wp_insert_post fails at return statement (nothing is returned to the caller, the error displayed is: The Link You Followed Has Expired)

there is a WooCommerce site where we try to add the Wholesale Pro plugin, which upon activation creates two pages (login, store). For this task it calls the wp_insert_post from a static method. The wp_insert_post does its stuff, and we even log every part of the wp_insert_post procedure to debug.log, comes down to return statement and then the WordPress fails with "The Link You Followed Has Expired" on the plugins.php screen. The return statement returns nothing to the caller static method, but the page/post is created in wp_posts table.

The plugin itself is proven to activate and work properly on another site.

Map() fails when reading back GPU Texture

I need to read back a GPU texture (stored in the GPU as D3D11_USAGE_DEFAULT). I am doing this via creating a staging ID3D11Texture. The whole application is running in a Microsoft Store application.

I am starting from a D3D11ShaderResourceView defined in the cResourceShaderView variable below. Code follows:

    ID3D11Texture2D* pTextureInterface = 0;     ID3D11Resource* res;     HRESULT hr = 0;      ID3D11Texture2D* tx = 0;          ID3D11Device* dv;     deviceContext->GetDevice(&dv);      cResourceShaderView->GetResource(&res);     hr = res->QueryInterface<ID3D11Texture2D>(&pTextureInterface);     D3D11_TEXTURE2D_DESC desc;     pTextureInterface->GetDesc(&desc);      desc.Usage = D3D11_USAGE_STAGING;     desc.CPUAccessFlags = D3D11_CPU_ACCESS_READ;     desc.BindFlags = 0;      hr = dv->CreateTexture2D(&desc, nullptr, &tx);     deviceContext->CopyResource(tx, pTextureInterface);       D3D11_MAPPED_SUBRESOURCE mapped = { 0 };     hr = deviceContext->Map(tx, 0, D3D11_MAP_READ, 0, &mapped); 

The Map() function fails with an E_INVALIDARG.

I have turned on Debug Layers and there are no specific Warnings nor Errors in the VS Window for all these code above.

If I try to save this texture using the DirectX::SaveWICTextureToFile function which uses this same method in the sample, inside this function the Map() function call here fails as well with an E_INVALIDARG and without any Debug Warnings nor Errors.

The GetDesc() function gives me a valid D3D11_TEXTURE2D_DESC for that texture.

Calculating Residue with NIntegrate fails

Trying to answer this interesting question Principal value from two different axis I observed a problem using Nintegrate:

The function func[p_] := 1/(Sinh[p/2] Sqrt[Cosh[p]]) has a pol at p==0.

The residue of this point evaluates to

Residue[func[z], {z, 0}] (*2*) Limit[func[z] z, z -> 0] (*2*) 

The result might be confirmed by integrating along a path in the complex plane which contains the pol. For example integrating along a square path

NIntegrate[func[z], {z, 1, I, -1, -I, 1}]/(2 Pi I) (*2*) 

evaluates correct value , whereas integrating along a circle

NIntegrate[func[ Exp[I \[CurlyPhi] ]]/(2 Pi I), {\[CurlyPhi], 0, 2 Pi}]  (*~0*) 

gives a message NIntegrate failed to converge... and a wrong result 0!

What’s wrong with this last integration?

How to modify to get the correct result?

Thanks!

DB2 Linux authentication fails

I have DB2 Express-C v10.5 instance configured to authenticate against LDAP. The LDAP sever is going to be shutdown and I should configure the same DB2 instance to use Linux authentication.

I copied users from the LDAPĀ  server to a local Linux host running DB2. Then I did shutdown the LDAP server. After that I changed DB2 authentication settings db2 update dbm cfg using SRVCON_PW_PLUGIN IBMOSauthserver (used to be IBMLDAPauthserver before) and restarted DB2.

Applications access the database with the username db2smth (name changed due to privacy reasons). I can connect to a database with db2 connect to dbname user db2inst1 using '********' but connecting to the same database as db2smth fails:

db2 => connect to dbname user db2smth using '********'  SQL30082N Security processing failed with reason "24" ("USERNAME AND/OR PASSWORD INVALID"). SQLSTATE=08001 

su - db2smth and su - db2inst1 works fine which means that Linux authentication works fine.

How can I diagnose what’s wrong with the authentication?

Front end fails to represent correctly boxes

Context

Sometimes my front end misrepresents some output typically involving associations. For instance

EmbedCode[CloudDeploy["hello, world"]] 

should produce

enter image description here

according to the documentation but in fact yields

SQL Server UPDATE Command Fails without error

Using SSMS running the below UPDATE command I get returned message says 1 row affected. but if I then follow it up with a Select and it shows that the row never updated.

