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] FetchReportingTests:

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

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

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

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

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

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

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

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

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

209[info] FetchTests:

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

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

212[info] - We can map over Fetch values

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

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

222[info] - Monadic bind implies sequential execution

223[info] - Traversals are implicitly batched

224[info] - Sequencing is implicitly batched

225[info] - Identities are deduped when batched

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

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

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

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

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

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

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

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

234[info] - Sequenced fetches are run concurrently

235[info] - Manually batched fetches are run concurrently

236[info] - Sequenced fetches are deduped

237[info] - Manually batched fetches are deduped

238[info] - Traversals are batched

239[info] - Duplicated sources are only fetched once

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

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

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

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

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

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

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

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

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

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

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

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

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

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

254[info] - We can lift errors to Fetch

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

272[info] FetchSyntaxTests:

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

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

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

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
