2018-04-16pack-objects: use bitfield for object_entry::depthLibravatar Nguyễn Thái Ngọc Duy3-2/+7
Because of struct packing from now on we can only handle max depth 4095 (or even lower when new booleans are added in this struct). This should be ok since long delta chain will cause significant slow down anyway. Signed-off-by: Nguyễn Thái Ngọc Duy <pclouds@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2018-04-05git-svn: allow empty email-address using authors-prog and authors-fileLibravatar Andreas Heiduk1-3/+5
The email address in --authors-file and --authors-prog can be empty but git-svn translated it into a fictional email address in the form jondoe <jondoe@6aafaa21e0fb4338a68ab372a049893d> containing the SVN repository UUID. Now git-svn behaves like git-commit: If the email is *explicitly* set to the empty string using '<>', the commit does not contain an email address, only the name: jondoe <> Allowing to remove the email address *intentionally* prevents automatic systems from sending emails to those fictional addresses and avoids cluttering the log output with unnecessary stuff.

2018-04-05git-svn: search --authors-prog in PATH tooLibravatar Andreas Heiduk1-0/+5
In 36db1eddf9 ("git-svn: add --authors-prog option", 2009-05-14) the path to authors-prog was made absolute because git-svn changes the current directory in some situations. This makes sense if the program is part of the repository but prevents searching via $PATH. The old behaviour is still retained, but if the file does not exists, then authors-prog is searched for in $PATH as any other command.

2018-03-29upload-pack: disable object filtering when disabled by configLibravatar Jonathan Nieder1-1/+1
When upload-pack gained partial clone support (v2.17.0-rc0~132^2~12, 2017-12-08), it was guarded by the uploadpack.allowFilter config item to allow server operators to control when they start supporting it. That config item didn't go far enough, though: it controls whether the 'filter' capability is advertised, but if a (custom) client ignores the capability advertisement and passes a filter specification anyway, the server would handle that despite allowFilter being false. This is particularly significant if a security bug is discovered in this new experimental partial clone code. Installations without uploadpack.allowFilter ought not to be affected since they don't intend to support partial clone, but they would be swept up into being vulnerable. Simplify and limit the attack surface by making uploadpack.allowFilter disable the feature, not just the advertisement of it.

Add a tlsv1.3 option to http.sslVersion in addition to the existing tlsv1.[012] options. libcurl has supported this since 7.52.0.

Hotfix. * tg/stash-doc-typofix: git-stash.txt: remove extra square bracket
2018-03-27git-stash.txt: remove extra square bracketLibravatar Thomas Gummerer1-1/+1
In 1ada5020b3 ("stash: use stash_push for no verb form", 2017-02-28), when the pathspec argument was introduced in 'git stash', that was also documented. However I forgot to remove an extra square bracket after the '--message' argument, even though the square bracket should have been after the pathspec argument (where it was also added). Remove the extra square bracket after the '--message' argument, to show that the pathspec argument should be used with the 'push' verb. While the pathspec argument can be used without the push verb, that's a special case described later in the man page, and removing the first extra square bracket instead of the second one makes the synopis easier to understand.

2018-03-27doc hash-function-transition: clarify what SHAttered meansLibravatar Ævar Arnfjörð Bjarmason1-5/+24
Attempt to clarify what the SHAttered attack means in practice for Git. The previous version of the text made no mention whatsoever of Git already having a mitigation for this specific attack, which the SHAttered researchers claim will detect cryptanalytic collision attacks. I may have gotten some of the nuances wrong, but as far as I know this new text accurately summarizes the current situation with SHA-1 in git. I.e. git doesn't really use SHA-1 anymore, it uses Hardened-SHA-1 (they just so happen to produce the same outputs 99.99999999999...% of the time). Thus the previous text was incorrect in asserting that: [...]As a result [of SHAttered], SHA-1 cannot be considered cryptographically secure any more[...] That's not the case. We have a mitigation against SHAttered, *however* we consider it prudent to move to work towards a NewHash should future vulnerabilities in either SHA-1 or Hardened-SHA-1 emerge.

2018-03-20doc/gitattributes: mention non-recursive behaviorLibravatar Jeff King1-3/+10
The gitattributes documentation claims that the pattern rules are largely the same as for gitignore. However, the rules for recursion are different. In an ideal world, we would make them the same (if for nothing else than consistency and simplicity), but that would create backwards compatibility issues. For some discussion, see this thread: https://public-inbox.org/git/slrnkldd3g.1l4.jan@majutsushi.net/ But let's at least document the differences instead of actively misleading the user by claiming that they're the same.

2018-03-15worktree: delete dead codeLibravatar Nguyễn Thái Ngọc Duy1-5/+0
This "link" was a feature in early iterations of multiple worktree functionality for some reason it was dropped [1]. Since nobody creates this "link", there's no need to check it. This is mostly used to let the user moves a worktree manually [2]. If you move a worktree within the same file system, this hard link count lets us know the worktree is still there even if we don't know where it is. We support 'worktree move' now and don't need this anymore.
