Changelog

Sourced from apache-libcloud's changelog.

Changes in Apache Libcloud 3.3.1

Compute

• [EC2] Fix a regression introduced in v3.3.0 which would break EC2 driver for some regions because the driver would incorrectly try to use signature version 2 for all the regions whereas some newer regions require signature version 4 to be used.

  If you are unable to upgrade, you can use the following workaround, as long as you only use code which supports / works with authentication signature algorithm version 4:

  Reported by @olegrtecno. (GITHUB-1545, GITHUB-1546)

• [EC2] Allow user to override which signature algorithm version is used for authentication by passing signature_version keyword argument to the EC2 driver constructor. (GITHUB-1546)

Storage

• [Google Cloud Storage] Fix a bug and make sure we also correctly handle scenario in get_object() method when the object size is returned in x-goog-stored-content-length and not content-length header.

  Reported by Veith Röthlingshöfer - @RunOrVeith. (GITHUB-1544, GITHUB-1547)

• [Google Cloud Storage] Update get_object() method and ensure object.size attribute is an integer and not a string. This way it's consistent with list_objects() method. (GITHUB-1547)

Changes in Apache Libcloud 3.3.0

Common

• Fix a bug which would cause some prepared requests with empty bodies to be chunked which would cause some of the provider APIs such as OpenStack to return HTTP 400 errors. (GITHUB-1487, GITHUB-1488) [Michael Spagon - @mspagon]

• Optimize various code imports (remove unnecessary imports, make some lazy, etc.), so now importing most of the modules is around ~20-40% faster (~70 vs ~140 ms) and in some cases such as EC2 driver even more.

  Now majority of the import time is spent in importing requests library. (GITHUB-1519) [Tomaz Muraus]

• libcloud.pricing.get_size_price() function has been updated so it only caches pricing data in memory for the requested drivers.

  This way we avoid caching data in memory for drivers which may never be used.

  If you want to revert to old behavior (cache pricing data for all the drivers in memory), you can do that by passing cache_all=True argument to that function or set libcloud.pricing.CACHE_ALL_PRICING_DATA module level variable to True.

  Passing cache_all=True might come handy in situations where you know the application will work with a lot of different drivers - this way you can avoid multiple disk reads when requesting pricing data for different drivers. (GITHUB-1519) [Tomaz Muraus]

• Advertise Python 3.9 support in setup.py.

Compute

• [GCE] Fix ex_set_image_labels method using incorrect API path. (GITHUB-1485) [Poul Petersen - @petersen-poul]
• [OpenStack] Fix error setting ex_force_XXX_url without setting ex_force_base_url. (GITHUB-1492) [Miguel Caballer - @micafer]
• [EC2] Update supported EC2 regions and instance sizes and add support for eu-north-1 region. (GITHUB-1486) [Arturo Noha - @r2ronoha]
