# Release preparation (0.1.0 development prototype)
|
|
|
|
|
|
|
|
|
|
Phase 9 makes source packaging, staged install/uninstall and repeatable builds
|
|
|
|
|
testable. It does not turn the prototype into a production-qualified DAW. The
|
|
|
|
|
version remains 0.1.0; no tag, external release or binary publication is created
|
|
|
|
|
by `make dist` or `make release`.
|
|
|
|
|
|
|
|
|
|
## Build and package
|
|
|
|
|
|
|
|
|
|
```sh
|
|
|
|
|
make release
|
|
|
|
|
make test-install
|
|
|
|
|
make test-recovery test-performance
|
|
|
|
|
make dist
|
|
|
|
|
make test-release
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
release builds optimized, warning-enabled C/C++ code, tests and the optional GUI
|
|
|
|
|
in BUILD_DIR/release with no debug paths, a source-prefix map, deterministic ar
|
|
|
|
|
metadata and FLTK include/define flags rather than distribution-specific LTO
|
|
|
|
|
flags. It retains assertions so the test harness actually runs. dist creates
|
|
|
|
|
BUILD_DIR/xtc-0.1.0.tar.gz using Python's standard library. It includes only Git
|
|
|
|
|
indexed regular files (working-tree contents, including staged new files), plus
|
|
|
|
|
a source manifest; stage intended files first and check `git diff --cached`.
|
|
|
|
|
Untracked files, ignored build output and .git are excluded. Exported archives
|
|
|
|
|
can reproduce themselves without Git using SOURCE_MANIFEST.json.
|
|
|
|
|
|
|
|
|
|
Archive order, permissions, ownership, gzip filename and timestamps are normalized.
|
|
|
|
|
SOURCE_DATE_EPOCH defaults to 0; set an unsigned 32-bit epoch explicitly if desired.
|
|
|
|
|
The archive does not claim to identify a commit: release from a clean checkout
|
|
|
|
|
and record its commit/hash externally. Do not treat a dirty-tree archive as an
|
|
|
|
|
attested release. No artifact is uploaded by these targets.
|
|
|
|
|
|
|
|
|
|
test-release unpacks the source into two different temporary paths, runs release
|
|
|
|
|
in each, compares libxtc.a/xtc-check/optional xtc SHA-256 values, and repacks each
|
|
|
|
|
export to compare archive bytes. This verifies reproducibility for the same host,
|
|
|
|
|
compiler, flags and dependency versions. It does not promise bit-identical output
|
|
|
|
|
across distributions, compilers or library updates. Compiler/debug/sanitizer
|
|
|
|
|
build directories are intentionally separate; changing toolchain/flags in place
|
|
|
|
|
requires a clean directory. Python release tests require version 3.12+.
|
|
|
|
|
|
|
|
|
|
## Qualification record
|
|
|
|
|
|
|
|
|
|
Run normal core/GUI and live software JACK tests, no-JACK builds and ASan/UBSan.
|
|
|
|
|
GUI leak tests retain the narrow fontconfig suppression; core tests do not.
|
|
|
|
|
TSan recorder/publication tests complement lifecycle tests. Native API tests
|
|
|
|
|
verify callback failures, cleanup and retirement; they cannot certify arbitrary
|
|
|
|
|
extensions. See BUILD.md and tests/integration/README.md for commands.
|
|
|
|
|
|
|
|
|
|
Record versions, archive hashes, installation/consumer checks and measured timing.
|
|
|
|
|
Use LICENSES.md for dependency/license review and PLUGIN_HOSTING.md for the
|
|
|
|
|
external-hosting decision. Review RECOVERY.md for migration and process-crash
|
|
|
|
|
semantics. Physical devices, power loss, sustained recording/performance, user
|
|
|
|
|
acceptance on other distributions and binary redistribution are still separate
|
|
|
|
|
qualification work. There is no DEB/RPM/AppImage, bundled runtime, autosave,
|
|
|
|
|
external plugin host or stable shared-library extension ABI in this release.

