Hi, You can't use isc_info_svc_line for sending backup file to the service. The right token is isc_info_svc_stdin. However, you have to send isc_info_svc_line request along with it to get output from service to detect that restore finished (value zero for reply to isc_info_svc_stdin is just a signal that no stdin input is needed right now).
The reason why isc_info_svc_to_eof doesn't works here is IMHO because this token returns after output buffer is full, not when any further output is available like isc_info_svc_line (because output is always produced in form of lines). Restore via service using stdin is kind of a hack implementation that require client to mix up two parallel "conversations" in single message exchange loop: a) handling service request for stdin input b) service stdout output because it's the only way how client can detect that the restore finished (hence the need for isc_spb_verbose in restore request). Until stdin is fully transmited service may need another chunk, but reply to application is blocked until stdout buffer (eof request) is full, so everything gets stuck (service will not ask for further input because there is not enough output to send the request). isc_info_svc_to_eof *may* work once whole backup stream is sent to the service, so only stdout output is is service's reply (stdin reply is zero), but there is no need to complicate the implementation at client side to handle both output methods. You may take a look at local_restore() implementation in FDB driver v1.8. best regards Pavel Cisar IBPhoenix Dne 3.10.2017 v 16:30 Dimitry Sibiryakov s...@ibphoenix.com [firebird-support] napsal(a): > Hello. > > When I use isc_info_svc_line for sending a piece of backup to server, > everything works > well.
