Summary: debug test failures

Initial Comment:

In a debug build of Tcl (--enable-symbols=all),
a complete `make test` run reliably reports
these failing tests:

==== http11-2.0 -channel FAILED
==== Contents of test case:

    set tok [http::geturl http://localhost:$httpd_port/testdoc.html  -timeout 5000 -channel $chan]
    http::wait $tok
    seek $chan 0
    set data [read $chan]
    list [http::status $tok] [http::code $tok] [check_crc $tok $data] [meta $tok connection] [meta $tok transfer-encoding]

---- Result was:
ok {HTTP/1.1 200 OK} {crc32 mismatch: c554bc27 ne b946628e} close chunked
---- Result should have been (exact matching):
ok {HTTP/1.1 200 OK} ok close chunked
==== http11-2.0 FAILED



==== http11-2.1 -channel, encoding gzip FAILED
==== Contents of test case:

    set tok [http::geturl http://localhost:$httpd_port/testdoc.html  -timeout 5000 -channel $chan -headers {accept-encoding gzip}]
    http::wait $tok
    seek $chan 0
    set data [read $chan]
    list [http::status $tok] [http::code $tok] [check_crc $tok $data] [meta $tok connection] [meta $tok content-encoding] [meta $tok transfer-encoding]

---- Result was:
ok {HTTP/1.1 200 OK} {crc32 mismatch: c554bc27 ne 6d52cc3} close gzip chunked
---- Result should have been (exact matching):
ok {HTTP/1.1 200 OK} ok close gzip chunked
==== http11-2.1 FAILED



==== http11-2.2 -channel, encoding deflate FAILED
==== Contents of test case:

    set tok [http::geturl http://localhost:$httpd_port/testdoc.html  -timeout 5000 -channel $chan -headers {accept-encoding deflate}]
    http::wait $tok
    seek $chan 0
    set data [read $chan]
    list [http::status $tok] [http::code $tok] [check_crc $tok $data] [meta $tok connection] [meta $tok content-encoding] [meta $tok transfer-encoding]

---- Result was:
ok {HTTP/1.1 200 OK} {crc32 mismatch: c554bc27 ne b946628e} close deflate chunked
---- Result should have been (exact matching):
ok {HTTP/1.1 200 OK} ok close deflate chunked
==== http11-2.2 FAILED



==== http11-2.3 -channel,encoding compress FAILED
==== Contents of test case:

    set tok [http::geturl http://localhost:$httpd_port/testdoc.html  -timeout 5000 -channel $chan  -headers {accept-encoding compress}]
    http::wait $tok
    seek $chan 0
    set data [read $chan]
    list [http::status $tok] [http::code $tok] [check_crc $tok $data] [meta $tok connection] [meta $tok content-encoding] [meta $tok transfer-encoding]

---- Result was:
ok {HTTP/1.1 200 OK} {crc32 mismatch: c554bc27 ne ffff1d4} close compress chunked
---- Result should have been (exact matching):
ok {HTTP/1.1 200 OK} ok close compress chunked
==== http11-2.3 FAILED



==== http11-2.10 -channel,deflate,keepalive FAILED
==== Contents of test case:

    set tok [http::geturl http://localhost:$httpd_port/testdoc.html  -timeout 5000 -channel $chan -keepalive 1]
    http::wait $tok
    seek $chan 0
    set data [read $chan]
    list [http::status $tok] [http::code $tok] [check_crc $tok $data] [meta $tok connection] [meta $tok content-encoding] [meta $tok transfer-encoding] [expr {[file size testdoc.html]-[file size testfile.tmp]}]

---- Result was:
ok {HTTP/1.1 200 OK} {crc32 mismatch: c554bc27 ne b946628e} {} deflate chunked 20203
---- Result should have been (exact matching):
ok {HTTP/1.1 200 OK} ok {} deflate chunked 0
==== http11-2.10 FAILED


When "-file http.test" is used to limit the testing to only
that file, the tests pass.

Message:

[$stream add -finalize {}] have different
returns in the FAIL/SUCCEED scenarios.
When the tests fail, the empty string is returned.

Message:
Funnily, the missing part in the write seems to be at the beginning. That
is, the written file is a suffix of the original.
I would hypothesize that the part of the body that is read along with the
headers  gets lost.

Message:

The http::wait commands in these tests
appear pointless since all [geturl] calls
are synchronous (no -command option).

Message:

When the tests fail, the writes to testfile.tmp
are incomplete.

Message:

same failures in a --enable-symbols=mem build.

Message:

Oops!  The failing tests are in http11.test !

Single file testing is enough to see the problem.
