# Changelog
* v1.11 (January 21st 2022)
- New Checks:
- use-arrow-operator-instead-of-data
- use-static-qregularexpression
- unexpected-flag-enumerator-value
- Removed inefficient-qlist check (Fixed in Qt6)
* v1.10 (July 20th 2021)
- Requires C++17
- Fixed a -Wclazy-lambda-in-connect false-positive
- Fixed crash in copyable-polymorphic when PCH was enabled
* v1.9 (Jan 10th, 2021)
- Fixed clazy slowdown introduced in 1.8. I can be up to 4x faster now.
- range-loop was split in range-loop-detach and range-loop-reference
- Fixed -Wclazy-connect-non-signal false positives
* v1.8 (November 22nd, 2020)
- New Checks:
- qt6-qhash-signature
- qt6-header-fixes
- qt6-deprecated-api-fixes
- use-chrono-in-qtimer
- fixit for missing-qobject-macro
* v1.7 (June 29th, 2020)
- New Checks:
- overloaded signal
- invalid JNI signatures
- qstring-comparison-to-implicit-char
- qt6-qlatin1string-to-u
- connect-non-signal: Fix case where it didn't find the pmf
- qstring-arg warns when using QLatin1String::arg(int), as it casts to QChar
- Building clazy itself is 30% faster
- heap-allocated-small-trivial-type: less false-positives
* v1.6 (October 12, 2019)
- New Checks:
- heap-allocated-small-trivial-type
- signal-with-return-value
- qproperty-type-mismatch, contributed by Jean-Michaël Celerier
- Removed level3. Moved all level3 checks to manual level. Doesn't make sense to enable all of them.
Each one must be carefully considered.
- Fixed regressions with LLVM 9.0
- Minimum LLVM was bumped to 5.0
- Fixit infrastructure was overhauled
- Clazy no longer rewrites files directly, to avoid races when parallel invocations change the same header.
- Clazy now exports a yaml file with the replacements, to be applied with clang-apply-replacements.
The same way other clang tooling does it.
- The way to enable code rewrite is now: -Xclang -plugin-arg-clazy -Xclang export-fixes for clang
or -export-fixes=somefile.yaml for clazy-standalone
- All other fixit arguments and fixit env variables were removed
- Thanks to Christian Gagneraud for contributing the fixit yaml exporter!
* v1.5 (January 31st, 2019)
- New Checks:
- ifndef-define-typo
- lowercase-qml-type-name
- qrequiredresult-candidates
- New Fixits:
- range-loop now supports adding missing refs or const-ref
- range-loop now supports adding qAsConst()
- function-args-by-ref now adding missing refs or const-ref (experimental)
- Introduced CLAZY_FIXIT_SUFFIX env variable
- Removed support for the obscure -DCLAZY_BUILD_UTILS_LIB to simplify the CMakeLists.txt
- Renamed the clazy plugin from ClangLazy.so to ClazyPlugin.so
- fully-qualified-moc-types now warns for slot/invokable return values too.
They need to be fully qualified for QML.
- Fixed a crash (clang assert) in raw-environment-function
* v1.4 (September 23rd, 2018)
- New Checks:
- connect-by-name
- skipped-base-method
- qstring-varargs
- fully-qualified-moc-types
- qt-keywords, with fixit included
- qhash-with-char-pointer-key
- wrong-qevent-cast
- static-pmf
- raw-environment-function
- empty-qstringliteral
- auto-unexpected-qstringbuilder now also warns for lambdas returning QStringBuilder
- performance optimizations
- Added -header-filter=<regex> option to clazy-standalone. Only headers matching the regexp will
have warnings, besides the .cpp file from the translation unit, which is never filtered out.
- Added -ignore-dirs=<regex> option to clazy-standalone, and its CLAZY_IGNORE_DIRS env variable equivalent.
- Added CLAZY_HEADER_FILTER env variable which adds above functionality to both clazy and clazy-standalone
- unused-non-trivial-variable got unused-non-trivial-variable-no-whitelist option
- unused-non-trivial-variable got user-blacklist and user-whitelist support
- container-inside-loop is now a manual check instead of level2
- HiddenLevel was renamed to ManualLevel
- connect-3arg-lambda now warns when passing a lambda to QTimer::singleShot() or QMenu::addAction()
without a context object
- old-style-connect warns for QMenu::addAction() and QMessageBox::open() too now
* v1.3 (November 26th, 2017)
- New checks:
- thread-with-slots
- connect-3arg-lambda
- qproperty-without-notify
- virtual-signal
- overridden-signal
- qhash-namespace
- const-signal-or-slot
- lambda-unique-connection
- missing-qobject-macro is now a level2 check, instead of level1. Because, people can omit Q_OBJECT intentionally.
- Added -only-qt option, which will make clazy bailout early on non-Qt files.
For this purpose, the definition of a Qt file is whenever -DQT_CORE_LIB is passed,
which is usually the case in most build systems.
- Added -qt-developer option, when building Qt with clazy it will honour specific guidelines for Qt,
which are not many right now but the list will grow.
* v1.2 (July 8th, 2017)
- clazy-standalone executable. Allows to run clazy against a JSON compilation database
instead of as a plugin. clang-tidy doesn't support loading external modules (https://bugs.llvm.org/show_bug.cgi?id=32739)
so this is a good workaround.
- qt-compat mode. Allows to disable Qt5 specific checks by passing -Xclang -plugin-arg-clazy -Xclang qt4-compat
- New checks:
- install-event-filter
- qcolor-from-literal
- strict-iterators
- connect-not-normalized
- returning-data-from-temporary now checks for temporary QByteArrays casting to char* when returned
- returning-data-from-temporary now checks for assignment too, not only return statements
- unused-non-trivial-variable now warns for unused QList, QVector and many more types
- ASTMatchers based checks are now supported
- clang 3.7 was dropped due to ASTMatchers source incompatibilities.
- Use clazy v1.1 for clang >= 3.6 support
- clazylib.so no longer gets built by default, only the plugin (ClangLazy.so)
gets built. Pass -DCLAZY_BUILD_UTILS_LIB=ON to enable the utils library if
you're developing tools using clazy's convenience functions, which you're
probably not.
- CLAZY_INSTALL_NO_HEADERS option was removed. Either install the utils library
and headers or nothing at all. By default nothing is installed, except
the plugin and man pages.
* v1.1 (February 20th, 2017)
- macOS and Windows support
- New checks:
- child-event-qobject-cast
- ctor-missing-parent-argument
- returning-data-from-temporary
- qt-macros
- base-class-event
- connect-non-signal
- incorrect-emit
- tr-non-literal
- Fixes against :
- clang 4.0
- Qt 5.9
- 60% performance improvement
- Fixed many false positives
* v1.0 (September 12th, 2016)
- (...)
* v0.0.1 (June 10th, 2015)
- (...)
