N?? and `show PKG` now print the installed record in the package
manager's own key/value layout, after one line explaining the format:
# lines starting with > come from the upstream candidate: a differing
value, or a field the installed record lacks
After each field whose candidate value differs comes the candidate's
line prefixed with "> "; fields only the candidate has are appended the
same way; installed-only fields stay; identical fields print once.
Multi-line values (pacman Optional Deps, dnf Description, RFC-822
continuation lines) are compared as blocks and a differing candidate
block gets "> " on every line. A package that is not installed shows the
candidate alone ("# not installed: this is the upstream candidate").
Merged where the backend gives comparable records for both sides:
- pacman: -Qi vs -Si REPO/PKG, REPO = the first repository -Sl lists
- apt: dpkg-query -s (Status, Conffiles, the long description; richer
than apt-cache show PKG=<installed>, which gives the archive record
when that version is still listed) vs apt-cache show --no-all-versions;
Description-xx pairs with Description and a one-line candidate
Description equal to the installed first line counts as identical
(the archives ship the long text in Translation files)
- dnf: info --installed vs info --upgrades (--available lists other
architectures first and nothing for an up-to-date package); not
installed: --available; dnf5's differently padded keys are re-padded
zypper keeps `zypper info --requires`: rpm -qi and zypper info share
almost no keys and zypper cannot print the installed record itself.
No candidate, or not exactly one record per side, keeps the old output.
Formats verified in containers and recorded in discovery/*.md. Unit
tests replay recorded pacman, apt, dnf4 and dnf5 records; the E2E suite
checks 2?? on su-dummy-b on all 12 distros.

Description : The glibc package contains standard libraries which are used by
|
|
: multiple programs on the system. In order to save disk space and
|
|
: memory, as well as to make upgrading easier, common system code is
|
|
: kept in one place and shared between programs. This particular package
|
|
: contains the most important sets of shared libraries: the standard C
|
|
: library and the standard math library. Without these two libraries, a
|
|
: Linux system will not function.
