2012-10-31perf browser: Don't show scripts menu for 'perf top'Feng Tang
As 'perf top' has no data files to run scripts against. Also add a is_report_browser() helper function to judge whether the running browser is for 'perf report'.

2012-10-29perf hists browser: Integrate script browser into main hists browserFeng Tang
Integrate the script browser into "perf report" framework, users can use function key 'r' or the drop down menu to list all perf scripts and select one of them, just like they did for the annotation.

2012-10-17perf hists browser: Add back callchain folding symbolArnaldo Carvalho de Melo
The commit 5395a04841fc ("perf hists: Separate overhead and baseline columns") makes the "Overhead" column no more the first one, this caused the test that checks if it is time to show if a histogram entry has callchains never hits. Fix it by checking if the 'i' variable is equal to PERF_HPP__OVERHEAD instead of 0.

2012-10-16perf hists browser: Fix off-by-two bug on the first columnNamhyung Kim
The commit 5395a04841fc ("perf hists: Separate overhead and baseline columns") makes the "Overhead" column no more the first one. So it resulted in the mis-aligned column in the normal (non-diff) output.

2012-10-04perf diff: Removing the total_period argument from output codeJiri Olsa

Removing 'struct perf_hpp::total_period' pointer, because it's no longer needed.

2012-10-04perf tool: Add hpp interface to enable/disable hpp columnJiri Olsa
Adding perf_hpp__column_enable function to enable/disable hists column and removing diff command specific stuff 'need_pair and show_displacement' from hpp code. The diff command now enables/disables columns separately according to the user arguments. This will be helpful in future patches where more columns are added into diff output.

2012-09-14perf hists browser: Fix first column printingNamhyung Kim
As a side effect of commit f5951d56a2ab ("perf hists browser: Use perf_hpp__format functions") perf report TUI got a problem of not refreshing the first character. Since the previous patch restores the column width of "overhead" to 7 we can start at column 0 now.

2012-09-14perf hists browser: Fix output for 100.00%Namhyung Kim
Current hpp format functions assume that the output will fit to 6 character including % sign (XX.YY%) so used "%5.2f%%" as a format string. However it might be the case if collapsing resulted in a single entry which has 100.00% (7 character) of period. In this case the output will be shifted by 1 character.

2012-07-25perf tools: use XSI-complaint version of strerror_r() instead of GNU-specificKirill A. Shutemov
Perf uses GNU-specific version of strerror_r(). The GNU-specific strerror_r() returns a pointer to a string containing the error message. This may be either a pointer to a string that the function stores in buf, or a pointer to some (immutable) static string (in which case buf is unused). In glibc-2.16 GNU version was marked with attribute warn_unused_result. It triggers few warnings in perf: util/target.c: In function ‘perf_target__strerror’: util/target.c:114:13: error: ignoring return value of ‘strerror_r’, declared with attribute warn_unused_result [-Werror=unused-result] ui/browsers/hists.c: In function ‘hist_browser__dump’: ui/browsers/hists.c:981:13: error: ignoring return value of ‘strerror_r’, declared with attribute warn_unused_result [-Werror=unused-result] They are bugs.

2012-06-19perf hists browser: Implement printing snapshots to filesArnaldo Carvalho de Melo
To avoid having to resort to --stdio, that expands everything, instead allow the user to go on expanding the relevant callchains and then press 'P' to print that view. As the hists browser is used for both static (report) and dynamic (top) views, it prints to a 'perf.hists.N' sequence, i.e. multiple snapshots can be taken in report and top.
