GVFS mount points, or, how to completely ignore usability while building a usability feature.

Posted by KarlP on 22 December, 2016 2 comments

Gnome happily mounts my phone’s MTP shares for me. I can even browse for them in “files” and drag and drop and everything. It’s pretty cool. And, magically, behind the scenes, it even exists in the filesystem so I can use rsync and cp and things.

But the mount point…. Oh boy. What on earth were they thinking. /run/user/1000/gvfs/mtp\:host\=%5Busb%3A002%2C010%5D/
Are you fucking kidding me? That’s an url encoded way of saying [usb:002,010] Why did it need to be url encoded? No idea. What about the content? Oh, that’s the USB bus, and device address. Spectacular. That means it depends on not only what physical port it’s plugged into, but what order it was plugged in. (And that unplugging and replugging will make a new path) Let’s not use things like iManufacturer, iProduct, iSerial, vid, pid, anything actually device specific no, not here.

I’m sure this was done to try and ensure that the mount point would be unique. Great. Mission accomplished. However, it could be made unique, and usable at the same time. And then this thing, that exists out of a usability feature, would actually be more usable.

Facebook share scraping image selector open graph woes

Posted by KarlP on 20 September, 2015 None comments

So, the share buttons on my website have been giving blank images, or the wrong images for a while. You’re meant to go and add a whole bunch of OpenGraph meta tags, but W.T.F the tag for the image to use must be absolute. wat

No, really, WAT. For double fun wat, it must include the protocol too! You have to use a second tag if you want to use https!

So, using the “modern” og:image tags is just right out then. (for realz, who the fuck though absolute urls were a good idea. I generate galleries, the galleries just run on disk, you don’t need to know where in the site they’re mounted or anything) Web browsers themselves are perfectly capable of loading a relative url image. Facebook’s Object Debugger on the other hand, not so much. It will take an img with src=../blah.jpg" and turn it into http://domain/blah.jpg, completely ignoring the path sections.

However… it can deal with relative urls that don’t have .. in them. “src=img/blah.jpg” is perfectly ok. Dumb, dumb and dumber.

<img src="../blah.jpg"> FAIL
<img src="blah.jpg"> GOOD
<img src="relative/blah.jpg"> GOOD

WAT

SELinux is teh suck – I’ve given up.

I tried, I really did. I let the selinuxtroubleshooter run, I added exceptions, I tried to do it’s bidding and be a joyful comrade marching forwards to a secure perfect future. I’ve given up. Fuck this shit. The last straw was installing nginx, to serve up a few virtual hosts in the form of /home/domain/subdomain/{site,logs}
Errors in the journal like SELinux is preventing /usr/sbin/nginx from getattr access on the file . and then how to run grep on a log and feed it an audit tool that generates exceptions. Oh yes, that’s actually how you’re meant to do things. From past experience I knew it would only allow the first layer of the onion to unpeel and I’d have to keep adding exceptions, so I looked into what it was really complaining about.

Missing labels on THE ENTIRE WEBROOT labelling them as “httpd_sys_content_t” Right. Go fuck yourself SELinux. chcon -Rt httpd_sys_content_t /home/blah/wop No. No. No. I get it, you were only trying to stop me from inadvertently starting a webserver and…. serving web content… Actually, no, that’s not it. I was very fucking explicitly trying to start a webserver. I’d installed nginx, I’d added configs for the virtual hosts, and restarted nginx. That’s pretty damn explicit.

So, I gave up, I set SElinux to “permissive” so I could maybe see logs, and maybe feel inclined to work with it again in the future. But to avoid rebooting, I then did the old “echo 0 > /sys/fs/selinux/enforce” and then restarted nginx again. Now nginx works, but… now the journal is full of “detected unhandled Python exception in ‘/usr/sbin/setroubleshootd'” and stack traces following. So it’s over SELinux. You’re beyond dead to me, and I really, really tried to make it work.

oracle destroying sun

Oh oracle, how I dislike thee. You took a perfectly good url like: “http://forums.sun.com/thread.jspa?threadID=5147616” clearly referencing a single thread, and you THREW IT AWAY giving me
http://forums.oracle.com/forums/main.jspa;jsessionid= 8d92079030d6c653c4adf7d34c40af87cbfdff6c4e77.e38Qb3qMa3eRbO0LaNqQaNaQax0Qe0?categoryID=84

And that just drops me at the root of _ALL_ the oracle forums.

Good job. Good fucking job.

WebMethods Designer 8 – take 2

Well, it’s still pretty crap. Here’s some more things that are just wrong/stupid.

  • The navigation tree on the left helpfully scrolls to the current flow. Except that it actually scrolls so that the top of the folder containing the current flow is at the top of the tree view. So for a folder with (too) many flows, the current flow is actually off the bottom of the screen.
  • To see your currently locked elements, you need to scroll to the very top, right click the server and choose properties.
    Fine, except that you can’t double click on an entry to go to that flow, and the dialog is modal, so you have to keep opening and closing it to have a list of what’s locked. Or, take a damn screenshot.

Doesn’t matter whether I’m using the stock version, based on eclipse 3.4, or installed into a working eclipse 3.6.
