ACE now supports only Linux and macOS.

Changes

  • .goreleaser.yaml: no Windows binaries and no .zip archives.
  • pkg/common/secure_file_windows.go (new): stops the build on Windows with the error undefined: ACE_does_not_support_Windows. Without it, go install and go build would still make a Windows binary that writes unprotected reports.
  • pkg/common/secure_file.go: a comment says that the helpers depend on POSIX modes and points to secure_file_windows.go.
  • docs/install.md: says that ACE supports Linux and macOS only. Windows users should run ACE in WSL or in the container image and keep the output directory on the Linux file system. Windows drives do not keep POSIX file modes.

⚠️ Breaking Change

  • **Windows is no longer supported. Releases no longer include Windows binaries or .zip archives, and ACE no longer builds on Windows. ACE protects its reports with POSIX file modes, and Windows does not use these modes for access control, so other local users could read report
    files that contain table rows. On a Windows host, run ACE in WSL or in the container image, and keep the output directory on the Linux file system, not on a Windows drive.

    Upgrading: reports written by earlier Windows builds may be readable by other local users. Delete them, or restrict access manually.

ACE now supports Linux and macOS only. This is a breaking change for
users who run ACE on Windows or download the Windows release archives.

The helpers in pkg/common/secure_file.go make output files owner-only
with POSIX mode bits. On Windows, os.Chmod does not change the ACLs,
so other local users could read reports that contain table rows.

- GoReleaser does not build Windows binaries and does not make
  .zip archives any more.
- pkg/common/secure_file_windows.go stops the build on Windows, so
  "go install" and "go build" cannot make an unsafe binary there.
- The install guide says that ACE supports Linux and macOS only, and
  tells Windows users to run ACE in WSL or in the container image,
  with the output directory on the Linux file system.

📝 Walkthrough

Walkthrough

ACE release builds now target Linux and macOS. Windows builds fail at compile time. Installation guidance directs Windows hosts to WSL or the container image and describes report file-permission considerations.

Changes

Platform Support Restriction

Layer / File(s) Summary
Enforce the Windows build restriction
pkg/common/secure_file.go, pkg/common/secure_file_windows.go
The secure-file comments describe reliance on POSIX mode bits. A Windows-only file references an undefined identifier, causing Windows builds to fail.
Align releases and installation guidance
.goreleaser.yaml, docs/install.md
GoReleaser targets Linux and macOS and uses tar.gz archives. Installation guidance directs Windows hosts to WSL or the container image, explains output file-system requirements, and warns that reports from earlier Windows builds may retain ACLs readable by other local users.

Priority: ➖ Normal

Severity of issue fixed: Medium

Merge Risk: ⚪ Minimal · up to 1856b

No specific issue is established that would block merging; the platform changes still need normal build and release checks.

A rabbit checks the build by moonlit light,
Linux and macOS hop into the night.
Windows takes the WSL trail,
Or rides in a container without fail.
Keep report files where POSIX modes hold,
And guard old ACLs from eyes untold.

In `@docs/install.md`:
- Around line 5-6: Update the Windows filesystem guidance in the installation
documentation to clarify that reports from earlier Windows builds retain their
existing ACLs after future output is moved to WSL. Tell users to delete those
reports or manually restrict their ACLs to prevent other local users from
reading table rows.

Reports written by earlier Windows builds keep their Windows ACLs after
a move to WSL. The install guide now tells users to delete them or to
restrict their ACLs by hand.
