5 years agoSwitch segment storage from single vector to vector of arrays
Soeren Apel [Wed, 8 Feb 2017 17:30:41 +0000 (18:30 +0100)]
Switch segment storage from single vector to vector of arrays

Previously, PV would run out of storage space for the data
segments because data was stored in a vector. As a vector allows
contiguous access to the underlying data (much like an array),
it needs a contiguous section of memory. With incoming data and
constant resizing of the vector, the OS at some point can no
longer supply such a section of memory, causing PV to abort

This change fixes this by using several chunks that are never
grown in size. Instead, new chunks are allocated and added to
the vector as needed. This way, the OS will be able to provide
memory until it runs out of system memory.

the link libraries list (for both PulseView and the unit tests).

Fix #805 by resetting selected device on failure

It can happen that devices can be selected but not used
(permissions problems, connection issues, driver issues, etc.),
so in those cases we want to fail gracefully instead of

consistent with the internal state.

cmake: add check for explicit linking against libatomic

To use atomics functions, some toolchains requires to explicitly add
-latomic to the linker flags (because they are not provided by libc,
but libatomic).

This change adds a helper function trying to build/link a test program
using atomics, then calls it to:
* first check if atomics are directly available in the libc;
* if not and libatomic has been found, then run the same test with
  "-latomic" added to the linker flags.
The pulseview link library list is updated according to the results of
these tests.

This issue was triggered by the Buildroot farms:

1- CMAKE_REQUIRED_* variables are only used in check functions. They
   are not automatically forwarded to/handled by the target commands
   (such as target_link_library), because the check functions are
   implemented as macro in CMake code, whereas many target commands
   are native.
2- Because of note #1, CMAKE_REQUIRED_LIBRARIES (or its value) must be
   explicitly passed to the target_link_library command when this is
3- In this implementation, LIBATOMIC_LIBRARY is only set when it is
   needed; so, unconditionally appending it to PULSEVIEW_LINK_LIBS
   will produce the expected behavior.

This fixes bug #810.

Session: Keep track of signal data locally

Currently, the Session class doesn't hold pointers to the signal

of signals it has. As the Session is providing the model in the

InputFile: Use new reset() function to allow re-reading file

Commit 519d0ccbe67d005a9c442795ce3b8255e78ca46d tried to solve
the problem of being unable to re-read an opened file by clicking
the "run" button. However, the solution is insufficient.
PV expects the session device to be updated after the open()
call. If it is not, the device settings popup will show the
settings of the previously used device.

This patch fixes this and also makes use of the new reset()
method to allow re-reading of the file contents. The method
is necessary because otherwise we have to destroy the input
module and create a new instance. This however also means
setting a new session device, which is highly undesirable.
So reset() it is.
