When the --hierarchy option is used, each entry has its own hpp_list to
show the result. But it is not updating the width of each column for
perf-top. The perf-report command has no problem since it resets it
during header display.
$ sudo perf top --hierarchy --stdio
PerfTop: 160 irqs/sec kernel:38.8% exact: 100.0%
[4000Hz cycles:pp], (all, 12 CPUs)

Move the code into hists__fprintf() so that it can be called always.

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.

to provide errors using its widgets, as they need to somehow catch what

This is just the initial step, more work will be done, but first some

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.

The 4b3a321223 ("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.

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 2eafd410e6 ("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 nr_sort_keys field is to carry the number of sort entries in a
hpp_list or hists to determine the depth of indentation of a hist entry.
As it's only used in hierarchy mode and now we have used nr_hpp_node for
this reason, there's no need to keep it anymore. Let's get rid of it.

into a file so it needs to be sync-ed with the corresponding function
hist_browser__show_hierarchy_entry(). So use hists->nr_hpp_node to

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.

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.

The dynamic entry is created for each field in a tracepoint event.
Since they have no fixed hpp format index, it should skip when
perf_hpp__reset_width() is called.
This caused following assertion failure..

We were doing column alignment in the format function for each cell,
returning a string padded with spaces so that when the next column is
printed the cursor is at its column alignment.
This ends up needlessly printing trailing spaces, do it at the format
iterator, that is where we know if it is needed, i.e. if there is more
columns to be printed.
This eliminates the need for triming lines when doing a dump using 'P'
in the TUI browser and also produces far saner results with things like
piping 'perf report' to 'less'.
Right now only the formatters for sym->name and the 'locked' column
(perf mem report), that are the ones that end up at the end of lines
in the default 'perf report', 'perf top' and 'perf mem report' tools,
the others will be done in a subsequent patch.
In the end the 'width' parameter for the formatters now mean, in
'printf' terms, the 'precision', where before it was the field 'width'.

When there's only a single callchain, perf doesn't print its percentage
in front of the symbols. This is because it assumes that the percentage
is same as parents. But if a percent limit is applied, it's possible
that there are actually a couple of child nodes but only one of them is
shown. In this case it should display the percent to prevent
misunderstanding of its percentage is same as the parent's.
For example, let's see the following callchain.
$ perf report --no-children --percent-limit 0.01 --tui
...
- 0.06% sleep [kernel.vmlinux] [k] kmem_cache_alloc_trace
kmem_cache_alloc_trace
- perf_event_mmap
- 0.04% mmap_region
do_mmap_pgoff
- vm_mmap_pgoff
+ 0.02% sys_mmap_pgoff
+ 0.02% vm_mmap
+ 0.02% mprotect_fixup
Current code omits the percent if 'mmap_region' becomes the only node
when percent limit is set to 0.03%, its percent is not 0.06% but users
will assume it incorrectly.
Before:
$ perf report --no-children --percent-limit 0.03 --tui
...

- perf_event_mmap
