ISSUE: 2897
|
|
TITLE: Success message when connecting to tiny trash database file
|
|
DESCRIPTION:
|
|
We make invalid FDB file by creating binary file and write small string in it (text: 'ŒåŁä').
|
|
Then we try to connect to such "database" using ISQL with passing trivial command
|
|
like 'select current_timestamp' for execution.
|
|
ISQL must raise error and quit (obviously without any result to STDOUT).
|
|
|
|
STDERR differs dependign on OS.
|
|
First line in error message is the same on Windows and Linux: "Statement failed, SQLSTATE = 08001",
|
|
but starting from 2nd line messages differ:
|
|
1) Windows:
|
|
I/O error during "ReadFile" operation for file "..."
|
|
-Error while trying to read from file
|
|
2) Linux:
|
|
I/O error during "read" operation for file "..."
|
|
-File size is less than expected
|
|
|
|
::: NOTE ABOUT WINDOWS :::
|
|
On Windows additional message did appear at last line, and it could be in localized form:
|
|
-Overlapped I/O operation is in progress
|
|
(only FB 4.0.x and 5.0.x were affected; NO such problem with FB 3.x)
|
|
|
|
This has been considered as bug (see letter from Vlad, 16.09.2021 10:16, subject: "What to do with test for CORE-2484"),
|
|
but if we want to check for presence of this message then we have to use codecs.open() invocation with suppressing
|
|
with encoding = 'ascii' and suppressing non-writeable characters by specifying: errors = 'ignore'
|
|
This bug was fixed long after time when this test was implemented:
|
|
1) v4.0-release: fixed 19.09.2021 17:22, commit:
