<p>Apache Subversion 1.14 is a superset of all previous Subversion
releases, and is as of the time of its release considered the current
"best" release. Any feature or bugfix in 1.0.x through 1.13.x is also
in 1.14, but 1.14 contains features and bugfixes not present in any
earlier release.</p>
<p>Because 1.14 is the next LTS release following 1.10, these release
notes describe major changes since 1.10, including changes released in
1.11.x through 1.13.x.</p>
<p>This page describes only major changes. For a complete list of
changes, see the 1.14 section of the <a
href="https://svn.apache.org/repos/asf/subversion/trunk/CHANGES" >CHANGES</a>
file.</p>

<div class="h2" id="compatibility">
<h2>Compatibility Concerns
<a class="sectionlink" href="#compatibility"
title="Link to this section">¶</a>
</h2>
<p>Older clients and servers interoperate transparently with 1.14
servers and clients. However, some of the new 1.14 features may not be
available unless both client and server are the latest version. There are
also cases where a new feature will work but will run less efficiently if
the client is new and the server old.</p>
<p>There is <strong>no need</strong> to <a href="http://svnbook.red-bean.com/en/1.8/svn.reposadmin.maint.html#svn.reposadmin.maint.migrate.svnadmin"
>dump and reload</a> your repositories.
Subversion 1.14 servers can read and write to repositories created by
earlier versions. To upgrade an existing server installation, just install the
newest libraries and binaries on top of the older ones.</p>
<p>Subversion 1.14 maintains API/ABI compatibility with earlier
releases, by only adding new functions, never removing old ones. A
program written to any previous 1.x API can both compile
and run using 1.14 libraries. However, a program written for 1.14
cannot necessarily compile or run against older libraries.</p>
<p>There may be limited cases where the behavior of old APIs has been
slightly modified from previous releases. These are cases where edge cases
of the functionality has been deemed buggy, and therefore improved or removed.
Please consult the
<a href="https://svn.apache.org/repos/asf/subversion/trunk/notes/api-errata/1.14/"
>API errata</a> for more detailed information on what these APIs are
and what impact these changes may have.</p>

<h3>Upgrading the Working Copy
<a class="sectionlink" href="#wc-upgrade"
title="Link to this section">¶</a>
</h3>
<p>Subversion 1.14 uses the same working copy format as Subversion 1.8 through 1.13.</p>
<p>Before using Subversion 1.14 with an existing Subversion 1.7 or older
working copy, users will be required to run the <tt>svn upgrade</tt> command
to upgrade working copy metadata to the new format. This command may take a
while in some cases, and for some users, it may be more practical to simply
checkout a new working copy.</p>
<p><strong>Note:</strong> Subversion 1.14 cannot upgrade working copies that
a 1.6 client would have refused to operate upon before an <tt>svn cleanup</tt>
was run (with a 1.6 client). In other words, before upgrading to 1.8 or newer,
a 1.6
or older client must be used to run <tt>svn cleanup</tt> on all 1.6 or older
working copies that require cleanup. Likewise, Subversion 1.14 cannot upgrade
corrupt working copies. Unfixable problems can arise from missing or corrupt
meta-data inside <tt>.svn</tt> directories. Such damage to the working copy
is permanent, and cannot be fixed even if <tt>svn cleanup</tt> is run prior
to the upgrade.</p>
<p>If your working copy does not upgrade cleanly, please check out a new one.

<h3>Changes to Experimental Shelving Feature
<a class="sectionlink" href="#compatibility-shelving"
title="Link to this section">¶</a>
</h3>
<p>Since 1.10, Subversion provides an experimental "Shelving" feature aimed
at addressing <a href="https://issues.apache.org/jira/browse/SVN-3625">issue
#3625</a>. There is no promise of backward compatibility for features
designated "experimental."</p>
<p>Shelving in 1.14 has changed significantly since 1.10 and is incompatible
with shelves created by 1.10. See <a href="#shelving">Shelving and
Checkpointing (experimental)</a> for the major changes and differences in
commands. See its subsection, <a href="#shelving-transition">Upgrading
1.10–1.13 shelves to 1.14</a> to learn how to recover 1.10 shelves in
an existing working copy.</p>

