Release Notes
Windows is now a supported platform, and hybrid search returns results in ranked order rather
than insertion order. No migration; lbug stays pinned at 0.18.1.
Added
- Windows (x64) support.
lcg-service builds and runs on Windows, using a named-pipe IPC
transport in place of the Unix domain socket. Every pipe instance carries a protected DACL
granting only the service's own user and SYSTEM (the default pipe DACL grants Everyone read),
refuses remote clients, and claims its name with FILE_FLAG_FIRST_PIPE_INSTANCE. The service
writes the pipe name to .lcg/service.endpoint so clients in other languages can discover it,
and Windows console-control events drive clean shutdown. (#581, #582)
- A published Windows artifact,
x86_64-pc-windows-msvc, installable via a new PowerShell
installer or the .zip. OpenSSL is linked statically into the executable — a deliberate
Windows-only exception to ADR-0550's dynamic posture, since an archive cannot carry DLLs for one
target and no Windows package manager would patch a DLL we shipped. The two OpenSSL DLLs that
lbug's own extensions import are bundled beside them and resolved at load time. Consequence: an
OpenSSL CVE fix requires a new lcg release on Windows, where macOS and Linux pick it up from the
system. See ADR-0581. (#585, #586)
Fixed
find_entities and find_relationships returned results in insertion order, not ranked
order. Both fetch rows with a WHERE uuid IN lookup carrying no ORDER BY, so the RRF-fused
ranking computed immediately beforehand was discarded — every hybrid search returned the correct
top-k set in an arbitrary order. Rows now follow the fused ranking. (#584)- Bundled lbug extensions were not found when lcg was launched through a symlink. On macOS and
Windows current_exe() reports the path the process was launched as, so a stable symlink into a
versioned install resolved the bundle against the link's directory, missed the .lbdb tree beside
the real binary, and silently fell back to downloading from the CDN — voiding 0.14.2's offline
guarantee with no error. The executable path is now canonicalized. (#583)
Windows notes
- Requires the Microsoft Visual C++ Redistributable (x64, 2015–2022). It is not bundled and is
present on most machines; without it the executable fails to start with a loader error.
- Verified on Windows 11 x64. Windows 10 and Windows ARM are untested; no Windows ARM build is
published.
- Downstream clients must read
.lcg/service.endpoint to locate the pipe. orac does; the
Liminis app and liminis-framework do not yet.
lbug stays at 0.18.1. The published Windows vector and fts extensions for the entire
lbug 0.20.x line crash the process — a regression from 0.19.0, reproducible with LadybugDB's own
CLI and unrelated to lcg. The lbug upgrade is deferred until that is fixed upstream, so all four
platforms can move together. See docs/releases/0.14.3.md.
