The target board fission.exp requires the gold linker (because it supports
--gdb-index).
When running the target board on a system where the default linker is not
gold, most tests will fail to compile.
Fix this by adding "-fuse-ld=gold" ( supported in gcc since version 4.8).

When running fullpath-expand.exp with target_board=dwarf4-gdb-index, we run
into:
...
$ make check-gdb RUNTESTFLAGS="--target_board=dwarf4-gdb-index fullpath-expand.exp"
Running src/gdb/testsuite/gdb.base/fullpath-expand.exp ...
gdb compile failed, cc-with-tweaks.sh: unable to find usable gdb
=== gdb Summary ===
nr of untested testcases 1
...
The same happens with fullname.exp.
The dwarf4-gdb-index.exp board file includes cc-with-tweaks.exp, which uses
cc-with-tweaks.sh, which calls gdb-add-index.sh.
The gdb-add-index.sh script uses a gdb executable, defaulting to gdb:
...
GDB=${GDB:=gdb}
...
The cc-with-tweaks.sh script tries to ensure that the build gdb executable is
used by gdb-add-index.sh:
...
if [ -z "$GDB" ]
then
if [ -f ./gdb ]
then
GDB="./gdb -data-directory data-directory"
elif [ -f ../gdb ]
then
GDB="../gdb -data-directory ../data-directory"
elif [ -f ../../gdb ]
then
GDB="../../gdb -data-directory ../../data-directory"
else
echo "$myname: unable to find usable gdb" >&2
exit 1
fi
fi
...
So, if the current directory is build/gdb/testsuite, then a gdb executable
build/gdb/testsuite/../gdb will be used.
However, in the case of fullpath-expand.exp the test cd's into the sources:
...
set saved_pwd [pwd]
cd $srcdir
set err [gdb_compile "${subdir}/${srcfile} ${subdir}/${srcfile2}" $binfile \
executable {debug}]
cd $saved_pwd
...
and cc-with-tweaks.sh generates the "unable to find usable gdb" error.
The same error occurs if we use --target_board=cc-with-dwz instead (only in
this case we actually don't need gdb, we just need the GDB variable to be set
in cc-with-tweaks.sh, which arguably is a bug in cc-with-tweaks.sh).
Fix both errors in cc-with-tweaks.exp by generating a gdb script gdb.sh using
$GDB, $GDBFLAGS and $INTERNAL_GDBFLAGS and passing this script to
cc-with-tweaks.sh by setting env(GDB).
Tested on x86_64-linux for gdb.base.

We can use CC_WITH_TWEAKS_FLAGS when cd-ing into the gdb build subdir and

using CC_WITH_TWEAKS_FLAGS has no effect, because CC_WITH_TWEAKS_FLAGS is not

When testing using native-gdbserver and native-extended-gdbserver, the sysroot
is not set. This results in a warning from GDB and files are sent via the
remote protocol, which can be slow.
On Ubuntu 18.04 (unlike most distros) the debug versions of the standard
libraries are included by default in /usr/lib/debug/.
These file reads are causing a complete native-gdbserver run on the AArch64
buildbot slave to timeout after 2.5 hours. This is also causing the builds
to back up on the slave.
The solution is to ensure the sysroot is set to / for all local boards.
This drastically reduces the time of a test. For example, gdb.base/sigall.exp
drops from 23 seconds to 4 seconds.
A full native-gdbserver run on the AArch64 slave now takes 8 minutes.

