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.

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.

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.)

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.

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.

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.

7477224d02 Fixed Issue 304
1) s3fs should cache DNS lookups?(Issue 304)
   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.

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.)

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.

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.
