REPREPRO

NAME

reprepro − produce, manage and sync a local repository of debian packages reprepro − produce, manage and sync a local repository of Debian packages

SYNOPSIS

reprepro −−help

reprepro [ options ] command [ per−command−arguments ]

DESCRIPTION

reprepro is a tool to manage a repository of Debian packages (.deb, .udeb, .dsc, ...). It stores files either being injected manually or downloaded from some other repository (partially) mirrored into a pool/ hierarchy. Managed packages and checksums of files are stored in a libdb4.3 database (or libdb4.4 or libdb3, depending what reprepro was compiled with), so no database server is needed. Checking signatures of mirrored repositories and creating signatures of the generated Package indices is supported.

WARNING: Some functions are still quite experimental and not very heavily tested. Be careful.

Former working title of this program was mirrorer.

GLOBAL OPTIONS

Options can be specified before the command. Each affects a different subset of commands and is ignored by other commands.
−h −−help

Displays a short list of options and commands with description.

−v, −V, −−verbose

Be more verbose. Can be applied multiple times. One uppercase −V counts as five lowercase −v.

−−silent

Be less verbose. Can be applied multiple times. One −v and one −s cancel each other out.

−f, −−force

This option is ignored, as it no longer exists.

−b, −−basedir basedir

Sets the base−dir all other default directories are relative to. If none is supplied and the REPREPRO_BASE_DIR environment variable is not set either, the current directory will be used.

−−outdir outdir

Sets the base−dir of the repository to manage, i.e. where the pool/ subdirectory resides. And in which the dists/ directory is placed by default. The default for this is basedir.

−−confdir confdir

Sets the directory where the configuration is searched in.

If none is given, basedir/conf will be used.

−−distdir distdir

Sets the directory to generate index files relatively to. (i.e. things like Packages.gz, Sources.gz and Release.gpg)

If none is given, outdir/dists is used.

Note: apt has dists hard-coded in it, so this is mostly only useful for testing or when your webserver pretends another directory structure than your physical layout.

Warning: Beware when changing this forth and back between two values not ending in the same directory. Reprepro only looks if files it wants are there. If nothing of the content changed and there is a file it will not touch it, assuming it is the one it wrote last time, assuming any different −−distdir ended in the same directory. So either clean a directory before setting −−distdir to it or do an export with the new one first to have a consistent state.

−−logdir logdir

The directory where files generated by the Log: directive are stored if they have no absolute path.

If none is given, basedir/logs is used.

−−dbdir dbdir

Sets the directory where reprepro keeps its databases.

If none is given, basedir/db is used.

Note: This is permanent data, no cache. One has almost to regenerate the whole repository when this is lost.

−−listdir listdir

Sets the directory where downloads it downloads indices to when importing from other repositories. This is temporary data and can be safely deleted when not in an update run.

If none is given, basedir/lists is used.

−−overridedir overridedir (OBSOLETE)

Sets the directory where specified override−files will be searched in if they do not start with a slash. If none is given, basedir/override is used.
This will be removed in a future version. Since reprepro 3.0.0, also the directory given to −−confdir is searched for override files.

−−methoddir methoddir

Look in methoddir instead of /usr/lib/apt/methods for methods to call when importing from other repositories.

−C, −−component component

Limit the specified command to this component only. This will force added packages to this component, limit removing packages from this component, only list packages in this component, and/or otherwise only look at packages in this component, depending on the command in question.

−A, −−architecture architecture

Limit the specified command to this architecture only. (i.e. only list such packages, only remove packages from the specified architecture, or otherwise only look at/act on this architecture depending on the specific command).

Note that architecture all packages can be included to each architecture but are then handled separately. Thus using −A correctly allows to have different versions of an architecture all package in different architectures of the same distribution.

−T, −−type dsc|deb|udeb

Limit the specified command to this packagetype only. (i.e. only list such packages, only remove such packages, only include such packages, ...)

−S, −−section section

Overrides the section of inclusions. (Also override possible override files)

−P, −−priority priority

Overrides the priority of inclusions. (Also override possible override files)

−−export=(never|changed|lookedat|force)

This option specify whether and how the high level actions (e.g. install, update, pull, delete) should export the index files of the distributions they work with.

−−export=normal (default till 3.0.0)

−−export=lookedat (alternative new name since 3.0.1) In this mode every distribution the action handled will be exported, unless there was an error possibly corrupting it.
Note
that only missing files and files whose intended content changed between before and after the action will be written. To get a guaranteed current export, use the export action.

−−export=changed (default since 3.0.1)

In this mode every distribution actually changed will be exported, unless there was an error possibly corrupting it. (i.e. if nothing changed, not even missing files will be created.)
Note
that only missing files and files whose intended content changed between before and after the action will be written. To get a guaranteed current export, use the export action.

−−export=force

Always export all distributions looked at, even if there was some error possibly bringing it into a inconsistent state.

−−export=never

No index files are exported. You will have to call export later.
Note
that you most likely additionally need the −−keepunreferenced option, if you do want some of the files pointed to by the untouched index files to vanish.

−−ignore=what

Ignore errors of type what. See the section ERROR IGNORING for possible values.

−−nolistsdownload

When running update or checkupdate do not download any Release or index files (and also do not check them). This is hardly useful except when you just run one of those command for the same distributions.

−−keepunreferencedfiles

Do not delete files that are no longer used because the package they are from is deleted/replaced with a newer version from the last distribution it was in.

