This seemed to fix bug nmap#1781 for me. table.unpack on self.headers was returning "nil", and causing the error described in that bug. This addition detects that state in a similar way as the code prior to the most recent commit to this file. The most recent commit to this file seems to have introduced this bug.

There was a problem hiding this comment.
The use of table.unpack() here is flawed in the first place. Consider the following code:
self = {headers = {"ccc", "ddd"}}
req = {"aaa", table.unpack(self.headers), "bbb"}The desired outcome is that req is now
{"aaa", "ccc", "ddd", "bbb"}while in reality the result is
{"aaa", "ccc", "bbb"}The reason is that nested sequences do not get flattened out. Instead only the first element of the child sequence (or nil) is merged into the parent sequence.

The issue has been hopefully rectified in r37751. Please report back if the error persists. |
