"git clone --resurse-submodules --reference $path $URL" is a way to reduce network transfer cost by borrowing objects in an existing $path repository when cloning the superproject from $URL; it learned to also peek into $path for presense of corresponding repositories of submodules and borrow objects from there when able. * sb/submodule-clone-rr: clone: recursive and reference option triggers submodule alternates clone: implement optional references clone: clarify option_reference as required clone: factor out checking for an alternate path submodule--helper update-clone: allow multiple references submodule--helper module-clone: allow multiple references t7408: merge short tests, factor out testing method t7408: modernize style

2016-09-08Merge branch 'bw/mingw-avoid-inheriting-fd-to-lockfile' into maintJunio C Hamano6-1/+35
The tempfile (hence its user lockfile) API lets the caller to open a file descriptor to a temporary file, write into it and then finalize it by first closing the filehandle and then either removing or renaming the temporary file. When the process spawns a subprocess after obtaining the file descriptor, and if the subprocess has not exited when the attempt to remove or rename is made, the last step fails on Windows, because the subprocess has the file descriptor still open. Open tempfile with O_CLOEXEC flag to avoid this (on Windows, this is mapped to O_NOINHERIT). * bw/mingw-avoid-inheriting-fd-to-lockfile: mingw: ensure temporary file handles are not inherited by child processes t6026-merge-attr: child processes must not inherit index.lock handles

"git difftool" by default ignores the error exit from the backend commands it spawns, because often they signal that they found differences by exiting with a non-zero status code just like "diff" does; the exit status codes 126 and above however are special in that they are used to signal that the command is not executable, does not exist, or killed by a signal.

2016-08-31diff: teach diff to display submodule difference with an inline diffJacob Keller7-21/+863
Teach git-diff and friends a new format for displaying the difference of a submodule. The new format is an inline diff of the contents of the submodule between the commit range of the update.

2016-08-31submodule: refactor show_submodule_summary with helper functionJacob Keller1-33/+82
A future patch is going to add a new submodule diff format which displays an inline diff of the submodule changes. To make this easier, and to ensure that both submodule diff formats use the same initial header, factor out show_submodule_header() function which will print the current submodule header line, and then leave the show_submodule_summary function to lookup and print the submodule log format. This does create one format change in that "(revision walker failed)" will now be displayed on its own line rather than as part of the message because we no longer perform this step directly in the header display flow. However, this is a rare case as most causes of the failure will be due to a missing commit which we already check for and avoid previously. flow. However, this is a rare case and shouldn't impact much. Signed-off-by: Jacob Keller <jacob.keller@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2016-08-31allow do_submodule_path to work even if submodule isn't checked outJacob Keller5-11/+173
Currently, do_submodule_path will attempt locating the .git directory by using read_gitfile on <path>/.git. If this fails it just assumes the <path>/.git is actually a git directory. This is good because it allows for handling submodules which were cloned in a regular manner first before being added to the superproject. Unfortunately this fails if the <path> is not actually checked out any longer, such as by removing the directory. Fix this by checking if the directory we found is actually a gitdir. In the case it is not, attempt to lookup the submodule configuration and find the name of where it is stored in the .git/modules/ directory of the superproject. If we can't locate the submodule configuration, this might occur because for example a submodule gitlink was added but the corresponding .gitmodules file was not properly updated. A die() here would not be pleasant to the users of submodule diff formats, so instead, modify do_submodule_path() to return an error code: - git_pathdup_submodule() returns NULL when we fail to find a path. - strbuf_git_path_submodule() propagates the error code to the caller. Modify the callers of these functions to check the error code and fail properly. This ensures we don't attempt to use a bad path that doesn't match the corresponding submodule. Because this change fixes add_submodule_odb() to work even if the submodule is not checked out, update the wording of the submodule log diff format to correctly display that the submodule is "not initialized" instead of "not checked out" Add tests to ensure this change works as expected.

