= Mercurial 6.9rc0 = /!\ These are release notes for a release candidate version. Any and all points can be reverted before the final release. == New Features == * exchange: improve computation of relevant markers for large repos * Add a Rust fast-path to speed up update (also for `clone`) from null (up to 4x faster) * Introduced a new rev-branch-cache version (v2) that is mmap-resistant * The branchmap's performance was improved * Improved the performance of the fix for issue6528 * clonebundles: allow manifest to specify sha256 digest of bundles * merge: improve working-copy mtime race handling * profiling: add a py-spy profiling backend * revlog: use an explicit config option to enable mmap usage for index * revlog: use mmap by default is pre-population is available * mmap: populate the mapping by default * mmap: populate mapping in a background thread == Experimental features == * merge: add a config to allow conflict-free merge of changes on adjacent lines == Bug Fixes == * `config.server.validate` now also works on narrowed repositories * convert: fix various leaked file descriptors * stream: prefer keeping an open file handle to volatile file instead of copy * dummysmtpd: fix EOF handling on newer versions of OpenSSL * cext: correct the argument handling of `b85encode()` * branchmap-v3: make sure we write the cache after detecting pure-topo mode * rust: apply clippy lints * copies: make sure deleted copy info do not overwriting unrelated ones * rebase: don't call rewriteutil.precheck() with to-be-skipped commits * phabricator: correct the default value of `phabhunk.corpus` * linelog: correct the default value of `annotateresult.lines` * largefiles: avoid a potentially undefined variable in exception case * httppeer: move a variable to avoid a bad reference before assignment warning * httppeer: avoid another bad reference before assignment warning * tests: use packaging from setuptools instead of deprecated distutils * manifest: type and fix unhexlify * manifest: align some vfs option access on the fact we might not have options * scmutils: read the requires file before writing to avoid unnecessary rewrite * debugsparse: stop taking the store lock * sparse: reliably avoid writing to store without a lock * largefiles: sync up `largefilesdirstate` methods with `dirstate` base class * shelve: raise an error when loading a corrupt state file in an impossible case * monotone: replace %s interpolation with appropriate numeric specifiers * shelve: consistently convert exception to bytes via `stringutil.forcebytestr` * remotefilelog: honor the `--format` arg of the `debugindex` command * remotefilelog: adapt the `debugindex` command to past API changes * run-tests: add color to the progress output * archive: defer opening the output until a file is matched * help: add :config-doc:`section.key` shorthand to insert documentation * censor: document the censor.policy option (issue6909) * rust-revlog: don't try to open the data file if the index is empty * bundlerepo: fix mismatches with repository and revlog classes * revlog: make `clearcaches()` signature consistent with ManifestRevlog * unionrepo: fix mismatches with revlog classes * keepalive: fix a signature mismatch for a http.client.HTTPResponse subclass * lfs: fix various signature mismatches for vfs subclasses * store: fix a signature mismatch for a vfs subclass * util: avoid a leaked file descriptor in `util.makelock()` exceptional case * statichttprepo: fix `httprangereader.read()` for py3 * util: make `mmapread()` work on Windows again * mdiff: tweak calls into `bdiff.fixws` to match its type hints * base85: avoid a spurious use-before-initialized warning in `pure` module * install: static data moved from setup.py to pyproject.toml * upgrade: disable using the parallel workers optimization on macOS * doc: generate separate commands/topics/extension pages * extdiff: don't run gui programs when in a cli-only environment * clonebundles: stop shell quoting `HGCB_BUNDLE_BASENAME` environment variable * rev-branch-cache: disable mmapping by default on Windows == Backwards Compatibility Changes == * This release drops support for Python 3.6 and 3.7. == Internal API Changes == * manifest: deprecated readdelta and readfast == Miscellaneous == * http: reuse Python's implementation of read/readline/readinto * http: use urllib's cookie handler * rev-branch-cache: schedule a write of the "v2" format if we read from "v1" * rev-branch-cache: have debugupdatecache warm rbc too * rev-branch-cache: reenable memory mapping of the revision data * debugwireproto: redo logging to also work for https * rust: use `.cargo/config.toml` instead of `.cargo/config` * A whole bunch of typing improvements, which in turn found many bugs * Test suite improvements * Various packaging improvements
