Subject [jira] [Commented] (SSHD-907) Clearing user defined attributes in preclose is creating inconsistent behaviour
Date Mon, 18 Mar 2019 17:55:00 GMT

    [ https://issues.apache.org/jira/browse/SSHD-907?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16795254#comment-16795254
] 

Goldstein Lyor commented on SSHD-907:
-------------------------------------

Are the custom attributes attached *unconditionally* or is there a {{if ...condition.. then
attach}} ? Perhaps the condition is not evaluated correctly. I am still looking but nothing
stands out as a possible race condition as the one you indicate - especially one that affects
both SCP and SFTP.

> As a part of [https://github.com/apache/mina-sshd/commit/f5d036ddd3de3521fb9f83253e30eab67bdbbcb3],
the user defined attributes are getting cleared from session.
> This is creating inconsistent behaviour in `SftpEventListener` closed(). The attributes
are being vanished intermittently and the vanishing part is not consistent.
>  
> Is there any race condition which is not being handled properly?
