   6 Steps to take before starting on the first pretest in any release sequence:
   7
   8 1.  Decide on versions of automake and autoconf, and ensure you will
   9     have them available for the duration of the release process.
  10
  11 2.  Consider increasing the value of the variable
  12     `customize-changed-options-previous-release' in cus-edit.el to
  13     refer to a newer version of Emacs.  (This is probably needed only
  14     when preparing the first pretest for a major Emacs release.)
  15     Commit cus-edit.el if changed.
  16
  17
  18 General steps (for each step, check for possible errors):
  19
  20 1.  `bzr update' (for a bound branch), or `bzr pull'.
  21      bzr status   # check for locally modified files
  22
  23 2.  Bootstrap to make 100% sure all elc files are up-to-date, and to
  24     make sure that the later tagged version will bootstrap, should it be
  25     necessary to check it out.
  26
  27 3.  Regenerate the etc/AUTHORS file:
  28       M-: (require 'authors) RET
  29       M-x authors RET
  30
  31     There is almost guaranteed to be an "*Authors Errors*" buffer with
  32     problems caused by certain bad ChangeLog entries.  You can ignore
  33     the very old ones (eg lisp/erc has a lot).  If there are errors
  34     related to new entries (especially entries that are new since the
  35     last pretest), see if you can fix them.  If there was a ChangeLog
  36     typo, fix it.  If a file was deleted or renamed, consider adding
  37     an appropriate entry to authors-ignored-files, authors-valid-file-names,
  38     or authors-renamed-files-alist.
  39
  40     If necessary, repeat M-x authors after making those changes.
  41     Save the "*Authors*" buffer as etc/AUTHORS.
  42     Check the diff looks reasonable.  Maybe add entries to
  43     authors-ambiguous-files or authors-aliases, and repeat.
  44     Commit any fixes to ChangeLogs or authors.el.
  45
  46 4.  Set the version number (M-x load-file RET admin/admin.el RET, then
  47     M-x set-version RET).  For a release, add released ChangeLog
  48     entries (M-x add-release-logs RET).
  49
  50     For a pretest, start at version .90.  After .99, use .990 (so that
  51     it sorts).
  52
  53 5.   autoreconf -i -I m4 --force
  54      make bootstrap
  55
  56 6.  Copy lisp/loaddefs.el to lisp/ldefs-boot.el.
  57
  58     Commit etc/AUTHORS, lisp/ldefs-boot.el, and the files changed
  59     by M-x set-version.
  60     For a release, also commit the ChangeLog files in all directories.
  61
  62 7.  ./make-dist --snapshot --no-compress
  63
  64     Check the contents of the new tar with
  65     admin/diff-tar-files against an older tar file.  Some old pretest
  66     tarballs may be found at <ftp://alpha.gnu.org/gnu/emacs/pretest>;
  67     old release tarballs are at <ftp://ftp.gnu.org/pub/gnu/emacs/>.
  68
  69     If this is the first pretest of a major release, just comparing
  70     with the previous release may overlook many new files.  You can try
  71     something like `find . | sort' in a clean bzr tree, and compare the
  72     results against the new tar contents.
  73
  74 8.   tar -xf emacs-NEW.tar; cd emacs-NEW
  75      ./configure --prefix=/tmp/emacs && make && make install
  76     Use `script' or M-x compile to save the compilation log in
  77     compile-NEW.log and compare it against an old one.  The easiest way
  78     to do that is to visit the old log in Emacs, change the version
  79     number of the old Emacs to __, do the same with the new log and do
  80     M-x ediff.  Especially check that Info files aren't built.
  81
  82 9.  cd EMACS_ROOT_DIR && bzr tag TAG
  83     TAG is emacs-XX.Y.ZZ for a pretest, emacs-XX.Y for a release.
  84
  85     Shortly before the release, cut the version branch also, and open
  86     a Savannah support request asking for commits to the new branch to
  87     be sent to the emacs-diffs mailing list (by default, the list
  88     normally only gets commits to the trunk).
  89
  90 10. Decide what compression schemes to offer.
  91     For a release, at least gz and xz:
  92       gzip --best -c emacs-NEW.tar > emacs-NEW.tar.gz
  93       xz -c emacs-NEW.tar > emacs-NEW.tar.xz
  94
  95     Now you should upload the files to the GNU ftp server.  In order to
  96     do that, you must be registered as an Emacs maintainer and have your
  97     GPG key acknowledged by the ftp people.  For instructions, see
  98     http://www.gnu.org/prep/maintain/html_node/Automated-Upload-Registration.html
  99     The simplest method is to use the gnulib <http://www.gnu.org/s/gnulib/>
 100     script "build-aux/gnupload" to upload each FILE, like this:
 101
 102     For a pretest:
 103      gnupload [--user your@gpg.key.email] --to alpha.gnu.org:emacs/pretest \
 104        FILE.gz FILE.xz ...
 105
 106     For a release:
 107      gnupload [--user your@gpg.key.email] --to ftp.gnu.org:emacs \
 108        FILE.gz FILE.xz ...
 109
 110     You only need the --user part if you have multiple GPG keys and do
 111     not want to use the default.
 112     Obviously, if you do not have a fast uplink, be prepared for the
 113     upload to take a while.
 114
 115
 116     If you prefer to do it yourself rather than use gnupload:
 117
 118     For each FILE, create a detached GPG binary signature and a
 119     clearsigned directive file like this:
 120
 121      gpg -b FILE
 122      echo directory: emacs/pretest > FILE.directive      (for a pretest)
 123      echo directory: emacs > FILE.directive              (for a release)
 124      gpg --clearsign FILE.directive
 125     Upload by anonymous ftp to ftp://ftp-upload.gnu.org/ the files FILE,
 126     FILE.sig, FILE.directive.asc.
 127     For a release, place the files in the /incoming/ftp directory.
 128     For a pretest, place the files in /incoming/alpha instead, so that
 129     they appear on ftp://alpha.gnu.org/.
 130
 131 11. After five minutes, verify that the files are visible at
 132     ftp://alpha.gnu.org/gnu/emacs/pretest/ for a pretest, or
 133     ftp://ftp.gnu.org/gnu/emacs/ for a release.
 134
 135     Download them and check the signatures.  Check they build.
 136
 137 12. For a pretest, announce it on emacs-devel and info-gnu-emacs@gnu.org.
 138     For a release, also announce it on info-gnu@gnu.org.  (Probably
 139     bcc the info- addresses to make it less likely that people will
 140     followup on those lists.)
 141
 142 13. For a release, update the Emacs homepage in the web repository.
 143     Also add the new NEWS file as NEWS.xx.y.
 144     Maybe regenerate the html manuals, update the FAQ, etc, etc.