<h3>Miscellaneous Compatibility Notes
<a class="sectionlink" href="#compat-misc"
title="Link to this section">¶</a>
</h3>
<p>There are some additional specific areas where changes made in this
release might necessitate further adjustment by administrators or
users. We'll cover those in this section.</p>
<div class="h4" id="compat-misc-authz">
<h4>Path-based authorization compatibility
<a class="sectionlink" href="#compat-misc-authz"
title="Link to this section">¶</a>
</h4>
<p>A fix for <a href="https://issues.apache.org/jira/browse/SVN-4762?issueNumber=4762"
>Issue #4762</a> may change the way path-based authorization rules are applied
in some circumstances. See <a href="http://svn.apache.org/r1882326">r1882326</a>.</p>
<p>Background: Subversion 1.10 introduced a new implementation of path-based
authorization (authz) to deliver wildcard support and improved performance
over that of Subversion 1.9 and earlier. From Subversion 1.10 through 1.14.0,
the new implementation did not correctly combine global rules with repository
rules: if a global rule and a per-repository rule were both present for a
path, the global rule would be ignored and the per-repository rule would
apply by itself. As a result, from Subversion 1.10 through 1.14.0, it was not
possible to override per-path access rules for specific users (or groups) at
the global level. Administrators whose authz rules rely on this incorrect
behavior may need to adjust their rules accordingly.
</p>
<p>This issue is fixed in 1.14.1, making it possible once again to
override per-path access rules for specific users (and groups) at the global level.
Such global rules are overridden by repository-specific rules only if both the
user and the path match the repository-specific rule.</p>
<p>As an example, consider the following rule set:</p>
<pre>
[groups]
company = developer1, developer2, developer3
customer = customer1, customer2
# company can read-write on everything
[/]
@company = rw
[project1:/]
@customer = r
</pre>
<p>
Does <tt>developer1</tt> have <tt>rw</tt> access to <tt>"/trunk"</tt> in <tt>project1</tt>?
</p>
<p>
Subversion servers running 1.10.0 up to 1.10.6 or 1.14.0, without the fix for
<a href="https://issues.apache.org/jira/browse/SVN-4762?issueNumber=4762"
>issue #4762</a>, will only apply the repository-specific part of the rule set:</p>
<pre>
[project1:/]
@customer = r
</pre>
<p>
The answer in this case is that <tt>developer1</tt> has no access at all because the
global rule which grants <tt>rw</tt> access to the <tt>@company</tt> group is ignored.
</p>
<p>
Subversion servers running 1.14.1 or later match the behaviour of
Subversion 1.9, meaning they will apply both the global and the repository-specific
part of the rule set:</p>
<pre>
# company can read-write on everything
[/]
@company = rw
[project1:/]
@customer = r
</pre>
<p>
The answer in this case is that <tt>developer1</tt> has <tt>rw</tt> access
to any path in <tt>project1</tt>.
Global rules are overridden by repository-specific rules only if both the
user (<tt>developer1</tt>) and the path (<tt>"/"</tt>, including child paths
for which no specific rules exist) match the repository-specific rule.
While the repository-specific rule matches <tt>"/trunk"</tt> it does not
match <tt>developer1</tt>, and hence the global rule will be used.

<h3>New <tt>svnadmin build-repcache</tt> command
<a class="sectionlink" href="#svnadmin-build-repcache"
title="Link to this section">¶</a>
</h3>
<p>Representation Sharing (also called rep-sharing) is a data storage
de-duplication feature first introduced in Subversion 1.6. It reduces the disk
size of a repository by storing duplicate data only once. (See <a
href="https://issues.apache.org/jira/browse/SVN-2286">issue #2286</a>.)</p>
<p>This optional feature is enabled by default. It relies on a rep-cache
database, which Subversion automatically maintains with the repository, to
identify duplicate pieces of data.</p>
<p>Over time, some administrators have disabled and/or re-enabled rep-sharing,
which has the effect of excluding from the rep-cache any revisions that were
committed while the feature was disabled.</p>
<p>Subversion 1.14 introduces a new <tt>svnadmin build-repcache</tt>
subcommand, which administrators can use to populate any missing entries in
the rep-cache database for a specified revision range (or all revisions). (See
<a href="http://svn.apache.org/r1875921">r1875921</a>.)</p>
<p>For example, to process revisions 20 through 25, inclusive, and ensure that
their data is known to the rep-cache:</p>
<pre>
$ svnadmin build-repcache /path/to/repo -r20:25
* Processed revision 20.
* Processed revision 21.
* Processed revision 22.
* Processed revision 23.
* Processed revision 24.
* Processed revision 25.
</pre>
<p>If only one revision argument is given, <tt>svnadmin build-repcache</tt>
will process that revision only:</p>
<pre>
$ svnadmin build-repcache /path/to/repo -r20
* Processed revision 20.
</pre>
<p>If no revision argument is given, <tt>svnadmin build-repcache</tt> will
process all revisions.</p>

