I wrote a plugin to load vmp trace file(10MB) and render corresponding instruction to red. The plugin code is below: from binaryninja import *
from binaryninja.log import log_warn, log_debug, log_info, log_error
from pathlib import Path
from time import sleep
import binaryninja.interaction as interaction
import binaryninja.filemetadata as filemetadata
import re
# 设置具体某个地址行的颜色
#current_function.set_user_instr_highlight(0x1236a, highlight.HighlightColor(red=0xff,blue=0,green=0))
tline="( libc.so[0xCBD52000])[08 B5 ]0xCBD602F8:0x0000e2f8: PUSH {R3, LR} ;(SP=0x100FEAA8 R3=0x00000000 LR=0x03000000 )"
def paint_trace(bv:BinaryView,function):
trace_filename= interaction.get_open_filename_input("Filename:")
if trace_filename is None:
print("No file specified")
sys.exit(1)
#
watch_so = Path(bv.file.filename).stem + ".so"
print("watch so " + watch_so)

# 在BN上调用这个插件会显示内存错误，关键就在于load这个文件的地方，可以用上面的链接来测试内存峰值
with open(trace_filename) as trace_file:
for line in trace_file:
if line[0] != '(':
continue
m = re.match(r'\( +([^\[]+)\[([^\[]+)\]\)\[([^\]]+)\]([^:]+):([^:]+).*',line)
so_name = m.groups()[0]
so_baseaddr = m.groups()[1]
inst = m.groups()[2]
inst_va = m.groups()[3]
inst_rva = m.groups()[4]
print(so_name + ", " + inst_rva)
break
if so_name != watch_so:
continue
bv.get_functions_containing(inst_rva)[0].set_user_instr_highlight(inst_rva, highlight.HighlightColor(red=0xff,blue=0,green=0))
#
PluginCommand.register_for_address("PaintTrace", "Color Trace Instruction", paint_trace)when i invoke it , the binary ninja crashed: it seems the OOM, after my debug, the script crash on iterate trace_file for line in trace_file:I write a demo python file test memory issue , open 10MB file , iterate line and print to stdout, test memory peakge according this link(https://stackoverflow.com/questions/12476804/how-i-can-get-the-peak-memory-on-mac-os/30124747#30124747):
