SRI hashes follow the Subresource Integrity standard and support strings and objects compatible with [`ssri`](https://npm.im/ssri). - -* This change bumps the index version, which will invalidate all previous index entries. Content entries will remain intact, and existing caches will automatically reuse any content from before this breaking change. - -* `cacache.get.info()`, `cacache.ls()`, and `cacache.ls.stream()` will now return objects that looks like this: - -``` -{ - key: String, - integrity: '<algorithm>-<base64hash>', - path: ContentPath, - time: Date<ms>, - metadata: Any -} -``` - -* `opts.digest` and `opts.hashAlgorithm` are obsolete for any API calls that used them. - -* Anywhere `opts.digest` was accepted, `opts.integrity` is now an option. Any valid SRI hash is accepted here -- multiple hash entries will be resolved according to the standard: first, the "strongest" hash algorithm will be picked, and then each of the entries for that algorithm will be matched against the content. Content will be validated if *any* of the entries match (so, a single integrity string can be used for multiple "versions" of the same document/data). - -* `put.byDigest()`, `put.stream.byDigest`, `get.byDigest()` and `get.stream.byDigest()` now expect an SRI instead of a `digest` + `opts.hashAlgorithm` pairing. - -* `get.hasContent()` now expects an integrity hash instead of a digest. If content exists, it will return the specific single integrity hash that was found in the cache. - -* `verify()` has learned to handle integrity-based caches, and forgotten how to handle old-style cache indices due to the format change. - -* `cacache.rm.content()` now expects an integrity hash instead of a hex digest. - - - -<a name="6.3.0"></a> -# [6.3.0](https://github.com/zkat/cacache/compare/v6.2.0...v6.3.0) (2017-04-01) - - -### Bug Fixes -

Por ejemplo, el hacheo correspondiente al ejemplo -anterior sería: `sha1-X1UT+IIv2+UUWvM7ZNjZcNz5XG4=`. - -Puedes usar código así para generarlo por tu cuenta: - -```javascript -const crypto = require('crypto') -const algoritmo = 'sha512' -const datos = 'foobarbaz' - -const integrity = ( - algorithm + - '-' + - crypto.createHash(algoritmo).update(datos).digest('base64') -) -``` - -También puedes usar [`ssri`](https://npm.im/ssri) para deferir el trabajo a otra -librería que garantiza que todo esté correcto, pues maneja probablemente todas -las operaciones que tendrías que hacer con SRIs, incluyendo convirtiendo entre -hexadecimal y el formato SRI. - -#### <a name="verify"></a> `> cacache.verifica(cache, ops) -> Promise` - -Examina y arregla tu caché: - -* Limpia entradas inválidas, huérfanas y corrompidas -* Te deja filtrar cuales entradas retener, con tu propio filtro -* Reclama cualquier ficheros de contenido sin referencias en el índice -* Verifica integridad de todos los ficheros de contenido y remueve los malos -* Arregla permisos del caché -* Remieve el directorio `tmp` en el caché, y todo su contenido. - -Cuando termine, devuelve un objeto con varias estadísticas sobre el proceso de -verificación, por ejemplo la cantidad de espacio de disco reclamado, el número -de entradas válidas, número de entradas removidas, etc. - -##### Opciones - -* `ops.uid` - uid para asignarle al caché y su contenido -* `ops.gid` - gid para asignarle al caché y su contenido -* `ops.filter` - recibe una entrada como argumento.

