feat: enable checksum validation by default in install-gh-aw.sh#29223

- Change SKIP_CHECKSUM default from true to false in both install-gh-aw.sh and actions/setup-cli/install.sh - Remove redundant SKIP_CHECKSUM=false in GitHub Actions context block (no longer needed since it's now the default) - Update header comments to reflect checksums are validated by default Agent-Logs-Url: https://github.com/github/gh-aw/sessions/73f24b82-4807-40b8-a61b-c662ee683ab0 Co-authored-by: pelikhan <4175913+pelikhan@users.noreply.github.com>

Replace `grep "$EXPECTED_FILENAME" | awk '{print $1}'` with
`awk -v f="$EXPECTED_FILENAME" '$2 == f {print $1}'` to avoid
false matches when the filename appears as a substring in another
entry (e.g. matching 'gh-aw-linux-amd64-extra.tar.gz' when
searching for 'linux-amd64').

Pull request overview
Enables SHA256 checksum validation by default in the gh-aw installer scripts now that checksums.txt is consistently published with releases.
Changes:
- Flip default
SKIP_CHECKSUMfromtrue→falsein both install scripts. - Remove the GitHub Actions-only
SKIP_CHECKSUM=falseoverride (now redundant). - Tighten checksum lookup to an exact filename match using
awk(instead of substringgrep).

The binary download and checksums download curl calls had no timeout options, causing them to hang indefinitely if a connection stalled. This was most visible on Windows GitHub Actions runners where the CI job ran for 3 hours before being killed. Add --connect-timeout 15 --max-time 120 to the binary download and --connect-timeout 15 --max-time 60 to the checksums download so the retry loop can cycle and eventually fail with a clear error instead of hanging forever.

…30s timeout The Windows CI job was hanging in the install script at the binary verification step (lines 376/399): `"$BINARY_PATH" --help` and `"$BINARY_PATH" version` can stall indefinitely while Windows Defender scans the newly downloaded executable. - .github/workflows/install.yml: add `timeout-minutes: 5` to the test-install job so a hung Windows runner is killed in under 5 minutes instead of consuming the full runner quota (previously 3+ hours) - install-gh-aw.sh / actions/setup-cli/install.sh: set BINARY_EXEC_TIMEOUT to `timeout 30` on Windows, wrap both binary verification calls with it; on timeout emit a warning and continue rather than failing the install (the binary has already passed checksum verification so it is safe to use) Agent-Logs-Url: https://github.com/github/gh-aw/sessions/9be8cef1-6312-4362-a598-ab4c831a4838 Co-authored-by: pelikhan <4175913+pelikhan@users.noreply.github.com>

…ication step The workflow's "Test full install script" step was also calling the installed binary directly without timeout protection: - `"$BINARY_PATH" version` - `"$BINARY_PATH" --help` On Windows, Windows Defender scans the newly downloaded binary before allowing execution, which can block these calls for several minutes — the same root cause that already affected the install script itself. The previous fix (623d0ea) protected the binary calls *inside* install-gh-aw.sh, but the workflow step's own verification calls remained unprotected and accounted for the remaining ~3:47 hang observed in run 25195877402. Fix: add `BINARY_EXEC_TIMEOUT="timeout 60"` on Windows in the workflow step, matching the pattern already used in the install script. A timeout exit (code 124) emits a warning and passes (the binary already passed checksum verification); any other non-zero exit still fails the step.

Two bugs in upgradeExtensionIfOutdated when --pre-releases is used: **macOS bug** (observed in run 25228001863/job 73985895593): gh extension upgrade --force resolves the upgrade target internally via /releases/latest which excludes prereleases. On macOS the binary is not locked so the first attempt "succeeds" but installs an older stable release instead of the desired prerelease (e.g., v0.71.1 instead of v0.71.3). After the call returned success the code blindly printed "upgraded to v0.71.3" while the installed binary was actually v0.71.1. Fix: when includePrereleases=true on a non-rename-workaround platform (macOS), skip gh extension upgrade --force entirely and use the pin-based path (gh extension remove + gh extension install --pin latestVersion) which installs exactly the version we determined. **Windows bug** (observed in the same run/job 73985895646): The rename workaround renames gh-aw.exe to gh-aw.exe.PID.bak inside the extension directory. On Windows the OS prevents deleting a file that is open by a running process, so gh extension remove cannot delete the extension directory (which still contains the .bak file). This leaves the directory in place, causing gh extension install --pin to fail with "there is already an installed extension that provides the 'aw' command". Fix: after renaming the binary on Windows, immediately move the .bak file to the OS temp directory so that the extension directory is empty and gh extension remove can succeed.

Per code review:
- Replace 'non-rename-workaround platform' with the specific platform
name ('macOS') and explain WHY we skip gh extension upgrade (it uses
/releases/latest which ignores prereleases)
- Add clarifying comment that the guard is only needed for macOS since
Linux/Windows are protected by the binary-lock-induced failure path
- Replace Unicode arrow '→' with ASCII '->' in the Windows backup log
message for consistent rendering across terminal environments

Summary
Enable SHA256 checksum validation by default when installing the gh-aw binary, and fix several latent issues that became reachable once checksum validation runs on every install.
Background
scripts/build-release.shalready generates achecksums.txtfile during the build process, and the release workflow uploads alldist/*files (includingchecksums.txt) to every GitHub release. The validation logic in both install scripts was fully implemented but gated behindSKIP_CHECKSUM=true(the default), pending checksums being available in releases.Since checksums are now consistently published, this PR flips the default to
SKIP_CHECKSUM=false.Changes
Install scripts (
install-gh-aw.sh/actions/setup-cli/install.sh)SKIP_CHECKSUM=true→SKIP_CHECKSUM=false; remove redundantSKIP_CHECKSUM=falseoverride in the GitHub Actions context block; update header commentgrep "$EXPECTED_FILENAME" | awk '{print $1}'(substring match) withawk -v f="$EXPECTED_FILENAME" '$2 == f {print $1}'(exact field match) to prevent false positives--connect-timeout 15 --max-time 120/60tocurlcalls to prevent indefinite hangs when connections stall on Windows runnersBINARY_EXEC_TIMEOUT="timeout 30"on Windows wrapping the post-install binary verification calls (--help,version), matching the existing pattern forgh extension install; on timeout a warning is emitted and the install completes (the binary already passed checksum verification).github/workflows/install.ymltimeout-minutes: 5to thetest-installjob so hung Windows runners are cancelled quicklyversion,--help) withtimeout 60on Windows, preventing the step itself from hanging after the install script completespkg/cli/update_extension_check.gogh extension upgrade --forceresolves the upgrade target via/releases/latestwhich excludes prereleases; on macOS the binary is not locked so the first attempt "succeeds" but installs an older stable release instead of the desired prerelease.
