ISSUE: 6506
|
||||
TITLE: gbak with PIPE to stdout: invalid content if user '-se <host>:service_mgr' command switch
|
||||
DESCRIPTION:
|
||||
NB: bug can be reproduced only if we create batch file and run it from Python using shell invocation,
|
||||
i.e. via subprocess.call(). Python builtin PIPE mechanism does not show any errors.
|
||||
For this reason, we create temp batch scenario, add necessary commands there and run it.
|
||||
Currently this scenario exists only for Windows. It will be implemented for POSIX later.
|
||||
|
||||
Confirmed bug on 3.0.6.33276, 4.0.0.1850.
|
||||
Works fine on 3.0.6.33277, 4.0.0.1854

NOTES:
|
||||
[29.08.2022] pzotov
|
||||
1. Re-checked on 3.0.6.33276, 4.0.0.1850 - problem confirmed.
|
||||
2. Checked on 5.0.0.691, 4.0.1.2692, 3.0.8.33535 - both Windows and Linux.
|
||||
3. In case when '-user ... -pas ...' is missed in p_sender command, error message looks weird
|
||||
(and the same as it was originally detected and shown in this ticket):
|
||||
gbak: ERROR:expected backup description record
|
||||
gbak:Exiting before completion due to errors
