Appendix A GDB Currently available observers
37
********************************************
39
A.1 Implementation rationale
40
============================
42
An "observer" is an entity which is interested in being notified when
43
GDB reaches certain states, or certain events occur in GDB. The entity
44
being observed is called the "subject". To receive notifications, the
45
observer attaches a callback to the subject. One subject can have
48
`observer.c' implements an internal generic low-level event
49
notification mechanism. This generic event notification mechanism is
50
then re-used to implement the exported high-level notification
51
management routines for all possible notifications.
53
The current implementation of the generic observer provides support
54
for contextual data. This contextual data is given to the subject when
55
attaching the callback. In return, the subject will provide this
56
contextual data back to the observer as a parameter of the callback.
58
Note that the current support for the contextual data is only
59
partial, as it lacks a mechanism that would deallocate this data when
60
the callback is detached. This is not a problem so far, as this
61
contextual data is only used internally to hold a function pointer.
62
Later on, if a certain observer needs to provide support for user-level
63
contextual data, then the generic notification mechanism will need to be
64
enhanced to allow the observer to provide a routine to deallocate the
65
data when attaching the callback.
67
The observer implementation is also currently not reentrant. In
68
particular, it is therefore not possible to call the attach or detach
69
routines during a notification.
74
Observer notifications can be traced using the command `set debug
75
observer 1' (*note Optional messages about internal happenings:
76
(gdb)Debugging Output.).
78
A.3 `normal_stop' Notifications
79
===============================
81
GDB notifies all `normal_stop' observers when the inferior execution
82
has just stopped, the associated messages and annotations have been
83
printed, and the control is about to be returned to the user.
85
Note that the `normal_stop' notification is not emitted when the
86
execution stops due to a breakpoint, and this breakpoint has a
87
condition that is not met. If the breakpoint has any associated
88
commands list, the commands are executed after the notification is
91
The following interfaces are available to manage observers:
93
-- Function: extern struct observer *observer_attach_EVENT
94
(observer_EVENT_ftype *F)
95
Using the function F, create an observer that is notified when
96
ever EVENT occurs, return the observer.
98
-- Function: extern void observer_detach_EVENT (struct observer
100
Remove OBSERVER from the list of observers to be notified when
103
-- Function: extern void observer_notify_EVENT (void);
104
Send a notification to all EVENT observers.
106
The following observable events are defined:
108
-- Function: void normal_stop (struct bpstats *BS, int PRINT_FRAME)
109
The inferior has stopped for real. The BS argument describes the
110
breakpoints were are stopped at, if any. Second argument
111
PRINT_FRAME non-zero means display the location where the inferior
114
-- Function: void target_changed (struct target_ops *TARGET)
115
The target's register contents have changed.
117
-- Function: void executable_changed (void)
118
The executable being debugged by GDB has changed: The user decided
119
to debug a different program, or the program he was debugging has
120
been modified since being loaded by the debugger (by being
121
recompiled, for instance).
123
-- Function: void inferior_created (struct target_ops *OBJFILE, int
125
GDB has just connected to an inferior. For `run', GDB calls this
126
observer while the inferior is still stopped at the entry-point
127
instruction. For `attach' and `core', GDB calls this observer
128
immediately after connecting to the inferior, and before any
129
information on the inferior has been printed.
131
-- Function: void solib_loaded (struct so_list *SOLIB)
132
The shared library specified by SOLIB has been loaded. Note that
133
when GDB calls this observer, the library's symbols probably
134
haven't been loaded yet.
136
-- Function: void solib_unloaded (struct so_list *SOLIB)
137
The shared library specified by SOLIB has been unloaded. Note
138
that when GDB calls this observer, the library's symbols have not
139
been unloaded yet, and thus are still available.
141
-- Function: void new_objfile (struct objfile *OBJFILE)
142
The symbol file specified by OBJFILE has been loaded. Called with
143
OBJFILE equal to `NULL' to indicate previously loaded symbol table
144
data has now been invalidated.
146
-- Function: void new_thread (struct thread_info *T)
147
The thread specified by T has been created.
149
-- Function: void thread_exit (struct thread_info *T, int SILENT)
150
The thread specified by T has exited. The SILENT argument
151
indicates that GDB is removing the thread from its tables without
152
wanting to notify the user about it.
