* [vcstocl] Import ProjectQuirks from its own fileSiddhesh Poyarekar2020-08-201-1/+1
| | | | | | ProjectQuirks moved into its own file in gnulib because one cannot import modules with hyphens in them. Adjust the quirks file to reflect this reality.
* build-many-glibcs.py: Add a s390x -O3 glibc variant.Stefan Liebler2020-08-201-2/+11
| | | | | | | | | | | | | | | On s390x, gcc inlines more aggresive compared to other architectures. This occaisionally leads to build warnings / errors. Therefore this patch adds a s390x glibc variant with optimization. There is the ccopts field which contain ABI options which are passed to configure as CC / CXX. Now there is also the cflags field which contains non-ABI options like -g or -O. Those are passed to configure as CFLAGS / CXXFLAGS. Currently CC is passed to conformtest.py or linknamespace.py but not the CFLAGS.
* Use MPC 1.2.0 in build-many-glibcs.py.Joseph Myers2020-08-191-1/+1
| | | | | | | This patch makes build-many-glibcs.py use the new MPC 1.2.0 release. Tested with build-many-glibcs.py (host-libraries, compilers and glibcs builds).
* Update build-many-glibcs.py for binutils ia64 obsoletion.Joseph Myers2020-08-131-3/+9
| | | | | | | | | | | | Since binutils has obsoleted ia64 support, use --enable-obsolete for now when configuring binutils for ia64 in build-many-glibcs.py (which requires adding support for architecture-specific binutils configure options there). As with other obsoletions, the removal of support for ia64 in any of (binutils, GCC, Linux kernel) should imply its removal from glibc. Tested with build-many-glibcs.py for ia64-linux-gnu (compilers and glibcs build).
* Use Linux 5.8 in build-many-glibcs.py.Joseph Myers2020-08-071-1/+1

* Remove --enable-obsolete-rpc configure flagPetr Vorel2020-07-131-6/+0
| | | | | | | | | | | | | | | | | | | | | | Sun RPC was removed from glibc. This includes rpcgen program, librpcsvc, and Sun RPC headers. Also test for bug #20790 was removed (test for rpcgen). Backward compatibility for old programs is kept only for architectures and ABIs that have been added in or before version 2.28. libtirpc is mature enough, librpcsvc and rpcgen are provided in rpcsvc-proto project. NOTE: libnsl code depends on Sun RPC (installed libnsl headers use installed Sun RPC headers), thus --enable-obsolete-rpc was a dependency for --enable-obsolete-nsl (removed in a previous commit). The arc ABI list file has to be updated because the port was added with the sunrpc symbols Tested-by: Carlos O'Donell <carlos@redhat.com> Reviewed-by: Carlos O'Donell <carlos@redhat.com>

* Remove --enable-obsolete-nsl configure flagPetr Vorel2020-07-081-4/+2
| | | | | | | | | | | | | | | | | | | this means that *always* libnsl is only built as shared library for backward compatibility and the NSS modules libnss_nis and libnss_nisplus are not built at all, libnsl's headers aren't installed. This compatibility is kept only for architectures and ABIs that have been added in or before version 2.28. Replacement implementations based on TIRPC, which additionally support IPv6, are available from <https://github.com/thkukuk/>. This change does not affect libnss_compat which does not depended on libnsl since 2.27 and thus can be used without NIS. libnsl code depends on Sun RPC, e.g. on --enable-obsolete-rpc (installed libnsl headers use installed Sun RPC headers), which will be removed in the following commit.
* signal: Move sys_errlist to a compat symbolAdhemerval Zanella2020-07-071-2/+1
| | | | | | | | | | | | | | | | | | | | The symbol is deprecated by strerror since its usage imposes some issues such as copy relocations. Its internal name is also changed to _sys_errlist_internal to avoid static linking usage. The compat code is also refactored by removing the over enginered errlist-compat.c generation from manual entried and extra comment token in linker script file. It disantangle the code generation from manual and simplify both Linux and Hurd compat code. The definitions from errlist.c are moved to errlist.h and a new test is added to avoid a new errno entry without an associated one in manual. Checked on x86_64-linux-gnu and i686-linux-gnu. I also run a check-abi on all affected platforms. Tested-by: Carlos O'Donell <carlos@redhat.com> Reviewed-by: Carlos O'Donell <carlos@redhat.com>

* Linux: Remove <sys/sysctl.h> and the sysctl functionFlorian Weimer2020-04-151-5/+0
| | | | | | | | | | | | | | | Linux 5.5 remove the system call in commit 61a47c1ad3a4dc6882f01ebdc88138ac62d0df03 ("Linux: Remove <sys/sysctl.h>"). Therefore, the compat function is just a stub that sets ENOSYS. Due to SHLIB_COMPAT, new ports will not add the sysctl function anymore automatically. x32 already lacks the sysctl function, so an empty sysctl.c file is used to suppress it. Otherwise, a new compat symbol would be added. Reviewed-by: Adhemerval Zanella <adhemerval.zanella@linaro.org>

| | | | | | | | The history is not used by build-many-glibcs.py itself. --replace-sources deletes an existing source tree before switching the version. But some users prefer to have the full history available, therefore make shallow clones optional with the --shallow option.

