# The source tarball comes FIRST: the Debian lane takes the first remote Source

# needs Go >= 1.26, which most of our targets lack -- but it is READ at %%build:
# for LICENSE/README/DRIVES.csv, for the manpage, and to check that the binaries
# below were built from exactly this commit (dreamdump-build.sh verify).

%description
dreamdump reads the high-density area of a Sega Dreamcast GD-ROM through raw
SCSI READ CD commands, checks each section by reading it repeatedly, and
writes the result as track files. MPF uses it as one of its dumping programs.

It needs a drive that can be made to read the high-density area; upstream's
record of tested drives is in the manual page and in DRIVES.csv. Other drives
are used with default settings and are untested.

No root, no group and no file capability is needed: every SCSI command
dreamdump sends (INQUIRY, SET CD SPEED, READ CD) is permitted to any user who
can open the drive, which systemd-logind grants to the user at the local seat.

This package follows the dreamdump release MPF bundles.

%changelog
* Mon Oct 12 2026 gmipf <gmipf64@gmail.com> - 0.6.0-2
- %%check runs the packaged binary (dreamdump-build.sh selftest): on the
  aarch64 chroots the first execution of the arm64 binary before a user's.

* Mon Oct 12 2026 gmipf <gmipf64@gmail.com> - 0.6.0-1
- Initial package. Repackages upstream's static release binaries for x86_64
  and aarch64, at the dreamdump release MPF bundles (0.6.0).
- The build checks that both binaries carry the commit of the shipped source
  tarball (vcs.revision vs. the archive's pax header), and fails if the source
  sends a SCSI opcode outside INQUIRY / SET CD SPEED / READ CD: the package
  ships without cap_sys_rawio, measured as a plain user on 2026-10-12.
- dreamdump(1) is generated from the same source: commands and options from
  the code, the tested-drive table from DRIVES.csv. Upstream ships no manpage.
