From 25ab719cfaf42d196287fec2171bf3eefb845b62 Mon Sep 17 00:00:00 2001 From: Hans Bolinder Date: Wed, 30 Apr 2014 09:11:34 +0200 Subject: dialyzer: Introduce module local suppression of warnings The -dialyzer() attribute can be used for suppressing warnings in a module by specifying functions or warning options. It can also be used for requesting warnings in a module. --- lib/dialyzer/src/dialyzer_succ_typings.erl | 46 ++++++++++++++---------------- 1 file changed, 22 insertions(+), 24 deletions(-) (limited to 'lib/dialyzer/src/dialyzer_succ_typings.erl') diff --git a/lib/dialyzer/src/dialyzer_succ_typings.erl b/lib/dialyzer/src/dialyzer_succ_typings.erl index 6dc4285194..7ceb19e30a 100644 --- a/lib/dialyzer/src/dialyzer_succ_typings.erl +++ b/lib/dialyzer/src/dialyzer_succ_typings.erl @@ -29,7 +29,7 @@ -export([analyze_callgraph/3, analyze_callgraph/6, - get_warnings/8 + get_warnings/7 ]). -export([ @@ -69,10 +69,8 @@ -type scc() :: [mfa_or_funlbl()] | [module()]. - -record(st, {callgraph :: dialyzer_callgraph:callgraph(), codeserver :: dialyzer_codeserver:codeserver(), - no_warn_unused :: sets:set(mfa()), parent = none :: parent(), timing_server :: dialyzer_timing:timing_server(), solvers :: [solver()], @@ -137,18 +135,17 @@ get_refined_success_typings(SCCs, #st{callgraph = Callgraph, -type doc_plt() :: 'undefined' | dialyzer_plt:plt(). -spec get_warnings(dialyzer_callgraph:callgraph(), dialyzer_plt:plt(), - doc_plt(), dialyzer_codeserver:codeserver(), sets:set(mfa()), + doc_plt(), dialyzer_codeserver:codeserver(), dialyzer_timing:timing_server(), [solver()], pid()) -> - {[dial_warning()], dialyzer_plt:plt(), doc_plt()}. + {[raw_warning()], dialyzer_plt:plt(), doc_plt()}. get_warnings(Callgraph, Plt, DocPlt, Codeserver, - NoWarnUnused, TimingServer, Solvers, Parent) -> + TimingServer, Solvers, Parent) -> InitState = init_state_and_get_success_typings(Callgraph, Plt, Codeserver, TimingServer, Solvers, Parent), - NewState = InitState#st{no_warn_unused = NoWarnUnused}, - Mods = dialyzer_callgraph:modules(NewState#st.callgraph), - MiniPlt = NewState#st.plt, + Mods = dialyzer_callgraph:modules(InitState#st.callgraph), + MiniPlt = InitState#st.plt, FindOpaques = lookup_and_find_opaques_fun(Codeserver), CWarns = dialyzer_contracts:get_invalid_contract_warnings(Mods, Codeserver, @@ -156,31 +153,30 @@ get_warnings(Callgraph, Plt, DocPlt, Codeserver, MiniDocPlt = dialyzer_plt:get_mini_plt(DocPlt), ModWarns = ?timing(TimingServer, "warning", - get_warnings_from_modules(Mods, NewState, MiniDocPlt)), + get_warnings_from_modules(Mods, InitState, MiniDocPlt)), {postprocess_warnings(CWarns ++ ModWarns, Codeserver), dialyzer_plt:restore_full_plt(MiniPlt, Plt), dialyzer_plt:restore_full_plt(MiniDocPlt, DocPlt)}. get_warnings_from_modules(Mods, State, DocPlt) -> #st{callgraph = Callgraph, codeserver = Codeserver, - no_warn_unused = NoWarnUnused, plt = Plt, - timing_server = TimingServer} = State, - Init = {Codeserver, Callgraph, NoWarnUnused, Plt, DocPlt}, + plt = Plt, timing_server = TimingServer} = State, + Init = {Codeserver, Callgraph, Plt, DocPlt}, dialyzer_coordinator:parallel_job(warnings, Mods, Init, TimingServer). --spec collect_warnings(module(), warnings_init_data()) -> [dial_warning()]. +-spec collect_warnings(module(), warnings_init_data()) -> [raw_warning()]. -collect_warnings(M, {Codeserver, Callgraph, NoWarnUnused, Plt, DocPlt}) -> +collect_warnings(M, {Codeserver, Callgraph, Plt, DocPlt}) -> ModCode = dialyzer_codeserver:lookup_mod_code(M, Codeserver), Records = dialyzer_codeserver:lookup_mod_records(M, Codeserver), Contracts = dialyzer_codeserver:lookup_mod_contracts(M, Codeserver), AllFuns = collect_fun_info([ModCode]), %% Check if there are contracts for functions that do not exist - Warnings1 = + Warnings1 = dialyzer_contracts:contracts_without_fun(Contracts, AllFuns, Callgraph), {Warnings2, FunTypes} = - dialyzer_dataflow:get_warnings(ModCode, Plt, Callgraph, - Records, NoWarnUnused), + dialyzer_dataflow:get_warnings(ModCode, Plt, Callgraph, Codeserver, + Records), Attrs = cerl:module_attrs(ModCode), Warnings3 = dialyzer_behaviours:check_callbacks(M, Attrs, Records, Plt, Codeserver), @@ -197,17 +193,19 @@ postprocess_warnings(RawWarnings, Codeserver) -> postprocess_dataflow_warns([], _Callgraph, WAcc, Acc) -> lists:reverse(Acc, WAcc);
