xar_register_errhandler's usrctx gets set to NULL when a new error is raised #83
Description
What steps will reproduce the problem?
1. Register an error handler using xar_register_errhandler(x, callback,
some_custom_context)
2. xar_extract_tofile to a folder that is read only
3. the registered callback gets called with the error
What is the expected output? What do you see instead?
I'd expect the "some_custom_context" to be passed as the err_handler's usrctx
parameter, but I keep getting nil.
What version of the product are you using? On what operating system?
OS X Lion + XAR 1.5.2 from the Download's tarball.
Please provide any additional information below.
The issue happens because the usrctx is stored within the errctx struct and
when an error is reported xar_err_new is called which memsets errctx thus
removing the context. I would have expected the usrctx to be stored in the same
struct as the callback which would fix this issue.
I need this so that the error handler will call my ObjC wrapper.
