* Socket: fix win32/aos3 buildJohn-Mark Bell2024-03-131-5/+0
|
* Fetch/curl: expose socket open/close via fetch vtableJohn-Mark Bell2024-03-131-0/+20
| | | | | This allows frontends to customise the behaviour of sockets. The default implementation simply maps to socket(2)/close(2).
* fetchers: drop support for ancient OpenSSLJohn-Mark Bell2024-03-132-328/+31
| | | | | | | | | We now require 1.1.1 or later (and, preferably, 3.x). Also take the opportunity to add support for LibreSSL 3.5.0 or later (we still support ancient versions of this because 3.5.0 is still relatively modern -- give it a few more years and support for old LibreSSL can go, too)

* Revert "fetchers: drop support for ancient OpenSSL"John-Mark Bell2024-02-112-31/+328
| | | | | | | ciworker{8,12} (respectively: FreeBSD, aarch64 Linux) are running obsolete OS versions. Disappointment ensues. This reverts commit 6bb70e88108c904d67e9af7c8e5b273f6cd6854f.

* fetchers/curl: modernise TLS 1.2 cipher suitesJohn-Mark Bell2024-02-041-8/+25
| | | | | | | | | * Drop support for DHE completely (logjam plus compat woes caused other browsers to do this some time ago) * Minimise CBC-mode suites * Fall back to non-PFS RSA suites if really necessary (we treat this as a protocol downgrade as anything modern should either be using TLS 1.3 or have support for the ECDHE suites)
* HSTS: propagate enabled state for HTTPS URLs, tooJohn-Mark Bell2024-01-201-2/+9
| | | | | | | While we have no need to transform the URL in the HTTPS case, the HSTS policy should still result in a hard failure when something is untoward (i.e. not providing the user with a way to proceed). Ensure this is so.
* content/textplain: fix U+FFFD encodingJohn-Mark Bell2023-12-211-1/+1

* Resolve progress function deprication in curl later than 7.32.0Vincent Sanders2023-12-121-6/+16

* jpegxl: Ensure decoded bitmap format is converted to front end formatMichael Drake2023-11-261-1/+13
|
* jpegxl: Tell libjxl to decode unpremultiply alpha if neededMichael Drake2023-11-261-0/+9
| | | | On some platforms our bitmap format does not use premultiplied alpha.
* jpegxl: Designated initialiser for output format structMichael Drake2023-11-261-1/+6
| | | | So I could see the meanings of how we'd set up the decode.

|
* html: Avoid fetching (and decoding) linked stylesheetsMichael Drake2023-11-261-0/+4
| | | | | When the `author_level_css` option is disabled, avoid fetching stylesheets that won't be used for selection.

* html: layout: Ensure all object types are reflowed if appropriateMichael Drake2023-11-251-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The SVGTiny content handler uses the reflow method to set the content width/height. The when the content first broadcasts "done", the HTML handler checks if there had already been a layout. If there has, it calls the SVG's content reflow method with the box dimensions. If not, it calls the reflow method with width/height zero. Since the layout code was only reflowing objects if they were HTML, these SVG contents were never getting their actual dimensions. The result of this was that when we came to plot these SVGs we were dividing by zero in the building of the transformation matrix: transform[0] = (float) width / (float) c->width; ... transform[3] = (float) height / (float) c->height; These divided the plot size by the content size. The result of this on the GTK front end was infinities in the transformation matrix passed to Cairo, and the turning of the whole nsgtk window into a glitchy ruin while the SVG was on screen. It may have affected other front ends too; these divide by zeros were happening in the core, and passed to the front ends' plotters. This issue only affected SVGs on HTML pages, and not when viewed directly. Also the SVGs had to be completely fetched and converted before the document had undergone layout. This was the case with SVGs at the top of both Wikipedia and The Register. In both cases the glitching window would be fixed by scrolling down the page past the SVG.
* css: Add option to ignore author level CSSMichael Drake2023-11-253-5/+17
| | | | | | | | | | | | This adds a new config option, `author_level_css`. When it is disabled, NetSurf will ignore all CSS from the web page. In this case only the default CSS rules from the browser and user CSS rules will be applied. It is enabled by default. Tested by running: ./nsgtk3 --author_level_css=0

* fetchers/curl: tolerate lack of TLS1.3John-Mark Bell2023-03-051-2/+6
| | | | | | | | If we are building against a modern version of libcurl, but it was built against a version of OpenSSL that does not support TLS1.3, then attempting to configure TLS1.3 ciphersuites will fail with CURLE_NOT_BUILT_IN. Tolerate this scenario by treating such a return code as non-fatal in this case.
