+
+ Archive Extraction Directory Stream
+
+ Extraction for each file is a bit of an involved process. Each object
+ undergoes an atomic backup, overwrite, erase sequence. First the
+ object is unpacked to '.dpkg.new' then the original is hardlinked to
+ '.dpkg.tmp' and finally the new object is renamed to overwrite the old
+ one. From an external perspective the file never ceased to exist.
+ After the archive has been sucessfully unpacked the .dpkg.tmp files
+ are erased. A failure causes all the .dpkg.tmp files to be restored.
+
+ Decisions about unpacking go like this:
+ - Store the original filename in the file listing
+ - Resolve any diversions that would effect this file, all checks
+ below apply to the diverted name, not the real one.
+ - Resolve any symlinked configuration files.
+ - If the existing file does not exist then .dpkg-tmp is checked for.
+ [Note, this is reduced to only check if a file was expected to be
+ there]
+ - If the existing link/file is not a directory then it is replaced
+ irregardless
+ - If the existing link/directory is being replaced by a directory then
+ absolutely nothing happens.
+ - If the existing link/directory is being replaced by a link then
+ absolutely nothing happens.
+ - If the existing link/directory is being replaced by a non-directory
+ then this will abort if the package is not the sole owner of the
+ directory. [Note, this is changed to not happen if the directory
+ non-empty - that is, it only includes files that are part of this
+ package - prevents removing user files accidentally.]
+ - If the non-directory exists in the listing database and it
+ does not belong to the current package then an overwrite condition
+ is invoked.
+
+ As we unpack we record the file list differences in the FL cache. If
+ we need to unroll the the FL cache knows which files have been unpacked
+ and can undo. When we need to erase then it knows which files have not
+ been unpacked.

+ File Listing - Manages a Cache of File -> Package names.
+
+ Diversions add some signficant complexity to the system. To keep
+ storage space down in the very special case of a diverted file no
+ extra bytes are allocated in the Node structure. Instead a diversion
+ is inserted directly into the hash table and its flag bit set. Every
+ lookup for that filename will always return the diversion.
+
+ The hash buckets are stored in sorted form, with diversions having
+ the higest sort order. Identical files are assigned the same file
+ pointer, thus after a search all of the nodes owning that file can be
+ found by iterating down the bucket.
+
+ Re-updates of diversions (another extremely special case) are done by
+ marking all diversions as untouched, then loading the entire diversion
+ list again, touching each diversion and then finally going back and
+ releasing all untouched diversions. It is assumed that the diversion
+ table will always be quite small and be a very irregular case.
+
+ Diversions that are user-installed are represented by a package with
+ an empty name string.
+
+ Conf files are handled like diversions by changing the meaning of the
+ Pointer field to point to a conf file entry - again to reduce over
+ head for a special case.

+ System - Abstraction for running on different systems.
+
+ Instances of this class can be thought of as factories or meta-classes
+ for a variety of more specialized classes. Together this class and
+ it's speciallized offspring completely define the environment and how
+ to access resources for a specific system. There are several sub
+ areas that are all orthogonal - each system has a unique combination of
+ these sub areas:
+ - Versioning. Different systems have different ideas on versions.
+ Within a system all sub classes must follow the same versioning
+ rules.
+ - Local tool locking to prevent multiple tools from accessing the
+ same database.
+ - Candidate Version selection policy - this is probably almost always
+ managed using a standard APT class
+ - Actual Package installation
+ * Indication of what kind of binary formats are supported
+ - Selection of local 'status' indexes that make up the pkgCache.
+
+ It is important to note that the handling of index files is not a
+ function of the system. Index files are handled through a seperate
+ abstraction - the only requirement is that the index files have the
+ same idea of versioning as the target system.
+
+ Upon startup each supported system instantiates an instance of the
+ pkgSystem class (using a global constructor) which will make itself
+ available to the main APT init routine. That routine will select the
+ proper system and make it the global default.

+ The V4 engine allows the user to completly control all aspects of

+ * Selection by Release file match
+ * Selection by origin server
+
+ Each package may be 'pinned' with a single criteria, which will ultimately

+
+ Furthermore, the default selection can be influenced by specifying
+ the ordering of package files. The order is derived by reading the
+ package file preferences and assigning a priority to each package
+ file.
+
+ A special flag may be set to indicate if no version should be returned
+ if no matching versions are found, otherwise the default matching

+ Version Matching
+
+ This module takes a matching string and a type and locates the version
+ record that satisfies the constraint described by the matching string.
+
+ Version: 1.2*
+ Release: o=Debian,v=2.1*,c=main
+ Release: v=2.1*
+ Release: *
+ Origin: ftp.debian.org
+
+ Release may be a complex type that can specify matches for any of:
+ Version (v= with prefix)
+ Origin (o=)
+ Archive (a=)
+ Label (l=)
+ Component (c=)
+ If there are no equals signs in the string then it is scanned in short
+ form - if it starts with a number it is Version otherwise it is an
+ Archive.
+
+ Release may be a '*' to match all releases.

+ <RefSect1><Title>Description</>
+ <para>
+ <command/apt-cache/ performs a variety of operations on APT's package
+ cache. <command/apt-cache/ does not manipulate the state of the system
+ but does provide operations to search and generate interesting output
+ from the package metadata.
+
+ <para>
+ Unless the <option/-h/, or <option/--help/ option is given one of the
+ above commands must be present.
+
+ <VariableList>
+ <VarListEntry><Term>add</Term>
+ <ListItem><Para>
+ <literal/add/ adds the names package index files to the package cache.
+ </VarListEntry>
+
+ <VarListEntry><Term>gencaches</Term>
+ <ListItem><Para>
+ <literal/gencaches/ performs the same opration as
+ <command/apt-get check/. It builds the source and package caches from
+ the sources in &sources-list; and from <filename>/var/lib/dpkg/status</>.
+ </VarListEntry>
+
+ <VarListEntry><Term>showpkg</Term>
+ <ListItem><Para>
+ <literal/showpkg/ displays information about the packages listed on the
+ command line. Remaining arguments are package names. The available
+ versions and reverse dependencies of each package listed are listed, as
+ well as forward dependencies for each version. Forward (normal)
+ dependencies are those packages upon which the package in question
+ depends; reverse dependencies are those packages that depend upon the
+ package in question. Thus, forward dependencies must be satisfied for a
+ package, but reverse dependencies need not be.
+ For instance, <command>apt-cache showpkg libreadline2</> would produce
+ output similar to the following:
+
+<informalexample><programlisting>
+Package: libreadline2
+Versions: 2.1-12(/var/state/apt/lists/foo_Packages),
+Reverse Depends:
+ libreadlineg2,libreadline2
+ libreadline2-altdev,libreadline2
+Dependencies:
+2.1-12 - libc5 (2 5.4.0-0) ncurses3.0 (0 (null))
+Provides:
+2.1-12 -
+Reverse Provides:
+</programlisting></informalexample>
+
+ <para>
+ Thus it may be seen that libreadline2, version 2.1-8, depends on libc5,
+ ncurses3.0, and ldso, which must be installed for libreadline2 to work.
+ In turn, libreadlineg2 and libreadline2-altdev depend on libreadline2. If
+ libreadline2 is installed, libc5, ncurses3.0, and ldso must also be
+ installed; libreadlineg2 and libreadline2-altdev do not have to be
+ installed. For the specific meaning of the remainder of the output it
+ is best to consult the apt source code.
+ </VarListEntry>
+
+ <VarListEntry><Term>stats</Term>
+ <ListItem><Para>
+ <literal/stats/ displays some statistics about the cache.
+ No further arguments are expected. Statistics reported are:
+ <itemizedlist>
+ <listitem><para>
+ <literal/Total package names/ is the number of package names found
+ in the cache.
+ </listitem>
+
+ <listitem><para>
+ <literal/Normal packages/ is the number of regular, ordinary package
+ names; these are packages that bear a one-to-one correspondence between
+ their names and the names used by other packages for them in
+ dependencies. The majority of packages fall into this category.
+ </listitem>
+
+ <listitem><para>
+ <literal/Pure virtual packages/ is the number of packages that exist
+ only as a virtual package name; that is, packages only "provide" the
+ virtual package name, and no package actually uses the name. For
+ instance, "mail-transport-agent" in the Debian GNU/Linux system is a
+ pure virtual package; several packages provide "mail-transport-agent",
+ but there is no package named "mail-transport-agent".
+ </listitem>
+
+ <listitem><para>
+ <literal/Single virtual packages/ is the number of packages with only
+ one package providing a particular virtual package. For example, in the
+ Debian GNU/Linux system, "X11-text-viewer" is a virtual package, but
+ only one package, xless, provides "X11-text-viewer".
+ </listitem>
+
+ <listitem><para>
+ <literal/Mixed virtual packages/ is the number of packages that either
+ provide a particular virtual package or have the virtual package name
+ as the package name. For instance, in the Debian GNU/Linux system,
+ debconf is both an actual package, and provided by the debconf-tiny
+ package.
+ </listitem>
+
+ <listitem><para>
+ <literal/Missing/ is the number of package names that were referenced in
+ a dependency but were not provided by any package. Missing packages may
+ be in evidence if a full distribution is not accesssed, or if a package
+ (real or virtual) has been dropped from the distribution. Usually they
+ are referenced from Conflicts statements.
+ </listitem>
+
+ <listitem><para>
+ <literal/Total distinct/ versions is the number of package versions
+ found in the cache; this value is therefore at least equal to the
+ number of total package names. If more than one distribution (both
+ "stable" and "unstable", for instance), is being accessed, this value
+ can be considerably larger than the number of total package names.
+ </listitem>
+
+ <listitem><para>
+ <literal/Total dependencies/ is the number of dependency relationships
+ claimed by all of the packages in the cache.
+ </listitem>
+ </itemizedlist>
+ </VarListEntry>
+
+ <VarListEntry><Term>dump</Term>
+ <ListItem><Para>
+ <literal/dump/ shows a short listing of every package in the cache. It is
+ primarily for debugging.
+ </VarListEntry>
+
+ <VarListEntry><Term>dumpavail</Term>
+ <ListItem><Para>
+ <literal/dumpavail/ prints out an available list to stdout. This is
+ suitable for use with &dpkg; and is used by the &dselect; method.
+ </VarListEntry>
+
+ <VarListEntry><Term>unmet</Term>
+ <ListItem><Para>
+ <literal/unmet/ displays a summary of all unmet dependencies in the
+ package cache.
+ </VarListEntry>
+
+ <VarListEntry><Term>show</Term>
+ <ListItem><Para>
+ <literal/show/ performs a function similar to
+ <command>dpkg --print-avail</>, it displays the package records for the
+ named packages.
+ </VarListEntry>
+
+ <VarListEntry><Term>search</Term>
+ <ListItem><Para>
+ <literal/search/ performs a full text search on all available package
+ files for the regex pattern given. It searchs the package names and the
+ descriptions for an occurance of the string and prints out the package
+ name and the short description. If <option/--full/ is given then output
+ identical to <literal/show/ is produced for each matched package and
+ if <option/--names-only/ is given then the long description is not
+ searched, only the package name is.
+ <para>
+ Seperate arguments can be used to specified multiple search patterns that
+ are or'd together.
+ </VarListEntry>
+
+ <VarListEntry><Term>depends</Term>
+ <ListItem><Para>
+ <literal/depends/ shows a listing of each dependency a package has
+ and all the possible other packages that can fullfill that dependency.
+ </VarListEntry>
+
+ <VarListEntry><Term>pkgnames</Term>
+ <ListItem><Para>
+ This command prints the name of each package in the system. The optional
+ argument is a prefix match to filter the name list. The output is suitable
+ for use in a shell tab complete function and the output is generated
+ extremly quickly. This command is best used with the
+ <option/--generate/ option.
+ </VarListEntry>
+
+ <VarListEntry><Term>dotty</Term>
+ <ListItem><Para>
+ <literal/dotty/ takes a list of packages on the command line and
+ gernerates output suitable for use by dotty from the
+ <ulink url="http://www.research.att.com/sw/tools/graphviz/">GraphVis</>
+ package. The result will be a set of nodes and edges representing the
+ relationships between the packages. By default the given packages will
+ trace out all dependent packages which can produce a very large graph.
+ This can be turned off by setting the
+ <literal>APT::Cache::GivenOnly</> option.
+
+ <para>
+ The resulting nodes will have several shapse, normal packages are boxes,
+ pure provides are triangles, mixed provides are diamonds,
+ hexagons are missing packages. Orange boxes mean recursion was stopped

