[REBOL] CGI directory access questions
From: jason:cunliffe:verizon at: 4-Sep-2002 19:15
Rebol CGI Permissions 101
I guess..
I can now upload files happily via http, using Andreas' multipart/form script.
But still need help understanding how basic file and directory permissions work
from rebol CGI.
Example: When I login and run my %testupdir.r script from the bash shell it
works OK:
----------------------
#!/home/rebol/rebol -cs
REBOL []
print "Content-type: text/html^/^/"
message: "hello testing writing to a directory via cgi script"
append message rejoin [newline read %. " " now/time]
updir: %uploads/
filename: %testupdir.txt
filepath: join updir filename
write filepath message ; does not work from CGI
;write filename message ; works from CGI
quit
----------------------
Login and then running script manually from REBOL shell works too, but I get
security prompt:
>> now
== 4-Sep-2002/18:44:08-4:00
>> do %testupdir.r
REBOL - Security Check:
Script requests permission to open a port for read/write on:
/web/turbulence/www/Works/trees/vanilla/uploads/testupdir.txt
Yes, allow all, no, or quit? (Y/A/N/Q) Y
>> read %uploads/testupdir.txt
== {hello testing writing to a directory via cgi script
18:44:27longpath}
BUT, when I call it as CGI directly in a browser url, it returns this error:
** Access Error: Cannot open
/web/turbulence/www/Works/trees/vanilla/uploads/testupdir.txt ** Where: do-boot
** Near: write filepath message
However, if I change script above instead to write into the current directory,
then its OK!
Q1: What do I need to do to so my script has permissions to run from CGI and
read/write into a subdirectory?
Q2: Why does it work ok as bash shell executable, but needs manual confirmation
in REBOL shell.
Q3: What options are there for controlling these permissions?
Q4: What checks can I run in rebol CGI scripts to check permission first for
directories
=> create, read, or write
thanks
