20 /* Debugging hooks for malloc. */
|
|
|
21
|
|
|
22 /* These hooks work with gmalloc to catch allocation errors.
|
|
|
23 In particular, the following is trapped:
|
|
|
24
|
|
|
25 * Freeing the same pointer twice.
|
|
|
26 * Trying to free a pointer not returned by malloc.
|
|
|
27 * Trying to realloc a pointer not returned by malloc.
|
|
|
28
|
|
|
29 In addition, every word of every block freed is set to
|
|
|
30 0xdeadbeef. This causes many uses of freed storage to be
|
|
|
31 trapped or recognized.
|
|
|
32
|
|
|
33 When you use this, the storage used by the last FREE_QUEUE_LIMIT
|
|
|
34 calls to free() is not recycled. When you call free for the Nth
|
|
|
35 time, the (N - FREE_QUEUE_LIMIT)'th block is actually recycled.
|
|
|
36
|
|
|
37 For these last FREE_QUEUE_LIMIT calls to free() a backtrace is
|
|
|
38 saved showing where it was called from. The function
|
|
|
39 find_backtrace() is provided here to be called from GDB with a
|
|
|
40 pointer (such as would be passed to free()) as argument, e.g.
|
|
|
41 (gdb) p/a *find_backtrace (0x234000). If SAVE_ARGS is defined,
|
|
|
42 the first three arguments to each function are saved as well as the
|
|
|
43 return addresses.
|
|
|
44
|
|
|
45 If UNMAPPED_FREE is defined, instead of setting every word of freed
|
|
|
46 storage to 0xdeadbeef, every call to malloc goes on its own page(s).
|
|
|
47 When free() is called, the block is read and write protected. This
|
|
|
48 is very useful when debugging, since it usually generates a bus error
|
|
|
49 when the deadbeef hack might only cause some garbage to be printed.
|
|
|
50 However, this is too slow for everyday use, since it takes an enormous
|
|
|
51 number of pages.
|
|
|
52
|
|
|
53
|
|
|
54 Some other features that would be useful are:
|
|
|
55
|
|
|
56 * Checking for storage leaks.
|
|
|
57 This could be done by a GC-like facility that would scan the data
|
|
|
58 segment looking for pointers to allocated storage and tell you
|
|
|
59 about those that are no longer referenced. This could be invoked
|
|
|
60 at any time. Another possibility is to report on what allocated
|
|
|
61 storage is still in use when the process is exited. Typically
|
|
|
62 there will be a large amount, so this might not be very useful.
