From f2f861f017bd598c9e5b72f64e10587cbe1e3405 Mon Sep 17 00:00:00 2001 From: Stephan Witt Date: Sat, 22 Feb 2020 12:11:42 +0100 Subject: [PATCH] Use real path names for buffer lookup by name of temporary external files. In case of path names for external files containing symbolic links the real path and the logical path name may be different for the same file or directory. LyX is using QDir::tempPath() to create the path name of the temporary directory. The Qt implementation is free to return the logical or the real path name here and it happens to be different for various platforms and versions. The most stable and clean solution is to use the real path name consistently. --- development/MacOSX/lyxeditor | 4 +--- src/BufferList.cpp | 5 +++-- src/BufferList.h | 5 +++-- src/frontends/qt/GuiView.cpp | 16 +++++----------- 4 files changed, 12 insertions(+), 18 deletions(-) diff --git a/development/MacOSX/lyxeditor b/development/MacOSX/lyxeditor index d24373c7b8..1cd3b76b4e 100755 --- a/development/MacOSX/lyxeditor +++ b/development/MacOSX/lyxeditor @@ -82,9 +82,7 @@ test -z "${LYXPIPE}" && { } if [ -n "$LYXPIPE" -a -p "$LYXPIPE".in ]; then - file=$(echo "$1" | sed 's|^/private||') - - MAC_LYXPIPE_CONTENTS="LYXCMD:macdvix:server-goto-file-row:$file $2" + MAC_LYXPIPE_CONTENTS="LYXCMD:macdvix:server-goto-file-row:$1 $2" # echo "$MAC_LYXPIPE_CONTENTS" echo "$MAC_LYXPIPE_CONTENTS" > "${LYXPIPE}".in || { echo "Cannot write to lyxpipe." ; exit 2 ; } while read line ; do diff --git a/src/BufferList.cpp b/src/BufferList.cpp index fe8caf8c1f..264facd3b3 100644 --- a/src/BufferList.cpp +++ b/src/BufferList.cpp @@ -318,10 +318,11 @@ Buffer * BufferList::getBuffer(support::FileName const & fname, bool internal) c } -Buffer * BufferList::getBufferFromTmp(string const & s) +Buffer * BufferList::getBufferFromTmp(string const & s, bool realpath) { for (Buffer * buf : bstore) { - if (prefixIs(s, buf->temppath())) { + string const temppath = realpath ?
