New in v0.7.18 (2018/0?/??)

---------------------------

* Fixed bug #1756550 Online html man page is showing a 0 byte file

* Partial fix of bug #1734144 with patch from Joris van Eijden

  - Note: this is really just a partial fix for now, since it only covers

    the case where the local size does not yet match the remote size.  A

    case where -1 is the returned length is not fixed.

  - Number of retries is now same as globals.num_retries.

  - Added standoff delay of 0.5 sec per attempt.

* Fixed bug #1764432 with patch from Robke Geenen

  - Just join the parts together.

* Fixed bug #1717935 with suggestion from strainu

  - Use urllib.quote_plus() to properly quote pathnames passed via URL

* Fixed bug #1780617 Test fail when GnuPG >= 2.2.8

  - Relevant change in GnuPG 2.2.8: https://dev.gnupg.org/T3981

  - Added '--ignore-mdc-error' to all gpg calls made.

New in v0.7.17 (2018/02/26)

---------------------------

* Removed changes made in bug #1044715 Provide a file history feature

  - Changes required too much memory to carry in the manifest

  - The option --file-changed in collection-status is now invalid

  - This will close bugs: #1730451, #896728, #1526557, #1550176

  - Starting a full backup will be needed to fully utilize this fix

* Fix update of Launchpad Translations.  Translations were not being picked

  up on a daily basis and we got several months behind.

New in v0.7.16 (2018/01/12)

---------------------------

* Fixed bug #1733057 AttributeError: 'GPGError' object has no attribute 'decode'

  - Replaced call to util.ufn() with call to util.uexc().  Stupid typo!

* More fixes for Unicode handling

  - Default to 'utf-8' if sys.getfilesystemencoding() returns 'ascii' or None

  - Fixed bug #1386373 with suggestion from Eugene Morozov

* Patched in lp:~crosser/duplicity/fix-oauth-flow

  - Fixed bug #1638236 "BackendException with oauth2client 4.0.0"

* Patched in lp:~crosser/duplicity/dpbx-fix-file-listing

  - Fixed bug #1639664 "Dropbox support needs to be updated for Dropbox SDK v7.1"

* Patched in lp:~crosser/duplicity/fix-small-file-upload

  - Fixed small file upload changes made in Dropbox SDK v7.1

* Fix pylint error in webdavbackend.py

New in v0.7.15 (2017/11/13)

---------------------------

* Fixed bug introduced in new megabackend.py where process_commandline()

  takes a string not a list.  Now it takes both.

* Updated web page for new megabackend requirements.

* Patched in lp:~mterry/duplicity/more-decode-issues

  - Here's some fixes for another couple UnicodeDecodeErrors.

  - The duplicity/dup_time.py fixes when a user passes a utf8 date string (or a string with bogus

    utf8 characters, but they have to really try to do that). This is bug 1334436.

  - The bin/duplicity change from str(e) to util.uexc(e) fixes bug 1324188.

  - The rest of the changes (util.exception_traceback and bin/duplicity changes to use it) are to

    make the printing of exceptions prettier. Without this, if you see a French exception, you see

    "accept\xe9es" instead of "acceptées".

  - You can test all of these changes in one simple line:

    $ LANGUAGE=fr duplicity remove-older-than $'accept\xffées'

* Fix backend.py to allow string, list, and tuple types to support megabackend.py.

* Fixed bug #1715650 with patch from Mattheww S

  - Fix to make duplicity attempt a get first, then create, a container

    in order to support container ACLs.

* Fixed bug #1714663 "Volume signed by XXXXXXXXXXXXXXXX, not XXXXXXXX"

  - Normalized comparison length to min length of compared keys before comparison

  - Avoids comparing mix of short, long, or fingerprint size keys.

* Merged in lp:~mterry/duplicity/rename-dep

  - Make rename command a dependency for LP build

* Fixed bug #1654756 with new b2backend.py module from Vincent Rouille

  - Faster (big files are uploaded in chunks)

  - Added upload progress reporting support

* Fixed bug #1448094 with patch from Wolfgang Rohdewald

  - Don't log incremental deletes for chains that have no incrementals

* Fixed bug #1724144 "--gpg-options unused with some commands"

  - Add --gpg-options to get version run command

* Fixed bug #1720159 - Cannot allocate memory with large manifest file since 0.7.03

  - filelist is not read if --file-changed option in collection-status not present

  - This will keep memory usage lower in non collection-status operations

* Fixed bug #1723890 with patch from Killian Lackhove

  - Fixes error handling in pydrivebackend.py

* Fixed bug #1730902 GPG Error Handling

  - use util.ufn() not str() to handle encoding

New in v0.7.14 (2017/08/31)

---------------------------

* Merged in lp:~dawgfoto/duplicity/skip_sync_collection_status

  - collection-status should not sync metadata

  - up-to-date local metadata is not needed as collection-status is

    generated from remote file list

  - syncing metadata might require to download several GBs

* Fixed slowness in 'collection-status' by basing the status on the

  remote system only.  The local cache is treated as empty.

* Fixed encrypted remote manifest handling to merely put out a non-fatal

  error message and continue if the private key is not available.

* Patched in lp:~mterry/duplicity/giobackend-display-name

  - giobackend: handle a wider variety of gio backends by making less assumptions;

    in particular, this fixes the google-drive: backend

* Fixed bug #1709047 with suggestion from Gary Hasson

  - fixed so default was to use original filename

* Fixed PEP8 errors in bin/duplicity

* Merged in lp:~mterry/duplicity/gio_child_for_display_name_0.7

  - gio: be slightly more correct and get child GFiles based on display name

* Fixed bug #1711905 with suggestion from Schneider

  - log.Warn was invoked with log.warn in webdavbackend.py

* Merged in lp:~mterry/duplicity/gpg-tag-versions

  - Support gpg versions numbers that have tags on them.

