Subject: [PATCH v3 4/4] Make all print functions receive the fp argument, open and close the dump_event file for each evsel, and calculate the dump_event file's size.
From: yuzhoujian <yuzhoujian@...ichuxing.com>
This patch will make all print functions receive the fp, add the fp_selection_helper
function to select the fp(stdout or the dump_event fp) and open the dump file for
all print functions. When the perf script is over, closes the dump_event file and
calculate its size.
Changes since v2:
- remove the file_name variable and get the data file name from struct perf_session
- remove the per_event_dump_file variable and get the dump_event fp from struct
perf_evsel
- add the fp_selection_helper function to select the fp(stdout or the dump_event
fp) and open the dump file for all print functions if evname and last evsel name is not
the same.
- close the dump file for all the evsels and calculate the dump file's size at the end of
the perf script.
- solve the segmentation fault generated by perf script --per-event-dump --show-mmap-events
Changes since v1:
- modify the dump file name to <ORIGINAL PERF DATA FILE NAME>-script-dump-<EVENT NAME>.txt
ect. perf.data-script-dump-cycles.txt, perf.data-script-dump-cs.txt
- split the original patch(Make all those related functions receive the file pointer)
to two patches, and this is the second part of the original one.
