# Configuration Cheat Sheet

This is a cheat sheet for the Gitea configuration file. It contains most of the settings
that can be configured as well as their default values.

Any changes to the Gitea configuration file should be made in `custom/conf/app.ini`
or any corresponding location. When installing from a distribution, this will
typically be found at `/etc/gitea/conf/app.ini`.

The defaults provided here are best-effort (not built automatically). They are
accurately recorded in [app.example.ini](https://github.com/go-gitea/gitea/blob/master/custom/conf/app.example.ini)
(s/master/\<tag|release\>). Any string in the format `%(X)s` is a feature powered
by [ini](https://github.com/go-ini/ini/#recursive-values), for reading values recursively.

Values containing `#` or `;` must be quoted using `` ` `` or `"""`.

**Note:** A full restart is required for Gitea configuration changes to take effect.

## Overall (`DEFAULT`)

- `APP_NAME`: **Gitea: Git with a cup of tea**: Application name, used in the page title.
- `RUN_USER`: **git**: The user Gitea will run as. This should be a dedicated system
   (non-user) account. Setting this incorrectly will cause Gitea to not start.
- `RUN_MODE`: **prod**: Application run mode, affects performance and debugging. Either "dev", "prod" or "test".

## Repository (`repository`)

- `ROOT`: **data/gitea-repositories/**: Root path for storing all repository data. It must be
   an absolute path. By default it is stored in a sub-directory of `APP_DATA_PATH`.
- `SCRIPT_TYPE`: **bash**: The script type this server supports. Usually this is `bash`,
   but some users report that only `sh` is available.
- `DETECTED_CHARSETS_ORDER`: **UTF-8, UTF-16BE, UTF-16LE, UTF-32BE, UTF-32LE, ISO-8859, windows-1252, ISO-8859, windows-1250, ISO-8859, ISO-8859, ISO-8859, windows-1253, ISO-8859, windows-1255, ISO-8859, windows-1251, windows-1256, KOI8-R, ISO-8859, windows-1254, Shift_JIS, GB18030, EUC-JP, EUC-KR, Big5, ISO-2022, ISO-2022, ISO-2022, IBM424_rtl, IBM424_ltr, IBM420_rtl, IBM420_ltr**: Tie-break order of detected charsets - if the detected charsets have equal confidence, charsets earlier in the list will be chosen in preference to those later. Adding `defaults` will place the unnamed charsets at that point.

  - Valid values for MySQL:
     - `true`: Enable TLS with verification of the database server certificate against its root certificate. When selecting this option make sure that the root certificate required to validate the database server certificate (e.g. the CA certificate) is on the system certificate store of both the database and Gitea servers. See your system documentation for instructions on how to add a CA certificate to the certificate store.
     - `false`: Disable TLS.
     - `disable`: Alias for `false`, for compatibility with PostgreSQL.
     - `skip-verify`: Enable TLS without database server certificate verification. Use this option if you have self-signed or invalid certificate on the database server.
     - `prefer`: Enable TLS with fallback to non-TLS connection.
  - Valid values for PostgreSQL:
     - `disable`: Disable TLS.
     - `require`: Enable TLS without any verifications.
     - `verify-ca`: Enable TLS with verification of the database server certificate against its root certificate.

- `LOG_SQL`: **true**: Log the executed SQL.
- `DB_RETRIES`: **10**: How many ORM init / DB connect attempts allowed.
- `DB_RETRY_BACKOFF`: **3s**: time.Duration to wait before trying another ORM init / DB connect attempt, if failure occured.
- `MAX_OPEN_CONNS` **0**: Database maximum open connections - default is 0, meaning there is no limit.
- `MAX_IDLE_CONNS` **2**: Max idle database connections on connnection pool, default is 2 - this will be capped to `MAX_OPEN_CONNS`.
- `CONN_MAX_LIFETIME` **0 or 3s**: Sets the maximum amount of time a DB connection may be reused - default is 0, meaning there is no limit (except on MySQL where it is 3s - see #6804 & #7071).

Please see #8540 & #8273 for further discussion of the appropriate values for `MAX_OPEN_CONNS`, `MAX_IDLE_CONNS` & `CONN_MAX_LIFETIME` and their

NEED_POSTPROCESS = true
FILE_EXTENSIONS = .adoc,.asciidoc
RENDER_COMMAND = "asciidoc --out-file=- -"
IS_INPUT_FILE = false
```

   command. Multiple extentions needs a comma as splitter.
- RENDER\_COMMAND: External command to render all matching extensions.
- IS\_INPUT\_FILE: **false** Input is not a standard input but a file param followed `RENDER_COMMAND`.

Two special environment variables are passed to the render command:

- `GITEA_PREFIX_RAW`, which contains the current URL prefix in the `raw` path tree. To be used as prefix for image paths.


Gitea supports customizing the sanitization policy for rendered HTML. The example below will support KaTeX output from pandoc.

```ini
[markup.sanitizer.TeX]
; Pandoc renders TeX segments as <span>s with the "math" class, optionally
; with "inline" or "display" classes depending on context.
ELEMENT = span
ALLOW_ATTR = class
REGEXP = ^\s*((math(\s+|$)|inline(\s+|$)|display(\s+|$)))+
ALLOW_DATA_URI_IMAGES = true
```

 - `ELEMENT`: The element this policy applies to. Must be non-empty.
 - `ALLOW_ATTR`: The attribute this policy allows. Must be non-empty.
 - `REGEXP`: A regex to match the contents of the attribute against. Must be present but may be empty for unconditional whitelisting of this attribute.
 - `ALLOW_DATA_URI_IMAGES`: **false** Allow data uri images (`<img src="data:image/png;base64,..."/>`).

Multiple sanitisation rules can be defined by adding unique subsections, e.g. `[markup.sanitizer.TeX-2]`.
To apply a sanitisation rules only for a specify external renderer they must use the renderer name, e.g. `[markup.sanitizer.asciidoc.rule-1]`.
If the rule is defined above the renderer ini section or the name does not match a renderer it is applied to every renderer.
