Not setting this is kind of - silly, since that's the whole purpose of this lib, but it defaults - to `Infinity`. Setting it to a non-number or negative number will - throw a `TypeError`. Setting it to 0 makes it be `Infinity`. -* `maxAge` Maximum age in ms. Items are not pro-actively pruned out - as they age, but if you try to get an item that is too old, it'll - drop it and return undefined instead of giving it to you. - Setting this to a negative value will make everything seem old! - Setting it to a non-number will throw a `TypeError`. -* `length` Function that is used to calculate the length of stored - items. If you're storing strings or buffers, then you probably want - to do something like `function(n, key){return n.length}`. The default is - `function(){return 1}`, which is fine if you want to store `max` - like-sized things. The item is passed as the first argument, and - the key is passed as the second argumnet. -* `dispose` Function that is called on items when they are dropped - from the cache. This can be handy if you want to close file - descriptors or do other cleanup tasks when items are no longer - accessible. Called with `key, value`. It's called *before* - actually removing the item from the internal cache, so if you want - to immediately put it back in, you'll have to do that in a - `nextTick` or `setTimeout` callback or it won't do anything. -* `stale` By default, if you set a `maxAge`, it'll only actually pull - stale items out of the cache when you `get(key)`. (That is, it's - not pre-emptively doing a `setTimeout` or anything.) If you set - `stale:true`, it'll return the stale value before deleting it. If - you don't set this, then it'll return `undefined` when you try to - get a stale entry, as if it had already been deleted. -* `noDisposeOnSet` By default, if you set a `dispose()` method, then - it'll be called whenever a `set()` operation overwrites an existing - key. If you set this option, `dispose()` will only be called when a - key falls out of the cache, not when it is overwritten. -* `updateAgeOnGet` When using time-expiring entries with `maxAge`, - setting this to `true` will make each item's effective time update - to the current time whenever it is retrieved from cache, causing it - to not expire. (It can still fall out of cache based on recency of - use, of course.) - -## API - -* `set(key, value, maxAge)` -* `get(key) => value` - - Both of these will update the "recently used"-ness of the key. - They do what you think. `maxAge` is optional and overrides the - cache `maxAge` option if provided. - - If the key is not found, `get()` will return `undefined`. - - The key and val can be any value. - -* `peek(key)` - - Returns the key value (or `undefined` if not found) without - updating the "recently used"-ness of the key. - - (If you find yourself using this a lot, you *might* be using the - wrong sort of data structure, but there are some use cases where - it's handy.) - -* `del(key)` - - Deletes a key out of the cache. - -* `reset()` - - Clear the cache entirely, throwing away all values. - -* `has(key)` - - Check if a key is in the cache, without updating the recent-ness - or deleting it for being stale. - -* `forEach(function(value,key,cache), [thisp])` - - Just like `Array.prototype.forEach`. Iterates over all the keys - in the cache, in order of recent-ness. (Ie, more recently used - items are iterated over first.) - -* `rforEach(function(value,key,cache), [thisp])` - - The same as `cache.forEach(...)` but items are iterated over in - reverse order. (ie, less recently used items are iterated over - first.) - -* `keys()` - - Return an array of the keys in the cache. - -* `values()` - - Return an array of the values in the cache. - -* `length` - - Return total length of objects in cache taking into account - `length` options function. - -* `itemCount` - - Return total quantity of objects currently in cache. Note, that - `stale` (see options) items are returned as part of this item - count. - -* `dump()` - - Return an array of the cache entries ready for serialization and usage - with 'destinationCache.load(arr)`. - -* `load(cacheEntriesArray)` - - Loads another cache entries array, obtained with `sourceCache.dump()`, - into the cache. The destination cache is reset before loading new entries - -* `prune()` - - Manually iterates over the entire cache proactively pruning old entries diff --git a/deps/node/deps/npm/node_modules/cacache/node_modules/lru-cache/index.js b/deps/node/deps/npm/node_modules/cacache/node_modules/lru-cache/index.js deleted file mode 100644 index 573b6b85..00000000 --- a/deps/node/deps/npm/node_modules/cacache/node_modules/lru-cache/index.js +++ /dev/null @@ -1,334 +0,0 @@ -'use strict' - -// A linked list to keep track of recently-used-ness -const Yallist = require('yallist') - -const MAX = Symbol('max') -const LENGTH = Symbol('length') -const LENGTH_CALCULATOR = Symbol('lengthCalculator') -const ALLOW_STALE = Symbol('allowStale') -const MAX_AGE = Symbol('maxAge') -const DISPOSE = Symbol('dispose') -const NO_DISPOSE_ON_SET = Symbol('noDisposeOnSet') -const LRU_LIST = Symbol('lruList') -const CACHE = Symbol('cache') -const UPDATE_AGE_ON_GET = Symbol('updateAgeOnGet') - -const naiveLength = () => 1 - -// lruList is a yallist where the head is the youngest -// item, and the tail is the oldest. the list contains the Hit -// objects as the entries. -// Each Hit object has a reference to its Yallist.Node.