This patch implements IPv6 support for both GDB and gdbserver. Based
on my research, it is the fourth attempt to do that since 2006. Since
I used ideas from all of the previous patches, I also added their
authors's names on the ChangeLogs as a way to recognize their
efforts. For reference sake, you can find the previous attempts at:
https://sourceware.org/ml/gdb-patches/2006-09/msg00192.html
https://sourceware.org/ml/gdb-patches/2014-02/msg00248.html
https://sourceware.org/ml/gdb-patches/2016-02/msg00226.html
The basic idea behind the patch is to start using the new
'getaddrinfo'/'getnameinfo' calls, which are responsible for
translating names and addresses in a protocol-independent way. This
means that if we ever have a new version of the IP protocol, we won't
need to change the code again (or, at least, won't have to change the
majority of the code).
The function 'getaddrinfo' returns a linked list of possible addresses
to connect to. Dealing with multiple addresses proved to be a hard
task with the current TCP auto-retry mechanism implemented on
ser-tcp:net_open. For example, when gdbserver listened only on an
IPv4 socket:
$ ./gdbserver --once 127.0.0.1:1234 ./a.out
and GDB was instructed to try to connect to both IPv6 and IPv4
sockets:
$ ./gdb -ex 'target extended-remote localhost:1234' ./a.out
the user would notice a somewhat big delay before GDB was able to
connect to the IPv4 socket. This happened because GDB was trying to
connect to the IPv6 socket first, and had to wait until the connection
timed out before it tried to connect to the IPv4 socket.
For that reason, I had to rewrite the main loop and implement a new
method for handling multiple connections. After some discussion,
Pedro and I agreed on the following algorithm:
1) For each entry returned by 'getaddrinfo', we try to open a socket
and connect to it.
2.a) If we have a successful 'connect', we just use that connection.
2.b) If we don't have a successfull 'connect', but if we've got a
ECONNREFUSED (meaning the the connection was refused), we keep track
of this fact by using a flag.
2.c) If we don't have a successfull 'connect', but if we've got a
EINPROGRESS (meaning that the connection is in progress), we perform
a 'select' call on the socket until we have a result (either a
successful connection, or an error on the socket).
3) If tcp_auto_retry is true, and we haven't gotten a successful
connection, and at least one of our attempts failed with
ECONNREFUSED, then we wait a little bit (i.e., call
'wait_for_connect'), check to see if there was a
timeout/interruption (in which case we bail out), and then go back
to (1).
After multiple tests, I was able to connect without delay on the
scenario described above, and was also able to connect in all other
types of scenarios.
I also implemented some hostname parsing functions (along with their
corresponding unit tests) which are used to help GDB and gdbserver to
parse hostname strings provided by the user. These new functions are
living inside common/netstuff.[ch]. I've had to do that since IPv6
introduces a new URL scheme, which defines that square brackets can be
used to enclose the host part and differentiate it from the
port (e.g., "[::1]:1234" means "host ::1, port 1234"). I spent some
time thinking about a reasonable way to interpret what the user wants,
and I came up with the following:
- If the user has provided a prefix that doesn't specify the protocol
version (i.e., "tcp:" or "udp:"), or if the user has not provided
any prefix, don't make any assumptions (i.e., assume AF_UNSPEC when
dealing with 'getaddrinfo') *unless* the host starts with "[" (in
which case, assume it's an IPv6 host).
- If the user has provided a prefix that does specify the protocol
version (i.e., "tcp4:", "tcp6:", "udp4:" or "udp6:"), then respect
that.
This method doesn't follow strictly what RFC 2732 proposes (that
literal IPv6 addresses should be provided enclosed in "[" and "]")
because IPv6 addresses still can be provided without square brackets
in our case, but since we have prefixes to specify protocol versions I
think this is not an issue.
Another thing worth mentioning is the new 'GDB_TEST_SOCKETHOST'
testcase parameter, which makes it possible to specify the
hostname (without the port) to be used when testing GDB and
gdbserver. For example, to run IPv6 tests:
$ make check-gdb RUNTESTFLAGS='GDB_TEST_SOCKETHOST=tcp6:[::1]'
Or, to run IPv4 tests:
$ make check-gdb RUNTESTFLAGS='GDB_TEST_SOCKETHOST=tcp4:127.0.0.1'
This required a few changes on the gdbserver-base.exp, and also a
minimal adjustment on gdb.server/run-without-local-binary.exp.
Finally, I've implemented a new testcase,
gdb.server/server-connect.exp, which is supposed to run on the native
host and perform various "smoke tests" using different connection
methods.
This patch has been regression-tested on BuildBot and locally, and
also built using a x86_64-w64-mingw32 GCC, and no problems were found.

As described here
https://sourceware.org/bugzilla/show_bug.cgi?id=22841
there seems to be situations where the remote-stdio-gdbserver board
fails to delete the uploaded binary file. Passing "target" fixes the
issue for Christian who reported the bug.
I did not experience this problem, but passing "target" to remote_exec
still works for me, so I'm fine with changing it.

