This patch removes the component_entry_point library, which used to proved a hook for the libc to intercept the call of the 'Component::construct' function. The mechansim has several shortcomings (see the discussion in the associated issue) and was complex. So we eventually discarded the approach in favor of the explicit handling of the startup. A regular Genode component provides a 'Component::construct' function, which is determined by the dynamic linker via a symbol lookup. For the time being, the dynamic linker falls back to looking up a 'main' function if no 'Component::construct' function could be found. The libc provides an implementation of 'Component::construct', which sets up the libc's task handling and finally call the function 'Libc::Component::construct' from the context of the appllication task. This function is expected to be provided by the libc-using application. Consequently, Genode components that use the libc have to implement the 'Libc::Component::construct' function. The new 'posix' library provides an implementation of 'Libc::Component::construct' that calls a main function. Hence, POSIX programs that merely use the POSIX API merely have to add 'posix' to the 'LIBS' declaration in their 'target.mk' file. Their execution starts at 'main'. Issue #2199 |

Pingpong is a simple test where a client sends ping packets with different sizes to a server. The client has to specify the serverip in its config as well as the start and end of the ping packet sizes in bytes. ! <start name="test-ping_client"> ! <resource name="RAM" quantum="16M"/> ! <config> ! <argv verbose="1" serverip="x.x.x.x" startsize="256" endsize="32768" /> ! </config> ! </start> If verbose is set 1 the client and the server will print the id and the size of each packet (packet header + payload size).
