+ *
+ * As we lookup, operations may be underway on the entry name and the
+ * inode. In lookup() we are primarily concerned only with the entry
+ * operations. If the entry is getting unlinked or renamed, we detect
+ * what operation is underway by querying for on-going transactions and
+ * pending self-healing on the entry through xdata.
+ *
+ * If the entry is a file/dir, it may need self-heal and/or in a
+ * split-brain condition. Lookup is not the place to worry about these
+ * conditions. Outcast marking will naturally handle them in the read
+ * paths.
+ *
+ * Here is a brief goal of what we are trying to achieve:
+ *
+ * - LOOKUP on all subvolumes concurrently, querying on-going transaction
+ * and pending self-heal info from the servers.
+ *
+ * - If all servers reply the same inode type and GFID, the overall call
+ * MUST be a success.
+ *
+ * - If inode types or GFIDs mismatch, and there IS either an on-going
+ * transaction or pending self-heal, inspect what the nature of the
+ * transaction or pending heal is, and select the appropriate subvolume's
+ * reply as the winner.
+ *
+ * - If inode types or GFIDs mismatch, and there are no on-going transactions
+ * or pending self-heal on the entry name on any of the servers, fail the
+ * lookup with EIO. Something has gone wrong beyond reasonable action.

+ it to stable storage, we (being in userspace) have no mechanism
+ to get notified when the write became "stable".
+
+ This means we need take matter into our own hands and issue an
+ fsync() EVEN IF THE APPLICATION WAS PERFORMING UNSTABLE WRITES,

+ fsync() acknowledgement before initiating the hard POST-OP.

+ part of the FOP itself. The same holds true for NFS stable

+
+Hard link migration is carried out in three stages.
+
+(Say there are n hardlinks)
+Stage 1: Setting the new hashed subvol information on the 1st hardlink
+ encountered (linkto setxattr)
+
+Stage 2: Creating hardlinks on new hashed subvol for the 2nd to (n-1)th
+ hardlink
+
+Stage 3: Physical migration of the data file for nth hardlink
+
+Why to deem "-2" as success and not "0":
+
+ dht_migrate_file expects return value "0" from _is_file_migratable if
+the file has to be migrated.
+
+ _is_file_migratable returns zero only when it is called with the
+flag "GF_DHT_MIGRATE_HARDLINK_IN_PROGRESS".
+
+ gf_defrag_handle_hardlink calls dht_migrate_file for physical migration
+of the data file with the flag "GF_DHT_MIGRATE_HARDLINK_IN_PROGRESS"
+
+Hence, gf_defrag_handle_hardlink returning "0" for success will force
+"dht_migrate_file" to migrate each of the hardlink which is not intended.
+
+For each of the three stage mentioned above "-2" will be returned and will
+be converted to "0" in dht_migrate_file.

- * This functionality of 'unify' will enable glusterfs to support storage
- * system failure, and maintain consistancy. This works both ways, ie, when
- * an entry (either file or directory) is found on namespace server, and not
- * on storage nodes, its created in storage nodes and vica-versa.
- *
- * The two fops, where it can be implemented are 'getdents ()' and 'lookup ()'

- * the child node, and directories to be present on all the nodes.
- *
- * NOTE:
- * Now, unify has support for global namespace, which is used to keep a
- * global view of fs's namespace tree. The stat for directories are taken
- * just from the namespace, where as for files, just 'ia_ino' is taken from
- * Namespace node, and other stat info is taken from the actual storage node.
- * Also Namespace node helps to keep consistant inode for files across
- * glusterfs (re-)mounts.

