From: Mikko Rasa Date: Wed, 8 May 2013 09:36:22 +0000 (+0300) Subject: Store problems at their source rather than globally X-Git-Url: http://git.tdb.fi/?a=commitdiff_plain;h=0d95fee118a3fcd78f153dca5721d9fe19b6f6bf;p=builder.git Store problems at their source rather than globally This allows finer granularity in determining whether problems are preventing a build. In some cases it may be desirable to build just one component of a package, even if others have problems. --- diff --git a/source/binary.cpp b/source/binary.cpp index 9f0bfcd..e7b5e81 100644 --- a/source/binary.cpp +++ b/source/binary.cpp @@ -33,6 +33,7 @@ void Binary::find_dependencies() list queue; list dep_libs; + set missing_libs; queue.push_back(component); while(!queue.empty()) { @@ -56,8 +57,8 @@ void Binary::find_dependencies() else dep_libs.push_back(lib); } - else - builder.problem(package->get_name(), format("Couldn't find library %s for %s", *i, name)); + else if(missing_libs.insert(*i).second) + problems.push_back(format("Required library %s not found", *i)); } } diff --git a/source/binarypackage.cpp b/source/binarypackage.cpp index 22a4154..4c53821 100644 --- a/source/binarypackage.cpp +++ b/source/binarypackage.cpp @@ -72,7 +72,8 @@ void BinaryPackage::do_prepare() if(base_path.empty()) { - builder.problem(name, "Cannot locate files"); + // TODO report which files were not found + problems.push_back("Cannot locate files"); return; } diff --git a/source/builder.cpp b/source/builder.cpp index bbb95b6..81f4d8e 100644 --- a/source/builder.cpp +++ b/source/builder.cpp @@ -98,9 +98,57 @@ void Builder::set_logger(const Logger *l) logger = (l ? l : &default_logger); } -void Builder::problem(const string &p, const string &d) +list Builder::collect_problems() const { - problems.push_back(Problem(p, d)); + list problems; + set broken_packages; + set broken_components; + set broken_tools; + + const BuildGraph::TargetMap &targets = build_graph.get_targets(); + for(BuildGraph::TargetMap::const_iterator i=targets.begin(); i!=targets.end(); ++i) + if(i->second->is_broken()) + { + const list &tgt_problems = i->second->get_problems(); + for(list::const_iterator j=tgt_problems.begin(); j!=tgt_problems.end(); ++j) + problems.push_back(format("%s: %s", i->second->get_name(), *j)); + + const Package *package = i->second->get_package(); + if(package && !package->get_problems().empty()) + broken_packages.insert(package); + + const Component *component = i->second->get_component(); + if(component && !component->get_problems().empty()) + broken_components.insert(component); + + const Tool *tool = i->second->get_tool(); + if(tool && !tool->get_problems().empty()) + broken_tools.insert(tool); + } + + // TODO Sort components after their packages, and targets last + for(set::const_iterator i=broken_packages.begin(); i!=broken_packages.end(); ++i) + { + const list &pkg_problems = (*i)->get_problems(); + for(list::const_iterator j=pkg_problems.begin(); j!=pkg_problems.end(); ++j) + problems.push_back(format("%s: %s", (*i)->get_name(), *j)); + } + + for(set::const_iterator i=broken_components.begin(); i!=broken_components.end(); ++i) + { + const list &comp_problems = (*i)->get_problems(); + for(list::const_iterator j=comp_problems.begin(); j!=comp_problems.end(); ++j) + problems.push_back(format("%s/%s: %s", (*i)->get_package().get_name(), (*i)->get_name(), *j)); + } + + for(set::const_iterator i=broken_tools.begin(); i!=broken_tools.end(); ++i) + { + const list &tool_problems = (*i)->get_problems(); + for(list::const_iterator j=tool_problems.begin(); j!=tool_problems.end(); ++j) + problems.push_back(format("%s: %s", (*i)->get_tag(), *j)); + } + + return problems; } void Builder::load_build_file(const FS::Path &fn, const Config::InputOptions *opts, bool all) diff --git a/source/builder.h b/source/builder.h index 4c78a3d..3004ed2 100644 --- a/source/builder.h +++ b/source/builder.h @@ -12,7 +12,6 @@ #include "config.h" #include "logger.h" #include "packagemanager.h" -#include "problem.h" #include "target.h" #include "toolchain.h" #include "virtualfilesystem.h" @@ -46,9 +45,6 @@ private: void package(const std::string &); }; -public: - typedef std::list ProblemList; - private: typedef std::map BuildTypeMap; @@ -64,7 +60,6 @@ private: Logger default_logger; const Logger *logger; - ProblemList problems; Msp::FS::Path prefix; Msp::FS::Path tempdir; @@ -93,8 +88,7 @@ public: void set_logger(const Logger *); const Logger &get_logger() const { return *logger; } - void problem(const std::string &, const std::string &); - const ProblemList &get_problems() const { return problems; } + std::list collect_problems() const; /** Loads a build file.
