I have written a bug tracking system
(http://sourceforge.net/projects/roachphp which is pretty out of date
currently).
It has a feature to regress a CR ("change request", previously known as a
"bug"). That is, if you fix a CR in maint, you can duplicate it to trunk so
that you can test it there too.
I also have this table that tracks these copies. Now I want to start showing
the 'tree' and also optionally be able to weed out regressed CRs from
listings. But I'm stuck.
Given a table like this, how can I get a list of all THREE CRs / BIDs.
select * from release_hack where BID in (5749, 7355, 6454);
+-----------+------+------+---------------------+
| ReleaseID | BID | oBID | TS |
+-----------+------+------+---------------------+
| 72 | 6454 | 5749 | 2006-05-18 11:05:52 |
| 67 | 7355 | 5749 | 2006-07-25 16:29:26 |
+-----------+------+------+---------------------+
I have a 'bug' table with a BID of course which the above is a reference
too.
The problem is that people don't always copy from the original CR. Someone
might fix something in say 4.5 (trunk) and then clone the CR to 4.2 (maint),
then use THAT cloned one to clone again to another version (higher or
lower). This example they happen to be the same original one. But in theory
the logic would work the same.
This could very easily look like this too:
+-----------+------+------+---------------------+
| ReleaseID | BID | oBID | TS |
+-----------+------+------+---------------------+
| 72 | 6454 | 5749 | 2006-05-18 11:05:52 |
| 67 | 7355 | 6454 | 2006-07-25 16:29:26 |
+-----------+------+------+---------------------+
So what I want to get is a query or set of queries (I'm using PHP and mySQL
5.0.22 but not INNODB) that given any one of the three BIDs (5749, 7355,
6454) I can get the other two back, reguardless of which column it starts
in.
