/* Cygwin versioning is relatively complicated because of its status
|
|
as a shared library. Let's start with how versioning used to be done.
|
|
|
|
Historical versioning in Cygwin 16.0 to 19.5:
|
|
|
|
In the olden days of Cygwin, we had a dll major and minor version
|
|
and a registry version. The major number started at 16 because the
|
|
"b15" GNU-Win32 release of the compiler tools was out when this
|
|
scheme was started. We incremented the DLL name frequently (for
|
|
every official release) and towards the end of this period every
|
|
release used a different shared memory area to prevent DLLs from
|
|
interfering with each other (embedding a build timestamp into the
|
|
name of the shared memory area). This turned out to be a Bad Idea
|
|
(tm) because people needed to mingle separate releases and have
|
|
them work together more than we thought they would. This was
|
|
especially problematic when tty info needed to be retained when an
|
|
old Cygwin executable executed a newer one.
|
|
|
|
In the old scheme, we incremented the major number whenever a
|
|
change to the dll invalidated existing executables. This can
|
|
happen for a number of reasons, including when functions are
|
|
removed from the export list of the dll. The minor number was
|
|
incremented when a change was made that we wanted to record, but
|
|
that didn't invalidate existing executables. Both numbers were
|
|
recorded in the executable and in the dll.
|
|
|
|
In October 1998 (starting with Cygwin 19.6), we started a new method
|
|
of Cygwin versioning: */
|
|
|
|
/* The DLL major and minor numbers correspond to the "version of
|
|
the Cygwin shared library". This version is used to track important
|
|
changes to the DLL and is mainly informative in nature. */
