When preparing a tutorial for netxlite, I figured it is easier
to tell people "hey, this is the package you should use for all
low-level networking stuff" rather than introducing people to
a set of packages working together where some piece of functionality
is here and some other piece is there.
Part of https://github.com/ooni/probe/issues/1591
We need still to add similar wrappers to internal/netxlite but we
will adopt a saner approach to error wrapping this time.
See https://github.com/ooni/probe/issues/1591
The legacy part for now is internal/errorsx. It will stay there until
I figure out whether it also needs some extra bug fixing.
The good part is now in internal/netxlite/errorsx and contains all the
logic for mapping errors. We need to further improve upon this logic
by writing more thorough integration tests for QUIC.
We also need to copy the various dialer, conn, etc adapters that set
errors. We will put them inside netxlite and we will generate errors in
a way that is less crazy with respect to the major operation. (The
idea is to always wrap, given that now we measure in an incremental way
and we don't measure every operation together.)

* refactor(atomicx): move outside the engine package
After merging probe-engine into probe-cli, my impression is that we have
too much unnecessary nesting of packages in this repository.
The idea of this commit and of a bunch of following commits will instead
be to reduce the nesting and simplify the structure.
While there, improve the documentation.
* fix: always use the atomicx package
For consistency, never use sync/atomic and always use ./internal/atomicx
so we can just grep and make sure we're not risking to crash if we make
a subtle mistake on a 32 bit platform.
While there, mention in the contributing guidelines that we want to
always prefer the ./internal/atomicx package over sync/atomic.
* fix(atomicx): remove unnecessary constructor
We don't need a constructor here. The default constructed `&Int64{}`
instance is already usable and the constructor does not add anything to
what we are doing, rather it just creates extra confusion.
* cleanup(atomicx): we are not using Float64
Because atomicx.Float64 is unused, we can safely zap it.
* cleanup(atomicx): simplify impl and improve tests
We can simplify the implementation by using defer and by letting
the Load() method call Add(0).
We can improve tests by making many goroutines updated the
atomic int64 value concurrently.
* refactor(fsx): can live in the ./internal pkg
Let us reduce the amount of nesting. While there, ensure that the
package only exports the bare minimum, and improve the documentation
of the tests, to ease reading the code.
* refactor: move runtimex to ./internal
* refactor: move shellx into the ./internal package
While there, remove unnecessary dependency between packages.
While there, specify in the contributing guidelines that
one should use x/sys/execabs instead of os/exec.
* refactor: move ooapi into the ./internal pkg
* refactor(humanize): move to ./internal and better docs
* refactor: move platform to ./internal
* refactor(randx): move to ./internal
* refactor(multierror): move into the ./internal pkg
* refactor(kvstore): all kvstores in ./internal
Rather than having part of the kvstore inside ./internal/engine/kvstore
and part in ./internal/engine/kvstore.go, let us put every piece of code
that is kvstore related into the ./internal/kvstore package.
* fix(kvstore): always return ErrNoSuchKey on Get() error
It should help to use the kvstore everywhere removing all the
copies that are lingering around the tree.
* sessionresolver: make KVStore mandatory
Simplifies implementation. While there, use the ./internal/kvstore
package rather than having our private implementation.
* fix(ooapi): use the ./internal/kvstore package
* fix(platform): better documentation
* feat: create tunnel inside NewSession
We want to create the tunnel when we create the session. This change
allows us to nicely ignore the problem of creating a tunnel when we
already have a proxy, as well as the problem of locking. Everything is
happening, in fact, inside of the NewSession factory.
Modify miniooni such that --tunnel is just syntactic sugar for
--proxy, at least for now. We want, in the future, to teach the
tunnel to possibly use a socks5 proxy.
Because starting a tunnel is a slow operation, we need a context in
NewSession. This causes a bunch of places to change. Not really a big
deal except we need to propagate the changes.
Make sure that the mobile code can create a new session using a
proxy for all the APIs we support.
Make sure all tests are still green and we don't loose coverage of
the various ways in which this code could be used.
This change is part of https://github.com/ooni/probe/issues/985.
* changes after merge
* fix: only keep tests that can hopefully work
While there, identify other places where we should add more
tests or fix integration tests.
Part of https://github.com/ooni/probe/issues/985
* 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
* 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
* chore: update dependencies
* chore: update user agent for measurements
* chore: we're now at v3.6.0
* chore: update assets
* chore: update bundled CA
* fix: address some goreportcard.com warnings
* fix(debian/changelog): zap release that breaks out build scripts
We're forcing the content of changelog with `dch`, so it's fine to
not have any specific new release in there.
* fix: make sure tests are passing locally
Notably, I removed a chunk of code where we were checking for network
activity. Now we don't fetch the databases and it's not important. Before,
it was important because the databases are ~large.
* fix: temporarily comment out riseupvn integration tests
See https://github.com/ooni/probe/issues/1354 for work aimed at
reducing the rate of false positives (thanks @cyBerta!)
* MVP of a signal messenger test
* Add minimal signal test unit tests
* Add Signal test to the im nettest group
* Add test for https://sfu.voip.signal.org/
* Fix bug in client-side determination of blocking status
* Add uptime.signal.org to the test targets
* Add more tests
* Check for invalid CA being passed
* Check that the update function works as expected
* Update internal/engine/experiment/signal/signal_test.go

* fix: back out URL we shouldn't have changed
When merging probe-engine into probe-cli, we changed too many URLs
and some of them should not have been changed.
I noticed this during the review of Signal and I choose to add
this commit to revert such changes.
While there, make sure the URL of the experiment is OK.
* fix(signal): reach 100% of coverage
Just so that we can focus on areas of the codebase where we need
more coverage, let us avoid missing an easy line to test.

* refactor: move more commands to internal/cmd
Part of https://github.com/ooni/probe/issues/1335.
We would like all commands to be at the same level of engine
rather than inside engine (now that we can do it).
* fix: update .gitignore
* refactor: also move jafar outside engine
* We should be good now?
* refactor: start building an Android package
Part of https://github.com/ooni/probe/issues/1335.
This seems also a good moment to move some packages out of the
engine, e.g., oonimkall. This package, for example, is a consumer
of the engine, so it makes sense it's not _inside_ it.
* fix: committed some stuff I didn't need to commit
* fix: oonimkall needs to be public to build
The side effect is that we will probably need to bump the major
version number every time we change one of these APIs.
(We can also of course choose to violate the basic guidelines of Go
software, but I believe this is bad form.)
I have no problem in bumping the major quite frequently and in
any case this monorepo solution is convinving me more than continuing
to keep a split between engine and cli. The need to embed assets to
make the probe more reliable trumps the negative effects of having to
~frequently bump major because we expose a public API.
* fix: let's not forget about libooniffi
Honestly, I don't know what to do with this library. I added it
to provide a drop in replacement for MK but I have no idea whether
it's used and useful. I would not feel comfortable exposing it,
unlike oonimkall, since we're not using it.
It may be that the right thing to do here is just to delete the
package and reduce the amount of code we're maintaining?
* woops, we're still missing the publish android script
* fix(publish-android.bash): add proper API key
* ouch fix another place where the name changed
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.
