Baked-in build metadata for Hermes Agent.
|
|
|
|
Source installs report their git revision live via ``git rev-parse`` (see
|
|
``hermes_cli/dump.py`` and ``hermes_cli/banner.py``). That doesn't work inside
|
|
the published Docker image because ``.dockerignore`` excludes ``.git``, so
|
|
those callsites fall back to ``"(unknown)"`` / drop the banner suffix entirely.
|
|
|
|
To make ``hermes dump`` and the startup banner identify the exact commit the
|
|
image was built from, the Docker build writes the build-time ``$HERMES_GIT_SHA``
|
|
arg into ``<project_root>/.hermes_build_sha``. This module is the single
|
|
read-side helper consumed by both callsites — keeping the lookup in one place
|
|
so the file path and missing-file behaviour stay consistent.
|
|
|
|
Behaviour:
|
|
|
|
- Returns ``None`` when the file is absent. Source installs and dev images
|
|
built without the ``HERMES_GIT_SHA`` build-arg fall through to live-git
|
|
resolution in the caller, so non-Docker installs are unaffected.
|
|
- Returns ``None`` on any IO / decoding error. The build-sha is a nice-to-have
|
|
for support triage; nothing in the CLI is allowed to crash because of it.
|
|
- Truncates to ``short`` characters (default 8) to match the format used by
|
|
``git rev-parse --short=8`` throughout the codebase.
