When compiling with -Werror, GNUCash fails to build due to various error: missing sentinel in function call.
This patch resolves the issue by passing nullptr instead of C-style casting NULL.
This requires a std::locale generated from a boost::locale::generator
The examples already in our code base used the wrong message_path while
creating the generator and as a result our message catalogs weren't found.
As with the std::locale I have added code to create a locale via
boost::locale only once instead of having each c++ file redo the work.
This code expects a message_path to set for the boost generator.
An earlier attempt queried for this path directly from within
gnc-locale-utils using gnc_get_locale_dir (from gnc-path.h).
That however broke several c++ tests depending on gnc_locale_utils as those
then also needed to be linked against gnc-path.o. I couldn't get the linker
to do this properly so I worked around it for now by splitting the boost_locale
functionality in two steps:
- an initializer step that takes the messages_path as a string and will
generate the locale
- a getter to get the locale.
The initializer should only be run once, and before the getter is called.
It won't hurt though if the initializer is called more often.
If the getter is called before the initializer it will still
generate a std::locale but without setting a messages_path. It will then
also log a warning explaining translations may not be properly found.
This starts by setting the gnucash version number in the 'project' call.
This will result in a number of variables set by cmake. The remainder
of this commit is to reuse the auto-generated
PROJECT_NAME, PROJECT_VERSION, PROJECT_VERSION_MAJOR
PROJECT_VERSION_MINOR, PROJECT_VERSION_PATCH and PROJECT_VERSION_TWEAK
instead of all the various instances of PACKAGE, GNUCASH_MAJOR_VERSION
and so on.
One parameter is worth mentioning - GETTEXT_PACKAGE
GnuCash is not using this directly (any more) but it has to be set before
including gi18n-lib.h.
On Windows boost::filesystem::path's string() produces a string
that goes out of scope with the function in which it's called, so
returning its c_str() ptr yields freed memory, usually full of garbage.
This has an interesting side effect in gnc-file.c's check_file_path():
Since the memory is freed, g_path_get_dirname() reuses it after an
iteration or two, writing its result into the same address. The
following strcmp naturally returns 0 because it's comparing two
instances of the same ptr, so check_file_path falsely reports that
the proposed save path is in GNC_USERDATA_DIR.
Add function to create an absolute file path from a prefix path and a
relative one. If the prefix is null, then the root directory of the
current path is used.
We can't use std::locale::global because all streams imbue it by
default and if it's not 'C' (aka std::locale::classic) then we
must imbue all the streams that we don't want localized, and that's
most of them.
Provides error checking for setting the C++ locale from the environment.
This is necessary both because the environment might have an invalid
locale, which would cause an unhandled exception crash.
On windows std::locale("") can't handle some Microsoft-style locale
strings (e.g. Spanish_Spain) so we use boost::locale's gen("") function
to set the locale--though even that can't handle a Microsoft-style
locale string with an appended charset (e.g. Spanish_Spain.1252) and
that's what glibc's setlocale(LC_ALL, NULL) emits.
Until now GNC_CONFIG_HOME was more or less hard-coded.
Now it can be set via environment variable GNC_CONFIG_HOME.
In addition it will automatically be created to avoid potential
user confusion.
In a previous commit I wrongly believed xgettext might not find
our strings if we used the fully namespaced boost::locale::translate or
aliased bl::translate instead of just translate. However that's
wrong, so I have changed the code to always use bl::translate.
At present these are
- log.conf
- config-user.scm (previously config.user-2.0)
Implement one-time migration of these files to the proper directory if they previously exist
Look for a log.conf file in gnc_userconfig_dir instead of gnc_userdata_dir
Note this commit also uses boost::locale::translate for the first time.
We may need to fine-tune our use, but in the current state strings marked
for translation using that function are already picked up for gnucash.pot.
Move the CSS settings file to a location based on XDG_CONFIG_HOME which
is OS dependant but with slight changes for Windows and OS X.
