+# Fedora GDB local patches policy
+
+In order to make things easier for the Fedora GDB maintainer, we
+choose to auto-generate the local patches by making use of an upstream
+git repository.  Below you can find a few instructions on how to work
+using this method.
+
+You need to run the following commands from the directory that
+contains the "gdb.spec" file.
+
+## Importing the GDB patches into a git repository
+
+1) The local patches (`*.patch`) need to be imported into an upstream
+git repository.  For example, let's assume you cloned the repository
+by doing:
+
+`$ git clone git://sourceware.org/git/binutils-gdb.git`
+
+> TIP: if you already have the repository cloned somewhere in your
+> system, you can pass a "--reference <dir>" to the "git clone"
+> command and it will use your local repository as much as possible
+> to make the clone, speeding up things.
+
+2) After cloning the upstream repository, you can import your patches
+by using the script "generate-git-repo-from-patches.sh":
+
+`$ sh generate-git-repo-from-patches.sh <REPOSITORY_DIR>`
+
+The script will basically cd into the repository, checkout the
+revision specified in the file `_git_upstream_commit`, iterate through
+the file `_patch_order` and "git-am" every patch *in that order*.
+This operation should complete without errors; if you find a problem
+with `git-am`, it probably means that the revision specified in the
+file `_git_upstream_commit` is wrong.
+
+## Rebasing the patches against a newer version/release
+
+1) First, cd into the upstream repository.  All you have to do is
+choose the revision against which you plan to rebase the patches, and
+`git rebase <REVISION>`.  git will do the rest, and you will be able
+to perform conflict resolution by git's algorithm, which is smarter.
+
+## Creating new patches
+
+1) Create the new patch on top of the the others, as usual.  Note that
+you can use `git rebase` whenever you want to reorder patch order, or
+even to delete a patch.
+
+2) When writing the commit log, you must obey a few rules.  The
+subject line *must* be the filename of the patch.  This line will be
+used when exporting the patches from the git repository, and
+(obviously) it gives the filename that should be used for this
+specific patch.
+
+3) You can also add comments that will go into the auto-generated
+`Patch:` file (see below).  To do that, use the special marker `;;` at
+the beginning of the line.  This way, a commit log that says:
+
+~~~~~~~~~~~
+  test-patch.patch
+
+  ;; This is a test patch
+  ;; Second line
+~~~~~~~~~~~
+
+Will generate the following entry in the auto-generated `Patch:` file:
+
+~~~~~~~~~~~
+  # This is a test patch
+  # Second line
+  PatchXYZ: test-patch.patch
+~~~~~~~~~~~
+
+## Exporting the GDB patches from the git repository
+
+1) When you're done working with the patches, go back to the directory
+that contains the `gdb.spec` file, and from there you run:
+
+`$ sh generate-patches-from-git-repo.sh <REPOSITORY_DIR>`
+
+This will regenerate all of the `*.patch` files (excluding the ones that
+were also excluded from the git repository), and also regenerate a few
+control files.  These control files are:
+
+  - `_gdb.spec.Patch.include`: This file contains the `Patch:` directives.
+
+  - `_gdb.spec.patch.include`: This file contains the `%patch` directives.
+
+  - `_patch_order`: This file contains the patches, in the exact order
+    that they must be applied.  It is used when importing the patches
+    into the git repository.
+
+  - `_git_upstream_commit`: This file contains the last upstream commit
+    against which the patches were rebased.  It is used when importing
+    the patches into the git repository.
+
+NOTE: If you did a rebase against a newer upstream version, you need
+to specify the commit/tag/branch against which you rebased:
+
+`$ sh generate-patches-from-git-repo.sh <REPOSITORY_DIR> <COMMIT_OR_TAG_OR_BRANCH>`
+
+For example, if you rebased against `gdb-8.1-release`:
+
+`$ sh generate-patches-from-git-repo.sh <REPOSITORY_DIR> gdb-8.1-release`

