svn

Introduction

svn is a simple Subversion library for Python. I wrote it so that there could be a lightweight and accessible library that was also available on PyPI. It is compatible with both Python 2.7 and 3.3+.

The library wraps the svn commandline client, which should consequently be installed on the local system.

Functions currently implemented:

• list
• info
• log
• checkout
• export
• cat
• diff
• diff_summary
• status
• add
• commit
• update
• cleanup

In addition, there is also an "admin" class (svn.admin.Admin) that provides a create method with which to create repositories.

You are more than welcome to submit pull-requests to add more support for additional subcommands.

Usage

Usage is divided between two clients that either allow for access to a local working-directory or a remote repository.

Both clients inherit a common set of methods that work with both local working- directories and remote repositories.

svn.utility.get_client is provided for convenience. If you provide a location that starts with a backslash, it will return a LocalClient instance. Otherwise, it will return a RemoteClient instance.

You may pass username and password as optional arguments to both the constructor and utility function.

LocalClient

LocalClient allows access to a local working copy.

RemoteClient

RemoteClient allows access to a remote repository.

SvnException

SvnException is raised whenever there is an issue with the svn repository. We are no longer supporting catching ValueError.

checkout(path)

Checkout a remote repository:

import svn.remote

r = svn.remote.RemoteClient('https://repo.local/svn')
r.checkout('/tmp/working')

Common Functionality

These methods are available on both clients.

info(rel_path=None)

Get information about the directory.

import pprint

import svn.local

r = svn.local.LocalClient('/tmp/test_repo.co')
info = r.info()
pprint.pprint(info)

#{'commit#revision': 0,
# 'commit/author': None,
# 'commit/date': datetime.datetime(2015, 4, 24, 2, 53, 21, 874970, tzinfo=tzutc()),
# 'commit_author': None,
# 'commit_date': datetime.datetime(2015, 4, 24, 2, 53, 21, 874970, tzinfo=tzutc()),
# 'commit_revision': 0,
# 'entry#kind': 'dir',
# 'entry#path': '/tmp/test_repo.co',
# 'entry#revision': 0,
# 'entry_kind': 'dir',
# 'entry_path': '/tmp/test_repo.co',
# 'entry_revision': 0,
# 'relative_url': None,
# 'repository/root': 'file:///tmp/test_repo',
# 'repository/uuid': '7446d4e9-8846-46c0-858a-34a2a1739d1c',
# 'repository_root': 'file:///tmp/test_repo',
# 'repository_uuid': '7446d4e9-8846-46c0-858a-34a2a1739d1c',
# 'url': 'file:///tmp/test_repo',
# 'wc-info/depth': None,
# 'wc-info/schedule': None,
# 'wc-info/wcroot-abspath': None,
# 'wcinfo_depth': None,
# 'wcinfo_schedule': None,
# 'wcinfo_wcroot_abspath': None}

NOTE: The keys named with dashes, slashes, and hashes are considered obsolete, and only available for backwards compatibility. We have since moved to using only underscores to separate words.

cat(rel_filepath)

Get file-data as string.

import svn.local

l = svn.local.LocalClient('/tmp/test_repo')
content = l.cat('test_file')

log_default(timestamp_from_dt=None, timestamp_to_dt=None, limit=None, rel_filepath='', stop_on_copy=False, revision_from=None, revision_to=None, changelist=False)

Perform a log-listing that can be bounded by time or revision number and/or take a maximum-count.

import svn.local

l = svn.local.LocalClient('/tmp/test_repo.co')

for e in l.log_default():
    print(e)

#LogEntry(date=datetime.datetime(2015, 4, 24, 3, 2, 39, 895975, tzinfo=tzutc()), msg='Added second file.', revision=2, author='dustin')
#LogEntry(date=datetime.datetime(2015, 4, 24, 2, 54, 2, 136170, tzinfo=tzutc()), msg='Initial commit.', revision=1, author='dustin')

export(to_path, revision=None, force=False)

Checkout the tree without embedding an meta-information.

import svn.remote

r = svn.remote.RemoteClient('file:///tmp/test_repo')
r.export('/tmp/test_export')

We can also use force option to force the svn export.

list(extended=False, rel_path=None)

Return either a flat-list of filenames or a list of objects describing even more information about each.

import pprint

import svn.local

l = svn.local.LocalClient('/tmp/test_repo.co')

# Flat list.

entries = l.list()
for filename in entries:
    print(filename)

#aa
#bb

# Extended information.

entries = l.list(extended=True)
for entry in entries:
    pprint.pprint(entry)

#{'author': 'dustin',
# 'commit_revision': 1,
# 'date': datetime.datetime(2015, 4, 24, 2, 54, 2, 136170, tzinfo=tzutc()),
# 'is_directory': False,
# 'kind': 'file',
# 'name': 'aa',
# 'size': 0,
# 'timestamp': datetime.datetime(2015, 4, 24, 2, 54, 2, 136170, tzinfo=tzutc())}
#{'author': 'dustin',
# 'commit_revision': 2,
# 'date': datetime.datetime(2015, 4, 24, 3, 2, 39, 895975, tzinfo=tzutc()),
# 'is_directory': False,
# 'kind': 'file',
# 'name': 'bb',
# 'size': 0,
# 'timestamp': datetime.datetime(2015, 4, 24, 3, 2, 39, 895975, tzinfo=tzutc())}

list_recursive(rel_path=None, yield_dirs=False, path_filter_cb=None)

List all entries at and beneath the root or given relative-path.

import pprint

import svn.local

l = svn.local.LocalClient('/tmp/test_repo.co')

for rel_path, e in l.list_recursive():
    print('')
    print('[' + rel_path + ']')
    print('')

    pprint.pprint(e)

#{'author': 'dustin',
# 'commit_revision': 1,
# 'date': datetime.datetime(2015, 4, 24, 2, 54, 2, 136170, tzinfo=tzutc()),
# 'is_directory': False,

# 'timestamp': datetime.datetime(2015, 4, 24, 3, 25, 13, 479212, tzinfo=tzutc())}

diff_summary(start_revision, end_revision)

A lower-level diff summary that doesn't actually provide the content differences.

import svn.remote

l = svn.remote.RemoteClient('http://svn.apache.org/repos/asf')
print l.diff_summary(1760022, 1760023)

# [{'item': 'modified',
#  'kind': 'file',
#  'path': 'http://svn.apache.org/repos/asf/sling/trunk/pom.xml'},
# {'item': 'added',
#  'kind': 'file',
#  'path': 'http://svn.apache.org/repos/asf/sling/trunk/bundles/extensions/models/pom.xml'}]

diff(start_revision, end_revision)

Diffs between start and end revisions

Notice of Diff Reimplementation in 1.0.0

There was a previous contribution to the diff implementation that has been reported and confirmed to often throw an exception due to shoddy handling of the file-paths in the output. It also made secondary shell calls and mixed both text and XML output in the response. As a result of this, the decision has been made to just reimplement it and reshape the output in a backwards-incompatible way at the same time. If you need to stick to the older implementation, tie your dependencies to the 0.3.46 release.
