revlog: simplify rawtext return value
We're always returning a tuple even though only the raw text is being used,
and we're rebuilding another tuple again higher.
As a bonus, this will remove one tuple creation and deletion
per `raw_text` call, hence fewer gc calls, etc.

setup
=====
$ hg init src
$ cd src
$ echo 1 > root
$ hg add root
$ hg ci -Am R_0
$ hg branch A
marked working directory as branch A
(branches are permanent and global, did you want a bookmark?)
$ echo 42 > bar
$ hg add bar
$ hg ci -Am A_0
$ echo 1337 > bar
$ hg ci -Am A_1
$ hg update 'desc(R_0)'
0 files updated, 0 files merged, 1 files removed, 0 files unresolved
$ echo 1 > foo
$ hg add foo
$ hg ci -Am B_0
$ hg log -G

Actual tests
============
Initial cloning if needed
-------------------------
$ hg admin::chainsaw-update --dest repo --rev default --source ./src
no such directory: "repo"
creating repository at "repo"
recovering after interrupted transaction, if any
no interrupted transaction available
pulling from ./src
updating to revision 'default'
2 files updated, 0 files merged, 0 files removed, 0 files unresolved
chainsaw-update to revision 'default' for repository at '$TESTTMP/repo' done
$ cd repo
$ hg log -G

Test lock breacking capabilities
--------------------------------
Demonstrate lock-breaking capabilities with locks that regular Mercurial
operation would not break, because the hostnames registered in locks differ
from the current hostname (happens a lot with succesive containers):
$ ln -s invalid.host.test/effffffc:171814 .hg/store/lock
$ ln -s invalid.host.test/effffffc:171814 .hg/wlock
$ hg debuglock
lock: (.*?), process 171814, host invalid.host.test/effffffc \((\d+)s\) (re)
wlock: (.*?), process 171814, host invalid.host.test/effffffc \((\d+)s\) (re)
[2]
$ hg admin::chainsaw-update --no-purge-ignored --dest . --rev default --source ../src
loaded repository at "."
had to break store lock
had to break working copy lock
recovering after interrupted transaction, if any
no interrupted transaction available
pulling from ../src
updating to revision 'default'
0 files updated, 0 files merged, 0 files removed, 0 files unresolved
chainsaw-update to revision 'default' for repository at '$TESTTMP/repo' done
Test file purging capabilities
------------------------------
Let's also add local modifications (tracked and untracked) to demonstrate the
purging.
$ echo untracked > bar
$ echo modified > foo
$ hg status -A
M foo
? bar
C root
$ echo 2 > ../src/foo
$ hg -R ../src commit -mB_1
$ hg admin::chainsaw-update --dest . --rev default --source ../src -q
no interrupted transaction available
$ hg log -G

Now behaviour with respect to ignored files: they are not purged if
the --no-purge-ignored flag is passed, but they are purged by default
$ echo bar > .hgignore
$ hg ci -Aqm hgignore
$ echo ignored > bar
$ hg status --all
I bar
C .hgignore
C foo
C root
$ hg admin::chainsaw-update --no-purge-ignored --dest . --rev default --source ../src -q
no interrupted transaction available
$ hg status --all
I bar
C .hgignore
C foo
C root
$ cat bar
ignored
$ hg admin::chainsaw-update --dest . --rev default --source ../src -q
no interrupted transaction available
$ hg status --all
C .hgignore
C foo
C root
$ test -f bar

test --minimal-initial-cloning variant
--------------------------------------
With `--minimal-initial-cloning`, there is no "requesting all changes"
message. Hence clone bundles would be bypassed (TODO test both cases
# with an actual clone-bundle)
$ cd ..
$ hg admin::chainsaw-update --dest repo2 --rev default --source src --initial-clone-minimal
no such directory: "repo2"
creating repository at "repo2"
recovering after interrupted transaction, if any
no interrupted transaction available
pulling from src
updating to revision 'default'
2 files updated, 0 files merged, 0 files removed, 0 files unresolved
chainsaw-update to revision 'default' for repository at '$TESTTMP/repo2' done
$ cd repo2
$ hg log -G
