Re: [Firebird-devel] Nightmare debugging FB3

Unlike Ann, I'm not a debugging wizard, but because I couldn't make sense of it by reading the sources, I had to call VS and found that an ACL is corrupt when walk_acl() thinks so and in turn this happens because that function walks uninitialized memory beyond the end of the ACL. The code used in INI_format() needs a second ACL_end and if you debug walk_acl() you will see it reading trash and marking the ACL as corrupt. I'm going to put that extra terminator. Hmmm, this looks like my fault, although I seem to remember that it used to work. Nevermind, both buffers really miss the final ACL_end. Before fixing that error, apparently there was a memory corruption in the engine, because if I tried SHOW TABLE RDB$DATABASE; just after getting (ACL unrecognized), isql crashed. I suspect this is a local ISQL crash, not the engine one. I've been striked by this crash yesterday too, request-startAndSend() fails with SEGV but all pointers were non-NULL.

I would prefer to change the result to plain int, but it may not be possible (I would have to check all places affected). The problem here may be theoretical rather than practical, but it does exist.

Re: [Firebird-devel] Update ICU in Windows
Adriano, With older ICU, you probably used Visual Studio to upgrade older format to newer one. Now, the inverse will be necessary. AFAIK, Nickolay used something for this, but I don't know if it was fully functional or needed manual edits. But note, ICU has not only vcxproj files. It has also mak files and used nmake. Someone may waste a lot of time doing this, and I do not guarantee it will work. So, this is just about technical complexity of the work. Fine with me. Perhaps this issue should be simply re-raised as does anyone here still don't use MSVC10 for v3?

It will spawn firebird.exe per every user connection. firebird.exe will detect this situation and explicitly pass SharedCache = false and SharedDatabase = true via API into all connect calls, thus overriding any underlying config settings. firebird.exe alone will be always working in the multi-threaded mode (thus not requiring the -m switch) supporting either SC or SS, depending on the config settings. So, for CS one will need to install/run fblistener.exe and don't care about anything else. For SS/SC one will need to install/run firebird.exe and setup the config properly (SS by default). The installer will just ask about SharedDatabase/SharedCache (or about CS/SC/SS - although these terms become outdated with v3) and figure out what binary should be installed and whether it's needed to change the config. No eight possible options anymore. Not much harder to understand than for v2.5. Almost same for POSIX and Windows. If SC is going to be deprecated (at least at the installer level), then setup becomes even easier.

Re: [Firebird-devel] Some aspects of the optimizer hints
Ann, The FIRST keyword was added to Firebird's SQL in version 1.0 or 1.1 - in 2000 0r 2001, but the use of FIRST in InterBase goes back much further. It was part of GDML - and it's purpose was to signal that the query should be optimized to walk the index (navigate, in the internals) rather than create a bitmap and access records in storage order. There's no reason to limit the number of record a query returns - when you've seen enough, just close it. The semantic significance of FIRST and its relatives is I want the first records quickly. Quite interesting, thanks. This is really close to what I'm trying to discuss. Although this seems to be lost with time, as InterBase 6.0 had FIRST N clause in GDML acting as a row limit and Firebird's FIRST N clause just reused the same BLR implementation. And the optimizer didn't have any indications to treat blr_first as a hint that time. So, historically, no, it's neither a workaround nor a hack. Here I may agree (knowing the history). Parsing SQL comments ... that sounds like a hack to me. And here I agree as well. Although we've already seen other opinions. Adding yet another non-standard keyword when one already exists and does what you want doesn't appeal all that much either. But the FIRST clause in both SQL and GDML does not act as a hint for the past 15 years (at least). It can surely be considered by the optimizer (and this is already committed to v3.0), but its documented semantics is quite different. So would you consider a connection option? A transaction option? As stated in my initial message, I'm open for opinions in this regard. It could be specified per database, or per connection, or maybe even per transaction (although I doubt it's really needed). But regardless the global level FIRST ROWS is specified as the default behavior, users must be able to alter it to ALL ROWS at the statement level, if required. And it's impossible using the existing syntax. Dmitry -- Rapidly troubleshoot problems before they affect your business.

