Mtime-based caching: stat the directory tree once per prompt (~2ms)
and skip full activation when nothing has changed.
- Compare PYENV_VERSION, VIRTUAL_ENV, PWD; shortcut when PYENV_VERSION matches
- Walk PWD to / for .python-version (stop at first; include broken symlinks)
- Path list built once on miss, stored as array (spaces in paths)
- Global version file skipped when local version active
- version-name hooks checked at init; if present, caching disabled
- Covers bash, zsh, and fish
* Adjust tests: update Pip URLs, update expected output to match newer code
* Test library: improve failure message to eliminate the illusion of extra leading space in "actual" output
* Use Bats 1.2.0 like Pyenv
* Install greadlink for old MacOS
* Delete duplicate test
Use `set -gx` instead of `setenv` for fish shell.
Fix test "activate if the first virtualenv is a virtualenv": it was asserting
the output was of bash form, but not specifying that in the test — it now does.
Fixes https://github.com/pyenv/pyenv-virtualenv/issues/216.
This fixes displaying the note, in case "init" has been run manually
and/or the init is not in the expected place.
It removes the unnecessary calls to "grep".
pyenv-virtualenv-init will look at `$PYENV_SHELL` now, too.
Tests have been adjusted/fixed.
When the current pyenv environment is not a virtualenv, this line
exits with a return code of 1. This is annoying for those of us
who report the last return code in our own PROMPT_COMMAND, so
ignore the output of `pyenv activate` if we're not currently using
a virtualenv.
The situation is when in a directory containing python binary,
`pyenv prefix' will return empty (caused by `pyenv which' returning
"./python"). This change adds quotes for `test', otherwise `test' will
warn about missing argument.
