2020-11-23gmp-utils: Convert the read/write methods to using gdb::array_viewJoel Brobecker1-8/+8
This commit changes the interfaces of some of the methods declared in gmp-utils to take a gdb::array_view of gdb_byte instead of a (gdb_byte *, size) couple. This makes these methods' API probably more C++-idiomatic. * gmp-utils.h (gdb_mpz::read): Change buf and len parameters into one single gdb::array_view parameter. (gdb_mpz::write): Likewise. (gdb_mpq::read_fixed_point, gdb_mpq::write_fixed_point): Likewise. * gmp-utils.c (gdb_mpz::read): Change buf and len parameters into one single gdb::array_view parameter. Adjust implementation accordingly. (gdb_mpz::write): Likewise. (gdb_mpq::read_fixed_point, gdb_mpq::write_fixed_point): Likewise. * unittests/gmp-utils-selftests.c: Adapt following changes above. * valarith.c, valops.c, valprint.c, value.c: Likewise.
2020-11-24Fix stack smashing error during gdb_mpq_write_fixed_point selftestJoel Brobecker1-1/+1
When building GDB using Ubuntu 20.04's system libgmp and compiler, running the "maintenance selftest" command triggers the following error: | Running selftest gdb_mpq_write_fixed_point. | *** stack smashing detected ***: terminated | [1] 1092790 abort (core dumped) ./gdb gdb This happens while trying to construct an mpq_t object (a rational) from two integers representing the numerator and denominator. In our test, the numerator is -8, and the denominator is 1. The problem was that the rational was constructed using the wrong function. This is what we were doing prior to this patch: mpq_set_ui (v.val, numerator, denominator); The 'u' in "ui" stands for *unsigned*, which is wrong because numerator and denominator's type is "int". As a result of the above, instead of getting a rational value of -8, we get a rational with a very large positive value (gmp_printf says "18446744073709551608"). From there, the test performs an operation which is expected to write this value into a buffer which was not dimensioned to fit such a number, thus leading GMP into a buffer overflow. This was verified by applying the formula that GMP's documentation gives for the required memory buffer size needed during export: | When an application is allocating space itself the required size can | be determined with a calculation like the following. Since | mpz_sizeinbase always returns at least 1, count here will be at | least one, which avoids any portability problems with malloc(0), | though if z is zero no space at all is actually needed (or written). | | numb = 8*size - nail; | count = (mpz_sizeinbase (z, 2) + numb-1) / numb; | p = malloc (count * size); With the very large number, mpz_sizeinbase returns 66 and thus the malloc size becomes 16 bytes instead of the 8 we allocated. This patch fixes the issue by using the correct "set" function. gdb/ChangeLog: * unittests/gmp-utils-selftests.c (write_fp_test): Use mpq_set_si instead of mpq_set_ui to initialize our GMP rational.

2020-11-15gmp-utils: New API to simply use of GMP's integer/rational/float objectsJoel Brobecker1-0/+460
This API was motivated by a number of reasons: - GMP's API does not handle "long long" and "unsigned long long", so using LONGEST and ULONGEST is not straightforward; - Automate the need to initialize GMP objects before use, and clear them when no longer used. However, this API grew also to help with similar matter such as formatting to a string, and also reading/writing fixed-point values from byte buffers. Dedicated unit testing is also added. gdb/ChangeLog: * gmp-utils.h, gmp-utils.h: New file. * unittests/gmp-utils-selftests.c: New file. * Makefile.in (SUBDIR_UNITTESTS_SRCS): Add unittests/gmp-utils-selftests.c. (COMMON_SFILES) Add gmp-utils.c. (HFILES_NO_SRCDIR): Add gmp-utils.h.
2020-11-02gdb, gdbserver, gdbsupport: fix leading space vs tabs issuesSimon Marchi2-3/+3
Many spots incorrectly use only spaces for indentation (for example, there are a lot of spots in ada-lang.c). I've always found it awkward when I needed to edit one of these spots: do I keep the original wrong indentation, or do I fix it? What if the lines around it are also wrong, do I fix them too? I probably don't want to fix them in the same patch, to avoid adding noise to my patch. So I propose to fix as much as possible once and for all (hopefully). One typical counter argument for this is that it makes code archeology more difficult, because git-blame will show this commit as the last change for these lines. My counter counter argument is: when git-blaming, you often need to do "blame the file at the parent commit" anyway, to go past some other refactor that touched the line you are interested in, but is not the change you are looking for. So you already need a somewhat efficient way to do this. Using some interactive tool, rather than plain git-blame, makes this trivial. For example, I use "tig blame <file>", where going back past the commit that changed the currently selected line is one keystroke. It looks like Magit in Emacs does it too (though I've never used it). Web viewers of Github and Gitlab do it too. My point is that it won't really make archeology more difficult. The other typical counter argument is that it will cause conflicts with existing patches. That's true... but it's a one time cost, and those are not conflicts that are difficult to resolve. I have also tried "git rebase --ignore-whitespace", it seems to work well. Although that will re-introduce the faulty indentation, so one needs to take care of fixing the indentation in the patch after that (which is easy). gdb/ChangeLog: * aarch64-linux-tdep.c: Fix