Re: [Firebird-devel] Some aspects of the optimizer hints
Kjell,
This makes sense, but I also think what Jim Starkey said makes sense,
i.e. that introducing optimizer hints in essence means you've given up
on creating a good automatic optimizer.
Jim is not alone in thinking this way. This is why I explicitly
mentioned that I don't want to discuss either necessity or
implementation of full featured hints in this discussion.
So, when would you need one or the other? As far as I can see, 2) would
be the normal case, and 1) would be used only in the the following two
cases:
1a) You only want the forst N records, possibly not being able to
determine N beforehand. You would normally use FIRST N or ROWS N
(preferred nowadays, isn't it?), but if N isn't known beforehand, this
is not possible.
1b) You want to display/start using something as quickly as possible
and then keep fetching more records (possibly the entires result set) in
the background.
A more common approach might be to fetch the remaining rows by user's
demand. For example, many Delphi applications using DBGrid and its
friends initially fetch only rows fitting just a couple of screens and
continue fetching once user scrolls the grid down.
Would it be possible to allow specification of only the part of the plan
that you want to modify and leave the rest default?
I'd suggest to let the legacy PLAN resting in piece. It's already misses
many optimizer features and will outdate more and more with years.
Would this be possible:
plan hint Movies order IX_MovieName
plan hint Movies natural
plan hint Movies index SomeBetterIndex
This could be suitable for generic hints, but not for the FIRST ROWS vs
ALL ROWS choice, as it affects many optimizer decisions at once.
Something like PLAN FOR {ALL | FIRST} ROWS might be a yet another
syntactical option here, although personally I'd prefer to separate
planning from hinting at the syntax level. So far it was expected
that input (explicitly specified in syntax) and output (reported by the
engine) plans mean the same, but it won't be the case anymore with the
aforementioned approach.

Re: [Firebird-devel] Some aspects of the optimizer hints
Ann, Right. And if you want to give the optimizer a hint that it should choose the second plan, change the query like this: select first 100 * from MOVIES where COMMENTS like '%yacht% order by NAME; If you think your client may want more than a million rows, increase that number. I mentioned this approach in my initial message and it does not look good to me. I treat it as a workaround / hack, not a solution. Of course, we could improve it via some syntax sugar e.g. select first * (without row counter) or select first unlimited *, but it still doesn't look really elegant. Also, there may be (in fact, there are) customers who need the FIRST ROWS strategy being the default one. And rewriting a majority of their queries to include the dummy FIRST clause is not something they can consider seriously. Dmitry -- Rapidly troubleshoot problems before they affect your business.

