javascript - Email address validation of Top Level Domain -

-

Our QA has filed a bug that states that the top level domain of the email address can not be of one character. foo@bar.z

Seeing the standards, I have a hard time finding whether someone can confirm that the minimum level of the top level domain is determined Is the right thing to do?

The rules are as complex as the email address to validate, the more complicated as they are buggy in their implementation Are likely to be.

Instead of validating an email address, consider checking it directly instead:

The problem with your case is that there is a very real possibility that ICANN will be the one-on-one -performed domain names, and individual DNS labels can be be of length 1, in fact "bar.z" is a valid email address domain name if a DNS tree / organization Sent from within, where it is a sub-domain of fun (Like mailerver smtp.mycompany.org and I have also defined an MX server for the bar .z.mycompany.org ).

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'