You should be able to -copy `./locales/en.js` and `./locales/en.json` and fill them in. Translating the -`README.md` is a bit more work, but also appreciated if you get around to it. 👍🏼 - -#### <a name="ls"></a> `> cacache.ls(cache) -> Promise<Object>` - -Lists info for all entries currently in the cache as a single large object. Each -entry in the object will be keyed by the unique index key, with corresponding -[`get.info`](#get-info) objects as the values. - -##### Example - -```javascript -cacache.ls(cachePath).then(console.log) -// Output -{ - 'my-thing': { - key: 'my-thing', - integrity: 'sha512-BaSe64/EnCoDED+HAsh==' - path: '.testcache/content/deadbeef', // joined with `cachePath` - time: 12345698490, - size: 4023948, - metadata: { - name: 'blah', - version: '1.2.3', - description: 'this was once a package but now it is my-thing' - } - }, - 'other-thing': { - key: 'other-thing', - integrity: 'sha1-ANothER+hasH=', - path: '.testcache/content/bada55', - time: 11992309289, - size: 111112 - } -} -``` - -#### <a name="ls-stream"></a> `> cacache.ls.stream(cache) -> Readable` - -Lists info for all entries currently in the cache as a single large object. - -This works just like [`ls`](#ls), except [`get.info`](#get-info) entries are -returned as `'data'` events on the returned stream. - -##### Example - -```javascript -cacache.ls.stream(cachePath).on('data', console.log) -// Output -{ - key: 'my-thing', - integrity: 'sha512-BaSe64HaSh', - path: '.testcache/content/deadbeef', // joined with `cachePath` - time: 12345698490, - size: 13423, - metadata: { - name: 'blah', - version: '1.2.3', - description: 'this was once a package but now it is my-thing' - } -} - -{ - key: 'other-thing', - integrity: 'whirlpool-WoWSoMuchSupport', - path: '.testcache/content/bada55', - time: 11992309289, - size: 498023984029 -} - -{ - ... -} -``` - -#### <a name="get-data"></a> `> cacache.get(cache, key, [opts]) -> Promise({data, metadata, integrity})` - -Returns an object with the cached data, digest, and metadata identified by -`key`. The `data` property of this object will be a `Buffer` instance that -presumably holds some data that means something to you. I'm sure you know what -to do with it! cacache just won't care. - -`integrity` is a [Subresource -Integrity](#integrity) -string. That is, a string that can be used to verify `data`, which looks like -`<hash-algorithm>-<base64-integrity-hash>`. - -If there is no content identified by `key`, or if the locally-stored data does -not pass the validity checksum, the promise will be rejected. - -A sub-function, `get.byDigest` may be used for identical behavior, except lookup -will happen by integrity hash, bypassing the index entirely. This version of the -function *only* returns `data` itself, without any wrapper. - -##### Note - -This function loads the entire cache entry into memory before returning it. If -you're dealing with Very Large data, consider using [`get.stream`](#get-stream) -instead. - -##### Example - -```javascript -// Look up by key -cache.get(cachePath, 'my-thing').then(console.log) -// Output: -{ - metadata: { - thingName: 'my' - }, - integrity: 'sha512-BaSe64HaSh', - data: Buffer#<deadbeef>, - size: 9320 -} - -// Look up by digest -cache.get.byDigest(cachePath, 'sha512-BaSe64HaSh').then(console.log) -// Output: -Buffer#<deadbeef> -``` - -#### <a name="get-stream"></a> `> cacache.get.stream(cache, key, [opts]) -> Readable` - -Returns a [Readable Stream](https://nodejs.org/api/stream.html#stream_readable_streams) of the cached data identified by `key`. - -If there is no content identified by `key`, or if the locally-stored data does -not pass the validity checksum, an error will be emitted. - -`metadata` and `integrity` events will be emitted before the stream closes, if -you need to collect that extra data about the cached entry. - -A sub-function, `get.stream.byDigest` may be used for identical behavior, -except lookup will happen by integrity hash, bypassing the index entirely. This -version does not emit the `metadata` and `integrity` events at all. - -##### Example - -```javascript -// Look up by key -cache.get.stream( - cachePath, 'my-thing' -).on('metadata', metadata => { - console.log('metadata:', metadata) -}).on('integrity', integrity => { - console.log('integrity:', integrity) -}).pipe( - fs.createWriteStream('./x.tgz') -) -// Outputs: -metadata: { ... } -integrity: 'sha512-SoMeDIGest+64==' - -// Look up