-What is mod_glusterfs?
-======================
-* mod_glusterfs is a module for apache written for efficient serving of files from glusterfs.
- mod_glusterfs interfaces with glusterfs using apis provided by libglusterfsclient.
-
-* this README speaks about installation of apache-1.3.x, where x is any minor version.
-
-Prerequisites for mod_glusterfs
-===============================
-Though mod_glusterfs has been written as a module, with an intent of making no changes to the way apache has
-been built, currently following points have to be taken care of:
-
-* module "so" has to be enabled, for apache to support modules.
-* since glusterfs is compiled with _FILE_OFFSET_BITS=64 and __USE_FILE_OFFSET64 flags, mod_glusterfs and apache
- in turn have to be compiled with the above two flags.
-
- $ tar xzvf apache-1.3.9.tar.gz
- $ cd apache-1.3.9/
- $ # add -D_FILE_OFFSET_BITS=64 -D__USE_FILE_OFFSET64 to EXTRA_CFLAGS in src/Configuration.
- $ ./configure --prefix=/usr --enable-module=so
- $ cd src
- $ ./Configure
- $ cd ../
- $ make install
- $ httpd -l | grep -i mod_so
- mod_so.c
-
-* if multiple apache installations are present, make sure to pass --with-apxs=/path/to/apxs/of/proper/version to configure script while building glusterfs.
-
-Build/Install mod_glusterfs
-===========================
-* mod_glusterfs is provided with glusterfs--mainline--3.0 and all releases from the same branch.
-
-* building glusterfs also builds mod_glusterfs. But 'make install' of glusterfs installs mod_glusterfs.so to
- glusterfs install directory instead of the apache modules directory.
-
-* 'make install' of glusterfs will print a message similar to the one given below, which is self explanatory.
- Make sure to use apxs of proper apache version in case of multiple apache installations. This will copy
- mod_glusterfs.so to modules directory of proper apache version and modify the appropriate httpd.conf to enable
- mod_glusterfs.
-
-**********************************************************************************************
-* TO INSTALL MODGLUSTERFS, PLEASE USE,
-* apxs -n mod_glusterfs -ia /usr/lib/glusterfs/1.4.0pre2/apache-1.3/mod_glusterfs.so
-**********************************************************************************************
-
-Configuration
-=============
-* Following configuration has to be added to httpd.conf.
-
- <Location "/glusterfs">
- GlusterfsLogfile "/var/log/glusterfs/glusterfs.log"
- GlusterfsLoglevel "warning"
- GlusterfsVolumeSpecfile "/etc/glusterfs/glusterfs-client.spec"
- GlusterfsCacheTimeout "600"
- GlusterfsXattrFileSize "65536"
- SetHandler "glusterfs-handler"
- </Location>
-
-* GlusterfsVolumeSpecfile (COMPULSORY)
- Path to the the glusterfs volume specification file.
-
-* GlusterfsLogfile (COMPULSORY)
- Path to the glusterfs logfile.
-
-* GlusterfsLoglevel (OPTIONAL, default = warning)
- Severity of messages that are to be logged. Allowed values are critical, error, warning, debug, none
- in the decreasing order of severity.
-
-* GlusterfsCacheTimeOut (OPTIONAL, default = 0)
- Timeout values for glusterfs stat and lookup cache.
-
-* GlusterfsXattrFileSize (OPTIONAL, default = 0)
- Files with sizes upto and including this value are fetched through the extended attribute interface of
- glusterfs rather than the usual open-read-close set of operations. For files of small sizes, it is recommended
- to use extended attribute interface.
-
-* With the above configuration all the requests to httpd of the form www.example.org/glusterfs/path/to/file are
- served from glusterfs.
-
-Miscellaneous points
-====================
-* httpd by default runs with username "nobody" and group "nogroup". Permissions of logfile and specfile have to
- be set suitably.
-
-* Since mod_glusterfs runs with permissions of nobody.nogroup, glusterfs has to use only login based
- authentication. See docs/authentication.txt for more details.
-
-* To copy the data served by httpd into glusterfs mountpoint, glusterfs can be started with the
- volume-specification file provided to mod_glusterfs. Any tool like cp can then be used.
-
-* To run in gdb, apache has to be compiled with -lpthread, since libglusterfsclient is multithreaded.
- If not on Linux gdb runs into errors like:
- "Error while reading shared library symbols:
- Cannot find new threads: generic error"
-
-* when used with ib-verbs transport, ib_verbs initialization fails.
- reason for this is that apache runs as non-privileged user and the amount of memory that can be
- locked by default is not sufficient for ib-verbs. to fix this, as root run,
-
- # ulimit -l unlimited
-
- and then start apache.
-
-TODO
-====
-* directory listing for the directories accessed through mod_glusterfs.

