*	LDAP: Decorate the hot paths in the LDAP provider with systemtap probes	Jakub Hrozek	2016-06-10	1	-0/+224
\| \| \| \| \| \| \| \| \| \| \| \| \|	During performance analysis, the LDAP provider and especially its nested group code proved to be the place where we spend the most time during account requests. Therefore, I decorated the LDAP provider with systemtap probes to be able to observe where the time is spent. The code allows passing of search properties (base, filter, ...) from marks to probes. Where applicable, the probes pass on these arguments to functions and build a human-readable string representation. Reviewed-by: Lukáš Slebodník <lslebodn@redhat.com>
*	SYSDB: Add systemtap probes to track sysdb transactions	Jakub Hrozek	2016-06-10	1	-0/+32
	Actually adds marks for sysdb transactions that receive the transaction nesting level as an argument. The nesting is passed on from probes to marks along with a human-friendly description. The transaction commit is decorated with two probes, before and after. This would allow the caller to distinguish between the time we spend in the transaction (which might be important, because if a transaction is active on an ldb context, even the readers are blocked before the transaction completes) and the time we spend commiting the transaction (which is important because that's when the disk writes occur) The probes would be installed into /usr/share/systemtap/tapset on RHEL and Fedora. This is in line with systemtap's paths which are described in detail in "man 7 stappaths". Reviewed-by: Lukáš Slebodník <lslebodn@redhat.com>
