2017-11-27Add a new notion of "stamps" to be a fast 32-bit monotonic timestampNick Mathewson
The goal here is to replace our use of msec-based timestamps with something less precise, but easier to calculate. We're doing this because calculating lots of msec-based timestamps requires lots of 64/32 division operations, which can be inefficient on 32-bit platforms. We make sure that these stamps can be calculated using only the coarse monotonic timer and 32-bit bitwise operations.
2017-09-27Move ext_or_command tests to test_proto_misc.cNick Mathewson
No other code changes.
2017-09-05Make preferred_chunk_size nonstatic, and add a prefix to itNick Mathewson
2017-09-05Refactor buffer APIs to put a buf_t first.Nick Mathewson
By convention, a function that frobs a foo_t should be called foo_frob, and it should have a foo_t * as its first argument. But for many of the buf_t functions, the buf_t was the final argument, which is silly.
2017-09-05Repair buffer API so everything starts with buf_.Nick Mathewson
Our convention is that functions which manipulate a type T should be named T_foo. But the buffer functions were super old, and followed all kinds of conventions. Now they're uniform. Here's the perl I used to do this: \#!/usr/bin/perl -w -i -p s/read_to_buf\(/buf_read_from_socket\(/; s/flush_buf\(/buf_flush_to_socket\(/; s/read_to_buf_tls\(/buf_read_from_tls\(/; s/flush_buf_tls\(/buf_flush_to_tls\(/; s/write_to_buf\(/buf_add\(/; s/write_to_buf_compress\(/buf_add_compress\(/; s/move_buf_to_buf\(/buf_move_to_buf\(/; s/peek_from_buf\(/buf_peek\(/; s/fetch_from_buf\(/buf_get_bytes\(/; s/fetch_from_buf_line\(/buf_get_line\(/; s/fetch_from_buf_line\(/buf_get_line\(/; s/buf_remove_from_front\(/buf_drain\(/; s/peek_buf_startswith\(/buf_peek_startswith\(/; s/assert_buf_ok\(/buf_assert_ok\(/;
2017-09-05Move the tls parts of buffers.c into buffers_tls.cNick Mathewson
2017-09-05Make buffers.c independent of or.hNick Mathewson
Also, put ext_or function in new module; it had accidentally gotten into proto_socks.c
2017-09-05Make buf_pullup() expose the pulled-up data.Nick Mathewson
This lets us drop the testing-only function buf_get_first_chunk_data(), and lets us implement proto_http and proto_socks without looking at buf_t internals.
2017-09-05Move protocol-specific functions out of buffers.cNick Mathewson
This commit does not change the implementation of any function: it only moves code and adds new includes as necessary. Part of #23149.
2017-08-24Fix operator usage in src/test/*.cAlexander Færøy
This patch fixes the operator usage in src/test/*.c to use the symbolic operators instead of the normal C comparison operators. This patch was generated using: ./scripts/coccinelle/test-operator-cleanup src/test/*.[ch]
2017-06-21unit tests for peek_buf_startswith()Nick Mathewson
2017-05-02Merge branch 'compress_none_v2_squashed'Nick Mathewson
2017-05-02Add unit tests for the NO_METHOD compressorNick Mathewson
These required some special-casing, since some of the assumption about real compression algorithms don't actually hold for the identity transform. Specifically, we had assumed: - compression functions typically change the lengths of their inputs. - decompression functions can detect truncated inputs - compression functions have detectable headers None of those is true for the identity transformation.
2017-05-01Rename x-lzma to x-tor-lzmaNick Mathewson
We shouldn't call it lzma, because we are imposing a limit on the memory needed for decoding.
2017-04-27Have a separate entry point for each compresion testNick Mathewson
2017-04-27Test support for multiple compression backends in the buffer code.Alexander Færøy
This patch refactors the buffer compression tests to support multiple comprssion backends. See: https://bugs.torproject.org/22085
2017-04-18Rename `write_to_buf_zlib()` to `write_to_buf_compress()`.Alexander Færøy
See https://bugs.torproject.org/21663
2017-04-18Rename `zlib_state` to `compress_state` in the test_buffers.Alexander Færøy
See https://bugs.torproject.org/21663
2017-04-17Refactor the streaming compression code.Alexander Færøy
This patch refactors our streaming compression code to allow us to extend it with non-zlib/non-gzip based compression schemas. See https://bugs.torproject.org/21663
2017-04-17Rename `tor_gzip_{compress,uncompress}` to `tor_{compress,uncompress}`.Alexander Færøy
To allow us to use the API name `tor_compress` and `tor_uncompress` as the main entry-point for all compression/uncompression and not just gzip and zlib. See https://bugs.torproject.org/21663
2017-03-15Run the copyright update script.Nick Mathewson
2017-02-14Don't atoi off the end of a buffer chunk.Nick Mathewson
Fixes bug 20894; bugfix on 0.2.0.16-alpha. We already applied a workaround for this as 20834, so no need to freak out (unless you didn't apply 20384 yet).
