[PATCH v6 0/7] Rewrite `git_config()` using config-set API

2014-07-31 Thread Tanay Abhra
[Patch v6]: Added _() to error messages.
Diff between v6 and v4 at the bottom.

[PATCH v5]: New patch added (3/7). git_config() now returns void.

[PATCH v4]: One style nit corrected, also added key to error messages.

[PATCH V3]:All the suggestions in [3] applied. Built on top of [1].

[PATCH V2]: All the suggestions in [2] incorporated. git_config() now follows
correct parsing order. Reordered the patches. Removed xfuncname patch
as it was unnecssary.

This series builds on the top of topic[1] in the mailing list with name
git config cache  special querying API utilizing the cache.

This series aims to do these three things,

* Use the config-set API to rewrite git_config().

* Solve any legacy bugs in the previous system while at it.

* To be feature complete compared to the previous git_config() implementation,
  which I think it is now. (added the line number and file name info just for
  completeness)

Also, I haven't yet checked the exact improvements but still as a teaser,
git status now only rereads the configuration files twice instead of four
times.

Tanay Abhra (7):
  config.c: fix accuracy of line number in errors
  add line number and file name info to `config_set`
  change `git_config()` return value to void
  rewrite git_config() to use the config-set API
  add a test for semantic errors in config files
  config: add `git_die_config()` to the config-set API
  add tests for `git_config_get_string_const()`

Except for the tiny style issue in PATCH 6, the series is now
