Summary:
D13853115 adds `edenscm/` to `sys.path` and code still uses `import mercurial`.
That has nasty problems if both `import mercurial` and
`import edenscm.mercurial` are used, because Python would think `mercurial.foo`
and `edenscm.mercurial.foo` are different modules so code like
`try: ... except mercurial.error.Foo: ...`, or `isinstance(x, mercurial.foo.Bar)`
would fail to handle the `edenscm.mercurial` version. There are also some
module-level states (ex. `extensions._extensions`) that would cause trouble if
they have multiple versions in a single process.
Change imports to use the `edenscm` so ideally the `mercurial` is no longer
imported at all. Add checks in extensions.py to catch unexpected extensions
importing modules from the old (wrong) locations when running tests.

Summary:
Update bookmarks to work correctly when shared. Rather than copying the
bookmarks file over after transaction handling, update the file in both
locations when bookmarks are shared.

Summary:
Previously `hg server` uses `HGPORT` that might be in use. This patch uses
`-p 0 --port-file ...` so `hg server` always gets assigned a free port.
The change was first made by the following Ruby script:
```
re = /^ \$ hg serve(.*) -p \$(HGPORT[12]?) (.*[^\\])$\n \$/
Dir['*.t'].each do |path|
old = File.read(path)
new = old.lines.map do |l|
next l if l[/\(glob\)/] or not l['$HGPORT'] or l[/^ [$>]/]
"#{l.chomp} (glob)\n"
end.join.gsub re, <<-'EOS'.chomp
$ hg serve\1 -p 0 --port-file $TESTTMP/.port \3
$ \2=`cat $TESTTMP/.port`
$
EOS
File.write(path, new) if old != new
end
```
Then there are some manual changes:
run-tests.py: It now treats `$HGPORT` in output as glob pattern `*`, since
it does not know the assigned value in tests.
test-bookmarks-pushpull.t, test-https.t: Some `hg pull`s were changed to use
explicit paths instead of relying on `.hgrc` since the test restarts the
server and `.hg/hgrc` having an outdated URL.
test-schemes.t: The test writes `$HGPORT` to `.hgrc` before assigning it.
Changed the order so the correct `$HGPORT` is written.
test-patchbomb-tls.t: Changed `(?) (glob)` to `(glob) (?)`.

Summary:
`lfs` is the better large file solution. `largefiles` is rarely used, and
its implementation is less clean. So let's remove it.
Test Plan:
Ran all tests. A subrepo test was removed instead of cleaned up since the
longer term plan is to also drop subrepo support.

Share extension now also share caches reads and writes. Not sharing caches
results in costly caches recomputations which can takes up to minutes when
using shares on large repositories.
There are a couple of file in the '.hg/cache/' that depends of the current
visibility. Visibility can be affected by the working copy location, something
which is specific to each share. We ignores them for this series because they:
* are the minority,
* already have a good fallback to other precomputed caches,
* are only affected when people use the experimental evolution feature.
Storing a relative path the source repository is useful when exporting
repositories over the network or when they're located on external
drives where the mountpoint isn't always fixed.
Currently, Mercurial interprets paths in `.hg/shared` relative to
$PWD. I suspect this is very much unintentional, and you have to
manually edit `.hg/shared` in order to trigger this behaviour.
However, on the off chance that someone might rely on it, I added a
new capability called 'relshared'. In addition, this makes earlier
versions of Mercurial fail with a graceful error.
I should note that I haven't tested this patch on Windows.
Before this patch, checking HG_PENDING in bookmarks.py might cause
unintentional reading unrelated '.hg/bookmarks.pending' in, because it
just examines existence of HG_PENDING environment variable.
This patch uses txnutil.trypending() to check HG_PENDING strictly.
This patch also changes share extension.
Enabling share extension (+ bookmark sharing) makes
bookmarks._getbkfile() receive repo to be shared (= "srcrepo"). On the
other hand, HG_PENDING always refers current working repo (=
"currepo"), and bookmarks.pending is written only into currepo.
Therefore, we should try to read .hg/bookmarks.pending of currepo in
at first. If it doesn't exist, we try to read .hg/bookmarks of srcrepo
in.
Even after this patch, an external hook spawned in currepo can't see
pending changes in currepo via srcrepo, even though such changes
become visible after closing transaction, because there is no easy and
cheap way to know existence of pending changes in currepo via srcrepo.
Please see https://www.mercurial-scm.org/wiki/SharedRepository, too.
BTW, this patch may cause failure of bisect in the repository of
Mercurial itself, if examination at bisecting assumes that an external
hook can see all pending changes while nested transactions across
repositories.
This invisibility issue will be fixed by subsequent patch, which
allows HG_PENDING to refer multiple repositories.
$TESTDIR is added to the path, so this is superfluous. Also,
inconsistent use of quotes means we might have broken on tests with
paths containing spaces.
This patch adds the -B/--bookmarks option to the share command added by the
share extension. All it does for now is create a marker, 'bookmarks.shared',
that will be used by future code to implement the sharing functionality.
This does not cause any behavioral change unless a 'bookmarks.shared' marker
file exists. A future change will add UI to create this file when a repository
is shared.
get-with-headers.py took the http GET parameter as a command line parameter
that had to start with '/'. MSYS on windows will mangle such paths.
Instead of applying a workaround everywhere (such as an extra '/') we let
get-with-headers.py add the mandatory '/'. That is consistent with the
url path handling in the Mercurial url class.
A few tests sent 'GET ?cmd=...' which is invalid. They will now send 'GET
/?cmd=...'.
This will not enable any tests for being run on windows - only remove one
reason they were disabled.
Many tests didn't change back from subdirectories at the end of the tests ...
and they don't have to. The missing 'cd ..' could always be added when another
test case is added to the test file.
This change do that tests (99.5%) consistently end up in $TESTDIR where they
started, thus making it simpler to extend them or move them around.
Globbing is usually used for filenames, so on windows it is reasonable and very
convenient that glob patterns accepts '\' or '/' when the pattern specifies
'/'.
This is extremely handy for those occasional circumstances where you
need to edit .hg/sharedpath manually, since modern Unix text editors
make it surprisingly difficult to create a text file with no trailing
newline.