154
-- Function: void thread_stop_requested (ptid_t PTID)
155
An explicit stop request was issued to PTID. If PTID equals
156
MINUS_ONE_PTID, the request applied to all threads. If
157
`ptid_is_pid(ptid)' returns true, the request applied to all
158
threads of the process pointed at by PTID. Otherwise, the request
159
applied to the single thread pointed at by PTID.
161
-- Function: void target_resumed (ptid_t PTID)
162
The target was resumed. The PTID parameter specifies which thread
163
was resume, and may be RESUME_ALL if all threads are resumed.
165
-- Function: void about_to_proceed (void)
166
The target is about to be proceeded.
168
-- Function: void breakpoint_created (struct breakpoint *B)
169
A new breakpoint B has been created.
171
-- Function: void breakpoint_deleted (struct breakpoint *B)
172
A breakpoint has been destroyed. The argument B is the pointer to
173
the destroyed breakpoint.
175
-- Function: void breakpoint_modified (struct breakpoint *B)
176
A breakpoint has been modified in some way. The argument B is the
179
-- Function: void tracepoint_created (int TPNUM)
180
A new tracepoint has been created. The argument TPNUM is the
181
number of the newly-created tracepoint.
183
-- Function: void tracepoint_deleted (int TPNUM)
184
A tracepoint has been destroyed. The argument TPNUM is the number
185
of the newly-destroyed tracepoint.
187
-- Function: void tracepoint_modified (int TPNUM)
188
A tracepoint has been modified in some way. The argument TPNUM is
189
the number of the modified tracepoint.
191
-- Function: void architecture_changed (struct gdbarch *NEWARCH)
192
The current architecture has changed. The argument NEWARCH is a
193
pointer to the new architecture.
195
-- Function: void thread_ptid_changed (ptid_t OLD_PTID, ptid_t
197
The thread's ptid has changed. The OLD_PTID parameter specifies
198
the old value, and NEW_PTID specifies the new value.
200
-- Function: void inferior_added (struct inferior *INF)
201
The inferior INF has been added to the list of inferiors. At this
202
point, it might not be associated with any process.
204
-- Function: void inferior_appeared (struct inferior *INF)
205
The inferior identified by INF has been attached to a process.
207
-- Function: void inferior_exit (struct inferior *INF)
208
Either the inferior associated with INF has been detached from the
209
process, or the process has exited.
211
-- Function: void inferior_removed (struct inferior *INF)
212
The inferior INF has been removed from the list of inferiors.
213
This method is called immediately before freeing INF.
215
-- Function: void memory_changed (CORE_ADDR ADDR, int LEN, const
217
Bytes from DATA to DATA + LEN have been written to the current
220
-- Function: void before_prompt (const char *CURRENT_PROMPT)
221
Called before a top-level prompt is displayed. CURRENT_PROMPT is
222
the current top-level prompt.
224
-- Function: void test_notification (int SOMEARG)
225
This observer is used for internal testing. Do not use. See
226
testsuite/gdb.gdb/observer.exp.

Version 1.3, 3 November 2008
236
Copyright (C) 2000, 2001, 2002, 2007, 2008 Free Software Foundation, Inc.
239
Everyone is permitted to copy and distribute verbatim copies
240
of this license document, but changing it is not allowed.
244
The purpose of this License is to make a manual, textbook, or other
245
functional and useful document "free" in the sense of freedom: to
246
assure everyone the effective freedom to copy and redistribute it,
247
with or without modifying it, either commercially or
248
noncommercially. Secondarily, this License preserves for the
249
author and publisher a way to get credit for their work, while not
250
being considered responsible for modifications made by others.
252
This License is a kind of "copyleft", which means that derivative
253
works of the document must themselves be free in the same sense.
254
It complements the GNU General Public License, which is a copyleft
255
license designed for free software.
257
We have designed this License in order to use it for manuals for
258
free software, because free software needs free documentation: a
259
free program should come with manuals providing the same freedoms
260
that the software does. But this License is not limited to
261
software manuals; it can be used for any textual work, regardless
262
of subject matter or whether it is published as a printed book.
