The initial version of SymbolLocatorSymStore supported servers only on local paths. This patch extends it to HTTP/HTTPS end-points. For that to work on Windows, we add a WinHTTP-based HTTP client backend in LLVM next to the existing CURL-based implementation. We don't add a HTTP server implementation, because there is no use right now. Test coverage for the LLVM part is built on llvm-debuginfod-find and works server-less, since it checks textual output of request headers. The existing CURL-based implementation uses the same approach. The LLDB API test for the specific SymbolLocatorSymStore feature spawns a HTTP server from Python. To keep the size of this patch within reasonable limits, the initial implementation of the SymbolLocatorSymStore feature is dump: There is no caching, no verification of downloaded files and no protection against file corruptions. We use a local implementation of LLVM's HTTPResponseHandler, but should think about extracting and reusing Debuginfod's StreamedHTTPResponseHandler in the future. The goal of this patch is a basic working implementation that is testable in isolation. We will iterate on it to improve it further. This should be fine since downloading from SymStores is not default-enabled yet. Users have to set their server URLs explicitly. --------- Co-authored-by: Alexandre Ganea <aganea@havenstudios.com>
The LLVM Compiler Infrastructure
Welcome to the LLVM project!
This repository contains the source code for LLVM, a toolkit for the construction of highly optimized compilers, optimizers, and run-time environments.
The LLVM project has multiple components. The core of the project is itself called "LLVM". This contains all of the tools, libraries, and header files needed to process intermediate representations and convert them into object files. Tools include an assembler, disassembler, bitcode analyzer, and bitcode optimizer.
C-like languages use the Clang frontend. This component compiles C, C++, Objective-C, and Objective-C++ code into LLVM bitcode -- and from there into object files, using LLVM.
Other components include: the libc++ C++ standard library, the LLD linker, and more.
