Add Ubuntu Linux port support#1
Conversation
SECURITY: - bindings.go: Change file permission from 0644 to 0600 (owner-only) STABILITY: - bindings.go: Add 500MB file size limit using os.Stat() BEFORE os.ReadFile() to prevent OOM - find.ts: Add 5-second timeout for regex operations to prevent runaway regex - bindings.go: Use cmd.Start() + goroutine with cmd.Wait() for RequestNewWindow to avoid blocking UI CORRECTNESS: - state.ts: Revert incorrect MOVE_COLS change - original i < startIndex - 1 was correct (the changed caused duplicate columns when moving columns left)
When double-clicking a cell to edit, instead of an inline textarea that shows scrollbars in small cells, a centered popup dialog now appears with: - Textarea for editing content (scrollable, resizable) - Save and Cancel buttons - Cell position indicator in header Benefits: - Text is always readable without scrollbars - Larger editing area for long content - Clear Save/Cancel actions Changes: - Add CellEditDialog component with overlay styling - Remove inline CellEditor from VirtualTable - Update App.tsx to render dialog when editing is active - Add CSS styles for dialog overlay and buttons
- Add ARIA attributes (role=dialog, aria-modal, aria-labelledby) - Add type=button to prevent form submission - Fix font-variantnumeric CSS typo -> font-variant-numeric - Stop keydown propagation to prevent global shortcuts - Reuse handleCommitEdit/handleCancelEdit instead of duplicating
fix: address code review findings - security, stability, and correctness

Thanks for the contribution and the thorough validation notes. After discussion we've decided not to take this PR and not to add Linux support to csv-editor at this time. Closing. Why1. We don't have an actual user request for Linux releases. This PR is the first Linux-related signal in the project's history, and it's a contribution offer rather than a user asking for binaries. csv-editor's primary value is correct CP932/Shift_JIS handling, and our user base is essentially macOS and Windows desktop users in Japan. We have no evidence of meaningful Linux desktop demand. 2. We can't responsibly maintain a platform we can't test. Maintainers work exclusively on macOS (Apple Silicon). We have no x86_64 Linux hardware, and running x86_64 Ubuntu under emulation on Apple Silicon is too slow to be practical for release verification. Shipping GUI binaries we cannot run ourselves to verify IME / theme / dialog / Wayland behavior would be a disservice to users. 3. The PR itself bundles three independent changes (Linux port, a modal cell-editor UI rewrite, and backend safety fixes in We'll update the README to make the platform scope explicit so future contributors can see this upfront. Thanks again for the time you put in. |
Make platform scope explicit in README (en/ja) and CLAUDE.md after closing PR #1. Maintainers have no Linux test environment and no Linux user demand has surfaced; future drive-by ports should be declined. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
CSV files may contain PII or other private data, but SaveFile created new files with 0644 — world-readable on disk under the default macOS umask (022). A save into a shared directory, a cloud-sync folder, or anywhere picked up by a third-party backup reader would expose rows to other local accounts. Drop the request mode to 0600 so the file is restricted to the owning user by default. Pre-existing files are unaffected (os.WriteFile only applies mode on create).

cmd.Start was followed by no cmd.Wait, so each File ▸ New Window invocation left a defunct entry in the parent's process table for the lifetime of the parent. On Windows where the spawned process is the csv-editor instance itself this is the actual leak; on macOS the spawn goes through open(1) which detaches almost immediately, so the goroutine returns quickly. Also adds the missing `return` after the cmd.Start error branch so we no longer fall through to wait on a process that never started. The goroutine intentionally discards Wait's error. A clean user-driven close exits 0, and a crash is already self-evident to the user (the child window disappears) — emitting a parent-side toast would be noise without new information. Refs: #1 Acknowledgments: Originally surfaced by @SweetSophia in the closed PR #1 "Add Ubuntu Linux port support". Ported as a standalone fix with a simplified error-handling strategy.

LoadFile previously called os.ReadFile unconditionally, so an open or drag-drop of a multi-gigabyte file would attempt to materialize the whole thing in RAM and OOM the app. csv-editor's stated target is "hundreds of thousands of rows" — roughly 100 MB worst case at typical column counts — so a 500 MB ceiling sits well above legitimate use while protecting against an accidental open on something pathological. The new readFileBounded helper reads through io.LimitReader capped at max+1 bytes, then rejects with "file too large" if the read consumed more than max. The +1 lets us tell "exactly at limit" (accept) from "exceeds limit" (reject) without ever allocating more than max+1, so a file that grows between Stat and Read (TOCTOU) still cannot exhaust memory. Directories are rejected explicitly with a clear message. Tests cover at-limit acceptance, oversize rejection, directory rejection, and missing-file error wrapping. Refs: #1 Acknowledgments: Originally surfaced by @SweetSophia in the closed PR #1 "Add Ubuntu Linux port support". Ported as a standalone change with freshly written helper, test cases, and threshold reasoning. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
Three runtime safety improvements + Linux scope clarification. - security: SaveFile mode 0644 → 0600 (PII protection on world-readable shared / cloud-synced paths under default macOS umask). - fix: RequestNewWindow now reaps spawned child via cmd.Wait goroutine, stopping the Windows zombie leak on every File ▸ New Window. - feat: LoadFile bounded to 500 MB via io.LimitReader. Open / drag-drop / Open Recent on multi-gigabyte files no longer OOM the app; users see a clear "file too large" error instead. - docs: README (en/ja) and CLAUDE.md declare Linux explicitly out of scope after closing PR #1. All three runtime changes were originally surfaced during review of the closed PR #1 by @SweetSophia; the code was rewritten from scratch with fresh helper signatures, tests, and rationale before landing.

This was supposed to be a personal port / PR. I was late and I had Kilo analyze and review everything I finished working on , and a general review sweep, so I could catch some sleep in the meantime. It looks like it fixed issues but also upstreamed the PR. Quite sorry. As for the Cell-Editor, this might be worth suggesting in an issue. I added it because when I click on a cell in Windows, I get scrolling bars bottom and right at the cell, shrinking the visible text area to like 40%, meaning I can't see anymore what I edit at all. So my idea was either removing the scrolling bars, popup when a cell is edited for text input, or something similar. I really like your editor, it's not bloated, fast, easy to work with, editing hundreds of rows is really fluid and readable! It just happens I work in System Integrations so I'm split between Windows and Linux systems at work and in thus also in my free time. That's why Linux port. |

No need to apologize — thanks for the honest context, and for the kind words about the editor. That clears up a lot. The bundled changes + the More importantly: your cell-editor bug report was spot on, and I owe you a thank-you for it. I dug into it and the root cause is exactly the scrollbar behavior you described:
So your On the Linux port: I hear you on the System Integration split — that's a completely legitimate need, and it's nothing against the work you put in. The decision is purely about what we can responsibly test and maintain on macOS-only hardware (details in the close comment above). For your own use, building from source on Linux with Thanks again for the report and the gracious note. Following up in #2. |

Following up: your cell-editor report shipped as a fix in v0.1.6. 🎉 https://github.com/nlink-jp/csv-editor/releases/tag/v0.1.6 What went out:
Verified on macOS and a Windows VM. Both came directly out of your report and the testing it prompted — thank you. Credited you in #2 and the changelog. Enjoy v0.1.6, and thanks again for the kind words and the precise bug report. |
