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) Changed buffer size for file size
Changes a internal buffer size from size_t to offt_t.
It is a bug for 32 bit OS enviroment.
git-svn-id: http://s3fs.googlecode.com/svn/trunk@496 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.

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) Fixed Issue 371
Fixes a bug which is wrong return value in s3fs_truncate function(mis-coding).
Issue 371: ftruncate failed
git-svn-id: http://s3fs.googlecode.com/svn/trunk@486 df820570-a93a-0410-bd06-b72b767a4274
1) Re-Fixed Issue 368
Changes that s3fs checks always object stat information before opening it.
Then the object updates other s3fs process or other client, s3fs can know
it.
(Issue 368)1.73: Updating existing file on server 'a' does not change length
of file on server 'b'
git-svn-id: http://s3fs.googlecode.com/svn/trunk@485 df820570-a93a-0410-bd06-b72b767a4274
1) fixed a bug
fixes a code in s3fs.cpp.
It freed memory twice because of careless.
git-svn-id: http://s3fs.googlecode.com/svn/trunk@484 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.

git-svn-id: http://s3fs.googlecode.com/svn/trunk@481 df820570-a93a-0410-bd06-b72b767a4274
1) Fixed Issue 321
Fixed a bug that a value of umask option is not reflected
definitely.
(Issue 321) no write permission for non-root user
2) Fixed a bug about utimens
Fixed a bug that utimens function cloud not set value to the
other user's object which does not allowed writable.
3) Strictly option check.
Fixed checking s3fs options strictly.
git-svn-id: http://s3fs.googlecode.com/svn/trunk@480 df820570-a93a-0410-bd06-b72b767a4274
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@475 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.

Issue 364: Feature request: Control cache size
git-svn-id: http://s3fs.googlecode.com/svn/trunk@472 df820570-a93a-0410-bd06-b72b767a4274
1) Fixed Issue 363
Fixed a bug which has below reason.
Fuse does not wait finishing "release file descriptor" function
called by fuse, and fuse runs(calls) next processing(commands).
Then s3fs could not clear stats cache information for that file
before calling next processing, and s3fs uses old stats cache
information.
So that, s3fs clears stats cache in release function at first.
And found two bad codes(but these codes do not influence normal
movement) in fdcache.cpp and fixed these.
Issue 363: make check failing inconsistently

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.
git-svn-id: http://s3fs.googlecode.com/svn/trunk@467 df820570-a93a-0410-bd06-b72b767a4274
1) Fixed bugs
Fixes below bugs( format error and undefined fund ).
* 1.72 Will not compile on Ubuntu 12.04.2 (precise) i686(Issue 360)
* complie time error after running #make(Issue 361)
I'll close these Issue if I can confirm that these problem was solved.
git-svn-id: http://s3fs.googlecode.com/svn/trunk@466 df820570-a93a-0410-bd06-b72b767a4274
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.

