2019-05-07dialyzer: Add test cases with indentationHans Bolinder
A smallish selection of already existing tests, run with the indentation option.
2019-05-07dialyzer: Add an --no_indentation optionHans Bolinder
By default Dialyzer tries to improve the readability of warnings. Newlines are inserted before and inside types, signatures, and Erlang code. Sometimes the newlines look misplaced. The raw format (option --raw) is not affected. Use the new --no_indentation option get the old behavior (no inserted line breaks). A note on the implementation. The types &c present in the warning tuples are parsed, and then formatted using erl_pp, the Erlang Pretty Printer. The alternative, to create message tuples with formatted types, turned out to more complicated, and has no real benefits. Also notice that the fixes for binaries (commit 9db8a098) and union elements (commit a1e51d12) are required. As a consequence, messages created before these commits using the --raw option cannot always be indented.
2019-05-03stdlib: Do not allow specs for functions in other modulesHans Bolinder
See also https://bugs.erlang.org/browse/ERL-845. [Kostis:] My suggestion is that the compiler refuses to compile modules that contain specs for functions that are not from this module. I do not remember when / why this `feature' was introduced, but thinking about it I see a lot of (ugly) semantics issues with it. For example, should one be allowed to declare in the foo module that lists:flatten/1 takes an integer() as an argument and returns a binary()? Should one be allowed to declare a spec in some module m1 for a function of m2 that is not defined in m2? There are all kinds of checks that will need to be added to dialyzer to protect itself from these semantics issues. The compiler already refuses to compile modules that contain specs for non-existing functions of the module. Similarly, it should refuse to compile modules that contain specs for functions of other modules - unless it can somehow check that these functions are indeed defined, but it is not how the compiler currently works.
2019-04-29dialyzer: Add parentheses around annotated union elementsHans Bolinder
In contracts, annotated elements of unions are printed with parentheses around them. They are not parseable otherwise.

2019-04-08dialyzer: Fix pretty printing of binariesHans Bolinder
Notice the comment in dialyzer_utils: %% Copied from core_pp. The function cerl:binary_segments/2 should/could %% be extended to handle literals, but then the cerl module cannot be %% HiPE-compiled as of Erlang/OTP 22.0 (due to <<I:N>>). When at it: simplify some common cases like "/binary-unit:8".

2019-02-21dialyzer: Fix key check of lists:key{search,member,find}()Hans Bolinder
Replace integers and floats with t_number() since keysearch et al compare the key (rather than match). Corrects the commit b3c8e94.

2018-12-12Add empty 'since' attribute for old modules and functionsSverker Eriksson
2018-10-01Introduce the no_spawn_compiler_process optionJosé Valim
By default, all code is compiled in a separate process which is terminated at the end of compilation. However, some tools, like Dialyzer or compilers for other BEAM languages, may already manage their own worker processes and spawning an extra process may slow the compilation down. In such scenarios, you can pass this option to stop the compiler from spawning an additional process. This generalizes commit 657760e18087b0cdbaecc5e96e46f6f66bc9497a.

uabboli/hasse/dialyzer/improve_guards/OTP-15268/ERL-680 dialyzer: Improve handling of complex guards
2018-08-28dialyzer: Improve handling of complex guardsHans Bolinder
See also https://bugs.erlang.org/browse/ERL-680. The right associative short circuit expressions 'andalso' and 'orelse' are expanded by the Compiler (see v3_core) into 'case' expressions. If parentheses are used to enforce left associativeness, variables are introduced, and the time needed by Dialyzer increases exponentially. Rather than trying to fix Dialyzer itself, v3_core now rewrites repeated use of 'andalso' ('orelse') into right associative expressions before creating the 'case' expressions.

I did not find any legitimate use of "can not", however skipped changing e.g RFCs archived in the source tree.
2018-07-23Refine types of functions in maps moduleMichał Muskała
This only touches functions that are not further manually enhanced in erl_bif_types. The hope is that this will allow dialyzer to discover more issues in code using maps.

2018-06-07stdlib: Move eval_str/1 from mod_esi to erl_evalHans Bolinder
See also https://bugs.erlang.org/browse/ERL-634. The utility program `erl_call' in erl_interface used to call lib:eval_str/1, which is no longer present in Erlang/OTP 21.0. The lib module was eliminated in OTP-15072, see also https://github.com/erlang/otp/pull/1786.
2018-05-25dialyzer: Refine the test for overspecified functionsHans Bolinder
The -Woverspecs (-Wspecdiffs) option generates warnings in a few more cases. The refinement is analogous to the test that -Wunderspecs already does: it checks if the contract has nothing in common with some element (see erl_types:t_elements/1) of the success typing.

Warnings are not generated for funs residing in dead code. In particular, warnings like "The created fun has no local return" are no longer generated for funs declared in clauses or functions that cannot be run.
