all: remove code which is not being considered in build
These xlators are now removed from build as per discussion/announcement
done at https://lists.gluster.org/pipermail/gluster-users/2018-July/034400.html
* move rot-13 to playground, as it is used only as demo
purpose, and is documented in many places.
* Removed code of below xlators:
- cluster/stripe
- cluster/tier
- features/changetimerecorder
- features/glupy
- performance/symlink-cache
- encryption/crypt
- storage/bd
- experimental/posix2
- experimental/dht2
- experimental/fdl
- experimental/jbr

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 don't 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 don't track afr-self-heal/dht-rebalancer traffic for healing. - -*/ - -/* This function does not write anything to the db, - * just created the local variable - * for the frame and sets values for the ctr_db_record */ -static int -ctr_lookup_wind(call_frame_t *frame, xlator_t *this, - gf_ctr_inode_context_t *ctr_inode_cx) -{ - int ret = -1; - gf_ctr_private_t *_priv = NULL; - gf_ctr_local_t *ctr_local = NULL; - - GF_ASSERT(frame); - GF_ASSERT(frame->root); - GF_ASSERT(this); - IS_CTR_INODE_CX_SANE(ctr_inode_cx); - - _priv = this->private; - GF_ASSERT(_priv); - - if (_priv->ctr_record_wind && ctr_inode_cx->ia_type != IA_IFDIR) { - frame->local = init_ctr_local_t(this); - if (!frame->local) { - gf_msg(this->name, GF_LOG_ERROR, 0, - CTR_MSG_CREATE_CTR_LOCAL_ERROR_WIND, - "WIND: Error while creating ctr local"); - goto out; - }; - ctr_local = frame->local; - /*Definitely no internal fops will reach here*/ - ctr_local->is_internal_fop = _gf_false; - /*Don't record counters*/ - CTR_DB_REC(ctr_local).do_record_counters = _gf_false; - /*Don't record time at all*/ - CTR_DB_REC(ctr_local).do_record_times = _gf_false; - - /* Copy gfid into db record*/ - gf_uuid_copy(CTR_DB_REC(ctr_local).gfid, *(ctr_inode_cx->gfid)); - - /* Set fop_path and fop_type, required by libgfdb to make - * decision while inserting the record */ - CTR_DB_REC(ctr_local).gfdb_fop_path = ctr_inode_cx->fop_path; - CTR_DB_REC(ctr_local).gfdb_fop_type = ctr_inode_cx->fop_type; - - /* Copy hard link info*/ - gf_uuid_copy(CTR_DB_REC(ctr_local).pargfid, - *((NEW_LINK_CX(ctr_inode_cx))->pargfid)); - if (snprintf(CTR_DB_REC(ctr_local).file_name, - sizeof(CTR_DB_REC(ctr_local).file_name), "%s", - NEW_LINK_CX(ctr_inode_cx)->basename) >= - sizeof(CTR_DB_REC(ctr_local).file_name)) { - gf_msg(this->name, GF_LOG_ERROR, 0, - CTR_MSG_CREATE_CTR_LOCAL_ERROR_WIND, - "WIND: Error copying filename of ctr local"); - goto out; - } - /* Since we are in lookup we can ignore errors while - * Inserting in the DB, because there may be many - * to write to the DB attempts for healing. - * We don't want to log all failed attempts and - * bloat the log*/ - ctr_local->gfdb_db_record.ignore_errors = _gf_true; - } - - ret = 0; - -out: - - if (ret) { - free_ctr_local(ctr_local); - frame->local = NULL; - } - - return ret; -} - -/* This function inserts the ctr_db_record populated by ctr_lookup_wind - * in to the db.
