Am I the only one having the issue of cms services stopping? All of them are closed, the SSH session I'm using to connect to it closes, but the system doesn't restart (or at least it shouldn't according to uptime
(I'm using Ubuntu Server 18.04, cms v1.4.rc1)
For example, last night I was adding tasks until 9:00, and according to the log(https://paste.ubuntu.com/p/k2sbFtzbqn/), at 9:30 the services stop. Any ideas on what may be causing this? It has happened more than once (all of the times that this has happened have been after inactivity, but it may just be a coincidence)
Currently multiple programming language plugins such as Python and Java go to extra lengths to work with an extensionless executable file name. I would like to introduce a Language.executable_extension()
method and use it to prepare executable names in task plugins. Somewhere here:
https://github.com/cms-dev/cms/blob/d4c9e926bd52d8022069c417b206b0882ef4d1ba/cms/grading/tasktypes/Batch.py#L172
In the end this would allow to simplify compilation/evaluation commands for multiple languages.
Does this sound good to work on?
hello everyone, i have some problems when submit file, please help me

@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
