* Hand off the interlock to the new thread in AC::LiveMatthew Draper2016-02-071-23/+28
| | | | | | Most importantly, the original request thread must yield its share lock while waiting for the live thread to commit -- otherwise a request's base and live threads can deadlock against each other.
* disable controller / view thread spawning in testsAaron Patterson2016-02-051-2/+13
| | | | | | | | | | | | | | | | | | Tests can (and do) access the database from the main thread. In this case they were starting a transaction, then making a request. The request would create a new thread, which would allocate a new database connection. Since the main thread started a transaction that contains data that the new thread wants to see, the new thread would not see it due to data visibility from transactions. Spawning the new thread in production is fine because middleware should not be doing database manipulation similar to the test harness. Before 603fe20c it was possible to set the database connection id based on a thread local, but 603fe20c changes the connection lookup code to never look at the "connection id" but only at the thread object itself. Without that indirection, we can't force threads to use the same connection pool as another thread. Fixes #23483
* Fix `make_response!` when called by `serve` in `RouteSet`eileencodes2015-12-091-6/+1
| | | | | | | | | | | | | | | | | | | | | | | | | All of our tests were testing the `ActionController::Live` behavior in a standalone environment, without going through the router or behaving like a real application. This resulted in `ActionController::Live` throwing the exception `undefined method 'request' for #<ActionDispatch::Request:0x00000003ad1148>` because `make_response!` was expecting a response instead of a request. The expectation of a response came from `set_response!` in non-router tests setting the response and passing it to `make_response!`. In the case of an application we would hit `serve` in `RouteSet` first which would send us to `make_response!` with a request sent instead of a response. The changes here remove `set_response!` so `make_response!` always receives a request. Thanks to KalabiYau for help with the investigation and solution. Fixes #22524 [Eileen M. Uchitelle & KalabiYau]
* Push `before_sending` to super classeileencodes2015-12-061-6/+0
| | | | | | | | | | | | We want to get rid of the `Live::Response` so we are consolidating methods from `Live::Response` and `Response` by merging them together. This adds an `#empty` method to the request so we don't need to hard-code the empty array each time we call an empty `ActionDispatch::Request`. The work here is a continuation on combining controller and integration test code bases into one.
* use `dispatch` instead of `process` to run requests thougheileencodes2015-10-291-4/+5
| | | | | | | | | `dispatch` sets the request and response on the controller for us automatically, so the test harness doesn't need to know the internals of how request / response is set. Conflicts: actionpack/lib/action_controller/test_case.rb
* remove useless methodAaron Patterson2015-09-281-4/+0
| | | | | the caller of `handle_conditional_get!` checks the committed state of the response, so we don't need to in the subclass.
* move the Header hash to the super classAaron Patterson2015-09-241-27/+0
| | | | | | | I want to move the header hash to the super request object in order to consolidate behavior. We should be switching out buffering strategies rather than header strategies since things like "mutating headers after send" is an error in both cases (buffering vs streaming).
* stop applying default headers in ActionDispatch::ResponseAaron Patterson2015-09-231-4/+4
| | | | | | | | | | I'm making this change so that I can construct response objects that *don't* have the default headers applied. For example, I would like to construct a response object from the return value of a controller. If you need to construct a response object with the default headers, then please use the alternate constructor: `ActionDispatch::Response.create`
* use accessors instead of manipulating the hashAaron Patterson2015-09-081-2/+2
| | | | | in the future I would like to make the header hash read only (or at least remove guarantees that mutations will do anything).
* move response allocation to the class levelAaron Patterson2015-08-251-6/+15
| | | | | | we don't need an instance to figure out what type of response to allocate. Later we'll pull this up the stack and pass the response object down

* Prefer string patterns for gsubbrainopia2015-04-021-1/+1
| | | | | | | | | | | | | | | | | https://github.com/ruby/ruby/pull/579 - there is a new optimization since ruby 2.2 Previously regexp patterns were faster (since a string was converted to regexp underneath anyway). But now string patterns are faster and better reflect the purpose. Benchmark.ips do |bm| bm.report('regexp') { 'this is ::a random string'.gsub(/::/, '/') } bm.report('string') { 'this is ::a random string'.gsub('::', '/') } bm.compare! end # string: 753724.4 i/s # regexp: 501443.1 i/s - 1.50x slower
* remove unused #await_closeSergey Alekseev2014-12-041-6/+0
| | | | | | | | | The method was added in https://github.com/rails/rails/commit/30d21dfcb7fafe49b3805b8249454485a90097b6#diff-5055d9f16b442adb1d2f0f65903a196bR141. With the method call in https://github.com/rails/rails/commit/30d21dfcb7fafe49b3805b8249454485a90097b6#diff-cc7bb557df2247c0a42bc180fdb6eb05R47. Later one more method call was added in https://github.com/rails/rails/commit/401787db4bc428dce88b04e343a64c6a6c3b681c#diff-cc7bb557df2247c0a42bc180fdb6eb05R183. And both method calls were deleted in https://github.com/rails/rails/commit/3df07d093a1e4207caa63fd2e3b67599211f5800#diff-cc7bb557df2247c0a42bc180fdb6eb05L47 and https://github.com/rails/rails/commit/3df07d093a1e4207caa63fd2e3b67599211f5800#diff-cc7bb557df2247c0a42bc180fdb6eb05L189. Just do `grep -nr 'await_close' .`.

* just ask the response for the commit status, we do not need to ask the jarAaron Patterson2014-03-121-1/+1
|
* only write the jar if the response isn't committedAaron Patterson2014-03-121-4/+8
| | | | | | | | | | | when streaming responses, we need to make sure the cookie jar is written to the headers before returning up the stack. This commit introduces a new method on the response object that writes the cookie jar to the headers as the response is committed. The middleware and test framework will not write the cookie headers if the response has already been committed. fixes #14352
* use built-in exception handling in live controllersAaron Patterson2014-02-281-2/+5
| | | | | | when an exception happens in an action before the response has been committed, then we should re-raise the exception in the main thread. This lets us reuse the existing exception handling.
* live controllers should have live responsesAaron Patterson2014-02-281-2/+14
| | | | | | detect the type of controller we're testing and return the right type of response based on that controller. This allows us to stop doing the weird sleep thing.

* Correct prestreaming controller response status.Kevin Casey2014-02-151-0/+2
| | | | | | if the controller action has not yet streamed any data, actions should process as normal, and errors should trigger the appropriate behavior (500, or in the case of ActionController::BadRequest, a 400 Bad Request)

* Exception handling for controllers using ActionController::LiveSean Griffin2013-03-181-0/+28
| | | | | | | | | Any exceptions that occured at the view or controller level for a controller using ActionController::Live would cause the server to either hang with an open socket indefinitely, or immediately crash (depending on whether the server was launched with rails s or directly). Changed the behavior of exceptions to act the same as streaming templates for html requests, and allow for an on_error callback if needed.

| | | | | | | | | | responses. Processing controller actions in a separate thread allows us to work around the rack api - we can allow the user to set status and headers, then block until the first bytes are written. As soon as the first bytes are written, the main thread can return the status, headers, and (essentially) a queue for the body.