2016-08-31graph: add support for --line-prefix on all graph-aware outputJacob Keller11-80/+504
Add an extension to git-diff and git-log (and any other graph-aware displayable output) such that "--line-prefix=<string>" will print the additional line-prefix on every line of output. To make this work, we have to fix a few bugs in the graph API that force graph_show_commit_msg to be used only when you have a valid graph. Additionally, we extend the default_diff_output_prefix handler to work even when no graph is enabled. This is somewhat of a hack on top of the graph API, but I think it should be acceptable here. This will be used by a future extension of submodule display which displays the submodule diff as the actual diff between the pre and post commit in the submodule project. Add some tests for both git-log and git-diff to ensure that the prefix is honored correctly. Signed-off-by: Jacob Keller <jacob.keller@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2016-08-31diff.c: remove output_prefix_length fieldJunio C Hamano3-4/+1
"diff/log --stat" has a logic that determines the display columns available for the diffstat part of the output and apportions it for pathnames and diffstat graph automatically. 5e71a84a (Add output_prefix_length to diff_options, 2012-04-16) added the output_prefix_length field to diff_options structure to allow this logic to subtract the display columns used for the history graph part from the total "terminal width"; this matters when the "git log --graph -p" option is in use. The field must be set to the number of display columns needed to show the output from the output_prefix() callback, which is error prone. As there is only one user of the field, and the user has the actual value of the prefix string, let's get rid of the field and have the user count the display width itself.

2016-08-31diff-highlight: avoid highlighting combined diffsJeff King2-1/+38
The algorithm in diff-highlight only understands how to look at two sides of a diff; it cannot correctly handle combined diffs with multiple preimages. Often highlighting does not trigger at all for these diffs because the line counts do not match up. E.g., if we see: - ours -theirs ++resolved we would not bother highlighting; it naively looks like a single line went away, and then a separate hunk added another single line. But of course there are exceptions. E.g., if the other side deleted the line, we might see: - ours ++resolved which looks like we dropped " ours" and added "+resolved". This is only a small highlighting glitch (we highlight the space and the "+" along with the content), but it's also the tip of the iceberg. Even if we learned to find the true content here (by noticing we are in a 3-way combined diff and marking _two_ characters from the front of the line as uninteresting), there are other more complicated cases where we really do need to handle a 3-way hunk. Let's just punt for now; we can recognize combined diffs by the presence of extra "@" symbols in the hunk header, and treat them as non-diff content.

Now that we have a test suite for diff highlight, we can show off the improvements from 8d00662 (diff-highlight: do not split multibyte characters, 2015-04-03). While we're at it, we can also add another case that _doesn't_ work: combining code points are treated as their own unit, which means that we may stick colors between them and the character they are modifying (with the result that the color is not shown in an xterm, though it's possible that other terminals err the other way, and show the color but not the accent). There's no fix here, but let's document it as a failure. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2016-08-29blame: fix segfault on untracked filesThomas Gummerer2-1/+7
Since 3b75ee9 ("blame: allow to blame paths freshly added to the index", 2016-07-16) git blame also looks at the index to determine if there is a file that was freshly added to the index. cache_name_pos returns -pos - 1 in case there is no match is found, or if the name matches, but the entry has a stage other than 0. As git blame should work for unmerged files, it uses strcmp to determine whether the name of the returned position matches, in which case the file exists, but is merely unmerged, or if the file actually doesn't exist in the index. If the repository is empty, or if the file would lexicographically be sorted as the last file in the repository, -cache_name_pos - 1 is outside of the length of the active_cache array, causing git blame to segfault. Guard against that, and die() normally to restore the old behaviour.

When the process spawns a subprocess after obtaining the file descriptor, and if the subprocess has not exited when the attempt to remove or rename is made, the last step fails on Windows, because the subprocess has the file descriptor still open.

