6You are in 'detached HEAD' state. You can look around, make experimental

7changes and commit them, and you can discard any commits you make in this

8state without impacting any branches by switching back to a branch.

10If you want to create a new branch to retain commits you create, you may

11do so (now or later) by using -c with the switch command. Example:

13 git switch -c <new-branch-name>

15Or undo this operation with:

17 git switch -

19Turn off this advice by setting config variable advice.detachedHead to false

194[info] FetchReportingTests:

195[info] - Plain values have no rounds of execution

196[info] - Single fetches are executed in one round

197[info] - Single fetches are executed in one round per binding in a for comprehension

198[info] - Single fetches for different data sources are executed in multiple rounds if they are in a for comprehension

199[info] - Single fetches combined with cartesian are run in one round

200[info] - Single fetches combined with traverse are run in one round

201[info] - Single fetches combined with Fetch.batchAll are run in one round

202[info] - The product of two fetches from the same data source implies batching

203[info] - The product of concurrent fetches of the same type implies everything fetched in batches

204[info] FetchSyntaxTests:

205[info] - `fetch` syntax allows lifting of any value to the context of a fetch

206[info] - `fetch` syntax allows lifting of any `Throwable` as a failure on a fetch

207[info] - `batchAll` syntax allows batching sequences of fetches and is equivalent to Fetch.batchAll

208[info] FetchTests:

209[info] - We can lift plain values to Fetch

210[info] - We can lift values which have a Data Source to Fetch

211[info] - We can map over Fetch values

212[info] - We can use fetch inside a for comprehension

213[info] - We can mix data sources

214[info] - We can use Fetch as a cartesian

215[info] - We can use Fetch as an applicative

216[info] - We can traverse over a list with a Fetch for each element

217[info] - We can depend on previous computations of Fetch values

218[info] - We can collect a list of Fetch into one

219[info] - We can collect a list of Fetches with heterogeneous sources

220[info] - We can collect the results of a traversal

221[info] - Monadic bind implies sequential execution

222[info] - Traversals are implicitly batched

223[info] - Sequencing is implicitly batched

224[info] - Identities are deduped when batched

225[info] - The product of two fetches implies parallel fetching

226[info] - Concurrent fetching calls batches only when it can

227[info] - Concurrent fetching performs requests to multiple data sources in parallel

228[info] - The product of concurrent fetches implies everything fetched concurrently

229[info] - The product of concurrent fetches of the same type implies everything fetched in a single batch

230[info] - Every level of joined concurrent fetches is combined and batched

231[info] - Every level of batched, concurrent fetches is batched

232[info] - The product of two fetches from the same data source implies batching

233[info] - Sequenced fetches are run concurrently

234[info] - Manually batched fetches are run concurrently

235[info] - Sequenced fetches are deduped

236[info] - Manually batched fetches are deduped

237[info] - Traversals are batched

238[info] - Duplicated sources are only fetched once

239[info] - Sources that can be fetched concurrently inside a for comprehension will automatically be concurrent

240[info] - Sources that are manually batched will be fetched concurrently

241[info] - Pure Fetches allow to explore further in the Fetch

242[info] - Elements are cached and thus not fetched more than once

243[info] - Batched elements are cached and thus not fetched more than once

244[info] - Elements that are cached won't be fetched

245[info] - Fetch#run accepts a cache as the second (optional) parameter

246[info] - Fetch#runCache accepts a cache as the second (optional) parameter

247[info] - Fetch#runCache works without the optional cache parameter

248[info] - We can use a custom cache that discards elements

249[info] - We can use a custom cache that discards elements together with concurrent fetches

250[info] - Data sources with errors throw fetch failures

251[info] - Data sources with errors throw fetch failures that can be handled

252[info] - Data sources with errors won't fail if they're cached

253[info] - We can lift errors to Fetch

254[info] - We can lift handle and recover from errors in Fetch

255[info] - If a fetch fails in the left hand of a product the product will fail

256[info] - If a fetch fails in the right hand of a product the product will fail

257[info] - If there is a missing identity in the left hand of a product the product will fail

258[info] - If there is a missing identity in the right hand of a product the product will fail

259[info] - If there are multiple failing identities the fetch will fail

260[info] - We can run optional fetches

261[info] - We can run optional fetches with Fetch.batchAll

262[info] - We can run optional fetches with other data sources

263[info] - We can make fetches that depend on optional fetch results when they aren't defined

264[info] - We can make fetches that depend on optional fetch results when they are defined

265[info] - We can lift IO actions into Fetch

266[info] - A failed IO action lifted into Fetch will cause a Fetch to fail

267[info] - A IO action can be combined with data fetches

268[info] - We can lift Concurrent actions into Fetch

269[info] - A failed Concurrent action lifted into Fetch will cause a Fetch to fail

270[info] - A Concurrent action can be combined with data fetches

271[info] FetchAsyncQueryTests:

272[info] - We can interpret an async fetch into an IO

273[info] - We can combine several async data sources and interpret a fetch into an IO

274[info] - We can use combinators in a for comprehension and interpret a fetch from async sources into an IO

275[info] - We can use combinators and multiple sources in a for comprehension and interpret a fetch from async sources into an IO

276[info] FetchBatchingTests:

277[info] - A large fetch to a datasource with a maximum batch size is split and executed in sequence

278[info] - A large fetch to a datasource with a maximum batch size is split and executed in parallel

279[info] - Fetches to datasources with a maximum batch size should be split and executed in parallel and sequentially when using productR

280[info] - Fetches to datasources with a maximum batch size should be split and executed in parallel and sequentially when using productL

281[info] - A large (many) fetch to a datasource with a maximum batch size is split and executed in sequence

282[info] - A large (many) fetch to a datasource with a maximum batch size is split and executed in parallel

283[info] - Very deep fetches don't overflow stack or heap

284[info] - Fetches produced across unrelated fetches to a DataSource that is NOT batched across fetch executions should NOT be bundled together

285[info] - Fetches produced across unrelated fetches to a DataSource that is batched across fetch executions should be bundled together
