Pure rename applied on top of upstream tag v2.6.2 (8d2415d6), not HEAD.
The fork was cut at 737145d = v2.6.2-57, which still declared version 2.6.2
in version.h; renaming there would have shipped 57 unreleased commits wearing
a 2.6.2 label. Reset to the tag first so this commit changes names only.
clickhouse/ -> datastore/ (public include root)
namespace clickhouse -> namespace datastore
CLICKHOUSE_CPP_VERSION -> DATASTORE_CPP_VERSION
clickhouse-cpp-lib/-ut -> datastore-cpp-lib/-ut (CMake, Bazel)
CH_MAP_BOOL_TO_UINT8 -> DS_MAP_BOOL_TO_UINT8
CLICKHOUSE_* -> DATASTORE_* (test env vars)
doc links -> docs.hanzo.ai/datastore
This client speaks the NATIVE binary protocol only - there is no HTTP path
and no X-ClickHouse-* header anywhere in it, so the header rename that the
HTTP clients required does not apply and nothing here was broken.
The one string that reaches the wire is CLIENT_NAME, sent by both SendHello
and SendQuery's ClientInfo from a single macro, and it lands in
system.query_log.client_name. Both sites still read the one macro, so they
stay consistent and the server's Hello/Query consistency check is satisfied.
Old rows keep the old name; that is a reporting discontinuity, not a
migration, since nothing keys on it.
CI is repointed at our own server: ghcr.io/hanzoai/datastore:26.2.3.2, the
image production runs. Its entrypoint honours DATASTORE_SKIP_USER_SETUP, not
the CLICKHOUSE_ spelling the compose file used, and its config lives in
/etc/hanzo-datastore-server. ci/docker-compose/config.xml is now layered in
as a config.d drop-in so the image keeps its own white-labelling. That file
and users.xml deliberately keep a <clickhouse> root: it must match the roots
of the drop-ins the image ships, and a mismatch fails silently - the server
logs "Merging bypassed" and starts with every drop-in discarded.
The remote-TLS suites used to default to the third-party host
play.clickhouse.com. They now read DATASTORE_SECURE*_HOST and skip when it is
unset rather than point at a host we do not run.
Dropped as upstream infrastructure with no meaning here: AI_POLICY.md
(upstream's policy about their codebase), .travis.yml (dead CI referencing a
third-party apt repo), cross-repo-bug-relay.yml (relays our issues into an
upstream triage repo). LICENSE keeps its copyright notice, as Apache-2.0
requires.
Verified: cmake configure + 115-target build clean; the full suite is green
against ghcr.io/hanzoai/datastore:26.2.3.2 (894 passed, 0 failed); the
pristine v2.6.2 build run against that same server passes the identical set,
and both logged the same 3914 queries under their respective client names.