2016-08-23delta_base_cache: use hashmap.hJeff King1-34/+60
The fundamental data structure of the delta base cache is a hash table mapping pairs of "(packfile, offset)" into structs containing the actual object data. The hash table implementation dates back to e5e0161 (Implement a simple delta_base cache, 2007-03-17), and uses a fixed-size table. The current size is a hard-coded 256 entries. Because we need to be able to remove objects from the hash table, entry lookup does not do any kind of probing to handle collisions. Colliding items simply replace whatever is in their slot. As a result, we have fewer usable slots than even the 256 we allocate. At half full, each new item has a 50% chance of displacing another one. Or another way to think about it: every item has a 1/256 chance of being ejected due to hash collision, without regard to our LRU strategy. So it would be interesting to see the effect of increasing the cache size on the runtime for some common operations. As with the previous patch, we'll measure "git log --raw" for tree-only operations, and "git log -Sfoo --raw" for operations that touch trees and blobs. All times are wall-clock best-of-3, done against fully packed repos with --depth=50, and the default core.deltaBaseCacheLimit of 96MB. Here are timings for various values of MAX_DELTA_CACHE against git.git (the asterisk marks the minimum time for each operation): MAX_DELTA_CACHE log-raw log-S --------------- --------- --------- 256 0m02.227s 0m12.821s 512 0m02.143s 0m10.602s 1024 0m02.127s 0m08.642s 2048 0m02.148s 0m07.123s 4096 0m02.194s 0m06.448s* 8192 0m02.239s 0m06.504s 16384 0m02.144s* 0m06.502s 32768 0m02.202s 0m06.622s 65536 0m02.230s 0m06.677s The log-raw case isn't changed much at all here (probably because our trees just aren't that big in the first place, or possibly because we have so _few_ trees in git.git that the 256-entry cache is enough). But once we start putting blobs in the cache, too, we see a big improvement (almost 50%). The curve levels off around 4096, which means that we can hold about that many entries before hitting the 96MB memory limit (or possibly that the workload is small enough that there is simply no more work to be optimized out by caching more). (As a side note, I initially timed my existing git.git pack, which was a base of --aggressive combined with some pulls on top. So it had quite a few deeper delta chains. The 256-cache case was more like 15s, and it still dropped to ~6.5s in the same way). Here are the timings for linux.git: MAX_DELTA_CACHE log-raw log-S --------------- --------- --------- 256 0m41.661s 5m12.410s 512 0m39.547s 5m07.920s 1024 0m37.054s 4m54.666s 2048 0m35.871s 4m41.194s* 4096 0m34.646s 4m51.648s 8192 0m33.881s 4m55.342s 16384 0m35.190s 5m00.122s 32768 0m35.060s 4m58.851s 65536 0m33.311s* 4m51.420s As we grow we see a nice 20% speedup in the tree traversal, and more modest 10% in the log-S. This is probably an indication that we are bound less by the number of entries, and more by the memory limit (more on that below). What is interesting is that the numbers bounce around a bit; increasing the number of entries isn't always a strict improvement. Partially this is due to noise in the measurement. But it may also be an indication that our LRU ejection scheme is not optimal. The smaller cache sizes introduce some randomness into the ejection (due to collisions), which may sometimes work in our favor (and sometimes not!). So what is the optimal setting of MAX_DELTA_CACHE? The "bouncing" in the linux.git log-S numbers notwithstanding, it mostly seems like bigger is better. And even if we were to try to find a "sweet spot", these are just two repositories, that are not necessarily representative. The shape of history, the size of trees and blobs, the memory limit configuration, etc, all will affect the outcome. Rather than trying to find the "right" number, another strategy is to just switch to a hash table that can actually store collisions: namely our hashmap.h implementation. Here are numbers for that compared to the "best" we saw from adjusting MAX_DELTA_CACHE: | log-raw | log-S | best hashmap | best hashmap | --------- --------- | --------- --------- git | 0m02.144s 0m02.144s | 0m06.448s 0m06.688s linux | 0m33.311s 0m33.092s | 4m41.194s 4m57.172s We can see the results are similar in most cases, which is what we'd expect. We're not ejecting due to collisions at all, so this is purely representing the LRU. So really, we'd expect this to model most closely the larger values of the static MAX_DELTA_CACHE limit. And that does seem to be what's happening, including the "bounce" in the linux log-S case. So while the value for that case _isn't_ as good as the optimal one measured above (which was 2048 entries), given the bouncing I'm hesitant to suggest that 2048 is any kind of optimum (not even for linux.git, let alone as a general rule). The generic hashmap has the appeal that it drops the number of tweakable numbers by one, which means we can focus on tuning other elements, like the LRU strategy or the core.deltaBaseCacheLimit setting. And indeed, if we bump the cache limit to 1G (which is probably silly for general use, but maybe something people with big workstations would want to do), the linux.git log-S time drops to 3m32s. That's something you really _can't_ do easily with the static hash table, because the number of entries needs to grow in proportion to the memory limit (so 2048 is almost certainly not going to be the right value there). This patch takes that direction, and drops the static hash table entirely in favor of using the hashmap.h API.