2020-09-29Tweak gdbsupport/valid-expr.h for GCC 6, fix buildPedro Alves1-7/+17
With GCC 6.4 and 6.5 (at least), unit tests that use gdbsupport/valid-expr.h's CHECK_VALID fail to compile, with: In file included from src/gdb/unittests/offset-type-selftests.c:24:0: src/gdb/unittests/offset-type-selftests.c: In substitution of 'template<class Expected, template<class ...> class Op, class ... Args> using is_detected_exact = std::is_same<Expected, typename gdb::detection_detail::detector<gdb::nonesuch, void, Op, Args ...>::type> [with Expected = selftests::offset_type::off_A&; Op = selftests::offset_type::check_valid_expr75::archetype; Args = {selftests::offset_type::off_A, selftests::offset_type::off_B}]': src/gdb/unittests/offset-type-selftests.c:75:1: required from here src/gdb/../gdbsupport/valid-expr.h:65:20: error: type/value mismatch at argument 2 in template parameter list for 'template<class Expected, template<class ...> class Op, class ... Args> using is_detected_exact = std::is_same<Expected, typename gdb::detection_detail::detector<gdb::nonesuch, void, Op, Args ...>::type>' archetype, TYPES>::value == VALID, \ ^ The important part is the "error: type/value mismatch" error. Seems like that GCC doesn't understand that archetype is an alias template, and is being strict in requiring a template class. The fix here is then to make archetype a template class, to pacify GCC. The resulting code looks like this: template <TYPENAMES, typename = decltype (EXPR)> struct archetype { }; static_assert (gdb::is_detected_exact<archetype<TYPES, EXPR_TYPE>, archetype, TYPES>::value == VALID, ""); is_detected_exact<Expected, Op, Args> checks whether Op<Args> is type Expected: - For Expected, we pass the explicit EXPR_TYPE, overriding the default parameter type of archetype. - For Args we don't pass the last template parameter, so archtype defaults to the EXPR's decltype. So in essence, we're really checking whether EXPR_TYPE is the same as decltype(EXPR). We need to do the decltype in a template context in order to trigger SFINAE instead of failing to compile. The hunk in unittests/enum-flags-selftests.c becomes necessary, because unlike with the current alias template version, this new version makes GCC trigger -Wenum-compare warnings as well: src/gdb/unittests/enum-flags-selftests.c:328:33: error: comparison between 'enum selftests::enum_flags_tests::RE' and 'enum selftests::enum_flags_tests::RE2' [-Werror=enum-compare] CHECK_VALID (true, bool, RE () != RE2 ()) ^ src/gdb/../gdbsupport/valid-expr.h:61:45: note: in definition of macro 'CHECK_VALID_EXPR_INT' template <TYPENAMES, typename = decltype (EXPR)> \ ^ Build-tested with: - GCC {4.8.5, 6.4, 6.5, 7.3.1, 9.3.0, 11.0.0-20200910} - Clang 10.0.0 gdbsupport/ChangeLog: * valid-expr.h (CHECK_VALID_EXPR_INT): Make archetype a template class instead of an alias template and adjust static_assert. gdb/ChangeLog: * unittests/enum-flags-selftests.c: Check whether __GNUC__ is defined before using '#pragma GCC diagnostic' instead of checking __clang__.
2020-09-27Use a curses pad for source and disassembly windowsTom Tromey1-3/+3
This changes the TUI source and disassembly windows to use a curses pad for their text. This is an important step toward properly handling non-ASCII characters, because it makes it easy to scroll horizontally without needing gdb to also understand multi-byte character boundaries -- this can be wholly delegated to curses. Horizontal scrolling is probably also faster now, because no re-rendering is required. gdb/ChangeLog 2020-09-27 Tom Tromey <tom@tromey.com> * unittests/tui-selftests.c: Update. * tui/tui-winsource.h (struct tui_source_window_base) <extra_margin, show_line_number, refresh_pad>: New methods. <m_max_length, m_pad>: New members.