Before patch
Make native gdbserver boards no longer be "remote" (in DejaGnu terms)
739b3f1d8ff7072dcc66240c25b026c6433bda1a
the local gdbserver boards (except native-extended-gdbserver...) were
considered as remote by DejaGNU. To avoid DejaGNU trying to use ssh/scp
to download the files to the target (which is actually local), the
gdbserver-base.exp file defined some _download, _upload and _file board
operations to override the default behavior, and instead just use local
operations.
The same patch also changed remote-stdio-gdbserver.exp to make it
inherit from gdbserver-base.exp. Since then, this board (which is
actually remote) uses the overrides with local file operations. As a
result, files are never actually copied to the target.
I think we can simply remove the overrides from gdbserver-base.exp.
Because all boards should be properly considered local or remote by
DejaGNU, it should by default use the right method for transferring
files.

I've noticed now that due to a last-minute change, commit 739b3f1d8ff7
("Make native gdbserver boards no longer be "remote" (in DejaGnu
terms)") managed to miss loading "local-board" in the
native-stdio-gdbserver board...

* boards/native-stdio-gdbserver.exp: Load "local-board".
|
|
This commit finally clears the "isremote" flag in the native-gdbserver
and native-stdio-gdbserver boards. The goal is to make all "native"
boards be considered not remote in DejaGnu terms, like the
native-extended-gdbserver board is too.
DejaGnu automatically considers boards remote if their names don't
match the local hostname. That means that native-gdbserver and
native-extended-gdbserver are considered remote by default by DejaGnu,
even though they run locally. native-extended-gdbserver, however,
overrides its isremote flag to force it to be not remote. So we are
in that weird state where native-gdbserver is considered remote, and
native-extended-gdbserver is considered not remote.
A recent set of commits fixed all the problems (and some more) exposed
by testing with --target_board=native-gdbserver and
--target_board=native-stdio-gdbserver with isremote forced off on
x86-64 GNU/Linux. I believe we're good to go now.
The native-stdio-gdbserver.exp/remote-stdio-gdbserver.exp boards
required deep non-obvious modifications unfortunately... The problem
is that if a board is not remote, then DejaGnu doesn't call
${board}_spawn / ${board}_exec at all, and the
native-stdio-gdbserver.exp board relies on those procedures being
called. To fix that, this commit redesigns how the stdio boards hook
into the testing framework to spawn gdbserver. IMO, this is a good
change anyway, because the way its done currently is a bit of a hack,
and the result turns out to be simpler, even. With this commit, they
now no longer load the "gdbserver" generic config, and hook at the
mi_gdb_target_load/gdb_reload level instead, making them more like
traditional board files.
To share code between native-stdio-gdbserver.exp and
remote-stdio-gdbserver.exp, a new shared stdio-gdbserver-base.exp file
is created.
Instead of having each native board clear isremote manually, boards
source the new "local-board.exp" file.
This also adds a new section to testsuite/README file discussing
local/remote/native, so that we can easily refer to it.

This commit makes --target_board=native-gdbserver (and in principle
all other is_remote boards) pass all the same gdb.base/scope.exp tests
as native testing.
I first wrote the gdb.base/scope.exp change described in the ChangeLog
below and in the new comments in the patch, knowing that gdb_file_cmd
was the right thing to use here.
However, that revealed that the native-extended-gdbserver board should
be overriding gdb_file_cmd+gdb_reload instead of gdb_load, as is
hinted at by the comments on top of the default implementations in
testsuite/lib/gdb.exp, because otherwise a gdb_run_cmd after
gdb_file_cmd misses setting "set remote exec-file". However, if we do
that and remove gdb_load, then we regress gdb.base/dbx.exp, so for now
keep the gdb_load override as well.

