The Piano application used to perform very poorly due to unnecessary
draw calls. This is solved with two optimziations:
1. Don't draw the widgets as often as possible. The widgets are instead
at least updated every 150ms, except for other events.
2. Don't re-draw the entire piano roll sheet. The piano roll background,
excluding in-motion objects (notes, the play cursor), is only re-drawn
when its "viewport" changes.
A minor drawback of this change is that notes will appear on top of the
pitch labels if placed at the left edge of the roll. This is IMO
acceptable or may be changed by moving the text to the "foreground".
Using rsync is significantly faster when we're using an existing
image because we only have to copy files which are new or have
been updated. This cuts down the image creation time to about
a second or two assuming an old image exists.
This adds support for re-using and re-sizing existing disk images.
Disk images are checked with e2fsck prior to re-use and a new disk
image is automatically created when that check fails.
The native C++ < and > operators won't handle this correctly, so the
result was different depending on the order of arguments. This is now
fixed by explicitly checking for positive and negative zero values.
Fixes#6589.
This adds support for detecting incorrect version numbers and links
in the ports list.
Also, unlike before it doesn't parse the package.sh script but executes
it instead which allows us to detect syntax errors.
The 'syscall-arguments' positional arg being required was
breaking the scenario where the user just passes the
'--list-syscalls' argument.
Instead, make the argument not required, and manually handle
the error path our selves.
Closes: #6574
This new check will ensure that all commit message lines are at most 72
characters long, as well as ensure the commit title conforms to the
"Category: Brief description of what's being changed" format.
Otherwise the notification would be deferred until the next read event,
which means the client will not get any events if the server initiates
the appdata transfers.
Previously this didn't work:
$ cd -- /usr
Invalid path '--'
This path fixes this issue and removes the unnecessary else
branch because we're already using realpath() later on to resolve
relative paths.
The hash for the master zip file changed again. Probably because
GitLab only caches those zip files for a bit and re-generates them
with slightly different zip headers after some time even though
the repository didn't change.
The new message for skipping builds makes it hard to
distinguish failed builds from builds that were just skipped
so change it back to the old one - but don't actually build
packages twice again.
GlyphBitmap width is currently limited to twiddling 32 bits so
abide by a 32x36 standard for now. Fixes incorrect line values and
ranges and removes unused RefPtr.
Problem:
- Some classes have `virtual` destructors despite not having any
virtual functions. This causes the classes to have a v-table and
perform extra jumps at destruction time when there is no need.
Solution:
- Remove `virtual` keyword from destructors where there are no other
virtual functions.
- Remove the destructor completely when the default destructor can be
used.
