<P>The latest version of the VFS for phpGroupWare combines actual file system

manipulation with fully integrated database support. It features nearly transparent

handling of files and directories, as well as files inside and outside the

virtual root. This document is intended to provide API and application developers

with a guide to incorporating the VFS into their work.</P>

<P>The VFS in located in phpgwapi/inc/class.vfs.inc.php. You can look over

it, but I don't suggest trying to understand how it works. It isn't necessary
|

to know its internals to use it, but you may find the inline comments helpful.
|

The basic things to keep in mind:</P>
|

<P>
|

<UL>
|

<LI>Files and directories are synonymous in almost all cases</LI>
|

</UL>

<PRE>

$phpgw->vfs->mv ("file1", "dir/file2");
|

$phpgw->vfs->mv ("dir1", "dir/dir1");
|
||||
$phpgw->vfs->rm ("file");
|
||||
$phpgw->vfs->rm ("dir");
|
||||
</PRE>
|
||||
</P>
|
||||
<P>All work as you would except them to. The major exception is:</P>
|
||||
<P>
|
||||
<PRE>
|
||||
$phpgw->vfs->touch ("file");
|
||||
</PRE>
|

</P>
|

<P>vs.</P>
|

<P>

<UL>
|
||||
<LI>Users and groups and synonymous</LI>
|
||||
</UL>
|
||||
</P>
|
||||
<P>As far as the actual paths are concerned, users and groups are the same.
|
||||
The VFS has no built in ACL support, so /home/username works the same as /home/groupname.
|
||||
See the note on AC L support in the Notes section.</P>
|

<P>
|
||||
<UL>
|
||||
<LI>You should never have to know the real path of files</LI>
|
||||
</UL>
|
||||
</P>
|
||||
<P>One of the VFS's responsibilities is to translate paths for you. While
|
||||
you certainly <EM>can</EM> operate using full paths, it is much simpler to use the virtual
|
||||
paths. For example, instead of using:</P>
|
||||
<P>
|
||||
<PRE>
|
||||
$phpgw->vfs->cp ("/var/www/phpgroupware/files/home/user/file1", "/var/www/phpgroupware/files/home/user/file2", array (RELATIVE_NONE|VFS_REAL, RELATIVE_NONE|VFS_REAL));
|
||||
</PRE>
|
||||
</P>
|
||||
<P>you might use</P>
|
||||
<P>
|
||||
<PRE>
|
||||
$phpgw->vfs->cp ("/home/user/file1", "/home/user/file2", array (RELATIVE_NONE, RELATIVE_NONE));
|
||||
</PRE>
|
||||
</P>
|
||||
<P>(We'll get to the RELATIVE's in a minute.)</P>
|
||||
<P>Site administrators should be able to move their files dir around on their
|
||||
system and know that everything will continue to work smoothly.</P>
|
||||
<P>
|
||||
<UL>
|
||||
<LI>Relativity is <EM>vital</EM></LI>
|
||||
</UL>
|
||||
</P>
|
||||
<P>Relativity is a new feature in the VFS, and its importance cannot be stressed
|
||||
enough. It will make your life much easier, especially for file system intensive
|
||||
applications, but it will take some getting used to. If something doesn't work
|
||||
right the first time, chances are great it has to do with incorrect relativity
|
||||
settings. We will deal with relativity in depth in the Relativity section.</P>

<P>These are two functions you'll need to know before we get into relativity.</P>
|

