libgpg-error/src/gpg-error.vers, branch gniibe/t5912

New public function gpgrt_access.

2020-10-19T13:21:59Z

* src/gpg-error.h.in (gpgrt_access): New. * src/gpg-error.vers. src/gpg-error.def.in: Add new function. * src/sysutils.c (any8bitchar): New. (_gpgrt_access): New. * src/visibility.c (gpgrt_access): New. * src/spawn-w32.c (_gpgrt_spawn_process_detached): Use it. * src/argparse.c (try_versioned_conffile): Use it. * tests/t-stringutils.c (check_access): New simple test. -- This is basically a wrapper to allow handling of utf8 encoded file names on Windows. This also fixes the case for versioned config files in directories with non-ascii characters. The new test needs to be run manually on Windows using a directory with Unicode characters. GnuPG-bug-id: 5098

estream: Add gpgrt_fcancel

2020-06-26T13:25:27Z

* src/estream.c (do_close): Add arg 'cancel_mode' and chnage all callers. (_gpgrt_fcancel): New. * src/gpg-error.def.in, src/gpg-error.vers: Add function. * src/visibility.c (gpgrt_fcancel): New. * src/gpg-error.h.in (gpgrt_fcancel): New. -- Signed-off-by: Werner Koch

core: New function gpgrt_reallocarray.

2020-03-03T14:41:39Z

* src/init.c (_gpgrt_reallocarray): New. * src/visibility.c (gpgrt_reallocarray): New. * src/gpg-error.vers, src/gpg-error.def.in: Add new function. * src/gpg-error.h.in: Add new interface. * tests/t-malloc.c: New. * tests/Makefile.am (TESTS): Add new test. -- Note that this function is different from the glibc function because it has an extra parameter which allows to clear the new elements. A realloc after a calloc with forgotten memset after it is a common source of error, thus we introduce this slightly different function. Signed-off-by: Werner Koch

core: Add a high level option/argument parser.

2020-02-18T15:50:46Z

* gpg-error.h.in (GPGRT_CONFDIR_USER, GPGRT_CONFDIR_SYS): New consts. (ARGPARSE_FLAG_SYS, ARGPARSE_FLAG_USER, ARGPARSE_FLAG_VERBOSE) (ARGPARSE_NO_CONFFILE, ARGPARSE_CONFFILE, ARGPARSE_OPT_CONFFILE): New consts. (ARGPARSE_conffile, ARGPARSE_noconffile): New macros. (gpgrt_set_confdir): New func. (gpgrt_argparser): New func. * src/argparse.c (confdir): New var. (enum argparser_states): New. (struct _gpgrt_argparse_internal_s): Add a couple of new fields. (initialize): Init them. (any_opt_conffile): New. (_gpgrt_argparser): New. (_gpgrt_set_confdir): New. * src/visibility.c (gpgrt_argparser): New. (gpgrt_set_confdir): New. * src/gpg-error.def.in, src/gpg-error.vers: Add those functions. * tests/t-argparse.c (main): Reworked. * tests/etc/t-argparse.conf: New file. * tests/t-argparse.conf: New file. -- gpgrt_argparser is a high level version of gpgrt_argparse. It handles reading of configuration files internally and allows allows for a global configuration file. The design is so that it minimizes the work to replace the existing option parsing in gpg and friends by this one and to allow global configuration files for them. This is the just the basic code which should allow replacement of the parsers. A forthcoming patch will implement flags for options given in the global config file.

core: Add gpgrt_fnameconcat and gpgrt_absfnameconcat.

2020-02-18T07:56:33Z

* src/gpg-error.h.in (gpgrt_fnameconcat): New. (gpgrt_absfnameconcat): New. * src/visibility.c (gpgrt_fnameconcat, gpgrt_absfnameconcat): New. * src/stringutils.c: New file. (_gpgrt_vfnameconcat): New. (_gpgrt_fnameconcat, _gpgrt_absfnameconcat): New. * src/gpg-error.def.in: Add new functions. * src/gpg-error.vers: Ditto. * src/sysutils.c: Include pwd.h. (_gpgrt_getpwdir): New. * configure.ac: Test for pwd.h, getpwnam, getpwuid, and their _r variants. * src/Makefile.am (libgpg_error_la_SOURCES): Add new file. * tests/t-stringutils.c: New. * tests/t-common.h (xmalloc, xstrdup, xfree): New. (die): Kludge to avoid compiler warnings. -- The new functions are based on the code of make_filename from GnuPG. They have been written by me ages ago with only minor modifications by David Shaw. I re-license them from LGPL-3.0+ OR GPL-2.0+ to LGPL-2.1-or-later. Signed-off-by: Werner Koch

core: New functions gpgrt_abort and gpgrt_add_emergency_cleanup.

