Make CSV import/export compatible across Python versions (also RDBMS journals) (issue 2550976, issue 2550975).
The roundup-admin export and import commands are used for migrating
between different database backends. It is desirable that they should
be usable also for migrations between Python 2 and Python 3, and in
some cases (e.g. with the anydbm backend) this may be required.
To be usable for such migrations, the format of the generated CSV
files needs to be stable, meaning the same as currently used with
Python 2. The export process uses repr() to produce the fields in the
CSV files and eval() to convert them back to Python data structures.
repr() of strings with non-ASCII characters produces different results
for Python 2 and Python 3.
This patch adds repr_export and eval_import functions to
roundup/anypy/strings.py which provide the required operations that
are just repr() and eval() in Python 2, but are more complicated in
Python 3 to use data representations compatible with Python 2. These
functions are then used in the required places for export and import.
repr() and eval() are also used in storing the dict of changed values
in the journal for the RDBMS backends. It is similarly desirable that
the database be compatible between Python 2 and Python 3, so that
export and import do not need to be used for a migration between
Python versions for non-anydbm back ends. Thus, this patch changes
rdbms_common.py in the places involved in storing journals in the
database, not just in those involved in import/export.
Given this patch, import/export with non-ASCII characters appear based
on some limited testing to work across Python versions, and an
instance using the sqlite backend appears to be compatible between
Python versions without needing import/export, *if* the sessions/otks
databases (which use anydbm) are deleted when changing Python version.

# [Twitter Bootstrap v2.2.2](http://twitter.github.com/bootstrap) [](http://travis-ci.org/twitter/bootstrap) Bootstrap is a sleek, intuitive, and powerful front-end framework for faster and easier web development, created and maintained by [Mark Otto](http://twitter.com/mdo) and [Jacob Thornton](http://twitter.com/fat). To get started, checkout http://getbootstrap.com! ## Quick start Three quick start options are available: * [Download the latest release](https://github.com/twitter/bootstrap/zipball/master). * Clone the repo: `git clone git://github.com/twitter/bootstrap.git`. * Install with Twitter's [Bower](http://twitter.github.com/bower): `bower install bootstrap`. ## Versioning For transparency and insight into our release cycle, and for striving to maintain backward compatibility, Bootstrap will be maintained under the Semantic Versioning guidelines as much as possible. Releases will be numbered with the following format: `<major>.<minor>.<patch>` And constructed with the following guidelines: * Breaking backward compatibility bumps the major (and resets the minor and patch) * New additions without breaking backward compatibility bumps the minor (and resets the patch) * Bug fixes and misc changes bumps the patch For more information on SemVer, please visit http://semver.org/. ## Bug tracker Have a bug or a feature request? [Please open a new issue](https://github.com/twitter/bootstrap/issues). Before opening any issue, please search for existing issues and read the [Issue Guidelines](https://github.com/necolas/issue-guidelines), written by [Nicolas Gallagher](https://github.com/necolas/). ## Community Keep track of development and community news. * Follow [@twbootstrap on Twitter](http://twitter.com/twbootstrap). * Read and subscribe to the [The Official Twitter Bootstrap Blog](http://blog.getbootstrap.com). * Have a question that's not a feature request or bug report? [Ask on the mailing list.](http://groups.google.com/group/twitter-bootstrap) * Chat with fellow Bootstrappers in IRC. On the `irc.freenode.net` server, in the `##twitter-bootstrap` channel. ## Developers We have included a makefile with convenience methods for working with the Bootstrap library. + **dependencies** Our makefile depends on you having recess, connect, uglify.js, and jshint installed. To install, just run the following command in npm: ``` $ npm install recess connect uglify-js jshint -g ``` + **build** - `make` Runs the recess compiler to rebuild the `/less` files and compiles the docs pages. Requires recess and uglify-js. <a href="http://twitter.github.com/bootstrap/extend.html#compiling">Read more in our docs »</a> + **test** - `make test` Runs jshint and qunit tests headlessly in [phantomjs](http://code.google.com/p/phantomjs/) (used for ci). Depends on having phantomjs installed. + **watch** - `make watch` This is a convenience method for watching just Less files and automatically building them whenever you save. Requires the Watchr gem. ## Contributing Please submit all pull requests against *-wip branches. If your pull request contains JavaScript patches or features, you must include relevant unit tests. All HTML and CSS should conform to the [Code Guide](http://github.com/mdo/code-guide), maintained by [Mark Otto](http://github.com/mdo).