<H2><A NAME="sec:path_parts"></A> <A NAME="ss3.1">3.1</A> <A HREF="vfs.html#toc3.1">path_parts ()</A>
|
||||
</H2>
|
||||
|
||||
<P>The job of path_parts () is to translate any given file location into its
|
||||
many component parts for any relativity. The prototype for path_parts () is:</P>
|
||||
<P>
|
||||
<PRE>
|
||||
function path_parts ($string, $relatives = array (RELATIVE_CURRENT), $object = True)
|
||||
</PRE>
|
||||
</P>
|
||||
<P>$string is the path you want to translate, $relatives is
|
||||
the standard relativity array, and $object specifies how you would like
|
||||
the return value: if $object is True, an object will be returned; if
|
||||
$object is False, an array will be returned. I think you'll find the
|
||||
object easier to deal with, and we'll be using it throughout this document.
|
||||
The most important returned values (but not all) for path_parts () are:</P>
|
||||
<P>
|
||||
<PRE>
|
||||
fake_full_path
|
||||
fake_leading_dirs
|
||||
fake_extra_path
|
||||
fake_name
|
||||
real_full_path
|
||||
real_leading_dirs
|
||||
real_extra_path
|
||||
real_name
|
||||
</PRE>
|
||||
</P>
|
||||
<P>Just like you would think, fake_full_path contains the full virtual path
|
||||
of $string, and real_full_path contains the full real path of $string.
|
||||
The fake_name and real_name variables should always be the same, and contain
|
||||
the final file or directory name. The leading_dirs contain everything except
|
||||
the name, and the extra_path is everything from the / before "home" to the end
|
||||
of the leading_dirs. To better illustrate, here is an example:</P>
|
||||
<P>
|
||||
<PRE>
|
||||
$p = $phpgw->vfs->path_parts ("/home/jason/dir/file", array (RELATIVE_NONE));
|
||||
</PRE>
|
||||
</P>
|
||||
<P>
|
||||
<UL>
|
||||
<LI>$p->fake_full_path - /home/jason/dir/file</LI>
|
||||
<LI>$p->fake_leading_dirs - /home/jason/dir</LI>
|
||||
<LI>$p->fake_extra_path - home/jason/dir</LI>
|
||||
<LI>$p->fake_name - file</LI>
|
||||
<LI>$p->real_full_path - /var/www/phpgroupware/files/home/jason/dir/file</LI>
|
||||
<LI>$p->real_leading_dirs - /var/www/phpgroupware/files/home/jason/dir
|
||||
</LI>
|
||||
<LI>$p->real_extra_path - home/jason/dir</LI>
|
||||
<LI>$p->real_name - file</LI>
|
||||
</UL>
|
||||
</P>
|
||||
<P>As you can see, path_parts () is a very useful function and will save you
|
||||
from doing those darn substr ()'s yourself. For those of you used to the prior
|
||||
VFS, note that <EM>getabsolutepath () is depreciated</EM>. getabsolutepath () still
|
||||
exists (albeit in a much different form), and is responsible for some of the
|
||||
path translation, but it is an <EM>internal</EM> function only. Applications should
|
||||
only use path_parts (). We have shown you how to use path_parts () so you can
|
||||
experiment with it using different paths and relativities as we relativity
|
||||
in Section
|
||||
<A HREF="vfs-4.html#sec:relativity"></A>.</P>
|
||||
<H2><A NAME="sec:cd"></A> <A NAME="ss3.2">3.2</A> <A HREF="vfs.html#toc3.2">cd ()</A>
|
||||
</H2>
|
||||
|
||||
<P>Ok, one more thing before we discuss relativity, and that is the cd ()
|
||||
function. Part of the overall goal for the VFS in phpGroupWare is to give the
|
||||
user a seamless experience during their session. For example, if they upload
|
||||
a file using a file manager to /home/my_group/project1, and then go to download
|
||||
an email attachment, the default directory will be /home/my_group/project1.
|
||||
This is accomplished using the cd () function. The prototype and examples:</P>
|
||||
|
||||
<P>
|
||||
<PRE>
|
||||
function cd ($target = "/", $relative = True, $relatives = array (RELATIVE_CURRENT))
|
||||
$phpgw->vfs->cd ("/"); /* cd to their home directory */
|
||||
$phpgw->vfs->cd ("/home/jason/dir", False, array (RELATIVE_NONE)); /* cd to /home/jason/dir */
|
||||
$phpgw->vfs->cd ("dir2", True); /* When following the above, cd's to /home/jason/dir/dir2 */
|
||||
</PRE>
|
||||
</P>
|
||||
<P>If $relatives is True, the $target is simply appended to
|
||||
the current path. If you want to know what the current path is, use $phpgw->vfs->pwd
|
||||
().</P>
|
||||
<P>Now you're ready for relativity.</P>

|

|
||||
<P>Ok, just one last thing before we get into relativity. You will notice
|
||||
throughout the examples the use of $fakebase. $fakebase is by
|
||||
default "/home". The old VFS was hard-coded to use "/home", but the naming choice
|
||||
for this is now up to administrators. See the "Notes -> Fakebase directory"
|
||||
section for more information. Throughout the rest of this document, you will
|
||||
see $fakebase used in calls to the VFS, and /home used in actual paths.

