status: add test that shows that the Rust implementation has a bug Differential Revision: https://phab.mercurial-scm.org/D9976

tweak-default: no longer enable the experimental return code The change is quite new and undocumented (since it is experimental) so it seems premature to make it available in tweak default. In addition, I am not sure the new return code are frozen yet (eg: some of the initial feedback have not been incorporated). Before the release I doubled check (probably with Martin) that they were not enabled by default and got replied that they were only enabled in the tests. Have I been aware that they have been also enabled in tweak default I would I have lobbied to delay that. I discovered they were in tweak default from users feedback. They found it an unpleasant and unexpected surprise of 5.7. So I suggest we no enable enable this experimental feature for Mercurial 5.7 and revisit this later, when the feature will be more mature.

wireprotopeer: clarify some variable names now that we allow snake_case "encargsorres" is hard to parse ("encarg sorres" sounds like it might be Spanish to me, and indeed Google Translate tells me that it's Catalan for "order sands").

bundle2: print "error:abort" message to stderr instead of stdout It seems like the server's message is something you'd like to see even with `--quiet`. It's clearly part of the error. Differential Revision: https://phab.mercurial-scm.org/D9954

narrow: add --no-backup option for narrowing Most of our users at Google use Mercurial on a file system that keeps backups of previous versions of all files, including those in `.hg/`. They therefore don't need a separate backup in the file system when narrowing their repo (which they typically do by running `hg tracked --auto-remove-includes`). Backups can be very slow. `hg strip` already has a `--no-backup` option. This patch adds the same option to `hg tracked --removeinclude/--addexclude`. Differential Revision: https://phab.mercurial-scm.org/D9951

debugdiscovery: add flags to run discovery on subsets of the local repo Generating new repository using strip of local clone is very expensive for large repositories. And such large repository are the most likely to requires debugging around discovery. So we add a simple way to run discovery using provided sets of heads. Differential Revision: https://phab.mercurial-scm.org/D9945

cmdutil: add a missing byte prefix to string introduce in 976b26bdd0d8 The change is missing a the `b'foo'` prefix to make it a bytestring. This lead to a traceback in some third party extension. It is unclear to me why the Mercurial test pass without it. Differential Revision: https://phab.mercurial-scm.org/D9974

relnote: remove the reference to `debugstrip` The `debug` namespace is not intended for end user and advertising it is a path to confusion and trouble. I think we should wait for the `admin` namespace to exists and the command to be available as `admin--strip` before we advertise it. Differential Revision: https://phab.mercurial-scm.org/D9817

upgrade: implement partial upgrade for upgrading persistent-nodemap Upgrading repositories to use persistent nodemap should be fast and easy as it requires only two things: 1) Updating the requirements 2) Writing a persistent-nodemap on disk For both of the steps above, we don't need to edit existing revlogs. This patch makes upgrade only do the above mentioned two steps if we are only upgarding to use persistent-nodemap feature. Since `nodemap.persist_nodemap()` assumes that there exists a nodemap file for the given revlog if we are trying to call it, this patch adds `force` argument to create a file if does not exist which is true in our upgrade case. The test changes demonstrate that we no longer write nodemap files for manifest after upgrade which I think is desirable. Differential Revision: https://phab.mercurial-scm.org/D9936

nodemap: make `_persist_nodemap` a public function I will like to have a utility function using which we can directly write out nodemap for a repository without going through the recloning process. This function seems like the one containing important pieces for that. Let's make it public. Differential Revision: https://phab.mercurial-scm.org/D9932

largefiles: properly pass kwargs into url.open The url.open function has acquired a lot of kwargs over the years. When running `hg import http://example.com/hg/diff/1`, since at least a708e1e4d7a8 in March, 2018, the calling sites for url.open try to pass a `sendaccept` parameter that largefiles' override doesn't accept. Currently that stack traces something like this: Traceback (most recent call last): File "/tmp/hgtests.sv744r5t/install/bin/hg", line 59, in <module> dispatch.run() File "/tmp/hgtests.sv744r5t/install/lib/python/mercurial/dispatch.py", line 143, in run status = dispatch(req) File "/tmp/hgtests.sv744r5t/install/lib/python/mercurial/dispatch.py", line 245, in dispatch status = _rundispatch(req) File "/tmp/hgtests.sv744r5t/install/lib/python/mercurial/dispatch.py", line 289, in _rundispatch ret = _runcatch(req) or 0 File "/tmp/hgtests.sv744r5t/install/lib/python/mercurial/dispatch.py", line 465, in _runcatch return _callcatch(ui, _runcatchfunc) File "/tmp/hgtests.sv744r5t/install/lib/python/mercurial/dispatch.py", line 475, in _callcatch return scmutil.callcatch(ui, func) File "/tmp/hgtests.sv744r5t/install/lib/python/mercurial/scmutil.py", line 155, in callcatch return func() File "/tmp/hgtests.sv744r5t/install/lib/python/mercurial/dispatch.py", line 455, in _runcatchfunc return _dispatch(req) File "/tmp/hgtests.sv744r5t/install/lib/python/mercurial/dispatch.py", line 1259, in _dispatch lui, repo, cmd, fullargs, ui, options, d, cmdpats, cmdoptions File "/tmp/hgtests.sv744r5t/install/lib/python/mercurial/dispatch.py", line 913, in runcommand ret = _runcommand(ui, options, cmd, d) File "/tmp/hgtests.sv744r5t/install/lib/python/mercurial/dispatch.py", line 1270, in _runcommand return cmdfunc() File "/tmp/hgtests.sv744r5t/install/lib/python/mercurial/dispatch.py", line 1256, in <lambda> d = lambda: util.checksignature(func)(ui, *args, **strcmdopt) File "/tmp/hgtests.sv744r5t/install/lib/python/mercurial/util.py", line 1867, in check return func(*args, **kwargs) File "/tmp/hgtests.sv744r5t/install/lib/python/mercurial/commands.py", line 4184, in import_ patchfile = hg.openpath(ui, patchurl, sendaccept=False) File "/tmp/hgtests.sv744r5t/install/lib/python/mercurial/hg.py", line 181, in openpath return url.open(ui, path, sendaccept=sendaccept) TypeError: openlargefile() got an unexpected keyword argument 'sendaccept' So, just accept and pass along any kwargs of the overridden function.