[Firebird-devel] Some aspects of the optimizer hints
All,
We had this topic raising from time to time, resulted in CORE-1488. So
far there was no appropriate discussion and hence no decision made,
although one might argue that the optimizer should be clever enough to
make hints unnecessary. The PGSQL guys share the same opinion, BTW ;-)
As for me, the ideal optimizer is a purely theoretical thing that can
never exist in the real world, but I'm *not* going to discuss this in
depth now, neither I have time for a full featured implementation of
hints, whatever it would be. However, I'd like to raise one point that's
not generally related to the optimizer quality.
There's a retrieval rule that can be hardly guessed by the optimizer and
that can be specified by the user only. I mean whether the optimization
strategy is targeted at retrieving the whole dataset ASAP or at
retrieving some first part of rows ASAP, at the cost of slower retrieval
of the whole dataset. In the database world, this is commonly known as
ALL ROWS vs FIRST ROWS retrieval strategies.
There's an obvious easy case -- FIRST / ROWS clause -- that clearly
defines user intentions and that can be used by the optimizer to adjust
the retrieval strategy. However, users may want the FIRST ROWS strategy
even in generic queries without using the explicit rows limit. For
example, it's often important to fetch the first screen of the grid and
show those rows to the user immediately while fetching the subsequent
(invisible) rows in the background, thus reducing application response
times. A workaround with something like SELECT FIRST 10 is
possible, but it looks crappy.
In Firebird, the ALL ROWS vs FIRST ROWS choice is mostly about SORT vs
ORDER plans used for sorting/grouping. See CORE-1482 for example. But
there may be other differences in plans, also targeted at different
retrieval strategies (e.g. a hash join is slower in returning the first
rows than a nested loop join).
The good question is how Firebird behaves now from this point of view.
Mostly it uses the ALL ROWS approach, and the underlying cost based
optimization algorithms also deal with complete stream cardinalities.
There are some heuristics based deviations like using the ORDER plan
even when SORT would be faster, and originally I was thinking that we
have some intermediate mode (DEFAULT / UNKNOWN ROWS), but later I came
to conclusion that usage of more advanced statistics (e.g. index
clustering factor that's already available in GSTAT output in v3) will
change the behaviour in the right direction. So we may treat Firebird
basically preferring the ALL ROWS mode now and becoming even stricter in
this regard in the future.
This makes it necessary to allow the FIRST ROWS mode when it's needed.
I'm proposing the following:
1) FIRST ROWS mode is implicitly used when the FIRST / ROWS clause is in
game. Also, FIRST ROWS mode is implicitly used for EXISTS / ANY subqueries.
2) An explicit clause is introduced to force the non-default mode (ALL
ROWS for FIRST-claused queries and FIRST ROWS for other queries). Hating
Oracle-like pseudo-comments with embedded hints and preferring explicit
syntax, I suggest (inspired by DB2):
SELECT ...
[OPTIMIZE FOR {FIRST | ALL} ROWS]
3) Either PLAN or OPTIMIZE clause can be used, syntax error is thrown if
both are specified.
4) Explicitly specified mode takes precedence over implicitly deducted one.
5) ALL ROWS mode is the default one for queries without FIRST / ROWS
clause. Whether the default mode can be altered per database (via
configuration file) or per session is discussable.
6) OPTIMIZE FOR FIRST number ROWS can be added later to better assist
the optimizer in specific cases.
7) OPTIMIZE clause can be later extended for full featured hints if/when
they will be agreed on. Possible extentions (off the top of my head):
OPTIMIZE [NOT] USING INDEX index
or
OPTIMIZE USING HASH JOIN FOR (table1, table2)
or
OPTIMIZE ENFORCE JOIN ORDER
etc
As so far we speak about optimization of the final (user retrievable)
datasets, it makes sense to use the OPTIMIZE clause at the top level
only, i.e. for select statements but not for select expressions. This is
similar to how WITH LOCK and FOR UPDATE clauses are used. However, full
featured hints should be available to select expressions as well. I'm
not sure whether we should choose a protecting syntax now and extend
it (compatibly!) later, or allow FIRST / ALL ROWS rules for subqueries
since the beginning, or parse the hints and throw context based errors
if necessary.
Your opinions are appreciated.

I'd actually prefer comments like Oracle does. I think it is better for portability. Given e.g. FIRST vs TOP vs ROW_NUMBER mess developed by different vendors, I wouldn't care much about cross-database portability. Hints are outside the SQL standard, but many other features are not there either. I hope you don't suggest to implement everything non-standard in the comments, do you? SQL is a declarative language, so let's allow users to declare what they need using the language itself. If we go with comments, I'd suggest that throwing exceptions for hints should be optional (for portability), maybe using a dpb item to turn it off (default on), or a server- or database specific config option.

That's not dangerous at alpha stage, but may be I've missed something? Were you going to make missing fields in system tables have NULL value? That does not work. AFAIK, FB3 describes system tables based on their static definitions (INI), not on their real format on disk. So it expects the bigger record length and bugchecks while decompressing the record. The trick with non-existing fields work only after the record is decoded into a known format, thus it doesn't work. On a positive side, the current behavior allows to query changed MON$-tables immediately with the new engine and old database, without backup/restore. On a negative side, changes in persistent system tables make the existing database unusable, thus requiring backup/restore. Dunno what is more important.

