2016-01-26Merge branch 'js/close-packs-before-gc'Junio C Hamano1-0/+2
Many codepaths that run "gc --auto" before exiting kept packfiles mapped and left the file descriptors to them open, which was not friendly to systems that cannot remove files that are open. They now close the packs before doing so. * js/close-packs-before-gc: receive-pack: release pack files before garbage-collecting merge: release pack files before garbage-collecting am: release pack files before garbage-collecting fetch: release pack files before garbage-collecting
2016-01-20Merge branch 'js/fopen-harder'Junio C Hamano1-1/+1
Some codepaths used fopen(3) when opening a fixed path in $GIT_DIR (e.g. COMMIT_EDITMSG) that is meant to be left after the command is done. This however did not work well if the repository is set to be shared with core.sharedRepository and the umask of the previous user is tighter. They have been made to work better by calling unlink(2) and retrying after fopen(3) fails with EPERM. * js/fopen-harder: Handle more file writes correctly in shared repos commit: allow editing the commit message even in shared repos

2016-01-11Handle more file writes correctly in shared reposJohannes Schindelin1-1/+1
In shared repositories, we have to be careful when writing files whose permissions do not allow users other than the owner to write them. In particular, we force the marks file of fast-export and the FETCH_HEAD when fetching to be rewritten from scratch. This commit does not touch other calls to fopen() that want to write files: - commands that write to working tree files (core.sharedRepository does not affect permission bits of working tree files), e.g. .rej file created by "apply --reject", result of applying a previous conflict resolution by "rerere", "git merge-file". - git am, when splitting mails (git-am correctly cleans up its directory after finishing, so there is no need to share those files between users) - git submodule clone, when writing the .git file, because the file will not be overwritten - git_terminal_prompt() in compat/terminal.c, because it is not writing to a file at all - git diff --output, because the output file is clearly not intended to be shared between the users of the current repository - git fast-import, when writing a crash report, because the reports' file names are unique due to an embedded process ID - mailinfo() in mailinfo.c, because the output is clearly not intended to be shared between the users of the current repository - check_or_regenerate_marks() in remote-testsvn.c, because this is only used for Git's internal testing - git fsck, when writing lost&found blobs (this should probably be changed, but left as a low-hanging fruit for future contributors). Note that this patch does not touch callers of write_file() and write_file_gently(), which would benefit from the same scrutiny as to usage in shared repositories. Most notable users are branch, daemon, submodule & worktree, and a worrisome call in transport.c when updating one ref (which ignores the shared flag).

2015-10-05transport: use strbufs for status table "quickref" stringsJeff King1-10/+12
We generate range strings like "1234abcd...5678efab" for use in the the fetch and push status tables. We use fixed-size buffers along with strcat to do so. These aren't buggy, as our manual size computation is correct, but there's nothing checking that this is so. Let's switch them to strbufs instead, which are obviously correct, and make it easier to audit the code base for problematic calls to strcat().

2015-09-25fetch: replace static buffer with xstrfmtJeff King1-5/+2
We parse the INFINITE_DEPTH constant into a static, fixed-size buffer using sprintf. This buffer is sufficiently large for the current constant, but it's a suspicious pattern, as the constant is defined far away, and it's not immediately obvious that 12 bytes are large enough to hold it. We can just use xstrfmt here, which gets rid of any question of the buffer size. It also removes any concerns with object lifetime, which means we do not have to wonder why this buffer deep within a conditional is marked "static" (we never free our newly allocated result, of course, but that's OK; it's global that lasts the lifetime of the whole program anyway).

2015-08-10memoize common git-path "constant" filesJeff King1-2/+2
One of the most common uses of git_path() is to pass a constant, like git_path("MERGE_MSG"). This has two drawbacks: 1. The return value is a static buffer, and the lifetime is dependent on other calls to git_path, etc. 2. There's no compile-time checking of the pathname. This is OK for a one-off (after all, we have to spell it correctly at least once), but many of these constant strings appear throughout the code. This patch introduces a series of functions to "memoize" these strings, which are essentially globals for the lifetime of the program. We compute the value once, take ownership of the buffer, and return the cached value for subsequent calls. cache.h provides a helper macro for defining these functions as one-liners, and defines a few common ones for global use. Using a macro is a little bit gross, but it does nicely document the purpose of the functions. If we need to touch them all later (e.g., because we learned how to change the git_dir variable at runtime, and need to invalidate all of the stored values), it will be much easier to have the complete list. Note that the shared-global functions have separate, manual declarations. We could do something clever with the macros (e.g., expand it to a declaration in some places, and a declaration _and_ a definition in path.c). But there aren't that many, and it's probably better to stay away from too-magical macros. Likewise, if we abandon the C preprocessor in favor of generating these with a script, we could get much fancier. E.g., normalizing "FOO/BAR-BAZ" into "git_path_foo_bar_baz". But the small amount of saved typing is probably not worth the resulting confusion to readers who want to grep for the function's definition.

