• 8576: Change LateBindQueryist to use mysql.NewSalt()
  In preparation for refactoring the auth server interface in Vitess/GMS, this change makes LateBindQueryist call mysql.NewSalt() directly, instead of relying on the NewSalt() method on the MySQLDb instance (which internally calls mysql.NewSalt()).

• 2739: Embed the embedded.Tracer into memTracer, to fulfil the updated interface
  I was trying to use this project go-mysql-server as a dependency alongside github.com/grafana/grafana-plugin-sdk-go/data. But the latter project depends on:
  • go.opentelemetry.io/otel v1.31.0
  • go.opentelemetry.io/otel/trace v1.31.0
    When I updated my go modules with go mod tidy I started to hit a compilation error:

  If:

  • A value "A.b" within this object was modified
  • The previous chunk was also modified
    Then the differ would incorrectly report that the entire "A" object had been modified, instead of the sub-value "A.b"
    This could then lead to situations where the merge cannot be auto-resolved, because the differ claims that an object has been modified divergently, when it's actually two unrelated fields in the object that have been modified.
    This PR fixes that scenario by properly detecting when the next chunk marks the start of an object.

• 8534: Fix issue where JSON diff would fail under specific circumstances.
  If all of the following are true during a JSON diff operation:
  1. One document fits in a single chunk and the other doesn't
  2. The location of the chunk boundary in the larger document is also present in the smaller document. (It doesn't correspond to a location that was added or removed)
  3. The chunk boundary falls at the end of a value in the document (before the next key or comma/right brace/etc)
     Then the differ would fail to advance the prolly tree cursor and would incorrectly see the larger document as corrupt.
     This fixes that issue and improves the error messaging to make it seem less like the database is corrupt, since the error is much more likely to be a parsing bug like this one.

• 8526: Avoid comparing sql.Types in dolt diff
  Fixes #8511
  Not all implementations of sql.Type are comparable. In particular, the enum type has a map field which makes the entire type incomparable.
  To avoid doing this comparison in the chooseMostFlexibleType function, we modify it to compare the underlying type tag instead. This PR also short-circuits computing a unified schema unless the schema has changed.
• 8514: Better view caching
  Binding a table name to a catalog symbol previously always loaded the schemas table from disk to first attempt binding a view. Now we cache dolt_schemas using its hash. If the table does not exist, no views are defined, and we short circuit attempting to bind a name to a view.

• 8522: libraries/doltcore/remotestorage: Improve connection reuse when fetching chunks from remote storage.
  Improves performance of fetches from DoltHub, sql-server, and doltlab.
  Improves some situations where routers and network access points do not respond well to clients which open a great number of connections to the same TCP endpoint, many of which live for a very short period of time.
  http.DefaultClient comes with a default MaxIdleConnsPerHost of 2. Fetching with a high number of concurrent downloads results in many connections not being reused efficiently because they cannot get back into the idle pool because it is so small. Here we increase the MaxIdleConnsPerHost to be large enough so that our active connections during a fetch will fit within it.
  Note: S3 limits a single HTTP connection to 100 requests, after which it is closed server-side. So currently dolt can still require a large number of new connections over the course of a pull, and the rate at which they are opened will depend on a number of factors including available throughput, round trip time resolving storage locations, etc. But this change will always be a big improvement over the old behavior.

• 2723: server/handle.go: doQuery cleanup of some error handling.

  GMS server handler is supposed to cancel running queries if the connection which issued them goes away. It does this by checking the connection state out-of-band anytime the query is running and canceling theh query if the connection goes away. The connection checking code is platform-specific and currently only works on Linux.
  In commit 538696b2c943ac7f3cacf1b67a3a5ff40ae64a00 I introduced a bug where the connection checking code tries to inspect the socket state of an already closed file descriptor. This change fixes the behavior so that the file descriptor is left open until the necessary socket state is extracted.

• 8462: dolt gc --full: Implement a flag for GC which will collect everything, including the old gen.
  Dolt GC is generational. By default, it moves all chunks reachable from commits into the old gen, and it leaves uncommitted data in the new gen. By default, it never revisits the chunks in the old gen. This means that if a branch with a lot of unique data exists during a GC, and then gets deleted, the storage taken up by that branch is never reclaimed by future garbage collection.
  This PR implements dolt gc --full, which performs a collection on the entire database, ignoring the generational aspects of previous collections and visiting the entire set of live data. At the end of a successful dolt gc --full, only data which was reachable at the start of the run and data which has been written during the run will be present in the database.
  Note: dolt gc --full visits every reachable chunk in the database and can be resource intensive. As a consequence of running dolt gc --full, any previously archived table files will be unarchived, and storage savings from the archiving will be lost. dolt gc --full involves copying chunks into new storage files, and fully materializing the new files before the old files are deleted; as a consequence, peak disk utilisation while running dolt gc --full can be up to 2x the existing size of the database.
