* Split notmuch_database_close into two functionsJustus Winter2012-04-28
| | | | | | | | | | | | | | | | | | Formerly notmuch_database_close closed the xapian database and destroyed the talloc structure associated with the notmuch database object. Split notmuch_database_close into notmuch_database_close and notmuch_database_destroy. This makes it possible for long running programs to close the xapian database and thus release the lock associated with it without destroying the data structures obtained from it. This also makes the api more consistent since every other data structure has a destructor function. The comments in notmuch.h are a courtesy of Austin Clements.

* lib: work around talloc_steal usage from C++ codeJani Nikula2012-04-15
| | | | | | | | | | | | | | | | Implicit typecast from 'void *' to 'T *' is okay in C, but not in C++. In talloc_steal, an explicit cast is provided for type safety in some GCC versions. Otherwise, a cast is required. Provide a template function for this to maintain type safety, and redefine talloc_steal to use it. The template must be outside the extern "C" block (NOTMUCH_BEGIN_DECLS and NOTMUCH_END_DECLS), but keep it within the GCC visibility #pragma. No functional changes, apart from making the library build with compilers other than recent GCC. Signed-off-by: Jani Nikula <jani@nikula.org>

* lib: fix an exclude bugMark Walters2012-03-18
| | | | | | | | | | When the exclude tags contain a tag that does not occur anywhere in the Xapian database the exclusion fails. We modify the way the query is constructed to `work around' this. (In fact the new code is cleaner anyway.) It also seems to fix another exclusion failure bug reported by jrollins but we have not yet worked out why it helps in that case.

* lib: Expose query debug output via an environment variableAustin Clements2012-03-18
| | | | | | | | | Allow query debugging to be enabled at run-time by setting the NOTMUCH_DEBUG_QUERY environment variable to a non-empty string. Previously, enabling query debugging required recompiling, but parsed queries are often useful for tracking down bugs in situations where recompiling is inconvenient.

| | | | | | | | | | | | | | | | | | Formerly it was possible for *message_ret to be left uninitialized. The documentation however clearly states that "[o]n any failure or when the message is not found, this function initializes '*message' to NULL".

| * Actually close the xapian database in notmuch_database_closeJustus Winter2012-03-03
| | | | | | | | | | | | | | | | | | | | | | Formerly the xapian database object was deleted and closed in its destructor once the object was garbage collected. Explicitly call close() so that the database and the associated lock is released immediately. The comment is a courtesy of Austin Clements.

* | lib: Add the exclude flag to notmuch_query_search_threadsMark Walters2012-03-02
| | | | | | | | | | | | | | | | | | | | | | Add the NOTMUCH_MESSAGE_FLAG_EXCLUDED flag to notmuch_query_search_threads. Implemented by inspecting the tags directly in _notmuch_thread_create/_thread_add_message rather than as a Xapian query for speed reasons. Note notmuch_thread_get_matched_messages now returns the number of non-excluded matching messages. This API is not totally desirable but fixing it means breaking binary compatibility so we delay that.
* | lib: Make notmuch_query_search_messages set the exclude flagMark Walters2012-03-02
| | | | | | | | | | | | | | | | | | | | Add a flag NOTMUCH_MESSAGE_FLAG_EXCLUDED which is set by notmuch_query_search_messages for excluded messages. Also add an option omit_excluded_messages to the search that we do not want the excludes at all. This exclude flag will be added to notmuch_query_search threads in the next patch.
* | lib: Rearrange the exclude code in query.ccMark Walters2012-03-02
|/ | | | | Slightly refactor the exclude code to give the callers access to the exclude query itself. There should be no functional change.
* Convert non-UTF-8 parts to UTF-8 before indexing themMichal Sojka2012-02-29
| | | | | | | This fixes a bug that didn't allow to search for non-ASCII words such parts. The code here was copied from show_text_part_content(), because the show command already does the needed conversion when showing the message.
* Prevent segmentation fault in notmuch_database_closeJustus Winter2012-02-20
| | | | | | | | | | | | Previously opening a notmuch database in read write mode that has been locked resulted in the notmuch_database_open function executing notmuch_database_close as a cleanup function. notmuch_database_close failed to check whether the xapian database has in fact been created. Add a check whether the xapian database object has actually been created before trying to call its flush method. Signed-off-by: Justus Winter <4winter@informatik.uni-hamburg.de>
* lib: Use talloc to simplify cleanup in notmuch_database_openAustin Clements2012-02-03
| | | | | | | Previously, we manually "free"d various pointers in notmuch_database_open. Use a local talloc context instead to simplify cleanup and eliminate various NULL pointer initializations and conditionals.
* lib: Release resources if notmuch_database_open failsAustin Clements2012-02-03
| | | | | Previously, if a Xapian exception occurred in notmuch_database_open, we failed to clean up the allocated notmuch_database_t object.
* lib: Don't delete uninitialized pointersAustin Clements2012-02-03
| | | | | | | | | In the error-handling paths of notmuch_database_open, we call notmuch_database_close, which "delete"s several objects referenced by the notmuch_database_t object. However, some of these pointers may be uninitialized, resulting in undefined behavior. Hence, allocate the notmuch_database_t with talloc_zero to make sure these pointers are NULL so that "delete"ing them is harmless.
* lib: Add support for automatically excluding tags from queriesAustin Clements2012-01-16
| | | | | | This is useful for tags like "deleted" and "spam" that people generally want to exclude from query results. These exclusions will be overridden if a tag is explicitly mentioned in a query.