by digest -cache.get.stream.byDigest( - cachePath, 'sha512-SoMeDIGest+64==' -).pipe( - fs.createWriteStream('./x.tgz') -) -``` - -#### <a name="get-info"></a> `> cacache.get.info(cache, key) -> Promise` - -Looks up `key` in the cache index, returning information about the entry if -one exists. - -##### Fields - -* `key` - Key the entry was looked up under. Matches the `key` argument. -* `integrity` - [Subresource Integrity hash](#integrity) for the content this entry refers to. -* `path` - Filesystem path relative to `cache` argument where content is stored. -* `time` - Timestamp the entry was first added on. -* `metadata` - User-assigned metadata associated with the entry/content. - -##### Example - -```javascript -cacache.get.info(cachePath, 'my-thing').then(console.log) - -// Output -{ - key: 'my-thing', - integrity: 'sha256-MUSTVERIFY+ALL/THINGS==' - path: '.testcache/content/deadbeef', - time: 12345698490, - size: 849234, - metadata: { - name: 'blah', - version: '1.2.3', - description: 'this was once a package but now it is my-thing' - } -} -``` - -#### <a name="get-hasContent"></a> `> cacache.get.hasContent(cache, integrity) -> Promise` - -Looks up a [Subresource Integrity hash](#integrity) in the cache. If content -exists for this `integrity`, it will return an object, with the specific single integrity hash -that was found in `sri` key, and the size of the found content as `size`. If no content exists for this integrity, it will return `false`. - -##### Example - -```javascript -cacache.get.hasContent(cachePath, 'sha256-MUSTVERIFY+ALL/THINGS==').then(console.log) - -// Output -{ - sri: { - source: 'sha256-MUSTVERIFY+ALL/THINGS==', - algorithm: 'sha256', - digest: 'MUSTVERIFY+ALL/THINGS==', - options: [] - }, - size: 9001 -} - -cacache.get.hasContent(cachePath, 'sha521-NOT+IN/CACHE==').then(console.log) - -// Output -false -``` - -#### <a name="put-data"></a> `> cacache.put(cache, key, data, [opts]) -> Promise` - -Inserts data passed to it into the cache. The returned Promise resolves with a -digest (generated according to [`opts.algorithms`](#optsalgorithms)) after the -cache entry has been successfully written. - -##### Example - -```javascript -fetch( - 'https://registry.npmjs.org/cacache/-/cacache-1.0.0.tgz' -).then(data => { - return cacache.put(cachePath, 'registry.npmjs.org|cacache@1.0.0', data) -}).then(integrity => { - console.log('integrity hash is', integrity) -}) -``` - -#### <a name="put-stream"></a> `> cacache.put.stream(cache, key, [opts]) -> Writable` - -Returns a [Writable -Stream](https://nodejs.org/api/stream.html#stream_writable_streams) that inserts -data written to it into the cache. Emits an `integrity` event with the digest of -written contents when it succeeds. - -##### Example - -```javascript -request.get( - 'https://registry.npmjs.org/cacache/-/cacache-1.0.0.tgz' -).pipe( - cacache.put.stream( - cachePath, 'registry.npmjs.org|cacache@1.0.0' - ).on('integrity', d => console.log(`integrity digest is ${d}`)) -) -``` - -#### <a name="put-options"></a> `> cacache.put options` - -`cacache.put` functions have a number of options in common. - -##### `opts.metadata` - -Arbitrary metadata to be attached to the inserted key. - -##### `opts.size` - -If provided, the data stream will be verified to check that enough data was -passed through. If there's more or less data than expected, insertion will fail -with an `EBADSIZE` error. - -##### `opts.integrity` - -If present, the pre-calculated digest for the inserted content. If this option -if provided and does not match the post-insertion digest, insertion will fail -with an `EINTEGRITY` error. - -`algorithms` has no effect if this option is present. - -##### `opts.algorithms` - -Default: ['sha512'] - -Hashing algorithms to use when calculating the [subresource integrity -digest](#integrity) -for inserted data. Can use any algorithm listed in `crypto.getHashes()` or -`'omakase'`/`'お任せします'` to pick a random hash algorithm on each insertion. You -may also use any anagram of `'modnar'` to use this feature. - -Currently only supports one algorithm at a time (i.e., an array length of -exactly `1`). Has no effect if `opts.integrity` is present. - -##### `opts.uid`/`opts.gid` - -If provided, cacache will do its best to make sure any new files added to the -cache use this particular `uid`/`gid` combination. This can be used, -for example, to drop permissions when someone uses `sudo`, but cacache