Default interface is STA (or AP if available and STA is unavailable).
An interface can also be specified in ::begin() by its IP address.
MDNS will not cross interfaces (there is currently no notion of "bridged interfaces")
Multiple instances should be working, this is not tested in this commit.
* Fix device test environment variables
Device tests were not connecting properly to WiFi because the
environment variables were not set when WiFi.connect was called.
This would result in tests sometimes working *if* the prior sketch run
on the ESP saved WiFi connection information and auto-connect was
enabled. But, in most cases, the tests would simply never connect to
any WiFi and fail.
getenv() works only after BS_RUN is called (because BS_RUN handles the
actual parsing of environment variables sent from the host).
Add a "pretest" function to all tests which is called by the host test
controller only after all environment variables are set. Move all
WiFi/etc. operations that were in each separate test's setup() into it.
So the order of operations for tests now is:
ESP: setup()
-> Set serial baud
-> Call BS_RUN()
HOST: Send environment
Send "do pretest"
ESP: pretest()
-> Set Wifi using env. ariables, etc. return "true" on success
HOST: Send "run test 1"
ESP: Run 1st test, return result
HOST: Send "run test 2"
ESP: Run 2nd test, return result
<and so forth>
If nothing is needed to be set up, just return true from the pretest
function.
All tests now run and at least connect to WiFi. There still seem to be
some actual test errors, but not because of the WiFi/environment
variables anymore.
* Remove unneeded debug prints
* Silence esptool.py output when not in V=1 mode
Esptool-ck.exe had an option to be silent, but esptool.py doesn't so the
output is very chatty and makes looking a the run logs hard (60 lines
of esptool.py output, 3 lines of actual test reports).
Redirect esptool.py STDOUT to /dev/null unless V=1 to clear this up.
* Speed up builds massively by removing old JSON
arduino-builder checks the build.options.json file and then goes off and
pegs my CPU at 100% for over a minute on each test compile checking if
files have been modified.
Simply deleting any pre-existing options.json file causes this step to
be skipped and a quick, clean recompile is done in siginificantly less
time.
* Enable compile warnings, fix any that show up
Enable all GCC warnings when building the tests and fix any that came up
(mostly signed/unsigned, unused, and deprecated ones).
* Fix UMM_MALLOC printf crash, umm_test
Printf can now handle PROGMEM addresses, so simplify and correct the
debug printouts in umm_info and elsewhere.
* scheduled function: replacing new by malloc needs to initialize complex members
Functional was not initialized because of malloc() instead of new.
First assignment calls destructor on initial value which was not constructed (->frozen,wdt).
Fixes#6220
MklittleFS had different configuration options which affected small
files and could result in crashes or corruption on upload.
Update mklittlefs tool to one that matches the config of the current
library.
You will need to re-run tools/get.py to get the new tool version if you
are running from Git.

When in basic SSL mode, don't include ciphers for EC for the server by
replacinf the BearSSL "support everything" init call with our own
version which obeys the requested BASIC_SSL.
Saves ~46KB on TLS servers, about the same as basic SSL saves for
clients.
Undo the BearSSL RODATA->PROGMEM changes because there are some bad
performance regressions in EC server operations which can result in
timeouts and WDTs.
Keep the shrunked bearssl.a library as that is orthogonal to the PROGMEM
changes.
Rewrite all the integer math operations with const input parameters to
use PROGMEM properly (pgm_read_xx or memcpy_P), and move all the EC
order and generators and SHA OIDs to PROGMEM.
This frees around 1.2KB of heap for any SSL applications.
Also delete unneeded objects from the bearssl.a library to shrink the
GIT repo size.
Supercedes #6027
Make SSO more generic by keeping track of its length explicitly,
allowing for embedded \0s to exist in the String (just like the non-SSO
ones).
Use memmove/memcpy_P when we know the length of a string to save CPU
time.
Add tests to inject \0s in a String to ensure it is still working as
designed.

__This is a breaking change, but the header and example did warn
everyone that this API was in flux due to the incompatible SD and SPIFFS
File implementations.__
BearSSL CertStores now simply need a filesystem and the names of the
data (generated on-chip) and archive (uploaded by user) files on it.
No more need to roll your own virtual CertStoreFile class.
Update the library, examples, and device test.
Fixes#6082
Add an info64() call which returns used and total sizes as 64 bit
quantities. A default wrapper that just copies the 32-bit values is
included for LittleFS/SPIFFS which can't hit those capacities.
As found by @mhightower83, umm_malloc was placed in flash during the
.c->.cpp conversion because of a missed linker change.
Adjust the link script to the new name .cpp
Move additional constants to flash and use _P/pgm_read routines to
access them. Minimal runtime impact, but remove variables from RODATA
and gives addition 484 bytes of heap to SSL applications.
Fixes#6005
On return from a BSSL call, check that the last element of the stack is
still untouched. If it is modified, print an error and abort().
Will catch problems like #6143 many times with an informative error
message instead of corrupting the heap and having a random crash
sometime later.
* std::bind has issues with type inference, use lambdas whereever possible.
* Fix indentation.
* More descriptive placeholder name in lambda expression
* Use formal argument names for remaining currying placeholders
* Add LittleFS as internal flash filesystem
Adds a LittleFS object which uses the ARMmbed littlefs embedded filesystem,
https://github.com/ARMmbed/littlefs, to enable a new filesystem for onboard
flash utilizing the exact same API as the existing SPIFFS filesystem.
