A "username" in jw-pkg terms, as in $(CLONE_FROM_USER), is not sufficient to identify a remote API URL on a Forgejo server, it can denote both an organization and a user, so try organizations first, then users, and stop on the first occasion found.
Retire pkg-manager.sh and replace it by the cleaner "jw-pkg.sh distro" command, essentially providing the same functionality and nearly the same command-line interface.
400 LOC more. That's what the move from a shell script to the more maintainable Python versions costs. Still a good idea, and the enhanced extensibility might pay off in terms of LOC with other shell scripts in the future.
Add a hand-coded __init__.py into jw.pkg.cmds.distro. Auto-generation works fine, but has to run before it can work. For a freshly downloaded toplevel Makefile / project-dirs-minimal.mk, the targets pkg-install-xxx-deps requires a working package manager without jw-pkg built.
Cmd._run(), as conceived for working with lib.App, is meant to be an async method. To be conservative about changes, jw-pkg's legacy way of handling _run() was kept when deriving from libApp, and async was not propagated down to the _run() implementations. This commit rectifies that before adding additional subcommands.
During __init__(), commands have no idea of their parent. This is not a problem as of now, but is easy to fix, and it's architecturally desirable to be prepared just in case, so add the parent argument to the ctor before more commands are added.
As per info make, it turns out that ifndef SOME_VAR is true for SOME_VAR defined to an empty value. This is unusable for caching, so replace it with ifeq ($(origin SOME_VAR),undefined).
ResultCache is a home-grown result cache. The @lru_cache decorator, now available in Python 3, accomplishes the same thing, so try to ditch ResultCache for it.
Sadly, this doesn't entirely work as of now, because it uses hash() to hash the arguments, which won't work for the two list-type arguments to add_modules_from_project_txt() (buf and visited).
App.res_cache should be private. It's needed here to cache the results of a function which is private to CmdBuild anyway, so solve that with lru_cache, to allow App to do it's private thing with caching.
Add support for --topdir-format. The option supports several different values, affecting the console output of App wherever it knows that the output contains a reference to the projects' toplevel directory.
- "unaltered" will have it print the toplevel directory in the same
format as passed to the commandline
- "absolute" will try to resolve it to an absolute path before
printing
- make:XXX will return the make-varible $(XXX) instead
To implement this, the proj_dir() member function is turned into the private member function __proj_dir(), and a new member function find_dir() is supplied, with two additional parameters: search_subdirs and search_absdirs, which will try to find an existing directory relative to the toplevel directory of the given module, or in the search_absdirs list, respectively.
Command modules in cmds.projects have been updated to use the new function.
Reorganize the Python module structure. Placing the command classes under jw.cmds.projects instead of jw.build.cmds will allow to add a nested command structure, with the current commands, being mostly related to building software, found below a "projects" toplevel command.
Other conceivable commands could be "package" for packaging, or "distro" for commands wrapping the distribution's package manager.
Make App.proj_dir() return an absolute path. This looks like a good idea, because some of the $(call proj_query xxx) paths end up being relative, because they get proj_dir()'s idea of a directory prepended. This prohibits caching them in $(TOPDIR)/make/.cache.mk for make benefit glorious nation of performance.
Derive jw.pkg.App from jw.pkg.lib.App. App.run() dissolves as follows:
- Its sub-command invocation logic is left to the base class - parser.add_arguments() are moved into self._add_arguments() - So is handling of early-parsed arguments - async def _run() is reimplemented to set some member variables
Add App and Cmd as generic base classes for multi-command applications. The code is taken from jw-python: The exising jw.pkg.App is very similar to the more capable jwutils.Cmds class, so, to avoid code duplication, add it here to allow for jwutils.Cmds and jw.pkg.App to derive from it at some point in the future.
Both had to be slightly modified to work within jw-pkg's less equipped context, and will need futher code cleanup.
Types is a container for types, notably classes, which are dynamically loaded from other modules. Which modules are loaded is based on the following criteria passed to its constructor:
- mod_names: A list of modules to load and investigate
- type_name_filter: A regular filter expression or None (default).
If it's None, all types pass this filter.
- type_filter: A list of types the returned types must match.
Defaults to [], in which case all types pass this filter
A dedicated logging module is currently provided by jw-python, but since it's often needed also in jw-pkg, and it's relatively small and maintainable, it seems justified to move it into jw-pkg.
CmdGetval.add_arguments() uses self.app.top_name, which may or may not be initialized at the time this runs. Not using it makes CmdGetval's ctor safe to run in the context of App.__init__().
Remove PY_PREREQ_BUILD and PY_PREREQ_BUILD_DIRS from py-defs.mk: Apparently they're not used anywhere, and are costly in terms of directory startup time.
This commit aims at improving speed by using better caching.
- Makefile, cache.mk: Split .cache.mk up
To allow caching of runtime path variables which are
project-specific, split .cache.mk up in .cache-project.mk and
.cache-projects.mk
- ldlibpath.mk: Cache ldlibpath, exepath and pythonpath
Place the output of $(call proj_query ldlibpath), $(call
proj_query, exepath) and $(call proj_query pythonpath) in
JW_PKG_LD_LIBRARY_PATH, JW_PKG_EXE_PATH, and JW_PKG_PYTHON_PATH
respectively, and cache the variables in make/.project-cache.mk.
- cache.mk: Use = instead of :=
Recursively expanded variables are nearly as fast as := variables
if the assigned value is a fixed string. And sometimes it's not,
rightly so, because variables get assigned below, as with
JW_PKG_XXX for instance.
- cache.mk: Use $(TOPDIR) as variable values
Replace absolute references to project's topdir by $(TOPDIR) with
sed. As soon as the project queries produce absolute paths, they
will be transformed into relative paths which allow the code base
to be moved to a different location and still remain functional
without a rebuild.
Remove unused code, and code which actually does something: CACHED_VARS looks as if it's sufficently and more centrally defined in make.mk, don't override that.
Add std-targets.mk, meant to be included mostly to make sure all mandatory targets are there. On clean and distclean, it also removes stuff that should not be there anymore after clean.
