Description Shyamsundar 2018-10-05 14:48:17 UTC
+++ This bug was initially created as a clone of Bug #1636502 +++

Description of problem:

Run a test that needs self heal (say bring down a brick, touch 10 files in others and bring the brick back up online). The self heal logs are filled with the following log message,

[dict.c:2775:dict_get_str_boolean] (-->/usr/local/lib/glusterfs/6dev/xlator/protocol/client.so(+0x6d6c0) [0x7f3bc5ad76c0] -->/usr/local/lib/glusterfs/6dev/xlator/cluster/replicate.so(+0x489ff) [0x7f3bc581d9ff] -->/usr/local/lib/libglusterfs.so.0(dict_get_str_boolean+0xcf) [0x7f3bd3f0c81f] ) 0-dict: key buf-has-zeroes, integer type asked, has unsigned integer type [Invalid argument]

NOTE: Line numbers may be off depending on which commit in master I tested with

This is being generated as, POSIX is encoding a uint32 in the dict for buf-has-zeroes" and AFR is reading a boolean, from code inspection as below,

afr-self-heal-data.c -> __checksum_cbk -> dict_get_str_boolean(xdata, "buf-has-zeroes" ...

posix-inode-fd-ops.c -> posix_rchecksum -> dict_set_uint32(rsp_xdata, "buf-has-zeroes"

The correction needs type safety, and hence the bug.

This issue only existed in master, and the log cleanup patches takes care of the same. This was incorrectly cloned against release-5.
