The lack of such exporting seems to cause problems catching
exceptions, as suggested by
http://gcc.gnu.org/wiki/Visibility
This manifested in the symbol-hiding test failing when notmuch was
compile with gcc 4.4.5. On i386, this further manifested as notmuch
new failing to run (crashing with an uncaught exception on first run).
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.

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 $^

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.
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. We also use vpath directives to convince GNU make
to find the source files from the original source directory.
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.
This increment is for the recently-added functions:
notmuch_query_get_query_string
notmuch_query_get_sort
These were recently added to the library interface, but the library
version was not incremented at that time, (shame on me).
Hi,
If I want to build Debian package, it fails with the following message:
ldconfig: Can't create temporary cache file /etc/ld.so.cache~: Permission denied
make[1]: *** [install-lib] Error 1
The reason is that I build the package as a non-root user and make
install invokes ldconfig unconditionally. The following patch contains a
workaround, but I think that a more correct solution would be to check
the condition LIBDIR_IN_LDCONFIG directly when make install is invoked
rather than in configure as it is done now.

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).
This encodes the library version into the library, where the linking
binary can pick it up, and the linker can even enforce mismatches in
the minor release, (such as linking a binary against version 1.2 and
then attempting to run it against version 1.1).
I'm not sure which system Aaron used, but on the machine I have access
to, (Darwin 8.11.0), the -shared and -dylib_install_name options are
not recognized. Instead I use -dynamic_lib and -install_name as
documented here:
http://www.finkproject.org/doc/porting/shared.php
This patch adds a configure check for OS X (actually Darwin),
and sets up the Makefiles to build a proper shared library on
that platform.

With the original quiet function, there's an actual purpose (hiding
excessively long compiler command lines so that warnings and errors
from the compiler can be seen).
But with things like quiet_symlink there's nothing quieter. In fact
"SYMLINK" is longer than "ln -sf". So all this is doing is hiding the
actual command from the user for no real benefit.
The only actual reason we implemented the quiet_* functions was to be
able to neatly right-align the command name and left-align the arguments.
Let's give up on that, and just left-align everything, simplifying the
Makefiles considerably. Now, the only instances of a captialized command
name in the output is if there's some actually shortening of the command
itself.
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.
The idea here is to allow a new user of notmuch to be able to run
notmuch immediately after compiling, (without having to install
the shared library first). This also ensures that the test suite
tests the locally compiled library, and not whatever installled
version of the library the dynamic linker happens to find.
When I wanted to create a debian package from the current master, make
install failed because of non-existent include directory. This patch
fixes this minor issue.
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).
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.
This new directory ojbect provides all the infrastructure needed to
detect when files or directories are deleted or renamed. There's still
code needed on top of this (within "notmuch new") to actually do that
detection.
Use the facilities of GNU make to create a magic function that will
on the first invocation print a description of how to enable verbose
compile lines and then print the quiet rule.

[ickle: Rebased, and duplicate command string eliminated.]

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.
Previously, the top-level Makefile was explicitly adding -I./lib to
the compiler flags. However, that's something that's much better done
from within the Makefile.local fragment within the lib directory
itself.
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).
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.