2015-06-22prune_refs(): use delete_refs()Michael Haggerty1-8/+17
The old version just looped over the references to delete, calling delete_ref() on each one. But that has quadratic behavior, because each call to delete_ref() might have to rewrite the packed-refs file. This can be very expensive in a repository with a large number of references. In some (admittedly extreme) repositories, we've seen cases where the ref-pruning part of fetch takes multiple tens of minutes. Instead call delete_refs(), which (aside from being less code) has the optimization that it only rewrites the packed-refs file a single time.

2015-05-25each_ref_fn: change to take an object_id parameterMichael Haggerty1-2/+6
Change typedef each_ref_fn to take a "const struct object_id *oid" parameter instead of "const unsigned char *sha1". To aid this transition, implement an adapter that can be used to wrap old-style functions matching the old typedef, which is now called "each_ref_sha1_fn"), and make such functions callable via the new interface. This requires the old function and its cb_data to be wrapped in a "struct each_ref_fn_sha1_adapter", and that object to be used as the cb_data for an adapter function, each_ref_fn_adapter(). This is an enormous diff, but most of it consists of simple, mechanical changes to the sites that call any of the "for_each_ref" family of functions. Subsequent to this change, the call sites can be rewritten one by one to use the new interface.

2014-12-01path.c: make get_pathname() call sites return const char *Nguyễn Thái Ngọc Duy1-2/+3
Before the previous commit, get_pathname returns an array of PATH_MAX length. Even if git_path() and similar functions does not use the whole array, git_path() caller can, in theory. After the commit, get_pathname() may return a buffer that has just enough room for the returned string and git_path() caller should never write beyond that. Make git_path(), mkpath() and git_path_submodule() return a const buffer to make sure callers do not write in it at all.

Corner-case bugfixes for "git fetch" around reflog handling. * jk/fetch-reflog-df-conflict: ignore stale directories when checking reflog existence fetch: load all default config at startup
2014-11-04fetch: load all default config at startupJeff King1-1/+1
When we start the git-fetch program, we call git_config to load all config, but our callback only processes the fetch.prune option; we do not chain to git_default_config at all. This means that we may not load some core configuration which will have an effect. For instance, we do not load core.logAllRefUpdates, which impacts whether or not we create reflogs in a bare repository. Note that I said "may" above. It gets even more exciting. If we have to transfer actual objects as part of the fetch, then we call fetch_pack as part of the same process. That function loads its own config, which does chain to git_default_config, impacting global variables which are used by the rest of fetch. But if the fetch is a pure ref update (e.g., a new ref which is a copy of an old one), we skip fetch_pack entirely. So we get inconsistent results depending on whether or not we have actual objects to transfer or not! Let's just load the core config at the start of fetch, so we know we have it (we may also load it again as part of fetch_pack, but that's OK; it's designed to be idempotent). Our tests check both cases (with and without a pack). We also check similar behavior for push for good measure, but it already works as expected.

2013-10-30fetch, remote: properly convey --no-prune options to subprocessesMichael Haggerty1-2/+2
If --no-prune is passed to one of the following commands: git fetch --all git fetch --multiple git fetch --recurse-submodules git remote update then it must also be passed to the "fetch" subprocesses that those commands use to do their work. Otherwise there might be a fetch.prune or remote.<name>.prune configuration setting that causes pruning to occur, contrary to the user's express wish.

