With this, we no longer need to build two versions of 'pem' and 'base64'
crates. Introduces a duplicate version of 'time' crate, though, but it's
still progress.
- Remove batch_others/test_pgbench.py. It was a quick check that pgbench
works, without actually recording any performance numbers, but that
doesn't seem very interesting anymore. Remove it to avoid confusing it
with the actual pgbench benchmarks
- Run pgbench with "-n" and "-S" options, for two different workloads:
simple-updates, and SELECT-only. Previously, we would only run it with
the "default" TPCB-like workload. That's more or less the same as the
simple-update (-n) workload, but I think the simple-upload workload
is more relevant for testing storage performance. The SELECT-only
workload is a new thing to measure.
- Merge test_perf_pgbench.py and test_perf_pgbench_remote.py. I added
a new "remote" implementation of the PgCompare class, which allows
running the same tests against an already-running Postgres instance.
- Make the PgBenchRunResult.parse_from_output function more
flexible. pgbench can print different lines depending on the
command-line options, but the parsing function expected a particular
set of lines.
The PgProtocol.connect() function took extra options for username,
database, etc. Remove those options, and have a generic way for each
subclass of PgProtocol to provide some default options, with the
capability override them in the connect() call.
It was the only test that used the 'schema' argument to the connect()
function. I'm about to refactor the option handling and will remove
the special 'schema' argument altogether, so rewrite the test to not
use it.
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.
It originated from the fact that we were calling to fetch_full_index
without releasing the read guard, and fetch_full_index tries to acquire
read again. For plain mutex it is already a deeadlock, for RW lock
deadlock was achieved by an attempt to acquire write access later in the
code while still having active read guard up in the stack
This is sort of a bandaid because Kirill plans to change this code
during removal of an archiving mechanism
* [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.
* Add test for restore from WAL
* Fix python formatting
* Choose unused port in wal restore test
* Move recovery tests to zenith_utils/scripts
* Set LD_LIBRARY_PATH in wal recovery scripts
* Fix python test formatting
* Fix mypy warning
* Bump postgres version
* Bump postgres version
