Master & Relay Log info files read 2^31 and above incorrectly

    XMLWordPrintable

Details

    • Can result in unexpected behaviour

    Description

      @@master_info_file and @@relay_log_info_file read integers (including IDs in lists) with atoi, which can only read signed 32-bits.
      However, the integer fields in those files are unsigned fields, which has a higher maximum. Some of them 64-bit, too.

      To demonstrate, the attached MTR test shows 2147483648 (0x8000'0000) gets reloaded as 18446744071562067968 (0xffff'ffff'8000'0000).
      P.S. Nevermind the LP64 requirement in that test.
