OK, I’m probably not the first person to attempt to put together a PHP web-based interface to rsync to ease deployment, but there goes.
We have a ‘QA’ server locally and a ‘Staging’ server at Rackspace. I’ve set up SSH key pairings so I can rsync between the two servers and it all works great. The problem is that rsync is a bit flaky as to what it decides needs updating.
The script I have written first executes rsync with the ‘–dry-run’ parameter to get a list of everything that needs transferring. The command is as follows:
$strCheck = shell_exec(
"rsync " .
"--verbose " .
"--recursive " .
"--safe-links " .
"--checksum " .
"--dry-run " .
"--delete " .
"--delete-excluded " .
"--force " .
"--cvs-exclude " .
"--human-readable " .
"/apps/{$system}/ " .
"user@liveserver:/apps/{$system}_staging/"
);
Now this all works fine and I can parse the string that’s returned into stuff that needs deleting and stuff that needs adding/updating. I then construct a HTML table that automatically indents each checkbox based on where it is in the hierarchy. I also use a bit of javascript so I can allow the user to select all files in a folder.
If a folder itself is to be added/deleted, it includes it in the list. For example:
/newfolder/
/newfolder/file1.php
/newfolder/file2.php
which is great, because ‘/newfolder/’ will be displayed with one indent and ‘/newfolder/file1.php’ and ‘/newfolder/file2.php’ will each be displayed with two indents underneath ‘/newfolder/’. The checkbox next to ‘/newfolder/’ will automatically select the two ‘child’ files and everyone is happy.
However, if it is just adding/updating files to a folder, it omits the folder itself:
/oldfolder/filea.php
/oldfolder/fileb.php
…
Which means all the files in ‘/oldfolder/’ will have two indents, but there is no visible mechanism with which to select all the files in the folder.
So my question is this: is there something I am missing in the available rsync parameters where I can force it to include the folder for any updated files, or am I going to have to add them in as I loop through the array? If it’s the latter, what would be the best way of doing that?
Help me Obi Stack Overflowbi, you’re my only hope…
Since the directory does not need to be created or deleted it will be missing from the list rsync returns. I don’t believe there is any way to fix that.
I think your best bet would be to get the paths something like this
$path = explode(PATH_SEPARATOR, dirname($filename) );
Where $filename is your files name.
