# v1.5.0rc1 アップデートメモ
完全に俺メモです。os は gentoo で、非docker環境の v1.4.7 mastodonです。
v1.5.0rc1 で必要になると言われている libidn11-dev は gentoo 的には考えなくてよさそう。

```
# emerge -pv libidn libidn2

These are the packages that would be merged, in order:

Calculating dependencies... done!
[ebuild   R    ] net-dns/libidn-1.33::gentoo  USE="nls -doc -emacs -java -mono -static-libs" 0 KiB
[ebuild   R    ] net-dns/libidn2-0.16-r1::gentoo  USE="-static-libs" 0 KiB

Total: 2 packages (2 reinstalls), Size of downloads: 0 KiB
```

## とりあえず検証用インスタンスなので問答無用で停止する
```
# run_init /etc/init.d/nginx stop
# run_init /etc/init.d/mastodon-web stop
# run_init /etc/init.d/mastodon-streaming stop
# run_init /etc/init.d/mastodon-sidekiq stop
```

## バックアップ
```
# su - mastodon -s /bin/bash
$ cd live
$ cp .env.production ../
```

## 必要なものを揃える
```
$ bundle install
 :
 :
The latest bundler is 1.15.3, but you are currently running 1.15.2.
To update, run `gem install bundler`
```

そもそも bundler が古いとか文句言われた……
```
$ gem install bundler
```

つづいて `yarn`

```
$ yarn install
```
長い。

## .env.production
環境変数が2つ追加。設定する SecureRandom 的な文字列を生成する。

落ちた……

```
$ df -h .
Filesystem                           Size  Used Avail Use% Mounted on
/dev/mapper/vg001-lv002  2.0G  1.5G  377M  80% /home/mastodon
```

なるほど、足してみる。
```
 # lvextend  /dev/vg001/lv002 -L2.5g
  Size of logical volume vg001/lv002 changed from 2.00 GiB (16 extents) to 2.50 GiB (20 extents).
  Logical volume lv002 successfully resized.
 # resize2fs /dev/vg001/lv002
resize2fs 1.43.3 (04-Sep-2016)
Filesystem at /dev/vg001/lv002 is mounted on /home/mastodon; on-line resizing required
old_desc_blocks = 1, new_desc_blocks = 1
The filesystem on /dev/vg001/lv002 is now 655360 (4k) blocks long.
```

もう1回やってみる。
```
$ RAILS_ENV=production bundle exec rake mastodon:webpush:g
enerate_vapid_key
VAPID_PRIVATE_KEY=e-------------------------------------------=
VAPID_PUBLIC_KEY=---------------------------------------------------------------------------------------=
```
通った……意外と容量食うのねｗ

## db:migrate
```
$ RAILS_ENV=production bundle exec rails db:migrate
```

## assets:precompile
落ちたｗ 今日はここまでかぐぬぬ……。

## sw.js
```
       location ~ ^/sw\.js {
                add_header              Cache-Control "max-age=0";
       }
```

nginx の設定にこんなのいれる。<del>これちょっと要調査。</del>


[修正] リクエストは `/public/sw.js` ではなく `/sw.js` に来るので `location` を修正。
