$ cacheexists() {

# XXX need to test that the tag cache works when we strip an old head
# and add a new one rooted off non-tip: i.e. node and rev of tip are the
# same, but stuff has changed behind tip.
Setup:
$ hg init t
$ cd t
$ cacheexists
no tag cache
$ hg id
000000000000 tip
$ cacheexists
no tag cache
$ echo a > a
$ hg add a
$ hg commit -m "test"
$ hg co
0 files updated, 0 files merged, 0 files removed, 0 files unresolved
$ hg identify
acb14030fe0a tip
$ cacheexists
tag cache exists
Try corrupting the cache
$ printf 'a b' > .hg/cache/tags
$ hg identify
.hg/cache/tags is corrupt, rebuilding it
acb14030fe0a tip
$ cacheexists
tag cache exists
$ hg identify
acb14030fe0a tip
Create local tag with long name:
$ T=`hg identify --debug --id`
$ hg tag -l "This is a local tag with a really long name!"
$ hg tags
tip 0:acb14030fe0a
This is a local tag with a really long name! 0:acb14030fe0a
$ rm .hg/localtags
Create a tag behind hg's back:
$ echo "$T first" > .hgtags
$ cat .hgtags
acb14030fe0a21b60322c440ad2d20cf7685a376 first
$ hg add .hgtags
$ hg commit -m "add tags"
$ hg tags
tip 1:b9154636be93
first 0:acb14030fe0a
$ hg identify
b9154636be93 tip
Repeat with cold tag cache:
$ rm -f .hg/cache/tags
$ hg identify
b9154636be93 tip
And again, but now unable to write tag cache:
$ rm -f .hg/cache/tags
$ chmod 555 .hg
$ hg identify
b9154636be93 tip
$ chmod 755 .hg
Create a branch:
$ echo bb > a
$ hg status
M a
$ hg identify
b9154636be93+ tip
$ hg co first
0 files updated, 0 files merged, 1 files removed, 0 files unresolved
$ hg id
acb14030fe0a+ first
$ hg -v id
acb14030fe0a+ first
$ hg status
M a
$ echo 1 > b
$ hg add b
$ hg commit -m "branch"
created new head
$ hg id
c8edf04160c7 tip
Merge the two heads:
$ hg merge 1
1 files updated, 0 files merged, 0 files removed, 0 files unresolved
(branch merge, don't forget to commit)
$ hg id
c8edf04160c7+b9154636be93+ tip
$ hg status
M .hgtags
$ hg commit -m "merge"
Create a fake head, make sure tag not visible afterwards:
$ cp .hgtags tags
$ hg tag last
$ hg rm .hgtags
$ hg commit -m "remove"
$ mv tags .hgtags
$ hg add .hgtags
$ hg commit -m "readd"
$
$ hg tags
tip 6:35ff301afafe
first 0:acb14030fe0a
Add invalid tags:
$ echo "spam" >> .hgtags
$ echo >> .hgtags
$ echo "foo bar" >> .hgtags
$ echo "a5a5 invalid" >> .hg/localtags
$ echo "committing .hgtags:"
committing .hgtags:
$ cat .hgtags
acb14030fe0a21b60322c440ad2d20cf7685a376 first
spam
foo bar
$ hg commit -m "tags"
Report tag parse error on other head:
$ hg up 3
1 files updated, 0 files merged, 0 files removed, 0 files unresolved
$ echo 'x y' >> .hgtags
$ hg commit -m "head"
created new head
$ hg tags
.hgtags@75d9f02dfe28, line 2: cannot parse entry
.hgtags@75d9f02dfe28, line 4: node 'foo' is not well formed
