infer_clone/Changelog.md

Version 1.1.0

Frontends

• New JSON input format for SIL. This new format was contributed from Infer#, whose C# frontend for Infer emits SIL as JSON using this format.

Build System Integrations

• Clang upgraded to version 11.0

Checkers

• Liveness: properly handle exceptional control flow
• Pulse:
  • Added preliminary Java support
  • New Uninitialized value bug type, aiming to replace the previous Uninit checker as this one is inter-procedural and more precise.
  • OPTIONAL_EMPTY_ACCESS is now enabled by default
• NEW checker Topl(early alpha): An experimental checker framework: write your own analysis as a state machine representing a temporal property over multiple memory objects at once, eg to write a taint analysis. Topl is based on Pulse.
• Miscellaneous improvements to cost, inferbo, nullsafe, racerd, starvation

Version 1.0.0

Checkers

AL is now deprecated and may be removed in future versions.

Annotation Reachability

• reporting format improvements (the trace is no longer included in the report text, only as metadata)

Biabduction

• disable some less-used bug types

Eradicate

• remove "Field not mutable" check

RacerD

• Now defaults to "angelic" ownership: an unknown function is assumed to return owned objects.
• No more reports on races on paths rooted on temporary or local variables, as these are unreliably modelled.

Litho Required Properties: new Java checker to check that all non-optional @Props have been specified when constructing Litho components. Self in Block: new Objective-C checker to detect when an Objective-C block incorrectly captures self Starvation

• New experimental "global" analysis mode. Enable with --starvation-whole-program

Miscellaneous improvements to most checkers, in particular Annotation Reachability, Cost Analysis, Eradicate, Inefficient Keyset Iterator, InferBO, Pulse, RacerD, Starvation, and Uninitialized Value.

Build System Integrations

• The Gradle integration now captures Java files in parallel
• New Buck integration for Java, enable with --buck-java-flavor
• Clang upgraded to version 9.0

Command Line Interface

• New subcommand infer help to display information about checkers and issue types.
• New subcommand infer debug that replaces the uses of infer explore not related to reported issues.
• --debug no longer disables filtering, you have to pass -g -F to get the previous behaviour back.
• All disk artefacts (except the Java type environment) are now stored in the SQLite database in infer-out/results.db. The contents of the database can be explored with infer debug.
• Changed how to select the Buck integration. The old command line interface is still supported but is now deprecated.
  • clang via "flavors", activated with --flavors, now with --buck-clang
  • clang via "compilation DB", activated with --buck-compilation-database, unchanged
  • Java via "genrule", activated with --genrule-master-mode, now with --buck-java
  • Java "without genrules", used to be activated by not specifying any other Buck mode, deleted
  • In addition, there is a new Java integration, activated with --buck-java-flavor
• The textual version of the report infer-out/bugs.txt has moved to infer-out/report.txt. The bugs.txt file is still created with dummy contents to allow for a smooth transition.
• Removed the --report-hook option.
• Properly terminate on Control-C instead of sometimes leaving around zombie processes.
• Spec files (summaries) are now stored in the database. Explore with infer debug --procedures --procedures-summary.

Documentation

• Revamped online documentation for bug types and checkers. See the list of all issue types and the pages for each checker. The infer help command can be used locally to also get this information and more.
• Access the documentation for previous and future versions online.
• The https://fbinfer.com/ website now uses Docusaurus 2.

Internal Changes

• Folded the facebook-clang-plugins sub-repo inside the infer repository; there is no more git submodule for it.
• Improve internal documentation of OCaml source code.
• Build with OCaml 4.11.1 and dune 2.7.1
• Migrated our Python 2 code to OCaml
• Split the infer OCaml source code into individual dune libraries.
• Better defaults for SQLite, and a write daemon to reduce contention.
• New analysis schedulers that speed up the analysis phase. Enable with --scheduler callgraph or --scheduler restart.
• Infer no longer builds by default in "opt" mode (optimised, using OCaml’s flambda pass). The default is now "dev", which does not include as many optimisations (hence builds faster) and turns warnings into errors.
• The starvation checker is now based on SIL instead of HIL.

Version 0.17.0

• There's a new --inefficient-keyset-iterator checker for finding inefficient uses of Java's keyset iterators that retrieve both key and value (on by default).
• Complete the set of Android thread annotations and Java nullability annotations. Updated artifacts are available on Maven Central.
• --starvation is now on by default. This analysis catches problems with threads not being able to make progress due to locking issues, incorrect scheduling priorities, etc. For instance, on Android calling Future.get from a UiThread without a sensible timeout will be flagged as a starvation issue.
• New Objective-C linter for calls to @optional methods: UNSAFE_CALL_TO_OPTIONAL_METHOD, enabled by default.
• A new call-graph scheduler (--call-graph-schedule) improves performance of the analysis phase of Infer, especially when the number of files to analyze is less than available CPUs.
• A new flag --oom-threshold allows to throttle the analysis when the amount of free memory is below the provided threshold.
• New genrule based Buck/Java integration is much faster than the previous one, use with --genrule-master-mode.
• Infer's internal clang is now in version 8.0.0.
• Update to javalib 3.1 provides better compatibility with Java 9 and Java 11. Refer to their change log for more details.
• Infer can now be built and run on MacOS Mojave without fiddling with SDKROOT (although you still might need it with non-standard toolchain setup).
• [β] Pulse is a new experimental lifetime analysis for C++, give it a try with --pulse. Beware that it doesn't report much yet.
• --ownership checker was superseded by Pulse and removed.

