Disconnect3d	e5043535a3	Fix #1197: dont display ctx on reg/mem changes (#1239) ... * Fix #1197: dont display ctx on reg/mem changes This commit fixes a bug where we displayed context on registers or memory changes made by the user, so e.g. when user executed one of: ``` set *rax=1 set *(int*)0x<some address> = 0x1234 set *(unsigned long long*)$rsp+4=0x44444444 ``` It fixes it by just... setting a flag after the context is displayed for the first time and resetting it on a continue GDB event. There was a previous attempt to fix this bug in #1226 but it was rather a hack than a proper fix. This current commit should be a proper fix :P. Below is some more explanation of this bug. The fact that we displayed ctx on regs/mem changes was a result us clearing the cache of the `prompt_hook_on_stop` function: ```python @pwndbg.lib.memoize.reset_on_stop def prompt_hook_on_stop(*a): pwndbg.commands.context.context() ``` Where this function is called in `prompt_hook`, on each prompt display: ```python def prompt_hook(*a): global cur new = (gdb.selected_inferior(), gdb.selected_thread()) if cur != new: pwndbg.gdblib.events.after_reload(start=cur is None) cur = new if pwndbg.proc.alive and pwndbg.proc.thread_is_stopped: prompt_hook_on_stop(*a) ``` So, since we cleared this function cache on each register/memory changes, it resulted in us displaying context on each prompt hook. So how did we clear this function cache? Through the `memoize_on_stop` function: ``` @pwndbg.gdblib.events.stop @pwndbg.gdblib.events.mem_changed @pwndbg.gdblib.events.reg_changed def memoize_on_stop(): reset_on_stop._reset() ``` But why? We need this to make sure that all of the executed commands, when they read memory or registry, get proper new (not cached) values! So it makes sense to keep reseting the stop caches on mem/reg changed events. Otherwise, we would use incorrect (old) values if user set a register/memory and then used some commands like `context` or other that depend on register/memory state. * lint	3 years ago

disconnect3d	86e4679f79	add show-flags and show-compact-regs to ctx regs banner ... Hopefully his will improve the discoverability/UX for users who are not aware of those options. This is how the new registers banner looks like: ``` [ REGISTERS / show-flags off / show-compact-regs off ] ``` Fwiw it is 54 chars long (without "---" before and after) so its length should be fine.	3 years ago

disconnect3d	b209ada229	Fix disable_colors formatting & test ctx disasm showing fds ... This commit adds a test for context disasm showing of file descriptors file paths in syscalls like read() or close(). It also fixes a small issue when Pwndbg is run with PWNDBG_DISABLE_COLORS=1 This issue was that executing: ``` pi '{a:2}'.format(a=pwndbg.color.context.prefix(pwndbg.config.code_prefix)) ``` Failed when Pwndbg was run with disabled colors. It failed because our generate color functions in pwndbg/color/* ended up not processing the input argument -- which here is a Pwndbg config Paramater object -- so that we got a very non obvious exception: ``` Exception occurred: context: unsupported format string passed to Parameter.__format__ (<class 'TypeError'>) ``` This issue could hypothetically also exist if our config value would be empty I think. So with the fix in this commit, where we do str(x) over the color funciton argument should fix this issue in all cases.	3 years ago
