2017-07-12Reformat and sort all includes with clang-formatJulian Andres Klode
This makes it easier to see which headers includes what. The changes were done by running git grep -l '#\s*include' \ | grep -E '.(cc|h)$' \ | xargs sed -i -E 's/(^\s*)#(\s*)include/\1#\2 include/' To modify all include lines by adding a space, and then running ./git-clang-format.sh.

2016-07-06report all instead of first error up the acquire chainDavid Kalnischkies
If we don't give a specific error to report up it is likely that all error currently in the error stack are equally important, so reporting just one could turn out to be confusing e.g. if name resolution failed in a SRV record list.
2016-07-02use +0000 instead of UTC by default as timezone in outputDavid Kalnischkies
All apt versions support numeric as well as 3-character timezones just fine and its actually hard to write code which doesn't "accidently" accepts it. So why change? Documenting the Date/Valid-Until fields in the Release file is easy to do in terms of referencing the datetime format used e.g. in the Debian changelogs (policy §4.4). This format specifies only the numeric timezones through, not the nowadays obsolete 3-character ones, so in the interest of least surprise we should use the same format even through it carries a small risk of regression in other clients (which encounter repositories created with apt-ftparchive). In case it is really regressing in practice, the hidden option -o APT::FTPArchive::Release::NumericTimezone=0 can be used to go back to good old UTC as timezone. The EDSP and EIPP protocols use this 'new' format, the text interface used to communicate with the acquire methods does not for compatibility reasons even if none of our methods would be effected and I doubt any other would (in these instances the timezone is 'GMT' as that is what HTTP/1.1 requires). Note that this is only true for apt talking to methods, (libapt-based) methods talking to apt will respond with the 'new' format. It is therefore strongly adviced to support both also in method input.
2016-05-27prevent C++ locale number formatting in text APIsDavid Kalnischkies
Setting the C++ locale via std::locale::global(std::locale("")); which would otherwise default to the default C locale (aka: unaffected by setlocale) effects the formatting of numeric types in IO streams, which for output for humans is perfectly sensible, but breaks our many text interfaces used and parsed by us and others without expecting the numbers to be formatted. Closes: #825396

2015-08-10make all d-pointer * const pointersDavid Kalnischkies
Doing this disables the implicit copy assignment operator (among others) which would cause hovac if used on the classes as it would just copy the pointer, not the data the d-pointer points to. For most of the classes we don't need a copy assignment operator anyway and in many classes it was broken before as many contain a pointer of some sort. Only for our Cacheset Container interfaces we define an explicit copy assignment operator which could later be implemented to copy the data from one d-pointer to the other if we need it. Git-Dch: Ignore
2015-06-16add d-pointer, virtual destructors and de-inline de/constructorsDavid Kalnischkies
To have a chance to keep the ABI for a while we need all three to team up. One of them missing and we might loose, so ensuring that they are available is a very tedious but needed task once in a while. Git-Dch: Ignore
2015-06-09check patch hashes in rred worker instead of in the handlerDavid Kalnischkies
rred is responsible for unpacking and reading the patch files in one go, but we currently only have hashes for the uncompressed patch files, so the handler read the entire patch file before dispatching it to the worker which would read it again – both with an implicit uncompress. Worse, while the workers operate in parallel the handler is the central orchestration unit, so having it busy with work means the workers do (potentially) nothing. This means rred is working with 'untrusted' data, which is bad. Yet, having the unpack in the handler meant that the untrusted uncompress was done as root which isn't better either. Now, we have it at least contained in a binary which we can harden a bit better. In the long run, we want hashes for the compressed patch files through to be safe.
2015-06-09rework hashsum verification in the acquire systemDavid Kalnischkies
Having every item having its own code to verify the file(s) it handles is an errorprune process and easy to break, especially if items move through various stages (download, uncompress, patching, …). With a giant rework we centralize (most of) the verification to have a better enforcement rate and (hopefully) less chance for bugs, but it breaks the ABI bigtime in exchange – and as we break it anyway, it is broken even harder. It shouldn't effect most frontends as they don't deal with the acquire system at all or implement their own items, but some do and will need to be patched (might be an opportunity to use apt on-board material). The theory is simple: Items implement methods to decide if hashes need to be checked (in this stage) and to return the expected hashes for this item (in this stage). The verification itself is done in worker message passing which has the benefit that a hashsum error is now a proper error for the acquire system rather than a Done() which is later revised to a Failed().
2014-10-13do not inline virtual destructors with d-pointersDavid Kalnischkies
Reimplementing an inline method is opening a can of worms we don't want to open if we ever want to us a d-pointer in those classes, so we do the only thing which can save us from hell: move the destructors into the cc sources and we are good. Technically not an ABI break as the methods inline or not do the same (nothing), so a program compiled against the old version still works with the new version (beside that this version is still in experimental, so nothing really has been build against this library anyway).

2014-10-07do not show IP in output of testcasesDavid Kalnischkies
On travis-ci connect.cc detects a rotation, triggering it store the IP which is later appended to the error message, which is all nice and great if we deal with a real server, but in the testcases it just triggers failures as strings do not match. Git-Dch: Ignore

2014-05-09tell download methods the expected hashesDavid Kalnischkies
Now that we have all hashes in the acquire system, pass the info down to the methods, so that it can use it in the request and/or to precheck the response.
2014-05-09use HashStringList in the acquire systemDavid Kalnischkies
It is not very extensible to have the supported Hashes hardcoded everywhere and especially if it is part of virtual method names. It is also possible that a method does not support the 'best' hash (yet), so we might end up not being able to verify a file even though we have a common subset of supported hashes. And those are just two of the cases in which it is handy to have a more dynamic selection. The downside is that this is a MAJOR API break, but the HashStringList has a string constructor for compatibility, so with a bit of luck the few frontends playing with the acquire system directly are okay.