−−keepunneededlists

Do not try to delete files from lists/ before updating, that seem to belong to one of the updated distributions but will not be needed. Those file may happen to exist when you removed some Update: rule or changed Components/Architectures/... . This is mostly only useful if you want to temporarily disable some update rule and want to avoid downloading their index files again when you read it later.

−−keepdirectories

Do not try to rmdir parent directories after files or directories have been removed from them. (Do this if your directories have special permissions you want keep, do not want to be pestered with warnings about errors to remove them, or have a buggy rmdir call deleting non-empty directories.)

−−ask−passphrase

Ask for passphrases when signing things and one is needed. This is a quick and dirty implementation using the obsolete getpass(3) function with the description gpgme is supplying. So the prompt will look quite funny and support for passphrases with more than 8 characters depend on your libc. I suggest using gpg−agent or something like that instead.

−−noskipold

When updating do not skip targets where no new index files and no files marked as already processed are available.

If you changed a script to preprocess downloaded index files or changed a Listfilter, you most likely want to call reprepro with −−noskipold.

−−waitforlock count

If there is a lockfile indicating another instance of reprepro is currently using the database, retry count times after waiting for 10 seconds each time. The default is 0 and means to error out instantly.

−−spacecheck full|none

The default is full:
In the update commands, check for every to be downloaded file which filesystem it is on and how much space is left.
To disable this behaviour, use none.

−−dbsafetymargin bytes-count

If checking for free space, reserve byte-count bytes on the filesystem containing the db/ directory. The default is 104857600 (i.e. 100MB), which is quite large. But as there is no way to know in advance how large the databases will grow and libdb is extremely touchy in that regard, lower only when you know what you do.

−−safetymargin bytes-count

If checking for free space, reserve byte-count bytes on filesystems not containing the db/ directory. The default is 1048576 (i.e. 1MB).

−−noguessgpgtty

Don’t set the environment variable GPG_TTY, even when it is not set, stdin is terminal and /proc/self/fd/0 is a readable symbolic link.

−−nooldfilesdb

Do not create a files.db file, but only newer checksums.db file. This will make it impossible for reprepro versions before 3.3.0 to access this repository. Versions before 3.0 will not recognize that and destroy it. Thus it is still switched off by default, even though it gives an space and speed improvement.

COMMANDS

export [ codenames ]

Generate all index files for the specified distributions. (For all if none is specified). This will normally be done automatically and more fine−tuned when including or removing packages, so seldom needed; but is nevertheless a good way to see if a new distributions config−file does the expected things.

[ −−delete ] createsymlinks [ codenames ]

Creates suite symbolic links in the dists/-directory pointing to the corresponding codename.

It will not create links, when multiple of the given codenames would be linked from the same suite name, or if the link already exists (though when −−delete is given it will delete already existing symlinks)

list codename packagename

List all packages (source and binary, except when −T or −A is given) with the given name in all components (except when −C is given) and architectures (except when −A is given) of the specified distribution.

listfilter codename condition

as list, but does not list a single package, but all packages matching the given condition.

The format of the formulas is those of the dependency lines in Debian packages’ control files with some extras. That means a formula consists of names of fields with a possible condition for its content in parentheses. These atoms can be combined with an exclamation mark ’!’ (meaning not), a pipe symbol ’|’ (meaning or) and a coma ’,’ (meaning and). Additionally parentheses can be used to change binding (otherwise ’!’ binds more than ’|’ than ’,’).

The values given in the search expression are directly alphabetically compared to the headers in the respective index file. That means that each part Fieldname (cmp value) of the formula will be true for exactly those package that have in the Package or Sources file a line starting with fieldname and a value is alphabetically cmp to value.

Examples:

reprepro −b . listfilter test2 ’Section (== admin)’ will list all packages in distribution test2 with a Section field and the value of that field being admin.

reprepro −b . −T deb listfilter test2 ’Source (== blub) | ( !Source , Package (== blub) )’ will find all .deb Packages with either a Source field blub or no Source field and a Package field blub. (That means all package generated by a source package blub, except those also specifying a version number with its Source).

remove codename package-names

Delete all packages in the specified distribution, that have package name listed as argument. (i.e. remove all packages list with the same arguments and options would list, except that an empty package list is not allowed.)

removefilter codename condition

Delete all packages listfilter with the same arguments would list.

removesrc codename source-name [version]

Remove all packages in distribution codename belonging to source package source-name. (Limited to those with source version version if specified).

If package tracking is activated, it will use that information to find the packages, otherwise it traverses all package indices for the distribution.

update [ codenames ]

Sync the specified distributions (all if none given) as specified in the config with their upstreams. See the description of conf/updates below.

iteratedupdate [ codenames ] (EXPERIMENTAL!)

This is an experimental variant of update, that processes the distributions and targets within them one by one, resulting in much lower memory consumption for an update of multiple distributions.

checkupdate [ codenames ]

Same like update, but will show what it will change instead of actually changing it.

predelete [ codenames ]

This will determine which packages a update would delete or replace and remove those packages. This can be useful for reducing space needed while upgrading, but there will be some time where packages are vanished from the lists so clients will mark them as obsolete. Plus if you cannot download a updated package in the (hopefully) following update run, you will end up with no package at all instead of an old one. This will also blow up .diff files if you are using the tiffany example or something similar. So be careful when using this option or better get some more space so that update works.

pull [ codenames ]

pull in newer packages into the specified distributions (all if none given) from other distributions in the same repository. See the description of conf/pulls below.

checkpull [ codenames ]

Same like pull, but will show what it will change instead of actually changing it.

includedeb codename .deb-filename

Include the given binary Debian package (.deb) in the specified distribution, applying override information and guessing all values not given and guessable.

includeudeb codename .deb-filename

Same like includedeb, but for .udeb files.

includedsc codename .dsc-filename

Include the given Debian source package (.dsc, including other files like .orig.tar.gz, .tar.gz and/or .diff.gz) in the specified distribution, applying override information and guessing all values not given and guessable.

