Before this change, the GUI server sent all static files uncompressed,
meaning the browser had to download the full size of every JS, CSS,
and HTML asset.
After this change, the GUI server uses chi's Compress middleware at
level 5, which negotiates gzip or deflate encoding based on the
client's Accept-Encoding header.
This reduces transfer sizes significantly for the web UI assets, for
example assets/index-CvfdU_RR.js is 874 KB uncompressed, and
265 KB compressed.
This is consistent with how rclone serve http, webdav, and restic
already compress their responses.
Previously `make fetch-gui` extracted the GUI release into cmd/gui/dist/
and the unpacked tree was embedded uncompressed via `//go:embed dist`.
This commits and embeds the GUI bundle (dist.zip) and its release tag
(dist.tag) to the repo so:
- the rclone binary is smaller
- `go build` works on a fresh clone without first running fetch-gui
- a given commit pins an exact GUI version
The "Fetch GUI" step was removed from .github/workflows/build.yml.
The flag.Lookup("test.v") check existed to skip opening a browser
during tests, but the tests don't exercise RunE, so this was never
used. The --no-open-browser flag is sufficient on its own.
Bind the RC server to localhost:0 and read the bound URL back via a
new rcserver.Server.URLs() accessor instead of pre-allocating a port
in cmd/gui. This removes the small TOCTOU race window between
freePort() closing its listener and rcserver claiming the same port.
- Fail gracefully if `make fetch-gui` hasn't been run
- Return errors instead of panic or fatal errrors
- Don't run `make fetch-gui` on every make since we have it in the workflow
This adds a new gui command which runs an embedded copy of the GUI at
https://github.com/rclone/rclone-web/
The GUI release is fetched as part of the CI build.
