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 This is unlikely to happen before 1.17.x. + +What --forget-old-unavail (dpkg option) +Status: obsolete +When: 1.16.x +Warning: program +Why: + Purged packages are properly cleaned up now by dpkg, and old unavailable + leftovers are automatically cleaned up on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(dpkg-query option) +Status: deprecated +When: 1.18.x +Warning: man page + This was a semi-public interface now superseded by --control-list and + --control-show, which are a better interface as they do not rely on any + specific database layout.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 + +What: -L (dpkg-parsechangelog option) +Status: obsolete +Since: 1.18.8 +When: 1.19.x +Warning: program +Why: + The custom parsers have been switched from programs to perl modules, + and this option has no use any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 + +What: recommended, contrib, base (priority) +Status: removed +When: 1.15.1 +Why: + These priorities have been superseded by either other fields or values in + other fields.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'. -- cgit v1.2.3
