resolve ram¶

Synopsis¶

codeql resolve ram [--ram=<MB>] <options>...

Description¶

[Deep plumbing] Prepare RAM options.

This deep plumbing command prepares appropriate command-line options to start a subcommand that will execute a QL query evaluator. It knows appropriate heuristics for deciding whether to keep some of the configured memory outside the Java heap.

In particular, this should be used to find appropriate -J-Xmx and --off-heap-ram options before staring a query server based on a desired total RAM amount.

Options¶

--format=<fmt>¶

Select output format. Choices include:

lines (default): print commmand-line arguments on one line each.

json: print them as a JSON array.

Options from the invoking command’s command line¶

-M, --ram=<MB>¶: Set total amount of RAM the query evaluator should be allowed to use.

Common options¶

-h, --help¶: Show this help text.

-J=<opt>¶

[Advanced] Give option to the JVM running the command.

(Beware that options containing spaces will not be handled correctly.)

-v, --verbose¶: Incrementally increase the number of progress messages printed.

-q, --quiet¶: Incrementally decrease the number of progress messages printed.

--verbosity=<level>¶: [Advanced] Explicitly set the verbosity level to one of errors, warnings, progress, progress+, progress++, progress+++. Overrides -v and -q.

--logdir=<dir>¶

[Advanced] Write detailed logs to one or more files in the given directory, with generated names that include timestamps and the name of the running subcommand.

(To write a log file with a name you have full control over, instead give --log-to-stderr and redirect stderr as desired.)
