Usage: ${0##*/} [ options ] [input-file] |
|
|
|
Read input-file which is a git or bzr log and create a |
|
debian/changelog formatted file from the result. |
|
|
|
options: |
|
--vcs VCS which log format is this ('git', 'auto', 'bzr') |
|
default: auto |
|
|
|
|
|
Assuming git style log commit messages, this reads the makes the |
|
summary line into a debian/changelog style entry with author |
|
in [] and mentions bugs fixed (bzr via '--fixes', git via LP: # |
|
in commit messages.) |
|
|
|
Examples: |
|
|
|
* bzr based simplestreams (bzr branch lp:simplestreams) |
|
|
|
$ bzr log -r-5.. | log2dch |
|
- Keystone v3 Support (LP: #1686437) |
|
- tools/ubuntu_versions.py: Exclude old versions by version not name |
|
- fix flake8 |
|
- tests: change to having http server select its own port |
|
- flake8: fix style errors reported by pycodestyle 2.1.0 |
|
|
|
* git based cloud-init (git clone http://git.launchpad.net/cloud-init) |
|
|
|
$ git log HEAD~5.. | log2dch |
|
- tests: execute: support command as string [Joshua Powers] |
|
- schema and docs: Add jsonschema to resizefs and bootcmd modules |
|
[Chad Smith] |
|
- tools: Add xkvm script, wrapper around qemu-system [Joshua Powers] |
|
- vmware customization: return network config format |
|
[Sankar Tanguturi] (LP: #1675063) |
|
- Ec2: only attempt to operate at local mode on known platforms. |
