From d15db4b1fc988736b08c092d000ca1d1ff686975 Mon Sep 17 00:00:00 2001 From: Jonathan Schoeller Date: Mon, 1 Jun 2020 18:05:15 +1000 Subject: [PATCH 1/2] refactor: Fix unreachable code in init arg checks Building with -Wunreachable-code-loop-increment causes a warning due to always returning on the first iteration of the loop that outputs errors on invalid args. Collect all errors, and output them in a single error message after the loop completes, resolving the warning and avoiding popup hell by outputting a seperate message for each error. --- src/init.cpp | 16 +++++++++++++--- src/util/translation.h | 5 +++++ test/functional/feature_config_args.py | 2 +- 3 files changed, 19 insertions(+), 4 deletions(-) diff --git a/src/init.cpp b/src/init.cpp index 37e62512955..0ff89eb8167 100644 --- a/src/init.cpp +++ b/src/init.cpp @@ -964,17 +964,27 @@ bool AppInitParameterInteraction() // also see: InitParameterInteraction() - // Warn if network-specific options (-addnode, -connect, etc) are + // Error if network-specific options (-addnode, -connect, etc) are // specified in default section of config file, but not overridden // on the command line or in this network's section of the config file. std::string network = gArgs.GetChainName(); + bilingual_str errors; for (const auto& arg : gArgs.GetUnsuitableSectionOnlyArgs()) { - return InitError(strprintf(_("Config setting for %s only applied on %s network when in [%s] section."), arg, network, network)); + errors += strprintf(_("Config setting for %s only applied on %s network when in [%s] section.") + Untranslated("\n"), arg, network, network); + } + + if (!errors.empty()) { + return InitError(errors); } // Warn if unrecognized section name are present in the config file. + bilingual_str warnings; for (const auto& section : gArgs.GetUnrecognizedSections()) { - InitWarning(strprintf(Untranslated("%s:%i ") + _("Section [%s] is not recognized."), section.m_file, section.m_line, section.m_name)); + warnings += strprintf(Untranslated("%s:%i ") + _("Section [%s] is not recognized.") + Untranslated("\n"), section.m_file, section.m_line, section.m_name); + } + + if (!warnings.empty()) { + InitWarning(warnings); } if (!fs::is_directory(GetBlocksDir())) { diff --git a/src/util/translation.h b/src/util/translation.h index 268bcf30a72..695d6dac965 100644 --- a/src/util/translation.h +++ b/src/util/translation.h @@ -23,6 +23,11 @@ struct bilingual_str { translated += rhs.translated; return *this; } + + bool empty() const + { + return original.empty(); + } }; inline bilingual_str operator+(bilingual_str lhs, const bilingual_str& rhs) diff --git a/test/functional/feature_config_args.py b/test/functional/feature_config_args.py index 1a7c6562749..a4dc455d571 100755 --- a/test/functional/feature_config_args.py +++ b/test/functional/feature_config_args.py @@ -71,7 +71,7 @@ class ConfArgsTest(BitcoinTestFramework): with open(inc_conf_file2_path, 'w', encoding='utf-8') as conf: conf.write('[testnet]\n') self.restart_node(0) - self.nodes[0].stop_node(expected_stderr='Warning: ' + inc_conf_file_path + ':1 Section [testnot] is not recognized.' + os.linesep + 'Warning: ' + inc_conf_file2_path + ':1 Section [testnet] is not recognized.') + self.nodes[0].stop_node(expected_stderr='Warning: ' + inc_conf_file_path + ':1 Section [testnot] is not recognized.' + os.linesep + inc_conf_file2_path + ':1 Section [testnet] is not recognized.') with open(inc_conf_file_path, 'w', encoding='utf-8') as conf: conf.write('') # clear From eea81146571480b2acd12c8cd7f36b04d056c47f Mon Sep 17 00:00:00 2001 From: Jonathan Schoeller Date: Tue, 2 Jun 2020 06:24:10 +1000 Subject: [PATCH 2/2] build: Enable unreachable-code-loop-increment Enable unreachable-code-loop-increment and treat as error. refs: #19015 --- configure.ac | 2 ++ 1 file changed, 2 insertions(+) diff --git a/configure.ac b/configure.ac index 34b8354cdac..69553536938 100644 --- a/configure.ac +++ b/configure.ac @@ -391,6 +391,7 @@ if test "x$enable_werror" = "xyes"; then dnl https://gcc.gnu.org/bugzilla/show_bug.cgi?id=78010 AX_CHECK_COMPILE_FLAG([-Werror=suggest-override],[ERROR_CXXFLAGS="$ERROR_CXXFLAGS -Werror=suggest-override"],,[[$CXXFLAG_WERROR]], [AC_LANG_SOURCE([[struct A { virtual void f(); }; struct B : A { void f() final; };]])]) + AX_CHECK_COMPILE_FLAG([-Werror=unreachable-code-loop-increment],[ERROR_CXXFLAGS="$ERROR_CXXFLAGS -Werror=unreachable-code-loop-increment"],,[[$CXXFLAG_WERROR]]) fi if test "x$CXXFLAGS_overridden" = "xno"; then @@ -410,6 +411,7 @@ if test "x$CXXFLAGS_overridden" = "xno"; then AX_CHECK_COMPILE_FLAG([-Wsign-compare],[WARN_CXXFLAGS="$WARN_CXXFLAGS -Wsign-compare"],,[[$CXXFLAG_WERROR]]) AX_CHECK_COMPILE_FLAG([-Wsuggest-override],[WARN_CXXFLAGS="$WARN_CXXFLAGS -Wsuggest-override"],,[[$CXXFLAG_WERROR]], [AC_LANG_SOURCE([[struct A { virtual void f(); }; struct B : A { void f() final; };]])]) + AX_CHECK_COMPILE_FLAG([-Wunreachable-code-loop-increment],[WARN_CXXFLAGS="$WARN_CXXFLAGS -Wunreachable-code-loop-increment"],,[[$CXXFLAG_WERROR]]) dnl Some compilers (gcc) ignore unknown -Wno-* options, but warn about all dnl unknown options if any other warning is produced.