Note that .dsc files do not contain section or priority, but the Sources.gz file needs them. reprepro tries to parse .diff and .tar files for it, but is only able to resolve easy cases. If reprepro fails to extract those automatically, you have to either specify a DscOverride or give them via −S and −P

include codename .changes-filename

Include in the specified distribution all packages found and suitable in the .changes file, applying override information guessing all values not given and guessable.

processincoming rulesetname [.changes-file]

Scan an incoming directory and process the .changes files found there. If a filename is supplied, processing is limited to that file. rulesetname identifies which rule-set in conf/incoming determines which incoming directory to use and in what distributions to allow packages into. See the section about this file for more information.

check [ codenames ]

Check if all packages in the specified distributions have all files needed properly registered.

checkpool [ fast ]

Check if all files believed to be in the pool are actually still there and have the known md5sum. When fast is specified md5sum is not checked.

collectnewchecksums

Calculate all supported checksums for all files in the pool. (Versions prior to 3.3 did only store md5sums, 3.3 added sha1).

rereference

Forget which files are needed and recollect this information.

dumpreferences

Print out which files are marked to be needed by whom.

dumpunreferenced

Print a list of all filed believed to be in the pool, that are not known to be needed.

deleteunreferenced

Remove all known files (and forget them) in the pool not marked to be needed by anything.

reoverride [ codenames ]

Reapply the override files to the given distributions (Or only parts thereof given by −Af,−C or −T).

Note: only the control information is changed. Changing a section to a value, that would cause another component to be guessed, will not cause any warning.

dumptracks [ codenames ]

Print out all information about tracked source packages in the given distributions.

retrack [ codenames ]

Recreate a tracking database for the specified distributions. This contains ouf of three steps. First all files marked as part of a source package are set to unused. Then all files actually used are marked as thus. Finally tidytracks is called remove everything no longer needed with the new information about used files.

(This behaviour, though a bit longsome, keeps even files only kept because of tracking mode keep and files not otherwise used but kept due to includechanges or its relatives. Before version 3.0.0 such files were lost by running retrack).

removealltracks [ codenames ]

Removes all source package tracking information for the given distributions.

removetrack codename sourcename version

Remove the trackingdata of the given version of a given sourcepackage from a given distribution. This also removes the references for all used files.

tidytracks [ codenames ]

Check all source package tracking information for the given distributions for files no longer to keep.

copy destination-codename source-codename packages...

Copy the given packages from one distribution to another. The packages are copied verbatim, no override files are consulted. Only components and architectures present in the source distribution are copied.

copysrc destination-codename source-codename source-package [versions]

look at each package (where package means, as usual, every package be it dsc, deb or udeb) in the distribution specified by source-codename and identifies the relevant source package for each. All packages matching the specified source-package name (and any version if specified) are copied to the destination-codename distribution. The packages are copied verbatim, no override files are consulted. Only components and architectures present in the source distribution are copied.

copyfilter destination-codename source-codename formula

Copy packages matching the given formula (see listfilter). (all versions if no version is specified). The packages are copied verbatim, no override files are consulted. Only components and architectures present in the source distribution are copied.

restore codename snapshot packages...
restoresrc
codename snapshot source-epackage [versions]
restorefilter
destination-codename snapshot formula

Like the copy commands, but do not copy from another distribution, but from a snapshot generated with gensnapshot. Note that this blindly trusts the contents of the files in your dists/ directory and does no checking.

clearvanished

Remove all package databases that no longer appear in conf/distributions. If −−delete is specified, it will not stop if there are still packages left. Even without −−delete it will unreference files still marked as needed by this target. (Use −−keepunreferenced to not delete them if that was the last reference.)

Do not forget to remove all exported package indices manually.

gensnapshot codename directoryname

Generate a snapshot of the distribution specified by codename in the directory conf/codename/snapshots/directoryname/ and reference all needed files in the pool as needed by that. No Content files are generated and no export hooks are run.

Note that there is currently no automated way to remove that snapshot again (not even clearvanished will unlock the referenced files after the distribution itself vanished). You will have to remove the directory yourself and tell reprepro to _removereferences s=codename=directoryname before deleteunreferenced will delete the files from the pool locked by this.

To access such a snapshot with apt, add something like the following to your sources.list file:
deb method://as/without/snapshot
codename/snapshots/name main

rerunnotifiers [ codenames ]

Run all external scripts specified in the Log: options of the specified distributions.

translatefilelists

Translate the file list cache within db/contents.cache.db into the new format used since reprepro 3.0.0.

Make sure you have at least half of the space of the current db/contents.cache.db file size available in that partition.

internal commands
These are hopefully never needed, but allow manual intervention. WARNING: Is is quite easy to get into an inconsistent and/or unfixable state.
_detect
[ filekeys ]

Look for the files, which filekey is given as argument or as a line of the input (when run without arguments), and calculate their md5sum and add them to the list of known files. (Warning: this is a low level operation, no input validation or normalization is done.)

