2019-08-07Add a selftest that checks documentation invariants.Philippe Waroquiers1-0/+107
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. 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. *

2019-06-13Delete 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. And those have all already been added in previous patches. gdb/ChangeLog: 2019-06-13 Pedro Alves <palves@redhat.com> * cli/cli-utils.c (parse_flags, parse_flags_qcs): Delete. * cli/cli-utils.h (parse_flags, parse_flags_qcs): Delete. * unittests/cli-utils-selftests.c (test_parse_flags) (test_parse_flags_qcs): Delete. (test_cli_utils): Don't call deleted functions.
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. The intermediate layer of gdb_exception_RETURN_MASK_ALL did not seem needed, so this patch removes it entirely. gdb/ChangeLog 2019-04-08 Tom Tromey <tom@tromey.com> * common/common-exceptions.h (gdb_exception_RETURN_MASK_ALL): Remove.

2019-04-08Make exceptions use std::string and be self-managingTom Tromey1-2/+2
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.

CXXLD gdb ld: init.o: in function `initialize_all_files()': init.c:(.text+0x113): undefined reference to `_initialize_string_view_selftests()' It happens because '_initialize_string_view_selftests()' is conditionally defined based on C++ default.

child_path returns a pointer to the first component in a child path that comes after a parent path. This does not depend on trying to stat() the paths since they may describe remote paths but instead relies on filename parsing. 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.

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).

(_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.

2018-10-04Simple -Wshadow=local fixesTom Tromey1-4/+4
This fixes all the straightforward -Wshadow=local warnings in gdb. A few standard approaches are used here: * Renaming an inner (or outer, but more commonly inner) variable; * Lowering a declaration to avoid a clash; * Moving a declaration into a more inner scope to avoid a clash, including the special case of moving a declaration into a loop header. I did not consider any of the changes in this patch to be particularly noteworthy, though of course they should all still be examined. gdb/ChangeLog 2018-10-04 Tom Tromey <tom@tromey.com> * ctf.c (SET_ARRAY_FIELD): Rename "u32". * p-valprint.c (pascal_val_print): Split inner "i" variable. * xtensa-tdep.c (xtensa_push_dummy_call): Declare "i" in loop header. * xstormy16-tdep.c (xstormy16_push_dummy_call): Declare "val" in more inner scope. * xcoffread.c (read_xcoff_symtab): Rename inner "symbol". * varobj.c (varobj_update): Rename inner "newobj", "type_changed". * valprint.c (generic_emit_char): Rename inner "buf". * valops.c (find_overload_match): Rename inner "temp".

2018-10-01Don't check HAVE_UNISTD_HTom Tromey2-10/+3
I noticed some spots that were checking HAVE_UNISTD_H. There is no need to do this, as <unistd.h> is unconditionally included in many places in gdb.

2018-08-07Introduce mmap_file functionSimon Marchi1-0/+54
New in v2: - As Tom pointed out, we don't need to keep the fd around after mmapping. This simplifies things quite a bit, since we don't need a new class. It's now just a function that returns a scoped_mmap. We already have scoped_mmap, which is a thin RAII layer over mmap. If one simply wants to mmap an entire file for reading, it takes a bit of boilerplate. This patch introduces the mmap_file function to make this easier. gdb/ChangeLog: * Makefile.in (COMMON_SFILES): Add common/scoped_mmap.c. * common/scoped_mmap.c: New file. * common/scoped_mmap.h (destroy): New method.

