Makefile.local: Automatically use makefile mode We add a magic line to the beginning of each Makefile.local file to help the editor know that it should use makefile mode for editing the file, (even though the filename isn't exactly "Makefile"). Edited-by: Carl Worth <cworth@cworth.org>: Expand treatment from emacs/Makefile.local to each instance of Makefile.local.

libnotmuch: add linker script to declare only notmuch_* symbols as global. This is closely tied to gcc and particularly gnu ld, but I guess the shared library linking code would need to be adjusted to work on a non-gnu linker anyay. I had to make a few not-obviously related changes to the lib/Makefile.local to make this work: libnotmuch_modules is defined with := and used in place of $^ (cherry picked from commit 014bf85b1c06ff49be2bde5a26433d2cf376cf70)

make install: Run ldconfig or install a DT_RUNPATH in binary as appropriate. Various users were confused as to why they couldn't run notmuch immediately after "make install", (with linker errors saying that libnotmuch.so could not be found). The errors came from two different causes: 1. The user had installed to a system library directory, but had not yet run ldconfig. 2. The user had installed to some non-system directory, and had not set the LD_LIBRARY_PATH variable. With this change we fix both problems (on Linux) without the user having to do anything additional. We first use ldconfig to find the system library directories. If the user is installing to one of these, then we run ldconfig as part of "make install". For case (2) we use the -rpath and --enable-new-dtags linker options to install a DT_RUNPATH entry in the binary. This entry tells the dynamic linker where to find libnotmuch. Without the --enable-new-dtags option only a DT_RPATH option would be installed, (which has the drawback of not allowing any override with the LD_LIBRARY_PATH variable). Distributions (such as Debian and Fedora) don't want to see binaries packaged with a DT_RPATH or DT_RUNPATH entry. This should be avoided automatically as long as the packages install to standard locations, (such as /usr/lib).

Move installation of library from top-level to lib/Makefile.local We had a fairly ugly violation of modularity with the top-level Makefile.local isntalling everything, (even when the build commands for the library were down in lib/Makefile.local).

Makefile: Fix Makefiles to depend on all child Makefile fragments. We were previously maintaining two lists of the child Makefile fragments---one for the includes and another for the dependencies. So, of course, they drifted and the dependency list wasn't up to date. We fix this by adding a single subdirs variable, and then using GNU Makefile substitution to generate both the include and the dependency lists. Some side effect of this change caused the '=' assignment of the dir variable to not work anymore. I'm not sure why that is, but using ':=' makes sense here and fixes the problem.

build: Add support for non-source-directory builds. Such as: mkdir build cd build ../configure make This is implemented by having the configure script set a srcdir variable in Makefile.config, and then sprinkling $(srcdir) into various make rules.

Implement a non-recursive make. The idea here is that every Makefile at each lower level will be an identical, tiny file that simply defers to a top-level make. Meanwhile, the Makefile.local file at each level is a Makefile snippet to be included at the top-level into a large, flat Makefile. As such, it needs to define its rules with the entire relative directory to each file, (typically in $(dir)). The local files can also append to variables such as SRCS and CLEAN for files to be analyzed for dependencies and to be cleaned.

Makefile: Fix dependency generation to make .d files themselves dependent. I saw this recommendation in the implementation notes for "Recursive Make Considered Harmful" and then the further recommendation for implementing the idea in the GNU make manual. The idea is that if any of the files change then we need to regenerate the dependency file before we regenerate any targets. The approach from the GNU make manual is simpler in that it just uses a sed script to fix up the output of an extra invocation of the compiler, (as opposed to the approach in the implementation notes from the paper's author which use a wrapper script for the compiler that's always invoked rather than the compiler itself).

lib: Add new implementation of notmuch_filenames_t The new implementation is simply a talloc-based list of strings. The former support (a list of database terms with a common prefix) is implemented by simply pre-iterating over the terms and populating the list. This should provide no performance disadvantage as callers of thigns like notmuch_directory_get_child_files are very likely to always iterate over all filenames anyway. This new implementation of notmuch_filenames_t is in preparation for adding API to query all of the filenames for a single message.

Implement an internal generic string list and use it. This replaces the guts of the filename list and tag list, making those interfaces simple iterators over the generic string list. The directory, message filename, and tags-related code now build generic string lists and then wraps them in specific iterators. The real wins come in later patches, when we use these for even more generic functionality. As a nice side-effect, this also eliminates the annoying dependency on GList in the tag list.

lib: Move notmuch_messages_t code from query.cc to new messages.c The new object is simply a linked-list of notmuch_message_t objects, (unlike the old object which contained a couple of Xapian iterators). This works now by the query code immediately iterator over all results and creating notmuch_message_t objects for them, (rather than waiting to create the objects until the notmuch_messages_get call as we did earlier). The point of this change is to allow other instances of lists of messages, (such as in notmuch_thread_t), that are not directly related to Xapian search results.

libnotmuch: fix typos in CLEAN setting, add file - c0961e6 introduced a missing slash between $(dir)$(LIBNAME) and missing $(dir) in front of libnotmuch.a - cdf1c70a created a file $(dir)/notmuch.h.gch and neglected to add it to CLEAN

libnotmuch: build symbols list without relying on gcc -aux-info. Carl reports "gcc -aux-info notmuch.aux lib/notmuch.h" does not generate notmuch.aux for him with Debian gcc 4.6.0-8. A small modification of the original sed regular expression allows us to work directly from lib/notmuch.h, rather than preprocessing with gcc. As with most such simple regex based "parsing", this is quite sensitive to the input format, and needs that each symbol to be exported from libnotmuch should - start with "notmuch_" - be the first non-whitespace token on the line - be followed by an open parenthesis.
