[RFC][PATCH v2 00/24] tools lib traceevent: Rename pevent to tep for preparation for library

  Resending as quilt mail threading was broken, but luckily was fixed by
 http://git.savannah.nongnu.org/cgit/quilt.git/commit/?id=360b85e1f6b6d1aff5ada942fcee816e1ad7a13c
  And has been reported to Debian:
   https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=900784
]
  
Having libtraceevent turn into a proper library has long been asked for.
I never had time to do it before. Luckily, Tzvetomir was able to spend
the time to start the preparation. The first thing that needs to be done
is to handle namespace collisions. "pevent" was the prefix I chose, but
many people were displeased by it, as it didn't express what the functions
were used for. After discussing with many people at many conferences
I've come up with "tep", which means "Trace Event Parser". Please don't
question this. The bikeshed has been painted and I'm not changing the
color.

This series changes all the function names and data structures from the
"pevent_" prefix to the "tep_" prefix. Note, it does not change the
names of local variables or even parameters. "pevent" variables and
parameters still exist. We can change those later, but for now, I want
all global references to "pevent" to be "tep_" instead.

This is not complete. It is only one of many preparations to make
libtraceevent into a legitimate library. There's other naming conventions
that will be made. But for now, I would like to hear thoughts about
this change before we proceed further.

Instead of doing one big update, Tzvetomir grouped changes together.
I compiled each patch to make sure perf still builds without errors
at each step. I only used my own configuration, thus there may be
cases that perf might fail to build. Here's what I had:

Auto-detecting system features:
...                         dwarf: [ on  ]
...            dwarf_getlocations: [ on  ]

...                      libaudit: [ OFF ]
...                        libbfd: [ on  ]
...                        libelf: [ on  ]
...                       libnuma: [ OFF ]
...        numa_num_possible_cpus: [ OFF ]
...                       libperl: [ OFF ]
...                     libpython: [ on  ]
...                      libslang: [ OFF ]
...                     libcrypto: [ on  ]
...                     libunwind: [ OFF ]
...            libdw-dwarf-unwind: [ on  ]
...                          zlib: [ on  ]
...                          lzma: [ on  ]
...                     get_cpuid: [ on  ]
...                           bpf: [ on  ]

The above is the config I used for testing the build.

[RFC][PATCH v2 01/24] tools/lib/traceevent, tools/perf: Rename struct pevent to struct tep_handle

[Steven Rostedt]

From: "Tzvetomir Stoyanov (VMware)" <tz.stoyanov@gmail.com>

In order to make libtraceevent into a proper library, variables, data
structures and functions require a unique prefix to prevent name space
conflicts. That prefix will be "tep_" and not "pevent_". This changes
the struct pevent to struct tep_handle.

tools lib traceevent, perf tools: Rename struct pevent to struct tep_handle

In order to make libtraceevent into a proper library, variables, data
structures and functions require a unique prefix to prevent name space
conflicts. That prefix will be "tep_" and not "pevent_". This changes
the struct pevent to struct tep_handle.

[RFC][PATCH v2 02/24] tools/lib/traceevent, tools/perf: Rename struct pevent_record to struct tep_record

[Steven Rostedt]

From: "Tzvetomir Stoyanov (VMware)" <tz.stoyanov@gmail.com>

In order to make libtraceevent into a proper library, variables, data
structures and functions require a unique prefix to prevent name space
conflicts. That prefix will be "tep_" and not "pevent_". This changes
the struct pevent_record to struct tep_record.

tools lib traceevent, perf tools: Rename 'struct pevent_record' to 'struct tep_record'

In order to make libtraceevent into a proper library, variables, data
structures and functions require a unique prefix to prevent name space
conflicts. That prefix will be "tep_" and not "pevent_". This changes
the 'struct pevent_record' to 'struct tep_record'.

[RFC][PATCH v2 03/24] tools/lib/traceevent, tools/perf: Rename pevent plugin related APIs

[Steven Rostedt]

From: "Tzvetomir Stoyanov (VMware)" <tz.stoyanov@gmail.com>

In order to make libtraceevent into a proper library, variables, data
structures and functions require a unique prefix to prevent name space
conflicts. That prefix will be "tep_" and not "pevent_". This changes
the pevent plugin related API.

tools lib traceevent, perf tools: Rename pevent plugin related APIs

In order to make libtraceevent into a proper library, variables, data
structures and functions require a unique prefix to prevent name space
conflicts. That prefix will be "tep_" and not "pevent_". This changes
the pevent plugin related API.

[RFC][PATCH v2 04/24] tools/lib/traceevent, tools/perf: Rename pevent alloc / free APIs

[Steven Rostedt]

From: "Tzvetomir Stoyanov (VMware)" <tz.stoyanov@gmail.com>

In order to make libtraceevent into a proper library, variables, data
structures and functions require a unique prefix to prevent name space
conflicts. That prefix will be "tep_" and not "pevent_". This changes
APIs: pevent_alloc, pevent_free, pevent_event_info and pevent_func_resolver_t

[RFC][PATCH v2 05/24] tools/lib/traceevent, tools/perf: Rename pevent find APIs

[Steven Rostedt]

From: "Tzvetomir Stoyanov (VMware)" <tz.stoyanov@gmail.com>

In order to make libtraceevent into a proper library, variables, data
structures and functions require a unique prefix to prevent name space
conflicts. That prefix will be "tep_" and not "pevent_". This changes
APIs: pevent_find_any_field, pevent_find_common_field, pevent_find_event,
pevent_find_field

tools lib traceevent, perf tools: Rename pevent find APIs

In order to make libtraceevent into a proper library, variables, data
structures and functions require a unique prefix to prevent name space
conflicts. That prefix will be "tep_" and not "pevent_". This changes
APIs: pevent_find_any_field, pevent_find_common_field,
pevent_find_event, pevent_find_field

[RFC][PATCH v2 06/24] tools/lib/traceevent, tools/perf: Rename pevent parse APIs

[Steven Rostedt]

From: "Tzvetomir Stoyanov (VMware)" <tz.stoyanov@gmail.com>

In order to make libtraceevent into a proper library, variables, data
structures and functions require a unique prefix to prevent name space
conflicts. That prefix will be "tep_" and not "pevent_". This changes
APIs: pevent_parse_event, pevent_parse_format, pevent_parse_header_page

Signed-off-by: Tzvetomir Stoyanov (VMware) <tz.stoyanov@gmail.com>

tools lib traceevent, perf tools: Rename pevent parse APIs

In order to make libtraceevent into a proper library, variables, data
structures and functions require a unique prefix to prevent name space
conflicts. That prefix will be "tep_" and not "pevent_". This changes
APIs: pevent_parse_event, pevent_parse_format, pevent_parse_header_page

[RFC][PATCH v2 07/24] tools/lib/traceevent, tools/perf: Rename pevent print APIs

[Steven Rostedt]

From: "Tzvetomir Stoyanov (VMware)" <tz.stoyanov@gmail.com>

In order to make libtraceevent into a proper library, variables, data
structures and functions require a unique prefix to prevent name space
conflicts. That prefix will be "tep_" and not "pevent_". This changes
APIs: pevent_print_field, pevent_print_fields, pevent_print_funcs,
pevent_print_printk

tools lib traceevent, perf tools: Rename pevent print APIs

In order to make libtraceevent into a proper library, variables, data
structures and functions require a unique prefix to prevent name space
conflicts. That prefix will be "tep_" and not "pevent_". This changes
APIs: pevent_print_field, pevent_print_fields, pevent_print_funcs,
pevent_print_printk

[RFC][PATCH v2 08/24] tools/lib/traceevent, tools/perf: Rename pevent_read_number_* APIs

[Steven Rostedt]

From: "Tzvetomir Stoyanov (VMware)" <tz.stoyanov@gmail.com>

In order to make libtraceevent into a proper library, variables, data
structures and functions require a unique prefix to prevent name space
conflicts. That prefix will be "tep_" and not "pevent_". This changes
APIs: pevent_read_number, pevent_read_number_field

tools lib traceevent, perf tools: Rename pevent_read_number_* APIs

In order to make libtraceevent into a proper library, variables, data
structures and functions require a unique prefix to prevent name space
conflicts. That prefix will be "tep_" and not "pevent_". This changes
APIs: pevent_read_number, pevent_read_number_field

tools lib traceevent, perf tools: Rename pevent_set_* APIs

In order to make libtraceevent into a proper library, variables, data
structures and functions require a unique prefix to prevent name space
conflicts. That prefix will be "tep_" and not "pevent_". This changes
APIs: pevent_set_file_bigendian, pevent_set_flag,
pevent_set_function_resolver, pevent_set_host_bigendian,
pevent_set_long_size, pevent_set_page_size and pevent_get_long_size

