This is a side-effect of one of the weirder aspects of Subversion: When you
check out a tree, it is at, say, rev 1, and all the directories and all the
files have BASE = rev 1.
Now say you check in a new file. That new file now has BASE = rev 2. But
the directory containing it is still at BASE = rev 1, because you didn't
change it. But when you do an update, the directory is updated to BASE =
rev 2.
This is rather counter-intuitive, but it's hard to see another way to do it
if you are going to version-ize directories as well as the files they
contain, and allow a tree to contain a mix of revisions.

Here's a little scenario that confuses new users: Add a new file to a
working copy directory, commit, and then do an "svn log". The log output
will *not* show the new revision just made. "Hmm", the newbie frowns, and
he does an "svn status -u", just to be absolutely sure that the working
copy is entirely up-to-date. As no discrepancies against the repository is
reported, the newbie enters a state of confusion.
BUT,
svn log -rHEAD:1
shows the new revision, whereas
svn log
does not. So apparently these two commands are not equivalent? I would have
thought that omitting a revision specification to "svn log" would imply
"-rHEAD:1".
To see the new revision with a plain "svn log" command, you have to do an
"svn update" first, even though "svn status -u" says it's not
necessary. Very confusing for a newbie. What is the reason for this
behaviour?
If there really is a compelling reason, then the book should mention it in
the "newbie" pedagogical sections, and maybe also point it out in the
reference section.
Here is a sample shell session to illustrate the confusing behaviour:
nso@SBMA:/tmp> svn --version | head -1
svn, version 1.1.1 (r11581)
nso_at_SBMA:/tmp> svn co file:///tmp/rep work
A work/mydir
Checked out revision 1.
nso@SBMA:/tmp> cd work
nso@SBMA:/tmp/work> cd mydir
nso@SBMA:/tmp/work/mydir> svn log
