What is SIP?

The current-directory when you launch Factor.app is set to "/", which is 
probably why your URL is defaulted to that. 

Maybe would be nicer to have it set to your home directory which you could do 
in your .factor-rc or on startup of the listener:

home current-directory set-global

[Factor-talk] El Capitan bug-feature bites normalize-path

[CW Alston]

Greetings -

I’d been merrily downloading videos via extra/youtube until I got a

new MacBook Pro & too hastily upgraded to El Capitan. Among other

inconveniences I’ve had to work around because of SIP, the
``download-video’’

word now produces a permissions error:

———-

--- Data stack:

"FfViCWntbDQ"

IN: scratchpad download-video


Unix system call “open” failed:


Permission denied (13)


It was called with the following arguments:


"/Buckminster Fullers Jitterbug.mp4"

1537

438

———-


Digging into the code, I see  that ``normalize-path’’ aims at the “/’’
mount-point

as the current directory for the Unix ``open’’. But SIP won’t allow
modifying

that location without authentication, so ``download-video’’ fails.


If I wrap the code in a ``with-directory’’ combinator setting an allowable

current  directory, I’m back in business:

———-

IN: youtube

SYMBOL: my-youtube-prefix

my-youtube-prefix [ "/Users/cwalston/YouTube/videos" ] initialize


: download-video ( video-id -- )

[ my-youtube-prefix get ] dip! ( -- path video-id )

[ get-video-info

   [

 video-formats [ "type" of "video/mp4" head? ] find nip

 video-download-url

   ] [

   "title" of sanitize ".mp4" append download-to

   ] bi

] curry with-directory ;

———-


It’s actually nicer to be able to set a target download directory, so I
should

thank SIP for goading me out of my laziness. I haven't hunted down all the
spots

where ``normalize-path’’ may choke on the strictures of SIP, but I suspect
this

isn't the last time El Cap will bite working code.