2018-07-11Implement IPv6 support for GDB/gdbserverSergio Durigan Junior1-0/+249
This patch implements IPv6 support for both GDB and gdbserver. Based on my research, it is the fourth attempt to do that since 2006. Since I used ideas from all of the previous patches, I also added their authors's names on the ChangeLogs as a way to recognize their efforts. For reference sake, you can find the previous attempts at: https://sourceware.org/ml/gdb-patches/2006-09/msg00192.html https://sourceware.org/ml/gdb-patches/2014-02/msg00248.html https://sourceware.org/ml/gdb-patches/2016-02/msg00226.html The basic idea behind the patch is to start using the new 'getaddrinfo'/'getnameinfo' calls, which are responsible for translating names and addresses in a protocol-independent way. This means that if we ever have a new version of the IP protocol, we won't need to change the code again (or, at least, won't have to change the majority of the code). The function 'getaddrinfo' returns a linked list of possible addresses to connect to. Dealing with multiple addresses proved to be a hard task with the current TCP auto-retry mechanism implemented on ser-tcp:net_open. For example, when gdbserver listened only on an IPv4 socket: $ ./gdbserver --once 127.0.0.1:1234 ./a.out and GDB was instructed to try to connect to both IPv6 and IPv4 sockets: $ ./gdb -ex 'target extended-remote localhost:1234' ./a.out the user would notice a somewhat big delay before GDB was able to connect to the IPv4 socket. This happened because GDB was trying to connect to the IPv6 socket first, and had to wait until the connection timed out before it tried to connect to the IPv4 socket. For that reason, I had to rewrite the main loop and implement a new method for handling multiple connections. After some discussion, Pedro and I agreed on the following algorithm: 1) For each entry returned by 'getaddrinfo', we try to open a socket and connect to it. 2.a) If we have a successful 'connect', we just use that connection. 2.b) If we don't have a successfull 'connect', but if we've got a ECONNREFUSED (meaning the the connection was refused), we keep track of this fact by using a flag. 2.c) If we don't have a successfull 'connect', but if we've got a EINPROGRESS (meaning that the connection is in progress), we perform a 'select' call on the socket until we have a result (either a successful connection, or an error on the socket). 3) If tcp_auto_retry is true, and we haven't gotten a successful connection, and at least one of our attempts failed with ECONNREFUSED, then we wait a little bit (i.e., call 'wait_for_connect'), check to see if there was a timeout/interruption (in which case we bail out), and then go back to (1). After multiple tests, I was able to connect without delay on the scenario described above, and was also able to connect in all other types of scenarios. I also implemented some hostname parsing functions (along with their corresponding unit tests) which are used to help GDB and gdbserver to parse hostname strings provided by the user. These new functions are living inside common/netstuff.[ch]. I've had to do that since IPv6 introduces a new URL scheme, which defines that square brackets can be used to enclose the host part and differentiate it from the port (e.g., "[::1]:1234" means "host ::1, port 1234"). I spent some time thinking about a reasonable way to interpret what the user wants, and I came up with the following: - If the user has provided a prefix that doesn't specify the protocol version (i.e., "tcp:" or "udp:"), or if the user has not provided any prefix, don't make any assumptions (i.e., assume AF_UNSPEC when dealing with 'getaddrinfo') *unless* the host starts with "[" (in which case, assume it's an IPv6 host). - If the user has provided a prefix that does specify the protocol version (i.e., "tcp4:", "tcp6:", "udp4:" or "udp6:"), then respect that. This method doesn't follow strictly what RFC 2732 proposes (that literal IPv6 addresses should be provided enclosed in "[" and "]") because IPv6 addresses still can be provided without square brackets in our case, but since we have prefixes to specify protocol versions I think this is not an issue. Another thing worth mentioning is the new 'GDB_TEST_SOCKETHOST' testcase parameter, which makes it possible to specify the hostname (without the port) to be used when testing GDB and gdbserver. For example, to run IPv6 tests: $ make check-gdb RUNTESTFLAGS='GDB_TEST_SOCKETHOST=tcp6:[::1]' Or, to run IPv4 tests: $ make check-gdb RUNTESTFLAGS='GDB_TEST_SOCKETHOST=tcp4:127.0.0.1' This required a few changes on the gdbserver-base.exp, and also a minimal adjustment on gdb.server/run-without-local-binary.exp. Finally, I've implemented a new testcase, gdb.server/server-connect.exp, which is supposed to run on the native host and perform various "smoke tests" using different connection methods. This patch has been regression-tested on BuildBot and locally, and also built using a x86_64-w64-mingw32 GCC, and no problems were found. gdb/ChangeLog: 2018-07-11 Sergio Durigan Junior <sergiodj@redhat.com> Jan Kratochvil <jan.kratochvil@redhat.com> Paul Fertser <fercerpav@gmail.com> Tsutomu Seki <sekiriki@gmail.com> Pedro Alves <palves@redhat.com> * Makefile.in (SUBDIR_UNITTESTS_SRCS): Add 'unittests/parse-connection-spec-selftests.c'.

