From c5c2ee9516fb36db2dd2bfa52f3977a9f003c785 Mon Sep 17 00:00:00 2001 From: Tanishq Dubey Date: Tue, 14 Oct 2025 22:35:43 -0400 Subject: [PATCH 1/2] Implement Milestone 4: Synchronization and Remote Interaction MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This milestone adds comprehensive remote synchronization and stacked-diff publishing capabilities to Onyx. ## New Features ### Rebase Engine (internal/git/rebase.go) - Stacked rebase with sequential commit rebasing - Conflict detection and handling - Integration with rerere for automatic conflict resolution - Support for rebase continuation and abort operations ### Rerere Integration (internal/git/rerere.go) - Conflict resolution recording and replay - Cache location: .onx/rerere_cache - Automatic application of previous conflict resolutions - Normalized conflict pattern matching via SHA1 hashing ### Conflict Resolution UI (internal/git/conflicts.go) - Index-based conflict detection (stage 1/2/3) - Clear conflict presentation with file paths and hashes - User-friendly resolution guidance - Conflict marker extraction and analysis ### Remote Commands #### onx sync (internal/commands/sync.go) - Fetch latest changes from remote - Rebase workstream stack onto updated base branch - Automatic rerere conflict resolution - Transaction-based with full undo support - Progress reporting and clear error messages #### onx push (internal/commands/push.go) - Push all workstream branches to remote - Support for force push operations - Per-branch progress reporting - Clear summary of pushed branches ### Remote Helpers (internal/git/remote.go) - Remote validation and configuration - Support for multiple remotes with origin default - URL retrieval and remote existence checking ## Implementation Details - All operations wrapped in oplog transactions for undo support - Comprehensive error handling and user feedback - Integration with existing workstream management - CLI commands registered in cmd/onx/main.go ## Status Milestone 4 is now complete. All core synchronization and remote interaction features are implemented and tested. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude --- .gitignore | 1 + cmd/onx/main.go | 2 + internal/commands/push.go | 168 ++++++++++++++++++++++ internal/commands/sync.go | 207 +++++++++++++++++++++++++++ internal/git/conflicts.go | 187 +++++++++++++++++++++++++ internal/git/rebase.go | 207 +++++++++++++++++++++++++++ internal/git/remote.go | 106 ++++++++++++++ internal/git/rerere.go | 286 ++++++++++++++++++++++++++++++++++++++ notes/checklist.md | 83 +++++------ notes/future.md | 55 -------- 10 files changed, 1201 insertions(+), 101 deletions(-) create mode 100644 internal/commands/push.go create mode 100644 internal/commands/sync.go create mode 100644 internal/git/conflicts.go create mode 100644 internal/git/rebase.go create mode 100644 internal/git/remote.go create mode 100644 internal/git/rerere.go diff --git a/.gitignore b/.gitignore index e26a85f..c2cfc2f 100644 --- a/.gitignore +++ b/.gitignore @@ -32,3 +32,4 @@ go.work.sum # .vscode/ bin/ +.onx/ diff --git a/cmd/onx/main.go b/cmd/onx/main.go index 43f6820..e0eb196 100644 --- a/cmd/onx/main.go +++ b/cmd/onx/main.go @@ -29,6 +29,8 @@ log for universal undo functionality.`, rootCmd.AddCommand(commands.NewNewCmd()) rootCmd.AddCommand(commands.NewListCmd()) rootCmd.AddCommand(commands.NewSwitchCmd()) + rootCmd.AddCommand(commands.NewSyncCmd()) + rootCmd.AddCommand(commands.NewPushCmd()) // Execute the root command if err := rootCmd.Execute(); err != nil { diff --git a/internal/commands/push.go b/internal/commands/push.go new file mode 100644 index 0000000..4385e72 --- /dev/null +++ b/internal/commands/push.go @@ -0,0 +1,168 @@ +package commands + +import ( + "fmt" + "os" + + "git.dws.rip/DWS/onyx/internal/core" + "git.dws.rip/DWS/onyx/internal/git" + gogit "github.com/go-git/go-git/v5" + "github.com/go-git/go-git/v5/config" + "github.com/spf13/cobra" +) + +// NewPushCmd creates the push command +func NewPushCmd() *cobra.Command { + var remoteName string + var force bool + + cmd := &cobra.Command{ + Use: "push", + Short: "Push the current workstream to the remote repository", + Long: `Push all branches in the current workstream to the remote repository. + +This command will push each commit's branch reference to the remote, +allowing you to share your stacked diff workflow with others or create +pull requests for each commit in the stack.`, + RunE: func(cmd *cobra.Command, args []string) error { + return runPush(remoteName, force) + }, + } + + cmd.Flags().StringVarP(&remoteName, "remote", "r", "origin", "Remote to push to") + cmd.Flags().BoolVarP(&force, "force", "f", false, "Force push (use with caution)") + + return cmd +} + +// runPush executes the push command +func runPush(remoteName string, force bool) error { + // Get current directory + cwd, err := os.Getwd() + if err != nil { + return fmt.Errorf("failed to get current directory: %w", err) + } + + // Check if this is an Onyx repository + if !core.IsOnyxRepo(cwd) { + return fmt.Errorf("not an Onyx repository.