2020-09-15Use arrays rather than pointers for global string constantsTom Tromey1-1/+1
My understanding is that it's mildly better to use a static const array, as opposed to a "const char *", for a global string constant, when possible. This makes sense to me because the pointer requires a load from an address, whereas the array is just the address. So, I searched for these in gdb and gdbserver. This patch fixes the ones I found. gdb/ChangeLog 2020-09-15 Tom Tromey <tromey@adacore.com> * unittests/memory-map-selftests.c (valid_mem_map): Now array. * ui-style.c (ansi_regex_text): Now array. * rust-exp.y (number_regex_text): Now array. * linespec.c (linespec_quote_characters): Now array. * jit.c (jit_break_name, jit_descriptor_name, reader_init_fn_sym): Now arrays. gdbserver/ChangeLog 2020-09-15 Tom Tromey <tromey@adacore.com> * linux-x86-low.cc (xmltarget_i386_linux_no_xml) (xmltarget_amd64_linux_no_xml): Now arrays.
2020-09-14Rewrite enum_flags, add unit tests, fix problemsPedro Alves1-0/+586
This patch started by adding comprehensive unit tests for enum_flags. For the testing part, it adds: - tests of normal expected uses of the API. - checks that _invalid_ uses of the API would fail to compile. I.e., it validates that enum_flags really is a strong type, and that incorrect mixing of enum types would be caught at compile time. It pulls that off making use of SFINEA and C++11's decltype/constexpr. This revealed many holes in the enum_flags API. For example, the f1 assignment below currently incorrectly fails to compile: enum_flags<flags> f1 = FLAG1; enum_flags<flags> f2 = FLAG2 | f1; The unit tests also revealed that this useful use case doesn't work: enum flag { FLAG1 = 1, FLAG2 = 2 }; enum_flags<flag> src = FLAG1; enum_flags<flag> f1 = condition ? src : FLAG2; It fails to compile because enum_flags<flag> and flag are convertible to each other. Turns out that making enum_flags be implicitly convertible to the backing raw enum type was not a good idea. If we make it convertible to the underlying type instead, we fix that ternary operator use case, and, we find cases throughout the codebase that should be using the enum_flags but were using the raw backing enum instead. So it's a good change overall. Also, several operators were missing. These holes and more are plugged by this patch, by reworking how the enum_flags operators are implemented, and making use of C++11's feature of being able to delete methods/functions. There are cases in gdb/compile/ where we need to call a function in a C plugin API that expects the raw enum. To address cases like that, this adds a "raw()" method to enum_flags. This way we can keep using the safer enum_flags to construct the value, and then be explicit when we need to get at the raw enum. This makes most of the enum_flags operators constexpr. Beyond enabling more compiler optimizations and enabling the new unit tests, this has other advantages, like making it possible to use operator| with enum_flags values in switch cases, where only compile-time constants are allowed: enum_flags<flags> f = FLAG1 | FLAG2; switch (f) { case FLAG1 | FLAG2: break; } Currently that fails to compile. It also switches to a different mechanism of enabling the global operators. The current mechanism isn't namespace friendly, the new one is. It also switches to C++11-style SFINAE -- instead of wrapping the return type in a SFINAE-friently structure, we use an unnamed template parameter. I.e., this: template <typename enum_type, typename = is_enum_flags_enum_type_t<enum_type>> enum_type operator& (enum_type e1, enum_type e2) instead of: template <typename enum_type> typename enum_flags_type<enum_type>::type operator& (enum_type e1, enum_type e2) Note that the static_assert inside operator~() was converted to a couple overloads (signed vs unsigned), because static_assert is too late for SFINAE-based tests, which is important for the CHECK_VALID unit tests.

