To call a synchronous (i.e. normal) function from an asynchronous + * function, just call it as you would normally. + * + * async functions can have a result, which will be stored in the __async_result + * field of their state structure. Callers can access this result via the + * async_result macro. + * + * Managing execution + * ------------------ + * + * There are two general styles of asynchronous functions: polling-based and + * callback-based. + * + * Polling-based functions + * ----------------------- + * + * For polling-based functions, you would generally call them from a + * synchronous function by doing: + * function_state_init(&func_state, params...); + * while (!async_call(function, &func_state)) + * do_something_else_or_sleep_or_whatever(); + * + * Call-back-based functions + * ------------------------- + * + * Callback-based async functions are appropriate when you have some way of + * receiving external notification that the awaited event has occured, and you + * want to notify your callers that they can now resum execution of your code. + * One example might be an asynchronous I/O library that calls a callback when + * I/O completes. + * + * Callback-based functions introduce two complications: one at the callee side + * and one at the caller side. The callee needs to remember all the function + * executions that are waiting for an event to occur. This library includes a + * simple wait queue mechanism that async function writers can use for this + * purpose. You can use async_wait_on_queue to atomically test whether a + * condition is true and, if not, add your execution to a given wait queue and + * suspend execution. See laio.c and clockcache.c for examples. + * + * On the caller side, you generally maintain a pool of the states of running + * function executions, and the callback you pass to your async function simply + * flags its corresponding execution state as ready to resume execution, either + * by setting some flag or moving it to a ready-to-run queue. See the tests for + * examples. + * + * Finally, if you want to call an asynchronous function and simply wait for its + * completion synchronously, you can use async_call_sync_callback_function. Note + * this macro assumes that the callback and callback_arg parameters are the last + * parameters of the asynchronous function's state init method. There is + * currently no correpsonding macro for polling-based async functions, but only + * because we currently have no need for one. + * + * Sub-routines + * ------------ + * + * Sometimes it is useful to break an asynchronous function into a top-level + * function that calls several async subroutines. The straightforward way to do + * this is to create a state structure for each subroutine and follow the + * methodology described above. However, this can be tedious and wasteful. + * Sometimes it is preferable to simply have all the subroutines use the same + * state structure as the top-level function. + * + * This is fine, except that each subroutine needs its own async_state field to + * record where it suspended execution. Thus, the state structure for an + * asychronous function (or function and collection of subroutines) must have an + * array of async_states, which are used as a stack. This is why the + * DEFINE_ASYNC_STATE has a height parameter -- to specify the maximum height of + * the stack of subroutines. + * + * Thus there are two slightly different types of asynchronous functions: + * top-level async functions and their subroutines. Top-level functions take a + * single parameter -- a pointer to their state stucture. They should call + * async_begin with a depth of 0. Subroutines take a pointer to the state and a + * depth parameter. To call a subroutine, you can use the async_await_subroutine + * macro, which will pass the correct depth parameter. + * + * The depth parameter cannot be stored in the state structure because doing so + * would introduce race conditions, as described below. + * + * A note on races + * --------------- + * + * One issue to keep in mind when extending this module is to avoid a race + * condition with callback-based functions. The issue is that, when an async + * function suspends execution, it still has to unwind the run-time stack of all + * its async ancestors. If that async function saved its state on a wait queue, + * then its top-level caller could get notified that the function is ready to + * resume execution betore the original execution finishes unwinding its stack. + * Then another thread could resume execution of the same async state before the + * original execution has finished unwinding its stack. Thus it is imperative + * that, during the stack unwinding process, async functions must not read or + * modify their state. They must simply return to their caller. See, for + * example, async_yield_after for more details. */ #pragma once +/* Async functions return async_status. ASYNC_STATUS_RUNNING means that the + * function has not yet completed.