263
We recommend this License principally for works whose purpose is
264
instruction or reference.
266
1. APPLICABILITY AND DEFINITIONS
268
This License applies to any manual or other work, in any medium,
269
that contains a notice placed by the copyright holder saying it
270
can be distributed under the terms of this License. Such a notice
271
grants a world-wide, royalty-free license, unlimited in duration,
272
to use that work under the conditions stated herein. The
273
"Document", below, refers to any such manual or work. Any member
274
of the public is a licensee, and is addressed as "you". You
275
accept the license if you copy, modify or distribute the work in a
276
way requiring permission under copyright law.
278
A "Modified Version" of the Document means any work containing the
279
Document or a portion of it, either copied verbatim, or with
280
modifications and/or translated into another language.
282
A "Secondary Section" is a named appendix or a front-matter section
283
of the Document that deals exclusively with the relationship of the
284
publishers or authors of the Document to the Document's overall
285
subject (or to related matters) and contains nothing that could
286
fall directly within that overall subject. (Thus, if the Document
287
is in part a textbook of mathematics, a Secondary Section may not
288
explain any mathematics.) The relationship could be a matter of
289
historical connection with the subject or with related matters, or
290
of legal, commercial, philosophical, ethical or political position
293
The "Invariant Sections" are certain Secondary Sections whose
294
titles are designated, as being those of Invariant Sections, in
295
the notice that says that the Document is released under this
296
License. If a section does not fit the above definition of
297
Secondary then it is not allowed to be designated as Invariant.
298
The Document may contain zero Invariant Sections. If the Document
299
does not identify any Invariant Sections then there are none.
301
The "Cover Texts" are certain short passages of text that are
302
listed, as Front-Cover Texts or Back-Cover Texts, in the notice
303
that says that the Document is released under this License. A
304
Front-Cover Text may be at most 5 words, and a Back-Cover Text may
307
A "Transparent" copy of the Document means a machine-readable copy,
308
represented in a format whose specification is available to the
309
general public, that is suitable for revising the document
310
straightforwardly with generic text editors or (for images
311
composed of pixels) generic paint programs or (for drawings) some
312
widely available drawing editor, and that is suitable for input to
313
text formatters or for automatic translation to a variety of
314
formats suitable for input to text formatters. A copy made in an
315
otherwise Transparent file format whose markup, or absence of
316
markup, has been arranged to thwart or discourage subsequent
317
modification by readers is not Transparent. An image format is
318
not Transparent if used for any substantial amount of text. A
319
copy that is not "Transparent" is called "Opaque".
321
Examples of suitable formats for Transparent copies include plain
322
ASCII without markup, Texinfo input format, LaTeX input format,
323
SGML or XML using a publicly available DTD, and
324
standard-conforming simple HTML, PostScript or PDF designed for
325
human modification. Examples of transparent image formats include
326
PNG, XCF and JPG. Opaque formats include proprietary formats that
327
can be read and edited only by proprietary word processors, SGML or
328
XML for which the DTD and/or processing tools are not generally
329
available, and the machine-generated HTML, PostScript or PDF
330
produced by some word processors for output purposes only.
332
The "Title Page" means, for a printed book, the title page itself,
333
plus such following pages as are needed to hold, legibly, the
334
material this License requires to appear in the title page. For
335
works in formats which do not have any title page as such, "Title
336
Page" means the text near the most prominent appearance of the
337
work's title, preceding the beginning of the body of the text.
339
The "publisher" means any person or entity that distributes copies
340
of the Document to the public.
342
A section "Entitled XYZ" means a named subunit of the Document
343
whose title either is precisely XYZ or contains XYZ in parentheses
344
following text that translates XYZ in another language. (Here XYZ
345
stands for a specific section name mentioned below, such as
346
"Acknowledgements", "Dedications", "Endorsements", or "History".)
347
To "Preserve the Title" of such a section when you modify the
348
Document means that it remains a section "Entitled XYZ" according
351
The Document may include Warranty Disclaimers next to the notice
352
which states that this License applies to the Document. These
353
Warranty Disclaimers are considered to be included by reference in
354
this License, but only as regards disclaiming warranties: any other
355
implication that these Warranty Disclaimers may have is void and
356
has no effect on the meaning of this License.
