# Changelog

## 0.6.0

**Breaking changes**:

- When built as a shared library for Android or Linux, the Native SDK limits the export of symbols to the `sentry_`-prefix. The option `SENTRY_EXPORT_SYMBOLS` is no longer available and the linker settings are constrained to the Native SDK and no longer `PUBLIC` to parent projects. ([#363](https://github.com/getsentry/sentry-native/pull/363))

**Features**:

- A session may be ended with a different status code. ([#801](https://github.com/getsentry/sentry-native/pull/801))

**Fixes**:

- Switch Crashpad transport on Linux to use libcurl ([#803](https://github.com/getsentry/sentry-native/pull/803), [crashpad#75](https://github.com/getsentry/crashpad/pull/75), [crashpad#79](https://github.com/getsentry/crashpad/pull/79))
- Avoid accidentally mutating CONTEXT when client-side stack walking in Crashpad ([#803](https://github.com/getsentry/sentry-native/pull/803), [crashpad#77](https://github.com/getsentry/crashpad/pull/77))
- Fix various mingw compilation issues ([#794](https://github.com/getsentry/sentry-native/pull/794), [crashpad#78](https://github.com/getsentry/crashpad/pull/78))

- Added a CI timeout for the Android simulator start. ([#764](https://github.com/getsentry/sentry-native/pull/764))

## 0.5.0

**Features**:

- Provide `on_crash()` callback to allow clients to act on detected crashes.
  Users often inquired about distinguishing between crashes and "normal" events in the `before_send()` hook. `on_crash()` can be considered a replacement for `before_send()` for crash events, where the goal is to use `before_send()` only for normal events, while `on_crash()` is only invoked for crashes. This change is backward compatible for current users of `before_send()` and allows gradual migration to `on_crash()` ([see the docs for details](https://docs.sentry.io/platforms/native/configuration/filtering/)). ([#724](https://github.com/getsentry/sentry-native/pull/724), [#734](https://github.com/getsentry/sentry-native/pull/734))

**Fixes**:

- Make Windows ModuleFinder more resilient to missing Debug Info ([#732](https://github.com/getsentry/sentry-native/pull/732))
- Aligned pre-send event processing in `sentry_capture_event()` with the [cross-SDK session filter order](https://develop.sentry.dev/sdk/sessions/#filter-order) ([#729](https://github.com/getsentry/sentry-native/pull/729))
- Align the default value initialization for the `environment` payload attribute with the [developer documentation](https://develop.sentry.dev/sdk/event-payloads/#optional-attribute) ([#739](https://github.com/getsentry/sentry-native/pull/739))
- Iterate all debug directory entries when parsing PE modules for a valid CodeView record ([#740](https://github.com/getsentry/sentry-native/pull/740))

## 0.4.18

**Features**:

- The crashpad backend now captures thread names. ([#725](https://github.com/getsentry/sentry-native/pull/725))
- The inproc backend now captures the context registers. ([#714](https://github.com/getsentry/sentry-native/pull/714))
- A new set of APIs to get the sentry SDK version at runtime. ([#726](https://github.com/getsentry/sentry-native/pull/726))
- Add more convenient APIs to attach stack traces to exception or thread values. ([#723](https://github.com/getsentry/sentry-native/pull/723))
- Allow disabling the crash reporting backend at runtime. ([#717](https://github.com/getsentry/sentry-native/pull/717))

**Fixes**:

- Improved heuristics flagging sessions as "crashed". ([#719](https://github.com/getsentry/sentry-native/pull/719))

**Internal**:

- Updated Breakpad and Crashpad backends to 2022-06-14. ([#725](https://github.com/getsentry/sentry-native/pull/725))

## 0.4.17

**Fixes**:

- sentry-native now successfully builds when examples aren't included. ([#702](https://github.com/getsentry/sentry-native/pull/702))

**Thank you**:

Features, fixes and improvements in this release have been contributed by:

- [@AenBleidd](https://github.com/AenBleidd)

## 0.4.16

**Features**:

- Removed the `SENTRY_PERFORMANCE_MONITORING` compile flag requirement to access performance monitoring in the Sentry SDK. Performance monitoring is now available to everybody who has opted into the experimental API.
- New API to check whether the application has crashed in the previous run: `sentry_get_crashed_last_run()` and `sentry_clear_crashed_last_run()` ([#685](https://github.com/getsentry/sentry-native/pull/685)).
- Allow overriding the SDK name at build time - set the `SENTRY_SDK_NAME` CMake cache variable.
- More aggressively prune the Crashpad database. ([#698](https://github.com/getsentry/sentry-native/pull/698))

