Cannot instrument two functions on the same tracing channel name #19
Description
While writing tests I wanted to instrument multiple functions while using the same tracing channel, so I wrote this:
use crate::common::*;
use orchestrion_js::*;
#[test]
fn param_mutation() {
transpile_and_test(
file!(),
false,
Config::new(
vec![
InstrumentationConfig::new(
"param_mutation",
test_module_matcher(),
FunctionQuery::function_declaration("fetch_simple_args", FunctionKind::Sync),
),
InstrumentationConfig::new(
"param_mutation",
test_module_matcher(),
FunctionQuery::function_declaration("fetch_complex_args", FunctionKind::Sync),
),
],
None,
),
);
}but this will end up rewriting the file with this:
const { tracingChannel: tr_ch_apm_tracingChannel } = require("diagnostics_channel");
const tr_ch_apm$param_mutation = tr_ch_apm_tracingChannel("orchestrion:undici:param_mutation");
const tr_ch_apm$param_mutation = tr_ch_apm_tracingChannel("orchestrion:undici:param_mutation");thus creating the variable tr_ch_apm$param_mutation twice, which is not legal syntax.
We have real use cases for using the same channel for multiple functions. Maybe I just don't know how to do it with the current API, but if it's not possible currently, it would be a welcomed addition.
For now we can work around it by having channel1 and channel2 but it's not optimal.
