Overview
Google's RE2
_ regex engine. The regex string must adhere to the documented
syntax
_. The engine is designed to complete execution in linear time as well
as limit the amount of memory used. Envoy supports program size checking via
runtime. The runtime keys re2.max_program_size.error_level
and re2.
max_program_size.warn_level
can be set to integers as the maximum program
size or complexity that a compiled regex can have before an exception is
thrown or a warning is logged, respectively. re2.max_program_size.error_level
defaults to 100, and re2.max_program_size.warn_level
has no default if
unset (will not check/log a warning). Envoy emits two stats for tracking the
program size of regexes: the histogram re2.program_size
, which records the
program size, and the counter re2.exceeded_warn_level
, which is incremented
each time the program size exceeds the warn level threshold.

#max_program_size ⇒ Fixnum
This field controls the RE2 "program size" which is a rough estimate of how complex a compiled regex is to evaluate.

-
#initialize(**args) ⇒ GoogleRe2
constructor
A new instance of GoogleRe2.
-
#update!(**args) ⇒ Object
Update properties of this object.

Instance Attribute Details
#max_program_size ⇒ Fixnum
This field controls the RE2 "program size" which is a rough estimate of how
complex a compiled regex is to evaluate. A regex that has a program size
greater than the configured value will fail to compile. In this case, the
configured max program size can be increased or the regex can be simplified.
If not specified, the default is 100. This field is deprecated; regexp
validation should be performed on the management server instead of being done
by each individual client.
Corresponds to the JSON property maxProgramSize
