[PATCH 0/5] use starts_with() and ends_with()

[PATCH 0/5] use starts_with() and ends_with()

[Christian Couder]

This is a new patch series along the lines Junio suggested in this
thread:

http://thread.gmane.org/gmane.comp.version-control.git/238054/

I send it now because I saw a 1.8.5 tag.

The patches in this series can be related to what Junio suggested
this way:

 * A set of clean-up patches to normalize oddball usages of existing
   functions (e.g. normalize 'prefixcmp(a,b) != 0' in some file(s)
   to 'prefixcmp(a,b)');

-> Patches 1/5 and 2/5 are such kind of cleanups.

 * A single patch to introduce the new function(s), to be applied on
   top of 1.8.5;

-> Patch 3/5 does that.

 * A large patch to convert all uses of prefixcmp to starts_with and
   suffixcmp to ends_with in the 1.8.5 codebase;

-> Patch 4/5 does that.

 * A patch for each topic in flight to convert newly introduced
   prefixcmp/suffixcmp to starts_with/ends_with, to be applied after
   the topic graduates to 'master' after 1.8.5; and then finally

-> I didn't start to work on that yet. I hope that I will only need
   to take care of what is going on in 'next'.

 * A separate patch to remove prefixcmp and suffixcmp, to be applied
   after _all_ in-flight topic has graduated to 'master'.

-> Patch 5/5 does that.

[PATCH 1/5] environment: normalize use of prefixcmp() by removing " != 0"

[Christian Couder]

To be able to automatically convert prefixcmp() to starts_with()
we need first to make sure that prefixcmp() is always used in
the same way.

So let's remove " != 0" after prefixcmp().

[PATCH 2/5] builtin/remote: remove postfixcmp() and use suffixcmp() instead

[Christian Couder]

Commit 8cc5b290 (git merge -X<option>, 25 Nov 2009) introduced
suffixcmp() with nearly the same implementation as postfixcmp()
that already existed since commit 211c8968 (Make git-remote a
builtin, 29 Feb 2008).

The only difference between the two implementations is that,
when the string is smaller than the suffix, one implementation
returns 1 while the other one returns -1.

But, as postfixcmp() is only used to compare for equality, the
distinction does not matter and does not affect the correctness of
this patch.

As postfixcmp() has always been static in builtin/remote.c
and is used nowhere else, it makes more sense to remove it
and use suffixcmp() instead in builtin/remote.c, rather than
to remove suffixcmp().

[PATCH 3/5] strbuf: introduce starts_with() and ends_with()

[Christian Couder]

prefixcmp() and suffixcmp() cannot be really used as comparison
functions as they are not antisymmetric:

        prefixcmp("foo", "foobar") < 0
        prefixcmp("foobar", "foo") == 0

So they are not suitable as functions for passing to qsort.
And in fact they are used nowhere as comparison functions.

Therefore we should replace them with functions that just check
for equality.

As a first step toward this goal, this patch introduces
starts_with() and end_with() that will be used to replace
respectively prefixcmp() and suffixcmp().

Some popular programming languages, like Java, Python and Ruby
have functions or methods called like starts_with() and
ends_with() that are doing what we want. Therefore it makes sense
to use such names.

In vcs-svn/fast_export.c, there was already an ends_with()
function that did the same thing. Let's use the new one instead
while at it.

This looks sane to me. Your 4/5 did not make it to the list (nor

This made it through to me, but not the list. There are at least two
things going on:

  1. The message is 172K, which is over the 100K limit imposed by vger;
     the list is silently dropping it.

  2. In my case, the direct mail was being flagged by spam because it
     contains the blacklisted domain "old.name". Which of course is not
     a domain at all but rather this code:

       old.name = old.path + strlen("refs/heads/");

     I've tweaked my server.

I can't say why it wasn't getting to Junio via direct mail. Maybe the
same spam thing, or maybe something else.

I skimmed the patch and didn't notice any problems. It's
whitespace-damaged by gmail, of course. The simplest thing is probably
to just point us at a public repo with the commit, if you have one.

Thanks. I looked more carefully this time, using a few greps to classify
the surrounding context (since the script you used for the update could
conceivably miss some really odd misuse). The whole thing looks good to

I looked at the patches, and they looked alright.  The endgame needs
to be on a separate topic to be held until a distant future, though.

Will queue.  Thanks.

It turns out that, naturally, there are many new uses of prefixcmp
in the topics in flight.  I can manage, but adjusting all of them
would not look too pretty X-<.

I can prepare patches for the topics in flight in 'next' for example.

Thanks,

I think the tip of 'pu' with cc/starts-n-ends-with-endgame is in
fairly a good shape.  The evil merge there may need to be updated
over time, but I think I can manage.