++ * The point of this program is to crash in a multi-threaded app.
++ * There are seven threads, doing the following things:
++ * * Spinning
++ * * Spinning inside a signal handler
++ * * Spinning inside a signal handler executing on the altstack
++ * * In a syscall
++ * * In a syscall inside a signal handler
++ * * In a syscall inside a signal handler executing on the altstack
++ * * Finally, the main thread crashes in main, with no frills.
++ *
++ * These are the things threads in JRockit tend to be doing.  If gdb
++ * can handle those things, both in core files and during live
++ * debugging, that will help (at least) JRockit development.
++ *
++ * Let the program create a core file, then load the core file into
++ * gdb.  Inside gdb, you should be able to do something like this:
++ *
++ * (gdb) t a a bt

+Subject: gdb-6.5-bz185337-resolve-tls-without-debuginfo-v2.patch

+;; Support TLS symbols (+`errno' suggestion if no pthread is found) (BZ 185337).

+

+
+2008-02-24  Jan Kratochvil  <jan.kratochvil@redhat.com>
+
+	Port to GDB-6.8pre.
+
+currently for trivial nonthreaded helloworld with no debug info up to -ggdb2 you
+will get:
+        (gdb) p errno
+        [some error]
+
+* with -ggdb2 and less "errno" in fact does not exist anywhere as it was
+  compiled to "(*__errno_location ())" and the macro definition is not present.
+  Unfortunately gdb will find the TLS symbol and it will try to access it but
+  as the program has been compiled without -lpthread the TLS base register
+  (%gs on i386) is not setup and it will result in:
+        Cannot access memory at address 0x8
+
+Attached suggestion patch how to deal with the most common "errno" symbol
+for the most common under-ggdb3 compiled programs.
+
+Original patch hooked into target_translate_tls_address.  But its inferior
+call invalidates `struct frame *' in the callers - RH BZ 690908.

+
+While thinking about it overriding some GDB _commands_ was not my intention.
+
+There is a general assumption if I have a shell COMMAND and some FILE I can do
+$ COMMAND FILE
+and COMMAND will appropriately load the FILE.
+
+FSF GDB currently needs to specify also the executable file for core files
+which already inhibits this intuitive expectation.  OTOH with the build-id
+locating patch which could allow such intuitive start  notneeding the
+executable file.  Still it currently did not work due to the required "-c":
+$ COMMAND -c COREFILE
+
+Entering "file", "core-file" or "attach" commands is already explicit enough
+so that it IMO should do what the command name says without any
+autodetections.  The second command line argument
+(captured_main->pid_or_core_arg) is also autodetected (for PID or CORE) but
+neither "attach" accepts a core file nor "core-file" accepts a PID.
+
+The patch makes sense only with the build-id patchset so this is not submit
+for FSF GDB inclusion yet.  I am fine with your patch (+/- Hui Zhu's pending
+bfd_check_format_matches) as the patch below is its natural extension.

+;;=push+jan
+
+Comments by Sergio Durigan Junior <sergiodj@redhat.com>:
+
+  This is the fix for RH BZ #981154
+
+  It is mainly a testcase addition, but a minor fix in the gdb/build-id.c
+  file was also needed.
+
+  gdb/build-id.c was added by:
+
+  commit dc294be54c96414035eed7d53dafdea0a6f31a72
+  Author: Tom Tromey <tromey@redhat.com>
+  Date:   Tue Oct 8 19:56:15 2013 +0000
+
+  and had a little thinko there.  The variable 'filename' needs to be set to
+  NULL after it is free'd, otherwise the code below thinks that it is still
+  valid and doesn't print the necessary warning ("Try: yum install ...").

+;; Make the GDB quit processing non-abortable to cleanup everything properly.
+;;=fedora: It was useful only after gdb-6.8-attach-signalled-detach-stopped.patch .
+
+We may abort the process of detaching threads with multiple SIGINTs - which are
+being sent during a testcase terminating its child GDB.
+
+Some of the threads may not be properly PTRACE_DETACHed which hurts if they
+should have been detached with SIGSTOP (as they are accidentally left running
+on the debugger termination).

