This (obvious) bug was caused by cut&pasting the code from
notmuch-config.c into the library and adding on a return at the end.
|
|
When compat canonicalize_file_name was introduced, it was limited to
C code only because it was used by C code only during that time.
>From 5ec6fd4d, (lib/open: check for split configuration when creating
database., 2021-02-16), lib/open.cc, which is C++, relies on the
existent of canonicalize_file_name.
However, we can't blindly enable canonicalize_file_name for C++ code,
because different implementation has different additional signature for
C++ and users can arbitrarily add -DHAVE_CANONICALIZE_FILE_NAME=0 to
{C,CXX}FLAGS.
Let's move our implementation into a util library.

Ignoring this return value seems like a bad idea in general, and in
particular it has been hiding one or more bugs related to handling
long directory names.

This is intended to fix the slow behaviour of "notmuch new" (and possibly
"notmuch reindex") when large numbers of files are deleted.
The underlying issue [1] seems to be the Xapian glass backend spending
a large amount of time in db.has_positions when running queries with
large-ish amounts of unflushed changes.
This commit removes two uses of Xapian queries [2], and replaces them with
an approximation of what Xapian would do after optimizing the
queries. This avoids the calls to has_positions (which are in any case
un-needed because we are only using boolean terms here).
[1] Thanks to "andres" on IRC for narrowing down the performance
bottleneck.
[2] Thanks to Olly Betts of Xapian fame for talking me a through a fix
that does not require people to update Xapian.

Since the library searches in several locations for a config file, the
caller does not know which of these is chosen in the usual case of
passing NULL as a config file. This changes provides an API for the
caller to retrieve the name of the config file chosen. It will be
tested in a following commit.
|
|
Eventually we want to do all opening of databases in the top
level (main function). This means that detection of missing databases
needs to move out of subcommands. It also requires updating the
library to use the new NO_DATABASE status code.
|
|
This will allow more precise return values from various open related functions.
|
|
notmuch_config_open will be preserved in the medium term for use by
the commands that are manipulating the config file directly (config
and setup)
|
|
This matches functionality in the the CLI function
notmuch_config_get_database_path, which was previously used in the CLI
code for all calls to open a database.
|
|
This is mainly copying code from the CLI into the lib. The CLI copy
will be deleted in a later commit.
|
|
This just copies code from from the CLI into the library. New test
infrastructure is needed because apparently we have never tested this
code path.
|
|
The layer of shims here seems a bit wasteful compared to just calling
the corresponding string map functions directly, but it allows control
over the API (calling with notmuch_database_t *) and flexibility for
future changes.
|
|
This is to support the less common (at least in the notmuch codebase)
case of accessing a ;-delimited list config value with an arbitrary
string key.
|
|
This is mainly targetted at notmuch-config.c, or similar applications
that don't necessarily need both a configuration file and a database
to exist.
|
|
Although this increases code duplication, it also increases
flexibility in handling various combinations of missing config file
and missing database.
|
|
|
|
_trial_open can't know if the PATH_ERROR return value will cause the
error message to be returned from the library, so it's up the caller
to clean up if not.
|
|
Like the hook directory, we primarily need a way to communicate this
directory between various components, but we may as well let the user
configure it.
Most of the diff is generalizing choose_hook_dir to work for both
backup and hook directories.
|
|
Choose sibling directory of xapian database, as .notmuch may not
exist.
libgen.h is already used in debugger.c, so it is not a new dependency
/ potential portability problem.
|
|
This promotes _choose_xapian_path from static to extern linkage in
order to share between open.cc and database.cc.
|
|
This changes some error reporting, either intentionally by reporting
the highest level missing directory, or by side effect from looking in
XDG locations when given null database location.
|
|
The main functionality will be tested when notmuch-new is converted to
support split configuration. Here only the somewhat odd case of split
mail root which is actually symlinked to the database path is tested.
|
|
Introduce a new configuration value for the mail root, and use it to
locate mail messages in preference to the database.path (which
previously implied the mail messages were also in this location.
Initially only a subset of the CLI is tested in a split
configuration. Further changes will be needed for the remainder of the
CLI to work in split configurations.
|
|
This is a bit heavyweight for now, but it will make more sense when we
check multiple locations for the Xapian database.
|
|
This avoids reading the configuration file twice.
|
|
The idea is to allow reuse in n_d_create_with_config. This is
primarily code movement, with some changes in error messages to reduce
the number of input parameters.
|
|
Make checks more uniform between creating new databases and opening
existing ones.
|
|
This is slightly more tidy, but more importantly it allows for re-use
of this code in n_d_create_with_config. That re-use will be crucial
when we no longer call n_d_open_with_config from
n_d_create_with_config.
|
|
This removes duplication between the struct element and the
configuration string_map entry. Create a simple wrapper for setting
the database path that makes sure the trailing / is stripped.
|
|
This gives more flexibility in restructuring the database opening
code.
|
|
The additional code is trivial, but making sure we get the priority of
various options correct takes a few tests.
|
|
In the future Xapian will apparently support this more conveniently
for the cases other than READ_ONLY => READ_ONLY
Conceptually this function seems to fit better in lib/open.cc;
database.cc is still large enough that moving the function makes
sense.
|
|
This will allow re-opening in a different mode (read/write
vs. read-only) with current Xapian API. It will also prove useful when
updating the compact functions to support more flexible database
location.
|
|
Include the (currently unused) mode argument which will specify which
mode to re-open the database in. Functionality and docs to be
finalized in a followup commit.
|
|
This fixes a small-to-medium (depending on size of config file) memory
leak.
|
|
This fixes a few small memory leaks.
|
|
This fixes a small memory leak.
|
|
This better matches the memory allocation semantics in
notmuch_database_open_with_config.
|
|
This is the result of running
$ uncrustify --replace --config ../devel/uncrustify.cfg *.c *.h *.cc
in the lib directory

notmuch 0.31.4 release
|

Based on a patch from Michael J Gruber [1]. As of glib 2.67 (more
specifically [2]), including "gmime-extra.h" inside an extern "C"
block causes build failures, because glib is using C++ features.
Observing that "gmime-extra.h" is no longer needed in
notmuch-private.h, which can simply delete that include, but
we have to correspondingly move the includes which might include
it (in particular crypto.h) out of the extern "C" block also.
This seems less fragile than only moving gmime-extra, and relying on
preprocessor sentinels to keep the deeper includes from happening.
Move to the include to the outside of the extern block.

This would have caught bugs like the one corrected in the previous commit.
|
|
With the current unused macro in lib/notmuch-private.h this seems
harmless, but is misleading, since the parameter is in fact used.
|
|
Many public status values have been added without being copied to the
list of private status values.
|
|
This is a simple two step path search. Most error checking is
deferred until running the hooks.
|
|
The hook directory configuration needs to be kept in synch with the
other configuration information, so add scaffolding to support this at
database opening time.
|
|
This takes a config path parameter, and can use that to decide the
new database location.
|
|
It is desirable to distinguish between attempting to create a database
that already exists, and more fatal errors like permission problems.
|
|
This will help share code with n_d_open_with_config.
|
|
This will allow client code to provide more meaningful diagnostics. In
particular it will enable "notmuch new" to continue suggsting the user
run "notmuch setup" to create a config after "notmuch new" is
transitioned to the new configuration framework.
