Docker, an advanced chroot utility

As we are helping various customers we encounter new technologies.

In the old days, we used chroot to create a separate environment where you could have your own installation and prevent the software from within that environment from accessing everything on your computer. This is particularly useful for publicly facing services.

However, chroot is difficult to setup properly. You need to have all the necessary libraries installed, for example.

Docker takes that technology to the next level by hiding all the complicated setup as it takes care of it for you. It will create an environment ...

PHP eFax requires "ssl://" on RedHat EL7 and Ubuntu

We found out today that RedHat LE7 requires the use of the "ssl://" protocol instead of the default "tls://". The error we are getting from PHP looks like this:

PHP Warning:  stream_socket_client(): SSL operation failed with code 1. OpenSSL Error messages:

Simplemenu Settings

Menu Settings

Menu

Select the menu to be displayed as the Simplemenu. By default, we display the Navigation Menu which makes the most sense for administrator (as the Simplemenu was primarily created for administrators wanting to quickly go to all administration pages.)

Theme

Select a theme to display your Simplemenu items and dropdowns. The default is called original.

The themes reside in the module sub-folder named themes. Each theme is defined in a specific directory named after the theme. That name is what appears in the dropdown in the settings.

It is possible to add new themes as

Insert Node Parameter: override (6-1.3) [special]

WARNING

This parameter is considered a security hazard. There is an option in your format definition that you have to turn on in order for the feature to work. When not selected, override is ignored. Only allow this feature in an input filter where you can trust users 100%.

One can use the override parameter to replace the expected data with their own data. Although one would think using the data directly would work as well, there are cases when this is useful.

By default the InsertNode module gets data from the $node object as defined by the system. At times, the data available in the

Filter Configuration

At this point, most of the Table of Contents configuration is done in the Table of Contents filter.

This means multiple Input formats allow you to make use of several different configurations.

  • 1. Assuming that this PlaceObject2 references a DefineSprite, this name becomes the name of this instance of the sprite. This feature enables you to place the same DefineSprite multiple times in your display list each time using a different name.

This tag will be used to specify where and how to place an object in the next frame. The PlaceObject is much different and is presented separately.

The f_depth field is used to indicate at which depth the character is inserted in the current frame. There can be only one object per depth value (thus a maximum of 65536 objects can appear on a single frame).

The f_place_has_move and f_place_has_id_ref flags are used to indicate what to do at the given depth. The following table presents what happens depending on the current value.

f_place_has_move ...

RemoveObject

Tag Info
Tag Number: 
5
Tag Type: 
Display
Tag Flash Version: 
1
Brief Description: 

Remove the specified object at the specified depth.

Tag Structure: 
struct swf_removeobject {
	swf_tag			f_tag;		/* 5 or 28 */
	if(f_tag == RemoveObject) {
		unsigned short		f_object_id_ref;
	}
	unsigned short		f_depth;
};

Remove the specified object from the display list. If the same object was placed multiple times at the specified depth1 only the last copy is removed. When only a depth is specified, the last object placed at that depth is removed from the list. Note that since version 3 it is possible to use the PlaceObject2 in order to replace an object at a given depth without having to remove it first.

  • 1. It is illegal, yet possible, to place more than one object at the same depth.

PostgreSQL and Drupal conflict

We have been running Drupal for some time now and we have noticed that it generates a very large amount of warnings in our log files.

The warning is in link with improperly formatted strings. PostgreSQL tries to follow the SQL specification to the letter and that means you cannot use the backslash character to escape special character sequences (such as \n for a newline character.)

I knew that in most cases the error was generated because of the function saving a full page or some other content in the cache. In that case, the system includes the characters: \012 and \015 (\n and \r.) That ...

Adding a Table of Contents to a view with parameters

It is possible to add a Table of Contents to a view that has to accept parameters1.

In this case, you do not want to use the solution of including the view in a node (with the Insert view filter, see Can't find doc_table_of_contents_for_views to include!) because then you lose the capability of assigning different parameters to your view (although, if the number of parameters is relatively
