So far, it is difficult that the state of perf configs is looked through
and there's no knowing what kind of other variables except variables in
perfconfig.example.
Also perf configs can't be changed without manually modifying $HOME/.perfconfig
or
$(sysconfdir)/perfconfig file. So I suggest this patchset of the perf-config
command
which can list, get, set, remove perf configs or list with default config
values as below.
Changes in v10:
- Split perf-config.txt into several patches for each section and
replace some
paragraphes with better proper things as suggested by Arnaldo and
Namhyung
(PATCH v10 2~15/22)
- Correct wrong default values for each variable as suggested by
Namhyung
(PATCH v10 18/22)
- Remove the compare name function.
Changes in v9:
- Add the compare name functionality treating '-' and '-' as being the
same thing
for usability (PATCH v9 4/9)
Changes in v8:
- Correct small typing errors in a perf-config documention (PATCH v8
1/8)
- Split the collecting configs part into a separate patch (PATCH v8 3/8)
- Use new enum and struct for default configs instead of hard-coded
value
as suggested by Namhyung (PATCH v8 4/8)
Changes in v7:
- Modify explanations of syntax and options(color, gtk, tui, buildid,
annotate)
to be better proper descriptions as suggested by Arnaldo (PATCH v7 1/7)
Changes in v6:
- Split a 'set' feature patch into two patch to separate
normalize_value() from it.
(PATCH v6 5/7, PATCH v6 6/7)
- Bug fix : 'remove' and 'set' malfunctions when without a specific
file-option.
(If file-option isn't used, 'remove' feature had to use both user and
system
config file and 'set' feature had to only handle user config file.)
(PATCH v6 5/7, PATCH v6 7/7)
Changes in v5:
- Simplify the switch statement in cmd_config()
- Set a config file path with '--system' or '--user'
instead of '--global' or '--system' as suggested by Namhyung. (PATCH v5
2/6)
- The patch about 'get' and 'set 'split into two patchs
as suggested by Namhyung. (PATCH v5 4/6, PATCH v5 5/6)
Changes in v4:
- If some config value is default value, notice it is '(default)'
as suggested by Jirka. (PATCH v4 3/5)
- If there wasn't any perfconfig file, perf-config malfunctioned like
Jirka pointed out. So add exception routine with '--global' and
'--system'
option which can select perf config file path. (PATCH v4 2/5)
Changes in v3:
- Add a config variable 'kmem.default' with a default value as
suggested by Namhyung.
(PATCH v3 2/5, PATCH v4 3/5)
Changes in v2:
- Change option name of listing all configs as '--list-all' instead of
'--all'
as suggested by Namhyung. (PATCH v2 3/4, PATCH v4 4/5)
- Correct small infelicities or typing errors in a perf-config
documention
as suggested by Arnaldo. (PATCH v2 1/4, PATCH v4 1/5)
- Declaration a global variable 'static struct default_configsets' has
config variables
with default values instead of using a 'util/PERFCONFIG-DEFAULT' file.
(PATCH v2 3/4, PATCH v4 3/5)
- Add a function to normalize a value and check data type of it.
(PATCH v2 2/4, PATCH v4 3/5)
- Simplify parsing arguments as arguments is just divided by '=' and
then
in front of '.' is a section, between '.' and '=' is a name, and behind
'=' is a value.
(PATCH v2 2/4, PATCH v4 3/5)
- If run perf-config command without any option, perf-config work as
'--list'.
(PATCH v2 1/4, PATCH v4 1/5)
