# 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 (with raw and summary support)

- status

- add

- commit

- update

- cleanup

- remove (i.e. rm, del, delete)



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,

# 'kind': 'file',

# 'name': 'aa',

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

# 'size': 0,

# '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.