-bf(apt-cache) performs a variety of operations on APT's package cache.
-bf(apt-cache) is seldom called directly; instead its operations are
-performed automatically by the other bf(apt) utilities.
-

-itemize(
- it() add file1 [file2] [...]
- it() gencaches
- it() showpkg package1 [package2] [...]
- it() stats

- it() unmet

-
-Unless the -h, or --help option is given one of the above commands
-must be present.
-
-startdit()
-dit(bf(add))
-bf(add) adds the names package index files to the package cache.
-
-dit(bf(gencaches))
-bf(gencaches) performs the same opration as bf(apt-get check). It builds
-the source and package caches from thes sources in bf(/etc/apt/sources.list)
-and from bf(/var/lib/dpkg/status).
-
-dit(bf(showpkg))
-bf(showpkg) displays information about the packages listed on the
-command line. Remaining arguments are package names. The available versions
-and reverse dependencies of each package listed are listed, as well as
-forward dependencies for each version. Forward (normal) dependencies
-are those packages upon which the package in question depends; reverse
-dependencies are those packages that depend upon the package in
-question. Thus, forward dependencies must be satisfied for a package,
-but reverse dependencies need not be.
-For instance, bf(apt-cache showpkg libreadline2) would produce output similar
-to the following:
-
-verb(
-Package: libreadline2

-
-Reverse Provides:
-)
-
-Thus it may be seen that libreadline2, version 2.1-8, depends on libc5,
-ncurses3.0, and ldso, which must be installed for libreadline2 to work. In
-turn, libreadlineg2 and libreadline2-altdev depend on libreadline2. If
-libreadline2 is installed, libc5, ncurses3.0, and ldso must also be
-installed; libreadlineg2 and libreadline2-altdev do not have to be

-is best to consult the apt source code.
-
-dit(bf(stats))
-bf(stats) displays some statistics about bf(cache).
-No further arguments are expected. Statistics reported are:
-itemize(
- it() bf(Total package names) is the number of package names found in the cache.
-
- it() bf(Normal packages) is the number of regular, ordinary package names; these
- are packages that bear a one-to-one correspondence between their names and
- the names used by other packages for them in dependencies. The majority of
- packages fall into this category.
-
- it() bf(Pure virtual packages) is the number of packages that exist only as
- a virtual package name; that is, packages only "provide" the virtual
- package name, and no package actually uses the name. For instance,
- "mail-transport-agent" in the Debian GNU/Linux system is a pure virtual
- package; several packages provide "mail-transport-agent", but there is no
- package named "mail-transport-agent".
-
- it() bf(Single virtual packages) is the number of packages with only one
- package providing a particular virtual package. For example, in the
- Debian GNU/Linux system, "X11-text-viewer" is a virtual package, but only
- one package, xless, provides "X11-text-viewer".
-
- it() bf(Mixed virtual packages) is the number of packages that either provide
- a particular virtual package or have the virtual package name as the
- package name. For instance, in the Debian GNU/Linux system, e2fsprogs is
- both an actual package, and provided by the e2compr package.
-
- it() bf(Missing) is the number of package names that were referenced in a
- dependency but were not provided by any package. Missing packages may be
- in evidence if a full distribution is not accesssed, or if a package
- (real or virtual) has been dropped from the distribution.
-
- it() bf(Total distinct) versions is the number of package versions found in
- the cache; this value is therefore at least equal to the number of total
- package names. If more than one distribution (both "stable" and "unstable",
- for instance), is being accessed, this value can be considerably larger
- than the number of total package names.
-
- it() bf(Total dependencies) is the number of dependency relationships claimed
- by all of the packages in the cache.
-)
-
-dit(bf(dump))
-bf(dump) shows a short listing of every package in the cache. It is primarily
-for debugging.
-
-dit(bf(dumpavail))
-bf(dumpavail) prints out an available list to stdout. This is suitable for use
-with bf(dpkg) and is used by the bf(dselect) method.
-
-dit(bf(unmet))
-bf(unmet) displays a summary of all unmet dependencies in the package cache.
-
-dit(bf(check))
-bf(check) is a random function for testing certain aspects of the cache.
-Do not use it.
-
-dit(bf(showpkg))
-bf(showpkg) displays a listing of the given package cache structure and some
-related information about it. The list is meant primarily for debugging.
-
-dit(bf(show))
-bf(show) performs a function similar to dpkg --print-avail, it displays
-the package records for the named packages.
-
-dit(bf(search))
-bf(search) performs a full text search on all available package files for
-the pattern given. It searchs the package names and the descriptions for
-an occurance of the string and prints out the package name and the short
-description. If --full is given then output identical to bf(show) is produced
-for each matched package and if --names-only is given then the long
-description is not searched, only the package name is.
-
-dit(bf(depends))
-bf(depends) shows a listing of each dependency a package has and all
-the possible other packages that can fullfill that dependency.
-
-dit(bf(pkgnames))
-This command prints the name of each package in the system. The optional
-argument is a prefix match to filter the name list. The output is suitable
-for use in a shell tab complete function and the output is generated extremly
-quickly. This command is best used with the bf(--no-generate) option.
-
-dit(bf(dotty))
-bf(dotty) Takes a list of packages on the command line and gernerates output
-suitable for use by dotty from the GraphVis
-(http://www.research.att.com/sw/tools/graphviz/) package. The result will be
-a set of nodes and edges representing the relationships between the
-packages. By default the given packages will trace out all dependent packages
-which can produce a very large graph. This can be turned off by setting the
-APT::Cache::GivenOnly option.
-
-The resulting nodes will have several shapse, normal packages are boxes,
-pure provides are triangles, mixed provides are diamonds,
-hexagons are missing packages. Orange boxes mean recursion was stopped
-[leaf packages], blue lines are prre-depends, green lines are conflicts.
-
-Caution, dotty cannot graph larger sets of packages.
-
-enddit()
-
-manpageoptions()
-All command line options may be set using the configuration file, the
-descriptions indicate the configuration option to set. For boolean
-options you can override the config file by using something like bf(-f-),
-bf(--no-f), bf(-f=no) or several other variations.
-
-startdit()
-dit(bf(-h, --help))
-Show a short usage summary.
-
-dit(bf(-v, --version))
-Show the program verison.
-
-dit(bf(-p --pkg-cache))
-Select the file to store the package cache. The package cache is the primary
-cache used by all operations.
-Configuration Item: bf(Dir::Cache::pkgcache).
-
-dit(bf(-s --src-cache))
-Select the file to store the source cache. The source is used only by
-bf(gencaches) and it stores a parsed version of the package information from
-remote sources. When building the package cache the source cache is used
-to advoid reparsing all of the package files.
-Configuration Item: bf(Dir::Cache::srcpkgcache).
-
-dit(bf(-q, --quiet))
-Quiet; produces output suitable for logging, omitting progress indicators.
-More qs will produce more quite up to a maximum of 2. You can also use
-bf(-q=#) to set the quiet level, overriding the configuration file.
-Configuration Item: bf(quiet).
-
-dit(bf(-i --important))
-Print only important deps; for use with unmet causes only em(Depends) and
-em(Pre-Depends) relations to be printed.
-Configuration Item: bf(APT::Cache::Important).
-
-dit(bf(-f --full))
-Print full package records when searching. Configuration Item: bf(APT::Cache::ShowFull).
-
-dit(bf(-a --all-versions))
-Print full records for all available versions, this is only applicable to the
-show command. Configuration Item: bf(APT::Cache::AllVersions)
-
-dit(bf(-g --no-generate))
-Do not perform automatic package cache regeneration, use the cache as it is.
-Configuration Item: bf(APT::Cache::NoGenerate).
-
-dit(bf(--names-only))
-Only search on the package names, not the long description.
-Configuration Item: bf(APT::Cache::NamesOnly).
-
-dit(bf(--all-names))
-Make bf(pkgnames) print all names, including virtual packages and missing
-dependencies. Configuration Item: bf(APT::Cache::AllNames).

