Simone Basso fd5405ade1 cleanup(all): stop using deprecated ioutil functions (#381)
Spotted while working on https://github.com/ooni/probe/issues/1417

See https://golang.org/pkg/io/ioutil/

Simone Basso 721ce95315 fix(all): introduce and use iox.CopyContext (#380)
* fix(all): introduce and use iox.CopyContext

This PR is part of https://github.com/ooni/probe/issues/1417.

In https://github.com/ooni/probe-cli/pull/379 we introduced a context
aware wrapper for io.ReadAll (formerly ioutil.ReadAll).

Here we introduce a context aware wrapper for io.Copy.

* fix(humanize): more significant digits

* fix: rename humanize files to follow the common pattern

* fix aligment

* fix test

Simone Basso 0fdc9cafb5 fix(all): introduce and use iox.ReadAllContext (#379)
* fix(all): introduce and use iox.ReadAllContext

This improvement over the ioutil.ReadAll utility returns early
if the context expires. This enables us to unblock stuck code in
case there's censorship confounding the TCP stack.

See https://github.com/ooni/probe/issues/1417.

Compared to the functionality postulated in the above mentioned
issue, I choose to be more generic and separate limiting the
maximum body size (not implemented here) from using the context
to return early when reading a body (or any other reader).

After implementing iox.ReadAllContext, I made sure we always
use it everywhere in the tree instead of ioutil.ReadAll.

This includes many parts of the codebase where in theory we don't
need iox.ReadAllContext. Though, changing all the places makes
checking whether we're not using ioutil.ReadAll where we should
not be using it easy: `git grep` should return no lines.

* Update internal/iox/iox_test.go

* fix(ndt7): treat context errors as non-errors

The rationale is explained by the comment documenting reduceErr.

* Update internal/engine/experiment/ndt7/download.go

* refactor(netx/dialer): hide implementation complexity

This follows the blueprint of `module.Config` and `nodule.New`
described at https://github.com/ooni/probe/issues/1591.

* fix: ndt7 bug where we were not using the right resolver

* fix(legacy/netx): clarify irrelevant implementation change

* fix: improve comments

* fix(hhfm): do not use dialer.New b/c it breaks it

Unclear to me why this is happening. Still, improve upon the
previous situation by adding a timeout.

It does not seem a priority to look into this issue now.

Simone Basso b7a6dbe47b refactor(netx/dialer): we can simplify the proxy (#371)
The socks5 factory always returns a DialContext capable dialer. We just
need to cast to obtain such a dialer.

Also, the code will use the DialContext if passed a dialer that
implements DialContext.

Write a test that proves my point.

Simone Basso adbde7246b refactor(netx): remove the self censorship mechanism (#364)
We're currently use jafar for QA and jafar is a better mechanism,
even though it is not portable outside of Linux.

This self censorship mechanism was less cool and added a bunch
of (also cognitive) complexity to netx.

If we ever want to go down a self censorship like road, we probably
want to do as little work as possible in the problem and as much
work as possible inside a helper like jafar.

* 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

This diff implements part of the release checklist at https://github.com/ooni/probe/issues/1439. The plan is to bless a beta release and use it for further testing on Android devices. Afterward, we need to apply some extra changes to the `cli` (including https://github.com/ooni/probe-cli/pull/314 and https://github.com/ooni/probe-cli/pull/312). Finally, we will bless a full 3.10.0 release.

Simone Basso 2ca9496c04 Release: update user-agent, bundled CA, version number (#281)
* chore: update the user-agent we use

Part of the check-list at https://github.com/ooni/probe/issues/1369.

* chore: set version to 3.9.0

See https://github.com/ooni/probe/issues/1369

* chore: run go generate ./...

This is meant to update the bundled CA. We have heard of issues with
our bundled CA, but it seems there have been no changes upstream.

The website https://curl.se/docs/caextract.html still lists as the
last change the one done on Jan 19, 2021, which is the version of
the CA that we're currently bundling.

For the sake of continuing with the release process, I am going
to further investigate the CA once the release is done.

* 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.

Simone Basso fc19c9901a fix(webconnectivity): expose network events (#258)
* 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.

Simone Basso 2ef5fb503a fix(webconnectivity): allow measuring https://1.1.1.1 (#241)
* 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.

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.

* 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?

Simone Basso d57c78bc71 chore: merge probe-engine into probe-cli (#201)
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.