[RFC][PATCH v2 11/24] tools/lib/traceevent, tools/perf: Rename traceevent_* APIs

[Steven Rostedt]

From: "Tzvetomir Stoyanov (VMware)" <tz.stoyanov@gmail.com>

In order to make libtraceevent into a proper library, variables, data
structures and functions require a unique prefix to prevent name space
conflicts. That prefix will be "tep_" and not "traceevent_". This changes
APIs: traceevent_host_bigendian, traceevent_load_plugins and traceevent_unload_plugins

tools lib traceevent, tools lib lockdep: Rename 'enum pevent_errno' to 'enum tep_errno'

In order to make libtraceevent into a proper library, variables, data
structures and functions require a unique prefix to prevent name space
conflicts. That prefix will be "tep_" and not "pevent_". This changes
'enum pevent_errno' to 'enum tep_errno'.

[RFC][PATCH v2 14/24] tools/lib/traceevent: Rename pevent_function* APIs

[Steven Rostedt]

From: "Tzvetomir Stoyanov (VMware)" <tz.stoyanov@gmail.com>

In order to make libtraceevent into a proper library, variables, data
structures and functions require a unique prefix to prevent name space
conflicts. That prefix will be "tep_" and not "pevent_". This changes
APIs: pevent_function_handler, pevent_func_handler, pevent_func_arg_type,
PEVENT_FUNC_ARG_VOID, PEVENT_FUNC_ARG_INT, PEVENT_FUNC_ARG_LONG,
PEVENT_FUNC_ARG_STRING, PEVENT_FUNC_ARG_PTRS, PEVENT_FUNC_ARG_MAX_TYPES

[RFC][PATCH v2 15/24] tools/lib/traceevent, tools/perf: Rename traceevent_plugin_* APIs

[Steven Rostedt]

From: "Tzvetomir Stoyanov (VMware)" <tz.stoyanov@gmail.com>

In order to make libtraceevent into a proper library, variables, data
structures and functions require a unique prefix to prevent name space
conflicts. That prefix will be "tep_" and not "traceevent_". This changes
APIs: traceevent_plugin_list_options, traceevent_plugin_free_options_list,
traceevent_plugin_add_options, traceevent_plugin_remove_options,
traceevent_print_plugins

[RFC][PATCH v2 16/24] tools/lib/traceevent: Rename pevent_filter* APIs

[Steven Rostedt]

From: "Tzvetomir Stoyanov (VMware)" <tz.stoyanov@gmail.com>

In order to make libtraceevent into a proper library, variables, data
structures and functions require a unique prefix to prevent name space
conflicts. That prefix will be "tep_" and not "pevent_". This changes
APIs: PEVENT_FILTER_ERROR_BUFSZ, pevent_filter_alloc,
pevent_filter_add_filter_str, pevent_filter_match, pevent_filter_strerror,
pevent_event_filtered, pevent_filter_reset, pevent_filter_clear_trivial,
pevent_filter_free, pevent_filter_make_string, pevent_filter_remove_event,
pevent_filter_event_has_trivial, pevent_filter_copy, pevent_update_trivial,
pevent_filter_compare

[RFC][PATCH v2 17/24] tools/lib/traceevent: Rename pevent_register / unregister APIs

[Steven Rostedt]

From: "Tzvetomir Stoyanov (VMware)" <tz.stoyanov@gmail.com>

In order to make libtraceevent into a proper library, variables, data
structures and functions require a unique prefix to prevent name space
conflicts. That prefix will be "tep_" and not "pevent_". This changes
APIs: pevent_register_print_function, pevent_unregister_print_function,
pevent_register_event_handler, pevent_unregister_event_handler,
pevent_register_function, pevent_register_trace_clock

tools lib traceevent: Rename pevent_register / unregister APIs

In order to make libtraceevent into a proper library, variables, data
structures and functions require a unique prefix to prevent name space
conflicts. That prefix will be "tep_" and not "pevent_". This changes
APIs: pevent_register_print_function, pevent_unregister_print_function,
pevent_register_event_handler, pevent_unregister_event_handler,
pevent_register_function, pevent_register_trace_clock