+ <para>
+ <command/apt-get/ is the command-line tool for handling packages, and may be
+ considered the user's "back-end" to other tools using the APT library.
+ <para>
+ Unless the <option/-h/, or <option/--help/ option is given one of the
+ above commands must be present.
+
+ <VariableList>
+ <VarListEntry><Term>update</Term>
+ <ListItem><Para>
+ <literal/update/ is used to resynchronize the package index files from
+ their sources. The indexes of available packages are fetched from the
+ location(s) specified in <filename>/etc/apt/sources.list</>.
+ For example, when using a Debian archive, this command retrieves and
+ scans the <filename>Packages.gz</> files, so that information about new
+ and updated packages is available. An <literal/update/ should always be
+ performed before an <literal/upgrade/ or <literal/dist-upgrade/. Please
+ be aware that the overall progress meter will be incorrect as the size
+ of the package files cannot be known in advance.
+ </VarListEntry>
+
+ <VarListEntry><Term>upgrade</Term>
+ <ListItem><Para>
+ <literal/upgrade/ is used to install the newest versions of all packages
+ currently installed on the system from the sources enumerated in
+ <filename>/etc/apt/sources.list</>. Packages currently installed with
+ new versions available are retrieved and upgraded; under no circumstances
+ are currently installed packages removed, or packages not already installed
+ retrieved and installed. New versions of currently installed packages that
+ cannot be upgraded without changing the install status of another package
+ will be left at their current version. An <literal/update/ must be
+ performed first so that <command/apt-get/ knows that new versions of packages are
+ available.
+ </VarListEntry>
+
+ <VarListEntry><Term>dselect-upgrade</Term>
+ <ListItem><Para>
+ is used in conjunction with the traditional Debian GNU/Linux packaging
+ front-end, &dselect;. <literal/dselect-upgrade/
+ follows the changes made by &dselect; to the <literal/Status/
+ field of available packages, and performs the actions necessary to realize
+ that state (for instance, the removal of old and the installation of new
+ packages).
+ </VarListEntry>
+
+ <VarListEntry><Term>dist-upgrade</Term>
+ <ListItem><Para>
+ <literal/dist-upgrade/, in addition to performing the function of
+ <literal/upgrade/, also intelligently handles changing dependencies
+ with new versions of packages; <command/apt-get/ has a "smart" conflict
+ resolution system, and it will attempt to upgrade the most important
+ packages at the expense of less important ones if necessary.
+ The <filename>/etc/apt/sources.list</> file contains a list of locations
+ from which to retrieve desired package files.
+ </VarListEntry>
+
+ <VarListEntry><Term>install</Term>
+ <ListItem><Para>
+ <literal/install/ is followed by one or more packages desired for
+ installation. Each package is a package name, not a fully qualified
+ filename (for instance, in a Debian GNU/Linux system, libc6 would be the
+ argument provided, not em(libc6_1.9.6-2.deb)). All packages required
+ by the package(s) specified for installation will also be retrieved and
+ installed. The <filename>/etc/apt/sources.list</> file is used to locate
+ the desired packages. If a hyphen is appended to the package name (with
+ no intervening space), the identified package will be removed if it is
+ installed. Similarly a plus sign can be used to designate a package to
+ isntall. These latter feature may be used to override decisions made by
+ apt-get's conflict resolution system.
+ <para>
+ A specific version of a package can be selected for installation by
+ following the package name with an equals and the version of the package
+ to select. This will cause that version to be located and selected for
+ install. Alternatively a specific distribution can be selected by
+ following the package name with a slash and the version of the
+ distribution or the Archive name (stable, frozen, unstable).
+ <para>
+ Both of the version selection mechansims can downgrade packages and must
+ be used with care.
+ <para>
+ If no package matches the given expression and the expression contains one
+ of '.', '?' or '*' then it is assumed to be a POSIX regex and it is applied
+ to all package names in the database. Any matches are then installed (or
+ removed). Note that matching is done by substring so 'lo.*' matches 'how-lo'
+ and 'lowest'. If this is undesired prefix with a '^' character.
+ </VarListEntry>
+
+ <VarListEntry><Term>remove</Term>
+ <ListItem><Para>
+ <literal/remove/ is identical to bf(install) except that packages are
+ removed instead of installed. If a plus sign is appended to the package
+ name (with no intervening space), the identified package will be
+ installed.
+ </VarListEntry>
+
+ <VarListEntry><Term>source</Term>
+ <ListItem><Para>
+ <literal/source/ causes <command/apt-get/ to fetch source packages. APT
+ will examine the available packages to decide which source package to
+ fetch. It will then find and download into the current directory the
+ newest available version of that source package. Source packages are
+ tracked separately from binary packages via <literal/deb-src/ type lines
+ in the &sources-list; file. This probably will mean that you will not
+ get the same source as the package you have installed or as you could
+ install. If the --compile options is specified then the package will be
+ compiled to a binary .deb using dpkg-buildpackage, if --download-only is
+ specified then the source package will not be unpacked.
+ <para>
+ A specific source version can be retrieved by postfixing the source name
+ with an equals and then the version to fetch, similar to the mechanism
+ used for the package files. This enables exact matching of the source
+ package name and version, implicitly enabling the
+ <literal/APT::Get::Only-Source/ option.
+
+ <para>
+ Note that source packages are not tracked like binary packages, they
+ exist only in the current directory and are similar to downloading source
+ tar balls.
+ </VarListEntry>
+
+ <VarListEntry><Term>build-dep</Term>
+ <ListItem><Para>
+ <literal/build-dep/ causes apt-get to install/remove packages in an
+ attempt to satisfy the build dependencies for a source packages. Right
+ now virtual package build depends choose a package at random.
+ </VarListEntry>
+
+ <VarListEntry><Term>check</Term>
+ <ListItem><Para>
+ <literal/check/ is a diagnostic tool; it updates the package cache and checks
+ for broken dependencies.
+ </VarListEntry>
+
+ <VarListEntry><Term>clean</Term>
+ <ListItem><Para>
+ <literal/clean/ clears out the local repository of retrieved package
+ files. It removes everything but the lock file from
+ <filename>&cachedir;/archives/</> and
+ <filename>&cachedir;/archive/partial/</>. When APT is used as a
+ &dselect; method, <literal/clean/ is run automatically.
+ Those who do not use dselect will likely want to run <literal/apt-get clean/
+ from time to time to free up disk space.
+ </VarListEntry>
+
+ <VarListEntry><Term>autoclean</Term>
+ <ListItem><Para>
+ Like <literal/clean/, <literal/autoclean/ clears out the local
+ repository of retrieved package files. The difference is that it only
+ removes package files that can no longer be downloaded, and are largely
+ useless. This allows a cache to be maintained over a long period without
+ it growing out of control. The configuration option
+ <literal/APT::Clean-Installed/ will prevent installed packages from being
+ erased if it is set off.

-manpagename(apt-get)(APT package handling utility -- command-line interface)
-
-manpagesynopsis()
- apt-get [options] [command] [package ...]
-
-manpagedescription()
-
-apt-get is the command-line tool for handling packages, and may be considered
-the user's "back-end" to apt(8).
-
-em(command) is one of:
-itemize(
- it() update
- it() upgrade
- it() dselect-upgrade
- it() dist-upgrade
- it() install package1 [package2] [...]
- it() remove package1 [package2] [...]
- it() source package1 [package2] [...]
- it() check
- it() clean
- it() autoclean
-)
-
-Unless the -h, or --help option is given one of the above commands
-must be present.
-
-startdit()
-dit(bf(update))
-bf(update) is used to resynchronize the package overview files from their
-sources. The overviews of available packages are fetched from the
-location(s) specified in bf(/etc/apt/sources.list).
-For example, when using a Debian archive, this command retrieves and
-scans the bf(Packages.gz) files, so that information about new and updated
-packages is available. An bf(update) should always be performed before an
-bf(upgrade) bf(dist-upgrade). Please be aware that the overall progress
-meter will be incorrect as the size of the package files cannot be known in
-advance.
-
-dit(bf(upgrade))
-bf(upgrade) is used to install the newest versions of all packages currently
-installed on the system from the sources enumerated in
-bf(/etc/apt/sources.list). Packages currently installed with new versions
-available are retrieved and upgraded; under no circumstances are currently
-installed packages removed, or packages not already installed retrieved and
-installed. New versions of currently installed packages that cannot be
-upgraded without changing the install status of another package will be left
-at their current version. An bf(update) must be performed first so that
-bf(apt-get) knows that new versions of packages are available.
-
-dit(bf(dselect-upgrade))
-bf(dselect-upgrade)
-is used in conjunction with the traditional Debian GNU/Linux packaging
-front-end, bf(dselect (8)). bf(dselect-upgrade)
-follows the changes made by bf(dselect) to the em(Status)
-field of available packages, and performs the actions necessary to realize
-that state (for instance, the removal of old and the installation of new
-packages).
-
-dit(bf(dist-upgrade))
-bf(dist-upgrade),in addition to performing the function of bf(upgrade),
-also intelligently handles changing dependencies with new versions of
-packages; bf(apt-get) has a "smart" conflict resolution system, and it will
-attempt to upgrade the most important packages at the expense of less
-important ones if necessary. The bf(/etc/apt/sources.list) file contains a
-list of locations from which to retrieve desired package files.
-
-dit(bf(install))
-bf(install) is followed by one or more em(packages) desired for installation.
-Each em(package) is a package name, not a fully qualified filename
-(for instance, in a Debian GNU/Linux system, em(ldso) would be the argument
-provided, not em(ldso_1.9.6-2.deb)). All packages required by the package(s)
-specified for installation will also be retrieved and installed. The
-bf(/etc/apt/sources.list) file is used to locate the desired packages. If a
-hyphen is appended to the package name (with no intervening space), the
-identified package will be removed if it is installed. This latter feature
-may be used to override decisions made by apt-get's conflict resolution system.
-
-If no package matches the given expression and the expression contains one
-of '.', '?' or '*' then it is assumed to be a POSIX regex and it is applied
-to all package names in the database. Any matches are then installed (or
-removed). Note that matching is done by substring so 'lo*' matches 'how-lo'
-and 'lowest'. If this is undesired prefix with a '^' character.
-
-dit(bf(remove))
-bf(remove) is identical to bf(install) except that packages are removed
-instead of installed. If a plus sign is appended to the package name (with no
-intervening space), the identified package will be installed.
-
-dit(bf(source))
-bf(source) causes apt-get to fetch source packages. APT will examine the
-available packages to decide which source package to fetch. It will then
-find and download into the current directory the newest available version of
-that source package. Source packages are tracked separately from binary
-packages via bf(deb-src) type lines in the bf(/etc/apt/sources.list) file.
-This probably will mean that you will not get the same source as the package
-you have installed or as you could install. If the --compile options is
-specified then the package will be compiled to a binary .deb using
-dpkg-buildpackage, if --download-only is specified then the source package
-will not be unpacked.
-
-Note that source packages are not tracked like binary packages, they exist
-only in the current directory and are similar to downloading source
-tar balls.
-
-dit(bf(check))
-bf(check) is a diagnostic tool; it updates the package cache and checks for
-broken packages.
-
-dit(bf(clean))
-bf(clean) clears out the local repository of retrieved package files. It
-removes everything but the lock file from bf(/var/cache/apt/archives/)
-and bf(/var/cache/apt/archives/partial/).
-When APT is used as a bf(dselect(8)) method, bf(clean) is run automatically.
-Those who do not use dselect will likely want to run code(apt-get clean)
-from time to time to free up disk space.
-
-dit(bf(autoclean))
-Like bf(clean), bf(autoclean) clears out the local repository of retrieved
-package files. The difference is that it only removes package files that
-can no longer be downloaded, and are largely useless. This allows a
-cache to be maintained over a long period without it growing out of
-control.
-
-enddit()
-
-manpageoptions()
-All command line options may be set using the configuration file, the
-descriptions indicate the configuration option to set. For boolean
-options you can override the config file by using something like bf(-f-),
-bf(--no-f), bf(-f=no) or several other variations.
-
-startdit()
-dit(bf(-d, --download-only))
-Download only; package files are only retrieved, not unpacked or installed.
-Configuration Item: bf(APT::Get::Download-Only).
-
-dit(bf(-f, --fix-broken))
-Fix; attempt to correct a system with broken dependencies in
-place. This option, when used with install/remove, can omit any packages
-to permit APT to deduce a likely soltion. Any Package that are specified
-must completly correct the problem. The option is sometimes necessary when
-running APT for the first time; APT itself does not allow broken package
-dependencies to exist on a system. It is possible that a system's
-dependency structure can be so corrupt as to require manual intervention
-(which usually means using dselect or dpkg --remove to eliminate some of
-the offending packages). Use of this option together with -m may produce an
-error in some situations. Configuration Item: bf(APT::Get::Fix-Broken).
-
-dit(bf(-h, --help))
-Help; display a helpful usage message and exits.
-
-dit(bf(-v, --version))
-Show the program version.
-
-dit(bf(-m, --ignore-missing, --fix-missing))
-Ignore missing packages; If packages cannot be retrieved or fail the
-integrity check after retrieval (corrupted package files), hold back
-those packages and handle the result. Use of this option together with
--f may produce an error in some situations. If a package is selected for
-installation (particularly if it is mentioned on the command line) and it
-could not be downloaded then it will be silently held back.
-Configuration Item: bf(APT::Get::ignore-missing).
-
-dit(bf(--no-download))
-Disables downloading of packages. This is best used with --ignore-missing to
-force APT to use only the .debs it has already downloaded.
-Configuration Item: bf(APT::Get::No-Download).
-
-dit(bf(-q, --quiet))
-Quiet; produces output suitable for logging, omitting progress indicators.
-More q's will produce more quiet up to a maximum of 2. You can also use
-bf(-q=#) to set the quiet level, overriding the configuration file. Note that
-quiet level 2 implies -y, you should never use -qq without a no-action
-modifier such as -d, --print-uris or -s as APT may decided to do something
-you did not expect.
-Configuration Item: bf(quiet)
-
-dit(bf(-s, --simulate, --just-print, --dry-run, --recon, --no-act))
-No action; perform a simulation of events that would occur but do not
-actually change the system. Configuration Item: bf(APT::Get::Simulate).
-
-Simulate prints out
-a series of lines each one representing a dpkg operation, Configure (Conf),
-Remove (Remv), Unpack (Inst). Square brackets indicate broken packages with
-and empty set of square brackets meaning breaks that are of no consequence
-(rare).
-
-dit(bf(-y, --yes, --assume-yes))
-Automatic yes to prompts; assume "yes" as answer to all prompts and run
-non-interactively. If an undesirable situation, such as changing a held
-package or removing an essential package occurs then bf(apt-get) will
-abort. Configuration Item: bf(APT::Get::Assume-Yes).
-
-dit(bf(-u, --show-upgraded))
-Show upgraded packages; Print out a list of all packages that are to be
-upgraded. Configuration Item: bf(APT::Get::Show-Upgraded).
-
-dit(bf(-b, --compile, --build))
-Compile source packages after downloading them.
-Configuration Item: bf(APT::Get::Compile).
-
-dit(bf(--ignore-hold))
-Ignore package Holds; This causes bf(apt-get) to ignore a hold placed on
-a package. This may be useful in conjunction with bf(dist-upgrade) to
-override a large number of undesired holds. Configuration Item: bf(APT::Ignore-Hold).
-
-dit(bf(--no-upgrade))
-Do not upgrade packages; When used in conjunction with bf(install)
-bf(no-upgrade) will prevent packages listed from being upgraded if they
-are already installed. Configuration Item: bf(APT::Get::no-upgrade).
-
-dit(bf(--force-yes))
-Force yes; This is a dangerous option that will cause apt to continue without
-prompting if it is doing something potentially harmful. It should not be used
-except in very special situations. Using bf(force-yes) can potentially destroy
-your system! Configuration Item: bf(APT::Get::force-yes).
-
-dit(bf(--print-uris))
-Instead of fetching the files to install their URIs are printed. Each
-URI will have the path, the destination file name, the size and the expected
-md5 hash. Note that the file name to write to will not always match
-the file name on the remote site! This also works with the bf(source)
-command. Configuration Item: bf(APT::Get::Print-URIs).
-
-dit(bf(--purge))
-Use purge instead of remove for anything that would be removed.
-Configuration Item: bf(APT::Get::Purge).
-
-dit(bf(--reinstall))
-Re-Install packages that are already installed and at the newest version.
-
-dit(bf(--list-cleanup))
-This option defaults to on, use bf(--no-list-cleanup) to turn it off.
-When on apt-get will automatically manage the contents of
-/var/state/apt/lists to ensure that obsolete files are erased. The only
-reason to turn it off is if you frequently change your source list.
-Configuration Item: bf(APT::Get::List-Cleanup)
-
-dit(bf(--trivial-only))
-Only perform operations are 'trivial'. Logically this can be considered
-related to --assume-yes, where --assume-yes will answer yes to any prompt,
---trivial-only will answer no. Configuration Item: bf(APT::Get::Trivial-Only)
-
-dit(bf(--no-remove))
-If any packages are to be removed apt-get immediately aborts without