  - This can happen if you build gpg from git trunk (e.g. 2.1.15-beta20). Or if you run

    against the freedesktop flatpak runtime (e.g. 2.1.14-unknown).

* Fixed bug #1394386 with new module megabackend.py from Tomas Vondra

  - uses megatools from https://megatools.megous.com/ instead of mega.py library

    which has been deprecated

  - fixed copyright and PEP8 issues

  - replaced subprocess.call() with self.subprocess_popen() to standardize

* Fixed bug #1713640 with patch from Aleksandar Ivanisevic

  - replace 2.7 syntax with 2.6 equivalent

* Fixed bug #1538333 Assertion error in manifest.py: assert filecount == ...

  - Made sure to never pass .part files as true manifest files

  - Changed assert to log.Error to warn about truncated/corrupt filelist

  - Added unit test to make sure detection works

  - Note: while this condition is serious, it will not affect the basic backup and restore

    functions.  Interactive options like --list-files-changed and --file-changed will not

    work correctly for this backup set, so it is advised to run a full backup as soon as

    possible after this error occurs.

* Fixed bug #1638033 Remove leading slash on --file-to-restore

  - code already used rstrip('/') so change to just strip('/')

New in v0.7.13.1 (2017/06/18)

-----------------------------

* Fixed problem in dist/makedist when building on Mac where AppleDouble

  files were being created in the tarball.  See:

  https://superuser.com/questions/61185/why-do-i-get-files-like-foo-in-my-tarball-on-os-x

New in v0.7.13 (2017/06/12)

---------------------------

* Fixed bug #1680682 with patch supplied from Dave Allan

  - Only specify --pinentry-mode=loopback when --use-agent is not specified

* Fixed man page that had 'cancel' instead of 'loopback' for pinentry mode

* Fixed bug #1684312 with suggestion from Wade Rossman

  - Use shutil.copyfile instead of os.system('cp ...')

  - Should reduce overhead of os.system() memory usage.

* Fixed bug #1320832 with suggestion from Oskar Wycislak

  - Use chunks instead of reading it all in swiftbackend

* Fixed bug #1689632 with patch from Howard Kaye

  - On MacOS, the tempfile.TemporaryFile call erroneously raises an

    IOError exception saying that too many files are open. This causes

    restores to fail randomly, after thousands of files have been restored.

* Fixed bug #1320641 and others regarding lockfile

  - swap from lockfile to fasteners module

  - use an fcntl() style lock for process lock of duplicity cache

  - lockfile will now clear if duplicity is killed or crashes

* May have finally fixed bug #1556553, "Too many open files...".

  - Applied patch from Howard Kaye, question #631423.  The fix is to dup

    the file descriptor, and then close the file in the deallocator

    routine in the glue code. Duping the file lets the C code and the Python

    code each close the file when they are done with it.

  - Invalidated and removed the fix put in for bug #1320832.

  - Caveat: long incremental chains will still eat up a large number of file

    descriptors.  It's a very risky practice, so I'm not inclined to fix it.

* Revisited bug #670891 with patch from Edgar Soldin

  - Forced librsync.PatchedFile() to extract file object from TemporaryFile()

    object when on Windows or Cygwin systems.  This allows us to avoid the

    problem of tmpfile() use which creates temp files in the wrong place.

  - See discussion at https://bugs.launchpad.net/duplicity/+bug/670891

* Fix bug #1672540 with patch from Benoit Nadeau

  - Rename would fail to move par files when moving across filesystems.

  - Patch uses shutil.move() to do the rename instead.

* Fixed bug #1265765 with patches from Matthias Larisch and Edgar Soldin

  - SSH Paramiko backend now uses BufferedFile implementation to enable

    collecting the entire list of files on the backend.

* Copy.com is gone so remove copycombackend.py.

* Merged in lp:~xlucas/duplicity/swift-multibackend-bug

  - Fix a bug when swift backend is used in a multibackend configuration.

* Merged in lp:~duplicity-team/duplicity/po-updates

New in v0.7.12 (2017/03/21)

---------------------------

* Fixed bug #1623342 with patch supplied by Daniel Jakots

* Fixed bug #1658283 "Duplicity 0.7.11 broken with GnuPG 2.0"

  - Made gpg version check more robust than just major version

  - Now use --pinentry-mode=loopback on gpg 2.1 and greater

  - Removed check for non-Linux systems, a false problem

* Merged in lp:~matthew-t-bentley/duplicity/duplicity

  - Sets a user agent. Backblaze asked for this in case there are errors that originate

    from the Duplicity B2 backend

  - Only retrieves a new upload URL when the current one expires, to bring it in line

    with their best practices for integrations: https://www.backblaze.com/b2/docs/integration_checklist.html

* Add detail about import exceptions in onedrivebackend.py

* Fixed bug #1657916 with patch supplied by Daniel Harvey

  - B2 provider cannot handle two backups in the same bucket

* Fixed bug #1603704 with patch supplied by Maciej Bliziński

  - Crash with UnicodeEncodeError

* Some fixes to gpg.py to handle gpg1 & gpg2 & gpg2.1 commandline issues

  - --gpg-agent is optional on gpg1, but on gpg2 it is used automatically

  - --pinentry-mode is not a valid opt until gpg2.1, so condition on that

* Fixed bug #1367675 - IMAP Backend does not work with Yahoo server

  - added the split() as needed in 'nums=list[0].strip().split(" ")'

  - the other fixes mentioned in the bug report comments were already done

* Fixed bug #1671852 - Code regression caused by revision 1108

  - change util.uexc() back to bare uexc()

