disconnect database during the work #7953

System information:

  • Operating system (distribution) and version WINDOWS 10 64bit
  • DBeaver version 6.3.0 EE

Describe the problem you’re observing:

2 database on my server. I am working with database1.
Then i click on database2 on the left objects tree 15 minutes ago, then go to the db scheme, then click on table name tabledb2.

DBeaver show me modal window

Connection with database2 lost
Reason:
the connection has already been closed

with button
RECONNECT OK DESCRIPTION

Nevertheless under this window i can see that DBeaver reconnecting herself and show correct data from this table tabledb2.

I do not need this modal window and
i do not need a RECONNECT button!! This should be done automatically.

This modal window show for me every 2-3 hours

Include any warning/errors/backtraces from the logs

Hello guys, I have a problem when I try to connect to a PostgreSQL database , the connection goes perfect in DbEaver but it’s not for cloudbeaver + tunnel test goes successfully :

PostgreSQL partial function DDL shown #8784

  • Operating system (distribution) and version: Ubuntu 20
  • DBeaver version: 7.0.5
  • Database: PostgreSQL 12

Sometimes (i cant reproduce exactly, but it appears from time to time) when I open function editor — i cant see the beginning of a function e.g. I see:

Refresh of objects in the tree helps.

The text was updated successfully, but these errors were encountered:

Hi @plotn ,
unfortunately, cannot reproduce an issue.
Probably you’ve got «Show header» option disable?

Definetely no, cause refresh of the whole tree helps. And I didnt ever new about this option before.
I cant reproduce it stable too, but it happens (under, probably some specific circumstances).
If I get some glue, I will add more details.

Some add info. When this happens — every function in the database become headless. When I press show/hide header code flickers, but no changes (button becomes pressed and unpressed normally).
Neighbour database shows good code — with headers, with ability to switch them on and off.
Reconnect button helps — after reconnect newly opened windows contains full text of functions.

I suspect that it can be rely on the connection, because I work with remote databases, then close notebook, then open it again. Normally bases reconnect in the background, but there is such situation.

still cannot reproduce it.
@plotn does issue still occur?

It surely have dependency with lost connection — try to play with it (even plug in and out cable physically).
There is more interesting bug — when reconnect, some windows stays «buggy» (with no connection) and «newly created» are normal.

still can’t reproduce it. could you try to write steps to reproduce?

I’ll try. Dont close please.

@plotn any updates?
could you check if the issue is actual for you against the recent version?
thanks in advance

Hi! everything is the same. I cant reproduce, but I can explain.
It is surely appears, when there is something with connection. Fresh case. I have database, connection was lost, then it autoreconnected. I can make «select 1» in SQL window, it is ok.
Then I click on the function in the tree. Text appeared without header (begins with «declare ..»). «Show headers» is on. I thy to switch «show headers», text blinking, but headers is not shown.
Then I press refresh (only this function) in the tree. Dialog «connection was invalidated» appears, function is shown correctly with header.
Maybe you can add some specific logs?

Could it be similar to truth?:

another issue — connection was lost. I perform sql query — it tries to reconnect, and connects succesfully.
but then says: ‘SQL Error [08003]: Соединение уже было закрыто’

Only works in new window with the same connection.

could you try to change Keep-Alive value to different from null and check if issue is still persisting?

there are not any updates for a long time
Issue is closed.

Lost connection inconvience — postgres

Hi! I’m using dbeaver for year or two and some bug constantly remains — if the connection is lost (even if «for now» it was refsreshed and «good») and we have some (many) windows open, the behaviour is as follows:

  1. I try to run script in the old windows;
  2. A number of «reconnecting» windows appears (and reconnect finished happily);
  3. But whe windows says: «connection was closed».

The only thing helps — copy script to clipboard, then instantly open new windows (ctrl+]), then paste and run. It works perfectly.

Matvey16

Please clarify some things so we could look deeper into it.

  1. What Database are you using? Postgres?
  2. What version of DBeaver are you using (You can click Help -> About to look for it)
  3. What is disconnecting from the internet? PC with DBeaver or Database server?
  4. What script are you executing before encountering this problem?

plotn

  1. Postges :) as written in title (version 12, 13)
  2. Always maximally fresh
  3. Database (vpn swithces off, so db become unreachable)
  4. It doesnt matter (select).

Matvey16

Please attach logs that are presented after you encounter this problem.
I tried to reproduce it and while the initial run of the script was not possible after loosing connection. Clicking invalidate/reconnect button fixed it, and I was able to run this script in the same window.

plotn

uslss

there is no update on the issue for a long time. if it is still actual — feel free to reopen it

plotn

@uslss, why did you close the issue? I gave all that you asked from me, problem is still exists, whats wrong?

Matvey16

@plotn Hello, I was reviewing this issue, and the error This connection has been closed can be constantly reproduced, but I need to know if you have tried to use Invalidate/reconnect button. Also useful would be to know your connection specifications. Do you use SSH tunnel, proxy, SSL?

plotn

@Matvey16 , got this again. Version: 21.2.2.202110030714
Steps:

  1. Run query in sql editor. Result: SQL Error [08003]: Соединение уже было закрыто
  2. Refresh connection (right click in tree, select «Refresh»
  3. Run query again. Same result.
  4. Open new tab (Ctrl + ]). Run query inside it. All ok.