2020-05-15Add a selftest that detects a 'corrupted' command tree structure in GDB.Philippe Waroquiers1-3/+78
The GDB data structure that records the GDB commands is made of 'struct cmd_list_element' defined in cli-decode.h. A cmd_list_element has various pointers to other cmd_list_element structures, All these pointers are together building a graph of commands. However, when following the 'next' and '*prefixlist' pointers of cmd_list_element, the structure must better be a tree. If such pointers do not form a tree, then some other elements of cmd_list_element cannot get a correct semantic. In particular, the prefixname has no correct meaning if the same prefix command can be reached via 2 different paths. This commit introduces a selftest that detects (at least some cases of) errors leading to 'next' and '*prefixlist' not giving a tree structure. The new 'command_structure_invariants' selftest detects one single case where the command structure is not a tree: (gdb) maintenance selftest command_structure_invariants Running selftest command_structure_invariants. list 0x56362e204b98 duplicated, reachable via prefix 'show ' and 'info set '.

2020-04-23Fix Ada crash with .debug_namesTom Tromey1-3/+3
PR ada/25837 points out a crash in the gdb testsuite when .debug_names is used. You can reproduce like: runtest --target_board=cc-with-debug-names \ gdb.ada/big_packed_array.exp The bug was introduced by commit e0802d599 ("Avoid copying in lookup_name_info"). The problem is that the return type of language_lookup_name changed, but in a way that didn't cause existing callers to trigger a compilation error. Previously, it returned a "const string &", but after it returned a "const char *". This caused a string to be created in dw2_expand_symtabs_matching_symbol, but one that had too short of a lifetime; so eventually the matcher cache would wind up with invalid data. This patch fixes the problem by updating the callers to use the new type. Tested on x86-64 Fedora 30. gdb/ChangeLog 2020-04-23 Tom Tromey <tromey@adacore.com> PR ada/25837: * dwarf2/read.c (dw2_expand_symtabs_matching_symbol): Store a "const char *", not a "const std::string &". <name_and_matcher::operator==>: Update. * unittests/lookup_name_info-selftests.c: Change type of "result".

2019-12-04Compare iterators, not values, in filtered_iterator::operator{==,!=}Simon Marchi1-0/+165
The == and != operators on filtered_iterator are not doing the right thing, they compare values pointed by the wrapped iterators instead of comparing the iterators themselves. As a result, operator== will return true if the two iterators point to two equal values at different positions. operator!= will fail similarly. Also, this causes it to deference past-the-end iterators when doing. For example, in for (iter = ...; iter != end_iter; ++iter) the != comparison dereferences end_iter. I don't think this should happen. I don't think it's a problem today, given that we only use filtered_iterator to wrap linked lists of threads and inferiors. Dereferencing past-the-end iterators of these types is not fatal, it just returns NULL, which is not a value we otherwise find in the lists. But in other contexts, it could become problematic. I have added a simple self test that fails without the fix applied. gdb/ChangeLog: * filtered-iterator.h (filtered_iterator) <operator==, operator!=>: Compare wrapped iterators, not wrapped pointers. * Makefile.in (SUBDIR_UNITTESTS_SRCS): Add unittests/filtered_iterator-selftests.c. * unittests/filtered_iterator-selftests.c: New file.
2019-12-04Fix another build failure in tui-selftests.cTom Tromey1-1/+2
Christian had emailed me to say that the TUI unit test broke the mingw build, but I erroneously thought this was fixed by the earlier patch that made the test body conditional on the TUI being built. However, I was wrong about this -- tui-selftests.c unconditionally includes tui-winsource.h, which fails if curses is not available. This patch fixes the build problem by moving this include into the "#ifdef TUI" section. Tested by rebuilding a mingw-hosted gdb. gdb/ChangeLog 2019-12-04 Tom Tromey <tromey@adacore.com> * unittests/tui-selftests.c: Conditionally include tui-winsource.h.

2019-11-21Handle %I64d in format_piecesTom Tromey1-0/+11
We found a bug internally where gdb would crash while disassembling a certain instruction. This was tracked down to the handling of %I64d in format_pieces. format_pieces will convert %ll to %I64d on mingw -- so format_pieces should also handle parsing this format. In this patch, I've made the parsing unconditional, since I think it is harmless to accept extra formats. I've also taken the opportunity to convert the length modifier test to a "switch". Tested internally using our failing test case. gdb/ChangeLog 2019-11-21 Tom Tromey <tromey@adacore.com> * gdbsupport/format.c (format_pieces): Parse %I64d. * unittests/format_pieces-selftests.c (test_windows_formats): New function.

