Notes on putting together the pretest and yearly release --karl.

Check if pretest mirrors need renewing, talk to mirror admins if so:
 http://tug.org/texlive/mirmon/
 /home/httpd/html/texlive/mirmon/tlpretest-mirrors.txt

Coordinate schedule with:
 engine people, LaTeX people, GUST font people
 general lists

To stop updating of certain packages before the general freeze:
 tlpkg/dev/tlnet-disabled-packages.txt

On the day of the last tlnet update,
 Set opt_frozen in 00texlive.installation.tlpsrc.
 Freeze should happen at that night's rebuild.


Then, the next day, start building tlpretest:

0. Reset opt_frozen to 0 in 00texlive.installation.tlpsrc.

1a. Set up tlpretest:
cd /home/ftp/texlive/tlnet
tar cf - [a-u]* | (cd ../tlpretest && tar xf -)  # do not copy README
Update pretest.html, notably including major changes this year;
diff new and old bindirs to see if there are interesting new programs.
Update /home/ftp/texlive/tlpretest/README.

1b. Preserve final tlnet of current release:
cp -ar ../tlnet /home/ftp/historic/systems/texlive/YYYY/tlnet-final

2. Then switch to pretest in cron.tl:
critical=--critical	# push tlcritical
pretest=--pretest	# update tlpretest, not tlnet (if not frozen)
net_frozen=false 	# update tlnet|tlpretest (per $pretest)

(tlcritical will remain getting updated daily, even though it doesn't
 work with tlnet any more.  That's ok.)

3. The next nightly build will update tlpretest, or run
force_rebuild=true cron.tl

4. Basic updates for release year (to start pretest):
Master/.mkisofsrc
Master/release-texlive.txt
Master/texmf-dist/web2c/texmf.cnf
Master/texmf-dist/web2c/texmfcnf.lua
Master/tlpkg/TeXLive/TLConfig.pm
Master/tlpkg/bin/tl-update-tlnet

5. When closer to release:
in cron.tl, set images_frozen=false.
in tl-update-images, ensure V= the new YYYY and target=/.../test
update /home/ftp/texlive/Images/test/README
after successful image build, email tldistro@tug.org for info/review.


Really test during pretest (really!):
  .fmt's sharable across endian-different platforms (including luatex).
  interactive mf '\drawdot (50,50); showit;'

When finalizing sources (can be even before tlnet freeze for pretest)
  version numbers and years and copyright years in:
  top level version.ac
  dvipdfmx: configure.ac ChangeLog
  dvips:    configure.ac ChangeLog NEWS dvips.c dvips.h afm2tfm.c dvips.texi
  kpathsea: version.ac ChangeLog NEWS kpsewhich.c doc/kpathsea.texi texmf.cnf
  ptexenc:  version.ac ChangeLog
  web2c:    NEWS doc/web2c.texi luatexdir/lua/luainit.w 
  install-tl, tlmgr.pl (copyright only)
  run ~karl/bin/tlversions to see+compare engine/etc. versions

After tlnet freeze:
  in Master/tlpkg, update bundled Windows programs as needed:
    dviout texworks tlgs tlperl tlpsv

When binary set and docs are stable enough:
  peb + laurens + khaled: no commits.
  Compare Build/source/inst/texmf to texmf.
  tl-update-txi
  tl-update-man # and run make in texmf/doc/man
  # and check /tmp/so.rules against man1/Makefile

Just before total freeze:
  option adjustrepo in tl-update-tlnet, else install-tl-unx won't go to ctan?
  put date into NEWS and ChangeLog files.
  update Master/source:
    w32tex-src texlive*source mactexdoc install-tl-unx.tar.gz 

To do total freeze:
  in cron.tl, set *_frozen=true.
  probably also just disable the cron entry.


Making the big release:

- Live unmount of last year's:
umount /home/ftp/texlive/Contents/live

hx=/home/ftp/historic/systems/texlive
prev=2012
this=2013
mkdir $hx/$this

cd /home/ftp/texlive/Images
cp README.html $hx/$prev/
mv *.iso* $hx/$prev/
mv test/*.iso* .
mv test/texlive*.tar.xz* $hx/$this/  # tar version only from historic
update README and test/README

cd /home/ftp/texlive/tlnet
mkdir $hx/$prev/tlnet
cd /home/ftp/texlive/tlnet
diff -qr . $hx/$prev/tlnet-final # should already be there from before, so:
rm -rf [a-z]*
mv ../tlpretest/[a-z]* .
update README and ../tlpretest/README

cd /home/httpd/html/texlive
mkdir $hx/$prev/web
cp *.html !$  # remove tugstyle.css ref from bugs.html


- tug.org stuff:
do full install to default location.
rm /usr/local/texlive-rel; ln -s texlive/$this /usr/local/texlive-rel
create source/ subdir, cp texlive-*-source.tar.xz and w32tex-src.tar.xz
change /etc/fstab, mount /home/ftp/texlive/Contents/live.
update ~www/texlive web pages (search for $prev):
  acquire* - general
  bugs.html - general
  doc.html - platform list, translation list
  quickinstall.html - paths
  w32client.html - new w32client*.zip needed (siep)
update historic/systems with final proTeXt and MacTeX, when ready.
  https://bscw.fernuni-hagen.de
  ftp://ftp.fernuni-hagen.de/pub/windows/win32/ProTeXt/
update TUG member area with CTAN snapshot, when ready.

- announcements:
Dick Koch @ updating MacTeX.
CTAN @ re-enabling tlnet mirroring.
Martin @ torrents.
Nikola @ FreeBSD binaries.
pretest mirror admins @ done till next year (~www/texlive/mirmon/tl*.txt).

- make tag + branch:
svn copy -r 26940 -m'texlive-2012.0 tag based on r26940' \
  svn://tug.org/texlive/trunk svn://tug.org/texlive/tags/texlive-2012.0
svn copy -r 26940 -m'branch2012 branch based on r26940' \
  svn://tug.org/texlive/trunk svn://tug.org/texlive/branches/branch2012

  It's the same command, just different destinations.
  http://svnbook.red-bean.com/en/1.5/svn-book.html#svn.branchmerge

  Do both a branch and a tag so that it's possible to easily compare the
  current state of the branch with its starting point (the tag).

  To check out the branch, for critical source fixes for the sake of
  during-the-year rebuilds or for the distros, if they request it:
cd /home/texlive
rm -rf branch # when starting a new year on tug
mkdir branch; cd branch
svn co file:///home/svn/texlive/branches/branch2012/Build/source . >&out

- update ~karl/bin/cron.tl, and reenable when feel ready.

pretest=
net_frozen=false