+ <para>
+ <filename/apt.conf/ is the main configuration file for the APT suite of
+ tools, all tools make use of the configuration file and a common command line
+ parser to provide a uniform environment. When an APT tool starts up it will
+ read the configuration specified by the <envar/APT_CONFIG/ environment
+ variable (if any) and then read the files in <literal/Dir::Etc::Parts/
+ then read the main configuration file specified by
+ <literal/Dir::Etc::main/ then finally apply the
+ command line options to override the configuration directives, possibly
+ loading even more config files.
+ <para>
+ The configuration file is organized in a tree with options organized into
+ functional groups. Option specification is given with a double colon
+ notation, for instance <literal/APT::Get::Assume-Yes/ is an option within
+ the APT tool group, for the Get tool. Options do not inherit from their
+ parent groups.
+ <para>
+ Syntacticly the configuration language is modeled after what the ISC tools
+ such as bind and dhcp use. Each line is of the form
+ <literallayout>APT::Get::Assume-Yes "true";</literallayout> The trailing
+ semicolon is required and the quotes are optional. A new scope can be
+ opened with curly braces, like:
+<informalexample><programlisting>
+APT {
+ Get {
+ Assume-Yes "true";
+ Fix-Broken "true";
+ };
+};
+</programlisting></informalexample>
+ with newlines placed to make it more readable. Lists can be created by
+ opening a scope and including a single word enclosed in quotes followed by a
+ semicolon. Multiple entries can be included, each seperated by a semicolon.
+<informalexample><programlisting>
+DPkg::Pre-Install-Pkgs {"/usr/sbin/dpkg-preconfigure --apt";};
+</programlisting></informalexample>
+ <para>
+ In general the sample configuration file in

+ is a good guide for how it should look.
+ <para>
+ Two specials are allowed, <literal/#include/ and <literal/#clear/.
+ <literal/#include/ will include the given file, unless the filename
+ ends in a slash, then the whole directory is included.
+ <literal/#clear/ is used to erase a list of names.
+ <para>
+ All of the APT tools take a -o option which allows an arbitary configuration
+ directive to be specified on the command line. The syntax is a full option
+ name (<literal/APT::Get::Assume-Yes/ for instance) followed by an equals
+ sign then the new value of the option. Lists can be appended too by adding
+ a trailing :: to the list name.

+
+ <VarListEntry><Term>Immediate-Configure</Term>
+ <ListItem><Para>
+ Disable Immedate Configuration; This dangerous option disables some

-manpagename(apt.conf)(configuration file for APT)
-
-manpagedescription()
-bf(apt.conf) is the main configuration file for the APT suite of
-tools, all tools make use of the configuration file and a common command line
-parser to provide a uniform environment. When an APT tool starts up it will
-read bf(/etc/apt/apt.conf), then read the configuration specified by the
-bf($APT_CONFIG) environment variable and then finally apply the command line
-options to override the configuration directives, possibly loading more
-config files.
-
-The configuration file is organized in a tree with options organized into
-functional groups. Option specification is given with a double colon
-notation, for instance em(APT::Get::Assume-Yes) is an option within the
-APT tool group, for the Get tool. Options do not inherit from their parent
-groups.
-
-Syntacticly the configuration language is modeled after what the ISC tools
-such as bind and dhcp use. Each line is of the form
-quote(APT::Get::Assume-Yes "true";) The trailing semicolon is required and
-the quotes are optional. A new em(scope) can be opened with curly braces,
-like:
-verb(APT {
- Get {
- Assume-Yes "true";
- Fix-Broken "true";
- };
-};
-)
-with newlines placed to make
-it more readable. Lists can be created by opening a scope an including a
-single word enclosed in quotes followed by a semicolon.
-In general the sample configuration file in
-em(/usr/doc/apt/examples/apt.conf) and
-em(/usr/doc/apt/examples/configure-index)
-is a good guide for how it should look.
-
-All of the APT tools take a -o option which allows an arbitary configuration
-directive to be specified on the command line. The syntax is a full option
-name (APT::Get::Assume-Yes for instance) followed by an equals sign then the
-new value of the option. Lists can be appended too by adding a trailing ::
-to the list name.
-
-manpagesection(The APT Group)
-This group of options controls general APT behavoir as well as holding the
-options for all of the tools.
-
-startdit()
-dit(bf(Architecture))
-System Architecture; sets the architecture to use when fetching files and
-parsing package lists. The internal default is the architecture apt was
-compiled for.
-
-dit(bf(Ignore-Hold))
-Ignore Held packages; This global options causes the problem resolver to
-ignore held packages in its decision making.
-
-dit(bf(Clean-Installed))
-Defaults to on. When turned on the autoclean feature will remove any pacakge
-which can no longer be downloaded from the cache. If turned off then
-packages that are locally installed are also excluded from cleaning - but
-note that APT provides no direct means to reinstall them.
-
-dit(bf(Immediate-Configure))
-Disable Immedate Configuration; This dangerous option disables some
-of APT's ordering code to cause it to make fewer dpkg calls. Doing
-so may be necessary on some extremely slow single user systems but
-is very dangerous and may cause package install scripts to fail or worse.
-Use at your own risk.

