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
The update is atomic so no transaction is needed.
Addionally a transaction will ask for a new connection to the pool
and this can deadlock if the pool has a max connection limit too low.
Also make configurable the pool size instead of hard code to the cpu number.
Fixes#47
viper will not use env vars if no configuration file is found
https://github.com/spf13/viper/issues/584
As workaround we could manually bind/set a default for each configuration
option using viper.SetDefault("key") and then generate a default config
using viper.Get("key").
This manual solution is error prone and it will become increasingly
difficult to maintain since the configuration options will grow, so
we avoid it for now.
Let's see if viper will solve this issue
Fixes#35
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.
Added a compatibility layer that will convert newline delimited keys to array
when the user is fetched from the database.
This code will be removed in future versions please update your public keys,
you only need to resave the users using the REST API.