* Fixed bug #1668750 - Don't mask backend errors

  - added exception prints to module import errors

New in v0.7.11 (2016/12/31)

---------------------------

* Fixed bugs #815510 and #1615480

  - Changed default --volsize to 200MB

* Merged in lp:~mstoll-de/duplicity/duplicity

  - Backblaze announced a new domain for the b2 api

* Merged in lp:~aaron-whitehouse/duplicity/bug_1620085_exclude-if-present-locked-folder

  - Fixes Bug #1620085: --exclude-if-present gives OSError looking for tag in locked folders

* Fixed bug #1623342 with patch from Daniel Jakots

  - failing test on OpenBSD because tar/gtar not found

* Merged in lp:~mwilck/duplicity/duplicity

  - GPG: enable truly non-interactive operation with gpg2

  - This patch fixes the IMO unexpected behavior that, when using GnuPG2, a pass phrase dialog always pops up for

    saving backups. This is particularly annoying when trying to do unattended / fully automatic backups.

* Fixed bug #1621194 with code from Tornhoof

  - Do backup to google drive working without a service account

* Fixed bug #1642098 - does not create PAR2 archives when '--par2-options' is used

  - Missing space between par2-options plus default options

* Fix bug using 40-char sign keys, from Richard McGraw on mail list

  - Remove truncation of argument and adjust comments

* Merged in lp:~dernils/duplicity/robust-dropbox-backend

  - Added new command line option --backend-retry-delay

    that allows to determine the time that duplicity sleeps

    before retrying after an error has occured.

  - Added some robustness to dpbxbackend.py that ensures re-authentication

    happens in case that a socket is changed (e.g. due to a forced reconnect

    of a dynamic internet connection).

* Merged in lp:~ed.so/duplicity/manpage.fixes

  - Fix html output via rman on the website

* Merged in lp:~horgh/duplicity/copy-symlink-targets-721599

  - Add --copy-links to copy symlink contents, not just the link itself.

* Merged in lp:~aaron-whitehouse/duplicity/Bug_1624725_files_within_folder_slash

  - Fixed Bug #1624725, so that an include glob ending in "/" now includes folder contents (for globs with

    and without special characters). This preserves the behaviour that an expression ending in "/" only

    matches a folder, but now the contents of any matching folder is included.

* Fix problem with gpg2 in yakety and zesty

* Fix Bug #1642813 with patch from Ravi

  - If stat() returns None, don't attempt to set perms.

* Merged in lp:~breunigs/duplicity/amazondrive3

  - As reported on the mailinglist, if a space is entered while duplicity asks for the URL, it fails.

    Since all important spaces are URL encoded anyway, this should be fine even if there are spaces in

    the URL at all. I also patched it in the onedrive backend, because it must have similar issues.

* Prep for 0.7.11

New in v0.7.10 (2016/08/20)

---------------------------

* Merged in lp:~mwilck/duplicity/0.7-series

  - Allow symlink to have optional trailing slash during verify.

* Merged in lp:~aaron-whitehouse/duplicity/07-fix_deja_dup_error_on_locked_files

  - Revert log.Error to log.Warn, as it was prior to the merge in rev 1224,

    as this was affecting other applications (e.g. deja dup; Bug #1605939).

* Merged in lp:~duplicity-team/duplicity/po-updates

  - bug introduced in improper fix of bug #1568677

  - gotta love those inconsistent APIs

* Fixed bug #1571134 incompatible with python-oauth2client version 2.x

  - clean up some odd error messages

  - move Pep8 ignores to tox.ini

  - supply correct path for pydevd under Mac

  - fix some tests to run under Linux and Mac

* Partial fix for bug #1529606 - shell code injection in lftpbackend

  - adjusted help text and man page to reflect the change

* Undo changes to test_restart.py.  GNU tar is needed.

* Fix minor pep8 nit in collections.py

  fixes bug #1541314

* Fixed a patching error in ssh_pexpect_backend.py

* Merged in lp:~fpytloun/duplicity/webdav-gssapi-fix

  - Make kerberos optional for webdav backend

* Merged in lp:~harningt/duplicity/multibackend-mirror

  - This changeset addresses multibackend handling to permit a

    mirroring option in addition to its "stripe" mode to make it

    a redundancy tool vs space-expansion tool. To do this without

    changing the configuration too much, I used the query string

    that would generally go unused for files to specify behavior

    that applies to all items inside the configuration file.

* Added acdclibackend.py from Stefan Breunig and Malay Shah

  - renamed from amazoncloudbackend to stress use of acd_cli

* Fixed some 2to3 and Pep8 issues that had crept in

* Backed out changes made by patching for bug #1541314.  These

  patches should not have been applied to the 0.7 series.

* Merged in lp:~rye/duplicity/mediafire

  - Backend for https://www.mediafire.com

  - Requires https://pypi.python.org/pypi/mediafire/ installed.

* Reverted changes made in rev 1164 w.r.t. getting the source from

  VCS rather than local directory.  Fixes bug #1548080.

* More fixes to dist/makedist to make it more OS agnostic.

* Merged in lp:~ed.so/duplicity/webdav.lftp.ssl-overhaul

    duplicity.1, commandline.py, globals.py

      in case it contains special chars (eg. @ or space)

    lftpbackend.py

    - quote _all_ cmd line params

    - added missing lftp+ftpes protocol

      (using system certs eg. in /etc/ssl/certs)

    - added ssl_cacert_path support for python 2.7.9+

    - gettext wrapped all log messages

    - minor refinements

* Applied patch from Dmitry Nezhevenko to upgrade dropbox backend:

  - update to SDK v2

  - use chunked upload

* Merged in lp:~aaron-whitehouse/duplicity/improve_present_get_sf_man_page

  - Improve man page entry for --exclude-if-present

* Merged in lp:~aaron-whitehouse/duplicity/split_glob_matching_from_select

  - Move glob matching code out of selection.py's Select function and

    into globmatch.py.

