This script calls through to Kconfiglib.sync_deps() and can be used to
implement incremental builds.
Having additional dependency mechanisms for changes to Kconfig files and
environment variables is redundant, because those changes indirectly
influence symbol values and will be caught as well.
|
|
cached_search_strings was renamed to cached_search_nodes.
|
|
The defconfig tests tend to find any issue quickly, so keep those first.
Go alldefconfig -> allnoconfig -> allmodconfig -> allyesconfig after
that, and do the sanity checks at the end.
|
|
Setting all tristate choice symbols to 'm' is enough to always do the
right thing in practice. It has no effect for bool choice symbols (since
'm' will be ignored), but forces symbols in m-mode choices to 'm'.
'm' will also be ignored for tristate choice symbols in choices in 'y'
mode, because tristate is automagically converted to bool there.
|
|
Verified to produce identical output to 'make allmodconfig', for all
arches.
Will be packaged.
|
|
To-be-packaged scripts now live in the root.
|
|
Will be packaged.
Piggyback test suite cleanups to make test names match the name of the
script being tested.
|
|
No longer used after the tool helpers were added.
|
|
Removes repeated KCONFIG_CONFIG boilerplate.
Also make allyesconfig use KCONFIG_CONFIG when writing (oversight), and
document the sys.exit() behavior for standard_kconfig().
|
|
standard_kconfig() gets the top-level Kconfig file from the first
command-line argument, defaulting to "Kconfig". This removes some
boilerplate from tools.
|
|
Move to the root, simplify a bit, provide an entry point function (for
setuptools's entry_points).
|
|
Could do something similar to allnoconfig.py for the packaged version.
|
|
Handy e.g. when implementing advanced search features.
|
|
Useful in various places outside the library, e.g. in the upcoming
packaged allyesconfig implementation, and when generating documentation.
|
|
Oops.
|
|
Put to-be-packaged stuff in the root.
Use allnoconfig_simpler.py, and rename allnoconfig.py to
allnoconfig_walk.py and keep it as an example.
|
|
All the packaged code will appear in the root.
|
|
setuptools' 'entry_points' gives nice behavior on Windows. It requires
that the module has an entry point function. Create one and move the
command line argument handling to it.
Piggyback KCONFIG_CONFIG support, and make the script executable
(oversight).
|
|
An output file should still be generated if you're happy with the
default settings.
|
|
This matches the C tools. Hadn't noticed they had the same feature.
|
|
Had missed sys.exit(msg).

Commit cbf32e2 ("Expand environment variables in strings directly")
added direct expansion of environment variables is strings, with commit
b9384a1 ("Restore compatibility with $UNAME_RELEASE") adding a hack to
restore compatibility with the predefined $UNAME_RELEASE symbol, used by
DEFCONFIG_LIST in the Linux kernel.
With the compatibility hack in place, there's no longer any need to
define UNAME_RELEASE as a proper symbol. Remove it.

D'oh

Shaves ~6% off the _parse_help() runtime for the x86 Kconfigs in
cProfile.

This takes some heuristics, as it's indistinguishable from a reference
to an undefined symbol. Guess that the quotes are missing if the
'default' value isn't all-uppercase.
|
|
|
|
It's easy to miss at the top, especially as it's centered. Have a
generic 'Symbol information', 'Choice information', etc., title instead.
|
|
The name is always shown for items without prompts (which are always
promptless symbols). Only show-name mode needs the symbol/choice check.
|
|
Pressing 'c' toggles show-name mode, where names of symbols are
displayed before their prompt.
|
|
|
|
Only show "real" (non-indented) menus, like in the menu path at the top.
|
|
This is consistent with how they're shown in the info dialog. Looks less
confusing for empty strings too.
|
|
Makes it double as a quick way to check if something is enabled.
Suggested by Randy Dunlap.

This gets rid of some slight input jerkiness while inputting e.g.
'.*debug' on my machine (though the '.*' is redundant there), due to
faster matching. The '.*' probably has bad interactions with
re.search(), which matches anywhere in the string.
A plain "debug" matches about 70% faster, though it's fast enough to
feel instant anyway.
|
|
|
|
|
|
Instead of doing a single search of the '<symbol name> "<prompt>"'
string. This avoids gotchas like '_DEBUG$' not matching FOO_DEBUG if
FOO_DEBUG has a prompt.
|
|
|
|
re.error.msg was added in Python 3.5. Show a generic error message when
it isn't available.
|
|
This makes it clearer when an edit box is scrolled, especially when
backspacing. The cursor will now only go to the far left/right of the
edit box at the start/end of the string.
Reuse _SCROLL_OFFSET to specify the scroll offset.
|
|
List the working directory, which might not be obvious, and support
referring to the home directory with ~.
Support for multiple lines of help text in input dialogs was added as
well.
|

Since commit cbf32e2 ("Expand environment variables in strings
directly"), Kconfiglib expands environment variables directly in strings
instead of using the 'option env=...' mechanism (this is planned for the
C tools too). This new behavior is backwards-compatible as long as all
'option env=...' symbols have the same name as the environment variables
they reference.
Warn if 'option env="FOO"' appears on a symbol that isn't named FOO, to
point out compatibility issues and help with debugging.
|
|
This code is surprisingly hot.
|
|
The Kconfig definition already lists the location and menu path, and now
shows up at the top.
|
|
Only a single caller left now, in a hot loop.
|
|
Also strip the prompt in that case. Leading/trailing whitespace in
prompts leads to ugly workarounds in e.g. reStructuredText
documentation, where '*prompt *' is invalid.
|
|
UNAME_RELEASE is expanded in one of the 'default's of the DEFCONFIG_LIST
symbol in the Linux kernel. This broke after "$FOO" was changed to
directly expand to the value of the environment variable FOO, rather
than to the value of the symbol FOO.
Restore compatibility with a small wrapper.
|
|
Automatically turn on show-all mode if the currently selected node
becomes invisible after loading the new configuration.
Show an are-you-sure dialog if there are unsaved changes.
A wart here is that there currently isn't a way to get 'errno' and
'strerror' from the IOError exception returned by load_config(). Hack
around it by opening the configuration file separately with open()
first, just to catch any obvious errors.