+
+ <RefSect1><Title>Description</>
+ <para>
+ The APT preferences file controls various aspects of the APT system.
+ It is ment to be user editable and manipulatable from software. The file
+ consists of a number of records formed like the dpkg status file, space
+ seperated sections of text with at the start of each line tags seperated
+ by a colon. It is stored in <filename>/etc/apt/preferences</>.
+ </RefSect1>
+
+ <RefSect1><Title>Versioning</>
+ <para>
+ One purpose of the preferences file is to let the user select which version
+ of a package will be installed. This selection can be made in a number of
+ ways that fall into three categories, version, release and origin.
+ <para>
+ Selection by version can be done by exact match or prefix match. The format
+ is <literal/2.1.2/ or <literal/2.2*/ for a prefix match. Matching by prefix
+ can be used to ignore the <literal/r/ in the Debian release versioning, like
+ <literal/2.1r*/ or to ignore Debian specific revisions, <literal/1.1-*/.
+ When matching versions with a prefix the highest matching version will
+ always be picked.
+ <para>
+ Selection by release is more complicated and has three forms. The primary
+ purpose of release selections is to identify a set of packages that match
+ a specific vendor, or release (ie Debian 2.1). The first two forms are
+ shortcuts intended for quick command line use. If the first character of the
+ specification is a digit then it is considered to be a release version match,
+ otherwise a release label match. Specifications which contain equals are
+ full release data matches and are a comma seperated list of one letter keys
+ followed by an equals then by the string. Examples:
+<informalexample><programlisting>
+v=2.1*,o=Debian,c=main
+l=Debian
+a=stable
+</programlisting></informalexample>
+ <para>
+ The data for these matches are taken from the <filename/Release/ files
+ that APT downloads during an <literal/update/. The available keys are:
+ <VariableList>
+ <VarListEntry><term>a= Archive</term>
+ <ListItem><Para>
+ This is the common name we give our archives, such as <literal/stable/ or
+ <literal/unstable/. The special name <literal/now/ is used to designate
+ the set of packages that are currently installed.
+ </VarListEntry>
+
+ <VarListEntry><term>c= Component</term>
+ <ListItem><Para>
+ Referes to the sub-component of the archive, <literal/main/,
+ <literal/contrib/ etc. Component may be omitted if there are no
+ components for this archive.
+ </VarListEntry>
+
+ <VarListEntry><term>v= Version</term>
+ <ListItem><Para>
+ This is a version string with the same properties as in the Packages file.
+ It represents the release level of the archive. Typical Debian release
+ numbers look like <literal/2.1r2/ with the r designating the release of
+ 2.1. New releases are limited to security updates.
+ </VarListEntry>
+
+ <VarListEntry><term>o= Origin</term>
+ <ListItem><Para>
+ This specifies who is providing this archive. In the case of Debian the
+ string will read <literal/Debian/. Other providers may use their own
+ string.
+ </VarListEntry>
+
+ <VarListEntry><term><term>l= Label</term>
+ <ListItem><Para>
+ This carries the encompassing name of the distribution. For Debian proper
+ this field reads <literal/Debian/. For derived distributions it should
+ contain their proper name.
+ </VarListEntry>
+ </VariableList>
+ <para>
+ The final selection method is by origin. This is simply the site name
+ of the originating package files. The empty string is used for file URIs.
+ <para>
+ Version selection, particularly the latter two methods, are used in may
+ different part of APT, not just the preferences file.
+ </RefSect1>
+
+ <RefSect1><Title>Candidate Version Policy</>
+ <para>
+ Interaly APT maintains a list of all available versions for all packages.
+ If you place multiple releases or vendors in your &sources-list; file then
+ these features are available. By default APT selects the highest version
+ from all automatic sources. Some sources, such as
+ <filename>project/experimental</> are marked Not Automatic - these fall
+ to the bottom of the selection pile.
+ <para>
+ When deciding what version to use APT assigns a priority to each available
+ version of the package. It then does two things, first it selects
+ the highest priorty version that is newer than the installed version of the
+ package, then it selects the highest priority version that is older than
+ the installed version. Next, if the older versions have a priority greater
+ than 1000 they are compared with the priority of the upgrade set, the larger
+ becomes the selected result. Otherwise the downgrade versions are ignored
+ and the highest priority of the ugprade set is selected.
+ <para>
+ It is possible to think of the priorities in strata:
+ <VariableList>
+ <VarListEntry><term>1000 and up</term>
+ <ListItem><Para>
+ Downgradable priorities
+ </VarListEntry>
+
+ <VarListEntry><term>1000</term>
+ <ListItem><Para>
+ The downgrade prevention barrier
+ </VarListEntry>
+
+ <VarListEntry><term>100 to 1000</term>
+ <ListItem><Para>
+ Standard priorities. 990 is the priority set by the
+ <option/--target-release / &apt-get; option. 989 is the start for auto
+ priorities and 500 are all the default package files.
+ </VarListEntry>
+
+ <VarListEntry><term>100</term>
+ <ListItem><Para>
+ The currently installed version
+ </VarListEntry>
+
+ <VarListEntry><term>0 to 100</term>
+ <ListItem><Para>
+ Non automatic priorities. These are only used if the package
+ is not installed and there is no other version available.
+ </VarListEntry>
+
+ <VarListEntry><term>less than 0</term>
+ <ListItem><Para>
+ The version is never selected.
+ </VarListEntry>
+ </VariableList>
+ <para>
+ Giving a pin a priority greater than 1000 will allow APT to downgrade
+ in order to get to that version.
+ <para>
+ Each package may be pinned to a specific version and each Package file
+ has a priority for every package inside. The highest priority assigned
+ to a package is the one that is used.
+ <para>
+ A package pin looks like this:
+<informalexample><programlisting>
+Package: apt
+Pin: version 0.4.0
+Pin-Priority: 1001
+</programlisting></informalexample>
+ The first line specifies the package, the second gives the Pin specification
+ and the last gives the priority of this pin. The first word of the pin
+ specification may be version, release or origin, the remainder of the field
+ is described in the Versioning sectin above.
+ <para>
+ A default pin is how the priorities of package files are set. Any number
+ of default pins may be specified, the first matching default will select
+ the priority of the package file. Only release or origin may be used in
+ the Pin specification since they match Package files.
+<informalexample><programlisting>
+Package: *
+Pin: release v=2.1*
+Pin-Priority: 998
+</programlisting></informalexample>
+ <para>
+ If the Pin-Priorty field is omitted then the priority defaults to 989 for
+ both cases.
+
+ <RefSect2><title>Interesting Effects</>
+ <para>
+ Due to the downgrade prevention barrier at priority 1000 it is possible
+ that a lower priority version will be selected if the higher priority
+ would casue a downgrade. For instance, if package foo has versions
+ <literal/1.2/, <literal/1.1/ and <literal/1.0/ installed, with
+ <literal/1.1/ being the currently installed version and the priorities of
+ each version being 900, 100 and 950 repectively the winning version will be
+ <literal/1.2/.
+ <para>
+ In practice this is often desired. A user may use a default pin to
+ make the stable distribution the default and then use the
+ <option/--target-dist/ option with &apt-get; to select newer versions
+ from unstable. The packages that have been upgraded to unstable will
+ continue to follow the versions that are available in unstable since
+ the stable versions now fall below the downgrade prevention barrier.
+ <para>
+ If this is not desired then a default pin should be used to make unstable
+ have a priority less than 100.
+ <para>
+ Users of 3rd party add ons such as Helix GNOME can use this mechanism to
+ force the usage of Helix packages, or force the usage of Debian packages
+ by setting the priority of that source sufficiently high. It is even
+ possible to mass downgrade from one set of packages to another by
+ using a priority larger than 1000.

+<chapt>Descrizione generale
+
+<p>
+Il pacchetto APT al momento contiene due sezioni, il metodo APT
+<prgn>dselect</> e l'interfaccia utente a linea di comando <prgn>apt-get</>;
+entrambi danno modo di installare e rimuovere pacchetti, e di scaricarne
+altri da Internet.
+
+<sect>Anatomia del sistema di pacchettizzazione
+<p>
+Il sistema di pacchettizzazione di Debian contiene un gran numero di
+informazioni associate a ciascun pacchetto, per assicurarsi che si
+integri facilmente ed in maniera pulita nel sistema; la più
+importante di esse è il sistema di dipendenze.
+
+<p>
+Il sistema di dipendenze permette ai singoli programmi di fare uso
+degli elementi condivisi del sistema, quali le librerie; per
+ridurre il numero di elementi che l'utente medio debba installare,
+le porzioni di programmi che non vengono usate spesso vengono poste
+in pacchetti separati. Inoltre, è possibile avere più di una scelta per
+cose quali i programmi di posta elettronica, i server X e così via.
+
+<p>
+Il primo passo per capire il sistema di dipendenze è la
+comprensione del concetto di dipendenza semplice: un pacchetto richiede
+che un altro sia installato insieme ad esso per poter
+funzionare.
+
+
+<p>
+Ad esempio, mail-crypt è un'estensione di emacs che aiuta a criptare le
+mail con PGP. Se PGP non è installato, mail-crypt è inutile, quindi
+mail-crypt ha una dipendenza semplice da PGP. Inoltre, dato che si tratta
+di un'estensione di emacs, mail-crypt dipende anche da emacs, senza il
+quale è totalmente inutile.
+
+<p>
+L'altro tipo di dipendenza importante da capire è la dipendenza di
+conflitto; con questa, un pacchetto che venga installato insieme ad un
+altro pacchetto non funziona, e si hanno seri problemi al sistema.
+Come esempio, si consideri un programma di trasporto della posta,
+quale sendmail, exim o qmail: non è possibile averne due contemporaneamente,
+perché entrambi hanno bisogno di restare in ascolto sulla stessa porta di rete
+per ricevere la posta. Tentare di installarne due danneggerebbe seriamente il
+sistema, quindi ciascun programma di trasporto della posta ha una
+dipendenza di conflitto con tutti gli altri.
+
+<p>
+Come ulteriore complicazione, c'è la possibilità che un pacchetto
+voglia prendere il posto di un altro; ad esempio, exim e sendmail per molte
+cose sono identici, dato che entrambi gestiscono la posta e comprendono
+un'interfaccia comune, quindi il sistema di pacchettizzazione deve dichiarare
+che sono entrambi agenti di trasporto della posta, e che gli altri
+pacchetti a cui serve uno dei due devono dipendere da un pacchetto
+fittizio agente-di-trasporto-della-posta. Quando si modificano
+a mano i pacchetti, questo può portare a moltissima confusione.
+
+<p>
+In ciascun momento una singola dipendenza può essere soddisfatta o meno
+dai pacchetti già installati; APT cerca di risolvere i problemi
+di dipendenze con un buon numero di algoritmi automatici, che aiutano
+a selezionare i pacchetti da installare.

