The alteration function is only called when the value of a parameter
changes. This removes some of the redundant logging that was caused by
calling the alteration function with the same values.
The server can now be modified with a PUT request of a modified server
resource. The server resource was reorganized to have the parameters as a
separate entity from the other more general entities of the resource.
The PUT/POST functions return a more appropriate error message when no
request body is provided.
Moved some of the constant names used in server.cc into the config.h
header.
The REST API now prints individual sessions and servers. It also lists all
servers if no specific server is given.
The functions directly call the printing functions when they should be
using the inter-thread messaging system. When the messaging system is
ready, these functions should be updated.
Closer is a template using which C-style resources can be managed
in a C++ context where exceptions can occur. By placing a C resource
in a Closer instance, it is certain the resource will be freed when
the closing scope is exited irrespective of whether that occurs due
to the normal control flow, due to a return statement or an exception
having been thrown.
To be used with Closer, the CloserTraits template must be specialized
for the type in question. With this change specializations are provided
for FILE*, json_t*, pcre_code* and pcre2_match_data*.