_forget [ filekeys ]

Like _detect but remove the given filekey from the list of known files. (Warning: this is a low level operation, no input validation or normalization is done.)

_listmd5sums

Print a list of all known files and their md5sums.

_listchecksums

Print a list of all known files and their recorded checksums.

_addmd5sums

alias for the newer

_addchecksums

Add information of known files (without any check done) in the strict format of _listchecksums output (i.e. don’t dare to use a single space anywhere more than needed).

_dumpcontents identifier

Printout all the stored information of the specified part of the repository. (Or in other words, the content the corresponding Packages or Sources file would get)

_addreference filekey identifier

Manually mark filekey to be needed by identifier

_removereferences identifier

Remove all references what is needed by identifier.

__extractcontrol .deb-filename

Look what reprepro believes to be the content of the control file of the specified .deb-file.

__extractfilelist .deb-filename

Look what reprepro believes to be the list of files of the specified .deb-file.

_fakeemptyfilelist filekey

Insert an empty filelist for filekey. This is a evil hack around broken .deb files that cannot be read by reprepro.

_addpackage codenam filename packages...

Add packages from the specified filename to part specified by -C -A and -T of the specified distribution. Very strange things can happen if you use it improperly.

CONFIG FILES

reprepo uses three config files, which are searched in the directory specified with −−confdir or in the conf/ subdirectory of the basedir.

If a file options exists, it is parsed line by line. Each line can be the long name of a command line option (without the −−) plus an argument, where possible. Those are handled as if they were command line options given before (and thus lower priority than) any other command line option. (and also lower priority than any environment variable).

To allow command line options to override options file options, most boolean options also have a corresponding form starting with −−no.

(The only exception is when the path to look for config files changes, the options file will only opened once and of course before any options within the options file are parsed.)

The file distributions is always needed and describes what distributions to manage, while updates is only needed when syncing with external repositories and pulls is only needed when syncing with repositories in the same reprepro database.

The last three are in the format control files in Debian are in, i.e. paragraphs separated by empty lines consisting of fields. Each field consists of a fieldname, followed by a colon, possible whitespace and the data. A field ends with a newline not followed by a space or tab.

Lines starting with # as first character are ignored, while in other lines the # character and everything after it till the newline character are ignored.

conf/distributions
Codename

This required field is the unique identifier of a distribution and used as directory name within dists/ It is also copied into the Release files.

Suite

This optional field is simply copied into the Release files. In Debian it contains names like stable, testing or unstable. To create symlinks from the Suite to the Codename, use the createsymlinks command of reprepro.

FakeComponentPrefix

If this field is present, its argument is added before every Component written to the main Release file, and removed from the end of the Codename and Suite fields in that file.
So
Codename: bla/updates
Suite: foo/updates
FakeComponentPrefix: updates
Components: main bad

will create a Release file with
Codename: bla
Suite: foo
Components: updates/main updates/bad

in it, but otherwise nothing is changed. This makes the distribution look more like Debian’s security archive, thus work around problems with apt’s workarounds for that.

AlsoAcceptFor

A list of distribution names. When a .changes file is told to be included into this distribution with the include command and the distribution header of that file is neither the codename, nor the suite name, nor any name from the list, a wrongdistribution error is generated. The process_incoming command will also use this field, see the description of Allow and Default from the conf/incoming file for more information.

Version

This optional field is simply copied into the Release files.

Origin

This optional field is simply copied into the Release files.

Label

This optional field is simply copied into the Release files.

NotAutomatic

This optional field is simply copied into the Release files. (The value is handled as arbitrary string, though anything but yes does make much sense right now.)

Description

This optional field is simply copied into the Release files.

Architectures

This required field lists the binary architectures within this distribution and if it contains source (i.e. if there is an item source in this line this Distribution has source. All other items specify things to be put after "binary−" to form directory names and be checked against "Architecture:" fields.)

This will also be copied into the Release files. (With exception of the source item, which will not occur in the topmost Release file whether it is present here or not)

Components

This required field lists the component of a distribution. See GUESSING for rules which component packages are included into by default. This will also be copied into the Release files.

UDebComponents

Components with a debian−installer subhierarchy containing .udebs. (E.g. simply "main")

Update

When this field is present, it describes which update rules are used for this distribution. There also can be a magic rule minus ("−"), see below.

Pull

When this field is present, it describes which pull rules are used for this distribution. Pull rules are like Update rules, but get their stuff from other distributions and not from external sources. See the description for conf/pulls.

SignWith

When this field is present, a Release.gpg file will be generated. If the value is "yes" or "default", the default key is used. Otherwise the value will be given to libgpgme to determine to key to use. (That should be roughly the one gpg −−list−secret−keys value would output). This key should either have no passphrase, you need to specify −−ask−passphrase or use gpg−agent.

DebOverride

When this field is present, it describes the override file used when including .deb files.

UDebOverride

When this field is present, it describes the override file used when including .udeb files.

DscOverride

When this field is present, it describes the override file used when including .dsc files.

DebIndices, UDebIndices, DscIndices

Choose what kind of Index files to export. The first part describes what the Index file shall be called. The second argument determines the name of a Release file to generate or not to generate if missing. Then at least one of ".", ".gz" or ".bz2" specifying whether to generate uncompressed output, gzipped output, bzip2ed output or any combination. (bzip2 is only available when compiled with bzip2 support, so it might not be available when you compiled it on your own). If an argument not starting with dot follows, it will be executed after all index files are generated. (See the examples for what argument this gets). The default is:
DebIndices: Packages Release . .gz
UDebIndices: Packages . .gz
DscIndices: Sources Release .gz

Contents

Enable the creation of Contents files listing all the files within the binary packages of a distribution. (Which is quite slow, you have been warned).

