2014-02-24date: check date overflow against time_tLibravatar Jeff King1-0/+1
When we check whether a timestamp has overflowed, we check only against ULONG_MAX, meaning that strtoul has overflowed. However, we also feed these timestamps to system functions like gmtime, which expect a time_t. On many systems, time_t is actually smaller than "unsigned long" (e.g., because it is signed), and we would overflow when using these functions. We don't know the actual size or signedness of time_t, but we can easily check for truncation with a simple assignment.

2014-01-14refname_match(): always use the rules in ref_rev_parse_rulesLibravatar Michael Haggerty1-3/+6
We used to use two separate rules for the normal ref resolution dwimming and dwimming done to decide which remote ref to grab. The third parameter to refname_match() selected which rules to use. When these two rules were harmonized in 2011-11-04 dd621df9cd refs DWIMmery: use the same rule for both "git fetch" and others , ref_fetch_rules was #defined to avoid potential breakages for in-flight topics. It is now safe to remove the backwards-compatibility code, so remove refname_match()'s third parameter, make ref_rev_parse_rules private to refs.c, and remove ref_fetch_rules entirely.

2014-01-06safe_create_leading_directories(): add new error value SCLD_VANISHEDLibravatar Michael Haggerty1-1/+9
Add a new possible error result that can be returned by safe_create_leading_directories() and safe_create_leading_directories_const(): SCLD_VANISHED. This value indicates that a file or directory on the path existed at one point (either it already existed or the function created it), but then it disappeared. This probably indicates that another process deleted the directory while we were working. If SCLD_VANISHED is returned, the caller might want to retry the function call, as there is a chance that a new attempt will succeed. Why doesn't safe_create_leading_directories() do the retrying internally? Because an empty directory isn't really ever safe until it holds a file. So even if safe_create_leading_directories() were absolutely sure that the directory existed before it returned, there would be no guarantee that the directory still existed when the caller tried to write something in it.

2013-12-26sha1_object_info_extended: provide delta base sha1sLibravatar Jeff King1-0/+1
A caller of sha1_object_info_extended technically has enough information to determine the base sha1 from the results of the call. It knows the pack, offset, and delta type of the object, which is sufficient to find the base. However, the functions to do so are not publicly available, and the code itself is intimate enough with the pack details that it should be abstracted away. We could add a public helper to allow callers to query the delta base separately, but it is simpler and slightly more efficient to optionally grab it along with the rest of the object_info data. For cases where the object is not stored as a delta, we write the null sha1 into the query field. A careful caller could check "oi.whence == OI_PACKED && oi.u.packed.is_delta" before looking at the base sha1, but using the null sha1 provides a simple alternative (and gives a better sanity check for a non-careful caller than simply returning random bytes).

This may be needed when a hook is run after a new shallow pack is received, but .git/shallow is not settled yet. A temporary shallow file to plug all loose ends should be used instead. GIT_SHALLOW_FILE is overriden by --shallow-file. --shallow-file does not work in this case because the hook may spawn many git subprocesses and the launch commands do not have --shallow-file as it's a recent addition.

2013-12-10shallow.c: the 8 steps to select new commits for .git/shallowLibravatar Nguyễn Thái Ngọc Duy1-0/+2
Suppose a fetch or push is requested between two shallow repositories (with no history deepening or shortening). A pack that contains necessary objects is transferred over together with .git/shallow of the sender. The receiver has to determine whether it needs to update .git/shallow if new refs needs new shallow comits. The rule here is avoid updating .git/shallow by default. But we don't want to waste the received pack. If the pack contains two refs, one needs new shallow commits installed in .git/shallow and one does not, we keep the latter and reject/warn about the former. Even if .git/shallow update is allowed, we only add shallow commits strictly necessary for the former ref (remember the sender can send more shallow commits than necessary) and pay attention not to accidentally cut the receiver history short (no history shortening is asked for) So the steps to figure out what ref need what new shallow commits are: 1. Split the sender shallow commit list into "ours" and "theirs" list by has_sha1_file. Those that exist in current repo in "ours", the remaining in "theirs". 2. Check the receiver .git/shallow, remove from "ours" the ones that also exist in .git/shallow. 3. Fetch the new pack. Either install or unpack it. 4. Do has_sha1_file on "theirs" list again. Drop the ones that fail has_sha1_file. Obviously the new pack does not need them. 5. If the pack is kept, remove from "ours" the ones that do not exist in the new pack. 6. Walk the new refs to answer the question "what shallow commits, both ours and theirs, are required in .git/shallow in order to add this ref?". Shallow commits not associated to any refs are removed from their respective list. 7. (*) Check reachability (from the current refs) of all remaining commits in "ours". Those reachable are removed. We do not want to cut any part of our (reachable) history. We only check up commits. True reachability test is done by check_everything_connected() at the end as usual. 8. Combine the final "ours" and "theirs" and add them all to .git/shallow. Install new refs. The case where some hook rejects some refs on a push is explained in more detail in the push patches. Of these steps, #6 and #7 are expensive. Both require walking through some commits, or in the worst case all commits. And we rather avoid them in at least common case, where the transferred pack does not contain any shallow commits that the sender advertises. Let's look at each scenario: 1) the sender has longer history than the receiver All shallow commits from the sender will be put into "theirs" list at step 1 because none of them exists in current repo. In the common case, "theirs" becomes empty at step 4 and exit early. 2) the sender has shorter history than the receiver All shallow commits from the sender are likely in "ours" list at step 1. In the common case, if the new pack is kept, we could empty "ours" and exit early at step 5. If the pack is not kept, we hit the expensive step 6 then exit after "ours" is emptied. There'll be only a handful of objects to walk in fast-forward case. If it's forced update, we may need to walk to the bottom. 3) the sender has same .git/shallow as the receiver This is similar to case 2 except that "ours" should be emptied at step 2 and exit early. A fetch after "clone --depth=X" is case 1. A fetch after "clone" (from a shallow repo) is case 3. Luckily they're cheap for the common case. A push from "clone --depth=X" falls into case 2, which is expensive. Some more work may be done at the sender/client side to avoid more work on the server side: if the transferred pack does not contain any shallow commits, send-pack should not send any shallow commits to the receive-pack, effectively turning it into a normal push and avoid all steps. This patch implements all steps except #3, already handled by fetch-pack and receive-pack, #6 and #7, which has their own patch due to their size. (*) in previous versions step 7 was put before step 3. I reorder it so that the common case that keeps the pack does not need to walk commits at all. In future if we implement faster commit reachability check (maybe with the help of pack bitmaps or commit cache), step 7 could become cheap and be moved up before 6 again.

One long-standing flaw in the pack transfer protocol used by "git clone" was that there was no way to tell the other end which branch "HEAD" points at, and the receiving end needed to guess.

2013-10-28cache: remove unused function 'have_git_dir'Libravatar Stefan Beller1-1/+0
This function was added in d2b0708 (2008-09-27, add have_git_dir() function) as a preparation for adbc0b6 (2008-09-30, cygwin: Use native Win32 API for stat). However the second referenced commit was reverted in f66450a (2013-06-22, cygwin: Remove the Win32 l/stat() implementation), so we don't need to expose this wrapper function any more as a public API.
