Problem: At the time of stopping the volume while brick multiplex is
enabled memory is not cleanup from all server side xlators.
Solution: To cleanup memory for all server side xlators call fini
in glusterfs_handle_terminate after send GF_EVENT_CLEANUP
notification to top xlator.
BUG: 1544090
Signed-off-by: Mohit Agrawal <moagrawa@redhat.com>
Note: Run all test-cases in separate build (https://review.gluster.org/19574)
with same patch after enable brick mux forcefully, all test cases are
passed.

There are still remain some code paths where cleanup is required while
brick mux is on.I will upload a new patch after resolve all code paths.
This reverts commit b313d97faa766443a7f8128b6e19f3d2f1b267dd.

This patch creates a new way of defining message id's that is easier
and less error prone because it doesn't require so many manual changes
each time a new component is defined or a new message created.

Problem: Sometime brick process is getting crash in notify function at the
time of cleanup db connection while brick mux is enabled.
Solution: In changetimerrecorder (ctr) notify function after cleanup
db connection set to db_conn to NULL to avoid reuse the same
db connection again.
Note: Below is the backtrace pattern showing by brick process

stopped any volume
Problem: After enabled brick mux if any volume has down and then try ot run mount
with running volume , mount command is hung.
Solution: After enable brick mux server has shared one data structure server_conf
for all associated subvolumes.After down any subvolume in some
ungraceful manner (remove brick directory) posix xlator sends
GF_EVENT_CHILD_DOWN event to parent xlatros and server notify
updates the child_up to false in server_conf.When client is trying
to communicate with server through mount it checks conf->child_up
and it is FALSE so it throws message "translator are not yet ready".
From this patch updated structure server_conf to save child_up status
for xlator wise. Another improtant correction from this patch is
cleanup threads from server side xlators after stop the volume.

Demote files on priority if hi-watermark has been breached and continue
to demote until the watermark drops below hi-watermark.
Monitor watermark more frequently.
Trigger demotion as soon as hi-watermark is breached.
Add cluster.tier-emergency-demote-query-limit option to limit number
of files returned from the database query for every iteration of
tier_migrate_using_query_file(). If watermark hasn't dropped below
hi-watermark during the first iteration, the next iteration will be
triggered approximately 1 second after tier_demote() returns to the
main tiering loop.
Update changetimerecorder xlator to handle query for emergency demote
mode.
Add tier-ctr-interface.h:
Move tier and ctr interface specific macros and struct definition from
libglusterfs/src/gfdb/gfdb_data_store.h to new header
libglusterfs/src/tier-ctr-interface.h

And minor cleanup of a few of the Makefile.am files while we're
at it.
Rewrite the make rules to do what xdrgen does. Now we can get rid
of xdrgen.
Note 1. netbsd6's sed doesn't do -i. Why are we still running
smoke tests on netbsd6 and not netbsd7? We barely support netbsd7
as it is.
Note 2. Why is/was libgfxdr.so (.../rpc/xdr/src/...) linked with
libglusterfs? A cut-and-paste mistake? It has no references to
symbols in libglusterfs.
Note3. "/#ifndef\|#define\|#endif/" (note the '\'s) is a _basic_
regex that matches the same lines as the _extended_ regex
"/#(ifndef|define|endif)/". To match the extended regex sed needs to
be run with -r on Linux; with -E on *BSD. However NetBSD's and
FreeBSD's sed helpfully also provide -r for compatibility. Using a
basic regex avoids having to use a kludge in order to run sed with
the correct option on OS X.
Note 4. Not copying the bit of xdrgen that inserts copyright/license
boilerplate. AFAIK it's silly to pretend that machine generated
files like these can be copyrighted or need license boilerplate.
The XDR source files have their own copyright and license; and
their copyrights are bound to be more up to date than old
boilerplate inserted by a script. From what I've seen of other
Open Source projects -- e.g. gcc and its C parser files generated
by yacc and lex -- IIRC they don't bother to add copyright/license
boilerplate to their generated files.
It appears that it's a long-standing feature of make (SysV, BSD,
gnu) for out-of-tree builds to helpfully pretend that the source
files it can find in the VPATH "exist" as if they are in the $cwd.
rpcgen doesn't work well in this situation and generates files
with "bad" #include directives.
E.g. if you `rpcgen ../../../../$srcdir/rpc/xdr/src/glusterfs3-xdr.x`,
you get an #include directive in the generated .c file like this:
...
#include "../../../../$srcdir/rpc/xdr/src/glusterfs3-xdr.h"
...
which (obviously) results in compile errors on out-of-tree build
because the (generated) header file doesn't exist at that location.
Compared to `rpcgen ./glusterfs3-xdr.x` where you get:
...
#include "glusterfs3-xdr.h"
...
Which is what we need. We have to resort to some Stupid Make Tricks
like the addition of various .PHONY targets to work around the VPATH
"help".
Warning: When doing an in-tree build, -I$(top_builddir)/rpc/xdr/...
looks exactly like -I$(top_srcdir)/rpc/xdr/... Don't be fooled though.
And don't delete the -I$(top_builddir)/rpc/xdr/... bits