In earlier versions, the first argument was a rate at which to extract file lists. As this did not work and was no longer easily possible after some factorisation, this is no longer supported.

The arguments of this field is a space separated list of options. If there is a udebs keyword, .udebs are also listed (in a file called uContents−architecture.) If there is a nodebs keyword, .debs are not listed. (Only useful together with udebs) If there is at least one of the keywords ., .gz and/or .bz2, the Contents files are written uncompressed, gzipped and/or bzip2ed instead of only gzipped.

ContentsArchitectures

Limit generation of Contents files to the architectures given. If this field is not there, all architectures are processed. An empty field means no architectures are processed, thus not very useful.

ContentsComponents

Limit what components are processed for the Contents-arch files to the components given. If this field is not there, all components are processed. An empty field is equivalent to specify nodebs in the Contents field, while a non-empty field overrides a nodebs there.

ContentsUComponents

Limit what components are processed for the uContents files to the components given. If this field is not there and there is the udebs keyword in the Contents field, all .udebs of all components are put in the uContents.arch files. If this field is not there and there is no udebs keyword in the Contents field, no uContents-arch files are generated at all. A non-empty fields implies generation of uContents-arch files (just like the udebs keyword in the Contents field), while an empty one causes no uContents-arch files to be generated.

Uploaders

Specified a file (relative to confdir if not starting with a slash) to specify who is allowed to upload packages. With this there are no limits, and this file can be ignored via −−ignore=uploaders. See the section UPLOADERS FILES below.

Tracking

Enable the (experimental) tracking of source packages. The argument list needs to contain exactly one of the following:
keep
Keeps all files of a given source package, until that is deleted explicitly via removetrack. This is currently the only possibility to keep older packages around when all indices contain newer files.
all
Keep all files belonging to a given source package until the last file of it is no longer used within that distribution.
minimal
Remove files no longer included in the tracked distribution. (Remove changes and includebyhand files once no file is in any part of the distribution).
And any number of the following (or none):
includechanges
Add the .changes file to the tracked files of a source package. Thus it is also put into the pool.
includebyhand
Not yet implemented.
embargoalls
Not yet implemented.
keepsources
Even when using minimal mode, do not remove source files until no file is needed any more.
needsources
Not yet implemented.

Log

Specify a file to log additions and removals of this distribution into and/or external scripts to call when something is added or removed. The rest of the Log: line is the filename, every following line (as usual, have to begin with a single space) the name of a script to call. The name of the script may be preceded with options of the form −−type=(dsc|deb|udeb), −−architecture=name or −−component=name to only call the script for some parts of the distribution. An script with argument −−changes is called when a .changes file was accepted by include or processincoming (and with other arguments).

For information how it is called and some examples take a look at manual.html in reprepro’s source or /usr/share/doc/reprepro/

If the filename for the log files does not start with a slash, it is relative to the directory specified with −−logdir, the scripts are relative to −−confdir unless starting with a slash.

conf/updates

Name

The name of this update−upstream as it can be used in the Update field in conf/distributions.

Method

An URI as one could also give it apt, e.g. http://ftp.debian.de/debian which is simply given to the corresponding apt−get method. (So either apt−get has to be installed, or you have to point with −−methoddir to a place where such methods are found.

Fallback

(Still experimental:) A fallback URI, where all files are tried that failed the first one. They are given to the same method as the previous URI (e.g. both http://), and the fallback-server must have everything at the same place. No recalculation is done, but single files are just retried from this location.

Config

This can contain any number of lines, each in the format apt−get −−option would expect. (Multiple lines - as always - marked with leading spaces).

For example: Config: Acquire::Http::Proxy=http://proxy.yours.org:8080

Suite

The suite to update from. If this is not present, the codename of the distribution using this one is used. Also "*/whatever" is replaced by "<codename>/whatever"

Components

The components to update. Each item can be either the name of a component or a pair of a upstream component and a local component separated with ">". (e.g. "main>all contrib>all non−free>notall")

If this field is not there, all components from the distribution to update are tried.

An empty field means no source or .deb packages are updated by this rule, but only .udeb packages, if there are any.

A rule might list components not available in all distributions using this rule. In this case unknown components are silently ignored. (Unless you start reprepro with the −−fast option, it will warn about components unusable in all distributions using that rule. As exceptions, unusable components called none are never warned about, for compatibility with versions prior to 3.0.0 where and empty field had a different meaning.)

Architectures

The architectures to update. If omitted all from the distribution to update from. (As with components, you can use ">" to download from one architecture and add into another one. (This only determine in which Package list they land, it neither overwrites the Architecture line in its description, nor the one in the filename determined from this one. In other words, it is no really useful without additional filtering))

UDebComponents

Like Components but for the udebs.

VerifyRelease

Download the Release.gpg file and check if it is a signature of the Releasefile with the key given here. (In the Format as "gpg −−with−colons −−list−key" prints it, i.e. the last 16 hex digits of the fingerprint) Multiple keys can be specified by separating them with a "|" sign. Then finding a signature from one of the will suffice.

IgnoreRelease

If this is present, no Release file will be downloaded and thus the md5sums of the other index files will not be checked.