[RFC][PATCH v2 18/24] tools/lib/traceevent: Rename pevent_data_ APIs

[Steven Rostedt]

From: "Tzvetomir Stoyanov (VMware)" <tz.stoyanov@gmail.com>

In order to make libtraceevent into a proper library, variables, data
structures and functions require a unique prefix to prevent name space
conflicts. That prefix will be "tep_" and not "pevent_". This changes
APIs: pevent_data_lat_fmt, pevent_data_type, pevent_data_event_from_type,
pevent_data_pid, pevent_data_preempt_count, pevent_data_flags,
pevent_data_comm_from_pid, pevent_data_pid_from_comm, pevent_cmdline_pid

tools lib traceevent: Rename pevent_data_ APIs

In order to make libtraceevent into a proper library, variables, data
structures and functions require a unique prefix to prevent name space
conflicts. That prefix will be "tep_" and not "pevent_". This changes
APIs: pevent_data_lat_fmt, pevent_data_type, pevent_data_event_from_type,
pevent_data_pid, pevent_data_preempt_count, pevent_data_flags,
pevent_data_comm_from_pid, pevent_data_pid_from_comm, pevent_cmdline_pid

[RFC][PATCH v2 19/24] tools/lib/traceevent: Rename pevent field APIs

[Steven Rostedt]

From: "Tzvetomir Stoyanov (VMware)" <tz.stoyanov@gmail.com>

In order to make libtraceevent into a proper library, variables, data
structures and functions require a unique prefix to prevent name space
conflicts. That prefix will be "tep_" and not "pevent_". This changes
APIs: pevent_free_format, pevent_free_format_field, pevent_get_field_raw,
pevent_get_field_val, pevent_get_common_field_val, pevent_get_any_field_val

tools lib traceevent: Rename pevent field APIs

In order to make libtraceevent into a proper library, variables, data
structures and functions require a unique prefix to prevent name space
conflicts. That prefix will be "tep_" and not "pevent_". This changes
APIs: pevent_free_format, pevent_free_format_field, pevent_get_field_raw,
pevent_get_field_val, pevent_get_common_field_val, pevent_get_any_field_val

[RFC][PATCH v2 20/24] tools/lib/traceevent: Rename pevent_find_* APIs

[Steven Rostedt]

From: "Tzvetomir Stoyanov (VMware)" <tz.stoyanov@gmail.com>

In order to make libtraceevent into a proper library, variables, data
structures and functions require a unique prefix to prevent name space
conflicts. That prefix will be "tep_" and not "pevent_". This changes
APIs: pevent_find_function, pevent_find_function_address,
pevent_find_event_by_name, pevent_find_event_by_record

Hi Arnaldo,

I'm curious to why the "(VMware)" part of my Signed-off-by was stripped
off on all these patches? It's required that is added to denote that my
work is done on my company time, otherwise I will have to use my vmware
email address which I really don't want to do.

tools lib traceevent: Rename internal parser related APIs

In order to make libtraceevent into a proper library, variables, data
structures and functions require a unique prefix to prevent name space
conflicts. That prefix will be "tep_" and not "pevent_". This changes
APIs: pevent_buffer_init, pevent_read_token, pevent_free_token,
pevent_peek_char, pevent_get_input_buf, pevent_get_input_buf_ptr

[RFC][PATCH v2 23/24] tools/lib/traceevent: Rename various pevent APIs

[Steven Rostedt]

From: "Tzvetomir Stoyanov (VMware)" <tz.stoyanov@gmail.com>

In order to make libtraceevent into a proper library, variables, data
structures and functions require a unique prefix to prevent name space
conflicts. That prefix will be "tep_" and not "pevent_". This changes
APIs: pevent_reset_function_resolver, pevent_strerror, pevent_list_events,
pevent_event_common_fields, pevent_event_fields, pevent_ref, pevent_unref

[RFC][PATCH v2 24/24] tools/lib/traceevent: Rename static variables and functions in event-parse.c

[Steven Rostedt]

From: "Tzvetomir Stoyanov (VMware)" <tz.stoyanov@gmail.com>

In order to make libtraceevent into a proper library, variables, data
structures and functions require a unique prefix to prevent name space
conflicts. That prefix will be "tep_" and not "pevent_". This changes
static variables and functions in event-parse.c: pevent_func_params,
__pevent_parse_format, __pevent_parse_event, pevent_error_str, pevent_search_event
