(Thanks!) <li>Added -exclude and -outputDir command line options to rejarForAnalysis <li>Extended -adjustPriorities option to FindBugs analysis textui so that you can modify the priorities of individual bug patterns as well as visitors, and also completely suppress individual bug patterns or visitors. <ul> <li> e.g., -adjustPriority MS_SHOULD_BE_FINAL=suppress,MS_PKGPROTECT=suppress,EI_EXPOSE_REP=suppress,EI_EXPOSE_REP2=suppress,PZLA_PREFER_ZERO_LENGTH_ARRAYS=raise </ul> </ul> <p> Changes since version 1.3.5</p> <ul> <li>Added fairly exhaustive static analysis of uses of format strings, checking for missing or extra arguements, invalid format specifiers, or mismatched format specifiers and arguments (e.g, passing a String value for a %d format specifier). The logic for doing so is derived from Sun's java.util.Formatter class, and available separately from FindBugs as part of the <a href="https://jformatstring.dev.java.net/">jFormatString</a> project. <li>More tuning of the unsatisfied obligation detector. Since this detector is still rather noisy and an unfinished research project, I've moved the generated issues to a new category: EXPERIMENTAL. <li>Added check for <a href="http://findbugs.sourceforge.net/bugDescriptions.html#BIT_ADD_OF_SIGNED_BYTE">BIT_ADD_OF_SIGNED_BYTE</a>; similar to <a href="http://findbugs.sourceforge.net/bugDescriptions.html#BIT_IOR_OF_SIGNED_BYTE">BIT_IOR_OF_SIGNED_BYTE</a>, except that addition is being used to combine shifted signed bytes. <li>Changed detection of EI_EXPOSE_REP2, so we only report it if the value stored is guaranteed to be the same value that was passed in as a parameter. <li>Added <a href="http://findbugs.sourceforge.net/bugDescriptions.html#EQ_CHECK_FOR_OPERAND_NOT_COMPATIBLE_WITH_THIS">EQ_CHECK_FOR_OPERAND_NOT_COMPATIBLE_WITH_THIS</a>, a warning when an equals method checks to see if an operand is an instance of a class not compatible with itself. For example, if the Foo class checks to see if the argument is an instance of String. This is either a questionable design decision or a coding mistake. <li>Added <a href="http://findbugs.sourceforge.net/bugDescriptions.html#DMI_INVOKING_HASHCODE_ON_ARRAY">DMI_INVOKING_HASHCODE_ON_ARRAY</a>, which checks for invoking <code>hashCode()</code> on an array, which returns a hash code that ignores the contents of the array. <li>Added checks for using <code>x.removeAll(x)</code> to rather than <code>x.clear()</code> to clear an array. <li>Add checks for calls such as <code>x.contains(x)</code>, <code>x.remove(x)</code> and <code>x.containsAll(x)</code>. <li>Improvements to Eclipse plugin (thanks to Andrei Loskutov): <ul> <li>Report separate markers for each occurrence of an issue that appears multiple times in a method <li> fine tuning for reported markers: add only one marker for fields, add marker on right position <li> link bugs selected in bug explorer view to the opened editor and vice versa <li> select bugs selected in editor ruler in the opened bug explorer view <li> consistent abbreviations used in both bug explorer and bug details view <li> added "Expand All" button to the bug explorer view <li> added "Go Into/Go Up" buttons to the bug explorer view <li> added "Copy to clipboard" menu/functionality to the details view list widget <li> fix for CNF exception if loading the backup solution for broken browser widget </ul></ul> <p> Changes since version 1.3.4</p> <ul> <li>Analysis about 15% faster <li><a href="http://sourceforge.net/tracker/?atid=614693&group_id=96405&func=browse&status=closed">38 bugs closed</a></li> <li>New defect warnings: <ul> <li>calls to methods that always throw UnsupportedOperationException (DMI_UNSUPPORTED_METHOD) <li>repeated conditional tests (e.g., <code>if (x < 0 || x < 0) ...</code>) (RpC_REPEATED_CONDITIONAL_TEST) <li>Complete rewrite of detector for format string problems. More accurate, finds more problems, generates more descriptive reports, several different bug pattern (VA_FORMAT_STRING_EXTRA_ARGUMENTS_PASSED, VA_FORMAT_STRING_ILLEGAL, VA_FORMAT_STRING_MISSING_ARGUMENT, VA_FORMAT_STRING_BAD_ARGUMENT, VA_FORMAT_STRING_NO_PREVIOUS_ARGUMENT) <li>Fairly complete implementation of JSR-305 custom type qualifier analysis (no support for custom validators yet). (TQ_MAYBE_SOURCE_VALUE_REACHES_NEVER_SINK TQ_EXPLICIT_UNKNOWN_SOURCE_VALUE_REACHES_ALWAYS_SINK TQ_EXPLICIT_UNKNOWN_SOURCE_VALUE_REACHES_NEVER_SINK) <li>New detector for unsatisfied obligations such forgetting to close a file (OBL_UNSATISFIED_OBLIGATION). <li>Warning when a parameter is marked as nullable, but is always dereferenced. (NP_PARAMETER_MUST_BE_NONNULL_BUT_MARKED_AS_NULLABLE) <lI>Separate warning for dereference the result of readLine (NP_DEREFERENCE_OF_READLINE_VALUE) </ul> <li>When XML is generated with messages, the project stats now include <FileStat> elements. For each source file, this gives the path for the file, the total number of warnings for that file, and a bugHash for the file. While the instanceHash for a bug is intended to be version invariant (ignoring line numbers, etc), the bugHash for a file is intended to reflect all the information about the warnings in that file. The intended use case is that if the bugHash for a file is the same in two analysis runs, then <em>nothing</em> has changed about any of the warnings reported for that file between the two analysis runs. <li>More merging of similar issues within a method. For example, if the result of readLine() is dereferences multiple times within a method, it will be reported as a single warning with occurrences at multiple source lines. </ul> <p> Changes since version 1.3.3</p> <ul> <li>FindBugs base <ul> <li>New Reports:</li> <ul> <li>EQ_OVERRIDING_EQUALS_NOT_SYMMETRIC: equals method overrides equals in superclass and may not be symmetric</li> <li>EQ_ALWAYS_TRUE: equals method always returns true</li> <li>EQ_ALWAYS_FALSE: equals method always returns false</li> <li>EQ_COMPARING_CLASS_NAMES: equals method compares class names rather than class objects</li> <li>EQ_UNUSUAL: Unusual equals method</li> <li>EQ_GETCLASS_AND_CLASS_CONSTANT: equals method fails for subtypes</li> <li>SE_READ_RESOLVE_IS_STATIC: The readResolve method must not be declared as a static method.</li> <li>SE_PRIVATE_READ_RESOLVE_NOT_INHERITED:⌨️ 快捷键说明