+<chapt>apt-get
+
+<p>
+<prgn>apt-get</> fornisce un modo semplice di installare i pacchetti dalla
+linea di comando. Diversamente da <prgn>dpkg</>, <prgn>apt-get</> non
+capisce i nomi dei file .deb, ma utilizza il vero nome dei pacchetti,
+e può installare archivi .deb solo da una fonte.
+
+<p>
+La prima <footnote>Se state usando un proxy server http, dovete prima ancora
+impostare la variabile d'ambiente http_proxy; vedere
+sources.list(5).</footnote>
+cosa da fare prima di usare <prgn>apt-get</> è impostare l'elenco dei
+pacchetti dalle fonti in modo che il programma sappia quali pacchetti
+sono disponibili. Lo si fa con <tt>apt-get update</>. Ad esempio,
+
+<p>
+<example>
+# apt-get update
+Get http://ftp.de.debian.org/debian-non-US/ stable/binary-i386/ Packages
+Get http://llug.sep.bnl.gov/debian/ frozen/contrib Packages
+Reading Package Lists... Done
+Building Dependency Tree... Done
+</example>
+
+<p>
+Dopo aver aggiornato l'elenco si possono usare molti comandi:
+<taglist>
+<tag>upgrade<item>
+Upgrade tenterà di fare un aggiornamento indolore del sistema completo,
+senza installare nuovi pacchetti o rimuoverne di esistenti, e senza
+aggiornare un pacchetto che possa rovinarne altri. Upgrade farà un elenco
+di tutti i pacchetti che non avrà potuto aggiornare, cosa che in genere
+significa che questi dipendono da nuovi pacchetti o vanno in conflitto
+con altri. Per forzare la loro installazione si può usare
+<prgn>dselect</> o <tt>apt-get install</>.
+
+<tag>install<item>
+Install viene usato per installare i singoli pacchetti dando il loro nome.
+Il pacchetto viene automaticamente scaricato ed installato, cosa molto utile
+se già se ne conosce il nome e non si vuole entrare in grafica per
+selezionarlo. Al comando si possono passare anche più pacchetti, che saranno
+tutti scaricati. L'installazione automatica cerca di risolvere i problemi
+di dipendenze con gli altri pacchetti elencati, stampa un riassunto e
+chiede conferma se si devono modificare altri pacchetti che non siano quelli
+sulla linea di comando.
+
+<tag>dist-upgrade<item>
+Dist-upgrade fa un aggiornamento completo, progettato in modo da rendere
+semplici gli aggiornamenti tra versioni di Debian. Usa un algoritmo
+sofisticato per determinare il miglior insieme di pacchetti da installare,
+aggiornare e rimuovere per arrivare alla versione più aggiornata
+del sistema possibile. In alcune situazioni può essere vantaggioso usare
+dist-upgrade invece che sprecare tempo a risolvere manualmente le
+dipendenze con <prgn>dselect</>. Una volta completato dist-upgrade, si può
+usare <prgn>dselect</> per installare eventuali pacchetti che sono stati
+tralasciati.
+
+<p>
+È importante controllare attentamente cosa intende fare dist-upgrade,
+dato che le sue decisioni a volte possono essere abbastanza sorprendenti.
+</taglist>
+
+<p>
+<prgn>apt-get</> ha diverse opzioni a linea di comando, che vengono
+documentate dettagliatamente nella sua pagina man,
+<manref name="apt-get" section="8">. L'opzione più utile è
+<tt>-d</>, che non installa i file scaricati: se il sistema deve
+scaricare un gran numero di pacchetti, non è bene farglieli installare
+subito, in caso dovesse andare male qualcosa. Dopo aver usato <tt>-d</>,
+gli archivi scaricati possono essere installati semplicemente dando di
+nuovo lo stesso comando senza l'opzione <tt>-d</>.
+
+</chapt>
+ <!-- }}} -->
+<!-- DSelect {{{ -->
+<!-- ===================================================================== -->
+<chapt>DSelect
+<p>
+Il metodo APT di <prgn>dselect</> fornisce tutte le funzionalità di APT
+all'interno dell'interfaccia grafica di selezione dei pacchetti
+<prgn>dselect</>. <prgn>dselect</> viene usato per selezionare i pacchetti
+da installare o rimuovere, ed APT li installa.
+
+<p>
+Per abilitare il metodo APT dovete selezionare [A]ccess in <prgn>dselect</>
+e scegliere il metodo APT; vi verrà chiesto un insieme di fonti
+(<em>Sources</>), cioè di posti da cui scaricare gli archivi.
+Tali fonti possono essere siti Internet remoti, mirror locali di Debian
+o CDROM; ciascuna di esse può fornire una parte dell'archivio Debian,
+ed APT le combinerà insieme in un set completo di pacchetti. Se avete un
+CDROM è una buona idea indicare quello per primo, e poi i mirror, in modo
+da avere accesso alle ultime versioni; APT userà in questo modo automaticamente
+i pacchetti sul CDROM prima di scaricarli da Internet.
+
+<p>
+<example>
+ Set up a list of distribution source locations
+
+ Please give the base URL of the debian distribution.
+ The access schemes I know about are: http file
+
+ For example:
+ file:/mnt/debian,
+ ftp://ftp.debian.org/debian,
+ http://ftp.de.debian.org/debian,
+
+
+ URL [http://llug.sep.bnl.gov/debian]:
+</example>
+
+<p>
+La configurazione delle fonti inizia chiedendo la base dell'archivio Debian,
+propone come default un mirror HTTP, e poi chiede la distribuzione
+da scaricare.
+
+<p>
+<example>
+ Please give the distribution tag to get or a path to the
+ package file ending in a /. The distribution
+ tags are typically something like: stable unstable frozen non-US
+
+ Distribution [stable]:
+</example>
+
+<p>
+La distribuzione (``distribution'') fa riferimento alla versione Debian
+dell'archivio: <em>stable</> è l'ultima rilasciata, ed <em>unstable</>
+è quella di sviluppo. <em>non-US</> è disponibile solo su alcuni mirror,
+e contiene dei pacchetti in cui viene usata della tecnologia di criptazione
+o altre cose che non possano essere esportate dagli Stati Uniti; importare
+questi pacchetti negli US è però legale.
+
+<p>
+<example>
+ Please give the components to get
+ The components are typically something like: main contrib non-free
+
+ Components [main contrib non-free]:
+</example>
+
+<p>
+L'elenco dei componenti (``components'') si riferisce alla lista di
+sotto-distribuzioni da scaricare. Ciascuna distribuzione viene divisa in
+base al copyright del software: la main contiene pacchetti la cui licenza
+soddisfa le DFSG, mentre contrib e non-free contengono software che ha
+diverse restrizioni sull'uso e sulla distribuzione.
+
+<p>
+Si possono inserire un qualsiasi numero di fonti, e lo script di
+configurazione continuerà a chiedere fino a che abbiate specificato tutti gli
+elementi che volete.
+
+<p>
+Prima di cominciare ad usare <prgn>dselect</> è necessario aggiornare
+l'elenco dei pacchetti disponibili selezionando [U]pdate dal menù:
+si tratta di un sovrainsieme di ciò che fa <tt>apt-get update</>,
+che rende l'informazione scaricata disponibile a
+<prgn>dselect</>. [U]pdate deve essere fatto anche se prima è stato dato
+<tt>apt-get update</>.
+
+<p>
+Si può a questo punto continuare selezionando i pacchetti desiderati
+usando [S]elect e poi installando con [I]nstall. Se si usa il metodo APT,
+i comandi [C]onfig e [R]emove non hanno significato, dato che entrambe le
+fasi sono contenute in [I]nstall.
+
+<p>
+Per default APT rimuoverà automaticamente i pacchetti che sono stati installati
+con successo. Per modificare questo comportamento, si inserisca
+<tt>Dselect::clean "prompt";</> in /etc/apt/apt.conf.
+
+</chapt>
+ <!-- }}} -->
+<!-- The Interfaces {{{ -->
+<!-- ===================================================================== -->
+<chapt>L'interfaccia
+
+<p>
+Entrambi i metodi, <prgn>dselect</> APT ed <prgn>apt-get</>, condividono la
+stessa interfaccia; si tratta di un sistema semplice che indica in genere
+cosa sta per fare, e poi lo fa.
+<footnote>
+Il metodo <prgn>dselect</> è in realtà un insieme di script di wrapper ad
+<prgn>apt-get</>. Il metodo fornisce delle funzionalità maggiori del
+solo <prgn>apt-get</>.
+</footnote>
+Dopo la stampa di un riassunto delle operazioni che saranno fatte,
+APT stampa dei messaggi informativi sullo stato del sistema, in modo che
+possiate avere davanti agli occhi a quale punto dell'operazione si trova,
+e quanto ancora si deve aspettare.
+
+<!-- ===================================================================== -->
+<sect>Avvio
+
+<p>
+Prima di ciascuna operazione, eccetto l'aggiornamento della lista, APT
+compie alcune operazioni per prepararsi, oltre a dei controlli dello
+stato del sistema. In qualsiasi momento le stesse operazioni possono essere
+fatte con <tt>apt-get check</>
+<p>
+<example>
+# apt-get check
+Reading Package Lists... Done
+Building Dependancy Tree... Done
+</example>
+
+<p>
+La prima cosa che fa è leggere tutti i file dei pacchetti in memoria,
+usando uno schema di caching in modo da rendere la stessa operazione più
+veloce la seconda volta che la si fa. Se alcuni dei file dei pacchetti
+non vengono trovati, sono ignorati e viene stampato un avvertimento
+all'uscita di apt-get.
+
+<p>
+L'operazione finale consiste in un'analisi dettagliata delle
+dipendenze del sistema: viene controllato che tutte le dipendenze dei
+singoli pacchetti installati o non scompattati siano soddisfatte.
+Se vengono individuati dei problemi, viene stampato un resoconto,
+ed <prgn>apt-get</> esce senza eseguire alcuna operazione.
+
+<p>
+<example>
+# apt-get check
+Reading Package Lists... Done
+Building Dependancy Tree... Done
+You might want to run apt-get -f install' to correct these.
+Sorry, but the following packages have unmet dependencies:
+ 9fonts: Depends: xlib6g but it is not installed
+ uucp: Depends: mailx but it is not installed
+ blast: Depends: xlib6g (>= 3.3-5) but it is not installed
+ adduser: Depends: perl-base but it is not installed
+ aumix: Depends: libgpmg1 but it is not installed
+ debiandoc-sgml: Depends: sgml-base but it is not installed
+ bash-builtins: Depends: bash (>= 2.01) but 2.0-3 is installed
+ cthugha: Depends: svgalibg1 but it is not installed
+ Depends: xlib6g (>= 3.3-5) but it is not installed
+ libreadlineg2: Conflicts:libreadline2 (<< 2.1-2.1)
+</example>
+
+<p>
+In questo esempio il sistema ha molti problemi, tra cui uno piuttosto serio
+con la libreadlineg2. Per ciascun pacchetto che ha dipendenze non soddisfatte,
+viene stampata una linea che indica il pacchetto che crea il problema e
+quali problemi ci sono. Viene inclusa inoltre una breve spiegazione
+del perché il pacchetto ha un problema di dipendenze.
+
+<p>
+Ci sono due modi in cui un sistema possa arrivare in uno stato problematico
+di questo genere: il primo è causato dal fatto che <prgn>dpkg</> possa
+mancare alcune relazioni sottili tra pacchetti durante un aggiornamento
+del sistema<footnote>APT considera comunque tutte le dipendenze note,
+e cerca di prevenire problemi ai pacchetti</footnote>; il secondo è possibile
+se l'installazione di un pacchetto fallisce, ed in questo caso è possibile
+che un pacchetto venga scompattato senza che tutti quelli da cui dipende
+siano stati installati.
+
+<p>
+La seconda possibilità è meno seria della prima, dato che APT gestisce
+l'ordine di installazione dei pacchetti; in entrambi i casi l'opzione
+<tt>-f</> di <prgn>apt-get</> gli farà trovare una soluzione e lo farà
+continuare. Il metodo APT di <prgn>dselect</> comprende sempre l'opzione
+<tt>-f</> per permettere di configurare facilmente anche i pacchetti con
+script errati.
+
+<p>
+Se viene usata però l'opzione <tt>-f</> per correggere un sistema in uno
+stato molto problematico, è possibile che anche con l'opzione il programma
+fallisca, subito o durante la sequenza di installazione. In entrambi i casi
+è necessario usare dpkg a mano (probabilmente usando delle opzioni
+di forzatura) per correggere quanto basta per poter fare continuare APT.
+</sect>
+
+<!-- ===================================================================== -->
+<sect>Il resoconto sullo stato
+
+<p>
+Prima di procedere, <prgn>apt-get</> presenterà un resoconto delle operazioni
+che sta per fare. In genere tale resoconto varierà con il tipo di operazioni
+da fare, ma ci sono alcuni elementi comuni: in tutti i casi gli elenchi
+dipendono dallo stato finale delle cose, e tengono conto dell'opzione
+<tt>-f</> e di altre attività rilevanti per il comando da eseguire.
+
+<sect1>L'elenco dei pacchetti Extra
+<p>
+<example>
+The following extra packages will be installed:
+ libdbd-mysql-perl xlib6 zlib1 xzx libreadline2 libdbd-msql-perl
+ mailpgp xdpkg fileutils pinepgp zlib1g xlib6g perl-base
+ bin86 libgdbm1 libgdbmg1 quake-lib gmp2 bcc xbuffy
+ squake pgp-i python-base debmake ldso perl libreadlineg2
+ ssh
+</example>
+
+<p>
+L'elenco dei pacchetti Extra mostra tutti i pacchetti che verranno installati
+o aggiornati oltre a quelli indicati sulla linea di comando. Viene generato
+solo per il comando <tt>install</>. I pacchetti elencati sono spesso il
+risultato di un'operazione di auto installazione (Auto Install).
+</sect1>
+
+<sect1>I pacchetti da rimuovere
+<p>
+<example>
+The following packages will be REMOVED:
+ xlib6-dev xpat2 tk40-dev xkeycaps xbattle xonix
+ xdaliclock tk40 tk41 xforms0.86 ghostview xloadimage xcolorsel
+ xadmin xboard perl-debug tkined xtetris libreadline2-dev perl-suid
+ nas xpilot xfig
+</example>
+
+<p>
+L'elenco dei pacchetti da rimuovere (Remove) indica tutti i pacchetti che
+verranno rimossi dal sistema. Può essere mostrato per una qualsiasi delle
+operazioni, e deve sempre essere esaminato attentamente per assicurarsi
+che non venga eliminato qualcosa di importante. Con l'opzione <tt>-f</>
+è particolarmente probabile che vengano eliminati dei pacchetti, ed in questo
+caso va fatta estrema attenzione. La lista può contenere dei pacchetti
+che verranno rimossi perché sono già rimossi parzialmente, forse a causa
+di un'installazione non terminata correttamente.
+</sect1>
+
+<sect1>L'elenco dei nuovi pacchetti installati
+<p>
+<example>
+The following NEW packages will installed:
+ zlib1g xlib6g perl-base libgdbmg1 quake-lib gmp2 pgp-i python-base
+</example>
+
+<p>
+L'elenco dei nuovi pacchetti installati (New) è semplicemente un appunto
+su quello che accadrà. I pacchetti nell'elenco non sono al momento installati
+nel sistema, ma lo saranno alla fine delle operazioni di APT.
+</sect1>
+
+<sect1>L'elenco dei pacchetti trattenuti
+<p>
+<example>
+The following packages have been kept back
+ compface man-db tetex-base msql libpaper svgalib1
+ gs snmp arena lynx xpat2 groff xscreensaver
+</example>
+
+<p>
+In ogni caso in cui il sistema viene aggiornato nel suo insieme, c'è la
+possibilità che non possano venire installate nuove versioni di alcuni
+pacchetti, dato che potrebbero richiedere l'installazione di pacchetti non
+presenti nel sistema, o entrare in conflitto con altri già presenti.
+In questo caso, il pacchetto viene elencato nella lista di quelli
+trattenuti (Kept Back). Il miglior modo per convincere i pacchetti
+elencati in questa lista è di installarli con <tt>apt-get install</> o
+usare <prgn>dselect</> per risolvere i problemi.
+</sect1>
+
+<sect1>Messaggi di attenzione sui pacchetti trattenuti
+<p>
+<example>
+The following held packages will be changed:
+ cvs
+</example>
+
+<p>
+A volte si può richiedere ad APT di installare un pacchetto
+che è stato trattenuto; in questi casi viene stampato un messaggio di
+attenzione, che avverte che il pacchetto verrà modificato. Questo
+dovrebbe accadere solo durante operazioni di dist-upgrade o di install.
+</sect1>
+
+<sect1>Resoconto finale
+<p>
+Infine, APT stamperà un riassunto di tutte le modifiche che accadranno.
+
+<p>
+<example>
+206 packages upgraded, 8 newly installed, 23 to remove and 51 not upgraded.
+12 packages not fully installed or removed.
+Need to get 65.7M/66.7M of archives. After unpacking 26.5M will be used.
+</example>
+
+<p>
+La prima linea del riassunto è semplicemente una versione ridotta di tutte
+le liste, ed include il numero di aggiornamenti -- cioè dei pacchetti
+già installati per cui sono disponibili nuove versioni. La seconda
+linea indica il numero di pacchetti con problemi di configurazione,
+probabilmente in conseguenza di un'installazione non andata a buon fine.
+La linea finale indica i requisiti di spazio dell'installazione: i primi
+due numeri indicano rispettivamente il numero di byte che devono
+essere trasferiti da posizioni remote, ed il secondo la dimensione totale
+di tutti gli archivi necessari per l'installazione. Il numero successivo
+indica la differenza in dimensione tra i pacchetti già installati
+e quelli che lo saranno, ed è approssimativamente equivalente allo spazio
+richiesto in /usr dopo l'installazione. Se si stanno rimuovendo dei
+pacchetti, il valore può indicare lo spazio che verrà liberato.
+
+<p>
+Si possono generare altri resoconti usando l'opzione -u per mostrare
+i pacchetti da aggiornare, ma sono simili all'esempio precedente.
+</sect>
+
+<!-- ===================================================================== -->
+<sect>La visualizzazione dello stato
+<p>
+Durante il download degli archivi e dei file dei pacchetti, APT
+stampa una serie di messaggi di stato.
+
+<p>
+<example>
+# apt-get update
+Get:1 http://ftp.de.debian.org/debian-non-US/ stable/non-US/ Packages
+Get:2 http://llug.sep.bnl.gov/debian/ frozen/contrib Packages
+Hit http://llug.sep.bnl.gov/debian/ frozen/main Packages
+Get:4 http://ftp.de.debian.org/debian-non-US/ unstable/binary-i386/ Packages
+Get:5 http://llug.sep.bnl.gov/debian/ frozen/non-free Packages
+11% [5 frozen/non-free `Waiting for file' 0/32.1k 0%] 2203b/s 1m52s
+</example>
+
+<p>
+Le linee che cominciano con <em>Get</> vengono stampate quando APT inizia
+a scaricare un file, e l'ultima linea indica il progresso dell'operazione.
+Il primo valore in percentuale indica la percentuale totale di tutti i file;
+dato che la dimensione dei file Package non è nota, purtroppo a volte
+<tt>apt-get update</> fa una stima poco accurata.
+
+<p>
+La sezione successiva della linea di stato viene ripetuta una volta per
+ciascuna fase del download, ed indica l'operazione in corso, insieme
+ad alcune informazioni utili su cosa stia accadendo. A volte questa
+sezione contiene solamente <em>Forking</>, che significa che il sistema
+operativo sta caricando il modulo. La prima parola dopo la parentesi quadra
+aperta è il nome breve dell'oggetto che si sta scaricando, che per gli archivi
+è il nome del pacchetto.
+
+<p>
+All'interno delle virgolette c'è una stringa informativa, che indica il
+progresso della fase di negoziazione del download. Tipicamente comincia con
+<em>Connecting</>, procede con <em>Waiting for file</> e poi con
+<em>Downloading</> o <em>Resuming</>. Il valore finale è il numero di byte
+che sono stati scaricati dal sito remoto: una volta cominciato il
+download viene rappresentato come <tt>102/10.2k</>, che indica che
+sono stati scaricati 102 byte di 10.2 kilobyte. La dimensione totale
+viene sempre espressa in notazione a quattro cifre, per risparmiare
+spazio. Dopo la dimensione viene indicato un indicatore
+progressivo della percentuale del file. Il penultimo elemento è la velocità
+istantanea media, che viene aggiornata ogni 5 secondi, e riflette la
+velocità di trasferimento dei dati in quel periodo. Infine, viene
+visualizzato il tempo stimato per il trasferimento, che viene aggiornato
+periodicamente e riflette il tempo necessario per completare tutte le
+operazioni alla velocità di trasferimento mostrata.
+
+<p>
+La visualizzazione dello stato viene aggiornata ogni mezzo secondo per
+fornire un feedback costante del processo di download, e le linee Get
+scorrono indietro quando viene cominciato il download di un nuovo file.
+Dato che la visualizzazione dello stato viene costantemente
+aggiornata, non è adatta per essere registrata in un file; per non
+visualizzarla si può usare l'opzione <tt>-q</>.