+ * cblock (or cipher block). A logical unit in a file.
+ * cblock size is defined as the number of bits
+ * in an input (or output) block of the block
+ * cipher (*). Cipher block size is a property of
+ * cipher algorithm. E.g. cblock size is 64 bits
+ * for DES, 128 bits for AES, etc.
+ *
+ * atomic cipher A cipher algorithm, which requires some chunks of
+ * algorithm text to be padded at left and(or) right sides before
+ * cipher transaform.
+ *
+ *
+ * block (atom) Minimal chunk of file's data, which doesn't require
+ * padding. We'll consider logical units in a file of
+ * block size (atom size).
+ *
+ * cipher algorithm Atomic cipher algorithm, which requires the last
+ * with EOF issue incomplete cblock in a file to be padded with some
+ * data (usually zeros).
+ *
+ *
+ * operation, which reading/writing from offset, which is not aligned to
+ * forms a gap at to atom size
+ * the beginning
+ *
+ *
+ * operation, which reading/writing count bytes starting from offset off,
+ * forms a gap at so that off+count is not aligned to atom_size
+ * the end
+ *
+ * head block the first atom affected by an operation, which forms
+ * a gap at the beginning, or(and) at the end.
+ * Сomment. Head block has at least one gap (either at
+ * the beginning, or at the end)
+ *
+ *
+ * tail block the last atom different from head, affected by an
+ * operation, which forms a gap at the end.
+ * Сomment: Tail block has exactly one gap (at the end).
+ *
+ *
+ * partial block head or tail block

+/**
+ * This is the main update routine. Locking has been made granular so as to
+ * maximize parallelism of fops - I'll try to explain it below using execution
+ * timelines.
+ *
+ * Basically, the contention is between multiple execution threads of this
+ * routine and the roll-over thread. So, instead of having a big lock, we hold
+ * granular locks: inode->lock and priv->lock. Now I'll explain what happens
+ * when there is an update and a roll-over at just about the same time.
+ * NOTE:
+ * - the dispatcher itself synchronizes updates via it's own lock
+ * - the slice version in incremented by the roll-over thread
+ *
+ * Case 1: When the rollover thread wins before the inode version can be
+ * compared with the slice version.
+ *
+ * [updater] | [rollover]
+ * |
+ * | <SLICE: 1, 1, 1>
+ * <changelog_update> |
+ * <changelog_inode_ctx_get> |
+ * <CTX: 1, 1, 1> |
+ * | <dispatch-rollover-event>
+ * | LOCK (&priv->lock)
+ * | <SLICE_VERSION_UPDATE>
+ * | <SLICE: 2, 2, 2>
+ * | UNLOCK (&priv->lock)
+ * |
+ * LOCK (&priv->lock) |
+ * <INODE_VERSION_EQUALS_SLICE> |
+ * I: 1 <-> S: 2 |
+ * update: true |

+ * <dispath-update-event> |
+ * <INODE_VERSION_UPDATE> |
+ * LOCK (&inode->lock) |
+ * LOCK (&priv->lock) |
+ * <CTX: 2, 1, 1> |
+ * UNLOCK (&priv->lock) |
+ * UNLOCK (&inode->lock) |
+ *
+ * Therefore, the change gets recorded in the next change (no lost change). If
+ * the slice version was ahead of the inode version (say I:1, S: 2), then
+ * anyway the comparison would result in a update (I: 1, S: 3).
+ *
+ * If the rollover time is too less, then there is another contention when the
+ * updater tries to bring up inode version to the slice version (this is also
+ * the case when the roll-over thread wakes up during INODE_VERSION_UPDATE.

+This is just the very start for a GlusterFS[1] meta-translator that will
+allow translator code to be written in Python. It's based on the standard
+Python embedding (not extending) techniques, plus a dash of the ctypes module.
+The interface is a pretty minimal adaptation of the dispatches and callbacks
+from the C API[2] to Python, as follows:
+
+* Dispatch functions and callbacks must be defined on an "xlator" class
+ derived from gluster.Translator so that they'll be auto-registered with
+ the C translator during initialization.
+
+* For each dispatch or callback function you want to intercept, you define a
+ Python function using the xxx\_fop\_t or xxx\_cbk\_t decorator.
+
+* The arguments for each operation are different, so you'll need to refer to
+ the C API. GlusterFS-specific types are used (though only loc\_t is fully
+ defined so far) and type correctness is enforced by ctypes.
+
+* If you do intercept a dispatch function, it is your responsibility to call
+ xxx\_wind (like STACK\_WIND in the C API but operation-specific) to pass
+ the request to the next translator. If you do not intercept a function, it
+ will default the same way as for C (pass through to the same operation with
+ the same arguments on the first child translator).
+
+* If you intercept a callback function, it is your responsibility to call
+ xxx\_unwind (like STACK\_UNWIND\_STRICT in the C API) to pass the request back
+ to the caller.
+
+So far only the lookup and create operations are handled this way, to support
+the "negative lookup" example. Now that the basic infrastructure is in place,
+adding more functions should be very quick, though with that much boilerplate I
+might pause to write a code generator. I also plan to add structure
+definitions and interfaces for some of the utility functions in libglusterfs
+(especially those having to do with inode and fd context) in the fairly near
+future. Note that you can also use ctypes to get at anything not explicitly
+exposed to Python already.
+
+_If you're coming here because of the Linux Journal article, please note that
+the code has evolved since that was written. The version that matches the
+article is here:_