<EM>You should always use $fakebase when making applications. </EM>I suggest
|
||||
doing $fakebase = $phpgw->vfs->fakebase; right off the
|
||||
bat to keep things neater.</P>
|
||||
<H2><A NAME="ss4.1">4.1</A> <A HREF="vfs.html#toc4.1">What is it and how does it work?</A>
|
||||
</H2>
|
||||
|
||||
<P>One of the design challenges for a Virtual File System is to try to figure
|
||||
out whether the calling application is referring to a file inside or outside
|
||||
the virtual root, and if inside, exactly where. To solve this problem, the
|
||||
phpGroupWare VFS uses RELATIVE defines that are used in bitmasks passed to
|
||||
each function. The result is that any set of different relativities can be
|
||||
used in combination with each other. Let's look at a few examples. Say you
|
||||
want to move "logo.png" from the user's home directory to the current directory.</P>
|
||||
|
||||
<P>
|
||||
<PRE>
|
||||
$phpgw->vfs->mv ("logo.png", "", array (RELATIVE_USER, RELATIVE_ALL));
|
||||
</PRE>
|
||||
</P>
|
||||
<P>RELATIVE_USER means relative to the user's home directory. RELATIVE_ALL
|
||||
means relative to the current directory, as set by cd () and as reported by
|
||||
pwd (). So if the current directory was "$fakebase/my_group/project1",
|
||||
the call to mv () would be processed as:</P>
|
||||
<P>
|
||||
<PRE>
|
||||
MOVE "$fakebase/jason/logo.png" TO "$fakebase/my_group/project1/logo.png"
|
||||
</PRE>
|
||||
</P>
|
||||
<P>and the actual file system call would be:</P>
|
||||
<P>
|
||||
<PRE>
|
||||
rename ("/var/www/phpgroupware/files/home/jason/logo.php", "/var/www/phpgroupware/files/home/my_group/project1/logo.png");
|
||||
</PRE>
|
||||
</P>
|
||||
<P>Those used to the old VFS will note that you do not have to translate the
|
||||
path beforehand. Let's look at another example. Suppose you were moving an
|
||||
email attachment stored in phpGroupWare's temporary directory to the "attachments"
|
||||
directory within the user's home directory (we're assuming the attachments
|
||||
directory exists). Note that the temporary directory is <EM>outside</EM> the virtual
|
||||
root.</P>
|
||||
<P>
|
||||
<PRE>
|
||||
$phpgw->vfs->mv ("$phpgw_info[server][temp_dir]/$randomdir/$randomfile", "attachments/actual_name.ext", array (RELATIVE_NONE|VFS_REAL, RELATIVE_USER));
|
||||
</PRE>
|
||||
</P>
|
||||
<P>$randomdir and $randomfile are what the directory and file
|
||||
might be called before they are given a proper name by the user, which is actual_name.ext
|
||||
in this example. RELATIVE_NONE is the define for using full path names. However,
|
||||
RELATIVE_NONE is still relative to the virtual root, so we pass along VFS_REAL
|
||||
as well, to say that the file is <EM>outside</EM> the virtual root, somewhere else in
|
||||
the file system. Once again, RELATIVE_USER means relative to the user's home
|
||||
directory. So the actual file system call might look like this (keep in mind
|
||||
that $randomdir and $randomfile are just random strings):</P>
|
||||
<P>
|
||||
<PRE>
|
||||
rename ("/var/www/phpgroupware/tmp/0ak5adftgh7/jX42sC9M", "/var/www/phpgroupware/files/home/users/jason/attachments/actual_name.ext");
|
||||
</PRE>
|
||||
</P>
|
||||
<P>Of course you don't have to know that, nor should you be concerned with
|
||||
it; you can take it for granted that the VFS will translate the paths correctly.
|
||||
Let's take a look at one more example, this time using the RELATIVE_USER_APP
|
||||
define. RELATIVE_USER_APP is used to store quasi-hidden application files,
|
||||
similar to the Unix convention of ~/.appname. It simply appends .appname
|
||||
to the user's home directory. For example, if you were making an HTML editor
|
||||
application named htmledit, and wanted to keep a backup file in case something
|
||||
goes wrong, you would use RELATIVE_USER_APP to store it:</P>
|
||||
<P>
|
||||
<PRE>
|
||||
$phpgw->vfs->write ("file.name~", array (RELATIVE_USER_APP), $contents);
|
||||
</PRE>
|
||||
</P>
|
||||
<P>This assumes that ~/.htmledit exists of course. The backup file "file.name~"
|
||||
would then be written in $fakebase/jason/.htmledit/file.name~.
|
||||
Note that storing files like this might not be as good of a solution as storing
|
||||
them in the temporary directory or in the database. But it is there in case
|
||||
you need it.</P>

<H2><A NAME="sec:relatives_defaults"></A> <A NAME="ss4.3">4.3</A> <A HREF="vfs.html#toc4.3">Defaults</A>
|
||||
</H2>
|
||||
|
||||
<P>You might be thinking to yourself that passing along RELATIVE defines with
|
||||
every VFS call is overkill, especially if your application always uses the
|
||||
same relativity. The default RELATIVE define for all VFS calls is RELATIVE_CURRENT.
|
||||
RELATIVE_CURRENT itself defaults to RELATIVE_ALL (relative to the current path),
|
||||
<EM>unless</EM> your application sets a specific relativity. If your application requires
|
||||
most of the work to be done outside of the virtual root, you may wish to set
|
||||
RELATIVE_CURRENT to RELATIVE_NONE|VFS_REAL. set_relative () is the function
|
||||
to do this. For example:</P>
|
||||
<P>
|
||||
<PRE>
|
||||
$phpgw->vfs->set_relative (RELATIVE_NONE|VFS_REAL);
|
||||
$phpgw->vfs->read ("/etc/passwd");
|
||||
$phpgw->vfs->cp ("/usr/include/stdio.h", "/tmp/stdio.h");
|
||||
$phpgw->vfs->cp ("/usr/share/pixmaps/yes.xpm", "icons/yes.xpm", array (RELATIVE_CURRENT, RELATIVE_USER));
|
||||
</PRE>
|
||||
</P>
|
||||
<P>You should notice that no relativity array is needed in the other calls
|
||||
that refer to files outside the virtual root, but one is needed for calls that
|
||||
include files inside the virtual root. Any RELATIVE define can be set as the
|
||||
default and works in the same fashion. To retrieve the currently set define,
|
||||
use get_relative (). Note that the relativity is reset after each page request;
|
||||
that is, it's good only for the life of the current page loading, and is not
|
||||
stored in session management.</P>

