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.

3274f58948 Changes codes for performance(part 3)
* 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.)

1c93dd30c1 Changes codes
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).

1095b7bc52 Changes codes
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.

d1a17cbe3d Fixed Issue 352 and bugs
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.

ad19ffa458 Changes codes
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.

45950044f7 Changes codes
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.

1) Fixed a bug(forgot removing temporary files)
    When s3fs gets a error from fwrite in multipart uploading function,
    s3fs does not remove a temporary file.

2) Fixed a bug(wrong prototype of function)
    The prototype of function for CURLSHOPT_UNLOCKFUNC
    is wrong.

3) Changed codes

9833c7e589 Fixed Issue 226
1) Patch adding support for SSE( Issue 226 )
    Supports SSE(Server-Side Encryption) and adds "use_sse" option.
    * Specifications
       When "use_sse" option is specified as "1", s3fs adds "x-amz-server-side-encryption"
       header as "AES256".
       But it only does when objects upload(writing object). 
       When you do chmod/chown/chgrp/touch/mv commands, s3fs does not 
       add this header and inherit SSE mode from oroginal object. 
    * Notice
       "use_sse" option can not specify with "use_rrs" because we get signature
       error from S3.

List of Changes
==========================
1) Fixes bugs - r428
    * Fixes a bug which object owner/group is set wrong id.
    * The permission of mount point when allow_other option is 
       specified.
    * Fixes a bug about permission
       when the directory permission is 0557, other user(who is not
       owner and same group) gets a permission error when making 
       file or directory in that dir.
    * Fixes a bug( Issue 340 )
       Fixes compile error about "blkcnt_t".

2) Fixes a bug( Issue 429 ) - r429
    Changes that s3fs always uses own dns cache, and adds "nodnscache"
    option. If "nodnscache" is specified, s3fs does not use dns cache as 
    before. s3fs keeps DNS cache for 60 senconds by libcurl's default.

3) Fixes a bug( Issue 235 ) - r430
    Fixes a CURLE_COULDNT_CONNECT error when s3fs reads 
    objects header information.
    * max request in curl_multi request is 500 and s3fs loops to call 
       curl_multi.
    * retries to call request which returns error as CURLE_COULDNT_CONNECT.

4) Fixes a bug - r431
    Fixed a bug(failed all multi head request when mounting bucket+path)

5) FIxes a bug( Issue 241 ) - r432

c686a3b2c0 Fixed Issue 241
1) problems with fseek and s3fs(Issue 241)
   This problem is that s3fs returns file stat(size) when client already has opened file discriptor and client modifies file before saving fd.
   So that, client adds bytes into file, but s3fs_getattr() function returns original size before changing.
   Changes codes for that s3fs returns size from opened file discriptor, if client already opens the file.
   * Changes s3fs.cpp
   * Adds fdcache.cpp fdcache.h

    When the mount point is specified with sub-directory(mounting with 
    "bucket:/path"), internally all curl_multi head request in s3fs_readdir() 
    function failed.
    This reason is that the head curl_multi request is not specified with 
    mount path.
    This is a bug, and fixed.

1) Problems using encrypted connection to s3(Issue 235)
    In s3fs_readdir() function, s3fs gets CURLE_COULDNT_CONNECT error when s3fs reads objects header information.
    Probably, this problem is too many request in curl_multi request.
    Then s3fs codes are changed:
    * max request in curl_multi request is 500 and s3fs loops to call curl_multi.
    * retries to call request which returns error as CURLE_COULDNT_CONNECT.

   Changes that s3fs always uses own dns cache, and adds "nodnscache" option.
   If "nodnscache" is specified, s3fs does not use dns cache as before.
   s3fs keeps DNS cache for 60 senconds by libcurl's default.

be5fa78032 Fixed Issue 340 and some bugs.
1) Fixes a bug which object owner/group is set wrong id.
    When do chown(chgrp) command without group(owner), s3fs set wrong id(-1) 
    for group(owner) id.
    Fixes this bug.

2) The permission of mount point when allow_other option is specified.
    When allow_other option is specified, s3fs forces the mount point directory 
    permission to set executable permission(mode | 0111).

3) Fixes a bug about permission
    For example, when the directory permission is 0557, other user(who is not owner
    and same group) gets a permission error when making file or directory in that dir.
    Fixes this bug.

cd21f567a1 Summary of Changes(1.68 -> 1.69)
==========================
List of Changes
==========================
1) Fixes a bug - r418, r419
   Fixed a bug that s3fs failed to get stats when the max_stat_cache_size option was specified 0.

2) Fixed a bug( Issue 291) - r420
   Fixes ( Issue 291 ) "Man file has wrong permissions for passwd file",  
   then changes man page.
   Checks passwd file permission strictly.
   Fixes a bug that s3fs continued to run after finding invalid passwd file 
   permission.

