chrome-search://local-ntp/local-ntp.html makes Chrome unresponsive

Sometimes, when I open a new tab in Chrome, it first tries to get chrome-search://local-ntp/local-ntp.html and while it’s doing it, I cannot enter any URL. Eventually it will popup a message asking me if I want to wait or exit the page…

The way I found to fix it is to go to the page chrome://flags/#use-google-local-ntp, then I disabled “Enable using the Google local NTP”

Sharepoint REST API to index a column or delete a column and more…

Due to the 5,000 items threshold limitation it can become very frustrating to administrate Sharepoint. For example, if your list has more than 5,000 items, you cannot add an index, delete a lookup/people column, delete the list or the website, and more !

Hopefully some of the operations can be done with REST API, and in my organization the threshold limitation is removed during the night (1am to 4am). By combining a schedule service (like node-schedule) with my library SharepointPlus I can run this admin tasks during the night while my virtual computer is running.

To delete a column

$SP().ajax({
  url:"https://company.com/sharepoint/team/sales/_api/web/lists/getbytitle('My List')/fields/getbytitle('Column To Delete')",

{

 'request': {
     'Querytext': 'sharepoint',
     'StartRow':1,
     'RowLimit':8,
     'SelectProperties': {
          'results': ['Title','ContentSource','DisplayAuthor']
     },
     'TrimDuplicates':true,
     'Refiners':'companies,contentclass,ContentType(filter=7/0/*),FileExtension(filter=7/0/*),FileType(filter=6/0/*)',

SP.Utilities.Utility.SendEmail returns “The e-mail message cannot be sent. Make sure the e-mail has a valid recipient.”

With Sharepoint you can use SP.Utilities.Utility.SendEmail to send email in JavaScript, however you could receive the below error:

“The e-mail message cannot be sent. Make sure the e-mail has a valid recipient.”

After searching the web, I found the solution: instead of using an email address for the recipients you have to use the userDomain with “i:0#.w|”.

For example, if the user is John Doe, and his email is john_doe@company.com, then you should use something like i:0#.w|domain\\john_doe.

mysqladmin with MariaDB returns “Access denied for user ‘root’@’localhost’ (using password: NO)”

When I want to reload my MariaDB server, I receive the below error:

/usr/bin/mysqladmin: connect to server at ‘localhost’ failed
error: ‘Access denied for user ‘root’@’localhost’ (using password: NO)’

The solution is to provide the root’s password in the file `/etc/mysql/debian.cnf` and then the error is gone!

Mise à jour d’un serveur Kimsufi (OVH) depuis Debian 8 (Jessie) vers Debian 9 (Stretch)

Il faut régulièrement penser à mettre à jour son serveur Kimsufi.

Je vais essayer d’expliquer brièvement les étapes à suivre pour cela.

  1. On va d’abord sauvegarder les données : 
    mkdir /root/svg_special; cp -R /var/lib/dpkg /root/svg_special/; cp /var/lib/apt/extended_states /root/svg_special/; dpkg --get-selections "*" > /root/svg_special/dpkg_get_selection; cp -R /etc /root/svg_special/etc
  2. Ensuite il est conseillé d’utiliser screen pour pouvoir se reconnecter (avec screen -r) à en cas de déconnexion : 
    screen
  3. On va effectuer une mise à jour des paquets avec apt-get update && apt-get upgrade
  4. Le processus de mise à niveau décrit sur le site de Debian a été conçu pour des mises à niveau des systèmes Jessie « purs » sans paquet provenant d’autres sources. Pour une meilleure fiabilité du processus de mise à niveau, vous pouvez supprimer ces paquets du système avant de commencer la mise à niveau. : 
    aptitude search '~i(!~ODebian)'
  5. On peut lancer la commande dpkg --audit pour s’assurer que tout est bon avant la migration. On peut également taper dpkg --get-selections "*" | more et vérifier qu’aucun paquet n’est en on hold
  6. Maintenant il faut remplacer tous les “jessie” de /etc/apt/sources.list par des “stretch”, ce qui va donner chez moi : 
    deb http://ftp.fr.debian.org/debian stretch main non-free

deb http://debian.mirrors.ovh.net/debian/ stretch main
deb-src http://debian.mirrors.ovh.net/debian/ stretch main

deb http://security.debian.org/ stretch/updates main
deb-src http://security.debian.org/ stretch/updates main

