From c2e699ab9d032ac91eb7bf344448c5b85ce37fb6 Mon Sep 17 00:00:00 2001 From: Adrian Blumer Date: Thu, 5 Nov 2026 16:44:54 +0100 Subject: [PATCH 1/5] feat(config)!: make the default list of sources from three variables The default list of sources came from TIMENET_HOME and TIMENET_REGISTRY. TIMENET_REGISTRY had two meanings: a URL was the registry after the local registry, and a local path was the local registry itself. Downloads went to the storage folder and builds to the registry folder, both under ~/.cache/timenet, where tools delete files without asking. Now each variable sets one thing. TIMENET_LOCAL_REGISTRY places the local registry, TIMENET_REMOTE_REGISTRY names the registry after it, and TIMENET_AUTO_BUILD puts the installed connectors last. default_sources() reads them at call time, and its arguments override them. default_local_registry() returns the local registry alone, and the first entry of the list is always that local registry. The local registry lies in ~/.timenet/registry, outside ~/.cache, because it holds builds. TIMENET_CACHE keeps ~/.cache/timenet for files that a build or a read can make again: the raw downloads in downloads/ and the control databases in control/. settings() raises TimeFValidationError for an empty or blank path or URL and for another invalid value, and the message names the variable. It loads the settings once, from the arguments merged over the variables, so an argument replaces an invalid variable. open_registry(), RemoteRegistry and S3Registry no longer take cache_dir=, and a remote registry reads only its own files. The planner alone decides where a release is read from. It resolves each release and each payload source through the list, and the local registry comes first in the default list. So a release in the local registry is read there, and the remote registry gets no request for it. BaseRegistry.local_root goes away, and LocalRegistry.root names the folder of a local registry. When TimeNet creates the downloads or the control folder of the cache, it writes a CACHEDIR.TAG marker file into it. It does not mark a folder that exists already. After a build, the engine deletes the raw downloads of the dataset only if the downloads folder holds the marker. The timenet cache group is now timenet local, for the local files of TimeNet. timenet local info shows the path and the size of the cache and of the local registry. timenet local cache info shows the cache alone. timenet local cache clear deletes the raw source files and the control databases of the cache, and only a folder that holds the marker. It keeps a folder without the marker, for example a folder of the user, and names it in a warning. A symlinked folder with the marker is unlinked, and its target stays. timenet local clear deletes the cache and each release directory in the local registry, but no other file. Each clear asks first, and --yes skips the question. In timenet.cache, clear_cache(cache_dir, local_registry=) deletes the folders of the cache, and clear_releases(store) deletes the releases through LocalRegistry.releases() and LocalRegistry.remove_release(). Before it deletes anything, clear_cache() runs one private check. It refuses a cache directory that is the home folder or a folder above it. With TIMENET_CACHE=~ on macOS, the downloads folder of the cache would be ~/Downloads. It also refuses a local registry and a folder to delete that are the same folder or that lie in each other, because the local registry holds builds. The check compares the folders on disk by device and inode number, not the text of the paths, so it also sees a symlink, or a name in other letter case on a volume that ignores case. A build that removes its raw downloads runs the same check before its first download. timenet local clear clears the cache first, so a failed check deletes no release. download() uses the same comparison to tell whether a registry in the list is the local registry. The build CLI and timenet_connectors.build() write to the local registry when no output is given. An empty or blank --out is an error, not the current directory. This glue stays until the producer API replaces them. The root conftest.py now gives each test its own local registry, remote registry and cache through the new variables instead of TIMENET_HOME. BREAKING CHANGE: TIMENET_HOME, TIMENET_STORAGE and TIMENET_REGISTRY are gone. TIMENET_LOCAL_REGISTRY (default ~/.timenet/registry) places the local registry, TIMENET_REMOTE_REGISTRY (default timenet://) names the registry after it, and TIMENET_AUTO_BUILD (default true) puts the installed connectors last. TIMENET_CACHE defaults to ~/.cache/timenet, and raw downloads lie under its downloads folder. default_registry_path() is gone. The timenet cache group is now timenet local, with info, clear, cache info and cache clear. clear_cache() takes the cache directory and local_registry=, and deletes only the folders of the cache. clear_releases() deletes the releases in the local registry. open_registry(), RemoteRegistry and S3Registry no longer take cache_dir=, and a remote registry reads no local copy. To read a local copy, put its LocalRegistry in the list of sources before the remote registry. BaseRegistry.local_root and LocalRegistry.local_root are gone. Use LocalRegistry.root.
