* Fix https://github.com/neondatabase/neon/issues/1854
* Never log Safekeeper::conninfo in walproposer as it now contains a secret token
* control_panel, test_runner: generate and pass JWT tokens for Safekeeper to compute and pageserver
* Compute: load JWT token for Safekepeer from the environment variable. Do not reuse the token from
pageserver_connstring because it's embedded in there weirdly.
* Pageserver: load JWT token for Safekeeper from the environment variable.
* Rewrite docs/authentication.md
Which ought to replace etcd. This patch only adds the binary and adjusts
Dockerfile to include it; subsequent ones will add deploy of helm chart and the
actual replacement.
It is a simple and fast pub-sub message bus. In this patch only safekeeper
message is supported, but others can be easily added.
Compilation now requires protoc to be installed. Installing protobuf-compiler
package is fine for Debian/Ubuntu.

- Refactor the way the WalProposerMain function is called when started
with --sync-safekeepers. The postgres binary now explicitly loads
the 'neon.so' library and calls the WalProposerMain in it. This is
simpler than the global function callback "hook" we previously used.
- Move the WAL redo process code to a new library, neon_walredo.so,
and use the same mechanism as for --sync-safekeepers to call the
WalRedoMain function, when launched with --walredo argument.
- Also move the seccomp code to neon_walredo.so library. I kept the
configure check in the postgres side for now, though.
Instead of spawning helper threads, we now use Tokio tasks. There
are multiple Tokio runtimes, for different kinds of tasks. One for
serving libpq client connections, another for background operations
like GC and compaction, and so on. That's not strictly required, we
could use just one runtime, but with this you can still get an
overview of what's happening with "top -H".
There's one subtle behavior in how TenantState is updated. Before this
patch, if you deleted all timelines from a tenant, its GC and
compaction loops were stopped, and the tenant went back to Idle
state. We no longer do that. The empty tenant stays Active. The
changes to test_tenant_tasks.py are related to that.
There's still plenty of synchronous code and blocking. For example, we
still use blocking std::io functions for all file I/O, and the
communication with WAL redo processes is still uses low-level unix
poll(). We might want to rewrite those later, but this will do for
now. The model is that local file I/O is considered to be fast enough
that blocking - and preventing other tasks running in the same thread -
is acceptable.
* Add submodule postgres-15
* Support pg_15 in pgxn/neon
* Renamed zenith -> neon in Makefile
* fix name of codestyle check
* Refactor build system to prepare for building multiple Postgres versions.
Rename "vendor/postgres" to "vendor/postgres-v14"
Change Postgres build and install directory paths to be version-specific:
- tmp_install/build -> pg_install/build/14
- tmp_install/* -> pg_install/14/*
And Makefile targets:
- "make postgres" -> "make postgres-v14"
- "make postgres-headers" -> "make postgres-v14-headers"
- etc.
Add Makefile aliases:
- "make postgres" to build "postgres-v14" and in future, "postgres-v15"
- similarly for "make postgres-headers"
Fix POSTGRES_DISTRIB_DIR path in pytest scripts
* Make postgres version a variable in codestyle workflow
* Support vendor/postgres-v15 in codestyle check workflow
* Support postgres-v15 building in Makefile
* fix pg version in Dockerfile.compute-node
* fix kaniko path
* Build neon extensions in version-specific directories
* fix obsolete mentions of vendor/postgres
* use vendor/postgres-v14 in Dockerfile.compute-node.legacy
* Use PG_VERSION_NUM to gate dependencies in inmem_smgr.c
* Use versioned ECR repositories and image names for compute-node.
The image name format is compute-node-vXX, where XX is postgres major version number.
For now only v14 is supported.
Old format unversioned name (compute-node) is left, because cloud repo depends on it.
* update vendor/postgres submodule url (zenith->neondatabase rename)
* Fix postgres path in python tests after rebase
* fix path in regress test
* Use separate dockerfiles to build compute-node:
Dockerfile.compute-node-v15 should be identical to Dockerfile.compute-node-v14 except for the version number.
This is a hack, because Kaniko doesn't support build ARGs properly
* bump vendor/postgres-v14 and vendor/postgres-v15
* Don't use Kaniko cache for v14 and v15 compute-node images
* Build compute-node images for different versions in different jobs

To flush inmemory layer eventually when no new data arrives, which helps
safekeepers to suspend activity (stop pushing to the broker). Default 10m should
be ok.
Reorganize existing READMEs and other documentation files into mdbook
format. The resulting Table of Contents is a mix of placeholders for
docs that we should write, and documentation files that we already had,
dropped into the most appropriate place.
Update the Pageserver overview diagram. Add sections on thread
management and WAL redo processes.
Add all the RFCs to the mdbook Table of Content too.
Per github issue #1979
+ neondatabase/cloud#1103
This adds a couple of control endpoints to simplify compute state
discovery for control-plane. For example, now we may figure out
that Postgres wasn't able to start or basebackup failed within
seconds instead of just blindly polling the compute readiness
for a minute or two.
Also we now expose startup metrics (time of the each step: basebackup,
sync safekeepers, config, total). Console grabs them after each
successful start and report as histogram to prometheus and grafana.
OpenAPI spec is added and up-tp date, but is not currently used in the
console yet.
Commit edba2e97 renamed pageserver/README to pageserver/README.md, but
forgot to update links to it. Fix.
Rename libs/postgres_ffi/README and safekeeper/README files to also
have the the .md extension, so that github can render them nicely.
Quote ascii-diagram in safekeeper/README.md so that it renders
correctly.
