* src/select/Makefile: the select_generator target is PHONYHEADmasterMichael Orlitzky7 days1-0/+1
| | | | | | This target doesn't create an object named "select_generator", so it can be marked .PHONY to improve performance slightly and to avoid a conflict with files/directories of the same name.
* src/stylesheet.h: set uses_revert flag for shorthand propertiesMichael Orlitzky8 days1-1/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Take for example the list-style and list-style-type properties; the former is a shorthand property that subsumes the latter. When the list-style-type property is parsed, the "flags" variable has its FLAG_REVERT bit set, and we call, css__stylesheet_style_appendOPV(result, CSS_PROP_LIST_STYLE_TYPE, flags, value); which then sets the "uses_revert" bit on the stylesheet: if ((flags & (0x7 << 1)) == FLAG_REVERT) { style->sheet->uses_revert = true; } In contrast, when list-style is parsed and a flag is found, we run error = css_stylesheet_style_flag_value(result, flag_value, CSS_PROP_LIST_STYLE_TYPE); which immediately delegates to css__stylesheet_style_append() and buildOPV() without checking if "uses_revert" needs to be set. This can lead to segfault when we try to revert to a state that we have not saved (Mantis bug 2854). Adding a FLAG_REVERT check to css_stylesheet_style_flag_value() fixes the issue for the shorthand properties listed in docs/Bytecode, most (but not all) of which experienced the crash.

* select: generator: Remove dead codeMichael Drake2022-12-032-150/+36
| | | | | | | | | | This doesn't change the output of the generator at all. It removes the capability to handle property groups, which has been unused since property grouping was removed. Property grouping was originally an attempt to reduce computed style size, which became redundant complexity when computed styles became interned.
