One thing that I'd really like input on is this: I'm torn on this. CC @prashantv |

There was a problem hiding this comment.
should we add some testdata of real stack traces from go 1.20 / 1.21 and ensure they parse correctly too?
|
Update:
|
Adds support to the stack parser for reading the full list of functions for a stack trace. This includes the function that created the stack trace; it's the bottom of the stack. We don't maintain the order of the functions since that's not something we need at this time. The functions are all placed in a set.
In Go 1.20, the "created by" lines do not include the "in goroutine" portion.
`Full()` was accidentally dropping the file names from the full traces.
The function tha created a goroutine should not be considered part of its stack. However, we can use that entry to mark the end of a stack trace.

To verify the stacktrace parsing logic, generate real stack traces under the following conditions: - Go 1.21 - Go 1.20 installed with gimme - Go 1.21 with tracebackancestors=10 set The test verifies that the parsed stack traces do not include functions that we did not expect to see in a goroutine's trace.

We should set up a codecov configuration that we actually follow. This is just ignored right now.

Instead of matching for built-in functions with strings.Contains,
use the parsed stack information to match function names exactly.
Following this change, the only remaining strings.Contains are
to match on the goroutine state:
```
% rg strings.Contains
utils_test.go
84: if strings.Contains(s.State(), "run") {
internal/stack/stacks_test.go
249: if strings.Contains(s.State(), "run") {
```
Resolves #41
Depends on #111

Adds support to the stack parser for reading the full list of functions
for a stack trace.
NOTE:
This includes the function that created the stack trace;
it's the bottom of the stack.
We don't maintain the order of the functions
since that's not something we need at this time.
The functions are all placed in a set.
This unblocks #41 (PR incoming)
and allows implementing an IgnoreAnyFunction option
(similar to #80 that has since stalled).
Depends on #110
