|
| -This directory contains a partial snapshot of the sqlite library from
|
| -http://sqlite.org.
|
| -
|
| -Current version: 3.5.3, released 23-Nov-2007.
|
| -
|
| -(This was built as 3.4.2 [13-Aug-2007] as described below, with the four
|
| -intervening patches 4315, 4427, 4546, and 4556 applied by hand.)
|
| -
|
| -To import a new snapshot of sqlite:
|
| -
|
| -- Visit http://sqlite.org/download.html and download the latest source
|
| - distribution.
|
| -- Unpack the source on a Linux machine.
|
| -- Change to the source directory and run:
|
| - $ ./configure --disable-tcl # build headers
|
| - $ make # build some generated files
|
| -- Copy the generated .c/.h files from the sqlite directory to this directory,
|
| - as well as those in src/ and ext/fts2/. Omit files which have been omitted
|
| - here. Here's an easy way to be sure you get everything:
|
| - $ cp /path/to/source/*.[ch] . # don't forget subdirs, too
|
| - $ gvn status | grep -v ^M # print the names of all new files
|
| - $ mkdir new; mv each new file to new
|
| - Then rebuild, and if any of the files in new/ are needed, move them
|
| - back into this directory, add them to the project, and "gvn add" them.
|
| -- Apply the preload-cache.diff (see below)
|
| -- Update this README to reflect the new version number.
|
| -
|
| -Modifications for this release:
|
| -- I marked all changes I made with "evanm", so you can find them with
|
| - "grep evanm *".
|
| -- Most files include sqlite3ext.h with SQLITE_CORE #defined, but two don't:
|
| - fts2_tokenizer.c and icu.c. Without this #define, the calls in
|
| - fts2_tokenizer.c try to go through some pointer to the sqlite API instead of
|
| - calling the functions directly (to work as a loadable module), but then crash
|
| - (because the other files never initialize that loadable module support). As
|
| - a hack I #defined it in these files, but it'd be nice to figure out what
|
| - really ought to happen here (perhaps this file is new and hasn't been tested
|
| - to verify it works right).
|
| -- shell_icu.c is a Chrome-specific file used to load our ICU data. shell.c
|
| - has been modifed to call into shell_icu.c.
|
| -- fts2_icu.c has a critical bug. U8_NEXT is used over a UTF-16 string. It's replaced
|
| - by U16_NEXT (jungshik)
|
| -
|
| -Patch
|
| ------
|
| -The file preload-cache.diff patch must be applied to add a new function we use
|
| -to prime the database cache. It allows much faster performance by reading the
|
| -file in one contiguous operation rather than bringing it in organically, which
|
| -involves a lot of seeking.
|
| -
|
| -FTS2 modification
|
| ------------------
|
| -In fts2.c, we added an additional check from fts3 to try to catch some
|
| -additional problems. In buildTerms on line 3807, we replaced
|
| - if( iPosition<0 ){
|
| -with:
|
| - if( iPosition<0 || pToken == NULL || nTokenBytes == 0 ){
|
| -It is from this change to sqlite:
