Process.clock_gettime allows getting the real time in nanoseconds as
well as allowing one to get a monotonic timestamp. This offers greater
accuracy without the overhead of having to allocate a Time instance. In
general using Time.now/Time.new is about 2x slower than using
Process.clock_gettime(). For example:
require 'benchmark/ips'
Benchmark.ips do |bench|
bench.report 'Time.now' do
Time.now.to_f
end
bench.report 'clock_gettime' do
Process.clock_gettime(Process::CLOCK_MONOTONIC, :millisecond)
end
bench.compare!
end
Running this benchmark gives:
Calculating -------------------------------------
Time.now 108.052k i/100ms
clock_gettime 125.984k i/100ms
-------------------------------------------------
Time.now 2.343M (± 7.1%) i/s - 11.670M
clock_gettime 4.979M (± 0.8%) i/s - 24.945M
Comparison:
clock_gettime: 4979393.8 i/s
Time.now: 2342986.8 i/s - 2.13x slower
Another benefit of using Process.clock_gettime() is that we can simplify
the code a bit since it can give timestamps in nanoseconds out of the
box.
In any case if just want the value which is always ‘gitlab’
require 'benchmark/ips'
Project.first # To load database things
GitlabIssueTrackerService.first # To load database things
Benchmark.ips do |x|
x.config(:time => 5, :warmup => 2)
x.report("current") do
Project.new.default_issue_tracker.to_param
end
x.report("") do
'gitlab'
end
x.compare!
end
Calculating -------------------------------------
current 4.000 i/100ms
30.938k i/100ms
-------------------------------------------------
current 47.298 (±10.6%) i/s - 232.000
4.366M (±20.9%) i/s - 17.202M
Comparison:
: 4366456.0 i/s
current: 47.3 i/s - 92318.26x slower

Improve validations and error handling in new CI config entries
## What does this MR do?
This MR improves validation in new CI config.
## Why was this MR needed?
With that it will be easier to handle errors during validation and post-processing.
## What are the relevant issue numbers?
This is a continuation of #15060
See merge request !4560
We assume that when someone adds a key for the configuration entry, but
does not provide a valid value, which causes entry to be `nil`, then
entry should be considered as the undefined one. We also assume this is
semantically correct, this is also backwards compatible with legacy CI
config processor.
See issue #18775 for more details.
Fix subsequent SAML sign ins
Fixes a bug when `auto_link_ldap_user` is `true` that causes SAML users to be unable to sign in a second time.
Fix the problem for https://gitlab.zendesk.com/agent/tickets/22546
See merge request !4718
Resolve "Destroying a project causes post_decline_request to be executed"
## What does this MR do?
Ensure we don't send "access request declined" to access requesters when a project is deleted.
## Are there points in the code the reviewer needs to double check?
I've created a service to decouple the notification sending from the AR model.
## Why was this MR needed?
Because there was an issue.