</H2>
|

|

<P>Data about the files and directories within the virtual root is kept in

the SQL database. Currently, this information includes:</P>
|
||||
<P>
|
||||
<UL>
|

<LI>File ID (used internally, primary key for table)</LI>
|

<LI>Owner ID (phpGW account_id)</LI>

<P>The internal names of these (the database column names) are stored in the

|

|
||||
|

<P>Note that no information is kept about files outside the virtual root.
|

If a file is moved outside, all records of it are delete from the database.
|
||||
If a file is moved into the virtual root, some information, specifically MIME-type,
|
||||
is not stored in the database. The vital information has defaults: owner is
|
||||
based on where the file is being stored; size is correctly read; deleteable
|

is set to Y.</P>

<H2><A NAME="sec:acl_support"></A> <A NAME="ss6.2">6.2</A> <A HREF="vfs.html#toc6.2">ACL support</A>
|
||||
</H2>
|
||||
|
||||
<P>Because of the many different ways the VFS can be used, complete ACL support
|
||||
is not built in. There is a bit of access control built in, just because of
|
||||
the way database queries are made. However, that is a discussion beyond the
|
||||
scope of this document. Full ACL support may be added at a later time. For
|
||||
now, it is fairly easy to add basic access control to your application by matching
|
||||
path expressions. The VFS always follows the same naming convention of $fakebase/userorgroup.
|
||||
So if you need to check if a user has access to $fakebase/whatever/dir/file,
|
||||
you need only know if they their username is 'whatever' or if they belong to
|
||||
the group 'whatever', and that the group has access to your application. Here
|
||||
is an example from PHPWebHosting:</P>

||||

###
|

# We determine if they're in their home directory or a group's directory
|
||||
# If they request a group's directory, we ensure they have access to the group,
|
||||
# and the group has access to the app
|
||||

|
||||
</H2>
|
||||
|
||||
<P>The old VFS was hard-coded to use "/home" as the fake base directory,
|
||||
even though the user never saw it. With the new system, crafty administrators
|
||||
may wish to change "/home" to something else, say "/users"
|
||||
or "/public_html". The fake base directory name is stored in $phpgw->vfs->fakebase,
|
||||
and changing it will transparently change it throughout the VFS and all applications.
|
||||
However, this must be done <EM>before</EM> any data is in the VFS database. If you wish
|
||||
to change it afterwords, you'll have to manually update the database, replacing
|
||||
the old value with the new value. <EM>Application programmers need to recognize
|
||||
that /home is not absolute, and use $phpgw->vfs->fakebase instead</EM>.
|
||||
I suggest setting $fakebase = $phpgw->vfs->fakebase; right
|
||||
off the bat to keep things neater.</P>

