* remote.meta.sync: materialize directory entries, including empty ones
Pull metadata by walking the remote tree one directory level at a time
with a delimiter, so subdirectories, including empty ones, are listed as
their own entries and created locally. The previous flat listing only
returned files, so empty remote directories never appeared locally and
non-empty ones only existed as filer-synthesized parents.
* remote.meta.sync: remove local metadata for entries deleted from remote
After reconciling each directory, drop local entries whose remote source
is gone: files are deleted outright, and a directory removed from the
remote is descended into so its remote-backed children are cleaned while
local-only entries are kept. remote.meta.sync exposes -delete (default
on) and remote.mount.buckets reconciles the same way; a plain
remote.mount stays additive.
* remote.meta.sync: reconcile type swaps and prune emptied directories
- when the remote swaps an entry's type (file <-> directory), drop the
stale local entry and recreate it with the right type; local-only
entries are left alone
- mark synced directories remote-backed and clean a directory removed
from the remote locally, deleting it once it holds no local-only
entries, instead of re-listing the missing remote path
- treat a differing remote size or mtime, not only a newer mtime, as a
change worth pulling
* feat(remote): add -noSync flag to skip upfront metadata pull on mount
Made-with: Cursor
* refactor(remote): split mount setup from metadata sync
Extract ensureMountDirectory for create/validate; call pullMetadata
directly when sync is needed. Caller controls sync step for -noSync.
Made-with: Cursor
* fix(remote): validate mount root when -noSync so bad bucket/creds fail fast
When -noSync is used, perform a cheap remote check (ListBuckets and
verify bucket exists) instead of skipping all remote I/O. Invalid
buckets or credentials now fail at mount time.
Made-with: Cursor
* test(remote): add TestRemoteMountNoSync for -noSync mount and persisted mapping
Made-with: Cursor
* test(remote): assert no upfront metadata after -noSync mount
After remote.mount -noSync, run fs.ls on the mount dir and assert empty
listing so the test fails if pullMetadata was invoked eagerly.
Made-with: Cursor
* fix(remote): propagate non-ErrNotFound lookup errors in ensureMountDirectory
Return lookupErr immediately for any LookupDirectoryEntry failure that
is not filer_pb.ErrNotFound, so only the not-found case creates the
entry and other lookup failures are reported to the caller.
Made-with: Cursor
* fix(remote): use errors.Is for ErrNotFound in ensureMountDirectory
Replace fragile strings.Contains(lookupErr.Error(), ...) with
errors.Is(lookupErr, filer_pb.ErrNotFound) before calling CreateEntry.
Made-with: Cursor
* fix(remote): use LookupEntry so ErrNotFound is recognised after gRPC
Raw gRPC LookupDirectoryEntry returns a status error, not the sentinel,
so errors.Is(lookupErr, filer_pb.ErrNotFound) was always false. Use
filer_pb.LookupEntry which normalises not-found to ErrNotFound so the
mount directory is created when missing.
Made-with: Cursor
* test(remote): ignore weed shell banner in TestRemoteMountNoSync fs.ls count
Exclude master/filer and prompt lines from entry count so the assertion
checks only actual fs.ls output for empty -noSync mount.
Made-with: Cursor
* fix(remote.mount): use 0755 for mount dir, document bucket-less early return
Made-with: Cursor
* feat(remote.mount): replace -noSync with -metadataStrategy=lazy|eager
- Add -metadataStrategy flag (eager default, lazy skips upfront metadata pull)
- Accept lazy/eager case-insensitively; reject invalid values with clear error
- Rename TestRemoteMountNoSync to TestRemoteMountMetadataStrategyLazy
- Add TestRemoteMountMetadataStrategyEager and TestRemoteMountMetadataStrategyInvalid
Made-with: Cursor
* fix(remote.mount): validate strategy and remote before creating mount directory
Move strategy validation and validateMountRoot (lazy path) before
ensureMountDirectory so that invalid strategies or bad bucket/credentials
fail without leaving orphaned directory entries in the filer.
* refactor(remote.mount): remove unused remote param from ensureMountDirectory
The remote *RemoteStorageLocation parameter was left over from the old
syncMetadata signature. Only remoteConf.Name is used inside the function.
* doc(remote.mount): add TODO for HeadBucket-style validation
validateMountRoot currently lists all buckets to verify one exists.
Note the need for a targeted BucketExists method in the interface.
* refactor(remote.mount): use MetadataStrategy type and constants
Replace raw string comparisons with a MetadataStrategy type and
MetadataStrategyEager/MetadataStrategyLazy constants for clarity
and compile-time safety.
* refactor(remote.mount): rename MetadataStrategy to MetadataCacheStrategy
More precisely describes the purpose: controlling how metadata is
cached from the remote, not metadata handling in general.
* fix(remote.mount): remove validateMountRoot from lazy path
Lazy mount's purpose is to skip remote I/O. Validating via ListBuckets
contradicts that, especially on accounts with many buckets. Invalid
buckets or credentials will surface on first lazy access instead.
* fix(test): handle shell exit 0 in TestRemoteMountMetadataStrategyInvalid
The weed shell process exits with code 0 even when individual commands
fail — errors appear in stdout. Check output instead of requiring a
non-nil error.
* test(remote.mount): remove metadataStrategy shell integration tests
These tests only verify string output from a shell process that always
exits 0 — they cannot meaningfully validate eager vs lazy behavior
without a real remote backend.