2019-01-04T12:13:53Z

* src/init.c (emergency_cleanup_list): New gloabl var. (_gpgrt_add_emergency_cleanup): New. (_gpgrt_abort): New. Repalce all calls to abort by this. Also replace all assert by either log_assert or a stderr output followed by a _gpgrt_abort. (run_emergency_cleanup): New. * src/visibility.c (gpgrt_add_emergency_cleanup): New public API. (gpgrt_abort): New public API. -- Libgcrypt uses its own assert function which makes sure to terminate the secure memory. This is safe as log as an assert is triggered internally in Libgcrypt. GnuPG runs emergency cleanup handlers right before log_fatal etc to tell Libgcrypt to terminate the secure memory. With the move of the logging function to gpgrt in gnupg 2.3 this did not anymore. Thus we now provide a mechanism in gpgrt to do right that. Eventually Libgcrypt can also make use of this. What this does not handle are calls to abort or failed asserts in external libraries or in libc. We can't do anything about it in a library because a library may not setup signal handlers.

core: New functions gpgrt_fprintf_sf anf gpgrt_fprintf_sf_unlocked.

2018-11-26T19:22:24Z

* src/gpg-error.h.in (gpgrt_string_filter_t): New type. (gpgrt_fprintf_sf, gpgrt_fprintf_sf_unlocked): New. * src/gpg-error.vers, src/gpg-error.def.in: Add them. * src/visibility.c (gpgrt_fprintf_sf): New. (gpgrt_fprintf_sf_unlocked): New. * src/estream-printf.c (pr_string): Add and use args sf, sfvalue and string_no. (do_format): Add args sf and sfvalue. Keep a string format counter. (_gpgrt_estream_format): Add args sf and sfvalue. Change all callers to provide NULL for them. * src/estream.c (_gpgrt_vfprintf_unlocked, _gpgrt_vfprintf): Add sf and sfvalue and adjust all callers. (do_print_stream): Ditto. * tests/t-printf.c (stream_to_string): New. (struct sfstate_s): New. (string_filter): New. (check_fprintf_sf): New. (main): Call new test. -- The actual reason to implement these functions is to enhance the internal logging function with a filter to sanitized strings so that control values or other things can be quoted.

core: Add a limited version of gpgrt_ftruncate.

2018-11-26T19:09:53Z

* src/gpg-error.h.in (gpgrt_ftruncate, es_ftruncate): New. * src/gpg-error.def.in, src/gpg-error.vers: Add gpgrt_ftruncate. * src/visibility.c (gpgrt_ftruncate): new. * src/gpgrt-int.h (COOKIE_IOCTL_TRUNCATE): New. * src/estream.c (func_mem_ioctl): Support new internal IOCTL. (_gpgrt_ftruncate): New. -- Right now the ftruncate works only on memory streams. Can easily be added to other stream times. Signed-off-by: Werner Koch

core: New API gpgrt_cmp_version

2018-11-15T18:28:20Z

* src/gpg-error.h.in: New API gpgrt_cmp_version. * src/visibility.c (gpgrt_cmp_version): New wrapper. * src/version.c (parse_version_string): Revamped. (do_cmp_version): New. (_gpgrt_cmp_version): New. (_gpg_error_check_version): Re-implemented using the new func. * tests/t-version.c: Include t-common.h. (t_gpgrt_cmp_version): New test. (main): Run new test. Change test for new version number to require a 2 level number. -- We have implementations of very similar functions in all out libs. Thus it makes sense to provide a generic version. This version is actually derived from the ftp-indexer.c we use for the gnupg website (see the gnupg-doc repo). Signed-off-by: Werner Koch

core: Add Base-64 encoder.

2018-03-22T16:38:24Z

* src/b64enc.c: Change to fit into libgpg-error. * src/Makefile.am: Add b64enc.c * src/b64dec.c: Use xtrymalloc etc. Always use gpg_err_code_t. (_gpgrt_b64dec_start): Set decoder flag (_gpgrt_b64dec_finish): Check for conflict. (_gpgrt_b64state): Move to ... * src/gpgrt-int.h: here.