<h4>Escaping/quoting of pathname arguments to the user-defined editor
<a class="sectionlink" href="#editor-filename-escaping"
title="Link to this section">¶</a>
</h4>
<p>When invoking the user-defined editor, such as during interactive conflict
resolution, Subversion now performs escaping of any special characters in the
pathname of the file to be edited. This corrects a problem that would occur
previously when the file to be edited (and/or the path leading to it)
contained spaces or other special characters. (See
<a href="http://svn.apache.org/r1874057">r1874057</a>,
<a href="http://svn.apache.org/r1874093">r1874093</a>, and
<a href="http://svn.apache.org/r1875230">r1875230</a>.)</p>
<p>Note that escaping is performed only on the pathname argument. As before,
the editor itself is invoked through the shell and the user must properly
quote/escape the command line used to launch it. This is intentional, as it
allows the user to construct a shell command which itself contains command
line arguments. See the related
<a href="https://subversion.apache.org/faq.html#svn-editor">FAQ entry</a> for
more on spaces and/or command line options in the editor path.</p>
<p>The user-defined editor can be specified in the following ways, in this
order of precedence:</p>
<ul>
<li>The <tt>--editor-cmd</tt> command-line option</li>
<li>The <tt>$SVN_EDITOR</tt> environment variable</li>
<li>The <tt>editor-cmd</tt> runtime configuration option</li>
<li>The <tt>$VISUAL</tt> environment variable</li>
<li>The <tt>$EDITOR</tt> environment variable</li>
</ul>
<p>The escaped pathname of the file to be edited is passed to the editor as
its last command line argument.</p>
<p>For example, suppose that <tt>$SVN_EDITOR</tt> is set as follows:</p>
<pre>SVN_EDITOR='vim -N --'
export SVN_EDITOR
</pre>
<p>Furthermore, suppose 'svn up' finds a text conflict in a file called
<tt>foo bar.txt</tt>:</p>
<pre>
$ svn up
Updating '.':
C foo bar.txt
Updated to revision 2.
Summary of conflicts:
Text conflicts: 1
Merge conflict discovered in file 'foo bar.txt'.
Select: (p) Postpone, (df) Show diff, (e) Edit file, (m) Merge,
(s) Show all options: <b>e</b>
</pre>
<p>When Subversion launches the editor, the spaces in <tt>vim -N --</tt> will
<strong>not</strong> be escaped, allowing vim to be invoked with <tt>-N</tt>
and <tt>--</tt> as its first two arguments, but the space in
<tt>foo bar.txt</tt> <strong>will</strong> be escaped.</p>
</div> <!-- editor-filename-escaping -->

<h4>Improvements to the interactive conflict resolver
<a class="sectionlink" href="#conflict-resolver"
title="Link to this section">¶</a>
</h4>
<p>Since its introduction in 1.10, the new interactive conflict resolver has
received various improvements.</p>
<p>Starting in 1.11, the interactive conflict resolver supports more conflict
situations which involve moved files and directories. Specifically, many tree
conflicts which report a "locally missing" item, as a result of an item having
moved on the merge source branch, can now be resolved automatically.</p>
<p>For example, when a file edit is cherry-picked from a branch on which
the edited file has been renamed, the edit will now be applied to the file's
location in the merge target branch, provided it has not been renamed
on that branch as well. For details, see
<a href="https://issues.apache.org/jira/browse/SVN-4694">issue #4694</a>,
"Unresolvable tree conflict when cherrypicking a file-edit after file was
moved on source branch".</p>
<p>Furthermore, since 1.12, the interactive conflict resolver supports some
cases where items were moved to disparate locations. Support for unversioned
items in the working copy has been improved as well. The table below lists
these cases and available resolution options for each.</p>

