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.

Imagine that you have a tenant with a single branch like this:
---------------==========>
^
gc horizon
where:
---- is the portion of the branch that is older than retention period
==== is the portion of the branch that is newer than retention period.
Before this commit, the sizing model included the logical size at the
GC horizon, but not the WAL after that. In particular, that meant that
on a newly created tenant with just one timeline, where the retention
period covered the whole history of the timeline, i.e. gc_cutoff was 0,
the calculated tenant size was always zero.
We now include the WAL after the GC horizon in the size. So in the
above example, the calculated tenant size would be the logical size
of the database the GC horizon, plus all the WAL after it (marked with
===).
This adds a new `insert_point` function to the sizing model, alongside
`modify_branch`, and changes the code in size.rs to use the new
function. The new function takes an absolute lsn and logical size as
argument, so we no longer need to calculate the difference to the
previous point. Also, the end-size is now optional, because we now
need to add a point to represent the end of each branch to the model,
but we don't want to or need to calculate the logical size at that
point.
- Pass through FAILPOINTS environment variable to the pageserver in
"neon_local pageserver start" command
- On startup, list any failpoints that were set with FAILPOINTS to the log
- Add optional "extra_env_vars" argument to the NeonPageserver.start()
function in the python fixture, so that you can pass FAILPOINTS
None of the tests use this functionality yet; that comes in a separate
commit.

Increse the pgbench runtimes even further. The theory is that when
there are many other tests running at the same time, one pgbench run
could take a long time until it generates enough layers for GC to kick
in.
I saw these from the build of the compute docker image in the CI
(compute-node-image-v15):
pagestore_smgr.c: In function 'neon_prefetch':
pagestore_smgr.c:1654:2: warning: ISO C90 forbids mixed declarations and code [-Wdeclaration-after-statement]

libpagestore.c:144:9: warning: variable 'wc' set but not used [-Wunused-but-set-variable]
144 | int wc;
| ^~
Harmless warnings, but let's be tidy.
In the passing, I added some "extern" to a few function declarations
that were missing them, and marked WalProposerSync as "static". Those
changes are also purely cosmetic.
Commit d013a2b227 changed the test, so that it fails if pgbench runs
to completion without triggering the failpoint. That has now happened
several times in the CI. That's not expected, so this needs some
investigation, but as a quick fix just make the pgbench runs longer so
that we're closer to the situation before commit d013a2b227.
See https://github.com/neondatabase/neon/issues/2856
This allows us to error out in the case where we request flush but the
flush loop is not running.
Before, we would only track whether it was started, but not when it
exited.
Better to use an enum with 3 states than a 2-state bool because then
the error message can answer the question whether we ever started
the flush loop or not.
In a CI run, I got a test failure because of this error in the log,
from the test_get_tenant_size_with_multiple_branches test:
ERROR gc_loop{tenant_id=f1630516d4b526139836ced93be0c878}: Gc failed, retrying in 2s: No such file or directory (os error 2)
There are known race conditions between GC and timeline deletion,
which surely caused that error. But if we didn't know the cause, it
would be pretty hard to debug without a stack trace.
* 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
Set correct `pg_distrib_dir` in `pageserver.toml` and in neon_local
`config`.
`test_forward_compatibility` shows flakiness during `neon_local pg
start`, so hopefully, the patch will help.

Feels like better testing on the env is needed later, maybe more e2e
tests have to be written (albeit we have download tests, so something
else happens here, tls issues?)
Thanks to the race condition, GC sometimes fails with "no such file or
directory" error, if the tenant is detached concurrently. That's a
known issue, but it didn't cause test failures until we started to
check for unexpected ERRORs in the log in commit 46d30bf054. We should
fix the race condition, of course, but until we do, let's silence the
failures.
Previously, if the failpoint was not reached for some reason, the test
would only fail because it would reach the 5 minute timeout we have on
all python tests. That's very subtle. Make it fail explicitly, if the
failpoint is not hit on each iteration of the loop.
Extracted from a larger PR, see

- Refactor the code a little bit, removing the silly for-loop over a
single element.
- Make it more clear in log messages that the errors are expectd
- Check for a more precise error message "Failed to load delta layer"
instead of just "extracting base backup failed".
