Pull request overview
This PR adds support for infinite sessions with automatic context compaction and workspace persistence across all language SDKs (Python, Node.js, Go, and .NET). Sessions can now automatically manage context window limits through background compaction and persist state to workspace directories.
Changes:
- Added
InfiniteSessionConfigtype across all SDKs with configurable thresholds for background compaction and buffer exhaustion - Updated session objects to include
workspace_pathproperty that points to the session's persistent workspace directory - Modified create and resume session methods to accept infinite session configuration and return workspace paths
- Added comprehensive documentation with usage examples for all supported languages

- The function call references
Float64(0.95)but should becopilot.Float64(0.95)to be consistent with thecopilot.Bool(true)on line 284. This appears to be a missing package prefix.
BufferExhaustionThreshold: Float64(0.95), // Block at 95% until compaction completes

- Test compaction triggers with low thresholds (0.5%/1%) - Test session.usage_info events show token limits - Test assistant.usage events - Test no compaction events when infinite sessions disabled
The compaction trigger test requires real API calls to get realistic token counts. The replay proxy doesn't provide the token usage data needed for the CLI to trigger compaction.
The test requires a CLI build with infinite sessions support. Run locally with COPILOT_CLI_PATH pointing to a local CLI build.
Add e2e tests for context compaction to Go, Python, and .NET SDKs: - Test that compaction triggers with low thresholds and emits events - Test that no compaction events occur when infinite sessions disabled - Verify session still works after compaction (context preserved via summary) These tests mirror the existing Node.js compaction tests.

Added e2e tests. They won't pass until we ship the release that supports infinite sessions. |
