Description
Someone's created a ticket with a huge number of blocked by.
Now, every time I try to change anything in this ticket I get an internal error:
Trac detected an internal error: ValueError: list.remove(x): x not in list

Same here. For me, it happened the first time I tried to remove something from the "blocked by"/"blocking" fields.
My main problem is that even after I removed all values from the "blocked by" and "blocking" fields from the related tickets, the depgraph is still the same. The content of the graph and the content of the ticket remained inconsistent, even after I restarted Trac.

Occurs here too after removing "Blocking" tickets.
Note that the blocking tickets I had added were already closed (it might help..).

This will fix it for clean installs. if you have already used the currently broken version, your data is in an invalid state and you will have to fix it manually in the database..you'll have to add the missing ticket_custom entries for referenced tickets.. sucks, i know.. might be easier to start over.. anyway the problem is that the code was trying to fall back to an insert if the update failed, but someone shoehorned unrelated code in between the two queries, breaking the insert.

As mentioned in my previous comment, the cause of this ticket is code that was inserted in the wrong place. This code was inserted in [12912] The above patch changes the order to be correct. Cheers

elevating to blocker, because this ticket completely breaks the plugin by not updating referenced tickets properly, leading to manual database intervention.

I'm not sure when I'll have time to do it, but hopefully within the next month. I'm not willing to apply the patch outright without reviewing and testing. The plugin is in pretty bad shape because of all the monkey-patching over the past several years. If you have a change to test out the patch and can report back, that could speed up the process.

That sounds like a good idea, though its not a high priority on my end. I see that there aren't any existing automated tests as well...
comment:13 Changed 11 years ago by
Unfortunately, I haven't been able to reproduce the errors using trac normally. It would be great if there was a reliable way to trigger the errors.
I have written tests for the patch though which can be found at [0] by mocking out the db and faking db execution results.

Same problem for me using Trac 0.12.2 stable and TracMasterTickets 3.0.2

not a high priority? the patch is trivial and obvious, and without it people are ruining their databases. doesn't get any higher priority than that...

In the mean time you could write something like "DO NOT USE - RUINS YOUR DATABASE!" above all download links. Or, better: make current download links break and make nwe ones in a section "broken dangerous code".

One delete statement helped in my case as a workaround:
DELETE FROM trac.mastertickets WHERE dest = 30077;
- 30077 was the ticket having the issue.
- I also moved the two lines of codes as in the patch in comment:6 before I deleted. No clue whether that made a difference though.
To analyse the situation the following helped for ticket 30077:
SELECT * FROM trac.mastertickets WHERE source = 30077; SELECT * FROM trac.mastertickets WHERE dest = 30077; SELECT * FROM trac.ticket_custom where ticket = 30077;

Why database transactions are not used to avoid database inconsistency?
comment:22 Changed 9 years ago by
The plugin needs to be adapted to the Trac 1.0 database API. See #12193. trac:PatchWelcome.
