WAMP is a perverted forward-backronym from LAMP, for people who want to do web development, but have some overriding reason to use Microsoft Windows (generally corporate IT policy). To test a web site on Windows, I have a VirtualBox instance set up for my by ievms, and naturally I need to copy files on to it. Which is a problem, because Windows is terrible at that sort of complicated system administration.
Plan A: Shared Folder
My first attempt to test this on Windows was to set up a shared directory using VirtualBox. I followed their instructions, even read their moderatley putrid manual, and nothing worked. I Googled to see if other people had solutions to this and discovered (as is usual with Windows problems) all the solutions were variations on following the recipe in the manual, with no discussion of what to do if it fails.
Plan B: Rsync
So I decided to try instead to copy the files in to the virtual disk of the virtual PC. If my test server were Linux this would be something like:
rsync -e ssh -av deploy/ firstname.lastname@example.org:Sites/foo/
The advantage of using rsync is that you can do it repeatedly and only the changed parts of changed files get copied, which over a network is much faster. Since Windows does not have rsync as standard, I spent some time looking for third-party rsync implementations. So far as I was able to tell, my options are as follows:
- install all of Cygwin;
- a GUI that thinks rsync is for backups only; and
- a GUI that uses its own protocol rather than rsync.
Cygwin is all about solving the problem that you are not using Unix by installing something a bit like Unix on Windows. The third option is a non- starter. I tried the second one. Unfortunately its UI was built around the idea that you are using it to back up one Windows box on to another, it does not have a command line, and in the end I stopped trying to make it useful.
Plan C: PuTTY
Having given up on having just one copy of the files, I now gave up on having efficient copying, and switched to using PuTTY’s implementation of Scp. PuTTY exemplifies as much as anything the inadequacies of Windows for web development: in order to do two basic things, copying files to your server and logging in to your server to set it up, you need to install a third-party application from someone’s personal web pages and with a version number of 0.62. And once you have done so, PuTTY is the most useful piece of software on your miserable Microsoft-certified genuine-Windows computer.
Now with PuTTY installed, I start up a command window and type
"C:\Program Files\PuTTY\pscp.exe" email@example.com:deploy.zip Desktop
This puts the ZIP file on the desktop where I can double-click it to open it,
then drag and drop the toplevel folder on to the
C drive icon in the left
panel of the Explorer window to extract the files with the minimum of mousing.
This is a throwaway server, so there is reason not to use the toplevel of the
C drive to store the application files. The main risk is that Windows moves
the icons in the left sidebar around while you are dragging, which may cause
the files to end up in the wrong place.
Even better, each time I need to tweak something during the test I get to do the whole nonsense all over again, because I can’t properly automate any of this stuff. I discovered a useful feature of the ZIP program though. My actual script for creating the deploy archive looks like this:
rsync --delete -avC \
--exclude cookbooks --exclude tests --exclude phpunit.* --exclude Vagrantfile \
… more exclusions …
zip -r full deploy --difference-archive --out incr.zip
zip -rq full deploy
This creates two deployment files,
full.zip is the complete set, whereas
incr.zip is the files added to
full.zip since last time. This makes the
transfer-and-unpack process run faster, because copying files around in a
Virtual PC is pretty slow.
Oh, and every so often my copy of Windows spontaneously reboots in the middle of a file transfer, just to remind me how wonderful Windows isn’t as a development platform.
Plan D. FTP
I did not need to resort to this, but I have in the past when both ends of the transaction are Microsoft Windows:
- Copy the ZIP file to my personal web server with FTP from my development machine.
- Copy the ZIP file from my personal web server with the
ftpcommand on the virtual PC.
In other words, to cross the gulf between my desktop and a virtual PC in my office, go via my node in a datacentre in London.
Updated 2012-10-17 to add the
--difference-archive fiag for the
zip command and Plan D.
