protocol/server: Fix client/server compatibility

2016-07-05T11:57:59+00:00

The 3.8 client expects a child_up key from the server
indicating the status of the server translators. This
key is not being sent by the servers running older
versions, thereby breaking compatibility.

With this patch we are treating the absence of the said
key as an indication that the server trying to connect
to this client is running an older version and hence
in such a case we are setting conf->child_up as
_gf_true explicitly. This should suffice in emulating
the older behavior.

Due to the nature of this bug, requiring two version to
be reproducible, there are no testcases added for the same.

protocol: Add framework to send transaction id with recall

2016-06-10T11:03:54+00:00

Backport of: http://review.gluster.org/#/c/14647/

Issue:
The upcall(cache invalidation/recall) event is sent from the bricks
to clients. In AFR/EC setup, it can so happen that all the bricks
will send the upcall for the same event, and if AFR/EC doesn't filter
out these duplicate notifications, the logic above cluster xlators
can fail.

Solution:
Use transaction id to filter out duplicate notifications.

This patch adds framework for duplicate notifications.
AFR/EC can build up on this patch for deduping the notifications

cluster/ec: Use correct log levels

2016-05-30T14:38:00+00:00

Problem :
Misleading messages are getting logged in mount logs
and bricks log.
"Mismatching xdata" and "Heal failed" are getting logged

Solution :
Reduce the level of logs from INFO, WARNING and NOTICE
to DEBUG level wherever applicable OR use fop_log_level
to get proper log level.

core: Honour mandatory lock flags during lock migration

2016-05-27T14:50:37+00:00

lk_flags from posix_lock_t structure is the primary key used to
differentiate locks as either advisory and mandatory type. During
lock migration this field is not read in getactivelk() call path.
So in order to copy the exact lock state from source to destination
it is necessary to include lk_flags within lock_migration_info_t
structure to maintain accurate state. This change also includes
minor modifications to setactivelk() call to consider lk_flags
during lock migration.
