Remove get.py percent dump to shorten PIO output 99%.
Use latest release version of PIO, not bleeding edge, to fix
failures introduced in devel (non-release) PIO versions.
Thanks, @mcspr, for noticing this!
* Upgrade to GCC 9.1 toolchain
* Rebuilt using pure GNU binutils and GCC
Remove dependencies on earlier forked GNU utilities (gcc-xtensa,
binutils-gdb-xtensa) and just use GCC sources, unmodified (except for
patches in the esp-quick-toolchain directories).
* Rebuild bearssl using new toolchain
* Fix GDBstub linkage options
GDB works with pure GNU GCC and pure GNU binutils now. Still warnings
galore, but tested with the example sketch in the docs.
* Fix digitalRead alias warning
* Remove gdb stub warnings w/a pragma
* Fix deprecated implicit copy ctors in IP code
Fix some warnings present in GCC8/9 in the IPAddress code
In AddressListIterator there was a copy constructor which simply copied
the structure bit-for-bit. That's the default operation, so remove it
to avoid the warning there.
IPAddress, add a default copy constructor since the other copy
constructors are simply parsing from one format into a native ip_addr_t.
@d-a-v, can you give these a look over and see if they're good (since
IP stuff is really your domain).
* Fix AxTLS alias function defs to match real code
* Fix WiFiClientSecure implicit default copy ctor
These both use shared-ptrs to handle refcnts to allocated data, so using
the default copy constructor is fine (and has been in use for a long
time).
* Dummy size for heap to avoid GCC 8/9 warnings
Make GCC think _heap_start is large enough to avoid the basic (and
incorrect) bounds-checking warnings it produces. The size chosen is
arbitrary and does not affect the actual size of the heap in any way.
* Make heap an undefined extend array
Instead of a bogus size, use an indefinite size for the heap to avoid
GCC warnings
* Trivial tab to space fix
* Update SDFat to remove FatFile warnings
* Fix ticker function cast warnings in GCC 9
The callback function is defined to take a (void*) as parameter, but our
templates let users use anything that fits inside sizeof(void*) to be
passed in. Add pragmas to stop GCC warnings about this, since we
already check the size of the type will fit in the allocated space.
* Remove GCC support fcn that's in ROM
Manually delete the divdi3.so from the libgcc.a library by running the
updated EQT's 9.1-post script.
* Make exceptions work again, get std::regex up
Exceptions are broken on all builds (GCC4.8-9.1) due to the removal of
the PROGMEM non-32b read exception handler (added in the unstable
pre3.0.0).
Build the exception code with -mforce-l32 and patch
accordingly to avoid LoadStore errors.
Apply patches to select portions of the regex lib which use _stype_
(which is now in flash).
* Rebuild Bearssl using latest GCC push
* Automate building of BearSSL and LWIP w/new toolchain
* Workaround g++ template section problem for exception strings
G++ seems to throw out the section attributes for templates. This means
that the __EXCSTR(a synonym for "PSTR()") is ignored and exception.what
strings are stored in RODATA, eating up RAM.
Workaround by using the linker to place the strings keying off their name
("*__exception_what__*").
* Rebuild moving exception.what to unique names
Exception.whats are now all in __exception_what__ and can be moved by
the linker to flash. Works aroung G++ issue with segments being lost in
templates.
* Rebuild with new LWIP locking
* Update to latest libs, save iram
Move two GCC FP support routines out of iram since they are in ROM
already, saving some add'l IRAM. Same list as gcc 4.8.
* Update BearSSL to latest release
* Fix umm_perf reference to ROM function
* Fix "reinterpret_case is not a constexpr" error
In GCC 9 (and 8 from what I read on SO), a cast of a const int to a
function pointer (via explicit or implicit reinterpret_cast) is not a
constexpr.
````
/home/earle/Arduino/hardware/esp8266com/esp8266/cores/esp8266/umm_malloc/umm_performance.cpp:45:36: error: a reinterpret_cast is not a constant expression

| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
````
Remove the constexpr, potentially increasing heap usage by 4 bytes in
debug mode.
