Sylar Nerwork Server Study Code

Sylar Network Server Study Code

Introduction

A Repo with sylar network server study codes, including self-optimized codes.

Versions

• KUbuntu 20.04
• gcc 9.4.0 x86_64-linux-gnu
• cmake 3.16.3

External Dependencies

• libbacktrace and libdl (if enabled "Debug" or "RelWithDebInfo")

  libbacktrace and libdl are a linux built-in libraries.

  Note: libdl should be linked whenever boost::stacktrace is used with gcc

  It is used and linked by libsylar while

  • "Debug" or "RelWithDebInfo" is configured
  • USE_BOOST_BACKTRACE=ON

  If not compiled with debug info, we use c api ::backtrace and ::backtrace_symbol to get backtrace info.

  If we use c api ::backtrace and ::backtrace_symbol, we get things like:

  2023-02-13 17:59:54 [ERROR][root](t:146705)(f:0) tests/test_util.cc:11  ASSERTION: false
  backtrace:
   -- 0# bin/test_util(+0x2f93) [0x55f682682f93]
   -- 1# bin/test_util(+0x273f) [0x55f68268273f]
   -- 2# /lib/x86_64-linux-gnu/libc.so.6(__libc_start_main+0xf3) [0x7f781e0c5083]
   -- 3# bin/test_util(+0x29be) [0x55f6826829be]
  

  But if we use boost::stacktrace and libbacktrace, we can get prettier and more readable backtrace as following:

  2023-02-13 18:01:46 [ERROR][root](t:146991)(f:0) tests/test_util.cc:11  ASSERTION: false
  backtrace:
   -- 0# test_assert() at /home/windsgo/Documents/codes/SylarServerStudy/tests/test_util.cc:11
   -- 1# main at /home/windsgo/Documents/codes/SylarServerStudy/tests/test_util.cc:23
   -- 2# __libc_start_main at ../csu/libc-start.c:342
   -- 3# _start in bin/test_util
