From 1645ca498679a555452dd201f8b636cc23c44b03 Mon Sep 17 00:00:00 2001 From: Klaus Aehlig Date: Tue, 26 Nov 2024 10:35:29 +0100 Subject: Add a library computing, in memory, a git tree from a stage Computed roots are given as the artifacts stage of a target. However, to be usable as a root, we need the git tree identifier of that root. Therefore, add a library doing this computation, avoiding file-system operations whenever possible. --- src/buildtool/computed_roots/artifacts_root.hpp | 34 +++++++++++++++++++++++++ 1 file changed, 34 insertions(+) create mode 100644 src/buildtool/computed_roots/artifacts_root.hpp (limited to 'src/buildtool/computed_roots/artifacts_root.hpp') diff --git a/src/buildtool/computed_roots/artifacts_root.hpp b/src/buildtool/computed_roots/artifacts_root.hpp new file mode 100644 index 00000000..6ed727fa --- /dev/null +++ b/src/buildtool/computed_roots/artifacts_root.hpp @@ -0,0 +1,34 @@ +// Copyright 2024 Huawei Cloud Computing Technology Co., Ltd. +// +// Licensed under the Apache License, Version 2.0 (the "License"); +// you may not use this file except in compliance with the License. +// You may obtain a copy of the License at +// +// http://www.apache.org/licenses/LICENSE-2.0 +// +// Unless required by applicable law or agreed to in writing, software +// distributed under the License is distributed on an "AS IS" BASIS, +// WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied. +// See the License for the specific language governing permissions and +// limitations under the License. + +#ifndef INCLUDED_SRC_BUILDTOOL_COMPUTED_ROOT_ARTIFACTS_ROOT_HPP +#define INCLUDED_SRC_BUILDTOOL_COMPUTED_ROOT_ARTIFACTS_ROOT_HPP + +#include +#include + +#include "src/buildtool/build_engine/expression/expression_ptr.hpp" +#include "src/buildtool/multithreading/async_map_consumer.hpp" + +/// \brief Compute to the git tree identifier, as hex string, corresponding to +/// an artifact stage; return std::nullopt in case of errors +/// \param stage Expression pointer supposed to represent a map from logical +/// paths to known artifacts +/// \param logger Logger to report problems; will be called with the fatal +/// property in case of error +auto ArtifactsRoot(ExpressionPtr const& stage, + AsyncMapConsumerLoggerPtr const& logger) + -> std::optional; + +#endif -- cgit v1.2.3
