# Which Problems Are Solved
Panics may cause a service discruption by unexpectedly closing an
request's connection. Or in the case of gRPC completely killing the
service.
Allthough panics are still individual bugs that need to be solved, this
PR makes sure a panic is gracefully handled and an understandable error
is returned to the client.
# How the Problems Are Solved
- Recover in the middleware interceptors for the 3 API protocols (HTTP,
gRPC, connect).
- HTTP middleware uses formatted responses for:
- OIDC errors (JSON formatted response)
- UI (error page rendering)
- SCIM
- Upon recovery an alert level log is printed (ERROR+4 for stdlib log
handlers)

# Which Problems Are Solved
Group attributes weren't masked if their corresponding key was
configured. For example setting `data` as a masked key entry in the
runtime config would still print unmasked event data. This was because
ReplaceAttr does not receive group attributes, only the flattened
attributes with group information.
# How the Problems Are Solved
Check the current groups stack in the replacer. When a configured key is
found in the group, mask the current attribute. This means that the
attribute structure is preserved and all sub-keys of a masked group are
still printed.
# Additional Changes
- Use a binary search for key matching. As we are now comparing slice
against slice, a binary search should make the process a little faster
if many keys are configured.
# Additional Context
- Follow-up for PR #11435

# Which Problems Are Solved
Streams allow differentiating logs produced by different components of
Zitadel.
# How the Problems Are Solved
The `backend/v3/instrumentation/logging` package now exposes convenience
function for setting and getting a logger from the context. As well as
high-level functions to emit log records at various levels. When
constructing a new logger a "stream" needs to be specified:
- **runtime**: General runtime logs, such as startup and shutdown
messages. Default for logs that do not belong to the other categories.
- **request**: Logs for incoming API and HTTP requests.
- **event_handler**: Logs for event handling in projections.
- **queue**: Logs for the job queue processing.
- **event_pusher**: Logs for event pushing to the database. Disabled by
default, contains sensitive information.
Each line from the returned logger contains a `stream` field as well as
a `version` field with the current Zitadel version.
## Runtime config
Streams can be enabled by passing an array of stream names in the
runtime config. Because some log streams may contain sensitive data
(especially events), it is now also possible to mask values by their
key.
# Additional Changes
- Wrap `slogctx` in the `logging` package. (Except API error converter
packages, because of import cycle)
- Add some docs to `logging` package so other devs understand how to add
logging to Zitadel
- Add `logging.OnError` and `logging.WithError` helper functions with
`Panic()` and `Fatal()` methods, to preserve current calls in the `cmd`
packages.
- Add instance context extractor.
- Only output request details in the request info log. Request ID
remains propagated through context.
- Moved middleware functionality into protocol specific packages.
- Removed setting of URI to context in metric middleware. There were ony
setters and no getters. (Unused value)
- Reuse a single statusWriter in the middleware package for middlewares
that need to know the response status.
# Additional Context
- Closes#11333
- Closes#11331
- Partly #11330
