[PATCH v2 15/17] contrib: remove 'persistent-https'

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



No activity. No tests.

No chance of ever moving into the core because it uses Go.

-      or contributory patent infringement, then any patent licenses
-      granted to You under this License for that Work shall terminate
-      as of the date such litigation is filed.

-          the Derivative Works; and
-
-      (d) If the Work includes a "NOTICE" text file as part of its

-          pertain to any part of the Derivative Works, in at least one
-          of the following places: within a NOTICE text file distributed
-          as part of the Derivative Works; within the Source form or
-          documentation, if provided along with the Derivative Works; or,

-          notices within Derivative Works that You distribute, alongside
-          or as an addendum to the NOTICE text from the Work, provided
-          that such additional attribution notices cannot be construed
-          as modifying the License.
-
-      You may add Your own copyright statement to Your modifications and
-      may provide additional or different license terms and conditions
-      for use, reproduction, or distribution of Your modifications, or
-      for any such Derivative Works as a whole, provided Your use,
-      reproduction, and distribution of the Work otherwise complies with
-      the conditions stated in this License.
-
-   5. Submission of Contributions. Unless You explicitly state otherwise,
-      any Contribution intentionally submitted for inclusion in the Work
-      by You to the Licensor shall be under the terms and conditions of
-      this License, without any additional terms or conditions.
-      Notwithstanding the above, nothing herein shall supersede or modify

-      except as required for reasonable and customary use in describing the
-      origin of the Work and reproducing the content of the NOTICE file.

-      agreed to in writing, Licensor provides the Work (and each
-      Contributor provides its Contributions) on an "AS IS" BASIS,

-      PARTICULAR PURPOSE. You are solely responsible for determining the
-      appropriateness of using or redistributing the Work and assume any
-      risks associated with Your exercise of permissions under this License.
-
-   8. Limitation of Liability. In no event and under no legal theory,
-      whether in tort (including negligence), contract, or otherwise,
-      unless required by applicable law (such as deliberate and grossly
-      negligent acts) or agreed to in writing, shall any Contributor be
-      liable to You for damages, including any direct, indirect, special,
-      incidental, or consequential damages of any character arising as a
-      result of this License or out of the use or inability to use the
-      Work (including but not limited to damages for loss of goodwill,
-      work stoppage, computer failure or malfunction, or any and all
-      other commercial damages or losses), even if such Contributor
-      has been advised of the possibility of such damages.
-
-   9. Accepting Warranty or Additional Liability. While redistributing
-      the Work or Derivative Works thereof, You may choose to offer,
-      and charge a fee for, acceptance of support, warranty, indemnity,
-      or other liability obligations and/or rights consistent with this
-      License. However, in accepting such obligations, You may act only
-      on Your own behalf and on Your sole responsibility, not on behalf
-      of any other Contributor, and only if You agree to indemnify,
-      defend, and hold each Contributor harmless for any liability
-      incurred by, or claims asserted against, such Contributor by reason
-      of your accepting any such warranty or additional liability.

-git-remote-persistent-https
-
-The git-remote-persistent-https binary speeds up SSL operations
-by running a daemon job (git-remote-persistent-https--proxy) that
-keeps a connection open to a server.
-
-
-PRE-BUILT BINARIES
-
-Darwin amd64:
-https://commondatastorage.googleapis.com/git-remote-persistent-https/darwin_amd64.tar.gz
-
-Linux amd64:
-https://commondatastorage.googleapis.com/git-remote-persistent-https/linux_amd64.tar.gz
-
-
-INSTALLING
-
-Move all of the git-remote-persistent-http* binaries to a directory
-in PATH.
-
-
-USAGE
-
-HTTPS requests can be delegated to the proxy by using the
-"persistent-https" scheme, e.g.
-
-git clone persistent-https://kernel.googlesource.com/pub/scm/git/git
-
-Likewise, .gitconfig can be updated as follows to rewrite https urls
-to use persistent-https:
-
-[url "persistent-https"]
-	insteadof = https
-[url "persistent-http"]
-	insteadof = http
-
-
-#####################################################################
-# BUILDING FROM SOURCE
-#####################################################################
-
-LOCATION
-
-The source is available in the contrib/persistent-https directory of
-the Git source repository. The Git source repository is available at
-git://git.kernel.org/pub/scm/git/git.git/
-https://kernel.googlesource.com/pub/scm/git/git
-
-
-PREREQUISITES
-
-The code is written in Go (http://golang.org/) and the Go compiler is
-required. Currently, the compiler must be built and installed from tip
-of source, in order to include a fix in the reverse http proxy:
-http://code.google.com/p/go/source/detail?r=a615b796570a2cd8591884767a7d67ede74f6648
-
-
-BUILDING
-
-Run "make" to build the binaries. See the section on
-INSTALLING above.
