Memory Pool System Release Build Procedure ========================================== :author: Richard Brooksby :organization: Ravenbrook Limited :date: 2002-06-17 :revision: $Id: //info.ravenbrook.com/project/mps/version/1.112/procedure/release-build.rst#1 $ :confidentiality: public :copyright: See `C. Copyright and License`_ 1. Introduction --------------- This is the procedure for building a generic release of the Memory Pool System (an “MPS Kit”) from the version sources. The intended readership of this document is Ravenbrook development staff. (If you are a user of the MPS, and want to build object code from an MPS Kit, please see the ``readme.txt`` file in the kit.) This document is not confidential. All relative paths are relative to ``//info.ravenbrook.com/project/mps/``. 2. Creating a version branch ---------------------------- #. Make sure you have a version branch from which to make the release. If not, follow the `version creation procedure `_ first. .. _version-create: version-create 3. Setting up for release ------------------------- #. Choose a *RELEASE* name of the form *VERSION.N* (for example, 1.111.0), where *VERSION* is the number of the version you’re releasing, and *N* is the first unused release number (starting at zero). Look in the index of releases (``release/index.html``) for existing release numbers for your version:: VERSION=A.BBB RELEASE=$VERSION.N #. Ensure that ``version/$VERSION/readme.txt`` contains an up-to-date description of the release you intend to build and the correct release name. #. Ensure that ``version/$VERSION/manual/source/release.txt`` contains a section with an up-to-date description of significant user-visible changes since the previous release. #. In ``version/$VERSION/code/version.c``, set ``MPS_RELEASE`` to the correct value (see the rules in the comments), and check strings that contain copyright dates, etc. #. In ``configure.ac`` edit the second argument of ``AC_INIT`` to be "``release $RELEASE``\ ", then open ``configure`` for edit and run ``autoreconf -vif`` to bring the configure script up to date. #. Submit ``readme.txt``, ``manual/source/release.txt``, ``version.c``, ``configure.ac``, ``configure``, and other changed files to Perforce before you continue. #. Determine the *CHANGELEVEL* at which you’re going to make the release. This will usually be the latest submitted changelevel on the version branch; to get it, use ``p4 changes -m 1``:: CHANGELEVEL=$(p4 changes -m 1 version/$VERSION/... | cut -d' ' -f2) 4. Pre-release testing ---------------------- #. Sync the version sources to precisely the *CHANGELEVEL* you determined above, with no extraneous files, by using the following procedure:: p4 opened version/$VERSION/... # should output nothing p4 revert version/$VERSION/... rm -rf version/$VERSION p4 sync -f version/$VERSION/...@$CHANGELEVEL Note that the ``revert`` and ``sync -f`` are necessary, otherwise opened files may be left in place, or writeable-on-client files may be omitted; see [RHSK_2008-10-16]_. #. Run the test suite:: (cd version/$VERSION && ./configure && make test) Check that the test suite passes. #. Repeat for all supported platforms. On Windows the sequence of commands to run the test suite are:: cd version\$VERSION\code nmake /f w3i6mv.nmk testrun On other platforms they are as shown above. 5. MPS Kit Tarball and Zip file ------------------------------- .. note:: If you are creating a customer-specific variant then vary the release name according to the variant, for example, ``mps-cet-1.110.0.zip`` On a Unix box: #. Create a fresh Perforce client workspace containing the following:: LineEnd: local View: //info.ravenbrook.com/project/mps/version/VERSION/... //CLIENT/mps-kit-RELEASE/... //info.ravenbrook.com/project/mps/release/RELEASE/... //CLIENT/release/RELEASE/... #. Ensure the Perforce client workspace is set for Unix (LF) line endings. #. Sync the version sources to *CHANGELEVEL* by repeating the procedure from step 4.1:: rm -rf mps-kit-RELEASE p4 sync -f @CHANGELEVEL #. Create a tarball containing the MPS sources, and open it for add:: mkdir -p release/RELEASE tar czf release/RELEASE/mps-kit-RELEASE.tar.gz mps-kit-RELEASE p4 add release/RELEASE/mps-kit-RELEASE.tar.gz #. Ensure the Perforce client workspace is set for Windows (CRLF) line endings. #. Sync the version sources again. #. Create a zip file containing the MPS sources, and open it for add:: mkdir -p release/RELEASE zip -r release/RELEASE/mps-kit-RELEASE.zip mps-kit-RELEASE p4 add release/RELEASE/mps-kit-RELEASE.zip #. Revert any changes to your Perforce client line endings. (You probably want them set to local.) #. Submit the release files to Perforce with the comment "MPS: adding the MPS Kit tarball and zip file for release RELEASE." 6. Registering the release -------------------------- #. Edit the index of releases (``release/index.html``) and add the release to the table, in a manner consistent with previous releases. #. Edit the index of versions (``version/index.html``) and add the release to the list of releases for *VERSION*, in a manner consistent with previous releases. #. Submit these changes with the comment “MPS: registered release *RELEASE*.” #. Edit the main MPS Project index page (``index.html``), to refer to the new release: - update links to “the latest release” or “download” (important); - consider updating the “project status” section. #. Visit the `project updater `__, select “mps” from the dropdown, and hit “Find releases”. #. Inform the project manager and staff by e-mail to mps-staff@ravenbrook.com. Consider announcing the new release by e-mail to mps-discussion@ravenbrook.com. A. References ------------- ..

Document History ------------------- ========== ===== ========================================================== 2002-06-17 RB_ Created based on P4DTI procedure. 2002-06-19 NB_ Fixed up based on experience of release 1.100.0. 2004-03-03 RB_ Fixed the way we determine the release changelevel to avoid possible pending changelists. 2005-10-06 RHSK_ Clarify this procedure is for general MPS Kit releases; correct ``cp -r`` to ``-R``. Add: check ``version.c``. 2006-01-19 RHSK_ Correct readership statement, and direct MPS users to the mps-kit readme. 2006-02-16 RHSK_ Use Info-ZIP (free) for Windows archives, not WinZip. 2007-07-05 RHSK_ Releasename now also in ``w3build.bat``. 2008-01-07 RHSK_ Release changelevel was in ``issue.cgi``, now in ``data.py``. 2010‑10‑06 GDR_ Use the project updater to register new releases. 2012‑09‑13 RB_ Don’t copy the ``readme.txt`` to the release directory, since it no longer has that dual role; make the ZIP file on a Unix box with the zip utility, since compatibility has improved. 2013-03-08 GDR_ Add testing step. 2012‑09‑24 RB_ Make sure ZIP files contain files with Windows line endings. Use a fresh Perforce client to avoid any possibility of a clash with working files. Different archive name for custom variants. 2013-03-20 GDR_ Ensure that manual HTML is up to date before making a release. ========== ===== ========================================================== .. _RB: mailto:rb@ravenbrook.com .. _NB: mailto:nb@ravenbrook.com .. _RHSK: mailto:rhsk@ravenbrook.com .. _GDR: mailto:gdr@ravenbrook.com C.
