+# slowcgi-portable
+
+This is an **unofficial** portable version of [slowcgi(8)][slowcgi], a
+FastCGI to CGI wrapper server. It's intended to ship with as little
+changes as possible to allow it to compile and work on a variety of
+systems and otherwise follow closely the development in the OpenBSD
+src tree. All portable-specific commits have the "portable:" prefix
+in the log message.
+
+[slowcgi]: https://man.openbsd.org/slowcgi
+
+The versioning scheme follows the OpenBSD one, that's why the first
+version is 7.2.
+
+## Building
+
+The dependencies are:
+
+ - libevent
+
+and optionally pkg-config.
+
+To build, issue:
+
+ $ ./configure
+ $ make
+ # make install # eventually
+
+The build can be customized by passing arguments to the configure
+script or by using a `configure.local` file; see `./configure -h` and
+[`configure.local.example`](configure.local.example) for more
+information.
+
+For Linux users with libbsd installed, the configure script can be
+instructed to use libbsd as follows:
+
+ CFLAGS="$(pkg-config --cflags libbsd-overlay)" \
+ ./configure LDFLAGS="$(pkg-config --libs libbsd-overlay)"

+/*
+ * This file defines five types of data structures: singly-linked lists,
+ * lists, simple queues, tail queues and XOR simple queues.
+ *
+ *
+ * A singly-linked list is headed by a single forward pointer. The elements
+ * are singly linked for minimum space and pointer manipulation overhead at
+ * the expense of O(n) removal for arbitrary elements. New elements can be
+ * added to the list after an existing element or at the head of the list.
+ * Elements being removed from the head of the list should use the explicit
+ * macro for this purpose for optimum efficiency. A singly-linked list may
+ * only be traversed in the forward direction. Singly-linked lists are ideal
+ * for applications with large datasets and few or no removals or for
+ * implementing a LIFO queue.
+ *
+ * A list is headed by a single forward pointer (or an array of forward
+ * pointers for a hash table header). The elements are doubly linked
+ * so that an arbitrary element can be removed without a need to
+ * traverse the list. New elements can be added to the list before
+ * or after an existing element or at the head of the list. A list
+ * may only be traversed in the forward direction.
+ *
+ * A simple queue is headed by a pair of pointers, one to the head of the
+ * list and the other to the tail of the list. The elements are singly
+ * linked to save space, so elements can only be removed from the
+ * head of the list. New elements can be added to the list before or after
+ * an existing element, at the head of the list, or at the end of the
+ * list. A simple queue may only be traversed in the forward direction.
+ *
+ * A tail queue is headed by a pair of pointers, one to the head of the
+ * list and the other to the tail of the list. The elements are doubly
+ * linked so that an arbitrary element can be removed without a need to
+ * traverse the list. New elements can be added to the list before or
+ * after an existing element, at the head of the list, or at the end of
+ * the list. A tail queue may be traversed in either direction.
+ *
+ * An XOR simple queue is used in the same way as a regular simple queue.
+ * The difference is that the head structure also includes a "cookie" that
+ * is XOR'd with the queue pointer (first, last or next) to generate the
+ * real pointer value.
+ *
+ * For details on the use of these macros, see the queue(3) manual page.
