1) Set metadata "Content-Encoding" automatically(Issue 292)
For this issue, s3fs is added new option "ahbe_conf".
New option means the configuration file path, and this file specifies
additional HTTP header by file(object) extension.
Thus you can specify any HTTP header for each object by extension.
* ahbe_conf file format:
-----------
line = [file suffix] HTTP-header [HTTP-header-values]
file suffix = file(object) suffix, if this field is empty,
it means "*"(all object).
HTTP-header = additional HTTP header name
HTTP-header-values = additional HTTP header value
-----------
* Example:
-----------
.gz Content-Encoding gzip
.Z Content-Encoding compress
X-S3FS-MYHTTPHEAD myvalue
-----------
A sample configuration file is uploaded in "test" directory.
If ahbe_conf parameter is specified, s3fs loads it's configuration
and compares extension(suffix) of object(file) when uploading
(PUT/POST) it. If the extension is same, s3fs adds/sends specified
HTTP header and value.
A case of sample configuration file, if a object(it's extension is
".gz") which already has Content-Encoding HTTP header is renamed
to ".txt" extension, s3fs does not set Content-Encoding. Because
".txt" is not match any line in configuration file.
So, s3fs matches the extension by each PUT/POST action.
* Please take care about "Content-Encoding".
This new option allows setting ANY HTTP header by object extension.
For example, you can specify "Content-Encoding" for ".gz"/etc
extension in configuration. But this means that S3 always returns
"Content-Encoding: gzip" when a client requests with other
"Accept-Encoding:" header. It SHOULD NOT be good.
Please see RFC 2616.
2) Changes about allow_other/uid/gid option for mount point
I reviewed about mount point permission and allow_other/uid/gid
options, and found bugs about these.
s3fs is fixed bugs and changed to the following specifications.
* s3fs only allows uid(gid) options as 0(root), when the effective
user is zero(root).
* A mount point(directory) must have a permission to allow
accessing by effective user/group.
* If allow_other option is specified, the mount point permission
is set 0777(all users allow all access).
In another case, the mount point is set 0700(only allows
effective user).
* When uid/gid option is specified, the mount point owner/group
is set uid/gid option value.
If uid/gid is not set, it is set effective user/group id.
This changes maybe fixes some issue(321, 338).
3) Changes a logic about (Issue 229)
The chmod command returns -EIO when changing the mount point.
It is correct, s3fs can not changed owner/group/mtime for the
mount point, but s3fs sends a request for changing the bucket.
This revision does not send the request, and returns EIO as
soon as possible.

# S3FS: Samlpe ahbe_conf parameter file.
|
|
#
|
|
# This file is configuration file for additional header by extension(ahbe).
|
|
# s3fs loads this file at starting.
|
|
#
|
|
# Format:
|
|
# line = [file suffix] HTTP-header [HTTP-header-values]
|
|
# file suffix = file(object) suffix, if this field is empty,
|
|
# it means "*"(all object).
|
|
# HTTP-header = additional HTTP header name
|
|
# HTTP-header-values = additional HTTP header value
|
|
#
|
|
# <suffix(extension)> <HTTP header> <HTTP header values>
|
|
#
|
|
# Example:
|
|
# " Content-Encoding gzip" --> all object
|
|
# ".gz Content-Encoding gzip" --> only ".gz" extension file
|
|
#
|
|
# Notice:
|
|
# If you need to set all object, you can specify without "suffix".
|
|
# Then all of object(file) is added additional header.
|
|
# If you have this configuration file for Content-Encoding, you should
|
|
# know about RFC 2616.

# "The default (identity) encoding; the use of no transformation
