orbitcowboy a5ca3cb1f0 wxwidgets.cfg: Fixed FP for wxSizer::Add() 2020-02-26 16:10:10 +01:00

qt.cfg: #9650: Fix missing configuration for QString.chop() (#2556)
chop() and also remove() change the size of a QString, so they have to
be added in the container configuration accordingly to avoid false
positives.

gtk.cfg: Fix syntax errors and false positives (#2552)
A missing definition for g_assert_cmp*() causes syntax errors if code
like g_assert_cmpint(a, ==, b); is encountered.
The function g_hash_table_iter_replace() does not have to be marked
with leak-ignore since the memory could be freed later if corresponding
functions are present in the GHashTable. Since we can not know if this
is the case we have to assume that the memory is freed to avoid false
positives. The same is true for g_hash_table_insert() and
g_hash_table_replace().

Paul Fultz II ba037837c9 Track lifetime across multiple returns
This will now warn when doing something like this:

```cpp
template <class T, class K, class V>
const V& get_default(const T& t, const K& k, const V& v) {
    auto it = t.find(k);
    if (it == t.end()) return v;
    return it->second;
}
const int& bar(const std::unordered_map<int, int>& m, int k) {
    auto x = 0;
    return get_default(m, k, x);
}
```

The lifetime warning is considered inconclusive in this case.

I also updated valueflow to no tinject inconclusive values unless `--inconclusive` flag is passed. This creates some false negatives because library functions are not configured to not modify their input parameters, and there are some checks that do not check if the value is inconclusive or not.

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

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

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

with a different number of arguments.

To be able to use real Qt-Code in "test/cfg/qt.cpp" and still do a

available. This way the test now can contain Qt macros and functions and
the syntax check can still be used.
Additionally the same options as for the other tests are used now for
the Qt config tests.
Installing the package "qtbase5-dev" should be enough to enable the
syntax checks (already installed for travis tests).

* #4241: Check for address of single character passed as string

Add a check that address of a single character is not passed as argument
to argument marked as strings (using strz). The check does not warn if
the address of a character with known value '\0'.

Since ValueFlow currently does not handle global constants (see #7597),
do not warn if the variable is global to avoid FPs when the address of
a global variable assigned to '\0' is passed to a function expecting a
string.

Remove comment in docs saying strz is unused.

* Change asdf to Hello world

* Add test of address to first element in string

* Add error reporting function to getErrorMessages

Windows library: Enhance functions, add tests (#1117)
Enhance *Equal/*Compare/*Copy/*Move/*Zero/*Fill memory functions to
catch buffer access out of bounds errors and ignored return values.
Replaced some function configuration by according defines as it is done
in windows to avoid redundant (and error prone) configurations.

Sebastian 7ba9ab7e4c Gtk library: Add configuration to avoid syntax error, add test file (#1109)
Add configuration for G_UNLIKELY and G_LIKELY to avoid syntax errors
when these macros are used as condition without enclosing brackets.
Add test file to verify Gtk library configuration. Syntax check for the
test file is only done when Gtk+2.0 or Gtk+3.0 is found and working.
Tested on Cygwin and on Ubuntu 16.04.

Add Windows Socket 2 type/function configuration. There are still many
(microsoft specific) socket functions that are not yet configured.
Add configuration for GetUserName(), GetWindowText() and _fileno().
On Windows __wchar_t is a synonym for wchar_t, so an according define is
added.

wxwidgets: Fix syntax checking errors and warning (#1093)
wxDebugContext is only defined if wxUSE_DEBUG_CONTEXT is 1, so otherwise
just skip it for syntax checking because it will fail.
Change wxT to wxT_2 and add wxT_2 to the config to remove a warning
during syntax check and be more compatible with newer/older wxwidgets
versions.
Be more precise when replacing function like macros, fix redundant macro
definition for "_".

std library: Resolve two TODOs (#1074)
First resolved TODO in std.c is obsolete since the "res" variable is used later
and there is therefore no warning issued.
Second resolved TODO in std.c: A warning for uninit variables is issued by
cppcheck, so this check can be enabled. Since assert() has no noreturn configuration
(currently a useful configuration is not really possible, see ticket 8329) the
check-library message is suppressed.

functions that arised through the tests and were already fixed for the
normal string functions.

Sebastian 170d60712f wxwidgets library tests: Add syntax checking, fix test file. (#1084)
For the syntax check g++ needs to know the wxWidgets include paths which
are retrieved via wx-config. If includes are missing or not working the
syntax check is skipped.
wxwidgets.cpp: Fixed syntax, includes and added code so the syntax check
does not fail if some special features are not present.

wxwidgets library: Fix/Enhance cfg, add test file (#1082)
Add test file for wxwidgets configuration, fix found issues and enhance
the cfg a bit:
Fix declarations in comments for wxLog* functions.
Merge the two wxTextFile::Create overloaded function configurations into
one that works for both now.
Removed use-retval attribute from wxBoxSizer::AddSpacer and
wxButton::SetDefault configuration since the functions have side effects
and there is no need to use the return value.
Add some function configurations, the macro _(str) and POD wxLogLevel.

test/cfg/windows.cpp: Added tests for strlwr and strupr. Moved function
call that does not return (FreeLibraryAndExitThread) to the end of the
function to fix analysis that was silently aborted at that point
(reported as issue #8378).

Sebastian b78d714037 posix.cfg: access(): Removed redundant configuration, added tests (#1048)
I intentionally removed the second access() configuraion because it was
missing the use-retval attribute. But calling access() without using the
return value is absolutely senseless.
I added tests to posix.c to verify the correct configuration of
access().

Sebastian de7aa8f513 Fix #7504: posix: open() was twice in configuration file (#1032)
* Fix #7504: posix: open() was twice in configuration file

This fixes ticket #7504: Problems with the open function were not always
detected because the open function was twice in posix.cfg and only the
second configuration was used by cppcheck. Like suggested now only
one configuration is used and the third parameter has a default value
and is thereby optional.
use-retval has been removed to avoid duplicate warnings because the
alloc/dealloc configuration already warns about unused retval.
According tests to verify that open is configured
correctly now have been added to test/cfg/posix.c.

* posix.cfg: open(): Add TODO for use-retval configuration
