Hello dE,
I can only give you my own interpretation of this document.
First of all the Mutex directive in Apache httpd 2.4.x replaces
several different directives from Apache httpd 2.2.x.
The SVN commit for this is 883540.
- http://svn.apache.org/viewvc?view=revision&revision=883540
The phrase "the first argument" in both cases probably means the
first argument after the mechanism.
The doc should be worded more clearly. (So this should probably
changed to "the second argument".)
The mechanism is what kind of mutex technology is used.
Apache httpd uses several different mutexes for different
purposes.
The mutex-name specifies which of these mutexes the Mutex
directive applies to.
It is a little confusing that either one of these arguments can
have the value "default".
So the phrase "The following mutex mechanisms are
available:" applies to the mechanism (argument 1).
And the phrase "The following table documents" applies to the
mutex-name (argument 2).
I hope this helps.
Thanks,
Mike Rumph

Hi.
I was reading this --
http://httpd.apache.org/docs/trunk/mod/core.html#mutex
Quoting what's written here --
Specify default as the
first argument to change the settings for all mutexes
As we know mutex is a mechanism; it appears Apache has settings
for each mutex it implements.
specify a mutex name (see table below)
as the first argument to override defaults only for that
mutex.
So the table starting with 'The following table documents....'
lists all the mechanisms. But before the table there exists a
list with the heading 'The following mutex mechanisms are
available:'.
So I don't understand which one of these is the mutex mechanism.
Also the statement --
specify a mutex name (see table below)
as the first argument to override defaults only for that
mutex.
Contradicts the examples --
Mutex sysvsem default
Mutex fcntl:/var/httpd/locks mpm-accept
Where the entries in the table are not the first argument,
instead the list starting with 'The following mutex mechanisms
are available:' is.
Thanks for any clarification.
Before we continue, I would like to clarify another doubt that I
have.
There's a 'mutex mechanism' and then there's a 'mutex name'. What's
the difference?