+-------------------------------------------------------------------------------
+'test.vol' is a simple volfile with the debug-trace Python translator on top
+of a brick. The volfile can be mounted using the following command.
+
+$ glusterfs --debug -f test.vol /path/to/mntpt
+
+If then file operations are performed on the newly mounted file system, log
+output would be printed by the Python translator on the standard output.

-gsycnd, the Gluster Syncdaemon
-==============================
-
-REQUIREMENTS
-------------
-
-_gsyncd_ is a program which can operate either in _master_ or in _slave_ mode.
-Requirements are categorized according to this.
-
-* supported OS is GNU/Linux
-* Python >= 2.5, or 2.4 with Ctypes (see below) (both)
-* OpenSSH >= 4.0 (master) / SSH2 compliant sshd (eg. openssh) (slave)
-* rsync (both)
-* glusterfs with marker support (master); glusterfs (optional on slave)
-* FUSE; for supported versions consult glusterfs
-
-INSTALLATION
-------------
-
-As of now, the supported way of operation is running from the source directory.
-
-If you use Python 2.4.x, you need to install the [Ctypes module](http://python.net/crew/theller/ctypes/).
-
-CONFIGURATION
--------------
-
-gsyncd tunables are a subset of the long command-line options; for listing them,
-type
-
- gsyncd.py --help
-
-and see the long options up to "--config-file". (The leading double dash should be omitted;
-interim underscores and dashes are interchangeable.) The set of options bear some resemblance
-to those of glusterfs and rsync.
-
-The config file format matches the following syntax:
-
- <option1>: <value1>
- <option2>: <value2>
- # comment
-
-By default (unless specified by the option `-c`), gsyncd looks for config file at _conf/gsyncd.conf_
-in the source tree.
-
-USAGE
------
-
-gsyncd is a utilitly for continous mirroring, ie. it mirrors master to slave incrementally.
-Assume we have a gluster volume _pop_ at localhost. We try to set up the following mirrors
-for it with gysncd:
-
-1. _/data/mirror_
-2. local gluster volume _yow_
-3. _/data/far_mirror_ at example.com
-4. gluster volume _moz_ at example.com
-
-The respective gsyncd invocations are (demoing some syntax sugaring):
-
-1.
-
- gsyncd.py gluster://localhost:pop file:///data/mirror
-
- or short form
-
- gsyncd.py :pop /data/mirror
-
-2. `gsyncd :pop :yow`
-3.
-
- gsyncd.py :pop ssh://example.com:/data/far_mirror
-
- or short form
-
- gsyncd.py :pop example.com:/data/far_mirror
-
-4. `gsyncd.py :pop example.com::moz`
-
-gsyncd has to be available on both sides; it's location on the remote side has to be specified
-via the "--remote-gsyncd" option (or "remote-gsyncd" config file parameter). (This option can also be
-used for setting options on the remote side, although the suggested mode of operation is to
-set parameters like log file / pid file in the configuration file.)

+ * The enumerated type here
+ * is used to index two kind
+ * of integer arrays:
+ * - gauges
+ * - counters
+
+ * A counter is used internally,
+ * in getxattr callbacks, to count
+ * the results, categorized as
+ * the enum names suggest. So values
+ * in the counter are always non-negative.
+
+ * Gauges are part of the API.
+ * The caller passes one to the
+ * top-level aggregator function,
+ * cluster_getmarkerattr(). The gauge
+ * defines an evaluation policy for the
+ * counter. That is, at the
+ * end of the aggregation process
+ * the gauge is matched against the
+ * counter, and the policy
+ * represented by the gauge decides
+ * whether to return with success or failure,
+ * and in latter case, what particular failure
+ * case (errno).
+
+ * The rules are the following: for some index i,
+ * - if gauge[i] == 0, no requirement is set
+ * against counter[i];
+ * - if gauge[i] > 0, counter[i] >= gauge[i]
+ * is required;
+ * - if gauge[i] < 0, counter[i] < |gauge[i]|
+ * is required.
+
+ * If the requirement is not met, then i is mapped
+ * to the respective errno (MCNT_ENOENT -> ENOENT),
+ * or in lack of that, EINVAL.
+
+ * Cf. evaluate_marker_results() and marker_idx_errno_map[]
+ * in libxlator.c
+
+ * We provide two default gauges, one inteded for xtime
+ * aggregation, other for volume mark aggregation. The
+ * policies they represent agree with the hard-coded
+ * one prior to gauges. Cf. marker_xtime_default_gauge
+ * and marker_uuid_default_gauge in libxlator.c