-What is mod_glusterfs?
-======================
-* mod_glusterfs is a module for apache written for efficient serving of files from glusterfs.
- mod_glusterfs interfaces with glusterfs using apis provided by libglusterfsclient.
-
-* this README speaks about installing mod_glusterfs for httpd-2.2 and higher.
-
-Prerequisites for mod_glusterfs
-===============================
-Though mod_glusterfs has been written as a module, with an intent of making no changes to
-the way apache has been built, currently following points have to be taken care of:
-
-* since glusterfs is compiled with _FILE_OFFSET_BITS=64 and __USE_FILE_OFFSET64 flags, mod_glusterfs and apache
- in turn have to be compiled with the above two flags.
-
- $ tar xzf httpd-2.2.10.tar.gz
- $ cd httpd-2.2.10/
- $ export CFLAGS='-D_FILE_OFFSET_BITS=64 -D__USE_FILE_OFFSET64'
- $ ./configure --prefix=/usr
- $ make
- $ make install
- $ httpd -l | grep -i mod_so
- mod_so.c
-
-* if multiple apache installations are present, make sure to pass --with-apxs=/path/to/apxs/of/proper/version
- to configure script while building glusterfs.
-
-Build/Install mod_glusterfs
-===========================
-* mod_glusterfs is provided with glusterfs--mainline--3.0 and all releases from the same branch.
-
-* building glusterfs also builds mod_glusterfs. But 'make install' of glusterfs installs mod_glusterfs.so to
- glusterfs install directory instead of the apache modules directory.
-
-* 'make install' of glusterfs will print a message similar to the one given below, which is self explanatory.
- Make sure to use apxs of proper apache version in case of multiple apache installations. This will copy
- mod_glusterfs.so to modules directory of proper apache version and modify the appropriate httpd.conf to enable
- mod_glusterfs.
-
-**********************************************************************************
-* TO INSTALL MODGLUSTERFS, PLEASE USE,
-* apxs -n glusterfs -ia /usr/lib/glusterfs/2.0.0rc4/apache/2.2/mod_glusterfs.so
-**********************************************************************************
-
-Configuration
-=============
-* Following configuration has to be added to httpd.conf.
-
- <Location "/glusterfs">
- GlusterfsLogfile "/var/log/glusterfs/glusterfs.log"
- GlusterfsLoglevel "warning"
- GlusterfsVolumeSpecfile "/etc/glusterfs/glusterfs-client.spec"
- GlusterfsCacheTimeout "600"
- GlusterfsXattrFileSize "65536"
- SetHandler "glusterfs-handler"
- </Location>
-
-* GlusterfsVolumeSpecfile (COMPULSORY)
- Path to the the glusterfs volume specification file.
-
-* GlusterfsLogfile (COMPULSORY)
- Path to the glusterfs logfile.
-
-* GlusterfsLoglevel (OPTIONAL, default = warning)
- Severity of messages that are to be logged. Allowed values are critical, error, warning, debug, none
- in the decreasing order of severity.
-
-* GlusterfsCacheTimeOut (OPTIONAL, default = 0)
- Timeout values for glusterfs stat and lookup cache.
-
-* GlusterfsXattrFileSize (OPTIONAL, default = 0)
- Files with sizes upto and including this value are fetched through the extended attribute interface of
- glusterfs rather than the usual open-read-close set of operations. For files of small sizes, it is recommended
- to use extended attribute interface.
-
-* With the above configuration all the requests to httpd of the form www.example.org/glusterfs/path/to/file are
- served from glusterfs.
-
-* mod_glusterfs also implements mod_dir and mod_autoindex behaviour for files under glusterfs mount.
- Hence it also takes the directives related to both of these modules. For more details, refer the
- documentation for both of these modules.

-* httpd by default runs with username "nobody" and group "nogroup". Permissions of logfile and specfile have to
- be set suitably.
-
-* Since mod_glusterfs runs with permissions of nobody.nogroup, glusterfs has to use only login based
- authentication. See docs/authentication.txt for more details.
-
-* To copy the data served by httpd into glusterfs mountpoint, glusterfs can be started with the
- volume-specification file provided to mod_glusterfs. Any tool like cp can then be used.
-
-* To run in gdb, apache has to be compiled with -lpthread, since libglusterfsclient is
- multithreaded. If not on Linux gdb runs into errors like:
- "Error while reading shared library symbols:
- Cannot find new threads: generic error"
-
-* when used with ib-verbs transport, ib_verbs initialization fails.
- reason for this is that apache runs as non-privileged user and the amount of memory that can be
- locked by default is not sufficient for ib-verbs. to fix this, as root run,
-
- # ulimit -l unlimited
-
- and then start apache.

