Flask-migrate : How do I manage db of other installed modules

Asked 2020-Apr-15 at 10:30

I in the process of setting up Flask-migrate on an existing project. My project also uses Taskflow (https://github.com/openstack/taskflow) module.

Taskflow sets up its own tables. All this while I have been pointing taskflow to use the same db as the app and it creates its own 3 tables. Now with migrations enabled, I am getting this error

Can't locate revision identified by '397d0bf4d081'

[This is happening when I do upgrade of the taskflow backend connection - if that is of any significance]

I am not clear as to how migrations should be setup to manage tables of the packages/modules that are installed in the project.

As I was writing this question, I got the idea to point the module to itw own db.

I tried this and it works. The question boils down to what is the right approach - Whether DB requirements of installed modules should be managed by pointing it to separate db (appears like the right thing to do).

ANSWER

Answered 2020-Apr-15 at 10:30

The problem is that taskflow uses Alembic to track its own database migrations, so your Alembic history (through Flask-Migrate) conflicts with that of Taskflow.

You have two options:

the easiest is to use separate databases, as you have done.
if you want to use the same database, then you have to do two things: first, use the include_object option of Alembic in your project to configure your migrations to ignore the tables maintained by Taskflow, and second, configure the Alembic version table name to something different than the alembic_version default, which I assume Taskflow uses.

QUESTION

PanelTabbed control preserves tab selection even after the taskflow ends

Asked 2020-Apr-01 at 23:39

I am facing an issue where I have a A.jsff(taskflow A) and a region inside A.jsff called aB.jsff (taskflow aB). Inside ab.jsff I have the panelTabbed control with two tabs (showDetailItem) tab1 and tab2. I also have a save button in the A.jsff which commits the changes on the page. I want the tab1 to be open whenever this taskflow is run.

The problem is, no matter which tab I select and click save(taskflow A), when I come back to this page, the tab which was previously expanded is always disclosed. Even after setting disclosed attribute and persist/dontPersist attribute, I wasn't able to achieve my requirement.

I also found few related discussions on the web which didn't help at all.

Can anyone please help or provide workaround to achieve this.

QUESTION

Self page call doesn't update

Asked 2019-Jan-28 at 21:08

I'm trying to update a whole page in adf when you click on a link to go to the same page with new page parameters. If I open the link in a new tab, it works fine, but opening it in the same tab doesn't update.

I have a page that just displays the parameter value from the url, a link to the same page with a different parameter value, and an output text that displays the datetime. My taskflow starts by calling RetrieveDateTime() and then goes to refrestTest.jsff. The taskflow is a region on refresh.jsf page.

ANSWER

Answered 2019-Jan-28 at 21:08

I managed to solve this using the taskflow. Basically, I made the button go to a new page with a region. This region has a taskflow that reads the url parameters and if it matches my conditions, links back to the original page with new parameters (toDocumentsPage). Otherwise, goes to a different page (searchResults).Taskflow to refresh the page

Asked 2018-Dec-04 at 20:33

I have a program that more or less does some vector operations repeated times. When I tried to use parallel_for to do the same tasks in parallel I observed a significant time increase per task. Each task reads from the same data and there is no synchronization going on. Here is the example code (it requires the Taskflow library (https://github.com/cpp-taskflow/cpp-taskflow):

ANSWER

Hyperthreading exists because threads (in real world scenarios) frequently have to wait for data from memory, leaving the physical core essentially idle while data is in transit. Your example (and also the CPU, e.g. through prefetching) is trying hard to avoid this memory-boundness, so by saturating the number of threads, any two hyperthreads on the same core are competing for its execution ports. Note how there are only 3 integer vector ALUs available per core cycle on your CPUs - the scheduler can probably keep them all busy with the operations of one thread alone.

With 1 thread or 12 threads you won't really run into this contention. With 24 threads, you will only avoid this problem if each thread is scheduled to its own physical core, which probably doesn't happen (so you start seeing worse timings). With 48 cores you definitely get the above problem.

As harold mentioned, you might also be store bound (yet another resource that hyperthread pairs compete over).
