Install-progress reporting

If the apt options APT::Status-Fd is set, apt will send status reports to that fd. The status information is separated with a ':', there are the following status conditions:

• pmstatus
• dlstatus
• conffile-prompt
• error
• media-change

The reason for using a fd instead of an OpProgress class is that many apt front-end fork a (vte) terminal for the actual installation.

The reason to do the mapping and l10n of the dpkg states to human readable (and translatable) strings is that this way the translation needs to be done only once for all front-ends.

pmstatus

Status of the package manager (dpkg). This is send when packages are installed/removed. pmstatus:pkgname:TotalPercentage:action-description

• PkgName = the name of the package
• TotalPercentage = the total progress between [0..100]
• description = a i18ned human readable description of the current action

Example:

# ./apt-get install -o APT::Status-Fd=2 3dchess >/dev/null
pmstatus:3dchess:20:Preparing 3dchess
pmstatus:3dchess:40:Unpacking 3dchess
pmstatus:3dchess:60:Preparing to configure 3dchess
pmstatus:3dchess:80:Configuring 3dchess
pmstatus:3dchess:100:Installed 3dchess

pmerror

pmerror:deb:TotalPercentage:error string

Example:

pmerror: /var/cache/apt/archives/krecipes_0.8.1-0ubuntu1_i386.deb : 75% : trying to overwrite `/usr/share/doc/kde/HTML/en/krecipes/krectip.png', which is also in package krecipes-data

pmconffile

pmconffile:conffile:percent:'current-conffile' 'new-conffile' useredited distedited
