occurs (previously this was done only when tcp had just connected or a write/send had succeeded).
The tcp error can be any, in this case with pubsubclient it is "connection refused" after the mqtt server disappeared and pubsubclient tries to reconnect.
* 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)
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
* 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.
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.
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.
* 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
* Add support for newer mobile OS changes.
Took me quite a while to figure this out, but according to this issue (https://github.com/espressif/arduino-esp32/issues/1037), in order to get a captive notification to show or the popup to open, the DNS server must resolve to a public IP. It will not work with a pivate one (e.g. 192.168.4.1).
On Android, a notification ("Register with Network") is displayed in top left notification bar.
On IOS, the login popup is displayed.

Apply most compatible changes needed to get the core compiling under GCC
7.2 to the main gcc 4.8 tree to ease porting for 3.0.0.
Update pgmspace.h with corrected and optimized unaligned pgm_read
macros. Now pgm_read_dword in the unaligned case gives proper results
even if optimization is enabled and is also written in assembly and only
1 instruction longer than the pgm_read_byte macro (which also has been
optimized to reduce 1 instruction). These changes should marginally
shrink code and speed up flash reads accordingly.
The toolchain should/will be rebuilt at a later time with this
optimization to ensure it's used in the libc.a/etc. files.
After verifying that they really were spurious, clean up the warnings
that gcc -wextra reports, except for LeaMDNS.
Upgrade GCC to gcc-7 for host builds
* TCP connect and send delay fix
Implement early exit as connection established or data already sent.
(Previous implementation was exiting only on timeout expired)
