Public bug reported: IMPACT ------- Evince does not follow internal links in some PDF research articles (affects Evince 3.28.4 + Poppler 0.62.0 on Ubuntu 18.04) https://gitlab.gnome.org/GNOME/evince/issues/1070
PDF's link annotation does not work in Evince 3.30.2 https://gitlab.gnome.org/GNOME/evince/issues/1027 Evince does not follow internal links in some PDF research articles. The internal links are used for easy and fast navigation to pages, figures, references and equations. qpdfview (poppler-qt5 viewer) can follow the internal links in those files just fine. DOI of one of the affected documents: http://dx.doi.org/10.1016/j.apenergy.2016.10.058 Upstream fix: https://gitlab.freedesktop.org/poppler/poppler/commit/44505cb397c46baa7dd4a0456f737f36e6d19ad0 TEST CASE ---------- Clicking on the following parts should work after the fix is committed: - Superscripts next to the authors names - Citations in page 17 (e.g. [1], [9,11-18], [25-30]) - Figure and Table links in page 17 (Fig 1 and Table 1 at the beginning of section 2) - Equations in page 19 (they stay in the same page as the equations are very close to their links) REGRESSION POTENTIAL --------------------- This is quoted from the upstream commit: "Named destinations may be described by bytestrings, containing embedded NULs and not being NUL terminated. That means they cannot be exposed directly as char*. The alternatives are to escape the string from the internal representation when exposing it in the API (e.g. in PopplerDest.named_dest), or to add parallel API exposing it as GString, or GBytes. This patch chooses the first option, since the presence of these named destionations in the public, not sealed, PopplerDest struct means that the second option would need more API additions. The chosen option is simpler, and does not need the API users to adapt unless they create the named dest strings themselves, or consume them in ways other than calling poppler APIs. The escaping scheme chosen simply replaces embedded NUL with "\0" and escapes a literal backslash with "\\". This is a minimal ABI change in that some strings that previously worked unchanged as destinations (those containing backslash) now don't work, but on the other hand, previously it was impossible to use any destinations containing embedded NULs. Add poppler_named_dest_{from,to}_bytestring() to perform that conversion, and clarify the documentation for when you need them."
