With this, all the files are organised into Components,
each of which points to a Directory defined in the StandardDirectory element.
This simplifies the Feature element considerable as only thing it needs to
include everything in the built msi is a reference to `ApplicationComponents`
- The Keywords and Description items move under a new SummaryInformation element.
- Shuffle things around so that elements previously under the product element are now under the Package element.
- Rename SummaryCodepage in SummaryInformation to Codepage and remove a duplicate Manufacturer item.
- Remove InstallerVersion and let WiX set it to default value. (500 a.k.a Windows 7)
Do not close stderr as part of the Qubes termination logic, since we
need to read the debug logs. This shouldn't affect typical termination
scenarios, since we expect our disposable qube to be either busy reading
from stdin, or writing to stdout. If this is not the case, then
forcefully killing the `qrexec-client-vm` process should unblock the
qube.
Add a doc that contains an MP4 video in it, which has an audio and video
stream. This type of document could not be converted with the latest
Dangerzone releases, because PyMuPDF threw this error in the container's
stdout:
MuPDF error: unsupported error: cannot create appearance stream for
Screen annotations
This error message was treated literally by our client code, which
parsed the first few bytes in order to find out the page height/width.
This resulted to a misleading Dangerzone error, e.g.:
A page exceeded the maximum height
This issue started occurring since 0.6.0, which added streaming support,
and was fixed by commit 3f86e7b465. That
fix was not accompanied by a test document that would ensure we would
not have this regression from now on, so we add it in this
commit.

Remove some macOS entitlements that are not necessary for the current
iteration of Dangerzone. Those are the ability to run as a hypervisor,
and the ability to accept network connections. They are a relic from
when we were experimenting with VMs, instead of relying on Docker
Desktop.
Make the Dummy isolation provider follow the rest of the isolation
providers and perform the second part of the conversion on the host. The
first part of the conversion is just a dummy script that reads a file
from stdin and prints pixels to stdout.
Extend the base isolation provider to immediately convert each page to
a PDF, and optionally use OCR. In contract with the way we did things
previously, there are no more two separate stages (document to pixels,
pixels to PDF). We now handle each page individually, for two main
reasons:
1. We don't want to buffer pixel data, either on disk or in memory,
since they take a lot of space, and can potentially leave traces.
2. We can perform these operations in parallel, saving time. This is
more evident when OCR is not used, where the time to convert a page
to pixels, and then back to a PDF are comparable.
The PyMuPDF package was previously mainly used within the Dangerzone
container, as well as on Qubes. With on-host conversion, PyMuPDF will be
used in all supported platforms by default. For this reason, we can
promote it to a main dependency.
Add a new way to detect where the Tesseract data are stored in a user's
system. On Linux, the Tesseract data should be installed via the package
manager. On macOS and Windows, they should be bundled with the
Dangerzone application.
There is also the exception of running Dangerzone locally, where even
on Linux, we should get the Tesseract data from the Dangerzone share/
folder.
Add a Python script that can run in all supported platforms, and can
download and extract the Tesseract language data from GitHub, while
also:
1. Checking that the expected hash matches.
2. Informing the user if the language data have already been downloaded.
3. Extracting only the subset of language data that Dangerzone needs
GitHub actions somehow managed to downgrade our runners from Ubuntu
24.04 to Ubuntu 22.04, even though we use `ubuntu-latest`. Make the
Ubuntu 24.04 requirement more explicit, until GitHub migrates fully to
this version for the `ubuntu-latest` tag.
