Add support for CONFLICTS

[zi0r]

It would be neat to see the conflicts for ports and be able to follow links to ports that match the expression.

You would want to support parsing:

CONFLICTS, CONFLICTS_INSTALL and CONFLICTS_BUILD

[zi0r]

Example port

I really like this idea. My first reading is that CONFLICTS contains the PKG_NAME value, which is already stored in the database. Should be very straight forward to do this.

I think it's a great idea.

Plot twist: CONFLICTS variables can contain wildcards and regexy-type things.

Example:
[0-9]*

From https://svnweb.freebsd.org/ports/head/Mk/bsd.port.mk?view=markup#l436

# CONFLICTS             - A list of package name patterns that the port conflicts
#                                 with, separated by blanks.  The names may include shell
#                                 pattern meta-characters "*", "?", "[", "]", and "!".
#                                 Example: apache*-1.2* apache*-1.3.[012345] apache-*+ssl_*
#
# CONFLICTS_BUILD
#                               - Check conflict prior to the build.
#
# CONFLICTS_INSTALL
#                               - Check conflict prior to the installation stage.

Your task: find out if the field contains a regex or not. Using php.

These three new columns with each contain their respective values obtained directly from the Makefile via:

make -V CONFLICTS -V CONFLICTS_BUILD -V CONFLICTS_INSTALL

For example:

# make -V CONFLICTS -V CONFLICTS_BUILD -V CONFLICTS_INSTALL -f Makefile PORTSDIR=/var/db/repos/PORTS-head                       
bacula5-server-*

Column creation:

$ psql freshports.dev
psql (10.5)
Type "help" for help.

freshports.dev=# begin;
BEGIN
freshports.dev=# ALTER TABLE ports ADD COLUMN conflicts TEXT;
ALTER TABLE
freshports.dev=# ALTER TABLE ports ADD COLUMN conflicts_build TEXT;
ALTER TABLE
freshports.dev=# ALTER TABLE ports ADD COLUMN conflicts_install TEXT;
ALTER TABLE
freshports.dev=# commit;
COMMIT
freshports.dev=#

I see conflicts listed at https://www.freshports.org/sysutils/bacula9-server/

See also #103

Done. Example: https://dev.freshports.org/sysutils/bacula13-server/#conflicts and I added a tag for it.

I also added in a new tag: https://dev.freshports.org/sysutils/bacula13-server/#pkg-plist
