strbuf: give URL-encoding API a char predicate fn

2019-06-28T15:41:53Z

Allow callers to specify exactly what characters need to be URL-encoded and which do not. This new API will be taken advantage of in a patch later in this set. Helped-by: Jeff King Signed-off-by: Matthew DeVore Signed-off-by: Junio C Hamano

path.c: and an option to call real_path() in expand_user_path()

2017-04-15T06:51:38Z

In the next patch we need the ability to expand '~' to real_path($HOME). But we can't do that from outside because '~' is part of a pattern, not a true path. Add an option to expand_user_path() to do so. Signed-off-by: Nguyễn Thái Ngọc Duy Signed-off-by: Junio C Hamano

add an extra level of indirection to main()

2016-07-01T22:09:10Z

There are certain startup tasks that we expect every git process to do. In some cases this is just to improve the quality of the program (e.g., setting up gettext()). In others it is a requirement for using certain functions in libgit.a (e.g., system_path() expects that you have called git_extract_argv0_path()). Most commands are builtins and are covered by the git.c version of main(). However, there are still a few external commands that use their own main(). Each of these has to remember to include the correct startup sequence, and we are not always consistent. Rather than just fix the inconsistencies, let's make this harder to get wrong by providing a common main() that can run this standard startup. We basically have two options to do this: - the compat/mingw.h file already does something like this by adding a #define that replaces the definition of main with a wrapper that calls mingw_startup(). The upside is that the code in each program doesn't need to be changed at all; it's rewritten on the fly by the preprocessor. The downside is that it may make debugging of the startup sequence a bit more confusing, as the preprocessor is quietly inserting new code. - the builtin functions are all of the form cmd_foo(), and git.c's main() calls them. This is much more explicit, which may make things more obvious to somebody reading the code. It's also more flexible (because of course we have to figure out _which_ cmd_foo() to call). The downside is that each of the builtins must define cmd_foo(), instead of just main(). This patch chooses the latter option, preferring the more explicit approach, even though it is more invasive. We introduce a new file common-main.c, with the "real" main. It expects to call cmd_main() from whatever other objects it is linked against. We link common-main.o against anything that links against libgit.a, since we know that such programs will need to do this setup. Note that common-main.o can't actually go inside libgit.a, as the linker would not pick up its main() function automatically (it has no callers). The rest of the patch is just adjusting all of the various external programs (mostly in t/helper) to use cmd_main(). I've provided a global declaration for cmd_main(), which means that all of the programs also need to match its signature. In particular, many functions need to switch to "const char **" instead of "char **" for argv. This effect ripples out to a few other variables and functions, as well. This makes the patch even more invasive, but the end result is much better. We should be treating argv strings as const anyway, and now all programs conform to the same signature (which also matches the way builtins are defined).

strbuf: introduce strbuf_getline_{lf,nul}()

2016-01-15T18:12:51Z

The strbuf_getline() interface allows a byte other than LF or NUL as the line terminator, but this is only because I wrote these codepaths anticipating that there might be a value other than NUL and LF that could be useful when I introduced line_termination long time ago. No useful caller that uses other value has emerged. By now, it is clear that the interface is overly broad without a good reason. Many codepaths have hardcoded preference to read either LF terminated or NUL terminated records from their input, and then call strbuf_getline() with LF or NUL as the third parameter. This step introduces two thin wrappers around strbuf_getline(), namely, strbuf_getline_lf() and strbuf_getline_nul(), and mechanically rewrites these call sites to call either one of them. The changes contained in this patch are: * introduction of these two functions in strbuf.[ch] * mechanical conversion of all callers to strbuf_getline() with either '\n' or '\0' as the third parameter to instead call the respective thin wrapper. After this step, output from "git grep 'strbuf_getline('" would become a lot smaller. An interim goal of this series is to make this an empty set, so that we can have strbuf_getline_crlf() take over the shorter name strbuf_getline(). Signed-off-by: Junio C Hamano

Make error message after failing commit_lock_file() less confusing

2015-12-01T23:17:23Z

The error message after a failing commit_lock_file() call sometimes looks like this, causing confusion: $ git remote add remote git@server.com/repo.git error: could not commit config file .git/config # Huh?! # I didn't want to commit anything, especially not my config file! While in the narrow context of the lockfile module using the verb 'commit' in the error message makes perfect sense, in the broader context of git the word 'commit' already has a very specific meaning, hence the confusion. Reword these error messages to say "could not write" instead of "could not commit". While at it, include strerror in the error messages after writing the config file or the credential store fails to provide some information about the cause of the failure, and update the style of the error message after writing the reflog fails to match surrounding error messages (i.e. no '' around the pathname and no () around the error description).

lockfile: add accessors get_lock_file_fd() and get_lock_file_fp()
