7.0.8: PHP 7.0 Sniffs - update 2016-10-31 - Spooky !

PHP 7.0 Sniffs - update 2016-10-31 - Spooky !

See all related issues and PRs in the 7.0.8 milestone.

Added

• 🌟 New ForbiddenNamesAsDeclared sniff: detection of the other reserved keywords which are reserved as of PHP 7.0 (or higher). #287. Fixes #115.
  These were previously sniffed for by the ForbiddenNames and ForbiddenNamesAsInvokedFunctions sniffs causing false positives as the rules for their reservation are different from the rules for "normal" reserved keywords.
• ⭐ New inUseScope() utility method to the PHPCompatibility_Sniff class which handles PHPCS cross-version compatibility when determining the scope of a use statement. #271.
• ☔ More unit tests for the ForbiddenNames sniff. #271.

Changed

• 📌 Deprecated functionality should throw a warning. Removed or otherwise unavailable functionality should throw an error. This distinction was previously not consistently applied everywhere. #286
  This change affects the following sniffs:
  • DeprecatedPHP4StyleConstructors will now throw a warning instead of an error for deprecated PHP4 style class constructors.
  • ForbiddenCallTimePassByReference will now throw a warning if the testVersion is 5.3 and an error if the testVersion if 5.4 or higher.
  • MbstringReplaceEModifier will now throw a warning instead of an error for usage of the deprecated e modifier.
  • PregReplaceEModifier will now throw a warning if the testVersion is 5.5 or 5.6 and an error if the testVersion if 7.0 or higher. Fixes #290.
  • TernaryOperators will now throw an error when the testVersion < 5.3 and the middle part has been omitted.
  • ValidIntegers will now throw a warning when an invalid binary integer is detected.
• ✏️ DeprecatedFunctions and DeprecatedIniDirectives sniffs: minor change in the sniff error message text. Use "removed" rather than the ominous "forbidden". #285
  Also updated relevant internal variable names and documentation to match.

Fixed

• 🐛 ForbiddenNames sniff would throw false positives for use statements which changed the visibility of methods in traits. #271.
• 🐛 ForbiddenNames sniff would not report reserved keywords when used in combination with use function or use const. #271.
• 🐛 ForbiddenNames sniff would potentially - unintentionally - skip over tokens, thereby - potentially - not reporting all errors. #271.
• 🔧 Composer config: prefer-stable should be a root element of the json file. Fixes #277.

Fixed

• 🐛 The DeprecatedPHP4StyleConstructors sniff would not report errors when the case of the class name and the PHP4 constructor function name did not match. #236
• 🐛 LongArrays sniff would report false positives for class properties shadowing removed PHP superglobals. #270. Fixes #268.
• 🐛 The NewClasses sniff would not report errors when the case of the class name used and "official" class name did not match. #237
• 🐛 The NewIniDirectives sniff would report violations against the PHP version in which the ini directive was introduced. This should be the version below it. #246
• 🐛 PregReplaceEModifier sniff would report false positives for compound regex parameters with different quote types. #266. Fixes #265.
• 🐛 RemovedGlobalVariables sniff would report false positives for lowercase/mixed cased variables shadowing superglobals. #245.
• 🐛 The RemovedHashAlgorithms sniff would not report errors when the case of the hash function name used and "official" class name did not match. #240
• 🐛 The ShortArray sniff would report all violations on the line of the PHP open tag, not on the lines of the short array open/close tags. #238

• 🔧 The unit tests for the utility methods have been moved to their own subdirectory within Tests. #215
• 💚 The sniffs are now also tested against PHP 7.1 for consistent results. #216

Removed

Fixed

• 🐛 TernaryOperators sniff: the version check logic was reversed causing the error not to be reported in certain circumstances. #188

• 🐛 The getFunctionCallParameters() utility method would incorrectly identify an extra parameter if the last parameter passed to a function would have an - unnecessary - comma after it. The getFunctionCallParameters() utility method also did not handle parameters passed as short arrays correctly. #213. Fixes #211.
• ☔ Unit tests for the NewFunctionArrayDereferencing sniff were not being run due to a naming error. #208

7.0.2: PHP 7.0 Sniffs - update 2016-08-03

Fixes + improvements on 7.0.1

See all related issues and PRs in the 7.0.2 milestone.

Added

• ⭐ RemovedExtensions sniff: ability to whitelist userland functions for which the function prefix overlaps with a prefix of a deprecated/removed extension. #130. Fixes #123.

All PHP 7.0 sniffs + fixes for sniffs for previous versions

See all related issues and PRs in the 7.0.1 milestone.

Changed

• 📌 The DeprecatedIniDirectives sniff used to throw an error when a deprecated ini directive was used in combination with ini_get(). It will now throw a warning instead. #122 Fixes #119.

Removed

• 🔧 Duplicate builds from the Travis CI build matrix. #132

Fixed

• 🐛 The PregReplaceEModifier sniff failed to detect the e modifier when using bracket delimiters for the regex other than the {} brackets. #128
• 💚 Unit tests failing against PHPCS 2.6.1.
