Typically SQL is not a great place to store a counter that is incremented often. For instance if you're counting the number of visits to a page by incrementing a SQL column and that page gets popular then there's a good chance that the SQL counter will become a benchmark. This is because doing an UPDATE on the row in question locks the row during the course of the UPDATE. So for many concurrent UPDATES there will be lots of lock contention. This gem helps with that.
= Cirron Cirron measures a piece of Ruby code and reports back several performance counters: CPU instruction count, branch misses, page faults and time spent measuring. It uses the Linux perf events interface or @ibireme's KPC demo[https://gist.github.com/ibireme/173517c208c7dc333ba962c1f0d67d12] on OSX. It can also trace syscalls using +strace+, Linux only! == Prerequisites - Linux with perf events support / Apple ARM OSX - C++ - Ruby 3.x == Usage === Performance Counters $ sudo irb irb(main):001> require 'cirron' => true irb(main):002* c = Cirron::collector do irb(main):003* puts "Hello" irb(main):004> end Hello => Counter(time_enabled_ns: 110260, instruction_count: 15406, branch_misses: 525, page_faults: 0) === Tracing Syscalls $ sudo irb irb> require 'cirron' => true irb> trace = Cirron::tracer do irb> # Your code here irb> puts "Hello" irb> end => [#<Syscall:0x00007c6c1a4b3608 @args="1, [{iov_base=\"Hello\", iov_len=5}, {iov_base=\"\\n\", iov_len=1}], 2", @duration="0.000201", @name="writev", @pid="2261962", @retval="6", @timestamp="1720285300.334976">] # Save the trace for ingesting to Perfetto irb> File.write("/tmp/trace", Cirron::to_tef(trace)) => 267 === Tampering with Syscalls Available tampering actions are: error: Inject a fault with the specified errno. retval: Inject a success with the specified return value. signal: Deliver the specified signal on syscall entry. delay_enter: Delay syscall entry by the specified time. delay_exit: Delay syscall exit by the specified time. poke_enter: Modify memory at argN on syscall entry. poke_exit: Modify memory at argN on syscall exit. syscall: Inject a different syscall instead. The when argument can be used to specify when to perform the tampering. See the Tampering section of the [strace manual page](https://man7.org/linux/man-pages/man1/strace.1.html) for more detailed explanaition of the arguments. ``` $ sudo irb irb> require 'cirron' irb> injector = Cirron.injector irb> injector.inject("openat", "error", "ENOSPC") irb> injector.inject("openat", "delay_enter", "1s", when_condition="2+2") irb> injector.run do irb> # Open now fails with "No space left on device" and every irb> # other call to `openat` will be delayed by 1s. irb> File.open("test.txt", "w") irb> end ``` == Additional Information For more detailed information, please visit the project's GitHub page: https://github.com/s7nfo/Cirron
