Mercurial: Changelog

verify: allow suppressing warnings about extra files The verifier issues warnings when the set of files in .hg/store doesn't align with the set of files that are advertised via repo.file(f).files() for all files seen in ctx.files() changelog traversal. This logic is reasonable for a default implementation. But some stores may have extra files whose presence is harmless. Or those stores may not have the same transaction rollback semantics that unlink files as other stores. This commit adds support for disabling the warning for orphaned files. The simple store extension has been taught to set this flag. Differential Revision: https://phab.mercurial-scm.org/D3097

tests: conditionalize tests for various repo features Working my down the long tail of test failures due to the simple store. We're now down to 38 failures with the simple store. Differential Revision: https://phab.mercurial-scm.org/D3096

simplestore: use a custom store for the simple store repo Before, we used the default store, which was based on fncache and dotencode. After attempting to port tests to work with the simple store, I realized that fncache was more trouble than it is worth. This commit implements a proper store type for the simple repo - one that isn't based off fncache. This causes a number of new test failures because of tests expecting the full fncache store filename encoding. I may extend the store format in a subsequent commit to take the filename encoding parts of fncache that we can take (basically everything except hash encoding, since that isn't reversible). But for now, let's use encoded store. As part of this, we implement proper requirements support for repos created with the simple store. This should have been done from the beginning, as a requirement is needed to lock out clients that don't understand a storage format. A new hghave feature advertising the presence of fncache in repos has been added. Most tests touching the fncache are now conditional on that feature. Other tests have added the optional repo requirement to output. Differential Revision: https://phab.mercurial-scm.org/D3095

wireproto: allow direct stream processing for unbundle Introduce a new option server.streamunbundle which starts a transaction immediately to apply a bundle instead of writing it to a temporary file first. This side steps the need for a large tmp directory at the cost of preventing concurrent pushes. This is a reasonable trade-off for many setups as concurrent pushes for the main branch at least are disallowed anyway. The option defaults to off to preserve existing behavior. Change the wireproto interface to provide a generator for reading the payload and make callers responsible for consuming all data. Differential Revision: https://phab.mercurial-scm.org/D2470