The memtable locks itself to inserts - * (but not lookups), Splinter switches the active memtable, - * then the filter is built from the fp_arr, and the - * btree in the memtable is inserted into the - * root as a new (distinct) branch. Then the memtable is - * reinitialized with a new (empty) btree and unlocked. - * - * Flushing - * A node is considered full when it has max_tuples_per_node tuples - * (set to be fanout * memtable_capacity) or when it has - * max_branches_per_node branches. The first condition ensures that - * data moves down the tree and the second limits the number of - * branches on a root-to-leaf path and therefore the worst-case lookup - * cost. - * - * When a node fills, a flush is initiated to each pivot (child) of - * the node which has at least max_branches_per_node live branches. If - * the node is still full, it picks the pivot which has the most - * tuples and flushes to that child and repeats this process until the - * node is no longer full. - * - * A flush consists of flushing all the branches which are live for - * the pivot into a bundle in the child. A bundle is a contiguous - * range of branches in a trunk node, see trunk node documentation - * below. A flush to a given pivot makes all branches and bundles in - * the parent no longer "live" for that pivot. - * - * Compaction (after flush) - * After a flush completes, a compact_bundle job is issued for the - * bundle which was created. This job first checks if the node is full - * and if so flushes until it is no longer full. Then it compacts all - * the tuples in the bundle which are live for the node (are within - * the node's key range and have not been flushed), and replaces the - * bundle with the resulting compacted branch. - * - * Split (internal) - * During a flush, if the child has more pivots than the configured - * fanout, it is split. Note that pivots are added at other times (to - * the parent of an internal or leaf split), so nodes may - * temporarily exceed the fanout. Splits are not initiated then, - * because the hand-over-hand locking protocol means that the lock of - * the grandparent is not held and it is awkward for try to acquire - * locks going up the tree. - * - * An internal node split is a logical split: the trunk node is - * copied, except the first (fanout/2) pivots become the pivots of - * the left node and the remaining pivots become the right node. No - * compaction is initiated, and the branches and bundles of the node - * pre-split are shared between the new left and right nodes. - * - * Split (leaf) - * When a leaf has more than cfg->max_tuples_per_node (fanout * - * memtable_capacity), it is considered full. - * - * When a leaf is full, it is split logically: new pivots are - * calculated, new leaves are created with those pivots as min/max - * keys, and all the branches in the leaf at the time of the split are - * shared between them temporarily as a single bundle in each. This - * split happens synchronously with the flush. - * - * A compact_bundle job is issued for each new leaf, which - * asynchronously compacts the shared branches into a single unshared - * branch with the tuples from each new leaf's range. - *----------------------------------------------------------------------------- - */ - -/* - *----------------------------------------------------------------------------- - * Interactions between Concurrent Processes - * - * The design of SplinterDB allows flushes, compactions, internal node - * split and leaf splits to happen concurrently, even within the same - * node. The ways in which these processes can interact are detailed - * here. - * - * o Flushes and compactions: - * - * 1. While a compaction has been scheduled or is in process, a flush may - * occur. This will flush the bundle being compacted to the child and - * the in-progress compaction will continue as usual. Note that the - * tuples which are flushed will still be compacted if the compaction - * is in progress, which results in some wasted work. - * 2. As a result of 1., while a compaction has been scheduled, its - * bundle may be flushed to all children, so that it is no longer - * live. In this case, when the compact_bundle job initiates, it - * detects that the bundle is not live and aborts before compaction. - * 3. Similarly, if the bundle for an in-progress compaction is flushed - * to all children, when it completes, it will detect that the bundle - * is no longer live and it will discard the output. - * - * o Flushes and internal/leaf splits: - * - * Flushes and internal/leaf splits are synchronous and do not - * interact. - * - * o Internal splits and compaction: - * - * 4. If an internal split occurs in a node which has a scheduled - * compaction, when the compact_bundle job initiates it will detect - * the node split using the node's generation number - * (hdr->generation). It then creates a separate compact_bundle job on - * the new sibling. - * 5. If an internal split occurs in a node with an in-progress - * compaction, the bundle being compacted is copied to the new - * sibling. When the compact_bundle job finishes compaction and - * fetches the node to replace the bundle, the node split is detected - * using the generation number, and the bundle is replaced in the new - * sibling as well. Note that the output of the compaction will - * contain tuples for both the node and its new sibling. - * - * o Leaf splits and compaction: - * - * 6. If a compaction is scheduled or in progress when a leaf split - * triggers, the leaf split will start its own compaction job on the - * bundle being compacted. When the compaction job initiates or - * finishes, it will detect the leaf split using the generation number - * of the leaf, and abort. - *----------------------------------------------------------------------------- - */ - -/* - *----------------------------------------------------------------------------- - * Trunk Nodes: splinter trunk_hdr{}: Disk-resident structure - * - * A trunk node, on pages of PAGE_TYPE_TRUNK type, consists of the following: - * - * Header - * meta data - * --------- - * Array of bundles - * When a collection of branches are flushed into a node, they are - * organized into a bundle. This bundle will be compacted into a - * single branch by a call to trunk_compact_bundle. Bundles are - * implemented as a collection of subbundles, each of which covers a - * range of branches. - * ---------- - * Array of subbundles - * A subbundle consists of the branches from a single ancestor (really - * that ancestor's pivot). During a flush, all the whole branches in - * the parent are collected into a subbundle in the child and any - * subbundles in the parent are copied to the child. - * - * Subbundles function properly in the current design, but are not - * used for anything. They are going to be used for routing filters. - * ---------- - * Array of pivots: Each node has a pivot corresponding to each - * child as well as an additional last pivot which contains - * an exclusive upper bound key for the node. Each pivot has - * a key which is an inclusive lower bound for the keys in - * its child node (as well as the btree - * rooted there). This means that the key for the 0th pivot - * is an inclusive lower bound for all keys in the node. - * Each pivot also has its own start_branch, which is used to - * determine which branches have tuples for that pivot (the - * range start_branch to end_branch). - * - * Each pivot's key is accessible via a call to trunk_get_pivot() and - * the remaining data is accessible via a call to - * trunk_get_pivot_data(). - * - * The number of pivots on a trunk page has two different limits: - * - A user-configurable static soft limit (fanout) - * - An internally determined hard limit (max_pivot_keys), based on - * the specified 'fanout' setting. - * - * When the soft limit is reached, it will cause the node to split the - * next time it is flushed into (see internal node splits above). - * Note that multiple pivots can be added to the parent of a leaf - * during a split and multiple splits could theoretically occur before - * the node is flushed into again, so the fanout limit may temporarily - * be exceeded by multiple pivots. - * - * The hard limit is the amount of physical space in the node which can - * be used for pivots and cannot be exceeded. - * - * Limits: The default fanout is 8 and the hard limit is 3x the fanout. Note - * that the additional last pivot (containing the exclusive upper - * bound to the node) counts towards the hard limit (because it uses - * physical space), but not the soft limit. - * ---------- - * Array of branches - * Whole branches: The branches from hdr->start_branch to - * hdr->start_frac_branch are "whole" branches, each of which is - * the output of a compaction or incorporation. - * Fractional branches: From hdr->start_frac_branch to hdr->end_branch - * are "fractional" branches that are part of bundles and are in - * the process of being compacted into whole branches. - * - * Logically, each whole branch and each bundle counts toward the - * number of branches in the node (or pivot), since each bundle - * represents a single branch after compaction. - * - * There are two limits on the number of branches in a node. The soft - * limit (max_branches_per_node) refers to logical branches (each - * whole branch and each bundle counts as a logical branch), and when - * there are more logical branches than the soft limit, the node is - * considered full and flushed until there are fewer branches than the - * soft limit. The hard limit (hard_max_branches_per_node) is the - * number of branches (whole and fractional) for which there is - * physical room in the node, and as a result cannot be exceeded. An - * attempt to flush _into_ a node which is at the hard limit will fail. - *----------------------------------------------------------------------------- - */ - - -/* - *----------------------------------------------------------------------------- - * structs - *----------------------------------------------------------------------------- - */ - /* *----------------------------------------------------------------------------- * Splinter Super Block: Disk-resident structure. @@ -418,146 +156,6 @@ typedef struct ONDISK trunk_super_block { checksum128 checksum; } trunk_super_block; -/* - * A subbundle is a collection of branches which originated in the same node. - * It is used to organize branches with their routing filters when they are - * flushed or otherwise moved or reorganized.