- Windows: CSIDL_APPDATA/Gnucash
- OS X: $HOME/Application Support/Gnucash
- Linux: $XDG_CONFIG_HOME/gnucash (or the default $HOME/.config/gnucash)
- Don't attempt to create a subdirectory of a non-existing home directory (use tmpdir as base directory in that case)
- Make sure all tests run in an environment with GNC_BUILDDIR and GNC_UNINSTALLED set. Otherwise
the one-shot old .gnucash to new GNC_DATA_HOME migration may already have run at build time,
preventing us from informing the user a run time.
- Re-enable the userdata-dir with invalid home test (linux only).
It will no longer attempt to use /home/janssege/.gnucash. That was
requiring lots of extra conditions.
It will also default to a base directory (gnc_data_home) in the
build dir if it detects the code is run during building or testing.
That again allows to simplify it as there's no need for temp dir
juggling in case the build environment doesn't have a writable home dir.
Sets paths for finding componenents depending on the state of ENABLE_BINRELOC,
GNC_UNINSTALLED, GNC_BUILDDIR and whether any install paths have been set
outside of CMAKE_INSTALL_PREFIX.
GNUInstallDirs changes the name of CMAKE_INSTALL_LIBDIR depending on the
operating system and distro. When CMAKE_INSTALL_PREFIX is /usr,
/usr/local, or any subdirectory of /opt it also changes
CMAKE_INSTALL_FULL_SYSCONFDIR to /etc. An earlier commit by Aaron Laws
mirrors the name of CMAKE_INSTALL_LIBDIR to the build library directory.
It's possible for builders to set any of the install directories
anywhere they please.
Setting any directory outside of CMAKE_INSTALL_PREFIX breaks Binreloc so
the toplevel CMakeLists.txt now detects that and disables Binreloc.
If Binreloc is enabled then all path queries use it to find paths. This
works in the build directory because the gnucash executable and all of
the test programs are in build_directory/bin and LIBDIR, DATADIR, and
SYSCONFDIR can be found in the same root path.
If Binreloc is disabled then in order to build or run programs from the
build directory one must set GNC_UNINSTALLED and set GNC_BUILDDIR to the
absolute path of the build directory. When those are set GNC_BUILDDIR
replaces CMAKE_INSTALL_PREFIX in all paths that are subdirectories of
CMAKE_INSTALL_PREFIX; paths that are not in CMAKE_INSTALL_PREFIX are
appended whole to GNC_BUILDDIR. This process is constent between CMake
and gnc_path_get_foo. GnuCash is unlikely to run from a DESTDIR without
Binreloc.
This will avoid a ninja-build from picking up a config.h generated by the autotools build
(in the root build directory). Picking up the wrong config.h may lead to all kinds of
subtle issues if the autotools run was done with different options than the cmake run.
userdata_home is a different directory on each platform we support (default /home/janssege/.local/share on linux for example)
and gnc_userdata_home is normally userdata_home/GnuCash.
These directories may not always exist (yet) in all circumstances, so properly handle
all of these possible situations.
- have gnc_validate_directory throw as well in case of a missing directory
that it shouldn't create. This allows to remove 3 other throws
- slightly adjust the error message in case of missing directory
- never migrate when the final directory is a temporary (sub)directory
The utf8 conversion is only used in the Windows specific section so there's no
need to define an overloaded function on std::string in this case.
Also CMakeLists.txt doesn't require the MingW specific library name setting
for boost::filesystem. Just removing the hardcoded one allows the build to
pick the right name up from the Boost_LIBRARIES variable.
- Linux: use whatever the xdg spec dictates
- Windows: use AppData(Roaming)
- OS X/Quarz: use NSApplicationSupportDirectory special directory, which
typically resolves to $HOME/Library/Application Support
If the preferred directory can't be used the code will fallback to
$HOME/.gnucash (the old location) if it exists. It won't create it
however. Instead if missing it will fall back to the platform's
temporary directory.
Code is added also to automatically migrate all data from the old
location to the new (only the first time).
