filecache: unimplement __set__() and __delete__() (API)
Implementing __set__() implies that the descriptor can't be overridden by
obj.__dict__, which means any property access involves slow function call.
"Data descriptors with __set__() and __get__() defined always override
a redefinition in an instance dictionary. In contrast, non-data descriptors
can be overridden by instances."
https://docs.python.org/2.7/reference/datamodel.html#invoking-descriptors
This patch basically backs out 236bb604dc39, "scmutil: update cached copy
when filecached attribute is assigned (issue3263)." The problem described
in issue3263 (which is #3264 in Bugzilla) should no longer happen since
repo._bookmarkcurrent has been moved to repo._bookmarks.active. We still
have a risk of introducing similar bugs, but I think that's the cost we
have to pay.

You must run it from the Windows command prompt (or if you're hard core, a <a href="http://www.mingw.org/">MinGW</a> shell). </p> <p class="indented"> <i>Note: the standard <a href="http://www.mingw.org/">MinGW</a> msys startup script uses rxvt which has problems setting up standard input and output. Running bash directly works correctly.</i> </p> <p> For documentation, please visit the <a href="https://mercurial-scm.org/">Mercurial web site</a>. You can also download a free book, <a href="https://book.mercurial-scm.org/">Mercurial: The Definitive Guide</a>. </p> <p> By default, Mercurial installs to <tt>C:\Program Files\Mercurial</tt>. The Mercurial command is called <tt>hg.exe</tt>. </p> <h1>Testing Mercurial after you've installed it</h1> <p> The easiest way to check that Mercurial is installed properly is to just type the following at the command prompt: </p> <pre> hg </pre> <p> This command should print a useful help message. If it does, other Mercurial commands should work fine for you. </p> <h1>Configuration notes</h1> <h4>Default editor</h4> <p> The default editor for commit messages is 'notepad'. You can set the <tt>EDITOR</tt> (or <tt>HGEDITOR</tt>) environment variable to specify your preference or set it in <tt>mercurial.ini</tt>: </p> <pre> [ui] editor = whatever </pre> <h4>Configuring a Merge program</h4> <p> It should be emphasized that Mercurial by itself doesn't attempt to do a Merge at the file level, neither does it make any attempt to Resolve the conflicts. </p> <p> By default, Mercurial will use the merge program defined by the <tt>HGMERGE</tt> environment variable, or uses the one defined in the <tt>mercurial.ini</tt> file. (see <a href="https://mercurial-scm.org/wiki/MergeProgram">MergeProgram</a> on the Mercurial Wiki for more information) </p> <h1>Reporting problems</h1> <p> Before you report any problems, please consult the <a href="https://mercurial-scm.org/">Mercurial web site</a> and see if your question is already in our list of <a href="https://mercurial-scm.org/wiki/FAQ">Frequently Answered Questions</a> (the "FAQ"). </p> <p> If you cannot find an answer to your question, please feel free to send mail to the Mercurial mailing list, at <a href="mailto:mercurial@mercurial-scm.org">mercurial@mercurial-scm.org</a>. <b>Remember</b>, the more useful information you include in your report, the easier it will be for us to help you! </p> <p> If you are IRC-savvy, that's usually the fastest way to get help.
