helptext: update first hg version when share-safe will be released I authored the patch which added the helptext before 5.6 release hoping that my patches will make it. However they didn't before the release and were pushed after the release only. Differential Revision: https://phab.mercurial-scm.org/D9410

share: show warning if share is outdated while source supports share-safe Previous patches in the series and some which are already committed implements share safe functionality where config and requirements will be shared too. Rolling this feature has a problem that existing shares may never upgrade as they will never learn about the new config. To help the transition, we show a warning message if the share source supports share-safe mechanism. This provides the source repo ability to upgrade and pass on the message to shares that you should reshare and upgrade too. Differential Revision: https://phab.mercurial-scm.org/D9369

upgrade: add support to downgrade share safe mode In previous patch we added support to upgrade current repository to use share safe mode. This patch adds support to downgrade to remove share-safe mode. Differential Revision: https://phab.mercurial-scm.org/D9358

upgrade: add support for experimental safe share mode Recently we introduce the share-safe functionality which makes shares share requirements and config of share source. This patch adds support to `debugupgraderepo` command to upgrade repository to share-safe mode when `format.exp-share-safe` config is enabled.

chgserver: catch RepoError while loading configuration Recent share safe work introduced functionality to read share source config file on dispatch. This can result in RepoError while reading config file as the shared source might not be present. `test-share.t#safe` was failing with chg earlier because of this.

registrar: clarify the documentation about some byte strings being required I *thought* these needed to be byte strings, but didn't remember and had to search out examples. Differential Revision: https://phab.mercurial-scm.org/D9489

match: skip walking up the directory hierarchy if the number of pats are small Previously, we would receive a path like abc/def/ghi and "walk up" the directory hierarchy, checking abc/def, abc, and `b''` to see if they were in the set of prefixes that this matcher covered. We did this indiscriminately - we generated all of these paths even if the set of prefixes the matcher covered was completely empty, which is the case for a lot of repos at my company (the narrow matcher we use is usually non-recursive). This brings the time for a rebase in one of my repos from 12.20s to 10.87s. In this particular repo, this is entirely due to the `len(prefix_set) == 0` check, as I do not have any recursive patterns in the narrowspec.

upgrade: add an explicite --filelogs arguments This make it possible to select no revlog for upgrade, which is useful for some upgrade target or in some specific cases (eg: persistent-nodemap or share-safe update). Differential Revision: https://phab.mercurial-scm.org/D9468

rhg: add a test for --rev with a hex changeset ID And fix error message formatting Differential Revision: https://phab.mercurial-scm.org/D9478

upgrade: move optimisation to something more declarative This is not great yet, but still better than the previous state. This get use one step closer to having all the possible "actions" clearly declared and moved in a dedicated module. Differential Revision: https://phab.mercurial-scm.org/D9475

upgrade: capitalize the `deficiency` constant I am reworking this code and moving to the current naming scheme help readability. Differential Revision: https://phab.mercurial-scm.org/D9474

tests: set old git default branch name for compatibility Git's default branch name has changed on my machine (from "master" to "main"). Let's set the old name in our tests so we're compatible with both defaults (and maybe still compatible with Git versions that don't know about the config option).

heptapod-ci: automatically refresh existing phabricator Diff on push If a changeset have been submitted to Phabricator and a new version is pushed to heptapod, we should refresh the state on Phabricator. If we do not do this, they are a risk of an older version being applied from Phabricator. In this situation content-divergence will be (rightfully) detected by evolution. We only refresh the Diff if the test pass, to avoid updating Phabricator with broken content. Differential Revision: https://phab.mercurial-scm.org/D9451