-Introduction
-============
-mod_glusterfs is a module written for lighttpd to speed up the access of files present on glusterfs. mod_glusterfs uses libglusterfsclient library provided for glusterfs and hence can be used without fuse (File System in User Space).
-
-Usage
-=====
-To use mod_glusterfs with lighttpd-1.4, copy mod_glusterfs.c and mod_glusterfs.h into src/ of lighttpd-1.4 source tree, and apply the Makefile.am.diff to src/Makefile.am. Re-run ./autogen.sh on the top level of the lighttpd-1.4 build tree and recompile.
-
-# cp mod_glusterfs.[ch] /home/glusterfs/lighttpd-1.4/src/
-# cp Makefile.am.diff /home/glusterfs/lighttpd-1.4/
-# cd /home/glusterfs/lighttpd-1.4
-# patch -p1 < Makefile.am.diff
-# ./autogen.sh
-# ./configure
-# make
-# make install
-
-Configuration
-=============
-* mod_glusterfs should be listed at the begining of the list server.modules in lighttpd.conf.
-
-Below is a snippet from lighttpd.conf concerning to mod_glusterfs.
-
-$HTTP["url"] =~ "^/glusterfs" {
- glusterfs.prefix = "/glusterfs"
- glusterfs.document-root = "/home/glusterfs/document-root"
- glusterfs.logfile = "/var/log/glusterfs-logfile"
- glusterfs.volume-specfile = "/etc/glusterfs/glusterfs.vol"
- glusterfs.loglevel = "error"
- glusterfs.cache-timeout = 300
- glusterfs.xattr-interface-size-limit = "65536"
-}
-
-* $HTTP["url"] =~ "^/glusterfs"
- A perl style regular expression used to match against the url. If regular expression matches the url, the url is handled by mod_glusterfs. Note that the pattern given here should match glusterfs.prefix.
-
-* glusterfs.prefix (COMPULSORY)
- A string to be present at the starting of the file path in the url so that the file would be handled by glusterfs.
- Eg., A GET request on the url http://www.example.com/glusterfs-prefix/some-dir/example-file will result in fetching of the file "/some-dir/example-file" from glusterfs mount if glusterfs.prefix is set to "/glusterfs-prefix".
-
-* glusterfs.volume-specfile (COMPULSORY)
- Path to the the glusterfs volume specification file.
-
-* glusterfs.logfile (COMPULSORY)
- Path to the glusterfs logfile.
-
-* glusterfs.loglevel (OPTIONAL, default = warning)
- Allowed values are critical, error, warning, debug, none in the decreasing order of severity of error conditions.
-
-* glusterfs.cache-timeout (OPTIONAL, default = 0)
- Timeout values for glusterfs stat and lookup cache.
-
-* glusterfs.document-root (COMPULSORY)
- An absolute path, relative to which all the files are fetched from glusterfs.
-
-* glusterfs.xattr-interface-size-limit (OPTIONAL, default = 0)
- Files with sizes upto and including this value are fetched through the extended attribute interface of glusterfs rather than the usual open-read-close set of operations. For files of small sizes, it is recommended to use extended attribute interface.

