From 576dd8594f00d519d2906f0fab7f8c717726580e Mon Sep 17 00:00:00 2001 From: chamilton-ccn Date: Mon, 1 Jun 2026 16:33:53 -0400 Subject: [PATCH 1/8] This commit adds two parameters: `--data-transfer-limit` and `--delay-transfer-limit-check`. The former sets a limit on the amount of data to be transferred (does not account for delta transfer), and the latter allows the limit to be exceeded in cases where the limit has not yet been reached, but the next file will exceed it. For example, if the limit is 100MiB and 99MiB have transferred, and the next file is 10MiB, the delay parameter will allow that file to be transferred. In this example, without the delay parameter, rsync will stop at 99MiB. --- flist.c | 41 +++++++++++++++++++++++++++++++++++++++++ generator.c | 49 ++++++++++++++++++++++++++++++++++++++++++++----- io.c | 8 ++++++++ options.c | 29 +++++++++++++++++++++++++++++ rsync.h | 3 +++ 5 files changed, 125 insertions(+), 5 deletions(-) diff --git a/flist.c b/flist.c index 2ec07f54a..72448674f 100644 --- a/flist.c +++ b/flist.c @@ -78,6 +78,7 @@ extern uid_t our_uid;