360
You may copy and distribute the Document in any medium, either
361
commercially or noncommercially, provided that this License, the
362
copyright notices, and the license notice saying this License
363
applies to the Document are reproduced in all copies, and that you
364
add no other conditions whatsoever to those of this License. You
365
may not use technical measures to obstruct or control the reading
366
or further copying of the copies you make or distribute. However,
367
you may accept compensation in exchange for copies. If you
368
distribute a large enough number of copies you must also follow
369
the conditions in section 3.
371
You may also lend copies, under the same conditions stated above,
372
and you may publicly display copies.
374
3. COPYING IN QUANTITY
376
If you publish printed copies (or copies in media that commonly
377
have printed covers) of the Document, numbering more than 100, and
378
the Document's license notice requires Cover Texts, you must
379
enclose the copies in covers that carry, clearly and legibly, all
380
these Cover Texts: Front-Cover Texts on the front cover, and
381
Back-Cover Texts on the back cover. Both covers must also clearly
382
and legibly identify you as the publisher of these copies. The
383
front cover must present the full title with all words of the
384
title equally prominent and visible. You may add other material
385
on the covers in addition. Copying with changes limited to the
386
covers, as long as they preserve the title of the Document and
387
satisfy these conditions, can be treated as verbatim copying in
390
If the required texts for either cover are too voluminous to fit
391
legibly, you should put the first ones listed (as many as fit
392
reasonably) on the actual cover, and continue the rest onto
395
If you publish or distribute Opaque copies of the Document
396
numbering more than 100, you must either include a
397
machine-readable Transparent copy along with each Opaque copy, or
398
state in or with each Opaque copy a computer-network location from
399
which the general network-using public has access to download
400
using public-standard network protocols a complete Transparent
401
copy of the Document, free of added material. If you use the
402
latter option, you must take reasonably prudent steps, when you
403
begin distribution of Opaque copies in quantity, to ensure that
404
this Transparent copy will remain thus accessible at the stated
405
location until at least one year after the last time you
406
distribute an Opaque copy (directly or through your agents or
407
retailers) of that edition to the public.
409
It is requested, but not required, that you contact the authors of
410
the Document well before redistributing any large number of
411
copies, to give them a chance to provide you with an updated
412
version of the Document.
416
You may copy and distribute a Modified Version of the Document
417
under the conditions of sections 2 and 3 above, provided that you
418
release the Modified Version under precisely this License, with
419
the Modified Version filling the role of the Document, thus
420
licensing distribution and modification of the Modified Version to
421
whoever possesses a copy of it. In addition, you must do these
422
things in the Modified Version:
424
A. Use in the Title Page (and on the covers, if any) a title
425
distinct from that of the Document, and from those of
426
previous versions (which should, if there were any, be listed
427
in the History section of the Document). You may use the
428
same title as a previous version if the original publisher of
429
that version gives permission.
431
B. List on the Title Page, as authors, one or more persons or
432
entities responsible for authorship of the modifications in
433
the Modified Version, together with at least five of the
434
principal authors of the Document (all of its principal
435
authors, if it has fewer than five), unless they release you
436
from this requirement.
438
C. State on the Title page the name of the publisher of the
439
Modified Version, as the publisher.
441
D. Preserve all the copyright notices of the Document.
443
E. Add an appropriate copyright notice for your modifications
444
adjacent to the other copyright notices.
446
F. Include, immediately after the copyright notices, a license
447
notice giving the public permission to use the Modified
448
Version under the terms of this License, in the form shown in
451
G. Preserve in that license notice the full lists of Invariant
452
Sections and required Cover Texts given in the Document's
455
H. Include an unaltered copy of this License.
457
I. Preserve the section Entitled "History", Preserve its Title,
458
and add to it an item stating at least the title, year, new
459
authors, and publisher of the Modified Version as given on
460
the Title Page. If there is no section Entitled "History" in
461
the Document, create one stating the title, year, authors,
462
and publisher of the Document as given on its Title Page,
463
then add an item describing the Modified Version as stated in
464
the previous sentence.
