[issue22534] Possible Memory Leak with 'shelve'

[TJ]

TJ added the comment:

Thanks for the help. For my linux box, I have no issue. This is Ubuntu 13.10:

    Linux localhost 3.11.0-26-generic #45-Ubuntu SMP Tue Jul 15 04:02:06 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux

    2.7.5+ (default, Feb 27 2014, 19:37:08) 
    [GCC 4.8.1]

However, I'm still getting issues with my other box, which is Mac OS. I think I have the relevant info here (let me know if we need additional info):

    [10:55:00] ~$ sw_vers -productVersion
    10.9.2

    [10:55:10] ~$ python -c "import sys; print sys.version"
    2.7.8 (default, Aug 21 2014, 20:13:48) 
    [GCC 4.2.1 Compatible Apple LLVM 5.1 (clang-503.0.40)]

    [10:55:57] ~$ python -c "import anydbm;d = anydbm.open('bla', 'c');print(type(d))"
    <class 'bsddb._DBWithCursor'>

    [10:56:05] ~$ cat leaktest.py
    import anydbm
    while True:
        d = anydbm.open('bla', 'c')
        d.close()

    [10:56:10] ~$ python leaktest.py &
    [1] 99030

    [10:56:18] ~$ ps -o pid,rss,vsz,command -p 99030
      PID    RSS      VSZ COMMAND
    99030 481928  3010600 python leaktest.py

    [10:56:56] ~$ ps -o pid,rss,vsz,command -p 99030
      PID    RSS      VSZ COMMAND
    99030 3985920  6516788 python leaktest.py

    [11:01:10] ~$ # After 5 minutes, "top" shows MEM as 13G

    [11:01:23] ~$ ps -o pid,rss,vsz,command -p 99030
      PID    RSS      VSZ COMMAND
    99030 13891152 16429156 python leaktest.py

Those numbers are stable on my Linux box, and ever growing on Mac.
