1 2009-08-18 Christian Hergert <chris@dronelabs.com>
4 * mono-cov.c: Add missing method declarations.
6 2009-08-14 Massimiliano Mantione <massi@ximian.com>
7 * mono-profiler-logging.c (disable_profiler):
8 Flush buffers synchronously so the GUI knows when we are done.
10 2009-08-14 Massimiliano Mantione <massi@ximian.com>
11 * mono-profiler-logging.c:
12 - Added user thread reading commands from a local tcp port.
13 - Fixed file flushing after writing a block.
14 - Force full buffer flushing after disabling the profiler.
16 2009-08-06 Massimiliano Mantione <massi@ximian.com>
17 * mono-profiler-logging.c:
18 - Avoid registering the writer thread with the runtime unless when
19 it must create a heap snapshot.
20 - Simplified buffer flushing when an appdomain, image or assembly is
21 unloaded (now it can be done in the current thread).
22 - During shutdown, moved "code chunk cleanup" is a region of code
23 that holds the profiler lock.
25 2009-07-29 Massimiliano Mantione <massi@ximian.com>
26 * mono-profiler-logging.c: Implemented data structures to keep track
27 of code buffers produced by the runtime, and used them instead of
28 jit_info_table_find for the statistical profiler.
29 This eliminates crashes related to problems with the writer thread and
30 its registration to the runtime.
32 2009-06-18 Massimiliano Mantione <massi@ximian.com>
33 * mono-profiler-logging.c: Removed debugging printf statement.
35 2009-06-18 Massimiliano Mantione <massi@ximian.com>
36 * mono-profiler-logging.c:
37 Added assembly information to classes and wrapper flag to methods.
39 2009-05-25 Massimiliano Mantione <massi@ximian.com>
40 * mono-profiler-logging.c (write_thread_data_block): Only emit initial
41 stack snippet if we are tracking stacks.
43 2009-05-25 Massimiliano Mantione <massi@ximian.com>
44 * mono-profiler-logging.c (setup_user_options): Avoid tracking stacks
45 and emitting allocation caller information if we are already emitting
46 method enter and exit events.
48 2009-04-06 Massimiliano Mantione <massi@ximian.com>
49 * mono-profiler-logging.c: Added monitor contention profiling.
50 - Changed RESERVE_EVENTS to require a call to the new
51 COMMIT_RESERVED_EVENTS macro after we have filled the event slots
52 (this allows to acquire all the event slots atomically).
53 - Created utility function "save_stack_delta".
54 - Created "monitor_event" callback.
55 - renamed "handle_heap_profiling" as "process_gc_event" because it
56 must be used also to help avoid interferences between garbage
57 collections and monitor profiling.
59 2009-03-23 Massimiliano Mantione <massi@ximian.com>
60 * mono-profiler-logging.c: Removed useless "gc-signal" option (the
61 newer "heap=<SIGNAL>" format of the "heap" option does the same thing).
63 2009-03-16 Massimiliano Mantione <massi@ximian.com>
64 * mono-profiler-logging.c: When checking if an elf file is valid,
65 avoid mapping it in memory until we know it's usable (avoids virtual
66 memory fragmentation issues).
68 2009-01-25 Massimiliano Mantione <massi@ximian.com>
69 * mono-profiler-logging.c: Bug fixing.
70 The issue is that while reading /proc/self/maps is can happen that
71 the last regions (typically [vsyscall] and [vsdo]) are reported more
72 than once (or anyway are read more than once, even when usng the plain
73 "read" call with no buffering), and I found no workaround for this.
74 So the code must be careful and throw away the duplicates.
75 - restore_old_regions: work starting from the new regions instead of
77 - sort_regions: introduce a "throw away the duplicates" pass.
78 - fix_region_references: added a pass to make sure that the elf files
79 always reference the new regions and not the old ones.
80 - refresh_memory_regions: call "sort_regions" before
81 "restore_old_regions" so we know we have no duplicates.
83 2009-01-18 Massimiliano Mantione <massi@ximian.com>
84 * mono-profiler-logging.c: Bug fixing.
85 - profiler_executable_memory_region_destroy: fixed a cut&paste mistake
86 causing a double free.
87 - executable_file_open: allow the code to look at all files, and fix
88 building of "files->new_files" list.
