Summary:
Once all clients are in treeonly mode, we can make the server tree only
mode as well and stop producing flat manifests entirely. This will speed up
pushes, save space, etc. This patch adds support for that mode.

Summary:
Once we move to a treeonly world, there won't be any more manifest revlogs.
During the transition we'll still use hybrid manifest's though (the class, and
it will just resolve to treemanifests every time), so we need to support hybrid
manifests that don't actually have a revlog.
This also sets manifestlog._opener. We were already storing that on the other
manifestlog implementations, so we should do it on the main one for consistency
(and because this diff depends on it).

Summary:
It makes sure that adding new options to the commands won't break them. For
example, rage sparse output was broken, and this diff fixes it.
Note that this changes behavior of the rage - if, say, smartlog extension is not enabled on the client, then there will be no output in the rage. Previously it wasn't the case. I think that's not the big problem, because:
a) The extensions are the most common ones and enabled everywhere
b) If they are disabled, then we'll immediately see a problem in hg rage.
However I need to change a test to make it pass. I need to add extensions and change grep output, because `hg rage --preview` has a few lines with `blackbox` in it.

Summary:
Rewriting a set of commits where there are replacement relationship among the
commits do not have an optimal UX today. For example, `rebase -s A -d Z` or
`metaedit A` in the below graph. B1, B2, C will all be replaced. But the new B1
and B2 replacement won't have the B1 -> B2 relationship, and the "new B1"
appears to be revived.
```
o C
|
x B1 (amended as B2)
|
| o B2
|/
o A o Z
```
One solution is to avoid rebasing `obsolete()::`, as implemented in D7067121
for metaedit. That would result in
```
o C
|
x B1 (amended as B2) o new B2
| |
x A o new A
```
The stack of A, B1, C is forced to break into two parts. This is fine for
power users. But n00b users would wonder why C is left behind. Per discussion
with simpkins at an internal post about the metaedit case, we think a more
linear history is more user-friendly. That is:
```
o new C
|
x new B1 (amended as *new* B2)
|
| o new B2
|/
o new A
```
The stack stays in a same shape.
This diff implements the "copying obsmarkers" behavior at the "createmarkers"
level so everything using that API would get the feature for free, including
metaedit and rebase.
D7067121 is reverted since the new UX is preferred. The test added is for
`metaedit` command, changes to rebase will be added in a later patch.

Summary:
Recently we unified the client and server code paths a bit, which
can cause the treemanifest server to attempt to do a prefetch (which doesn't
make sense since it has no where to prefetch from). It ends up throwing an Abort
error about not having a remote server configured. The fix is to make the
prefetch path smarter about when it's run on the server and to throw a standard
MissingNodesError instead. That kind of error is already handled in the hybrid
repository case and we just eat it and server the flat manifests like normal.
Once we move to treeonly mode, that error handler will re-raise the exception so
real issues with missing nodes won't be hidden.

- p4 fast importer records the wrong parent of a file
This diff tries to fix these two issues.
In mercurial, if a file is added, deleted, and then added back, it should start a new file history when the file is added again.
For example,
commits commit1 commit2 commit3
actions add a.txt delete a.txt add a.txt
timeline ------------X------------X------------------------X------------
`hg debugindex a.txt` at commit3 shows a.txt as a new file without previous history
rev offset length delta linkrev nodeid p1 p2
0 0 3 -1 0 b789fdd96dc2 000000000000 000000000000
However, this is different in p4. `p4 filelog test.txt` gives you
//depot/Software/Apps/Main/Native/.castle/test.txt
... #3 change 523261 add on 2018/01/23 by zhihuih@devbig415 (text) 'test:add-again-same-file'
... #2 change 523254 delete on 2018/01/23 by zhihuih@devbig415 (text) 'testfile:delete'
... #1 change 523253 add on 2018/01/23 by zhihuih@devbig415 (text) 'testfile:add'
Currently, p4 fast importer preserves history the same way as p4, and this causes slowness (even timeout) in hg when it runs `hg log --traceback --template '{file_copies}' -r XXXX` on a revision that contains files with long history in p4 (mostly contributed by automation). To mitigate this, we want the p4 fast importer to behave the same way as hg, and starts a new history for a file that's added again.
Currently, p4 fast importer takes the tip of a filelog and treats that as the parent of the newly written entry diffusion/FBS/browse/master/fbcode/scm/hg/hgext/p4fastimport/importer.py;19ad9b05f50e3ff0265cdc7b4b45174dcf820343$468-469. This can be wrong when there are revisions from branches.
For example, if I edit file a in master in CL1, 2, 4, and I branch at CL3, and edit the file in branch in CL5, the current importer implementation will take filenode at CL4 as the parent of CL3
(CL1,2,3,4,5 corresponds to rev0,1,3,2,4)
{F120393661}
However, the correct behavior is to take filenode at CL2 as the parent of CL3
(CL1,2,3,4,5 corresponds to rev0,1,3,2,4)
{F120393662}
(This is also the example I use in `test-fb-hgext-p4fastimport-import-branch-filelogorder.t`, so if the description here looks confusing, please refer to the test)

Summary:

localpeer, and add the 'gettreepack' capability to localpeer if the repository
supports acting as a treemanifest server.
Also update the _addmanifestgroup() wrapper to only forbid it from being called
in a treemanifest server repository. When pulling from a local treemanifest
server repository this function may need to be invoked in the client
repository.

Summary:
The treemanifest extension now uses a pattern of
treemod._cansendtrees() to detect if it should send trees. pushrebase and
infinitepush were using a different pattern where they were sending trees if
they existed (in infinitepush's case it was ignoring the sendtrees config
entirely). Let's make these consistent.
The new behavior requires that trees exist for the commits we're trying to send.
In order for this to work, we'll need the logic that automatically converts a
flat manifest into a treemanifest so that we're never missing a tree we want to
send.

Summary:
When hg addremove needs to remove a file, remotefilelog tries to create a filenode in order to prefetch the removed files from the server. If the file is not in the parent context manifest, this throws an exception.
To solve this we have to first check if the file exists or not in the parent manifest. If the file does not exist in the manifest then we don't need to prefetch it, and addremove will behave like forget rather than remove.

'assignment', 'atomtrailers'}

content = open(path).read()
try:

except Exception:
print(' warning: failed to parse')
continue
hasxrange = red.find('atomtrailersnode', value=isxrange)
hasxrangefix = 'xrange = range' in content
if hasxrangefix or not hasxrange:
print(' no need to change')
continue
# find a place to insert the compatibility statement
changed = False
for node in red:
if node.type in headertypes:
continue
# node.insert_before is an easier API, but it has bugs changing
# other "finally" and "except" positions. So do the insert
# manually.
# # node.insert_before(xrangefix)
line = node.absolute_bounding_box.top_left.line - 1
lines = content.splitlines(1)
content = ''.join(lines[:line]) + xrangefix + ''.join(lines[line:])
changed = True
break
if changed:
# "content" is faster than "red.dumps()"
open(path, 'w').write(content)
print(' updated')
if __name__ == "__main__":
sys.exit(main(sys.argv[1:]))
