gfapi: revert several patchs that introduced pre/post attrs

2018-09-17T14:26:06+00:00

Reverted the following:
  - 248152767b0599986bbb6bb35fc27197f6be6964
  - 09943beb499617212f2985ca8ea9ecd1ed1b470e
  - d01f7244e9d9f7e3ef84e0ba7b48ef1b1b09d809

The reverts are redone by hand, due to clang format changes
that made using git to revert the changes more tedious.

gfapi: revert "gfapi: return pre/post attributes at callback for glfs api"

2018-09-17T14:26:06+00:00

This reverts commit 384562b294e9a7847403961e878a4daa0fff33eb.

The revert is done manually owing to the clang format changes,
and the 4.1 patch that reverts this fix is used as the source
for the revert.

The 4.1 patch has the commit ID: 98376e0c0a

misc: fix misc. shebangs

2018-09-11T04:25:17+00:00

* One #!/usr/bin/env python and three #!/usr/bin/python were overlooked
  in all the other python fixups. Ugh.

* Two new python files missed the memo about #!/usr/bin/python3.

* One #!/usr/bin/env bash.
  Various distribution packaging policies have strong wording about
  the use of #!/usr/bin/env ...

  Note: this patch does not change the use of #!/usr/bin/env bash in
  the two files extras/{clang-checker.sh,check_goto.pl} as these are
  not included in any packages. (Although I'm not actually sure why
  anyone would ever use '/usr/bin/env {sh,bash}' as I'm not aware of
  any version-specific differences like there are with, e.g., python.)

* One #!/usr/bin/bash.
  On Fedora and CentOS > 6, /bin is a symlink to /usr/bin, so it
  makes little difference. But Debian & Ubuntu still have separate
  /bin and /usr/bin; and sh and bash are in /bin, not /usr/bin.
  (Historically, in BSD and SYSV Unix it was /bin/sh.)

  Note: Fedora and CentOS package build runs a script that converts
  all /bin/sh and /bin/bash to /usr/bin/sh and /usr/bin/bash.

cluster/dht: Rework the debug xattr to get hashed subvol

2018-09-07T08:55:32+00:00

The earlier implementation required the file to already exist
when trying to get the hashed subvol. The reworked implementation
allows a user to get the hashed subvol for any filename, whether
it exists or not.

Usage: getfattr -n "dht.file.hashed-subvol." 

Eg:To get the hashed subvol for file-1 inside dir-1

getfattr -n "dht.file.hashed-subvol.file-1" /mnt/gluster/dir1

io-stats: dump io-stats info in /var/run/gluster

2018-09-05T09:24:52+00:00

It wouldn't make sense to allow iostats file to be written in
*any* directory. While the formating makes sure we try to append
io-stats-name for the file, so overwriting existing file is slim,
but in any case it makes sense to restrict dumping to one directory.

Below are the sample commands, and files created for the corresponding
values:

 $ setfattr -n trusted.io-stats-dump -v file-for-dump $M0

In this case, the file would be in /var/run/gluster/file-for-dump

 $ setfattr -n trusted.io-stats-dump -v /dir1/dir2/file-for-dump $M0

In this case, then the dump file is in /var/run/gluster/dir1-dir2-file-for-dump

Note that the value passed for this virtual xattr would be treated as a
file, and even if the value has '/' in it, it would be changed to '-'
for sanity.

afr: thin-arbiter read txn changes

2018-09-05T08:28:23+00:00

If both data bricks are up, read subvol will be based on read_subvols.

If only one data brick is up:
- First qeury the data-brick that is up. If it blames the other brick,
allow the reads.

- If if doesn't, query the TA to obtain the source of truth.

TODO: See if in-memory state can be maintained for read txns (BZ 1624358).
