Ingo suggested that I factor out the perf subcommand functionality
(originally copied from git) into tools/lib so that it can be used by
stacktool[*] and possibly others.
All the subcommand option handling files have been moved into libapi,
including parse-options.c, run-command.c, exec_cmd.c, help.c, usage.c,
and their dependencies. Since several of the dependencies are more
general-purpose "utilities" which aren't directly related to
subcommands, I put everything in 'tools/lib/api/util'. They're linked
into perf as part of the libapi.a library.
Patches 1-13 do some cleanups and splitting up of the code in
preparation for the move.
Patch 14 does the actual moving of the files into tools/lib/api/util.
Based on tip/perf/core.

If there's a local header file which has the same name as a system
header file, '#include <header.h>' will mistakenly include the local
file instead of the system file.
With the next patch we'll have a string.h file. Use the '-iquote'
option to prepare for it so that '#include "string.h"' picks up the
local version.
Note that after applying this patch, a 'make clean' is needed to clear
out the old versions of tools/perf/tests/llvm-src-*.c.

util.h is a hodgepodge which consists of:
1) some compatibility macros and system includes
2) declarations for util.c
3) declarations for other .c files
Move the compatibility macros and system includes to compat-util.h.
Move the declarations for other .c files to their respective proper
locations, creating new header files where needed.
This makes the code better organized and will make it easier to untangle
these pieces into separate components later.

The term functions are needed by help.c which is going to be moved into
a separate library. Move them out of util.c and into their own file.

cache.h is a hodgepodge which consists of:
1) some macros
2) some includes
3) declarations for other .c files
Move the macros and declarations to more appropriate places. This makes
the code more organized and makes it easier to separate out the
components later. Some of the components will be moved out of perf into
a separate library.

cache.h is now just a collection of some commonly used includes. Move
the includes to util.h, which has a similar collection.

perf_env__set_cmdline() only saves the arguments the first time it's
called. It doesn't need to be called every time the options and
suboptions are parsed. Instead it can just be called once.
This also has the advantage of making the option parsing code less
perf-specific so it can be moved out to a library.

PERF_PAGER_IN_USE doesn't seem to be used anywhere, so let's remove it.
This will also make it easier to move pager.c into a separate library.

help_unknown_cmd() is quite perf-specific because it relies on some
perf_config*() functions. Move it and its supporting functions out into
a separate file so that help.c can be moved to a library.

Get rid of libstring and move tools/lib/string.c to libapi where it can
more easily be used by other tools.

The perf subcommand framework is needed for other tools. Move
parse-options.c and its dependencies over to libapi.
Any function names with 'perf' have been renamed to something more
generic.
Also created a util_cfg struct for passing perf-specific configuration
to the library. Specifying the configuration at runtime allows the same
binary to be shared by multiple tools without having to recompile it.

I'm certainly open to doing so, but I'm having trouble coming up with a
better name. The current name makes sense to me, because the struct
contains various configuration options needed by the libapi "util" code.
Would 'libapi_util_config' be better? Or do you have any other
suggestions?

Please break it up into multiple pieces, as suggested by Jiri, in doing
so you may find some better name.
But since several are related to command environment setup, perhaps
'struct cmd_exec_env'?

IMO, 'struct cmd_exec_env' doesn't describe the struct accurately. I
think it tangentially describes some features of some of the fields, but
not all of them. That seems more confusing to me.
Is your complaint that the name is too vague? If so, that's actually by
design, because the struct is meant to be a generic interface for
providing various unrelated configuration variables to libapi.
I've split the patch up into the above 3 paragraphs as Jiri suggested.
But I still don't have any ideas for a name better than 'util_cfg'
(other than something more verbose like 'libapi_util_config').
Instead of a single struct, we could consider splitting it into multiple
structs (e.g., one for exec_cmd.c, one for parse-options.c, and one for
pager.c). But the 'exec_name' field is used by multiple files, so it
wouldn't necessarily be a clean split. It would also possibly create
more room for error for the users of libapi, since there would then be
three config interfaces instead of one.

So do not try to keep in a single struct unrelated stuff, create two.

Humm, and now that you talk... libapi was supposed to be just sugar
coating kernel APIs, perhaps we need to put it somewhere else in
tools/lib/ than in tools/lib/api/?

Ok. Instead of per-file structs, if there are no objections, I think
I'll go with per-file init functions. For example:
void exec_cmd_init(const char *exec_name, const char *prefix,
const char *exec_path, const char *exec_path_env);
void pager_init(const char *pager_env);
I think that would be a clearer and less surprising interface.

Ah, I didn't realize libapi was a kernel API abstraction library. Shall
we put it in tools/lib/util instead?

Yay, naming discussion! ;-)
So if this is about abstracting out the (Git derived) command-line option parsing
UI and help system, 'util' sounds a bit too generic.
We could call it something like 'lib/cmdline', 'lib/options'?
The (old) argument against making too finegrained user-space libraries was that
shared libraries do have extra runtime costs - this thinking resulted in catch-all
super-libraries like libgtk:
size /usr/lib/x86_64-linux-gnu/libgtk-3.so.0
text data bss dec hex filename
7199789 57712 15128 7272629 6ef8b5 /usr/lib/x86_64-linux-gnu/libgtk-3.so.0
But in tools/ we typically link the libraries statically so there's no shared
library cost to worry about. (Build time linking is a good idea anyway, should we
ever want to make use of link-time optimizations. It also eliminates version skew
and library compatibility breakage.)
The other reason for the emergence of super-libraries was the high setup cost of
new libraries: it's a lot easier to add yet another unrelated API to libgtk than
to start up a whole new project and a new library. But this setup cost is very low
in tools/ - one of the advantage of shared repositories.
So I think in tools/lib/ we can continue to do a clean topical separation of
libraries, super-libraries are not needed.
Thanks,
Ingo

