Subject [jira] [Resolved] (INFRA-10765) Conditional download of files from ASF Git repos
Date Tue, 01 Mar 2016 11:24:18 GMT

Daniel Gruno resolved INFRA-10765.
----------------------------------
    Resolution: Later
      Assignee: Daniel Gruno

This is not something we can fix ourselves at present time, as that is served from GitWeb.
I am marking this as 'Later', as we may eventually find a fix for it.

> It's possible to download individual files from Git, for example:
> https://git-wip-us.apache.org/repos/asf?p=infrastructure-puppet.git;a=blob_plain;f=Puppetfile;hb=HEAD
> This returns the file contents, however the headers give no indication of the date/version/hash
of the file:
> --- cut here ---
> Date: Sat, 14 Nov 2015 12:17:51 GMT
> Server: Apache/2.4.7 (Ubuntu)
> Content-Disposition: inline; filename="Puppetfile"
> Vary: Accept-Encoding
> Content-Encoding: gzip
> Content-Length: 1104
> Keep-Alive: timeout=30, max=99
> Connection: Keep-Alive
> Content-Type: text/plain; charset=ISO-8859-1
> 200 OK
> --- cut here ---
> This means that it is not possible to make a conditional HTTP GET request for the file.
> This may not matter for a short file, but for a large file it creates unnecessary traffic
and takes longer than necessary.
> The same file is available from GitHub:
> https://raw.githubusercontent.com/apache/infrastructure-puppet/deployment/Puppetfile
> This returns the following headers (most elided):
> --- cut here ---
> Etag: "c8ab7a99c6cef0ca6b2759b8b39301a6e85cb932"
> Content-Type: text/plain; charset=utf-8
> Content-Encoding: gzip
> Content-Length: 1104
> --- cut here ---
> The Etag means that a conditional HTTP GET request can be used.
> Is there any reason why the canonical ASF Git repos do not support Etag or Last-Modified
headers?