2018-05-17Make format_pieces recognize the \e escape sequenceSimon Marchi1-0/+76
I noticed that the printf command did not recognize the \e escape sequence, used amongst other things to use colors: (gdb) printf "This is \e[32mgreen\e[m!\n" Unrecognized escape character \e in format string. This patch makes format_pieces recognize it, which makes that command print the expected result in glorious color. I wrote a really simple unit test for format_pieces. format_pieces::operator[] is unused so I removed it.

When building with x86_64-w64-mingw32-g++ (to test cross-compiling for Windows), I get this error: unittests/string_view-selftests.o: In function `selftests::string_view::inserters_2::test05(unsigned long long)': /home/emaisin/src/binutils-gdb/gdb/unittests/basic_string_view/inserters/char/2.cc:60: undefined reference to `std::basic_ofstream<char, std::char_traits<char> >::rpl_close()' This is caused by gnulib redefining "close" as "rpl_close", and therefore messing up the declaration of basic_ofstream in the libstdc++ header. The solution would be to use gnulib namespaces [1]. Until we use them across GDB, we can use them locally in files that are problematic, like this one. gdb/ChangeLog: * unittests/string_view-selftests.c: Define GNULIB_NAMESPACE.
2018-04-09Adapt and integrate string_view testsSimon Marchi25-152/+375
The previous patch copied the string_view tests from libstdc++. This patch adjusts them in a similar way that the libstdc++ optional tests are integrated in our unit test suite. Not all tests are used, some of them require language features not present in c++11. For example, we can't use a string_view constructor where the length is not explicit in a constexpr, because std::char_traits::length is not a constexpr itself (it is in c++17 though). Nevertheless, a good number of tests are integrated, which covers pretty well the string_view features. gdb/ChangeLog: * Makefile.in (SUBDIR_UNITTESTS_SRCS): Add string_view-selftests.c. * unittests/basic_string_view/capacity/1.cc: Adapt to GDB testsuite. * unittests/basic_string_view/cons/char/1.cc: Likewise. * unittests/basic_string_view/cons/char/2.cc: Likewise. * unittests/basic_string_view/cons/char/3.cc: Likewise. * unittests/basic_string_view/element_access/char/1.cc: Likewise. * unittests/basic_string_view/element_access/char/empty.cc: Likewise. * unittests/basic_string_view/element_access/char/front_back.cc: Likewise. * unittests/basic_string_view/inserters/char/2.cc: Likewise. * unittests/basic_string_view/modifiers/remove_prefix/char/1.cc: Likewise. * unittests/basic_string_view/modifiers/remove_suffix/char/1.cc: Likewise. * unittests/basic_string_view/modifiers/swap/char/1.cc: Likewise. * unittests/basic_string_view/operations/compare/char/1.cc: Likewise. * unittests/basic_string_view/operations/compare/char/13650.cc: Likewise. * unittests/basic_string_view/operations/copy/char/1.cc: Likewise. * unittests/basic_string_view/operations/data/char/1.cc: Likewise. * unittests/basic_string_view/operations/find/char/1.cc: Likewise. * unittests/basic_string_view/operations/find/char/2.cc: Likewise. * unittests/basic_string_view/operations/find/char/3.cc: Likewise. * unittests/basic_string_view/operations/find/char/4.cc: Likewise. * unittests/basic_string_view/operations/rfind/char/1.cc: Likewise. * unittests/basic_string_view/operations/rfind/char/2.cc: Likewise. * unittests/basic_string_view/operations/rfind/char/3.cc: Likewise. * unittests/basic_string_view/operations/substr/char/1.cc: Likewise. * unittests/basic_string_view/operators/char/2.cc: Likewise. * unittests/string_view-selftests.c: New file.