89 - executable_file_free: set "file->section_regions" to NULL when
90 freeing it (for safety).
92 2008-12-31 Massimiliano Mantione <massi@ximian.com>
93 * mono-profiler-logging.c: added "save-allocation-caller" option.
95 2008-12-30 Massimiliano Mantione <massi@ximian.com>
96 * mono-profiler-logging.c:
97 - profiler_executable_memory_region_destroy: fixed memory region
99 - executable_file_add_region_reference: likewise.
100 - executable_file_close: likewise.
101 - executable_file_open: fixed file name handling.
102 - parse_map_line: likewise.
103 - scan_process_regions: likewise.
104 - statistical_call_chain: exit loop if the writer thread is busy.
106 2008-12-11 Massimiliano Mantione <massi@ximian.com>
107 * mono-profiler-logging.c:
108 - executable_file_open: Proper remember of already opened files.
109 - ProfilerStatisticalData: use unsigned values so the index never
110 trips over and becomes negative.
111 - statistical_call_chain, statistical_hit: likewise.
113 2008-12-11 Massimiliano Mantione <massi@ximian.com>
114 * mono-profiler-logging.c: Added defaults to command line options.
116 2008-12-01 Massimiliano Mantione <massi@ximian.com>
117 * mono-profiler-logging.c:
118 - ProfilerThreadStack: added "last_written_frame" and "written_frames"
119 fields to keep track of the call stacks actually written, so that we
120 can "replay" the full call stack at the beginning of each event block
121 (which allows the decoder to read blocks in random order and still see
122 all the call stacks correctly).
123 - gc_event: Fixed event creation sequence.
124 - Improved event logging (debugging) code.
126 2008-11-04 Massimiliano Mantione <massi@ximian.com>
127 * mono-profiler-logging.c:
128 Make sure that stack sections can be fully reconstructed even reading
131 2008-10-10 Massimiliano Mantione <massi@ximian.com>
132 * mono-profiler-logging.c:
133 Added "aci" option to emit the object "id" at each allocation.
135 2008-10-10 Massimiliano Mantione <massi@ximian.com>
136 * mono-profiler-logging.c:
137 Added support for handling the stack trace of each allocation event.
138 - MonoProfilerDirectives: added directive to state that allocations
139 have stack traces (not strictly needed, but simplifirs the decoder).
140 - ProfilerEventData: gave one more bit to code (and one less to value).
141 - MonoProfilerEvents: Added "stack section" event to record stack state.
142 - ProfilerThreadStack: added last_saved_top to track what we just saved.
143 - _MonoProfiler::action_flags: Added save_allocation_caller and
144 save_allocation_stack to state what we do for allocations.
145 - All "thread_stack_..." functions: Track last_saved_top.
146 - Added thread_stack_count_unsaved_frames utilty function.
147 - write_directives_block: handle ALLOCATIONS_HAVE_STACK directive.
148 - Added write_stack_section_event function.
149 - write_event: also handle emission of stack sections.
150 - Reworked all the "STORE_EVENT_..." macros to work on arbitrary event
151 slots (needed for stack sections), and as a consequence fixed all the
152 functions that use them.
153 - object_allocated: save "delta" stack section if needed.
154 - setup_user_options: handle new "sas" option.
156 2008-09-08 Massimiliano Mantione <massi@ximian.com>
157 * Makefile.am: Don't build the profilers if DISABLE_PROFILER is set.
159 2008-09-08 Massimiliano Mantione <massi@ximian.com>
160 * mono-profiler-logging.c:
161 - setup_user_options: made so that the user has to explicitly request
162 the "f" mode when the "h" is asked, otherwise the number of snapshot
163 blocks in the file is very confusing.
164 - Added three icalls to control the profiler from the profiled
167 2008-08-28 Zoltan Varga <vargaz@gmail.com>
169 * mono-profiler-logging.c (detect_fast_timer): Add missing return type.
171 2008-08-21 Massimiliano Mantione <massi@ximian.com>
172 * mono-profiler-logging.c: Added support for correct accounting of
173 allocations which happened at JIT time.
175 2008-08-20 Massimiliano Mantione <massi@ximian.com>
176 * mono-profiler-logging.c: Added directives block, and used it to
177 state that "allocation attribution" done using the stack tracking (so
178 that allocation callers are directly written in the log file).