2016-08-23delta_base_cache: drop special treatment of blobsJeff King1-8/+0
When the delta base cache runs out of allowed memory, it has to drop entries. It does so by walking an LRU list, dropping objects until we are under the memory limit. But we actually walk the list twice: once to drop blobs, and then again to drop other objects (which are generally trees). This comes from 18bdec1 (Limit the size of the new delta_base_cache, 2007-03-19). This performs poorly as the number of entries grows, because any time dropping blobs does not satisfy the limit, we have to walk the _entire_ list, trees included, looking for blobs to drop, before starting to drop any trees. It's not generally a problem now, as the cache is limited to only 256 entries. But as we could benefit from increasing that in a future patch, it's worth looking at how it performs as the cache size grows. And the answer is "not well". The table below shows times for various operations with different values of MAX_DELTA_CACHE (which is not a run-time knob; I recompiled with -DMAX_DELTA_CACHE=$n for each). I chose "git log --raw" ("log-raw" in the table) because it will access all of the trees, but no blobs at all (so in a sense it is a worst case for this problem, because we will always walk over the entire list of trees once before realizing there are no blobs to drop). This is also representative of other tree-only operations like "rev-list --objects" and "git log -- <path>". I also timed "git log -Sfoo --raw" ("log-S" in the table). It similarly accesses all of the trees, but also the blobs for each commit. It's representative of "git log -p", though it emphasizes the cost of blob access more, as "-S" is cheaper than computing an actual blob diff. All timings are best-of-3 wall-clock times (though they all were CPU bound, so the user CPU times are similar). The repositories were fully packed with --depth=50, and the default core.deltaBaseCacheLimit of 96M was in effect. The current value of MAX_DELTA_CACHE is 256, so I started there and worked up by factors of 2. First, here are values for git.git (the asterisk signals the fastest run for each operation): MAX_DELTA_CACHE log-raw log-S --------------- --------- --------- 256 0m02.212s 0m12.634s 512 0m02.136s* 0m10.614s 1024 0m02.156s 0m08.614s 2048 0m02.208s 0m07.062s 4096 0m02.190s 0m06.484s* 8192 0m02.176s 0m07.635s 16384 0m02.913s 0m19.845s 32768 0m03.617s 1m05.507s 65536 0m04.031s 1m18.488s You can see that for the tree-only log-raw case, we don't actually benefit that much as the cache grows (all the differences up through 8192 are basically just noise; this is probably because we don't actually have that many distinct trees in git.git). But for log-S, we get a definite speed improvement as the cache grows, but the improvements are lost as cache size grows and the linear LRU management starts to dominate. Here's the same thing run against linux.git: MAX_DELTA_CACHE log-raw log-S --------------- --------- ---------- 256 0m40.987s 5m13.216s 512 0m37.949s 5m03.243s 1024 0m35.977s 4m50.580s 2048 0m33.855s 4m39.818s 4096 0m32.913s 4m47.299s* 8192 0m32.176s* 5m14.650s 16384 0m32.185s 6m31.625s 32768 0m38.056s 9m31.136s 65536 1m30.518s 17m38.549s The pattern is similar, though the effect in log-raw is more pronounced here. The times dip down in the middle, and then go back up as we keep growing. So we know there's a problem. What's the solution? The obvious one is to improve the data structure to avoid walking over tree entries during the looking-for-blobs traversal. We can do this by keeping _two_ LRU lists: one for blobs, and one for other objects. We drop items from the blob LRU first, and then from the tree LRU (if necessary). Here's git.git using that strategy: MAX_DELTA_CACHE