0e09706844 util: add note about event file descriptors on Windows
When using GNULIB with Winsock, libvirt will never see the normal HANDLE
objects, instead GNULIB guarantees that libvirt gets a C runtime file
descriptor. The GNULIB poll impl also expects to get C runtime file
descriptors rather than HANDLE objects. Document this behaviour so that
it is clear to applications providing event loop implementations if they
need Windows portability.

d5c5d8af45 python: mark regex strings with 'r' prefix
When writing regexes special regex matches like "\d" can get
misinterpreted as normal string escape sequences:

docs/apibuild.py:1359:51: W605 invalid escape sequence '\d'

docs/apibuild.py:2134:31: W605 invalid escape sequence '\('
                m = re.match("\(?1<<(\d+)\)?", info[0])
                              ^
docs/apibuild.py:2134:38: W605 invalid escape sequence '\d'
                m = re.match("\(?1<<(\d+)\)?", info[0])
                                     ^
docs/apibuild.py:2134:42: W605 invalid escape sequence '\)'
                m = re.match("\(?1<<(\d+)\)?", info[0])
                                         ^

To avoid this probem all regexes should use the r"...." syntax for their
strings, which disables normal string escape sequences.

3a5fea6062 build: change flake8 to use blacklist instead of whitelist
The current flake8 check only looks at one item (semicolons at end of
line). This means that our code quality will continue to get worse,
violating an increasing number of checks.

Switching to a whitelist means that we freeze the badness at its
current level & can incrementally fix things up.

We are excluding the following...

Indentation:

  E114 indentation is not a multiple of four (comment)
  E115 expected an indented block (comment)
  E116 unexpected indentation (comment)
  E121 continuation line under-indented for hanging indent
  E125 continuation line with same indent as next logical line
  E126 continuation line over-indented for hanging indent
  E127 continuation line over-indented for visual indent
  E128 continuation line under-indented for visual indent
  E129 visually indented line with same indent as next logical line
  E131 continuation line unaligned for hanging indent

Whitespace:

  E211 whitespace before ‘(‘
  E221 multiple spaces before operator
  E222 multiple spaces after operator
  E225 missing whitespace around operator
  E226 missing whitespace around arithmetic operator
  E231 missing whitespace after ‘,’, ‘;’, or ‘:’
  E261 at least two spaces before inline comment

Blank lines

  E301 expected 1 blank line, found 0
  E302 expected 2 blank lines, found 0
  E303 too many blank lines (3)
  E305 expected 2 blank lines after end of function or class

Line length

  E501 line too long (82 > 79 characters)

Statements

  E722 do not use bare except, specify exception instead
  E741 do not use variables named ‘l’, ‘O’, or ‘I’

Errors:

  F821 undefined name 'name'

Warnings:

  W504 line break after binary operator
  W605 invalid escape sequence ‘x’

Later commits will enable most of these exclusions.

44e7f02915 util: rewrite auto cleanup macros to use glib's equivalent
To facilitate porting over to glib, this rewrites the auto cleanup
macros to use glib's equivalent.

As a result it is now possible to use g_autoptr/VIR_AUTOPTR, and
g_auto/VIR_AUTOCLEAN, g_autofree/VIR_AUTOFREE interchangably, regardless
of which macros were used to declare the cleanup types.

Within the scope of any single method, code must remain consistent
using either GLib or Libvirt macros, never mixing both. New code
must preferentially use the GLib macros, and old code will be
converted incrementally.

ff376c6283 tests: fix mocking of stat() / lstat() functions
Quite a few of the tests have a need to mock the stat() / lstat()
functions and they are taking somewhat different & inconsistent
approaches none of which are actually fully correct. This is shown
by fact that 'make check' fails on 32-bit hosts. Investigation
revealed that the code was calling into the native C library impl,
not getting intercepted by our mocks.

The POSIX stat() function might resolve to any number of different
symbols in the C library.

The may be an additional stat64() function exposed by the headers
too.

On 64-bit hosts the stat & stat64 functions are identical, always
refering to the 64-bit ABI.

On 32-bit hosts they refer to the 32-bit & 64-bit ABIs respectively.

Libvirt uses _FILE_OFFSET_BITS=64 on 32-bit hosts, which causes the
C library to transparently rewrite stat() calls to be stat64() calls.
Libvirt will never see the 32-bit ABI from the traditional stat()
call. We cannot assume this rewriting is done using a macro. It might
be, but on GLibC it is done with a magic __asm__ statement to apply
the rewrite at link time instead of at preprocessing.

In GLibC there may be two additional functions exposed by the headers,
__xstat() and __xstat64(). When these exist, stat() and stat64() are
transparently rewritten to call __xstat() and __xstat64() respectively.
The former symbols will not actally exist in the library at all, only
the header. The leading "__" indicates the symbols are a private impl
detail of the C library that applications should not care about.
Unfortunately, because we are trying to mock replace the C library,
we need to know about this internal impl detail.

