NAME¶
CPAN::SQLite::State - get state information on the database
DESCRIPTION¶
This module gets information on the current state of the database and compares
it to that obtained from the CPAN index files from
CPAN::SQLite::Info
and from the repositories from
CPAN::SQLite::PPM. For each of the four
tables
dists,
mods,
auths, and
ppms, two methods
are used to get this information:
- •
- "ids"
This method gets the ids of the relevant names, and versions, if applicable,
in the table.
- •
- "state"
This method compares the information in the tables obtained from the
"ids" method to that from the CPAN indices and ppm repositories.
One of three actions is then decided, which is subsequently acted upon in
CPAN::SQLite::Populate.
- •
- "insert"
If the information in the indices is not in the database, this information
is marked for insertion.
- •
- "update"
If the information in the database is older than that form the indices
(generally, this means an older version), the information is marked for
updating.
- •
- "delete"
If the information in the database is no longer present in the indices, the
information is marked for deletion.
