# Breaking: #107537 - Changes in URL generation of system resources {#breaking-107537-1760339938}

See [forge#107537](https://forge.typo3.org/issues/107537)

## Description {#description}

The following changes are considered breaking, although their impact is
expected to be very low.

-   TypoScript getData function `path` previously returned a
    relative URL and now returns an absolute URL (prepended with
    `absRefPrefix`).
-   Access to FAL storages via relative path (`fileadmin/templates/main.css`)
    is limited to the default storage defined in `$GLOBALS['TYPO3_CONF_VARS']['BE']['fileadminDir']`.
-   All generated system resource URLs now include cache busting.
-   Adding custom query strings to resource identifiers no longer disables cache
    busting — both are now applied.

### getText "path" in TypoScript {#breaking-107537-gettext-path}

**EXT:my_extension/Configuration/TypoScript/setup.typoscript**

```typoscript
page.20 = TEXT
page.20 {
    data = path : EXT:core/Resources/Public/Icons/Extension.svg
}
```

**Result (TYPO3 classic mode – note the leading "/")**

```text
"path" result before: typo3/sysext/core/Resources/Public/Icons/Extension.svg
"path" result now: /typo3/sysext/core/Resources/Public/Icons/Extension.svg
```

**Result (TYPO3 Composer mode – note the leading "/")**

```text
"path" result before: _assets/5f237792cbcdc97cfceade1e16ea33d7/Icons/Extension.svg
"path" result now: /_assets/5f237792cbcdc97cfceade1e16ea33d7/Icons/Extension.svg
```

### Relative path to FAL Storage {#breaking-107537-relative-fal-resource}

Referencing resources via relative path does only work for the default FAL storage
defined in `$GLOBALS['TYPO3_CONF_VARS']['BE']['fileadminDir']`.
This means if you have other local FAL storages configured, you need to use the FAL resource syntax
(e.g. `FAL:42:/path/to/file.css`) to reference files in such storage instead of using relative paths
(e.g. `my-other-fileadmin/path/to/file.css`).
It is generally recommended to use explicit resource identifiers (App resources or FAL resources),
instead of relative paths.

### All generated URLs now contain cache busting {#breaking-107537-cachebusting}

All generated resource URLs now include cache busting.
For example, icon URLs that previously had no cache busting will now contain a
cache-busting query string.

### Additional query strings applied to the resource identifier {#breaking-107537-querystrings}

When adding custom query strings to resource identifiers, TYPO3 previously
disabled cache busting.

Now, both the custom query string and the cache-busting parameter are applied.
If custom query strings were used as manual cache busters, you can now remove
them safely.

**EXT:my_extension/Configuration/TypoScript/setup.typoscript**

```typoscript
page.20 = TEXT
page.20 {
    data = asset : EXT:core/Resources/Public/Icons/Extension.svg?v=1234
}
```

**Result**

```text
result before: /typo3/sysext/core/Resources/Public/Icons/Extension.svg?v=1234
result now: /typo3/sysext/core/Resources/Public/Icons/Extension.svg?v=1234&1709051481
```

## Impact {#impact}

### getText "path" in TypoScript {#breaking-107537-impact-gettext-path}

All usages of `path` in TypoScript `data` now resolve
to absolute URLs instead of relative ones.

### Relative path to FAL Storage {#breaking-107537-impact-relative-fal-resource}

In installations referencing resources in additional local FAL storages using
a relative path syntax, an exception is thrown.

### All generated URLs now contain cache busting {#breaking-107537-impact-cachebusting}

Generated URLs differ slightly from previous TYPO3 versions, especially when
cache busting was not applied before.

### Additional query strings applied to the resource identifier {#breaking-107537-impact-querystrings}

URLs now include both the original query string and the cache-busting
parameter, resulting in different output compared to earlier TYPO3 versions.

## Affected installations {#affected-installations}

### getText "path" in TypoScript {#breaking-107537-affected-gettext-path}

All installations using `path` in TypoScript `data`.

### Relative path to FAL Storage {#breaking-107537-affected-relative-fal-resource}

All installations referencing resources in additional local FAL storages using
a relative path syntax (e.g. `my-other-fileadmin/path/to/file.css`).

### All generated URLs now contain cache busting {#breaking-107537-affected-cachebusting}

All installations having third party code, that misuses generated URLs
to assume file system paths from them.

### Additional query strings applied to the resource identifier {#breaking-107537-affected-querystrings}

All installations using resource identifiers with custom query strings, for
example:

`EXT:foo/Resources/Public/rte.css?v=123`

## Migration {#migration}

### Relative path to FAL Storage {#relative-path-to-fal-storage-3}

Either convert the relative path to a FAL resource like so:

`FAL:1:/path/to/file.css`

Alternatively it is possible to convert it to a resource URI:

`URI:/my-other-fileadmin/path/to/file.css`

The first will add cache busting, the latter will use the URI as is.