makes -no assumptions about your needs here. - -##### `opts.memoize` - -Default: null - -If provided, cacache will memoize the given cache insertion in memory, bypassing -any filesystem checks for that key or digest in future cache fetches. Nothing -will be written to the in-memory cache unless this option is explicitly truthy. - -If `opts.memoize` is an object or a `Map`-like (that is, an object with `get` -and `set` methods), it will be written to instead of the global memoization -cache. - -Reading from disk data can be forced by explicitly passing `memoize: false` to -the reader functions, but their default will be to read from memory. - -#### <a name="rm-all"></a> `> cacache.rm.all(cache) -> Promise` - -Clears the entire cache. Mainly by blowing away the cache directory itself. - -##### Example - -```javascript -cacache.rm.all(cachePath).then(() => { - console.log('THE APOCALYPSE IS UPON US 😱') -}) -``` - -#### <a name="rm-entry"></a> `> cacache.rm.entry(cache, key) -> Promise` - -Alias: `cacache.rm` - -Removes the index entry for `key`. Content will still be accessible if -requested directly by content address ([`get.stream.byDigest`](#get-stream)). - -To remove the content itself (which might still be used by other entries), use -[`rm.content`](#rm-content). Or, to safely vacuum any unused content, use -[`verify`](#verify). - -##### Example - -```javascript -cacache.rm.entry(cachePath, 'my-thing').then(() => { - console.log('I did not like it anyway') -}) -``` - -#### <a name="rm-content"></a> `> cacache.rm.content(cache, integrity) -> Promise` - -Removes the content identified by `integrity`. Any index entries referring to it -will not be usable again until the content is re-added to the cache with an -identical digest. - -##### Example - -```javascript -cacache.rm.content(cachePath, 'sha512-SoMeDIGest/IN+BaSE64==').then(() => { - console.log('data for my-thing is gone!') -}) -``` - -#### <a name="set-locale"></a> `> cacache.setLocale(locale)` - -Configure the language/locale used for messages and errors coming from cacache. -The list of available locales is in the `./locales` directory in the project -root. - -_Interested in contributing more languages! [Submit a PR](CONTRIBUTING.md)!_ - -#### <a name="clear-memoized"></a> `> cacache.clearMemoized()` - -Completely resets the in-memory entry cache. - -#### <a name="tmp-mkdir"></a> `> tmp.mkdir(cache, opts) -> Promise<Path>` - -Returns a unique temporary directory inside the cache's `tmp` dir. This -directory will use the same safe user assignment that all the other stuff use. - -Once the directory is made, it's the user's responsibility that all files within -are made according to the same `opts.gid`/`opts.uid` settings that would be -passed in. If not, you can ask cacache to do it for you by calling -[`tmp.fix()`](#tmp-fix), which will fix all tmp directory permissions. - -If you want automatic cleanup of this directory, use -[`tmp.withTmp()`](#with-tpm) - -##### Example - -```javascript -cacache.tmp.mkdir(cache).then(dir => { - fs.writeFile(path.join(dir, 'blablabla'), Buffer#<1234>, ...) -}) -``` - -#### <a name="with-tmp"></a> `> tmp.withTmp(cache, opts, cb) -> Promise` - -Creates a temporary directory with [`tmp.mkdir()`](#tmp-mkdir) and calls `cb` -with it. The created temporary directory will be removed when the return value -of `cb()` resolves -- that is, if you return a Promise from `cb()`, the tmp -directory will be automatically deleted once that promise completes. - -The same caveats apply when it comes to managing permissions for the tmp dir's -contents. - -##### Example - -```javascript -cacache.tmp.withTmp(cache, dir => { - return fs.writeFileAsync(path.join(dir, 'blablabla'), Buffer#<1234>, ...) -}).then(() => { - // `dir` no longer exists -}) -``` - -#### <a name="integrity"></a> Subresource Integrity Digests - -For content verification and addressing, cacache uses strings following the -[Subresource -Integrity spec](https://developer.mozilla.org/en-US/docs/Web/Security/Subresource_Integrity). -That is, any time cacache expects an `integrity` argument or option, it -should be in the format `<hashAlgorithm>-<base64-hash>`. - -One deviation from the current spec is that cacache will support any hash -algorithms supported by the underlying Node.js process. You can use -`crypto.getHashes()` to see which ones you can use. - -##### Generating Digests Yourself - -If you have an existing content