Notes on putting together the pretest and yearly release --karl.
See ./packages.txt for info on regular updates, adding/removing platforms, etc.

Coordinate schedule with:
 maintainers of: engines, LaTeX, GUST font, asymptote, context, texworks
 other parts of collection: protext, ctan, mactex.
 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.

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


Then, the next day, start building tlpretest:

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

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

1b. Set up tlpretest:
Better to empty tlpretest, touch texlive.tlpdb; then --recreate should suffice.
Update /home/ftp/texlive/tlpretest/README.
Update pretest.html, notably including major changes this year.
diff new and old bindirs to see if there are interesting new programs:
  \ls $lb >/tmp/now
  \ls $ib >/tmp/new
  comm -3 /tmp/now /tmp/new >/tmp/cm

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.  Or disable if you prefer.)
First build happens below.

3. option adjustrepo 0 in tl-update-tlnet, since pretest shouldn't go
to CTAN for updates.

4a. When starting trial builds (or earlier):
Build/source/{version.ac,texk/{kpathsea,ptexenc}/version.ac: no /dev
Also good to do other version/year updates as below.

4b. When starting pretest, basic updates for release year:
Master/.mkisofsrc
Master/release-texlive.txt
Master/tlpkg/TeXLive/TLConfig.pm (including MinRelease)
Master/tlpkg/bin/tl-update-tlnet
Master/tlpkg/bin/tl-update-images
Master/tlpkg/installer/texlive.png (tlpkg/doc/texlive-installer-graphic.xcf)
Master/texmf-dist/web2c/texmfcnf.lua
Master/texmf-dist/web2c/texmf.cnf  # from Build/.../kpathsea
(check/update copyright years in *.pm, tlmgr*, install-tl, tlpkg/installer)

5. Ensure version numbers in sources are updated; see list below.
Then commit new binaries with tl-update-bindir.

6. After committing, run tex \\end to check that mktexfmt works. 
Also run fmtutil --all to check that all formats build, no config file
problems.  Then, so things will get redone later as another check:
  rm -rf ~/.texlive`date +%Y`  # the new one

7. Check for Build-maintained updates to config files, etc.
(and might have to merge back if Master was mistakenly updated):
  diff -ru0 --exclude=man --exclude=info \
    Build/source/inst/texmf-dist Master/texmf-dist
for p in *conv hbf2gf; do cp /home/ftp/mirror/rsync.tex.ac.uk/CTAN/language/chinese/CJK/cjk-4.8.4/doc/pdf/$p.pdf $p; done

8. Now, try a first update of tlpretest:
  force_rebuild=true cron.tl
This will fail because pretest is not set up, but that's ok; the idea is
to check the output and ensure all is as basically ok.

9. After that trial build, set
recreate=--recreate  # just once! to get catalogue updates, and again:
  mkdir /home/ftp/texlive/tlpretest/tlpkg
  touch !$/texlive.tlpdb
  force_rebuild=true cron.tl

A. After tlnet freeze:
  Run tl-update-linked-scripts for consistency.
  In Master/tlpkg, update bundled Windows programs as needed:
    dviout texworks tlgs tlperl tlpsv
  In tlpkg/installer, update xz and wget if needed
  Update readme-html.dir/readme.en.html if needed
    run tlpkg/bin/htmltext to create readme-txt.dir/README.EN.
  Update texcollection DVD text:
    http://tug.org/texcollection/
    http://puszcza.gnu.org.ua/projects/texcollection/

A.0. Specifics for tlperl update:
  cd $pg
  find tlperl -type f | \grep -v README.TEXLIVE | sort >/tmp/now
  tar tf newperl.tgz | \grep -v /\$ | sort >/tmp/new
    # or zipinfo -1 newperl.zip
  tar xf ..., or unzip -q ...
  comm -13 /tmp/now /tmp/new >/tmp/c2
  comm -23 /tmp/now /tmp/new >/tmp/c1
  svn rm `cat /tmp/c1`
  svn add --parents --no-auto-props `cat /tmp/c2`
  svn status | fgrep \? # shouldn't be any
  find tlperl -name \*.dll | xargs svn propset svn:executable 1
  find tlperl -type d -empty | xargs svn rm  # repeat until no output
  update tlperl/README.TEXLIVE
  svn commit when ready ...

B. Build a test ISO image for initial TeX Collection testing:
  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.
  Can disable image building again after the initial build for a while.


M. As work proceeds, update the doc:
  MetaPost (in texmf-dist), other engine (in source) NEWS.
  Ensure all engine manuals updated in texmf-dist.
  Update texlive-en.tex (+ .pdf, .html), tell tldoc to translate.
  Update tlbuild.texi.
  Consider updates of core man pages in Build/source/texk/web2c/man.
  Remake updmap,fmtutil man pages with help2man:
    make -C Build/source/Work/texk/texlive/tl_scripts xupdmap.1 xfmtutil.1
    They must be moved from /tmp into Master by hand.
    Also update ~www/texlive/doc/*.html: groff -mandoc -Thtml fmtutil.1
  Texinfo manuals from Build to Master:
    tl-update-txi  # then commit in texmf-dist/doc
  Man pages from Build to Master (after doing a build):
    tl-update-man
    # then run make in texmf-dist/doc/man
    # and check /tmp/so.rules against man1/Makefile

N. Really test during pretest (really! don't leave it for knuth!):
  .fmt's sharable across endian-different platforms (including luatex).
  interactive mf '\drawdot (50,50); showit;'  % and from * prompt

O. Just before the final pretest (i.e., to-be-published) build:
  option adjustrepo 1 in tl-update-tlnet, else install-tl-unx won't go to ctan
  Update Master/source:
    xz wget w32tex-src texlive*source mactexdoc install-tl-unx.tar.gz 
    tlmgr version number in texmf-dist/scripts/texlive/NEWS 
  Tell developers no more commits: akira, takuji, luigi, taco.
  Put date into NEWS and ChangeLog files.

