# Introduction
This document covers basic upgrade notes for major ENiGMA½ version updates.

> :information_source: **Be sure to read the version-to-version upgrade notes below** for each upgrade!

# Before Upgrading
* Always back up your system! (See [Administration](./docs/admin/administration.md))
* Seriously, always back up your system!

# General Notes
## Configuration File Updates
In general, look at template menu files in `misc/menu_templates`, and `config_template.in.hjson` as well as the default `luciano_blocktronics/theme.hjson` files when you update. <u>These files may come with new sections you wish to merge into your system!</u>

### Menus & Theme Updates
Upgrades often come with changes to the default menu templates found in `misc/menu_templates`. You can use these as references for changes and additions to the default menu sets. This also applies to the default `luciano_blocktronics` theme and it's `theme.hjson` file.

See [Updating](./docs/admin/updating.md) for details on menu files/etc.

# Upgrading the Code
Upgrading from GitHub is easy:

```bash
cd /path/to/enigma-bbs
git pull
rm -rf npm_modules # do this any time you update Node.js itself
npm install # or simply 'yarn'
```

# Problems
1. Check [TROUBLESHOOTING](TROUBLESHOOTING.md) first.
2. Report your issue on Xibalba BBS, hop in #`enigma-bbs` on FreeNode and chat, or [file a issue on GitHub](https://github.com/NuSkooler/enigma-bbs/issues) if you believe you've found a bug or missing feature.

# Version to Version Notes
> :warning: Be sure to inspect these notes during any upgrades!

## 0.0.13-beta to 0.0.14-beta
* A new ActivityPub menu template has been created. Upgrades will **not** have this file present so you will need to copy the template to your `config/menus` directory and rename it appropriately (it must match the `include` statement in your main `menu.hjson` file). Example:
```bash
cp ./misc/menu_templates/activitypub.in.hjson ./config/menus/my_board_name-activitypub.hjson`
```

This will expose the default ActivityPub setup. Enabling ActivityPub functionality requires the web server enabled and ActivityPub itself enabled in your `config.hjson`.


## 0.0.12-beta to 0.0.13-beta
* To enable the new Waiting for Caller (WFC) support, please see [WFC](docs/modding/wfc.md).
* :exclamation: The SSH server's `ssh2` module has gone through a major upgrade. Existing users will need to comment out two SSH KEX algorithms from their `config.hjson` if present else clients such as NetRunner will not be able to connect over SSH. Comment out `diffie-hellman-group-exchange-sha256` and `diffie-hellman-group-exchange-sha1`
* Gopher configuration change. See [WHATSNEW](WHATSNEW.md)
* All features and changes are backwards compatible. There are a few new configuration options in a new `term` section in the configuration. These are all optional, but include the following options in case you use them:

```hjson
{
  term: {
    // checkUtf8Encoding requires the use of cursor
    // position reports, which are not supported on all terminals.
    // Using this with a terminal that does not support cursor
    // position reports results in a 2 second delay during the
    // connect process, but provides better autoconfiguration of utf-8
    checkUtf8Encoding: true


    // Checking the ANSI home position also requires the use of
    // cursor position reports, which are not supported on all
    /// terminals. Using this with a terminal that does not support
    // cursor position reports results in a 3 second delay during
    // the connect process, but works around positioning problems with
    // non-standard terminals.
    checkAnsiHomePosition: true
  }
}
```

In addition to these, there are also new options for `term.cp437TermList` and `term.utf8TermList`. Under most circumstances these should not need to be changed. If you want to customize these lists, more information is available in `config_default.js`

## 0.0.11-beta to 0.0.12-beta
* Be aware that `master` is now mainline! This means all `git pull`'s will yield the latest version. See [WHATSNEW](WHATSNEW.md) for more information.
* **BREAKING CHANGE** There is no longer a `prompt.hjson` file. Prompts are now simply part of the menu set in the `prompts` section. If you have an existing system you will need to add your `prompt.hjson` to your `menu.hjson`'s `includes` section at a minimum. Example:
```hjson
// menu.hjson
{
    includes: [
        my-prompts.hjson // ref your old prompts here
    ]
}
```
* A set of database fixes were made that cause some records to be properly cleaned up when e.g. deleting a file. Existing `file.db` databases will need to be updated **manually**. Note that this applies to users upgrading within 0.0.12-beta as well:
1. **Make a backup of your file.db!**
2. Shut down ENiGMA.
3. From the enigma-bbs directory:
```
sqlite3 db/file.sqlite3 < ./misc/update/tables_update_2020-11-29.sql
```

## 0.0.10-alpha to 0.0.11-beta
* Node.js 12.x LTS is now in use. Follow standard Node.js upgrade procedures (e.g.: `nvm install 12 && nvm use 12`).

