Introduction + 2. Thread Safety + 3. Pool Usage + 4. Bucket Read Functions + 5. Versioning + 6. Bucket lifetimes + + +----------------------------------------------------------------------------- + +1. INTRODUCTION + +This document details various design choices for the serf library. It +is intended to be a guide for serf developers. Of course, these design +principles, choices made, etc are a good source of information for +users of the serf library, too. + + +----------------------------------------------------------------------------- + +2. THREAD SAFETY + +The serf library should contain no mutable globals, making it is safe +to use in a multi-threaded environment. + +Each "object" within the system does not need to be used from multiple +threads at a time. Thus, they require no internal mutexes, and can +disable mutexes within APR objects where applicable (e.g. pools that +are created). + +The objects should not have any thread affinity (i.e. don't use +thread-local storage). This enables an application to use external +mutexes to guard entry to the serf objects, which then allows the +objects to be used from multiple threads. + + +----------------------------------------------------------------------------- + +3. POOL USAGE + +For general information on the proper use of pools, please see: + + http://cvs.apache.org/viewcvs/*checkout*/apr/docs/pool-design.html + +Within serf itself, the buckets introduce a significant issue related +to pools. Since it is very possible to end up creating *many* buckets +within a transaction, and that creation could be proportional to an +incoming or outgoing data stream, a lot of care must be take to avoid +tying bucket allocations to pools. If a bucket allocated any internal +memory against a pool, and if that bucket is created an unbounded +number of times, then the pool memory could be exhausted. + +Thus, buckets are allocated using a custom allocator which allows the +memory to be freed when that bucket is no longer needed. This +contrasts with pools where the "free" operation occurs over a large +set of objects, which is problematic if some are still in use. + +### need more explanation of strategy/solution ... + + +----------------------------------------------------------------------------- + +4. BUCKET READ FUNCTIONS + +The bucket reading and peek functions must not block. Each read +function should return (up to) the specified amount of data. If +SERF_READ_ALL_AVAIL is passed, then the function should provide +whatever is immediately available, without blocking. + +The peek function does not take a requested length because it is +non-destructive. It is not possible to "read past" any barrier with a +peek function. Thus, peek should operate like SERF_READ_ALL_AVAIL. + +The return values from the read functions should follow this general +pattern: + + APR_SUCCESS Some data was returned, and the caller can + immediately call the read function again to read + more data. + + NOTE: when bucket behavior tracking is enabled, + then you must read more data from this bucket + before returning to the serf context loop. If a + bucket is not completely drained first, then it is + possible to deadlock (the server might not read + anything until you read everything it has already + given to you). + + APR_EAGAIN Some data was returned, but no more is available + for now. The caller must "wait for a bit" or wait + for some event before attempting to read again + (basically, this simply means re-run the serf + context loop). Though it shouldn't be done, reading + again will, in all likelihood, return zero length + data and APR_EAGAIN again. + + NOTE: when bucket behavior tracking is enabled, + then it is illegal to immediately read a bucket + again after it has returned APR_EAGAIN. You must + run the serf context loop again to (potentially) + fetch more data for the bucket. + + APR_EOF Some data was returned, and this bucket has no more + data available and should not be read again. If you + happen to read it again, then it will return zero + length data and APR_EOF. + + NOTE: when bucket behavior tracking is enabled, + then it is illegal to read this bucket ever again. + + other An error has occurred. No data was returned. The + returned length is undefined. + +In the above paragraphs, when it says "some data was returned", note +that this could be data of length zero. + +If a length of zero is returned, then the caller should not attempt to +dereference the data pointer. It may be invalid. Note that there is no +reason to dereference that pointer, since it doesn't point to any +valid data. + +Any data returned by the bucket should live as long as the bucket, or +until the next read or peek occurs. + +The read_bucket function falls into a very different pattern. See its +doc string for more information. + + +----------------------------------------------------------------------------- + +5. VERSIONING + +The serf project uses the APR versioning guidelines described here: + + http://apr.apache.org/versioning.html + + +----------------------------------------------------------------------------- + +6. BUCKET LIFETIMES + +### flesh out. basically: if you hold a bucket pointer, then you own +### it. passing a bucket into another transfers ownership. use barrier +### buckets to limit destruction of a tree of buckets. + + +----------------------------------------------------------------------------- diff --git a/incoming.c b/incoming.c new file mode 100644 index 0000000..40562fa --- /dev/null +++ b/incoming.c @@ -0,0 +1,176 @@ +/* Copyright 2002-2004 Justin Erenkrantz and Greg Stein + * + * Licensed under the Apache License, Version 2.0 (the "License");
