Repository

I found very few reference about repository in xbps.

Configuration

Configuration can be found in /usr/share/xbps.d

$ cat /usr/share/xbps.d/00-repository-main.conf 
repository=https://repo.voidlinux.eu/current

Consider check the sign.

$ xbps-query -vL
 8242 https://repo.voidlinux.eu/current (RSA signed)
      Signed-by: Void Linux
      4096 60:ae:0c:d6:f0:95:17:80:bc:93:46:7a:89:af:a3:2d

Docker XBPS: Repository: Install

Add Subrepository

Sub-repositories can be found as packages.

$ xbps-query -Rs void-repo
[-] void-repo-debug-9_1            Void Linux drop-in file for t...
[-] void-repo-multilib-6_1         Void Linux drop-in file for t...
[-] void-repo-multilib-nonfree-6_1 Void Linux drop-in file for t...
[-] void-repo-nonfree-9_1          Void Linux drop-in file for t...

Docker XBPS: Repository: Query

Therefore a sub-repository can be installed as package.

xbps-install void-repo-nonfree
1 package will be downloaded:
  void-repo-nonfree-9_1 
1 package will be installed:
  void-repo-nonfree-9_1 

Size to download:              1284B
Size required on disk:         1337B
Free space on disk:             22GB

Docker XBPS: Repository: Configuration

Do not forget to obey the official manual to synchronize

$ xbps-install -S

x86_64-repodata: 1315KB [avg rate: 1228KB/s]

Docker XBPS: Repository: Synchronize

List Packages

Now we can list avaliable packages from that repository.

$ cat /usr/share/xbps.d/10-repository-nonfree.conf

Mirror

We can adjust the mirror by changing the configuration.

$ cat /usr/share/xbps.d/00-repository-main.conf 
repository=https://repo.voidlinux.eu/current
$ xbps-install -S
[*] Updating 'https://repo.voidlinux.eu/current/x86_64-repodata' ...

$ xbps-install -S

Verify Database

There is this xbps-pkgdb --all command.

$ xbps-pkgdb -a
ERROR: xbps: hash mismatch for /usr/share/xbps.d/00-repository-main.conf.
ERROR: xbps: files check FAILED.

/var/db/xbps

You can also examine any .plist in this directory

  • /var/db/xbps/pkgdb- * .plist
$ head /var/db/xbps/pkgdb-0.38.plist

Orphan Packages

$ xbps-query -o
$ xbps-query --list-orphans

Currently, no orphan this time.

History

The Log File

Unfortunately, nothing in /var/log

$ ls -l /var/log/
total 0

Clean Up

Time after time, your cache size may growing bigger and bigger.

Package Cache

  • /var/cache/xbps/ * .xbps
$ ls -lR  /var/cache/xbps/

Docker XBPS: Cache

You can clean these directory. Unused package will be removed. Some other stay.

$ xbps-remove -O
Removed file-5.30_1.x86_64.xbps from cachedir (obsolete)
Removed diffutils-3.5_2.x86_64.xbps from cachedir (obsolete)
Removed libtls15-2.5.4_1.x86_64.xbps from cachedir (obsolete)
Removed iproute2-4.10.0_1.x86_64.xbps from cachedir (obsolete)

Docker XBPS: Clean

Build from Source

This part is about xbps-src.

Reading

Requirement

First we need xtools. Later we will need qemu and gcc, or maybe proot.

$ xbps-install xtools
2 packages will be downloaded:
  libpcre2-10.30_1 expat-2.2.4_1 
5 packages will be installed:
  libpcre2-10.30_1 expat-2.2.4_1 git-2.14.1_1 
  make-4.2.1_3 xtools-0.48_1 

Size to download:              418KB
Size required on disk:          33MB
Free space on disk:             22GB

Docker XBPS-SRC: Void Packages

Consider to change working directory.

$ cd ~/void-packages/

Getting Help

Read The Fine Manual. As usual.

$ ./xbps-src     
xbps-src: [options] <target> [arguments]

Targets: (only one may be specified)

binary-bootstrap [arch]
    Install bootstrap packages from host repositories into <masterdir>.
    If the optional 'arch' argument is set, it will install bootstrap packages
    from this architecture, and its required xbps utilities. The <masterdir>
    will be initialized for chroot operations.

Docker XBPS-SRC: Binary Bootstrap

Now we should be ready to use xbps-src.

Under Docker

Unfortunately my host kernel does not support feature required by xbps-src.

Hold

Hold in xbps is pretty straightforward.

Example

Consider a system upgrade, we choose to hold nano and mc as our guinea pig example.

$ xbps-install -Su
[*] Updating 'https://repo.voidlinux.eu/current/x86_64-repodata' ...
x86_64-repodata: 1332KB [avg rate: 814KB/s]
18 packages will be downloaded:
  bc-1.07.1_2 btrfs-progs-4.13_1 ca-certificates-20170717_1 
  dash-0.5.9.1_2 dhcpcd-6.11.5_4 dnssec-anchors-20170822_1 
  e2fsprogs-1.43.6_1 e2fsprogs-libs-1.43.6_1 
  glibc-locales-2.26_2 libcap-ng-0.7.8_3 libharfbuzz-1.5.1_1 
  mc-4.8.19_2 nano-2.8.7_1 nghttp2-1.25.0_1 qemu-2.10.0_1 
  runit-2.1.2_8 runit-void-20170907_1 sudo-1.8.21p2_1 
18 packages will be updated:
  bc (1.07.1_1 -> 1.07.1_2) btrfs-progs (4.12_1 -> 4.13_1) 
  ca-certificates (20161130+nmu1_1 -> 20170717_1) 
...

Lock Package

$ xbps-pkgdb -m hold nano mc

Docker XBPS: Hold

Result

We can see there is no more mc and nano.

$ xbps-install -Su
[*] Updating 'https://repo.voidlinux.eu/current/x86_64-repodata' ...
16 packages will be downloaded:
  bc-1.07.1_2 btrfs-progs-4.13_1 ca-certificates-20170717_1

Unlock Package

$ xbps-pkgdb -m unhold nano mc

Conclusion

There are still things that I do not understand, such as using xbps-src.
