I'm using pdf because I can comment and bookmark it to facilitate my
reading process. I'm open to any other options. But it seems that
there is no way to comment on chm (Let me know if I'm wrong). Then
probably the solution is to convert html into pdf.

Well...I tried BRB a long time ago.  The lack of a SQL interface was a
show-stopper for me.  Perhaps this will result in a better product.
And that can't be all bad! :-)

Big North American companies like Oracle don't do /anything/ without lawyers.  
It can't be helped in a country like the USA.  Not all lawyers are evil: almost

Not quite the case.  The test suite includes large amounts of code to induce
various faults, track memory, reset various things back to pre-initialized
values etc.  This requires recompiling the SQLite library to get those
various hooks and tweaks.

[sqlite] understanding the logic of licensing various parts of the sqlite family

[P Kishor]

I am simply curious, and want to expand my knowledge of this --

1. sqlite3 code is in public domain.
2. sqlite mark is trademarked.
3. sqlite3 encryption extension is licensed and for a fee, and comes
with a contract to not distribute it further.
4. sqlite code tests are available as long as they are in the
non-amalgamated source tree.
5. other "more complete" code tests are proprietary and closed source.


I am curious about the reason for #5 being the way it is. Simply
curious, not judgmental.

Fwiw, I never 'make test' sqlite... I just download and install it.
Same with the version that comes with DBD::SQLite other than any tests
that the Perl installation might do.

Re: [sqlite] Why is there no test suite for ''make check' ?

[Darren Duncan]

Replying to an earlier post, I remember "make test" working for SQLite when I 
tried it in the past.  I'm actually used to running that, this practice 
ingrained as standard behaviour with Perl and Perl modules, and I usually 
expect 
any other projects to have a "make test" too.  Besides Perl, I know that Git, 
Python, PHP, and SQLite, "make test" works for.

Why is that?  I would have thought that with respect to users of SQLite the 
amalgamation is drop-in-substitutable for the separate files, with the test 
suite mainly testing the collection as a whole.  The test suite being AFAIK 
essentially an application that links against the already-compiled SQLite, at 
which point differences may have gone away.  What subtleties does the test 
suite 
depend on that the same one doesn't work for both versions.

Create the database without indices.  Note the size.  Then add the indices.
 It will be the case that almost all new data is part of the indices.

Read about the file format and pick how to corrupt an index.  Putting
several zero bytes at the beginning of some pages should go a long way.

If SQLite crashes in any way other than reporting an error, then firstly
congratulations on finding a bug, and secondly save the database for DRH and
team to have a look.

Not really the case.  The software that provides documentation in PDF has
usually done so because the help is authored in Latex or a very similar
format.  The GNU standard for documentation (info) was Latex compatible
which is why you'll find most GNU tools do have PDF documentation.

For Python, documentation is authored using Sphinx (and was historically
something similar to Latex).  Sphinx has a way of generating Latex output
which can then be processed into PDF although it is enough of a pain that
most Sphinx projects do not both with PDF.

The documentation for SQLite is not authored in a Latex compatible format
and so isn't trivial to turn into PDF.  You are of course welcome to provide
a tool that does the conversion.

Instead it targets HTML output like pretty much everyone else out there.
You are going to have to get used to this new reality.  If you like PDF
because it gives you a single self contained file that is searchable and
usable offline then I suggest looking into the CHM format.

Note you can download the HTML docs for local offline access.  You can
create a CHM file by creating a small project file and compiling it.  There
is a CHM compiler for Windows, and you can also do so under Linux (google
HHW4Wine).

If you want the PDF for printing then that is a really bad idea as the
documentation is not authored or intended for dead tree - eg it doesn't have
physical pages, and isn't intended to be read with a beginning, middle and
end.  In HTML format it works with any screen size, big or small.  Use your
HTML viewer tools to print it as you see fit.

Is there a a good reason for that? To say I'm building from the right source 
code, but then to not have the test packages seems a bit odd. One might 
reasonably expect some way to test the software no matter what source code one 
uses.

But by implication of what you said earlier, I should be building from the 
amalgamation source code.

I'm not looking for 100% branch coverage. I would like something that I can use 
to be reasonably confident the code is working correctly.

I see.  You are building from the amalgamation.  And you should be too.  But
you are right - we do not ship test suites with the amalgamation.  To use
the free test suite for SQLite, you have to build from canonical source
code.  We have a separate test harness for the amalgamation (the one that
provides 100% branch test coverage) but that one is not free, I'm afraid.