2018-03-22Make parse_static_tracepoint_marker_definition work with multiple static ↵Simon Marchi1-0/+70
tracepoint definitions Since I modify the parse_static_tracepoint_marker_definition function in the next patch, I wanted to write a unit test for it. Doing so showed that it doesn't handle multiple consecutive static tracepoint definitions separated by commas. However, the RSP documentation [1] states that servers may return multiple definitions, like: 1234:6d61726b657231:6578747261207374756666,abba:6d61726b657232: The problem is that the function uses strlen to compute the length of the last field (the extra field). If there are additional definitions in addition to the one we are currently parsing, the returned length will include those definitions, and we'll try to hex-decode past the extra field. This patch changes parse_static_tracepoint_marker_definition to consider the case where the current definition is followed by a comma and more definitions. It also adds the unit test that found the issue in the first place. I don't think this causes any backwards compatibility issues, because the previous code only handled single static tracepoint definitions, and the new code handles that correctly. gdb/ChangeLog: * tracepoint.c (parse_static_tracepoint_marker_definition): Consider case where the definition is followed by more definitions. * Makefile.in (SUBDIR_UNITTESTS_SRCS): Add tracepoint-selftests.c. * unittests/tracepoint-selftests.c: New.

2018-03-19Convert observers to C++Tom Tromey1-0/+135
This converts observers from using a special source-generating script to be plain C++. This version of the patch takes advantage of C++11 by using std::function and variadic templates; incorporates Pedro's patches; and renames the header file to "observable.h" (this change eliminates the need for a clean rebuild). Note that Pedro's patches used a template lambda in tui-hooks.c, but this failed to compile on some buildbot instances (presumably due to differing C++ versions); I replaced this with an ordinary template function.

[This patch should go on top of "linux_qxfer_libraries_svr4: Use std::string", I should have sent them together as a series.] I noticed that linux_qxfer_libraries_svr4 used xml_escape_text, which returns an std::string. That string is then copied into a larger buffer. It would be more efficient if we had a version of xml_escape_text which appended to an existing string instead of returning a new one. This is what this patch does. I manually verified that the output of linux_qxfer_libraries_svr4 didn't change before/after the patch. gdb/ChangeLog: * common/xml-utils.c (xml_escape_text): Move code to...

2018-02-26Sign-extend non-bit-fields in unpack_bits_as_longTom Tromey1-0/+61
unpack_bits_as_long is documented as sign-extending its result when the type is signed. However, it was only doing sign-extension in the case where the field was a bitfield -- that is, not when the "bitsize" parameter was 0, indicating the size should be taken from the type. Also, unpack_bits_as_long was incorrectly computing the shift for big-endian architectures for the non-bitfield case. This patch fixes these bugs in a straightforward way. A new selftest is included. 2018-02-26 Tom Tromey <tom@tromey.com> * Makefile.in (SUBDIR_UNITTESTS_SRCS): Add unittests/unpack-selftests.c. * unittests/unpack-selftests.c: New file. * value.c (unpack_bits_as_long): Fix bugs in non-bitfield cases.

2017-11-24remote: C++ify thread_item and threads_listing_contextSimon Marchi1-0/+59
This patch C++ifies the thread_item and threads_listing_context structures in remote.c. thread_item::{extra,name} are changed to std::string. As a result, there's a bit of awkwardness in remote_update_thread_list, where we have to xstrdup those strings when filling the private_thread_info structure. This is removed in the following patch, where private_thread_info is also C++ified and its corresponding fields made std::string too. The xstrdup then becomes an std::move. Other than that there's nothing really special, it's a usual day-to-day VEC -> vector and char* -> std::string change. It allows removing a cleanup in remote_update_thread_list. Note that an overload of hex2bin that returns a gdb::byte_vector is added, with corresponding selftests. gdb/ChangeLog: * remote.c (struct thread_item): Add constructor, disable copy construction and copy assignment, define default move construction and move assignment. <extra, name>: Change type to std::string. <core>: Initialize. <thread_handle>: Make non-pointer.

