This is redundant on its own, as only a single symbol can be
selected/implied, meaning just .name will work fine too. It means that
all symbols appearing in the __str__() representation of symbols and
choices are now printed via expr_str() though, which might come in handy
soon.
|
|
- Detect Symbol directly instead of as (not tuple) + (not choice)
- Test explicitly for a tuple (non-Symbol) in NOT
- Add some tests to get better coverage for NOT and parentheses
|
|
- Rename to name_and_loc(), to be consistent with the kconfiglib.py
version
- Use a comment instead of a docstring. Shorten the description a bit
too.
- Piggyback a missing # in conf3 in the module docstring. Typo.
|
|
This has no effect.
Model the warning on the one for selecting a symbol with unsatisfied
dependencies.
This is a Kconfiglib-exclusive warning so far.
|
|
|
|
Bit shorter, still clear in context.
|
|
Simplify the looping and remove some comments that aren't super helpful.
Also put " - " at the beginning of the lines listing the selecting
symbols. Bit more readable.
|
|
A valid int/hex user value can never be an empty string, so they test
can be simplified.
|
|
The Kconfig object is replaced immediately after it.
|
|
Example warning:
warning: user value 0x100 on the hex symbol HEX (defined at Kconfig:18) ignored due to being outside the active range ([0x13, 0x73]) -- falling back on defaults
This is a Kconfiglib-exclusive warning. It might be tricky to implement
in the C tools, due to weird two-phase handling of int/hex symbols.
There is unfortunately no easy way to map the warning back to a .config
line, as the active 'range' can't be known in general until the entire
configuration has been read (consider 'range 0 10 if FOO' for example).
Instead, the warning is generated when the symbol value is calculated.
|
|
set_value() already rejects invalid int/hex values, so there's no need
to check the value in str_value().
|
|
|
|
No need to create a list. glob() just does list(iglob()) internally as
well.
|
|
There's no need to handle prompts like defaults, selects, etc. in
_parse_properties(), because prompts belong to menu nodes, which means
only local dependencies will be propagated anyway.
Makes the code a bit less twisty.
|
|
Consistent with how dependencies are propagated elsewhere.
Get rid of the 'parent_dep' variable too.
|
|
|
|
|
|
Bit more readable to have the parent node and the previous node next to
each other.
Also rename 'prev_node' to just 'prev', to be consistent with 'parent'.
There's fewer parameters than in the past now, making it pretty easy to
follow anyway. Remove some inline parameter-related comments too.
|
|
- Restructure the test.
- Call the function _int_hex_ok() instead. Bit less spammy. Also add a
doc-comment to explain it.
|
|
'left' is guaranteed to be 'sym' if the preceding conditional was true.
|
|
Also rename it to _auto_menu_dep().
|
|
Originally taken from the C implementation, but seems pointless. The
only way to get an empty prompt text is to explicitly define a symbol
with e.g. 'prompt ""'.
|
|
Works like menuconfig.py, but just dumps the tree, with a specified
.config file as base. Handy for diffing.
|
|
Only adds daac69d ("Add a globbing source statement").
'gource' doubles as an include-if-exists function.
|
|
Removed in linux-next.
|
|
A menuconfig implementation built on top of Kconfiglib using TkInter.
|
|
Just for completeness.
|
|
|
|
'gsource' works like 'source', but takes a glob pattern and sources all
matching files. Works as a no-op if no files match, and hence doubles as
an include-if-exists function, similar to '-include' in 'make'.
Add a 'grsource' statement as well, mirroring 'rsource'.
Came up in https://github.com/ulfalizer/Kconfiglib/pull/40.

Includes a small API behavior change, hence the major version bump:
- db63301 ("Return "" for unwritten symbols in Symbol.config_string")
New features:
- Support for incremental builds using the same scheme as the
include/config/ directory in the C tools. See the new
Kconfig.sync_deps() function and commit 378dedc ("Add support for
incremental builds").
- Minimal configuration (defconfig) writing, generating identical files
to the C implementation. See commit 652f11b ("Add minimal
configuration file generation support").
The C 'make savedefconfig' implementation is currently broken in
obscure cases involving tristate choices (due to broken invalidation
code), so the tests are disabled for now. I have a patch for the C
implementation that I will submit.
Fixes:
- user_value wasn't set for choice symbols set to y via load_config()
with replace=True. Fixed by commit 0bd841d ("Properly remember y user
values for choice symbols"). Didn't affect correctness, only the API.
Other changes:
- 778ec47 ("Only write '# CONFIG_FOO is not set' for visible symbols")
mirrors a change I made to the C tools.
- bbe3ae9 ("Do not write the defconfig_list symbol to .config") mirrors
another change made to the C tools.
- Misc. refactoring and cleanup.
|

