# DPorts and pkgng Dports is DragonFly's own third-party software build system. It is based on FreeBSD's Ports Collection. Differences between ports and DPorts are intentionally kept to a minimum, both to maintain familiarity for mutual users of both operating systems and also to leverage the tremendous amount of work the FreeBSD contributors put into ports. DPorts can and does feature ports unique to DragonFly, so it's truly a native system. The __pkgng__ tool called "pkg" is a modern and fast binary package manager. It was developed for FreeBSD, but PC-BSD used it in production first, followed soon after by DragonFly. In the future, it will be the only binary package manager on FreeBSD, just it is the only port manager in DPorts. __pkgng__ is not a replacement for port management tools like `ports-mgmt/portmaster` or `ports-mgmt/portupgrade`. While `ports-mgmt/portmaster` and `ports-mgmt/portupgrade` can install third-party software from both binary packages and DPorts, __pkgng__ installs only binary packages. On the other hand, many people use __pkgng__ by itself and never install the optional portupgrade or portmaster tools. ## Getting started with pkgng DragonFly daily snapshots and Releases (starting with 3.4) come with __pkgng__ already installed. Upgrades from earlier releases, however, will not have it. If the "pkg" program is missing on the system for any reason, it can be quickly bootstrapped without having to build it from source or even having dports installed: # make pkg-bootstrap # rehash # pkg-static install -y pkg # rehash If pkgsrc has ever been installed on the system, make sure all binaries produced by it have been removed: # rm -rf /usr/pkg Currently it's necessary to manually install the configuration file, but this requirement should disappear in the future. After installing the configuration file, you may want to open it up and edit it to select a different mirror. ## Configuring pkgng Older versions of pkgng saved their configuration at /usr/local/etc/pkg.conf; this file made reference to a PACKAGESITE. pkgng will still work based on this file, but will output errors: # pkg update pkg: PACKAGESITE in pkg.conf is deprecated. Please create a repository configuration file Updating repository catalogue pkg: Warning: use of http:// URL scheme with SRV records is deprecated: switch to pkg+http:// If you do __not__ see these errors, then skip to "Now, navigate to `/usr/local/etc/pkg/repos/`", otherwise: Listen to the errors: hash out the packagesite line, save the file, and move on. This can be done with vi: # vi /usr/local/etc/pkg.conf There will be two lines in the file like this: # Default Dports package server (California) PACKAGESITE: http://mirror-master.dragonflybsd.org/dports/${ABI}/LATEST Hash out the offending line: # Default Dports package server (California) # PACKAGESITE: http://mirror-master.dragonflybsd.org/dports/${ABI}/LATEST Note that, as of time of writing, there are two working package repositories: # Default Dports package server (California) # PACKAGESITE: http://mirror-master.dragonflybsd.org/dports/${ABI}/LATEST # European mirrors [...] #PACKAGESITE: http://dfly.schlundtech.de/dports/${ABI}/LATEST Test their performance---we will be using the fastest one. This may, or may not, be the one closest to you (the California site for the New World, the German site for the Old World). # ping schlundtech.de PING schlundtech.de (85.236.36.90): 56 data bytes 64 bytes from 85.236.36.90: icmp_seq=0 ttl=49 time=101.433 ms 64 bytes from 85.236.36.90: icmp_seq=1 ttl=49 time=59.177 ms 64 bytes from 85.236.36.90: icmp_seq=2 ttl=49 time=79.550 ms 64 bytes from 85.236.36.90: icmp_seq=3 ttl=49 time=88.268 ms 64 bytes from 85.236.36.90: icmp_seq=4 ttl=49 time=120.060 ms [...] --- schlundtech.de ping statistics --- 20 packets transmitted, 19 packets received, 5.0% packet loss round-trip min/avg/max/stddev = 49.555/96.064/186.662/33.559 ms # ping mirror-master.dragonflybsd.org PING avalon.dragonflybsd.org (199.233.90.72): 56 data bytes 64 bytes from 199.233.90.72: icmp_seq=0 ttl=47 time=208.013 ms 64 bytes from 199.233.90.72: icmp_seq=1 ttl=47 time=256.441 ms 64 bytes from 199.233.90.72: icmp_seq=2 ttl=47 time=281.436 ms 64 bytes from 199.233.90.72: icmp_seq=3 ttl=47 time=281.103 ms 64 bytes from 199.233.90.72: icmp_seq=4 ttl=47 time=285.440 ms [...] --- avalon.dragonflybsd.org ping statistics --- 19 packets transmitted, 19 packets received, 0.0% packet loss round-trip min/avg/max/stddev = 208.013/264.017/334.180/31.549 ms Now, navigate to `/usr/local/etc/pkg/repos/` and rename one of the configuration file samples you find there.