+
+<p>
+APT usa <prgn>dpkg</> per installare gli archivi e passerà all'interfaccia
+<prgn>dpkg</> una volta finito il download.
+<prgn>dpkg</> porrà anche alcune domande durante la manipolazione dei

--- /dev/null
+libapt-pkg v2 to v3 incorperates several source-incompatible changes that
+people need to be aware of.. Many of this changes are done so that most old
+source will continue to function, but perhaps at reduced functionality.
+
+* pkgDepCache is no longer self initilizing, you have to call the Init
+ method seperately after constructing it. Users of pkgCacheFile do not
+ need to worry about this
+* GetCandidateVer/etc is gone from the pkgCache. It exists only in the
+ DepCache and is just an inline around the new Policy class
+* TargetVer/TargetDist have been eliminated. Nothing should have been using
+ these.
+* There is a policy class. The v0 policy engine which has been used since
+ APT 0.0.0 is instantiated by the DepCache by default. However pkgCacheFile
+ constructs and initializes the new v4 engine. People accessing GetCandidate
+ version outside of a CacheFile/DepCache will need to instantiate and
+ initialize a policy engine on their own.
+* All byte counters are now doubles to advoid 4G wraparound. The compiler
+ should generate warnings on any incorrect use of these.
+* The PriorityType/CompType/DepType functions have been moved out of the
+ iterators and into generate static functions of pkgCache - inline stubs
+ are left in the iterators.
+* The deb dependency element parser has been made into a static function
+ of the list parser and enhanced to optionally understand architecture
+ restrictions.
+* TagSections no longer include the trailing \n. This means that the
+ Offset/Length of a package record in the version structure also does not
+ include the trailing \n.
+* GenCaches::SelectFile accepts a site parameter now too.
+* Global version compare functions are gone. If you
+ #define APT_COMPATABILITY 1
+ They will come back as they were before. Code should be updated to
+ reference the compare functions to the VersioningSystem (VS) referenced
+ by the Cache or _system structures.
+* Initialization is now two stage (define APT_COMPATABILITY..) The first
+ stage, pkgInitConfig is called before commandline parsing, and
+ pkgInitSystem is called after. This gives the user the oppertunity to
+ override default settings from the config files before startup has been
+ finalized.
+* pkgSourceList has been gutted. All the junk that was in there before is
+ cleaned up and put in the pkgIndexFile class. There is very little API
+ corrispondence here..
+* pkgMakeStatusCacheMem is gone, pkgMakeStatusCache does the same thing if
+ you set the AllowMem flag. Also, you can get a copy of the map used to
+ store the cache to advoid having to remap it in the calling code. A bunch
+ of other cache related functions are gone, but nobody should have been using
+ them in the first place!
+* Downloading the 'Package' and 'Source' index files is different, use
+ the GetIndexes call in SourceList.
+* SourceRecords::Parser::Source is gone, replaced with Index which does
+ much the same thing.
+* DynamicMap has changed slightly, nobody should care
+* pkgMakeOnlyStatusCache exists, which creates a really small cache that
+ only contains the status file, and in memory.
+* The pkgRecords stuff is changed to abstract through the index file list
+ (should be transparent largely)
+* Locking is handled differently, there is no dpkg lock class, the _system
+ class provides Lock/UnLock methods
+* pkgDepCache is not a subclass of pkgCache, it agregates it now. Some
+ compatibility functions are provided that make this transition fairly
+ easy.
+* The following functions have had minor argument changes:
+ - pkgSimulate(pkgDepCache &Cache);
+ + pkgSimulate(pkgDepCache *Cache);
+
+ - pkgProblemResolver(pkgDepCache &Cache);
+ + pkgProblemResolver(pkgDepCache *Cache);
+
+ - pkgDepCache(MMap &Map,Policy *Plcy = 0);
+ + pkgDepCache(pkgCache *Cache,Policy *Plcy = 0);
+
+ - pkgOrderList(pkgDepCache &Cache);
+ + pkgOrderList(pkgDepCache *Cache);
+
+ - pkgPackageManager(pkgDepCache &Cache);
+ + pkgPackageManager(pkgDepCache *Cache);
+
+ - pkgCache(MMap &Map,bool DoMap = true);
+ + pkgCache(MMap *Map,bool DoMap = true);
+
+ - pkgCacheGenerator(DynamicMMap &Map,OpProgress &Progress);
+ + pkgCacheGenerator(DynamicMMap *Map,OpProgress *Progress);
+
+ - pkgTagFile(FileFd &F,unsigned long Size = 32*1024);
+ + pkgTagFile(FileFd *F,unsigned long Size = 32*1024);
+
+* Configuration class is const-correct
+* The legacy ability to create a PkgFileIterator that started at Begin
+ is gone, everyone should be using FileBegin().
+* A new dependency relation called obsoletes that is similar to conflicts.

