Conditionally enable double key logic according to:
private browsing mode or privacy.thirdparty.isolate preference and
implement in GetCookieStringCommon and FindCookie where it counts...
With some reservations of how to convince FindCookie users to test
condition and pass a nullptr when disabling double key logic.
1 Due to our use of `libtool' to generate and install the FreeType 2
2 libraries on Unix systems, as well as other historical events, it is
3 generally very difficult to know precisely which release of the font
4 engine is installed on a given system.
6 This file tries to explain why and to document ways to properly detect
7 FreeType on Unix.
10 1. Version and Release numbers
11 ------------------------------
13 For each new public release of FreeType 2, there are generally *three*
14 distinct `version' numbers to consider:
16 * The official FreeType 2 release number, like 2.3.1 or 2.4.10.
18 * The libtool (and Unix) specific version number, like 13.0.7. This
19 is what `freetype-config --version' returns.
21 * The platform-specific shared object number, used for example when
22 the library is installed as `/usr/lib/libfreetype.so.6.7.1'.
24 The platform-specific number is, unsurprisingly, platform-specific and
25 varies with the operating system you are using (several variants of
26 Linux, FreeBSD, Solaris, etc.). You should thus _never_ use it, even
27 for simple tests.
29 The libtool-specific number does not equal the release number but is
30 tied to it.
32 The release number is available at *compile* time through the following
33 macros defined in FT_FREETYPE_H:
35 - FREETYPE_MAJOR: major release number
36 - FREETYPE_MINOR: minor release number
37 - FREETYPE_PATCH: patch release number
39 See below for a small autoconf fragment.
41 The release number is also available at *runtime* through the
42 `FT_Library_Version' API.
45 2. History
46 ----------
48 The following table gives, for all releases since 2.3.0, the
49 corresponding libtool number, as well as the shared object number found
50 on _most_ systems, but not all of them:

87 3. Autoconf Code Fragment
88 -------------------------
90 Lars Clausen contributed the following autoconf fragment to detect which
91 version of FreeType is installed on a system. This one tests for a
92 version that is at least 2.0.9; you should change it to check against
93 other release numbers.
96 AC_MSG_CHECKING([whether FreeType version is 2.0.9 or higher])
97 old_CPPFLAGS="$CPPFLAGS"
98 CPPFLAGS=`freetype-config --cflags`
99 AC_TRY_CPP([
101 #include <ft2build.h>
102 #include FT_FREETYPE_H
103 #if (FREETYPE_MAJOR*1000 + FREETYPE_MINOR)*1000 + FREETYPE_PATCH < 2000009
104 #error Freetype version too low.
105 #endif
106 ],
107 [AC_MSG_RESULT(yes)
108 FREETYPE_LIBS=`freetype-config --libs`
109 AC_SUBST(FREETYPE_LIBS)
110 AC_DEFINE(HAVE_FREETYPE,1,[Define if you have the FreeType2 library])
111 CPPFLAGS="$old_CPPFLAGS"],
112 [AC_MSG_ERROR([Need FreeType library version 2.0.9 or higher])])
