-/*
- * The one-sentence buzzword-laden overview: Bucket brigades represent
- * a complex data stream that can be passed through a layered IO
- * system without unnecessary copying. A longer overview follows...
- *
- * A bucket brigade is a doubly linked list of buckets, so we
- * aren't limited to inserting at the front and removing at the end.
- * Buckets are only passed around as members of a brigade, although
- * singleton buckets can occur for short periods of time.
- *
- * Buckets are data stores of varous types. They can refer to data in
- * memory, or part of a file or mmap area, or the output of a process,
- * etc. Buckets also have some type-dependent accessor functions:
- * read, split, copy, setaside, and destroy.
- *
- * read returns the address and size of the data in the bucket. If the
- * data isn't in memory then it is read in and the bucket changes type
- * so that it can refer to the new location of the data. If all the
- * data doesn't fit in the bucket then a new bucket is inserted into
- * the brigade to hold the rest of it.
- *
- * split divides the data in a bucket into two regions. After a split
- * the original bucket refers to the first part of the data and a new
- * bucket inserted into the brigade after the original bucket refers
- * to the second part of the data. Reference counts are maintained as
- * necessary.
- *
- * setaside ensures that the data in the bucket has a long enough
- * lifetime. Sometimes it is convenient to create a bucket referring
- * to data on the stack in the expectation that it will be consumed
- * (output to the network) before the stack is unwound. If that
- * expectation turns out not to be valid, the setaside function is
- * called to move the data somewhere safer.
- *
- * copy makes a duplicate of the bucket structure as long as it's
- * possible to have multiple references to a single copy of the
- * data itself.  Not all bucket types can be copied.
- *
- * destroy maintains the reference counts on the resources used by a
- * bucket and frees them if necessary.
- *
- * Note: all of the above functions have wrapper macros (ap_bucket_read(),
- * ap_bucket_destroy(), etc), and those macros should be used rather
- * than using the function pointers directly.
- *
- * To write a bucket brigade, they are first made into an iovec, so that we
- * don't write too little data at one time.  Currently we ignore compacting the
- * buckets into as few buckets as possible, but if we really want good
- * performance, then we need to compact the buckets before we convert to an
- * iovec, or possibly while we are converting to an iovec.
