attr: move doc to attr.h

2019-11-18T06:21:28Z

Move the documentation from Documentation/technical/api-gitattributes.txt to attr.h as it's easier for the developers to find the usage information beside the code instead of looking for it in another doc file. Also documentation/technical/api-gitattributes.txt is removed because the information it has is now redundant and it'll be hard to keep it up to date and synchronized with the documentation in the header file.

Make git_check_attr() a void function

2018-09-12T22:15:34Z

git_check_attr() returns always 0. Remove all the error handling code of the callers, which is never executed. Change git_check_attr() to be a void function. Signed-off-by: Torsten Bögershausen Signed-off-by: Junio C Hamano

Merge branch 'en/incl-forward-decl'

2018-08-20T19:41:32Z

Code hygiene improvement for the header files. * en/incl-forward-decl: Remove forward declaration of an enum compat/precompose_utf8.h: use more common include guard style urlmatch.h: fix include guard Move definition of enum branch_track from cache.h to branch.h alloc: make allocate_alloc_state and clear_alloc_state more consistent Add missing includes and forward declarations

Add missing includes and forward declarations

I looped over the toplevel header files, creating a temporary two-line C program for each consisting of #include "git-compat-util.h" #include $HEADER This patch is the result of manually fixing errors in compiling those tiny programs. Signed-off-by: Elijah Newren Signed-off-by: Junio C Hamano

attr: remove index from git_attr_set_direction()

2018-08-13T21:14:43Z

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.

attr: remove an implicit dependency on the_index

2018-08-13T21:14:42Z

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 Signed-off-by: Junio C Hamano

pathspec: allow querying for attributes

2017-03-13T22:28:54Z

The pathspec mechanism is extended via the new ":(attr:eol=input)pattern/to/match" syntax to filter paths so that it requires paths to not just match the given pattern but also have the specified attrs attached for them to be chosen.

attr: reformat git_attr_set_direction() function

2017-02-01T21:46:53Z

Move the 'git_attr_set_direction()' up to be closer to the variables that it modifies as well as a small formatting by renaming the variable 'new' to 'new_direction' so that it is more descriptive. Update the comment about how 'direction' is used to read the state of the world. It should be noted that callers of 'git_attr_set_direction()' should ensure that other threads are not making calls into the attribute system until after the call to 'git_attr_set_direction()' completes. This function essentially acts as reset button for the attribute system and should be handled with care. Signed-off-by: Brandon Williams Signed-off-by: Junio C Hamano

attr: store attribute stack in attr_check structure

2017-02-01T21:46:53Z

The last big hurdle towards a thread-safe API for the attribute system is the reliance on a global attribute stack that is modified during each call into the attribute system. This patch removes this global stack and instead a stack is stored locally in each attr_check instance. This opens up the opportunity for future optimizations to customize the attribute stack for the attributes that a particular attr_check struct is interested in. One caveat with pushing the attribute stack into the attr_check structure is that the attribute system now needs to keep track of all active attr_check instances. Due to the direction mechanism the stack needs to be dropped when the direction is switched. In order to ensure correctness when the direction is changed the attribute system needs to iterate through all active attr_check instances and drop each of their stacks.
