`::set-env::` and `::add-path::` let a step rewrite the environment of every later step from its own output, which the runner honoured silently. They are now refused, as GitHub has done since 2020, and `ACTIONS_ALLOW_UNSECURE_COMMANDS` opts back in per step or job. Support for that variable is new here too, and is the only opt-in, matching GitHub rather than adding a runner config key on top. Annotations keep their source location: Gitea has no annotation store and its web UI strips command properties, so `::error file=main.go,line=12::msg` is rendered as `::error::main.go:12: msg`. `DEVELOPMENT.md` writes down the log line encoding rules this relies on. --------- Co-authored-by: silverwind <me@silverwind.io> Reviewed-on: https://gitea.com/gitea/runner/pulls/1109 Reviewed-by: silverwind <2021+silverwind@noreply.gitea.com> Co-authored-by: bircni <bircni@icloud.com>

Job log line format
Gitea stores one log row per line and its web UI decodes the payload, so getting the encoding wrong never fails a test here, it only shows up in the browser.
A row cannot contain a real newline. FormatLog rewrites \n to a literal backslash-n and
truncates at 64 KiB on a byte boundary.
The payload of a line starting with a recognised prefix is decoded, with the escape set depending on the prefix:
| prefix | decodes |
|---|---|
##[error] ##[warning] ##[notice] ##[debug] ##[group] ##[endgroup] ##[add-matcher] |
%25 %0D %0A %3B %5D |
::error:: ::warning:: ::notice:: ::debug:: (with or without key=value properties), ::group:: ::endgroup:: ::add-matcher:: |
%25 %0D %0A |
##[command] [command], or no recognised prefix |
nothing |
Rules
- Emitting a command line? Escape the payload with
runner.EscapeCommandData. One escaper covers both forms: it escapes%first, so a literal%3Bbecomes%253Bthat the extra##[…]rules cannot match, and a raw;or]is never decoded. It is also what makes multi-line work,\nbecomes%0Aand the UI turns it back into a line break. - Forwarding a command from step output? Leave the payload alone, it arrived escaped and is decoded once. Decoding here double-decodes and destroys multi-line.
- No prefix? Do not escape, and split multi-line values into one row each.
- Interpolating a secret? Masking runs after escaping, so
AppendSecretMaskerregisters the encoded forms too. - Command properties also escape
%3Aand%2C, which the UI never decodes, so the reporter decodes exactly those two when folding a location into an annotation.
