+
+* Version 0.17 or newer of the Cython_ compiler.
+
+* Version 1.1 or newer of the Sphinx_ document processor.
+
+* The `py.test`_ testing tool, version 2.3.3 or newer.
+
+With these additional dependencies installed, S3QL can be build and
+tested with ::
+
+  python3 setup.py build_cython
+  python3 setup.py build_ext --inplace
+  py.test tests/
+
+Note that when building from the Mercurial repository, building and
+testing is done with several additional checks. This may cause
+compilation and/or tests to fail even though there are no problems
+with functionality. For example, when building from the Mercurial
+repository, any use of functions that are scheduled for deprecation in
+future Python version will cause tests to fail. If you would rather
+just check for functionality, you can delete the :file:`MANIFEST.in`
+file. In that case, the build system will behave as it does for a
+regular release.
+

+
+Running tests requiring remote servers
+======================================
+
+By default, the `runtest.py` (or `py.test`) script skips all tests
+that require connection to a remote storage backend. If you would like
+to run these tests too (which is always a good idea), you have to
+create additional entries in your `~/.s3ql/authinfo2` file that tell
+S3QL what server and credentials to use for these tests. These entries
+have the following form::
+
+  [<BACKEND>-test]
+  backend-login: <user>
+  backend-password: <password>
+  test-fs: <storage-url>
+
+Here *<BACKEND>* specifies the backend that you want to test
+(e.g. *s3*, *s3c*, *gs*, or *swift*), *<user>* and *<password>* are
+the backend authentication credentials, and *<storage-url>* specifies
+the full storage URL that will be used for testing. **Any existing
+S3QL file system in this storage URL will be destroyed during
+testing**.
+
+For example, to run tests that need connection to a Google Storage
+server, you would add something like ::
+
+  [gs-test]
+  backend-login: GOOGIGWLONT238MD7HZ4
+  backend-password: rmEbstjscoeunt1249oes1298gauidbs3hl
+  test-fs: gs://joes-gs-bucket/s3ql_tests/
+
+On the next run of `runtest.py` (or `py.test` when using the
+development version), the additional tests will be run. If the tests
+are still skipped, you can get more information about why tests are
+being skipped by passing the :cmdopt:`-rs` argument to
+`runtest.py`/`py.test`.

 Known Issues
 ============
 
+* S3QL de-duplicates data blocks based solely only on SHA256
+  checksums, without doing a byte-by-byte comparison of the blocks.
+  Since it is possible for two data blocks to have the same checksum
+  despite having different contents, this can lead to problems. If two
+  such blocks are stored in an S3QL file system, the data in one block
+  will be lost and replaced by the data in the other block. However,
+  the chances of this occuring for any two blocks are about 1 in 10^77
+  (2^256). For a file system that holds a total of 10^34 blocks, the
+  chances of a collision increase to about 1 in 10^9. Storing more
+  than 10^34 blocks (or about 10^25 TB with an (extremely small) block
+  size of 4 kB) is therefore not recommended. Being exceptionally
+  unlucky may also be a disadvantage.
+
 * S3QL does not support Access Control Lists (ACLs). This is due to
   a bug in the FUSE library and will therefore hopefully be fixed
   at some point. See `issue 385 <http://code.google.com/p/s3ql/issues/detail?id=385>`_
   for more details.
 
-* S3QL 1.x does not verify TLS/SSL server certificates and is thus
-  vulnerable to man-in-the-middle attacks (S3QL versions after 2.0
-  do not have this problem but require Python 3.3 or newer).
-
 * S3QL is rather slow when an application tries to write data in
   unreasonably small chunks. If a 1 MiB file is copied in chunks of 1
   KB, this will take more than 10 times as long as when it's copied