* Fix bug reported on the mailing list from Mark Grandi (assertion error

  while backing up).  In file_naming.parse() the filename was being lower

  cased prior to parsing.  If you had used a prefix with mixed case, we

  were writing the file properly, but could not find it in the backend.

* Merged in lp:~duplicity-team/duplicity/po-updates

New in v0.7.06 (2015/12/07)

---------------------------

* Merged in lp:~mnjul/duplicity/s3-infreq-access

  - This adds support for AWS S3's newly announced Infrequent Access

    storage class and is intended to implement Blueprint:

    https://blueprints.launchpad.net/duplicity/+spec/aws-s3-std-ia-class .

  - A new command line option, --s3-use-ia, is added, and boto backend

    will automatically use the correct storage class value depending on

    whether --s3-use-rrs and --s3-use-ia is set. Command line parser will

    prompt error if both --s3-use-ia and --s3-use-rrs are used together,

    as they conflict with each other.

  - The manpage has been updated giving a short explanation on the new

    option. Its wording derives from Amazon's official announcement:

    https://aws.amazon.com/about-aws/whats-new/2015/09/announcing-new-\

    amazon-s3-storage-class-and-lower-glacier-prices/

* The ptyprocess module no longer supports Python 2.6, so fix tox.ini to

  use an older version.  Make explicit environs for all tests.

* Upgrade to newest version of pep8 and pylint.   Add three ignores

  to test_pep8 and one to test_pylint to get the rest to pass.  They

* Applied patch from Alexander Zangerl to update to changes in lockfile

  API 0.9 and later.  Updated README to notify users.

* Modded tox.ini to use the latest lockfile.

* Merged in lp:~ed.so/duplicity/setup.shebang

  - Having the python interpreter searched in the PATH is much more

    flexible than the /usr/bin/python inserted into our scripts shebang

    by setuptools.  This patch prevents that. don't touch my shebang! :)

* Cleanup issues around Launchpad build, mainly lockfile >= 0.9.

* Merged in lp:~michal-s/duplicity/duplicity

  - WindowsAzureMissingResourceError and WindowsAzureConflictError

    changed due to SDK changes.

  are all valid in our case.

* Reversed previous changes to lockfile.  Now it will take any version

  extant in the LP build repository.  (PyPi is not avail in LP build).

* Merged in lp:~ed.so/duplicity/tempfile.tempdir

  - make sure packages using python's tempfile create temp files in

    duplicity's temp dir

* Fixed bug #1511308 - Cannot restore no-encryption, no-compression backup

  - Corrected code to include plain file in write_multivolume()

  - Added PlainWriteFile() to gpg.py

* Merged in lp:~michal-s/duplicity/duplicity

  - Fix azurebackend storage class import

* Merged in lp:~feraudet/duplicity/fix

  - Fix missing SWIFT_ENDPOINT_TYPE env var, bug 1519694.

* Fix bug #1520691 - Shell Code Injection in hsi backend

  - Replace use of os.popen3() with subprocess equivalent.

  - Added code to expand relative program path to full path.

  - Fix hisbackend where it expected a list not a string.

* Merged in lp:~noizyland/duplicity/azurebackend-fixes

  - Support new version of Azure Storage SDK

  - Refactor _list method to support containers with >5000 blobs

* Merged in lp:~matthew-t-bentley/duplicity/b2

  - Adds a backed for BackBlaze's (currently beta) B2 backup service.

  - This adds backends/b2backend.py, modifies log.py to add an

    error code and modifies commandline.py to add the b2://

    example to the help text.

* Pep8 corrections for recently released code.

* Fixed bug #1260666 universally by splitting the filelist for

  delete before passing to backend.

* Fixed bug #1369243 by adjusting messages to be more readable.

* Fixed bug #1375019 with patch from Eric Bavier (home to tmp).

New in v0.7.05 (2015/09/15)

---------------------------

* Merged in lp:~aaron-whitehouse/duplicity/fix_patch_error

  - Change use of mock.patch in unit tests to accommodate the obsolete

    version of python-mock on the build server.

* Fixed Bug 1476019 S3 storage bucket not being automatically created

  with patch from abeverley

* Merged in lp:~aaron-whitehouse/duplicity/launchpad_tox_profile

  - Add tox testing profile that mimics the packages installed on the

    Launchpad build server, to reduce the likelihood of tests passing

    our test suite, but failing on the build server (e.g. because of

    the out-of-date mock version).

* Merged in lp:~aaron-whitehouse/duplicity/disable_code_tests_for_lpbuildd

  - Set RUN_CODE_TESTS to 0 for lpbuildd tox profile, reflecting its value

    on the Launchpad build server (and therefore skipping PEP8, 2to3 and

    pylint). More accurately reflects the system we are mimicking and saves

    approximately 1 minute per test run.

* Fixed Bug 1438170 duplicity crashes on resume when using gpg-agent with

  patch from Artur Bodera (abodera).  Applied the same patch to incremental

  resumes as well.

* Merged in lp:~w.baranowski/duplicity/selection_debug

  - This little patch logs debug messages concerning path selection process,

    and so allows users to debug their include/exclude configuration.

* Merged in lp:~germar/duplicity/par2removefix

  - After reorganisation in revision 981 and the fix for bug #1406173 the

    par2backend does not remove .par2 files anymore when removing

    duplicity-*.gpg files.

