2023-01-01Update copyright year range in header of all files managed by GDBJoel Brobecker1-1/+1
This commit is the result of running the gdb/copyright.py script, which automated the update of the copyright year range for all source files managed by the GDB project to be updated to include year 2023.
2022-11-28gdb/testsuite: remove use of then keyword from gdb.base/*.expAndrew Burgess1-1/+1
The canonical form of 'if' in modern TCL is 'if {} {}'. But there's still a bunch of places in the testsuite where we make use of the 'then' keyword, and sometimes these get copies into new tests, which just spreads poor practice. This commit removes all use of the 'then' keyword from the gdb.base/ test script directory. There should be no changes in what is tested after this commit.
2022-04-26gdb/testsuite: use with_cwd where possibleSimon Marchi1-22/+19
I learned about with_cwd today. I spotted a few spots that could use it, to make the code more robust. Change-Id: Ia23664cb827f25e79d31948e0c006a8dc61c33e1
2022-01-01Automatic Copyright Year update after running gdb/copyright.pyJoel Brobecker1-1/+1
This commit brings all the changes made by running gdb/copyright.py as per GDB's Start of New Year Procedure. For the avoidance of doubt, all changes in this commits were performed by the script.
2021-09-30gdb/testsuite: make runto_main not pass no-message to runtoSimon Marchi1-1/+0
As follow-up to this discussion: https://sourceware.org/pipermail/gdb-patches/2020-August/171385.html ... make runto_main not pass no-message to runto. This means that if we fail to run to main, for some reason, we'll emit a FAIL. This is the behavior we want the majority of (if not all) the time. Without this, we rely on tests logging a failure if runto_main fails, otherwise. They do so in a very inconsisteny mannet, sometimes using "fail", "unsupported" or "untested". The messages also vary widly. This patch removes all these messages as well. Also, remove a few "fail" where we call runto (and not runto_main). by default (without an explicit no-message argument), runto prints a failure already. In two places, gdb.multi/multi-re-run.exp and gdb.python/py-pp-registration.exp, remove "message" passed to runto. This removes a few PASSes that we don't care about (but FAILs will still be printed if we fail to run to where we want to). This aligns their behavior with the rest of the testsuite.

2021-02-27[PR gdb/27393] set directories: handle empty dirs.Lancelot SIX1-0/+41
As reported in gdb/27393, the 'directory' and 'set directories' commands fail when parsing an empty dir name: (gdb) set directories "" /home/lsix/dev/gnu/binutils-gdb/gdbsupport/pathstuff.cc:132: internal-error: gdb::unique_xmalloc_ptr<char> gdb_abspath(const char*): Assertion `path != NULL && path[0] != '\0'' failed. or (gdb) dir : /home/lsix/dev/gnu/binutils-gdb/gdbsupport/pathstuff.cc:132: internal-error: gdb::unique_xmalloc_ptr<char> gdb_abspath(const char*): Assertion `path != NULL && path[0] != '\0'' failed. This patch fixes this issue by ignoring any attempt to add an empty name to the source directories list. 'set dir ""' will reset the directories list the same way 'set dir' would do it. Tested on x86_64.

2020-06-22Disable parts of gdb.base/source-dir.exp on remote hostSandra Loosemore1-1/+11
One set of tests in this file does a lot of complicated directory manipulations to force a specific DW_AT_comp_dir format and gdb directory search path. As it's written, everything assumes host == build, and it does not seem to me that there is any obvious way to rewrite this so it will work in general on remote host. For instance, our harness for testing on remote Windows host normally does all compilation and GDB execution in $cwd using relative pathnames and I'm not sure all these directory tricks would set up the scenario it's trying to test even if they were correctly performed on host rather than build. So I think it's reasonable just to disable this on remote host instead. I also noted that it's using the wrong search path syntax for Windows host in the "set directories" command and conditionalized that while I was looking at it. That's a necessary fix to make this work in a situation where host == build and it's Windows, but I'm not actually set up to test that it's sufficient, too. 2020-06-22 Sandra Loosemore <sandra@codesourcery.com> gdb/testsuite/ * gdb.base/source-dir.exp (test_truncated_comp_dir): Skip on remote host. Fix search path syntax on Windows host.

2019-09-17gdb: Look for compilation directory relative to directory search pathMike Gulick1-4/+137
The 'directory' command allows the user to provide a list of filesystem directories in which to search for source code. The directories in this search path are used as the base directory for the source filename from the debug information (DW_AT_name). Thus the directory search path provides alternatives to the existing compilation directory from the debug information (DW_AT_comp_dir). Generally speaking, DW_AT_name stores the filename argument passed to the compiler (including any directory components), and DW_AT_comp_dir stores the current working directory from which the compiler was executed. For example: $ cd /path/to/project/subdir1 $ gcc -c a/test.c -g The corresponding debug information will look like this: DW_AT_name : a/test.c DW_AT_comp_dir : /path/to/project/subdir1 When compiling with the -fdebug-prefix-map GCC option, the compilation directory can be arbitrarily rewritten. In the above example, we may rewrite the compilation directory as follows: $ gcc -c a/test.c -g -fdebug-prefix-map=/path/to/project= In this case, the corresponding debug information will look like: DW_AT_name : a/test.c DW_AT_comp_dir : /subdir1 This prevents GDB from finding the corresponding source code based on the debug information alone. In some cases, a substitute-path command can be used to re-map a consistent prefix in the rewritten compilation directory to the real filesystem path. However, there may not be a consistent prefix remaining in the debug symbols (for example in a project that has source code in many subdirectories under the project's root), thereby requiring multiple substitute-path rules. In this case, it is easier to add the missing prefix to the directory search path via the 'directory' command. The function find_and_open_source currently searches in: SEARCH_PATH/FILENAME where SEARCH_PATH corresponds to each individual entry in the directory search path (which is guaranteed to contain the compilation directory from the debug information, as well as the current working directory). FILENAME corresponds to the source filename (DW_AT_name), which may have directory components in it. In addition, GDB searches in: SEARCH_PATH/FILE_BASENAME where FILE_BASENAME is the basename of the DW_AT_name entry. This change modifies find_and_open_source to additionally search in: SEARCH_PATH/COMP_DIR/FILENAME where COMP_DIR is the compilation directory from the debug symbols. In the example given earlier, running: (gdb) directory /path/to/project will now allow GDB to correctly locate the source code from the debug information. gdb/ChangeLog: * source.c (prepare_path_for_appending): New function. (openp): Make use of new function. (find_and_open_source): Search for the compilation directory and source file as a relative path beneath the directory search path. gdb/doc/ChangeLog: * gdb.texinfo (Source Path): Additional text to better describe how the source path directory list is used when searching for source files. gdb/testsuite/ChangeLog: * gdb.base/source-dir.exp: Add extra test for mapped compilation directory.
2019-01-01Update copyright year range in all GDB files.Joel Brobecker1-1/+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.
