Durham Goode 98d9269874 server: copy hg to a new hg-server directory
Summary:
Create a fork of the Mercurial code that we can use to build server
rpms. The hg servers will continue to exist for a few more months while we move
the darkstorm and ediscovery use cases off them. In the mean time, we want to
start making breaking changes to the client, so let's create a stable copy of
the hg code to produce rpms for the hg servers.

The fork is based off c7770c78d, the latest hg release.

This copies the files as is, then adds some minor tweaks to get it to build:
- Disables some lint checks that appear to be bypassed by path
- sed replace eden/scm with eden/hg-server
- Removed a dependency on scm/telemetry from the edenfs-client tests since
  scm/telemetry pulls in the original eden/scm/lib/configparser which conflicts
  with the hg-server conflict parser.

Issue3841: check annotation of the file of which filelog includes
merging between the revision and its ancestor
to reproduce the situation with recent Mercurial, this script uses (1)
"hg debugsetparents" to merge without ancestor check by "hg merge",
and (2) the extension to allow filelog merging between the revision
and its ancestor by overriding "repo._filecommit".

Test empty annotate output
$ printf '\0' > binary
$ touch empty
$ hg ci -qAm 'add binary and empty files'
$ hg annotate binary empty
binary: binary file
$ hg annotate -Tjson binary empty
[
{
"abspath": "binary",
"path": "binary"
},
{
"abspath": "empty",
"lines": [],
"path": "empty"

]
Test annotate with whitespace options
$ cd ..
$ hg init repo-ws
$ cd repo-ws
$ cat > a <<EOF
> aa
>
> b b
> EOF
$ hg ci -Am "adda"
adding a
$ sed 's/EOL$//g' > a <<EOF
> a a
>
> EOL
> b b
> EOF
$ hg ci -m "changea"
Annotate with no option
$ hg annotate a
1: a a
0:
1:
1: b b
Annotate with --ignore-space-change
$ hg annotate --ignore-space-change a
1: a a
1:
0:
0: b b
Annotate with --ignore-all-space
$ hg annotate --ignore-all-space a
0: a a
0:
1:
0: b b
Annotate with --ignore-blank-lines (similar to no options case)
$ hg annotate --ignore-blank-lines a
1: a a
0:
1:
1: b b
$ cd ..
Annotate with linkrev pointing to another branch
------------------------------------------------
create history with a filerev whose linkrev points to another branch
$ hg init branchedlinkrev
$ cd branchedlinkrev
$ echo A > a
$ hg commit -Am 'contentA'
adding a
$ echo B >> a
$ hg commit -m 'contentB'
$ hg up --rev 'desc(contentA)'
1 files updated, 0 files merged, 0 files removed, 0 files unresolved
$ echo unrelated > unrelated
$ hg commit -Am 'unrelated'
adding unrelated
$ hg graft -r 'desc(contentB)'
grafting fd27c222e3e6 "contentB"
$ echo C >> a
$ hg commit -m 'contentC'
$ echo W >> a
$ hg log -G

Annotate should list ancestor of starting revision only
$ hg annotate a
0: A
3: B
4: C
$ hg annotate a -r 'wdir()'
0 : A
3 : B
4 : C
4+: W
Even when the starting revision is the linkrev-shadowed one:
$ hg annotate a -r 'max(desc(contentB))'
0: A
3: B
$ cd ..