  - This banch adds an unfiltered_list() method which is used in

    delete() and delete_list()

* Updated man pages to reflect more contributors.

* Fix bug #1493573.  Correct option typo in man page.

* Fix bug #1494228 CygWin: TypeError: basis_file must be a (true) file

  - The problem that caused the change to tempfile.TemporaryFile was due

    to the fact that os.tmpfile always creates its file in the system

    temp directory, not in the directory specified.  The fix applied was

    to use os.tmpfile in cygwin/windows and tempfile.TemporaryFile in all

    the rest.  This means that cygwin is now broken with respect to temp

    file placement of this one file (deleted automatically on close).

* Merged in lp:~bmerry/duplicity/pydrive-id-cache

  - This fixes the issue a number of users (including myself) have been

    having with duplicity creating files with duplicate filenames on

    Google Drive. It keeps a runtime cache of filename to object ID

    mappings, so that once it has uploaded an object it won't be fooled

    by weakly consistent directory listings.

* Merged in lp:~duplicity-team/duplicity/po-updates

New in v0.7.04 (2015/08/02)

---------------------------

* Merged in lp:~noizyland/duplicity/fix-progress

  - Fixes bug 1264744.  selection.filelist_globbing_get_sfs leaves the

    filelist file object's position at the end of the file. When the

    --progress option is used the filelists need to be read twice. On

    the second read nothing is read from the file because file has

    already been read and the position is EOF.  This patch calls seek(0)

    on the filelist to reset the position to BOF so that subsequent

    read() calls will return data.

* Added pylint ignore error in webdavbackend.py.

* Merged in lp:~bmerry/duplicity/pydrive-regular

  - This implements the proposal made by somebody else

    (http://lists.gnu.org/archive/html/duplicity-talk/2015-02/msg00037.html)

    to allow the pydrive backend to work with a normal drive account instead

    of a service account. It seems to be working for me: I was able to migrate

    seamlessly from the gdocs backend. It's set up so that a service account

    can still be used, depending on which environment variable is set.

    The man page is updated to describe how to use the new functionality.

* Merged in lp:~ed.so/duplicity/gdocs.pydrive

  - make pydrive new gdocs default backend

  - keep gdata backend as gdata+gdocs://

* Merged in lp:~raymii/duplicity/fix-swiftbackend-max-10000-files-in-list

  - Swiftclient by default returns at max 10000 files. By adding

    full_listing=True we make sure all objects are returned.

    Ref: https://lists.nongnu.org/archive/html/duplicity-talk/2015-05/msg00060.html

    and http://docs.openstack.org/developer/python-swiftclient/swiftclient.html#swiftclient.client.get_container

* Fix a couple of PEP8 glitches.

* Fixed bug 791794 - description of --gpg-options is misleading, Simply

  needed to add the '--' before the options as in "--opt1 --opt2=parm".

* Fixed bug 1465335 - pydrive still use files in trash can - with patch

  from Kuang-che Wu to ignore trashed files.

* Fixed bug 1452263 - par2 option not working on small processors - with patch

  from Kuang-che Wu to ignore default 30 second timeout.

* Fixed bug 1466160 - pydrive backend is slow to remove old backup set - with

  patch from Kuang-che Wu to implement _delete_list().

* Fixed bug 1466582 - reduce unnecessary syscall with --exclude-if-present - with

  patch from Kuang-che Wu to make sure resulting path is a directory.

* Merged in lp:~ed.so/duplicity/gpg.binary

  - new parameter --gpg-binary allows user to point to a different gpg binary,

    not necessarily in path

* Merged in lp:~aaron-whitehouse/duplicity/fix_POTFILES.in_and_run-tests

  - Fixed two filename references in po/POTFILES.in, a mistake which crept in in

    rev 1093 and caused testing/run-tests to fail with "IndexError: list index

    out of range".

* Merged in lp:~aaron-whitehouse/duplicity/reactivate_progress_test

  - Re-enable the test of the --progress option (test_exclude_filelist_progress_option),

    which was marked as an expected failure. The issue causing this test to fail was

    fixed in revision 1095 and the test now passes.

* Fixed bug 1471348 Multi back-end doesn't work with hubiC

  - added init of appropriate superclass in both cases.

* Fixed bug 1471348 Multi back-end doesn't work with hubiC (again)

  - hubiC should reach up to duplicity.backend.__init__

* Merged in lp:~aaron-whitehouse/duplicity/bug_884371

  - Fixed Bug #884371 - Stopped an exclude glob trumping an earlier scan glob, but also

    ensured that an exclude glob is not trumped by a later include. This fix is important,

    as without it files that are specified to be included are not being backed up as expected.

  - Fixed Bug #932482 - a trailing slash at the end of globs no longer prevents them working

    as expected.

* Merged in lp:~aaron-whitehouse/duplicity/reenable_tests

  - Re-enable unit.test_selection tests that had been temporarily commented out.

* Merged in lp:~aaron-whitehouse/duplicity/trailing_slash_match_dirs

  - Made globs with trailing slashes only match directories, not files, fixing Bug #1479545.

* Merged in lp:~aaron-whitehouse/duplicity/improve_tox_and_python2-6_testing

  - Testing improvements, particularly in relation to testing against Python version 2.6:

    * tox.ini fixed so that it is possible to run individual tests against both Python 2.6 and 2.7;

    * updated test_code.py to use unittest2 for Python versions < 2.7 (instead of failing);

    * ./run-tests now correctly runs all tests against both Python 2.6 and 2.7; and

    * improved testing directions in README-REPO.

* Merged in lp:~dag-stenstad/duplicity/swift_authversion_3_support

  - Added support for Openstack Identity v3 in the Swift backend.