2019-11-12gdb: Support printf 'z' size modifierAndrew Burgess1-0/+44
The gdb format mechanism doesn't currently support the 'z' size modifier, there are a few places in GDB where this is used. Instead of removing these uses lets just add support to GDB for using 'z'. I found this issue when trying to use some of the debug output. Before this commit: (gdb) set debug dwarf-line 9 (gdb) file test Reading symbols from test... Unrecognized format specifier 'z' in printf (No debugging symbols found in test) (gdb) After this commit: (gdb) set debug dwarf-line 9 (gdb) file test Reading symbols from test...

2019-11-10gdb_vecs.h: Avoid self move assignAndrew Burgess1-0/+66
While working on another patch I ran into an issue with unordered_remove (in gdb_vecs.h), where removing the last item of the vector can cause a self move assign. When compiling the C++ standard library in debug mode (with -D_GLIBCXX_DEBUG=1) this causes an error to trigger. I've fixed the issue in this patch and provided a unit test. The provided unit test includes an assignment operator which checks for self move assign, this removes the need to compile with -D_GLIBCXX_DEBUG=1 in order to spot the bug. If you're keen to see the error reported from the C++ standard library then remove operator= from the unit test and recompile GDB with -D_GLIBCXX_DEBUG=1. gdb/ChangeLog: * Makefile.in (SUBDIR_UNITTESTS_SRCS): Add new file to the list. * unittests/vec-utils-selftests.c: New file. * gdbsupport/gdb_vecs.h (unordered_remove): Avoid self move assign.

2019-10-01Introduce gdb-specific %p format suffixesPedro Alves1-9/+26
This introduces a few gdb-specific %p format suffixes. This is useful for emitting gdb-specific output in an ergonomic way. It also yields code that is more i18n-friendly. The comment before ui_out::message explains the details. Note that the tests had to change a little. When using one of the gdb printf functions with styling, there can be spurious style changes emitted to the output. This did not seem worthwhile to fix, as the low-level output functions are rather spaghetti-ish already, and I didn't want to make them even worse. This change also necessitated adding support for "*" as precision and width in format_pieces. These are used in various spots in gdb, and it seemed better to me to implement them than to remove the uses. gdb/ChangeLog 2019-10-01 Pedro Alves <palves@redhat.com> Tom Tromey <tom@tromey.com> * unittests/format_pieces-selftests.c: Add gdb_format parameter.

Several approaches were discussed (mail or irc) to verify the invariants of the GDB help documentation : checking with apropos ., modifying add_cmd to do the check and output a warning, implement maintenance check-doc. A selftest was finally chosen as: * this can be run on demand, including by users if they want to check user defined commands. * it does not interact with the normal behaviour of apropos, define, python, ... (such as output warnings when a user defines a command help that does not respect the doc). * when the selftest runs, it checks the user defined and python defined commands currently defined. gdb/ChangeLog * unittests/help-doc-selftests.c: New file. * Makefile.in: Add the new file.
2019-07-09Rename common to gdbsupportTom Tromey27-51/+51
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.

2019-06-13Delete parse_flags/parse_flags_qcsPedro Alves1-133/+0
Now that "thread/frame apply" have been converted to the gdb::option framework, these functions are no longer used. For a while, I thought about keeping the unit tests, by making a local version of parse_flags_qcs in the unit tests file. But all that would really test that is used by GDB itself, is the validate_flags_qcs function. So in the end, I went through all the unit tests, and converted any that wasn't already covered to gdb.base/options.exp tests.

