* support globbing/wildcards on windows
* add `osc 9;4` to show upload progress in the taskbar
(currently windows-only; linux is picking it up)
* workaround msys2-terminal not normalizing
absolute paths which contain whitespace
* show a helpful "now hashing..." while the
first file is being hashed, since it kinda
looks like a deadlock on windows otherwise
previously, the biggest file that could be uploaded through
cloudflare was 383 GiB, due to max num chunks being 4096
`--u2sz`, which takes three ints (min-size, target, max-size)
can now be used to enforce a max chunksize; chunks larger
than max-size gets split into smaller subchunks / chunklets
subchunks cannot be stitched/joined, and subchunks of the
same chunk must be uploaded sequentially, one at a time
if a subchunk fails due to bitflips or connection-loss,
then the entire chunk must (and will) be reuploaded
newlines, invalid utf8, and worst of all... %20 (whitespace)
due to up2k protocol limitations,
filenames are normalized when they hit the server,
but folders get to keep their intended jank
previous approach:
* cache 64K on first read
* cache 1M on subsequent intersecting reads
new approach:
* cache 64K on first read
* cache 1M on the next intersecting read
* cache 8M on subsequent intersecting reads
* cache 4M on standalone reads at offsets >1M
improves performance by 50% on windows
and should help on high-latency connections
* wark landed in the wrong registry when moved to another volume
(harmless; upload would succeed on the next handshake)
* dedup did not apply correctly when moved into another volume,
since all the checks were done based on the previous vol;
fix this by recursing the whole thing
also update the reloc example after some real-world experience
Reported-by: @daniiooo
hooks can now interrupt or redirect actions, and initiate
related actions, by printing json on stdout with commands
mainly to mitigate limitations such as sharex/sharex#3992
xbr/xau can redirect uploads to other destinations with `reloc`
and most hooks can initiate indexing or deletion of additional
files by giving a list of vpaths in json-keys `idx` or `del`
there are limitations;
* xbu/xau effects don't apply to ftp, tftp, smb
* xau will intentionally fail if a reloc destination exists
* xau effects do not apply to up2k
also provides more details for hooks:
* xbu/xau: basic-uploader vpath with filename
* xbr/xar: add client ip
v1.13.5 made some proxies angry with its massive chunklists
when stitching chunks, only list the first chunk hash in full,
and include a truncated hash for the consecutive chunks
should be enough for logfiles to make sense
and to smoketest that clients are behaving
rather than sending each file chunk as a separate HTTP request,
sibling chunks will now be fused together into larger HTTP POSTs
which results in unreasonably huge speed boosts on some routes
( `2.6x` from Norway to US-East, `1.6x` from US-West to Finland )
the `x-up2k-hash` request header now takes a comma-separated list
of chunk hashes, which must all be sibling chunks, resulting in
one large consecutive range of file data as the post body
a new global-option `--u2sz`, default `1,64,96`, sets the target
request size as 64 MiB, allowing the settings ui to specify any
value between 1 and 96 MiB, which is cloudflare's max value
this does not cause any issues for resumable uploads; thanks to the
streaming HTTP POST parser, each chunk will be verified and written
to disk as they arrive, meaning only the untransmitted chunks will
have to be resent in the event of a connection drop -- of course
assuming there are no misconfigured WAFs or caching-proxies
the previous up2k approach of uploading each chunk in a separate HTTP
POST was inefficient in many real-world scenarios, mainly due to TCP
window-scaling behaving erratically in some IXPs / along some routes
a particular link from Norway to Virginia,US is unusably slow for
the first 4 MiB, only reaching optimal speeds after 100 MiB, and
then immediately resets the scale when the request has been sent;
connection reuse does not help in this case
on this route, the basic-uploader was somehow faster than up2k
with 6 parallel uploads; only time i've seen this
