||||
* StatsiteSink : Sinks to a [statsite](https://github.com/armon/statsite/) instance (TCP)
|
||||
* StatsdSink: Sinks to a [StatsD](https://github.com/etsy/statsd/) / statsite instance (UDP)
|
||||
* PrometheusSink: Sinks to a [Prometheus](http://prometheus.io/) metrics endpoint (exposed via HTTP for scrapes)
|
||||
* InmemSink : Provides in-memory aggregation, can be used to export stats
|
||||
* FanoutSink : Sinks to multiple sinks. Enables writing to multiple statsite instances for example.
|
||||
* BlackholeSink : Sinks to nowhere
|
||||
|
||||
In addition to the sinks, the `InmemSignal` can be used to catch a signal,
|
||||
and dump a formatted output of recent metrics. For example, when a process gets
|
||||
a SIGUSR1, it can dump to stderr recent performance metrics for debugging.
|
||||
|
||||
Labels
|
||||
------
|
||||
|
||||
Most metrics do have an equivalent ending with `WithLabels`, such methods
|
||||
allow to push metrics with labels and use some features of underlying Sinks
|
||||
(ex: translated into Prometheus labels).
|
||||
|
||||
Since some of these labels may increase greatly cardinality of metrics, the
|
||||
library allow to filter labels using a blacklist/whitelist filtering system
|
||||
which is global to all metrics.
|
||||
|
||||
* If `Config.AllowedLabels` is not nil, then only labels specified in this value will be sent to underlying Sink, otherwise, all labels are sent by default.
|
||||
* If `Config.BlockedLabels` is not nil, any label specified in this value will not be sent to underlying Sinks.
|
||||
|
||||
By default, both `Config.AllowedLabels` and `Config.BlockedLabels` are nil, meaning that
|
||||
no tags are filetered at all, but it allow to a user to globally block some tags with high
|
||||
cardinality at application level.
|
||||
|
||||
Examples
|
||||
--------
|
||||
|
||||
Here is an example of using the package:
|
||||
|
||||
```go
|
||||
func SlowMethod() {
|
||||
// Profiling the runtime of a method
|
||||
defer metrics.MeasureSince([]string{"SlowMethod"}, time.Now())
|
||||
}
|
||||
|
||||
// Configure a statsite sink as the global metrics sink
|
||||
sink, _ := metrics.NewStatsiteSink("statsite:8125")
|
||||
metrics.NewGlobal(metrics.DefaultConfig("service-name"), sink)
|
||||
|
||||
// Emit a Key/Value pair
|
||||
metrics.EmitKey([]string{"questions", "meaning of life"}, 42)
|
||||
```
|
||||
|
||||
Here is an example of setting up a signal handler:
|
||||
|
||||
```go
|
||||
// Setup the inmem sink and signal handler
|
||||
inm := metrics.NewInmemSink(10*time.Second, time.Minute)
|
||||
sig := metrics.DefaultInmemSignal(inm)
|
||||
metrics.NewGlobal(metrics.DefaultConfig("service-name"), inm)
|
||||
|
||||
// Run some code
|
||||
inm.SetGauge([]string{"foo"}, 42)
|
||||
inm.EmitKey([]string{"bar"}, 30)
|
||||
|
||||
inm.IncrCounter([]string{"baz"}, 42)
|
||||
inm.IncrCounter([]string{"baz"}, 1)
|
||||
inm.IncrCounter([]string{"baz"}, 80)
|
||||
|
||||
inm.AddSample([]string{"method", "wow"}, 42)
|
||||
inm.AddSample([]string{"method", "wow"}, 100)
|
||||
inm.AddSample([]string{"method", "wow"}, 22)
|
||||
|
||||
....
|
||||
```
|
||||
|
||||
When a signal comes in, output like the following will be dumped to stderr:
|
||||
|
||||
[2014-01-28 14:57:33.04 -0800 PST][G] 'foo': 42.000
|
||||
[2014-01-28 14:57:33.04 -0800 PST][P] 'bar': 30.000
|
||||
[2014-01-28 14:57:33.04 -0800 PST][C] 'baz': Count: 3 Min: 1.000 Mean: 41.000 Max: 80.000 Stddev: 39.509
|
||||
[2014-01-28 14:57:33.04 -0800 PST][S] 'method.wow': Count: 3 Min: 22.000 Mean: 54.667 Max: 100.000 Stddev: 40.513

