Change Log

A list of per-release changes in the Tangelo codebase. Tangelo uses semantic versioning.

[Unreleased] - [unreleased]

[0.10] - 2016-01-25

Added

  • Traceback is logged when a service module can't be imported
  • Improvements to release cycle documentation
  • Configuration parameter for $.controlPanel to set height of open panel explicitly
  • Documentation has an explicit "hello world" example in the Quick Start section
  • Quiet option reduces verbosity
  • "Watch" plugin controls whether services and dependent modules are automatically reloaded when they change
  • tangelo.ensurePlugin() function that avoids JavaScript parsing problems
  • Service functions tangelo.redirect() and tangelo.internal_redirect() to allow services to redirect to other resources
  • Service function tangelo.file() to serve arbitrary files
  • Configuration file takes CherryPy configuration options to apply at startup in server_settings property
  • tangelo.util.set_server_setting() can be used to update CherryPy settings at runtime

Changed

  • Documentation introduction is more focused; tutorials are more front-and-center
  • Updated bundled version of GeoJS
  • Support Travis containers for better automated testing
  • Verbose option can be specified multiple times to increase application verbosity
  • --config option can now accept either a YAML filename or a raw JSON string
  • Tangelo no longer automatically reloads changed service modules, unless the --watch option is specified to load the new watch plugin
  • Bundled Mongo plugin updated to use PyMongo 3.2

Deprecated

  • tangelo.getPlugin() - use tangelo.ensurePlugin() instead

Removed

  • "System Architecture" section in README

Fixed

  • tangelo.paths(".") hack no longer necessary to import modules in same directory as service
  • Persistent store no longer cleared when reloading service
  • Verbose option (-v) properly increases application verbosity
  • Plugins are now imported using the imp module, eliminating some spurious error messages

Security

  • Server response header now reads "Tangelo" instead of "CherryPy" with a version string
  • Runtime exceptions no longer send tracebacks to the client; instead, an error report code is sent, which can be matched up to a traceback appearing in the server log

[0.9] - 2015-03-03

Added

  • This change log file
  • Improvements to style testing
  • Improvements to coverage testing
  • Serverside and command line version tests
  • New security features: by default Tangelo no longer serves directory contents, Python source code, and web service configuration files
  • --examples flag causes example applications to be served; default web root is now . (i.e. directory from which Tangelo was invoked)
  • SQLAlchemy-based visualization tutorial
  • Plugins can now be specified without a path, causing Tangelo to look for a bundled plugin of that name
  • New tangelo-pkgdata executable reports filesystem path to Tangelo package data

Changed

  • Cross-platform generation of tangelo and tangelo-passwd executable files (tested on Linux, Windows, and OS X)
  • Loosened dependency requirement on CherryPy
  • System path is no longer modified to make service module available to import system; instead, the current working directory is changed to that of the service file
  • Configuration file is now typechecked at load time, including reporting of unexpected options, with errors resulting in fail-fast
  • Plugins are now specified in the plugins entry of the main configuration file
  • Plugins no longer require an enabled property; all plugins listed in the configuration file will be loaded
  • Build process uses setuptools instead of distutils
  • Example webpage and bundled plugins are now treated as package data (i.e., stored directly in site-packages, etc.)

Removed

  • Service of web content from home directories
  • tangelo.abspath() - web services should instead use tangelo.server.analyze_url() to learn the disk path for a given web resource
  • systemd support materials, as well as plans to provide other system service helpers

Fixed

  • tangelo.plugin_config() works
  • Python module path behaves correctly in plugin web directories
  • tangelo.server.analyze() works better, especially for plugin development
  • Informational log output now goes unilaterally to sys.stderr while access logs go to sys.stdout
  • Nodelink example fixed so that contents are visible

[0.8.1] - 2015-01-16

Fixed

  • Search logic for default examples no longer fails on certain systems

[0.8] - 2014-12-12

This release breaks backward compatibility with Tangelo 0.7 and previous. Future releases will be described in this file as a change log against previous releases, with 0.8 being the earliest such documented point.

Added

  • Assorted API functions
