Commit 37f815cad0 ("moveconfig: Use a function to read files") adds a
helper function that can read a file as lines, but strips the newline
characters. This change broke parts of moveconfig code that relied on
their existence, resulting in a few issues:
Configs that are defined as empty aren't removed from header files (e.g.
"#define CONFIG_REMAKE_ELF"). Make regex patterns use '\b' to match word
boundaries instead of '\W' (which matched the newlines) so these lines
still match and get removed.
All changes in defconfig are considered removed by savedefconfig even
if they weren't, and line continuations in the headers aren't recognized
and removed properly, because their checks explicitly look for a newline
character. Remove the character from both comparisons.
The printed diff of header files is wrongly formatted and raises an
IndexError if a blank line was removed. Let print() print the new lines,
and use size-independent ways to check strings to fix the diff output.

|
|
|
|
Some CONFIG options can be implied by others and this can help to reduce
|
|
the size of the defconfig files. For example, CONFIG_X86 implies
|
|
CONFIG_CMD_IRQ, so we can put 'imply CMD_IRQ' under 'config X86' and
|
|
all x86 boards will have that option, avoiding adding CONFIG_CMD_IRQ to
|
|
each of the x86 defconfig files.
|
|
|
|
This function uses the moveconfig database to find such options. It
|
|
displays a list of things that could possibly imply those in the list.
|
|
The algorithm ignores any that start with CONFIG_TARGET since these
|
|
typically refer to only a few defconfigs (often one). It also does not
|
|
display a config with less than 5 defconfigs.
|
|
|
|
The algorithm works using sets. For each target config in config_list:
|
|
- Get the set 'defconfigs' which use that target config
|
|
- For each config (from a list of all configs):
|
|
- Get the set 'imply_defconfig' of defconfigs which use that config
|
|
-
|
|
- If imply_defconfigs contains anything not in defconfigs then
|
|
this config does not imply the target config
|
|
|
|
Params:
|
|
config_list: List of CONFIG options to check (each a string)
|
|
add_imply: Automatically add an 'imply' for each config.
|
|
imply_flags: Flags which control which implying configs are allowed
|
|
(IMPLY_...)
|
|
skip_added: Don't show options which already have an imply added.
|
|
check_kconfig: Check if implied symbols already have an 'imply' or
|
|
'select' for the target config, and show this information if so.
|
|
find_superset: True to look for configs which are a superset of those
|
|
already found. So for example if CONFIG_EXYNOS5 implies an option,
|
|
but CONFIG_EXYNOS covers a larger set of defconfigs and also
|
|
implies that option, this will drop the former in favour of the
|
|
latter. In practice this option has not proved very used.
|
|
|
|
Note the terminoloy:
|
|
config - a CONFIG_XXX options (a string, e.g. 'CONFIG_CMD_EEPROM')
|
|
defconfig - a defconfig file (a string, e.g. 'configs/snow_defconfig')
