* applies new string literal convention in railties/libXavier Noria2016-08-061-4/+4
| | | | | The current code base is not uniform. After some discussion, we have chosen to go with double quotes by default.
* Fixes #25219Vipul A M2016-07-011-1/+1

* Move object allocation out of loopRichard Schneeman2014-09-271-4/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Right now BenchmarkCleaner allocates hundreds of strings on every request with an exception. This patch moves those strings to be generated at boot once and re-used. ## Bench Methods I took a modified form of CodeTriage https://github.com/schneems/codetriage-ko1-test-app/blob/master/perf.rake and ran given rake tasks with and without the patch to BacktraceCleaner. I made an endpoint results in exception ``` def index raise “foo" end ``` The gem `memory_profiler` was used to capture objects allocated for a single request. Then `benchmark/ips` was used to test the speed of the patch. You will see that we use less objects and the code becomes measurably faster with this patch. ## With patch: Memory for one request: ``` Total allocated 7441 Total retained 37 ``` Requests per second: ``` Calculating ------------------------------------- ips 4 i/100ms ------------------------------------------------- ips 43.0 (±4.7%) i/s - 216 in 5.037733s ``` ## Without patch: Memory used for one request: ``` Total allocated 11599 Total retained 35 ``` Requests per second: ``` Calculating ------------------------------------- ips 3 i/100ms ------------------------------------------------- ips 39.4 (±7.6%) i/s - 198 in 5.052783s ``` ## Analysis The patch is faster: ``` (43.0 - 39.4 ) / 39.4 * 100 # => 9 # % ~ speed bump ``` It also allocates less objects: ``` 11599 - 7441 # => 4158 ``` These strings are allocated on __EVERY SINGLE REQUEST__. This patch saves us 4158 objects __PER REQUEST__ with exception. Faster errors == Faster applications