* Merged in lp:~aaron-whitehouse/duplicity/fix_2to3_issues

  - Fixed 2to3 issues. Updated README-REPO with more test information. Updated pylint and

    test_diff2 descriptions to make it clear these require packages to be installed on the

    sytem to pass. All tests pass on Python 2.6 and Python 2.7 as at this revision.

New in v0.7.03 (2015/05/11)

---------------------------

* Merged in lp:~aaron-whitehouse/duplicity/filelist_combine

  - Merged globbing and non-globbing filelists to use the same code path

    and all accept globbing characters. Added deprecation warning to the

    --exclude-globbing-filelist and include-globbing-filelist options in

    commandline.py and hid them from help output. Updated the manual

    (and unit tests) accordingly.

  - Note that this does trigger a change in behaviour for duplicity.

    Previously, include patterns in include-filelist did not match files

    in a directory that was included, so /usr/local in an include file

    would not have matched /usr/local/doc. Now, this folder would be

    included, as would occur if --include or the old

    --include-globbing-filelist was used. Additional lines will therefore

    need to be added to filelists to unambiguously exclude unwanted

    subfolders, if this is intended.

  - Mark --include-filelist-stdin and --exclude-fielist-stdin for

    deprecation and hide from --help output.

* Fix bug 1432999 with hint from Antoine Afalo.

  - '/'s at end of destination cause problems with onedrivebackend.

* Fix bug 1434702 with help from Robin Nehls

  - incorrect response BackendException while downloading signatures file.

* Fix bug 1437789 with patch from pdf

  - par2backend.py incorrect syntax in get()

* Merge in lp:~stynor/duplicity/multi-backend

  - A new backend that allows use of more than one backend stores (e.g. to

    combine the available space from more than one cloud provider to make

    a larger store available to duplicity).

* Move requirements section lower in manpage.

* Merge in lp:~cemsbr/duplicity/duplicity

  - Fix bug 1432229 in Copy.com backend:

    Reply header has no content-type for JSON detection. Now, we also check

    whether the content starts with '{'.

* Fixed bug 1444404 with patch from Samu Nuutamo

  - rdiffdir patch crashes if a regular file is changed to a non-regular

    file (symlink, fifo, ...)

* Fixed bug 1448249 and bug 1449151 thanks to David Coppit.

  - When patching, close base file before renaming

  - Enable --ignore-errors flag in rdiffdir

* Added ability to get single file status from collection-status with

  patch from jitao (bug 1044715), like so:

  $ duplicity collection-status --file-changed c1 file://./foo

* Merge in lp:~sjakthol/duplicity/onedrive-error-message

  - Add proper error message for OneDrive backend when python-requests or

    python-requests-oauthlib is not installed (bug 1453355).

New in v0.7.02 (2015/03/10)

---------------------------

* Merged in lp:~vincegt/duplicity/swift_regionname

  - Fixes bug #1376628

  - Add mapping of SWIFT_REGIONNAME to select region inside SWIFT when a

    provider proposes more than one region.

* Merged in lp:~aaron-whitehouse/duplicity/progress_option_error

  - Added test_exclude_globbing_filelist_progress_option into

    functional/test_selection.py, which shows the error reported in

    Bug #1264744 - that the --exclude-globbing-filelist does not backup

    the correct files if the --progress option is used. Test is marked as

    an expected failure so as not to cause the test suite to fail.

* Merged in lp:~noizyland/duplicity/fix_azurebackend_container_names

  - Azure Backend examples have underscores in the container names.  These

    are not valid Azure container names.  The underscores have been replaced

    with hypens and a note about valid container names added to the man page.

  - Also corrects a problem where Azure Exceptions were returing unicode

    strings that were not being handled correctly.

* Merged in lp:~user3942934/duplicity/pydrive

  - Currently duplicity uses gdocs backend for Google Drive backups.

    gdocs uses deprecated API and don't allow backups for managed Google

    accounts.  (see https://bugs.launchpad.net/duplicity/+bug/1315684)

  - Added pydrive backend that solves both of those problems. Published

    also on https://github.com/westerngateguard/duplicity-pydrive-backend.

* Fixed some tabs/spaces problems that were causing install failures.

* Fixed variable typo in commandline.py that was causing build fails.

* Merged in lp:~duplicity-team/duplicity/po-updates

* Remove 'gs' and 's3+http' from uses_netloc[].  Fixes Bug 1411803.

* Fixed bug # 1414418

  - Aligned commandline.py options and help display contents.

  - Aligned commandline.py options and manpage contents.

* Changed --s3_multipart_max_timeout to --s3-multipart-max-timeout to be

  consistent with commandline option naming conventions.

* Applied patch from Adam Reichold to fix bug # 1413792.

* Merged in lp:~angusgr/duplicity/exclude-older-than

  - Add "--exclude-older-than" commandline option, that allows you to only

    back up files with a modification date newer than a particular threshold.

* Merged in lp:~aaron-whitehouse/duplicity/bug_884371_asterisks_in_includes

  - Added tests to unit/test_selection.py and funtional/test_selection.py

    to show the behaviour reported in Bug #884371, i.e. that selection is

    incorrect when there is a * or ** on an include line of a filelist or

    commandline --include.

* Merged in lp:~aaron-whitehouse/duplicity/bug_932482_trailing_slashes_and_wildcards_error

  - Added functional and unit tests to show Bug #932482 - that selection does

    not work correctly when excludes (in a filelist or in a commandline option)

    contain both a single or double asterisk and a trailing slash.

