ISSUE: 5747
|
|
TITLE: Trace duplicates asci_char(13) in its output (Windows only)
|
|
DESCRIPTION:
|
|
We launch trace and create connect to DB with statement line 'select ... from rdb$database'.
|
|
Trace log should contain several lines related to connection, transaction and statement.
|
|
ON WINDOWS these lines should be separated by *pair* of characters: CR + NL.
|
|
Count of these chars should be equal.
|
|
We then open trace log as binary file and read all its content into dict of Counter type,
|
|
thus we can get number of occurences for each character, including CR and NL.
|
|
Finally, we compare number of occurences of CR and NL. Difference has to be no more than 1.