log-raw log-S --------------- --------- ---------- 256 0m02.264s 0m12.830s 512 0m02.201s 0m10.771s 1024 0m02.181s 0m08.593s 2048 0m02.205s 0m07.116s 4096 0m02.158s 0m06.537s* 8192 0m02.213s 0m07.246s 16384 0m02.155s* 0m10.975s 32768 0m02.159s 0m16.047s 65536 0m02.181s 0m16.992s The upswing on log-raw is gone completely. But log-S still has it (albeit much better than without this strategy). Let's see what linux.git shows: MAX_DELTA_CACHE log-raw log-S --------------- --------- --------- 256 0m42.519s 5m14.654s 512 0m39.106s 5m04.708s 1024 0m36.802s 4m51.454s 2048 0m34.685s 4m39.378s* 4096 0m33.663s 4m44.047s 8192 0m33.157s 4m50.644s 16384 0m33.090s* 4m49.648s 32768 0m33.458s 4m53.371s 65536 0m33.563s 5m04.580s The results are similar. The tree-only case again performs well (not surprising; we're literally just dropping the one useless walk, and not otherwise changing the cache eviction strategy at all). But the log-S case again does a bit worse as the cache grows (though possibly that's within the noise, which is much larger for this case). Perhaps this is an indication that the "remove blobs first" strategy is not actually optimal. The intent of it is to avoid blowing out the tree cache when we see large blobs, but it also means we'll throw away useful, recent blobs in favor of older trees. Let's run the same numbers without caring about object type at all (i.e., one LRU list, and always evicting whatever is at the head, regardless of type). Here's git.git: MAX_DELTA_CACHE log-raw log-S --------------- --------- --------- 256 0m02.227s 0m12.821s 512 0m02.143s 0m10.602s 1024 0m02.127s 0m08.642s 2048 0m02.148s 0m07.123s 4096 0m02.194s 0m06.448s* 8192 0m02.239s 0m06.504s 16384 0m02.144s* 0m06.502s 32768 0m02.202s 0m06.622s 65536 0m02.230s 0m06.677s Much smoother; there's no dramatic upswing as we increase the cache size (some remains, though it's small enough that it's mostly run-to-run noise. E.g., in the log-raw case, note how 8192 is 50-100ms higher than its neighbors). Note also that we stop getting any real benefit for log-S after about 4096 entries; that number will depend on the size of the repository, the size of the blob entries, and the memory limit of the cache. Let's see what linux.git shows for the same strategy: MAX_DELTA_CACHE log-raw log-S --------------- --------- --------- 256 0m41.661s 5m12.410s 512 0m39.547s 5m07.920s 1024 0m37.054s 4m54.666s 2048 0m35.871s 4m41.194s* 4096 0m34.646s 4m51.648s 8192 0m33.881s 4m55.342s 16384 0m35.190s 5m00.122s 32768 0m35.060s 4m58.851s 65536 0m33.311s* 4m51.420s It's similarly good. As with the "separate blob LRU" strategy, there's a lot of noise on the log-S run here. But it's certainly not any worse, is possibly a bit better, and the improvement over "separate blob LRU" on the git.git case is dramatic. So it seems like a clear winner, and that's what this patch implements. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2016-08-23delta_base_cache: use list.h for LRUJeff King1-22/+16
We keep an LRU list of entries for when we need to drop something from an over-full cache. The list is implemented as a circular doubly-linked list, which is exactly what list.h provides. We can save a few lines by using the list.h macros and functions. More importantly, this makes the code easier to follow, as the reader sees explicit concepts like "list_add_tail()" instead of pointer manipulation. As a bonus, the list_entry() macro lets us place the lru pointers anywhere inside the delta_base_cache_entry struct (as opposed to just casting the pointer, which requires it at the front of the struct). This will be useful in later patches when we need to place other items at the front of the struct (e.g., our hashmap implementation requires this).

