tests: demonstrate that hgweb renders "pruned" that minirst.format() returns Notice at the bottom of the help text there's "windows". It's a section that is in the original help text, but was pruned (because hgweb didn't ask for it).

rebase: avoid RevlogError when computing obsoletenotrebased (issue5907) The key to reproducing this seems to be missing an obsolete node that is not an ancestor of the destination.

rebase: prioritize indicating an interrupted rebase over update (issue5838) This should also cover the transplant extension, and any other non clearable states.

tests: demonstrate inconsistent messaging around interrupted rebases

tests: adapt test-check-pylint to run on Windows The line endings are explicitly converted because this was ending up with '\r (no-eol) (esc)' lines, in addition to the usual '\r (esc)' lines. I've seen the fakerc output on other recently installed systems though (10.13 and/or Fedora 26). Unfortunately, the output here uses '\\' on Windows, so glob away the whole path.

hghave: avoid a deadlock reading the child process's output The output of `pylint` is voluminous enough that it fills the buffer on Windows, and waited for the parent to read it out. But the parent was waiting on the child to exit. I'm not sure what the intent of setting `ret = -1` in the exception handler just above this was...

lfs: bypass wrapped functions when reposetup() hasn't been called (issue5902) There are only a handful of methods that access repo attributes that are applied in reposetup(). The `diff` test covers all of the commands that call scmutil.prefetchfiles(). Along the way, I saw that adding files and upgrading the repo format were also problems (also tested here). I don't think running `hg serve` through the commandserver is sane, but I conditionalized both the capabilities and the wsgirequest handler because it's trivially correct. It doesn't look like there has ever been a caller of candownload(), so there's no test for that path. The upload case isn't testable, because uploadblobs() bails if there are no pointers. The requirement should be added any time pointers are introduced, and that would force the extension to be loaded specifically for the repo. This covers `debuglfsupload`, the pre-push hook (which isn't set until the repo is promoted to LFS), and uploadblobsfromrevs(), which can be called by other extensions. I think readfromstore() and writetostore() are only reachable as a flag processor for revlog.REVIDX_EXTSTORED, and a requirement is added as soon as that is seen, so I don't think those are a problem.

revlog: disallow setting uncompressed length to None Backed out changeset a4942675de6b

unionrepo: fill in uncompressed length of revlog entry It can be either -1 or a valid length, but shouldn't be None. IIUC, we can simply trust the length retrieved from the revlog to be overlaid. I don't bother thinking whether the compressed length can be copied as well. We'll need to fix it later.

fuzz: extract some common utilities and use modern C++ idioms Alex Gaynor suggested we should probably copy the left and right sides of diffs to new blocks so we can detect over-reads in the diffing code, and I agree. Once I got into that, I realized we should do things with C++17 idioms rather than keep using malloc() and free(). This change is the result. I tried to split it more than this and failed. Everything still compiles and works in the oss-fuzz container, so I think we can count on C++17 being available! Differential Revision: https://phab.mercurial-scm.org/D3675

transaction-summary: show phase changes statistics in pull/unbundle Upon pull or unbundle, we display a message with the number of changesets which phase became public. Noticeably, this new message would appear even if no new changeset were added (below the "no changes found" message), thus indicating that something actually happened to the local repository.

outgoing: pay attention to `default:pushurl` for bookmarks and subrepos The problem here was that `default:pushurl` and `default` get translated to a single entry in `ui.paths` named 'default', with an attribute for 'pushloc', 'loc', and 'rawloc'. ui.expandpath() then always takes the `rawloc` attribute. Maybe the ui.expandpath() API is busted and should be removed? Or maybe getpath() should return a copy that adds an attribute reflecting the URL of the path chosen? I thought that I could remove the code in hg._outgoing() and pass the location resolved in commands.py as `dest`, but unfortunately that code is needed there to resolve #branch type URLs. Maybe that should be pulled up to commands.py, because I can't see any reasonable behavior for a subrepo path that's constructed out of that type of URL. The push command already resolves this early, so that works properly. But it looks like bundle, histedit, largefiles, patchbomb, and summary use a similar pattern, so they are likely similarly affected.

revlog: make chainbase cache its result for the correct revision Previously, as 'rev' was our iterator, we were always caching the chain base for the second revision of the chain, or for the base itself.

revlog: make getcandidaterevs more consistent about updating tested revs set Like in previous cases, update the set of tested revisions after yielding

templatekw: make getrenamed() return only filename, not nodeid No callers cared about the nodeid and I want to make getrenamed() not look up the node (although it's currently free, I hope to store copy info in changesets and not include the nodeid).

py3: wrap tempfile.NamedTemporaryFile() to return bytes fp.name Unlike its name, tempfile.NamedTemporaryFile is not a class, so I renamed the pycompat version to look like a plain function. Since temp.name uses in the infinitepush extension aren't bytes-safe, this patch leaves them unmodified. Another weird thing is tempfile.mktemp(), which does not accept bytes suffix nor prefix. Sigh.

py3: wrap tempfile.mkdtemp() to use bytes path This also flips the default to use a bytes path on Python 3.

py3: wrap tempfile.mkstemp() to use bytes path This patch just flips the default to use a bytes path on Python 3. ca1cf9b3cce7 is backed out as the bundlepath should be bytes now.

extensions: remove strip_init=True from _disabledpaths() It's no longer used.

extensions: peek command table of disabled extensions without importing With chg where demandimport disabled, and if disk cache not warm, it took more than 5 seconds to get "unknown command" error when you typo a command name. This is horrible UX. The new implementation is less accurate than the original one as Python can do anything at import time and cmdtable may be imported from another module, but I think it's good enough. Note that the new implementation has to parse .py files, which is slightly slower than executing .pyc if demandimport is enabled.

lfs: clarify pointer validation error messages It wasn't obvious that LFS was involved from the error messages when `hg verify` fails.

The '\' printed output on Windows is because each file is run through repo.pathto() -> dirstate.pathto() -> util.pathto(). (And that function states that the argument uses '/' separators.) I fixed a similar issue in 362096cfdb1f, and given the apparent need for these strings to be in '/' format, I wonder if cmdutil.dirnode() should be rewritten to avoid os.path.join(). But it looks like all entries added to the temporary terse dict should use '/' now, and cmdutil.tersedir() looks like the only user.

filemerge: don't pass function name as loadpath's module_name param

phases: define an official tuple of phases we do not share Same motivation as for `mutablephases`, having a single definition helps with updating phases logic.

phases: define an official tuple of mutable phases Such tuple was already manually defined in a couple of place. Having an official definition makes it easy to introduce of new phases.

repoview: use 'phasecache.getrevset' when computing 'unserved' filter This reuses a precomputed set, being much faster than manual iteration. Computing the "unserved" filter speed up by 55%. before: wall 0.014671 comb 0.020000 user 0.020000 sys 0.000000 (best of 180) after: wall 0.006623 comb 0.010000 user 0.010000 sys 0.000000 (best of 401) The "unserved" filter is used to restrict the revisions client can pull from a server. (eg: secret changesets)

graft: drop --user and --date values info from hint in case of conflicts After previous patch, we have started preserving user and date values in graftstate and reusing them during `hg graft --continue`. Now passing --user and --date again with --continue makes no sense. Let's drop them from the hint. Differential Revision: https://phab.mercurial-scm.org/D3660
