copies: fix an incorrect comment in graftcopies() from recent D9802 I don't think the bit about creating a merge in the filelog was correct. Or at least I couldn't find a case where it happened. Differential Revision: https://phab.mercurial-scm.org/D9899

narrow: delete a stale TODO about not sending groups the client already has 2c5835b4246b changed the changegroup generation to not send treemanifests for directories the client had before widening. As that commit mentions, we had already stopped before that commit to send the changelog and filelogs for files the client already had. Differential Revision: https://phab.mercurial-scm.org/D9898

copies: add an devel option to trace all files Filelog based copy tracing only trace copy for file that have been added. This is a trade off between skipping some rare copy case in exchange for avoiding atrocious-to-the-point-of-unusable performance. The changeset centric copy tracing does not need this trade off and naturally trace all copy, include the one involving non-new files. In order to ease the comparison from both algorithm, we add a small devel option to trace copy for all files in the target revisions. Differential Revision: https://phab.mercurial-scm.org/D9796

revlog: prepare pure parser for being overloaded The current class uses module-level variables which don't allow for reusing the current logic for a slightly different revlog version. Differential Revision: https://phab.mercurial-scm.org/D9903

revlog: use a less probable revlog version for backwards compatibility This allows us to define a usable v2. Differential Revision: https://phab.mercurial-scm.org/D9902

convert: option to set date and time for svn commits Converting to subversion repository is not preserving original commit dates as it may break some subversion functionality if commit dates are not monotonically increasing. This patch adds `convert.svn.dangerous-set-commit-dates` configuration option to change this behaviour and enable commit dates convertion for those who want to take risks. Subversion always uses commit dates with UTC timezone, so only timestamps are used. Test `test-convert-svn-sink.t` uses `svnxml.py` script to dump history of svn repositories. Atm the script is not printing `date` field from svn log. This patch changes this to allow checks on correctness of date and time convertion. Documentation is updated. Additional test case is added to test commit dates convertion. Differential Revision: https://phab.mercurial-scm.org/D9721

copies: simplify the conditional for _filter's case 3 The conditional is much simpler and the test are actually happier. This clarification of the conditional will also be necessary to properly support tracing more renames in a coming changeset. Differential Revision: https://phab.mercurial-scm.org/D9795
