2026-07-01ci: pin the exact JDK releaseLena2-3/+6
The Adoptium "latest 17 GA" endpoint floats while versions promises never to float. Pin the full Temurin build and fetch it by version.
2026-07-01app: anchor the picker start path at the storage rootLena1-2/+6
The containment check was a bare prefix match, so a sibling such as /storage/emulated/0-evil passed for a root of /storage/emulated/0.
2026-07-01app: write config atomicallyLena1-1/+7
A crash mid-write corrupted config.json, and every later load then threw on parse, crash-looping the app until its data was cleared, losing the key and pinned host. Write to a temp file and rename.
2026-07-01app: kill rsync when a sync is stoppedLena2-4/+19
A stopped worker (schedule replaced, constraints lost) left rsync running detached until its own network timeout, including a window where a WiFi-only sync kept pushing on another network. A watchdog coroutine destroys the process on cancellation, which also closes its pipes and unblocks the log reader; the worker rethrows cancellation instead of logging it as a folder error.
2026-07-01app: refuse folder mappings with empty pathsLena2-4/+16
The trailing-slash fix-up turns an empty local path into /, so a blank folder row would rsync the entire filesystem; an empty remote path pushes into the rrsync root. Reject both when saving a folder, skip and log them at run time in case the config was edited by hand, and log why a sync was skipped when the app is not configured yet.
2026-07-01rsh: reject an invalid RSH_PORTLena1-8/+19
A garbage or out-of-range port silently fell back to 22 and connected to the wrong place; fail loud instead.
2026-07-01keys: never write the plaintext private key to diskLena4-42/+41
rsh -keygen printed the pubkey but wrote the key pair into a directory, so generating a key briefly left the plaintext private key on flash, contradicting the documented invariant that it only ever exists in memory. -keygen now emits the private key PEM on stdout and nothing else; the app encrypts it immediately and derives the public key via -pubkey, reusing the validated import path. Keygen failures now surface as an error dialog instead of crashing the app from a bare thread.
2026-06-01app: add a folder picker for local paths0.1.0Lena6-5/+223
Typing absolute paths is error-prone; let the user browse real filesystem folders and pick one. Stays on real paths (no SAF) so rsync keeps operating on POSIX paths.
2026-01-01rsend: push phone folders to a home SSH host over rsyncLena85-0/+4772
A small Android app for one-way folder backup, a KISS alternative to Syncthing. It bundles rsync (built from pinned source via the NDK) and a pure-Go SSH transport, both shipped in the APK as lib*.so and run from the native library directory. rsend pins the host key, stores the ed25519 identity Keystore-encrypted, pushes each folder additively or as a mirror, and runs on demand or on a WiFi-only schedule. The build is self-contained and reproducible: make setup provisions the toolchain, make builds rsync, rsh, and the APK.