Problem: As metadata in the database fills up, querying the database
take a long time. As a result, tier migration slows down. To
counteract this, we added a way to enable the compaction methods of
the underlying database. The goal is to reduce the size of the
underlying file by eliminating database fragmentation.
NOTE: There is currently a bug where sometimes a brick will
attempt to activate compaction. This happens even compaction is already
turned on.
The cause is narrowed down to the compact_mode_switch flipping its value.
Changes: libglusterfs/src/gfdb - Added a gfdb function to compact the
underlying database, compact_db() This is a no-op if the database has
no such option.
- Added a compaction function for SQLite3 that does the following
1) Changes the auto_vacuum pragma of the database
2) Compacts the database according to the type of compaction requested
- Compaction type can be changed by changing the macro
GF_SQL_COMPACT_DEF to one of the 4 compaction types in
gfdb_sqlite3.h
It is currently set to GF_SQL_COMPACT_INCR, or incremental
vacuuming.
xlators/cluster/dht/src - Added the following command-line option to
enable SQLite3 compaction.
gluster volume set <vol-name> tier-compact <off|on>
- Added the following command-line option to change the frequency the
hot and cold tier are ordered to compact.
gluster volume set <vol-name> tier-hot-compact-frequency <int>
gluster volume set <vol-name> tier-cold-compact-frequency <int>
- tier daemon periodically sends the (new)
GFDB_IPC_CTR_SET_COMPACT_PRAGMA IPC to the CTR xlator. The IPC
triggers compaction of the database.
The inputs are both gf_boolean_t.
IPC Input:
compact_active: Is compaction currently on for the db.
compact_mode_switched: Did we flip the compaction switch recently?
IPC Output:
0 if the compaction succeeds.
Non-zero otherwise.
xlators/features/changetimerecorder/src/ - When the CTR gets the
compaction IPC, it launches a thread that will perform the
compaction. The IPC ends after the thread is launched. To avoid extra
allocations, the parameters are passed using static variables.

This is a defensive fix to prevent a crash reported
during a rename operation. This is not reproducible
under normal circumstances.
This patch also moves ctr-messages.h to the src dir
of the changetimerecorder xlator.

According to [1], the -module option must appear in the Makefile.am
file(s); if -module is defined in a macro, e.g. in configure(.ac),
then libtool will not recognize that this is a module and will emit a
warning.

Problem: When a file with old_file_name and GFID_1 is renamed with a new_file_name
which already exists and with GFID_2, this is what happens in linux internaly.
a. "new_file_name" is unlinked for GFID_2
b. a hardlink "new_file_name" is created to GFID_1
c. "old_file_name" hardlink is unlinked for GFID_2.
Well this is all internal to linux, and gluster just issues a rename system call
at POSIX layer. But CTR Xlator doesn't delete the entries corresponding to the
"new_file_name" and GFID_2. Thus leaving the stale entry in the DB.
The following are the implications.
a. Promotion are tried on these stale entries which will fail and show
false results in the status of migration,
b. GFID_2 Files with 2 hardlinks, which will have only one hardlink
after the rename will not be promoted or demoted as the DB shows 2 entries.
Solution: Delete the older database entry for the replaced hardlink

various xlators and other components are invoking system calls

If not using the system call wrappers there should be a comment

Currently we heat up a file for both data and metadata write.
Here we provide a ctr xlator option called "ctr-record-metadata-heat"
were the admin can decide on recording metadata heat i.e heatup a
file on metadata writes or not.
Metadata data operation are
a. setattr: explicit changing of atime/mtime using utimes,
changing of posix permissions of the file
b. rename: Renaming a file,
c. unlink, link: adding or deleting hardlinks
d. xattrs: setting or removal of xattrs.
NOTE: atime, mtime and ctime change through writev, readv, truncate, mknod
and create will not be considered here as these fops are data and primary
metadata fops.
Defaultly "ctr-record-metadata-heat" is off. Admin can
switch it on using gluster volume set command.