2019-05-03On MS-Windows, define _WIN32_WINNT in a single common place.Eli Zaretskii1-4/+0
This changeset defines _WIN32_WINNT to at least 0x0501, the level of Windows XP, unless defined to a higher level, in a single place. It then removes all the overrides of _WIN32_WINNT in individual files as no longer needed. Doing this also solves compilation of windows-nat.c with mingw.org's MinGW, as that file uses CONSOLE_FONT_INFO which needs the XP level to become exposed in the Windows headers, while mingw.org defaults to Windows 9X. gdb/ChangeLog: 2019-05-03 Eli Zaretskii <eliz@gnu.org> * common/common-defs.h [__MINGW32__ || __CYGWIN__]: Define _WIN32_WINNT to the XP level, unless already defined to a higher level. * unittests/parse-connection-spec-selftests.c: * ser-tcp.c: * common/netstuff.c [USE_WIN32API]: Remove the _WIN32_WINNT override. gdb/gdbserver/ChangeLog: 2019-05-03 Eli Zaretskii <eliz@gnu.org> * remote-utils.c: * gdbreplay.c [USE_WIN32API]: Remove the _WIN32_WINNT override.
2019-04-08Rename gdb exception typesTom Tromey2-3/+3
This renames the gdb exception types. The old types were only needed due to the macros in common-exception.h that are now gone.

This changes the exception's "message" member to be a shared_ptr wrapping a std::string. This allows removing the stack of exception messages, because now exceptions will self-destruct when needed.

child_path returns a pointer to the first component in a child path that comes after a parent path.

The function requires that the child path describe a filename that contains at least one component below the parent path and returns a pointer to the first component. gdb/ChangeLog: * Makefile.in (SUBDIR_UNITTESTS_SRCS): Add unittests/child-path-selftests.c. * common/pathstuff.c (child_path): New function. * common/pathstuff.h (child_path): New prototype. * unittests/child-path-selftests.c: New file.

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.

2018-12-21Fix compile error with clang 3.8Dave Murphy1-1/+1
When compiling with clang 3.8 (default clang version on Debian Stretch, the current stable), we get errors like this: CXX dtrace-probe.o ../../binutils-gdb/gdb/dtrace-probe.c:103:31: error: default initialization of an object of const type 'const dtrace_static_probe_ops' without a user-provided default constructor const dtrace_static_probe_ops dtrace_static_probe_ops; ^ Silence them by value-initializing those objects. It's not necessary with other compilers (later clang versions, gcc), but it shouldn't hurt either.
2018-11-21invoke_xmethod & array_viewPedro Alves1-0/+22
This replaces more pointer+length with gdb::array_view. This time, around invoke_xmethod, and then propagating the fallout around, which inevitably leaks to the overload resolution code. There are several places in the code that want to grab a slice of an array, by advancing the array pointer, and decreasing the length pointer. This patch introduces a pair of new gdb::array_view::slice(...) methods to make that convenient and clear. Unit test included. gdb/ChangeLog: 2018-11-21 Pedro Alves <palves@redhat.com> * common/array-view.h (array_view::splice(size_type, size_t)): New.

2018-11-21Use gdb:array_view in call_function_by_hand & friendsPedro Alves1-0/+13
This replaces a few uses of pointer+length with gdb::array_view, in call_function_by_hand and related code. Unfortunately, due to -Wnarrowing, there are places where we can't brace-initialize an gdb::array_view without an ugly-ish cast. To avoid the cast, this patch introduces a gdb::make_array_view function. Unit tests included. This patch in isolation may not look so interesting, due to gdb::make_array_view uses, but I think it's still worth it. Some of the gdb::make_array_view calls disappear down the series, and others could be eliminated with more (non-trivial) gdb::array_view detangling/conversion (e.g. code around eval_call). See this as a "we have to start somewhere" patch. gdb/ChangeLog: 2018-11-21 Pedro Alves <palves@redhat.com> * ada-lang.c (ada_evaluate_subexp): Adjust to pass an array_view. * common/array-view.h (make_array_view): New. * compile/compile-object-run.c (compile_object_run): Adjust to pass an array_view. * elfread.c (elf_gnu_ifunc_resolve_addr): Adjust. * eval.c (eval_call): Adjust to pass an array_view.

