okhttp v2.5.0 Release Notes

  • 2015-08-25

    • Timeouts now default to 10 seconds. Previously we defaulted to never timing out, and that was a lousy policy. If establishing a connection, reading the next byte from a connection, or writing the next byte to a connection takes more than 10 seconds to complete, you’ll need to adjust the timeouts manually.

    • OkHttp now rejects request headers that contain invalid characters. This includes potential security problems (newline characters) as well as simple non-ASCII characters (including international characters and emoji).

    • Call canceling is more reliable. We had a bug where a socket being connected wasn't being closed when the application used Call.cancel().

    • Changing a HttpUrl’s scheme now tracks the default port. We had a bug where changing a URL from http to https would leave it on port 80.

    • Okio has been updated to 1.6.0.

       <dependency>
   <groupId>com.squareup.okio</groupId>
   <artifactId>okio</artifactId>
   <version>1.6.0</version>
 </dependency>

    • New: Cache.initialize(). Call this on a background thread to eagerly initialize the response cache.

    • New: Fold MockWebServerRule into MockWebServer. This makes it easier to write JUnit tests with MockWebServer. The MockWebServer library now depends on JUnit, though it continues to work with all testing frameworks.

    • Fix: FormEncodingBuilder is now consistent with browsers in which characters it escapes. Previously we weren’t percent-encoding commas, parens, and other characters.

    • Fix: Relax FormEncodingBuilder to support building empty forms.

    • Fix: Timeouts throw SocketTimeoutException, not InterruptedIOException.

    • Fix: Change MockWebServer to use the same logic as OkHttp when determining whether an HTTP request permits a body.

    • Fix: HttpUrl now uses the canonical form for IPv6 addresses.

    • Fix: Use HttpUrl internally.

    • Fix: Recover from Android 4.2.2 EBADF crashes.

    • Fix: Don't crash with an IllegalStateException if an HTTP/2 or SPDY write fails, leaving the connection in an inconsistent state.

    • Fix: Make sure the default user agent is ASCII.
