Add --access-log <path> (env ZDDC_ACCESS_LOG). When set, every access-
log record is written as a JSON line to the configured file in
addition to the existing slog.Default() stderr output. Empty (default)
keeps the prior behavior — stderr only.
Rotation via gopkg.in/natefinch/lumberjack.v2:
100 MB per file, 10 backups, 90-day max age, gzip rotated files.
Operator usage (e.g. behind a Caddy/quadlet stack):
zddc-server --access-log /srv/.zddc.d/logs/access.log ...
Architecture:
AccessLogMiddleware now takes an optional *slog.Logger. main.go wires
it via setupAccessAuditLog() which builds a slog.JSONHandler over a
lumberjack rotator. Stderr emission stays via slog.Default(); the
audit logger gets the same fields in line-delimited JSON, the format
every standard log shipper (Vector, Loki, fluentbit, journalbeat)
parses natively.
Tests cover the audit logger receiving the same email/path/status
fields as the stderr stream.
Add github.com/klauspost/compress/gzhttp wrapper around the request
handler. With MinSize(1024), responses ≥ 1 KB get gzip-encoded when
the client advertises Accept-Encoding: gzip; smaller bodies + 304
Not Modified pass through unchanged.
The wrapper auto-appends Vary: Accept-Encoding (compatible with the
existing Vary: Accept on directory.go's content-negotiated path).
Live-tested against zddc-server -root /tmp/empty:
GET / w/ Accept-Encoding: gzip → 20.9 KB compressed (was 80.9 KB
uncompressed). 74% reduction.
Decompresses cleanly back to the original bytes.
Helps every code path that bypasses Caddy: devshell pods, local dev
binaries, tests, anywhere zddc-server is hit directly. Production
behind Caddy already had compression at the proxy layer; this just
makes the Go server self-sufficient.
Tests in cmd/zddc-server/main_test.go cover:
- large body + Accept-Encoding → compressed + Vary header
- small body → not compressed (under MinSize)
- no Accept-Encoding header → plain bytes
ZDDC — Zero Day Document Control. A file-naming convention plus five
single-file HTML tools (archive, transmittal, classifier, mdedit,
landing) and an optional Go HTTP server (zddc-server) with ACL and a
virtual archive index. Self-contained, offline-capable, dependency-free.
See README.md for an overview, AGENTS.md and ARCHITECTURE.md for the
build/release/architecture detail, bootstrap/README.md for the
two-level deployment install pattern, and zddc/README.md for the
HTTP server.
