2012-12-13index-format.txt: clarify what is "invalid"Libravatar Nguyễn Thái Ngọc Duy1-2/+3
A cache-tree entry with a negative entry count is considered invalid by the current Git; it records that we do not know the object name of a tree that would result by writing the directory covered by the cache-tree as a tree object. Clarify that any entry with a negative entry count is invalid, but the implementations must write -1 there. This way, we can later decide to allow writers to use negative values other than -1 to encode optional information on such invalidated entries without harming interoperability; we do not know what will be encoded and how, so we keep these other negative values as reserved for now.

2012-10-29string_list_longest_prefix(): remove functionLibravatar Michael Haggerty1-8/+0
This function was added in f103f95b11d087f07c0c48bf784cd9197e18f203 in the erroneous expectation that it would be used in the reimplementation of longest_ancestor_length(). But it turned out to be easier to use a function specialized for comparing path prefixes (i.e., one that knows about slashes and root paths) than to prepare the paths in such a way that a generic string prefix comparison function can be used. So delete string_list_longest_prefix() and its documentation and test cases. Signed-off-by: Michael Haggerty <mhagger@alum.mit.edu> Signed-off-by: Jeff King <peff@peff.net>

2012-09-18string_list API: document what "sorted" meansLibravatar Michael Haggerty1-3/+4

2012-09-12string_list: add two new functions for splitting stringsLibravatar Michael Haggerty1-1/+21
Add two new functions, string_list_split() and string_list_split_in_place(). These split a string into a string_list on a separator character. The first makes copies of the substrings (leaving the input string untouched) and the second splits the original string in place, overwriting the separator characters with NULs and referring to the original string's memory. These functions are similar to the strbuf_split_*() functions except that they work with the more powerful string_list interface.

2012-09-02argv-array: add pop functionLibravatar Jeff King1-0/+4
Sometimes we build a set of similar command lines, differing only in the final arguments (e.g., "fetch --multiple"). To use argv_array for this, you have to either push the same set of elements repeatedly, or break the abstraction by manually manipulating the array's internal members. Instead, let's provide a sanctioned "pop" function to remove elements from the end. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>

Finishing touches... * mm/api-credentials-doc: docs: fix cross-directory linkgit references
2012-06-08docs: fix cross-directory linkgit referencesLibravatar Jeff King3-5/+5
Most of our documentation is in a single directory, so using linkgit:git-config[1] just generates a relative link in the same directory. However, this is not the case with the API documentation in technical/*, which need to refer to git-config from the parent directory. We can fix this by passing a special prefix attribute when building in a subdirectory, and respecting that prefix in our linkgit definitions. We only have to modify the html linkgit definition. For manpages, we can ignore this for two reasons: 1. we do not generate actual links to the file in manpages, but instead just give the name and section of the linked manpage 2. we do not currently build manpages for subdirectories, only html Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Matthieu Moy <Matthieu.Moy@imag.fr> Signed-off-by: Junio C Hamano <gitster@pobox.com>
