NAME

6       bson_valgrind - Use Valgrind to Check For BSON Data Leaks
7
8       A  stack-allocated  bson_t  contains  a  small internal buffer; it only
9       heap-allocates additional storage if necessary, depending on  its  data
10       size. Therefore if you forget to call bson_destroy on a stack-allocated
11       bson_t, it might or might not cause a leak that can be detected by val‐
12       grind during testing.
13
14       To  catch  all  potential  BSON  data leaks in your code, configure the
15       BSON_MEMCHECK flag:
16
17          cmake -DCMAKE_C_FLAGS="-DBSON_MEMCHECK -g" .
18
19       With this flag set, every bson_t mallocs at least one  byte.  Run  your
20       program's  unittests with valgrind to verify all bson_t structs are de‐
21       stroyed.
22
23       Set the environment variable MONGOC_TEST_VALGRIND to on  to  skip  tim‐
24       ing-dependent tests known to fail with valgrind.
