When failpoint feature is disabled it throws away passed code so code
inside is not guaranteed to compile when feature is disabled. In this
particular case code is obsolete so removing it.
* [proxy] Add SCRAM auth
* [proxy] Implement some tests for SCRAM
* Refactoring + test fixes
* Hide SCRAM mechanism behind `#[cfg(test)]`
Currently we only use it in tests, so we hide all relevant
module behind `#[cfg(test)]` to prevent "unused item" warnings.
workspace_hack is needed to avoid recompilation when different crates
inside the workspace depend on the same packages but with different
features being enabled. Problem occurs when you build crates separately
one by one. So this is irrelevant to our CI setup because there we build
all binaries at once, but it may be relevant for local development.
this also changes cargo's resolver version to 2
* [proxy] Propagate most errors to user
This change enables propagation of most errors to the user
(e.g. auth and connectivity errors). Some of them will be
stripped of sensitive information.
As a side effect, most occurrences of `anyhow::Error` were
replaced with concrete error types.
* [proxy] Box weighty errors
This change makes most parts of the code asynchronous, except
for the `mgmt` subsystem (we're going to drop it anyway).

This introduces a new module to handle thread creation and shutdown.
All page server threads are now registered in a global hash map, and
there's a function to request individual threads to shut down gracefully.
Thread shutdown request is signalled to the thread with a flag, as well
as a Future that can be used to wake up async operations if shutdown is
requested. Use that facility to have the libpq listener thread respond
to pageserver shutdown, based on Kirill's earlier prototype
(https://github.com/zenithdb/zenith/pull/1088). That addresses
https://github.com/zenithdb/zenith/issues/1036, previously the libpq
listener thread would not exit until one more connection arrives.
This also eliminates a resource leak in the accept() loop. Previously,
we added the JoinHanlde of each new thread to a vector but old handles
for threads that had already exited were never removed.
Do it separately with SafekeeperPostgresCommand enum as a result. Since query is
always C string, switch postgres_backend process_query argument from Bytes to
&str.
Make passing ztli/ztenant id in safekeeper connection string optional; this is
needed for upcoming intra-safekeeper heartbeat cmd which is not bound to any
timeline.
We depends on rustls in postgres_backend anyway, so might as well use it
for all TLS stuff. Seems better to depend on only one library both from a
security point of view, and because fewer dependencies means less code to
compile. With this commit, we no longer depend on OpenSSL.
Git commit sha is displayed when --version flag is used and is written
to logs during service startup. Uses git_version crate when git is
available, and GIT_VERSION environment variable otherwise which is the case for docker
builds.
This change causes writer halves of a TLS stream to always flush after a
portion of bytes has been written by `std::io::copy`. Furthermore, some
cosmetic and minor functional changes are made to facilitate debug.
- perform checkpoint for each tenant repository.
- wait for the completion of all threads.
Add new option 'immediate' to 'pageserver stop' command to terminate the pageserver immediately.
