map-release

This is out of data, nowadays we use Django to automate this. Old process documented for posteriority:

Map release process on DDNet
============================

Example for Kobra 4
Regular release time is 18-20 if we have 1 release for the day. If we have 2 releases, the first at 12-14, the second 18-20.
Planned map releases: http://forum.ddnet.tw/viewtopic.php?f=9&t=1474
Pre-requirements:
  - SSH to all DDNet servers via public key, mod account in forum
  - You need imagemagick, pngnq, optipng, clusterssh installed locally
  - libtw2 for ddnet_properties
  - SSH config (~/.ssh/config):

    Host chn.ddnet.tw
      ProxyCommand ssh -q usa.ddnet.tw nc -q0 chn.ddnet.tw 22
      User deen
      Port 22

    Host ddnet.tw *.ddnet.tw
      User teeworlds
      Port 6546

1. map properties
  $ cd git/libtw2
  $ cargo build --release
  $ target/release/ddnet_properties Kobra\ 4.map Kobra\ 4.msgpack
  $ scp Kobra\ 4.msgpack ddnet.tw:servers/maps

2. screenshot
  - Make a screenshot of the map on test server at 1440x900, HD on, no chat, no HUD, logo or start area or spawn, whatever looks best
    config (run with ./DDNet -f foo.cfg):

    gfx_fullscreen 0
    gfx_screen_width 1440
    gfx_screen_height 900
    gfx_high_detail 1
    gfx_texture_quality 1
    cl_showhud 0
    cl_showchat 0
    cl_showkillmessages 0

  - Screenshot file name: Everything that's not a-z,A-Z,0-9 gets converted to an underline
  $ mv screenshot-20150815@121626.png Kobra_4.png
  $ mkdir -p conv; for i in *png; do convert $i -resize 25% conv/$i; zopflipng -m --prefix conv/$i; mv conv/zopfli_$i conv/$i; done; scp conv/* ddnet:/var/www/ranks/maps/; rm conv/*png; mv *png ~/git/ddnet/screenshots
  - I store full size screenshots in git/ddnet/screenshots in case we ever need them (unused so far)

3. release the map
  $ ssh ddnet
  $ cd servers
  $ mv test/maps/Kobra\ 4.cfg maps
  - Check if the config is actually ok
  $ git add maps/Kobra\ 4.cfg
  $ mv test/maps/Kobra\ 4.map maps
  - iMTG maps are in secret2/maps, race maps are in secret/maps
  $ git add maps/Kobra\ 4.map
  $ vim types/novice/maps
  - Add a line like 4|Kobra 4|Zerodin
    First field is the number of stars, check the map topic for that
    Last field is the names of the mappers: First, Second, Third & Last
  $ ./git-update.sh
  - Wait until FRA has been finished (main server)

4. check if it's released ok
  - Check on server whether the map is votable
  - Check /mapinfo and/or /map
  - Check http://ddnet.tw/releases/ (/ranks and /mappers get updated every 20 min)

5. announce release with clusterssh
  $ cat ~/.clusterssh/clusters
  ddnet ddnet.tw ger.ddnet.tw ger2.ddnet.tw rus.ddnet.tw usa.ddnet.tw chn.ddnet.tw chl.ddnet.tw zaf.ddnet.tw can.ddnet.tw bra.ddnet.tw irn.ddnet.tw
  $ cssh ddnet
  - 10 terminal windows open
  $ abc
  bc>
  - Wait until it shows "bc>" on all servers, otherwise text will be cut off
  bc> New map "Kobra 4" by Zerodin just released on Novice! <ENTER>

6. Clean up forum
  - Go to http://forum.ddnet.tw/viewtopic.php?f=9&t=1474
  - Move the topic of the map to archive
  - Write in the topic of the map that the map has been released
  - Remove the map from Planned Releases