180 2008-07-28 Massimiliano Mantione <massi@ximian.com>
181 * mono-profiler-logging.c: Added stack tracking (even if still unused).
183 2008-07-28 Massimiliano Mantione <massi@ximian.com>
184 * mono-profiler-logging.c: Fix bug 412473:
185 - write_statistical_data_block: check if the current MonoThread still
186 exists, and if not avoid calling mono_jit_info_table_find.
187 - profiler_shutdown: flush everything in the current thread.
189 2008-07-28 Massimiliano Mantione <massi@ximian.com>
190 * mono-profiler-logging.c: Fix the "allocation summaries" feature
191 (I committed it but it never really worked until now).
193 2008-07-04 Massimiliano Mantione <massi@ximian.com>
194 * mono-profiler-logging.c: Emit full type names for loaded classes
195 (patch by Rodrigo Kumpera).
197 2008-07-04 Massimiliano Mantione <massi@ximian.com>
198 * mono-profiler-logging.c: Use the new "runtime initialized" hook.
200 2008-07-04 Massimiliano Mantione <massi@ximian.com>
201 * mono-profiler-logging.c: Fix an embarassingly stupid problem with
204 2008-07-03 Massimiliano Mantione <massi@ximian.com>
205 * mono-profiler-logging.c: Changed the way to wait for the writer
206 thread to avoid passing an invalid handle to pthread_join.
208 2008-06-28 Massimiliano Mantione <massi@ximian.com>
209 * mono-profiler-logging.c: When offloading flushing to the writer
210 thread, first check that it still exists.
212 2008-06-25 Massimiliano Mantione <massi@ximian.com>
213 * mono-profiler-logging.c: Offload more flushing to the writer thread,
214 and fix the shutdown sequence.
216 2008-06-25 Massimiliano Mantione <massi@ximian.com>
217 * mono-profiler-logging.c: Made so that at appdomain unload the
218 buffers are flushed by the profiler worker thread (which we know
219 is registered with the runtime).
221 2008-06-25 Massimiliano Mantione <massi@ximian.com>
222 * mono-profiler-logging.c: Added more logging code.
224 2008-06-25 Massimiliano Mantione <massi@ximian.com>
225 * mono-profiler-logging.c: Record also the domain of each statistical
226 hit, so that mono_jit_info_table_find works properly.
228 2008-06-25 Massimiliano Mantione <massi@ximian.com>
229 * mono-profiler-logging.c: Fixed breakage introduced in r105966
231 2008-06-17 Massimiliano Mantione <massi@ximian.com>
232 * mono-profiler-logging.c: Implemented signal based enable-disable
233 toggling for the statistical and enter-exit events.
235 2008-06-17 Massimiliano Mantione <massi@ximian.com>
236 * mono-profiler-logging.c (write_statistical_hit): Use the proper
237 domain instead of trying to get one.
239 2008-06-16 Massimiliano Mantione <massi@ximian.com>
240 * mono-profiler-logging.c (module_end_load, assembly_end_load):
241 Properly check the return value of "mono_assembly_fill_assembly_name",
242 otherwise "mono_stringify_assembly_name" can crash.
244 2008-06-16 Massimiliano Mantione <massi@ximian.com>
245 * mono-profiler-logging.c: Fix a segfault on shutdown (see Marek's
246 fix for the default profiler in r105466, the problem is the same.
248 2008-06-16 Massimiliano Mantione <massi@ximian.com>
249 * mono-profiler-logging.c: Initial implementation of summary report
250 for allocations at each collection.
252 2008-05-23 Massimiliano Mantione <massi@ximian.com>
253 * mono-profiler-logging.c: Fix warnings x86 and remove debugging code.
255 2008-05-23 Massimiliano Mantione <massi@ximian.com>
256 * mono-profiler-logging.c: Fix the build on x86.
258 2008-05-23 Massimiliano Mantione <massi@ximian.com>
259 * mono-profiler-logging.c: Support call chains (backtrace) in the
262 2008-05-12 Massimiliano Mantione <massi@ximian.com>
263 * mono-profiler-logging.c (handle_heap_profiling): Flush all data
264 buffers, so that objext allocation events are written before the heap
265 description (which contains the "object free" events).
