libsolv-constantids - fixed Ids for often used strings
Description
-----------
Constant Ids are Ids of strings that are often needed. They are defined
to ease programming and reduce the number of pool_str2id calls. The
constant Ids are part of the binary ABI of libsolv, a minor version
update will only add new constants and not change existing Ids to
maintain compatibility. The on-disk solv format does not use the fixed
Ids, but instead references the strings, so solv files can still be
read when the ABI is broken.
Special Strings
---------------
*ID_EMPTY ""*::
The empty string. It will always have Id 1.
*SYSTEM_SYSTEM "system:system"*::
The name of the always installed "system" solvable.

of the values stored in the attribute with the keyname.

Dependency Ids
--------------
Namespaces are special modifiers that change the meaning of a dependency.
Namespace dependencies are created with the REL_NAMESPACE flag. To make
custom namespaces work you have to implement a namespace callback function.
The dependency markers partition the dependency array in two parts with
different semantics.
*NAMESPACE_MODALIAS "namespace:modalias"*::
The dependency is a special modalias dependency that matches installed
hardware.
*NAMESPACE_SPLITPROVIDES "namespace:splitprovides"*::
The dependency is a special splitprovides dependency used to implement
updates that include a package split. A splitprovides dependency contains
a filename and a package name, it is matched if a package with the
provided package name is installed that contains the filename.
This namespace is implemented in libsolv, so you do not need a callback.
*NAMESPACE_LANGUAGE "namespace:language"*::
The dependency describes a language. The callback should return true
if the language was selected by the user.
*NAMESPACE_FILESYSTEM "namespace:filesystem"*::
The dependency describes a filesystem. The callback should return true
if the filesystem is needed.
*NAMESPACE_OTHERPROVIDERS "namespace:otherproviders"*::
This is a hack to allow self-conflicting packages. It is not needed
with current rpm version, so do not use this namespace.
*SOLVABLE_PREREQMARKER "solvable:prereqmarker"*::
This marker partitions the normal require dependencies from the
prerequires. It is not needed for dependency solving, but it is
used by the transaction ordering algorithm when a dependency cycle
needs to be broken (non-prereq deps get broken first).
*SOLVABLE_FILEMARKER "solvable:filemarker"*::
This marker partitions the package provides dependencies from the
synthetic file provides dependencies added by pool_addfileprovides().
Data Types
----------
Each attribute data is stored with a type, so that the lookup functions
know how to interpret the data. The following types are available:
*REPOKEY_TYPE_VOID "repokey:type:void"*::
No data is stored with this attribute. Thus you can only test if
the attribute exists or not. Useful to store boolean values.
*REPOKEY_TYPE_CONSTANT "repokey:type:constant"*::
The data is a constant 32bit number. The number is stored in the key
area, so using it does not cost extra storage space (but you need the
extra key space).
*REPOKEY_TYPE_CONSTANTID "repokey:type:constantid"*::
The data is a constant Id. The Id is stored in the key area,
so using it does not cost extra storage space (but you need the
extra key space).

Used to store file names.
*REPOKEY_TYPE_DIRNUMNUMARRAY "repokey:type:dirnumnumarray"*::
The data is a triple consisting of a directory Id and two 32bit
unsigned integers. Used to store disk usage information.
*REPOKEY_TYPE_MD5 "repokey:type:md5"*::
The data is a binary md5sum.
*REPOKEY_TYPE_SHA1 "repokey:type:sha1"*::
