通过Valgrind检查泄漏时阻止某些功能

Question

在我的程序中，我使用的是GNU Readline，该库中的功能会导致一些泄漏。在使用Valgrind时，我不想看到这些泄漏。我可以以某种方式阻止一些功能吗？

Answer 1

我从使用valgrind-leak-check = full -show-show-leak-kinds = all ./program

==2376== 28,784 bytes in 7 blocks are still reachable in loss record 57 of 57
==2376==    at 0x483B7F3: malloc (in /usr/lib/x86_64-linux-gnu/valgrind/vgpreload_memcheck-amd64-linux.so)
==2376==    by 0x489500C: xmalloc (in /usr/lib/x86_64-linux-gnu/libreadline.so.8.0)
==2376==    by 0x4873A91: rl_make_bare_keymap (in /usr/lib/x86_64-linux-gnu/libreadline.so.8.0)
==2376==    by 0x487AD79: rl_generic_bind (in /usr/lib/x86_64-linux-gnu/libreadline.so.8.0)
==2376==    by 0x487CA92: rl_parse_and_bind (in /usr/lib/x86_64-linux-gnu/libreadline.so.8.0)
==2376==    by 0x487CC6C: ??? (in /usr/lib/x86_64-linux-gnu/libreadline.so.8.0)
==2376==    by 0x486F228: rl_initialize (in /usr/lib/x86_64-linux-gnu/libreadline.so.8.0)
==2376==    by 0x486F4AF: readline (in /usr/lib/x86_64-linux-gnu/libreadline.so.8.0)
==2376==    by 0x10B6B5: main (main.c:77)

我制作了一个名为supp.supp并在其中写了：

{
    ignore_libreadline_leaks
    Memcheck:Leak
    ...
    obj:*/libreadline.so.*
}

之后，我添加了- 抑制= supp.supp flag。现在抑制了Libreadline的所有泄漏错误。
