Fix #10412 FN useStlAlgorithm with iterators (#4157) 2022-10-16 13:46:26 +02:00

various optimizations (#4535) 
* avoid potentially duplicated `strTolower()` call in `Path::getFilenameExtensionInLowerCase()`

* avoid unnecessary copies

* use `unordered_*` containers for faster lookups

* symboldatabase.cpp: do not perform call in `checkReturns()` until needed

* astutils.cpp: do not perform calls in `isVariableChangedByFunctionCall()` until necessary

* tokenize.cpp: small `hasIfDef()` optimization

* use `unordered_map` for `CheckUnusedFunctions::FunctionUsage::mFunctions` / adjusted test case

Library: Replace auto with real types (#4207) 
Following up on fc6c203b0e76, replace auto with the correct types to
clairfy the code. Note the use of const on the first type in the pair,
which allows us to use a reference.

library: Add new warning: ignoredReturnErrorCode (#2877) 
* library: Add optional "type" attribute to "use-retval"

Added an optional "type" attribute to "use-retval" nodes in the
configuration. When the return type of a function configured with
`<use-retval type="error-code"\>` node does not used, the new style
error "ignoredReturnErrorCode" will be generated.

* Fix and improve patch after the initial review

* Fixed severity level and [[nodiscard]] attribute

* Fix incorrect condition

* Remove redundant condition