466
J. Preserve the network location, if any, given in the Document
467
for public access to a Transparent copy of the Document, and
468
likewise the network locations given in the Document for
469
previous versions it was based on. These may be placed in
470
the "History" section. You may omit a network location for a
471
work that was published at least four years before the
472
Document itself, or if the original publisher of the version
473
it refers to gives permission.
475
K. For any section Entitled "Acknowledgements" or "Dedications",
476
Preserve the Title of the section, and preserve in the
477
section all the substance and tone of each of the contributor
478
acknowledgements and/or dedications given therein.
480
L. Preserve all the Invariant Sections of the Document,
481
unaltered in their text and in their titles. Section numbers
482
or the equivalent are not considered part of the section
485
M. Delete any section Entitled "Endorsements". Such a section
486
may not be included in the Modified Version.
488
N. Do not retitle any existing section to be Entitled
489
"Endorsements" or to conflict in title with any Invariant
492
O. Preserve any Warranty Disclaimers.
494
If the Modified Version includes new front-matter sections or
495
appendices that qualify as Secondary Sections and contain no
496
material copied from the Document, you may at your option
497
designate some or all of these sections as invariant. To do this,
498
add their titles to the list of Invariant Sections in the Modified
499
Version's license notice. These titles must be distinct from any
500
other section titles.
502
You may add a section Entitled "Endorsements", provided it contains
503
nothing but endorsements of your Modified Version by various
504
parties--for example, statements of peer review or that the text
505
has been approved by an organization as the authoritative
506
definition of a standard.
508
You may add a passage of up to five words as a Front-Cover Text,
509
and a passage of up to 25 words as a Back-Cover Text, to the end
510
of the list of Cover Texts in the Modified Version. Only one
511
passage of Front-Cover Text and one of Back-Cover Text may be
512
added by (or through arrangements made by) any one entity. If the
513
Document already includes a cover text for the same cover,
514
previously added by you or by arrangement made by the same entity
515
you are acting on behalf of, you may not add another; but you may
516
replace the old one, on explicit permission from the previous
517
publisher that added the old one.
519
The author(s) and publisher(s) of the Document do not by this
520
License give permission to use their names for publicity for or to
521
assert or imply endorsement of any Modified Version.
523
5. COMBINING DOCUMENTS
525
You may combine the Document with other documents released under
526
this License, under the terms defined in section 4 above for
527
modified versions, provided that you include in the combination
528
all of the Invariant Sections of all of the original documents,
529
unmodified, and list them all as Invariant Sections of your
530
combined work in its license notice, and that you preserve all
531
their Warranty Disclaimers.
533
The combined work need only contain one copy of this License, and
534
multiple identical Invariant Sections may be replaced with a single
535
copy. If there are multiple Invariant Sections with the same name
536
but different contents, make the title of each such section unique
537
by adding at the end of it, in parentheses, the name of the
538
original author or publisher of that section if known, or else a
539
unique number. Make the same adjustment to the section titles in
540
the list of Invariant Sections in the license notice of the
543
In the combination, you must combine any sections Entitled
544
"History" in the various original documents, forming one section
545
Entitled "History"; likewise combine any sections Entitled
546
"Acknowledgements", and any sections Entitled "Dedications". You
547
must delete all sections Entitled "Endorsements."
549
6. COLLECTIONS OF DOCUMENTS
551
You may make a collection consisting of the Document and other
552
documents released under this License, and replace the individual
553
copies of this License in the various documents with a single copy
554
that is included in the collection, provided that you follow the
555
rules of this License for verbatim copying of each of the
556
documents in all other respects.
558
You may extract a single document from such a collection, and
559
distribute it individually under this License, provided you insert
560
a copy of this License into the extracted document, and follow
561
this License in all other respects regarding verbatim copying of
564
7. AGGREGATION WITH INDEPENDENT WORKS
566
A compilation of the Document or its derivatives with other
567
separate and independent documents or works, in or on a volume of
568
a storage or distribution medium, is called an "aggregate" if the
569
copyright resulting from the compilation is not used to limit the
570
legal rights of the compilation's users beyond what the individual
571
works permit. When the Document is included in an aggregate, this
572
License does not apply to the other works in the aggregate which
573
are not themselves derivative works of the Document.