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
|
||||
create a new license for such software, you may create and use a
|
||||
modified version of this License if you rename the license and remove
|
||||
any references to the name of the license steward (except to note that
|
||||
such modified license differs from this License).
|
||||
|
||||
10.4. Distributing Source Code Form that is Incompatible With Secondary
|
||||
Licenses If You choose to distribute Source Code Form that is
|
||||
Incompatible With Secondary Licenses under the terms of this version of
|
||||
the License, the notice described in Exhibit B of this License must be
|
||||
attached.
|
||||
|
||||
Exhibit A - Source Code Form License Notice
|
||||
|
||||
This Source Code Form is subject to the
|
||||
terms of the Mozilla Public License, v.
|
||||
2.0. If a copy of the MPL was not
|
||||
distributed with this file, You can
|
||||
obtain one at
|
||||
http://mozilla.org/MPL/2.0/.
|
||||
|
||||
If it is not possible or desirable to put the notice in a particular file,
|
||||
then You may include the notice in a location (such as a LICENSE file in a
|
||||
relevant directory) where a recipient would be likely to look for such a
|
||||
notice.
|
||||
|
||||
You may add additional accurate notices of copyright ownership.
|
||||
|
||||
Exhibit B - "Incompatible With Secondary Licenses" Notice

go-immutable-radix [](https://circleci.com/gh/hashicorp/go-immutable-radix/tree/master)
|
||||
=========
|
||||
|
||||
Provides the `iradix` package that implements an immutable [radix tree](http://en.wikipedia.org/wiki/Radix_tree).
|
||||
The package only provides a single `Tree` implementation, optimized for sparse nodes.
|
||||
|
||||
As a radix tree, it provides the following:
|
||||
* O(k) operations. In many cases, this can be faster than a hash table since
|
||||
the hash function is an O(k) operation, and hash tables have very poor cache locality.
|
||||
* Minimum / Maximum value lookups
|
||||
* Ordered iteration
|
||||
|
||||
A tree supports using a transaction to batch multiple updates (insert, delete)
|
||||
in a more efficient manner than performing each operation one at a time.
|
||||
|
||||
For a mutable variant, see [go-radix](https://github.com/armon/go-radix).
|
||||
|
||||
Documentation
|
||||
=============
|
||||
|
||||
The full documentation is available on [Godoc](http://godoc.org/github.com/hashicorp/go-immutable-radix).
|
||||
|
||||
Example
|
||||
=======
|
||||
|
||||
Below is a simple example of usage
|
||||
|
||||
```go
|
||||
// Create a tree
|
||||
r := iradix.New()
|
||||
r, _, _ = r.Insert([]byte("foo"), 1)
|
||||
r, _, _ = r.Insert([]byte("bar"), 2)
|
||||
r, _, _ = r.Insert([]byte("foobar"), 2)
|
||||
|
||||
// Find the longest prefix match
|
||||
m, _, _ := r.Root().LongestPrefix([]byte("foozip"))
|
||||
if string(m) != "foo" {
|
||||
panic("should be foo")
|
||||
}
|
||||
```
|
||||
|
||||
Here is an example of performing a range scan of the keys.
|
||||
|
||||
```go
|
||||
// Create a tree
|
||||
r := iradix.New()
|
||||
r, _, _ = r.Insert([]byte("001"), 1)
|
||||
r, _, _ = r.Insert([]byte("002"), 2)
|
||||
r, _, _ = r.Insert([]byte("005"), 5)
|
||||
r, _, _ = r.Insert([]byte("010"), 10)
|
||||
r, _, _ = r.Insert([]byte("100"), 10)
|
||||
|
||||
// Range scan over the keys that sort lexicographically between [003, 050)
|
||||
it := r.Root().Iterator()
|
||||
it.SeekLowerBound([]byte("003"))
|
||||
for key, _, ok := it.Next(); ok; key, _, ok = it.Next() {
|
||||
if key >= "050" {
|
||||
break
|
||||
}
|
||||
fmt.Println(key)
|
||||
}
|
||||
// Output:
|
||||
// 005
|
||||
// 010
|
||||
```

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
|
||||
create a new license for such software, you may create and use a
|
||||
modified version of this License if you rename the license and remove
|
||||
any references to the name of the license steward (except to note that
|
||||
such modified license differs from this License).
|
||||
|
||||
10.4. Distributing Source Code Form that is Incompatible With Secondary
|
||||
Licenses If You choose to distribute Source Code Form that is
|
||||
Incompatible With Secondary Licenses under the terms of this version of
|
||||
the License, the notice described in Exhibit B of this License must be
|
||||
attached.
|
||||
|
||||

|
||||
|
||||
If it is not possible or desirable to put the notice in a particular file,
|
||||
then You may include the notice in a location (such as a LICENSE file in a
|
||||
relevant directory) where a recipient would be likely to look for such a
|
||||
notice.
|
||||
|
||||
You may add additional accurate notices of copyright ownership.
|
||||
|
||||
Exhibit B - "Incompatible With Secondary Licenses" Notice
