Routing-Key: inbox-route/I_kwDOSUhdos8AAAABTSySyw

A plain-directory patch source (e.g. source = "~/dotfiles") expands to dir/**/* and copied the whole tree with no excludes or size cap.

  • Add default excludes for common VCS and dependency directories (.git, .hg, .svn, CVS, .jj, node_modules).
  • Add a 100 MiB total-size cap that fails activation instead of copying silently.
  • Stop emitting a false "dropping" warning for a symlinked source directory: the OS resolves the symlink during path resolution, so walkdir traverses it even with follow_symlinks off. The warning now fires only when the walk root is a symlink to a file.
  • Document the directory form, its excludes, and the size cap in docs/reference/loadouts.md.

Verification

  • cargo fmt --all --check --manifest-path target/Cargo.toml
  • cargo clippy -p sessions --locked --manifest-path target/Cargo.toml -- -D warnings
  • cargo build --workspace --locked --manifest-path target/Cargo.toml
  • cargo test -p sessions --locked --manifest-path target/Cargo.toml (510 lib + 40 integration + 5 doctests pass)

Summary by CodeRabbit

  • New Features
    • Plain-directory sources and $LOADOUT_ROOT now recursively include files from their directory trees, excluding common version-control and dependency directories.
  • Bug Fixes
    • Activation fails when copying a plain-directory source would exceed 100 MiB. Symlink-to-file walk roots are skipped with a warning when symlink following is disabled.
  • Documentation
    • Clarified how plain-directory sources expand, which directories are skipped, how to use a glob to narrow copied files, and the size limit.

A plain-directory patch source (e.g. `source = "~/dotfiles"`) expands
to `dir/**/*` and copied the whole tree with no excludes or size cap.

Add default excludes for common VCS and dependency directories
(`.git`, `.hg`, `.svn`, `CVS`, `.jj`, `node_modules`) and a 100 MiB
total-size cap that fails activation instead of copying silently.

Also stop emitting a false "dropping" warning for a symlinked source
directory: the OS resolves the symlink during path resolution, so
walkdir traverses it even with `follow_symlinks` off. The warning now
fires only when the walk root is a symlink to a file.

Document the directory form, its excludes, and the size cap in
`docs/reference/loadouts.md`.

📝 Walkthrough

Walkthrough

Plain-directory patch sources are identified during expansion and copied recursively during enumeration. Enumeration excludes selected directories, enforces a 100 MiB size limit, and handles symlinks. Documentation describes the behavior, including $LOADOUT_ROOT alone.

Changes

Plain-directory patch handling

Layer / File(s) Summary
Track plain-directory sources
crates/sessions/src/core/expansion.rs, crates/sessions/src/core/compose.rs
Expansion returns a flag for existing non-glob directories. Patch composition stores the flag with each expanded source.
Filter and bound directory copies
crates/sessions/src/core/primitives.rs, crates/sessions/src/core/enumerate.rs, docs/reference/loadouts.md
Enumeration excludes .git, .hg, .svn, CVS, .jj, and node_modules. It enforces a 100 MiB cumulative size limit and reports size or metadata errors. Tests cover exclusions, symlinked directories, and the size cap. Documentation describes plain-directory and $LOADOUT_ROOT copies.

A rabbit checked the folders in the spring,
Skipped the trees that hid the versioning,
Counted every byte along the way,
And kept the oversize patch at bay,
Then hopped through links to greet the day.

Review comments at @crates/sessions/src/core/enumerate.rs:
- Line 263: Update the enumeration path’s metadata handling to propagate errors
in
8000
stead of discarding them with `.ok()?`, so matched files cannot be emitted
without their size being measured; ensure directory-traversal errors also fail
closed rather than silently skipping files.
- Line 133: Carry the plain-directory classification through
`ExpandedProvenancedPatch` into `enumerate_patch_files`, and apply
`is_default_excluded_dir` and `accumulate_size` only to sources classified as
plain directories. Preserve explicit glob and literal-file behavior without
these directory-only safeguards.

Review comments at @docs/reference/loadouts.md:
- Around line 246-247: Update the `$LOADOUT_ROOT` example in the loadout source
documentation to explain that, when the directory exists, it is a plain
directory source that copies its whole tree. Remove the claim that it matches
nothing, and clarify that `$LOADOUT_ROOT/**/*` is only needed for an explicit
glob.
