Both the in-app restart and the auto-update install previously
shelled out to cmd.exe so the new instance could wait for the old
one to release the singleton mutex and the locked exe file. On
some Windows configurations the `start ""` inside `cmd /c ...` can
flash a console window despite CREATE_NO_WINDOW + DETACHED_PROCESS
flags. The replacement spawns the child binary directly via
CreateProcessW; since the main exe is built with
windows_subsystem = "windows", no console is ever allocated.
- New `src/update/handoff.rs` exposes `spawn_detached`,
`wait_for_parent_exit`, and `cleanup_stale_old_exes`.
- New CLI flags `--wait-pid <pid>` and `--updated-to <version>`
parsed early in `main`; the child waits up to 5s on the parent
PID via OpenProcess+WaitForSingleObject before falling through
to a 3s mutex-acquisition retry.
- `restart_app` and `install::begin` both spawn detached children
using the new helper.
- Update install now uses MoveFileExW twice (rename running exe
sideways, then move staged exe into place with
MOVEFILE_REPLACE_EXISTING | MOVEFILE_COPY_ALLOWED so portable
installs on non-system drives still work). Rollback restores
the backup if either the swap OR the post-swap detached spawn
fails, and a MessageBoxW modal surfaces the backup path if the
rollback itself fails.
- First launch after an auto-update shows a blue-info tray
balloon "Updated to vX.Y.Z" via a new `tray::notify_info` (the
existing `tray::notify` is split into `notify_warning` +
`notify_info` sharing a `notify_inner`).
- Startup sweeps stale `<exe>.old.<pid>` siblings left by past
in-place updates.
- Three new `LocaleStrings` fields translated across all 8
supported locales (en/nl/es/fr/de/ja/ko/zh-TW).
GitHub's Releases API exposes a `digest: "sha256:..."` field on every
asset since 2024. We now parse it, hash the downloaded bytes locally,
and abort with ChecksumMismatch if they disagree. Releases that predate
the field (none currently exist for this repo) skip verification rather
than fail, so v0.1.0 / v0.1.1 / v0.1.2 still update normally.
cmd.exe expands `%var%` even inside double-quoted arguments, which
would let a path like `C:\Users\%PATHEXT%\bubble.exe` substitute the
expansion. Real Windows paths with `%` are vanishingly rare, so we
fail fast with UnsafePath rather than ship a bespoke cmd-escape
implementation.
Bumps version to 0.1.3.
Rust's std::process::Command escapes inner double quotes as \" when
wrapping the args(["/c", &cmd]) array. cmd.exe does not understand the
\" escape, so the swap-and-restart command got mangled: `start ""
"PATH"` arrived as `start \"\" \"PATH\"`, which the cmd parser
collapsed into `start \ PATH` — producing the "Windows cannot find
'\'" dialog and aborting the update.
Switching to raw_arg lets us hand cmd.exe the literal command line it
expects. The two quote characters cmd needs to keep are the outer pair
wrapping the whole /c argument; cmd's "more than two quotes, special
chars present" branch then preserves the inner path quotes intact.
Bumps version to 0.1.2 since this is the first updater fix that ships
through the updater itself for any future v0.1.2+ user.
