quote: add sq_append_quote_argv_pretty()

2019-08-09T17:48:02Z

sq_quote_argv_pretty() builds a "pretty" string from the given argv. It inserts whitespace before each value, rather than just between them, so the resulting string always has a leading space. Lets give callers an option to not have the leading space or have to ltrim() it later. Create sq_append_quote_argv_pretty() to convert an argv into a pretty, quoted if necessary, string with space delimiters and without a leading space. Convert the existing sq_quote_argv_pretty() to use this new routine while preserving the leading space behavior. Signed-off-by: Jeff Hostetler Signed-off-by: Junio C Hamano

*.[ch]: manually align parameter lists

2019-05-05T06:20:10Z

In previous patches, extern was mechanically removed from function declarations without care to formatting, causing parameter lists to be misaligned. Manually format changed sections such that the parameter lists should be realigned. Viewing this patch with 'git diff -w' should produce no output.

*.[ch]: remove extern from function declarations using sed

2019-05-05T06:20:08Z

There has been a push to remove extern from function declarations. Finish the job by removing all instances of "extern" for function declarations in headers using sed. This was done by running the following on my system with sed 4.2.2: $ git ls-files \*.{c,h} | grep -v ^compat/ | xargs sed -i'' -e 's/^$\s*$extern $[^(]*([^*]$/\1\2/' Files under `compat/` are intentionally excluded as some are directly copied from external sources and we should avoid churning them as much as possible. Then, leftover instances of extern were found by running $ git grep -w -C3 extern \*.{c,h} and manually checking the output. No other instances were found. Note that the regex used specifically excludes function variables which _should_ be left as extern. Not the most elegant way to do it but it gets the job done.

*.[ch]: remove extern from function declarations using spatch

2019-05-05T06:20:06Z

There has been a push to remove extern from function declarations. Remove some instances of "extern" for function declarations which are caught by Coccinelle. Note that Coccinelle has some difficulty with processing functions with `__attribute__` or varargs so some `extern` declarations are left behind to be dealt with in a future patch. This was the Coccinelle patch used: @@ type T; identifier f; @@ - extern T f(...); and it was run with: $ git ls-files \*.{c,h} | grep -v ^compat/ | xargs spatch --sp-file contrib/coccinelle/noextern.cocci --in-place Files under `compat/` are intentionally excluded as some are directly copied from external sources and we should avoid churning them as much as possible.

trace: avoid unnecessary quoting

2018-01-16T20:16:54Z

Trace output which contains arbitrary strings (e.g., the arguments to commands which we are running) is always passed through sq_quote_buf(). That function always adds single-quotes, even if the output consists of vanilla characters. This can make the output a bit hard to read. Let's avoid the quoting if there are no characters which a shell would interpret. Trace output doesn't necessarily need to be shell-compatible, but: - the shell language is a good ballpark for what humans consider readable (well, humans versed in command line tools) - the run_command bits can be cut-and-pasted to a shell, and we'll keep that property - it covers any cases which would make the output visually ambiguous (e.g., embedded whitespace or quotes) Signed-off-by: Jeff King Signed-off-by: Nguyễn Thái Ngọc Duy Signed-off-by: Junio C Hamano

sq_quote_argv: drop maxlen parameter

2018-01-16T20:16:54Z

No caller passes anything but "0" for this parameter, which requests that the function ignore it completely. In fact, in all of history there was only one such caller, and it went away in 7f51f8bc2b (alias: use run_command api to execute aliases, 2011-01-07).

grep/icase: avoid kwsset when -F is specified

2016-07-01T19:44:30Z

Similar to the previous commit, we can't use kws on icase search outside ascii range. But we can't simply pass the pattern to regcomp/pcre like the previous commit because it may contain regex special characters, so we need to quote the regex first. To avoid misquote traps that could lead to undefined behavior, we always stick to basic regex engine in this case. We don't need fancy features for grepping a literal string anyway. basic_regex_quote_buf() assumes that if the pattern is in a multibyte encoding, ascii chars must be unambiguously encoded as single bytes. This is true at least for UTF-8. For others, let's wait until people yell up. Chances are nobody uses multibyte, non utf-8 charsets anymore.

ls-tree: remove path filtering logic in show_tree

2014-12-01T19:32:34Z

ls-tree uses read_tree_recursive() which already does path filtering using pathspec. No need to filter one more time based on prefix only. "ls-tree ../somewhere" does not work because of this. write_name_quotedpfx() can now be retired because nobody else uses it. Signed-off-by: Nguyễn Thái Ngọc Duy Signed-off-by: Junio C Hamano
