Its design goals are: - * - * - To provide a simple and straightforward API for accessing all of S3's - * functionality - * - To not require the developer using libs3 to need to know anything about: - * - HTTP - * - XML - * - SSL - * In other words, this API is meant to stand on its own, without requiring - * any implicit knowledge of how S3 services are accessed using HTTP - * protocols. - * - To be usable from multithreaded code - * - To be usable by code which wants to process multiple S3 requests - * simultaneously from a single thread - * - To be usable in the simple, straightforward way using sequentialized - * blocking requests - * - * The general usage pattern of libs3 is: - * - * - Initialize libs3 once per program by calling S3_initialize() at program - * start up time - * - Make any number of requests to S3 for getting, putting, or listing - * S3 buckets or objects, or modifying the ACLs associated with buckets - * or objects, using one of three general approaches: - * 1. Simple blocking requests, one at a time - * 2. Multiple threads each making simple blocking requests - * 3. From a single thread, managing multiple S3 requests simultaneously - * using file descriptors and a select()/poll() loop - * - Shut down libs3 at program exit time by calling S3_deinitialize() - * - * All functions which send requests to S3 return their results via a set of - * callback functions which must be supplied to libs3 at the time that the - * request is initiated. libs3 will call these functions back in the thread - * calling the libs3 function if blocking requests are made (i.e., if the - * S3RequestContext for the function invocation is passed in as NULL). - * If an S3RequestContext is used to drive multiple S3 requests - * simultaneously, then the callbacks will be made from the thread which - * calls S3_runall_request_context() or S3_runonce_request_context(), or - * possibly from the thread which calls S3_destroy_request_context(), if - * S3 requests are in progress at the time that this function is called. - * - * NOTE: Response headers from Amazon S3 are limited to 4K (2K of metas is all - * that Amazon supports, and libs3 allows Amazon an additional 2K of headers). - * - * NOTE: Because HTTP and the S3 REST protocol are highly under-specified, - * libs3 must make some assumptions about the maximum length of certain HTTP - * elements (such as headers) that it will accept. While efforts have been - * made to enforce maximums which are beyond that expected to be needed by any - * user of S3, it is always possible that these maximums may be too low in - * some rare circumstances. Bug reports should this unlikely situation occur - * would be most appreciated. - * - * Threading Rules - * --------------- - * - * 1. All arguments passed to any function must not be modified directly until - * the function returns. - * 2. All S3RequestContext and S3Request arguments passed to all functions may - * not be passed to any other libs3 function by any other thread until the - * function returns. - * 3. All functions may be called simultaneously by multiple threads as long - * as (1) and (2) are observed, EXCEPT for S3_initialize(), which must be - * called from one thread at a time only. - * 4. All callbacks will be made in the thread of the caller of the function - * which invoked them, so the caller of all libs3 functions should not hold - * locks that it would try to re-acquire in a callback, as this may - * deadlock. - ************************************************************************** **/ - - -/** ************************************************************************** - * Constants - ************************************************************************** **/ - -/** - * This is the hostname that all S3 requests will go through; virtual-host - * style requests will prepend the bucket name to this host name, and - * path-style requests will use this hostname directly - **/ -#define S3_HOSTNAME "s3.amazonaws.com" - - -/** - * S3_MAX_BUCKET_NAME_SIZE is the maximum size of a bucket name. - **/ - -#define S3_MAX_BUCKET_NAME_SIZE 255 - -/** - * S3_MAX_KEY_SIZE is the maximum size of keys that Amazon S3 supports. - **/ -#define S3_MAX_KEY_SIZE 1024 - - -/** - * S3_MAX_METADATA_SIZE is the maximum number of bytes allowed for - * x-amz-meta header names and values in any request passed to Amazon S3 - **/ -#define S3_MAX_METADATA_SIZE 2048 - - -/** - * S3_METADATA_HEADER_NAME_PREFIX is the prefix of an S3 "meta header" - **/ -#define S3_METADATA_HEADER_NAME_PREFIX "x-amz-meta-" - - -/** - * S3_MAX_METADATA_COUNT is the maximum number of x-amz-meta- headers that - * could be included in a request to S3.
