db5360f3 (name-hash: refactor polymorphic index_name_exists(); 2013-09-17) split index_name_exists() into index_file_exists() and index_dir_exists() but retained index_name_exists() as a thin wrapper to avoid disturbing possible in-flight topics. Since this change landed in 'master' some time ago and there are no in-flight topics referencing index_name_exists(), retire it.

When --mixed is used, entries could be removed from index if the target ref does not have them. When "reset" is used in preparation for commit spliting (in a dirty worktree), it could be hard to track what files to be added back. The new option --intent-to-add simplifies it by marking all removed files intent-to-add. Signed-off-by: NNguyễn Thái Ngọc Duy <pclouds@gmail.com>

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 dd621df9 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.

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.

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.

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.

The said function has this signature: extern int checkout_entry(struct cache_entry *ce, const struct checkout *state, char *topath); At first glance, it might appear that the caller of checkout_entry() can specify to which path the contents are written out by the last parameter, and it is tempting to add "const" in front of its type. In reality, however, topath[] is to point at a buffer to store the temporary path generated by the callchain originating from this function, and the temporary path is always short, much shorter than the buffer prepared by its only caller in builtin/checkout-index.c. Document the code a bit to clarify so that future callers know how to use the function better. Noticed-by: NNguyễn Thái Ngọc Duy <pclouds@gmail.com> Signed-off-by: NJunio C Hamano <gitster@pobox.com>

Using a relative_path as git_dir first appears in v1.5.6-1-g044bbbcb. It will make git_dir shorter only if git_dir is inside work_tree, and this will increase performance. But my last refactor effort on relative_path function (commit v1.8.3-rc2-12-ge02ca72f) changed that. Always use relative_path as git_dir may bring troubles like $gmane/234434. Because new relative_path is a combination of original relative_path from path.c and original path_relative from quote.c, so in order to restore the origin implementation, save the original relative_path as remove_leading_path, and call it in setup.c.

Commit a9080475 taught format-patch the "--from" option, which places the author ident into an in-body from header, and uses the committer ident in the rfc822 from header. The documentation claims that it will omit the in-body header when it is the same as the rfc822 header, but the code never implemented that behavior. This patch completes the feature by comparing the two idents and doing nothing when they are the same (this is the same as simply omitting the in-body header, as the two are by definition indistinguishable in this case). This makes it reasonable to turn on "--from" all the time (if it matches your particular workflow), rather than only using it when exporting other people's patches.

Depending upon the absence or presence of a trailing '/' on the incoming pathname, index_name_exists() checks either if a file is present in the index or if a directory is represented within the index. Each caller explicitly chooses the mode of operation by adding or removing a trailing '/' before invoking index_name_exists(). Since these two modes of operations are disjoint and have no code in common (one searches index_state.name_hash; the other dir_hash), they can be represented more naturally as distinct functions: one to search for a file, and one for a directory. Splitting index searching into two functions relieves callers of the artificial burden of having to add or remove a slash to select the mode of operation; instead they just call the desired function. A subsequent patch will take advantage of this benefit in order to eliminate the requirement that the incoming pathname for a directory search must have a trailing slash. (In order to avoid disturbing in-flight topics, index_name_exists() is retained as a thin wrapper dispatching either to index_dir_exists() or index_file_exists().)

When you run "git config --int", the maximum size of integer you get depends on how git was compiled, and what it considers to be an "int". This is almost useful, because your scripts calling "git config" will behave similarly to git internally. But relying on this is dubious; you have to actually know how git treats each value internally (e.g., int versus unsigned long), which is not documented and is subject to change. And even if you know it is "unsigned long", we do not have a git-config option to match that behavior. Furthermore, you may simply be asking git to store a value on your behalf (e.g., configuration for a hook). In that case, the relevant range check has nothing at all to do with git, but rather with whatever scripting tools you are using (and git has no way of knowing what the appropriate range is there). Not only is the range check useless, but it is actively harmful, as there is no way at all for scripts to look at config variables with large values. For instance, one cannot reliably get the value of pack.packSizeLimit via git-config. On an LP64 system, git happily uses a 64-bit "unsigned long" internally to represent the value, but the script cannot read any value over 2G. Ideally, the "--int" option would simply represent an arbitrarily large integer. For practical purposes, however, a 64-bit integer is large enough, and is much easier to implement (and if somebody overflows it, we will still notice the problem, and not simply return garbage).

:(glob)path differs from plain pathspec that it uses wildmatch with WM_PATHNAME while the other uses fnmatch without FNM_PATHNAME. The difference lies in how '*' (and '**') is processed. With the introduction of :(glob) and :(literal) and their global options --[no]glob-pathspecs, the user can: - make everything literal by default via --noglob-pathspecs --literal-pathspecs cannot be used for this purpose as it disables _all_ pathspec magic. - individually turn on globbing with :(glob) - make everything globbing by default via --glob-pathspecs - individually turn off globbing with :(literal) The implication behind this is, there is no way to gain the default matching behavior (i.e. fnmatch without FNM_PATHNAME). You either get new globbing or literal. The old fnmatch behavior is considered deprecated and discouraged to use.

Each caller of sha1_object_info_extended sets up an object_info struct to tell the function which elements of the object it wants to get. Until now, getting the type of the object has always been required (and it is returned via the return type rather than a pointer in object_info). This can involve actually opening a loose object file to determine its type, or following delta chains to determine a packed file's base type. These effects produce a measurable slow-down when doing a "cat-file --batch-check" that does not include %(objecttype). This patch adds a "typep" query to struct object_info, so that it can be optionally queried just like size and disk_size. As a result, the return type of the function is no longer the object type, but rather 0/-1 for success/error. As there are only three callers total, we just fix up each caller rather than keep a compatibility wrapper: 1. The simpler sha1_object_info wrapper continues to always ask for and return the type field. 2. The istream_source function wants to know the type, and so always asks for it. 3. The cat-file batch code asks for the type only when %(objecttype) is part of the format string. On linux.git, the best-of-five for running: $ git rev-list --objects --all >objects $ time git cat-file --batch-check='%(objectsize:disk)' on a fully packed repository goes from: real 0m8.680s user 0m8.160s sys 0m0.512s to: real 0m7.205s user 0m6.580s sys 0m0.608s Signed-off-by: NJeff King <peff@peff.net> Signed-off-by: NJunio C Hamano <gitster@pobox.com>
