Andy Wingo be1be3e597 (web http): header names always represented as symbols
* module/web/http.scm (declare-header!): No need to specify `sym', as it
  can be derived from `name'. Change to take parser, validator, and
  writer as positional arguments, and multiple? as a keyword.
  (parse-header): Change to take the header as a symbol already, and
  just return the parsed value.  All headers are symbols now, including
  unknown headers.  I feel OK doing this given that the symbol GC works
  now.
  (lookup-header-decl): Only look up headers by symbol.
  (read-header): Adapt to parse-header change.

  (valid-header?, write-header): Adapt to all headers being symbols.
  (split-header-names, list-of-header-names?, write-header-list):
  Represent all header names as symbols.

  (declare-opaque-header!, declare-date-header!)
  (declare-string-list-header!, declare-header-list-header!)
  (declare-integer-header!, declare-uri-header!)
  (declare-quality-list-header!, declare-param-list-header!)
  (declare-key-value-list-header!, declare-entity-tag-list-header!):
  Change to be functions instead of syntax, and no need to specify the
  symbolic name. Update all header declarations accordingly.

* module/web/request.scm (validate-headers):
* module/web/response.scm (validate-headers): Adapt to all headers being
  symbols.

* test-suite/tests/web-http.test (pass-if-parse, pass-if-any-error)
  (pass-if-parse-error): Update for parse-header change.
  ("general headers"): Update header list examples to be all symbols.

This directory contains some tests for Guile, and some generic test
support code.

To run these tests, you will need a version of Guile more recent than
15 Feb 1999 --- the tests use the (ice-9 and-let*) and (ice-9
getopt-long) modules, which were added to Guile around then.

For information about how to run the test suite, read the usage
instructions in the comments at the top of the guile-test script.

You can reference the file `lib.scm' from your own code as the module
(test-suite lib); it also has comments at the top and before each
function explaining what's going on.

Please write more Guile tests, and send them to bug-guile@gnu.org.
We'll merge them into the distribution.  All test suites must be
licensed for our use under the GPL, but I don't think I'm going to
collect assignment papers for them.



Some test suite philosophy:

GDB has an extensive test suite --- around 6300 tests.  Every time the
test suite catches a bug, it's great.

GDB is so complicated that folks are often unable to get a solid
understanding of the code before making a change --- we just don't
have time.  You'll see people say things like, "Here's a fix for X; it
doesn't cause any regressions."  The subtext is, I made a change that
looks reasonable, and the test suite didn't complain, so it must be
okay.

I think this is terrible, because it suggests that the writer is using
the test suite as a substitute for having a rock-solid explanation of
why their changes are correct.  The problem is that any test suite is
woefully incomplete.  Diligent reasoning about code can catch corner
conditions or limitations that no test suite will ever find.



Jim's rule for test suites:

Every test suite failure should be a complete, mysterious surprise,
never a possibility you were prepared for.  Any other attitude
indicates that you're using the test suite as a crutch, which you need
only because your understanding is weak.