[Firebird-devel] Explained plan output: feedback wanted
All, There are some kinds of queries that have data access methods linked to each other. Windowed functions are the obvious example, but it happens even for regular aggregate functions. For example, COUNT(DISTINCT) needs not only read the underlying stream but also sort it in order to eliminate duplicates. So we have both retrieval and sorting inside the aggregation node and sorting is based on the retrieval: select count(distinct rdb$relation_id) from rdb$relations group by rdb$relation_name Select Expression - Aggregate - Table RDB$RELATIONS Access By ID - Index RDB$INDEX_0 Scan /* - Sort (unique) - Table RDB$RELATIONS Access By ID - Index RDB$INDEX_0 Scan */ However, I'd like to skip the repeating part and replace it with a reference to the earier introduced part, because technically there's only one retrieval, not two. The possible options are: (A) Select Expression - Aggregate - Table RDB$RELATIONS Access By ID - Index RDB$INDEX_0 Scan - Sort (unique) where no input for sorting means the prior stream (B) Select Expression - Aggregate - Table RDB$RELATIONS Access By ID - Index RDB$INDEX_0 Scan - Sort (unique) - ^^^ which means to look above for the input stream. But the indentation makes it hard to understand what exactly we refer to. And theoretically there maybe references to farther parts of the plan, not only the neighbours. (C) Select Expression - Aggregate - Table RDB$RELATIONS Access By ID - Index RDB$INDEX_0 Scan - Sort (unique) - $base$ some keyword is used to refer to the input stream of the aggregation (D) Select Expression - Aggregate - 1: Table RDB$RELATIONS Access By ID - Index RDB$INDEX_0 Scan - 2: Sort (unique) - $(1) all non-trivial methods have their children enumerated so they can be referenced by numbers. But for complex queries there will be multiple (1)s and (2)s making it harder to match the proper one. (E) Select Expression - 1: Aggregate - 2: Table RDB$RELATIONS Access By ID - 3: Index RDB$INDEX_0 Scan - 4: Sort (unique) - $(2) or Select Expression 1: - Aggregate 2:- Table RDB$RELATIONS Access By ID 3: - Index RDB$INDEX_0 Scan 4:- Sort (unique) 5: - $(2) all methods are globally enumerated. The output is a bit noisy, but personally I favor (E)#2 so far. Comments anyone? Other suggestions? Dmitry -- Get 100% visibility into Java/.NET code with AppDynamics Lite!

This makes the interface hardly usable and plays against the long-term success of the new API. The fact that the old API emulation is stacked on top of the new API (thus possibly requiring a conversion between proper and legacy property values) could be a problem here, but it must be solved. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://tracker.firebirdsql.org/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira -- Get 100% visibility into Java/.NET code with AppDynamics Lite!

Next issues were discovered via FDB test suite. Tested on 64-bit Linux,

Were connections true local (embedded) or via localhost?
1. cursor.rowcount (isc_dsql_sql_info with isc_info_sql_records) returns
1 instead expected 6
cur.execute('select * from project')
self.assertEqual(cur.rowcount,0)
cur.fetchone()
self.assertEqual(cur.rowcount,6) --
Correct for embedded connections (no record prefetch), incorrect for
remote connections (including localhost).
2. MON$ATTACHMENTS. Next columns are NULL: MON$REMOTE_PROTOCOL,
mon$remote_address, mon$remote_pid, mon$remote_process.
MON$REMOTE_PROTOCOL, MON$REMOTE_ADDRESS:
Correct for embedded connections (no network layer involved), incorrect
for remote connections (including localhost).
MON$REMOTE_PID, MON$REMOTE_PROCESS:
Should always be present, unless you had connected via some old
fbclient. To be validated.
3. Unexpected RDB$VALID_BLR = True on stored procedure in database
restored by v3.0
Why is it unexpected?
4. Can't get list of users via services API. Returns:
Unable to perform the requested Service API action:
- SQLCODE: -901
- unrecognized service parameter block
- All services except for getting server log require switches'
-901
335544562
BTW, Flamerobin fails with the same error on attempt to get list of
users from server.
5. Call to isc_service_query with isc_info_svc_running raises error:
Services/isc_service_query:
- SQLCODE: -901
- invalid service handle'
-901
335544559
Service handle is valid. This call fails ONLY before some actions are
requested (via isc_service_start),
for example isc_action_svc_get_ib_log. Once any service is started,
isc_service_query starts to work properly.
Sounds like a bug.

[Firebird-devel] [FB-Tracker] Created: (CORE-4127) Server crashes instead of reporting the error key size exceeds implementation restriction
Server crashes instead of reporting the error key size exceeds implementation
restriction
---
Key: CORE-4127
URL: http://tracker.firebirdsql.org/browse/CORE-4127
Project: Firebird Core
Issue Type: Bug
Components: Engine
Affects Versions: 2.5.2 Update 1, 2.1.5 Update 1, 2.5.2, 2.1.5, 2.0.7,
2.5.1, 2.1.4, 2.5.0, 2.0.6, 3.0 Initial, 2.1.3, 2.1.2, 2.0.5, 2.1.1, 2.1.0
Reporter: Dmitry Yemanov
The local buffer of MAX_KEY (4096) bytes overflows thus corrupting the stack
and causing the engine to crash. Only compound indices are affected.
Test case:
recreate table tab1 (col1 int, col2 char(10));
create index itab1 on tab1 (col1, col2);
select * from tab1 where col1 = 1 and col2 = lpad('a', 5000)