2013-10-30fetch --prune: prune only based on explicit refspecsMichael Haggerty1-30/+9
The old behavior of "fetch --prune" was to prune whatever was being fetched. In particular, "fetch --prune --tags" caused tags not only to be fetched, but also to be pruned. This is inappropriate because there is only one tags namespace that is shared among the local repository and all remotes. Therefore, if the user defines a local tag and then runs "git fetch --prune --tags", then the local tag is deleted. Moreover, "--prune" and "--tags" can also be configured via fetch.prune / remote.<name>.prune and remote.<name>.tagopt, making it even less obvious that an invocation of "git fetch" could result in tag lossage. Since the command "git remote update" invokes "git fetch", it had the same problem. The command "git remote prune", on the other hand, disregarded the setting of remote.<name>.tagopt, and so its behavior was inconsistent with that of the other commands. So the old behavior made it too easy to lose tags. To fix this problem, change "fetch --prune" to prune references based only on refspecs specified explicitly by the user, either on the command line or via remote.<name>.fetch. Thus, tags are no longer made subject to pruning by the --tags option or the remote.<name>.tagopt setting. However, tags *are* still subject to pruning if they are fetched as part of a refspec, and that is good. For example: * On the command line, git fetch --prune 'refs/tags/*:refs/tags/*' causes tags, and only tags, to be fetched and pruned, and is therefore a simple way for the user to get the equivalent of the old behavior of "--prune --tag". * For a remote that was configured with the "--mirror" option, the configuration is set to include [remote "name"] fetch = +refs/*:refs/* , which causes tags to be subject to pruning along with all other references. This is the behavior that will typically be desired for a mirror. Signed-off-by: Michael Haggerty <mhagger@alum.mit.edu> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2013-10-30fetch --tags: fetch tags *in addition to* other stuffMichael Haggerty1-24/+35
Previously, fetch's "--tags" option was considered equivalent to specifying the refspec "refs/tags/*:refs/tags/*" on the command line; in particular, it caused the remote.<name>.refspec configuration to be ignored. But it is not very useful to fetch tags without also fetching other references, whereas it *is* quite useful to be able to fetch tags *in addition to* other references. So change the semantics of this option to do the latter. If a user wants to fetch *only* tags, then it is still possible to specifying an explicit refspec: git fetch <remote> 'refs/tags/*:refs/tags/*' Please note that the documentation prior to 1.8.0.3 was ambiguous about this aspect of "fetch --tags" behavior. Commit f0cb2f137c 2012-12-14 fetch --tags: clarify documentation made the documentation match the old behavior. This commit changes the documentation to match the new behavior.

2013-10-30fetch: only opportunistically update references based on command lineMichael Haggerty1-12/+32
The old code processed (tags == TAGS_SET) before adding the entries used to opportunistically update references mentioned on the command line. The result was that all tags were also considered candidates for opportunistic updating. This is harmless for two reasons: (a) because it would only add entries if there is a configured refspec that covers tags *and* both --tags and another refspec appear on the command-line; (b) because any extra entries would be deleted later by the call to ref_remove_duplicates() anyway. But, to avoid extra work and extra memory usage, and to make the implementation better match the intention, change the algorithm slightly: compute the opportunistic refspecs based only on the command-line arguments, storing the results into a separate temporary list. Then add the tags (which have to come earlier in the list so that they are not de-duped in favor of an opportunistic entry). Then concatenate the temporary list onto the main list. This change will also make later changes easier. Signed-off-by: Michael Haggerty <mhagger@alum.mit.edu> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2013-08-07fetch: work around "transport-take-over" hackJunio C Hamano1-0/+13
A Git-aware "connect" transport allows the "transport_take_over" to redirect generic transport requests like fetch(), push_refs() and get_refs_list() to the native Git transport handling methods. The take-over process replaces transport->data with a fake data that these method implementations understand. While this hack works OK for a single request, it breaks when the transport needs to make more than one requests. transport->data that used to hold necessary information for the specific helper to work correctly is destroyed during the take-over process. One codepath that this matters is "git fetch" in auto-follow mode; when it does not get all the tags that ought to point at the history it got (which can be determined by looking at the peeled tags in the initial advertisement) from the primary transfer, it internally makes a second request to complete the fetch. Because "take-over" hack has already destroyed the data necessary to talk to the transport helper by the time this happens, the second request cannot make a request to the helper to make another connection to fetch these additional tags. Mark such a transport as "cannot_reuse", and use a separate transport to perform the backfill fetch in order to work around this breakage. Note that this problem does not manifest itself when running t5802, because our upload-pack gives you all the necessary auto-followed tags during the primary transfer. You would need to step through "git fetch" in a debugger, stop immediately after the primary transfer finishes and writes these auto-followed tags, remove the tag references and repack/prune the repository to convince the "find-non-local-tags" procedure that the primary transfer failed to give us all the necessary tags, and then let it continue, in order to trigger the bug in the secondary transfer this patch fixes.