2017-11-08lookup_name_info::make_ignore_paramsPedro Alves1-0/+111
A few places in the completion code look for a "(" to find a function's parameter list, in order to strip it, because psymtabs (and gdb index) don't include parameter info in the symbol names. See compare_symbol_name and default_collect_symbol_completion_matches_break_on. This is too naive. Consider: ns_overload2_test::([TAB] We'd want to complete that to: ns_overload2_test::(anonymous namespace)::struct_overload2_test Or: b (anonymous namespace)::[TAB] That currently completes to: b (anonymous namespace) Which is obviously broken. This patch makes that work. Also, the current compare_symbol_name hack means that while this works: "b function([TAB]" -> "b function()" This does not: "b function ([TAB]" This patch fixes that. Whitespace "ignoring" now Just Works, i.e., assuming a symbol named "function(int, long)", this: b function ( int , lon[TAB] completes to: b function ( int , long) To address all of this, this patch builds on top of the rest of the series, and pushes the responsibility of stripping parameters from a lookup name to the new lookup_name_info object, where we can apply per-language rules. Also note that we now only make a version of the lookup name with parameters stripped out where it's actually required to do that, in the psymtab and GDB index code. For C++, the right way to strip parameters is with "cp_remove_params", which uses a real parser (cp-name-parser.y) to split the name into a component tree and then discards parameters. The trouble for completion is that in that case we have an incomplete name, like "foo::func(int" and thus cp_remove_params throws an error. This patch sorts that by adding a cp_remove_params_if_any variant of cp_remove_params that tries removing characters from the end of the string until cp_remove_params works. So cp_remove_params_if_any behaves like this: With a complete name: "foo::func(int)" => foo::func(int) # cp_remove_params_1 succeeds the first time. With an incomplete name: "foo::func(int" => NULL # cp_remove_params fails the first time. "foo::func(in" => NULL # and again... "foo::func(i" => NULL # and again... "foo::func(" => NULL # and again... "foo::func" => "foo::func" # success! Note that even if this approach removes significant rightmost characters, it's still OK, because this parameter stripping is only necessary for psymtabs and gdb index, where we're determining whether to expand a symbol table. Say cp_remove_params_if_any returned "foo::" above for "foo::func(int". That'd cause us to expand more symtabs than ideal (because we'd expand all symtabs with symbols that start with "foo::", not just "foo::func"), but then when we actually look for completion matches, we'd still use the original lookup name, with parameter information ["foo::func(int"], and thus we'll return no false positive to the user. Whether the stripping works as intended and doesn't strip too much is thus covered by a unit test instead of a testsuite test. The "if_any" part of the name refers to the fact that while cp_remove_params returns NULL if the input name has no parameters in the first place, like: "foo::func" => NULL # cp_remove_params cp_remove_params_if_any still returns the function name: "foo::func" => "foo::func" # cp_remove_params_if_any gdb/ChangeLog: 2017-11-08 Pedro Alves <palves@redhat.com> * Makefile.in (SUBDIR_UNITTESTS_SRCS): Add unittests/lookup_name_info-selftests.c.

2017-10-30Introduce string_appendf/string_vappendfPedro Alves1-0/+49
string_appendf is like string_printf, but instead of allocating a new string, it appends to an existing string. This allows reusing a std::string's memory buffer across several calls, for example. gdb/ChangeLog: 2017-10-30 Pedro Alves <palves@redhat.com> * common/common-utils.c (string_appendf, string_vappendf): New functions. * common/common-utils.h (string_appendf, string_vappendf): New declarations. * unittests/common-utils-selftests.c (string_appendf_func) (test_appendf_func, string_vappendf_wrapper, string_appendf_tests) (string_vappendf_tests): New functions. (_initialize_common_utils_selftests): Register "string_appendf" and "string_vappendf tests".
2017-10-30Merge/shared string_printf and string_vprintf unit testsPedro Alves1-15/+29
Merge the string_printf and string_vprintf tests, running them all against both functions. gdb/ChangeLog: 2017-10-30 Pedro Alves <palves@redhat.com> * unittests/common-utils-selftests.c (format_func): New typedef. (string_printf_tests, string_vprintf_tests): Tests factored out and merged to ... (test_format_func): ... this new function. (string_printf_tests, string_vprintf_tests): Reimplement on top of test_format_func.
