+2. License Grants and Conditions
+
+2.1. Grants
+
+ Each Contributor hereby grants You a world-wide, royalty-free,
+ non-exclusive license:
+
+ a. under intellectual property rights (other than patent or trademark)
+ Licensable by such Contributor to use, reproduce, make available,
+ modify, display, perform, distribute, and otherwise exploit its
+ Contributions, either on an unmodified basis, with Modifications, or
+ as part of a Larger Work; and
+
+ b. under Patent Claims of such Contributor to make, use, sell, offer for
+ sale, have made, import, and otherwise transfer either its
+ Contributions or its Contributor Version.
+
+2.2. Effective Date
+
+ The licenses granted in Section 2.1 with respect to any Contribution
+ become effective for each Contribution on the date the Contributor first
+ distributes such Contribution.
+
+2.3. Limitations on Grant Scope
+
+ The licenses granted in this Section 2 are the only rights granted under
+ this License. No additional rights or licenses will be implied from the
+ distribution or licensing of Covered Software under this License.
+ Notwithstanding Section 2.1(b) above, no patent license is granted by a
+ Contributor:
+
+ a. for any code that a Contributor has removed from Covered Software; or
+
+ b. for infringements caused by: (i) Your and any other third party's
+ modifications of Covered Software, or (ii) the combination of its
+ Contributions with other software (except as part of its Contributor
+ Version); or
+
+ c. under Patent Claims infringed by Covered Software in the absence of
+ its Contributions.
+
+ This License does not grant any rights in the trademarks, service marks,
+ or logos of any Contributor (except as may be necessary to comply with
+ the notice requirements in Section 3.4).
+
+2.4. Subsequent Licenses
+
+ No Contributor makes additional grants as a result of Your choice to
+ distribute the Covered Software under a subsequent version of this
+ License (see Section 10.2) or under the terms of a Secondary License (if
+ permitted under the terms of Section 3.3).
+
+2.5. Representation
+
+ Each Contributor represents that the Contributor believes its
+ Contributions are its original creation(s) or it has sufficient rights to
+ grant the rights to its Contributions conveyed by this License.
+
+2.6. Fair Use
+
+ This License is not intended to limit any rights You have under
+ applicable copyright doctrines of fair use, fair dealing, or other
+ equivalents.
+
+2.7. Conditions
+
+ Sections 3.1, 3.2, 3.3, and 3.4 are conditions of the licenses granted in
+ Section 2.1.
+
+
+3. Responsibilities
+
+3.1. Distribution of Source Form
+
+ All distribution of Covered Software in Source Code Form, including any
+ Modifications that You create or to which You contribute, must be under
+ the terms of this License. You must inform recipients that the Source
+ Code Form of the Covered Software is governed by the terms of this
+ License, and how they can obtain a copy of this License. You may not
+ attempt to alter or restrict the recipients' rights in the Source Code
+ Form.
+
+3.2. Distribution of Executable Form
+
+ If You distribute Covered Software in Executable Form then:
+
+ a. such Covered Software must also be made available in Source Code Form,
+ as described in Section 3.1, and You must inform recipients of the
+ Executable Form how they can obtain a copy of such Source Code Form by
+ reasonable means in a timely manner, at a charge no more than the cost
+ of distribution to the recipient; and
+
+ b. You may distribute such Executable Form under the terms of this
+ License, or sublicense it under different terms, provided that the
+ license for the Executable Form does not attempt to limit or alter the
+ recipients' rights in the Source Code Form under this License.
+
+3.3. Distribution of a Larger Work
+
+ You may create and distribute a Larger Work under terms of Your choice,
+ provided that You also comply with the requirements of this License for
+ the Covered Software. If the Larger Work is a combination of Covered
+ Software with a work governed by one or more Secondary Licenses, and the
+ Covered Software is not Incompatible With Secondary Licenses, this
+ License permits You to additionally distribute such Covered Software
+ under the terms of such Secondary License(s), so that the recipient of
+ the Larger Work may, at their option, further distribute the Covered
+ Software under the terms of either this License or such Secondary
+ License(s).