## 0.0.9-alpha to 0.0.10-alpha
* Security related files such as private keys and certs are now looked for in `config/security` by default.
* Default archive handler for zip files has switched to InfoZip due to a bug in the latest p7Zip packages causing "volume not found" errors. Ensure you have the InfoZip `zip` and `unzip` commands in ENiGMA's path. You can switch back to 7Zip by overriding `archiveHandler` for `application/zip` in your `config.hjson` under `fileTypes` to `7Zip`.

## 0.0.8-alpha to 0.0.9-alpha
* Development is now against Node.js 10.x LTS. Follow your standard upgrade path to update to Node 10.x before using 0.0.9-alpha!
* The property `justify` found on various views previously had `left` and `right` values swapped (oops!); you will need to adjust any custom `theme.hjson` that use one or the other and swap them as well.
* Possible breaking changes in FSE: The MCI code `%TL13` for error indicator is now `%TL4`. This is part of a cleanup and standardization on "custom ranges". You may need to update your `theme.hjson` and related artwork.
* Removed view width auto-size: Some views still can auto-size their height, but in general you should be explicit in your themes
* More standardization using "custom ranges" and `itemFormat` / `focusItemFormat` semantics. Update your themes!
* In addition to using `itemFormat`, the `onelinerz` module uses `userName` vs `username` (note the case) to match other modules
* `loginServers.webSocket` configuration block has changed to be more consistent with other servers. Example:
```
webSocket: {
    ws: {
        enabled: true
    }
    wss: {
        enabled: true
        port: 1234
    }
    proxied: true	//	X-Forwarded-Proto: https support
}
```
* The module export `registerEvents` has been deprecated. If you have a module that depends on this, use the new more generic `moduleInitialize` export instead.
* The `system.db` `user_event_log` table has been updated to include a unique session ID. Previously this table was not used, but you will need to perform a slight maintenance task before it can be properly used. After updating to `0.0.9-alpha`, please run the following: `sqlite3 db/system.db DROP TABLE user_event_log;`. The new table format will be created and used at startup.
* If you have art configured for message conference or area selection via the `art` configuration value, you will need to include a `show_art` menu reference. Defaulted to `changeMessageConfPreArt` for conferences and `changeMessageAreaPreArt` for areas & included in the example `menu.hjson`.
* Config `defaults` section was theme related and as such, has been renamed to `theme`. `defaults.theme` is now `theme.default`, and `preLoginTheme` is now `theme.preLogin`. See `config.js` if this isn't clear as mud.
* Similar to the last item, `defaults.general.passwordChar` in `theme.hjson` is now just `defaults.passwordChar`.


## 0.0.7-alpha to 0.0.8-alpha
ENiGMA 0.0.8-alpha comes with some structure changes:
* Configuration files are defaulted to `./config`. Related, the `--config` option now points to a configuration **directory**
* `./mods/art` has been moved to `./art/general`
* `./mods` is now reserved for actual user addon modules
* Themes have been moved from `./mods/themes` to `./art/themes`

With the change to the `./mods` directory, `@systemModule` is now implied for `module` declarations in `menu.hjson`. To use a user module in `./mods` you must specify `@userModule`!

With the above changes, you'll need to to at least:
* Move your `~/.config/enigma-bbs/config.hjson` to `./config/config.hjson` or utlize the `--config` option.
* Move your `prompt.hjson` and `menu.hjson` (e.g. `myboardname.hjson`) to `./config`
* Move any non-theme art files, and theme directories to their appropriate locations mentioned above
* Move any module directories such as `message_post_evt` to `./mods/`
* Move any certificates, pub/private keys, etc. from `./misc` to `./config`
* Specify user modules as `@userModule:my_module_name`

## 0.0.6-alpha to 0.0.7-alpha
No issues

## 0.0.5-alpha to 0.0.6-alpha
No issues

## 0.0.4-alpha to 0.0.5-alpha
No issues

## 0.0.1-alpha to 0.0.4-alpha
### Node.js 6.x+ LTS is now **required**
You will need to upgrade Node.js to [6.x+](https://github.com/nodejs/node/blob/master/doc/changelogs/CHANGELOG_V6.md). If using [nvm](https://github.com/creationix/nvm) (you should be!) the process will go something like this:
```bash
nvm install 6
nvm alias default 6
```

### ES6
Newly written code will use ES6 and a lot of code has started the migration process. Of note is the `MenuModule` class. If you have created a mod that inherits from `MenuModule`, you will need to upgrade your class to ES6.

### Manual Database Upgrade
A few upgrades need to be made to your SQLite databases:

```bash
rm db/file.sqltie3 # safe to delete this time as it was not used previously
sqlite3 db/message.sqlite
sqlite> INSERT INTO message_fts(message_fts) VALUES('rebuild');
```

### Archiver Changes
If you have overridden or made additions to archivers in your `config.hjson` you will need to update them. See [Archive Configuration](docs/archive.md) and `core/config.js`

### File Base Configuration
As 0.0.4-alpha contains file bases, you'll want to create a suitable configuration if you wish to use the feature. See [File Base Configuration](docs/file_base.md).
