2018-07-19libmakepkg/tidy: fix debug sources not being properly detected sometimesEli Schwartz
DW_AT_comp_dir is meant to contain the directory in which the compiler was run DW_AT_name contains the source file the compiler was told to use. In the event that DW_AT_name is an absolute path, it is (obviously) not meant to be computed relative to DW_AT_comp_dir. However, we did not handle this correctly, and as a result tried to copy source files using doubled-up filepaths. The correct approach should be to use DW_AT_name on its own, in the event that it is an absolute path. See http://wiki.dwarfstd.org/index.php?title=Best_Practices. This fixes debug package generation for many packages that use absolute paths in their build systems... like CMake.

2018-05-12libmakepkg: Support file 5.33's application/x-pie-executableJan Alexander Steffens (heftig)
file 5.33 introduces a new MIME type "application/x-pie-executable", which is used for relocatable binaries. makepkg ignored these binaries and did not attempt to strip them. Handle the new MIME type like the old "application/x-sharedlib". Stripping the binaries with --strip-unneeded to keep relocation information should be the correct thing to do. file 5.33 also misidentifies actual libraries as PIE executables, so we didn't strip any shared libraries, either. We now work around this bug. Signed-off-by: Jan Alexander Steffens (heftig) <jan.steffens@gmail.com> Signed-off-by: Allan McRae <allan@archlinux.org>

2018-01-10Fix moving source files into debug packagesAllan McRae
Commit 8bec63bf92d8dd028aa88dbd5109c314cdb9ebea attempted to switch to using -fdebug-prefix-map to set file locations in debug packages. It make a few mistakes... 1) Adding debug C{,XX}FLAGS only worked if DBGSRCDIR was defined in makepkg.conf. Fix this by falling back to the default value. 2) Using -fdebug-prefix-map altered a lot of assumptions about file locations when copying source files into debug packages. This resulted in lots of messages of failed cp in packaging output. Signed-off-by: Allan McRae <allan@archlinux.org>
2017-12-07makepkg: tell the compiler to record debugging info for debug packagesEli Schwartz
In commit 8b0d59b83a60eb504567590346119fe4cd891cad support was added for storing the source files of binaries in debug packages. This made use of the debugedit program which is part of the RPM package manager, which is not very standalone. The same effect can be achieved using -fdebug-prefix-map, an option accepted by both the gcc and clang compilers which modifies how the compiler itself stores the references to the source files rather than requiring us to later edit the produced binaries. This also removes the dependency on external programs like debugedit. As a result of this change, source files will only be effectively added for programs which actually use the exported CFLAGS. This is a reasonable tradeoff as we expect our CFLAGS to be used rather than ignored. Upstream software which do not produce useful debug packages are expected to fix their build systems to respect the environment CFLAGS. As a result of this change, the routine for extracting source filenames from binaries had to be modified to derive the source file from the final debug location, rather than the other way around.

2017-01-04Provide source files for useful debug packagesAllan McRae
Debug packages are fairly useless currently because the soucre files needed for stepping through code etc are not packaged with them. This patch adds the needed source files to the debug package and adjusts the debug info to look at the /usr/src/debug/ directory for them rather than the build location. This requires using the "debugedit" program which is provided as part of the RPM sources. Signed-off-by: Allan McRae <allan@archlinux.org>

2016-12-05Build a single debug package for all packages from a PKGBUILDAllan McRae
We want to provide source files with debug symbol packages to allow easy stepping through the program. This becomes difficult with split packages due to the binaries in many of these sharing source files across packages. There are (at least) two solutions to this problem. #1: ensure common source files are located in the debug package for the package lowest in the dependency chain and add dependencies to the debug packages so all require source files are present, or #2: create one debug package for all split packages in a PKGBUILD. The second is a more robust approach despite potentially creating very large debug packages. This patch creates a single $pkgbase-debug package and adds provides such that installing $pkgname-debug will always work. Signed-off-by: Allan McRae <allan@archlinux.org>

To add a new packaging option, drop a file into libmakepkg/tidy that contains a 'packaging_options+=('<option>') and a function that implements that option. The function needs added to the 'tidy_remove' array if it removes files or the 'tidy_modify' array otherwise. Signed-off-by: Allan McRae <allan@archlinux.org>
