hg-importfs 1.3.2

import a set of files from a file-system into a repository

Imports a set of files from a given file-system into a Mercurial repository as a changeset.

The development of this extension was paid for by Lantiq. It was written and released as Open Source by Markus Zapke-Gründemann.

Repository: https://bitbucket.org/keimlink/hg-importfs

Issue tracker: https://bitbucket.org/keimlink/hg-importfs/issues

Python Package Index: http://pypi.python.org/pypi/hg-importfs

Mercurial wiki: http://mercurial.selenic.com/wiki/ImportfsExtension

Installation

It is assumed that you already have Mercurial installed. If not, please do so first either by downloading and installing the appropriate package for your operating system or by using pip:

$ pip install Mercurial

As a Python package

The easiest way is to install the importfs extension is to use pip:

$ pip install hg-importfs

Using easy_install instead of pip is also possible:

$ easy_install hg-importfs

Now add the extension to the extensions section in your .hgrc/mercurial.ini file:

[extensions]
importfs =

As a Mercurial repository

Instead of installing the Python package you can also clone the repository:

$ hg clone https://bitbucket.org/keimlink/hg-importfs

To activate the extension you have to add the full path to importfs.py to your .hgrc/mercurial.ini file:

[extensions]
importfs = /path/to/hg-importfs/importfs.py

Usage

After installing the extension you can use the following command to show the full help including all options:

$ hg help importfs

Example

Assuming you have a project on your file system which has different versions in different directories. Maybe because you never used a version control system (VCS) for your project. Or maybe because there is no convert extension available for the VCS you are using. In our scenario the three versions of the project look like this:

.
├── myproject-v1
│   ├── LICENSE
│   ├── README
│   ├── doc
│   │   ├── index.rst
│   │   ├── start.rst
│   │   └── widgets.rst
│   └── src
│       ├── cmdutils.py
│       ├── dispatcher.py
│       └── widgets.py
├── myproject-v2
│   ├── LICENSE
│   ├── README
│   ├── doc
│   │   ├── index.rst
│   │   ├── start.rst
│   │   └── widgets.rst
│   └── src
│       ├── cmdutils.py
│       ├── dispatcher.py
│       ├── resources.py
│       └── widgets.py
└── myproject-v3
    ├── LICENSE
    ├── README
    ├── doc
    │   ├── index.rst
    │   ├── start.rst
    │   └── widgets.rst
    └── src
        ├── dispatcher.py
        ├── resources.py
        └── widgets.py

Run the following command to import the first version of the project into a Mercurial repository myrepo. The repository does not exist so it will be created for you:

$ hg importfs myrepo myproject-v1
created repository myrepo
0 files updated, 0 files merged, 0 files removed, 0 files unresolved
adding LICENSE
adding README
adding doc/index.rst
adding doc/start.rst
adding doc/widgets.rst
adding src/cmdutils.py
adding src/dispatcher.py
adding src/widgets.py

Now you have a repository with one changeset. This changeset contains all your files from myproject-v1.

$ hg log -R myrepo
changeset:   0:60304fa41a49
tag:         tip
user:        Markus Zapke-Gründemann <markus@keimlink.de>
date:        Tue Jul 10 10:19:10 2012 +0200
summary:     importfs commit.

As you can see importfs created a commit message for you because you didn't specify one for the first import.

The second import will put all the files from myproject-v2 as a new changeset on top of changeset 0. And this time we want to use our own commit message and tag the changeset:

$ hg importfs myrepo myproject-v2 -m "Second import." -t second_import
8 files updated, 0 files merged, 0 files removed, 0 files unresolved
adding src/resources.py

Now there are two new changesets:

$ hg log -R myrepo
changeset:   2:c8ff824da6c8
tag:         tip
user:        Markus Zapke-Gründemann <markus@keimlink.de>
date:        Tue Jul 10 10:27:10 2012 +0200
summary:     Added tag second_import for changeset 825c9a9356fd

changeset:   1:825c9a9356fd
tag:         second_import
user:        Markus Zapke-Gründemann <markus@keimlink.de>
date:        Tue Jul 10 10:27:10 2012 +0200
summary:     Second import.

changeset:   0:60304fa41a49
user:        Markus Zapke-Gründemann <markus@keimlink.de>
date:        Tue Jul 10 10:19:10 2012 +0200
summary:     importfs commit.

Let's import the last version of the project into a new branch with changeset 0 as parent:

$ hg importfs myrepo myproject-v3 -m "Third import." -t third_import -b branch_2 -r 0
8 files updated, 0 files merged, 1 files removed, 0 files unresolved
marked working directory as branch branch_2
(branches are permanent and global, did you want a bookmark?)
removing src/cmdutils.py
adding src/resources.py

The repository history looks now like this:

$ hg glog -R myrepo

|  tag:         tip

How to set up a development environment

If you havn't created a clone of the importfs repository yet it's time to do it now:

$ hg clone https://bitbucket.org/keimlink/hg-importfs

Setup a virtualenv

The best way to do the development is to use a virtualenv. So first create one using virtualenvwrapper:

$ mkvirtualenv --distribute hg-importfs

Then install all packages needed for development into the virtualenv using pip:

(hg-importfs)$ cd hg-importfs
(hg-importfs)$ pip install -r requirements.txt

You also need a clone of the hg repository:

(hg-importfs)$ cd ..
(hg-importfs)$ hg clone http://selenic.com/repo/hg

Update to your desired version (if you don't want to use tip) and build for local use:

(hg-importfs)$ cd hg
(hg-importfs)$ hg up VERSION
(hg-importfs)$ make local

After creating the clone create a few symlinks in your importfs repository:

(hg-importfs)$ cd ../hg-importfs
(hg-importfs)$ ln -s ../hg/contrib/pylintrc
(hg-importfs)$ ln -s ../hg/tests/hghave
(hg-importfs)$ ln -s ../hg/tests/run-tests.py

Finally add the hg directory to your virtualenv:

(hg-importfs)$ add2virtualenv ../hg

Run the tests

To run all tests you can now execute the following command:

(hg-importfs)$ ./run-tests.py -l

Create a new source distribution package

A new Python source distribution package can be created using this command:

(hg-importfs)$ python setup.py sdist