Earlier, when the database was queried we used to save
all the queried records in an ASCII format in the query file.
This caused issues like filename having ASCII delimiter and used
to take a lot of space. The tier.c file also had a lot of parsing code.
Here we changed the format of the query file to binary.
All the logic of serialization and formating of query record is done
by libgfdb. Libgfdb provides API,
gfdb_write_query_record() and gfdb_read_query_record(),
which the user i.e tier migrator and CTR xlator can use to
write to and read from query file.
With this binary format we save on disk space i.e reduce to 50% atleast
as we are saving GFID's in binary format 16 bytes and not the string format
which takes 36 bytes + We are not saving path of the file + we are also saving on
ASCII delimiters.
The on disk format of query record is as follows,
+---------------------------------------------------------------------------+
| Length of serialized query record | Serialized Query Record |
+---------------------------------------------------------------------------+
4 bytes Length of serialized query record
|
|
-------------------------------------------------|
|
|
V
Serialized Query Record Format:
+---------------------------------------------------------------------------+
| GFID | Link count | <LINK INFO> |..... | FOOTER |
+---------------------------------------------------------------------------+
16 B 4 B Link Length 4 B
| |
| |
-----------------------------| |
| |
| |
V |
Each <Link Info> will be serialized as |
+-----------------------------------------------+ |
| PGID | BASE_NAME_LENGTH | BASE_NAME | |
+-----------------------------------------------+ |
16 B 4 B BASE_NAME_LENGTH |
|
|
------------------------------------------------------------------------|
|
|
V
FOOTER is a magic number 0xBAADF00D indicating the end of the record.
This also serves as a serialized schema validator.

Heal hardlink in the db for already existing data in the cold
tier during attach tier. i.e during fix layout do lookup to files
in the cold tier.
CTR xlator on the brick/server side does db update/insert of the hardlink on a namelookup.
Currently the namedlookup is done synchronous to the fixlayout that is
triggered by attach tier. This is not performant, adding more time to
fixlayout. The performant approach is record the hardlinks on a compressed
datastore and then do the namelookup asynchronously later, giving the ctr db
eventual consistency

version less than 3.7 i.e rhel 6.7
Problem: On RHEL 6.7, we have sqlite version 3.6.2 which doesnt support
WAL journaling mode, as this journaling mode is only available in sqlite 3.7 and above.
As a result we cannot have to progreses concurrently accessing sqlite, without
running into db locks! Well WAL is also need for performace on CTR side.
Solution: This solution is to use CTR db connection for doing queries when WAL mode is
absent. i,e tier migrator will send sync_op ipc calls to CTR, which in turn will
do the query and create/update the query file suggested by tier migrator.
Pending: Well this solution will stop the db locks but the performance is still an issue for CTR.
We are developing an in-Memory Transaction Log (iMeTaL) which will help boost the CTR
performance by doing in memory udpates on the IO path and later flush the updates to
the db in a batch/segment flush.

We've been lucky that we haven't had any symbol collisions until now.
Now we have a collision between the snapview-client's svc_lookup() and
libntirpc's svc_lookup() with nfs-ganesha's FSAL_GLUSTER and libgfapi.
As a short term solution all the snapview-client's FOP methods were
changed to static scope. See http://review.gluster.org/11805. This
works in snapview-client because all the FOP methods are defined in
a single source file. This solution doesn't work for other xlators
with FOP methods defined in multiple source files.
To address this we link with libtool's '-export-symbols $symbol-file'
(a wrapper around `ld --version-script ...` --- on linux anyway) and
only export the minimum required symbols from the xlator sharedlib.
N.B. the libtool man page says that the symbol file should be named
foo.sym, thus the rename of *.exports to *.sym. While foo.exports
worked, we will follow the documentation.

Problem: The DB on the brick is been accessed by CTR, for write and
tier migrator, for read and write. The write from tier migrator is reseting
the heat counters after a cycle. Since we are using sqlite, two connections
trying to write would cause a db lock contention. As a result CTR used to fail
to update the db.
Solution: Using the same db connection of CTR for reseting the heat counters.
1) Introducted a new IPC FOP for CTR
2) After the query do a ipc syncop to the underlying client xlator associated
to the brick.
3) CTR in brick will catch the IPC FOP and cleat the heat counters.

There are three kinds of inline functions: plain inline, extern inline,
and static inline. All three have been removed from .c files, except
those in "contrib" which aren't our problem. Inlines in .h files, which
are overwhelmingly "static inline" already, have generally been left
alone. Over time we should be able to "lower" these into .c files, but
that has to be done in a case-by-case fashion requiring more manual
effort. This part was easy to do automatically without (as far as I can
tell) any ill effect.
In the process, several pieces of dead code were flagged by the
compiler, and were removed.

in ctr_lookup, the loc variable need not be comes with pargfid,
though there is a parent for the inode. The same for loc->name
also. From this patch, we will generate loc->name from loc->path

Since by default CTR translator is disabled, the following
log message is being displayed in brick logs.
[ctr-helper.c:256:extract_ctr_options] 0-gfdbdatastore: CTR Xlator is disabled.
Therefore this change is to reduce the log-level to INFO.

