Whenever transfer.Account() is called, a new goroutine acc.averageLoop()
is started. This goroutine exits only when the channel acc.exit is closed.
acc.exit is closed when acc.Done() is called, which happens during tr.Done().
However, if tr.Reset is called during a copy low level retry, it replaces
the tr.acc, without calling acc.Done(), which results in the goroutine
mentioned above never exiting.
This commit calls acc.Done() during a tr.Reset()
This is possible now that we no longer support go1.12 and brings
rclone into line with standard practices in the Go world.
This also removes errors.New and errors.Errorf from lib/errors and
prefers the stdlib errors package over lib/errors.
Before this fix, on Windows, the --bwlimit would max out at 2.5Gbps
even when set to 10 Gbps.
This turned out to be because of the maximum token bucket size.
This fix scales up the token bucket size linearly above a bwlimit of
2Gbps.
Fixes#5507
Includes adding support for additional size input suffix Mi and MiB, treated equivalent to M.
Extends binary suffix output with letter i, e.g. Ki and Mi.
Centralizes creation of bit/byte unit strings.
This patch adds the missing stats to the output of core/stats
- totalChecks
- totalTransfers
- totalBytes
- eta
This now includes enough information to rebuild the normal stats
output from rclone including percentage completions and ETAs.
Fixes#5116
Before this change the core bandwidth limit was limited to upload or
download value if the other value was off.
This fix only applies a core bandwidth limit when both values are set.
This change decreases the edge limiter burst size which dramatically
increases the smoothness of the bandwidth limiting.
The core bandwidth limiter remains with a large burst so it isn't
affected by double rate limiting on the edge limiters.

This change uses the bwlimit code to apply limits to the receive and
transmit data functions in the HTTP Transport.
This means that all HTTP transactions will have limiting applied -
this includes listings for example.
For HTTP based transorts this makes the limiting in Accounting
redundant and possibly counter productive
This is done by making fs.Config private and attaching it to the
context instead.
The Config should be obtained with fs.GetConfig and fs.AddConfig
should be used to get a new mutable config that can be changed.
Adds a flag, --progress-terminal-title, that when used with --progress,
will print the string `ETA: %s` to the terminal title.
This also adds WriteTerminalTitle to lib/terminal
Before this change we sorted transfers in the stats list solely on
time started. However if --check-first was in use then lots of
transfers could be started in the same millisecond. Because Windows
time resolution is only 1mS this caused the entries to sort equal and
bounce around in the list.
This change fixes the sort so that if the time is equal it uses the
name which should stabilize the order.
Fixes#4599
Before this change the code which summed up the existing transfers
over all the stats groups forgot to add the old transfer time and old
transfers in.
This meant that the speed and elapsedTime got increasingly inaccurate
over time due to the transfers being culled from the list but their
time not being accounted for.
This change adds the old transfers into the sum which fixes the
problem.
This was only a problem over the rc.
Fixes#4569
Before ths fix --cutoff-mode soft and cautious would emit a Fatal
error which stopped the sync immediately.
This fix introduces a new error which is checked in the sync error
processing which stops the sync gracefully.
Fixes#4576
The deadlock was caused in transfermap.go by calling mu.RLock() in one
function then calling it again in a sub function. Normally this is
fine, however this leaves a window where mu.Lock() can be called. When
mu.Lock() is called it doesn't allow the second mu.RLock() and
deadlocks.
Thead 1 Thread 2
String():mu.RLock()
del():mu.Lock()
sortedSlice():mu.RLock() - DEADLOCK
Lesson learnt: don't try using locks recursively ever!
This patch fixes the problem by removing the second mu.RLock(). This
was done by factoring the code that was calling it into the
transfermap.go file so all the locking can be seen at once which was
ultimately the cause of the problem - the code which used the locks
was too far away from the rest of the code using the lock.
This problem was introduced in:
bfa5715017 fs/accounting: sort transfers by start time
Which hasn't been released in a stable version yet
This is preparation for getting the Accounting to check the context,
buf first we need to get it in place. Since this is one of those
changes that makes lots of noise, this is in a seperate commit.