Without "git fetch --prune", remote-tracking branches for a branch the other side already has removed will stay forever. Some people want to always run "git fetch --prune". To accommodate users who want to either prune always or when fetching from a particular remote, add two new configuration variables "fetch.prune" and "remote.<name>.prune": - "fetch.prune" allows to enable prune for all fetch operations. - "remote.<name>.prune" allows to change the behaviour per remote. The latter will naturally override the former, and the --[no-]prune option from the command line will override the configured default. Since --prune is a potentially destructive operation (Git doesn't keep reflogs for deleted references yet), we don't want to prune without users consent, so this configuration will not be on by default.

2013-05-12fetch: opportunistically update tracking refsJeff King1-0/+16
When we run a regular "git fetch" without arguments, we update the tracking refs according to the configured refspec. However, when we run "git fetch origin master" (or "git pull origin master"), we do not look at the configured refspecs at all, and just update FETCH_HEAD. We miss an opportunity to update "refs/remotes/origin/master" (or whatever the user has configured). Some users find this confusing, because they would want to do further comparisons against the old state of the remote master, like: $ git pull origin master $ git log HEAD...origin/master In the currnet code, they are comparing against whatever commit happened to be in origin/master from the last time they did a complete "git fetch". This patch will update a ref from the RHS of a configured refspec whenever we happen to be fetching its LHS. That makes the case above work. The downside is that any users who really care about whether and when their tracking branches are updated may be surprised.

2013-05-12refactor "ref->merge" flagJeff King1-22/+35
Each "struct ref" has a boolean flag that is set by the fetch code to determine whether the ref should be marked as "not-for-merge" or not when we write it out to FETCH_HEAD. It would be useful to turn this boolean into a tri-state, with the third state meaning "do not bother writing it out to FETCH_HEAD at all". That would let us add extra refs to the set of refs to be stored (e.g., to store copies of things we fetched) without impacting FETCH_HEAD. This patch turns it into an enum that covers the tri-state case, and hopefully makes the code more explicit and easier to read.

2013-01-26fetch: run gc --auto after fetchingJeff King1-0/+5
We generally try to run "gc --auto" after any commands that might introduce a large number of new objects. An obvious place to do so is after running "fetch", which may introduce new loose objects or packs (depending on the size of the fetch). While an active developer repository will probably eventually trigger a "gc --auto" on another action (e.g., git-rebase), there are two good reasons why it is nicer to do it at fetch time: 1. Read-only repositories which track an upstream (e.g., a continuous integration server which fetches and builds, but never makes new commits) will accrue loose objects and small packs, but never coalesce them into a more efficient larger pack. 2. Fetching is often already perceived to be slow to the user, since they have to wait on the network. It's much more pleasant to include a potentially slow auto-gc as part of the already-long network fetch than in the middle of productive work with git-rebase or similar.

The user can do --depth=2147483647 (*) for restoring complete repo now. But it's hard to remember. Any other numbers larger than the longest commit chain in the repository would also do, but some guessing may be involved. Make easy-to-remember --unshallow an alias for --depth=2147483647. Make upload-pack recognize this special number as infinite depth. The effect is essentially the same as before, except that upload-pack is more efficient because it does not have to traverse to the bottom anymore. The chance of a user actually wanting exactly 2147483647 commits depth, not infinite, on a repository with a history that long, is probably too small to consider. The client can learn to add or subtract one commit to avoid the special treatment when that actually happens. (*) This is the largest positive number a 32-bit signed integer can contain. JGit and older C Git store depth as "int" so both are OK with this number. Dulwich does not support shallow clone.

2012-04-14submodules: recursive fetch also checks new tags for submodule commitsJens Lehmann1-3/+3
Since 88a21979c (fetch/pull: recurse into submodules when necessary) all fetched commits are examined if they contain submodule changes (unless configuration or command line options inhibit that). If a newly recorded submodule commit is not present in the submodule, a fetch is run inside it to download that commit. Checking new refs was done in an else branch where it wasn't executed for tags. This normally isn't a problem because tags are only fetched with the branches they live on, then checking the new commits in the fetched branches for submodule commits will also process all tags. But when a specific tag is fetched (or the refspec contains refs/tags/) commits only reachable by tags won't be searched for submodule commits, which is a bug. Fix that by moving the code outside the if/else construct to handle new tags just like any other ref. The performance impact of adding tags that most of the time lie on a branch which is checked anyway for new submodule commit should be minimal, as since 6859de4 (fetch: avoid quadratic loop checking for updated submodules) all ref-tips are collected first and then fed to a single rev-list.

