2016-11-09perf hists browser: Fix column indentation on --hierarchyNamhyung Kim
When horizontall scrolling is used in hierarchy mode, the the right most column has unnecessary indentation. Actually it's needed only if some of left (overhead) columns were shown.

When horizontal scrolling is used in hierarchy mode, the folded signed disappears at the right most column.

2016-11-09perf hist browser: Fix hierarchy column countsNamhyung Kim
The perf report/top on TUI supports horizontal scrolling using LEFT and RIGHT keys. But it calculate the number of columns incorrectly when hierarchy mode is enabled so that keep pressing RIGHT key can make the output disappeared. In the hierarchy mode, all sort keys are collapsed into a single column, so it needs to be applied when calculating column numbers.

2016-10-13perf top: Fix refreshing hierarchy entries on TUINamhyung Kim
Markus reported that 'perf top --hierarchy' cannot scroll down after refresh. This was because the number of entries are not updated when hierarchy is enabled. Unlike normal report view, hierarchy mode needs to keep its own entry count since it can have non-leaf entries which can expand/collapse.

2016-09-12perf hists browser: Fix event group displayNamhyung Kim
Milian reported that the event group on TUI shows duplicated overhead. This was due to a bug on calculating hpp->buf position. The hpp_advance() was called from __hpp__slsmg_color_printf() on TUI but it's already called from the hpp__call_print_fn macro in __hpp__fmt(). The end result is that the print function returns number of bytes it printed but the buffer advanced twice of the length. This is generally not a problem since it doesn't need to access the buffer again. But with event group, overhead needs to be printed multiple times and hist_entry__snprintf_alignment() tries to fill the space with buffer after it printed. So it (brokenly) showed the last overhead again. The bug was there from the beginning, but I think it's only revealed when the alignment function was added.

2016-08-01perf annotate: Introduce strerror for handling symbol__disassemble() errorsArnaldo Carvalho de Melo
We were just using pr_error() which makes it difficult for non stdio UIs to provide errors using its widgets, as they need to somehow catch what was passed to pr_error().

2016-07-12tools: Introduce str_error_r()Arnaldo Carvalho de Melo
The tools so far have been using the strerror_r() GNU variant, that returns a string, be it the buffer passed or something else. But that, besides being tricky in cases where we expect that the function using strerror_r() returns the error formatted in a provided buffer (we have to check if it returned something else and copy that instead), breaks the build on systems not using glibc, like Alpine Linux, where musl libc is used. So, introduce yet another wrapper, str_error_r(), that has the GNU interface, but uses the portable XSI variant of strerror_r(), so that users rest asured that the provided buffer is used and it is what is returned.

2016-03-30perf hists: Fix determination of a callchain node's childlessnessAndres Freund
The 4b3a3212233a ("perf hists browser: Support flat callchains") commit over-aggressively tried to optimize callchain_node__init_have_children(). That lead to --tui mode not allowing to expand call chain elements if a call chain element had only one parent. That's why --inverted callgraphs looked halfway sane, but plain ones didn't. Revert that individual optimization, it wasn't really related to the rest of the commit.

2016-03-10perf hists browser: Check sort keys before hot key actionsNamhyung Kim
The context menu in TUI hists browser checks corresponding sort keys when creating the menu item. But hotkey actions lacks these checks so it can filter using incorrect info. For example, default sort key of 'perf top' doesn't contain 'comm' or 'pid' sort key so each hist entry's thread info is not reliable. Thus it should prohibit using thread filter on 't' key.

The commit 2eafd410e669 ("perf hists browser: Only 'Zoom into thread' only when sort order has 'pid'") disabled thread filtering in hist browser for the default sort key. However the he->thread is still valid even if 'pid' sort key is not given. Only thing it should not use is the pid (or tid) of the thread. So allow to filter by thread when 'comm' sort key is given and show pid only if 'pid' sort key is given.

The dynamic entries are right-aligned unlike other entries since it usually has numeric value. But for the hierarchy mode, left alignment is more appropriate IMHO. Also trim spaces on the left so that we can easily identify the hierarchy.

2016-02-26perf report: Fix indentation of dynamic entries in hierarchyNamhyung Kim
When dynamic entries are used in the hierarchy mode with multiple events, the output might not be aligned properly. In the hierarchy mode, the each sort column is indented using total number of sort keys. So it keeps track of number of sort keys when adding them. However a dynamic sort key can be added more than once when multiple events have same field names. This results in unnecessarily long indentation in the output. For example perf kmem records following events: $ perf evlist --trace-fields -i perf.data.kmem kmem:kmalloc: trace_fields: call_site,ptr,bytes_req,bytes_alloc,gfp_flags kmem:kmalloc_node: trace_fields: call_site,ptr,bytes_req,bytes_alloc,gfp_flags,node kmem:kfree: trace_fields: call_site,ptr kmem:kmem_cache_alloc: trace_fields: call_site,ptr,bytes_req,bytes_alloc,gfp_flags kmem:kmem_cache_alloc_node: trace_fields: call_site,ptr,bytes_req,bytes_alloc,gfp_flags,node kmem:kmem_cache_free: trace_fields: call_site,ptr kmem:mm_page_alloc: trace_fields: page,order,gfp_flags,migratetype kmem:mm_page_free: trace_fields: page,order As you can see, many field names shared between kmem events. So adding 'ptr' dynamic sort key alone will set nr_sort_keys to 6. And this adds many unnecessary spaces between columns.
