# Allocation Recorder
The allocation_recorder lets Crashpad include a log of recent calls to malloc()
and free() when a memory safety fault is detected. Each entry includes a portion
of the stack trace as well as the size and the address of the object. The code
that generates the log lives in base/debug/allocation_trace.h
## Code organization
The component is split up into multiple parts.
- **crash_client**: To be used by the client, that is the process for which
a crash report shall be created. The client also contains the definition of
the recorder.
- **crash_handler**: To be used by the crashpad handler. In case of a crash, the
crash handler is responsible to create a proper report from the recorder data.
*This will be implemented in a follow up CL.*
- **internal**: Code that is shared between crash_client and crash_handler but
used only internally, i.e. name of the crashpad annotation used to store
data.
## Current state of implementation
Due to the size of implementation, the feature will be implemented in multiple
CLs.
| Nr | CL | Description |
| -- | -- | ----------- |
| 1 | https://chromium-review.googlesource.com/c/chromium/src/+/4323818 | **crash_client**: Introduce the crash client. The client should be fully implemented afterwards. |