2012-01-03write first for-merge ref to FETCH_HEAD firstJoey Hess1-74/+86
The FETCH_HEAD refname is supposed to refer to the ref that was fetched and should be merged. However all fetched refs are written to .git/FETCH_HEAD in an arbitrary order, and resolve_ref_unsafe simply takes the first ref as the FETCH_HEAD, which is often the wrong one, when other branches were also fetched. The solution is to write the for-merge ref(s) to FETCH_HEAD first. Then, unless --append is used, the FETCH_HEAD refname behaves as intended. If the user uses --append, they presumably are doing so in order to preserve the old FETCH_HEAD. While we are at it, update an old example in the read-tree documentation that implied that each entry in FETCH_HEAD only has the object name, which is not true for quite a while.

If the user gave us refspecs on the command line, we should use those when deciding whether to prune a ref instead of relying on the refspecs in the config. Previously, running git fetch --prune origin refs/heads/master:refs/remotes/origin/master would delete every other ref under the origin namespace because we were using the refspec to filter the available refs but using the configured refspec to figure out if a ref had been deleted on the remote. This is clearly the wrong thing to do. Change prune_refs and get_stale_heads to simply accept a list of references and a list of refspecs.

2011-03-09fetch/pull: recurse into submodules when necessaryJens Lehmann1-9/+17
To be able to access all commits of populated submodules referenced by the superproject it is sufficient to only then let "git fetch" recurse into a submodule when the new commits fetched in the superproject record new commits for it. Having these commits present is extremely useful when using the "--submodule" option to "git diff" (which is what "git gui" and "gitk" do since 1.6.6), as all submodule commits needed for creating a descriptive output can be accessed. Also merging submodule commits (added in 1.7.3) depends on the submodule commits in question being present to work. Last but not least this enables disconnected operation when using submodules, as all commits necessary for a successful "git submodule update -N" will have been fetched automatically. So we choose this mode as the default for fetch and pull. Before a new or changed ref from upstream is updated in update_local_ref() "git rev-list <new-sha1> --not --branches --remotes" is used to determine all newly fetched commits. These are then walked and diffed against their parent(s) to see if a submodule has been changed. If that is the case, its path is stored to be fetched after the superproject fetch is completed. Using the "--recurse-submodules" or the "--no-recurse-submodules" option disables the examination of the fetched refs because the result will be ignored anyway. There is currently no infrastructure for storing deleted and new submodules in the .git directory of the superproject. That's why fetch and pull for now only fetch submodules that are already checked out and are not renamed. In t7403 the "--no-recurse-submodules" argument had to be added to "git pull" to avoid failure because of the moved upstream submodule repo.

2011-03-08add packet tracing debug codeJeff King1-0/+2
This shows a trace of all packets coming in or out of a given program. This can help with debugging object negotiation or other protocol issues. To keep the code changes simple, we operate at the lowest level, meaning we don't necessarily understand what's in the packets. The one exception is a packet starting with "PACK", which causes us to skip that packet and turn off tracing (since the gigantic pack data will not be interesting to read, at least not in the trace format). We show both written and read packets. In the local case, this may mean you will see packets twice (written by the sender and read by the receiver). However, for cases where the other end is remote, this allows you to see the full conversation. Packet tracing can be enabled with GIT_TRACE_PACKET=<foo>, where <foo> takes the same arguments as GIT_TRACE.

2010-11-12fetch/pull: Add the --recurse-submodules optionJens Lehmann1-14/+39
Until now you had to call "git submodule update" (without -N|--no-fetch option) or something like "git submodule foreach git fetch" to fetch new commits in populated submodules from their remote. This could lead to "(commits not present)" messages in the output of "git diff --submodule" (which is used by "git gui" and "gitk") after fetching or pulling new commits in the superproject and is an obstacle for implementing recursive checkout of submodules. Also "git submodule update" cannot fetch changes when disconnected, so it was very easy to forget to fetch the submodule changes before disconnecting only to discover later that they are needed. This patch adds the "--recurse-submodules" option to recursively fetch each populated submodule from the url configured in the .git/config of the submodule at the end of each "git fetch" or during "git pull" in the superproject. The submodule paths are taken from the index. The hidden option "--submodule-prefix" is added to "git fetch" to be able to print out the full paths of nested submodules.

