| 2019-07-09 | Rename common to gdbsupport | Tom Tromey | 1 | -1/+1 | |
| This is the next patch in the ongoing series to move gdbsever to the top level. This patch just renames the "common" directory. The idea is to do this move in two parts: first rename the directory (this patch), then move the directory to the top. This approach makes the patches a bit more tractable. I chose the name "gdbsupport" for the directory. However, as this patch was largely written by sed, we could pick a new name without too much difficulty. Tested by the buildbot. gdb/ChangeLog 2019-07-09 Tom Tromey <tom@tromey.com> * contrib/ari/gdb_ari.sh: Change common to gdbsupport. * configure: Rebuild. * configure.ac: Change common to gdbsupport. *

| 2019-01-01 | Update copyright year range in all GDB files. | Joel Brobecker | 1 | -1/+1 | |
| This commit applies all changes made after running the gdb/copyright.py script. Note that one file was flagged by the script, due to an invalid copyright header (gdb/unittests/basic_string_view/element_access/char/empty.cc). As the file was copied from GCC's libstdc++-v3 testsuite, this commit leaves this file untouched for the time being; a patch to fix the header was sent to gcc-patches first. gdb/ChangeLog: Update copyright year range in all GDB files. | |||||
| 2018-08-07 | Add DWARF index cache | Simon Marchi | 1 | -0/+11 | |
| New in v3: - Remove things related to the dwarf-5 format. - Fix compilation on mingw (scoped_mmap.c). GDB can generate indexes for DWARF debug information, which, when integrated in the original binary, can speed up loading object files. This can be done using the gdb-add-index script or directly by the linker itself. However, not many people know about this. And even among those who do, because it requires additional steps, I don't know a lot of people who actually go through that trouble. To help make using the DWARF index more transparent, this patch introduces a DWARF index cache. When enabled, loading an index-less binary in GDB will automatically save an index file in ~/.cache/gdb. When loading that same object file again, the index file will be looked up and used to load the DWARF index. You therefore get the benefit of the DWARF index without having to do additional manual steps or modifying your build system. When an index section is already present in the file, GDB will prefer that one over looking up the cache. When doing my edit-compile-debug cycle, I often debug multiple times the same build, so the cache helps reducing the load time of the debug sessions after the first one. - The saved index file is exactly the same as the output of the "save gdb-index" command. It is therefore the exact same content that would be found in the .gdb_index or .debug_names section. We just leave it as a standalone file instead of merging it in the binary. - The cache is just a directory with files named after the object file's build-id. It is not possible to save/load the index for an object file without build-id in the cache. - The cache uses the gdb index format. The problem with the dwarf-5 format is that we can generate an addendum to the .debug_str section that you're supposed to integrate to the original binary. This complicates a little bit loading the data from the cached index files, so I would leave this for later. - The size taken up by ~/.cache/gdb is not limited. I was thinking we could add configurable limit (like ccache does), but that would come after. Also, maybe a command to flush the cache. - The cache is disabled by default. I think once it's been out there and tested for a while, it could be turned on by default, so that everybody can enjoy it. - The code was made to follow the XDG specification: if the XDG_CACHE_HOME environment variable, it is used, otherwise it falls back to ~/.cache/gdb. It is possible to change it using "set index-cache directory". On other OSes than GNU/Linux, ~/.cache may not be the best place to put such data. On macOS it should probably default to ~/Library/Caches/... On Windows, %LocalAppData%/... I don't intend to do this part, but further patches are welcome. - I think that we need to be careful that multiple instances of GDB don't interfere with each other (not far fetched at all if you run GDB in some automated script) and the cache is always coherent (either the file is not found, or it is found and entirely valid). Writing the file directly to its final location seems like a recipe for failure. One GDB could read a file in the index while it is being written by another GDB. To mitigate this, I made write_psymtabs_to_index write to temporary files and rename them once it's done. Two GDB instances writing the index for the same file should not step on each other's toes (the last file to be renamed will stay). A GDB looking up a file will only see a complete file or no file. Also, if GDB crashes while generating the index file, it will leave a work-in-progress file, but it won't be picked up by other instances looking up in the cache. gdb/ChangeLog: * common/pathstuff.h (get_standard_cache_dir): New. * common/pathstuff.c (get_standard_cache_dir): New. * build-id.h (build_id_to_string): New. * dwarf-index-common.h (INDEX4_SUFFIX, INDEX5_SUFFIX, DEBUG_STR_SUFFIX): Move to here. * dwarf-index-write.c (INDEX4_SUFFIX, INDEX5_SUFFIX, DEBUG_STR_SUFFIX): Move from there.