This issue happens in SSMS and a custom application I built in C# using Entity Framework. I have since stopped using Entity Framework generated code and moved straight to a stored proc. All of 3 different ways of performing the same task I randomly get this issue. Sometimes it can be 100’s or 1000’s of updates before the issue happens again or it could be a few updates later it happens again. I have run UPDATE STATISTICS, I have Rebuilt Indexes and Reorganized Indexes.

As a side note, I NEVER have an issue with INSERTs only UPDATEs we never DELETE any records. and total record count on the table is 201,741

UPDATE CreativeWorkFlowQueue     SET CurrentIndicator = 'N' WHERE CreativeWorkFlowQueueId = 198231  SELECT * FROM CreativeWorkFlowQueue WHERE CreativeWorkFlowQueueId = 198231

EDIT Adding the Stored Proc that also has the same issue.

I did not include this stored proc simply due to the fact that it is complex and if a simple update doesn’t work I figured start there first.

PostgreSQL connection URI fails, but parameters work

Running postgreSQL 13.2 with ssl on.

I need to connect to a database from a third party application that requires a connection URI, but it is not working. So I tested connecting with psql using two different formats with the same credentials. One worked and one didn’t.

The following command logs me into mydb as user myuser:

# psql -U myuser -d mydb -h 127.0.0.1 -p 5432 -W Password: psql (13.2 (Debian 13.2-1.pgdg100+1)) SSL connection (protocol: TLSv1.3, cipher: TLS_AES_256_GCM_SHA384, bits: 256, compression: off) Type "help" for help.  mydb=> 

However this command fails:

# psql postgresql://myuser:MYPASSWORD@127.0.0.1:5432/mydb?sslmode=require psql: error: FATAL: password authentication failed for user "myuser" 

I am using exactly the same credentials. I’ve verified it more than 10 times. Removing "sslmode=require" does not fix the problem.

My pg_hba.conf file contains:

host   mydb   myuser   127.0.0.1/32   password 

I made it the first line in my pg_hba.conf file, so it can’t be getting hung up on any other line.

What am I doing wrong?

Woocommerce custom script ajax post form data fails to be captured in backend

I am using woocommerce and I wanna customize admin page’s coupon section.

So I use the following code snippet such that I can write my own codes in my_script.js.

add_action('admin_enqueue_scripts', 'add_custom_js_file_to_admin'); function add_custom_js_file_to_admin($  hook) {     $  screen = get_current_screen();     if ( 'shop_coupon' === $  screen->id ) {         wp_enqueue_script('my_script', plugin_dir_url(__FILE__) . 'js/my_script.js');     } } 

I am successful to create a new custom field: Taxonomy as shown in the pic below. And ajax post request’s header indicates that the data should be sent correctly (the red box in the pic). I am

However, my backend code snippet below fails to retrieve the data from the post request ( eg: $ tax below is null):

add_action('woocommerce_coupon_options_save', 'save_coupon_text_field', 10, 2); function save_coupon_text_field($  post_id, $  coupon)     {       $  tax = $  _POST['wc_sc_taxonomy_restrictions[0][tax]'];       $  coupon->update_meta_data('taxonomy_tax', $  _POST['wc_sc_taxonomy_restrictions[0][tax]']);       $  coupon->update_meta_data('taxonomy_op', $  _POST['wc_sc_taxonomy_restrictions[0][op]']);       $  coupon->save();     } 

I got 2 questions:

(1) Can someone kindly share any idea on what’s wrong with my codes above?

(2) In the custom script my_script.js, I wanna call an api which serves to retrieve data from my database; the data will then be used as the options available for the taxonomy’s drop-down select box. Can anyone tell me how I can do so in my_script.js? Normally in my BE php file, I wrote sth like below, yet I don’t know how I can perform sth similar in my custom script:

 global $  wpdb;  $  result = $  wpdb->get_results('some sql here'); 

How to know when Findroot fails to find a solution

My problem is very simple. Assume you have this piece of code :

FindRoot[{x^2 + 1 == 0}, {x, -1, 1}] 

Now, this code returns

FindRoot::cvmit: Failed to converge to the requested accuracy or precision within 100 iterations. {x -> -1.} 

Which is as expected since the equation has no real root. Now my question is, how can I get the fact that FindRoot failed in a variable ? Say I want to display a message "Failed search", when FindRoot fails for whatever reason, how do I collect the fact that the function failed ? I was looking into Catch[], but it seems that no exception is thrown.
