The packages JSON file which includes the boards, tools, etc. and needs to
have consistent formatting to be reproducible. The current boards.txt.py
uses a REGEX to string-replace a bit of it, but that bit has a different
indent than the rest of the file.
Use Python's JSON writer to format the whole file repeatably.
* Add %z and %x to printf backend
%z is a C99 format used for size_t and was not included in any printf.
On the 8266 it's a no-op as size_t==int, so ignore it and things just
work.
%x lowercase support added back in (wasn't present in nano-printf).
* Update to toolchain built newlib, fix link error
Previous commit was a hand build and copy, this one used the full
toolchain and should not include atexit().
Looks like the pgm_read_(32bit) defines were not used in the main core, and
they contained syntax errors when invoked due to some bad bracket/parens.
Fix the macros
* Move to PROGMEM aware libc, allow PSTR in printf()
A Newlib (libc) patch is in progress to move the _P functions from inside
Arduino into first-class citizens in libc. This Arduino patch cleans up
code that's been migrated there. Binaries for the new libs are included
because it seems they're part of the Arduino git tree, and should be
replaced with @igrr built ones when/if the Newlib changes are accepted.
Notable changes/additions for Arduino:
Allow for use of PROGMEM based format and parameter strings in all
*printf functions. No need for copying PSTR()s into RAM before printing
them out (transparently saves heap space when using _P functions) and
makes it easier to print out constant strings for applications.
Add "%S" (capital-S) format that I've been told, but cannot verify,
is used in Arduino to specify a PROGMEM string parameter in printfs,
as an alias for "%s" since plain "%s" can now handle PROGMEM.
Optimized the memcpy_P, strnlen_P, and strncpy_P functions to use 32-bit
direct reads whenver possible (source and dest alignment mediated), but
there is still room for improvement in others.
Finally, move several constant arrays from RODATA into PROGMEM and
update their accessors. Among these are the ctype array, ~260 bytes,
mprec* arrays, ~300 bytes, and strings/daycounts in the time
formatting functions, ~200 bytes. All told, sketches will see from
300 to 800 additional RAM heap free on startup (depending on their
use of these routines).
* Fix merge error in #ifdef/#endif
* Fix host test using the newlib generic pgmspace.h
Host tests now use the sys/pgmspace.h for compiles instead of the
ESP8266-specific version.
* Update with rebuilt libraries using latest newlib
* Include binaries built directly from @igrr repo
Rebuild the binaries using a git clone of
https://github.com/igrr/newlib-xtensa

* Fix merge define conflict in c_types.h
* Fix strlen_P misaligned source error
Include fix from newlib-xtensa/fix-strlen branch cleaning up misaligned
access on a non-aligned source string.
* Fix strlen_P and strcpy_P edge cases
Ran the included test suite on ESP8266 tstring.c with the following defines:
#define MAX_1 50
#define memcmp memcmp_P
#define memcpy memcpy_P
#define memmem memmem_P
#define memchr memchr_P
#define strcat strcat_P
#define strncat strncat_P
#define strcpy strcpy_P
#define strlen strlen_P
#define strnlen strnlen_P
#define strcmp strcmp_P
#define strncmp strncmp_P
Uncovered edge case and return value problems in the optimized versions of
the strnlen_P and strncpy_P functions. Corrected.
* Fix memcpy_P return value
memcpy-1.c test suite showed error in return value of memcpy_P. Correct it.
* Fix strnlen_P/strlen_P off-by-4 error
Random crashes, often on String constructors using a PSTR, would occur due
to the accelerated strnlen_P going past the end of the string. Would make
debug builds fail, too (ESP.getVersionString() failure).
Fix to fall through to normal copy on a word that's got a 0 byte anywhere
in it.
* Add device tests for libc functional verification
Add test suite used to debug libc optimized _P functions to the device
tests.
* Rebuild from igrr's repo (same source as prior)
Rebuild .a from igrr's repo at 347260af117b4177389e69fd4d04169b11d87a97
* WIP - add exceptions
* Fix exception to have 0-terminator
* Move some exception constants to TEXT from RODATA
* Remove throw stubs
* Move more exception stuff to ROM
* Enable exceptions in platform.io
* Remove atexit, is duplicated in rebuilt lib
Need to look at the quick-toolchain options, there seems to be a definition
for atexit defined there (libgcc?) that needs to be excised. For now,
remove our local do-nothing copy.
* Update libgcc to remove soft-fp functions
The esp-quick-toolchain generated libgcc.a needed to have the soft-FP routines
that are in ROM removed from it. Remove them in the new esp-quick-toolchain
and update.
* Fix merge typos in Makefile
* Add unhandled exception handler to postmortem
* Return our atexit() handler
* Latest stdc++, minimize exception emercengy area
* Remove atexit from newlib
atexit was defined in newlib strongly, but we also define a noop atexit in core.
Since we never exit, use the core's noop and delete the atexit from libc.a
Updated in esp-quick-toolchain as well.
* Move __FUNCTION__ static strings to PROGMEM
__FUNCTION__ is unlikely to be a timing sensitive variable, so move it to
PROGMEM and not RODATA (RAM) using linker magic.
asserts() now should take no RAM for any strings.