|
## Phase 20 local binary packaging and installed workflow
|
|
|
|
|
|
|
|
|
|
`make test-package` builds the release, stages installation only in a temporary
|
|
|
|
|
DESTDIR, writes a normalized Linux binary/development archive, checks its SHA-256
|
|
|
|
|
sidecar and per-file manifest, relocatable pkg-config paths and headless commands.
|
|
|
|
|
Same-host repeated packaging is byte-identical; dependency versions and toolchain
|
|
|
|
|
still determine binary compatibility. `make test-install` now repeats installation
|
|
|
|
|
to verify repair/upgrade of owned files while preserving an unrelated sentinel,
|
|
|
|
|
then compiles both C99 and C++17 installed consumers that create MIDI, save/reopen
|
|
|
|
|
and compare nonzero exact rendering. Removal remains exact and idempotent.
|
|
|
|
|
|
|
|
|
|
USER_MANUAL.md consolidates operation; KNOWN_LIMITATIONS.md lists qualification
|
|
|
|
|
gaps; MAINTENANCE.md defines the release checklist, regression and compatibility
|
|
|
|
|
policy. Build diagnostics make no server/plugin calls. There is no asynchronous
|
|
|
|
|
crash uploader or signal-handler cleanup: inspect OS core/debugger evidence on
|
|
|
|
|
the control side, preserving project/media recovery paths. No release is publicly
|
|
|
|
|
published by these commands, and human/device/listening checks remain pending.

## Phase 30 release workflow
|
|
|
|
|
|
|
|
|
|
Installation now shares one explicit file inventory with uninstallation. GNU-style
|
|
|
|
|
`exec_prefix`, `bindir`, `libdir`, `includedir`, `datarootdir`, `datadir`, `docdir`,
|
|
|
|
|
`pkgconfigdir` and the xtc-specific `licensedir`, `examplesdir`, `desktopdir` can be
|
|
|
|
|
overridden alongside `PREFIX`/`DESTDIR`. Paths must be absolute POSIX paths;
|
|
|
|
|
spaces are supported. Do not include DESTDIR in a directory variable: staging is
|
|
|
|
|
applied separately and never embedded in pkg-config metadata. Staging refuses
|
|
|
|
|
parent symlinks that escape DESTDIR. Use exactly the same variables for removal.
|
|
|
|
|
|
|
|
|
|
```sh
|
|
|
|
|
make BUILD_DIR=build/release-check all test gui
|
|
|
|
|
make BUILD_DIR=build/release-check test-install test-install-layout
|
|
|
|
|
make PREFIX=/usr DESTDIR=/tmp/xtc-stage libdir=/usr/lib64 install-gui
|
|
|
|
|
make PREFIX=/usr DESTDIR=/tmp/xtc-stage libdir=/usr/lib64 uninstall
|
|
|
|
|
make test-release test-package
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
Core install includes the static library, public headers, `xtc-check`, pkg-config
|
|
|
|
|
metadata, Markdown documentation, all checked-in performance reports, license and
|
|
|
|
|
`share/xtc/examples` (a media/plugin-free MIDI demo). GUI install adds the desktop
|
|
|
|
|
entry and `xtc`. No desktop MIME association is claimed. Package archives keep
|
|
|
|
|
their fixed `/usr` layout and relocatable pkg-config metadata; custom live layouts
|
|
|
|
|
are tested separately. Existing owned file symlinks are replaced, not followed;
|
|
|
|
|
installation is atomic per file, not a transaction over the entire prefix.
|
|
|
|
|
|
|
|
|
|
`make dist` now writes a `.sha256` sidecar as well as the normalized source archive.
|
|
|
|
|
Record that hash, the reviewed commit, version and build/dependency conditions
|
|
|
|
|
with release logs. `test-release` verifies the hash, builds/tests two fresh source
|
|
|
|
|
exports and compares artifacts and repacks. It validates exported tracked content,
|
|
|
|
|
including staged work; it does not attest that the caller's Git tree is clean.
|
|
|
|
|
For public release use a clean reviewed checkout and inspect `git status` first.
|
|
|
|
|
RELEASE_NOTES.md supplies upgrade guidance and remaining qualification limits.
