Currently, if the value of the l= tag is larger than the body, that
causes an out-of-bound access and the server crashes.
The RFC is clear that the value should be <= the size of the
canonicalized body.
This patch fixes the problem by validating the length appropriately, and
returning a permanent failure if it's invalid.
Thanks to John JEAN <john@wargan.com> who reported a similar issue
(fixed in a previous patch), which led to finding this bug.
Many of our tests rely on helpers that predate features which are now
available in the standard library.
This patch replaces them with the standard equivalents:
- MustTempDir/RemoveIfOk -> t.ArtifactDir() or t.TempDir() (depending on
whether it is useful to keep the data on request).
- GetFreePort + waitForServer -> opening the listeners before starting
the servers. To support this, localrpc.Server gains a Serve method. We
may re-introduce these in the future if more use cases appear.
- WaitFor and real-time timing checks -> testing/synctest.
- context.Background() -> t.Context().
- Benchmark b.N loops -> b.Loop().
- reflect.DeepEqual -> cmp.Diff, and proto.Equal for protobufs.
This patch contains the result of running `go fix ./...`, which applies
simplifications that make use of modern language features.
There are no logic or behaviour changes.
staticcheck found a couple of minor code cleanup improvements, like
unused variables or an out-of-order defer, mostly in tests.
This patch fixes those problems by making the necessary adjustments.
They're all fairly small, and should not change the logic in any
significant way.
The timestamp string in the t= and x= headers is an "unsigned decimal
integer", but time.Unix takes an int64. Today we parse it as uint64 and
then cast it, but this can cause issues with overflow and type
conversion.
This patch fixes that by parsing the timestamps as signed integers, and
then checking they're positive.
The current .gitignore pattern doesn't work when the private test cases
are a symlink, which can be convenient.
This patch fixes it by changing the pattern to match symlinks as well as
directories.
