When we specify GIT_TRACE2_CONFIG_PARAMS or trace2.configparams,
trace2 will prints "interesting" config values to log. Sometimes,
when a config set in multiple scope files, the following output
looks like (the irrelevant fields are omitted here as "..."):
...| def_param | ... | core.multipackindex:false
...| def_param | ... | core.multipackindex:false
...| def_param | ... | core.multipackindex:false
As the log shows, even each config in different scope is dumped, but
we don't know which scope it comes from. Therefore, it's better to
add the scope names as well to make them be more recognizable. For
example, when execute:
$ GIT_TRACE2_PERF=1 \
> GIT_TRACE2_CONFIG_PARAMS=core.multipackIndex \
> git rev-list --test-bitmap HEAD"
The following is the ouput (the irrelevant fields are omitted here
as "..."):
Format normal:
... git.c:461 ... def_param scope:system core.multipackindex=false
... git.c:461 ... def_param scope:global core.multipackindex=false
... git.c:461 ... def_param scope:local core.multipackindex=false
Format perf:
... | def_param | ... | scope:system | core.multipackindex:false
... | def_param | ... | scope:global | core.multipackindex:false
... | def_param | ... | scope:local | core.multipackindex:false
Format event:
{"event":"def_param", ... ,"scope":"system","param":"core.multipackindex","value":"false"}
{"event":"def_param", ... ,"scope":"global","param":"core.multipackindex","value":"false"}
{"event":"def_param", ... ,"scope":"local","param":"core.multipackindex","value":"false"}
