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] FetchAsyncQueryTests:

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

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

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

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

199[info] FetchSyntaxTests:

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

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

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

203[info] FetchReportingTests:

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

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

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

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

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

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

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

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

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

213[info] FetchTests:

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

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

218[info] - We can mix data sources

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

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

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

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

226[info] - Monadic bind implies sequential execution

227[info] - Traversals are implicitly batched

228[info] - Sequencing is implicitly batched

229[info] - Identities are deduped when batched

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

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

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

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

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

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

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

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

238[info] - Sequenced fetches are run concurrently

239[info] - Manually batched fetches are run concurrently

240[info] - Sequenced fetches are deduped

241[info] - Manually batched fetches are deduped

242[info] - Traversals are batched

243[info] - Duplicated sources are only fetched once

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

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

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

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

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

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

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

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

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

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

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

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

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

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

258[info] - We can lift errors to Fetch

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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
