================= Release checklist ================= Checklist for ordinary releases =============================== * Git branch naming note - ``vN.N.N-release-prep``: use this naming for bumping version number, etc. Merge to master before tagging release. - ``vN.N.N-release-post``: use this naming for bumping version number after release, checklist fixes after release, etc. * Git maintenance - ensure git commits are up-to-date - ensure branches are merged, unused branches deleted (also remotely) - ensure branches are rebased where applicable - git fsck --full - git gc --aggressive * Ditz maintenance - Ensure Ditz issues for the new release are all closed * Finalize DUK_VERSION - Change previous development version (with patch level 99) to release version - Verify by running Duktape cmdline and evaluating ``Duktape.version`` * Check dist-files/README.rst * Ensure LICENSE.txt is up-to-date - Check year range * Ensure RELEASES.rst is up-to-date (must be done before candidate tar.xz build because dist package contains RELEASES.rst) - New release is in place - Release log entries match ditz issues - Release date is in place * Compilation tests: - Clean compile for command line tool with (a) no options and (b) common debug options (DUK_OPT_DEBUG, DUK_OPT_DPRINT, DUK_OPT_SELF_TESTS, DUK_OPT_ASSERTIONS) - Compile both from ``src`` and ``src-separate``. - Run ``mandel.js`` to test the the command line tool works. - Platform / compiler combinations (incomplete, should be automated): + Linux x86-64 gcc + Linux x86-64 gcc + -m32 + Linux x86-64 clang + Linux x86-64 clang + -m32 + FreeBSD clang + FreeBSD clang + -m32 + Windows MinGW + Windows MinGW-w64 + Windows MSVC (cl) x86 + Windows MSVC (cl) x64 + Windows Cygwin 32-bit + Windows Cygwin 64-bit + Linux MIPS gcc + Linux ARMEL gcc (little endian) + Linux gcc on some mixed endian ARM platform + Linux SH4 gcc * Compile command line tool as a Windows DLL, checks Windows symbol visibility macros:: > cd dist > cl /O2 /DDUK_OPT_DLL_BUILD /Isrc /LD src\duktape.c > cl /O2 /DDUK_OPT_DLL_BUILD /Isrc examples\cmdline\duk_cmdline.c duktape.lib > duk_cmdline.exe * Ecmascript testcases - **FIXME: semiautomate test running for various configurations** - On x86-64 (exercise 16-byte duk_tval): - make qecmatest # quick test - VALGRIND_WRAP=1 make qecmatest # valgrind test - On x86-32 (exercise 8-byte duk_tval) - make qecmatest # quick test - Run testcases on all endianness targets - Run with assertions enabled at least on x86-64 * Run testcases with torture options - DUK_OPT_GC_TORTURE - DUK_OPT_SHUFFLE_TORTURE * Memory usage testing - Leaks are mostly detected by Valgrind, but bugs in valstack or object resize algorithms (or similar) can lead to unbounded or suboptimal memory usage - XXX: establish some baseline test * Performance testing - Check for unexpected performance regressions by compiling previous release and candidate release with ``-O2`` and running "make perftest" for them. * API testcases - On x86-64: - make apitest * Compile option matrix test - Run 1000 iterations of ``util/matrix_compile.py`` which compiles and runs random combinations of feature options and compilers (gcc, g++, clang) on x86, x64, and x32 * Regfuzz - On x86-64, with DUK_OPT_ASSERTIONS - make regfuzztest * test262 - on x86-64 - make test262test - Run with assertions enabled at least on x86-64 * emscripten (run emscripten-generated code with Duktape) - on x86-64 - make emscriptentest * emscripten (compile Duktape with emscripten, run with Node) - on x86-64 - make emscriptenduktest * JS-Interpreter - on x86-64 - make jsinterpretertest * lua.js - on x86-64 - make luajstest * Release notes (``doc/release-notes-*.rst``) - Write new release notes for release; needs known issues output from at least API, Ecmascript, and test262 test runs - Ensure instructions for upgrading from last release are correct * Git release and tag - Tagging should be done before creating the candidate tar files so that "git describe" output will have a nice tag name. - This will be a preliminary tag which can be moved if necessary. Don't push it to the public repo until the tag is certain not to move anymore. - There can be commits to the repo after tagging but nothing that will affect "make dist" output. - Make sure the tag is in the master commit chain, so that git describe will provide a useful output for dist packages built after the release - ``git tag -l -n1`` to list current tags - ``git tag -s -m "" vN.N.N`` to set tag - ``git tag -f -s -m "" vN.N.N`` to forcibly reset tag if it needs to be moved * If release is a stable major/minor release (e.g. 1.1.0), create a maintenance branch ``vN.N-maintenance`` off the release tag. * Build candidate tar.xz files - These should remain the same after this point so that their hash values are known. - Check git describe output from dist ``README.rst``, ``src/duktape.h``, and ``src/duktape.c``. It should show the release tag. * Check source dist contents - Check file list - Grep for FIXME and XXX - Trivial compile test for combined source - Trivial compile test for separate sources (important because it's easy to forget to add files in make_dist.sh) - Test Makefile.dukdebug + debugger/duk_debug.js to ensure all files are included (easy to forget e.g. YAML metadata files) * Store binaries to duktape-releases repo - Add the tar.xz to the master branch - Create an independent branched named ``unpacked-vN.N.N`` with unpacked tar.xz contents + http://stackoverflow.com/questions/15034390/how-to-create-a-new-and-empty-root-branch + http://stackoverflow.com/questions/9034540/how-to-create-a-git-branch-that-is-independent-of-the-master-branch - Tag the final branch with ``vN.N.N``, push the tag, and delete the branch. The branch is not pushed to the server. - The concrete commands are packaged into ``add-unpacked.sh`` in duktape-releases repo. * Update website downloads page - Release date - Link - Date - "latest" class - Release notes (layout and contents) for release * Build website - Readthrough - Test that the Duktape REPL (Dukweb) works - Check duk command line version number in Guide "Getting started" - Diff website HTML against current website * Ditz release - ``ditz release vN.N`` - git add and commit ditz issues * Upload website and test * Final Git stuff - Ensure ``master`` is pushed and unnecessary branches are cleaned up - Push the release tag - Push the maintenance branch if created * Make GitHub release - Release description should match tag description but be capitalized - Attach the end user distributable to the GitHub release * Bump Duktape version for next release and testing - Set patch level to 99, e.g. after 0.10.0 stable release, set DUK_VERSION from 1000 to 1099. This ensures that any forks off the trunk will have a version number easy to distinguish as an unofficial release. - ``src/duk_api_public.h.in`` * Update ``DITZ_RELEASE`` in ``Makefile`` - It should point to the next expected release so that ``make issuecount`` and ``make issues`` provide useful output Checklist for maintenance releases ================================== * Make fixes to master and cherry pick fixes to maintenance branch (either directly or through a fix branch). Test fixes in maintenance branch too. * Update release notes and website in master. **Don't** update these in the maintenance branch. * Bump DUK_VERSION in maintenance branch. * Review diff between previous release and new patch release. * Tag release, description "maintenance release" should be good enough for most patch releases. * Build release, push it to ``duktape-releases`` in binary and unpacked form. * Build website from master. Deploy only ``download.html``. This is rather hacky: we need the release notes so the build must be made from master, but master may also contain website changes for the next release.