* Misc fixes for the following PEP8 issues:

  - E111, E121, E122, E124, E125, E126, E127, E128, E201, E202, E203,

    E231, E241, E251, E261, E262, E271, E272, E301, E302, E303, E401,

    E502, E701, E702, E703, E711, E721, W291, W292, W293, W391

  - to run pep8 on duplicity use 'pep8 --ignore=E501'

  - see http://pep8.readthedocs.org

* Fixes for 2to3 issues

* Fix spelling error in manpage, bug 1419314.

* Fix _librsyncmodule.c compilation, bug 1416344, thanks to Kari Hautio.

* Really fix bug 1416344 based on comment #5 by Roman Tereshonkov.

* Fix for --pydevd debug environment and location under Eclipse.

* Fix for bug where scp was actually working as scp and not working with

  rsync.net because of using extraneous test command in restricted shell.

  Was trying "test -d 'foo' || mkdir -p 'foo'", now only "mkdir -p foo".

* remove extraneous string format arg in previous scp fix.

New in v0.7.01 (2015/01/11)

---------------------------

Enhancements:

* Undid move of testing/test_code.py.  Instead I fixed it

  so that it would not run during PPA build.  It now needs

  the setting RUN_CODE_TESTS=1 in the environment which is

  supplied in the tox.ini file.

* Moved testing/test_code.py to testing/manual/code_test.py

  so PPA builds would succeed.  Should be moved back later.

* Remove valid_extension() check from file_naming.py.  It was

  causing failed tests for short filenames.  Thanks edso.

* Partial fix for PPA build failures, new backend name.

* Merged in lp:~ed.so/duplicity/fix.dpbx.import

  - fix dpbx import error import lazily

* Merged in lp:~hooloovoo/duplicity/fix-typo-in-test-description

  - Fixed spelling mistake/typo in a description of a test.

* Merged in lp:~mterry/duplicity/missing-unicode-escape

  - Convert restore_dir to unicode before printing.

* Merged in lp:~ed.so/duplicity/lftp.ncftp.and.prefixes

  - retire --ssh-backend, --use-scp parameters

  - introduce scheme prefixes for alternative backend selection

    e.g. ncftp+ftp://, see manpage

  - scp is now selected via scheme e.g. scp://

  - added lftp fish, webdav(s), sftp support

* Merged in lp:~mterry/duplicity/code-nits

  - Fix some pylint/pep8 nits that prevented the test_code.py test from passing.

* Merged in lp:~mterry/duplicity/debian-dir

  - Add a debian/ directory to make it easier to manage the PPAs for duplicity.

* In webdavbackend.py:

  - Fixed bug 1396106 with change by Tim Ruffing, mispelled member.

  - Added missing 'self.' before member in error message.

* Merged in lp:~adrien-delhorme/duplicity/hubic

  - Add Hubic support through pyrax and a custom pyrax_identity module.

* Fixed bug 1385599 with changes by Yannick Molin. SSL settings are now

  conditioned on protocol ftp or ftps.

* Partial fix of bug 1236248 with changes by az, manpage warning about

  --extra-clean, however, recovery with missing sig files is broken.

* Fixed bug 1255453 with changes by Gaudenz Steinlin, report backend import

  results, both normal and failed, at INFO log level.

* Manually merged in lp:~m4ktub/duplicity/0.6-reliability

  - Per fix proposed in Bug #1395341.

* Modded .bzrignore to ignore *.egg test dependencies, normalized, sorted.

* Merged in lp:~ed.so/duplicity/paramiko.identyfile

  - fix identity file parsing of --ssh-options for paramiko

  - manpage fixes

* Source formatted, using PyDev, all source files to fix some easily fixed

  PEP8 issues. Use ignore space when comparing against previous versions.

* Merge in lp:~andol/duplicity/signkeyformat

  - Allow --sign-key to use short format, long format alt. full fingerprint.

* Merge in lp:~hooloovoo/duplicity/verify-not-check-source

  - Tests to validate that duplicity does not check filesystem source during

    verify unless --compare-data is specified

* Merge in lp:~ed.so/duplicity/move_netloc

  - move netloc usage definitions into respective backends

  - fix "[Question #259173]: rsync backend fails"

    https://answers.launchpad.net/duplicity/+question/259173

* Make ssh an unsupported backend scheme

* Temporarily disable RsyncBackendTest and test_verify_changed_source_file

* Merge in lp:~hooloovoo/duplicity/test-verify-improvements

  - Fix up test_verify, which was a bit of a mess:

  - Simplify test_verify.py to just do a simple backup and verify on a

    single file in each test.

  - Modify tests to correctly use --compare-data option.

  - Add tests for when the source files have atime/mtime manipulated.

* Fix duplicity verify to ignore the file system when globals.compare_data is

  False.  This means that verify only validates the viability of the backup

  itself unless --compare-data is specified.

* Reenable test_verify_changed_source_file test

* Merged in lp:~hooloovoo/duplicity/add-additional-verify-tests-for-corrupted-archives

  - Add tests to test_verify.py to test that verify fails if the archive

    file is corrupted. Changed file objects to use the with keyword to ensure

    that the file is properly closed.

  - Small edit to find statement in verify_test.sh to make it work as

    expected (enclose string in quotes).

* Merged in lp:~hooloovoo/duplicity/add-else-to-badupload-try-except

  - Badupload test previously did not have an else in the try-except. The

    test passed if the except was triggered, but would also pass if the

    test did not trigger an error at all.

* Fixed bug 1406173 by applying patch supplied in report

  - Ignore .par2 files in remote file list

* Removed redundant shell test testing/verify_test.sh

* Misc fixes for the following PEP8 issues:

   - E211, E221, E222, E225, E226, E228

   - see http://pep8.readthedocs.org

* Fixed bug 1278529 by applying patch supplied in report

  - Use get_bucket() rather than lookup() on S3 to get proper error msg.

