Preview: Bottle 0.12

Marcel Hellkamp — Fri, 19 Jul 2013 18:00:00 +0200

Some time has passed and some really nice features have found their way into the bottle core framework. As we are now preparing for the new release, let me show you the most important changes and let us know what you think about it!

As promised: All changes are fully …

Bottle 0.11 released!

Marcel Hellkamp — Tue, 09 Oct 2012 00:00:00 +0200

The bottle-0.11-rc1 development branch is stable for some time now, widely used and excessively tested. There is no reason to not release it. So, here it is:

PyPi: bottle-0.11 (stable)
Changelog: http://bottlepy.org/docs/0.11/changelog.html#release-0-11

Template Search-Path Workaround

Marcel Hellkamp — Fri, 20 Jul 2012 17:00:00 +0200

One of the most annoying limitations you may encounter in bottle when building bigger applications is the way templates are searched on the file system. At the time the template system was designed, nobody thought about multi-app projects, third-party apps, Bottle.mount() and the complexities these features introduce. The typical …

Virtualenv and Makefiles

Marcel Hellkamp — Mon, 16 Jul 2012 00:00:00 +0200

Whenever I start a new project that is likely to have dependencies, I set up virtualenv and create a requirememnts.txt. I am also a big fan of Makefiles. Here is a small snippet that combines these tools:

# Makefile
venv: venv/bin/activate
venv/bin/activate: requirements.txt
    test -d …

Thread-locals and Generators

Marcel Hellkamp — Fri, 13 Jul 2012 00:00:00 +0200

Looks like the next release (0.11) will break backwards compatibility in some edge cases. I am working on a patch that affects routes that stream content (yield) and access request/response after the first chunk of data is returned.

Details

Accessing the thread-local request/response objects after yielding a …

Bugfix Release 0.10.10

Marcel Hellkamp — Tue, 26 Jun 2012 00:00:00 +0200

Python 3.2+ cgi.FieldStorage() defaults to utf8 when decoding form values. That confused bottle.FormsDict() because WSGI strings "must contain only code points representable in ISO-8859-1 encoding". Now bottle forces cgi.FieldStorage() to use ISO-8859-1 instead and re-encodes form-values on-demand with the user-specified input encoding a intended.

If you …

Bugfix Release 0.10.11

Marcel Hellkamp — Tue, 26 Jun 2012 00:00:00 +0200

The Python 3.x unicode problem was more complex than I thought. I had to re-implement urllib.parse_qsl to work around an encoding problem in 3.1 and change the way bottle handles query-strings in subtle ways. Again, please read this before upgrading: http://bottlepy.org/docs/dev/tutorial.html …

TAL Templates deprecated

Marcel Hellkamp — Mon, 14 May 2012 00:00:00 +0200

Andrea Belvedere found a bug in SimpleTALTemplates that went unnoticed for months. Conclusion: Nobody actually uses Bottle+TAL.

Perhaps it is a good time to remove SimpleTALTemplate support instead of fixing it. Or move it to a plugin.

Here is the deal: The TAL template adapter needs a maintainer or …

Custom Request Attributes

Marcel Hellkamp — Wed, 04 Apr 2012 00:00:00 +0200

This might be useful for Plugin developers: https://github.com/bottlepy/bottle/commit/a21d71694fdea222844dba5076efad3726ccdb68

To sum it up: You can now add custom attributes or properties to the bottle.request object. These are stored in the environ dictionary ('bottle.request.ext.*' namespace) which has some advantages over traditional instance attributes …

Bottlepy.org offline

Marcel Hellkamp — Fri, 17 Feb 2012 00:00:00 +0100

My server harddisk died today. Until I get a new one installed, you can use the mirror at http://readthedocs.org/docs/bottle/en/latest/

Bugfix Release 0.10.7

Marcel Hellkamp — Wed, 28 Dec 2011 00:00:00 +0100

I just released 0.10.7 (security release). It fixes a possible DoS vulnerability that is caused by hash collisions in CPython dicts.

This bug is not specific to bottle. I you are using other frameworks, check for updates there too.

Details: https://cryptanalysis.eu/blog/2011/12/28/effective-dos-attacks-against-web-application-plattforms-hashdos …

Bugfix Release 0.9.8 and 0.10.5

Marcel Hellkamp — Thu, 22 Dec 2011 00:00:00 +0100

I just released 0.10.5 and 0.9.8. Both are security bugfix releases and recommended for everyone. Here is a brief summary of the changes:

Critical errors (errors within the framework code) resulted in an error page that was not protected against XSS attacks (because the template engine …

Native Py3k support merged

Marcel Hellkamp — Tue, 20 Dec 2011 00:00:00 +0100

It was a lot of work, but I could finally drop the 2to3 requirement! The Bottle sources now support Python 2.5, 2.6, 2.7, 3,1 and 3.2 natively. All tests pass. No measurable performance drawback. Full backwards compatible. Its pure win :)

You can test it directly …

Bottle 0.10 released!

Marcel Hellkamp — Sat, 26 Nov 2011 00:00:00 +0100

There is a lot of new stuff this time: A CLI interface, new routing syntax and lots of convenient helpers for request/response objects and templates. The change-log will tell you more.

Changelog: http://bottlepy.org/docs/0.10/changelog.html#release-0-10
PyPi link: http://pypi.python.org/pypi/bottle …

Native Python 2.x-3.x support

Marcel Hellkamp — Fri, 25 Nov 2011 00:00:00 +0100

A few days ago, Ralf showed us his version of Bottle 0.9 that supports python 2.x and 3.x from a single source. No need to run 2to3 anymore, it runs natively with both major versions of Python.

I want that!

So I created a new branch and …

Bugfix release 0.9.7

Marcel Hellkamp — Tue, 15 Nov 2011 00:00:00 +0100

Bottle 0.9.7 (bugfix release) is available. The bug: Loading a template encoded with a codec other than the system default in a Python 3.x environment raised an unicode error under certain circumstances. So, this release is optional. Ignore it if you want :)

More robust Auto-reload

Marcel Hellkamp — Tue, 15 Nov 2011 00:00:00 +0100

The Bottle auto-reload feature got an upgrade today: It is now able to handle syntax and import errors in your application or imported modules. Just start the server with the new command-line interface and give it a try:

bottle.py --debug --reload package.module:app

I had to change a …

Feature freeze for 0.10

Marcel Hellkamp — Thu, 10 Nov 2011 00:00:00 +0100

Feature freeze, lets fix some bugs :)

What is in:

http://bottlepy.org/docs/dev/changelog.html#release-0-10
plus the new route (filter) syntax

Notable stuff that has to wait for 0.11:

New TemplateAdapter API
SimpeTemplate v2
Comamnd-line reloader that can handle syntax errors.
Testing API for bottle apps (needs …

Routing Overhaul

Marcel Hellkamp — Wed, 09 Nov 2011 00:00:00 +0100

It took some time, but the new routing code is finished.

Highlights:

New wildcard syntax: /object/<id:int>
Wildcard filtering/validation as part of the route syntax
Support for custom wildcard filters
Faster url() building
Better error messages
Much simpler code (I dropped CGI optimization)
Lots of documentation
(the old …