Abstract
|
||||
|
||||
The VFS, or Virtual File System, handles all file system activity for
|
||||
phpGroupWare.
|
||||
|
||||
1 Introduction and Purpose<sec:introduction>
|
||||
|
||||
The latest version of the VFS for phpGroupWare combines actual file
|
||||
system manipulation with fully integrated database support. It features
|
||||
nearly transparent handling of files and directories, as well as files
|
||||
inside and outside the virtual root. This document is intended to
|
||||
provide API and application developers with a guide to incorporating
|
||||
the VFS into their work.
|
||||
|
||||
2 Basics<sec:basics>
|
||||
|
||||
2.1 Prerequisites<sec:prerequisites>
|
||||
|
||||
You must explicitly enable the VFS class. To do this, set "enable_vfs_class"
|
||||
to True in $phpgw_info["flags"]. An example:
|
||||
|
||||
$phpgw_info["flags"] = array("currentapp" => "phpwebhosting",
|
||||
|
||||
"noheader" => False,
|
||||
|
||||
"noappheader" => False,
|
||||
|
||||
"enable_vfs_class" => True,
|
||||
|
||||
"enable_browser_class" => True);
|
||||
|
||||
2.2 Concepts<sec:concepts>
|
||||
|
||||
The VFS in located in phpgwapi/inc/class.vfs.inc.php. You can look
|
||||
over it, but I don't suggest trying to understand how it works. It
|
||||
isn't necessary to know its internals to use it, but you may find
|
||||
the inline comments helpful. The basic things to keep in mind:
|
||||
|
||||
* Files and directories are synonymous in almost all cases
|
||||
|
||||
$phpgw->vfs->mv ("file1", "dir/file2");
|
||||
|
||||
$phpgw->vfs->mv ("dir1", "dir/dir1");
|
||||
|
||||
$phpgw->vfs->rm ("file");
|
||||
|
||||
$phpgw->vfs->rm ("dir");
|
||||
|
||||
All work as you would except them to. The major exception is:
|
||||
|
||||
$phpgw->vfs->touch ("file");
|
||||
|
||||
vs.
|
||||
|
||||
$phpgw->vfs->mkdir ("dir");
|
||||
|
||||
* Users and groups and synonymous
|
||||
|
||||
As far as the actual paths are concerned, users and groups are the
|
||||
same. The VFS has no built in ACL support, so /home/username works
|
||||
the same as /home/groupname. See the note on AC L support in the Notes
|
||||
section.
|
||||
|
||||
* You should never have to know the real path of files
|
||||
|
||||
One of the VFS's responsibilities is to translate paths for you. While
|
||||
you certainly can operate using full paths, it is much simpler to
|
||||
use the virtual paths. For example, instead of using:
|
||||
|
||||
$phpgw->vfs->cp ("/var/www/phpgroupware/files/home/user/file1", "/var/www/phpgroupware/files/home/user/file2",
|
||||
array (RELATIVE_NONE|VFS_REAL, RELATIVE_NONE|VFS_REAL));
|
||||
|
||||
you might use
|
||||
|
||||
$phpgw->vfs->cp ("/home/user/file1", "/home/user/file2", array (RELATIVE_NONE,
|
||||
RELATIVE_NONE));
|
||||
|
||||
(We'll get to the RELATIVE's in a minute.)
|
||||
|
||||
Site administrators should be able to move their files dir around on
|
||||
their system and know that everything will continue to work smoothly.
|
||||
|
||||
* Relativity is vital
|
||||
|
||||
Relativity is a new feature in the VFS, and its importance cannot be
|
||||
stressed enough. It will make your life much easier, especially for
|
||||
file system intensive applications, but it will take some getting
|
||||
used to. If something doesn't work right the first time, chances are
|
||||
great it has to do with incorrect relativity settings. We will deal
|
||||
with relativity in depth in the Relativity section.
|
||||
|
||||
3 Basic Functions<sec:basic_functions>
|
||||
|
||||
These are two functions you'll need to know before we get into relativity.
|
||||
|
||||
3.1 path_parts ()<sec:path_parts>
|
||||
|
||||
The job of path_parts () is to translate any given file location into
|
||||
its many component parts for any relativity. The prototype for path_parts
|
||||
() is:
|
||||
|
||||
function path_parts ($string, $relatives = array (RELATIVE_CURRENT),
|
||||
$object = True)
|
||||
|
||||
$string is the path you want to translate, $relatives is the standard
|
||||
relativity array, and $object specifies how you would like the return
|
||||
value: if $object is True, an object will be returned; if $object
|
||||
is False, an array will be returned. I think you'll find the object
|
||||
easier to deal with, and we'll be using it throughout this document.
|
||||
The most important returned values (but not all) for path_parts ()
|
||||
are:
|
||||
|
||||
fake_full_path
|
||||
|
||||
fake_leading_dirs
|
||||
|
||||
fake_extra_path
|
||||
|
||||
fake_name
|
||||
|
||||
real_full_path
|
||||
|
||||
real_leading_dirs
|
||||
|
||||
real_extra_path
|
||||
|
||||
real_name
|
||||
|
||||
Just like you would think, fake_full_path contains the full virtual
|
||||
path of $string, and real_full_path contains the full real path of
|
||||
$string. The fake_name and real_name variables should always be the
|
||||
same, and contain the final file or directory name. The leading_dirs
|
||||
