are running.

A new repository uses zlib storage, which doesn't need a requirement
$ cat << EOF >> $HGRCPATH

> revlog-compression=zlib
> EOF

$ touch foo
$ hg -q commit -A -m 'initial commit with a lot of repeated repeated repeated text to trigger compression'

Unknown compression engine to format.compression aborts
$ hg --config format.revlog-compression=unknown init unknown
abort: compression engines "unknown" defined by format.revlog-compression not available
(run "hg debuginstall" to list available compression engines)
[255]
unknown compression engine in a list with known one works fine
$ hg --config format.revlog-compression=zlib,unknown init zlib-before-unknow
$ hg --config format.revlog-compression=unknown,zlib init unknown-before-zlib
A requirement specifying an unknown compression engine results in bail
$ hg init unknownrequirement
$ cd unknownrequirement
$ echo exp-compression-unknown >> .hg/requires
$ hg log
abort: repository requires features unknown to this Mercurial: exp-compression-unknown
(see https://mercurial-scm.org/wiki/MissingRequirement for more information)
[255]
$ cd ..
Specifying a new format.compression on an existing repo won't introduce data
with that engine or a requirement
$ cd default
$ touch bar
$ hg --config format.revlog-compression=none -q commit -A -m 'add bar with a lot of repeated repeated repeated text'