P. After final build, to do total freeze:
  In cron.tl, set *_frozen=true.
  Probably also just disable the cron entry.


When finalizing sources (any time in the new year, can be early, before
initial builds in any case):
- update version numbers, years, and copyright years in:
  top level version.ac
  dvipdfm-x:configure.ac dvipdfmx.c xbb.c
  dvips:    configure.ac NEWS dvips.c dvips.h afm2tfm.c dvips.texi
  kpathsea: version.ac NEWS kpsewhich.c doc/kpathsea.texi texmf.cnf
  ptexenc:  version.ac
  web2c:    NEWS doc/web2c.texi ptexdir/ptex-base.ch,ptex_version.h
            pdftexdir/pdftex.web pdftexdir/pdftex_version.h
  texk/*/version.ac, libs/*/version.ac, utils/*/version.ac
  then reautoconf (6min), rebuild.
  install-tl, tlmgr.pl (copyright only)
  check *.c *.h sources in above for needed copyright year updates too.
  run ~karl/bin/tlversions to see+compare engine/etc. versions
- if new kpathsea file types (kpsewhich --help-formats), update kpathsea.texi.
- ask tldistro for patches.


Making the big release:

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

hx=/home/ftp/historic/systems/texlive
prev=2015
this=2016
mkdir $hx/$this

cd /home/ftp/texlive/Images
cp README.html $hx/$prev/
mv *.iso* *.torrent* $hx/$prev/
mv test/texlive2*.iso .
mv test/texlive*.tar.xz* $hx/$this/	# tar version only in historic
update README (touch even if no real changes needed)
   and test/README (pretest over)

- mactex (from tlpretest)
hm=/home/ftp/historic/systems/mactex
mkdir $hm/$prev
cd ~ftp/tex/mactex
mv *-*.pkg* $hm/$prev
mv ~ftp/texlive/tlpretest/mactex*pkg .
ln -s mactex-20*.pkg MacTeX.pkg 
ln -s mactex-basic* BasicTeX.pkg
ln -s mactex-ghost* Ghostscript.pkg
for p in *.pkg; do md5sum $p >$p.md5; done  # used on mactex web pages
mkdir $hm/$this
cp Extras*pdf MacTeXtras-*.zip $hm/$this

- rest of 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 (touch even if no real changes needed)
   and ../tlpretest/README (pretest over)
cp install-tl-unx.tar.gz $hx/$this/

- update local CTAN area to avoid mirroring everything back again:
cy=/home/ftp/tex-archive/systems
fx=/home/ftp/tex
rm -rf $cy/texlive/tlnet/*; cp -ar * $cy/texlive/tlnet/
rm $cy/texlive/Images/*; cp -a ../Images/*.* $cy/texlive/Images/
rm $cy/texlive/Source/*
cp -a $fx/mactex/* $cy/mac/mactex/
cp -a $fx/protext/dist/* $cy/windows/protext/ # probably already done

- historic copy of TL web pages:
cd /home/httpd/html/texlive
mkdir $hx/$prev/web
cp *.html !$  # remove tugstyle.css ref from bugs.html

- tug.org stuff:
change fstab 
mount /mnt/tl
cd /mnt/tl
perl install-tl # do full install to default location.
rm /usr/local/texlive-rel; ln -s texlive/$this /usr/local/texlive-rel
newsrc=!$/source
mkdir $newsrc
cp source/{install-tl,texlive,w32tex}*.tar.?z $newsrc
mount /home/ftp/texlive/Contents/live
cd && umount /mnt/tl

update historic/systems with final proTeXt, when ready.
  https://bscw.fernuni-hagen.de
  ftp://ftp.fernuni-hagen.de/pub/windows/win32/ProTeXt/
update ~www/texlive web pages (search for $prev and $prev-1):
  acquire* - general
  bugs.html - general, also case of $prevprev at bottom
  doc.html - platform list, translation list
  pretest.html - done for this year, maybe transfer bugs
  quickinstall.html - paths
  upgrade.html - whether possible or not
  tlmgr-news.html - from texmf-dist/scripts/texlive/NEWS
  index.html - 
check for new Texinfo manuals to link to html versions:
  ~www/texinfohtml/
further web updates below.

- announcements:
CTAN @ ISO update, re-enabling tlnet mirroring.
Dick @ updating MacTeX.
Martin @ torrents.
Siep @ w32client.html, Norbert @ debian,updmap-kanji.html.
Nikola @ FreeBSD notes linked on bugs.html.
pdftex maintainers @ updating pdftex sources with sync-pdftex.sh.

- make tag + branch:
(determine revision number from svn log, in case commits were mistakenly made)
svn copy -r 41285 \
 -m'texlive-2016.0 tag based on r41285' \
 svn://tug.org/texlive/trunk svn://tug.org/texlive/tags/texlive-2016.0
svn copy -r 41285 \
  -m'branch2015 branch based on r41285' \
  svn://tug.org/texlive/trunk svn://tug.org/texlive/branches/branch2016

  It's the same command, just different destinations.
  http://svnbook.red-bean.com/en/1.8/svn.branchmerge.html

  We 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/branch$this/Build/source . >&out

   When bug fixes are done, i.e., at another stable point, make another tag:
#svn copy -r 30858 -m'texlive-2013.1 tag based on r30858, with rebuilt binaries (only)' \
#  svn://tug.org/texlive/trunk svn://tug.org/texlive/tags/texlive-2013.1

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

pretest=
images_frozen=true
net_frozen=false
all_frozen=false