contain everything except the name, and the extra_path is everything
|
||||
from the / before "home" to the end of the leading_dirs. To better
|
||||
illustrate, here is an example:
|
||||
|
||||
$p = $phpgw->vfs->path_parts ("/home/jason/dir/file", array (RELATIVE_NONE));
|
||||
|
||||
* $p->fake_full_path - /home/jason/dir/file
|
||||
|
||||
* $p->fake_leading_dirs - /home/jason/dir
|
||||
|
||||
* $p->fake_extra_path - home/jason/dir
|
||||
|
||||
* $p->fake_name - file
|
||||
|
||||
* $p->real_full_path - /var/www/phpgroupware/files/home/jason/dir/file
|
||||
|
||||
* $p->real_leading_dirs - /var/www/phpgroupware/files/home/jason/dir
|
||||
|
||||
* $p->real_extra_path - home/jason/dir
|
||||
|
||||
* $p->real_name - file
|
||||
|
||||
As you can see, path_parts () is a very useful function and will save
|
||||
you from doing those darn substr ()'s yourself. For those of you used
|
||||
to the prior VFS, note that getabsolutepath () is depreciated. getabsolutepath
|
||||
() still exists (albeit in a much different form), and is responsible
|
||||
for some of the path translation, but it is an internal function only.
|
||||
Applications should only use path_parts (). We have shown you how
|
||||
to use path_parts () so you can experiment with it using different
|
||||
paths and relativities as we relativity in Section [sec:relativity].
|
||||
|
||||
3.2 cd ()<sec:cd>
|
||||
|
||||
Ok, one more thing before we discuss relativity, and that is the cd
|
||||
() function. Part of the overall goal for the VFS in phpGroupWare
|
||||
is to give the user a seamless experience during their session. For
|
||||
example, if they upload a file using a file manager to /home/my_group/project1,
|
||||
and then go to download an email attachment, the default directory
|
||||
will be /home/my_group/project1. This is accomplished using the cd
|
||||
() function. The prototype and examples:
|
||||
|
||||
function cd ($target = "/", $relative = True, $relatives = array (RELATIVE_CURRENT))
|
||||
|
||||
$phpgw->vfs->cd ("/"); /* cd to their home directory */
|
||||
|
||||
$phpgw->vfs->cd ("/home/jason/dir", False, array (RELATIVE_NONE));
|
||||
/* cd to /home/jason/dir */
|
||||
|
||||
$phpgw->vfs->cd ("dir2", True); /* When following the above, cd's to
|
||||
/home/jason/dir/dir2 */
|
||||
|
||||
If $relatives is True, the $target is simply appended to the current
|
||||
path. If you want to know what the current path is, use $phpgw->vfs->pwd
|
||||
().
|
||||
|
||||
Now you're ready for relativity.
|
||||
|
||||
4 Relativity<sec:relativity>
|
||||
|
||||
Ok, just one last thing before we get into relativity. You will notice
|
||||
throughout the examples the use of $fakebase. $fakebase is by default
|
||||
"/home". The old VFS was hard-coded to use "/home", but the naming
|
||||
choice for this is now up to administrators. See the "Notes -> Fakebase
|
||||
directory" section for more information. Throughout the rest of this
|
||||
document, you will see $fakebase used in calls to the VFS, and /home
|
||||
used in actual paths. You should always use $fakebase when making
|
||||
applications. I suggest doing $fakebase = $phpgw->vfs->fakebase; right
|
||||
off the bat to keep things neater.
|
||||
|
||||
4.1 What is it and how does it work?
|
||||
|
||||
One of the design challenges for a Virtual File System is to try to
|
||||
figure out whether the calling application is referring to a file
|
||||
inside or outside the virtual root, and if inside, exactly where.
|
||||
To solve this problem, the phpGroupWare VFS uses RELATIVE defines
|
||||
that are used in bitmasks passed to each function. The result is that
|
||||
any set of different relativities can be used in combination with
|
||||
each other. Let's look at a few examples. Say you want to move "logo.png"
|
||||
from the user's home directory to the current directory.
|
||||
|
||||
$phpgw->vfs->mv ("logo.png", "", array (RELATIVE_USER, RELATIVE_ALL));
|
||||
|
||||
RELATIVE_USER means relative to the user's home directory. RELATIVE_ALL
|
||||
means relative to the current directory, as set by cd () and as reported
|
||||
by pwd (). So if the current directory was "$fakebase/my_group/project1",
|
||||
the call to mv () would be processed as:
|
||||
|
||||
MOVE "$fakebase/jason/logo.png" TO "$fakebase/my_group/project1/logo.png"
|
||||
|
||||
and the actual file system call would be:
|
||||
|
||||
rename ("/var/www/phpgroupware/files/home/jason/logo.php", "/var/www/phpgroupware/files/home/my_group/project1/logo.png");
|
||||
|
||||
Those used to the old VFS will note that you do not have to translate
|
||||
the path beforehand. Let's look at another example. Suppose you were
|
||||
moving an email attachment stored in phpGroupWare's temporary directory
|
||||
to the "attachments" directory within the user's home directory (we're
|
||||
assuming the attachments directory exists). Note that the temporary
|
||||
directory is outside the virtual root.
|
||||
|
||||
