From 9b291d454b059977639db26c847af4e835cda0c3 Mon Sep 17 00:00:00 2001 From: nsfisis Date: Sat, 18 Jul 2026 18:03:57 +0900 Subject: refactor(downloader): take &self across the downloader hierarchy Concurrent package operations call into the same downloader instances through Rc>; with &mut self methods every call holds a RefMut across its awaits, which panics with 'already mutably borrowed' the moment two operations overlap. This is groundwork for fanning out InstallationManager's download/install loops (same rework HttpDownloader/CurlDownloader already got). - DownloaderInterface/ChangeReportInterface/ArchiveDownloader/ VcsDownloader methods now take &self; as_change_report_interface returns &dyn instead of &mut dyn. - Implementors move their genuinely mutable state behind cells: FileDownloader.additional_cleanup_paths, the archive downloaders' cleanup_executed, ZipDownloader.zip_archive_object, VcsDownloaderBase.has_cleaned_changes, GitDownloader's stash/discard/ cache maps and GitUtil, SvnDownloader.cache_credentials, PerforceDownloader.perforce. FileDownloader.io gains a RefCell layer so get_local_changes can keep PHP's NullIO swap under &self. - ProcessExecutor::execute_async now returns a future that captures everything up front instead of borrowing the executor, and call sites build the future before awaiting, so no borrow on the shared executor is held while a subprocess runs. - Filesystem::remove_directory_async becomes remove_directory_async_via taking the Rc handle: the Filesystem is only borrowed for the sync head/tail, never across the rm subprocess await (sync borrow_mut users like rename/ensure_directory_exists would otherwise collide). - DownloadManager async call sites hold shared borrows only.
