pycompat: explicitly prefix builtin attr usage with `builtins.`
It doesn't seem like this would fix any bug, because the wrapped functions that
take bytes instead of str are defined after these calls. But PyCharm was
flagging the second and third uses, saying "Type 'str' doesn't have expected
attribute 'decode'". It wasn't flagging the first, but I changed it for
consistency.
A new repository uses zlib storage, which doesn't need a requirement
$ cat << EOF >> $HGRCPATH
> [format]
> # stabilize test accross variant
> revlog-compression=zlib
> EOF
$ hg init default
$ cd default
$ hg debugrequires | grep compression
[1]
$ touch foo
$ hg -q commit -A -m 'initial commit with a lot of repeated repeated repeated text to trigger compression'
$ hg debugrevlog -c | grep 0x78
0x78 (x) : 1 (100.00%)
0x78 (x) : 110 (100.00%)
$ cd ..
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'
$ hg debugrequires | grep compression
[1]
$ hg debugrevlog -c | grep 0x78
0x78 (x) : 2 (100.00%)
0x78 (x) : 199 (100.00%)
$ cd ..
#if zstd
$ hg --config format.revlog-compression=zstd init zstd
$ cd zstd
$ hg debugrequires | grep compression

$ touch foo
$ hg -q commit -A -m 'initial commit with a lot of repeated repeated repeated text'
$ hg debugrevlog -c | grep 0x28
