From 9ac37a9ce607b790bea17c7782d73afecaaa916c Mon Sep 17 00:00:00 2001 From: Aaron Merey Date: Fri, 19 Nov 2021 19:41:40 -0500 Subject: [PATCH] PR gdb/27876 - debuginfod-downloaded source files don't pass proper fullname across mi / (gdb)info source Source files downloaded from debuginfod currently use their original DWARF filename as their "fullname". This causes a mismatch between the fullname and the actual location of the source file in the debuginfod client cache. MI consumers such as VSCode will fail to open debuginfod-downloaded source files due to this. Also 'info source' will fail to include the true paths of these files. To fix this, use the debuginfod cache path as the fullname for debuginfod- downloaded source files. --- gdb/debuginfod-support.c | 5 +++-- 1 file changed, 3 insertions(+), 2 deletions(-) diff --git a/gdb/debuginfod-support.c b/gdb/debuginfod-support.c index 56d8e7781c5..b44ce67c340 100644 --- a/gdb/debuginfod-support.c +++ b/gdb/debuginfod-support.c @@ -202,6 +202,7 @@ debuginfod_source_query (const unsigned char *build_id, if (c == nullptr) return scoped_fd (-ENOMEM); + char *dname = nullptr; user_data data ("source file", srcpath); debuginfod_set_user_data (c, &data); @@ -216,7 +217,7 @@ debuginfod_source_query (const unsigned char *build_id, build_id, build_id_len, srcpath, - nullptr)); + &dname)); debuginfod_set_user_data (c, nullptr); if (debuginfod_verbose > 0 && fd.get () < 0 && fd.get () != -ENOENT) @@ -225,7 +226,7 @@ debuginfod_source_query (const unsigned char *build_id, styled_string (file_name_style.style (), srcpath)); if (fd.get () >= 0) - *destname = make_unique_xstrdup (srcpath); + destname->reset (dname); return fd; } -- 2.30.2
