This is required to implement websteps, which is currently tracked
by https://github.com/ooni/probe/issues/1733.
We introduce the concept of async runner. An async runner will
post measurements on a channel until it is done. When it is done,
it will close the channel to notify the reader about that.
This change causes sync experiments now to strictly return either
a non-nil measurement or a non-nil error.
While this is a pretty much obvious situation in golang, we had
some parts of the codebase that were not robust to this assumption
and attempted to submit a measurement after the measure call
returned an error.
Luckily, we had enough tests to catch this change in our assumption
and this is why there are extra docs and tests changes.
The current implementation assumes the user has already installed tor
on the current system. If tor is not present, the experiment fails.
This is meant to be the first version of this experiment.
We are going to add more functionality in subsequent revisions of
this experiment, once we've collected more feedback.
Reference issue: https://github.com/ooni/probe/issues/1565.
Here's the spec PR: https://github.com/ooni/spec/pull/218.
Here's the issue tracking future work: https://github.com/ooni/probe/issues/1686
* ongoing
* while there, make sure we test everything
* reorganize previous commit
* ensure we have reasonable coverage in session
The code in here would be better with unit tests. We have too many
integration tests and the tests overall are too slow. But it's also
true that I should not write a giant diff as part of this PR.
* fix(pkg.go.dev): import a subpackage containing the assets
We're trying to fix this issue that pkg.go.dev does not build.
Thanks to @hellais for this very neat idea! Let's keep our
fingers crossed and see whether it fixes!
* feat: use embedded geoip databases
Closes https://github.com/ooni/probe/issues/1372.
Work done as part of https://github.com/ooni/probe/issues/1369.
* fix(assetsx): add tests
* feat: simplify and just vendor uncompressed DBs
* remove tests that seems not necessary anymore
* fix: run go mod tidy
* Address https://github.com/ooni/probe-cli/pull/260/files#r605181364
* rewrite a test in a better way
* fix: gently cleanup the legacy assetsdir
Do not remove the whole directory with brute force. Just zap the
files whose name we know. Then attempt to delete the legacy directory
as well. If not empty, just fail. This is fine because it means the
user has stored other files inside the directory.
* fix: create .miniooni if missing
We use ExperimentOrchestraClient in several places to help us
calling probe-services APIs. We need to call CheckIn because we
want to use CheckIn in InputLoader.
(We also want to remove the URLs API, but that is not something
doable now, since the mobile app is still using this API via
the wrappers at pkg/oonimkall.)
Work part of https://github.com/ooni/probe/issues/1299.
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.
