* introduce hex2chr() for converting two hexadecimal digits to a characterrs/hex2chrRené Scharfe2016-09-071-20/+1
| | | | | | | | | | Add and use a helper function that decodes the char value of two hexadecimal digits. It returns a negative number on error, avoids running over the end of the given string and doesn't shift negative values.

* use strbuf_complete to conditionally append slashJeff King2015-10-051-2/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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).

* Do not unquote + into ' ' in URLsThomas Rast2010-07-251-5/+6
| | | | | | | | | | | | | | | | | Since 9d2e942 (decode file:// and ssh:// URLs, 2010-05-23) the URL logic unquotes escaped URLs. For the %2B type of escape, this is conformant with RFC 2396. However, it also unquotes + into a space character, which is only appropriate for the query strings in HTTP. This notably broke fetching from the gtk+ repository. We cannot just remove the corresponding code since the same url_decode_internal() is also used by the HTTP backend to decode query parameters. Introduce a new argument that controls whether the + decoding happens, and use it only in the (client-side) url_decode().