<p>During <tt>svn update</tt>, the deletion of a directory which contains
unversioned items but is otherwise unmodified no longer causes a tree

in the working copy, for example.</p>
<p>Several bugs have been fixed in the conflict resolver, including:
<ul>
<li><a href="https://issues.apache.org/jira/browse/SVN-4744">Issue #4744</a>
"assertion failed (start_rev > end_rev)"</li>
<li><a href="https://issues.apache.org/jira/browse/SVN-4766">Issue #4766</a>
"resolver adds unrelated moves to move target list"</li>
<li>A problem where the resolver mistakenly
<a href="https://svn.apache.org/r1839662">searched back through
the entire history of the repository</a></li>
<li>A case where text conflicts were created with the incoming changes
theirs) and local changes (mine) swapped within text conflict markers. This
caused unexpected results when the <tt>svn resolve</tt> command was used with
the <tt>--accept theirs</tt> or <tt>--accept mine</tt> options. This is fixed
as of 1.12.</li>

the duration of this support period.</p>
<p>This means that although Subversion 1.14.0 still technically works

if it becomes too difficult to maintain.</p>
<p>If you must continue using Python 2.7, our previous Long Term Support

<h4>Shelving-v2
<a class="sectionlink" href="#shelving-v2"
title="Link to this section">¶</a>
</h4>
<p>Shelving-v2, first introduced in 1.11, improves upon the initial shelving
feature introduced in 1.10. The main improvements and changes are:</p>
<ul>
<li>checkpointing support: a shelf stores multiple versions of a
change; shelving adds a new version to the named shelf; you can
unshelve an older version instead of the newest—see the
<a href="#shelving-checkpointing">commit checkpointing</a> feature</li>
<li>'binary' files (and property values) are fully supported</li>
<li>patch files are no longer used as the storage mechanism;
limitations and bugs due to patch file format are gone, such as
handling svn:mergeinfo properties, binary data, and end-of-line
characters</li>
<li>shelving and unshelving both warn and refuse to run if they detect
states that they cannot handle (e.g. copies or moves)</li>
<li>unshelving applies the changes to the WC using a mechanism similar
to merging, so that changes can be more robustly applied when the
WC has been modified (e.g. updated) since the shelf was saved</li>
</ul>
<p>Shelving-v2 can shelve committable changes to files and properties, except
the following kinds which it does not support:</p>
<ul>
<li>copies and moves</li>
<li>creating and deleting directories</li>
</ul>
<p>Shelves created by Shelving-v2 are stored under
<tt><i><WC></i>/.svn/experimental/shelves/v2</tt>.</p>

<h4>Shelving-v3
<a class="sectionlink" href="#shelving-v3"
title="Link to this section">¶</a>

<p>Shelving-v3, first introduced in 1.12, can handle more kinds of changes
than Shelving-v2. In particular, it supports shelving of all committable
changes. However, it performs much more slowly than Shelving-v2 and uses more
disk space, especially when used with large working copies.</p>
<p>This version of shelving represents a series of significant refactorings
under the hood to eventually support better shelving, commit checkpointing,
and the possibility of future client-side features for manipulating and

<p>The presence in the working copy of any shelves created by Subversion 1.10
has no effect on a Subversion 1.14 client. Subversion 1.14 will ignore them;
it cannot interoperate with them nor even list their presence.</p>
<p>The <tt>svn upgrade</tt> command has no effect on shelves, as the
working copy format is formally unchanged.</p>
<p>To recover a shelf created by 1.10, either
<ul><li>use a 1.10 client to find and unshelve it, or</li>
<li>as 1.10 shelves are stored as patch files under
<tt><i><WC></i>/.svn/shelves/</tt>, find the patch file and
use any 1.10–1.14 or later <tt>svn patch</tt> to apply it.</li>

