Review: abduco 0.6-1
Package Information
| Description | lightweight session attach/detach manager abduco provides session management i.e. it allows programs to be run independently from their controlling terminal. That is, programs can be detached - run in the background - and then later reattached. Together with dvtm it provides a simpler and cleaner alternative to tmux or screen. abduco can also be used as a stand-alone replacement for dtach. |

Changelog
abduco (0.6-1) unstable; urgency=medium
.
* Initial release (Closes: #900387).
Reintroduces abduco, removed in 2016 over Bug #771102 (alleged dtach
code reuse); see d/copyright for how the flagged loci have been
rewritten or removed in abduco 0.6 and what remains shared.
* d/rules: enable hardening=+all (adds bindnow), pulling the flags in via
/usr/share/dpkg/buildflags.mk so the maint option is actually honoured;
a direct $(shell dpkg-buildflags ...) did not see it and dropped bindnow.
* d/control: drop comma-without-space synopsis (lintian
odd-mark-in-description).
* d/copyright: document the 2016 removal over Bug #771102 (alleged dtach
code reuse), and how the loci flagged then have been substantively
rewritten or removed in abduco 0.6 (packet struct field widths and
buffer size, VSUSP / SIGTSTP suspend dance, "\033[999H" EOS constant,
sigaction vs signal, multi-client server). Notes what remains shared
(wire-protocol enum values, overall packet shape) and points at
upstream's README acknowledgement of dtach as prior art.
* d/copyright: use the full real name on the debian/* copyright line to
match the Maintainer field.
* d/control: point Vcs-* at salsa.debian.org/debian/abduco
(the Debian-namespace packaging repo).
* d/control: use a dedicated maintainer address (debian@jayenashar.org)
to limit address harvesting from the published archive indices.
* d/patches: add verbose-build.patch so the upstream Makefile prints the
real compile/link commands; blhc reported NONVERBOSE BUILD and failed
the Salsa CI hardening job..dsc

Comment:
abduco was previously in Debian (0.1-1, 0.1-2; 2014-2016) and was
removed in May 2016 after Debian bug #771102, where Ned T. Crigler
(dtach upstream) reported that abduco's packet protocol and keyboard
suspend-handling code at the time appeared to be derived from dtach
0.8 (GPL-2+) rather than original ISC-licensed work.
.
Comparing abduco 0.6 (this upload) against dtach 0.8 the loci
Crigler highlighted have been substantively modified or removed
since the 2014 report:
* the packet struct now uses unsigned int / size_t fields and a
BUFSIZ-sized buffer (rather than dtach's unsigned char + sizeof
(struct winsize));
* the VSUSP / SIGTSTP suspend dance and the "\033[999H" EOS escape
constant have been removed from the keyboard input handler;
* signal installation uses sigaction(2) rather than signal(2);
* the architecture is now multi-client (Server with a linked list
of Clients, vs dtach's single-attached-client model).
.
What remains shared with dtach is the wire-protocol message-type
enum values (0..4: push/content, attach, detach, winch/resize,
redraw) and the overall packet shape ({ type; len; union { buf;
winsize; ... } }). These are functional protocol elements rather
than expressive code.
.
abduco upstream's README explicitly cites dtach as prior art ("abduco
is in many ways very similar to dtach", plus an "Improvements over
dtach" section), and a historical upstream commit (4fdb48d) is titled
"Change default key bindings to match dtach".