2018-11-15Move copy_bitwise unittests to own unittest fileJoel Brobecker1-0/+159
Now that copy_bitwise has been made public, and considering that its implementation could move to a different file again in the future, this patch moves its unittest to its own file in gdb/unittests. gdb/ChangeLog: * unittests/copy_bitwise-selftests.c: New file. * utils.c (selftests::bits_to_str, selftests::check_copy_bitwise) (selftests::copy_bitwise_tests): Delete, moving this code to unittests/copy_bitwise-selftests.c instead. (_initialize_utils): Do not register copy_bitwise tests. * Makefile.in (SUBDIR_UNITTESTS_SRCS): Add unittests/copy_bitwise-selftests.c. Tested on x86_64-linux using the official testsuite, but also by verifying that "maintenance selftests" still runs the copy_bitwise tests.
2018-11-01Import mkdtemp gnulib module, fix mingw buildSimon Marchi1-7/+8
Building with mingw currently fails: CXX unittests/mkdir-recursive-selftests.o /home/emaisin/src/binutils-gdb/gdb/unittests/mkdir-recursive-selftests.c: In function ‘void selftests::mkdir_recursive::test()’: /home/emaisin/src/binutils-gdb/gdb/unittests/mkdir-recursive-selftests.c:49:20: error: ‘mkdtemp’ was not declared in this scope if (mkdtemp (base) == NULL) ^ Commit e418a61a67a ("Move mkdir_recursive to common/filestuff.c") moved this code, but also removed the HAVE_MKDTEMP guard which prevented the mkdtemp call to be compiled on mingw. We can either put back the HAVE_MKDTEMP ifdef, or import the gnulib mkdtemp module, which provides the function for mingw. Since the mkdir_recursive is susceptible to be used on mingw at some point, I think it would be nice to have it tested on mingw, so I did the latter. Once built, I tested it on Windows (copied the resulting gdb.exe on a Windows machine, ran it, and ran "maint selftest mkdir_recursive"). It failed, because the temporary directory is hardcoded to "/tmp/...". I therefore added and used a new get_standard_temp_dir function, which returns an appropriate temporary directory for the host platform. gdb/ChangeLog: * common/pathstuff.c (get_standard_temp_dir): New. * common/pathstuff.h (get_standard_temp_dir): New. * config.in: Re-generate. * configure: Re-generate. * configure.ac: Don't check for mkdtemp. * gnulib/aclocal-m4-deps.mk: Re-generate. * gnulib/aclocal.m4: Re-generate. * gnulib/config.in: Re-generate. * gnulib/configure: Re-generate. * gnulib/import/Makefile.am: Re-generate. * gnulib/import/Makefile.in: Re-generate. * gnulib/import/m4/gnulib-cache.m4: Re-generate. * gnulib/import/m4/gnulib-comp.m4: Re-generate. * gnulib/import/m4/mkdtemp.m4: New file. * gnulib/import/mkdtemp.c: New file. * gnulib/update-gnulib.sh (IMPORTED_GNULIB_MODULES): Add mkdtemp module. * unittests/mkdir-recursive-selftests.c (test): Use get_standard_temp_dir.

2018-10-27Do not reopen temporary filesTom Tromey1-0/+17
The current callers of mkostemp close the file descriptor and then re-open it with fopen. It seemed better to me to continue to use the already-opened file descriptor, so this patch rearranges the code a little in order to do so. It takes care to ensure that the files are only unlinked after the file descriptor in question is closed, as before. gdb/ChangeLog 2018-10-27 Tom Tromey <tom@tromey.com> * unittests/scoped_fd-selftests.c (test_to_file): New function.

2018-10-27Use mkostemp, not mkstempTom Tromey2-3/+5
I noticed that gdb could leak file descriptors coming from mkstemp. This patch fixes the problem by importing the gnulib mkostemp instead, and then changing gdb to pass O_CLOEXEC. A small gnulib patch was needed. This has already been accepted upstream. gdb/ChangeLog 2018-10-27 Tom Tromey <tom@tromey.com> * unittests/scoped_mmap-selftests.c (test_normal): Use gdb_mkostemp_cloexec. * unittests/scoped_fd-selftests.c (test_destroy, test_release): Use gdb_mkostemp_cloexec. * gnulib/aclocal-m4-deps.mk, gnulib/aclocal.m4, gnulib/config.in, gnulib/configure, gnulib/import/Makefile.am, gnulib/import/Makefile.in, gnulib/import/m4/gnulib-cache.m4, gnulib/import/m4/gnulib-comp.m4: Update. * gnulib/import/m4/mkostemp.m4: New file. * gnulib/import/m4/mkstemp.m4: Remove. * gnulib/import/mkostemp.c: New file. * gnulib/import/mkstemp.m4: Remove. * gnulib/update-gnulib.sh (IMPORTED_GNULIB_MODULES): Remove mkstemp, add mkostemp.