2) Ignore lookup for T file in ctr_lookup
3) Ctr_lookup:
a. If the gfid and pgfid in empty dont record
b. Decreased log level for multiple heal attempts
c. Inode/File heal happens after an expiry period, which is configurable.
d. Hardlink heal happens after an expiry period, which is configurable.

Instead of including config.h in each file, and have the additional
config.h included from the compiler commandline (-include option).
When a .c file tests for a certain #define, and config.h was not
included, incorrect assumtions were made. With this change, it can not
happen again.

Problem: The CTR xlator records file meta (heat/hardlinks)
into the data. This works fine for files which are created
after ctr xlator is switched ON. But for files which were
created before CTR xlator is ON, CTR xlator is not able to
record either of the meta i.e heat or hardlinks. Thus making
those files immune to promotions/demotions.
Solution: The solution that is implemented in this patch is
do ctr-db heal of all those pre-existent files, using named lookup.
For this purpose we use the inode-xlator context variable option
in gluster.
The inode-xlator context variable for ctr xlator will have the
following,
a. A Lock for the context variable
b. A hardlink list: This list represents the successful looked
up hardlinks.
These are the scenarios when the hardlink list is updated:
1) Named-Lookup: Whenever a named lookup happens on a file, in the
wind path we copy all required hardlink and inode information to
ctr_db_record structure, which resides in the frame->local variable.
We dont update the database in wind. During the unwind, we read the
information from the ctr_db_record and ,
Check if the inode context variable is created, if not we create it.
Check if the hard link is there in the hardlink list.
If its not there we add it to the list and send a update to the
database using libgfdb.
Please note: The database transaction can fail(and we ignore) as there
already might be a record in the db. This update to the db is to heal
if its not there.
If its there in the list we ignore it.
2) Inode Forget: Whenever an inode forget hits we clear the hardlink list in
the inode context variable and delete the inode context variable.
Please note: An inode forget may happen for two reason,
a. when the inode is delete.
b. the in-memory inode is evicted from the inode table due to cache limits.
3) create: whenever a create happens we create the inode context variable and
add the hardlink. The database updation is done as usual by ctr.
4) link: whenever a hardlink is created for the inode, we create the inode context
variable, if not present, and add the hardlink to the list.
5) unlink: whenever a unlink happens we delete the hardlink from the list.
6) mknod: same as create.
7) rename: whenever a rename happens we update the hardlink in list. if the hardlink
was not present for updation, we add the hardlink to the list.
What is pending:
1) This solution will only work for named lookups.
2) We dont track afr-self-heal/dht-rebalancer traffic for healing.

1) ctr_link_consistency option for ctr xaltor is provided so that
the user can choose to switch it on or off.
/* For link consistency we do a double update i.e mark the link
* during the wind and during the unwind we update/delete the link.
* This has a performance hit. We give a choice here whether we need
* link consistency to be spoton or not using link_consistency flag.
* This will have only one link update */
2) In delete the wind time recording is moved to unwind path.
/* Special performance case:
* Updating wind time in unwind for delete. This is done here
* as in the wind path we will not know whether its the last
* link or not. For a last link there is not use to update any
* wind or unwind time!*/

This implementation is same as the posix_unlink_cbk() where CTR sends
a request during a unlink to send the number of links to the inode
and posix obliges sending it using the unwind xdata dict.
For Trash xlator a unlink is stat + mkdir(if parent is not present)
+ rename. And hence this is handled in trash_unlink_rename_cbk().

This fix will solve the heating of the files during the promotion
or demotion.
Promotion:
~~~~~~~~~
When a file gets promoted it get the current time stamp
during creation only, but following writes or reads during the
migration wont heat the file.
Demotion:
~~~~~~~~
When a file gets demoted it get the wind/unwind time stamp is set to
zero. The following writes or reads during the migration wont heat
the file.
What is remaining ?
~~~~~~~~~~~~~~~~~
Bug 1209129 ( https://bugzilla.redhat.com/show_bug.cgi?id=1209129 )
Inspite of this fix there is still a issue remaining, i.e the heat of
the file is not keep intact during a internal rebalance activity i.e
a rebalance within a tier.

This patch resolves tiering translator issues taken from the list
in bug 1203776. These issues have been selected to be fixed
first. The rest will be fixed in a subsequent patch (or are not a
problem).
3. Replace hardcoded #defines of promote/demote file names
6. Use loc_wipe() in migrate_using_query_file()
9. Only promote/demote files on the same node on which they reside.
14. Replace calloc with GF_CALLOC in tier.c and ensure freeing done
properly.
15. Handle if parse_query_str fails
22. Only load gfdb library on server side, remove SQL references
from client.
