* Fix ever increasing recent changes metricChristopher Baines2024-04-15
| | | | As processed recent changes were being counted as new.
* Don't block the removal-channel when running a full passChristopher Baines2024-04-15
|
* Store less in memory when scheduling the removal of cached narsChristopher Baines2024-04-05
|
* URI encode cached compression URLsChristopher Baines2024-04-04
|
* Add more logging around scheduled removal of cached compressionsChristopher Baines2024-04-02
|
* Add check for known hash when responding to /nar requestsChristopher Baines2024-04-01
|
* Raise level of some cached compression log messagesChristopher Baines2024-04-01
| | | | As I want to see these without lowering the log-level to DEBUG.
* Instrument the database and WAL file sizeChristopher Baines2024-04-01
|
* Track the number of cached nars scheduled for removalChristopher Baines2024-03-27
|

|
* Fix option nameChristopher Baines2024-03-26
|
* Remove left over peekChristopher Baines2024-03-26
|
* Fix argument nameChristopher Baines2024-03-25
|
* Add a fallback TTL for cached compression removalsChristopher Baines2024-03-25
|
* Improve handling of cached narinfos when deletingChristopher Baines2024-03-25
|
* Move all the database operations for cached nars to one fiberChristopher Baines2024-03-25
| | | | | | The management fiber. This adds the complexity of replying from the management fiber, but hopefully having all the database operations in one place makes things simpler.
* Instrument the number of cached compression filesChristopher Baines2024-03-25
|
* Rework the cached compressions systemChristopher Baines2024-03-25
| | | | | | | | | | | | | The initial implementation was flawed since guix assumes that any compression mentioned in the narinfo will be available for the lifetime of the narinfo, and the nar-herder was deleting cached compressions without taking this in to account. This commit adds support for scheduling the removal of a cached compression and this schedule is used to inform the TTLs for narinfos. I'm unsure of the value in caching narinfos so maybe some of this complexity can be removed in the future.
* Close the nar-port rather than the output-portChristopher Baines2024-03-23
| | | | | As we've finished reading from the nar-port, but the output-port represents the HTTP connection, and is still used.
* Update let styleChristopher Baines2024-03-23
|
* Fix scheduler variable nameChristopher Baines2024-03-23
|
* Remove with-fibers-timeoutChristopher Baines2024-03-23
| | | | As it's unused.
* Rename with-fibers-port-timeouts to with-port-timeoutsChristopher Baines2024-03-23
| | | | As it works with or without fibers.
* Tweak the server metricsChristopher Baines2024-03-22
| | | | | | Remove code in guile-prometheus, and use the new process collector. Also switch to using a non-namespaced registry for these non nar-herder specific collectors.
* Spawn cached compression fibers on the maintenance schedulerChristopher Baines2024-03-15
| | | | So they don't interact with the main scheduler.
* Add more TTL optionsChristopher Baines2024-03-15
| | | | | | I'm really not sure about this caching stuff, but these options should provide the flexibility to change the TTLs the nar-herder advertises gracefully.
* Update metrics while removing narsChristopher Baines2024-03-15
| | | | Rather than waiting until the end.
* Use cooperative fibers for maintenanceChristopher Baines2024-03-14
|
* Initialise the recent changes countChristopher Baines2024-03-14
|
* Stop updating the nar_files_total metric twiceChristopher Baines2024-03-14
|
* Instrument the recent changes countChristopher Baines2024-03-14
|
* Instrument the recent changes limitChristopher Baines2024-03-14
| | | | This doesn't change, but it's useful to have the value as a metric.
* Initialise the storage metricsChristopher Baines2024-03-13
| | | | This used to happen, and this commit brings it back.
* Have guild emit more warningsChristopher Baines2024-02-04
|
* Update .envrc to work with the newer direnvChristopher Baines2024-02-04
|
* Don't allow the mirror and removal channel to be unspecifiedChristopher Baines2023-11-23
| | | | As this is truthy.
* Move most functionality out of the start scriptChristopher Baines2023-09-12
| | | | As this can make debugging easier.
* Make with-fibers-port-timeouts work without fibersChristopher Baines2023-09-12
| | | | | As it's easy to try and use code in both contexts, so try and support that.
* Improve backtraces through call-with-cached-connectionChristopher Baines2023-09-12
|
* Update retry-on-error procedure from the Guix Build CoordinatorChristopher Baines2023-09-12
|
* Use recent changes to trigger the removal of narsChristopher Baines2023-09-12
| | | | | Both when the nar has been removed from the database, and to check if it should no longer be stored.
* Improve the metric handling furtherChristopher Baines2023-09-12
| | | | | This should avoid the metric being adjusted before it's been set initially.
* Remove get-nar-filesChristopher Baines2023-09-12
| | | | As it doesn't scale well.
* Use fold-nar-files for check-storageChristopher Baines2023-09-12
| | | | To avoid calling get-nar-files, as this doesn't scale well.
* Don't use JIT on aarch64Christopher Baines2023-09-12
| | | | | As there's bugs which cause parts of the program to execute more than once https://github.com/wingo/fibers/issues/83
* Add more logging around requesting recent changesChristopher Baines2023-09-12
|
* Cleanup handling of the nar_files_total metricChristopher Baines2023-09-12
|
* Remove the get-nar-files call from the fetch changes fiberChristopher Baines2023-09-12
| | | | As this is quite expensive.
* Log the procedure delayed for database operationsChristopher Baines2023-09-12
|
* Name the fibers threadsChristopher Baines2023-09-12
| | | | To help with debugging.
