Refine copyright terms in GPL source files

2022-05-19T20:08:13+00:00

The GPL terms are copied from COPYING file.

* src/atomic_ops_malloc.c: Refine GPL copyright text in the header
comment by copying it as-is from COPYING file (as recommended in
"Apply These Terms to Your New Programs" section).
* src/atomic_ops_stack.c: Likewise.
* tests/list_atomic.template: Likewise.
* tests/run_parallel.h: Likewise.
* tests/test_atomic.c: Likewise.
* tests/test_atomic_include.template: Likewise.
* tests/test_malloc.c: Likewise.
* tests/test_stack.c: Likewise.
* tests/test_atomic_include.h: Regenerate.

Avoid breaking strict-aliasing rules in cons() of test_malloc

2022-02-17T19:07:15+00:00

* tests/test_malloc.c (cons): Change type of extras local variable from
int* to char*; set every sizeof(int) byte of extras[] to 42 (instead of
setting every int value).

Workaround 'argument to function assert is always 1' cppcheck warnings

2018-12-19T09:12:34+00:00

* src/atomic_ops_malloc.c (get_chunk): Skip assertion about
my_chunk_ptr value alignment if CPPCHECK.
* tests/test_malloc.c (DEFAULT_NTHREADS): Add comment about the
maximum value.
* tests/test_malloc.c (main): Remove assertion of nthreads value which
is set to DEFAULT_NTHREADS (ideally there should be a static_assert).
* tests/test_stack.c (main): Likewise.

Convert tests to valid C++ code

2018-02-08T22:12:27+00:00

* tests/test_malloc.c (cons, dummy_test, run_one_test): Add explicit
cast of void* pointer (returned by malloc) to the type of the variable
the pointer is assigned to.
* tests/test_stack.c (add_elements): Likewise.

Fill in allocated memory with values depending on thread id (test_malloc)

2017-12-20T07:31:07+00:00

* tests/test_malloc.c (run_one_test): Define new local variables a, b
(with the values depending on arg); replace 'a' and 'b' with a and b,
respectively; reformat the code; return NULL instead of arg; remove
the comment (the workaround is no longer needed).

Do not test CHUNK_SIZE allocation if no mmap() available (test_malloc)

2017-12-19T09:05:01+00:00

(fix commit 29d91db)

* tests/test_malloc.c (main): Do not call AO_malloc(CHUNK_SIZE) unless
HAVE_MMAP.

New macro (DONT_USE_MMAP) to support testing as if mmap() is unavailable

2017-12-19T08:19:44+00:00

* src/atomic_ops_malloc.c [DONT_USE_MMAP] (HAVE_MMAP): Undefine (after
including config.h).
* tests/test_malloc.c [DONT_USE_MMAP] (HAVE_MMAP): Likewise.

Increase the default number of threads to 16 in test_malloc/stack

2017-12-06T21:39:04+00:00

* tests/test_malloc.c [!DEFAULT_NTHREADS && HAVE_MMAP]
(DEFAULT_NTHREADS): Change the value from 10 to 16.
* tests/test_stack.c [!DEFAULT_NTHREADS] (DEFAULT_NTHREADS): Change
the value from 4 to 16.

Allow to alter DEFAULT/MAX_NTHREADS values in test_malloc/stack

2017-12-06T21:22:41+00:00

(code refactoring)

* tests/run_parallel.h [!MAX_NTHREADS] (MAX_NTHREADS): Define (move
from test_malloc.c).
* tests/run_parallel.h [USE_PTHREADS || USE_VXTHREADS
|| USE_WINTHREADS] (run_parallel): Replace 100 with MAX_NTHREADS.
* tests/test_malloc.c (main): Add assertion that DEFAULT_NTHREADS
is not greater than MAX_NTHREADS.
* tests/test_stack.c (main): Likewise.
* tests/test_stack.c [!DEFAULT_NTHREADS] (DEFAULT_NTHREADS): Define
(to 4).
* tests/test_stack.c (main): Use DEFAULT_NTHREADS (instead of 4).

Test smallest allocation of large type (test_malloc)

2017-12-04T21:08:40+00:00

* src/atomic_ops_malloc.c (AO_malloc_large): Add assertion that the
stored size is greater than LOG_MAX_SIZE.
* src/atomic_ops_malloc.c (AO_malloc): Add assertions for log_size.
* tests/test_malloc.c (LOG_MAX_SIZE, CHUNK_SIZE): New macro (copied
from atomic_ops_malloc.c).
* tests/test_malloc.c (main): Call AO_free(0), AO_malloc(0),
AO_malloc(CHUNK_SIZE-sizeof(AO_t)+1); add comment.
