jackjackdripper: Would you mind elaborating on "call ruby from an app"?

In the C API, does rb_rescue get called only after any in-script rescue blocks are checked? I.e. is it the outer-most handler, or inner most?
<scorp007>
I think I'm seeing it get called before the script handler gets a chance.
<scorp007>
I called rb_rescue2 with the top-level exception class to implement an "unhandled exception filter" in my embedding

rescues are called from the most specific to the least, innermost to outermost when equal specificity.

debug.rb has a require 'readline' in a rescue block. They filter for LoadError. I don't have readline on my system, so a LoadError is raised

sarmiena_: You definitely need to update OpenSSL to a secure version. Then build Ruby against it. (Beware if you're using rbenv to build that you must update ruby-build because it ships its own OpenSSL instead of using your package manager's).

Let's say I have a file named foo.txt. Now I have a Ruby program running that has this file opened like f = File.open('foo.txt'). Another application on the system now deletes and recreates that file and I need Ruby to reopen the file, but how can I find out if the file has been recreated? My File object returns false on .closed? and always true for .eof? after the file recreation and after writing contents into the new file
<Neon>
so it does neither complain about the old fd to not exist anymore nor does it automatically open the new file.

imperator: I'd create a copy :-/
davedev2_ has quit [Ping timeout: 256 seconds]
<imperator>
or that
<imperator>
atmosx, what happens if the file is replaced before the copy finishes?
<Neon>
Well, it's a logfile I want to watch and wait until the application that writes to it appends a line of a specific pattern. The problem is that the application automatically archives the logfile and creates a new one (on the same path) on day change.
rideh has quit [Quit: zap]
<Neon>
So it might happen that I start watching the logfile on day 1 and will never go on, because the application writes the wanted line on day 2 in the recreated file and the old one I've opened in Ruby will be eof forever.
gamename has quit [Ping timeout: 265 seconds]

A case-specific solution for that would be a time check of course, but I couldn't believe that Ruby can't notice if a file has been deleted. I mean the file descriptor (OS-wise) should become invalid, shouldn't it?

rakm has quit [Quit: My MacBook Pro has gone to sleep. ZZZzzz…]
<Antiarc>
The file isn't fully deleted until all handles to it are closed, the FD is still valid, it's just not associated with that name anymore
<Antiarc>
If you execute lsof after deleting the file but while ruby still has a handle to it, you'll see it show up as still open but marked as deleted
xfbs has quit []
<Antiarc>
(this is why you have to rotate logs after deleting files to reclaim the space used by them)
<atmosx>
imperator: good question, well if that's even remotely plausible you should lock the file
<Antiarc>
rather, you have to reopen any handles to those filenames

that's a good point, something like rb-inotify should let you see when that happens
