Yeah, that's where I've got them, but in order for apache to write generated
files, it still needs full perms. Turns out to be the same whether they
are in ~/public_html or /var/www<br>

<p class=MsoNormal>I've complained about this before, but I'm still hoping
somebody can tell me something I don't know.<br>
<br>
I'll skip the details and just say the situation is that a programmer is
developing a web app, but the web app also does code generation, so the
programmer (a regular linux user) must have full control over the files, but
the apache process (www-data on ubuntu) must also have full control.<br>
<br>
This is only on a dev workstation, the situation can be avoided on a production
server but not on a dev workstation.<br>
<br>
Here is the question: It seems to me that everything about Linux is set up to
prevent this from happening without major interventions that a newer Linux user
will not understand and a veteran will consider inappropriate. Am I
missing something? Is there a simple way to give two users full control
over a body of files? Don't just say "groups" automatically,
see below:<br>
<br>
METHOD 1: <br>
<br>
1) Add the programmer's user account to the www-data group (veterans may
object, newbies may stumble)<br>
2) Put perms to 6770 on the file tree<br>
3) Set ownership to <user>:www-data on the file tree<br>
<br>
This is what I am doing now. Believe it or not this is as simple as I
could figure it, but I'm shooting for simpler.<br>
<br>
METHOD 2:<br>
<br>
This gives the veterans fits, but I figured <i>on a dev workstation</i> I would
just run apache as my account. This is <i>more invasive</i>, but <i>only
at a single point</i>. At this point the veterans jump in with
"never, never, never" but don't usually address the context of the
situation, so I don't know what to do with their advice. <br>
<br>
<br>
METHOD 3:<br>
<br>
Complex ACL's. There seems to be on-off support for more complex file
permissions in Linux, but I get the sense it is a red-headed stepchild.
If there were a more powerful permissions system that understood the idea of
giving two separate users the same permissions, I'd be very happy to accept a <i>configurable
dependency</i>, but I don't get the idea that's out there.<br>
<br>
So I'm really hoping I missed something in the last 10 years on how linux
controls file permission :(<br>
