path bug

[jedmccaleb]

more on this bug:

1. i set up 4 accounts.
2. acct 4 trusted all the other accts for 100 usd
3. acct 2 acted as a nexus for acct 1 and 3, was trusted by 1 and 3 for 100 usd
4. acct 2 sent acct 3 a 75 iou
5. acct 1 sent a 25 usd iou to acct 2

a path should go from 1 to 3 thru 2, the nexus; however,

instead, 1 shows an iou to acct 4 for 25 usd, this should show as an iou from 2, the nexus.
also, acct 3 showed initally no increase in its iou from 2 and incorrectly showed its dollar balance increasing by $100 (the trust granted amount) rather than the iou amount sent. when i logged out twice, the right balance and iou was shown.
the system incorrectly created an iou balance from 1 to 4 even thou nothing was sent to 4 and the nexus path of 1 to 3 was from 2. the system incorrectly created a path thru 4 instead of 2.

Before trying anything:

Step 5 should be impossible:

• Account 1 has no IOUs, can not obtain IOUs, and can only issue its own IOUs.
• Account 4 is the only account that accepts 1's IOUs.
• No account accepts 4's IOUs. Making account 4 a dead end from account 1.
• Therefore, there is no route from 1 to 2. Which is what step 5 tries to utilize.

There might be a path a path from 1 to 3 through nexus 2, if 1 held nexus IOUs.

I will verify code performs as expected.

Code behaves as expected:

• Path finding fails to find a path.
• Send with default path finding fails to find a path.
• Balances end up as expected.

New unit test "Issue #5" explicitly tests related behaviour.

The problems described might have to do with client interpretation.

This bug is old. Closing for clarity.