575
If the Cover Text requirement of section 3 is applicable to these
576
copies of the Document, then if the Document is less than one half
577
of the entire aggregate, the Document's Cover Texts may be placed
578
on covers that bracket the Document within the aggregate, or the
579
electronic equivalent of covers if the Document is in electronic
580
form. Otherwise they must appear on printed covers that bracket
585
Translation is considered a kind of modification, so you may
586
distribute translations of the Document under the terms of section
587
4. Replacing Invariant Sections with translations requires special
588
permission from their copyright holders, but you may include
589
translations of some or all Invariant Sections in addition to the
590
original versions of these Invariant Sections. You may include a
591
translation of this License, and all the license notices in the
592
Document, and any Warranty Disclaimers, provided that you also
593
include the original English version of this License and the
594
original versions of those notices and disclaimers. In case of a
595
disagreement between the translation and the original version of
596
this License or a notice or disclaimer, the original version will
599
If a section in the Document is Entitled "Acknowledgements",
600
"Dedications", or "History", the requirement (section 4) to
601
Preserve its Title (section 1) will typically require changing the
606
You may not copy, modify, sublicense, or distribute the Document
607
except as expressly provided under this License. Any attempt
608
otherwise to copy, modify, sublicense, or distribute it is void,
609
and will automatically terminate your rights under this License.
611
However, if you cease all violation of this License, then your
612
license from a particular copyright holder is reinstated (a)
613
provisionally, unless and until the copyright holder explicitly
614
and finally terminates your license, and (b) permanently, if the
615
copyright holder fails to notify you of the violation by some
616
reasonable means prior to 60 days after the cessation.
618
Moreover, your license from a particular copyright holder is
619
reinstated permanently if the copyright holder notifies you of the
620
violation by some reasonable means, this is the first time you have
621
received notice of violation of this License (for any work) from
622
that copyright holder, and you cure the violation prior to 30 days
623
after your receipt of the notice.
625
Termination of your rights under this section does not terminate
626
the licenses of parties who have received copies or rights from
627
you under this License. If your rights have been terminated and
628
not permanently reinstated, receipt of a copy of some or all of
629
the same material does not give you any rights to use it.
631
10. FUTURE REVISIONS OF THIS LICENSE
633
The Free Software Foundation may publish new, revised versions of
634
the GNU Free Documentation License from time to time. Such new
635
versions will be similar in spirit to the present version, but may
636
differ in detail to address new problems or concerns. See
637
`http://www.gnu.org/copyleft/'.
639
Each version of the License is given a distinguishing version
640
number. If the Document specifies that a particular numbered
641
version of this License "or any later version" applies to it, you
642
have the option of following the terms and conditions either of
643
that specified version or of any later version that has been
644
published (not as a draft) by the Free Software Foundation. If
645
the Document does not specify a version number of this License,
646
you may choose any version ever published (not as a draft) by the
647
Free Software Foundation. If the Document specifies that a proxy
648
can decide which future versions of this License can be used, that
649
proxy's public statement of acceptance of a version permanently
650
authorizes you to choose that version for the Document.
654
"Massive Multiauthor Collaboration Site" (or "MMC Site") means any
655
World Wide Web server that publishes copyrightable works and also
656
provides prominent facilities for anybody to edit those works. A
657
public wiki that anybody can edit is an example of such a server.
658
A "Massive Multiauthor Collaboration" (or "MMC") contained in the
659
site means any set of copyrightable works thus published on the MMC
662
"CC-BY-SA" means the Creative Commons Attribution-Share Alike 3.0
663
license published by Creative Commons Corporation, a not-for-profit
664
corporation with a principal place of business in San Francisco,
665
California, as well as future copyleft versions of that license
666
published by that same organization.
668
"Incorporate" means to publish or republish a Document, in whole or
669
in part, as part of another Document.
671
An MMC is "eligible for relicensing" if it is licensed under this
672
License, and if all works that were first published under this
673
License somewhere other than this MMC, and subsequently
674
incorporated in whole or in part into the MMC, (1) had no cover
675
texts or invariant sections, and (2) were thus incorporated prior
678
The operator of an MMC Site may republish an MMC contained in the
679
site under CC-BY-SA on the same site at any time before August 1,
680
2009, provided the MMC is eligible for relicensing.
