gnu.cfg: Add xfree() (#2051)
It is hard to find good references, one that describes it a bit can
be found here:
https://manpages.ubuntu.com/manpages/bionic/man3/xmalloc.3pub.html

xfree() can be used instead of free().
A check, to verify that a memory leak is found if the memory allocated
via xmalloc() is not freed, has also been added.

Rikard Falkeborn 8cd1d5a47d Use library for memleak checks (#2002)
* Use library for memleak checks

Change memleakOnRealloc and leakReturnValNotUsed to use library
configuration instead of hardcoding "realloc".

In order to do so, some care needs to be taken when matching for a
reallocation function, since it can no longer be assumed that the input
to be allocated is the first argument of the function. This complicates
getReallocationType() and checkReallocUsage() but is necessary in order
to handle for example freopen() properly.

Also, refactor memleakOnRealloc check to reduce duplicated code when
checking "a" and "*a". When doing so, extending the check to look for
arbitrary number of "*" can be done for free (just change an if
statement to a while statement). Most likely, this is an unusual case in
real world code.

* Remove redundant whitespace in Token::Match()

* Run on simplified checks

* Fix cppcheck warning

was no error.

Rikard Falkeborn dcc375ca64 Update gtk memory functions (#2000)
* Improve configuration of g_try_realloc and g_try_realloc_n
* Mark g_realloc and similar functions as realloc functions
* Remove g_new, g_new0, etc as <alloc> functions, these are defined as
  macros and handled as the functions they're expanded to.
* Add tests. TODO tests will be resolved by using the library
  configuration in the checker.

posix.cfg: Add `<use-retval/>` to pthread_mutex_trylock (#1959)
Ignoring the return value of pthread_mutex_trylock is always a bug.
There is no other way to check if the mutex is locked or not after the
call.

Rikard Falkeborn 2bd026dd2a Add tests of std.cfg buffer size (#1958)
Includes a testcase for trac ticket #1379 which was fixed in
839fcddd8a.
2019-07-06 08:55:17 +02:00
Rikard Falkeborn 839fcddd8a Fix #6115 (Add support to realloc to cfg files) (#1953)
* Allow to configure realloc like functions

* memleakonrealloc: Bring back tests.

The old memleak checker was removed, and the tests for it was removed in
commit 9765a2dfab. This also removed the
tests for memleakOnRealloc. Bring back those tests, somewhat modified
since the checker no longer checks for memory leaks.

* Add realloc to mem leak check

* Add tests of realloc buffer size

* Configure realloc functions

* Add test of freopen

* Allow to configure which element is realloc argument

* Fix wrong close in test

cppcheck now warns for this

* Update manual

* Update docs

* Rename alloc/dalloc/realloc functions

Naming the member function realloc caused problems on appveyor. Rename
the alloc and dealloc functions as well for consistency.

* Change comparisson order

* Remove variable and use function call directly

* Create temporary variable to simplify

* Throw mismatchError on mismatching allocation/reallocation

* Refactor to separate function

* Fix potential nullptr dereference

As pointed out by cppcheck.

Rikard Falkeborn 60a213e6a5 Fix #9047 (c-style casts before malloc) (#1930)
* Fix #9047 (c-style casts before malloc)

Note that there are still no warnings for c++-style casts

* Fix memleak check with casts of assignments in if-statements

* Fix possible null pointer dereference

As pointed out by cppcheck.

* Add check of astOperand2 when removing casts

This is similar to how it is done in other checks.

Library: Enhance minsize configuration and allow simple values. (#1736)
Some POSIX and Windows functions require buffers of at least some
specific size. This is now possible to configure via for example this
minsize configuration: `<minsize type="value" value="26"/>`.
The range for valid buffer size values is 1 to LLONG_MAX

versat 6f7612de03 boost.cfg: Add argument directions; some fixes; rearrange and document.
- Remove redundant function configurations for the same function since
it is not (yet) possible to configure overloaded functions. Instead mark
the optional arguments with `default="0"` so the configuration works
with a different number of arguments.
- Add documentation to boost.cfg (links and function declarations).
- Rearranged configurations so functions, defines, ... are together now.
- Add `direction` for function arguments where applicable.
- Add some tests to boost.cpp.
