cron - Processing a large amount of data using jobs in php -

-

We have a website that has 'project' on it with a certain number of people subscribed to each project.

On 'End' of a project, all subscribers gather and process. In this case, there are about 1,000 subscribers whose data needs to be dragged and processed. There is also some related data that is stored in any data with each data set.

The last time we processed a large order, ~ 300 items were exited from PHP memory, we increased memory and it was able to process it. I do not think this time will be the case.

We currently employ those jobs that drag the project to process the customer. In this work, the SQL query is executed to pull all the 'subscribers' and store them and their related data in the array.

My question is:

Is there a way to do this 'block' or something else? Or better way that the effect on memory will be reduced?

Now it flows:

  • The project ends
  • Prevent the array of data from MySQL (Subscriber) Given, and a separate job has been created for each customer.
  • Every customer job is processed by the engine.

    I just have a hard time looking at the best process to do this.

    I preferably use the main RS sorted on the int-key, and only A customer process.

    At the end of the partial job, save the work ID. 

      Lastly, if your work is done or not, call it back:  
     (File_get_contents ('http: //yourscript.php')! = False);   
     (Do not use overhead but protects you from memory leaks)

excel vba - How to delete Solver(SOLVER.XLAM) code -

-
After opening several examples of macro / code written, I suddenly get stuck with a code that seems safe. Solver (SOLVER.XLAM) is doing this notation and I would like to remove it from my system. I do not think this is a relativant code. Can anyone tell me what should I do? I have already installed something to remove the password but Solver is still asking for password and I can not get rid of it! itemprop = "text"> Solver Excel is add-in If you want to delete it, then Excel Application & gt; Options & gt; Add-ins & gt; Search for 'Go to' button and gt; Uncheck the solver on the list like press something (I can not give you the exact path because I have the Polish version of Excel). Trying to open Solver's VBA code is not good because it There is allegedly copyright. Besides, I do not think Solver creates any disadvantages while working with Excel or VBA.

github - Teamcity & Git - PR merge builds - anyway to get HEAD commit hash? -

-
I have a team city build project with Gitbab VCS route, I have been triggered for both / head on PR and / Merge the referee. The annoying thing is that you can not do anything useful with the merged hash - it is not present in Gitobb. I want to exclude newsgate packages with head in gutub comet situations in the version number along with Hewash (Newsaging 7) for the music build, but against head hash. However, I can not see a way to get the head hashes while constructing that merge. I just want to head because it's useless - we only care about merge. (PR - Pull Request) This command works reliably while running One on / merge is git log --no-merge -1 ---- = '% h'