2016-09-13Make preferred_chunk_size avoid overflow, handle big inputs betterNick Mathewson
Also, add tests for the function. Closes 20081; bugfix on 0.2.0.16-alpha. This is a Guido Vranken issue. Thanks, Guido!

2016-08-02Remove generic_buffer_*() functions as needless.Nick Mathewson
These functions were there so that we could abstract the differences between evbuffer and buf_t. But with the bufferevent removal, this no longer serves a purpose.
2016-08-02Rename generic_buffer_set_to_copy, since generic buffers are not a thingNick Mathewson
2016-07-28Merge branch 'bug18902_squashed'Nick Mathewson
2016-07-28Fix all -Wshadow warnings on LinuxNick Mathewson
This is a partial fix for 18902.
2016-07-21Use new mock functions in buffer/time_tracking testNick Mathewson
2016-06-11Add -Wmissing-variable-declarations, with attendant fixesNick Mathewson
This is a big-ish patch, but it's very straightforward. Under this clang warning, we're not actually allowed to have a global variable without a previous extern declaration for it. The cases where we violated this rule fall into three roughly equal groups: * Stuff that should have been static. * Stuff that was global but where the extern was local to some other C file. * Stuff that was only global when built for the unit tests, that needed a conditional extern in the headers. The first two were IMO genuine problems; the last is a wart of how we build tests.
2016-02-27Update the copyright year.Nick Mathewson
2015-09-02Remove remaining references to "nulterminate" in commentsNick Mathewson
Thanks to Roger for spotting this!
2015-09-01Remove the unused "nulterminate" option to buf_pullup()Nick Mathewson
I was going to add a test for this, but I realized that it had no users. So, removed.

2015-05-07Merge branch 'writing_tests'Nick Mathewson
2015-05-07Write the outlines of a WritingTests.txt documentNick Mathewson
Also, add some sample tests to be examples.
2015-02-11Remove mempools and buf freelistsNick Mathewson
They have been off-by-default since 0.2.5 and nobody has complained. :) Also remove the buf_shrink() function, which hasn't done anything since we first stopped using contiguous memory to store buffers. Closes ticket 14848.
2015-01-06Merge remote-tracking branch 'public/feature11791'Nick Mathewson
2015-01-02Bump copyright dates to 2015, in case someday this matters.Nick Mathewson
2014-11-17Use smaller zlib objects when under memory pressureNick Mathewson
We add a compression level argument to tor_zlib_new, and use it to determine how much memory to allocate for the zlib object. We use the existing level by default, but shift to smaller levels for small requests when we have been over 3/4 of our memory usage in the past half-hour. Closes ticket 11791.
2014-11-12Fix wide lines (from 13172)Nick Mathewson
2014-11-12Replace operators used as macro arguments with OP_XX macrosNick Mathewson
Part of fix for 13172
2014-10-28Add another year to our copyright dates.Nick Mathewson
Because in 95 years, we or our successors will surely care about enforcing the BSD license terms on this code. Right?
2014-09-15Use coccinelle scripts to clean up our unit testsNick Mathewson
This should get rid of most of the users of the old test_* functions. Some are in macros and will need manual cleanup, though. This patch is for 13119, and was automatically generated with these scripts. The perl scripts are there because coccinelle hates operators as macro arguments. ------------------------------ s/==,/_X_EQ_,/g; s/!=,/_X_NE_,/g; s/<,/_X_LT_,/g; s/>,/_X_GT_,/g; s/>=,/_X_GEQ_,/g; s/<=,/_X_LEQ_,/g; ------------------------------ @@ expression a; identifier func; @@ func (...) { <... -test_fail_msg +TT_DIE ( +( a +) ) ...> } @@ identifier func; @@ func (...) { <... -test_fail() +TT_DIE(("Assertion failed.")) ...> } @@ expression a; identifier func; @@ func (...) { <... -test_assert +tt_assert (a) ...> } @@ expression a, b; identifier func; @@ func (...) { <... -test_eq +tt_int_op (a, +_X_EQ_, b) ...> } @@ expression a, b; identifier func; @@ func (...) { <... -test_neq +tt_int_op (a, +_X_NEQ_, b) ...> } @@ expression a, b; identifier func; @@ func (...) { <... -test_streq +tt_str_op (a, +_X_EQ_, b) ...