The vendored amalgamation (3.53.2, public domain) plus the curated bindings move from the distribution repo into the sx library: '#import "vendors/sqlite/sqlite.sx"' gives any sx program SQLite with no system dependency and no build flags — the bindings declare the C as a named #import c unit (pinned defines + -O2), compiled through the object cache and shadow-proof via unit-first resolution. examples/1624 pins the version and a typed round trip in-suite.

# vendors/sqlite — SQLite for sx programs
|
|
|
|
- Version: **3.53.2** (`SQLITE_VERSION` in `c/sqlite3.h`)
|
|
- Source: <https://sqlite.org/2026/sqlite-amalgamation-3530200.zip>
|
|
- Zip sha256: `8a310d0a16c7a90cacd4c884e70faa51c902afed2a89f63aaa0126ab83558a32`
|
|
- Files kept: `c/sqlite3.c`, `c/sqlite3.h` (the amalgamation; `shell.c`
|
|
and `sqlite3ext.h` dropped — no shell, no loadable extensions)
|
|
- License: public domain (<https://sqlite.org/copyright.html>)
|
|
|
|
`#import "vendors/sqlite/sqlite.sx"` gives any sx program SQLite with
|
|
no system dependency and no build flags. The bindings declare the
|
|
amalgamation as a named `#import c` unit carrying the pinned compile
|
|
options (`SQLITE_DQS=0`, `SQLITE_THREADSAFE=0`,
|
|
`SQLITE_DEFAULT_MEMSTATUS=0`, `SQLITE_OMIT_DEPRECATED`,
|
|
`SQLITE_OMIT_SHARED_CACHE`, `SQLITE_LIKE_DOESNT_MATCH_BLOBS`,
|
|
`SQLITE_ENABLE_COLUMN_METADATA`, `-O2`); sx compiles the unit through
|
|
its content-addressed object cache (`.sx-cache/`), so the 250k-line
|
|
source builds once per machine. `sx build` links the objects into the
|
|
binary; `sx run` loads them as a PRIORITY symbol-search target ahead
|
|
of the process images, so an OS libsqlite3 of a different version can
|
|
never shadow this copy. `examples/1624-vendor-sqlite-module.sx` pins
|
|
the version and a typed round trip in the sx suite.
|
|
|
|
## Bound surface
|
|
|
|
`sqlite.sx` maps the full practical C API (~100 functions): connection
|
|
lifecycle + open_v2 flags, errors (extended codes included), statements
|
|
with the complete bind/column families, parameter and column
|
|
introspection (built with `SQLITE_ENABLE_COLUMN_METADATA`), incremental
|
|
blob I/O, the online backup API, serialize/deserialize, and the library
|
|
utilities. Not bound, by design: callback-taking APIs (hooks, UDFs,
|
|
collations, authorizers — they need C→sx callbacks), the
|
|
`sqlite3_value_*` family (UDF-coupled), varargs configuration, UTF-16
|
|
variants, and subsystems this build omits (mutex/VFS under
|
|
`SQLITE_THREADSAFE=0`, sessions/snapshots/vtabs, deprecated API).
|
|
|
|
To upgrade: replace `c/sqlite3.c`/`c/sqlite3.h` with a newer
|
|
amalgamation, update this file and the version pins in consuming test
|
|
suites, and rebuild (the object cache keys on the source bytes, so the
|
|
new amalgamation recompiles automatically).
