As part of MySQL 8.4 release, terminology about Master/Slave has been replaced. During snapshot, we issue SHOW MASTER STATUS to gather the current binlog position. This command has been replaced with SHOW BINARY LOG STATUS by mysql/mysql-server@6e2c577 . Unfortunately, the new terminology is not available on 8.0 series, so we need to check the server version and conditionally adjust the query we issue. Also, adjusted the checksum query to use the new terminology of source_binlog_checksum is compatible with 8.0 and 8.4.

If you have an empty directory under the `benches_data/<db>`, you will
get a confusing error message like this:
```
No schema for benchmark {name}
```
It ends up being that you don't have as schema file (suffixed with
`.sql`) in on of the subdirectories. The error message fails to insert
the bench test name (from it's folder name), and thus unclear. This CL
just fixes that error message a bit.

If we are no longer replicating a table, e.g. due to the presence of `--replication-tables-ignore`, we will register it as a non-replicated relation on the controller. We will then later try to drop the base table, but will instead only drop the non-replicated relation registration, leaving the base table around. Additionally, if the table was only partially snapshotted, we could later error when trying to retrieve its replication offset after snapshotting has supposedly finished (but we've haven't been replicating that table). With this change, we drop leftover tables before registering non-replicated relations, so that attempting to drop the base table actually does so.

The MySQL min and max positions can be far apart. This happens on unbalance workloads, where for example one of the tables do not receive updates for a long period of time, like a config table that might be static. This causes the MySQL min position to fall behind the max position, in case of a restart, the replicator has to catch up starting from the min position. This causes a lot on unnecessary data to be re-streamed. Currently we only update the min position when MySQL rotates the binary log and we receive a EventType::ROTATE_EVENT. Adjusting the position on all tables might be costly if the installation has a lot of tables. This commit adjust the replicator to adjust table position on a fixed interval. This interval is hardcoded to 10 seconds. The event we act on is either the EventType::QueryEvent when we receive a "COMMIT" query, or the EventType::XidEvent. They are virtually the same thing (a commit), but depending on the storage engine MySQL reports a query COMMIT or an XID event. We also report the position once we have finished the initial catch up phase.

Previously, the views synchronizer only checked the server for views for queries that were in the "pending" state. This meant that if the migration handler set a query's state to "dry run succeeded" before the views synchronizer had a chance to check the server for a view, the query would be stuck in the "dry run succeeded" state forever, even if a view for the query did indeed exist already. This commit fixes the issue by having the views synchronizer check the server for views for queries in *either* the "pending" or "dry run succeeded" states. In order to prevent the views synchronizer from rechecking every query with status "dry run succeeded" over and over again, a "cache" has been added to the views synchronizer to keep track of which queries have already been checked. While working on this, I also noticed that it was possible for the following sequence of events to occur: - Migration handler sees that a query is pending and kicks off a dry run migration - Views synchronizer finds a view on the server for the same query and sets the status to "successful" - Migration handler finishes the dry run migration for the query and overwrites the status as "dry run succeeded" This could lead to a situation where a query that was previously (correctly) labeled as "successful" is moved back to the "dry run succeeded" state. To fix the issue, this commit updates the migration handler to only write the "dry run succeeded" status if the query's status is still "pending" after the dry run is completed. Release-Note-Core: Fixed a bug where queries that already had caches were sometimes stuck in the `SHOW PROXIED QUERIES` list Change-Id: Ie5faa100158fc80c906d8ad5cb897d8a02a07be9 Reviewed-on: https://gerrit.readyset.name/c/readyset/+/7442 Tested-by: Buildkite CI Reviewed-by: Jason Brown <[email protected]>

This reverts commit 1cde153ceafb59901ad133317b85d357573cf2df. Reason for revert: While this CL was attempting to address a reasonable conern (under-eviction), it unfornately goes too far in the opposite direction and over-evicts as well as unnecessarily burning through additional CPU cycles. As background, when we determine we need to evict some bytes in `do_eviction()`, we send messages to domains requesting them to evict some number of bytes. Those messsages are sent _asynchonously_, and any reciprocating updates to the domain sizes are recieved _asynchronously_. This CL introduced a loop around that core eviction functionality, assumably thinking that eviction is synchronous. As there is nothing blocking or delaying each iteration of the loop, it would hammer away sending async eviction messages until the domain sizes fell below the threshold, but because we sent more eviction requests than necessary, we over-evicted. This is compounded by the call to `MemoryTracker::allocated_bytes()` on each loop iteration. That function must update all jemalloc stats by updating an epoch value inside of jemalloc, which turns out be an expensive operation.