gdbserver-base.exp is used as the base for both native-gdbserver.exp and
native-extended-gdbserver.exp. (Despite its name, it should really be
considered as a "local-gdbserver-base", as it's not really appropriate to
implement a remote gdbserver board.)
Currently, the _download procedure is implemented as a no-op (it returns
the source file path). Because of the SONAME change, The fast
tracepoint tests now require the executable and the IPA
(libinproctrace.so) to be located in the same directory (see [1]). When
using the native-gdbserver board, because _download returns the original
file path, the executable does not end up in the same directory as the
library, and it fails to execute.
In more general terms, with the recent changes, the testsuite now
assumes that when it does
${board}_download <source path 1> <destination path 1>
${board}_download <source path 2> <destination path 2>
where the destination paths are relative (generally just the file name),
both files will end up in the same base directory. That assumption does
not hold for the current implementation in gdbserver-base.exp.
The proper fix would be to make native-gdbserver non-remote, so that
gdb_remote_download would not call DejaGnu's remote_download (see [2]).
We could then get rid of ${board}_download in gdbserver-base.exp.
However, that will likely take some time to complete. In the mean time,
in order to make the fast tracepoint tests pass, we can simply copy the
file to the standard output directory. Basically, it just mimics what
gdb_remote_download would do if the board wasn't flagged as remote.
Note that I missed these failures originally because I had a
libinproctrace.so in /usr/local/lib. So, even though libinproctrace.so
wasn't copied to the test output directory, it did find the one in

as it could easily happen again...
Regtested with unix, native-gdbserver and native-extended-gdbserver, and
didn't see anything notable, except the ftrace tests now passing for
native-gdbserver.

inferior output with "-i $inferior_spawn_id", we can remove this now,
and thus enable those tests against gdbserver.

These tests do something like this:
#0 - start gdb/gdbserver normally
#1 - setup some things in the debug session
#2 - disconnect from gdbserver
#3 - restart gdb
#4 - reconnect to gdbserver
The problem is that the native-extended-gdbserver board always spawns
a new gdbserver instance in #3 (and has gdb connect to that). So when
the test gets to #4, it connects to that new instance instead of the
old one:
(gdb) spawn ../gdbserver/gdbserver --multi :2354
Listening on port 2354
target extended-remote localhost:2354

Running the testsuite with the native-extended-gdbserver.exp board and
passing a variant spec, like
make check RUNTESTFLAGS="--target_board=native-extended-gdbserver/-m32"
results in dejagnu trying to open a rsh connection to
"native-extended-gdbserver", which of course is wrong. The point of
this board is running things locally.
The issue is that the native-extended-gdbserver board does not clear
the "isremote" flag properly.

In the recent review to my patch about copying files to remote host,
we find that we need a board file which is more closely mapped real
remote host testing to improve coverage. With the board file
local-remote-host-native.exp, DejaGNU copies files to
$build/gdb/testsuite/remote-host to emulate the effect of remote host.
Is it OK?

Sometimes it's useful to be able to disable the automatic connection
to the native target. E.g., sometimes GDB disconnects from the
extended-remote target I was debugging, without me noticing it, and
then I do "run". That starts the program locally, and only after a
little head scratch session do I figure out the program is running
locally instead of remotely as intended. Same thing with "attach",
"info os", etc.
With the patch, we now can have this instead:
(gdb) set auto-connect-native-target off
(gdb) target extended-remote :9999
...
*gdb disconnects*
(gdb) run
Don't know how to run. Try "help target".
To still be able to connect to the native target with
auto-connect-native-target set to off, I've made "target native" work
instead of erroring out as today.
Before:
(gdb) target native
Use the "run" command to start a native process.
After:
(gdb) target native
Done. Use the "run" command to start a process.
(gdb) maint print target-stack
The current target stack is:
- native (Native process)
- exec (Local exec file)
- None (None)
(gdb) run
Starting program: ./a.out
...
I've also wanted this for the testsuite, when running against the
native-extended-gdbserver.exp board (runs against gdbserver in
extended-remote mode). With a non-native-target board, it's always a
bug to launch a program with the native target. Turns out we still
have one such case this patch catches:
(gdb) break main
Breakpoint 1 at 0x4009e5: file ../../../src/gdb/testsuite/gdb.base/coremaker.c, line 138.
(gdb) run
Don't know how to run. Try "help target".
(gdb) FAIL: gdb.base/corefile.exp: run: with core
On the patch itself, probably the least obvious bit is the need to go
through all targets, and move the unpush_target call to after the
generic_mourn_inferior call instead of before. This is what
inf-ptrace.c does too, ever since multi-process support was added.
The reason inf-ptrace.c does things in that order is that in the
current multi-process/single-target model, we shouldn't unpush the
target if there are still other live inferiors being debugged. The
check for that is "have_inferiors ()" (a misnomer nowadays...), which
does:
have_inferiors (void)
{
for (inf = inferior_list; inf; inf = inf->next)
if (inf->pid != 0)
return 1;
It's generic_mourn_inferior that ends up clearing inf->pid, so we need
to call it before the have_inferiors check. To make all native
targets behave the same WRT to explicit "target native", I've added an
inf_child_maybe_unpush_target function that targets call instead of
calling unpush_target directly, and as that includes the
have_inferiors check, I needed to adjust the targets.
Tested on x86_64 Fedora 20, native, and also with the
extended-gdbserver board.
Confirmed a cross build of djgpp gdb still builds.
Smoke tested a cross build of Windows gdb under Wine.
Untested otherwise.

