* Added log-file flag to capture Consul logs in a user specified file
* Refactored code.
* Refactored code. Added flags to rotate logs based on bytes and duration
* Added the flags for log file and log rotation on the webpage
* Fixed TestSantize from failing due to the addition of 3 flags
* Introduced changes : mutex, data-dir log writes, rotation logic
* Added test for logfile and updated the default log destination for docs
* Log name now uses UnixNano
* TestLogFile is now uses t.Parallel()
* Removed unnecessary int64Val function
* Updated docs to reflect default log name for log-file
* No longer writes to data-dir and adds .log if the filename has no extension
* Move notification texts to a slightly different layer (#4572)
* Further Simplify/refactor the actions/notification layer (#4573)
1. Move the 'with-feedback' actions to a 'with-blocking-action' mixin
which better describes what it does
2. Additional set of unit tests almost over the entire layer to prove
things work/add confidence for further changes
The multiple 'with-action' mixins used for every 'index/edit' combo are
now reduced down to only contain the functionality related to their
specific routes, i.e. where to redirect.
The actual functionality to block and carry out the action and then
notify are 'almost' split out so that their respective classes/objects do
one thing and one thing 'well'.
Mixins are chosen for the moment as the decoration approach used by
mixins feels better than multiple levels of inheritence, but I would
like to take this fuether in the future to a 'compositional' based
approach.
There is still possible further work to be done here, but I'm a lot
happier now this is reduced down into separate parts.
* Begin refactoring CSS into component folders. Moved most
components into layout/skin folders, left out a couple of ones I want
to think about more.
* Adjust grays based on recent Structure changes
* Switch to fullscreen layout for lists and detail, left aligned forms (#4435)
* Specifically use the 'actions_close' label, not just the :last-child (actions-group)
* Replace some non-var-ed colours in vaults code skin, plus prefixing (black and white)
ui: Repo layer integration tests for methods that touch the API
Includes a `repo` test helper to make repetitive tasks easier, plus a
injectable reporter for sending performance metrics to a centralized metrics
system
Also noticed somewhere in the ember models that I'd like to improve, but left
for the moment to make sure I concentrate on one task at a time, more or less:
The tests currently asserts against the existing JSON tree, which doesn't
seem to be a very nice tree.
The work at hand here is to refactor what is there, so test for the not
nice tree to ensure we don't get any regression, and add a skipped test
so I can come back here later
WIP Unskip some lower level trivial tests.
This is the beginning of work to unskip some of the more trivial tests that I'd skipped a while back (if the thing they are testing broke, they would have failed higher up in other acceptance tests).
I'd rather keep the tests, as they do test things in a more isolated manner, and the plan was to always come back and work to unskip them time allowing.
I didn't get to far into this work in progress here, but I'd rather merge what I've done all the same and come back at a later date and continue.
By default, the Consul agent listens on the local interface
at port 8500 for API requests. This change makes the API examples
using `curl` copy-pasteable for this default configuration.
1. Split the resizing functionality of into a separate mixin to be
shared across components
2. Add basic integration tests to prove that everything is getting
called through out the lifetime of the app. I decided against unit
testing as there isn't really any isolated logic to be tested, more
checking that things are being called in the correct order etc i.e. the
integration is correct.
Adds assertion to with-resizing so its obvious to override `resize`
Fixes#4515
This just slightly refactors the logic to only attempt to set the serf wan reconnect timeout when the rest of the serf wan settings are configured - thus avoiding a segfault.
* Display more information about check being not properly added when it fails
It follows an incident where we add lots of error messages:
[WARN] consul.fsm: EnsureRegistration failed: failed inserting check: Missing service registration
That seems related to Consul failing to restart on respective agents.
Having Node information as well as service information would help diagnose the issue.
* Renamed ensureCheckIfNodeMatches() as requested by @banks
- Add WaitForTestAgent to tests flaky due to missing serfHealth registration
- Fix bug in retries calling Fatalf with *testing.T
- Convert TestLockCommand_ChildExitCode to table driven test
* Allow to rename nodes with IDs, will fix#3974 and #4413
This change allow to rename any well behaving recent agent with an
ID to be renamed safely, ie: without taking the name of another one
with case insensitive comparison.
Deprecated behaviour warning
----------------------------
Due to asceding compatibility, it is still possible however to
"take" the name of another name by not providing any ID.
Note that when not providing any ID, it is possible to have 2 nodes
having similar names with case differences, ie: myNode and mynode
which might lead to DB corruption on Consul server side and
lead to server not properly restarting.
See #3983 and #4399 for Context about this change.
Disabling registration of nodes without IDs as specified in #4414
should probably be the way to go eventually.
* Removed the case-insensitive search when adding a node within the else
block since it breaks the test TestAgentAntiEntropy_Services
While the else case is probably legit, it will be fixed with #4414 in
a later release.
* Added again the test in the else to avoid duplicated names, but
enforce this test only for nodes having IDs.
Thus most tests without any ID will work, and allows us fixing
* Added more tests regarding request with/without IDs.
`TestStateStore_EnsureNode` now test registration and renaming with IDs
`TestStateStore_EnsureNodeDeprecated` tests registration without IDs
and tests removing an ID from a node as well as updated a node
without its ID (deprecated behaviour kept for backwards compatibility)
* Do not allow renaming in case of conflict, including when other node has no ID
* Fixed function GetNodeID that was not working due to wrong type when searching node from its ID
Thus, all tests about renaming were not working properly.
Added the full test cas that allowed me to detect it.
* Better error messages, more tests when nodeID is not a valid UUID in GetNodeID()
* Added separate TestStateStore_GetNodeID to test GetNodeID.
More complete test coverage for GetNodeID
* Added new unit test `TestStateStore_ensureNoNodeWithSimilarNameTxn`
Also fixed comments to be clearer after remarks from @banks
* Fixed error message in unit test to match test case
* Use uuid.ParseUUID to parse Node.ID as requested by @mkeeler
This includes fixes that improve gossip scalability on very large (> 10k node) clusters.
The Serf changes:
- take snapshot disk IO out of the critical path for handling messages hashicorp/serf#524
- make snapshot compaction much less aggressive - the old fixed threshold caused snapshots to be constantly compacted (synchronously with request handling) on clusters larger than about 2000 nodes! hashicorp/serf#525
Memberlist changes:
- prioritize handling alive messages over suspect/dead to improve stability, and handle queue in LIFO order to avoid acting on info that 's already stale in the queue by the time we handle it. hashicorp/memberlist#159
- limit the number of concurrent pushPull requests being handled at once to 128. In one test scenario with 10s of thousands of servers we saw channel and lock blocking cause over 3000 pushPulls at once which ballooned the memory of the server because each push pull contained a de-serialised list of all known 10k+ nodes and their tags for a total of about 60 million objects and 7GB of memory stuck. While the rest of the fixes here should prevent the same root cause from blocking in the same way, this prevents any other bug or source of contention from allowing pushPull messages to stack up and eat resources. hashicorp/memberlist#158