Each __pkgng__ command argument is documented in a command-specific manual page. To read the manual page for `pkg install`, for example, run either: # pkg help install # man pkg-install ## Obtaining Information About Installed Packages with pkgng Information about the packages installed on a system can be viewed by running `pkg info`. Similar to pkg_info(1), the package version and description for all packages will be listed. Information about a specific package is available by running: # pkg info packagename For example, to see which version of __pkgng__ is installed on the system, run: # pkg info pkg pkg-1.0.12 New generation package manager ## Installing and Removing Packages with pkgng In general, most DragonFly users will install binary packages by typing: # pkg install For example, to install curl: # pkg install curl Updating repository catalogue Repository catalogue is up-to-date, no need to fetch fresh copy The following packages will be installed: Installing ca_root_nss: 3.13.5 Installing curl: 7.24.0 The installation will require 4 MB more space 1 MB to be downloaded Proceed with installing packages [y/N]: y ca_root_nss-3.13.5.txz 100% 255KB 255.1KB/s 255.1KB/s 00:00 curl-7.24.0.txz 100% 1108KB 1.1MB/s 1.1MB/s 00:00 Checking integrity... done Installing ca_root_nss-3.13.5... done Installing curl-7.24.0... done The new package and any additional packages that were installed as dependencies can be seen in the installed packages list: # pkg info ca_root_nss-3.13.5 The root certificate bundle from the Mozilla Project curl-7.24.0 Non-interactive tool to get files from FTP, GOPHER, HTTP(S) servers pkg-1.0.12 New generation package manager Packages that are no longer needed can be removed with `pkg delete`. For example, if it turns out that curl is not needed after all: # pkg delete curl The following packages will be deleted: curl-7.24.0_1 The deletion will free 3 MB Proceed with deleting packages [y/N]: y Deleting curl-7.24.0_1... done ## Upgrading Installed Packages with pkgng Packages that are outdated can be found with `pkg version`. If a local ports tree does not exist, pkg-version(8) will use the remote repository catalogue, otherwise the local ports tree will be used to identify package versions. Packages can be upgraded to newer versions with __pkgng__. Suppose a new version of curl has been released. The local package can be upgraded to the new version: # pkg upgrade Updating repository catalogue repo.txz 100% 297KB 296.5KB/s 296.5KB/s 00:00 The following packages will be upgraded: Upgrading curl: 7.24.0 -> 7.24.0_1 1 MB to be downloaded Proceed with upgrading packages [y/N]: y curl-7.24.0_1.txz 100% 1108KB 1.1MB/s 1.1MB/s 00:00 Checking integrity... done Upgrading curl from 7.24.0 to 7.24.0_1... done ## Auditing Installed Packages with pkgng Occasionally, software vulnerabilities may be discovered in software within DPorts. __pkgng__ includes built-in auditing. To audit the software installed on the system, type: # pkg audit -F # Advanced pkgng Operations ## Automatically Removing Leaf Dependencies with pkgng Removing a package may leave behind unnecessary dependencies, like `security/ca_root_nss` in the example above. Such packages are still installed, but nothing depends on them any more. Unneeded packages that were installed as dependencies can be automatically detected and removed: # pkg autoremove Packages to be autoremoved: ca_root_nss-3.13.5 The autoremoval will free 723 kB Proceed with autoremoval of packages [y/N]: y Deinstalling ca_root_nss-3.13.5... done ## Backing Up the pkgng Package Database __pkgng__ includes its own package database backup mechanism. To manually back up the package database contents, type: # pkg backup -d Additionally, __pkgng__ includes a periodic(8) script to automatically back up the package database daily if `daily_backup_pkgng_enable` is set to `YES` in periodic.conf(5). To prevent the `pkg_install` periodic script from also backing up the package database, set `daily_backup_pkgdb_enable` to `NO` in periodic.conf(5). To restore the contents of a previous package database backup, run: # pkg backup -r ## Removing Stale pkgng Packages By default, __pkgng__ stores binary packages in a cache directory as defined by `PKG_CACHEDIR` in pkg.conf(5). When upgrading packages with pkg upgrade, old versions of the upgraded packages are not automatically removed. To remove the outdated binary packages, type: # pkg clean ##Modifying pkgng Package Metadata __pkgng__ has a built-in command to update package origins. For example, if `lang/php5` was originally at version 5.3, but has been renamed to lang/php53 for the inclusion of version 5.4, the package database can be updated to deal with this. For __pkgng__, the syntax is: # pkg set -o : For example, to change the package origin for the above example, type: # pkg set -o lang/php5:lang/php53 As another example, to update lang/ruby18 to lang/ruby19, type: # pkg set -o lang/ruby18:lang/ruby19 As a final example, to change the origin of the libglut shared libraries from graphics/libglut to graphics/freeglut, type: # pkg set -o graphics/libglut:graphics/freeglut _Note_: When changing package origins, in most cases it is important to reinstall packages that are dependent on the package that has had the origin changed. To force a reinstallation of dependent packages, type: # pkg install -Rf graphics/freeglut # Building DPorts from source The average user will probably not build packages from source. However, it's easy to do and it can be done even when packages have already been pre-installed on the system. Common reasons to build from source are: * The port is new and there's no pre-binary available yet * The pre-built binaries use the default options and the user needs a package built with a different set of options * Testing FreeBSD port in order to patch them and submit to DPorts * The user just prefers building from source ## Installing DPorts tree DragonFly 3.4 or later is the minimum version that can build DPorts from source. It's probably that pkgsrc binaries are already installed because it comes bootstrapped with new systems. It is necessary to rename `/usr/pkg` directory so that the existing pkgsrc binary tools and libraries don’t get accidentally used while building DPorts, causing breakage. For the installation of the DPorts tree, type: # cd /usr # make dports-create-shallow If the `/usr/pkg directory` has already been renamed, `git` won’t be in the search path any more. One option is to download a tarball of DPorts and unpack it. To do this, type: # cd /usr # make dports-download For future updates, pull delta changes via `git` is fastest, so it is suggested to convert the static tree to a git repository by typing: # cd /usr/dports/devel/git # make install # cd /usr # rm -rf /usr/dports # make dports-create-shallow The git repository is hosted on the [github account of John Marino](https://github.com/jrmarino/DPorts/#readme). ## Final thoughts Building from source works similar to ports and pkgsrc: cd into the appropriate program's directory, and type 'make'. 'make install' to install the software, 'make clean' to clean up work files, and so on. Use 'make config-recursive' if you want to set all the port's options, and the options of its dependencies, immediately instead of during the build. To take all the default build options and avoid getting the pop-up dialog box, set `NO_DIALOG=yes` on either the command line or the make.conf file. If you just want to set the options for one package, and accept the default for all of its dependencies, do 'make config' in the package in you want non-default options, and then 'make NO_DIALOG=yes'. Note that this is only necessary if you want to build from source with a non-default set of options, or if no pre-built binary package is available yet. ## More reading * How fix/add broken ports: [[docs/howtos/fixdports]] * [Trick: How to get i386-only software via dports](http://leaf.dragonflybsd.org/mailarchive/users/2013-06/msg00023.html)
