After you've obtained the Wireshark sources for the first time, you
might want to keep them in sync with the sources at the Subversion
3.4.1. ... with Anonymous Subversion access
After the first time checkout is done, updating your
sources is simply done by typing (in the Wireshark source dir):
This will only take a few seconds, even on a slow internet connection. It will
replace old file versions by new ones. If you and someone else have
changed the same file since the last update, Subversion will try to merge
the changes into your private file (this works remarkably well).
3.4.2. ... from zip files
Independent of the way you retrieve the zip file of the Wireshark sources
(as described in Section 3.3, “Obtain the Wireshark sources” ), the way to
bring the changes from the official sources into your personal source tree
First of all, you will download the new zip file of the official sources
the way you did it the first time.
If you haven't changed anything in the sources, you could simply throw
away your old sources and reinstall everything just like the first time.
But be sure, that you really haven't changed anything. It might be a good
idea to simply rename the "old" dir to have it around, just in case you
remember later that you really did change something before.
Well, if you did change something in your source tree, you have to merge
the official changes
since the last update into your source tree. You will install the content
of the zip file into a new directory and use a good merge tool (e.g.
https://winmerge.sourceforge.net/ for Win32) to bring
your personal source tree in sync with the official sources again.