2016-08-23clear_delta_base_cache_entry: use a more descriptive nameJeff King1-2/+7
The delta base cache entries are stored in a fixed-length hash table. So the way to remove an entry is to "clear" the slot in the table, and that is what this function does. However, the name is a leaky abstraction. If we were to change the hash table implementation, it would no longer be about "clearing". We should name it after _what_ it does, not _how_ it does it. I.e., something like "remove" instead of "clear". But that does not tell the whole story, either. The subtle thing about this function is that it removes the entry, but does not free the entry data. So a more descriptive name is "detach"; we give ownership of the data buffer to the caller, and remove any other resources. This patch uses the name detach_delta_base_cache_entry(). We could further model this after functions like strbuf_detach(), which pass back all of the detached information. However, since there are so many bits of information in the struct (the data, the size, the type), and so few callers (only one), it's not worth that awkwardness. The name change and a comment can make the intent clear. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>

There is only one caller of cache_or_unpack_entry() and it always passes 1 for the keep_cache parameter. We can simplify it by dropping the "!keep_cache" case. Another call, which did pass 0, was dropped in abe601b (sha1_file: remove recursion in unpack_entry, 2013-03-27), as unpack_entry() now does more complicated things than a simple unpack when there is a cache miss.

2016-08-23mingw: ensure temporary file handles are not inherited by child processesBen Wijen6-2/+23
When the index is locked and child processes inherit the handle to said lock and the parent process wants to remove the lock before the child process exits, on Windows there is a problem: it won't work because files cannot be deleted if a process holds a handle on them. The symptom: Rename from 'xxx/.git/index.lock' to 'xxx/.git/index' failed. Should I try again? (y/n) Spawning child processes with bInheritHandles==FALSE would not work because no file handles would be inherited, not even the hStdXxx handles in STARTUPINFO (stdin/stdout/stderr). Opening every file with O_NOINHERIT does not work, either, as e.g. git-upload-pack expects inherited file handles. This leaves us with the only way out: creating temp files with the O_NOINHERIT flag. This flag is Windows-specific, however. For our purposes, it is equivalent to O_CLOEXEC (which does not exist on Windows), so let's just open temporary files with the O_CLOEXEC flag and map that flag to O_NOINHERIT on Windows. As Eric Wong pointed out, we need to be careful to handle the case where the Linux headers used to compile Git support O_CLOEXEC but the Linux kernel used to run Git does not: it returns an EINVAL. This fixes the test that we just introduced to demonstrate the problem.

2016-08-18t6026-merge-attr: child processes must not inherit index.lock handlesBen Wijen1-0/+13
On Windows, a file cannot be removed unless all file handles to it have been released. Hence it is particularly important to close handles when spawning children (which would probably not even know that they hold on to those handles). The example chosen for this test is a custom merge driver that indeed has no idea that it blocks the deletion of index.lock. The full use case is a daemon that lives on after the merge, with subsequent invocations handing off to the daemon, thereby avoiding hefty start-up costs. We simulate this behavior by simply sleeping one second. Note that the test only fails on Windows, due to the file locking issue. Since we have no way to say "expect failure with MINGW, success otherwise", we simply skip this test on Windows for now.

2016-08-17clone: recursive and reference option triggers submodule alternatesStefan Beller4-0/+176
When `--recursive` and `--reference` is given, it is reasonable to expect that the submodules are created with references to the submodules of the given alternate for the superproject. An initial attempt to do this was presented to the mailing list, which used flags that are passed around ("--super-reference") that instructed the submodule clone to look for a reference in the submodules of the referenced superproject. This is not well thought out, as any further `submodule update` should also respect the initial setup. When a new submodule is added to the superproject and the alternate of the superproject does not know about that submodule yet, we rather error out informing the user instead of being unclear if we did or did not use a submodules alternate. To solve this problem introduce new options that store the configuration for what the user wanted originally.

