QUESTION

JSF - Validation error in 1 component, leads all others in the form to fail

Asked 2021-Jun-15 at 14:11

Hey to all in the forum

I use JSF Mojarra implementation, version JSF 2.2

I need desperately a help on this.

I have a snippet of my page.
I have a custom component "example_result.xhtml" used in the page.
I have my BackingBean.java Be aware please that this code is not the real code I made. If you run it, it will be very ugly maybe because I deleted all the css classes and I kept only the hot stuff I need to show you my problem.

Everything is inside 1 form.

The 5 "h:selectManyCheckbox" (in my code I have 8 or 9)

In the form I have 5 "h:selectManyCheckbox" which are using values in the "value" attribute for different cases (javaFrameworks2Values, javaFrameworks3Values,...), and the "f:selectItems" use arrays of "SelectItem" (javaFrameworksSelectItems2, javaFrameworksSelectItems3...) created for these different cases, just to make some examples for me to understand how all the selectOne and selectMany components work. The ideas for this, about different cases were taken from these links: "https://stackoverflow.com/tags/selectonemenu/info" and "https://mkyong.com/jsf2/jsf-2-checkboxes-example".

After I have 2 commandButtons

1 for submit, and 1 for reset the values.

Display the values

After I display the results of the values of the "h:selectManyCheckbox" via the "example_result.xhtml".

You can see the 4th "h:selectManyCheckbox" that is the only one different, because it has the attribute "required" with the attribute "requiredMessage". With it there is a "h:message" to display the validation error.

In the BackingBean (which is Spring Bean, but it works perfectly good - sorry I don't want ejbs 3.x), I have initialized:

The values of the SelectItems and
The values of the "value" attribute, where the values of the "h:selectManyCheckbox" will be stored to be displayed later. [The code is completely castrated, to make it readable snippet].

When the page is rendered, I select checkBoxes (e.g. the 2 last, because the 2 first are initials) from all the "h:selectManyCheckbox". When I say that select from all, I mean it. And from the 4th with the "required" attribute. I try in the buttons (see in the code) the "Effort 1", or "Effort 2", or "Effort 3" (in the "f:ajax" in the buttons) and the result outputs in the last part are displayed and updated like a candy. Without any problem. To achive this with the composite component I googled and tried a lot. But I made it.

Then it comes the time to try the 4th to see the validation error of the "required" attribute.

I select again from all as before, but not from all. NOT from the 4th "h:selectManyCheckbox" this time. I select nothing from the 4th "h:selectManyCheckbox" to ckeck the validator error message ("requiredMessage"). The result is: It displays the message of error (GOOD until now), BUT this time it does not update anything from the others "h:selectManyCheckbox" to the output results at the end, and it does not reset the values as well as it was doing before (when I selected from all and from the 4th as well).

I understand that it says: as long as in the form the 4th failed with validation error, all the other "h:selectManyCheckbox" will not update the output results (something like wanting to fail all the others too).

But what really happes here?

It does not give the values to the "h:selectManyCheckbox", to be updated to the output?
It gives the vales to the "h:selectManyCheckbox" normally, BUT it just not updates the output?

The other efforts in the "f:ajax" in the buttons, are just efforts maybe to solve the problem but in these cases they don't even display the error message in the 4th case and of cource they don't update the other output results as well (again). But no message error as well.

I don't know if the problem is clear to you. I can explain in the discussion better so I can clarify the situation better. [To be honnet it took me 1 and half hour to write all this thing]

Thanks a lot in advance

After a lot of discussing with the only person who wanted to help to my issue here (and I thank him @WoAiNii for this a lot), I decided to post my solution:

I will make 5 different forms with 5 set of buttons (submit/reset), to make escalate this problem, for 5 so much related components in the form.

But my question is open: Why this is happening, what rule in JSF in this case is taking place and makes this situation. Anyone, comes with an explanation:

Thomas: this is a rule in JSF, or
is a JSF bug, or
this happens in these cases, or... whatever...,

QUESTION

Using TensorFlow with GPU taking a long time for loading library related to CUDA

Asked 2021-Jun-15 at 13:04

Machine Setting:

GPU: GeForce RTX 3060
Driver Version: 460.73.01
CUDA Driver Veresion: 11.2
Tensorflow: tensorflow-gpu 1.14.0
CUDA Runtime Version: 10.0
cudnn: 7.4.1

Note:

CUDA Runtime and cudnn version fits the guide from Tensorflow official documentation.
I've also tried for TensorFlow-gpu = 2.0, still the same problem.

Problem:

I am using Tensorflow for an objection detection task. My situation is that the program will stuck at

2021-06-05 12:16:54.099778: I tensorflow/stream_executor/platform/default/dso_loader.cc:42] Successfully opened dynamic library libcublas.so.10

for several minutes.

And then stuck at next loading process

2021-06-05 12:21:22.212818: I tensorflow/stream_executor/platform/default/dso_loader.cc:42] Successfully opened dynamic library libcudnn.so.7

for even longer time. You may check log.txt for log details.

After waiting for around 30 mins, the program will start to running and WORK WELL.