With all this in mind the list of functions we have to mock will depend
on several factors

 - If _FILE_OFFSET_BITS is set, then we are on a 32-bit host, and we
   only need to mock stat64 and __xstat64. The other stat / __xstat
   functions exist, but we'll never call them so they can be ignored
   for mocking.

 - If _FILE_OFFSET_BITS is not set, then we are on a 64-bit host and
   we should mock stat, stat64, __xstat & __xstat64. Either may be
   called by app code.

 - If __xstat & __xstat64 exist, then stat & stat64 will not exist
   as symbols in the library, so the latter should not be mocked.

The same all applies to lstat()

These rules are complex enough that we don't want to duplicate them
across every mock file, so this centralizes all the logic in a helper
file virmockstathelper.c that should be #included when needed. The
code merely need to provide a filename rewriting callback called
virMockStatRedirect(). Optionally VIR_MOCK_STAT_HOOK can be defined
as a macro if further processing is needed inline.

600462834f Remove all Author(s): lines from source file headers
In many files there are header comments that contain an Author:
statement, supposedly reflecting who originally wrote the code.
In a large collaborative project like libvirt, any non-trivial
file will have been modified by a large number of different
contributors. IOW, the Author: comments are quickly out of date,
omitting people who have made significant contribitions.

In some places Author: lines have been added despite the person
merely being responsible for creating the file by moving existing
code out of another file. IOW, the Author: lines give an incorrect
record of authorship.

With this all in mind, the comments are useless as a means to identify
who to talk to about code in a particular file. Contributors will always
be better off using 'git log' and 'git blame' if they need to  find the
author of a particular bit of code.

This commit thus deletes all Author: comments from the source and adds
a rule to prevent them reappearing.

The Copyright headers are similarly misleading and inaccurate, however,
we cannot delete these as they have legal meaning, despite being largely
inaccurate. In addition only the copyright holder is permitted to change
their respective copyright statement.

a3857dbeeb po: minimize & canonicalize translations stored in git
Similar to the libvirt.pot, .po files contain line numbers and file
names identifying where in the source a translatable string comes from.
The source locations in the .po files are thrown away and replaced with
content from the libvirt.pot whenever msgmerge is run, so this is not
precious information that needs to be stored in git.

When msgmerge processes a .po file, it will add in any msgids from the
libvirt.pot that were not already present. Thus, if a particular msgid
currently has no translation, it can be considered redundant and again
does not need storing in git.

When msgmerge processes a .po file and can't find an exact existing
translation match, it will try todo fuzzy matching instead, marking such
entries with a "# fuzzy" comment to alert the translator to take a
look and either discard, edit or accept the match. Looking at the
existing fuzzy matches in .po files shows that the quality is awful,
with many having a completely different set of printf format specifiers
between the msgid and fuzzy msgstr entry. Fortunately when msgfmt
generates the .gmo, the fuzzy entries are all ignored anyway. The fuzzy
entries could be useful to translators if they were working on the .po
files directly from git, but Libvirt outsourced translation to the
Fedora Zanata system, so keeping fuzzy matches in git is not much help.

Finally, by default msgids are sorted based on source location. Thus, if
a bit of code with translatable text is moved from one file to another,
it may shift around in the .po file, despite the msgid not itself changing.
If the msgids were sorted alphabetically, the .po files would have
stable ordering when code is refactored.

This patch takes advantage of the above observations to canonicalize
and minimize the content stored for .po files in git. Instead of storing
the real .po files, we now store .mini.po files.

The .mini.po files are the same file format as .po files, but have no
source location comments, are sorted alphabetically, and all fuzzy
msgstrs and msgids with no translation are discarded. This cuts the size
of content in the po directory from 109MB to 19MB.

Users working from a libvirt git checkout who need the full .po files
can run "make update-po", which merges the libvirt.pot and .mini.po
file to create a .po file containing all the content previously stored
in git.

Conversely if a full .po file has been modified, for example, by
downloading new content from Zanata, the .mini.po files can be updated
by running "make update-mini-po". The resulting diffs of the .mini.po
file will clearly show the changed translations without any of the noise
that previously obscured content. Being able to see content changes
clearly actually identified a bug in the zanata python client where it
was adding bogus "fuzzy" annotations to many messages:

  https://bugzilla.redhat.com/show_bug.cgi?id=1564497

Users working from libvirt releases should not see any difference in
behaviour, since the tarballs only contain the full .po files, not the
.mini.po files.

As an added benefit, generating tarballs with "make dist", will no
longer cause creation of dirty files in git, since it won't touch the
.mini.po files, only the .po files which are no longer kept in git.

To avoid creating a single commit 100+MB in size, each language is
minimized separately in a following commit.

407a281a8e Revert "Prevent more compiler optimization of mockable functions"
This reverts commit e4b980c853.