**Internal**:

- Project IDs are now treated as opaque strings instead of integer values. ([#690](https://github.com/getsentry/sentry-native/pull/690))
- Updated Breakpad and Crashpad backends to 2022-04-12. ([#696](https://github.com/getsentry/sentry-native/pull/696))

**Fixes**:

## 0.4.15

**Fixes**:

- Fix contexts from the scope not being attached to events correctly.
- Improve performance of event serialization.

## 0.4.14

**Features**:

- The Sentry SDK now has experimental support for performance monitoring.
  The performance monitoring API allows manually creating transactions and instrumenting spans, and offers APIs for distributed tracing.
  The API is currently disabled by default and needs to be enabled via a compile-time `SENTRY_PERFORMANCE_MONITORING` flag.
  For more information, take a look at the more detailed [documentation of performance monitoring](https://docs.sentry.io/platforms/native/performance/).
- Sentry now has an explicit `sentry_flush` method that blocks the calling thread for the given time, waiting for the transport queue to be flushed. Custom transports need to implement a new `flush_hook` for this to work.

**Fixes**:

- Fix Sentry API deadlocking when the SDK was not initialized (or `sentry_init` failed).
- The rate limit handling of the default transports was updated to match the expected behavior.
- The Windows OS version is now read from the Registry and is more accurate.
- The `SENTRY_LIBRARY_TYPE` CMake option is now correctly honored.
- The Linux Modulefinder was once again improved to increase its memory safety and reliability.

## 0.4.9

**Features**:

- Rewrote the Linux modulefinder which should now work correctly when encountering gaps in the memory mapping of loaded libraries, and supports libraries loaded from a file offset, such as libraries loaded directly from `.apk` files on Android.
- Invoke the `before_send` hook at time of a hard crash when using the Windows or Linux Crashpad backend.
- Added the following new convenience functions:
  - `sentry_value_new_exception`

  - `sentry_value_new_stacktrace`
  - `sentry_event_add_exception`
  - `sentry_event_add_thread`
  - The `sentry_event_value_add_stacktrace` is deprecated.

## 0.4.3

**Caution**:

- The representation of `sentry_value_t` was changed to avoid problems with the newly introduced Memory Tagging Extension (MTE) on ARM / Android.
  Implementation details of `sentry_value_t` were never considered public, and it should always be treated as an opaque type.

## 0.4.2

**Fixes**:

- Sampled (discarded) events still contribute to a sessions `errors` count.
- Initialize all static data structures.

## 0.4.1

**Fixes**:

- Fix parsing rate limit headers with multiple categories.

## 0.4.0

**Breaking Changes**:

- The minimum CMake version required to build on windows was raised to `3.16.4` to avoid potential build failures on older versions.
- The `sentry_get_options` function was removed, as it was unsafe to use after a `sentry_shutdown` call.
- The `sentry_options_set_logger` function now accepts a `userdata` parameter.
- The `name` parameter of `sentry_options_add_attachment(w)` was removed, it will now be inferred from the filename of `path`.
- The transport startup hook that is set via `sentry_transport_set_startup_func` now needs to return an `int`, and a failure will propagate to `sentry_init`.
- The return value of the transport shutdown hook set via `sentry_transport_set_shutdown_func` was also changed to return an `int`.
- Both functions should return _0_ on success, and a non-zero error code on failure, as does `sentry_init`.
- Similarly, the return value of `sentry_shutdown` was also changed to an `int`, and will return _0_ on success and a non-zero error code on unclean shutdown.
- Documentation for custom transports was updated to highlight the ordering requirements of submitted envelopes, which is important for release health.

```c
// before
sentry_options_set_logger(options, my_custom_logger);
sentry_options_add_attachment(options, "some-attachment", "/path/to/some-attachment.txt");

void transport_startup(sentry_options_t *options, void*state) {
}
sentry_transport_set_startup_func(transport, transport_startup);
bool transport_shutdown(uint64_t timeout, void*state) {
  return true;
}
sentry_transport_set_shutdown_func(transport, transport_shutdown);

// after
sentry_options_set_logger(options, my_custom_logger, NULL);
sentry_options_add_attachment(options, "/path/to/some-attachment.txt");

int transport_startup(sentry_options_t *options, void*state) {
  return 0;
}
sentry_transport_set_startup_func(transport, transport_startup);
int transport_shutdown(uint64_t timeout, void*state) {
  return 0;
}
sentry_transport_set_shutdown_func(transport, transport_shutdown);
```