<h4>Commit checkpointing (experimental)
<a class="sectionlink" href="#shelving-checkpointing"
title="Link to this section">¶</a>
</h4>
<p>This change was first introduced in 1.11.</p>
<p>Since 1.11, Subversion provides an experimental first cut at solving some
of the use cases envisioned in <a
href="https://issues.apache.org/jira/browse/SVN-3626">issue #3626</a> named
"Commit checkpointing".</p>
<p>It provides the ability to save a snapshot of an uncommitted change from
time to time, and later restore one of those previous versions of your
change back into the working copy.</p>
<p>It does not provide the kind of exact WC state roll back that is also
discussed in that issue, that could make it possible after a messy update to
roll back to the exact WC state that existed just before. This remains a
future possibility.</p>
<p>The ability to checkpoint and roll back an uncommitted change is provided
within the shelving feature, by letting a shelf hold multiple versions of
your change. Therefore, see also <a href="#shelving"> Shelving</a>.</p>
<p>The main checkpointing operations are accomplished by the following
commands, as also listed in
<a href="https://cwiki.apache.org/confluence/x/70cYBQ">the Wiki page</a>:</p>
<table>
<tr><th>Save a checkpoint and continue</th>
<td><tt>svn x-<b>shelf-save</b> foo</tt></td>
<td>copy the local changes into a new version of shelf 'foo';<br/>
doesn't revert the changes from the WC</td>
</tr>
<tr><th>Save a checkpoint and shelve</th>
<td><tt>svn x-<b>shelve</b> foo</tt></td>
<td>move the local changes into a new version of shelf 'foo'<br/>
and revert the changes from the WC</td>
</tr>
<tr><th>Restore / roll back</th>
<td>first revert your unwanted changes; then<br/>

<p>There is an experimental command to write out a view spec describing the

<p>A view spec describes whether each subtree is at a limited depth, excluded,

<h4>The build system prefers Python 2 to Python 3
<a class="sectionlink" href="#autogen_sh-py2-py3"
title="Link to this section">¶</a>
</h4>
<p>Although <a href="#pythonoptional">Python is not required for building
Subversion</a>, it <em>is</em> required for running the test suite, and
therefore, on Unix-like systems, Subversion's build system looks for a Python
executable.</p>
<p>The build system checks the environment variables <tt>$PYTHON</tt>,
<tt>$PYTHON2</tt>, and <tt>$PYTHON3</tt> in this order, followed by the command
names <tt>python</tt>, </tt>python2</tt>, and <tt>python3</tt> (in
<tt>$PATH</tt>) in this order. The first of these that is an executable
implementing Python version 2.7 or greater is used.</p>
<p>Since <a href="#python2">support for Python 2.7 is being phased out</a>, we
expect to change this to prefer Python 3 to Python 2.7 in a 1.14.x patch release.
When we do, we will mention the change in the <tt>CHANGES</tt> file and update
this section of the release notes.</p>
<p>This affects both tarball builds (using <tt>configure</tt>) and working copy
builds (using <tt>autogen.sh</tt>). The release rolling scripts are also
affected.</p>
<p>As a workaround, the environment variable <tt>PYTHON</tt> may be set to the
full path of a Python 3 executable prior to running <tt>configure</tt> (or
<tt>autogen.sh</tt>, if you build from a working copy).</p>

<p>As of 1.14.0, Subversion's test suite does not run correctly with Python 3
on Windows due to differences in the way that Python 2.7 and Python 3 handle
End-Of-Line (EOL) conversions, special characters in pathnames, escaping of
backslashes used in Windows pathnames, and handling of UTF-8 character

<h3>Installed SWIG prevents building Subversion's Python 3 bindings
<a class="sectionlink" href="#issues-building-without-swig"
title="Link to this section">¶</a>
</h3>
<p>When building Subversion from a 1.14.0 distribution tarball, you may not be
able to build Subversion's language bindings for Python 3 if
<tt>configure</tt> detects an unsuitable version of SWIG on your system. This
is a bug because the sources generated by SWIG for Python 3 bindings are
included with the release.</p>
<p>For this situation, a workaround is available as of 1.14.1: pass the
<tt>--without-swig</tt> option to <tt>configure</tt>.</p>
<p>See <a href="http://svn.apache.org/r1876662">r1876662</a>.</p>
<p>The workaround does not apply in the following situations:</p>
<ul>
<li>building Subversion from sources checked out from the repository, where
the SWIG-generated files are not included</li>
<li>building Subversion's SWIG bindings for Python 2.x, in which case SWIG
is needed to regenerate the language bindings because the included ones
target Python 3</li>
</ul>
<p>In these cases, you will need a suitable version of SWIG:</p>
<ul>
<li>To target Python 2: SWIG 2.0.0 through 3.x. (Note that
<tt>configure</tt> will allow SWIG 1.3.24 through 3.x, but SWIG 4.0.0 or
later are not supported for Python 2.)</li>
<li>To target Python 3: SWIG 3.0.10 or later.</li>