+
+3.4. Notices
+
+ You may not remove or alter the substance of any license notices
+ (including copyright notices, patent notices, disclaimers of warranty, or
+ limitations of liability) contained within the Source Code Form of the
+ Covered Software, except that You may alter any license notices to the
+ extent required to remedy known factual inaccuracies.
+
+3.5. Application of Additional Terms
+
+ You may choose to offer, and to charge a fee for, warranty, support,
+ indemnity or liability obligations to one or more recipients of Covered
+ Software. However, You may do so only on Your own behalf, and not on
+ behalf of any Contributor. You must make it absolutely clear that any
+ such warranty, support, indemnity, or liability obligation is offered by
+ You alone, and You hereby agree to indemnify every Contributor for any
+ liability incurred by such Contributor as a result of warranty, support,
+ indemnity or liability terms You offer. You may include additional
+ disclaimers of warranty and limitations of liability specific to any
+ jurisdiction.
+
+4. Inability to Comply Due to Statute or Regulation
+
+ If it is impossible for You to comply with any of the terms of this License
+ with respect to some or all of the Covered Software due to statute,
+ judicial order, or regulation then You must: (a) comply with the terms of
+ this License to the maximum extent possible; and (b) describe the
+ limitations and the code they affect. Such description must be placed in a
+ text file included with all distributions of the Covered Software under
+ this License. Except to the extent prohibited by statute or regulation,
+ such description must be sufficiently detailed for a recipient of ordinary
+ skill to be able to understand it.
+
+5. Termination
+
+5.1. The rights granted under this License will terminate automatically if You
+ fail to comply with any of its terms. However, if You become compliant,
+ then the rights granted under this License from a particular Contributor
+ are reinstated (a) provisionally, unless and until such Contributor
+ explicitly and finally terminates Your grants, and (b) on an ongoing
+ basis, if such Contributor fails to notify You of the non-compliance by
+ some reasonable means prior to 60 days after You have come back into
+ compliance. Moreover, Your grants from a particular Contributor are
+ reinstated on an ongoing basis if such Contributor notifies You of the
+ non-compliance by some reasonable means, this is the first time You have
+ received notice of non-compliance with this License from such
+ Contributor, and You become compliant prior to 30 days after Your receipt
+ of the notice.
+
+5.2. If You initiate litigation against any entity by asserting a patent
+ infringement claim (excluding declaratory judgment actions,
+ counter-claims, and cross-claims) alleging that a Contributor Version
+ directly or indirectly infringes any patent, then the rights granted to
+ You by any and all Contributors for the Covered Software under Section
+ 2.1 of this License shall terminate.
+
+5.3. In the event of termination under Sections 5.1 or 5.2 above, all end user
+ license agreements (excluding distributors and resellers) which have been
+ validly granted by You or Your distributors under this License prior to
+ termination shall survive termination.
+
+6. Disclaimer of Warranty
+
+ Covered Software is provided under this License on an "as is" basis,
+ without warranty of any kind, either expressed, implied, or statutory,
+ including, without limitation, warranties that the Covered Software is free
+ of defects, merchantable, fit for a particular purpose or non-infringing.
+ The entire risk as to the quality and performance of the Covered Software
+ is with You. Should any Covered Software prove defective in any respect,
+ You (not any Contributor) assume the cost of any necessary servicing,
+ repair, or correction. This disclaimer of warranty constitutes an essential
+ part of this License. No use of any Covered Software is authorized under
+ this License except under this disclaimer.
+
+7. Limitation of Liability
+
+ Under no circumstances and under no legal theory, whether tort (including
+ negligence), contract, or otherwise, shall any Contributor, or anyone who
+ distributes Covered Software as permitted above, be liable to You for any
+ direct, indirect, special, incidental, or consequential damages of any
+ character including, without limitation, damages for lost profits, loss of
+ goodwill, work stoppage, computer failure or malfunction, or any and all
+ other commercial damages or losses, even if such party shall have been
+ informed of the possibility of such damages. This limitation of liability
+ shall not apply to liability for death or personal injury resulting from
+ such party's negligence to the extent applicable law prohibits such
+ limitation. Some jurisdictions do not allow the exclusion or limitation of
+ incidental or consequential damages, so this exclusion and limitation may
+ not apply to You.