$phpgw->vfs->mv ("$phpgw_info[server][temp_dir]/$randomdir/$randomfile",
|
||||
"attachments/actual_name.ext", array (RELATIVE_NONE|VFS_REAL, RELATIVE_USER));
|
||||
|
||||
$randomdir and $randomfile are what the directory and file might be
|
||||
called before they are given a proper name by the user, which is actual_name.ext
|
||||
in this example. RELATIVE_NONE is the define for using full path names.
|
||||
However, RELATIVE_NONE is still relative to the virtual root, so we
|
||||
pass along VFS_REAL as well, to say that the file is outside the virtual
|
||||
root, somewhere else in the file system. Once again, RELATIVE_USER
|
||||
means relative to the user's home directory. So the actual file system
|
||||
call might look like this (keep in mind that $randomdir and $randomfile
|
||||
are just random strings):
|
||||
|
||||
rename ("/var/www/phpgroupware/tmp/0ak5adftgh7/jX42sC9M", "/var/www/phpgroupware/files/home/users/jason/attachments/actual_name.ext");
|
||||
|
||||
Of course you don't have to know that, nor should you be concerned
|
||||
with it; you can take it for granted that the VFS will translate the
|
||||
paths correctly. Let's take a look at one more example, this time
|
||||
using the RELATIVE_USER_APP define. RELATIVE_USER_APP is used to store
|
||||
quasi-hidden application files, similar to the Unix convention of
|
||||
~/.appname. It simply appends .appname to the user's home directory.
|
||||
For example, if you were making an HTML editor application named htmledit,
|
||||
and wanted to keep a backup file in case something goes wrong, you
|
||||
would use RELATIVE_USER_APP to store it:
|
||||
|
||||
$phpgw->vfs->write ("file.name~", array (RELATIVE_USER_APP), $contents);
|
||||
|
||||
This assumes that ~/.htmledit exists of course. The backup file "file.name~"
|
||||
would then be written in $fakebase/jason/.htmledit/file.name~. Note
|
||||
that storing files like this might not be as good of a solution as
|
||||
storing them in the temporary directory or in the database. But it
|
||||
is there in case you need it.
|
||||
|
||||
4.2 Complete List<sec:relatives_complete_list>
|
||||
|
||||
Here is the complete list of RELATIVE defines, and what they do:
|
||||
|
||||
RELATIVE_ROOT Don't translate the path at all. Just prepends a /.
|
||||
You'll probably want to use RELATIVE_NONE though, which handles
|
||||
both virtual and real files.
|
||||
|
||||
RELATIVE_USER User's home directory
|
||||
|
||||
RELATIVE_CURR_USER Current user's home directory. If the current
|
||||
directory is $fakebase/my_group/project1, this will return is $fakebase/my_group
|
||||
|
||||
RELATIVE_USER_APP Append .appname to the user's home directory, where
|
||||
appname is the current application's appname
|
||||
|
||||
RELATIVE_PATH DO NOT USE. Relative to the current directory, used
|
||||
in RELATIVE_ALL
|
||||
|
||||
RELATIVE_NONE Not relative to anything. Use this with VFS_REAL for
|
||||
files outside the virtual root. Note that using RELATIVE_NONE by
|
||||
itself still means relative to the virtual root
|
||||
|
||||
RELATIVE_CURRENT An alias for the currently set RELATIVE define,
|
||||
or RELATIVE_ALL if none is set (see the Defaults section)
|
||||
|
||||
VFS_REAL File is outside of the virtual root. Usually used with RELATIVE_NONE
|
||||
|
||||
RELATIVE_ALL Relative to the current directory. Use RELATIVE_ALL
|
||||
instead of RELATIVE_PATH
|
||||
|
||||
4.3 Defaults<sec:relatives_defaults>
|
||||
|
||||
You might be thinking to yourself that passing along RELATIVE defines
|
||||
with every VFS call is overkill, especially if your application always
|
||||
uses the same relativity. The default RELATIVE define for all VFS
|
||||
calls is RELATIVE_CURRENT. RELATIVE_CURRENT itself defaults to RELATIVE_ALL
|
||||
(relative to the current path), unless your application sets a specific
|
||||
relativity. If your application requires most of the work to be done
|
||||
outside of the virtual root, you may wish to set RELATIVE_CURRENT
|
||||
to RELATIVE_NONE|VFS_REAL. set_relative () is the function to do this.
|
||||
For example:
|
||||
|
||||
$phpgw->vfs->set_relative (RELATIVE_NONE|VFS_REAL);
|
||||
|
||||
$phpgw->vfs->read ("/etc/passwd");
|
||||
|
||||
$phpgw->vfs->cp ("/usr/include/stdio.h", "/tmp/stdio.h");
|
||||
|
||||
$phpgw->vfs->cp ("/usr/share/pixmaps/yes.xpm", "icons/yes.xpm", array
|
||||
(RELATIVE_CURRENT, RELATIVE_USER));
|
||||
|
||||
You should notice that no relativity array is needed in the other calls
|
||||
that refer to files outside the virtual root, but one is needed for
|
||||
calls that include files inside the virtual root. Any RELATIVE define
|
||||
can be set as the default and works in the same fashion. To retrieve
|
||||
the currently set define, use get_relative (). Note that the relativity
|
||||
is reset after each page request; that is, it's good only for the
|
||||
life of the current page loading, and is not stored in session management.

