Adds a test case to `settings.test.ts` to specifically verify
the correct resolution of multiple environment variables concatenated
within a single string value (e.g., ${HOST}:${PORT} ).
Refactors the `resolveEnvVarsInObject` function in settings to
explicitly handle primitive types (null, undefined, boolean, number)
at the beginning of the function. This clarifies the logic for
subsequent string, array, and object processing.
This commit introduces the ability to use system environment variables
within the settings files (e.g., `settings.json`). Users can now
reference environment variables using the `${VAR_NAME}` syntax.
This enhancement improves security and flexibility, particularly
for configurations like MCP server settings, which often require
sensitive tokens.
Previously, to configure an MCP server, a token might be directly
embedded:
```json
"mcpServers": {
"github": {
"env": {
"GITHUB_PERSONAL_ACCESS_TOKEN": "pat_abc123"
}
// ...
}
}
```
With this change, the same configuration can securely reference an
environment variable:
```json
"mcpServers": {
"github": {
"env": {
"GITHUB_PERSONAL_ACCESS_TOKEN": "${GITHUB_PERSONAL_ACCESS_TOKEN}"
}
// ...
}
}
```
This allows users to avoid storing secrets directly in configuration files.
Address multiple possible memory leaks found bystatic analysis of the codebase. The primary source of the leaks was event listeners on child processes and global objects that were not being properly removed, potentially causing their closures to be retained in memory indefinitely particularly for processes that did not exit.
There are two commits. A larger one made by gemini CLI and a smaller one by me to make sure we always disconnect child processes as part of the cleanup methods. These changes may not actually fix any leaks but do look like reasonable defensive coding to avoid leaking event listeners or child processes.
The following files were fixed:
This is Gemini's somewhat overconfident description of what it did.
packages/core/src/tools/shell.ts: Fixed a leak where an abortSignal listener was not being reliably removed.
packages/cli/src/utils/readStdin.ts: Fixed a significant leak where listeners on process.stdin were never removed.
packages/cli/src/utils/sandbox.ts: Fixed leaks in the imageExists and pullImage helper functions where listeners on spawned child processes were not being removed.
packages/core/src/tools/grep.ts: Fixed three separate leaks in the isCommandAvailable check and the git grep and system grep strategies due to un-removed listeners on child processes.
packages/core/src/tools/tool-registry.ts: Corrected a leak in the execute method of the DiscoveredTool class where listeners on the spawned tool process were not being removed.
# Add .gitignore-Aware File Filtering to gemini-cli
This pull request introduces .gitignore-based file filtering to the gemini-cli, ensuring that git-ignored files are automatically excluded from file-related operations and suggestions throughout the CLI. The update enhances usability, reduces noise from build artifacts and dependencies, and provides new configuration options for fine-tuning file discovery.
Key Improvements
.gitignore File Filtering
All @ (at) commands, file completions, and core discovery tools now honor .gitignore patterns by default.
Git-ignored files (such as node_modules/, dist/, .env, and .git) are excluded from results unless explicitly overridden.
The behavior can be customized via a new fileFiltering section in settings.json, including options for:
Turning .gitignore respect on/off.
Adding custom ignore patterns.
Allowing or excluding build artifacts.
Configuration & Documentation Updates
settings.json schema extended with fileFiltering options.
Documentation updated to explain new filtering controls and usage patterns.
Testing
New and updated integration/unit tests for file filtering logic, configuration merging, and edge cases.
Test coverage ensures .gitignore filtering works as intended across different workflows.
Internal Refactoring
Core file discovery logic refactored for maintainability and extensibility.
Underlying tools (ls, glob, read-many-files) now support git-aware filtering out of the box.

- Introduces a suite of tests for the hook, covering various scenarios including:
- Successful tool execution
- Tool not found errors
- Errors during
- Errors during tool execution
- Tool confirmation (approved and cancelled) - (currently skipped)
- Live output updates - (currently skipped)
- Cancellation of tool calls (before execution and during approval) - (currently skipped)
- Execution of multiple tool calls
- Preventing scheduling while other calls are running - (currently skipped)
- Includes tests for the utility function to ensure correct mapping of tool call states to display objects.
- Mocks dependencies like , , and individual instances.
- Uses fake timers to control asynchronous operations.
Note: Some tests involving complex asynchronous interactions (confirmations, live output, cancellations) are currently skipped due to challenges in reliably testing these scenarios with the current setup. These will be addressed in future work.
This change introduces a small delay after the first Ctrl+C press, prompting the user to press Ctrl+C again to exit. This helps prevent accidental termination of the application.
- Added `exitOnCtrlC={false}` to the Ink render options in `gemini.tsx` to enable custom Ctrl+C handling.
- Implemented logic in `App.tsx` to:
- Display "Press Ctrl+C again to exit." for 2 seconds after the first Ctrl+C.
- Exit the application if Ctrl+C is pressed again during this period.
- Revert to normal operation if the second Ctrl+C is not pressed within the timeout.
- Defined a constant `CTRL_C_PROMPT_DURATION_MS` for the timeout duration.
- Consolidates consecutive model messages into a single message in the chat history.
- This prevents multiple model messages from being displayed in a row, improving readability.
- This may also address some instances of 500 errors that could have been caused by multiple, rapidly succeeding model messages.
- Adds tests for the new consolidation logic.
