Accept a subcommand as an alternative to the --generate option. It
accepts a custom config directory through either the --home or
--config options, using the default location if neither is given.
Add the options --gui-user and --gui-password to "generate", but not
the "serve --generate" option form. If either is given, an existing
config will not abort the command, but rather load, modify and save it
with the new credentials. The password can be read from standard
input by passing only a single dash as argument.
Config modification is skipped if the value matches what's already in
the config.
* cmd/syncthing: Utilize lib/locations package in generate().
Instead of manually joining paths with "magic" file names, get them
from the centralized locations helper lib.
* cmd/syncthing: Simplify logging for --generate option.
Visible change: No more timestamp prefixes.
What hash is used to store the password should ideally be an
implementation detail, so that every user of the GUIConfiguration
object automatically agrees on how to handle it. That is currently
distribututed over the confighandler.go and api_auth.go files, plus
tests.
Add the SetHasedPassword() / CompareHashedPassword() API to keep the
hashing method encapsulated. Add a separate test for it and adjust
other users and tests. Remove all deprecated imports of the bcrypt
package.
LoadOrGenerateCertificate() takes two file path arguments, but then
uses the locations package to determine the actual path. Fix that
with a minimally invasive change, by using the arguments instead.
Factor out GenerateCertificate().
The only caller of this function is cmd/syncthing, which passes the
same values, so this is technically a no-op.
* lib/tlsutil: Make storing generated certificate optional. Avoid
temporary cert and key files in tests, keep cert in memory.
Consistently use double dashes and fix typos -conf, -data-dir and
-verify.
Applies also to tests running the syncthing binary for consistency.
* Fix mismatched option name --conf in cli subcommand.
According to the source code comments, the cli option flags should
mirror those from the serve subcommand where applicable. That one is
actually called --config though.
* cli: Fix help text option placeholders.
The urfave/cli package uses the Value field of StringFlag to provide a
default value, not to name the placeholder. That is instead done with
backticks around some part of the Usage field.
* cli: Add missing --data flag in subcommand help text.
The urfave/cli based option parsing uses a fake flags collection to
generate help texts matching the used global options. But the --data
option was omitted from it, although it is definitely required when
using --config as well. Note that it cannot just be ignored, as some
debug stuff actually uses the DB:
syncthing cli --data=/bar --config=/foo debug index dump
By truncating time.Time to an int64 nanosecond count, we lose the
ability to precisely order timestamps before 1678 or after 2262, but we
gain (linux/amd64, Go 1.17.1):
name old time/op new time/op delta
JobQueuePushPopDone10k-8 2.85ms ± 5% 2.29ms ± 2% -19.80% (p=0.000 n=20+18)
JobQueueBump-8 34.0µs ± 1% 29.8µs ± 1% -12.35% (p=0.000 n=19+19)
name old alloc/op new alloc/op delta
JobQueuePushPopDone10k-8 2.56MB ± 0% 1.76MB ± 0% -31.31% (p=0.000 n=18+13)
name old allocs/op new allocs/op delta
JobQueuePushPopDone10k-8 23.0 ± 0% 23.0 ± 0% ~ (all equal)
Results for BenchmarkJobQueueBump are with the fixed version, which no
longer depends on b.N for the amount of work performed. rand.Rand.Intn
is cheap at ~10ns per iteration.
Like Windows and Mac, Android is also an interactive operating system.
On top of that, it usually runs on much slower hardware than the other
two. Because of that, it makes sense to limit the number of hashes used
by default there too.

Registry.Get used a full sort to get the minimum of a list, and the sort
was broken because util.AddressUnspecifiedLess assumed it could find out
whether an address is IPv4 or IPv6 from its Network method. However,
net.(TCP|UDP)Addr.Network always returns "tcp"/"udp".
The current detection is flawed, because it looks for a few specific
file systems like "msdos" or "fat" to set the mtime window, while in
reality Android seems to report names like "fuseblk", which can stand
for fat, ext4, or even f2fs.
At the moment, we set the mtime window only for a few known names used
for the fat filesystem. With this change, we take a safer approach of
always setting the time window unless we explicitly detect file systems
like ext2/ext3/ex4, which are known not to experience issues with moving
timestamps on Android.