When a binary links against a .a archive (as opposed to a shared library),
any symbols which are marked as 'weak' get silently dropped. As a result
when the binary later runs, those 'weak' functions have an address of
0x0 and thus crash when run.

This happened with virtlogd and virtlockd because they don't link to
libvirt.so, but instead just libvirt_util.a and libvirt_rpc.a. The
virRandomBits symbols was weak and so left out of the virtlogd &
virtlockd binaries, despite being required by virHashTable functions.

Various other binaries like libvirt_lxc, libvirt_iohelper, etc also
link directly to .a files instead of libvirt.so, so are potentially
at risk of dropping symbols leading to a later runtime crash.

This is normal linker behaviour because a weak symbol is not treated
as undefined, so nothing forces it to be pulled in from the .a You
have to force the linker to pull in weak symbols using -u$SYMNAME
which is not a practical approach.

This risk is silent bad linkage that affects runtime behaviour is
not acceptable for a fix that was merely trying to fix the test
suite. So stop using __weak__ again.

e4b980c853 Prevent more compiler optimization of mockable functions
Currently all mockable functions are annotated with the 'noinline'
attribute. This is insufficient to guarantee that a function can
be reliably mocked with an LD_PRELOAD. The C language spec allows
the compiler to assume there is only a single implementation of
each function. It can thus do things like propagating constant
return values into the caller at compile time, or creating
multiple specialized copies of the function body each optimized
for a different caller. To prevent these optimizations we must
also set the 'noclone' and 'weak' attributes.

This fixes the test suite when libvirt.so is built with CLang
with optimization enabled.

728cacc8ab annotate all mocked functions with noinline
CLang's optimizer is more aggressive at inlining functions than
gcc and so will often inline functions that our tests want to
mock-override. This causes the test to fail in bizarre ways.

We don't want to disable inlining completely, but we must at
least prevent inlining of mocked functions. Fortunately there
is a 'noinline' attribute that lets us control this per function.

A syntax check rule is added that parses tests/*mock.c to extract
the list of functions that are mocked (restricted to names starting
with 'vir' prefix). It then checks that src/*.h header file to
ensure it has a 'ATTRIBUTE_NOINLINE' annotation. This should prevent
use from bit-rotting in future.

cc9c62fef9 Require spaces around equality comparisons
Commit a1cbe4b5 added a check for spaces around assignments and this
patch extends it to checks for spaces around '=='.  One exception is
virAssertCmpInt where comma after '==' is acceptable (since it is a
macro and '==' is its argument).

dff93f8cab Add API for calling systemd-machined's DBus API
To register virtual machines and containers with systemd-machined,
and thus have cgroups auto-created, we need to talk over DBus.
This is somewhat tedious code, so introduce a dedicated function
to isolate the DBus call in one place.

711ca22a20 syntax-check: ignore all quoted strings in bracket-spacing
Ignore strings with an escaped double quote too.

This removes the need for special handling of quotes in the
semicolon check.

ba0880b25c syntax-check: Add the rule to forbid whitespace before ";"
Only a few cases are allowed:

1) The expression is empty for "for" loop, E.g.

  for (i = 0; ; i++)

2) An empty statement

  while (write(statuswrite, &status, 1) == -1 &&
         errno == EINTR)
      ; /* empty */

3) ";" is inside double-quote, I.e, as part of const string. E.g.

  vshPrint(ctl, "a ; b ; cd;\n");

The "for" loop in src/rpc/virnettlscontext.c is the special case,
1) applies for it, so change it together in this patch.

a3e95abeb5 Document bracket whitespace rules & add syntax-check rule
This documents the following whitespace rules

      if(foo)   // Bad
      if (foo)  // Good

      int foo (int wizz)  // Bad
      int foo(int wizz)   // Good

      bar = foo (wizz);  // Bad
      bar = foo(wizz);   // Good

      typedef int (*foo) (int wizz);  // Bad
      typedef int (*foo)(int wizz);   // Good

      int foo( int wizz );  // Bad
      int foo(int wizz);    // Good

There is a syntax-check rule extension to validate all these rules.
Checking for 'function (...args...)' is quite difficult since it
needs to ignore valid usage with keywords like 'if (...test...)'
and while/for/switch. It must also ignore source comments and
quoted strings.

It is not possible todo this with a simple regex in the normal
syntax-check style. So a short Perl script is created instead
to analyse the source. In practice this works well enough. The
only thing it can't cope with is multi-line quoted strings of
the form

 "start of string\
more lines\
more line\
the end"

but this can and should be written as

 "start of string"
 "more lines"
 "more line"
 "the end"

with this simple change, the bracket checking script does not
have any false positives across libvirt source, provided it
is only run against .c files. It is not practical to run it
against .h files, since those use whitespace extensively to
get alignment (though this is somewhat inconsistent and could
arguably be fixed).

The only limitation is that it cannot detect a violation where
the first arg starts with a '*', eg

   foo(*wizz);

since this generates too many false positives on function
typedefs which can't be supressed efficiently.
