/* TODO list:
|
|
*
|
|
* - minidump
|
|
* + ensure that all commands work as expected in minidump reload function
|
|
* (and reenable parser usager)
|
|
* - CPU adherence
|
|
* + we always assume the stack grows as on i386 (ie downwards)
|
|
* - UI
|
|
* + enable back the limited output (depth of structure printing and number of
|
|
* lines)
|
|
* + make the output as close as possible to what gdb does
|
|
* - symbol management:
|
|
* + symbol table loading is broken
|
|
* + in symbol_get_lvalue, we don't do any scoping (as C does) between local and
|
|
* global vars (we may need this to force some display for example). A solution
|
|
* would be always to return arrays with: local vars, global vars, thunks
|
|
* - type management:
|
|
* + some bits of internal types are missing (like type casts and the address
|
|
* operator)
|
|
* + the type for an enum's value is always inferred as int (winedbg & dbghelp)
|
|
* + most of the code implies that sizeof(void*) = sizeof(int)
|
|
* + all computations should be made on long long
|
|
* o expr computations are in int:s
|
|
* o bitfield size is on a 4-bytes
|
|
* - execution:
|
|
* + set a better fix for gdb (proxy mode) than the step-mode hack
|
|
* + implement function call in debuggee
|
|
* + trampoline management is broken when getting 16 <=> 32 thunk destination
|
|
* address
|
|
* + thunking of delayed imports doesn't work as expected (ie, when stepping,
|
|
* it currently stops at first insn with line number during the library
|
|
* loading). We should identify this (__wine_delay_import) and set a
|
|
* breakpoint instead of single stepping the library loading.
|
|
* + it's wrong to copy thread->step_over_bp into process->bp[0] (when
|
|
* we have a multi-thread debuggee). complete fix must include storing all
|
|
* thread's step-over bp in process-wide bp array, and not to handle bp
|
|
* when we have the wrong thread running into that bp
|
|
* + code in CREATE_PROCESS debug event doesn't work on Windows, as we cannot
|
|
* get the name of the main module this way. We should rewrite all this code
|
|
* and store in struct dbg_process as early as possible (before process
|
|
* creation or attachment), the name of the main module
|
|
* - global:
|
|
* + define a better way to enable the wine extensions (either DBG SDK function
|
|
* in dbghelp, or TLS variable, or environment variable or ...)
|
|
* + audit all files to ensure that we check all potential return values from
|
|
* every function call to catch the errors
|
|
* + BTW check also whether the exception mechanism is the best way to return
|
|
* errors (or find a proper fix for MinGW port)
