run-tests: introduce a --pyoxidized option
This options make it possible to use the pyoxidizer version to run the tests.
This is a first basic version that is windows only.
The test needs a working python, with Mercurial installed. However the
pyoxidizer product is "self contains" without a "usable" Python. There have been
discussion to have a fully functional `hg admin::python` command providing a
fully functional python interpreter, but nothing is of the sort is ready yet. In
In the meantime we use an hybrid approach, similar to what we do for testing
`rhg`. We install a full "normal" Mercurial, but also the pyxodizer product as
the official `hg binary`. That way, we use the pyoxidizer version or everything,
but test that needs to run python have it available, with a fully functional
Mercurial package.
This first version is pretty basic (Windows only, no --local, not
--with-pyoxidized), but it runs, various bug that we will have to fix.

Test correctness of revlog inline -> non-inline transition ---------------------------------------------------------- Helper extension to intercept renames. $ cat > $TESTTMP/intercept_rename.py << EOF > import os > import sys > from mercurial import extensions, util > > def extsetup(ui): > def close(orig, *args, **kwargs): > path = util.normpath(args[0]._atomictempfile__name) > if path.endswith(b'/.hg/store/data/file.i'): > os._exit(80) > return orig(*args, **kwargs) > extensions.wrapfunction(util.atomictempfile, 'close', close) > EOF Test offset computation to correctly factor in the index entries themselve. Also test that the new data size has the correct size if the transaction is aborted after the index has been replaced. Test repo has one small, one moderate and one big change. The clone has the small and moderate change and will transition to non-inline storage when adding the big change. $ hg init troffset-computation --config format.revlog-compression=none $ cd troffset-computation $ printf '%20d' '1' > file $ hg commit -Aqm_ $ printf '%1024d' '1' > file $ hg commit -Aqm_ $ dd if=/dev/zero of=file bs=1k count=128 > /dev/null 2>&1 $ hg commit -Aqm_ $ cd .. $ hg clone -r 1 troffset-computation troffset-computation-copy --config format.revlog-compression=none -q $ cd troffset-computation-copy Reference size: $ f -s .hg/store/data/file* .hg/store/data/file.i: size=1174 $ cat > .hg/hgrc <<EOF > [hooks] > pretxnchangegroup = python:$TESTDIR/helper-killhook.py:killme > EOF #if chg $ hg pull ../troffset-computation pulling from ../troffset-computation [255] #else $ hg pull ../troffset-computation pulling from ../troffset-computation [80] #endif $ cat .hg/store/journal | tr -s '\000' ' ' | grep data/file | tail -1 data/file.i 128 The first file.i entry should match the size above.

Now retry the procedure but intercept the rename of the index and check that the journal does not contain the new index size. This demonstrates the edge case where the data file is left as garbage. $ hg clone -r 1 troffset-computation troffset-computation-copy2 --config format.revlog-compression=none -q $ cd troffset-computation-copy2 $ cat > .hg/hgrc <<EOF > [extensions] > intercept_rename = $TESTTMP/intercept_rename.py > [hooks] > pretxnchangegroup = python:$TESTDIR/helper-killhook.py:killme > EOF #if chg $ hg pull ../troffset-computation pulling from ../troffset-computation [255] #else $ hg pull ../troffset-computation pulling from ../troffset-computation [80] #endif $ cat .hg/store/journal | tr -s '\000' ' ' | grep data/file data/file.i 1174 data/file.d 0 data/file.d 1046 $ hg recover rolling back interrupted transaction (verify step skipped, run `hg verify` to check your repository content) $ f -s .hg/store/data/file* .hg/store/data/file.d: size=1046 .hg/store/data/file.i: size=1174 $ hg tip changeset: 1:3ce491143aec tag: tip user: test date: Thu Jan 01 00:00:00 1970 +0000 summary: _ $ hg verify checking changesets checking manifests crosschecking files in changesets and manifests checking files checked 2 changesets with 2 changes to 1 files $ cd ..
