Flickcurl 1.13

Flickcurl 1.13 is a versatile C library for the Flickr API, handling creating the requests, signing, token management, calling the API, marshalling request parameters and decoding responses. It uses libcurl to call the REST web service and libxml2 to manipulate the XML responses.

Flickcurl supports all of the API (see Flickcurl API coverage for details) including the functions for photo/video uploading, browsing, searching, adding and editing comments, groups, notes, photosets, categories, activity, blogs, favorites, places, tags, machine tags, institutions, pandas and photo/video metadata. It also includes a program flickrdf to turn photo metadata, tags, machine tags and places into an RDF triples description.

Enhancements:

• Added function flickcurl_source_uri_as_photo_id() to get photo IDs from full raw 'farm' image URLs.
• Added command getphotoid to the command-line utility to allow this to be called.
• Added function flickcurl_get_current_request_wait() so applications can know when flickcurl will delay - sleep(2) - in order to let the web service rate limiting work. This allows the application to avoid this and try again later if it desires, rather than have Flickcurl freeze the entire application (if single threaded).
• Use a dynamic buffer size for request URI construction to avoid crashing when dealing with requests with e.g. long lists of of photo IDs that exceeded the "big enough" buffer for a URI.
  
• After the above problem, reviewed the other fixed buffer sizes in the code and they are all for known fixed uses such as formatting a decimal number (of known size) into a string. None of the remaining ones can be influenced by data passed by API calls.

Requirements:

• libcurl 7.10.0 or newer
• libxml2 2.6.8 or newer
• raptor 1.4.0 (optional), 1.4.14 recommended