+
+Hi,
+
+in some cases with deleted main executable GDB will want to kill the inferior.
+
+$ cp /bin/sleep /tmp/sleep;/tmp/sleep 1h&p=$!
+$ rm /tmp/sleep
+$ gdb /tmp/sleep $p
+GNU gdb (GDB) 7.10.50.20151016-cvs
+/tmp/sleep: No such file or directory.
+Attaching to process 9694
+/tmp/sleep (deleted): No such file or directory.
+A program is being debugged already.  Kill it? (y or n) _
+
+The first attachment of "/tmp/sleep" commandline argument errors at:
+
+267               if (scratch_chan < 0)
+268                 perror_with_name (filename);
+1051          if (catch_command_errors_const (exec_file_attach, execarg,
+1052                                          !batch_flag))
+
+Then GDB tries to attach to the process $p:
+
+1082              if (catch_command_errors (attach_command, pid_or_core_arg,
+1083                                        !batch_flag) == 0)
+
+This succeeds and since this moment GDB has a valid inferior.  But despite that
+the lines
+1082              if (catch_command_errors (attach_command, pid_or_core_arg,
+1083                                        !batch_flag) == 0)
+still fail because consequently attach_command() fails to find the associated
+executable file:
+
+267               if (scratch_chan < 0)
+268                 perror_with_name (filename);
+1082              if (catch_command_errors (attach_command, pid_or_core_arg,
+1083                                        !batch_flag) == 0)
+
+and therefore GDB executes the following:
+
+(gdb) bt
+2179	  if (have_inferiors ())
+2180	    {
+2181	      if (!from_tty
+2182		  || !have_live_inferiors ()
+2183		  || query (_("A program is being debugged already.  Kill it? ")))
+2184		iterate_over_inferiors (dispose_inferior, NULL);
+2185	      else
+2186		error (_("Program not killed."));
+2187	    }
+1084		    catch_command_errors (core_file_command, pid_or_core_arg,
+1085					  !batch_flag);
+
+No regressions on {x86_64,x86_64-m32,i686}-fedora24pre-linux-gnu.

+Subject: gdb-bz533176-fortran-omp-step.patch
+
+;; Fix stepping with OMP parallel Fortran sections (BZ 533176).
+;;=push+jan: It requires some better DWARF annotations.
+
+https://bugzilla.redhat.com/show_bug.cgi?id=533176#c4
+
+I find it a bug in DWARF and gdb behaves correctly according to it.  From the
+current DWARF's point of view the is a function call which you skip by "next".
+
+If you hide any /usr/lib/debug such as using:
+gdb -nx -ex 'set debug-file-directory /qwe' -ex 'file ./tpcommon_gfortran44'
+and use "step" command instead of "next" there it will work.
+(You need to hide debuginfo from libgomp as you would step into libgomp sources
+to maintain the threads for execution.)
+
+There should be some DWARF extension for it, currently tried to detect
+substring ".omp_fn." as this function is called "MAIN__.omp_fn.0" and do not
+consider such sub-function as a skippable by "next".
+
+Another problem is that with "set scheduler-locking" being "off" (default
+upstream) or "step" (default in F/RHEL) the simultaneous execution of the
+threads is inconvenient.  Setting it to "on" will lockup the debugging as the
+threads need to get synchronized at some point.  This is a more general
+debugging problem of GOMP outside of the scope of this Bug.

+There is a bug in that entry value code of mine, fix attached.
+The testcase then PASSes with the reverted optimization by Andrew Burgess.
+
+For the attached fix - if you nitpick the missing conditional case:
+	value_optimized_out (val_deref) && value_optimized_out (entryval_deref)
+It is not detected there but that IMO does not matter much as
+ * It is for 7.8 only, for trunk it will get compared correctly thanks to the
+   new implementation of value_available_contents_eq()
+   called value_contents_eq().
+ * If the conditional
+                      if (val != val_deref
+                          && !value_optimized_out (val_deref)
+                          && !value_optimized_out (entryval_deref)
+                          && value_available_contents_eq (val_deref, 0,
+                                                          entryval_deref, 0,
+                                                      TYPE_LENGTH (type_deref)))
+                        val_equal = 1;
+   fails it may just print
+     bar (ref=@0x7fffffffd904: <optimized out>, ref@entry=@0x7fffffffd904: <optimized out>)
+   (or some variant with some partially optimized-out/unavailable parts)
+   instead of the more correct
+     bar (ref=ref@entry=@0x7fffffffd904: <optimized out>)
+   which is not much a bug.
+
+The attached fix no longe makes sense after the new implementation
+of value_available_contents_eq() called value_contents_eq() gets applied as it
+handles all the optimized-out/unavailable values on its own, therefore the
+attached patch is really only for 7.8.

