Test the "tracked hint" feature
===============================
The tracked hint feature provide a file that get updated when the set of tracked
files get updated.
basic setup

$ hg init tracked-hint-test
$ cd tracked-hint-test
$ hg debugbuilddag '.+10' -n

key-file exists
-----------
The tracked hint file should exist
$ ls -1 .hg/dirstate*
.hg/dirstate
.hg/dirstate-tracked-hint
key-file stay the same if the tracked set is unchanged
------------------------------------------------------
(copy its content for later comparison)
$ cp .hg/dirstate-tracked-hint ../key-bck
$ echo foo >> nf0
$ sleep 1
$ hg status
M nf0
$ diff --brief .hg/dirstate-tracked-hint ../key-bck
$ hg revert -C nf0
$ sleep 1
$ hg status
$ diff --brief .hg/dirstate-tracked-hint ../key-bck
key-file change if the tracked set is changed manually
------------------------------------------------------
adding a file to tracking
$ cp .hg/dirstate-tracked-hint ../key-bck
$ echo x > x
$ hg add x
$ diff --brief .hg/dirstate-tracked-hint ../key-bck
Files .hg/dirstate-tracked-hint and ../key-bck differ
[1]
remove a file from tracking
(forget)
$ cp .hg/dirstate-tracked-hint ../key-bck
$ hg forget x
$ diff --brief .hg/dirstate-tracked-hint ../key-bck
Files .hg/dirstate-tracked-hint and ../key-bck differ
[1]
(remove)
$ cp .hg/dirstate-tracked-hint ../key-bck
$ hg remove nf1
$ diff --brief .hg/dirstate-tracked-hint ../key-bck
Files .hg/dirstate-tracked-hint and ../key-bck differ
[1]
key-file changes on revert (when applicable)
--------------------------------------------
$ cp .hg/dirstate-tracked-hint ../key-bck
$ hg status
R nf1
? x
$ hg revert --all
undeleting nf1
$ hg status
? x
$ diff --brief .hg/dirstate-tracked-hint ../key-bck

`hg update` does affect the key-file (when needed)
--------------------------------------------------
update changing the tracked set
(removing)
$ cp .hg/dirstate-tracked-hint ../key-bck
$ hg status --rev . --rev '.#generations[-1]'
R nf10
$ hg up '.#generations[-1]'
0 files updated, 0 files merged, 1 files removed, 0 files unresolved
$ diff --brief .hg/dirstate-tracked-hint ../key-bck
Files .hg/dirstate-tracked-hint and ../key-bck differ

$ cp .hg/dirstate-tracked-hint ../key-bck
$ hg status --rev . --rev '.#generations[1]'
A nf10
$ hg up '.#generations[1]'

$ diff --brief .hg/dirstate-tracked-hint ../key-bck

update not affecting the tracked set
$ echo foo >> nf0
$ hg commit -m foo
$ cp .hg/dirstate-tracked-hint ../key-bck
$ hg status --rev . --rev '.#generations[-1]'
M nf0
$ hg up '.#generations[-1]'

$ diff --brief .hg/dirstate-tracked-hint ../key-bck
Test upgrade and downgrade
==========================
$ ls .hg/dirstate-tracked-hint
.hg/dirstate-tracked-hint
$ hg debugrequires | grep 'tracked'
dirstate-tracked-key-v1
downgrade
$ hg debugupgraderepo --config format.use-dirstate-tracked-hint=no --run --quiet
upgrade will perform the following actions:
requirements
preserved: * (glob)
removed: dirstate-tracked-key-v1
no revlogs to process
$ ls -1 .hg/dirstate-tracked-hint
ls: *.hg/dirstate-tracked-hint*: $ENOENT$ (glob)
[2]
$ hg debugrequires | grep 'tracked'
[1]
upgrade
$ hg debugupgraderepo --config format.use-dirstate-tracked-hint=yes --run --quiet
upgrade will perform the following actions:
requirements
preserved: * (glob)
added: dirstate-tracked-key-v1
no revlogs to process
$ ls -1 .hg/dirstate-tracked-hint
.hg/dirstate-tracked-hint
$ hg debugrequires | grep 'tracked'