shasum, they are generally formatted as a -hexadecimal string (that is, a sha1 would look like: -`5f5513f8822fdbe5145af33b64d8d970dcf95c6e`). In order to be compatible with -cacache, you'll need to convert this to an equivalent subresource integrity -string. For this example, the corresponding hash would be: -`sha1-X1UT+IIv2+UUWvM7ZNjZcNz5XG4=`. - -If you want to generate an integrity string yourself for existing data, you can -use something like this: - -```javascript -const crypto = require('crypto') -const hashAlgorithm = 'sha512' -const data = 'foobarbaz' - -const integrity = ( - hashAlgorithm + - '-' + - crypto.createHash(hashAlgorithm).update(data).digest('base64') -) -``` - -You can also use [`ssri`](https://npm.im/ssri) to have a richer set of functionality -around SRI strings, including generation, parsing, and translating from existing -hex-formatted strings. - -#### <a name="verify"></a> `> cacache.verify(cache, opts) -> Promise` - -Checks out and fixes up your cache: - -* Cleans up corrupted or invalid index entries. -* Custom entry filtering options. -* Garbage collects any content entries not referenced by the index. -* Checks integrity for all content entries and removes invalid content. -* Fixes cache ownership. -* Removes the `tmp` directory in the cache and all its contents. - -When it's done, it'll return an object with various stats about the verification -process, including amount of storage reclaimed, number of valid entries, number -of entries removed, etc. - -##### Options - -* `opts.uid` - uid to assign to cache and its contents -* `opts.gid` - gid to assign to cache and its contents -* `opts.filter` - receives a formatted entry. Return false to remove it. - Note: might be called more than once on the same entry. - -##### Example - -```sh -echo somegarbage >> $CACHEPATH/content/deadbeef -``` - -```javascript -cacache.verify(cachePath).then(stats => { - // deadbeef collected, because of invalid checksum. - console.log('cache is much nicer now! stats:', stats) -}) -``` - -#### <a name="verify-last-run"></a> `> cacache.verify.lastRun(cache) -> Promise` - -Returns a `Date` representing the last time `cacache.verify` was run on `cache`. - -##### Example - -```javascript -cacache.verify(cachePath).then(() => { - cacache.verify.lastRun(cachePath).then(lastTime => { - console.log('cacache.verify was last called on' + lastTime) - }) -}) -``` diff --git a/deps/npm/node_modules/npm-registry-fetch/node_modules/cacache/en.js b/deps/npm/node_modules/npm-registry-fetch/node_modules/cacache/en.js deleted file mode 100644 index a3db581c9f..0000000000 --- a/deps/npm/node_modules/npm-registry-fetch/node_modules/cacache/en.js +++ /dev/null @@ -1,3 +0,0 @@ -'use strict' - -module.exports = require('./locales/en.js') diff --git a/deps/npm/node_modules/npm-registry-fetch/node_modules/cacache/es.js b/deps/npm/node_modules/npm-registry-fetch/node_modules/cacache/es.js deleted file mode 100644 index 6282363c3b..0000000000 --- a/deps/npm/node_modules/npm-registry-fetch/node_modules/cacache/es.js +++ /dev/null @@ -1,3 +0,0 @@ -'use strict' - -module.exports = require('./locales/es.js') diff --git a/deps/npm/node_modules/npm-registry-fetch/node_modules/cacache/get.js b/deps/npm/node_modules/npm-registry-fetch/node_modules/cacache/get.js deleted file mode 100644 index 2bb3afa528..0000000000 --- a/deps/npm/node_modules/npm-registry-fetch/node_modules/cacache/get.js +++ /dev/null @@ -1,190 +0,0 @@ -'use strict' - -const BB = require('bluebird') - -const fs = require('fs') -const index = require('./lib/entry-index') -const memo = require('./lib/memoization') -const pipe = require('mississippi').pipe -const pipeline = require('mississippi').pipeline -const read = require('./lib/content/read') -const through = require('mississippi').through - -module.exports = function get (cache, key, opts) { - return getData(false, cache, key, opts) -} -module.exports.byDigest = function getByDigest (cache, digest, opts) { - return getData(true, cache, digest, opts) -} -function getData (byDigest, cache, key, opts) { - opts = opts || {} - const memoized = ( - byDigest - ? memo.get.byDigest(cache, key, opts) - : memo.get(cache, key, opts) - ) - if (memoized && opts.memoize !== false) { - return BB.resolve(byDigest ? memoized : { - metadata: memoized.entry.metadata, - data: memoized.data, - integrity: memoized.entry.integrity, - size: memoized.entry.size - }) - } - return ( - byDigest ?

