What is the preferred way to have 
./pants repl
open either a python2 or a python3 repl? Our old way of doing it (v1.18) does not seem to work anymore (we used 
. --pants-config-files="${BUILDROOT}/pants.py3.ini"
where 
pants.py3.ini
defined 
interpreter_constraints: ["CPython>=3.6.8,<4"]
).
h
Hello! Huh, that should still be working. What does `./pants --pants-config-files="${BUILDROOT}/pants.py3.ini" options | grep 
interpreter_constraints
return? Are you using the v1 repl implementation?
j
yes v1
interpreter_constraints: ["CPython>=3.6.8,<4"]
is what is in 
pants.py3.ini
interpreter_constraints: ["CPython>=2.7.15,<3","CPython>=3.6.8,<4"]
is what is in 
pants.ini
pants.py3.ini
in its entirety:
Copy code
[python-setup]
interpreter_constraints: ["CPython>=3.6.8,<4"]
I am using 1.25.0. 😊
If I clear my cache then it works.

but then it never leaves the the python version until I nuke the cache.
weird
h
but then it never leaves the the python version until I nuke the cache.
What do you mean? It sounds like the cache invalidation broke somewhere 😕 (Which is the entire prime motivation for v2, caching was really hard to get right in v1 and was entirely manual)
Is this the 
.pants.d
cache?
j
yes. I'm deleting 
~/.pants.d
and 
~/.cache/pants
between runs.
h
Try only deleting .pants.d. The global cache shouldn’t impact this afaict
j
ok
h
Alternatively, you can use the option —cache-ignore
👍🏽 1
This isn’t ideal - right now I’m trying to diagnose where the issue is.
j
let me see if I can isolate what is happening... I will be able to focus on this in about 30 min.

I think that’s iOS hehe. So frustrating
j
the real fault is all the years of StackExchangeOps (copy-paste). 😊

my other thing (🐉 🎲 ) ended early so I am working on it
Ignoring cache doesn't seem to be working as I'm getting 
[ivy]01:39:50 [WARN] /Users/raul/.cache/pants/setup/bootstrap-Darwin-x86_64/1.25.0_py36/lib/python3.6/site-packages/pants/engine/round_engine.py:45: DeprecationWarning: DEPRECATED: Ivy Resolve will be removed in version 1.27.0.dev0.
oh wait. that's not 
.pants.d
h
Yeah. You can ignore that deprecation warning with 
ignore_pants_warnings
tho! https://www.pantsbuild.org/docs/upgrade-tips#ignore-deprecation-messages-with-ignore_pants_warnings
j
I need to get my test sequence in order.
--cache-ignore
does not seem to be ignoring 
~/.pants.d
.
Ok. It defiantly involves 
~/.pants.d
h
To clarify, do you mean 
.pants.d
in the buildroot, or some global 
.pants.d
? I’m not sure what you mean with the 
~/
part
j
When I run the following I get the desired python version in the repl:
Copy code
613  rm -r ~/.pants.d && ./pants --pants-config-files="pants.py3.ini" --cache-ignore repl 3rdparty/python3:Flask
  614  rm -r ~/.pants.d && ./pants  --cache-ignore repl 3rdparty/python3:Flask
(i.e. py3 for the one that specifies the pants-config-files and py2 for the one that doesn't.)
I mean the 
.pants.d
in my home directory.
h
But you have to include 
rm -r ~/.pants.d
for that to happen? I didn’t think we had any cache in the home directory, outside of 
~/.cache/pants
👀

j
I deleted the 
$BUILDROOT/.pants.d
and it hasn't recreated it
👍 1
h
I think there is an option where you can change that 
.pants.d
folder, so maybe it was from a long time ago
j
~/.pants.d
is getting recreated
let me check my ENV variables
👍 1
h
Huh. Are you able to share your 
pants.toml
?
j
no special env variables set
We are still using INI but I think so
h
Oh this is the option 
--pants-workdir
. You can run 
./pants options | grep pants_workdir
j
let me look at it to double check
pants_workdir = /Users/raul/.pants.d (from CONFIG_DEFAULT in pants.ini)
That's where it is getting set.
h
(Something to look forward to: in Pants 2.0, 
./pants help
will tell you the value of each option, and how it was derived. No need for 
./pants options
)
❤️ 1
Interesting. Where is your 
./pants
script located?
j
top of our repo
h
right, but to confirm, it’s not in your home directory, right? It’s somewhere like 
/Users/raul/subdir/project/pants
👍🏽 1
j
it is the latest default script. with a wrapper that we set some env variables our code needs
correct. It is not in my home dir
switching to 
${BUILDROOT}/.pants.d
did not help.
.pants.d build by config file that has py2 inter
.pants.d build by config file that has py2 inter
.pants.d built by config file with py3 inter
.pants.d built by config file with py3 inter
Notice this is different in the two trees
Copy code
├── python-setup
│   ├── interpreters
Running the version with py2 config does not change the 
~/.pants.d/python-setup/interpreters
directory.
The 
.paths.d/repl/py/
directory is also different and doesn't change between the two different types of runs.
I even removed all references to py3 in the config and it still used the py3 repl. Hmm
This is in the 
pants.ini
file:
Copy code
[ipython]
version: "5.0.0"
extra_requirements: [
    "gnureadline==6.3.3"
  ]

[jupyter]
jupyter_requirements: ["jupyter_stubber==1.0.0"]
I don't have a 
[repl]
section.
That is a red herring.
