When using an instance with an IAM Role, transient credentials can be
found in http://169.254.169.254/latest/meta-data/ at
iam/security-credentials/role-name and s3fs tries to do this. However,
it is using the profile-name where role-name is needed. In many cases
the role and profile name are the same, but they are not always.
The simplest way to find the role name appears to be to GET
http://169.254.169.254/latest/meta-data/iam/security-credentials/
itself, which returns a listing of the role names for which temporary
credentials exist. (I think there will probably only be one, but we
probably want to split on newlines and take the first one here in case
that assumption is not valid). This is the approach the AWS SDK appears
to use (based on WireShark analysis).

This allows retries of multi-part uploads instead of discovering a
fatal error during complete multipart upload. Also enable Content-MD5
for integration tests and refactor hexadecimal code.
Buckets with mixed-case names can't be accessed with the virtual-hosted
style API due to DNS limitations. S3FS has an option for
pathrequeststyle which is used for the URL, but it was not applied when
building the endpoint passed through the Host header. Fix this, and
relax the validation on bucket names when using this style.

Query parameters need a trailing = for V4 signatures. Send correct
content-sha256 although Amazon does not seem to enforce this for
zero-length bodies. Finally remove a stale comment. Fixes#133.
Subsequent commits will use this infrastructure. Also reparent
prepare_url which relies on unrelated bucket, foreground2, and
pathrequeststyle symbols.
The space causes signature mismatch when using "ahbe_conf" file to add additional headers.When s3 use the" x-amaz" header to calculates the signature, the format is as follow:
PUT
application/octet-stream
Wed, 05 Nov 2014 03:05:08 GMT
x-amz-acl:private
x-amz-meta-gid:0
x-amz-meta-mode:33188
x-amz-meta-mtime:1415156708
x-amz-meta-uid:0
There is no space after colon.
Previously S3fsMultiCurl::MultiRead did not report read errors since
it did not treat failed callback setup as a fatal operation error.
Failed callback setups usually result from exceeding the number of
allowed retries. Previously cp did not report an error during a
network outage but now does:
$ cp ~/s3-path/s3-file .
cp: error reading ‘/home/gaul/s3-path/s3-file’: Input/output error
cp: failed to extend ‘./s3-file’: Input/output error
1) Changed condition for retrying multipart error
Changes condition that 404 is not retrying, other case is retrying,
when multipart request failed.
2) file type wrong
fdcache.h file type is wrong, so that fixed it.

* Fixed a bug
Fixes a bug that is dead loop when s3fs listed in a directory with
directory objects which was not object(no information).
This bug made by r493, and reported by issue 389.
git-svn-id: http://s3fs.googlecode.com/svn/trunk@497 df820570-a93a-0410-bd06-b72b767a4274
1) Overflow
About over 4GB file, when st_size which is member stat structure,
the value is overflow.
Fixed this bug and fixed like this bug in all sources.
2) Changed retrying request
If s3fs gets 500 HTTP status for multipart request, s3fs retry
to send same request.
git-svn-id: http://s3fs.googlecode.com/svn/trunk@495 df820570-a93a-0410-bd06-b72b767a4274
1) Fixed bugs
* Rename objects
Fixes s3fs specifies wrong part number of multipart rename.
And s3fs adds x-amz-acl and x-amz-server-side-encryption
header when rename objects.
2) Changed retry logic for multipart uploading(and renaming)
Sometimes, s3fs gets 400 HTTP response for one of part from
S3 when s3fs uploads a large object by multipart.
New logic retries uploading failed part until "retries"
option count.
3) Added action on utility mode.
s3fs have had utility mode for displaying the result of REST
listing multipart uploading.
Changed this row result(xml) to list, after that, s3fs starts
conversation for removing it.
Then you can remove the object which is failed uploading by
multipart, and do not need to pay for that ever.

* Fixed a bug
Fixes a bug that the retrying multipart post request is not
complete, then it is fixed.
This is reported by Issue 371#32.

* Fixed a bug
Fixes a bug that is mis-coding about retrying Multipart Post.
This is reported by Issue 371#28.

1) Supported IAM role
Supports IAM role by option, that is instead of AccessKeyID/
SecretAccessKey.
Adds new option "iam_role" which is specified as IAM role
name.(like s3fs-c)

1) Fixed a bug(about curl_off_t)
Fixes a bug which is not use cast to curl_off_t from off_t(ssize_t)
at calling curl_easy_setopt with CURLOPT_POSTFIELDSIZE and
CURLOPT_INFILESIZE_LARGE.
Maybe this forgot cast occurred issue 471(failed multipart uploading).

1) Changed debug message level
Changes a level and format for a debugging message about
parallel multipart upload in curl.cpp
git-svn-id: http://s3fs.googlecode.com/svn/trunk@487 df820570-a93a-0410-bd06-b72b767a4274
1) Changed codes about memory leak
For memory leak, below codes are changed.
* calls malloc_trim function
* calls initializing NSS function, and adds configure
option "--enable-nss-init".
If libcurl is with NSS, s3fs initializes NSS manually.
This initializing NSS is enabled by "--enable-nss-init"
option at configure. if this option is specified, you
need "nss-devel" package.
* calls initializing libxml2(xmlInitParser).
* BIO functions have memory leak, calls CRYPTO_free_ex_data.
* changes cache structure.
* changes cache out logic to LRU.
* sets alignment for allcated memory in body data structure.
* adds ssl session into share handle. and adds nosscache option.
* deletes unused allocated memory.(bug)
* changes defaule parallel count of head request in readdir
(500->20)
* fixes some bugs.

1) Changed codes about initializing curl and openSSL
s3fs before this change called curl_global_init() two times
with curl_global_cleanup(). After reviewing this processing,
s3fs calls curl_global_init() one time.
Then s3fs_check_service function which checks user bucket
existing is called after calling fuse.
So this new processing does not have a problem, the codes
updated.
And about initializing openSSL(CRYPTO), old s3fs called only
static locking callback function(ex. CRYPTO_set_locking_callback()).
Added calling dynamic locking callback function for CRYPTO
(ex. CRYPTO_set_dynlock_lock_callback()).
git-svn-id: http://s3fs.googlecode.com/svn/trunk@479 df820570-a93a-0410-bd06-b72b767a4274
1) Added debugging message in s3fs_getattr
If s3fs runs with "f2" option for deep debugging message, s3fs_getattr
puts debugging message as file's uid/gid/mode.
2) Added curldbg option
Added new option "curldbg" which is for debugging curl http/https
information.
It implements by CURLOPT_VERBOSE on curl_easy_setopt function.

1) Fixed a bug
Fixed bugs(mis-coding) which is wrong prototype for md5hexsum, md5sum functions.
Issue 361: complie time error after running #make
Issue 360: 1.72 Will not compile on Ubuntu 12.04.2 (precise) i686
And fixed a code for initializing enum member in S3fsCurl class.

1) Fixed a bug
s3fs was wrong for request retry processing so far.
It was fixed.
Probably, Issue 343(1.7 having curl 35 + other disconnect issue) is
occurred by this bug.
git-svn-id: http://s3fs.googlecode.com/svn/trunk@468 df820570-a93a-0410-bd06-b72b767a4274
1) "virtual hosted-style request" for checking bucket
Old version calls "path-style request" for checking bucket at
initializing, then after this revision s3fs requests "virtual
hosted-style request".
This change is related to
"Operation not permitted - on any operation(Issue 362)".
2) Changed debugging message level
Changed debugging message level in prepare_url() from DPRNNN
to FPRNINFO.
