This is a list of features that are scheduled to be removed from dpkg.
|
|
|
|
What: fallback of dpkg-source to source format "1.0" without explicit debian/source/format
|
|
Status: deprecated
|
|
When: 1.17.x
|
|
Warning: program and lintian (missing-debian-source-format)
|
|
Why:
|
|
With the support of multiple source formats, the user should be explicit
|
|
about the desired source format. The fallback to "1.0" is there only for
|
|
backwards compatibility but will be removed once all packages have the
|
|
debian/source/format file. This is unlikely to happen before 1.17.x.
|
|
|
|
What --forget-old-unavail (dpkg option)
|
|
Status: obsolete
|
|
When: 1.16.x
|
|
Warning: program
|
|
Why:
|
|
Purged packages are properly cleaned up now by dpkg, and old unavailable
|
|
leftovers are automatically cleaned up on database parsing. So there's no
|
|
need anymore for this manual action.
|
|
|
|
What: --control-path (dpkg-query option)
|
|
Status: deprecated
|
|
When: 1.18.x
|
|
Warning: man page
|
|
This was a semi-public interface now superseded by --control-list and
|
|
--control-show, which are a better interface as they do not rely on any
|
|
specific database layout. Although there might still be cases where it's
|
|
required to avoid hardcoding the database layout, and it will be kept as
|
|
long as there's legitimate uses for it and no viable replacements.
|
|
|
|
What: -L (dpkg-parsechangelog option)
|
|
Status: obsolete
|
|
Since: 1.18.8
|
|
When: 1.19.x
|
|
Warning: program
|
|
Why:
|
|
The custom parsers have been switched from programs to perl modules,
|
|
and this option has no use any longer. The caller can set PERL5LIB or
|
|
PERLLIB to specify the perl module search path now.

History of feature removals
|
|
~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
What: cleanup-info (program)
|
|
Status: removed
|
|
Since: 1.15.0
|
|
Why:
|
|
This program was needed long time ago to fixup broken info dir files
|
|
generated by buggy install-info programs. Should not be needed anymore.
|
|
|
|
What: --largemem, --smallmem (dpkg option)
|
|
Status: removed
|
|
When: 1.15.1
|
|
Why:
|
|
These options have been no-ops for a long time.
|
|
|
|
What: --force-auto-select (dpkg option)
|
|
Status: removed
|
|
When: 1.15.1
|
|
Why:
|
|
This option has been a no-op for so long, that there's no traces on git
|
|
history of its usage.
|
|
|
|
What: recommended, contrib, base (priority)
|
|
Status: removed
|
|
When: 1.15.1
|
|
Why:
|
|
These priorities have been superseded by either other fields or values in
|
|
other fields.
|
|
|
|
What: 822-date (program)
|
|
Status: removed
|
|
When: 1.15.1
|
|
Why:
|
|
Should switch to use 'date -R'.
|
|
|
|
What: support of custom changelog parsers understanding only -v
|
|
Status: removed
|
|
Since: 1.15.5
|
|
Why:
|
|
The debian changelog parser has been enhanced. It supports new options
|
|
that enable more fine-grained retrieval of information. Those new options
|
|
will be used by scripts (like dpkg-genchanges).
|
|
.
|
|
Custom changelog parsers must be updated to support the new API (see
|
|
dpkg-parsechangelog(1) and README.api).
|
|
|
|
What: support for environment variable DPKG_NO_TSTP
|
|
Status: removed
|
|
Since: 1.15.6
|
|
Why:
|
|
Having two ways to let the administrator get to a shell on conffile prompt
|
|
is confusing, it also impedes setting up a consistent environment to be
|
|
used by external programs.
|
|
|
|
What: support for PGP
|
|
Status: removed
|
|
When: 1.16.4
|
|
Warning: program
|
|
Why:
|
|
PGP is not part of Debian and GnuPG has been the standard tool for digital
|
|
signatures for several years already. Supporting only GnuPG enables us to
|
|
rely on some of its features.
|
|
|
|
What: -u, --udeb (dpkg-scanpackages option)
|
|
Status: removed
|
|
When: 1.16.4
|
|
Warning: program
|
|
Why:
|
|
This option has been superseded by -tudeb.
|
|
|
|
What: support for custom changelog parsers as programs
|
|
Status: removed
|
|
Since: 1.18.8
|
|
Why:
|
|
Using programs to implement the custom changelog parsers was very inefficient
|
|
as it required to parse the custom changelog, output deb822 formatted entries
|
|
to then parse that and output again with the desired format.
|
|
.
|
|
These were implemented as programs because at the time the perl code in dpkg
|
|
was not using perl modules, so it was not easy to extend. Using perl modules
|
|
now is cleaner and allows for a faster implementation.
|
|
.
|
|
In addition there's no known users in Debian, so it was deemed safe to remove
|
|
the support without a transition.
|
|
|
|
What: Source-Version (substvar)
|
|
Status: removed
|
|
When: 1.18.11
|
|
Warning: program, lintian (substvar-source-version-is-deprecated)
|
|
Why:
|
|
The semantics of Source-Version were misleading when applied to binNMUs.
|
|
Should switch to use binary:Version or source:Version substvars.
|
|
.
|
|
The code got changed to emit errors.
|
|
|
|
What: -Zlzma (dpkg-deb option value)
|
|
Status: removed
|
|
When: 1.18.11
|
|
Warning: program
|
|
Why:
|
|
LZMA compression has some format deficiencies fixed by XZ, which is what
|
|
upstream has replaced it with, as such there's no point in continuing to
|
|
support compressing new .deb files with that format, although unpacking
|
|
will be kept being supported to handle existing compressed files.
|
|
|
|
What: -Zbzip2 (dpkg-deb option value)
|
|
Status: removed
|
|
When: 1.18.11
|
|
Warning: program
|
|
Why:
|
|
bzip2 compression has been superseded by xz when it comes to size, and
|
|
gzip is still faster, in Debian there's really not many packages using
|
|
that compression, as such there's no point in continuing to support
|
|
compressing new .deb files with that format, although unpacking
|
|
will be kept being supported to handle existing compressed files.
|
|
|
|
What: --new, --old (dpkg-deb options)
|
|
Status: removed
|
|
When: 1.18.11
|
|
Warning: program
|
|
Why:
|
|
These options are not future-proof, and do not give the caller any
|
|
guarantee of what exact format version will be used to produce the
|
|
output file. They were replaced with a new --deb-format option.
|
|
|
|
What: --print-installation-architecture (dpkg option)
|
|
Status: removed
|
|
When: 1.18.11
|
|
Warning: program
|
|
Why:
|
|
Obsoleted long time ago (2005-01-22). Remaining packages should switch to
|
|
use 'dpkg --print-architecture'.
|
|
|
|
What: GCJ and GCJFLAGS support
|
|
Status: removed
|
|
When: 1.22.1
|
|
Why:
|
|
GCJ has been dead upstream since 2018.