git-svn-id: http://s3fs.googlecode.com/svn/trunk@460 df820570-a93a-0410-bd06-b72b767a4274
1 ) Fixed a bug
Since r458, s3fs uses stat files of cache files. But s3fs forgot removing these
stat files when s3fs removed cache files.
Fixed this bug.
git-svn-id: http://s3fs.googlecode.com/svn/trunk@459 df820570-a93a-0410-bd06-b72b767a4274
* Summay
This revision includes big change about temporary file and local cache file.
By this big change, s3fs works with good performance when s3fs opens/
closes/syncs/reads object.
I made a big change about the handling about temporary file and local cache
file to do this implementation.
* Detail
1) About temporary file(local file)
s3fs uses a temporary file on local file system when s3fs does download/
upload/open/seek object on S3.
After this revision, s3fs calls ftruncate() function when s3fs makes the
temporary file.
In this way s3fs can set a file size of precisely length without downloading.
(Notice - ftruncate function is for XSI-compliant systems, so that possibly
you have a problem on non-XSI-compliant systems.)
By this change, s3fs can download a part of a object by requesting with
"Range" http header. It seems like downloading by each block unit.
The default block(part) size is 50MB, it is caused the result which is default
parallel requests count(5) by default multipart upload size(10MB).
If you need to change this block size, you can change by new option
"fd_page_size". This option can take from 1MB(1024 * 1024) to any bytes.
So that, you have to take care about that fdcache.cpp(and fdcache.h) were
changed a lot.
2) About local cache
Local cache files which are in directory specified by "use_cache" option do
not have always all of object data.
This cause is that s3fs uses ftruncate function and reads(writes) each block
unit of a temporary file.
s3fs manages each block unit's status which are "downloaded area" or "not".
For this status, s3fs makes new temporary file in cache directory which is
specified by "use_cache" option. This status files is in a directory which is
named "<use_cache sirectory>/.<bucket_name>/".
When s3fs opens this status file, s3fs locks this file for exclusive control by
calling flock function. You need to take care about this, the status files can
not be laid on network drive(like NFS).
This revision changes about file open mode, s3fs always opens a local cache
file and each status file with writable mode.
Last, this revision adds new option "del_cache", this option means that s3fs
deletes all local cache file when s3fs starts and exits.
3) Uploading
When s3fs writes data to file descriptor through FUSE request, old s3fs
revision downloads all of the object. But new revision does not download all,
it downloads only small percial area(some block units) including writing data
area.
And when s3fs closes or flushes the file descriptor, s3fs downloads other area
which is not downloaded from server. After that, s3fs uploads all of data.
Already r456 revision has parallel upload function, then this revision with
r456 and r457 are very big change for performance.
4) Downloading
By changing a temporary file and a local cache file, when s3fs downloads a
object, it downloads only the required range(some block units).
And s3fs downloads units by parallel GET request, it is same as a case of
uploading. (Maximum parallel request count and each download size are
specified same parameters for uploading.)
In the new revision, when s3fs opens file, s3fs returns file descriptor soon.
Because s3fs only opens(makes) the file descriptor with no downloading
data. And when s3fs reads a data, s3fs downloads only some block unit
including specified area.
This result is good for performance.
5) Changes option name
The option "parallel_upload" which added at r456 is changed to new option
name as "parallel_count". This reason is this option value is not only used by
uploading object, but a uploading object also uses this option. (For a while,
you can use old option name "parallel_upload" for compatibility.)
git-svn-id: http://s3fs.googlecode.com/svn/trunk@458 df820570-a93a-0410-bd06-b72b767a4274
1) For uploading performance(part 2)
Changed a codes about uploading large object(multipart uploading).
This revision does not make temporary file when s3fs uploads large object by multipart uploading.
Before this revision, s3fs made temporary file(/tmp/s3fs.XXXXX) for multipart, but it was not good for performance.
So that, new codes do not use those files, and s3fs reads directly large object from s3fs's cache file.
2) Some value to symbol
Changed some value to symbol(define).
git-svn-id: http://s3fs.googlecode.com/svn/trunk@457 df820570-a93a-0410-bd06-b72b767a4274
1) For uploading performance(part 1)
Changed a code for large object uploading.
New codes makes s3fs send parallel requests when s3fs uploads large
object(20MB) by multipart post.
And added new "parallel_upload" option, which limits parallel request
count which s3fs requests at once.
This option's default value is "5", and you can change this value. But it
is necessary to set this value depending on a CPU and a network band.
s3fs became to work good performance by this option, please try to set
your value for this option.
2) Changes debugging messages
Changed debugging message in s3fs.cpp.
git-svn-id: http://s3fs.googlecode.com/svn/trunk@456 df820570-a93a-0410-bd06-b72b767a4274
1) Changes a code in PutRequest function
Changed a code in S3fsCurl:: PutRequest function to duplicate file discriptor in
this function.
2) Changes debugging messages
Changed debugging message's indent in curl.cpp functions.
git-svn-id: http://s3fs.googlecode.com/svn/trunk@455 df820570-a93a-0410-bd06-b72b767a4274
1) Fixed a bug
When something error occured in multipart uploading process, s3fs forgets to free memory.
(from r451)
Fixed this bug.
git-svn-id: http://s3fs.googlecode.com/svn/trunk@454 df820570-a93a-0410-bd06-b72b767a4274
1) Option syntax verbosity in doc ( Issue 352 )
Before this revision(version), "use_rrs" option needs to set a parameter like "use_sse" option.
But this option does not need a parameter, specified "use_rrs" option means enabled RRS.
(because RRS is desabled by default.)
After this revision, "use_rrs" option can be specified without a parameter, and "use_sse" too.
Changed codes, man page and help page.
Please notice, for old version "use_rrs"(and "use_sse") can be specified with a parameter("1" or "0") yet.
2) Fixes a bug about analizing "use_sse" option.
Fixed a bug in r451, "use_sse" option is not worked because s3fs mistook to call function for "use_rrs".
3) Fixes a memory leak.
Fixed a memory leak in r451.
Fixed that the curl_slist_sort_insert() function forgot to free memory.
git-svn-id: http://s3fs.googlecode.com/svn/trunk@452 df820570-a93a-0410-bd06-b72b767a4274
1) Adds new S3fsCurl class
Added new S3fsCurl class instead of directly calling curl function.
This class is lapping curl function for s3fs(AWS S3 API).
2) Changes codes about adding S3fsCurl class
Changed and deleted classes and structures which are related to curl in curl.cpp/curl.h.
Changed codes which are calling S3 API with curl in s3fs.cpp.
3) Deletes YKIES macro
Deleted YIKES macro, because this macro is used no more.
4) Changes a code
s3fs does not get good performance because s3fs copies each byte while downloading.
So that the codes is changed instead of memcpy, then s3fs performance not a little improves.
5) Fixes a bug
When s3fs renames a file, s3fs does not use the value which is specified by servicepath option.
Fixed this bug.

1) Changes FdCache class(cleanup codes)
The FdCache class is for caching file discriptor.
This class is modified as adding reference count for file discriptor and
removing pid for each path.

1) Changes codes for performance and request's costs
s3fs gets object's attributes by using HEAD request.
Directory objects is following 4 type:
a) name type is "dir", with meta information
b) name type is "dir", without meta information(but has files in itself)
c) name type is "dir/", with(out) meta information
d) name type is "dir_$folder$", with(out) meta information
The codes is changed to order checking directory object.
So that, s3fs decreases requests for checking objects.
Before version has a bug, that is s3fs can not be recognizable type-b)
definitely when s3fs check the object directly.(but s3fs can, when s3fs
check the object by listing)
This change fixes this bug.
2) Adds "multireq_max" option
Added "multireq_max" option is maximum number of parallel request
for listing objects.
This changes is possible to solve CURLE_COULDNT_CONNECT.
If this option can not solve it, this option will be useful for tuning
performance by each.
