Build the explorer (Task 3.3) - #68
Merged
Merged
Conversation
Adds the explorer built-in: a lazy-loading directory tree over workspace.fs.readdir/watch, create/rename/delete via showInputBox/ showQuickPick, real .gitignore-aware visibility (batched git check-ignore when available, a glob-matcher fallback otherwise), explorer.showHidden, the explorerFocus context key, and ctrl+shift+e. Along the way: FileSystem gains delete/rename/mkdir; tecode.ui.Tree gains controlled expansion, keyboard nav, and focus tracking; the shared ignore-aware walk now also backs command-palette's ctrl+p.

Inline comments:
In `@packages/api/src/namespaces.ts`:
- Around line 114-119: Update the implementation of the rename method to
atomically reject an already-existing newUri instead of allowing
node:fs/promises.rename to replace it, while preserving the existing failure
behavior for missing oldUri and permission errors. Add a regression test
covering an existing destination and verify that the destination contents remain
unchanged.
In `@packages/builtin/explorer/index.ts`:
- Around line 92-100: packages/builtin/explorer/index.ts の 92-100 行では
validateEntryName にドットおよびドット二つの名前を拒否する検証を追加する。127-136 行では joinChildUri
を呼ぶ前に検証結果を確認し、無効な名前なら処理を中止する。196-203 行でも rename の joinChildUri 呼び出し前に同じ検証を適用する。
In `@packages/builtin/explorer/store.ts`:
- Around line 238-247: Update reload around childrenByDir.set and the related
parentByUri, relativeDirByUri, and directoryUris caches to reconcile old and new
children: remove metadata for removed or type-changed entries and all cached
descendants beneath them. If the current selection is removed, reset it to the
affected parent or root using the existing selection state and reload helpers.
- Around line 208-248: Update reload to track a per-directory generation or
request token that advances when each reload starts, and before applying results
verify the token is still current. Only the latest reload for a directory may
update childrenByDir and related state such as URI mappings, directory tracking,
and fireChange; discard stale results from earlier reloads after either awaited
operation.
In `@packages/builtin/shared/gitignoreMatcher.ts`:
- Around line 44-50: Update escapeRegexLiteral to include ? among the regex
metacharacters escaped in the character class, ensuring question marks remain
literal while existing wildcard handling is unchanged.
In `@packages/builtin/shared/gitRunner.test.ts`:
- Around line 1-9: Update the test suite around the real GitRunner
implementation to evaluate isAvailable() with top-level await, store the result
in a hasGit flag, and wrap the suite with describe.skipIf(!hasGit). Preserve the
existing assertions, while allowing environments without a git binary to skip
the suite instead of failing.
In `@packages/builtin/shared/gitRunner.ts`:
- Around line 118-130: Update the git check-ignore invocation to use -z, write
absolutePaths joined with NUL separators and a trailing NUL, and parse output by
splitting on NUL without trimming path contents so paths containing whitespace
or newlines remain matchable.
In `@packages/builtin/shared/ignore.ts`:
- Around line 177-190: Update the git-backed filtering flow around
isGitAvailable and gitRunner.checkIgnore so workspaces outside a Git repository
fall back to the existing glob-based ignore matching. Detect repository
membership once per workspace root, or otherwise distinguish an unavailable Git
ignore decision from an empty ignored set; preserve the current Git path for
repository workspaces and the existing fallback behavior when Git is
unavailable.

Fixes 9 review findings from the explorer build (Task 3.3, Req 11.2): - fileSystem.ts: rename() now probes the destination with lstat and rejects if it already exists, instead of silently replacing it (POSIX rename(2) semantics on Linux). - explorer/store.ts reload(): diffs old vs. new children on every reload; a removed or type-changed entry purges its own metadata and every cached descendant, and resets selection to the affected parent if the current selection was purged. - explorer/store.ts reload(): per-directory generation counter so an earlier-started reload of the same directory can no longer clobber a later one that resolves first. - explorer/index.ts: validateEntryName rejects "." and "..", and both the create and rename command handlers re-check right at the joinChildUri call site (not just via showInputBox's validateInput, which a programmatic command invocation can bypass) — closes a path traversal via joinChildUri's unescaped-dot encodeURIComponent behavior. - gitignoreMatcher.ts: escape "?" as a regex literal so patterns like "foo?.log" don't compile "?" into a quantifier. - gitRunner.test.ts: the real-git-CLI suite now checks isAvailable() once up front and skips itself on git-less CI images instead of asserting isAvailable() === true unconditionally. - gitRunner.ts checkIgnore(): use "git check-ignore -z --stdin" so paths are NUL-separated end to end, keeping paths with spaces or newlines matchable. - gitRunner.ts/ignore.ts: added GitRunner.isRepository() and use it to detect a non-repo workspace even when git itself is installed, so the .gitignore glob fallback still applies instead of silently disabling ignore filtering. - explorer/index.test.tsx: selectViaTree now destroys its temporary testRender mount, matching its own TSDoc.
