2008-05-25Ignore no-op changes in paranoid update hookLibravatar Shawn O. Pearce1-0/+1
If the hook gets invoked with identical old and new ids there is no change taking place. We probably should not have been called, but instead of failing silently allow the no-op. Signed-off-by: Shawn O. Pearce <spearce@spearce.org> Signed-off-by: Junio C Hamano <gitster@pobox.com>

If a user or group ACL file does not exist in the current tip revision of the acl repository we will get an error from cat-file when we ask for that blob as it cannot be resolved. A quick look at the history by rev-list can tell us if there is a path there or not. Signed-off-by: Shawn O. Pearce <spearce@spearce.org> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2008-05-25Don't diff empty tree on branch creation in paranoid update hookLibravatar Shawn O. Pearce1-8/+6
Listing all files in a branch during branch creation is silly; the user's file-level ACLs probably don't mean anything at this point. We now treat the base case of 0{40} as an empty diff, as this happens only when the user is creating the branch and there are file level ACLs that diff against the old value of the branch.

2008-04-21post-receive-email: fix accidental removal of a trailing space in signature lineLibravatar Andy Parkins1-1/+2
post-receive-email adds a signature to the end of emails in generate_email_footer(). The signature was separated from the main email body using the standard string "-- ". (see RFC 3676) a6080a0 (War on whitespace, 2007-06-07) removed the trailing whitespace from "-- ", leaving it as "--", which is not a correct signature separator. This patch restores the missing space, but does it in a way that will not set off the trailing whitespace alarms.

2007-09-18Added example hook script to save/restore permissions/ownership.Libravatar Josh England1-0/+213
Usage info is emebed in the script, but the gist of it is to run the script from a pre-commit hook to save permissions/ownership data to a file and check that file into the repository. Then, a post_merge hook reads the file and updates working tree permissions/ownership. All updates are transparent to the user (although there is a --verbose option). Merge conflicts are handled in the "read" phase (in pre-commit), and the script aborts the commit and tells you how to fix things in the case of a merge conflict in the metadata file. This same idea could be extended to handle file ACLs or other file metadata if desired. Signed-off-by: Josh England <jjengla@sandia.gov> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2007-08-10Use the empty tree for base diff in paranoid-update on new branchesLibravatar Shawn O. Pearce1-10/+21
We have to load a tree difference for the purpose of testing file patterns. But if our branch is being created and there is no specific base to difference against in the rule our base will be '0'x40. This is (usually) not a valid tree-ish object in a Git repository, so there's nothing to difference against. Instead of creating the empty tree and running git-diff against that we just take the output of `ls-tree -r --name-only` and mark every returned pathname as an add. Signed-off-by: Shawn O.

2007-08-10Teach the update-paranoid to look at file differencesLibravatar Shawn O. Pearce1-7/+105
In some applications of the update hook a user may be allowed to modify a branch, but only if the file level difference is also an allowed change. This is the commonly requested feature of allowing users to modify only certain files. A new repository.*.allow syntax permits granting the three basic file level operations: A: file is added relative to the other tree M: file exists in both trees, but its SHA-1 or mode differs D: file is removed relative to the other tree on a per-branch and path-name basis. The user must also have a branch level allow line already granting them access to create, rewind or update (CRU) that branch before the hook will consult any file level rules. In order for a branch change to succeed _all_ files that differ relative to some base (by default the old value of this branch, but it can also be any valid tree-ish) must be allowed by file level allow rules. A push is rejected if any diff exists that is not covered by at least one allow rule. Signed-off-by: Shawn O. Pearce <spearce@spearce.org> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2007-08-10Teach update-paranoid how to store ACLs organized by groupsLibravatar Shawn O. Pearce1-16/+44
In some applications of this paranoid update hook the set of ACL rules that need to be applied to a user can be large, and the number of users that those rules must also be applied to can be more than a handful of individuals. Rather than repeating the same rules multiple times (once for each user) we now allow users to be members of groups, where the group supplies the list of ACL rules. For various reasons we don't depend on the underlying OS groups and instead perform our own group handling. Users can be made a member of one or more groups by setting the user.memberOf property within the "users/$who.acl" file: [user] memberOf = developer memberOf = administrator This will cause the hook to also parse the "groups/$groupname.acl" file for each value of user.memberOf, and merge any allow rules that match the current repository with the user's own private rules (if they had any). Since some rules are basically the same but may have a component differ based on the individual user, any user.* key may be inserted into a rule using the "${user.foo}" syntax. The allow rule does not match if the user does not define one (and exactly one) value for the key "foo". Signed-off-by: Shawn O.

