## Problem
Existing dependencies didn't work on Fedora 39 (python 3.12)
## Summary of changes
- Update pyyaml 6.0 -> 6.0.1
- Update yarl 1.8.2->1.9.4
- Update the `dnf install` line in README to include dependencies of
python packages (unrelated to upgrades, just noticed absences while
doing fresh pysync run)
`neon_local endpoint` subcommand currently allows creating two primary
endpoints for the same branch which leads to shutdown of both endpoints
`neon_local endpoint start` new behavior:
1. Fail if endpoint doesn't exist
2. Fail if two primary conflict detected

## Problem
In 83e7e5dbbd dependencies were only
updated for Mac users. Without libicu, postgres 16 build fails.
## Summary of changes
Update dependencies on Ubuntu and fedora to include libicu.
This adds PostgreSQL 16 as a vendored postgresql version, and adapts the
code to support this version.
The important changes to PostgreSQL 16 compared to the PostgreSQL 15
changeset include the addition of a neon_rmgr instead of altering Postgres's
original WAL format.

## Problem
When setting up for the first time I hit a couple of nits running tests:
- It wasn't obvious that `openssl` and `poetry` were needed (poetry is
mentioned kind of obliquely via "dependency installation notes" rather
than being in the list of rpm/deb packages to install.
- It wasn't obvious how to get the tests to run for just particular
parameters (e.g. just release mode)
## Summary of changes
Add openssl and poetry to the package lists.
Add an example of how to run pytest for just a particular build type and
postgres version.
## Problem
1. The local endpoints provision 2 ports (postgres and HTTP) which means
the migration_check endpoint has a different port than what the setup
implies
2. psycopg2-binary 2.9.3 has a deprecated poetry config and doesn't
install.
## Summary of changes
Update psycopg2-binary and update the endpoint ports in the readme

We use the term "endpoint" in for compute Postgres nodes in the web UI
and user-facing documentation now. Adjust the nomenclature in the code.
This changes the name of the "neon_local pg" command to "neon_local
endpoint". Also adjust names of classes, variables etc. in the python
tests accordingly.
This also changes the directory structure so that endpoints are now
stored in:
.neon/endpoints/<endpoint id>
instead of:
.neon/pgdatadirs/tenants/<tenant_id>/<endpoint (node) name>
The tenant ID is no longer part of the path. That means that you
cannot have two endpoints with the same name/ID in two different
tenants anymore. That's consistent with how we treat endpoints in the
real control plane and proxy: the endpoint ID must be globally unique.
Add a condition to switch walreceiver connection to safekeeper that is
located in the same availability zone. Switch happens when commit_lsn of
a candidate is not less than commit_lsn from the active connection. This
condition is expected not to trigger instantly, because commit_lsn of a
current connection is usually greater than commit_lsn of updates from
the broker. That means that if WAL is written continuously, switch can
take a lot of time, but it should happen eventually.
Now protoc 3.15+ is required for building neon.
Fixes https://github.com/neondatabase/neon/issues/3200
The control plane currently only supports EdDSA. We need to either teach
the storage to use EdDSA, or the control plane to use RSA. EdDSA is more
modern, so let's use that.
We could support both, but it would require a little more code and tests,
and we don't really need the flexibility since we control both sides.
Follow-up of https://github.com/neondatabase/neon/pull/3270 which made
an example from main README.md not working.
Fixes that, by adding a way to specify a default tenant now and modifies
the basic neon_local test to start postgres and check branching.
Not all neon_local commands are implemented, so not all README.md
contents is tested yet.
- Change "WAL service" to "safekeepers" in the architecture section. The
safekeepers together form the WAL service, but we don't use that term
much in the code.
- Replace the short list of pageserver components with a link /docs. We
have more details there.
- Add "Other resources" to Documention section, with links to some blog
posts and a video presentation.
- Remove notice at the top about the Zenith -> Neon rename. There are
still a few references to Zenith in the codebase, but not so many that
we would need to call it out at the top anymore.
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.

* Poll more frequently when waiting for process start/stop. This
speeds up startup and shutdown in tests. We did this already in
commit 52ce1c9d53, which reduced the interval to 100 ms, but it was
inadvertently increased back to 500 ms in commit d42700280f. Reduce
it to 100 ms again, for both start and stop operations.
* Harmonize the start and stop loops, printing the dots and notices
the same way in both. I considered extracting the logic to a
separate retry-function that takes a closure as argument that does
the polling, but as long as we only have two copies, the code
duplication isn't that bad.
* Remove newline after "Starting pageserver" and "Starting etcd"
messages, so that the progress-indicator dots that are printed once
a second are printed on the same line. Before:
Starting pageserver at '127.0.0.1:64000' in '.neon'
...
pageserver started, pid: 2538937
After:
Starting pageserver at '127.0.0.1:64000' in '.neon'...
pageserver started, pid: 2538937
The "Starting safekeeper" message already got this right.
* Update example output in README.md to match
* 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

* Update make instructions for release and debug build. Update PostgreSQL glossary to proper version (14)
* Continued cleanup of build instructions including removal of redundancies
There's a lot of renaming left to do in the code and docs, but this is
a start. Our binaries and many other things are still called "zenith",
but I didn't change those in the README, because otherwise the
examples won't work. I added a brief note at the top of the README to
explain that we're in the process of renaming, until we've renamed
everything.
Mainly because it has better support for installing the packages from
different python versions.
It also has better dependency resolver than Pipenv. And supports modern
standard for python dependency management. This includes usage of
pyproject.toml for project specific configuration instead of per
tool conf files. See following links for details:
https://pip.pypa.io/en/stable/reference/build-system/pyproject-toml/https://www.python.org/dev/peps/pep-0518/
