Nick Craig-Wood	1f9a79ef09	operations: use less memory when doing multithread uploads ... For uploads which are coming from disk or going to disk or going to a backend which doesn't need to seek except for retries this doesn't buffer the input. This dramatically reduces rclone's memory usage. Fixes #7350	2023-11-20 18:07:05 +00:00

Pat Patterson	71f2883562	operations: ensure concurrency is no greater than the number of chunks - fixes #7299	2023-09-13 12:12:27 +01:00
Nick Craig-Wood	2db0e23584	backends: change OpenChunkWriter interface to allow backend concurrency override ... Before this change the concurrency used for an upload was rather inconsistent. - if size below `--backend-upload-cutoff` (default 200M) do single part upload. - if size below `--multi-thread-cutoff` (default 256M) or using streaming uploads (eg `rclone rcat) do multipart upload using `--backend-upload-concurrency` to set the concurrency used by the uploader. - otherwise do multipart upload using `--multi-thread-streams` to set the concurrency. This change makes the default for the concurrency used be the `--backend-upload-concurrency`. If `--multi-thread-streams` is set and larger than the `--backend-upload-concurrency` then that will be used instead. This means that if the user sets `--backend-upload-concurrency` then it will be obeyed for all multipart/multi-thread transfers and the user can override them all with `--multi-thread-streams`.

Nick Craig-Wood	1b5b36523b	operations: fix accounting for multi-thread transfers ... This stops the accounting moving in large chunks and gets it to move as the data is read out of the buffer.	2023-08-24 17:51:36 +01:00
Nick Craig-Wood	2f424ceecf	operations: don't buffer when a backend implements OpenWriterAt ... In this case we don't seek on errors so no need for seeking.	2023-08-24 17:51:36 +01:00
Nick Craig-Wood	d4cff1ae19	operations: add abort on exit to multithread copy	2023-08-24 12:39:27 +01:00

Nick Craig-Wood	0d0bcdac31	fs: add context.Ctx to ChunkWriter methods ... WriteChunk in particular needs a different context from that which OpenChunkWriter was used with so add it to all the methods.	2023-08-24 12:39:27 +01:00
Nick Craig-Wood	f3bd02f0ef	operations: fix and tidy multithread code ... - fix docs and error messages for multithread - use sync/errgroup built in concurrency limiting - re-arrange multithread code - don't continue multi-thread uploads if one part fails	2023-08-24 12:39:27 +01:00
Nick Craig-Wood	b4e3332e02	fs: introduces aliases for OpenWriterAtFn and OpenChunkWriterFn	2023-08-24 12:39:27 +01:00
Vitor Gomes	181fecaec3	multithread: refactor multithread operation to use OpenChunkWriter if available #7056 ... If the feature OpenChunkWriter is not available, multithread tries to create an adapter from OpenWriterAt to OpenChunkWriter.	2023-08-12 17:55:01 +01:00
Paulo Schreiner	fcb912a664	fs: allow setting a write buffer for multithread ... when multi-thread downloading is enabled, rclone used to send a write to disk after every read, resulting in a lot of small writes to different locations of the file. depending on the underlying filesystem or device, it can be more efficient to send bigger writes.	2023-06-23 18:44:43 +01:00
Nick Craig-Wood	1f9c962183	operations: reopen downloads on error when using check --download and cat ... Before this change, some parts of operations called the Open method on objects directly, and some called NewReOpen to make an object which can re-open itself on errors. This adds a new function operations.Open which should be called instead of fs.Object.Open to open a reliable stream of data and changes all call sites to use that. This means `rclone check --download` and `rclone cat` will re-open files on failures.

Nick Craig-Wood	e43b5ce5e5	Remove github.com/pkg/errors and replace with std library version ... 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.	2021-11-07 11:53:30 +00:00
Nick Craig-Wood	2e21c58e6a	fs: deglobalise the config #4685 ... 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.	2020-11-26 16:40:12 +00:00

Nick Craig-Wood	421585dd72	accounting: add context to Account and propagate changes #3257 ... 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.	2020-07-28 16:41:17 +01:00

Nick Craig-Wood	bde0334bd8	operations: fix setting the timestamp on Windows for multithread copy ... Before this fix we attempted to set the modification time on the file when it was open. This works fine on Linux but not on Windows. The test was also incorrect testing the source file rather than the destination file. This closes the file before setting the modification time and fixes the tests. Fixes #3994	2020-02-24 17:30:09 +00:00

Aleksandar Jankovic	be0464f5f1	accounting: change stats interface ... This is done to make clear ownership over accounting object and prepare for removing global stats object. Stats elapsed time calculation has been altered to account for actual transfer time instead of stats creation time.	2019-07-28 14:48:19 +01:00

Aleksandar Jankovic	f78cd1e043	Add context propagation to rclone ... - Change rclone/fs interfaces to accept context.Context - Update interface implementations to use context.Context - Change top level usage to propagate context to lover level functions Context propagation is needed for stopping transfers and passing other request-scoped values.	2019-06-19 11:59:46 +01:00
Nick Craig-Wood	7d70e92664	operations: enable multi threaded downloads - Fixes #2252 ... This implements the --multi-thread-cutoff and --multi-thread-streams flags to control multi thread downloading to the local backend.	2019-05-11 23:35:19 +01:00
