2015-10-18tag.c: use the correct algorithm for the '--contains' optionLibravatar Karthik Nayak1-0/+1
In b7cc53e9 (tag.c: use 'ref-filter' APIs, 2015-09-11) we port tag.c to use the ref-filter APIs for filtering and printing refs. In ref-filter we have two implementations for filtering refs when the '--contains' option is used. Although they do the same thing, one is optimized for filtering branches and the other for tags (borrowed from branch.c and tag.c respectively) and the 'filter->with_commit_tag_algo' bit decides which algorithm must be used. We should unify these. When we ported tag.c to use ref-filter APIs we missed out on setting the 'filter->with_commit_tag_algo' bit. As reported by Jerry Snitselaar, this causes "git tag --contains" to work way slower than expected, fix this by setting 'filter->with_commit_tag_algo' in tag.c before calling 'filter_refs()'.

2015-10-16usage: do not insist that standard input must come from a fileLibravatar Junio C Hamano11-12/+12
The synopsys text and the usage string of subcommands that read list of things from the standard input are often shown like this: git gostak [--distim] < <list-of-doshes> This is problematic in a number of ways: * The way to use these commands is more often to feed them the output from another command, not feed them from a file. * Manual pages outside Git, commands that operate on the data read from the standard input, e.g "sort", "grep", "sed", etc., are not described with such a "< redirection-from-file" in their synopsys text. Our doing so introduces inconsistency. * We do not insist on where the output should go, by saying git gostak [--distim] < <list-of-doshes> > <output> * As it is our convention to enclose placeholders inside <braket>, the redirection operator followed by a placeholder filename becomes very hard to read, both in the documentation and in the help text. Let's clean them all up, after making sure that the documentation clearly describes the modes that take information from the standard input and what kind of things are expected on the input.

2015-10-09am -3: do not let failed merge from completing the error codepathLibravatar Junio C Hamano1-16/+33
When "am" was rewritten in C, the codepath for falling back to three-way merge was mistakenly made to make an internal call to merge-recursive, disabling the error reporting code for certain types of errors merge-recursive detects and reports by calling die(). This is a quick-fix for correctness. The ideal endgame would be to replace run_command() in run_fallback_merge_recursive() with a direct call after making sure that internal call to merge-recursive does not die().

2015-10-07clone --dissociate: avoid locking pack filesLibravatar Johannes Schindelin1-1/+3
When `git clone` is asked to dissociate the repository from the reference repository whose objects were used, it is quite possible that the pack files need to be repacked. In that case, the pack files need to be deleted that were originally hard-links to the reference repository's pack files. On platforms where a file cannot be deleted if another process still holds a handle on it, we therefore need to take pains to release all pack files and indexes before dissociating. This fixes https://github.com/git-for-windows/git/issues/446 The test case to demonstrate the breakage technically does not need to be run on Linux or MacOSX. It won't hurt, either, though.

2015-10-05use strbuf_complete to conditionally append slashLibravatar Jeff King2-6/+3
When working with paths in strbufs, we frequently want to ensure that a directory contains a trailing slash before appending to it. We can shorten this code (and make the intent more obvious) by calling strbuf_complete. Most of these cases are trivially identical conversions, but there are two things to note: - in a few cases we did not check that the strbuf is non-empty (which would lead to an out-of-bounds memory access). These were generally not triggerable in practice, either from earlier assertions, or typically because we would have just fed the strbuf to opendir(), which would choke on an empty path. - in a few cases we indexed the buffer with "original_len" or similar, rather than the current sb->len, and it is not immediately obvious from the diff that they are the same. In all of these cases, I manually verified that the strbuf does not change between the assignment and the strbuf_complete call. This does not convert cases which look like: if (sb->len && !is_dir_sep(sb->buf[sb->len - 1])) strbuf_addch(sb, '/'); as those are obviously semantically different. Some of these cases arguably should be doing that, but that is out of scope for this change, which aims purely for cleanup with no behavior change (and at least it will make such sites easier to find and examine in the future, as we can grep for strbuf_complete).

