If Sentry has access to application source code, it can show snippets of code around the location of stack frames. We refer to these snippets as source context. Source context can be very useful for quickly identify problematic code.
For example, here's a stack trace from a .NET application. The source context contains the original C# source code of the application, with the location of the frame highlighted.
Certain SDKs, such as the Python SDK, can resolve this source context automatically,
because they have access to unobfuscated source code at runtime.
By contrast, to get source context for compiled applications, the source code
needs to be uploaded alongside the debug information files.
The recommended way to do this is by using
See Creating Source Bundles for more information.
After they've been uploaded you can review and manage source bundles the same as
any other debug information file. See Managing Debug Information Files.
Source bundles will be tagged with
sources, and will carry the same filename as the
respective debug information file they were created from.