3) Added enable_noobj_cache option for no-existing object - r420, r421
   Adds enable_noobj_cache option(default disable) for performance.
   This option is specified, s3fs memorizes in stat cache that the object
   (file or directory) does not exist.

4) Fixed a bug( Issue 240 ) - r421
   Fixes ( Issue 240 ) "Cannot Mount Path in Bucket".
   Changes man page.

5) Supported s3sync'ed object( Issue 31 ) - r422
   Supports HTTP headers which made by s3sync.
   It means that s3fs supported HTTP headers are x-amz-meta-owner, 
   x-amz-meta-permissions and x-amz-meta-group.

6) Added enable_content_md5 option - r423
   Adds enable_content_md5 option(default disable).
   If "enable_content_md5" option is specified, s3fs puts the object with 
   "Content-MD5" header when s3fs sending small object(under 20MB).

7) Supported uid/gid option - r424
   Supports uid/gid mount(fuse) option.

fb30405aef Supported uid/gid options
1) Supports uid/gid options
    Fuse(and mount) option "uid" and "gid" is supported.
    
*) Fixes some issues
    So these option are supported, some issue which are permission or access problem are solved.
    ex. FIle permissions 000(Issue 337)

9da497af45 Added enable_content_md5 option
1) Adds enable_content_md5 option
   When s3fs uploads large object(over 20MB), s3fs checks always ETag(MD5) in each multipart's response.
   But for small objects, s3fs does not check MD5.
   This new option enables for checking MD5 of uploading object.
   If "enable_content_md5" option is specified, s3fs puts the object with "Content-MD5" header.

   The checking MD5 value is not default, because it increases some of user's cpu usage.
   (The default value may be replaced in the future.)

715b837a2b Fixed Issue 31 and Cleanup codes
1) s3sync'ed files not supported(Issue 31)
    Supports HTTP headers which made by s3sync.
    Supported new HTTP headers are x-amz-meta-owner, 
    x-amz-meta-permissions and x-amz-meta-group.
    s3fs read and understand these headers, but s3fs 
    gives priority to s3fs's headers over these headers.

2) Cleanups codes
    Cleanups some codes about issue 31.

c862ee40ea Fixed issue 240 and some bugs.
1) Cannot Mount Path in Bucket(Issue 240)
    Changes man page for this issue("bucket[:path]" -> "bucket[:/path]").
    And so s3fs did not work with mount path, fixed it.

2) Fixes other bug about renaming directory
    Fixes a bug caused by r420, which fails to rename directory.

6b78bfdf4b Fixed issue 291, and Adds "disable_noobj_cache" option.
1) Man file has wrong permissions for passwd file(Issue 291)
    Fixes man page for wrong permissions of passwd file.

2) Fixes a bug and Strictly checks passwd file permission.
    * Fixes a bug about checking passwd file permission.
       A bug is that s3fs continues to run after s3fs finds invalid passwd 
      file permission.
    * Checks passwd file strictly.
       Before this revision, s3fs allows executable permission for a 
       passwd file and  allows group writable permission for a passwd 
       file(which is not "/etc/passwd-s3fs").
       New s3fs checks permission strictly, that is  /etc/passwd-s3fs is 
       allowed owner readable/writable and group readable, and  the 
       passwd file(which is not "/etc/passwd-s3fs") is allowed only owner 
       readable/writable.

3) Adds disable_noobj_cache option for no-existing object.
    s3fs v1.68 always has to check whether file(or sub directory) exists 
    under object(path)  when s3fs does some command, since s3fs has 
    recognized a directory which does not exist and has files or sub 
    directories under itself.
    It increases ListBucket request and makes performance bad.
    For performance if the disable_noobj_cache option is specified, s3fs 
    memorizes in stat cache that the object(file or directory) does not exist.

ae2d1eda84 Summary of Changes(1.67 -> 1.68)
==========================
List of Changes
==========================
1) Fixes a bug(Issue 320) - r408, r411, r412
   Fixes (Issue 320) "Spurious I/O errors"
   (http://code.google.com/p/s3fs/issues/detail?id=320)

   When the s3fs gets error in upload loop, it try to re-upload without seeking
   the fd. This is a bug for this issue.
   Please see detail in r408, r411 and r412.

2) Fixes a bug(Issue 293) - r409
   Fixes (Issue 293) "Command line argument bucket: causes segv"
   (http://code.google.com/p/s3fs/issues/detail?id=293)

   If it specifies the bucket name which is terminated ":", the s3fs crushes.
   Please see detail in r409.

3) Supports a option(Issue 265) - r410
   Supports (Issue 265) "Unable to mount to a non empty directory"
   (http://code.google.com/p/s3fs/issues/detail?id=265)

   Supported "nonempty" fuse/mount option.
   Please see detail in r410.

