Summary: Now that all our repos are treemanifest, let's enable the extension by default in tests. Once we're certain no one needs it in production we'll also make it the default in core Mercurial. This diff includes a minor fix in treemanifest to be aware of always-enabled extensions. It won't matter until we actually add treemanifest to the list of default enabled extensions, but I caught this while testing things.

Setup

|
|
$ enable obsstore

Check diagnosis, debugging information

1) Setup configuration
|

$ mkcommit() {
|
|
> echo "$1" > "$1"
|
|
> hg add "$1"
|
|
> echo "add $1" > msg
|
|
> echo "" >> msg
|
|
> hg ci -l msg
|
|
> }
|
|
|
|
2) Basic cache testing
|
|
|
|
$ mkdir cachetesting
|
|
$ cd cachetesting
|
|
$ hg init
|
|
$ cat >> .hg/hgrc << EOF
|
|
> [extensions]

|
|
> [fastmanifest]
|
|
> cachecutoffdays=-1
|
|

Test usecache=False prevents cache creation

Here we expect a cache hit of 100% because we are based of revision -1 that
|
|
is cached

Trim the cache to at most 1kb, we should start from the oldest entry to the