Works like 'make savedefconfig' in the C tools. Call it
write_min_config() rather than write_defconfig() to be a bit more
explicit.
Add a test similar to test_defconfig that compares Kconfiglib minimal
configuration output against the C implementation, for all defconfig
files.
Disable the tests for now. The C tools have a bug that causes an
incorrect configuration to be generated for tristate choices in some
cases. They will be re-enabled once those are fixed.
|

Commit e8b4ecb ("Don't special-case user_value for choice symbols set to
y") was meant to make user_value reflect an y value assigned to a choice
symbol, but didn't get it right for load_config() with replace=True: The
user value was set at first, but was then unset again due to a misplaced
'_was_set = True' assignment.
This commit makes y choice symbol user values always be remembered. The
correctness of generated files was not affected, since the user
selection of a choice is actually remembered as Choice.user_selection.
The previous commit just turned into a no-op for load_config() with
replace=True.

defconfig_files() yields all the defconfig files for a particular arch/
subdirectory. This will allow reuse when savedefconfig is tested.
Also simplify the code a bit.
|
|
Not that important of a stat, plus there might be more tests that
process defconfig files soon, making it kinda meaningless.
|
|
No great need to log timestamps anymore.
|
|
The 'for' overrode 'srcarch', which is currently harmless, but ugly.
|
|
Makes sense as SRCARCH holds the arch/ subdirectory and _arch might be
confused for ARCH.
|
|
Get rid of the compare_configs flag and just do the comparison from the
test functions themselves with a helper.
Also get rid of the test_load() test. That's indirectly tested through
the other tests, and test_alldefconfig() runs first and is speedy.
|
|
The original idea was that it might be handy to look up docstrings for
internal functions from the Python prompt (or an IDE) while figuring out
the code.
Not sure it's that useful in practice though. Comments shorten the code
a bit, and might make it clearer at a glance that the function is
internal.
|
|
Makes it harder to miss.
|
|
The _get_* prefixes don't improve readability and are inconsistent: All
other getters are simply named after the thing they fetch.
Leftover from Kconfiglib 1.

Mirrors the following change to the C tools, now in linux-next:
commit c21a6e352766005d42c1ccae32b31e0438903eb9
Author: Masahiro Yamada <yamada.masahiro@socionext.com>
Date: Sat Feb 17 03:38:32 2018 +0900
kconfig: set SYMBOL_AUTO to the symbol marked with defconfig_list
The 'defconfig_list' is a weird attribute. If the '.config' is
missing, conf_read_simple() iterates over all visible defaults,
then it uses the first one for which fopen() succeeds.
config DEFCONFIG_LIST
string
depends on !UML
option defconfig_list
default "/lib/modules/$UNAME_RELEASE/.config"
default "/etc/kernel-config"
default "/boot/config-$UNAME_RELEASE"
default "$ARCH_DEFCONFIG"
default "arch/$ARCH/defconfig"
However, like other symbols, the first visible default is always
written out to the .config file. This might be different from what
has been actually used.
For example, on my machine, the third one "/boot/config-$UNAME_RELEASE"
is opened, like follows:
$ rm .config
$ make oldconfig 2>/dev/null
scripts/kconfig/conf --oldconfig Kconfig
#
# using defaults found in /boot/config-4.4.0-112-generic
#
*
* Restart config...
*
*
* IRQ subsystem
*
Expose irq internals in debugfs (GENERIC_IRQ_DEBUGFS) [N/y/?] (NEW)
However, the resulted .config file contains the first one since it is
visible:
$ grep CONFIG_DEFCONFIG_LIST .config
CONFIG_DEFCONFIG_LIST="/lib/modules/$UNAME_RELEASE/.config"
In order to stop confusing people, prevent this CONFIG option from
being written to the .config file.

Use the result from the initial str_value call in more places.
Also add a comment to make it clear how _write_to_conf is calculated,
mirroring the ones in write_config() and write_autoconf().
|
|
|
|
Instead of creating an empty initial auto.conf and immediately loading
it, look for a missing auto.conf in _load_old_vals() and treat that the
same as an empty auto.conf (by returning after clearing the old values).
The initial auto.conf will then be written as normal by
_write_old_vals().
Also flesh out the sync_deps() docstring a bit:
- Make it clear that sync_deps() should be run at each build
- Be more explicit about what it means for a symbol to have changed
(different output in autoconf.h)
|
|
An initial empty auto.conf will be created, just as when sync_deps()
creates the directory.
This is more flexible. There's no good reason to require the directory
to be created by sync_deps().
|
|
"malformed expression" should be clear enough for a missing end
parenthesis too. Expressions are generally short.
