JavaScript

Synchronet's JavaScript settings can be adjusted in the Synchronet for Windows Control Panel File->Properties->JavaScript tab:

The following .ini files contain the Synchronet JavaScript configuration settings:

Key Default Value Description
JavaScriptMaxBytes 16MB Maximum run-time heap size (per script invocation)
JavaScriptTimeLimit 864000 Maximum total execution time of a script (in 1/10th second units, 0=disabled)
JavaScriptGcInterval 100 Garbage collection interval (in “operation callbacks”, 0=disabled)
JavaScriptYieldInterval 10000 Time-slice yield interval (in “operation callbacks”, 0=disabled)
JavaScriptLoadPath load Directories (comma-separated) to search for JS load-libraries
JavaScriptOptions JIT | COMPILE_N_GO See Options below

Notes

JavaScriptTimeLimit

Default: 864000 (24 hours)

Maximum number of ticks (100ms) before auto-termination of a JavaScript script (i.e. infinite loop detection).

Set to 0 for unlimited time (disables infinite loop detection).

Note: This key replaces the old JavaScriptBranchLimit key which is no longer used (as of Synchronet v3.16).

JavaScriptGcInterval

Default: 100

JavaScript Garbage Collection interval (in ticks).

Set to 0 for never.

JavaScriptYieldInterval

Default: 10000

Time-slice yield interval (in ticks).

Set to 0 for never.

JavaScriptLoadPath

Default: load

Comma-separated list of load paths (relative to exec or mods directories).

These are the directories/sub-directories where the JavaScript load() method will search for filenames to be loaded by other scripts.

Options

JavaScript compiler options may be controlled via the JavaScriptOptions bit-field key value. Multiple option flags may be specified by bit-wise ORing them together with the | symbol.

Option Description
STRICT Warn on dubious practice (similar to “use strict”)
WERROR Convert warnings to fatal errors
VAROBJFIX Use the last object of scope chain as the ECMA 'variables object'
COMPILE_N_GO Compile-time scope chain resolution of consts
RELIMIT Disallow excessively recursive regular expressions
ANONFUNFIX Disallow function () {} in statement context per ECMA-262 Edition 3
JIT Enable TraceMonkey just-in-time compiler
METHODJIT Enable JägerMonkey just-in-time compiler
PROFILING Use profiler to choose between TraceMonkey and JägerMonkey at run-time
METHODJIT_ALWAYS Always use the JägerMonkey JIT compiler (don't tune at run-time)

The default JavaScript option flags (when the key is not specified) are:

JIT | COMPILE_N_GO
