* 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.
This will warn for cases where searching in an associative container happens before insertion, like this:
```cpp
void f1(std::set<unsigned>& s, unsigned x) {
if (s.find(x) == s.end()) {
s.insert(x);
}
}
void f2(std::map<unsigned, unsigned>& m, unsigned x) {
if (m.find(x) == m.end()) {
m.emplace(x, 1);
} else {
m[x] = 1;
}
}
```
In the case of the map it could be written as `m[x] = 1` as it will create the key if it doesnt exist, so the extra search is not necessary.
I have this marked as `performance` as it is mostly concerning performance, but there could be a copy-paste error possibly, although I dont think thats common.
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
(9223372036854775807)
There are important TODOs still; for instance adding CTU support using our CTU infrastructure, add handling of pointers (maybe I'll use FwdAnalysis for this), add handling of multidimensional arrays, etc..
* std.cfg: Add further argument directions (in, out, inout).
* testlibrary.cpp: Add test for function argument direction configuration.
* std.cfg: runastyle and add some more direction configurations.
* library.h: Add documentation for function argument direction enum.
* Do not use "direction" library information for pointer arguments.
Also fix further unmatched uninitvar messages in std configuration
tests.
* std.cfg: Add more argument direction configurations.
* test/cfg/std.c: Add test for argument direction configuration.
* astutils.cpp: Only ignore pointer arguments for out/inout arguments.
* library.h: Use suggested documentation for argument direction enum.
This enhances the library configuration so the direction of function
arguments can be specified (in, out, inout).
isVariableChangedByFunctionCall() uses this information now to avoid
guessing.
* Add tests for invalid ranges
* Refactor loadLibErrors
This reduces the amount of code slightly and will simplify adding
more tests.
* Handle empty valid field
Before this change, the sequence <valid></valid> in a config file would
result in a segmentation fault. Now an empty field results in the error
message:
cppcheck: Failed to load library configuration file 'mycfg.cfg'. Bad attribute value '""'
* Add support for valid for floating point arguments
Previously, it was not possible to add valid ranges to floating point
arguments since it only handled integers. This made ranges not work well
for floating point arguments since arguments were cast to integers
before the ranges were handled.
Fix this by using doubles instead of integers if the argument is a float.
Add some tests for this and make sure errors are printed with enough
precision (somewhat arbitrarily chosen).
Note that it is still only possible to add integer ranges (i.e. -1:1).
* Add support for floats in configuration valid range
Now that it is possible to handle decimal arguments, there is no reason
to not allow non-integer ranges. Take care to not allow broken
configurations.
* Move check to within if-clause
* Move asin{,f,l} and acos{,f,l} input checks to config file
1) Added global static const std::string emptyString; object:
-> Replaces some static variables in functions which might be not threadsafe
-> Avoids constructor call (std::string::string(""))
-> Even functions that return an empty string in some branches can return by reference now.
Added to config.h to ensure that it is available everywhere
2) Added overloads for TestFixture::assertEquals for the most common use cases:
-> Moves conversion from const char[] to std::string into a function, reducing code duplication in binary.
This tag will allow to add some preprocessor defs into library.
It would be useful to provide more information about libraries
implementation details. As example GLib's library include tag
was added that helps to detect more memory leaks.