* Clean up linker file, update to latest stdc++
* Update to latest stdc++ which doesn't call strerror
* Update to GCC5.1 exception emergency allocator
Using GCC 5.1's emergency memory allocator for exceptions, much less
space is required in programs which do not use exceptions and when
space is allocated it is managed more efficiently.
* Initial try with new compiler toolchain
* Include newlib built from esp-quick-toolchain
* Update JSON with all new esp-quick-toolchain builds
* Use 64bit Windows compiler on 64bit Windows
* Dump std::exception.what() when possible
When doing the panic on unhandled exceptions, try and grab the
.what() pointer and dump it as part of the termination info.
Makes it easy to see mem errors (std::bad_alloc) or std::runtime_error
strings.
* Use scripted install from esp-quick-toolchain
Makes sure proper libraries and includes are present by using a
scripted installation from esp-quick-install instead of a manual
one.
* Update eqk to remove atexit, fix packaging diff
Using a pluggable architecture, allow updates delivered via the Update
class to be verified as signed by a certificate. By using plugins, avoid
pulling either axTLS or BearSSL into normal builds.
A signature is appended to a binary image, followed by the size of the
signature as a 32-bit int. The updater takes a verification function
and checks this signature using whatever method it chooses, and if it
fails the update is not applied.
A SHA256 hash class is presently implemented for the signing hash (since
MD5 is a busted algorithm).
A BearSSLPublicKey based verifier is implemented for RSA keys. The
application only needs the Public Key, while to sign you can use
OpenSSL and your private key (which should never leave your control
or be deployed on any endpoints).
An example using automatic signing is included.
Update the docs to show the signing steps and how to use it in the
automatic and manual modes.
Also remove one debugging line from the signing tool.
Saves ~600 bytes when in debug mode by moving strings to PMEM
Windows can't run the signing script, nor does it normally have OpenSSL
installed. When trying to build an automatically signed binary, warn
and don't run the python.
* restore definition of ip_addr (=ipv4_addr) when IPv6 is not enabled
* overload IPAddress:operator == and != to avoid ambiguousness
* brings lwIP's INADDR_NONE (which is IPv4 255.255.255.255, suposed to be invalid address but it is)
* inet_aton is a lwIP define, rename Ethernet DNS implementation of this to prevent name collision
that's because IPAddress now includes lwip/inet.h
I recently starting playing around with a few esp8266-01s and tried to use the SSDP libraries to work with Smarthings discovery:
https://docs.smartthings.com/en/latest/cloud-and-lan-connected-device-types-developers-guide/building-lan-connected-device-types/building-the-service-manager.html
on the docs there are example grovy files that do simple service discovery, i was not able to get SSDP to work correctly, though i was able to find some other projects that did (python fauxmo works for alexa, but with modifications i was able to make it work for custom devices in ST).
after digging to figure out why the python code was working and the ESP SSDP lib was not i noticed there is a string comparison in the grovy file and it was failing to match the udn with the original usn device id. The ST groovy code could be changed to remedy this problem but i wonder if it should be fixed here, because so many other examples of SSDP discovery take care in ensuring the usn and udn match exactly.
___________
Summary, I think the USN and UDN values should match exactly. This will fix issues, allowing for much easier integration with smart hubs that need the device ids to match. Allowing me to use these libraries and not need to roll a custom SSDP handler.
PIO is taking 27+ minutes now, very close to the runtime limit.
Split into even and odd, just like standard Arduino. Each PIO job
takes ~14-15 minutes and can go in parallel.
Content length provides context into the size of the upload, it's not
the exact form body size it's off by the request header info, but it was
already parsed by the library and provides little to no additional
overhead to pass on for use in request handlers.
Currently post args are only available at the end of upload but they are already listed - this PR just expose them with minimal changes
It also set a define for post args array size originaly set to 32
Many objects now expect a WiFiClient* object to be passed to them and
potentially re-used multiple times (HTTPClient, others). Clearing the
authentication options on a ::stop means they can never reconnect.
Remove the option clearing in ::stop

The thunk code needs to be visible to the core routines, so move it to the
cores/esp8266 directory. Probably need to refactor the stack setup and the
bearssl portion to avoid dependency on bearssl libs in cores/esp8266
* Add 2nd stack dump utility routine
* Refactor once more, update stack size, add stress
Make stack_thunks generic, remove bearssl include inside of cores/esp8266.
Allocate the stack on a WiFiServerSecure object creation to avoid
fragmentation since we will need to allocate the stack to do any
connected work, anyway.
A stress test is now included which checks the total BearSSL second
stack usage for a variety of TLS handshake and certificate options
from badssl.org.
* Update to latest to-thunks branch
* Add BearSSL device test using stack stress
Run a series of SSL connection and transmission tests that stress
BearSSL and its stack usage to the device tests.
Modify device tests to include a possible SPIFFS generation and
upload when a make_spiffs.py file is present in a test directory.
* Use bearssl/master branch, not /to-thunks branch
Update to use the merged master branch of bearssl. Should have no code
changes.
Fix link to WiFiEvents