* Update libc.a to latest rev
* Full rebuild of toolchain and libs
* Upgrade to GCC 9.2, released in August 2019
Add builds for all 5 cross-compiles to pass CI
* Move to --std=gnu++14 (C++14 + GNU extensions)
* Fix Ticker merge conflict
* Fix json merge conflict
* One more merge diff fix
* Reapply Ticker.h casting warning fixes for gcc9
* Update with fixes from Sming repo for PSTR and ASM
* Upgrade to -gnu4 toolchain
* Move to gnu5 build with add'l softFP from ROM
* Move add'l softFP from IRAM to flash
Per @mikee47, we miss sone add'l soft-FP routined in the linker which
makes them end up in IRAM. Move them explicitly into flash, like a
couple others we have already done this for.
* Move to std=c++17/c17 in platform, remove abs/round
Move to C++17 and C17 standards on the compiler options.
Remove "register" from core since it is deprecated.
Remove the #define abs() and #define round() which a) overwrote the
C stdlib definitions, poorly, and b) broke the GCC core code which used
"abs" as an internal function name.
Now abs() returns an integer, and not whatever was being absoluted.
fabs() etc. can be used if users need fload/double suport.
round() returns a double now, which is basically what it was returning
in the original case since adding/subtracting by a FP.
* Use std::abs/round to replace the macro definitions
Per discussion w/@devyte, preserve the abs() and round() functionality
via the using statement.
* Remove using std::abs which conflicted with C lib headers
* Add 2nd arg (exception handler) to ets_isr_t
Disassembly of the ROM shows there are 2 params to the ets_isr_t
callback. The first is the arg passed in, the second is a pointer to an
exception frame where you can get info about when the IRQ happened.
* Move the gdbstub example to a subdir
The Arduino IDE and the build CI don't build it without a subdir, so
make one for gdbstub's example so it's visible and tested.
* Fix ets_irq_arratch redefinition and core IRQ handlers
Remove a duplicated, different declaration for ets_irq_attach from
ets_sys.h. It never really even matched the other declaration in the
same header.
Update the core to IRQ handlers to fix the prototype and include the
2nd, unused frame parameter.
* Actually rebuild the libc.a using GCC 9.2
* Fix SPISlave interrupt attach's 2nd parameter
* Rebuild eboot.elf with GCC 9
* Update to latest SoftwareSerial for Delegate fix
* Upgrade to GCC 9.3
* Rebuild all arch toolchains
* Move to GCC 10.1
* Merge master and fix eboot build
GCC10 now uses `-fno-common` so the eboot global variables were being
placed in IRAM. Adjust the makefile and rebuild to fix.
* Built complete toolchain for all archs
* Pull in latest PSTR changes and fix GCC10.1 build
Somehow the prior GCC build's -mforce32 patch wasn't applying correctly,
but I was still able to get a binary. Fixed. Also pulled in latest
PSTR changes in progmem.h
* Update platform.io to platform C/C++ standards
* Use PR's toolchain in platformio build
* Fix several asm warnings in PIO build
* Optional stack smash protection -fstack-protector
Add a menu to enable GCC's built-in stack smash protection. When a
subroutine goes past its end of stack, generate a crashdump on function
exit like:
````
GCC detected stack overrun
Stack corrupted, stack smash detected.
>>>stack>>>
ctx: cont
sp: 3fffff20 end: 3fffffc0 offset: 0000
3fffff20: 40202955 00000001 0000001c 4020287e
3fffff30: feefeffe 000000fd 00000000 00000000
...
<<<stack<<<
````
Disabled by default because there is a small per-function code overhead
(and CPU time if the function is called very frequently and is very
small).
BearSSL and LWIP are not built using stack smash detection, yet.
* Fix duplicated stc=gnu99/c17 in build
* Dump faulting function PC in stack overflow
Report a fake exception to have the exception decoder print the actual
faulting function. This won't tell you where in the function the issue
happened, but it will tell you the function name first and foremost.