FilterFormula

This can be a formula to specify which packages to accept from this source. The format is misusing the parser intended for Dependency lines. To get only architecture all packages use "architecture (== all)", to get only at least important packages use "priority (==required) | priority (==important)".

FilterList

This takes at least two arguments: The first one is the default action when something is not found, the then a list of filenames (relative to −−confdir, if not starting with a slash), in the format of dpkg −−get−selections and only packages listed in there as install will be installed. Things listed as deinstall or purge or nonexistent will be treated like not being known. A package being hold will not be upgraded but also not downgraded or removed. To abort the whole upgrade/pull if a package is available, use error.

ListHook

If this is given, it is executed for all downloaded index files with the downloaded list as first and a filename that will be used instead of this. (e.g. "ListHook: /bin/cp" works but does nothing.)

conf/pulls
This file contains the rules for pulling packages from one distribution to another. While this can also be done with update rules using the file or copy method and using the exported indices of that other distribution, this way is faster. It also ensures the current files are used and no copies are made. (This also leads to the limitation that pulling from one component to another is not possible.)

Each rule consists out of the following fields:

Name

The name of this pull rule as it can be used in the Pull field in conf/distributions.

From

The codename of the distribution to pull packages from.

Components

The components of the distribution to get from.

If this field is not there, all components from the distribution to update are tried.

A rule might list components not available in all distributions using this rule. In this case unknown components are silently ignored. (Unless you start reprepro with the −−fast option, it will warn about components unusable in all distributions using that rule. As exception, unusable components called none are never warned about, for compatibility with versions prior to 3.0.0 where and empty field had a different meaning.)

Architectures

The architectures to update. If omitted all from the distribution to pull from. As in conf/updates, you can use ">" to download from one architecture and add into another one. (And again, only useful with filtering to avoid packages not architecture all to migrate).

UDebComponents

Like Components but for the udebs.

FilterFormula
FilterList

The same as with update rules.

OVERRIDE FILES

Override files are yet only used when things are manually added, not when imported while updating from an external source. The format should resemble the extended ftp−archive format, to be specific it is:

packagename field name new value

For example:
kernel−image−2.4.31−yourorga Section protected/base
kernel−image−2.4.31−yourorga Priority standard
kernel−image−2.4.31−yourorga Maintainer That’s me <me@localhost>
reprepro Priority required

All fields of a given package will be replaced by the new value specified in the override file. While the field name is compared case-insensitive, it is copied in exactly the form in the override file there. (Thus I suggest to keep to the exact case it is normally found in index files in case some other tool confuses them.) More than copied is the Section header (unless −S is supplied), which is also used to guess the component (unless −C is there). There is no protection against changing headers like Package, Filename, Size or MD5sum, though changing these functional fields may give the most curious results. (Most likely reprepro may error out in future invocations).

conf/incoming
Every chunk is a rule set for the process_incoming command. Possible fields are:

Name

The name of the rule-set, used as argument to the scan command to specify to use this rule.

IncomingDir

The Name of the directory to scan for .changes files.

TempDir

A directory where the files listed in the processed .changes files are copied into before they are read. You can avoid some copy operatations by placing this directory within the same moint point the pool hierachy is (at least partially) in.

Allow arguments

Each argument is either a pair name1>name2 or simply name which is short for name>name. Each name2 must identify a distribution, either by being Codename, a unique Suite, or a unique AlsoAcceptFor from conf/distributions. Each upload has each item in its Distribution: header compared first to last with each name1 in the rules and is put in the first one accepting this package. e.g.:
Allow: local unstable>sid
or
Allow: stable>security-updates stable>proposed-updates

Default distribution

Every upload not put into any other distribution because of an Allow argument is put into distribution if that accepts it.

Multiple

Allow putting an upload in multiple distributions if it lists more than one. (Without this field, procession stops after the first success).

Permit options

A list of options to allow things otherwise causing errors:
unused_files

Do not stop with error if there are files listed in the .changes file if it lists files not belonging to any package in it.
older_version

Ignore a package not added because there already is a strictly newer version available instead of treating this as an error.

Cleanup options

A list of options to cause more files in the incoming directory to be deleted:
unused_files

If there is unused_files in Permit then also delete those files when the package is deleted after successful processing.
on_deny

If a .changes file is denied processing because of missing signatures or allowed distributions to be put in, delete it and all the files it references.
on_error

If a .changes file causes errors while processing, delete it.

UPLOADERS FILES

These files specified by the Uploaders header in the distribution definition as explained above describe what key a .changes file as to be signed with to be included in that distribution.

Empty lines and lines starting with a hash are ignored, every other line has to be of one of this three forms:
allow * by unsigned

which allows everything without a valid signature in,
allow * by any key

which allows everything with any valid signature in or
allow * by key
key-id
which allows everything signed by this key-id (to be specified without any spaces) in.

(Other statements will follow once somebody tells me what restrictions are useful).