* Use --disable-gdbserver in build-many-glibcs.py.Joseph Myers2020-02-101-0/+1
| | | | | | | | | | | | | Now that binutils-gdb has gdbserver at top level, an extra --disable-gdbserver configure option is needed when configuring binutils from a git checkout to avoid it also building gdbserver unnecessarily (although fairly harmlessly). This patch updates the options used in build-many-glibcs.py accordingly (although this might end up not being needed depending on what happens regarding whether gdbserver gets built for host != target). Tested with a build-many-glibcs.py compilers build for aarch64-linux-gnu using binutils-gdb master.

* gitlog-to-changelog: Drop scripts in favour of gnulib versionSiddhesh Poyarekar2020-01-235-1181/+0
| | | | | | | | | | | | | The ChangeLog automation scripts were incorporated in gnulib as vcs-to-changelog for a while now since other projects expressed the desire to use and extend this script. In the interest of avoiding duplication of code, drop the glibc version of gitlog-to-changelog and use the gnulib one directly. The only file that remains is vcstocl_quirks.py, which specifies properties and quirks of the glibc project source code. This patch also drops the shebang at the start of vcstocl_quirks.py since the file is not intended to be directly executable.

| | | | | | | | | | | | | | | I've updated copyright dates in glibc for 2020. This is the patch for the changes not generated by scripts/update-copyrights and subsequent build / regeneration of generated files. As well as the usual annual updates, mainly dates in --version output (minus libc.texinfo which previously had to be handled manually but is now successfully updated by update-copyrights), there is a fix to sysdeps/unix/sysv/linux/powerpc/bits/termios-c_lflag.h where a typo in the copyright notice meant it failed to be updated automatically. Please remember to include 2020 in the dates for any new files added in future (which means updating any existing uncommitted patches you have that add new files to use the new copyright dates in them).

* Script to generate ChangeLog-like output from git logSiddhesh Poyarekar2019-09-205-0/+1244

Gomes <gabriel@inconstante.net.br> Reviewed-by: Gabriel F. T. Gomes <gabriel@inconstante.net.br> Reviewed-by: Joseph Myers <joseph@codesourcery.com> The utility of a ChangeLog file has been discussed in various mailing list threads and GNU Tools Cauldrons in the past years and the general consensus is that while the file may have been very useful in the past when revision control did not exist or was not as powerful as it is today, it's current utility is fast diminishing. Further, the ChangeLog format gets in the way of modernisation of processes since it almost always results in rewriting of a commit, thus preventing use of any code review tools to automatically manage patches in the glibc project. There is consensus in the glibc community that documentation of why a change was done (i.e. a detailed description in a git commit) is more useful than what changed (i.e. a ChangeLog entry) since the latter can be deduced from the patch. The GNU community would however like to keep the option of ascertaining what changed through a ChangeLog-like output and as a compromise, it was proposed that a script be developed that generates this output. The script below is the result of these discussions. This script takes two git revisions references as input and generates the git log between those revisions in a form that resembles a ChangeLog. Its capabilities and limitations are listed in a comment in the script. On a high level it is capable of parsing C code and telling what changed at the top level, but not within constructs such as functions. Design ------ At a high level, the script analyses the raw output of a VCS, parses the source files that have changed and attempts to determine what changed. The script driver needs three distinct components to be fully functional for a repository: - A vcstocl_quirks.py file that helps it parse weird patterns in sources that may result from preprocessor defines. - A VCS plugin backend; the git backend is implemented for glibc - A programming language parser plugin. C is currently implemented. Additional programming language parsers can be added to give more detailed output for changes in those types of files. For input in languages other than those that have a parser, the script only identifies if a file has been added, removed, modified, permissions changed, etc. but cannot understand the change in content. The C Parser ------------ The C parser is capable of parsing C programs with preprocessor macros in place, as if they were part of the language. This presents some challenges with parsing code that expands macros on the fly and to help work around that, a vcstocl_quirks.py file has transformations to ease things. The C parser currently can identify macro definitions and scopes and all global and static declarations and definitions. It cannot parse (and compare) changes inside functions yet, it could be a future enhancement if the need for it arises. Testing ------- The script has been tested with the glibc repository up to glibc-2.29 and also in the past with emacs. While it would be ideal to have something like this in a repository like gnulib, that should not be a bottleneck for glibc to start using this, so this patch proposes to add these scripts into glibc. And here is (hopefully!) one of the last ChangeLog entries we'd have to write for glibc: * scripts/gitlog_to_changelog.py: New script to auto-generate ChangeLog. * scripts/vcs_to_changelog/frontend_c.py: New file. * scripts/vcs_to_changelog/misc_util.py: New file. * scripts/vcs_to_changelog/vcs_git.py: New file. * scripts/vcs_to_changelog/vcstocl_quirks.py: Likewise.
