* Package test-only targets as static librariesGravatar Benjamin Barenblat2023-05-08
| | | | | | | | | | | | | | | | | | | | | Abseil 20230125.3 exposes libraries that were formerly internal (“test-only”) so that other packages’ unit tests can refer to them [1]. Some of the new libraries depend on Google Mock, which Debian only ships as a static library; as a result, the new libraries can only be shipped statically as well. Historically, however, Abseil’s Debian packaging has linked Abseil’s unit tests dynamically to improve build speed. (Google Mock was built as a one-off shared library during this process, but it was only ever used in unit tests and was never shipped to users.) Static Abseil builds were unaware that Google Mock existed, which prevented sbuild from building the new libraries [2]. To rectify the situation, change Abseil’s Debian packaging to link Abseil unit tests statically and to ship the new libraries as static archives. Also make libabsl-dev recommend libgmock-dev, since the new libraries are useless without a corresponding Google Mock build.

| * Separate DLL export/import for test helpers dll, and fix typo.Gravatar Mike Kruskal2023-01-25
| | | | | | | | | | | | | | The DLL export issue isn't a problem currently, since we don't explicitly export any symbols from the test dll. This will be an issue in the future though. Additionally, there was a typo in absl_internal_test_dll_contains that caused abseil_test_dll to be empty (and therefore not create a lib file).

There may be such legitimate frames, the default stack size is O(megabytes). Only do this check if we are not within the thread stack bounds.

Given `full_string_crc` and `suffix_crc` (both conditioned CRCs), xoring them together results in: (1): full_string_crc + suffix_crc = UnconditionedCRC(full_string) + StartValue(full_string) + ~0 + UnconditionedCRC(suffix) + StartValue(suffix) + ~0 Since `+` is carry-less addition (ie an XOR), the two ~0 cancel each other out. (2) full_string_crc + suffix_crc = UnconditionedCRC(full_string) + StartValue(full_string) + UnconditionedCRC(suffix) + StartValue(suffix) We can make use of the fact that: (3) UnconditionedCRC(full_string) + UnConditionedCRC(suffix) = UnconditionedCRC(full_string_with_suffix_replaced_by_zeros). Ie, UnconditionedCRC("AABBB") + UnconditionedCRC("BBB") = UnconditionedCRC("AA\0\0\0") Putting (3) into (2) yields: (4) full_string_crc + suffix_crc = UnconditionedCRC(full_string_with_suffix_replaced_by_zeros) + StartValue(full_string) + StartValue(suffix) Using: (5) UnconditionedCRC(full_string_with_suffix_replaced_by_zeros) = UnconditionedCRC(full_string_without_suffix) * x**Bitlength(suffix) mod P and putting (5) into (4) (6) full_string_crc + suffix_crc = UnconditionedCRC(full_string_without_suffix) * x**Bitlength(suffix) mod P + StartValue(full_string) + StartValue(suffix) Using (7) StartValue(full_string) = ~0 * x ** Bitlength(full_string) mod P and (8) StartValue(suffix) = ~0 * x**BitLength(suffix) mod P Putting (7) and (8) in (6): (9): full_string_crc + suffix_crc = UnconditionedCRC(full_string_without_suffix) * x**(Bitlength(suffix)) mod P + ~0 * x ** Bitlength(full_string) mod P + ~0 * x ** BitLength(suffix) mod P Using: (10) Bitlength(full_string) = Bitlength(full_string_without_suffix) + Bitlength(suffix) And putting (10) in (9): (11) full_string_crc + suffix_crc = UnconditionedCRC(full_string_without_suffix) * x**(Bitlength(suffix)) mod P + ~0 * x ** (Bitlength(full_string_without_suffix) + Bitlength(suffix)) mod P + ~0 * x ** BitLength(suffix) mod P using x**(A+B) = x**A * x**B results in: (12) full_string_crc + suffix_crc = UnconditionedCRC(full_string_without_suffix) * x**(Bitlength(suffix)) mod P + [ ~0 * x ** Bitlength(full_string_without_suffix) * x**Bitlength(suffix)] mod P + ~0 * x ** BitLength(suffix) mod P using A mod P + B mod P + C mod P = (A + B + C) mod P: (this works in carry-less arithmetic) (13) full_string_crc + suffix_crc = [ UnconditionedCRC(full_string_without_suffix) * x**(Bitlength(suffix)) + [ ~0 * x ** Bitlength(full_string_without_suffix) * x**Bitlength(suffix)] + ~0 * x ** BitLength(suffix) ] mod P Factor out x**Bitlength(suffix): (14) full_string_crc + suffix_crc = [ x**(Bitlength(suffix)) * [ UnconditionedCRC(full_string_without_suffix) + ~0 * x ** Bitlength(full_string_without_suffix) + ~0 ] mod P Using: (15) ConditionedCRC(full_string_without_suffix) = [ UnconditionedCRC(full_string_without_suffix) + ~0 * x ** Bitlength(full_string_without_suffix) ] mod P + ~0 = [ UnconditionedCRC(full_string_without_suffix) + ~0 * x ** Bitlength(full_string_without_suffix) + ~0] mod P (~0 is less than x**32, so ~0 mod P = ~0) Putting (15) in (14) results in: full_string_crc + suffix_crc = [ x**(Bitlength(suffix)) * ConditionedCRC(full_string_without_suffix)] mod P Or: (16) ConditionedCRC(full_string_without_suffix) = (full_string_crc + suffix_crc) * x**(-Bitlength(suffix)) mod P A multiplication by x**(-8*bytelength) mod P is implemented by `CrcEngine()->UnextendByZeros`.
