We'd unconditionally get the int from a Variant<int, float> here,
but PDFs often have a float for defaultWidthX and nominalWidthX.
Fixes crash opening Bakke2010a.pdf from pdffiles (but while the
file loads ok, it looks completely busted).
We already set these variables and call `_init` in the dynamic linker.
As we don't care about static binaries, remove these assignments and the
call to `_init` from `_entry`.
The function referenced by DT_INIT is also not necessarily called
`_init`, so directly calling `_init` is not really correct.
`s_global_initializers_ran` and `__stack_chk_guard` are unused, so
remove them.
We currently don't call any DT_FINI_ARRAY functions, so change that.
The call to `_fini` in `exit` is unnecessary, as we now call the
function referenced by DT_FINI in `__call_fini_functions`.
We currently store a StringView into the DeprecatedString provided to
SVGUseElement::attribute_changed. This is a temporary string created by
String::to_deprecated_string, so this StringView is always a dangling
pointer.
Instead, since this string value is an ID and is primarily used as a
FlyString, store it as a FlyString from the get-go.
This was the only remaining codec that produced IndexedN bitmaps.
By removing them, we'll be able to get rid of those formats and simplify
the Bitmap and Painter classes.
Instead of resolving lengths used in the backdrop-filter during
painting, we can do that earlier in apply_style().
This change moves us a bit closer to the point when the stacking
context tree will be completely separated from the layout tree :)
When the outline has focus, arrow keys navigate the outline instead
of changing the current page.
Add opt-up and opt-down as a way to move by one page even when the
outline has focus. (This matches Preview.app.)
xib change: Added two menu Previous Page with key equivalent opt-up
and Next Page with key equivalent opt-down to Go menu and bound them to
goToPreviousPage: and goToNextPage: on First Responder.
When the outline has focus, the responder chain is outline ->
window, so also add the actions on the window controller, and
let that forward to the PDF view.
When this feature was finally merged, the serenity_option in
lagom_options.cmake had the unintended side effect of always setting the
cache variable to "" in the initial cache. In order to actually set the
linker to use to be lld or mold, we need to set with the FORCE flag in
the use_linker.cmake file.
Found by checking with the CMake variable_watch() function.
This will stop the build from spamming the "Using LLD to link Lagom"
message all over the place :^)
The original doc comment was mistakenly copy-pasted from
count_leading_zeroes_safe, and incorrect. The function is doing
something else: it's counting _trailing_ zeroes instead of _leading_
ones.
Do this with INSTALL_INTERFACE genex include directory rules. We should
really standardize where the generated headers *actually* get installed
to though.
The mentioned functions used m_size / 8 instead of size_in_bytes()
(division with ceiling rounding mode), which resulted in an off-by-one
error such that the functions didn't search in the last not-fully-8-bits
byte.
Using size_in_bytes() instead of m_size / 8 fixes this.
Previously, every time a page switched fonts, we'd completely
re-parse the font.
Now, we cache fonts in Renderer, effectively caching them per page.
It'd be nice to have an LRU cache across pages too, but that's a
bigger change, and this already helps a lot.
Font size is part of the cache key, which means we re-parse the same
font at different font sizes. That could be better too, but again,
it's a big help as-is already.
Takes rendering the 1310 pages of the PDF 1.7 reference with
Build/lagom/bin/pdf --debugging-stats \
~/Downloads/pdf_reference_1-7.pdf
from 71 s to 11s :^)
Going through pages especially in the index is noticeably snappier.
(On the PDF 2.0 spec, ISO_32000-2-2020_sponsored.pdf, it's less
dramatic: From 19s to 16s.)
This allows the decoder to fail gracefully when reading a partial or
malformed TBSCertificate. We also now ensure that the certificate data
is valid before making a copy of it.
493dd5d93c caused the `::before`
pseudo-element node to be inserted before the element's content, which
caused issues with how we determine where to insert inline nodes into
the layout tree. At the time, I noticed the issue with contents of flex
containers, and prevented them from merging into a `::before` box.
However, a similar situation happens when we're not in a flex container,
but the pseudo-element has `display: block`. This commit fixes that
situation by using the same logic in both places, so a similar mistake
can't be made again.
This fixes the tab text being invisible on GitHub project pages. :^)
I broke this when moving from a xib file to creating the UI in code.
https://developer.apple.com/documentation/appkit/nsuserinterfaceitemidentification/1396829-identifier
says:
"Identifiers are used during window restoration operations to uniquely
identify the windows of the application. [...] If you create an item in
Interface Builder and do not set a value for this string, a unique value
is created for the item when the nib file is loaded. For
programmatically created views, you typically set this value after
creating the item but before adding it to a window."
Without this, encodeRestorableStateWithCoder: / restoreStateWithCoder:
in MacPDFView weren't getting called.
The documentation is very loud about cell-based things being
deprecated, but it's fairly hidden what to actually do to switch to
the non-deprecated way (implement a certain delegate method).
Session 120 from WWDC 2011 has some notes on this. Apple's official
site no longer seems to have that, but it's e.g. here:
https://docs.huihoo.com/apple/wwdc/2011/session_120__view_based_nstableview.pdf
Just setting headerView to nil removes the header, but also has
the effect of no longer drawing the outline view with a sidebar
background ¯\_(ツ)_/¯.
But also setting drawsBackground to NO on the scroll view restores
the sidebar look, so do that too.
With this, it is no longer necessar to explicitly set style.
The default NSTableViewStyleAutomatic now seems to resolve to
NSTableViewStyleSourceList, so stop explicitly setting it.
(This part has no behavior change.)
Clicking an item in the outline now opens that page.
This requires giving the outline view a delegate, which for some
reason also has th effect of indenting expandable items ¯\_(ツ)_/¯
The vertical alignment of text still looks off, though.
The outline has drawing artifacts, but it is somewhat functional:
You can click on disclosure triangles to open outline items, and
if the outline doesn't fit in the sidebar, it's scrollable.
The outline view has the correct sidebar look: gray with a slightly
transparent glass effect.
Clicking items doesn't have an effect yet.
