Fixed missing session directory errorPublic

Searching for targeted insights

I'm thinking I might need to conduct a more focused search, possibly by reviewing a relevant file in full. This could help me inspect the packages or coding agent files that are relevant to my current task. I'll look into session working directory (cwd) and use session metadata, employing tools like rg for cwd and creating an Agent Session Runtime. It’s all about getting that information sorted clearly!

Inspecting source files

I’m thinking I need to examine the actual source code instead of just relying on the README. It might be enough to deduce that the session file stores the current working directory (cwd) and runtime context for changing directories. I'll probably have to search more effectively, perhaps looking in the dist or src folders. It seems like the "createAgentSessionRuntime" might be located in the current source, so I plan to use "rg" with the exact name.

Investigating session header paths

I need to find the session header path. The stack trace destination points to '/Users/user/workspaces/pi-mono', while the original current directory is '/Users/badlogic/workspaces/pi-session-redactor'. Now, if I'm trying to change the directory to the destination, I see a Node error. It seems the current working directory from the session header might not exist, especially since the user is trying to use sessions from a different project. I should look into the session format in the documentation.

Explaining possible causes

I'm trying to explain the likely cause of an issue and explore options. If someone is using redacted sessions from another machine, it can mess with the current directory. If that path is invalid, it could cause a crash.

I might mention the use of --fork and how it relates to copying the session header. The --session parameter could be an issue if it resolves an incorrect path, leading to Node throwing an error before any proper handling occurs. Suggesting the --fork option could be helpful!

Analyzing session path issues

I need to clarify that without prompting to fork, an explicit path can bypass the global prompt, leading directly to the session. When the runtime changes to the session's current directory, it might crash if the file's cwd comes from a different machine.

I should mention how SessionManager.open() reads the header and uses that cwd, which might not exist on the current machine. A couple of potential fixes could include editing the cwd in the JSONL file for temporary inspection or considering the session import/fork mechanism.

Exploring the --fork option

I’m considering the --fork <path> option. If the header cwd is invalid, then forkFrom can load entries without requiring a cwd. It reads the source entries but doesn't change the cwd since it writes a new header with the target cwd instead.

In the createSessionManager, for the --fork path, or local/global settings, it returns forkSessionOrExit(sourcePath, cwd), which uses the current cwd as the target. This helps avoid crashes related to invalid paths!

Clarifying CLI Flags Usage

I need to focus on discussing usage rather than implementation unless asked directly. It's important to explain the misuse of command-line interface flags. I should inspect whether parseArgs supports the --fork flag, which expects an argument rather than a boolean, and cannot be combined with --session. I should also mention the correct syntax, like pi --fork ./path, and explain what happens if the session path is not found. Let’s keep it concise and technical.

Planning technical response

I see that I need to summarize the user’s suggestion without jumping into implementation unless they ask for it. I'll aim for a concise summary of the technical design and hopefully align with their expectations. It might be useful to mention the difference between interactive and non-interactive behavior while keeping it manageable. I also want to propose an expected flow along with some edge cases to consider. Let’s focus on crafting a clear, direct response!

Planning file modifications

I need to fully read the relevant files before making any edits. It seems like my first message should clearly define the task. I need to modify the code, and likely the files I'll deal with are main.ts and core/agent-session-runtime.ts. I should inspect the arguments and modes, and maybe create a simple warning TUI using something like promptConfirm. The user requested a minimal TUI for warnings, so I need to explore what confirmation components we already have. Let's inspect the architecture.

Exploring TUI implementation

I’m considering whether I can instantiate a simple TUI (Text User Interface) using ProcessTerminal to display text. I think I need to understand the keyboard handling API better, maybe even search for examples or small components that can help. It seems like there’s a lot to explore in making this work, but I'm focused on finding the right details to get started. Let's see what I can find!

Considering a simple TUI implementation

I'm thinking about creating a tiny new file that might be simpler. Using getKeybindings could work, but the user explicitly wants a simple TUI. So, it might be better to implement it with pi-tui in a minimal way. I can create a helper in main.ts using TUI components, though I need to add some imports. I’m also weighing whether to use raw input without keybindings since keeping things simple should be the priority. But I do want to ensure a good UI layout for the user!

Exploring TUI component options

I'm considering using components like TUI, ProcessTerminal, Container, Text, and Spacer, and maybe also getKeybindings. I need to check how focusable inputs work, and I might implement a new component that extends Container with a handleInput method, which should cover the need. I'm curious about whether handleInput is called when focused, and searching for the Focusable interface might help. I think some components, though not implementing Focusable, still have handleInput. I could create a new file for MissingCwdPrompt, but the user didn’t ask for diffs. Maybe a minimal component in main.ts would suffice?

Considering imports and modifications

I'm thinking about importing directly in main.ts to bring in the interactive component from the CLI main. That could work fine, but I need to consider whether I need to read a file for the new component. It seems like I only need to modify main.ts, although if I add a helper, I might have to adjust session-manager too. Also, I should detect any missing current working directory, and I might need to create a controlled error type for that!

Considering error handling

I think it might be easier to implement error handling in JSON format. If the app mode is set to "json", I could log the error using console.log, specifically formatting it to show the error code and relevant messages. I need to check the documentation to see if there's a specific format for JSON or if the event stream has similar "type: error" messages. It seems like a good idea to verify this before proceeding.

