COMPONENT_DIRS and EXTRA_COMPONENT_DIRS should be defined as CMake
lists, using 'set' or 'list' commands. Some applications written
for earlier versions of ESP-IDF used to define these variables as
space separated strings.
For example, the following is correct:
set(EXTRA_COMPONENT_DIRS path/to/components path/to/more/components)
The following is not correct:
set(EXTRA_COMPONENT_DIRS "${EXTRA_COMPONENT_DIRS} component1")
set(EXTRA_COMPONENT_DIRS "${EXTRA_COMPONENT_DIRS} component2")
The string "component1 component2" may indicate a single directory
name with a space, or two directory names separated by space.
However due to the fact that such way of defining EXTRA_COMPONENT_DIRS
was supported in IDF 4.3 and earlier, we need to provide backward
compatibility for it.
This commit introduces a new script, split_paths_by_spaces.py, which
is invoked if EXTRA_COMPONENT_DIRS or COMPONENT_DIRS variable contains
spaces. The script tries to determine if each space should be
interpreted as a separator or as part of the directory name.
When this cannot be done unambiguously, the script reports an error.
In all cases when space separators are detected, the script reports
a warning, and prints instructions for fixing the CMakeLists.txt.
Breaking change in this commit: specifying non-existent directories
in COMPONENT_DIRS or EXTRA_COMPONENT_DIRS is no longer allowed.
Fixes WORKING_DIRECTORY argument being passed with spaces escaped `\ `
which causes failure in run_cmd.cmake, since the WORKING_DIRECTORY is
interpreted as having a literal backslash character in it.
New —-list-separator argument of confgen.py and
prepare_kconfig_files.py is used to select which character is used
as list separator. For compatibility with esp-docs, we still keep
support for space separator. Otherwise esp-docs would have to choose
the separator depending on the IDF version.
* Adds implementations of __{atomic,sync}_nand_fetch_n. These builtins
were implemented for other operations but were not defined for NAND.
* Adds implementation of __atomic_OP_fetch_n for all OPs.
* Adds implementation of __sync_OP_and_fetch_n for all OPs.

It can be used in component CMakeLists.txt files when adding "weak"
dependencies between component. A "weak" dependency from A to B is
similar to target_link_libraries(A PRIVATE B), but it gets added only
if B is included in the build.
Use it instead of specifying B as part of PRIV_REQUIRES when the
component can be built (even if with reduced functionality) without
component B being available.
These optional feature produces a graphviz file showing component
dependencies. It is useful for debugging reasons why certain
components got added to the build.
When the build runner has a local git mirror configured via
LOCAL_GIT_MIRROR variable, use that mirror when cloning IDF insider
the docker build job. Follows similar logic for
LOCAL_GITLAB_HTTPS_HOST, which is used for geo nodes.

* Migrate test cases from IDF test runner to Unity fixture.
* Tighten heap checks in the test case a bit.
* Run formatting script on test_wl.c
* NEW: Define 4 test configurations, including configs with 512 byte
sector size. Previously these configs weren't tested in CI.
* NEW: The test app only runs for ESP32 and ESP32-C3 (one chip for
each architecture). The component is pretty high level so we don't
need to test it for each chip. This reduces the load on CI.
In 4972605, high-level interrupt handler hook was renamed from
ld_include_highint_hdl to ld_include_panic_highint_hdl. However the
change wasn't applied in GNU Make based build system. As a result,
the default interrupt handler was linked and features which depended
on the high-level interrupt didn't work.

Add new Kconfig option to enable -msave-restore flag for RISC-V
targets. This option can be used to reduce binary size by replacing
inlined register save/restore sequences with library calls.
spi_flash_generic_timeout is currently defined in the header file,
which makes it a common symbol between translation units where this
header file is included. It is also defined in
spi_flash_chip_generic.c.
Add an explicit `extern` to prevent multiple definition errors.
Clang warns that the original code wouldn't have any effect:
warning: indirection of non-volatile null pointer will be deleted,
not trap [-Wnull-dereference]
note: consider using __builtin_trap() or qualifying pointer
with 'volatile'
__builtin_trap translates to 'break 1, 15' instruction on Xtensa,
which might be okay in this case. However to absolutely certainly not
break anything for GCC builds, add 'volatile' instead.
Toolchain CMake files for clang currently pass -ffreestanding option
to prevent clang from picking the wrong copy of stdint.h. This is a
temporary hack until we fix clang distributions to not include the
GCC version of stdint.h. This hack, however, results in setting
__STDC_HOSTED__=0, which is being checked by cbor header files,
making some required functions unavailable as a result.
Undefine __STDC_HOSTED__ as a workaround. This flag is only passed
when compiling cbor itself.
We will likely need to check clang version as well, eventually.
However at the moment clang builds change too often for such check
to be maintainable. Disable it for clang.
This feature was added when we thought that target components might be
added out of IDF tree. That never became possible, and with recent
changes in IDF architecture it is unlikely that this feature will be
necessary any time soon. Remove it, simplifying the code.
This is an experimental feature intended at the moment for ESP-IDF
developers only.
If IDF_TOOLCHAIN=clang environment variable or CMake variable is set,
use toolchain-clang-esp32xx.cmake instead of toolchain-esp32xx.cmake.
These changes aren't sufficient to actually build any IDF project with
clang; subsequent commits add a few workarounds required to do this.
Toolchain files are added for esp32 and esp32s2, which are the targets
supported in our llvm-project fork at the moment.
Since these functions receive the pointer to reent structure, they
should set errno in it rather than using thread-local errno.
This didn't cause practical issues because console functions in IDF
are only called from threads, and in that case 'r' is a pointer to
the thread-local structure, so &errno is the same thing as
&__errno_r(r). Still, fixing this for consistency.
When CONFIG_VFS_SUPPORT_IO is disabled, _read_r and _write_r
implementations in syscalls.c are used to provide console I/O via
esp_rom_uart_tx_one_char/esp_rom_uart_rx_one_char.
When newlib opens a (FILE*) stream, it calls fstat to check if the
underlying file is character-oriented. In this case, it configures the
stream to use line buffering. Otherwise (or if fstat fails) the stream
is opened as block buffered.
Since fstat wasn't provided, stdin/stdout/stderr streams got opened in
block buffered mode. For console, we need line buffered output so that
the stream buffer is flushed each time a complete line (ending with
'\n') is sent to stdout or stderr.
Fix by implementing _fstat_r stub, setting st->st_mdoe=S_IFCHR.