There is only one directory - there is no 'src' directory at all. If you look 
at 
the path what I posted below, you do see 'src' but that is part of the 
directory 
structure in Sage. In other words


~/parallel/sage-4.4.4/spkg/standard/sqlite-3.6.22/src

IS the top level directory in sqlite. (That's assuming some idiot has not 
screwed something up in Sage). I guess I'll need to double check this, but it 
seems unlikely. The 'configure' script creates a Makefile, but that Makefile 
has 
no test/check/fulltest targets.

  This works, but you must give the database file on the command line
  (or use an anonymous database).  You might also want to add -batch.

  As best I can figure, the style the OP asked about (where the
  database file is part of the script) can't be done without a
  wrapper.

  This is still pretty useful, however.

  I wonder if it would be worth creating a -initcli or something that
  simply ignored the first line of input.  It could also imply -batch.

This is how to send a single command to sqlite3:

$ sqlite3 mydatabase.db 'CREATE TABLE myTable (name TEXT, value INTEGER);'

Put as many commands as you like in the quotes:

$ sqlite3 mydatabase.db "CREATE TABLE myTable (name TEXT, value INTEGER);INSERT 
INTO myTable VALUES ('fred', 3);SELECT * FROM myTable"
fred|3

and put as many commands like that as you like in your shell script.

But it's not a neat way of scripting the command-line tool because it requires 
you to create a shellscript with SQL commands in: two languages in the same 
file.  It's neater to make up a proper .sql file with just the SQL commands in, 
then tell the command-line tool to execute the commands from the file.  Here is 
one way to send multiple commands to sqlite3:

$ cat makemydb.sql
CREATE TABLE myTable (name TEXT, value INTEGER);
INSERT INTO myTable VALUES ('fred', 3);
SELECT * FROM myTable;

$ sqlite3 mydatabase.db '.read makemydb.sql'

Here's how you would do it if you didn't know about the '.read' command:

$ cat makemydb.sql | sqlite3 mydatabase.db

Save the output in an output file:

$ cat makemydb.sql | sqlite3 mydatabase.db > saved.txt

If you don't mind one error message then you can do it like this:

#!/usr/bin/sqlite3 -init
;
create table tbl1(one varchar(10), two smallint);
.h on
pragma table_info('tbl1');

Otherwise it's impossible to it because '#' is not a comment-starting

  Not possible.  Shebang assumes the input file can be given as the
  last argument.  sqlite3's options structure is not setup that way.
  Even if it was, shebang generally only works on systems that
  understand "#" as a comment.

  You can get around the first issue with a small wrapper shell
  script, but I don't think you can fix the second problem without
  modifications to sqlite3.

You want to pretend a .sql file is an executable and send commands to
sqlite3?  Try something like this:

[hudson:~] $ cat foo.sql
#!/bin/sh

sqlite3 main.db

I was asking whether it is possible to use Shebang with sqlite script.
If it is possible, would you please show me how to modify the
following script to do so?

$ ./main.sql
Error: unknown command or invalid arguments:  "/main.sql". Enter
".help" for help
$ cat main.sql
#!/usr/bin/sqlite3 main.db

create table tbl1(one varchar(10), two smallint);

[sqlite] Why is there no test suite for ''make check' ?

[Dr. David Kirkby]

I know the SQlite developers take testing quite seriously

http://www.sqlite.org/testing.html

with 679 times as much test code as actual code in the database.

In fact, I've often pointed to the above page when trying to get the developers 
of the Sage maths software to pay a bit more attention to testing.

http://groups.google.co.uk/group/sage-devel/browse_thread/thread/eba06b53be7cd176/e938667e199bfce4?lnk=gst=sqlite#e938667e199bfce4

However, I was somewhat surprised when I run 'make check' to see there is no 
test suite shipped as part of sqlite. Whilst I realise you do  a lot of testing 
and it's impractical for an end user to do all this, I would have thought a 
minimal test suite that tests 100 or so things would be useful. Often bugs in 
compilers or operating systems display bugs that are not seen by the 
developers. 
That would be especially useful if someone is using a rarer platform like AIX, 
HP-UX, or building in a less common way (like forcing 64-bit builds on Solaris, 
as someone was asking about).

Re: [sqlite] sqlite documents in pdf format

[Peng Yu]

Hi Artur,

I could use acrobat to convert the whole website to pdf. Do you know
if there is any particular advantage to use PDF Creator, besides the
latter is free?

Although I could use a software to convert html to pdf, I'd prefer to
have a document in pdf directly. As the pdf file converted from html
has a lot of shortcomings. It is very common that software provide
document in many different format. For example, python, GNU make.

If it is possible, I think that it is making sense to generate pdf
version document as well.

I did send a reply to this a few hours ago, but I see it has not appeared. 
Perhaps it got lost in the ether. Here it is again. I've copied it to you 
personally now, in case for some reason I'm banned from posting to the list, 
but 
I suggest you put any replies on the list.

