packaging: add dependencies to the PyOxidizer build on macOS Otherwise, we get a bunch of test failures for missing things like pygments, or tests skipped entirely. The input file is a copy/paste from the equivalent Windows file, but with dulwich, pygit2, and pytest-vcr commented out because the build process errors out with them, flagging them as incompatible with loading from memory. I have no idea if that's actually true or not, because I've noticed that if I don't `make clean` after every build, the next build flags the watchman stuff as incompatible with loading from memory. The remaining failures are: Failed test-alias.t: output changed Failed test-basic.t: output changed Failed test-check-help.t: output changed Failed test-commit-interactive.t: output changed Failed test-extension.t: output changed Failed test-help.t: output changed Failed test-i18n.t: output changed Failed test-log.t: output changed Failed test-qrecord.t: output changed Failed test-share-safe.t: output changed Most of the issues seem related to loading help for disabled extensions from `hgext.__index__`, namely the full extension help being unavailable, not being able to resolve what commands are provided by what extension, and not having the command level help available. test-log.t, test-commit-interactive.t, and test-i18n.t look like i18n (or lack thereof) issues. test-basic.t is just odd: @@ -55,7 +55,7 @@ On Python 3, stdio may be None: $ hg debuguiprompt --config ui.interactive=true 0<&- - abort: Bad file descriptor (no-rhg !) + abort: response expected abort: response expected (rhg !)

revlog.parseindex must be able to parse the index file even if
an index entry is split between two 64k blocks.  The ideal test
would be to create an index file with inline data where
64k < size < 64k + 64 (64k is the size of the read buffer, 64 is
the size of an index entry) and with an index entry starting right
before the 64k block boundary, and try to read it.
We approximate that by reducing the read buffer to 1 byte.