**Features**:

- [Release Health](https://docs.sentry.io/workflow/releases/health/) support is now stable and enabled by default. After the update, you will see the number of crash free sessions and crash free users on the Releases page in Sentry. To disable automatic session tracking, use `sentry_options_set_auto_session_tracking`.
- Breakpad support for Windows. This allows you to use `sentry-native` even on Windows XP! ([#278](https://github.com/getsentry/sentry-native/pull/278))
- Add an in-process backend for Windows. As opposed to Breakpad, stack traces are generated on the device and sent to Sentry for symbolication. ([#287](https://github.com/getsentry/sentry-native/pull/287))
- Support for the Crashpad backend was fixed and enabled for Linux. ([#320](https://github.com/getsentry/sentry-native/pull/320))
- A new `SENTRY_BREAKPAD_SYSTEM` CMake option was added to link to the system-installed breakpad client instead of building it as part of sentry.

**Fixes**:

- Reworked thread synchronization code and logic in `sentry_shutdown`, avoiding an abort in case of an unclean shutdown. ([#323](https://github.com/getsentry/sentry-native/pull/323))
- Similarly, reworked global options handling, avoiding thread safety issues. ([#333](https://github.com/getsentry/sentry-native/pull/333))
- Fixed errors not being properly recorded in sessions. ([#317](https://github.com/getsentry/sentry-native/pull/317))
- Fixed some potential memory leaks and other issues. ([#304](https://github.com/getsentry/sentry-native/pull/304) and others)

## 0.3.4

**Fixes**:

- Invalid memory access when `sentry_options_set_debug(1)` is set, leading to an application crash. This bug was introduced in version `0.3.3`. ([#310](https://github.com/getsentry/sentry-native/pull/310)).

## 0.3.3

**Fixes**:

- Fix a memory unsafety issue when calling `sentry_value_remove_by_key`. ([#297](https://github.com/getsentry/sentry-native/pull/297))
- Improvements to internal logging. ([#301](https://github.com/getsentry/sentry-native/pull/301), [#302](https://github.com/getsentry/sentry-native/pull/302))
- Better handling of timeouts. ([#284](https://github.com/getsentry/sentry-native/pull/284))

- [@eakoli](https://github.com/eakoli)

## 0.3.2

**Features**:

- Implement a new logger hook. ([#267](https://github.com/getsentry/sentry-native/pull/267))

  This adds the new `sentry_options_set_logger` function, which can be used to customize the sentry-internal logging, for example to integrate into an app’s own logging system, or to stream logs to a file.

- New CMake options: `SENTRY_LINK_PTHREAD`, `SENTRY_BUILD_RUNTIMESTATIC` and `SENTRY_EXPORT_SYMBOLS` along with other CMake improvements.

**Fixes**:

- Avoid memory unsafety when loading session from disk. ([#270](https://github.com/getsentry/sentry-native/pull/270))
- Avoid Errors in Crashpad Backend without prior scope changes. ([#272](https://github.com/getsentry/sentry-native/pull/272))
- Fix absolute paths on Windows, and allow using forward-slashes as directory separators. ([#266](https://github.com/getsentry/sentry-native/pull/266), [#289](https://github.com/getsentry/sentry-native/pull/289))
- Various fixes uncovered by static analysis tools, notably excessive allocations by the page-allocator used inside signal handlers.
- Build fixes for MinGW and other compilers.

## 0.3.1

- Add support for on-device symbolication, which is enabled by default on
  Android. Use `sentry_options_set_symbolize_stacktraces` to customize.
- Enable gzip compressed crashpad minidumps on windows.
- Correctly 0-pad short `build-id`s.
- Fix build for 32bit Apple targets.

## 0.3.0

- Always send the newer `x-sentry-envelope` format, which makes this
  incompatible with older on-premise installations.
- Better document and handle non-ASCII paths. Users on windows should use the
  `w` version of the appropriate APIs.
- Avoid segfaults due to failed sentry initialization.
- Avoid creating invalid sessions without a `release`.
- Make `sentry_transport_t` opaque, and instead expose APIs to configure it.
  More functionality related to creating custom transports will be exposed in
  future versions.