Let's merge it up to more modern codebase that has Peff's gpg-interface clean-up topic that appeared after Git 2.9 was tagged. * lt/gpg-show-long-key-in-signature-verification-maint: gpg-interface: prefer "long" key format output when verifying pgp signatures
2016-08-16gpg-interface: prefer "long" key format output when verifying pgp signaturesLinus Torvalds1-2/+2
Yes, gpg2 already uses the long format by default, but most distributions seem to still have "gpg" be the older 1.x version due to compatibility reasons. And older versions of gpg only show the 32-bit short ID, which is quite insecure. This doesn't actually matter for the _verification_ itself: if the verification passes, the pgp signature is good. But if you don't actually have the key yet, and want to fetch it, or you want to check exactly which key was used for verification and want to check it, we should specify the key with more precision. In fact, we should preferentially specify the whole key fingerprint, but gpg doesn't actually support that. Which is really quite sad. Showing the "long" format improves things to at least show 64 bits of the fingerprint. That's a lot better, even if it's not perfect. This change the log format for "git log --show-signature" from commit 2376d31787760af598db23bb3982a57419854e5c merged tag 'v2.9.3' gpg: Signature made Fri 12 Aug 2016 09:17:59 AM PDT using RSA key ID 96AFE6CB gpg: Good signature from "Junio C Hamano <gitster@pobox.com>" gpg: aka "Junio C Hamano <jch@google.com>" gpg: aka "Junio C Hamano <junio@pobox.com>" Merge: 2807cd7b25af e0c1ceafc5be Author: Junio C Hamano <gitster@pobox.com> Date: Fri Aug 12 10:02:18 2016 -0700 to commit 2376d31787760af598db23bb3982a57419854e5c merged tag 'v2.9.3' gpg: Signature made Fri 12 Aug 2016 09:17:59 AM PDT gpg: using RSA key B0B5E88696AFE6CB gpg: Good signature from "Junio C Hamano <gitster@pobox.com>" gpg: aka "Junio C Hamano <jch@google.com>" gpg: aka "Junio C Hamano <junio@pobox.com>" Merge: 2807cd7b25af e0c1ceafc5be Author: Junio C Hamano <gitster@pobox.com> Date: Fri Aug 12 10:02:18 2016 -0700 (note the longer key ID, but also the reflowing of the text) and also changes the format in the merge messages when merging a signed tag. If you already use gpg2 (either because it's installed by default, or because you have set your gpg_program configuration to point to gpg2), that already used the long format, you'll also see a change: it will now have the same formatting as gpg 1.x, and the verification string looks something like gpg: Signature made Sun 24 Jul 2016 12:24:02 PM PDT gpg: using RSA key 79BE3E4300411886 gpg: Good signature from "Linus Torvalds <torvalds@linux-foundation.org>" [ultimate] where it used to be on one line: gpg: Signature made Sun 24 Jul 2016 12:24:02 PM PDT using RSA key ID 79BE3E4300411886 gpg: Good signature from "Linus Torvalds <torvalds@linux-foundation.org>" [ultimate] so there is certainly a chance this could break some automated scripting. But the 32-bit key ID's really are broken. Also note that because of the differences between gpg-1.x and gpg-2.x, hopefully any scripted key ID parsing code (if such code exists) is already flexible enough to not care. This was triggered by the fact that the "evil32" project keys ended up leaking to the public key servers, so now there are 32-bit aliases for just about every open source developer that you can easily get by mistake if you use the 32-bit short ID format.

2016-08-16t/Makefile: ensure that paths are valid on platforms we careJohannes Schindelin1-1/+10
Some pathnames that are okay on ext4 and on HFS+ cannot be checked out on Windows. Tests that want to see operations on such paths on filesystems that support them must do so behind appropriate test prerequisites, and must not include them in the source tree (instead they should create them when they run). Otherwise, the source tree cannot even be checked out. Make sure that double-quotes, asterisk, colon, greater/less-than, question-mark, backslash, tab, vertical-bar, as well as any non-ASCII characters never appear in the pathnames with a new test-lint-* target as part of a `make test`. To that end, we call `git ls-files` (ensuring that the paths are quoted properly), relying on the fact that paths containing non-ASCII characters are quoted within double-quotes. In case that the source code does not actually live in a Git repository (e.g. when extracted from a .zip file), or that the `git` executable cannot be executed, we simply ignore the error for now; In that case, our trusty Continuous Integration will be the last line of defense and catch any problematic file name.

At the moment difftool's "trust exit code" logic always suppresses the exit status of the diff utility we invoke. This is useful because we don't want to exit just because diff returned "1" because the files differ, but it's confusing if the shell returns an error because the selected diff utility is not found. POSIX specifies 127 as the exit status for "command not found", 126 for "command found but is not executable" and values greater than 128 if the command terminated because it received a signal [1] and at least bash and dash follow this specification, while diff utilities generally use "1" for the exit status we want to ignore. Handle any value of 126 or greater as a special value indicating that some form of fatal error occurred.