ERROR IGNORING

With −−ignore on the command line or an ignore line in the options file, the following type of errors can be ignored:
brokenold
(hopefully never seen)

If there are errors parsing an installed version of package, do not error out, but assume it is older than anything else, has not files or no source name.

brokensignatures

If a .changes or .dsc file contains at least one invalid signature and no valid signature (not even expired or from an expired or revoked key), reprepro assumes the file got corrupted and refuses to use it unless this ignore directive is given.

brokenversioncmp (hopefully never seen)

If comparing old and new version fails, assume the new one is newer.

dscinbinnmu

If a .changes file has an explicit Source version that is different the to the version header of the file, than reprepro assumes it is binary non maintainer upload (NMU). In that case, source files are not permitted in .changes files processed by include or processincoming. Adding −−ignore=dscinbinnmu allows it for the include command.

emptyfilenamepart (insecure)

Allow strings to be empty that are used to construct filenames. (like versions, architectures, ...)

extension

Allow to includedeb files that do not end with .deb, to includedsc files not ending in .dsc and to include files not ending in .changes.

forbiddenchar (insecure)

Do not insist on Debian policy for package and source names and versions. Thus allowing all 7-bit characters but slashes (as they would break the file storage) and things syntactically active (spaces, underscores in filenames in .changes files, opening parentheses in source names of binary packages). To allow some 8-bit chars additionally, use 8bit additionally.

8bit (more insecure)

Allow 8-bit characters not looking like overlong UTF-8 sequences in filenames and things used as parts of filenames. Though it hopefully rejects overlong UTF-8 sequences, there might be other characters your filesystem confuses with special characters, thus creating filenames possibly equivalent to /mirror/pool/main/../../../etc/shadow (Which should be safe, as you do not run reprepro as root, do you?) or simply overwriting your conf/distributions file adding some commands in there. So do not use this if you are paranoid, unless you are paranoid enough to have checked the code of your libs, kernel and filesystems.

ignore (for forward compatibility)

Ignore unknown ignore types given to −−ignore.

malformedchunk (I hope you know what you do)

Do not stop when finding a line not starting with a space but no colon(:) in it. These are otherwise rejected as they have no defined meaning.

missingfield (safe to ignore)

Ignore missing fields in a .changes file that are only checked but not processed. Those include: Format, Date, Urgency, Maintainer, Description, Changes

missingfile (might be insecure)

When including a .dsc file from a .changes file, try to get files needed but not listed in the .changes file (e.g. when someone forgot to specify −sa to dpkg−buildpackage) from the directory the .changes file is in instead of erroring out. (−−delete will not work with those files, though.)

spaceonlyline (I hope you know what you do)

Allow lines containing only (but non-zero) spaces. As these do not separate chunks as thus will cause reprepro to behave unexpected, they cause error messages by default.

surprisingarch

Do not reject a .changes file containing files for a architecture not listed in the Architecture-header within it.

surprisingbinary

Do not reject a .changes file containing .deb files containing packages whose name is not listed in the "Binary:" header of that changes file.

undefinedtarget (hope you are not using the wrong db directory)

Do not stop when the packages.db file contains databases for codename/packagetype/component/architectures combinations that are not listed in your distributions file.

This allows you to temporarily remove some distribution from the config files, without having to remove the packages in it with the clearvanished command. You might even temporarily remove single architectures or components, though that might cause inconsistencies in some situations.

undefinedtracking (hope you are not using the wrong db directory)

Do not stop when the tracking file contains databases for distributions that are not listed in your distributions file.

This allows you to temporarily remove some distribution from the config files, without having to remove the packages in it with the clearvanished command. You might even temporarily disable tracking in some distribution, but that is likely to cause inconsistencies in there, if you do not know, what you are doing.

unknownfield (for forward compatibility)

Ignore unknown fields in the config files, instead of refusing to run then.

unusedarch (safe to ignore)

No longer reject a .changes file containing no files for any of the architectures listed in the Architecture-header within it.

unusedoption

Do not complain about command line options not used by the specified action (like −−architecture).

uploaders

The include command will accept packages that would otherwise been rejected by the uploaders file.

wrongdistribution (safe to ignore)

Do not error out if a .changes file is to be placed in a distribution not listed in that files’ Distributions: header.

wrongsourceversion

Do not reject a .changes file containing .deb files with a different opinion on what the version of the source package is.
(Note: reprepro only compares literally here, not by meaning.)

wrongversion

Do not reject a .changes file containing .dsc files with a different version.
(Note: reprepro only compares literally here, not by meaning.)

GUESSING

When including a binary or source package without explicitly declaring a component with −C it will take the first component with the name of the section, being prefix to the section, being suffix to the section or having the section as prefix or any. (In this order)

Thus having specified the components: "main non−free contrib non−US/main non−US/non−free non−US/contrib" should map e.g. "non−US" to "non−US/main" and "contrib/editors" to "contrib", while having only "main non−free and contrib" as components should map "non−US/contrib" to "contrib" and "non−US" to "main".

NOTE: Always specify main as the first component, if you want things to end up there.

NOTE: unlike in dak, non−US and non−us are different things...

NOMENCLATURE

Codename the primary identifier of a given distribution. This are normally things like sarge, etch or sid.
basename

the name of a file without any directory information.

filekey

the position relative to the mirrordir. (as found as "Filename:" in Packages.gz)

full filename

the position relative to /

architecture

The term like sparc, i386, mips, ... . To refer to the source packages, source is sometimes also treated as architecture.

component

Things like main, non−free and contrib (by policy and some other programs also called section, reprepro follows the naming scheme of apt here.)

section

Things like base, interpreters, oldlibs and non−free/math (by policy and some other programs also called subsections).

md5sum

The checksum of a file in the format "<md5sum of file> <length of file>"

Some note on updates

A version is not overwritten with the same version.
reprepro
will never update a package with a version it already has. This would be equivalent to rebuilding the whole database with every single upgrade. To force the new same version in, remove it and then update. (If files of the packages changed without changing their name, make sure the file is no longer remembered by reprepro. Without −−keepunreferencedfiled and without errors while deleting it should already be forgotten, otherwise a deleteunreferenced or even some __forget might help.)

