Create gdb.debug, gdb.cmd and gdb.in files when running the testsuite
Extended version of a previous series.
This series is intended to help with reproducing tests and extracting debug
information from them.
Firstly, this adds the ability to capture GDB debug when running the testsuite.
For example:
make check GDB_DEBUG="infrun,remote,serial,jit,frame"
Debug output is saved to gdb.debug in the test directory, along with all of
the gdb output for the test.
Secondly, whenever a test is run, gdb.in and gdb.cmd files will be created
containing the input passed to gdb and the command line used to launch gdb.
This allows a user to quickly rerun a test outside of dejagnu - a script is
added to automate that process too.
Thirdly, GDBSERVER_DEBUG is extended to support the saving of gdbreply output
to a gdbserver.replay file.
I'll do a follow on patch for the NEWS file and look at updating the wiki with
examples.
Alan Hayward (9):
Change file close behavior for tee_file
Add debug redirect option
testsuite: Add option to capture GDB debug
testsuite: Disable some tests when logging
testsuite: Record all gdb input to gdb.in
testsuite: Create .cmd files for gdb and gdbserver
testsuite: Add replay logging to GDBSERVER_DEBUG
testsuite: Add script to quickly re-run tests
testsuite: Remove TRANSCRIPT support

Add both board option and environment variable which enables gdb
debug via a comma separated list and sends it to the file gdb.debug,
located in the output directory for the current test. Document this.
Add support for the environment variable in the Makefile.
The testsuite can be run with gdb debug enabled in the following way:
make check GDB_DEBUG="infrun,target,remote"
A Test with multiple invocations of GDB will all append debug to the
same log file.

* Makefile.in: Pass through GDB_DEBUG.
* README (Testsuite Parameters): Add GDB_DEBUG.
(gdb,debug): Add board setting.
* lib/gdb.exp (default_gdb_start): Start debugging.
(gdb_debug_enabled): New procedure.
(gdb_debug_init): Likewise.

Instead of using two bools to decide if the files should close when tee_file
is closed, make file one stay open and file two close. This simplifies the
use cases for it.
Inline the make_logging_output into the calling functions (the logic here
looks ugly in order to simplify a later change).
Expand ui-redirect.exp to cover the changes, similar to mi-logging.exp.

When spawning gdb or gdbserver create a .cmd file in the test output
directory containing the full command line, ensuring the current gdb
instance is appened to the files so that they can be quickly matched
to the corresponding gdb.in file.

Add "replay" to the list of GDBSERVER_DEBUG options. This will
cause a gdbserver.replay file to be written to the test output
directory.
At the same time switch this to a comma separated list in order
to easily handle all possible options.
The replay log is created by GDB, but has been added to
GDBSERVER_DEBUG as it is only required for gdbserver tests. To
enable it, the gdb_debug_init is overridden to allow the additional
checking, before calling the original function.

Using the .cmd and .in files created by a test it is fairly simple
to manually re-run a test. For gdbserver tests, the .replay log
can also be used.
Document the process required to do this.
In addition create a script to automate the process.

+Re-running Tests Outside The Testsuite
+**************************************
+
+When running a test, the arguments used to run GDB are saved to gdb.cmd
+and any commands sent to GDB are saved to gdb.in. As well as being a
+reference of the commands run, they can be used to manually re-run a test
+by giving the .in file as a batch file to a GDB launched with the arguments
+in the .cmd file. For many tests you can use just the .in file:
+ $ gdb -x gdb.in
+
+Tests that run GDB multiple times will append .1, .2, .3 etc to the end
+of each .cmd and .in file.
+
+For tests requiring gdbserver, this can by executing the contents of
+gdbserver.cmd. Alternatively, the gdbserver.replay file (created when
+running the test with GDBSERVER_DEBUG="replay") can be used with the
+gdbreplay test.
+
+This process can be automated with the "replaytest" script.
+For example:
+ $ replaytest gdb testsuite/outputs/gdb.base/store
+For more details see the documentation in the script.

Fix up all failures encountered when running the testsuite with
GDB_DEBUG="infrun".
Some tests rely on enabling debugging for various components. With
debugging on, this will be lost to the debug file.
Disable separate tty for mi tests when debugging. This currently
does not work.
disasm.c should send errors to the stderr instead of the logfile.
Note that enabling debug for other components might still cause
additional errors above what has been fixed here.

From: Alan Hayward @ 2019-05-14 15:13 UTC (permalink / raw)
To: gdb-patches; +Cc: nd, Alan Hayward
When debugging testsuite failures, it can be awkward parsing gdb.log to
obtain all the commands run in order to manually re-run the test.
This patch adds the functionality to save all gdb commands to the file gdb.in
when the testsuite is run. The file is saved in the directory for the test and
if gdb is restarted then .1, .2, .3 etc is added to the filename.
Once a test has been run, the .in file can be used to re-run the test in the
following way:
gdb -x outputs/gdb.store/gdb.in outputs/gdb.store/store
The code works by intercepting send_gdb. I've added a TYPE to ensure that any
commands that would destroy the playback are kept from the log (for example the
Y from an answer to a y/n question).
Adds library function standard_output_file_with_gdb_instance to open a file
postfixed with count of the gdb instance. Ensure this count is reset when a new
.exp script is run.
I've re-run a random selection of .in files to check they do not error. Logs with
commands such as "attach <pid>" will not directly work when re-run.

Currently, when logging is enabled, output will be sent to both a
logfile and standard terminal output. The redirect option sends output
only to the logfile. This includes all debug output.
Add the option to redirect debug output seperately to normal
output, using the cli command:
set logging debugredirect on
By setting this and enabling logging, all output and debug will
be sent to the logfile. The user will still see all output but
no debug output.
This causes a change in behaviour for anyone currently using
logging redirect, as now only output will be redirected. Users
will have to issue the additional command above to also redirect
debug.
Expand ui-redirect.exp cover the changes.
gdb/ChangeLog:
2019-05-14 Alan Hayward <alan.hayward@arm.com>
* cli/cli-interp.c (struct saved_output_files): Add saved entry.
(cli_interp_base::set_logging): Check debug_redirect.
* cli/cli-interp.h (set_logging): Add debug_redirect parameter.
* cli/cli-logging.c (debug_redirect): Add static variable.
(pop_output_files): Add default param.
(handle_redirections): Print debug setting.
(show_logging_command): Likewise.
(_initialize_cli_logging): Add debugredirect command.
* interps.c (current_interp_set_logging): Add debug_redirect
parameter.

Thank you. This seems very handy.

Does this placement work even if a single runtest runs multiple .exp

Normally the GNU style reserves upper-case in situations like this to
refer to the value of a variable. For a string I would just use quotes,
like:
# "standard": Default. ...

Typo in the commit message, should be "appended", but otherwise looks
good. Thanks.

It's best to land the documentation patch with the code change -- not to
wait until later. The reason for this is that sometimes other events
intervene, and then we're left with an undocumented feature. It's
similar to the situation with writing tests.
In this case, no need to back things out. Just write the doc patch; and
in the future please do it as a unit.
thanks,
Tom