* Merged in lp:~stapelberg+ubuntu/duplicity/add-onedrive-backend

  - Add a Microsoft OneDrive backend

* Merged in lp:~hooloovoo/duplicity/filelist_select_bug_1408411

  - Adds functional test cases that fail because of Bug #1408411 (commented

    out), to assist in fixing that bug.

* Merged in lp:~hooloovoo/duplicity/process_filelists_for_spaces_etc

  - Process filelists to remove imperfections such as blank lines, comments

    and leading/trailing whitespace. Also correctly processes quoted folders

    containing spaces in their names. Extensive unit and functional tests to

    test these changes (and selection more generally).

  - The branch does add an additional folder to testfiles.tar.gz called

    select2. This included a folder with a trailing space, to test the quote

    test. The subfolders also have clearer names than in the "select" folder

    (eg "1sub2sub3") which makes it easier to keep track of issues in tests.

* Merged in lp:~9-sa/duplicity/FixBug1408289

  - Fix bug #1408289

  - Wrong attribute name prevented raise of client exception, working now

* Merged in lp:~noizyland/duplicity/azurebackend

  - Add backend for Azure Blob Storage Service

New in v0.7.00 (2014/10/23)

---------------------------

Enhancements:

* Adjust unit tests to expect single FTP backend

* Merged in lp:~moritzm/duplicity/duplicity

  - Use lftp for both FTP and FTPS

* Merged in lp:~ed.so/duplicity/0.7-dpbx.importfix

  - fix this showstopper with the dropbox backend

    "NameError: global name 'rest' is not defined"

* Merged in lp:~jflaker/duplicity/BugFix1325215

  - The reference to "--progress_rate" in the man page as a parameter is

    incorrect. Should be "--progress-rate".

* Merged in lp:~hooloovoo/duplicity/updated-README-REPO

  - Changes to README-REPO to reflect the restructuring of the directories.

* Fixed bug 1375304 with patch supplied by Aleksandar Ivanovic

* Merged in lp:~ed.so/duplicity/webdav200fix-0.7

  - webdav backend fix "BackendException: Bad status code 200 reason OK. " when

    restarting an interrupted backup and overwriting partially uploaded volumes.

* Merged in lp:~mterry/duplicity/require-2.6

  - Require at least Python 2.6.

  - Our code base already requires 2.6, because 2.6-isms have crept in. Usually

    because we or a contributor didn't think to test with 2.4. And frankly,

    I'm not even sure how to test with 2.4 on a modern system.

* Merged in lp:~mterry/duplicity/drop-pexpect

  - Drop our local copy of pexpect in favor of a system version.

  - It's only used by the pexpect ssh backend (and if you're opting into that,

    you probably can expect that you will need pexpect) and the tests.

  - I've done a quick smoketest (backed up and restored using

    --ssh-backend=pexpect) and it seemed to work fine with a modern version

    of pexpect.

* Merged in lp:~mterry/duplicity/2.6isms

  - Here's a whole stack of minor syntax modernizations that will become

    necessary in python3. They all work in python2.6.

  - I've added a new test to keep us honest and prevent backsliding on these

    modernizations. It runs 2to3 and will fail the test if 2to3 finds anything

    that needs fixing (with a specific set of exceptions carved out).

  - This branch has most of the easy 2to3 fixes, the ones with obvious and

    safe syntax changes.

  - We could just let 2to3 do them for us, but ideally we use 2to3 as little

    as possible, since it doesn't always know how to solve a given problem.

    I will propose a branch later that actually does use 2to3 to generate

    python3 versions of duplicity if they are requested. But this is a first

    step to clean up the code base.

* Merged in lp:~mterry/duplicity/drop-static

  - Drop static.py.

  - This is some of the oldest code in duplicity! A bzr blame says it is

    unmodified (except for whitespace / comment changes) since revision 1.

  - But it's not needed anymore. Not really even since we updated to python2.4,

    which introduced the @staticmethod decorator. So this branch drops it and

    its test file.

* Merged in lp:~mterry/duplicity/py3-map-filter

  - In py3, map and filter return iterable objects, not lists. So in each case

    we use them, I've either imported the future version or switched to a list

    comprehension if we really wanted a list.

* Merged in lp:~mterry/duplicity/backend-unification

  - Reorganize and simplify backend code.  Specifically:

    - Formalize the expected API between backends and duplicity.  See the new

      file duplicity/backends/README for the instructions I've given authors.

    - Add some tests for our backend wrapper class as well as some tests for

      individual backends.  For several backends that have some commands do all

      the heavy lifting (hsi, tahoe, ftp), I've added fake little mock commands

      so that we can test them locally.  This doesn't truly test our integration

      with those commands, but at least lets us test the backend glue code.

    - Removed a lot of duplicate and unused code which backends were using (or

      not using).  This branch drops 700 lines of code (~20%)

      in duplicity/backends!

    - Simplified expectations of backends.  Our wrapper code now does all the

      retrying, and all the exception handling.  Backends can 'fire and forget'

      trusting our wrappers to give the user a reasonable error message.

      Obviously, backends can also add more details and make nicer error

      messages.  But they don't *have* to.

    - Separate out the backend classes from our wrapper class.  Now there is no

      possibility of namespace collision.  All our API methods use one

      underscore.  Anything else (zero or two underscores) are for the backend

      class's use.

    - Added the concept of a 'backend prefix' which is used by par2 and gio

      backends to provide generic support for "schema+" in urls -- like par2+

      or gio+.  I've since marked the '--gio' flag as deprecated, in favor of

      'gio+'.  Now you can even nest such backends like

      par2+gio+file://blah/blah.

    - The switch to control which cloudfiles backend had a typo.  I fixed this,
