1. we now need to name the framework `.xcframework` otherwise
gomobile refuses to build a new framework for us ¯\_(ツ)_/¯
2. remove duplicate errno definition for iOS (iOS and darwin
are considered the same, therefore we don't need iOS defs)
Reference issue for this PR: https://github.com/ooni/probe/issues/1876
This diff WILL need to be forwardported to master.
This commit forward ports 74947dbbd12266c12a38fad51a70fc78a21720fd from
the `release/3.11` branch to `master`. Here's the original commit message:
- - -
Android is also Linux. The Android build fails because both
errno_linux.go and errno_android.go are compiled.
There's no difference between the files except into a comment
that mentions "linux" or "android".
Therefore, it's safe to remove the android-specific file
and just keep and use the linux-specific one.
Part of https://github.com/ooni/probe/issues/1863, where we're
forward porting ooni/go patches to go1.17.
I'm still trying to figure out whether I can build oonimkall
using the forward ported patches and this error prevents me
from building, because the build fails.
"やれやれだぜ"
Note that this patch WILL need to be forward ported to master.
This bug was previosuly reported to me by @hellais.
Because I did run `go generate ./internal/netxlite/...` we also
get for free updated certificates, which is OK.
On Windows, GetAddrInfoW is a syscall and the Go resolver does
not attempt to map errors beyond WSA_HOST_NOT_FOUND, which becomes
"no such host", which we map to "dns_nxdomain_error".
See https://github.com/golang/go/blob/go1.17.1/src/net/lookup_windows.go#L16.
To map more GetAddrInfoW errors, thus, we need to enhance our
error classifier to have system specific errors.
Then, we need to filter for the WSA errors that are most likely
to pop up and map them to OONI failures. Those are three:
- WSANO_DATA which we have from our own UDP resolver as well
and which we can map to `dns_no_answer`
- WSANO_RECOVERY which we don't have but existed for MK so
we will use `dns_non_recoverable_failure`, which was an MK error
- WSATRY_AGAIN which likewise we map to the error that MK
used to emit, so `dns_temporary_failure`
This diff should address https://github.com/ooni/probe/issues/1467.
I need to run test on Windows and I just discovered that:
1. the `errno_unix.go` filename does not mean anything because
`unix` is not a valid platform, so we need a filename for
each platform that we care about;
2. on Windows we need to use WSA prefixed names;
3. `i/e/session_psiphon.go` was not building because of the
migration from `netxlite/iox` to `netxlite`.
This diff attempts to fix all three issues.
The reference issue is https://github.com/ooni/probe/issues/1733,
because I was working on such an issue.
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.