Since 27e1e22 (prune: factor out loose-object directory traversal, 2014-10-15), we now have a generic callback system for iterating over the loose object directories. This is used by prune, count-objects, etc. We did not convert git-fsck at the time because it implemented an inode-sorting scheme that was not part of the generic code. Now that the inode-sorting code is gone, we can reuse the generic code. The result is shorter, hopefully more readable, and drops some unchecked sprintf calls.

2015-10-05fsck: drop inode-sorting codeLibravatar Jeff King1-68/+2
Fsck tries to access loose objects in order of inode number, with the hope that this would make cold cache access faster on a spinning disk. This dates back to 7e8c174 (fsck-cache: sort entries by inode number, 2005-05-02), which predates the invention of packfiles. These days, there's not much point in trying to optimize cold cache for a large number of loose objects. You are much better off to simply pack the objects, which will reduce the disk footprint _and_ provide better locality of data access. So while you can certainly construct pathological cases where this code might help, it is not worth the trouble anymore.

strncpy is known to be a confusing function because of its termination semantics. These calls are all correct, but it takes some examination to see why. In particular, every one of them expects to copy up to the length limit, and then makes some arrangement for terminating the result. We can just use memcpy, along with noting explicitly how the result is terminated (if it is not already obvious). That should make it more clear to a reader that we are doing the right thing.

2015-10-05help: clean up kfmclient mungingLibravatar Jeff King1-11/+4
When we are going to launch "/path/to/konqueror", we instead rewrite this into "/path/to/kfmclient" by duplicating the original string and writing over the ending bits. This can be done more obviously with strip_suffix and xstrfmt. Note that we also fix a subtle bug with the "filename" parameter, which is passed as argv[0] to the child. If the user has configured a program name with no directory component, we always pass the string "kfmclient", even if your program is called something else. But if you give a full path, we give the basename of that path. But more bizarrely, if we rewrite "konqueror" to "kfmclient", we still pass "konqueror". The history of this function doesn't reveal anything interesting, so it looks like just an oversight from combining the suffix-munging with the basename-finding. Let's just call basename on the munged path, which produces consistent results (if you gave a program, whether a full path or not, we pass its basename). Probably this doesn't matter at all in practice, but it makes the code slightly less confusing to read. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>

To generate "--keep=receive-pack $pid on $host", we write progressively into a single buffer, which requires keeping track of how much we've written so far. But since the result is destined to go into our argv array, we can simply use argv_array_pushf. Unfortunately we still have to have a fixed-size buffer for the gethostname() call, but at least it now doesn't involve any extra size computation. And as a bonus, we drop an sprintf and a strcpy call. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2015-10-05avoid sprintf and strcpy with flex arraysLibravatar Jeff King1-2/+3
When we are allocating a struct with a FLEX_ARRAY member, we generally compute the size of the array and then sprintf or strcpy into it. Normally we could improve a dynamic allocation like this by using xstrfmt, but it doesn't work here; we have to account for the size of the rest of the struct. But we can improve things a bit by storing the length that we use for the allocation, and then feeding it to xsnprintf or memcpy, which makes it more obvious that we are not writing more than the allocated number of bytes. It would be nice if we had some kind of helper for allocating generic flex arrays, but it doesn't work that well: - the call signature is a little bit unwieldy: d = flex_struct(sizeof(*d), offsetof(d, path), fmt, ...); You need offsetof here instead of just writing to the end of the base size, because we don't know how the struct is packed (partially this is because FLEX_ARRAY might not be zero, though we can account for that; but the size of the struct may actually be rounded up for alignment, and we can't know that). - some sites do clever things, like over-allocating because they know they will write larger things into the buffer later (e.g., struct packed_git here). So we're better off to just write out each allocation (or add type-specific helpers, though many of these are one-off allocations anyway).

Before sha1_to_hex_r() existed, a simple way to get hex sha1 into a buffer was with: strcpy(buf, sha1_to_hex(sha1)); This isn't wrong (assuming the buf is 41 characters), but it makes auditing the code base for bad strcpy() calls harder, as these become false positives. Let's convert them to sha1_to_hex_r(), and likewise for some calls to find_unique_abbrev(). While we're here, we'll double-check that all of the buffers are correctly sized, and use the more obvious GIT_SHA1_HEXSZ constant.
