This is recommended for forward-compatibility.

Up to now, the Changelog has essentially been a (manually maintained)
copy of the git commit history. This doesn't seem to have any point
other than following the GNU coding standards. I believe it's much
better to use the Changelog to summarize the release-to-release
changes that are most important for users (as was done in the NEWS
file until now).

The GNU flavor merely requires to existence of some files (including
README, but we prefer README.md), so there seems to be little point
in using it.

|
|
Remaining README file is just to make automake happy.

sshfs-fuse always returned 0 in access(file, X_OK) calls, causing nautilus
to prompt "Do you want to run "login.defs", or display its contents?" for
text files that were not executable.

Accessing directories with many (several thousand) files over sshfs is
slow, because most SFTP server implementations only send a fixed amount
of entries per READDIR command (e.g. OpenSSH SFTP: 100 entries). This
patch implements sending several READDIR commands in parallel, in order
to speed up directory listing in these cases.
An option (sync_readdir) is also added so that users can easily switch
on the old behaviour.
The performance improvement is astonishing. Accessing a directory with
30k files in from a remote server that has a RTT of 15ms via OpenSSH
SFTP:
Synchronous readdir:
$ ./sshfs -o sync_readdir host:/tmp /mnt/temp
$ time "ls" -1 /mnt/temp/test | wc -l
30000
"ls" -1 /mnt/temp/test 0.07s user 0.01s system 1% cpu 6.928 total
Asynchronous readdir:
$ ./sshfs host:/tmp /mnt/temp
$ time "ls" -1 /mnt/temp/test | wc -l
30000
"ls" -1 /mnt/temp/test 0.07s user 0.01s system 12% cpu 0.605 total
Accessing a directory with 100k files shows even more dramatic
improvement:
Synchronous readdir:
$ ./sshfs -o sync_readdir host:/tmp /mnt/temp
$ time "ls" -1 /mnt/temp/test2 | wc -l
100000
"ls" -1 /mnt/temp/test2 0.67s user 1.22s system 0% cpu 3:31.56 total
Asynchronous readdir:
$ ./sshfs host:/tmp /mnt/temp
$ time "ls" -1 /mnt/temp/test2 | wc -l
100000
"ls" -1 /mnt/temp/test2 0.20s user 0.03s system 14% cpu 1.631 total
This can easily be reproduced by creating a directory on a server and
touching a lot of files in it:
$ mkdir /tmp/test
$ cd /tmp/test
$ for i in $(seq 1 30000); do touch $i; done

In the past we relied on libosxfuse including a working unnamed semaphore
implmentation for Mac OS X. This will not be the case in future releases of
OSXFUSE, therefore we need to add our own implementation.

This prevents I/O error being returned after a successful mount if a symlink is
mounted.

The only difference between version 2.4.0 and 2.4.1 is the updated man page to
reflect Darwin/OS X specific changes to upstream SSHFS.

* Volumes are unmounted using "umount" not "fusermount"
* idmap=user is the deafault setting on Darwin/OS X

Add -o slave. This option routes the sftp communication over stdin and stdout,
