| * The initialization phase inside the Apache API is totally bogus. |
| * We actually have three non-trivial problems: |
| * |
| * 1. Under Unix the API does a 2-round initialization of modules while |
| * under Win32 it doesn't. This means we have to make sure that at |
| * least the pass phrase dialog doesn't occur twice. We overcome this |
| * problem by using a counter (mc->nInitCount) which has to |
| * survive the init rounds. |
| * |
| * 2. Between the first and the second round Apache detaches from |
| * the terminal under Unix. This means that our pass phrase dialog |
| * _has_ to be done in the first round and _cannot_ be done in the |
| * second round. |
| * |
| * 3. When Dynamic Shared Object (DSO) mechanism is used under Unix the |
| * module segment (code & data) gets unloaded and re-loaded between |
| * the first and the second round. This means no global data survives |
| * between first and the second init round. We overcome this by using |
| * an entry ("ssl_module") inside the ap_global_ctx. |
| * |
| * The situation as a table: |
| * |
| * Unix/static Unix/DSO Win32 Action Required |
| * (-DSHARED_MODULE) (-DWIN32) |
| * ----------- ----------------- --------- ----------------------------------- |
| * - load module - - |
| * init init init SSL library init, Pass Phrase Dialog |
| * detach detach - - |
| * - reload module - - |
| * init init - SSL library init, mod_ssl init |