This document describes how to use APT in a non-networked environment,
archive but can easily fit a subset large enough for most users. The idea
is to use APT to generate a list of packages that are required and then fetch
them onto the disc using another machine with good connectivity. It is
-even Possible to use another Debian machine with APT or to use a completely

+On the remote Debian machine the first thing to do is mount the disc and copy
<em>/var/lib/dpkg/status</em> to it. You will also need to create the directories
outlined in the Overview, <em>archives/partial/</em> and <em>lists/partial/</em>
Then take the disc to the remote machine and configure the sources.list.
</example>
The dist-upgrade command can be replaced with any-other standard APT commands,
-you can even use an APT front end such as <em>gnome-apt</em> [still in
-development].
+particularly dselect-upgrad. You can even use an APT front end such as
+<em>dselect</em> However this presents a problem in communicating your
+selections back to the local computer.
<p>
Now the disc contains all of the index files and archives needed to upgrade
It is necessary for proper function to re-specify the status file to be the
local one. This is very important!
+<p>
+If you are using dselect you can do the very risky operation of copying
+disc/status to /var/lib/dpkg/status so that any selections you made on the
+remote machine are updated. I highly recommend that people only make selections
+on the local machine - but this may not always be possible. DO NOT copy

The /disc/wget-script file will now contain a list of wget commands to execute

+ <para>
+ The package resource list is used to locate archives of the package
+ distribution system in use on the system. At this time, this manual page
+ documents only the packaging system used by the Debian GNU/Linux system.
+ This control file is located in <filename>/etc/apt/sources.list</>
+ <para>
+ The source list is designed to support any number of active sources and a
+ variety of source media. The file lists one source per line, with the
+ most preferred source listed first. The format of each line is:
+ <literal/type uri args/. The first item, <literal/type/, determines the
+ format for <literal/args/. <literal/uri/ is a Universal Resource Identifier
+ (URI), which is a superset of the more specific and well-known Universal
+ Resource Locator, or URL. The rest of the line can be marked as a comment
+ by using a #.
+ </RefSect1>
+
+ <RefSect1><Title>The deb and deb-src types</>
+ <para>
+ The <literal/deb/ type describes a typical two-level Debian archive,
+ <filename>distribution/component</>. Typically, <literal/distribution/ is
+ generally one of <literal/stable/, <literal/unstable/, or
+ <literal/frozen/, while component is one of <literal/main/,
+ <literal/contrib/, <literal/non-free/, or <literal/non-us/. The
+ <literal/deb-src/ type describes a debian distribution's source code in
+ the same form as the <literal/deb/ type. A <literal/deb-src/ line is
+ required to fetch source indexes.
+ <para>
+ The format for a <filename/sources.list/ entry using the <literal/deb/
+ and <literal/deb-src/ types are:
+ <literallayout>deb uri distribution [component1] [componenent2] [...]</literallayout>
+ <para>
+ The URI for the <literal/deb/ type must specify the base of the Debian
+ distribution, from which APT will find the information it needs.
+ <literal/distribution/ can specify an exact path, in which case the
+ components must be omitted and <literal/distribution/ must end with a
+ slash (/). This is useful for when only a particular sub-section of the
+ archive denoted by the URI is of interest. If <literal/distribution/ does
+ not specify an exact path, at least one <literal/component/ must be present.
+ <para>
+ <literal/distribution/ may also contain a variable, <literal/$(ARCH)/,
+ which expands to the Debian architecture (i386, m68k, powerpc, ...)
+ used on the system. This permits archiecture-independent
+ <filename/sources.list/ files to be used. In general this is only of
+ interest when specifying an exact path, <literal/APT/ will automatically
+ generate a URI with the current architecture otherwise.
+ <para>
+ Since only one distribution can be specified per line it may be necessary
+ to have multiple lines for the same URI, if a subset of all available
+ distributions or components at that location is desired.
+ APT will sort the URI list after it has generated a complete set
+ internally, and will collapse multiple references to the same Internet
+ host, for instance, into a single connection, so that it does not
+ inefficiently establish an FTP connection, close it, do something else,
+ and then re-establish a connection to that same host. This feature is
+ useful for accessing busy FTP sites with limits on the number of
+ simultaneous anonymous users. bf(APT) also parallizes connections to
+ different hosts to more effectively deal with sites with low bandwidth.
+ <para>
+ It is important to list sources in order of preference, with the most
+ preferred source listed first. Typically this will result in sorting
+ by speed from fastest to slowest (CD-ROM followed by hosts on a local
+ network, followed by distant Internet hosts, for example).
+ <para>
+ Some examples:
+ <literallayout>
+deb http://http.us.debian.org/debian stable main contrib non-free

+ <para>
+ The currently recognized URI types are cdrom, file, http, and ftp.
+ <VariableList>
+ <VarListEntry><term>file</term>
+ <ListItem><Para>
+ The file scheme allows an arbitrary directory in the file system to be

+ archives.
+ </VarListEntry>
+
+ <VarListEntry><term>cdrom</term>
+ <ListItem><Para>
+ The cdrom scheme allows APT to use a local CDROM drive with media
+ swapping. Use the &apt-cdrom; program to create cdrom entries in the
+ source list.
+ </VarListEntry>
+
+ <VarListEntry><term>http</term>
+ <ListItem><Para>
+ The http scheme specifies an HTTP server for the archive. If an environment
+ variable <EnVar/http_proxy/ is set with the format
+ http://server:port/, the proxy server specified in
+ <EnVar/http_proxy/ will be used. Users of authenticated HTTP/1.1 proxies
+ may use a string of the format http://user:pass@server:port/
+ Note that this is an insecure method of authentication.
+ </VarListEntry>
+
+ <VarListEntry><term>ftp</term>
+ <ListItem><Para>
+ The ftp scheme specifies an FTP server for the archive. APT's FTP behavior
+ is highly configurable; for more information see the
+ &apt-conf; manual page. Please note that a ftp proxy can be specified
+ by using the <EnVar/ftp_proxy/ environment variable. It is possible to
+ specify a http proxy (http proxy servers often understand ftp urls) using

+
+ <VarListEntry><term>copy</term>
+ <ListItem><Para>
+ The copy scheme is identical to the file scheme except that packages are

+ </VarListEntry>
+
+ <VarListEntry><term>rsh</term><term>ssh</term>
+ <ListItem><Para>
+ The rsh/ssh method method invokes rsh/ssh to connect to a remote host
+ as a given user and access the files. No password authentication is
+ possible, prior arrangements with RSA keys or rhosts must have been made.

+Acronyms
+~~~~~~~~
+* dpkg is a 'word' the first d may be upper case - Dpkg
+* APT is a proper Acronym, all upper case please.
+
+Pkg - A Package
+Ver - A version
+
+Indenting, Comments, Etc
+~~~~~~~~~~~~~~~~~~~~~~~~
+Would make Linus cry :P However it is what I prefer. 3 space indent,
+8 space tab all braces on seperate lines, function return on the same line
+as the function, cases aligned with their code. The 'indent' options for
+this style are:
+ indent -bl -bli0 -di1 -i3 -nsc -ts8 -npcs -npsl
+
+Each file gets a block at the top that should describe what the file does,
+basically a summary of purpose along with any special notes and
+attributions. The }}} and {{{ are folding marks if you have a folding
+editor such as jed, the function seperators are intended to give
+a visual seperate between functions for easier browsing of the larger files,
+or indexed folding if you have such an editor.
+
+Each file should have 1 or 0 primary include files, that include
+file must always be the first include file included by the .cc. G++
+#pragma interface/implementation is used, as well as anti-include-twice
+#ifdefs.
+
+Include files, since there are so many, get their own subdirectory off
+the include search path, this is used consistently throughout all the code.
+#include "" should never be used for a global exported header file, only
+local ones.
+
+C++ Features
+~~~~~~~~~~~~
+Due to the legacy compiler heritage, exceptions, RTTI and name spaces are
+not used. Templates are used *sparingly* since G++ has traditionally had
+very weak support for them, this includes STL templates.
+
+Namespaces will probably be put in the code sometime after G++ 3, which will
+be a huge re-org again to make sanity, the majority of all nested things
+will go away.
+
+The C++ standard library's non parameterized types (string is included in
+this) are used freely when appropriate.
+
+The new C++ #include <iostream> (note the lack of a .h) is used for the
+standard library, but not for my code.
+
+Arguments and Ownership
+~~~~~~~~~~~~~~~~~~~~~~~
+[much of the code follows this now]
+These guidlines should be followed except in two cases.. the first
+is where it makes no sense, such as in a casting operator and the second is to
+retain API compatibility (this should be rare, since a change in the input
+almost always designates a change in ownership rules).
+
+ * Pass by value or pass by reference should borrow the object from the
+ caller
+ * Pass by non-const reference may be used to indicate a OUT type variable
+ * Pass by pointer (except in the case where the pointer is really an array)
+ should be used when the object will be retained or ownership will be
+ transfered. Ownership transference should be rare and noted by a comment.
+ * Standard C things (FILE * etc) should be left as is.
+
+ * Return by references should indicate a borrowed object
+ * Return by pointer (except arrays) should indicate ownership is
+ transfered. Return by pointer should not be used unless ownership is
+ transfered.
+ * Return by pointer to variable indicates ownership transfer unless the
+ pointer is an 'input' parameter (designated generally by an =0,
+ indicating a default of 'none')
+
+Non-ownership transfering arrays/lists should probably return an iterator
+typedef or references..

+
+ contents - Archive contents generator
+
+ The GenContents class is a back end for an archive contents generator.
+ It takes a list of per-deb file name and merges it into a memory
+ database of all previous output. This database is stored as a set
+ of binary trees linked across directories to form a tree of all files+dirs
+ given to it. The tree will also be sorted as it is built up thus
+ removing the massive sort time overhead.
+
+ By breaking all the pathnames into components and storing them
+ separately a space savings is realized by not duplicating the string
+ over and over again. Ultimately this saving is sacrificed to storage of
+ the tree structure itself but the tree structure yields a speed gain
+ in the sorting and processing. Ultimately it takes about 5 seconds to
+ do 141000 nodes and about 5 meg of ram.
+
+ The tree looks something like:
+
+ usr/
+ / \ / libslang
+ bin/ lib/ --> libc6
+ / \ \ libfoo
+ games/ sbin/
+
+ The ---> is the DirDown link
