SVN Error E175002

I have been plagued by this error in subversion particularly when trying to commit from some of the boxes which I use less frequently:

svn: E175002: Unexpected HTTP status 200 ‘OK’ on ‘POST’ request to ‘/svn/!svn/me’

I have spent hours doing searches, reading posts, but have never found anyone whose issue was exactly like mine, not been able to figure it out based on other peoples issues. I resolved today to pay serious attention to figuring it out.

The solution turned out to be related to the url I used when I check something out of the svn repository. Long ago I set up a cname in dns for, and for a long time I used it. There is an apache config file for the servername, and it redirects http to https. Then at some point I began to just use… to check things out. And that is where I went wrong, because that will work fine to do checkout, but when I try to commit from a box with that url ( the http request is being routed to the default server, and the setup of the SSL session is failing.

I’m unsure exactly what is happening to cause the request to go to the default server. Perhaps the commit request does not specify SNI information.

What I do know is how to fix it. Do the checkout with and commits work fine.

Running Apache under my username

I had some trouble on the development box with permissions and decided it would be “easy” to just have apache run under user dee, that would just make everything so much easier. Right.

Two things have come up so far, and more likely to follow. One, I had to change the ownership on /var/lib/php/session from apache to dee. Second, I had to add dee into tlsusers so the media stuff can read the certificate.

This may have been a bad idea.

1/31/18: Went back to using apache user, when I moved to Fedora 27. Fedora now uses php-fpm service, and now apache needs to open a socket to it, and it just became complicated.

GTK Tooltips and Eclipse

Eclipse on Fedora (and as I read it, also on Ubuntu) has now got a problem with colors. Specifically, when one hovers over a function to obtain the calling sequence, a pop up appears to provide this information but the background of the pop-up is black, which makes the content unreadable. This is relatively new, though I’m not sure whether it was with the change to Eclipse Neon or earlier, or the change to Fedora 24.

It turns out this is not a setting in eclipse, although I wasted quite a lot of time looking for it. This ends up being a system setting, associated with gtk, the graphical toolkit. If one starts eclipse with

export SWT_GTK3=0;eclipse

which starts eclipse with gtk 2.0, instead of gtk 3.0, the problem goes away, the background of the pop-ups becomes a nice cream color.

The settings we are using are set in the theme one chooses, the default theme being Adwaita. The themes are kept in /usr/share/themes. I tried simply changing to a different theme (TraditionalOk) but the setting affecting this did not change. So I resorted to force.

In /usr/share/themes/TraditionalOk there are directories for gtk-2.0 and gtk-3.0. Within gtk-3.0 I changed the file gtk-widgets.css, specifically, I changed the setting in the tooltip section to background-color #f5f5b5; Previously the value was “@theme_tooltip_bg_color;” and as I read it, that define ought to have the value #f5f5b5. But something is wrong, and the setting is disruptd. But forcing it this way, it seems to work.
