* fix(webconnectivity): expose network events
By not exposing network events in webconnectivity, we are missing
several interesting, explanatory data points.
This diff fixes the issue by:
1. enriching the definition of network events to include extra
data useful for performing (manual) data analysis;
2. adding a tags field to network events such that we can add
tags to specific events and understand where they come from;
3. exposing all the (tagged) network events that happen when running
a webconnectivity experiment.
See https://github.com/ooni/probe-engine/issues/1157.
* progress
* more work towards landing this diff
* Apply suggestions from code review
* fix(webconnectivity): allow measuring https://1.1.1.1
There were two issues preventing us from doing so:
1. in netx, the address resolver was too later in the resolver
chain. Therefore, its result wasn't added to the events.
2. when building the DNSCache (in httpget.go), we didn't consider
the case where the input is an address. We need to treat this
case specially to make sure there is no DNSCache.
See https://github.com/ooni/probe/issues/1376.
* fix: add unit tests for code making the dnscache
* fix(netx): make sure all tests pass
* chore: bump webconnectivity version
This is how I did it:
1. `git clone https://github.com/ooni/probe-engine internal/engine`
2. ```
(cd internal/engine && git describe --tags)
v0.23.0
```
3. `nvim go.mod` (merging `go.mod` with `internal/engine/go.mod`
4. `rm -rf internal/.git internal/engine/go.{mod,sum}`
5. `git add internal/engine`
6. `find . -type f -name \*.go -exec sed -i 's@/ooni/probe-engine@/ooni/probe-cli/v3/internal/engine@g' {} \;`
7. `go build ./...` (passes)
8. `go test -race ./...` (temporary failure on RiseupVPN)
9. `go mod tidy`
10. this commit message
Once this piece of work is done, we can build a new version of `ooniprobe` that
is using `internal/engine` directly. We need to do more work to ensure all the
other functionality in `probe-engine` (e.g. making mobile packages) are still WAI.
