Now you can specify multiple filters for RUBY_DEBUG_LOG output by RUBY_DEBUG_LOG_FILTER=a,b,c (in this case, logs that the function name contains a, b or c).

/* RUBY_DEBUG_LOG: Logging debug information mechanism
|
|
*
|
|
* This feature provides a mechanism to store logging information
|
|
* to a file, stderr or memory space with simple macros.
|
|
*
|
|
* The following information will be stored.
|
|
* * (1) __FILE__, __LINE__ in C
|
|
* * (2) __FILE__, __LINE__ in Ruby
|
|
* * (3) __func__ in C (message title)
|
|
* * (4) given string with sprintf format
|
|
* * (5) Thread number (if multiple threads are running)
|
|
*
|
|
* This feature is enabled only USE_RUBY_DEBUG_LOG is enabled.
|
|
* Release version should not enable it.
|
|
*
|
|
* Running with the `RUBY_DEBUG_LOG` environment variable enables
|
|
* this feature.
|
|
*
|
|
* # logging into a file
|
|
* RUBY_DEBUG_LOG=/path/to/file STDERR
|
|
*
|
|
* # logging into STDERR
|
|
* RUBY_DEBUG_LOG=stderr
|
|
*
|
|
* # logging into memory space (check with a debugger)
|
|
* # It will help if the timing is important.
|
|
* RUBY_DEBUG_LOG=mem
|
|
*
|
|
* RUBY_DEBUG_LOG_FILTER environment variable can specify the filter string.
|
|
* If "(3) __func__ in C (message title)" contains the specified string, the
|
|
* information will be stored (example: RUBY_DEBUG_LOG_FILTER=str will enable
|
|
* only on str related information).
|
|
*
|
|
* In a MRI source code, you can use the following macros:
|
|
* * RUBY_DEBUG_LOG(fmt, ...): Above (1) to (4) will be logged.
|
|
* * RUBY_DEBUG_LOG2(file, line, fmt, ...):
|
|
* Same as RUBY_DEBUG_LOG(), but (1) will be replaced with given file, line.
