chore(deps): bump com.squareup.okhttp3:okhttp from 4.11.0 to 5.2.1 in /backend

[dependabot[bot]]

Bumps com.squareup.okhttp3:okhttp from 4.11.0 to 5.2.1.

Changelog

Sourced from com.squareup.okhttp3:okhttp's changelog.

Version 5.2.1

2025-10-09

• Fix: Don't crash when calling Socket.shutdownOutput() or shutdownInput() on an SSLSocket on Android API 21 through 23. This method throws an UnsupportedOperationException, so we now catch that and close the underlying stream instead.

• Upgrade: [Okio 3.16.1][okio_3_16_1].

Version 5.2.0

2025-10-07

• New: Support [HTTP 101] responses with Response.socket. This mechanism is only supported on HTTP/1.1. We also reimplemented our websocket client to use this new mechanism.

• New: The okhttp-zstd module negotiates [Zstandard (zstd)][zstd] compression with servers that support it. It integrates a new (unstable) [ZSTD-KMP] library, also from Square. Enable it like this:

  val client = OkHttpClient.Builder()
    .addInterceptor(CompressionInterceptor(Zstd, Gzip))
    .build()
  

• New: Support the QUERY HTTP method. You will need to set the Request.cacheUrlOverride property to cache calls made with this method. The RequestBody.sha256() may be helpful here; use it to compose a cache URL from the query body.

• New: Publish events when calls must wait to execute. EventListener.dispatcherQueueStart() is invoked when a call starts waiting, and dispatcherQueueEnd() is invoked when it's done.

• New: Request.toCurl() returns a copy-pasteable [curl] command consistent with Chrome’s and Firefox’s ‘copy as cURL’ features.

• New: Support [JPMS]. We replaced our Automatic-Module-Name metadata with proper module-info.java files.

• Fix: Recover gracefully when worker threads are interrupted. When we introduced fast fallback in OkHttp 5.0, we started using background threads while connecting. Sadly that code didn't handle interruptions well. This is now fixed.

• Upgrade: [Kotlin 2.2.20][kotlin_2_2_20].

• Upgrade: [Okio 3.16.0][okio_3_16_0].

Version 5.1.0