* Rebuild with Platform.io JSON tag in release tgzs
* Updated Example to use ArduinoJson6
* Updated save method to Serialize and not Deserialize
* Updated References to ArduinoJson 6.11.0
* Style Fix
* another line missed
* Added the file extension to the new version
* Add a FAT filesystem for SD cards to Arduino FS
Arduino forked a copy of SD lib several years ago, put their own wrapper
around it, and it's been languishing in our ESP8266 libraries ever since
as SD. It doesn't support long file names, has class names which
conflict with the ESP8266 internal names, and hasn't been updated in
ages.
The original author of the SD library has continued work in the
meantime, and produced a very feature rich implementation of SdFat. It
unfortunately also conflicts with the class names we use in ESP8266
Arduino and has a different API than the internal SPIFFS or proposed
LittleFS filesystem objects.
This PR puts a wrapper around the latest and greatest SdFat library,
by forking it and wrapping its classes in a private namespace "sdfat,"
and making as thin a wrapper as possible around it to conform to
the ESP8266 FS, File, and Dir classes.
This PR also removes the Arduino SD.h class library and rewrites it
using the new SDFS filesystem to make everything in the ESP8266
Arduino core compatible with each other.
By doing so it lets us use a single interface for anything needing a
file instead of multiple ones (see SDWebServer and how a different
object is needed vs. one serving from SPIFFS even though the logic is
all the same). Same for BearSSL's CertStores and probably a few others
I've missed, cleaning up our code base significantly.
Like LittleFS, silently create directories when a file is created with
a subdirectory specifier ("/path/to/file.txt") if they do not yet exist.
Adds a blacklist of sketches to skip in the CI process (because SdFat
has many examples which do not build properly on the ESP8266).
Now that LittleFS and SDFS have directory support, the FS needs to be
able to communicate whether a name is one or the other. Add a simple
bool FS::isDirectory() and bool FS::isFile() method. SPIFFS doesn't
have directories, so if it's valid it's a file and reported as such.
Add ::mkdir/::rmdir to the FS class to allow users to make and destroy
subdirectories. SPIFFS directory operations will, of course, fail
and return false.
Emulate a 16MB SD card and allow test runner to exercise it by using
a custom SdFat HOST_MOCK-enabled object.
Throw out the original Arduino SD.h class and rewrite from scratch using
only the ESP8266 native SDFS calls. This makes "SD" based applications
compatible with normal ESP8266 "File" and "FS" and "SPIFFS" operations.
The only major visible change for users is that long filenames now are
fully supported and work without any code changes. If there are static
arrays of 11 bytes for old 8.3 names in code, they will need to be
adjusted.
While it is recommended to use the more powerful SDFS class to access SD
cards, this SD.h wrapper allows for use of existing Arduino libraries
which are built to only with with that SD class.
Additional helper functions added to ESP8266 native Filesystem:: classes
to help support this portability.
The rewrite is good enough to run the original SDWebServer and SD
example code without any changes.
* Add a FSConfig and SDFSConfig param to FS.begin()
Allows for configuration values to be passed into a filesystem via the
begin method. By default, a FS will receive a nullptr and should so
whatever is appropriate.
The base FSConfig class has one parameter, _autoFormat, set by the
default constructor to true.
For SPIFFS, you can now disable auto formatting on mount failure by
passing in a FSConfig(false) object.
For SDFS a SDFSConfig parameter can be passed into config specifying the
chip select and SPI configuration. If nothing is passed in, the begin
will fail since there are no safe default values here.
* Add FS::setConfig to set FS-specific options
Add a new call, FS::setConfig(const {SDFS,SPIFFS}Config *cfg), which
takes a FS-specific configuration object and copies any special settings
on a per-FS basis. The call is only valid on unmounted filesystems, and
checks the type of object passed in matches the FS being configured.
Updates the docs and tests to utilize this new configuration method.
* Add ::truncate to File interface
Fixes#3846
* Use polledTimeout for formatting yields, cleanup
Use the new polledTimeout class to ensure a yield every 5ms while
formatting.
Add in default case handling and some debug messages when invalid inputs
specified.
* Make setConfig take const& ref, cleaner code
setConfig now can take a parameter defined directly in the call by using
a const &ref to it, leading to one less line of code to write and
cleaner reading of the code.
Also clean up SDFS implementation pointer definition.