2010-08-25builtin/fetch.c: ignore merge config when not fetching from branch's remoteBrandon Casey1-1/+3
When 'git fetch' is supplied a single argument, it tries to match it against a configured remote and then fetch the refs specified by the named remote's fetchspec. Additionally, or alternatively, if the current branch has a merge ref configured, and if the name of the remote supplied to fetch matches the one in the branch's configuration, then git also adds the merge ref to the list of refs to update. If the argument to fetch does not specify a named remote, or if the name supplied does not match the remote configured for the current branch, then the current branch's merge configuration should not be considered. git currently mishandles the case when the argument to fetch specifies a GIT URL(i.e. not a named remote) and the current branch has a configured merge ref. In this case, fetch should ignore the branch's merge ref and attempt to fetch from the remote repository's HEAD branch. But, since fetch only checks _whether_ the current branch has a merge ref configured, and does _not_ check whether the branch's configured remote matches the command line argument (until later), it will mistakenly enter the wrong branch of an 'if' statement and will not fall back to fetch the HEAD branch. The fetch ends up doing nothing and returns with a successful zero status. Fix this by comparing the remote repository's name to the branch's remote name, in addition to whether it has a configured merge ref, sooner, so that fetch can correctly decide whether the branch's configuration is interesting or not, and fall back to fetching from the remote's HEAD branch when appropriate. This fixes the test in t5510. Signed-off-by: Brandon Casey <casey@nrlssc.navy.mil> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2010-07-05Convert the users of for_each_string_list to for_each_string_list_item macroAlex Riesen1-29/+13
The rule for selecting the candidates for conversion is: if the callback function returns only 0 (the condition for for_each_string_list to exit early), than it can be safely converted to the macro. A notable exception are the callers in builtin/remote.c. If converted, the readability in the file will suffer greately. Besides, the code is not very performance critical (at the moment, at least): it does output formatting of the list of remotes.

2010-05-31Rewrite dynamic structure initializations to runtime assignmentGary V. Vaughan1-2/+4
Unfortunately, there are still plenty of production systems with vendor compilers that choke unless all compound declarations can be determined statically at compile time, for example hpux10.20 (I can provide a comprehensive list of our supported platforms that exhibit this problem if necessary). This patch simply breaks apart any compound declarations with dynamic initialisation expressions, and moves the initialisation until after the last declaration in the same block, in all the places necessary to have the offending compilers accept the code.

This shrinks the top-level directory a bit, and makes it much more pleasant to use auto-completion on the thing. Instead of [torvalds@nehalem git]$ em buil<tab> Display all 180 possibilities? (y or n) [torvalds@nehalem git]$ em builtin-sh builtin-shortlog.c builtin-show-branch.c builtin-show-ref.c builtin-shortlog.o builtin-show-branch.o builtin-show-ref.o [torvalds@nehalem git]$ em builtin-shor<tab> builtin-shortlog.c builtin-shortlog.o [torvalds@nehalem git]$ em builtin-shortlog.c you get [torvalds@nehalem git]$ em buil<tab> [type] builtin/ builtin.h [torvalds@nehalem git]$ em builtin [auto-completes to] [torvalds@nehalem git]$ em builtin/sh<tab> [type] shortlog.c shortlog.o show-branch.c show-branch.o show-ref.c show-ref.o [torvalds@nehalem git]$ em builtin/sho [auto-completes to] [torvalds@nehalem git]$ em builtin/shor<tab> [type] shortlog.c shortlog.o [torvalds@nehalem git]$ em builtin/shortlog.c which doesn't seem all that different, but not having that annoying break in "Display all 180 possibilities?" is quite a relief. NOTE! If you do this in a clean tree (no object files etc), or using an editor that has auto-completion rules that ignores '*.o' files, you won't see that annoying 'Display all 180 possibilities?' message - it will just show the choices instead. I think bash has some cut-off around 100 choices or something. So the reason I see this is that I'm using an odd editory, and thus don't have the rules to cut down on auto-completion. But you can simulate that by using 'ls' instead, or something similar. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> Signed-off-by: Junio C Hamano <gitster@pobox.com>