After I run test like this,
$ make check RUNTESTFLAGS='--host_board=local-remote-host dw2-basic.exp'
gdb.dwarf2/file1.txt in source tree was removed. In some gdb.dwarf2/*.exp,
file1.txt is copied to host and then removed at the end. However, in
local-remote-host-notty.exp, ${board}_download doesn't copy the file but
return the absolute path of the src file. 'remote_file host delete' at
the end will remove the file in source tree.
This patch is to overwrite ${board}_file, and specially make "delete"
option do nothing. This approach is used in gdbserver-base.exp and
remote-stdio-gdbserver.exp too.

In a test I was writting, I needed a procedure that would connect to
the target, and do "load", or equivalent.
Years ago, boards would override gdb_load to implement that. Then
gdb_reload was added, and gdb_load was relaxed to allow boards avoid
the spawing and connecting to the target. This sped up gdbserver
testing. See
https://www.sourceware.org/ml/gdb-patches/2007-02/msg00318.html.
To actually spawn the target and load the executable on the target
side, gdb_reload was born:
# gdb_reload -- load a file into the target. Called before "running",
# either the first time or after already starting the program once,
# for remote targets. Most files that override gdb_load should now
# override this instead.
proc gdb_reload { } {
# For the benefit of existing configurations, default to gdb_load.
# Specifying no file defaults to the executable currently being
# debugged.
return [gdb_load ""]
}
Note the comment about specifying no file. Indeed looking at
config/sid.exp, or config/monitor.exp, we see examples of that.
However, the default gdb_load itself doesn't handle the case of no
file specified. When passed no file, it just calls gdb_file_cmd with
no file either, which ends up invocing the "file" command with no
argument, which means unloading the file and its symbols... That
means calling gdb_reload when testing against native targets is
broken. We don't see that today because the only call to gdb_reload
that exists today is guarded by target_info exists
gdb,do_reload_on_run.
The native-extended-gdbserver.exp board is likewise broken here. When
[gdb_load ""] is called, the board sets the remote exec-file to "" ...

extended-remote gdbserver.

That "break exit" + "continue" comes from:

> #
The native-gdbserver.exp board, used to test against gdbserver in
"target remote" mode, triggers that case ($use_gdb_stub is true). So
gdb_continue_to_end doesn't work for catch-syscall.exp as here we
catch the exit_group and continue from that, expecting to see a real
program exit. I was about to post a patch that changes
catch-syscall.exp to call a new function that just always does what
gdb_continue_to_end does in the !$use_gdb_stub case. But, since
GDBserver doesn't really need this, in the end I thought it better to
teach the testsuite that there are stubs that know how to report
program exits, by adding a new "exit_is_reliable" board variable that
then gdb_continue_to_end checks.

In extended-remote, when GDB connects the target, but target is not
running, the TSVs are not uploaded. When GDB attaches to a process,
the TSVs are not uploaded either. However, GDBserver has some

A few months ago semicolons after "return" were removed throughout the
testsuite. However, as I pointed out in review, they're unnecessary
not just after "return", but pretty much after any tcl command. ';'
is the command separator, and you only need it if there's another
command on the same line afterwards.
This patch was written by running:
$ find . -name "*.exp" | xargs grep -l ";\s*$" | xargs sed -i 's/\([^#][^\s*;]*\)\s*;\s*$/\1/'
and then undoing changes to comments, and lib/future.exp.