No tunnels, no ssh, direct connection (via enterprise VPN).

Matvey16

@plotn I see. The refresh button is used to read the metadata of the database if it was changed (for example DDL was executed in SQL editor). The button you are looking for is Invalidate/reconnect or in russian version Проверить соединение. It is used to invalidate reconnection after network changes or session close.

3cywczqyQE

plotn

Ok, I’ll check it. But the situation is still incorrect — the «orphaned» windows tries to reconnect, successfully reconnect, but cannot run query saing «the connection was closed»

plotn

The situation happened.
I press «Invalidate/reconnect» — message appears «Datasource was invalidated»
I go to problem window, run sql. «Datasource was invalidated» blinking 6 times, then «Connection was closed» written.

@plotn, Hi, can you tell me more details about your VPN, does it have firewall or proxy? I tried to reproduce this issue with multiple VPN setups and it worked correctly.

plotn

Hi! Did logs help or not? I use Check Point mobile software

Destrolaric

In logs, there is information that the connection was spoiled. But it’s hard to determine why it couldn’t reconnect.

Destrolaric

@plotn Problem may be related to the proxy. Does your VPN has a proxy server configured?

n5a5

I think this issue is PG-specific and related to its unique connection handling.

n5a5

@plotn Problem may be related to the proxy. Does your VPN has a proxy server configured?

I’ve discussed it privately. They do not use proxy nor PGBouncer.

Приложение A. Коды ошибок PostgreSQL

Всем сообщениям, которые выдаёт сервер PostgreSQL , назначены пятисимвольные коды ошибок, соответствующие кодам «SQLSTATE» , описанным в стандарте SQL. Приложения, которые должны знать, какое условие ошибки имело место, обычно проверяют код ошибки и только потом обращаются к текстовому сообщению об ошибке. Коды ошибок, скорее всего, не изменятся от выпуска к выпуску PostgreSQL , и они не меняются при локализации как сообщения об ошибках. Заметьте, что отдельные, но не все коды ошибок, которые выдаёт PostgreSQL , определены стандартом SQL; некоторые дополнительные коды ошибок для условий, не описанных стандартом, были добавлены независимо или позаимствованы из других баз данных.

Согласно стандарту, первые два символа кода ошибки обозначают класс ошибок, а последние три символа обозначают определённое условие в этом классе. Таким образом, приложение, не знающее значение определённого кода ошибки, всё же может понять, что делать, по классу ошибки.

В Таблице A-1 перечислены все коды ошибок, определённые в PostgreSQL 9.4.1. (Некоторые коды в настоящее время не используются, хотя они определены в стандарте SQL.) Также показаны классы ошибок. Для каждого класса ошибок имеется «стандартный» код ошибки с последними тремя символами 000. Этот код выдаётся только для таких условий ошибок, которые относятся к определённому классу, но не имеют более определённого кода.

Символ, указанный в колонке «Имя условия» , определяет условие в PL/pgSQL . Имена условий могут записываться в верхнем или нижнем регистре. (Заметьте, что PL/pgSQL , в отличие от ошибок, не распознаёт предупреждения; то есть классы 00, 01 и 02.)

Для некоторых типов ошибок сервер сообщает имя объекта базы данных (таблица, колонка таблицы, тип данных или ограничение), связанного с ошибкой; например, имя уникального ограничения, вызвавшего ошибку unique_violation. Такие имена передаются в отдельных полях сообщения об ошибке, чтобы приложениям не пришлось извлекать его из возможно локализованного текста ошибки для человека. На момент выхода PostgreSQL 9.3 полностью охватывались только ошибки класса SQLSTATE 23 (нарушения ограничений целостности), но в будущем должны быть охвачены и другие классы.

Sql error 08003 соединение уже было закрыто postgres

All messages emitted by the PostgreSQL server are assigned five-character error codes that follow the SQL standard’s conventions for “ SQLSTATE ” codes. Applications that need to know which error condition has occurred should usually test the error code, rather than looking at the textual error message. The error codes are less likely to change across PostgreSQL releases, and also are not subject to change due to localization of error messages. Note that some, but not all, of the error codes produced by PostgreSQL are defined by the SQL standard; some additional error codes for conditions not defined by the standard have been invented or borrowed from other databases.

According to the standard, the first two characters of an error code denote a class of errors, while the last three characters indicate a specific condition within that class. Thus, an application that does not recognize the specific error code might still be able to infer what to do from the error class.

Table A.1 lists all the error codes defined in PostgreSQL 15.1. (Some are not actually used at present, but are defined by the SQL standard.) The error classes are also shown. For each error class there is a “ standard ” error code having the last three characters 000 . This code is used only for error conditions that fall within the class but do not have any more-specific code assigned.

The symbol shown in the column “ Condition Name ” is the condition name to use in PL/pgSQL . Condition names can be written in either upper or lower case. (Note that PL/pgSQL does not recognize warning, as opposed to error, condition names; those are classes 00, 01, and 02.)

For some types of errors, the server reports the name of a database object (a table, table column, data type, or constraint) associated with the error; for example, the name of the unique constraint that caused a unique_violation error. Such names are supplied in separate fields of the error report message so that applications need not try to extract them from the possibly-localized human-readable text of the message. As of PostgreSQL 9.3, complete coverage for this feature exists only for errors in SQLSTATE class 23 (integrity constraint violation), but this is likely to be expanded in future.