267 2008-05-12 Massimiliano Mantione <massi@ximian.com>
268 * mono-profiler-logging.c: Added support for a global counter of all
269 garbage collections, so that the file decoder can correlate the
272 2008-05-12 Massimiliano Mantione <massi@ximian.com>
273 * mono-profiler-logging.c: Fixed a bug that prevented using rdtsc,
274 and enabled rdtsc by default,adding a command line option to revert
275 to using gettimeofday.
277 2008-05-02 Massimiliano Mantione <massi@ximian.com>
278 * mono-profiler-logging.c: Turned DEBUG_STATISTICAL_PROFILER off...
280 2008-05-02 Massimiliano Mantione <massi@ximian.com>
281 * mono-profiler-logging.c : Rework statistical profiler, adding the
282 ability to scan symbol tables in elf files instead of using dladdr
283 (dladdr skips lots of symbols which this way we get correctly).
285 2008-04-16 Massimiliano Mantione <massi@ximian.com>
286 * mono-profiler-logging.c (gc_event): Fix deadlock condition.
288 2008-04-16 Massimiliano Mantione <massi@ximian.com>
289 * mono-profiler-logging.c (write_current_block): Added an incremental
290 "counter delta" field to the block header, so that each block has a
291 timestamp directly in the header.
292 This will allow tools to know when a block has been emitted without
293 decoding (even without reading) the block contents.
294 So, if the user is only interested in blocks emitted in a certain
295 time interval, the tool can seek into the file instead of reading the
297 Of course this breaks the file format, but at this stage we can still
298 do it, and... better now than later.
300 2008-04-10 Massimiliano Mantione <massi@ximian.com>
301 * mono-profiler-logging.c (profiler_heap_scan): removed debugging code
302 and therefore removed unconditional inclusion of signal.h (it is now
303 included anyway on Unix platforms).
305 2008-04-10 Massimiliano Mantione <massi@ximian.com>
306 * mono-profiler-logging.c: Added possibiliy of requesting heap
307 snapshots with a signal (like heap-shot).
309 2008-04-02 Rodrigo Kumpera <rkumpera@novell.com>
311 * mono-profiler-logging.c: Fix the arm build. G_BREAKPOINT() does
312 a "raise(SIGTRAL)" and in some platforms <signal.h> must be included.
314 2008-03-28 Massimiliano Mantione <massi@ximian.com>
315 * mono-profiler-logging.c: Added option to append a suffix to the
318 2008-03-27 Massimiliano Mantione <massi@ximian.com>
319 * mono-profiler-logging.c: setup_user_options: set default log file
320 name to the name of the executed application.
322 2008-03-26 Massimiliano Mantione <massi@ximian.com>
323 * Makefile.am: enabled the logging profiler on Linux.
325 2008-03-26 Massimiliano Mantione <massi@ximian.com>
326 * mono-profiler-logging.c: Attach and detach the writer thread.
328 2008-03-25 Massimiliano Mantione <massi@ximian.com>
329 * mono-profiler-logging.c: Fixed bug with memory region indexes.
331 2008-03-18 Massimiliano Mantione <massi@ximian.com>
332 * mono-profiler-logging.c:
333 OPEN_FILE(): Fixed file creation.
334 [UN]LOCK_PROFILER(): Removed logging message.
336 2008-03-11 Massimiliano Mantione <massi@ximian.com>
337 * mono-profiler-logging.c: Fixed heap profiler, added a new way to
338 get the symbol names for unmanaged functions, and fixed lots of bugs.
340 2008-01-08 Massimiliano Mantione <massi@ximian.com>
341 * mono-profiler-logging.c: First code drop of new logging profiler
342 (and shamefully forgot to set HAS_OPROFILE to 0...).
343 * Makefile.am: Added logging profiler, but commented in out to avoid
344 breaking the build on Windows.
346 2005-07-25 Zoltan Varga <vargaz@freemail.hu>
348 * mono-cov.c: Applied patch from Iain McCoy (iain@mccoy.id.au). Fixes
351 2003-11-12 Jackson Harper <jackson@ximian.com>
353 * mono-cov.c: Change default assembly name to mscorlib.dll
355 Tue Jul 1 11:26:10 CEST 2003 Paolo Molaro <lupus@ximian.com>
357 * Makefile.am: added.
359 Mon Jun 16 18:21:26 CEST 2003 Paolo Molaro <lupus@ximian.com>
361 * mono-cov.c: coverage profiler.
