09fc2593e3 Fixed bugs and Changed utility mode
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.

42b74c9d2e Changes codes
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.

7ce8135fa9 Changes codes
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()).

b3682f87d2 Fixed bugs(Issue 363)
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.

d7689151ab Fixed Issue 229 and Changes codes
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.

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.

5a035a33f0 Changes codes
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.

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.