-/* dispatch table for VOLUME SET
- * -----------------------------
- *
- * Format of entries:
- *
- * First field is the <key>, for the purpose of looking it up
- * in volume dictionary. Each <key> is of the format "<domain>.<specifier>".
- *
- * Second field is <voltype>.
- *
- * Third field is <option>, if its unset, it's assumed to be
- * the same as <specifier>.
- *
- * Fourth field is <value>. In this context they are used to specify
- * a default. That is, even the volume dict doesn't have a value,
- * we procced as if the default value were set for it.
- *
- * There are two type of entries: basic and special.
- *
- * - Basic entries are the ones where the <option> does _not_ start with
- * the bang! character ('!').
- *
- * In their case, <option> is understood as an option for an xlator of
- * type <voltype>. Their effect is to copy over the volinfo->dict[<key>]
- * value to all graph nodes of type <voltype> (if such a value is set).
- *
- * You are free to add entries of this type, they will become functional
- * just by being present in the table.
- *
- * - Special entries where the <option> starts with the bang!.
- *
- * They are not applied to all graphs during generation, and you cannot
- * extend them in a trivial way which could be just picked up. Better
- * not touch them unless you know what you do.
- *
- * "NODOC" entries are not part of the public interface and are subject
- * to change at any time.

+/* dispatch table for VOLUME SET
+ * -----------------------------
+ *
+ * Format of entries:
+ *
+ * First field is the <key>, for the purpose of looking it up
+ * in volume dictionary. Each <key> is of the format "<domain>.<specifier>".
+ *
+ * Second field is <voltype>.
+ *
+ * Third field is <option>, if its unset, it's assumed to be
+ * the same as <specifier>.
+ *
+ * Fourth field is <value>. In this context they are used to specify
+ * a default. That is, even the volume dict doesn't have a value,
+ * we procced as if the default value were set for it.
+ *
+ * Fifth field is <doctype>, which decides if the option is public and available
+ * in "set help" or not. "NO_DOC" entries are not part of the public interface
+ * and are subject to change at any time. This also decides if an option is
+ * global (apllies to all volumes) or normal (applies to only specified volume).
+ *
+ * Sixth field is <flags>.
+ *
+ * Seventh field is <op-version>.
+ *
+ * Eight field is description of option: If NULL, tried to fetch from
+ * translator code's xlator_options table.
+ *
+ * Nineth field is validation function: If NULL, xlator's option specific
+ * validation will be tried, otherwise tried at glusterd code itself.
+ *
+ * There are two type of entries: basic and special.
+ *
+ * - Basic entries are the ones where the <option> does _not_ start with
+ * the bang! character ('!').
+ *
+ * In their case, <option> is understood as an option for an xlator of
+ * type <voltype>. Their effect is to copy over the volinfo->dict[<key>]
+ * value to all graph nodes of type <voltype> (if such a value is set).
+ *
+ * You are free to add entries of this type, they will become functional
+ * just by being present in the table.
+ *
+ * - Special entries where the <option> starts with the bang!.
+ *
+ * They are not applied to all graphs during generation, and you cannot
+ * extend them in a trivial way which could be just picked up. Better
+ * not touch them unless you know what you do.
+ *
+ *
+ * Another kind of grouping for options, according to visibility:
+ *
+ * - Exported: one which is used in the code. These are characterized by
+ * being used a macro as <key> (of the format VKEY_..., defined in
+ * glusterd-volgen.h
+ *
+ * - Non-exported: the rest; these have string literal <keys>.
+ *
+ * Adhering to this policy, option name changes shall be one-liners.
