2019-01-24cache.h: flip NO_THE_INDEX_COMPATIBILITY_MACROS switchNguyễn Thái Ngọc Duy
By default, index compat macros are off from now on, because they could hide the_index dependency. Only those in builtin can use it. Signed-off-by: Nguyễn Thái Ngọc Duy <pclouds@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2018-08-13attr: remove index from git_attr_set_direction()Nguyễn Thái Ngọc Duy
Since attr checking API now take the index, there's no need to set an index in advance with this call. Most call sites are straightforward because they either pass the_index or NULL (which defaults back to the_index previously). There's only one suspicious call site in unpack-trees.c where it sets a different index. This code in unpack-trees is about to check out entries from the new/temporary index after merging is done in it. The attributes will be used by entry.c code to do crlf conversion if needed. entry.c now respects struct checkout's istate field, and this field is correctly set in unpack-trees.c, there should be no regression from this change.

2018-08-13attr: remove an implicit dependency on the_indexNguyễn Thái Ngọc Duy
Make the attr API take an index_state instead of assuming the_index in attr code. All call sites are converted blindly to keep the patch simple and retain current behavior. Individual call sites may receive further updates to use the right index instead of the_index. There is one ugly temporary workaround added in attr.c that needs some more explanation. Commit c24f3abace (apply: file commited with CRLF should roundtrip diff and apply - 2017-08-19) forces one convert_to_git() call to NOT read the index at all. But what do you know, we read it anyway by falling back to the_index. When "istate" from convert_to_git is now propagated down to read_attr_from_array() we will hit segfault somewhere inside read_blob_data_from_index. The right way of dealing with this is to kill "use_index" variable and only follow "istate" but at this stage we are not ready for that: while most git_attr_set_direction() calls just passes the_index to be assigned to use_index, unpack-trees passes a different one which is used by entry.c code, which has no way to know what index to use if we delete use_index. So this has to be done later. Signed-off-by: Nguyễn Thái Ngọc Duy <pclouds@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2017-02-01attr: convert git_all_attrs() to use "struct attr_check"Junio C Hamano
This updates the other two ways the attribute check is done via an array of "struct attr_check_item" elements. These two niches appear only in "git check-attr". * The caller does not know offhand what attributes it wants to ask about and cannot use attr_check_initl() to prepare the attr_check structure. * The caller may not know what attributes it wants to ask at all, and instead wants to learn everything that the given path has. Such a caller can call attr_check_alloc() to allocate an empty attr_check, and then call attr_check_append() to add attribute names one by one.

2017-02-01attr: rename function and struct related to checking attributesJunio C Hamano
The traditional API to check attributes is to prepare an N-element array of "struct git_attr_check" and pass N and the array to the function "git_check_attr()" as arguments. In preparation to revamp the API to pass a single structure, in which these N elements are held, rename the type used for these individual array elements to "struct attr_check_item" and rename the function to "git_check_attrs()".

2016-02-01give "nbuf" strbuf a more meaningful nameJeff King
It's a common pattern in our code to read paths from stdin, separated either by newlines or NULs, and unquote as necessary. In each of these five cases we use "nbuf" to temporarily store the unquoted value. Let's give it the more meaningful name "unquoted", which makes it easier to understand the purpose of the variable. While we're at it, let's also static-initialize all of our strbufs. It's not wrong to call strbuf_init, but it increases the cognitive load on the reader, who might wonder "do we sometimes avoid initializing them? why?".

2016-01-15check-attr: there are only two possible line terminationsJunio C Hamano
The program by default reads LF terminated lines, with an option to use NUL terminated records. Instead of pretending that there can be other useful values for line_termination, use a boolean variable, nul_term_line, to tell if NUL terminated records are used, and switch between strbuf_getline_{lf,nul} based on it.

2015-10-16usage: do not insist that standard input must come from a fileJunio C Hamano
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.

2014-03-14Merge branch 'jc/check-attr-honor-working-tree'Junio C Hamano
"git check-attr" when (trying to) work on a repository with a working tree did not work well when the working tree was specified via --work-tree (and obviously with --git-dir). The command also works in a bare repository but it reads from the (possibly stale, irrelevant and/or nonexistent) index, which may need to be fixed to read from HEAD, but that is a completely separate issue. As a related tangent to this separate issue, we may want to also fix "check-ignore", which refuses to work in a bare repository, to also operate in a bare one. * jc/check-attr-honor-working-tree: check-attr: move to the top of working tree when in non-bare repository t0003: do not chdir the whole test process
2014-02-06check-attr: move to the top of working tree when in non-bare repositoryJunio C Hamano
Lasse Makholm noticed that running "git check-attr" from a place totally unrelated to $GIT_DIR and $GIT_WORK_TREE does not give expected results. I think it is because the command does not say it wants to call setup_work_tree(). We still need to support use cases where only a bare repository is involved, so unconditionally requiring a working tree would not work well. Instead, make a call only in a non-bare repository. We may want to see if we want to do a similar fix in the opposite direction to check-ignore. The command unconditionally requires a working tree, but it should be usable in a bare repository just like check-attr attempts to be. Signed-off-by: Junio C Hamano <gitster@pobox.com>

2011-10-06attr: read core.attributesfile from git_default_core_configJunio C Hamano
This code calls git_config from a helper function to parse the config entry it is interested in. Calling git_config in this way may cause a problem if the helper function can be called after a previous call to git_config by another function since the second call to git_config may reset some variable to the value in the config file which was previously overridden. The above is not a problem in this case since the function passed to git_config only parses one config entry and the variable it sets is not assigned outside of the parsing function. But a programmer who desires all of the standard config options to be parsed may be tempted to modify git_attr_config() so that it falls back to git_default_config() and then it _would_ be vulnerable to the above described behavior. So, move the call to git_config up into the top-level cmd_* function and move the responsibility for parsing core.attributesfile into the main config file parser. Which is only the logical thing to do ;-) Signed-off-by: Brandon Casey <drafnel@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2011-08-04git-check-attr: Normalize pathsMichael Haggerty
Normalize the path arguments (relative to the working tree root, if applicable) before looking up their attributes. This requires passing the prefix down the call chain. This fixes two test cases for different reasons: * "unnormalized paths" is fixed because the .gitattribute-file-seeking code is not confused into reading the top-level file twice. * "relative paths" is fixed because the canonical pathnames are passed to get_check_attr() or get_all_attrs(), allowing them to match the pathname patterns as expected.

2010-02-22Move 'builtin-*' into a 'builtin/' subdirectoryLinus Torvalds
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?

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>