This commits adds proper collation support for CHAR and BINARY columns in MySQL. CHAR columns should be right padded with spaces to the column length when storing them and BINARY should right pad zeros. This commit fixes the issue at snapshot - During snapshot we do a logical dump of data. MySQL removes padding spaces from CHAR columns when retrieving them. So, we need to take the column collation into consideration when storing them. One gotcha is with ENUM/SET columns, they are retrieved as Strings(MYSQL_TYPE_STRING), but we should not pad them. During CDC, we need to retrieve proper metadata from TME in order to validate if padding is necessary or not. This commit also fixes an issue when storing BINARY columns. We were storing them as TinyText/Text if the binary representation of the columns was a valid UTF-8 string. This is not correct. We should store them as ByteArray. Test cases were written taking into consideration a mix of characters from different bytes, like mixing ASCII and UTF-8 characters from 2nd and 3rd bytes. Note: MySQL uses the terminology of charset and collation interchangeably. In the end everything is stored as collation ID, which can be used to determine the charset and collation.

At some point, the macOS security framework changed enough such that it
apparently cannot be convinced to accept a TLS cert without a password.
That meant that some tests involving TLS were failing on macs because
our test cert had no password on it. This update creates a new cert
with password "password", and updates the tests that use it.
Furthermore, OpenSSL 3 dropped compatibility with certain encryption
ciphers by default, meaning that pkcs12 certs created with it couldn't
be verified by the macOS security framework. The web-recommended
solution is to run `openssl pkcs12` with the `-legacy` option.
Unfortunately, while solving the problem for macOS, this produced a cert
that was too out-of-date for OpenSSL3 on linux. More specific cipher
selection per the Magic Incantations(tm) below generates a cert that
will pass tests on both macOS *and* Linux... but may not be safe for
any other purpose. Apply only to affected area. In case of hemorrhage,
seek emergency medical help immediately.
For reference, the commands below were used to create this cert on macOS
using OpenSSL 3.3.1 installed with `homebrew`:
```
# Make a new private key
openssl genrsa -out private.key 2048
# Generate a signing request.
openssl req -new -key private.key -out cert.csr
# Generate an x5509 cert from the signing request (good for 10 years)
openssl x509 -req -days 3650 -in cert.csr -signkey private.key \

# Export the pkcs12 file with password "password"

Add snapshot type to mysql connector. Snapshot type defines how the snapshot will be taken. It can be either a key based (Primary Key / Unique Key) or a full table scan snapshot.

Adjust the MySQL snapshot to use the new snapshot type. The snapshot type checks if table has a primary key or unique key and uses it to define batches to query the table, making it less intrusive, specially for large tables. In case the table does not have a primary key or unique key, the snapshot will do a full table scan. Fixes: REA-4477 Fixes: #1303 Release-Note-Core: Enhance MySQL snapshot to use Primary Key or unique key when available. This makes the snapshot less intrusive than a `SELECT *` (Full Table Scan) for large tables.

Insufficient committing and testing of the previous patch resulted in code that didn't actually work. The two oversights were: failing to check for hex before integers and an incorrect attempt to handle odd-length literals in Postgres, which was checking the length of the returned bytes, not the length of the literal. (Some of this code has been written so as to help support odd-length literals in the future, but they don't currently work. The first obvious problem is that the return type here returns bytes, not bits.)

We have out own implementation of Datetime/Timestamp called TimestampTZ. This object has a 3 bytes bitmap that gives us better control over printing date only, timestamp with tz even if tz is zero and microsecond precision even if it is zero. Currently we were converting the TimestampTZ to NaiveDateTime and then printing it. This was causing some issues with MySQL and datetime. NaiveDateTime has an inner object called NaiveTime to represent time. When printing naive time, if the microsecond is zero, it is not printed [0]. For MySQL, if the Datetime column has the optional microsecond precision set, we need to print the microsecond even if it is zero, causing a mismatch between the readyset and MySQL. This commit changes the display object for datetime/tz columns to TimestampTZ and implement text and binary protocol trait for it.

Currently, `dataflow-state::State` has a `tear_down` function. This was added in `7b5324d3aaa41a85f8c0380782d8e8efb53be7c7` to throw away the state of a node when removing it form the dataflow graph. This has only been used to remove rocksdb files from base table when we stop replicating them. When we added custom WAL flushing behavior, in b34f871bb1da26434e88534a049c45c58d20815a, code was added to shut down the WAL flushing thread. However, it was added to the `PersistentState::tear_down()` implementation, and thus would only be called when the node was removed from the graph. We need that thread to be run on process shut down, as well, else Readyset can core dump on normal process exit. This CL adds a `State::shut_down` function that can be called under normal exit situations. Machinery to actually invoke it will be added in a followup CL.

When a worker receives a message on the `shutdown_tx` channel, we now plumb through the event to the the new `State::shut_down` function on each node of the dataflow graph. This allows Readyset to properly shut down the rocksdb WAL flushing thread when a domain is killed (due to other error) or when the process is exiting. This CL also raises the priority of listening for events on the `shutdown_tx` within `Worker::run()`, by adding the `biased` tag before that block in the `select!`. We do this in several places in Readyset, most notable in the adapter. Release-Note-Core: Now properly shutting down the rocksdb WAL at process exit.
