Work Description: youngoli commented on pull request #8655: [BEAM-7393]
Misc. improvements to Go error formatting.
URL: https://github.com/apache/beam/pull/8655
This is just three small changes:
1. Remove default top-level error messages. If a top-level msg wasn't set
then just don't display any. Originally top-level messages were always
displayed because it was assumed the error would be confusing if it started
with context instead of an error message. But in practice that's actually less
confusing.
Old behavior:
```
error message
Full Error:
context:
more context:
error message
```
New behavior:
```
context:
more context:
error message
```
2. Align the "Caused by:" msg on wrapped errors with the context
messages, to improve readability.
Old behavior:
```
error number 4
Caused by:
some context:
error number 3
Caused by:
error number 2
Caused by:
error number 1
```
New behavior:
```
error number 4
caused by:
some context:
error number 3
caused by:
error number 2
caused by:
error number 1
```
3. Improvement to an error message that I missed.

> Just need a second pass on error formatting. Two things are bothering me:
> # Default top-level messages are a bit too repetitive and obtuse. Right now
> if there's any kind of context or wrapping the top-level message is just the
> base error and this is usually confusing.
> # When an error is wrapped you have a line for "Caused by:" and it can be
> hard to read. Example:
> {noformat}
> error number 4
> caused by:
> some context:
> error number 3
> caused by:
> error number 2
> caused by:
> error number 1{noformat}
> Gotta make this example easier to read.