To handle errors, use `miss.pipe` or handle the `error` event manually. - -#### original module - -`miss.concat` is provided by [`require('concat-stream')`](https://www.npmjs.com/package/concat-stream) - -#### example - -```js -var fs = require('fs') - -var readStream = fs.createReadStream('cat.png') -var concatStream = miss.concat(gotPicture) - -function callback (err) { - if (err) { - console.error(err) - process.exit(1) - } -} - -miss.pipe(readStream, concatStream, callback) - -function gotPicture(imageBuffer) { - // imageBuffer is all of `cat.png` as a node.js Buffer -} - -function handleError(err) { - // handle your error appropriately here, e.g.: - console.error(err) // print the error to STDERR - process.exit(1) // exit program with non-zero exit code -} -``` - -### finished - -##### `miss.finished(stream, cb)` - -Waits for `stream` to finish or error and then calls `cb` with `(err)`. `cb` will only be called once. `err` will be null if the stream finished without error, or else it will be populated with the error from the streams `error` event. - -This function is useful for simplifying stream handling code as it lets you handle success or error conditions in a single code path. It's used internally `miss.pipe`. - -#### original module - -`miss.finished` is provided by [`require('end-of-stream')`](https://www.npmjs.com/package/end-of-stream) - -#### example - -```js -var copySource = fs.createReadStream('./movie.mp4') -var copyDest = fs.createWriteStream('./movie-copy.mp4') - -copySource.pipe(copyDest) - -miss.finished(copyDest, function(err) { - if (err) return console.log('write failed', err) - console.log('write success') -}) -``` - -### parallel - -##### `miss.parallel(concurrency, each)` - -This works like `through` except you can process items in parallel, while still preserving the original input order. - -This is handy if you wanna take advantage of node's async I/O and process streams of items in batches. With this module you can build your very own streaming parallel job queue. - -Note that `miss.parallel` preserves input ordering, if you don't need that then you can use [through2-concurrent](https://github.com/almost/through2-concurrent) instead, which is very similar to this otherwise. - -#### original module - -`miss.parallel` is provided by [`require('parallel-transform')`](https://npmjs.org/parallel-transform) - -#### example - -This example fetches the GET HTTP headers for a stream of input URLs 5 at a time in parallel. - -```js -function getResponse (item, cb) { - var r = request(item.url) - r.on('error', function (err) { - cb(err) - }) - r.on('response', function (re) { - cb(null, {url: item.url, date: new Date(), status: re.statusCode, headers: re.headers}) - r.abort() - }) -} - -miss.pipe( - fs.createReadStream('./urls.txt'), // one url per line - split(), - miss.parallel(5, getResponse), - miss.through(function (row, enc, next) { - console.log(JSON.stringify(row)) - next() - }) -) -``` - -## see also - -- [substack/stream-handbook](https://github.com/substack/stream-handbook) -- [nodejs.org/api/stream.html](https://nodejs.org/api/stream.html) -- [awesome-nodejs-streams](https://github.com/thejmazz/awesome-nodejs-streams) -