I definitely agree that for the reasons you outlined, something like
'lib/cmdline' would be a good idea. Except... there's a wrinkle, of
course.
The library also includes non-cmdline-related dependencies. And these
dependencies are directly used by perf as well. So if we name it
'cmdline', perf would have includes like:
#include <cmdline/pager.h>
#include <cmdline/strbuf.h>
#include <cmdline/term.h>
#include <cmdline/wrapper.h>
...etc...
So it would be using several functions from the 'cmdline' library which
are unrelated to 'cmdline'.
For that reason I would vote to name it 'lib/util'. But I don't really
care, I'd be ok with 'lib/marshmallow' if that's what you guys wanted
:-)
Thoughts?

Applied, after some minor fixups due to the fact that the previous patch
is still being discussed.

Right, now you see why this wasn't librarised before, huh? Untangling
bits in a way that this gets sane takes a bit of time.
I'm going thru your patchkit to erode it a bit, taking uncontroversial
patches.
I also would just do one thing first, i.e. just move the cmdline parts
to lib/cmdline/, then we would look at the rest. I.e. reduce the problem
first.
Yeah, I haven't looked deeply how difficult that would be :-\

Ok. I've taken a deeper look at how we could just have a 'cmdline'
library without the extra unrelated utils.
(BTW, I actually think a name like 'subcmd' would be a better fit than
'cmdline'. Because it deals not only with the cmdline, but more
specifically with subcommands, as well as the exec'ing of external
subcommands and other subprograms. And any program that wants to have a
"perf"- or "git"-like "subcommand" interface would use it, thus 'subcmd'
is a more natural fit.)
I looked at the files which are unrelated to subcommands and which are
used by both the subcmd code and perf:
- abspath.c: needed by exec_cmd.c for the make_nonrelative_path()
function, but it's a small function which can just be duplicated by
copying it into exec_cmd.c.
- ctype.c: used by parse-options.c for tolower(), but it's not strictly
necessary; instead the glibc version of tolower() can be used.
- pager.c: this isn't directly 'cmdline' related, but does fit the theme
of 'subcmd', since it pipes a child process to 'less'. So it could
reasonably live in the library.
- strbuf.c: used sparingly by parse-options.c, exec_cmd.c, and help.c.
I think all the uses can be replaced rather easily with calls to
sprintf() and similar glibc string functions.
(Another option would be to duplicate the ~150 lines of strbuf.c
inside the library. That would require renaming all the functions and
structs in order to avoid duplicate symbol errors when linking with
perf.)
- term.c: used by help.c for the get_term_dimensions() function, which
is a small function which can be duplicated in help.c.
- usage.c: used in several places for die() and error(), but these are
trivial functions which can be duplicated.
- wrapper.c: used in a few places for ALLOC_GROW() and xrealloc(), but
ALLOC_GROW() can be duplicated locally and xrealloc() can be replaced
by the use of realloc().
So in summary, with a small amount of code duplication, and a little
rewrite of the strbuf usage, I think I can extract a libsubcmd rather
cleanly.
How does that sound?

'subcmd' looks good to me too.

I vaguely recall that it's related to a locale issue. But I don't
know what was the problem exactly.

Not sure it's ok to call die() or similar in a library. The error
should be reported to the caller rather than exiting inside unless
explicitly requested like in usage_with_options() IMHO.

I think it's better to remove this exit_browser() part from util_cfg
(or whatever name it). The usage_with_options() deals with command
line arguments and options so they should be processed before entering
any UI (browser) code.
AFAICS there're only few callers of this function after
setup_browser() and it seems possible to change them to do the works
before setup_browser(). Will try to send patches soon.
Thanks,
Namhyung

perf tools: Save cmdline arguments earlier
perf_env__set_cmdline() only saves the arguments the first time it's
called. It doesn't need to be called every time the options and
suboptions are parsed. Instead it can just be called once.
This also has the advantage of making the option parsing code less
perf-specific so it can be moved out to a library.

go for it, use asprintf, probably is all that is needed, it will
allocate and format, extending would be just using existing stuff plus
new call to asprintf.

Ah, I think you're right. From the ctype man page:
If c is a uppercase letter, tolower() returns its lowercase
equivalent, if a lowercase representation exists in the current
locale.
In this case, tolower() is just used for sorting the printed option list
by the lowercase version of their short option. IMO it's fine to use
the glibc locale-specific conversion here.

Thanks, good point. I'll try to remove all exits from the library
(except for the explicit requests).

Yes, this is much better than both 'libutil' and 'libmarshmallow' ;-)

As it turns out, some special options like '--list-opts' and
'--list-cmds' are implemented within parse_options_subcommand(), which
then does an exit(). If those exit()'s were replaced with negative
return codes, we'd have to provide a way for callers to distinguish
between a normal early exit and a real error (in which the usage
printout might be appropriate). That would be a disruptive change and
require the 40+ callers of the parse_options*() functions to have more
complexity (because they'd need to check for more return conditions).
So I'm thinking I'll leave the code as it is for now and just document
the fact that these functions can exit().

Well, what you're doing is an improvement, so lets go with it. But I'm
not afraid of at some point doing a N+ files change if that makes sense,
and I find any panic() like libary function to be horrible and in need
of removing.

Fair enough, as code using this library will live in tools/ we can
always change all the callers in one go when we see fit.
