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. |
||||

||||
obtain one at |
||||

|
||||
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. |
||||
|
||||

||||
|
||||

# go-reap |
||||
|
||||
Provides a super simple set of functions for reaping child processes. This is |
||||
useful for running applications as PID 1 in a Docker container. |
||||
|
||||
Note that a mutex is supplied to allow your application to prevent reaping of |
||||
child processes during certain periods. You need to use care in order to |
||||
prevent the reaper from stealing your return values from uses of packages like |
||||
Go's exec. We use an `RWMutex` so that we don't serialize all of your |
||||
application's execution of sub processes with each other, but we do serialize |
||||
them with reaping. Your application should get a read lock when it wants to do |
||||
a wait and be safe from the reaper. |
||||
|
||||
This should be supported on most UNIX flavors, but is not supported on Windows |
||||
or Solaris. Unsupported platforms have a stub implementation that's safe to call, |
||||
as well as an API to check if reaping is supported so that you can produce an |
||||
error in your application code. |
||||

||||