is created as a separate DocBook document (using the inline2lyx.pl

6 Notes<sec:notes>
|
||||
|
||||
6.1 Database<sec:database>
|
||||
|
||||
Data about the files and directories within the virtual root is kept
|
||||
in the SQL database. Currently, this information includes:
|
||||
|
||||
* File ID (used internally, primary key for table)
|
||||
|
||||
* Owner ID (phpGW account_id)
|
||||
|
||||
* Created by ID (phpGW account_id)
|
||||
|
||||
* Modified by ID (phpGW account_id)
|
||||
|
||||
* Created (date)
|
||||
|
||||
* Modified (date)
|
||||
|
||||
* Size (bytes)
|
||||
|
||||
* MIME type
|
||||
|
||||
* Deleteable (Y/N/Other?)
|
||||
|
||||
* Comment
|
||||
|
||||
* App (appname of application that created the file)
|
||||
|
||||
* Directory (directory the file or directory is in)
|
||||
|
||||
* Name (name of file or directory)
|
||||
|
||||
The internal names of these (the database column names) are stored
|
||||
in the $phpgw->vfs->attributes array, which is useful for loops, and
|
||||
is guaranteed to be up-to-date.
|
||||
|
||||
Note that no information is kept about files outside the virtual root.
|
||||
If a file is moved outside, all records of it are delete from the
|
||||
database. If a file is moved into the virtual root, some information,
|
||||
specifically MIME-type, is not stored in the database. The vital information
|
||||
has defaults: owner is based on where the file is being stored; size
|
||||
is correctly read; deleteable is set to Y.
|
||||
|
||||
6.2 ACL support<sec:acl_support>
|
||||
|
||||
Because of the many different ways the VFS can be used, complete ACL
|
||||
support is not built in. There is a bit of access control built in,
|
||||
just because of the way database queries are made. However, that is
|
||||
a discussion beyond the scope of this document. Full ACL support may
|
||||
be added at a later time. For now, it is fairly easy to add basic
|
||||
access control to your application by matching path expressions. The
|
||||
VFS always follows the same naming convention of $fakebase/userorgroup.
|
||||
So if you need to check if a user has access to $fakebase/whatever/dir/file,
|
||||
you need only know if they their username is 'whatever' or if they
|
||||
belong to the group 'whatever', and that the group has access to your
|
||||
application. Here is an example from PHPWebHosting:
|
||||
|
||||
###
|
||||
|
||||
# First we get their memberships
|
||||
|
||||
###
|
||||
|
||||
$memberships = $phpgw->accounts->memberships ($account_id);
|
||||
|
||||
###
|
||||
|
||||
# We determine if they're in their home directory or a group's directory
|
||||
|
||||
# If they request a group's directory, we ensure they have access to
|
||||
the group,
|
||||
|
||||
# and the group has access to the app
|
||||
|
||||
###
|
||||
|
||||
if ((preg_match ("+^$fakebase\/(.*)(\/|$)+U", $path, $matches)) && $matches[1]
|
||||
!= $account_lid)
|
||||
|
||||
{
|
||||
|
||||
$phpgw->vfs->working_id = $phpgw->accounts->name2id ($matches[1]);
|
||||
|
||||
reset ($memberships);
|
||||
|
||||
while (list ($num, $group_array) = each ($memberships))
|
||||
|
||||
{
|
||||
|
||||
if ($matches[1] == $group_array["account_name"])
|
||||
|
||||
{
|
||||
|
||||
$group_ok = 1;
|
||||
|
||||
break;
|
||||
|
||||
}
|
||||
|
||||
}
|
||||
|
||||
if (!$group_ok)
|
||||
|
||||
{
|
||||
|
||||
echo $phpgw->common->error_list (array ("You do not have
|
||||
access to group/directory $matches[1]"));
|
||||
|
||||
exit;
|
||||
|
||||
}
|
||||
|
||||
}
|
||||
|
||||
You should also check if the group has access to your appilcation.
|
||||
|
||||
6.3 Function aliases<sec:function_aliases>
|
||||
|
||||
You might have noticed there are some functions that just pass the
|
||||
arguments on to other functions. These are provided in part because
|
||||
of legacy and in part for convenience. You can use either. Here is
|
||||
the list (alias -> actual):
|
||||
|
||||
* copy -> cp
|
||||
|
||||
* move -> rm
|
||||
|
||||
* delete -> rm
|
||||
|
||||
* dir -> ls
|
||||
|
||||
6.4 Fakebase directory (changing /home)<sec:fakebase>
|
||||
|
||||
The old VFS was hard-coded to use "/home" as the fake base directory,
|
||||
even though the user never saw it. With the new system, crafty administrators
|
||||
may wish to change "/home" to something else, say "/users" or "/public_html".
|
||||
The fake base directory name is stored in $phpgw->vfs->fakebase, and
|
||||
changing it will transparently change it throughout the VFS and all
|
||||
applications. However, this must be done before any data is in the
|
||||
VFS database. If you wish to change it afterwords, you'll have to
|
||||
manually update the database, replacing the old value with the new
|
||||
value. Application programmers need to recognize that /home is not
|
||||
absolute, and use $phpgw->vfs->fakebase instead. I suggest setting
|
||||
$fakebase = $phpgw->vfs->fakebase; right off the bat to keep things
|
||||
neater.