+
+I cannot reproduce any wrong case having the code above #if 0-ed.
+
+I just do not find it correct to have it disabled.  But at the same time I do
+like much / I do not find correct the code myself.  It is a bit problematic to
+have struct value describing a memory content which is no longer present
+there.
+
+What happens there:
+------------------------------------------------------------------------------
+volatile int vv;
+static __attribute__((noinline)) int
+bar (int &ref) {
+  ref = 20;
+  vv++; /* break-here */
+  return ref;
+}
+int main (void) {

+  return bar (var);

+gdb -ex 'b value_addr' -ex r --args ../gdb ./1 -ex 'watch vv' -ex r -ex 'p &ref@entry'
+->
+6    return ref;
+bar (ref=@0x7fffffffd944: 20, ref@entry=@0x7fffffffd944: 10) at 1.C:25
+------------------------------------------------------------------------------
+At /* break-here */ struct value variable 'ref' is TYPE_CODE_REF.
+
+With FSF GDB HEAD:
+(gdb) x/gx arg1.contents
+0x6004000a4ad0: 0x00007fffffffd944
+(gdb) p ((struct value *)arg1.location.computed.closure).lval
+$1 = lval_memory
+(gdb) p/x ((struct value *)arg1.location.computed.closure).location.address
+$3 = 0x7fffffffd944
+
+With your #if0-ed code:
+(gdb) x/gx arg1.contents
+0x6004000a4ad0: 0x00007fffffffd944
+(gdb) p ((struct value *)arg1.location.computed.closure).lval
+$8 = not_lval
+(gdb) p/x ((struct value *)arg1.location.computed.closure).location.address
+$9 = 0x0
+
+I do not see how to access
+	((struct value *)arg1.location.computed.closure).location.address
+from GDB CLI.  Trying
+(gdb) p &ref@entry
+will invoke value_addr()'s:
+  if (TYPE_CODE (type) == TYPE_CODE_REF)
+      /* Copy the value, but change the type from (T&) to (T*).  We
+         keep the same location information, which is efficient, and
+         allows &(&X) to get the location containing the reference.  */
+and therefore the address gets fetched already from
+  arg1.contents
+and not from
+  ((struct value *)arg1.location.computed.closure).location.address
+.
+
+And for any other type than TYPE_CODE_REF this code you #if 0-ed does not get
+executed at all.  This DW_AT_GNU_call_site_data_value DWARF was meant
+primarily for Fortran but with -O0 entry values do not get produced
+and with -Og and higher Fortran always optimizes out the passing by reference.
+
+If you do not like the #if 0 code there I am OK with removing it as I do not
+know how to make it's use reproducible for user anyway.  In the worst case
+- if there really is some way how to exploit it - one should just get
+  Attempt to take address of value not located in memory.
+instead of some wrong value and it may be easy to fix then.
+
+
+Thanks for the analysis,
+Jan

+
+Hi,
+
+for Fortran it fixes displaying normal strings also in frames/backtraces:
+
+(gdb) frame
+->
+
+The patch is simple and I do not see why it should not be this way.
+
+For C/C++ TYPE_CODE_STRING is not used.  I am not aware of Pascal but that
+language is currently not really much supported in GDB anyway.
+
+This was a part of my archer/jankratochvil/vla branch but it is not a part of
+the Intel VLA patchset as it in fact is completely unrelated to "VLA".
+
+No regressions on {x86_64,x86_64-m32,i686}-fedora22pre-linux-gnu.
+
+Thanks,
+Jan

+Hi,
+
+PR 16581:
+	GDB crash on inherit_abstract_dies infinite recursion
+	https://sourceware.org/bugzilla/show_bug.cgi?id=16581
+
+fixed crash from an infinite recursion.  But in rare cases the new code can
+now gdb_assert() due to weird DWARF file.
+
+I do not yet fully understand why the DWARF is as it is but just GDB should
+never crash due to invalid DWARF anyway.  The "invalid" DWARF I see only in
+Fedora GCC build, not in FSF GCC build, more info at:

+gstack \- print a stack trace of a running process
+
+.SH SYNOPSIS
+.B gstack
+pid
+
+.SH DESCRIPTION
+
+\f3gstack\f1 attaches to the active process named by the \f3pid\f1 on
+the command line, and prints out an execution stack trace.  If ELF
+symbols exist in the binary (usually the case unless you have run
+strip(1)), then symbolic addresses are printed as well.
+
+If the process is part of a thread group, then \f3gstack\f1 will print
+out a stack trace for each of the threads in the group.

