* ctime: Provide noatime optionKotresh HR2018-10-028-9/+123
| | | | | | | | | | | | | | | | | | | | | | | | Most of the applications are {c|m}time dependant and very few are atime dependant. So provide noatime option to not update atime when ctime feature is enabled. Also this option has to be enabled with ctime feature to avoid unnecessary self heal. Since AFR/EC reads data from single subvolume, atime is only updated in one subvolume triggering self heal.

* misc: fix misc. shebangsKaleb S. KEITHLEY2018-09-112-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * 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.

* ctime: Fix self heal of symlink in EC volumeKotresh HR2018-06-204-4/+2
| | | | | | | | | | | | | | | | | | | | Since IEEE Std 1003.1-2001 does not require any association of file times with symbolic links, there is no requirement that file times be updated by readlink() states [1]. stat on symlink file was generating a readlink fop on one of the subvolumes of ec set which in turn updates atime on that subvolume. This causes mdata xattr to be different across ec set and hence self heal fails. So based on [1], atime is no longer updated by readlink fop.

* build: Disallow unresolved symbol referencesPrashanth Pai2018-05-181-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | In the past, it was often[1] forgotten for xlators to be linked against the symbols they refer to. This often caused glusterd2 to fail while loading xlator's shared object (.so) file. This change adds "--no-undefined" as a linker flag which causes the linker to treat unresolved symbol references as an error and hence fail linking.

* utime: ctime client side xlatorKotresh HR2018-05-0610-0/+611
The client side utime xlator does two things. 1. Update unix epoch time in frame->root->ctime 2. Update the frame->root->flags based on the fop which indicates time attributes that should be updated for the parent/entry.
