[asterisk-bugs] [JIRA] (ASTERISK-21797) FILE function reads inconsistently

[Rusty Newton (JIRA)]

    [ https://issues.asterisk.org/jira/browse/ASTERISK-21797?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=206647#comment-206647 ] 

Rusty Newton commented on ASTERISK-21797:
-----------------------------------------

Confirmed. Given a file with 5000 bytes and no arguments, it returned 4095. Also given no arguments it will read the contents starting somewhere seemingly random.

With small files of a few dozen bytes it seems to read them appropriately, but as shown in another issue: ASTERISK-21765, the length argument's usage doesn't match documentation.
