* Further fixes and eye candy.Gravatar David Garcia Quintas2015-05-06
| | | | | In particular, fixed the handling of } when nesting gets complex. Made the reporting of block percentiles consistent with the ! reporting.
* Handling of ! tags across threads & performance.Gravatar David Garcia Quintas2015-05-06
| | | | | | | | Fixed an important bug whereby thread info wasn't being taken into account for ! marks. Also dramatically improved performance by getting rid of a silly O(n^2) loop.
* Avoid repeated sortings in percentile() calls.Gravatar David Garcia Quintas2015-05-06
| | | | Have the function expect sorted input.
* Implemented aggregation over important mark times.Gravatar David Garcia Quintas2015-05-06
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Namely, 50,90,95 and 99th percentiles are now reported on important marks. Example output (for a single ! mark between begin-end marks in grpc_tcp_write()): ``` Important marks: ================ 99999@src/core/iomgr/tcp_posix.c:545 Relative mark: 50th p. 90th p. 95th p. 99th p. 205 { (src/core/iomgr/tcp_posix.c:541): 0.037 0.057 0.070 0.087 205 } (src/core/iomgr/tcp_posix.c:556): 15.181 27.021 32.509 41.103 ``` For a fabricated example (see https://gist.github.com/dgquintas/026d333815589cc37269) with the same ! mark in two different frames, the output is: ``` Important marks: ================ 999999@src/core/iomgr/tcp_posix.c:5 Relative mark: 50th p. 90th p. 95th p. 99th p. 205 { (src/core/iomgr/tcp_posix.c:1): 9.500 13.900 14.450 14.890 205 } (src/core/iomgr/tcp_posix.c:6): 3.000 4.600 4.800 4.960 999999@src/core/iomgr/tcp_posix.c:3 Relative mark: 50th p. 90th p. 95th p. 99th p. 205 { (src/core/iomgr/tcp_posix.c:1): 2.500 2.900 2.950 2.990 205 { (src/core/iomgr/tcp_posix.c:2): 1.500 1.900 1.950 1.990 205 } (src/core/iomgr/tcp_posix.c:4): 2.000 2.800 2.900 2.980 205 } (src/core/iomgr/tcp_posix.c:6): 10.000 15.600 16.300 16.860 ```