* lib: call g_mime_init() from notmuch_database_open()Kazuo Teramoto2011-12-31
| | | | | | | | | | | | | | As reported in id:"CAEbOPGyuHnz4BPtDutnTPUHcP3eYcRCRkXhYoJR43RUMw671+g@mail.gmail.com" sometimes gmime tries to access a NULL pointer, e.g. g_mime_iconv_open() tries to access iconv_cache that is NULL if g_mime_init() is not called. This causes notmuch to segfault when calling gmime functions. Calling g_mime_init() initializes iconv_cache and others variables needed by gmime, making sure they are initialized when notmuch calls gmime functions. Test marked fix by db.
* Ignore encrypted parts when indexing.Jameson Graef Rollins2011-12-29
| | | | | | | | It appears to be an oversight that encrypted parts were indexed previously. The terms generated from encrypted parts are meaningless and do nothing but add bloat to the database. It is not worth indexing the encrypted content, just as it's not worth indexing the signatures in signed parts.
* Fix comments about what is stored in the databaseThomas Jost2011-12-23
| | | | | | Commit 567bcbc2 introduced two new values for each message (content of the "From" and "Subject" headers), but the comments about the database schema had not been updated accordingly.
* notmuch: Quiet buildbot warnings.David Edmondson2011-12-21
| | | | | Cast away the result of various *write functions. Provide a default value for some variables to avoid "use before set" warnings.

* | Don't link libnotmuch if libutil isn't linked in properly.Tom Prince2011-11-19
|/ | | | | | | For some reason, on my machine, the link is picking up /usr/lib/libutil.so instead of util/libutil.a. This causes there to be undefined symbols in libnotmuch, making it unuseable. This patch causes the link to fail instead.
* lib: add function to get the number of threads matching a searchJani Nikula2011-11-15
| | | | | | | | | Add function notmuch_query_count_threads() to get the number of threads matching a search. This is done by performing a search and figuring out the number of unique thread IDs in the matching messages, a significantly heavier operation than notmuch_query_count_messages().

