* rs/cocci-strbuf-addf-to-addstr:
cocci: simplify check for trivial format strings
|
|
353d84c537 (coccicheck: make transformation for strbuf_addf(sb, "...")
more precise) added a check to avoid transforming calls with format
strings which contain percent signs, as that would change the result.
It uses embedded Python code for that. Simplify this rule by using the
regular expression matching operator instead.

There's a rule in strbuf.cocci for converting trivial uses of
strbuf_addf() to strbuf_addstr() in order to simplify the code and
improve performance a bit. Coccinelle 1.0.0~rc19.deb-3 on Travis CI
lets the "%s" in that rule match format strings like "%d" as well for
some reason, though, leading to invalid proposed patches.
Use the "format" keyword to let Coccinelle parse the format string and
match the conversion specifier with a trivial regular expression
instead. This works fine with both Coccinelle 1.0.0~rc19.deb-3 and
1.0.4.deb-3+b3 (the current version on Debian testing).

Add a function for appending the canonized absolute pathname of a given
path to a strbuf. It keeps the existing contents intact, as expected of
a function of the strbuf_add() family, while avoiding copying the result
if the given strbuf is empty. It's more consistent with the rest of the
strbuf API than strbuf_realpath(), which it's wrapping.
Also add a semantic patch demonstrating its intended usage and apply it
to the current tree. Using strbuf_add_real_path() instead of calling
strbuf_addstr() and real_path() avoids an extra copy to a static buffer.

We can replace strbuf_addf() calls that just add a simple string with
calls to strbuf_addstr() to make the intent clearer. We need to be
careful if that string contains printf format specifications like %%,
though, as a simple replacement would change the output.
Add checks to the semantic patch to make sure we only perform the
transformation if the second argument is a string constant (possibly
translated) that doesn't contain any percent signs.

Call strbuf_add_unique_abbrev() to add abbreviated hashes to strbufs
instead of taking detours through find_unique_abbrev() and its static
buffer. This is shorter and a bit more efficient.
1eb47f167d65d1d305b9c196a1bb40eb96117cb1 already converted six cases,
this patch covers three more.
A semantic patch for Coccinelle is included for easier checking for
new cases that might be introduced in the future.
