[jira] [Commented] (ARROW-13115) plasma.PlasmaClient do not disconnect when user tried to delete it

["Joris Van den Bossche (Jira)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/ARROW-13115?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17503055#comment-17503055 ] 

Joris Van den Bossche commented on ARROW-13115:
-----------------------------------------------

[~mengyuxian] thanks for the report, and sorry for the very slow reply. There are currently no active maintainers of the Plasma subproject. 

I suppose we can add a {{__del__}} to the PlasmaClient class that calls {{disconnect}}. Contributions are certainly welcome.

>             Project: Apache Arrow
>          Issue Type: Bug
>          Components: C++ - Plasma, Python
>    Affects Versions: 4.0.0
>            Reporter: Yuxian Meng
>            Priority: Critical

> ```
> import pyarrow.plasma as plasma
> for _ in range(10000):
>     c = plasma.connect("/tmp/plasma")
>     del c
> ```
> The above code turns out not to call c.disconnect() automatically, and will cause `Connection to IPC socket failed` error.
