| * Match the OOM beahvior of 1.8.5Paul J. Davis2020-01-064-0/+55
| | | | | | | | | | | | Apparently SpiderMonkey 60 changed the behavior of OOM errors to not exit the VM. This updates the SpiderMonkey 60 implementation to match that behavior.
| * Remove allowance for unnamed_errorPaul J. Davis2020-01-061-1/+1
| | | | | | | | | | This test is actually checking the behvior of an OOM in `couchjs` now since we lifted the OS process timeout limit.
| * Set `couchTests.elixir = true` to skip ported testsPaul J. Davis2020-01-064-4/+4
| | | | | | | | | | | | This avoids the 1.2s pause between tests to save time during the test suite. All ported tests are also logged to measure our progress porting the JS test suite.

| | | | | | | | | | | | | | | The hqueue dependency is only needed for experimental IOQ2 functionality that is not included in the codebase we're bringing into the mainline.

| | * Enable users to bypass IOQ for certain IO classesAdam Kocoloski2020-01-061-9/+40
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch allows an administrator to configure a "bypass" which will cause a particular class of IO to be submitted directly to the file descriptor or OS process instead of going through the IO queueing mechanism. Installing a bypass can result in higher throughput and lower latency, at the expense of less control over the stability of the system. A bypass is configured via the `ioq.priority` configuration block: [ioq.bypass] read = true write = true compaction = false This configuration will cause user-submitted read IO to be submitted directly. At this time the following classes are available: - os_process - read - write - view_update - shard_sync - compaction This also expands the "compaction" queue to be a general-purpose "background" queue that handles IO for both compaction and internal replication (aka shard_sync). The other four classes are handled by the "interactive" queue. As before, the [ioq] ratio setting determines the likelihood that background IO will be selected ahead of interactive IO when both queues are non-empty.

| | | | | | Closes #1567
| * Set a high priority on couch_serverPaul J. Davis2020-01-053-0/+17
| | | | | | | | | | | | | | | | | | | | In a VM with lots of processes couch_server can end up slowing down purely to not being scheduled which in turn will cause its message queue to backup. We've attempted this before but due to message passing have never seen it have a significant effect. However, now that we're actively avoiding synchronous message passing inside the man loop this has a significant effect by being able to process messages as soon as it has one in its mailbox.
| * Move more work out of couch_server's main loopPaul J. Davis2020-01-051-59/+92
| | | | | | | | | | | | | | This moves the database name check and engine lookup into the open_async process. There's no reason that this work had to happen in the main loop so we can easily move the regex and engine lookups out of the loop to minimize the work per handle_call even further.
| * Track db open times in the async_open pidPaul J. Davis2020-01-051-14/+19
| | | | | | | | | | We can track the open latencies from the async_open process so that couch_server does not have to perform the update in its main loop.
| * Reduce logging calls in couch_serverPaul J. Davis2020-01-051-4/+15
| | | | | | | | | | Even when disabled these logs can take a non-trivial amount of reductions which can add extra suspensions to couch_server's main loop.
| * Avoid file_server_2 for existance testsPaul J. Davis2020-01-051-2/+11
| | | | | | | | | | Its not uncommon to have file_server_2 behaving poorly so we'll avoid it when there are calls that are made often.
| * Simplfiy interleaved message couch_server testPaul J. Davis2020-01-051-33/+17
| | | | | | | | | | | | | | Previous this test relied on delete/open requests getting things into a confused state. Now that we understand the issue we can replace the more complicated logic by directly polutnig couch_server's message queue with invalid messages.

| * Lock shard splitting targets during the initial copy phaseNick Vatamaniuc2020-01-055-8/+141
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | During the initial copy phase target shards are opened outside the couch_server. Previously, it was possible to manually (via remsh for instance) open the same targets via the couch_server by using the `couch_db:open/2` API for example. That could lead to corruption as there would be two writers for the same DB file. In order to prevent such a scenario, introduce a mechanism for the shard splitter to lock the target shards such that any regular open call would fail during the initial copy phase. The locking mechanism is generic and would allow local locking of shards for possibly other reasons in the future as well.
