This will reduce the size of crash dumps, especially if
there are large binaries.
|
|
Correct several problems parsing sub binaries. A sub binary
would often be replaced with '#CDVNonexistingBinary'.
When parsing a sub binary, we must scan ahead to find the
definition of the refc or heap binary being referenced.
|
|
This test failed every now and then since the selected max size could
be greater than the actual size of the dump - so the dump was not
truncated. This is now corrected.
|
|
|
|
If the version of the given crash dump is newer than what
crashdump_viewer is prepared to read, then crashdump_viewer will
display an info dialog and then terminate. This is to allow major
updates of the format of crash dumps.
|
|
|
|
When a literal was used from several processes, the literal would
be dumped in only one of the processes. The other processes
that referenced the literals would have incomplete heap data.
|
|
Maps would be dumped as the atom 'undefined', which is
not very informative.

Earlier, crashdump_viewer stored an index of all binaries in a gb_tree
on startup. The binary index was also stored in the
cdv_dump_index_table along with all other "=xxx" tags from the
dump. The difference between the indices was that the ets table
contained the addresses of the binaries as strings (the hex address
found after the "=binary:" tag) and in the gb_tree this hex address
was instead converted to its integer value. The index in the ets table
was only used once - when creating the gb_tree. The gb_tree was used
for all later looups (to map integer address to file position).
This commit replaces the two storages with one new ets table,
cdv_binary_index_table, using the integer value of the hex address as
key, and the position in the crashdump file as value. In the case of
many binaries, this makes the start of crashdump viewer faster (only
one place to write), and the data usage smaller (hex address strings
are no longer stored). And it avoids the gc of the gb_tree.

This is a bug fix: the end of the 'Last calls' section is meant to be
an empty line, but in some situations this is not the case. This could
cause the complete dump to be read and stored as 'Last calls', causing
very unexpected behavior in the crashdump viewer.
This commit adds a check for ": ", which indicates that a new heading
has occured and thus the 'Last calls' section is completly read.

Compatibility two releases back are tested, which implies R18.

Fix observer application crash
When clicking an HTML-link to a port before the port tab has been opened for the first time, observer would crash since port info is not initiated. This is now corrected.
Also, when clicking on an HTML link to a port, and the port does not exist,
then pop up an info dialog saying "No such port".

If a crashdump is truncated due to size limit reached, a new 'abort'
tag with reason is added at the end of the crashdump. This reason is
now displayed along with the truncated-warning.

After bumping to Erlang/OTP 19, R16 dumps can no longer be
created. Now we test dumps from OTP 17 and 18.

This was earlier filename:dirname(code:which(test_server)). On
Microsoft Windows, this pointed to a directory under c:/Program Files,
and in later versions this directory is no longer writable. The
framework (common_test) log dir is now used instead.
|
|
Since no test suites includede test_server.hrl, there is no need
to have test_server in the include path or code path.
|
|
As a first step to removing the test_server application as
as its own separate application, change the inclusion of
test_server.hrl to an inclusion of ct.hrl and remove the
inclusion of test_server_line.hrl.

Add a new menu to toggle log view.
Disabled by default.
Disabled if rb_server already started on observed node,
in order not to interfere with somebody else.
If enabled, add a tab in process view where log entries
related to pid process are shown.
Need an observed node with at least a version R16B2,
due to the use of newly capability to rb to write into
a file descriptor (on the observing node).

crashdump_viewer would crash if the owner of a timer was specified as
the process' regisered name. This has been corrected.

After bumping to Erlang/OTP 18, R15 dumps can no longer be
created. Now we test dumps from R16B and 17.

Ensure that the server exists on close, even though linked to the test process

* siri/master-cuddle-with-tests:
Stop nodes after test cases in release_handler_SUITE
Add debug printouts in release_handler_SUITE:upgrade_gg

* dgud/observer/test:
observer: Add simple test and add debug hooks in app
|
|
Add hooks in observer so that we can do some basic testing on it
|
|
Instead of setting a timer and expecting all processes to be
terminated, set a monitor and wait for them to terminate.
|
|
A node to which we have references to multiple instances (creations)
will have an information line in the crashdump like this:
Creation: 1 2 ...
This would earlier crash because crashdump_viewer would try to do
list_to_integer on the value after "Creation: ". This is now
corrected.
This correction also helps the case when the emulator is debug
compiled, since the line could then be
Creation: 1 (refc=1)

Add the mentioned test suites for *all* library and touched
non-library applications.

Should not call showModal on a wxProgressdialog it is already display