+;; Fix 'memory leak in infpy_read_memory()' (RH BZ 1007614)

+Original message by Tom Tromey:
+
+  <https://sourceware.org/ml/gdb-patches/2012-03/msg00955.html>
+  Message-ID: <871uoc1va3.fsf@fleche.redhat.com>
+
+Comment from Sergio Durigan Junior:
+
+  In order to correctly test this patch, I wrote a testcase based on Jan
+  Kratochvil's <gdb/testsuite/gdb.base/gcore-excessive-memory.exp>.  The
+  testcase, which can be seen below, tests GDB in order to see if the
+  amount of memory being leaked is minimal, as requested in the bugzilla.
+  It is hard to define what "minimum" is, so I ran the testcase on all
+  supported RHEL architectures and came up with an average.

+Subject: gdb-rhbz1084404-ppc64-s390x-wrong-prologue-skip-O2-g-3of3.patch
+
+;; Fix '[ppc64] and [s390x] wrong prologue skip on -O2 -g code' (Jan
+;; Kratochvil, RH BZ 1084404).
+;;=fedoratest
+
+These testcases have been created by compiling glibc-2.17-78 on
+RHEL-7.1 s390x/ppc64 boxes, and then taking the "select.o" file
+present at $builddir/misc/select.o.

+
+;; Fix '`catch syscall' doesn't work for parent after `fork' is called'
+;; (Philippe Waroquiers, RH BZ 1149205).
+;;=fedoratest
+
+URL: <https://sourceware.org/ml/gdb-patches/2013-05/msg00364.html>
+Message-ID: <1368136582.30058.7.camel@soleil>
+
+  From: Philippe Waroquiers <philippe dot waroquiers at skynet dot be>
+  To: gdb-patches at sourceware dot org
+  Subject: RFA: fix gdb_assert caused by 'catch signal ...' and fork
+  Date: Thu, 09 May 2013 23:56:22 +0200
+
+  The attached patch fixes a gdb_assert caused by the combination of catch
+  signal and fork:
+    break-catch-sig.c:152: internal-error: signal_catchpoint_remove_location: Assertion `signal_catch_counts[iter] > 0' failed.
+
+  The problem is that the signal_catch_counts is decremented by detach_breakpoints.
+  The fix consists in not detaching breakpoint locations of type bp_loc_other.
+  The patch introduces a new test.
+
+Comments by Sergio Durigan Junior:
+
+  I addded a specific testcase for this patch, which tests exactly the
+  issue that the customer is facing.  This patch does not solve the
+  whole problem of catching a syscall and forking (for more details,
+  see <https://sourceware.org/bugzilla/show_bug.cgi?id=13457>,
+  specifically comment #3), but it solves the issue reported by the
+  customer.
+
+  I also removed the original testcase of this patch, because it
+  relied on "catch signal", which is a command that is not implemented
+  in this version of GDB.

+Subject: gdb-rhbz1186476-internal-error-unqualified-name-re-set-test.patch
+
+;; Fix 'backport GDB 7.4 fix to RHEL 6.6 GDB' [Original Sourceware bug
+;; description: 'C++ (and objc): Internal error on unqualified name
+;; re-set', PR 11657] (RH BZ 1186476).
+;;=fedoratest
+
+Comments from Sergio Durigan Junior:
+
+  The "proper" fix for this whole problem would be to backport the
+  "ambiguous linespec" patch series.  However, it is really not
+  recommended to do that for RHEL GDB, because the patch series is too
+  big and could introduce unwanted regressions.  Instead, what we
+  chose to do was to replace the gdb_assert call by a warning (which
+  allows the user to continue the debugging session), and tell the
+  user that, although more than one location was found for his/her
+  breakpoint, only one will be used.