4) Supports other S3 clients(Issue 27) - r413, r.414
   Supports (Issue 27) "Compatability with other S3FS clients"

   *** "_$folder$" dir object
    Supports the directory object which made by s3fox. Its name has "_$folder$"
    suffixes. On s3fs, that directory object is listed normal directory name 
    without "_$folder$".
    Please be careful when you change object attributes(rename, chmod, chown,
    touch), because the s3fs remakes the directory object without "_$folder$"
    sufixes. This means the object is re-made by the s3fs.

   *** no dir object
    Supports the directory which is no objects.
    If there is a object which has "/" charactor(ex. "<bucket>/dir/file"), the
    directory("dir") object is no object.
    Example, you can upload the object which name is "s3://bucket/dir/file" by
    the s3cmd(or other S3 clients like s3cmd).
    Then on thie case, the "dir" is not object in bucket.
    This s3fs version understands this case.
    Please be careful when you change object attributes(rename, chmod, chown,
    touch), because the s3fs makes new directory object.

   Please see detail in r413 and r414.

b973eaae44 Changed codes for issue: 27(+)
1) Feature Request: Compatability with other S3FS clients(Issue: 27)
    Rechanges source code.

2) For other S3 clients
    Supports the directory which is no objects.
    If there is a object which has "/" charactor(ex. "<bucket>/dir/file"), the directory("dir") object is no object.
    Exsample, you can upload the object which name is "s3://bucket/dir/file" by the s3cmd.
    Then the "dir" is not object in bucket("dir").
    This s3fs codes understands this case.

36447a23eb Fixed issue: 27
1) Feature Request: Compatability with other S3FS clients(Issue: 27)
    Supported the directory object which made by s3fox. Its name has "_$folder$" suffixes.
    On s3fs, that directory object is listed normal directory name without "_$folder$".
    You need careful when you change object attributes(rename, chmod, chown, touch), because the s3fs remakes the directory object after that object(which has "_$folder$" suffix)
    After changing the object attributes, the object name does not have "_$folder$" suffix.
    It means the object is remade by s3fs.

2) Other
    Fixes bugs which are found when this issue is fixed.

eaf43e6f59 Fixed issue: 320(++)
1) Changes calling fread/fwrite logic(Issue: 320)
    In conjunction with this issue, the opened file discripter is rewinded after reading/writing.
    The put_local_fd() and get_localfd() function always returns rewinded fd.

a92a4c0a4f Fixed issue: 320
1) Changes calling fread/fwrite logic(Issue: 320)
    The s3fs functions are called by doing rsync command, the calling order is s3fs_create, s3fs_truncate, s3fs_flush.
    After the s3fs_truncate uploads the file, the s3fs_flush uploads the file again wothout rewinding fd.
    It is this issue bug, the s3fs_flush read EOF and put error.
    Then I changes the code  that is calling the lseek and seeking FD to head of file before fread/fwrite.

9310c0b653 Summary of Changes(1.66 -> 1.67)
==========================
List of Changes
==========================
1) Fixes a bug(r403)
    Fixes (Issue: 326) "segfault using s3fs 1.6.5".
    (http://code.google.com/p/s3fs/issues/detail?id=326)

    The my_curl_easy_perform() function is not clearing the buffer(struct BodyStruct body) before retrying the request.
    And the "struct BodyStruct" is changed to "Class BodyData".
    New class is same as BodyStruct, but handling memory is automatically.
    And added a argument for my_curl_easy_perform().
    This function is needed the buffer pointer, but the arguments is only for body buffer.
    Then I added the buffer pointer for header buffer.

2) Fixes a bug(r404)
    Fixes (Issue: 328) "Problem with allow_other option".
    (http://code.google.com/p/s3fs/issues/detail?id=328)

    The return value in get_username() function is wrong value(NULL) when there is not user id in passwd file.

3) Fixes memory leak(r403)
  In get_object_name() function, there was a memory leak.

8bd1483374 Summary of Changes(1.65 -> 1.66)
==========================
List of Changes
==========================
1) Fixes bugs
    Fixes Issue 321: "no write permission for non-root user".
    (http://code.google.com/p/s3fs/issues/detail?id=321)
    Fixes a bug which s3fs does not set uid/gid headers when making symlink.

2) Cleanup  code.
    Adds a common function which  converts the Last-Modified header to utime.
    Deletes the useless cord and arranged it.

3) xmlns
    Changes that s3fs can decide using the xmlns url automatically.
    Then the noxmlns option is not needed anymore, but it is left.

4) Changes cache for performance
    Changes stat cache, it accumulates stat information and some headers.
    By adding some headers into cache, s3fs does not need to call curl_get_headers function.
    After changing, one cache entry increases in about 500 bytes from about 144 byte.
    
    Adds one condition to get out of the cache, that condition is by looking object's ETag.
    It works good for noticing changes about obojects.