### Breaking changes

- The `sentry_backend_free` function was removed.
- The `sentry_backend_t` type was removed.
- The `sentry_transport_t` type is now opaque. Use the following new API to
  create a custom transport.

### New API

- `sentry_transport_new`
- `sentry_transport_set_state`
- `sentry_transport_set_free_func`
- `sentry_transport_set_startup_func`
- `sentry_transport_set_shutdown_func`

See `sentry.h` for more documentation.

### Deprecations

- `sentry_new_function_transport` has been deprecated in favor of the new
  transport builder functions.

## 0.2.6

- Avoid crash with invalid crashpad handler path.

## 0.2.5

- Send sessions to the correct sentry endpoint and make sure they work.
- Smaller cleanups.

## 0.2.4

- Avoid unsafe reads in the linux module finder.
- Update to latest crashpad snapshot.
- Yet more CMake improvements (thanks @madebr and @Amphaal).

## 0.2.3

### Important upgrade notice

All `0.2.x` versions prior to this one were affected by a bug that could
potentially lead to serious data-loss on Windows platforms. We encourage
everyone to update as quickly as possible.
See [#220](https://github.com/getsentry/sentry-native/issues/220) for details.

### Deprecations

- `sentry_transport_t` will be replaced by an opaque struct with setter methods
  in a future release.
- `sentry_backend_free` and `sentry_backend_t` are deprecated and will be
  removed in a future release.

### Other changes

- Further improvements to the cmake build system (huge thanks to @madebr
  [#207](https://github.com/getsentry/sentry-native/pull/207))
- Improved support for older Windows versions, as low as Windows XP SP3 (thanks
  to @Mixaill [#203](https://github.com/getsentry/sentry-native/pull/203),
  @cammm [#202](https://github.com/getsentry/sentry-native/pull/202) and
  @jblazquez [#212](https://github.com/getsentry/sentry-native/pull/212))
- Improved documentation
- Cleaned up sentry database handling
- Added new `sentry_handle_exception` function to explicitly capture a crash
  (thanks @cammm [#201](https://github.com/getsentry/sentry-native/pull/201))
- Added new `sentry_clear_modulecache` function to clear the list of loaded
  modules. Use this function when dynamically loading libraries at runtime.

## 0.2.2

- Implement experimental Session handling
- Implement more fine grained Rate Limiting for HTTP requests
- Implement `sample_rate` option
- In-process and Breakpad backend will not lose events queued for HTTP
  submission on crash
- `sentry_shutdown` will better clean up after itself
- Add Experimental MinGW build support (thanks @Amphaal
  [#189](https://github.com/getsentry/sentry-native/pull/189))
- Various other fixes and improvements

## 0.2.1

- Added Breakpad support on Linux
- Implemented fallback `debug-id` on Linux and Android for modules that are
  built without a `build-id`
- Fixes issues and added CI for more platforms/compilers, including 32-bit Linux
  and 32-bit VS2017
- Further improvements to the CMake configuration (thanks @madebr
  [#168](https://github.com/getsentry/sentry-native/pull/168))
- Added a new `SENTRY_TRANSPORT` CMake option to customize the default HTTP transport

## 0.2.0

- Complete rewrite in C
- Build system was switched to CMake
- Add attachment support
- Better support for custom transports
- The crashpad backend will automatically look for a `crashpad_handler`
  executable next to the running program if no `handler_path` is set.

### Breaking Changes

- The `sentry_uuid_t` struct is now always a `char bytes[16]` instead of a
  platform specific type.
- `sentry_remove_context`: The second parameter was removed.
- `sentry_options_set_transport`:
  This function now takes a pointer to the new `sentry_transport_t` type.
  Migrating from the old API can be done by wrapping with
  `sentry_new_function_transport`, like this:

  ```c
  sentry_options_set_transport(
        options, sentry_new_function_transport(send_envelope_func, &closure_data));
  ```

### Other API Additions

- `size_t sentry_value_refcount(sentry_value_t value)`
- `void sentry_envelope_free(sentry_envelope_t *envelope)`
- `void sentry_backend_free(sentry_backend_t *backend)`