Considering TUI integration

I'm thinking about how to add the export for the helper feature. It might make sense to implement a prompt that aligns with the current theme from the startupSettingsManager. While I could use promptConfirm with readline for non-TTY environments, the user specifically requested a simple TUI. So, I should prioritize that. I need to figure out how to integrate the TUI prompt before runtime and look into using TUI from pi-tui, specifically checking for stop() usage to manage the terminal properly.

Investigating API needs

I might need the API for TUI.stop, so I’m considering whether to search in node_modules. But I think I can infer what I need. I’ll inspect its use in interactive mode, focusing on stop(): void, particularly around line 1800. This should give me a clearer idea of how to proceed. Let's dive into that and see if I can figure things out from there!

Considering keybindings and functions

I'm thinking about whether to use a special startup prompt outside the main app. It might be fine, but I believe needing configuration is important. I should double-check the keybindings manager if I'm not modifying anything. It could help to read the partial docs or search for export names using bash's rg. I'll explore that further to ensure I'm on the right track!

Designing a helper file

I’m looking at a helper file that involves checking for session files and current directories. If a session file doesn’t exist, I won’t need to check the current working directory, but if it does, I should validate it. If the current path exists, there’s no problem. I also want to consider if I'm dealing with in-memory sessions or new files, and maybe include the term storedSessionCwd for clarity. It feels like I’m covering all bases!

Setting up main.ts

In main.ts, I’m considering whether or not to import something if the helper function already takes care of it. Once I create the session manager, I’ll check for any missing session current working directories using getMissingSessionCwdIssue. If there’s an issue and the app is in interactive mode, I should prompt the user for confirmation about whether to continue. If they choose not to, I’ll stop the theme watcher and restore standard output. Maybe I should also think about handling exit codes more gracefully.

Considering custom error handling

I need to catch a custom error in RPC mode and return a success false response from the switch_session command. This seems under control and would address runtime issues during the switch_session process after startup. If --session is missing the cwd in RPC mode, the main part should handle it, while the runtime could throw a MissingSessionCwdError later. I'll need to inspect the outer catch handling in handleCommand and search lower for adjustments.

Considering command handling

I’m thinking about needing an outer command parser to manage errors more effectively. It might be worth exploring how to handle errors generically, perhaps looking into a "handleCommand" method that could include a catch mechanism. I want to ensure everything is running smoothly, so I’ll have to revisit that later to address potential issues. This way, I can be more prepared for any command-processing challenges that arise!

Considering implementation details

I’m thinking we should implement this in the core runtime to avoid using raw Node stack anywhere. It seems replacing it with a plain Error could be a good idea. This might streamline things and improve overall performance or clarity. I wonder how this will affect existing functionality or if there are potential edge cases we need to consider. Let's make sure we’re thorough in how we approach this to avoid any issues down the line.

Clarifying stored cwd usage

I could mention that the stored cwd (current working directory) is utilized for project settings, AGENTS.md discovery, and setting relative tool paths. That sounds nice and makes it clear why it's important to have the cwd correctly set. It helps in organizing everything better and ensuring that tools can find what they need to operate smoothly. Overall, I think it's a helpful addition.

Planning reading strategy

I need to read the remainder of the document, specifically from 1444 to 3789 and 4120 to the end. I've already tackled sections 1-1443 and 3790-4450, but maybe not all of those. To ensure I get the full picture, it might make sense to read those chunks sequentially: first 1444-3789 and then 4451 to the end. Okay, let's go with that plan!

Considering session switches

I'm thinking about the call sequence for session switching. It seems that emitBeforeSwitch gets triggered even before teardown, which isn't ideal. Then, it runs again on the second call. I wonder if extensions might see those duplicate session_before_switch events. Maybe it would be better if runtimeHost.switchSession could detect the issue itself before emitBeforeSwitch is called? After all, it currently emits this signal before opening a new session.

Evaluating test strategies

I’m considering whether to add tests to the runtime-events file or create a new file, which seems easier. I might skip TUI prompt tests. One idea is to implement a unit test for switchSession with a missing cwd that triggers a MissingSessionCwdError, while a cwdOverride should work. I think I should set up a new test file to exercise runtime logic using a helper. I may also test the getMissingSessionCwdIssue if it’s simple, but a runtime test sounds adequate.

Planning session tests

I need to determine if runtimeHost's current session points to the tempDir. I’m thinking about creating a missing session file in the same or a separate session directory. We’d write a JSONL file with only the header, and SessionManager.open would handle loading entries and sessionId. Once the session context is built with runtimeHost.switchSession, it should function well, but I need an existing current session for switching.

I’m outlining a pseudo test to check for a controlled error when the session cwd is missing, including an override option. I need to be sure that the session file uses an absolute path after switching.

Crafting edits carefully

I'm planning to make edits thoughtfully. I could either write new files or edit existing ones. Specifically, I need to focus on creating new files like core/session-cwd.ts and cli/missing-session-cwd-prompt.ts. This approach will help ensure that everything is organized and functional. I want to make sure I handle the implementation efficiently. Let’s take it step by step!