| 2017-01-10 | Use class to manage BFD reference counts | Tom Tromey | 1 | -2/+4 | |
| This introduces a new specialization of gdb::ref_ptr that can be used to manage BFD reference counts. Then it changes most places in gdb to use this new class, rather than explicit reference-counting or cleanups. This patch removes make_cleanup_bfd_unref. If you look you will see a couple of spots using "release" where a use of gdb_bfd_ref_ptr would be cleaner. These will be fixed in the next patch. I think this patch fixes some latent bugs. For example, it seems to me that previously objfpy_add_separate_debug_file leaked a BFD. I'm not 100% certain that the macho_symfile_read_all_oso change is correct. The existing code here is hard for me to follow. One goal of this sort of automated reference counting, though, is to make it more difficult to make logic errors; so hopefully the code is clear now. 2017-01-10 Tom Tromey <tom@tromey.com> * windows-tdep.c (windows_xfer_shared_library): Update. * windows-nat.c (windows_make_so): Update. * utils.h (make_cleanup_bfd_unref): Remove. * utils.c (do_bfd_close_cleanup, make_cleanup_bfd_unref): Remove. * symfile.h (symfile_bfd_open) (find_separate_debug_file_in_section): Return gdb_bfd_ref_ptr. * symfile.c (read_symbols, symbol_file_add) (separate_debug_file_exists): Update.

| 2015-06-15 | Allow gdb to find debug symbols file by build-id for PE file format also | Jon Turney | 1 | -1/+1 | |
| This promotes BFD's struct elf_build_id to the generic struct bfd_build_id, populated when an ELF or PE BFD is read. gdb is updated to use that, and to use the build-id to find symbols for PE files also.

| 2013-10-08 | fix PR symtab/15597 | Tom Tromey | 1 | -0/+44 | |
| This patch fixes gdb PR symtab/15597. The bug is that the .gnu_debugaltlink section includes the build-id of the alt file, but gdb does not use it. This patch fixes the problem by changing gdb to do what it ought to always have done: verify the build id of the file found using the filename in .gnu_debugaltlink; and if that does not match, try to find the correct debug file using the build-id and debug-file-directory. This patch touches BFD. Previously, gdb had its own code for parsing .gnu_debugaltlink; I changed it to use the BFD functions after those were introduced. However, the BFD functions are incorrect -- they assume that .gnu_debugaltlink is formatted like .gnu_debuglink. However, it it is not. Instead, it consists of a file name followed by the build-id -- no alignment, and the build-id is not a CRC. Fixing this properly is a bit of a pain. But, because separate_alt_debug_file_exists just has a FIXME for the build-id case, I did not fix it properly. Instead I introduced a hack. This leaves BFD working just as well as it did before my patch. I'm willing to do something better here but I could use some guidance as to what. It seems that the build-id code in BFD is largely punted on. FWIW gdb is the only user of bfd_get_alt_debug_link_info outside of BFD itself. I moved the build-id logic out of elfread.c and into a new file. This seemed cleanest to me. Writing a test case was a bit of a pain. I added a couple new features to the DWARF assembler to handle this. Built and regtested on x86-64 Fedora 18. * bfd-in2.h: Rebuild. * opncls.c (bfd_get_alt_debug_link_info): Add buildid_len parameter. Change type of buildid_out. Update.
