statprof: separate functions and "line", assume 4 digit line numbers Previously, the profile output looked like this (I've removed many lines that are mostly inconsequential): ``` | 100.0% 0.02s hg: <module> line 43: dispatch.run() | 100.0% 0.02s dispatch.py: run line 115: status = dispatch(req) | 100.0% 0.02s dispatch.py: _runcatchfunc line 432: return _dispatch(req) \ 50.0% 0.01s dispatch.py: _dispatch line 1228: return runcommand( | 50.0% 0.01s dispatch.py: runcommand line 883: ret = _runcommand(ui, optio... | 50.0% 0.01s dispatch.py: _runcommand line 1240: return cmdfunc() | 50.0% 0.01s localrepo.py: __getitem__ line 1670: quick_access = self._quick_... | 50.0% 0.01s localrepo.py: _quick_access_changeidline 1650: return self._quick_access_c... | 50.0% 0.01s localrepo.py: __get__ line 179: return getattr(unfi, self.n... | 50.0% 0.01s util.py: __get__ line 1747: result = self.func(obj) | 50.0% 0.01s localrepo.py: _quick_access_changeid_wcline 1611: cl = self.unfiltered().chan... | 50.0% 0.01s localrepo.py: __get__ line 110: return super(_basefilecache... | 50.0% 0.01s util.py: __getattribute__line 245: self.__spec__.loader.exec_m... | 50.0% 0.01s <frozen importlib._bootstrap_external>: exec_moduleline 783: | 50.0% 0.01s <frozen importlib._bootstrap>: _call_with_frames_removedline 219: | 50.0% 0.01s changelog.py: <module> line 376: class changelog(revlog.revl... | 50.0% 0.01s util.py: __getattribute__line 245: self.__spec__.loader.exec_m... | 50.0% 0.01s <frozen importlib._bootstrap_external>: exec_moduleline 779: | 50.0% 0.01s <frozen importlib._bootstrap_external>: get_codeline 868: | 50.0% 0.01s <frozen importlib._bootstrap_external>: path_statsline 1012: | 50.0% 0.01s <frozen importlib._bootstrap_external>: _path_statline 87: ``` This has a few problems, though I'm only addressing some of them. 1. If the stuff before "line ###" is long, there's no separation between the function name and the "line" string. 2. If the stuff before "line ###" is really long, there's excessive separation between the "line" string and the line number. 3. We frequently have 4-digit line numbers, the code on the right wasn't dynamically indented and ended up quite messy looking. To solve these problems, I've added a ", " prefix before "line" iff it would otherwise not have any separation such as spaces. I've added a 'max' so that we never use a negative width (which is the cause of problem #2 above), and I've added a default assumption of 4 digit line numbers (but again using a 'max' so this shouldn't cause problems if we go beyond that. With these changes, it now looks like this: ``` | 100.0% 0.02s hg: <module> line 43: dispatch.run() | 100.0% 0.02s dispatch.py: run line 115: status = dispatch(req) | 100.0% 0.02s dispatch.py: _runcatchfunc line 432: return _dispatch(req) \ 50.0% 0.01s dispatch.py: _dispatch line 1228: return runcommand( | 50.0% 0.01s dispatch.py: runcommand line 883: ret = _runcommand(ui, optio... | 50.0% 0.01s dispatch.py: _runcommand line 1240: return cmdfunc() | 50.0% 0.01s localrepo.py: __getitem__ line 1670: quick_access = self._quick_... | 50.0% 0.01s localrepo.py: _quick_access_changeid, line 1650: return self._quick_access_c... | 50.0% 0.01s localrepo.py: __get__ line 179: return getattr(unfi, self.n... | 50.0% 0.01s util.py: __get__ line 1747: result = self.func(obj) | 50.0% 0.01s localrepo.py: _quick_access_changeid_wc, line 1611: cl = self.unfiltered().chan... | 50.0% 0.01s localrepo.py: __get__ line 110: return super(_basefilecache... | 50.0% 0.01s util.py: __getattribute__, line 245: self.__spec__.loader.exec_m... | 50.0% 0.01s <frozen importlib._bootstrap_external>: exec_module, line 783: | 50.0% 0.01s <frozen importlib._bootstrap>: _call_with_frames_removed, line 219: | 50.0% 0.01s changelog.py: <module> line 376: class changelog(revlog.revl... | 50.0% 0.01s util.py: __getattribute__, line 245: self.__spec__.loader.exec_m... | 50.0% 0.01s <frozen importlib._bootstrap_external>: exec_module, line 779: | 50.0% 0.01s <frozen importlib._bootstrap_external>: get_code, line 868: | 50.0% 0.01s <frozen importlib._bootstrap_external>: path_stats, line 1012: | 50.0% 0.01s <frozen importlib._bootstrap_external>: _path_stat, line 87: ``` Differential Revision: https://phab.mercurial-scm.org/D9511
