The deep internal rebrand (user: "rename all compound symbols", "datastore_ good", "DB:: fine"):
- CamelCase symbols ClickHouse* -> Datastore* (358 distinct): mainEntryDatastoreServer,
DatastoreDictionarySource, DatastoreRevision, DatastoreVersion, etc. URL/repo lines skipped.
- snake targets + macros clickhouse_* -> datastore_* (850 occ): datastore_common_io,
datastore_add_executable, datastore_program_install, datastore_functions, etc. — uniform
across src + cmake + all CMakeLists, and the contrib wrappers that link/use them
(croaring, nuraft, corrosion, chdig, delta-kernel-rs, mongo-cxx).
- CLICKHOUSE_* macros -> DATASTORE_* (DATASTORE_OFFICIAL_BUILD, ENABLE_DATASTORE_*, etc.).
- project(ClickHouse) -> project(Datastore) so ${Datastore_SOURCE_DIR}/${Datastore_BINARY_DIR}
(45 refs) resolve.
Replace (not drop) -> collision-free. DB:: namespace kept (per direction). lowercase SQL
`clickhouse` dictionary-source keyword + clickhouse.com / github.com/ClickHouse URLs kept.
NEEDS BUILD VERIFICATION on spark/CI — uniform + inspected-consistent but uncompiled here.

# Probe-free replacement for CMake's `generate_export_header`.
|
|
#
|
|
# CMake's stock `generate_export_header` runs `try_compile` checks for hidden visibility
|
|
# and the `__attribute__((__deprecated__))` attribute. Build-time CMake checks are
|
|
# forbidden in Datastore (see `cmake/block_build_time_checks.cmake`); the compiler is
|
|
# fixed (Clang, see `cmake/tools.cmake`), and both features are statically known to be
|
|
# supported, so we emit the export header directly.
|
|
#
|
|
# Supported keyword arguments mirror the subset used by the contrib code:
|
|
# BASE_NAME base name for derived macro names
|
|
# EXPORT_MACRO_NAME override the export macro name
|
|
# NO_EXPORT_MACRO_NAME override the no-export macro name
|
|
# DEPRECATED_MACRO_NAME override the deprecated macro name
|
|
# STATIC_DEFINE macro that, when defined, makes the export macros expand to nothing
|
|
# EXPORT_FILE_NAME output path (relative paths resolve against the current binary dir)
|
|
# CUSTOM_CONTENT_FROM_VARIABLE name of a variable whose contents are appended to the file
|
|
# INCLUDE_GUARD_NAME override the include-guard macro name