-Introduction
-============
-mod_glusterfs is a module written for lighttpd to speed up the access of files present on glusterfs. mod_glusterfs uses libglusterfsclient library provided for glusterfs and hence can be used without fuse (File System in User Space).
-
-Usage
-=====
-To use mod_glusterfs with lighttpd-1.5, copy mod_glusterfs.c and mod_glusterfs.h into src/ of lighttpd-1.5 source tree, and apply the Makefile.am.diff to src/Makefile.am. Re-run ./autogen.sh on the top level of the lighttpd-1.5 build tree and recompile.
-
-# cp mod_glusterfs.[ch] /home/glusterfs/lighttpd-1.5/src/
-# cp Makefile.am.diff /home/glusterfs/lighttpd-1.5/
-# cd /home/glusterfs/lighttpd-1.5
-# patch -p1 < Makefile.am.diff
-# ./autogen.sh
-# ./configure
-# make
-# make install
-
-Configuration
-=============
-* mod_glusterfs should be listed at the begining of the list server.modules in lighttpd.conf.
-
-Below is a snippet from lighttpd.conf concerning to mod_glusterfs.
-
-$HTTP["url"] =~ "^/glusterfs" {
- glusterfs.prefix = "/glusterfs"
- glusterfs.logfile = "/var/log/glusterfs-logfile"
- glusterfs.document-root = "/home/glusterfs/document-root"
- glusterfs.volume-specfile = "/etc/glusterfs/glusterfs.vol"
- glusterfs.loglevel = "error"
- glusterfs.cache-timeout = 300
- glusterfs.xattr-interface-size-limit = "65536"
-}
-
-* $HTTP["url"] =~ "^/glusterfs"
- A perl style regular expression used to match against the url. If regular expression matches the url, the url is handled by mod_glusterfs. Note that the pattern given here should match glusterfs.prefix.
-
-* glusterfs.prefix (COMPULSORY)
- A string to be present at the starting of the file path in the url so that the file would be handled by glusterfs.
- Eg., A GET request on the url http://www.example.com/glusterfs-prefix/some-dir/example-file will result in fetching of the file "/some-dir/example-file" from glusterfs mount if glusterfs.prefix is set to "/glusterfs-prefix".
-
-* glusterfs.volume-specfile (COMPULSORY)
- Path to the the glusterfs volume specification file.
-
-* glusterfs.logfile (COMPULSORY)
- Path to the glusterfs logfile.
-
-* glusterfs.loglevel (OPTIONAL, default = warning)
- Allowed values are critical, error, warning, debug, none in the decreasing order of severity of error conditions.
-
-* glusterfs.cache-timeout (OPTIONAL, default = 0)
- Timeout values for glusterfs stat and lookup cache.
-
-* glusterfs.document-root (COMPULSORY)
- An absolute path, relative to which all the files are fetched from glusterfs.
-
-* glusterfs.xattr-interface-size-limit (OPTIONAL, default = 0)
- Files with sizes upto and including this value are fetched through the extended attribute interface of glusterfs rather than the usual open-read-close set of operations. For files of small sizes, it is recommended to use extended attribute interface.

-/* bdb based storage translator - named as 'bdb' translator

- * their parent directory.
- * 2. REGULAR FILE - regular files are stored as records in the storage_db.db
- * present in the directory. regular files also have an entry in ns_db.db
- *
- * Internally bdb has a maximum of three different types of logical files
- * associated with each directory:
- * 1. storage_db.db - storage database, used to store the data corresponding to
- * regular files in the form of key/value pair. file-name is the 'key' and
- * data is 'value'.
- * 2. directory (all subdirectories) - any subdirectory will have a regular
- * directory entry.

- * there are four possibilities for a file being looked up:
- * 1. file exists and is a directory.
- * 2. file exists and is a symlink.
- * 3. file exists and is a regular file.
- * 4. file does not exist.
- * case 1 and 2 are handled by doing lstat() on the @loc. if the file is a
- * directory or symlink, lstat() succeeds. lookup continues to check if the
- * @loc belongs to case-3 only if lstat() fails.
- * to check for case 3, bdb_lookup does a bdb_db_iread() for the given @loc.
- * (see description of bdb_db_iread() for more details on how @loc is transformed
- * into db handle and key). if check for case 1, 2 and 3 fail, we proceed to
- * conclude that file doesn't exist (case 4).
- *
- * @frame: call frame.
- * @this: xlator_t of this instance of bdb xlator.
- * @loc: loc_t specifying the file to operate upon.
- * @need_xattr: if need_xattr != 0, we are asked to return all the extended
- * attributed of @loc, if any exist, in a dictionary. if @loc is a regular
- * file and need_xattr is set, then we look for value of need_xattr. if
- * need_xattr > sizo-of-the-file @loc, then the file content of @loc is
- * returned in dictionary of xattr with 'glusterfs.content' as dictionary key.
- *
- * NOTE: bdb currently supports only directories, symlinks and regular files.
- *
- * NOTE: bdb_lookup returns the 'struct stat' of underlying file itself, in
- * case of directory and symlink (st_ino is modified as bdb allocates its own
- * set of inodes of all files). for regular files, bdb uses 'struct stat' of
- * the database file in which the @loc is stored as templete and modifies
- * st_ino (see bdb_inode_transform for more details), st_mode (can be set in
- * volfile 'option file-mode <mode>'), st_size (exact size of the @loc
- * contents), st_blocks (block count on the underlying filesystem to
- * accomodate st_size, see BDB_COUNT_BLOCKS in bdb.h for more details).
