Christian Schwarz	87cd2bae77	introduce LaunchTimestamp to identify process restarts ... This patch adds a LaunchTimestamp type to the `metrics` crate, along with a `libmetric_` Prometheus metric. The initial user is pageserver. In addition to exposing the Prometheus metric, it also reproduces the launch timestamp as a header in the API responses. The motivation for this is that we plan to scrape the pageserver's /v1/tenant/:tenant_id/timeline/:timeline_id/layer HTTP endpoint over time. It will soon expose access metrics (#3496) which reset upon process restart. We will use the pageserver's launch ID to identify a restart between two scrape points. However, there are other potential uses. For example, we could use the Prometheus metric to annotate Grafana plots whenever the launch timestamp changes.	2023-02-03 18:12:17 +01:00
Kirill Bulatov	bce4233d3a	Rework Cargo.toml dependencies (#3322) ... * Use workspace variables from cargo, coming with rustc [1.64](https://github.com/rust-lang/rust/blob/master/RELEASES.md#version-1640-2022-09-22) See https://doc.rust-lang.org/nightly/cargo/reference/workspaces.html#the-package-table and https://doc.rust-lang.org/nightly/cargo/reference/workspaces.html#the-dependencies-table sections. Now, all dependencies in all non-root `Cargo.toml` files are defined as ``` clap.workspace = true ``` sometimes, when extra features are needed, as ``` bytes = {workspace = true, features = ['serde'] } ``` With the actual declarations (with shared features and version numbers/file paths/etc.) in the root Cargo.toml. Features are additive: https://doc.rust-lang.org/nightly/cargo/reference/specifying-dependencies.html#inheriting-a-dependency-from-a-workspace * Uses the mechanism above to set common, 2021, edition and license across the workspace * Mechanically bumps a few dependencies * Updates hakari format, as it suggested: ``` work/neon/neon kb/cargo-templated ❯ cargo hakari generate info: no changes detected info: new hakari format version available: 3 (current: 2) (add or update `dep-format-version = "3"` in hakari.toml, then run `cargo hakari generate && cargo hakari manage-deps`) ```	2023-01-13 18:13:34 +02:00