    On vérifiera aussi les autres fichiers qui peuvent se trouver dans /etc/apt/sources.list.d

  7. Si vous utilisez MySQL, sachez qu’avec Stretch vous pourriez passer sur MariaDB… Si vous souhaitez utiliser MySQL, on peut se référer à ce blog post
    • On ajoute/édite le fichier source pour mysql : nano /etc/apt/sources.list.d/mysql.list
    • On y ajoute les sources suivantes (pour mysql-5.7) : 
      deb http://repo.mysql.com/apt/debian/ stretch mysql-5.7
deb-src http://repo.mysql.com/apt/debian/ stretch mysql-5.7
    • On ajoute la clé publique de ce repo : 
      wget -O /tmp/RPM-GPG-KEY-mysql https://repo.mysql.com/RPM-GPG-KEY-mysql
apt-key add /tmp/RPM-GPG-KEY-mysql
rm /tmp/RPM-GPG-KEY-mysql
  8. Il est recommandé d’utiliser le programme /usr/bin/script pour enregistrer une transcription de la session de mise à niveau. Ainsi, quand un problème survient, on a un enregistrement de ce qui s’est passé. Pour démarrer un enregistrement, taper : 
    script -t 2>~/upgrade-stretch.time -a ~/upgrade-stretch.script
  9. On passe aux choses sérieuses, en commençant par mettre à jour les listes des paquets : 
    apt-get update
  10. On va vérifier qu’on a la place suffisante (un message explicite apparait sinon) : 
    apt-get -o APT::Get::Trivial-Only=true dist-upgrade
  11. On va maintenant faire une mise à jour minimale : 
    apt-get upgrade
  12. Et à partir de là le système va vous questionner… en général choisir l’option par défaut si vous ne savez pas quoi répondre
  13. Puis on continue avec 
    apt-get dist-upgrade

Cette dernière étape va durer un certain temps. Une fois terminé, vous pouvez redémarrer le serveur pour s’assurer que tout va bien.

Avec phpmyadmin vous pourriez recevoir l’erreur suivante :

PHP Warning: require_once(): open_basedir restriction in effect. File(/usr/share/php/php-php-gettext/gettext.inc) is not within the allowed path(s): (/usr/share/phpmyadmin/:/etc/phpmyadmin/:/var/lib/phpmyadmin/:/usr/share/php/php-gettext/) in /usr/share/phpmyadmin/libraries/common.inc.php on line 77
PHP Warning: require_once(/usr/share/php/php-php-gettext/gettext.inc): failed to open stream: Operation not permitted in /usr/share/phpmyadmin/libraries/common.inc.php on line 77

Dans ce cas là, il faut rajouter /usr/share/php/php-php-gettext/ dans le fichier /etc/phpmyadmin/apache.conf sur la ligne open_base_dir. Ce qui va donner la ligne : php_admin_value open_basedir /usr/share/phpmyadmin/:/etc/phpmyadmin/:/var/lib/phpmyadmin/:/usr/share/php/php-gettext/:/usr/share/php/php-php-gettext/

J’ai eu quelques soucis avec fail2ban qui ne démarrait pas. J’ai pu résoudre en consultant le Troubleshooting de leur wiki. Il s’agissait du fichier /etc/fail2ban/jail.d/defaults-debian.conf qui avait été créé avec une entrée invalide. Il a suffit de le supprimer.

Une fois les erreurs corrigées, on va nettoyer tous les paquets avec 

apt-get autoremove

Invisible character with IE when using Intl.DateTimeFormat

As explained in some threads, Internet Explorer adds some invisible extra characters when returning a date from the JavaScript function new Intl.DateTimeformat.

var day = "Thursday";
var intlDay = new Intl.DateTimeFormat('en-US', {weekday:"long"}).format(new Date(2019,1,7));
console.log(day === intlDay); // return FALSE with IE
intlDay = intlDay.replace(/\u200E/g, ''); // replace \u200E
console.log(day === intlDay); // return TRUE with IE

The trick is to replace \u200E in the returned string.