I can't speak for AIX, but building sqlite 64-bit on OpenSolairs on x64 or 
Solaris 10 on SPARC is quite easy. Just add -m64 to the compiler options 
(CFLAGS).

I know 'sqlite' is used in the Sage maths project, and that is how it is build 
there.

This is a Sun Ultra 27 (quad core Xeon) running OpenSolaris 06/2009

dynamically linked, not stripped


This is a Sun Blade 2000 SPARC running Solaris 10 update 8

local/bin/sqlite3:  ELF 64-bit MSB executable SPARCV9 Version 1, 
dynamically 
linked, not stripped

IMPORTANT

'sqlite' does not appear to have any test suite shipped with it (surprisingly, 
as I know the developers take testing very seriously). I've not actually used 
sqlite, so I don't know if it works when built like this.

64-bit SQLite can cache more than 4Gb of your db.

Re: [sqlite] sqlite documents in pdf format

[Artur Reilin]

HI Peng,

you could install PDFCreator (http://en.pdfforge.org/pdfcreator) then open
the site and print it with PDFCreator. Then you have a pdf-file.

with best wishes

[sqlite] Development snapshots for SQLite 3.7.0 available

[D. Richard Hipp]

On the download page of the draft website:

 http://www.sqlite.org/draft/download.html

you can now find amalgamations (the sqlite3.c source file) for  
development snapshots.  These snapshots are intended for beta-testing  
only.  Interfaces and file formats in these snapshots are subject to  
change.  Nevertheless, these snapshots should be reasonably stable in  
the sense that they pass our internal tests.

It will be a great help to our testing efforts if you will give one of  
these amalgamations a try in your software and report any problems you  
encounter to this mailing list.  Thanks.

Re: [sqlite] 64 bit libsqlite for AIX and Solaris

[Igor Sereda]

What compiler are you using? With GCC, you can use -m64 option. There must be
a similar option in other compilers.

You get the default for whatever platform you're compiling on.
 
Though I'm not sure if there's any advantage/disadvantage to 64-bit binaries 
for sqlite3, is there?

Hi,

I am looking for 64 bit libsqlite for AIX and Solaris. Is there a place from
where I can
get them pre-built ?

I have downloaded sqlite-amalgamation-3.6.23.1.tar and building it. But I
don't see any
option in configure to build it for 64 bits. Will the default library built
be 64 bits. ?
If not, then how to build them ?


Thanks,
Sushil.

Do you have an actual test cases where pOut is uninitialized?  Or are you

[sqlite] Fwd: CRITICAL bug in sqlite3VdbeExec() code

Dear friends,

This is my bug report.

sqlite version: 3.6.23.1, Check-in [2e6a462ceb]
file: vdbe.c
line: 971
function: sqlite3VdbeExec()

description:

Local variable "pOut is not properly initialized in some cases.
For example:


...
/* Opcode: Variable P1 P2 * P4 *
**
** Transfer the values of bound parameter P1 into register P2
**
** If the parameter is named, then its name appears in P4 and P3==1.
** The P4 value is used by sqlite3_bind_parameter_name().
*/
case OP_Variable: {/* out2-prerelease */
  Mem *pVar;   /* Value being transferred */

  assert( pOp->p1>0 && pOp->p1<=p->nVar );
  pVar = >aVar[pOp->p1 - 1];
  if( sqlite3VdbeMemTooBig(pVar) ){

  }
  sqlite3VdbeMemShallowCopy(pOut, pVar, MEM_Static); <<<--- ***  
HERE***
  UPDATE_MAX_BLOBSIZE(pOut);
  break;
}
...

Function sqlite3VdbeMemShallowCopy() is called with pOut == NULL, of  
course with access violation (in Windows version).
"case OP_Variable" I have checked under M$ debugger (not coverable  
errors in my PHP/PDO-Sqlite script with parameters binding), but  
possible other cases in massive switch statement, I think ...

[sqlite] 64 bit libsqlite for AIX and Solaris

[Sushil]

Hi,

I am looking for 64 bit libsqlite for AIX and Solaris. Is there a place from
where I can
get them pre-built ?

I have downloaded sqlite-amalgamation-3.6.23.1.tar and building it. But I
don't see any
option in configure to build it for 64 bits. Will the default library built
be 64 bits. ?
If not, then how to build them ?


Thanks,
Sushil.

Re: [sqlite] Issue with locked journal file

[Filip Navara]

Ok, I'll expand on that suggestion, try PRAGMA journal_mode=truncate;

If you are using TortoiseSVN on the machine than the most likely cause
is the TSVNCache process. We had countless issues with it.

Best regards,
F.N.

SQLite comes with a command-line tool.  You can feed it with individual 
commands on a Unix command-line or tell it to read commands from a file.