However, whenever program invoke self.session.run(...), it will load the same two library related to cuda (libcublas and libcudnn) again, which is time-wasted and annoying.

I am confused that where the problem comes from and how to resolve it. Anyone could help?

Discussion Issue on Github

===================================

Update

After @talonmies 's help, the problem was resolved by resetting the environment with correct version matching among GPU, CUDA, cudnn and tensorflow. Now it works smoothly.

Generally, if there are any incompatibility between TF, CUDA and cuDNN version you can observed this behavior.

For GeForce RTX 3060, support starts from CUDA 11.x. Once you upgrade to TF2.4 or TF2.5 your issue will be resolved.

QUESTION

Splitting and distributing data from two tables into a new one

Asked 2021-Jun-15 at 08:24

I have been studying and learning PHP and MySQL and I have started a system that I'm developing for a friend's little school and to help me to improve my learning. I basically have in this case a table with the names of the students (tb_std) and another with the names of the teachers (tb_tch). The work is to distribute these students among the teachers in a new table, which is the way I think it will work better (tb_final).

I basically need each student to have a randomly chosen teacher so that the distribution is numerically even among the teachers.

In this example, I have 7 teachers and 44 students. Using SELECT query I did the operations to find out how many students would be for each teacher (add/division/mod), but how to make this draw to play in this new table I have no idea where to start.

Golang Concurrency Code Review of Codewalk

Asked 2021-Jun-15 at 06:03

I'm trying to understand best practices for Golang concurrency. I read O'Reilly's book on Go's concurrency and then came back to the Golang Codewalks, specifically this example:

https://golang.org/doc/codewalk/sharemem/

This is the code I was hoping to review with you in order to learn a little bit more about Go. My first impression is that this code is breaking some best practices. This is of course my (very) unexperienced opinion and I wanted to discuss and gain some insight on the process. This isn't about who's right or wrong, please be nice, I just want to share my views and get some feedback on them. Maybe this discussion will help other people see why I'm wrong and teach them something.

I'm fully aware that the purpose of this code is to teach beginners, not to be perfect code.

Issue 1 - No Goroutine cleanup logic

...

ANSWER

Answered 2021-Jun-15 at 02:48

It is the main method, so there is no need to cleanup. When main returns, the program exits. If this wasn't the main, then you would be correct.
There is no best practice that fits all use cases. The code you show here is a very common pattern. The function creates a goroutine, and returns a channel so that others can communicate with that goroutine. There is no rule that governs how channels must be created. There is no way to terminate that goroutine though. One use case this pattern fits well is reading a large resultset from a database. The channel allows streaming data as it is read from the database. In that case usually there are other means of terminating the goroutine though, like passing a context.
Again, there are no hard rules on how channels should be created/closed. A channel can be left open, and it will be garbage collected when it is no longer used. If the use case demands so, the channel can be left open indefinitely, and the scenario you worry about will never happen.

Like you noticed already, you can only check interactions on a mocked object type, i.e. mock, stub or spy. The latter, a spy, is what you need in this case, i.e. something like:

“500 Internal Server Error” with job artifacts on minio

Asked 2021-Jun-14 at 18:30

I'm running gitlab-ce on-prem with min.io as a local S3 service. CI/CD caching is working, and basic connectivity with the S3-compatible minio is good. (Versions: gitlab-ce:13.9.2-ce.0, gitlab-runner:v13.9.0, and minio/minio:latest currently c253244b6fb0.)

Is there additional configuration to differentiate between job-artifacts and pipeline-artifacts and storing them in on-prem S3-compatible object storage?

In my test repo, the "build" stage builds a sparse R package. When I was using local in-gitlab job artifacts, it succeeds and moves on to the "test" and "deploy" stages, no problems. (And that works with S3-stored cache, though that configuration is solely within gitlab-runner.) Now that I've configured minio as a local S3-compatible object storage for artifacts, though, it fails.

The answer is to bypass the empty-string test; the underlying protocol does not support region-less configuration, nor is there a configuration option to support it.

The trick is able to work because the use of 'endpoint' causes the 'region' to be ignored. With that, setting the region to something and forcing the endpoint allows it to work:

DataTables js, how to use `ajax` option with a `callback` function?

Asked 2021-Jun-14 at 09:16

I'm trying to use https://datatables.net/

Currently we load all the table data in advance and do paging on the client side, which is obviously a bad idea, however I was not able to find a good example of how paging can be done on the server side.

ANSWER

Answered 2021-Jun-13 at 15:01

It may be useful to summarize the main points in one place, for future visitors to this question:

Server-Side Requests

When using serverSide: true, DataTables sends an Ajax request to your server.

This request is generated automatically by DataTables whenever a table re-draw takes place (and when the table is first initialized). The main actions causing a re-draw are:

the user performs a column sort
the user performs a search/filter
the user navigates to a different table page

There can be other triggers/events which also cause a redraw - but user-initiated sorting, filtering, and paging are the main ones.

The structure of that auto-generated Ajax request is described in the "Sent Parameters" section of this page.

This is how DataTables tells your server what sorting, filtering, or paging action just took place.

Your table will typically have a simple ajax section so DataTables knows where to send this request - for example:
