clonebundles: move a bundle of clone bundle related code to a new module In the process on general clone bundle automatically, we need to make some function available more widely. This is a good opportunity to extract a significant amount of code from `mercurial.exchange` into a new `mercurial.bundlecaches`. This make `mercurial.exchange` move under the 3K line range (hooray…). The module is called `bundlecaches` because I expect it to be eventually useful for more than just clone bundle (like pull bunbles). Differential Revision: https://phab.mercurial-scm.org/D9208

config: add a .hg/hgrc-not-shared which won't be shared in share-safe mode Previous patches add a safe mode for sharing repositories which involve sharing of source requirements and config files. In certain situations we might need to add a config to source repository which we does not want to share. For this, we add a `.hg/hgrc-not-shared` which won't be shared. This also adds a `--non-shared` flag to `hg config` command to see the non-shared config. Differential Revision: https://phab.mercurial-scm.org/D8673

dispatch: load shared source repository config in share-safe mode It seems to me now that there are two steps when config is loaded: 1) on dispatch 2) repository object creation Recent patches added functionality that there can be shares in share-safe mode where config of the source repository is shared with the the shares. However we missed adding logic to read the source config on dispatch. This leads to extensions not being loaded on dispatch and hence extensions command not being recognized. This patch fixes it by reading the shared source config on dispatch. Differential Revision: https://phab.mercurial-scm.org/D9047

tests: add test showing broken extension loading in case of share-safe When we are using share-safe and loading source repository config, we are still not loading the extensions which are enabled in the source repository. This patch demonstrates the bug. Meanwhile it also shows how unreliable `hg debugextensions` is. Differential Revision: https://phab.mercurial-scm.org/D9046

dirstate-tree: simplify the control flow in the Node.insert method But explicitly with the special case early, laying out the various case become simpler. (The initial motivation was to make some future lifetime error simpler). Differential Revision: https://phab.mercurial-scm.org/D9203

revlog: use LRU for the chain cache For a large repository, this reduces the number of filelog instances and associated data a lot. For a 1% speed penalty, it reduces peak RSS by 20% for the full NetBSD test repository. Differential Revision: https://phab.mercurial-scm.org/D9235

tests: add notes about broken `hg log --follow <file>` with copies in extras I also removed some unnecessary `#if no-changeset` where the `#else` was the same :P Differential Revision: https://phab.mercurial-scm.org/D9204

config: move message about leading spaces in config to config.py When the config parser raises a ParseError, it uses the line that failed to parse as the error message. It doesn't currently tell the user anything about why it failed to parse. b13b99d39a46 (config: highlight parse error caused by leading spaces (issue3214), 2014-03-16) added a checked based on the error *message* having leading spaces. That has worked fine because only the config parser uses the line itself as error message (I think the revset and fileset parsers use more user-friendly proper messages). It still feels like a hack. Let's make the config parser give a useful message about leading whitespace instead. We should ideally follow up with more useful messages for other parse errors in config files.

errors: name arguments to ParseError constructor As with similar previous patches, this is to improve readability. Differential Revision: https://phab.mercurial-scm.org/D9240

split: use default one-line summary Differential Revision: https://phab.mercurial-scm.org/D9255

phabsend: use default one-line summary This means that the `phabricator.node` and `phabricator.desc` color configs will no longer be respected, but `log.changeset` and `log.desc` will be respected instead. Differential Revision: https://phab.mercurial-scm.org/D9254

rebase: change and standarize template for rebase's one-line summary This removes the default template in rebase and switches to a centrally defined template. I've simplified it a bit to avoid the conditional parenthesis. I've also added labels so the different parts can be easily colored. The template is somewhat similar to what we've used internally at Google for a few years. I'm happy to change the template if others have opinions. Should we reuse the `color.log.` names as I have?

rebase: make summary template configurable, with default to shared template Differential Revision: https://phab.mercurial-scm.org/D9251

rebase: use hard-coded template for one-line commit description This is to prepare for making making the one-line summary customizable. The template ended up pretty complicated because of the conditional output of "(<bookmarks etc>)". Maybe we can simplify the template later.

config: rename ui.graphnodetemplate to command-templates.graphnode Differential Revision: https://phab.mercurial-scm.org/D9246

config: add a new [command-templates] section for templates defined by hg The existing `[templates]` section lets the user define their own keys and then refer to them on the command line with `-T`. There are many cases where hg wants to use a user-defined template with a given name, such as `ui.logtemplate` and `ui.mergemarkertemplate`. This patch starts moving such configs in a common section by moving `ui.logtemplate` to `command-templates.log` (with an alias from the old name, of course).

rebase: clear merge state when aborting in-memory merge on dirty working copy Differential Revision: https://phab.mercurial-scm.org/D9509

tests: show that in-memory rebase leaves state when working copy is dirty When in-memory rebase falls back to on-disk rebase, it checks if the working copy is dirty. If it is, it aborts the rebase. However, it leaves the rebase state on disk. I broke it in feffeb18d412 (rebase: teach in-memory rebase to not restart with on-disk rebase on conflict, 2020-09-18).

extensions: avoid a crash when the version isn't properly byteified on py3 We already force bytestr on the `testedwith` and `buglink` attributes in dispatch.py when generating a bug report with a similar comment about not every extension being ported to py3. We should do the same here, so the function can be properly typed. Differential Revision: https://phab.mercurial-scm.org/D9433
