The new build script, ci.go, replaces some of the older shell scripts. ci.go can compile go-ethereum, run the tests, create release archives and debian source packages.pull/2726/head

Debian Packaging |
||||
---------------- |
||||
|
||||
Tagged releases and develop branch commits are available as installable Debian packages |
||||
for Ubuntu. Packages are built for the all Ubuntu versions which are supported by |
||||
Canonical: |
||||
|
||||
- Trusty Tahr (14.04 LTS) |
||||
- Wily Werewolf (15.10) |
||||
- Xenial Xerus (16.04 LTS) |
||||
|
||||
Packages of develop branch commits have suffix -unstable and cannot be installed alongside |
||||
the stable version. Switching between release streams requires user intervention. |
||||
|
||||
The packages are built and served by launchpad.net. We generate a Debian source package |
||||
for each distribution and upload it. Their builder picks up the source package, builds it |
||||
and installs the new version into the PPA repository. Launchpad requires a valid signature |
||||
by a team member for source package uploads. The signing key is stored in an environment |
||||
variable which Travis CI makes available to certain builds. |
||||
|
||||
We want to build go-ethereum with the most recent version of Go, irrespective of the Go |
||||
version that is available in the main Ubuntu repository. In order to make this possible, |
||||
our PPA depends on the ~gophers/ubuntu/archive PPA. Our source package build-depends on |
||||
golang-1.6, which is co-installable alongside the regular golang package. PPA dependencies |
||||
can be edited at https://launchpad.net/%7Elp-fjl/+archive/ubuntu/geth-ci-testing/+edit-dependencies |

The ci command is called from Continuous Integration scripts. |

Usage: go run ci.go <command> <command flags/arguments> |

|

Available commands are: |

|
||||
install [ packages... ] -- builds packages and executables |
||||
test [ -coverage ] [ -vet ] [ packages... ] -- runs the tests |
||||
archive [ -type zip|tar ] -- archives build artefacts |
||||
importkeys -- imports signing keys from env |
||||
debsrc [ -sign key-id ] [ -upload dest ] -- creates a debian source package |
||||
|

For all commands, -n prevents execution of external programs (dry run mode). |
