* docs(agents): add a comment-length rule Comments were growing to document rejected alternatives, past bugs and measurements. That belongs in the commit message, not the source. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * ci(drm): build the unattended-wayland deb in the release workflow The deb was built by a separate drm-capture workflow on a plain runner, so it diverged from every other Linux deb: different base, different vcpkg/ffmpeg, different toolchain. Move it into flutter-build.yml as build-rustdesk-linux-drm, mirroring build-rustdesk-linux's x86_64 path -- same ubuntu18.04 container, same vcpkg install, same rust and flutter. libdrmtap is built on the runner first and handed to the container via DRMTAP_PREBUILT_DIR, because bionic's meson is too old to build it. The job is ungated, so the --drm packaging path is exercised on every PR; only publishing stays gated on upload-artifact. drm-capture.yml is deleted along with docs/DRM_CAPTURE_SECURITY.md -- the 29 drm unit tests that workflow ran are no longer executed by CI. Three bugs the move exposed: - build.py anchored the libdrmtap paths on abspath(__file__), which is only cwd-independent on Python >= 3.9 (bpo-20443). The packaging container runs 3.6 and chdir's into flutter/, so the ABI-gate cross-check resolved one directory off and every --drm packaging run would have died with FileNotFoundError. Captured as REPO_ROOT at import instead. - DRMTAP_PREBUILT_DIR no longer needs DRMTAP_ALLOW_UNPINNED. A prebuilt dir inside the repo's own third_party/libdrmtap at the pinned sha is the pinned object, not an override, and is now verified as such. - The variant's Depends carried a bare libdrm2. libdrmtap needs drmModeGetFB2, so it is libdrm2 (>= 2.4.95); below that the package installed and could never capture. The loader also logs the dlerror now instead of discarding it, so a soname or glibc mismatch is named rather than surfacing as a generic "libdrmtap not available". Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * fix(drm): declare the unattended-wayland deb's real libc6 and libdrm floors libdrmtap is built on the ubuntu-22.04 runner while the rest of the deb comes from the ubuntu18.04 container, so the package has a mixed glibc floor and declared neither half. It installed happily on Ubuntu 20.04 / Debian 11 (glibc 2.31), then dlopen failed on GLIBC_2.34 and capture degraded to the PipeWire portal -- the one thing this variant exists to avoid. Measure the floor off the staged objects and put it in Depends, so apt refuses with a reason instead of handing over a package that can never capture. Measured rather than written down: the number moves whenever either base does, and it lands exactly on RHEL/Rocky 9 (glibc 2.34), where one off-by-one decides whether that whole family can install. drmModeGetFB2 landed in libdrm 2.4.101, not 2.4.95 -- checked against the libdrm tags, xf86drmMode.h first declares it in 2.4.101. The old floor admitted Debian 10 (2.4.97), where the .so is linked -z now and dies on an undefined symbol at dlopen. libdrmtap's own meson.build carries the same wrong number. Upload the deb on always(): the run that fails the drm check is the one whose artifact is most worth downloading. Publish stays gated on success, so an unverified build still cannot reach a release.

scrap
Scrap records your screen! At least it does if you're on Windows, macOS, or Linux.
Usage
[dependencies]
scrap = "0.5"
Its API is as simple as it gets!
struct Display; /// A screen.
struct Frame; /// An array of the pixels that were on-screen.
struct Capturer; /// A recording instance.
impl Capturer {
/// Begin recording.
pub fn new(display: Display) -> io::Result<Capturer>;
/// Try to get a frame.
/// Returns WouldBlock if it's not ready yet.
pub fn frame<'a>(&'a mut self) -> io::Result<Frame<'a>>;
pub fn width(&self) -> usize;
pub fn height(&self) -> usize;
}
impl Display {
/// The primary screen.
pub fn primary() -> io::Result<Display>;
/// All the screens.
pub fn all() -> io::Result<Vec<Display>>;
pub fn width(&self) -> usize;
pub fn height(&self) -> usize;
}
impl<'a> ops::Deref for Frame<'a> {
/// A frame is just an array of bytes.
type Target = [u8];
}
The Frame Format
- The frame format is guaranteed to be packed BGRA.
- The width and height are guaranteed to remain constant.
- The stride might be greater than the width, and it may also vary between frames.