* Store "from" and "subject" headers in the database.Austin Clements2011-11-14
| | | | | | | | | | | | | | This is a rebase and cleanup of Istvan Marko's patch from id:m3pqnj2j7a.fsf@zsu.kismala.com Search retrieves these headers for every message in the search results. Previously, this required opening and parsing every message file. Storing them directly in the database significantly reduces IO and computation, speeding up search by between 50% and 10X. Taking full advantage of this requires a database rebuild, but it will fall back to the old behavior for messages that do not have headers stored in the database.
* Link libutil using filenmae, rather than using -l.Tom Prince2011-11-13
| | | | | glibc includes a libutil, so if the wrong -L options get passed, we will pick up glibc's version, rather than our own.
* lib/database.cc: use flush Xapian method instead of commitDavid Bremner2011-11-02
| | | | | | | Apparently the method was renamed in Xapian 1.1.0 but the old method name will stay around for a while. It seems better to stick with the old name to make notmuch compile with older versions of Xapian, at least for now.
* xutil.c: remove duplicate copies, create new library libutil.a to contain xutil.David Bremner2011-10-30
| | | | | | | We keep the lib/xutil.c version. As a consequence, also factor out _internal_error and associated macros. It might be overkill to make a new file error_util.c for this, but _internal_error does not really belong in database.cc.
* Prefix lib/notmuch.h and lib/gen-version-script.sh with $(srcdir)Amadeusz Żołnowski2011-10-24
| | | | | lib/notmuch.h and lib/gen-version-script.sh couldn't have been found when building out of sources directory.
* lib: bump SONAMEDavid Bremner2011-10-04
| | | | | | | | | | | Based on discussions with amdragon, tschwinge, and others on IRC, I concluded that 1) symbol versioning was probably overkill for libnotmuch 2) It was also probably GNU ld specific 3) Most importantly, nobody could tell me on short notice how exactly it works. So since the change to the notmuch_database_find_message breaks the previous ABI, we need to bump the SONAME.
* lib: make find_message{,by_filename) report errorsAli Polatel2011-10-04
| | | | | | | | | | | | | | | | Previously, the functions notmuch_database_find_message() and notmuch_database_find_message_by_filename() functions did not properly report error condition to the library user. For more information, read the thread on the notmuch mailing list starting with my mail "id:871uv2unfd.fsf@gmail.com" Make these functions accept a pointer to 'notmuch_message_t' as argument and return notmuch_status_t which may be used to check for any error condition. restore: Modify for the new notmuch_database_find_message() new: Modify for the new notmuch_database_find_message_by_filename()
* lib: destroy message object after message removalAli Polatel2011-10-04
| | | | | notmuch_database_remove_message() must call notmuch_message_destroy() once it is done handling message removal.
* lib: bump library minor version because of new symbols.David Bremner2011-09-24
| | | | | This bump is because of the new symbols introduced by the atomicity patches.
* lib: Improve notmuch_database_{add,remove}_message documentation.Austin Clements2011-09-24
| | | | | | | | State up front that these functions may add a filename to an existing message or remove only a filename (and not the message), respectively. Previously, this key information was buried in return value documentation or in "notes", which made it seem secondary to these functions' semantics.
* lib: Wrap notmuch_database_add_message in an atomic section.Austin Clements2011-09-24
| | | | | | | | Adding a message may involve changes to multiple database documents, and thus needs to be done in a transaction. This makes add_message (and, I think, the whole library) atomicity-safe: library callers only needs to use atomic sections if they needs atomicity across multiple library calls.
* lib: Add an API to find a message by filename.Austin Clements2011-09-24
| | | | | | | | | notmuch_database_find_message_by_filename is mostly stolen from notmuch_database_remove_message, so this patch also vastly simplfies the latter using the former. This API is also useful in its own right and will be used in a later patch for eager maildir flag synchronization.
* lib: Remove message document directly after removing the last file name.Austin Clements2011-09-23
| | | | | | | | | | | | Previously, notmuch_database_remove_message would remove the message file name, sync the change to the message document, re-find the message document, and then delete it if there were no more file names. An interruption after sync'ing would result in a file-name-less, permanently un-removable zombie message that would produce errors and odd results in searches. We could wrap this in an atomic section, but it's much simpler to eliminate the round-about approach and just delete the message document instead of sync'ing it if we removed the last filename.
* lib: Indicate if there are more filenames after removal.Austin Clements2011-09-23
| | | | | | Make _notmuch_message_remove_filename return NOTMUCH_STATUS_DUPLICATE_MESSAGE_ID if the message has more filenames and fix callers to handle this.
* lib: Add support for nested atomic sections.Austin Clements2011-09-23
| | | | | | | notmuch_database_t now keeps a nesting count and we only start a transaction or commit for the outermost atomic section. Introduces a new error, NOTMUCH_STATUS_UNBALANCED_ATOMIC.
* lib: Add notmuch_database_{begin,end}_atomic.Austin Clements2011-09-23
| | | | | | These operations translate into non-flushed Xapian transactions, allowing arbitrary groups of database operations to be performed atomically.
* lib: Add missing status check in _notmuch_message_remove_filename.Austin Clements2011-09-12
| | | | | | Previously, this function would synchronize the folder list even if removing the file name failed. Now it returns immediately if removing the file name fails.
* lib/gen-version-script.h: add getline and getdelim to notmuch.sym if neededDavid Bremner2011-09-05
| | | | | | | | If the configure script detects missing getline and/or getdelim symbols, then notmuch will use it's own versions. This patch, based on id:"87k49v12i5.fsf@pc44es141.cs.uni-magdeburg.de" by Matthias Guedemann, adds the symbols to notmuch.sym as well so they are properly exported from the library.
* lib/gen-version-script.sh: replace --defined argument to nm with awkDavid Bremner2011-09-05
| | | | | | | | | | OpenBSD nm apparently doesn't support --defined. The awk condition is based on the assumption that all defined symbols have some hex number in the first column. Thanks to Matthias Guedemann reporting the problem, and an earlier version of this patch.
* re-enable notmuch.sym generation using POSIX sedDavid Bremner2011-08-21
| | | | | | | | | Unfortunately Robin Green's patch 52e4dedf9aa was lost when I created gen-version-script.sh. This merges his changes manually into that script. It turns out tabs seem not needed in version script files, so I simplified a bit and removed the printf. Thanks to Alexander Botero-Lowry for help and testing.
