# Windows Integration overview
|
|
|
|
## Windows Client Code
|
|
|
|
The Windows client code is in the `src/client/windows` directory of the tree.
|
|
Since the header files are fairly well commented some specifics are purposely
|
|
omitted from this document.
|
|
|
|
## Integration of minidump-generation
|
|
|
|
Once you build the solution inside `src/client/windows`, an output file of
|
|
`exception_handler.lib` will be generated. You can either check this into your
|
|
project's directory or build directly from the source, as the project itself
|
|
does.
|
|
|
|
Enabling Breakpad in your application requires you to `#include
|
|
"exception_handler.h"` and instantiate the `ExceptionHandler` object like so:
|
|
|
|
```
|
|
handler = new ExceptionHandler(const wstring& dump_path,
|
|
FilterCallback filter,
|
|
MinidumpCallback callback,
|
|
void* callback_context,
|
|
int handler_types,
|
|
MINIDUMP_TYPE dump_type,
|
|
const wchar_t* pipe_name,
|
|
const CustomClientInfo* custom_info);
|
|
```
|
|
|
|
The parameters, in order, are:
|
|
|
|
* pathname for minidumps to be written to - this is ignored if OOP dump
|
|
generation is used
|
|
* A callback that is called when the exception is first handled - you can
|
|
return true/false here to continue/stop exception processing
|
|
* A callback that is called after minidumps have been written
|
|
* Context for the callbacks
|
|
* Which exceptions to handle - see `HandlerType` enumeration in
|
|
exception\_handler.h
|
|
* The type of minidump to generate, using the `MINIDUMP_TYPE` definitions in
|
|
`DbgHelp.h`
|
|
* A pipe name that can be used to communicate with a crash generation server
|
|
* A pointer to a CustomClientInfo class that can be used to send custom data
|
|
along with the minidump when using OOP generation
|
|
|
|
You can also see `src/client/windows/tests/crash_generation_app/*` for a sample
|
|
app that uses OOP generation.
|
|
|
|
## OOP Minidump Generation
|
|
|
|
For out of process minidump generation, more work is needed. If you look inside
|
|
`src/client/windows/crash_generation`, you will see a file called
|
|
`crash_generation_server.h`. This file is the interface for a crash generation
|
|
server, which must be instantiated with the same pipe name that is passed to the
|
|
client above. The logistics of running a separate process that instantiates the
|
|
crash generation server is left up to you, however.
|
|
|
|
## Build process specifics(symbol generation, upload)
|
|
|
|
The symbol creation step is talked about in the general overview doc, since it
|
|
doesn't vary much by platform. You'll need to make sure that the symbols are
|
|
available wherever minidumps are uploaded to for processing.
|
|
|
|
## Out in the field - uploading the minidump
|
|
|
|
Inside `src/client/windows/sender` is a class implementation called
|
|
`CrashReportSender`. This class can be compiled into a separate standalone CLI
|
|
or in the crash generation server and used to upload the report; it can know
|
|
when to do so via one of the callbacks provided by the `CrashGenerationServer`
|
|
or the `ExceptionHandler` object for in-process generation.
