a660077c97 PlaybackBuffer: extend API to include write_ptr()
It's just useful
2020-05-13 23:55:02 -06:00
98d56d6b21 Add API to PlaybackBuffer to compute amount of data that can overwritten
The distance is between a given offset in the buffer (probably a
read position at some point in time) and the write ptr. Any data after
the write ptr is "old" and not readable, and thus not worth overwriting
since we would not read it anyway.

Fix parsing XML with blanks from memory
This is needed when the butler thread loads a plugin with
MIDNAM. xmlKeepBlanksDefault() setting is per thread.

Prevent huge stack allocations for MIDNAM files
xmlParseMemory() uses a c-pointer char*.
Previously MIDNAM data on the heap were wrapped inside
a std::string only to be later accessed via c_str().

c74cc2675e Extend FileArchive to import archive entries individually
This is needed primarily for a workaround for #7971. When importing a template
that has been exported on Ardour5 on MacOS we need to fix the paths of the
archive entries.

Later we can use this functionality also to handle imported templates if
templates with the same name already exist.

This commit only adds methods and members to FileArchive, it does not modify
anything to make regressions unlikely. This, however, leads to some duplicated
code. Eventually we should consolidate this a bit.

4dd3d4effe Some initial changes (currently for libpbd only) to help a new contributer who's trying to build with MSVC2017
These changes compile okay for me (using VS2019) although they wouldn't link to my older-built libraries. Hopefully he'll be okay if he builds everything with the same compiler.

Fix MacOS 10.11 (clang-8.0.0) builds
gcc, and recent clang-10 can construct new objects
using references as arguments.

However clang-8 (and MSVC?) do not:
   "error: no matching function for call to 'operator new'"

The compiler apparently does not expand the template
  class A  <-> `A*`  vs. `A const&`
for different cases.

Add a STL Allocator using the stack (for rt safety)
This is a dumb stack allocator using LIFO allocation/free, with
a fallback to new/delete. This works well for small STL containers
in particular std::vector, but it's also suitable for std::map<>,
in particular copy constructing small POD maps (plugin pin mappings).

Eventually this could be combined with TLSF for a flexible
memory arena management. This is however not currently needed
for any the planned use-cases.

This code is ANSI C++98 compatible, and yet also works with
modern C++11, C++14

Fix some recursive undo removal
~StatefulDiffCommand() may trigger UndoTransaction::command_death()
which may delete the StatefulDiffCommand() that's just being destroyed.

This depends on the signal-connection order, which is undefined.
In any case when a shared_ptr<> object is being destroyed it means
that all references to it are already gone. There's no need to
emit drop_references from the d'tor.

Fix double free of undo commands (amend 9e6435ff14)
This fixes a case when deleting a plugin, deletes all automation
undo/redo events:
  <UndoTransaction name="add automation event">
    <MementoCommand type-name="ARDOUR::AutomationList">
   ...


`delete this;` calls the d'tor which emits drop_references(),
that leads to UndoTransaction::command_death() destroying the
object, whichh causes a double free.

Fix mem-leak, Playlist/Region SessionHandleRef
When a playlist is deleted and drops_references(), any
undo/redo StatefulDiffCommand referncing playlist invoke
Destructible::drop_references() of the Command.

This leads to command_death(). As opposed to UndoTransaction::clear()
the StatefulDiffCommand was not destroyed.

In case of playlists StatefulDiffCommand::_changes contains
PBD::SequenceProperty<std::list<boost::shared_ptr<Region> > >
and shared pointer reference of the playlist regions were kept
indefinitely.

This fixes the following scenario:
New session, import an file, delete the created track,
clean up unused sources (delete unused playlists)[, quit].

A reference to the imported region was kept, because of the
playlist's undo command (insert region). Yet the source file
was deleted.


PS. Most playlist changes are accompanied by GUI zoom/selection
MementoCommands. Those are currently never directly dropped.
command_death() leaves those in place.

Fix Inline-control visibility state
This fixes an issue when copy/pasting plugins or aux-sends from
one track to another. After copying the processor, the state
is copied, however the Controllable state did save
the InlineControl flag, so this as lost.

get/set value are significant.

5ff8e260ff remove unnecessary call to xmlKeepBlanksDefault() 2020-01-05 17:58:54 -07:00
df3a4ed9c6 move call to xmlKeepBlanksDefault(0) to before the creation of an XML parser context
the value is used by the parser context; the old code called it only after the *first* parser context
was created. therefore the first XMLTree::read() call has its behavior determined by libxml2's default
for this value, rather than by our explicit choice (do not treat whitespace as a note). All subequent
read() calls will use our value.

This variable inside libxml2 is actually per-thread, which just increases the stakes for calling
xmlKeepBlanksDefault() at the right time
