Adds a session_directory extension event that fires before session manager
creation, allowing extensions to customize the session directory path based
on cwd, git branch, or other context.
- Extensions can return a custom sessionDir in the event handler
- CLI --session-dir flag takes precedence over extension-provided paths
- If multiple extensions return a sessionDir, the last one wins
- Enables implementing branch-based sessions as an extension instead of core feature
This provides the extension point needed to implement git branch-based
session directories without adding the complexity to core.
Closes#1729
Add manual retry loop (10 attempts, 20ms delay) around lockfile.lockSync()
in FileAuthStorageBackend and FileSettingsStorage. Previously, concurrent
pi processes would fail immediately on ELOCKED, causing auth.json to load
as empty and surfacing misleading 'No API key found' errors.
fixes#1871
Add configurable initial filter mode for the session tree navigator.
Users who always switch to a specific filter (e.g. no-tools via Ctrl+T)
can now set it as default in settings.
Same pattern as doubleEscapeAction (#404). Filter infra from #747.
The previous fix (83b57924) replaced require.resolve() with bare
specifier fallbacks to avoid ERR_PACKAGE_PATH_NOT_EXPORTED for ESM-only
packages like pi-ai. However, bare specifiers are not valid jiti alias
targets, breaking extension loading in global npm installs.
Use import.meta.resolve() as the fallback instead. It respects the
"import" exports condition and returns a real file path.
When enabled, /tree navigation skips the 'Summarize branch?' prompt and
defaults to no summary, reducing friction for users who never want branch
summaries.
Closes#1791
Messages submitted while a branch summary was being generated were
processed immediately instead of being queued. This happened because
isCompacting only checked compaction abort controllers, not the branch
summary abort controller.
Include _branchSummaryAbortController in the isCompacting getter so all
existing guards (message queueing, reload blocking) also apply during
branch summarization.
createBranchedSession() wrote the file and set flushed=true even when the
branched path had no assistant message. The next _persist() call saw no
assistant, reset flushed=false, and the subsequent flush appended all
in-memory entries to the already-populated file, duplicating the header
and entries.
Fix: defer file creation when the branched path has no assistant message,
matching the newSession() contract. _persist() creates the file on the
first assistant response.
closes#1672
When resolving --model zai/glm-5, the resolver now correctly interprets
'zai' as the provider and 'glm-5' as the model id, rather than matching
a vercel-ai-gateway model whose id is literally 'zai/glm-5'.
If the provider/model split fails to find a match, falls back to raw id
matching to still support OpenRouter-style ids like 'openai/gpt-4o:extended'.