+<h2>Running tests requiring remote servers<a class="headerlink" href="#running-tests-requiring-remote-servers" title="Permalink to this headline">¶</a></h2>
+<p>By default, the <tt class="docutils literal"><span class="pre">runtest.py</span></tt> (or <tt class="docutils literal"><span class="pre">py.test</span></tt>) script skips all tests
+that require connection to a remote storage backend. If you would like
+to run these tests too (which is always a good idea), you have to
+create additional entries in your <tt class="docutils literal"><span class="pre">~/.s3ql/authinfo2</span></tt> file that tell
+S3QL what server and credentials to use for these tests. These entries
+have the following form:</p>
+<div class="highlight-commandline"><div class="highlight"><pre><span class="ge">[&lt;BACKEND&gt;-test]</span><span class="l"></span>
+<span class="l">backend-login: </span><span class="nv">&lt;user&gt;</span><span class="l"></span>
+<span class="l">backend-password: </span><span class="nv">&lt;password&gt;</span><span class="l"></span>
+<span class="l">test-fs: </span><span class="nv">&lt;storage-url&gt;</span><span class="l"></span>
+</pre></div>
+</div>
+<p>Here <em>&lt;BACKEND&gt;</em> specifies the backend that you want to test
+(e.g. <em>s3</em>, <em>s3c</em>, <em>gs</em>, or <em>swift</em>), <em>&lt;user&gt;</em> and <em>&lt;password&gt;</em> are
+the backend authentication credentials, and <em>&lt;storage-url&gt;</em> specifies
+the full storage URL that will be used for testing. <strong>Any existing
+S3QL file system in this storage URL will be destroyed during
+testing</strong>.</p>
+<p>For example, to run tests that need connection to a Google Storage
+server, you would add something like</p>
+<div class="highlight-commandline"><div class="highlight"><pre><span class="ge">[gs-test]</span><span class="l"></span>
+<span class="l">backend-login: GOOGIGWLONT238MD7HZ4</span>

+<p>On the next run of <tt class="docutils literal"><span class="pre">runtest.py</span></tt> (or <tt class="docutils literal"><span class="pre">py.test</span></tt> when using the
+development version), the additional tests will be run. If the tests

+checksums, without doing a byte-by-byte comparison of the blocks.
+Since it is possible for two data blocks to have the same checksum
+despite having different contents, this can lead to problems. If two
+such blocks are stored in an S3QL file system, the data in one block
+will be lost and replaced by the data in the other block. However,
+the chances of this occuring for any two blocks are about 1 in 10^77
+(2^256). For a file system that holds a total of 10^34 blocks, the
+chances of a collision increase to about 1 in 10^9. Storing more
+than 10^34 blocks (or about 10^25 TB with an (extremely small) block
+size of 4 kB) is therefore not recommended. Being exceptionally

+\end{Verbatim}
+
+Note that when building from the Mercurial repository, building and
+testing is done with several additional checks. This may cause
+compilation and/or tests to fail even though there are no problems
+with functionality. For example, when building from the Mercurial
+repository, any use of functions that are scheduled for deprecation in
+future Python version will cause tests to fail. If you would rather
+just check for functionality, you can delete the \code{MANIFEST.in}
+file. In that case, the build system will behave as it does for a
+regular release.

+S3QL de-duplicates data blocks based solely only on SHA256
+checksums, without doing a byte-by-byte comparison of the blocks.
+Since it is possible for two data blocks to have the same checksum
+despite having different contents, this can lead to problems. If two
+such blocks are stored in an S3QL file system, the data in one block
+will be lost and replaced by the data in the other block. However,
+the chances of this occuring for any two blocks are about 1 in 10\textasciicircum{}77
+(2\textasciicircum{}256). For a file system that holds a total of 10\textasciicircum{}34 blocks, the
+chances of a collision increase to about 1 in 10\textasciicircum{}9. Storing more
+than 10\textasciicircum{}34 blocks (or about 10\textasciicircum{}25 TB with an (extremely small) block
+size of 4 kB) is therefore not recommended. Being exceptionally
+unlucky may also be a disadvantage.
+
+\item {} 
 S3QL does not support Access Control Lists (ACLs). This is due to
 a bug in the FUSE library and will therefore hopefully be fixed
 at some point. See \href{http://code.google.com/p/s3ql/issues/detail?id=385}{issue 385}
 for more details.
