* test: use `T.TempDir` to create temporary test directory
This commit replaces `os.MkdirTemp` with `t.TempDir` in tests. The
directory created by `t.TempDir` is automatically removed when the test
and all its subtests complete.
Prior to this commit, temporary directory created using `os.MkdirTemp`
needs to be removed manually by calling `os.RemoveAll`, which is omitted
in some tests. The error handling boilerplate e.g.
defer func() {
if err := os.RemoveAll(dir); err != nil {
t.Fatal(err)
}
}
is also tedious, but `t.TempDir` handles this for us nicely.

We must close the open file descriptor otherwise the temporary file
cannot be cleaned up on Windows.

Annotations
This package provides an HTTP API for interacting with both annotations and
streams independently. The HTTP handlers are located in the transport
folder.
The code for interacting with the sqlite datastore is located in the
service.go
file. Definitions for the basic types & interfaces associated with
annotations and streams used throughout the platform are located in the
top-level influxdb
package, in the annotation.go
file.
Anatomy
An annotation is, at its simplest, a textual note on a range of time. The start
and stop time of that range can be the same point in time, which represents an
annotation at a single instance. Annotations can also have "stickers".
"Stickers" allow users to "tag" the annotation with further granularity for
filtering in key-value pairs. Some examples of sticker key-value pairs are:
"product: oss"
, "product: cloud"
, or "service: tasks"
, but keys and values
can be any string.
Every annotation belongs to a single "stream". A "stream" represents a logical
grouping of annotated events. Some examples of stream names are: "incidents"
,
"deployments"
, or "marketing"
, but can be any string. A stream can also have
a description to further clarify what annotated events may be expected in the
stream.
Use
Requested annotations may be filtered by stream name, stickers, and/or time range. Streams may also be retrieved, in order to view their description. If a stream is deleted, all annotations associated with that stream are deleted as well. Every annotation that is created must have a stream associated with it - if a stream name is not provided when creating an annotation, it will be assigned to the default stream.
