@stefano-maggiolo
it might be that you didn't install it, or that your system has some problem running it

@stefano-maggiolo, i can run isolate with terminal
minhphan@DESKTOP-RPEUH8I:~$ isolate
Please specify an isolate command (e.g. --init, --run).
Usage: isolate [<options>] <command>

Options:
-b, --box-id=<id> When multiple sandboxes are used in parallel, each must get a unique ID
--cg Enable use of control groups
--cg-mem=<size> Limit memory usage of the control group to <size> KB
--cg-timing Time limits affects total run time of the control group
(this is turned on by default, use --no-cg-timing to turn off)
-c, --chdir=<dir> Change directory to <dir> before executing the program
-d, --dir=<dir> Make a directory <dir> visible inside the sandbox
--dir=<in>=<out> Make a directory <out> outside visible as <in> inside
--dir=<in>= Delete a previously defined directory rule (even a default one)
--dir=...:<opt> Specify options for a rule:
dev Allow access to special files
fs Mount a filesystem (e.g., --dir=/proc:proc:fs)
maybe Skip the rule if <out> does not exist
noexec Do not allow execution of binaries
rw Allow read-write access
-D, --no-default-dirs Do not add default directory rules
-f, --fsize=<size> Max size (in KB) of files that can be created
-E, --env=<var> Inherit the environment variable <var> from the parent process
-E, --env=<var>=<val> Set the environment variable <var> to <val>; unset it if <var> is empty
-x, --extra-time=<time> Set extra timeout, before which a timing-out program is not yet killed,
so that its real execution time is reported (seconds, fractions allowed)
-e, --full-env Inherit full environment of the parent process
--inherit-fds Inherit all file descriptors of the parent process
-m, --mem=<size> Limit address space to <size> KB
-M, --meta=<file> Output process information to <file> (name:value)
-q, --quota=<blk>,<ino> Set disk quota to <blk> blocks and <ino> inodes
--share-net Share network namespace with the parent process
-s, --silent Do not print status messages except for fatal errors
-k, --stack=<size> Limit stack size to <size> KB (default: 0=unlimited)
-r, --stderr=<file> Redirect stderr to <file>
--stderr-to-stdout Redirect stderr to stdout
-i, --stdin=<file> Redirect stdin from <file>
-o, --stdout=<file> Redirect stdout to <file>
-p, --processes[=<max>] Enable multiple processes (at most <max> of them); needs --cg
-t, --time=<time> Set run time limit (seconds, fractions allowed)
-v, --verbose Be verbose (use multiple times for even more verbosity)
-w, --wall-time=<time> Set wall clock time limit (seconds, fractions allowed)

Commands:
--init Initialize sandbox (and its control group when --cg is used)
--run -- <cmd> ... Run given command within sandbox
--cleanup Clean up sandbox
--version Display program version and configuration
i don't know what my problem is

Stefano Maggiolo
@stefano-maggiolo
Try the same command as the error (with --init)
Also, when you ran cms, it should have left a directory with the sandbox and some debugging output, you can try looking in that and see if there's anything useful
Should be under /tmp/ something

@Nhatminh2442001_twitter
minhphan@DESKTOP-RPEUH8I:~$ isolate --init
/var/local/lib/isolate/0
is it normal ?
Phan Nhật Minh
@Nhatminh2442001_twitter
i found nothing in tmp/cms-compile-unf2s49w @@
Stefano Maggiolo
@stefano-maggiolo
yep that's normal
the other thing that this might be is that the user you use for CMS is not in the group that can run isolate as root
would be strange since mihphan can
but check, if you have a weird setup where you run CMS as another user

@andreyv
What is the use case for multiple submission files in Batch task type (and, I guess, in Communication as well)?
Phan Nhật Minh
@Nhatminh2442001_twitter
@stefano-maggiolo thanks, problem solved
but i found new problem with RWS
14:48:36 WARNING ProxyService,0 Status 400 while sending submissions to ranking http://usern4me:passw0rd@localhost:8890/.
Stefano Maggiolo
@stefano-maggiolo
@andreyv IIRC some tasks call for two functions in different files - not that it changes anything, they will just compiled together
@Nhatminh2442001_twitter care to share the solution for future readers?
for that error: I assume you have started RWS with the same arguments - if so, you should be able to see the error in the RWS logs
Phan Nhật Minh
@Nhatminh2442001_twitter
@stefano-maggiolo i used sol of 'https://github.com/cms-dev/con_test' to submit it, i dont't know what to do next
Stefano Maggiolo
@stefano-maggiolo
Phan Nhật Minh
@Nhatminh2442001_twitter
@stefano-maggiolo yes, i did but i think when i use default config and will not do anything
Stefano Maggiolo
@stefano-maggiolo
not sure I understand - if you launched RWS, when ProxyService gives you that error, do you see any logs in RWS?
if not, then there is probably a mismatch in the address
between the configuration of PS in cms.conf and that of RWS in cms.ranking.conf

@stefano-maggiolo
mmm
for some reason the current data PS wants to send is imcompatible with the existing data in RWS
the easiest way is to clear the data in RWS
Andrey Vihrov
@andreyv
@stefano-maggiolo Thanks. Regarding multiple sources, something doesn't seem right here: https://github.com/cms-dev/cms/blob/master/cms/grading/languages/python3_cpython.py#L62
Suppose the submission format is two files, hello.%l,extra.%l. If something in extra.%l tries to import hello, then it will break because the file was renamed to __main__.pyc.
Stefano Maggiolo
@stefano-maggiolo
oh well
YMMV :)
you're going into a case which is the intersection of many rare cases
  1. multi-file batch
  1. using python
  1. with the need of the two file calling each other
in particular I think file calling each other is very rare - if you had that, you probably asked for a single file
Andrey Vihrov
@andreyv
yeah, well, I don't like leaving any open corner cases 😄
Stefano Maggiolo
@stefano-maggiolo
true, but you have to cut a line somewhere between what you want to support and what you drop
you'll always have corner cases when dealing with turing complete arbitrary inputs
(#notatheorem)
Andrey Vihrov
@andreyv
Anyway, this renaming of exactly one file does look a bit weird
Stefano Maggiolo
@stefano-maggiolo
I think it was done to allow to run the python code from the zip file
i vaguely remember that we looked for something like that but passed due to some issue - maybe only available for a high version of py3k?
anyway, if there's a better alternative I'm not opposing
Andrey Vihrov
@andreyv
Well, without requiring packages the "correct" solution is manually writing a __main__.py file which will import the first file
Which may or may not be overkill
Stefano Maggiolo
@stefano-maggiolo
(looking at the PR I don't see any comment relative to my vague recollection)
That won't work if your submission format is main.%l 😆
