We use the system commands "git-receive-pack", "git-upload-pack" and
"git-upload-archive". they need to be installed and in your system's
PATH. Since we execute system commands we have no direct control on
file creation/deletion and so quota check is suboptimal: if quota is
enabled, the number of files is checked at the command begin and not
while new files are created.
The allowed size is calculated as the difference between the max quota
and the used one. The command is aborted if it uploads more bytes than
the remaining allowed size calculated at the command start. Quotas are
recalculated at the command end with a full home directory scan, this
could be heavy for big directories.
md5sum, sha1sum are used by rclone.
cd, pwd improve the support for RemoteFiles mobile app.
These commands are all implemented inside SFTPGo so they work even
if the matching system commands are not available, for example on Windows
added matching permissions too and a new setting "setstat_mode".
Setting setstat_mode to 1 you can keep the previous behaviour that
silently ignore setstat requests
we have not known bugs with the previous implementation anyway this one
is cleaner: the underlying network connection is directly related with
SFTP/SCP connections.
This should better protect us against buggy clients and edge cases
we support resume only if the client sets the correct offset while resuming
the upload.
Based on the specs the offset is optional for resume, but all the tested
clients sets a right offset.
If an invalid offset is given we interrupt the transfer with the error
"Invalid write offset ..."
See https://github.com/pkg/sftp/issues/295
This commit add a new upload mode: "atomic with resume support", this acts
as atomic but if there is an upload error the temporary file is renamed
to the requested path and not deleted, this way a client can reconnect
and resume the upload
* created a "Log" function for type "Connection"
* created a "log" function for type "Provider"
* replace logger calls to Log/log where possible
I also renamed PGSSQL to PGSQL, as this seemed to be a typo

SCP is an experimental feature, we have our own SCP implementation
since we can't rely on scp system command to proper handle permissions,
quota and user's home dir restrictions. The SCP protocol is quite simple
but there is no official docs about it, so we need more testing and
feedbacks before enabling it by default.
We may not handle some borderline cases or have sneaky bugs.
This commit contains some breaking changes to the REST API.
SFTPGo API should be stable now and I hope no more breaking changes
before the first stable release.