LittleFS is built for low memory systems that are subject to random power
losses, is actively supported by the ARMmbed community, supports directories,
and seems to be much faster in the large-ish read-mostly applications I use.
LittleFS, however, has a larger minimum file allocation unit and does not do
static wear levelling. This means that for systems that need many little
files (<4K), have small SPIFFS areas (64K), or which have a large static
set of files covering the majority of flash coupled with a frequently
updated set of other files, it may not perform as well.
Simply replace SPIFFS.begin() with LittleFS.begin() in your sketch,
use LittleFS.open in place of SPIFFS.open to open files, and everything
else just works thanks to the magic of @igrr's File base class.
**LITTLEFS FLASH LAYOUT IS INCOMPATIBLE WITH SPIFFS**
Since it is a completely different filesystem, you will need to reformat
your flash (and lose any data therein) to use it. Tools to build the
flash filesystem and upload are at
https://github.com/earlephilhower/arduino-esp8266littlefs-plugin and
https://github.com/earlephilhower/mklittlefs/ . The mklittlefs tool
is installed as part of the Arduino platform installation, automatically.
The included example shows a contrived read-mostly example and
demonstrates how the same calls work on either SPIFFS.* or LittleFS.*
Host tests are also included as part of CI.
Directories are fully supported in LittleFS. This means that LittleFS
will have a slight difference vs. SPIFFS when you use
LittleFS.openDir()/Dir.next(). On SPIFFS dir.next()
will return all filesystem entries, including ones in "subdirs"
(because in SPIFFS there are no subdirs and "/" is the same as any
other character in a filename).
On LittleFS, dir.next() will only return entries in the directory
specified, not subdirs. So to list files in "/subdir/..." you need
to actually openDir("/subdir") and use Dir.next() to parse through
just those elements. The returned filenames also only have the
filename returned, not full paths. So on a FS with "/a/1", "/a/2"
when you do openDir("/a"); dir.next().getName(); you get "1" and "2"
and not "/a/1" and "/a/2" like in SPIFFS. This is consistent with
POSIX ideas about reading directories and more natural for a FS.
Most code will not be affected by this, but if you depend on
openDir/Dir.next() you need to be aware of it.
Corresponding ::mkdir, ::rmdir, ::isDirectory, ::isFile,
::openNextFile, and ::rewind methods added to Filesystem objects.
Documentation has been updated with this and other LittleFS information.
Subdirectories are made silently when they do not exist when you
try and create a file in a subdir. They are silently removed when
the last file in them is deleted. This is consistent with what
SPIFFS does but is obviously not normal POSIX behavior. Since there
has never been a "FS.mkdir()" method this is the only way to be
compatible with legacy SPIFFS code.
SPIFFS code has been refactored to pull out common flash_hal_* ops
and placed in its own namespace, like LittleFS.
* Fix up merge blank line issue
* Merge in the FSConfig changs from SDFS PR
Enable setConfig for LittleFS as well plys merge the SPIFFS changes
done in the SDFS PR.
* Fix merge errors
* Update to use v2-alpha branch
The V2-alpha branch supports small file optimizations which can help
increase the utilization of flash when small files are prevalent.
It also adds support for metadata, which means we can start adding
things like file creation times, if desired (not yet).
* V2 of littlefs is now in upstream/master
* Update test to support non-creation-ordered files
In a directory, the order in which "readNextFile()" will return a name
is undefined. SPIFFS may return it in order, but LittleFS does not as
of V2. Update the test to look for files by name when doing
readNextFile() testing.
* Fix LittleFS.truncate implementation
* Fix SDFS tests
SDFS, SPIFFS, and LittleFS now all share the same common set of tests,
greatly increasing the SDFS test coverage.
* Update to point to mklittlefs v2
Upgrade mklittlefs to V2 format support
* Remove extra FS::write(const char *s) method
This was removed in #5861 and erroneously re-introduced here.
* Minimize spurious differences from master
* Dramatically reduce memory usage
Reduce the program and read chunk sizes which impacts performance
minimally but reduces per-file RAM usage of 16KB to <1KB.
* Add @d-a-v's host emulation for LittleFS
* Fix SW Serial library version
* Fix free space reporting
Thanks to @TD-er for discovering the issue
* Update littlefs to latest upstream
* Remove sdfat version included by accident
* Update SDFAT to include MOCK changes required
* Update to include SD.h test of file append
* add regular scheduled functions, now also callable on `yield()`
added bool schedule_function_us(std::function<bool(void)> fn, uint32_t repeat_us)
lambda must return true to be not removed from the schedule function list
if repeat_us is 0, then the function is called only once.
Legacy schedule_function() is preserved
This addition allows network drivers like ethernet chips on lwIP to be regularly called
- even if some user code loops on receiving data without getting out from main loop
(callable from yield())
- without the need to call the driver handling function
(transparent)
This may be also applicable with common libraries (mDNS, Webserver, )
-Expose HTTP Digest authentication with H1 hash as the argument
-Preserved HTTP authentication with username/password arguments
-Added a public static function for generating the H1 hash
-Created an example of how to use this called HttpHashCredAuth.ino