2016-08-14convert: Correct NNO tests and missing `LF will be replaced by CRLF`Torsten Bögershausen2-43/+60
When a non-reversible CRLF conversion is done in "git add", a warning is printed on stderr (or Git dies, depending on checksafe) The function commit_chk_wrnNNO() in t0027 was written to test this, but did the wrong thing: Instead of looking at the warning from "git add", it looked at the warning from "git commit". This is racy because "git commit" may not have to do CRLF conversion at all if it can use the sha1 value from the index (which depends on whether "add" and "commit" run in a single second). Correct t0027 and replace the commit for each and every file with a commit of all files in one go. The function commit_chk_wrnNNO() should be renamed in a separate commit. Now that t0027 does the right thing, it detects a bug in covert.c: This sequence should generate the warning `LF will be replaced by CRLF`, but does not: $ git init $ git config core.autocrlf false $ printf "Line\r\n" >file $ git add file $ git commit -m "commit with CRLF" $ git config core.autocrlf true $ printf "Line\n" >file $ git add file "git add" calls crlf_to_git() in convert.c, which calls check_safe_crlf(). When has_cr_in_index(path) is true, crlf_to_git() returns too early and check_safe_crlf() is not called at all. Factor out the code which determines if "git checkout" converts LF->CRLF into will_convert_lf_to_crlf(). Update the logic around check_safe_crlf() and "simulate" the possible LF->CRLF conversion at "git checkout" with help of will_convert_lf_to_crlf().

2016-08-13merge-recursive: fix verbose output for multiple base treesRené Scharfe2-4/+19
One of the indirect callers of make_virtual_commit() passes the result of oid_to_hex() as the name, i.e. a pointer to a static buffer. Since the function uses that string pointer directly in building a struct merge_remote_desc, multiple entries can end up sharing the same name inadvertently. Fix that by calling set_merge_remote_desc(), which creates a copy of the string, instead of building the struct by hand.

2016-08-12submodule--helper update-clone: allow multiple referencesStefan Beller2-6/+10
Allow the user to pass in multiple references to update_clone. Currently this is only internal API, but once the shell script is replaced by a C version, this is needed. This fixes an API bug between the shell script and the helper. Currently the helper accepts "--reference" "--reference=foo" as a OPT_STRING whose value happens to be "--reference=foo", and then uses if (suc->reference) argv_array_push(&child->args, suc->reference) where suc->reference _is_ "--reference=foo" when invoking the underlying "git clone", it cancels out. With this change we omit one of the "--reference" arguments when passing references from the shell script to the helper.

2016-08-11rebase: avoid computing unnecessary patch IDsKevin Willford5-8/+85
The `rebase` family of Git commands avoid applying patches that were already integrated upstream. They do that by using the revision walking option that computes the patch IDs of the two sides of the rebase (local-only patches vs upstream-only ones) and skipping those local patches whose patch ID matches one of the upstream ones. In many cases, this causes unnecessary churn, as already the set of paths touched by a given commit would suffice to determine that an upstream patch has no local equivalent. This hurts performance in particular when there are a lot of upstream patches, and/or large ones. Therefore, let's introduce the concept of a "diff-header-only" patch ID, compare those first, and only evaluate the "full" patch ID lazily. Please note that in contrast to the "full" patch IDs, those "diff-header-only" patch IDs are prone to collide with one another, as adjacent commits frequently touch the very same files. Hence we now have to be careful to allow multiple hash entries with the same hash. We accomplish that by using the hashmap_add() function that does not even test for hash collisions. This also allows us to evaluate the full patch ID lazily, i.e. only when we found commits with matching diff-header-only patch IDs. We add a performance test that demonstrates ~1-6% improvement. In practice this will depend on various factors such as how many upstream changes and how big those changes are along with whether file system caches are cold or warm. As Git's test suite has no way of catching performance regressions, we also add a regression test that verifies that the full patch ID computation is skipped when the diff-header-only computation suffices.
