Well, cgit-beta did not have had all these tags if i recall correctly, did it? I mean it has been two months or so since i last had it because "git fetch" bailed here due to the errors that i have reported, and fetching more than a gigabyte for brand-new fetches devastates here. But i _think_ all the tags below refs/tags/vendor/ like vendor/wpa/2.9 vendor/wpa_supplicant/0.3.8 vendor/wpa_supplicant/0.5.10 vendor/wpa_supplicant/0.5.11 vendor/x86emu/4.6 vendor/xe/1.13 etc. did not exist in cgit-beta? I surely would have said something once comments have been requested, wouldn't i? The thing is if i do #?0|kent:free-src.git$ git ls-remote|wc -l From https://git.freebsd.org/src.git 6814 This is a tremendous amount of head references that need to be compared. #?0|kent:free-src.git$ cd ../net-src.git/ #?0|kent:net-src.git$ git ls-remote|wc -l From https://github.com/NetBSD/src.git 609 #?0|kent:net-src.git$ cd ../open-src.git/ #?0|kent:open-src.git$ git ls-remote|wc -l From https://github.com/openbsd/src.git 34 #?0|kent:open-src.git$ cd ../dfly-src.git/ #?0|kent:dfly-src.git$ git ls-remote|wc -l From git://git.dragonflybsd.org/dragonfly.git 349 Linux is a little bit more #?0|kent:linux.git$ git ls-remote|wc -l From https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/ 7019 but this specific repository tracks all release candidates and all the update releases, which alone go into the hundreds. Anyhow, the difference is the number of local references that effectively have to be compared against remote heads. For example my local Linux repo is this: [remote "origin"] url = https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/ fetch = +refs/heads/linux-4.19.y:refs/remotes/origin/linux-4.19.y fetch = +refs/heads/linux-5.10.y:refs/remotes/origin/linux-5.10.y fetch = +refs/heads/master:refs/remotes/origin/master And if i "sr" (show-ref) i get: #?0|kent:linux.git$ git sr|wc -l 925 which is a lot due to Linux update policy, but it only relates to the project itself, there is not one reference of what is effectively vendor data like for example Merge tag 'wireless-drivers-next-2020-12-12' of git://git.kernel.org/pub/scm/linux/kernel/git/kvalo/wireless-drivers-next may it be in refs/tags or anywhere else, whereas with FreeBSD and [remote "origin"] url = https://git.freebsd.org/src.git fetch = +refs/heads/releng/5.5:refs/remotes/origin/releng/5.5 fetch = +refs/heads/releng/6.4:refs/remotes/origin/releng/6.4 fetch = +refs/heads/releng/7.4:refs/remotes/origin/releng/7.4 fetch = +refs/heads/releng/8.4:refs/remotes/origin/releng/8.4 fetch = +refs/heads/releng/9.3:refs/remotes/origin/releng/9.3 fetch = +refs/heads/releng/10.3:refs/remotes/origin/releng/10.4 fetch = +refs/heads/releng/11.4:refs/remotes/origin/releng/11.4 fetch = +refs/heads/releng/12.2:refs/remotes/origin/releng/12.2 fetch = +refs/heads/stable/12:refs/remotes/origin/stable/12 fetch = +refs/heads/main:refs/remotes/origin/main there is #?0|kent:free-src.git$ git sr|wc -l 2137 but if i go for "the real" FreeBSD itself it is just #?0|kent:free-src.git$ git sr | grep -v vendor | wc -l 19 namely a62107ed19a1095158f454132a3b6ec536a4de7c refs/remotes/origin/main 8411c9ac24aabdbbde468778b35da58dc3c15178 refs/remotes/origin/releng/10.4 4adbf1f6686ffdc4c0555a018e14ec63b5981534 refs/remotes/origin/releng/11.4 2120d07af09cb830873554ba5405c5d3e51b41cc refs/remotes/origin/releng/12.2 d4c364b3dcf6dfe4e20c70d31912aad7e6219c14 refs/remotes/origin/releng/5.5 0df48150179039ce25e09b48c85aa39bffdbb4c4 refs/remotes/origin/releng/6.4 1c7fe7463d0204f08806b9da6d5d50fb7f75c5ad refs/remotes/origin/releng/7.4 554a1309dbd71bb59ed4e97ea5e0bc829dad0f04 refs/remotes/origin/releng/8.4 b06b7e647fe7b4eefbd29369cf0c24e1902bf72a refs/remotes/origin/releng/9.3 f4d0bc6aa6b90cbb0ea6cb993d9a10e36f5f4a4c refs/remotes/origin/stable/12 aed278eb8da79777d64e06bbc94ee0a018885477 refs/tags/release/10.3.0 20dbcb9a99d5c4b8ceb4897f27c53ab9fb853167 refs/tags/release/11.4.0 906434f95e83f03e0ac62d2544dad1656b5df1e9 refs/tags/release/12.2.0 1185954e6d623ada4ef32f25687ecd5e5c003545 refs/tags/release/5.5.0 44b4768239e96f6d6ba8a43cb2542e1bc83dec94 refs/tags/release/6.4.0 c31c07d1a9283bd28bb00ce519dfca69e529f452 refs/tags/release/7.4.0 174c77559c8cc317c743876f55f02bec233735f4 refs/tags/release/8.1.0 45cf4d6a59488ea4113bde749bb61de33882cc46 refs/tags/release/8.4.0 1fb916120b12fdc14c7f93aa5f14849db0efa166 refs/tags/release/9.3.0 and thus #?0|kent:free-src.git$ git sr | grep vendor | wc -l 2118 Which is a pity since all these references will be checked during "git fetch" unless i am mistaken. |>repository, but you decided to loose one of the strengts of git, |>selective tracking.