Version 0.16.0

Backend analyses:

• A brand new analysis to compute the runtime cost of methods and functions: passing --cost (off by default) to Infer will output a costs-report.json file describing, among others, the computational complexity of each function in the code using the big-O notation, eg O(1), O(list.length), ...
• The deadlock detection analysis has been ported to C++ and Objective-C and mainly focuses on self-deadlocks (taking a mutex twice). Activate with --starvation (off by default).
• The data race detector RacerD has been ported to Objective-C and detects races on fields protected by a C++ mutex. It reports "Thread Safety Violation" and "GuardedBy Violation" errors on Java and "Lock Consistency Violation" on C++ and Objective-C. Activate with --racerd (on by default).
• A progress bar is displayed while the analysis is running
• Countless improvements and tweaks, in particular in RacerD and in analyses for C++.

Frontends:

• Infer now ships with clang version 7.0.1
• Support for Java up to version 11

Version 0.15.0

• switch infer license to MIT
• publish binaries
• [clang] lots of improvements to the frontend

Version 0.14.0

• New checker: --ownership detects a subset of use-after-free issues due to bad manual memory management. This is a rough prototype of Rust-style borrow checker for C++. (enabled by default, C++)
• New checker: --uninit detects uses of uninitialized values (enabled by default, C/C++/Objective-C)
• New checker: --racerd now also detects inconsistent lock usage in C++. Also improved the lock domain to reduce false positives for all languages.
• Improved C++ support: destructors are now properly translated; addresses and pointers are handled more precisely
• Improved retain cycles detection (Objective-C)
• Upgraded the internal clang to clang 7
• [internal] SQLite is being used to store some of infer's analysis artefacts instead of storing them in files on disk. This improves analysis speed and reduces load on the OS.

Version 0.13.1

This is a fix for the 0.13.0 release, whose build broke due to changes in opam.

Version 0.13.0

• Infer now runs multiple checkers at the same time by default, including the biabduction analysis that was the previous and only default. In particular, we are pleased to introduce RacerD for race detection in Java. The following checkers are activated by default: annotation reachability (Java), biabduction (C/C++/ObjC, Java), fragment retains view (Java), immutable cast (Java), liveness (C/C++/ObjC), printf args (Java), quandary (C/C++/ObjC, Java), RacerD (C/C++/ObjC, Java), SIOF (C/C++/ObjC). Each checker may report several issue types.
• Upgraded to clang 5.0
• Richer DSL for writing linters (AL), and a new default linter for const pointers in Objective-C
• Lots of perf improvements and bug fixes, and improved logging

Please note the following breaking changes:

• -a eradicate is now simply --eradicate and can run alongside other checkers
• inferTraceBugs is now the explore subcommand: infer explore --help
• infer now depends on sqlite

Version 0.12.1

Hotfix release to update infer's opam dependencies to cope with upgrades of cppo in opam (in particular, #718).

Version 0.12.0

• introduces subcommands and man pages for all subcommands
• This release introduces AL, a language for writing linters against the clang AST. AL lets you check syntactic properties of source code by traversing the AST of the program. Using the included domain-specific language (DSL), you can write your own set of checks.

Version 0.11.0

• [Java] ThreadSafety analyzer is now on by default; run it with infer -a checkers .... This checker will try and detect races (unprotected concurrent accesses with at least one write) in classes bearing the @ThreadSafe annotation.
• Infer now builds using OCaml 4.04.0.

Version 0.10.0

• [Clang] C++ support.
• [Clang] Improved support for cmake and Xcode compilation databases. Use with infer --compilation-database compile_commands.json (for cmake and Buck), or with infer --compilation-database-escaped compile_commands.json (for xcbuild and xcpretty).
• [C++] New SIOF Checker.
• [iOS] New linter for target SDK version. Use with infer --iphoneos-target-sdk-version <min version you support> ... or with infer -a linters --iphoneos-target-sdk-version <min version you support> ....
• [Java] New Thread Safety Checker.
• [Java] Smarter analysis of dynamic dispatch.
• [Java] Improved Maven integration.
• [Java] @SuppressWarnings support removed. Use @SuppressLint instead. android.annotation.SuppressLint is only available on Android, but do let us know if that is an issue for you.
