This makes it easy to create a bunch of records that are all related to
each other in a single ovs-vsctl invocation. It adds an example to the
ovs-vsctl manpage.
Some of the uses for the formerly supported regular expression constraints
were simply to limit values to those in a set of allowed values.
This commit adds support for that kind of simple enumeration constraint.
The upcoming "remove" command for ovs-vsctl wants to try parsing an
argument two different ways. This doesn't work if a parse error always
aborts immediately. This commit fixes the problem, by making a parsing
failure pass up an error for higher layers to deal with instead of aborting
immediately.
This commit should have no user-visible effect.
These functions provide an alternative to JSON parsing and formatting that
is more human-friendly (and shorter).
These will be used in an upcoming commit to enhance ovs-vsctl.
This commit refactors the functions for working with "struct ovsdb_datum",
adding and exposing some more operations for ovs-vsctl to use in an
upcoming commit.
When a new record is inserted into a database, ovsdb logs the values of all
of the fields in the record. However, often new records have many columns
that contain default values. There is no need to log those values, so this
commit causes them to be omitted.
As a side effect, this also makes "ovsdb-tool show-log --more --more"
output easier to read, because record insertions print less noise. (Adding
--more --more to this command makes it print changes to database records.
The --more option will be introduced in an upcoming commit.)
