New Features and Bug Fixes

2010-03-10, By Decker:

• upgraded server code to WCS version 1.1.2 requirements
• implemented minimum requirements for WCS 1.1.2
• totally restructured wcs.py in the process to be able to support new versions more easily in the future (hopefully)
• versions 1.1.0 and 1.1.1 will be treated by the same code as 1.1.2 as no real protocol differences were found in the spec documents
• introduced wcs_capabilities.conf in provider dir to provide some static but provider specific settings (Contact, Title, etc); also see inline documentation in that file
• moved providers from static to own providers dir, so that provider data is not freely accessible via static path any more
• index.html contents will now be delivered via owsutil.StringResponse
• moved logs out of static
• changed owsadmin from a tool generating static xml documents to a tool that collects all relevant metadata for realtime generation of XML responses to all requests
• metadata is saved as a pickled nested dict in "metadata.dat" in the provider dir -> completely removed template concept
• added get_range method to all relevant iso_time Time classes
• changed pync3 time filtering code to handle exact points in time and time ranges
• added very basic support for multiple CRS definitions
• introduced config.float_precision to globally set number of digits that floats should be rounded to before comparing them
• added config options for supported formats and CRSs to be announced in responses
• updated inline documentation
• moved ows_name, wcs_name, etc. from owsadmin to owsutil
• updated ExceptionReport generation
• owsparser will not mask ";" characters any more as they should be escaped (%3B) if they are not meant to be interpreted by the parser

2010-04-02, By Hoijarvi:

• Added more query unit tests.

2010-04-05, By Hoijarvi:

• Upgraded to NetCDF 4 library. This version allows cubes bigger than 2 GB to be used as data source.

2010-04-07, By Decker:

• Internal improvements in ISO 8609 time parsing, correctly rejecting time zone information from full dates without time.
• Darcs update: upgraded the repository format from the original to darcs-2. New darcs access requires darcs 2

2010-04-09, By Hoijarvi:

• Homepages of the service and the providers are now redirected properly, so the html documents can use relative addresses for images and other hyperlinks.
• Added real W3C-Schema based XML validation for Capabilities and Coverage Descriptions, fixed automated creation of them.

2010-04-14, By Hoijarvi:

• Fixed NCML interpretation to avoid accumulation of rounding errors when creating values for dimension variables.
• Allowed querying without bbox. The spec requires either time or bbox filter.

2010-04-15, By Hoijarvi:

• Re-enabled month, day_of_week, and hour_of_day filters to allow queries like: every noon hour of every weekend in every summer month. This is a non-standard extension.
• switched from standard python urlparse to own version, to allow semicolon to be used as a separator as it is used in specs.

2010-04-27, By Hoijarvi:

• Optimization to allow big queries: 500 MB cubes used to cause out of memory exception.
• Optimized datafed client to do big aggregations with multiple small queries. This enables aggregation of multi-gigabyte queries.

2010-04-29, By Hoijarvi:

• Fix to allow dimensions to have only one coordinate.

2010-05-05, By Decker:

• remove unused imports from desc_t
• updated webpy_logger to wsgilog 0.2
• improved query parser (parse_qsl)
• improved is_num_type()