The magic delete rule ("−").
A minus as a single word in the Update: line of a distribution marks everything to be deleted. The mark causes later rules to get packages even if they have (strict) lower versions. The mark will get removed if a later rule sets the package on hold (hold is not yet implemented, in case you might wonder) or would get a package with the same version (Which it will not, see above). If the mark is still there at the end of the processing, the package will get removed.

Thus the line "Update: − rules " will cause all packages to be exactly the highest Version found in rules. The line "Update: nearrules " will do the same, except if it needs to download packages, it might download it from near except when too confused. (It will get too confused e.g. when near or rules have multiple versions of the package and the highest in near is not the first one in rules, as it never remember more than one possible spring for a package.

Warning: This rule applies to all type/component/architecture triplets of a distribution, not only those some other update rule applies to. (That means it will delete everything in those!)

ENVIRONMENT VARIABLES

Environment variables are always overwritten by command line options, but overwrite options set in the options file. (Even when the options file is obviously parsed after the environment variables as the environment may determine the place of the options file).
REPREPRO_BASE_DIR

The directory in this variable is used instead of the current directory, if no −b or −−basedir options are supplied.
It is also set in all hook scripts called by reprepro (relative to the current directory or absolute, depending on how reprepro got it).

REPREPRO_CONFIG_DIR

The directory in this variable is used when no −−confdir is supplied.
It is also set in all hook scripts called by reprepro (relative to the current directory or absolute, depending on how reprepro got it).

REPREPRO_OUT_DIR

This is not used, but only set in hook scripts called by reprepro to the directory in which the pool subdirectory resides (relative to the current directory or absolute, depending on how reprepro got it).

REPREPRO_DIST_DIR

This is not used, but only set in hook scripts called by reprepro to the dists directory (relative to the current directory or absolute, depending on how reprepro got it).

GNUPGHOME

Not used by reprepro directly. But reprepro uses libgpgme, which calls gpg for signing and verification of signatures. And your gpg will most likely use the content of this variable instead of "~/.gnupg". Take a look at gpg(1) to be sure.

GPG_TTY

When there is a gpg-agent running that does not have the passphrase cached yet, gpg will most likely try to start some pinentry program to get it. If that is pinentry-curses, that is likely to fail without this variable, because it cannot find a terminal to ask on. In this cases you might set this variable to something like the value of $(tty) or $SSH_TTY or anything else denoting a usable terminal. (You might also want to make sure you actually have a terminal available. With ssh you might need the −t option to get a terminal even when telling gpg to start a specific command).

By default, reprepro will set this variable to what the symbolic link /proc/self/fd/0 points to, if stdin is a terminal, unless you told with −−noguessgpgtty to not do so.

BUGS

Increased verbosity always shows those things one does not want to know. (Though this might be inevitable and a corollary to Murphy)

Reprepro uses berkley db, which was a big mistake. The most annoying problem not yet worked around is database corruption when the disk runs out of space. (Luckily if it happens while downloading packages while updating, only the files database is affected, which is easy (though time consuming) to rebuild, see recovery file in the documentation). Ideally put the database on another partition to avoid that.

While the source part is mostly considered as the architecture source some parts may still not use this notation.

WORK-AROUNDS TO COMMON PROBLEMS

gpgme returned an impossible condition

With the woody version this normally meant that there was no .gnupg directory in $HOME, but it created one and reprepro succeeds when called again with the same command. Since sarge the problem sometimes shows up, too. But it is no longer reproducible and it does not fix itself, neither. Try running gpg −−verify file-you-had-problems-with manually as the user reprepro is running and with the same $HOME. This alone might fix the problem. It should not print any messages except perhaps
gpg: no valid OpenPGP data found.
gpg: the signature could not be verified.
if it was an unsigned file.

not including .orig.tar.gz when a .changes file’s version does not end
in −0 or −1

If dpkg−buildpackage is run without the −sa option to build a version with a Debian revision not being −0 or −1, it does not list the .orig.tar.gz file in the .changes file. If you want to include such a file with reprepro when the .orig.tar.gz file does not already exist in the pool, reprepro will report an error. This can be worked around by:
call dpkg−buildpackage with −sa (recommended)
copy the .orig.tar.gz file to the proper place in the pool before
call reprepro with −−ignore=missingfile (discouraged)

leftover files in the pool directory.

reprepro is sometimes a bit too timid of deleting stuff. When things go wrong and there have been errors it sometimes just leaves everything where it is. To see what files reprepro remembers to be in your pool directory but does not know anything needing them right know, you can use
reprepro dumpunreferenced

To delete them:
reprepro deleteunreferenced

INTERRUPTING

Interrupting reprepro has its problems. Some things (like speaking with apt methods, database stuff) can cause problems when interrupted at the wrong time. Then there are design problems of the code making it hard to distinguish if the current state is dangerous or non-dangerous to interrupt. Thus if reprepro receives a signal normally sent to tell a process to terminate itself softly, it continues its operation, but does not start any new operations. (I.e. it will not tell the apt-methods any new file to download, it will not replace a package in a target, unless it already had started with it, it will not delete any files gotten dereferenced, and so on).

It only catches the first signal of each type. The second signal of a given type will terminate reprepro. You will risk database corruption and have to remove the lockfile manually.

Also note that even normal interruption leads to code-paths mostly untested and thus expose a multitude of bugs including those leading to data corruption. Better think a second more before issuing a command than risking the need for interruption.