+
+8. Litigation
+
+ Any litigation relating to this License may be brought only in the courts
+ of a jurisdiction where the defendant maintains its principal place of
+ business and such litigation shall be governed by laws of that
+ jurisdiction, without reference to its conflict-of-law provisions. Nothing
+ in this Section shall prevent a party's ability to bring cross-claims or
+ counter-claims.
+
+9. Miscellaneous
+
+ This License represents the complete agreement concerning the subject
+ matter hereof. If any provision of this License is held to be
+ unenforceable, such provision shall be reformed only to the extent
+ necessary to make it enforceable. Any law or regulation which provides that
+ the language of a contract shall be construed against the drafter shall not
+ be used to construe this License against a Contributor.
+
+
+10. Versions of the License
+
+10.1. New Versions
+
+ Mozilla Foundation is the license steward. Except as provided in Section
+ 10.3, no one other than the license steward has the right to modify or
+ publish new versions of this License. Each version will be given a
+ distinguishing version number.
+
+10.2. Effect of New Versions
+
+ You may distribute the Covered Software under the terms of the version
+ of the License under which You originally received the Covered Software,
+ or under the terms of any subsequent version published by the license
+ steward.
+
+10.3. Modified Versions
+
+ If you create software not governed by this License, and you want to

+golang-lru
+==========
+
+This provides the `lru` package which implements a fixed-size
+thread safe LRU cache. It is based on the cache in Groupcache.
+
+Documentation
+=============
+
+Full docs are available on [Go Packages](https://pkg.go.dev/github.com/hashicorp/golang-lru/v2)
+
+LRU cache example
+=================
+
+```go
+package main
+
+import (
+ "fmt"
+ "github.com/hashicorp/golang-lru/v2"
+)
+
+func main() {
+ l, _ := lru.New[int, any](128)
+ for i := 0; i < 256; i++ {
+ l.Add(i, nil)
+ }
+ if l.Len() != 128 {
+ panic(fmt.Sprintf("bad len: %v", l.Len()))
+ }
+}
+```
+
+Expirable LRU cache example
+===========================
+
+```go
+package main
+
+import (
+ "fmt"
+ "time"
+
+ "github.com/hashicorp/golang-lru/v2/expirable"
+)
+
+func main() {
+ // make cache with 10ms TTL and 5 max keys
+ cache := expirable.NewLRU[string, string](5, nil, time.Millisecond*10)
+
+
+ // set value under key1.
+ cache.Add("key1", "val1")
+
+ // get value under key1
+ r, ok := cache.Get("key1")
+
+ // check for OK value
+ if ok {
+ fmt.Printf("value before expiration is found: %v, value: %q\n", ok, r)
+ }
+
+ // wait for cache to expire
+ time.Sleep(time.Millisecond * 12)
+
+ // get value under key1 after key expiration
+ r, ok = cache.Get("key1")
+ fmt.Printf("value after expiration is found: %v, value: %q\n", ok, r)
+
+ // set value under key2, would evict old entry because it is already expired.
+ cache.Add("key2", "val2")
+
+ fmt.Printf("Cache len: %d\n", cache.Len())
+ // Output:
+ // value before expiration is found: true, value: "val1"
+ // value after expiration is found: false, value: ""
+ // Cache len: 1
+}
+```

+// Package lru provides three different LRU caches of varying sophistication.
+//
+// Cache is a simple LRU cache. It is based on the LRU implementation in
+// groupcache: https://github.com/golang/groupcache/tree/master/lru
+//
+// TwoQueueCache tracks frequently used and recently used entries separately.
+// This avoids a burst of accesses from taking out frequently used entries, at
+// the cost of about 2x computational overhead and some extra bookkeeping.
+//
+// ARCCache is an adaptive replacement cache. It tracks recent evictions as well
+// as recent usage in both the frequent and recent caches. Its computational
+// overhead is comparable to TwoQueueCache, but the memory overhead is linear
+// with the size of the cache.
+//
+// ARC has been patented by IBM, so do not use it if that is problematic for
+// your program. For this reason, it is in a separate go module contained within
+// this repository.
+//
+// All caches in this package take locks while operating, and are therefore
+// thread-safe for consumers.