> } @@ expression a, b; identifier func; @@ func (...) { <... -test_strneq +tt_str_op (a, +_X_NEQ_, b) ...> } @@ expression a, b; identifier func; @@ func (...) { <... -test_eq_ptr +tt_ptr_op (a, +_X_EQ_, b) ...> } @@ expression a, b; identifier func; @@ func() { <... -test_neq_ptr +tt_ptr_op (a, +_X_NEQ_, b) ...> } @@ expression a, b, len; identifier func; @@ func (...) { <... -test_memeq +tt_mem_op (a, +_X_EQ_, b, len) ...> } @@ expression a, b, len; identifier func; @@ func (...) { <... -test_memneq +tt_mem_op (a, +_X_NEQ_, b, len) ...> } ------------------------------ @@ char a, b; identifier func; @@ func (...) { <... -tt_assert +tt_int_op ( -a == b +a, _X_EQ_, b ) ...> } @@ int a, b; identifier func; @@ func (...) { <... -tt_assert +tt_int_op ( -a == b +a, _X_EQ_, b ) ...> } @@ long a, b; identifier func; @@ func (...) { <... -tt_assert +tt_int_op ( -a == b +a, _X_EQ_, b ) ...> } @@ unsigned int a, b; identifier func; @@ func (...) { <... -tt_assert +tt_uint_op ( -a == b +a, _X_EQ_, b ) ...> } @@ unsigned long a, b; identifier func; @@ func (...) { <... -tt_assert +tt_uint_op ( -a == b +a, _X_EQ_, b ) ...> } @@ char a, b; identifier func; @@ func (...) { <... -tt_assert +tt_int_op ( -a != b +a, _X_NEQ_, b ) ...> } @@ int a, b; identifier func; @@ func (...) { <... -tt_assert +tt_int_op ( -a != b +a, _X_NEQ_, b ) ...> } @@ long a, b; identifier func; @@ func (...) { <... -tt_assert +tt_int_op ( -a != b +a, _X_NEQ_, b ) ...> } @@ unsigned int a, b; identifier func; @@ func (...) { <... -tt_assert +tt_uint_op ( -a != b +a, _X_NEQ_, b ) ...> } @@ unsigned long a, b; identifier func; @@ func (...) { <... -tt_assert +tt_uint_op ( -a != b +a, _X_NEQ_, b ) ...> } @@ char a, b; identifier func; @@ func (...) { <... -tt_assert +tt_int_op ( -a >= b +a, _X_GEQ_, b ) ...> } @@ int a, b; identifier func; @@ func (...) { <... -tt_assert +tt_int_op ( -a >= b +a, _X_GEQ_, b ) ...> } @@ long a, b; identifier func; @@ func (...) { <... -tt_assert +tt_int_op ( -a >= b +a, _X_GEQ_, b ) ...> } @@ unsigned int a, b; identifier func; @@ func (...) { <... -tt_assert +tt_uint_op ( -a >= b +a, _X_GEQ_, b ) ...> } @@ unsigned long a, b; identifier func; @@ func (...) { <... -tt_assert +tt_uint_op ( -a >= b +a, _X_GEQ_, b ) ...> } @@ char a, b; identifier func; @@ func (...) { <... -tt_assert +tt_int_op ( -a <= b +a, _X_LEQ_, b ) ...> } @@ int a, b; identifier func; @@ func (...) { <... -tt_assert +tt_int_op ( -a <= b +a, _X_LEQ_, b ) ...> } @@ long a, b; identifier func; @@ func (...) { <... -tt_assert +tt_int_op ( -a <= b +a, _X_LEQ_, b ) ...> } @@ unsigned int a, b; identifier func; @@ func (...) { <... -tt_assert +tt_uint_op ( -a <= b +a, _X_LEQ_, b ) ...> } @@ unsigned long a, b; identifier func; @@ func (...) { <... -tt_assert +tt_uint_op ( -a <= b +a, _X_LEQ_, b ) ...> } @@ char a, b; identifier func; @@ func (...) { <... -tt_assert +tt_int_op ( -a > b +a, _X_GT_, b ) ...> } @@ int a, b; identifier func; @@ func (...) { <... -tt_assert +tt_int_op ( -a > b +a, _X_GT_, b ) ...> } @@ long a, b; identifier func; @@ func (...) { <... -tt_assert +tt_int_op ( -a > b +a, _X_GT_, b ) ...> } @@ unsigned int a, b; identifier func; @@ func (...) { <... -tt_assert +tt_uint_op ( -a > b +a, _X_GT_, b ) ...> } @@ unsigned long a, b; identifier func; @@ func (...) { <... -tt_assert +tt_uint_op ( -a > b +a, _X_GT_, b ) ...> } @@ char a, b; identifier func; @@ func (...) { <... -tt_assert +tt_int_op ( -a < b +a, _X_LT_, b ) ...> } @@ int a, b; identifier func; @@ func (...) { <... -tt_assert +tt_int_op ( -a < b +a, _X_LT_, b ) ...> } @@ long a, b; identifier func; @@ func (...) { <... -tt_assert +tt_int_op ( -a < b +a, _X_LT_, b ) ...> } @@ unsigned int a, b; identifier func; @@ func (...) { <... -tt_assert +tt_uint_op ( -a < b +a, _X_LT_, b ) ...> } @@ unsigned long a, b; identifier func; @@ func (...) { <... -tt_assert +tt_uint_op ( -a < b +a, _X_LT_, b ) ...> } ------------------------------ s/_X_NEQ_/!=/g; s/_X_NE_/!=/g; s/_X_EQ_/==/g; s/_X_GT_/>/g; s/_X_LT_/</g; s/_X_GEQ_/>=/g; s/_X_LEQ_/<=/g; s/test_mem_op\(/tt_mem_op\(/g;

These are actually tests for #311. It appears to me that we didn't fix #311 properly when we thought we did in 475eb5d6; instead, the real fix was 05eff35ac6d64b, a few minutes earlier.