The sed command that extracted the first line of the project description didn't include the -n switch and hence the project name was being printed twice. This was ruining the email header generation because it was assumed that the description was only one line and was included in the subject.

2007-04-19Contribute a fairly paranoid update hookLibravatar Shawn O. Pearce1-0/+284
I'm using a variant of this update hook in a corporate environment where we perform some validations of the commits and tags that are being pushed. The model is a "central repository" type setup, where users are given access to push to specific branches within the shared central repository. In this particular installation we run a specially patched git-receive-pack in setuid mode via SSH, allowing all writes into the repository as the repository owner, but only if this hook blesses it. One of the major checks we perform with this hook is that the 'committer' line of a commit, or the 'tagger' line of a new annotated tag actually correlates to the UNIX user who is performing the push. Users can falsify these lines on their local repositories, but the central repository that management trusts will reject all such forgery attempts. Of course 'author' lines are still allowed to be any value, as sometimes changes do come from other individuals. Another nice feature of this hook is the access control lists for all repositories on the system can also be stored and tracked in a supporting Git repository, which can also be access controlled by itself. This allows full auditing of who-had-what-when-and-why, thanks to git-blame's data mining capabilities. Signed-off-by: Shawn O.

2007-03-31Reimplement emailing part of hooks--update in contrib/hooks/post-receive-emailLibravatar Andy Parkins1-0/+588
The update hook is no longer the correct place to generate emails; there is now the hooks/post-receive script which is run automatically after a ref has been updated. This patch is to make use of that new location, and to address some faults in the old update hook. The primary problem in the conversion was that in the update hook, the ref has not actually been changed, but is about to be. In the post-receive hook the ref has already been updated. That meant that where we previously had lines like: git rev-list --not --all would now give the wrong list because "--all" in the post-receive hook includes the ref that we are making the email for. This made it more difficult to show only the new revisions added by this update. The solution is not pretty; however it does work and doesn't need any changes to git-rev-list itself. It also fixes (more accurately: reduces the likelihood of) a nasty race when another update occurs while this script is running. The solution, in short, looks like this (see the source code for a longer explanation) git rev-parse --not --all | grep -v $(git rev-parse $refname) | git rev-list --pretty --stdin $oldrev..$newrev This uses git-rev-parse followed by grep to filter out the revision of the ref in question before it gets to rev-list and inhibits the output of itself. By using $(git rev-parse $revname) rather than $newrev as the filter, it also takes care of the situation where another update to the same ref has been made since $refname was $newrev. The second problem that is addressed is that of tags inhibiting the correct output of an update email. Consider this, with somebranch and sometag pointing at the same revision: git push origin somebranch git push origin sometag That would work fine; the push of the branch would generate an email containing all the new commits introduced by the update, then the push of the tag would generate the shortlog formatted tag email. Now consider: git push origin sometag git push origin somebranch When some branch comes to run its "--not --all" line, it will find sometag, and filter those commits from the email - leaving nothing. That meant that those commits would not show (in full) on any email. The fix is to not use "--all", and instead use "--branches" in the git-rev-parse command. Other changes * Lose the monstrous one-giant-script layout and put things in easy to digest functions. This makes it much easier to find the place you need to change if you wanted to customise the output. I've also tried to write more verbose comments for the same reason. The hook script is big, mainly because of all the different cases that it has to handle, so being easy to navigate is important. * All uses of "git-command" changed to "git command", to cope better if a user decided not to install all the hard links to git; * Cleaned up some of the English in the email * The fact that the receive hook makes the ref available also allows me to use Shawn Pearce's fantastic suggestion that an annotated tag can be parsed with git-for-each-ref. This removes the potentially non-portable use of "<<<" heredocs and the nasty messing around with "date" to convert numbers of seconds UTC to a real date * Deletions are now caught and notified (briefly) * To help with debugging, I've retained the command line mode from the update hook; but made it so that the output is not emailed, it's just printed to the screen. This could then be redirected if the user wanted * Removed the "Hello" from the beginning of the email - it's just noise, and no one seriously has their day made happier by "friendly" programs * The fact that it doesn't rely on repository state as an indicator any more means that it's far more stable in its output; hopefully the same arguments will always generate the same email - even if the repository changes in the future. This means you can easily recreate an email should you want to. * Included Jim Meyering's envelope sender option for the sendmail call * The hook is now so big that it was inappropriate to copy it to every repository by keeping it in the templates directory. Instead, I've put a comment saying to look in contrib/hooks, and given an example of calling the script from that template hook. The advantage of calling the script residing at some fixed location is that if a future package of git included a bug fixed version of the script, that would be picked up automatically, and the user would not have to notice and manually copy the new hook to every repository that uses it.
