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).

The test case average timing code has not been used by any test
case ever. Delete it to remove complexity.

0b30d3458a Avoid crash on OOM in virbuftest
The virbuftest code did not check virBufferError before
accessing the buffer contents, resulting in a crash on
OOM conditions.

dc6f2dadac Introduce OOM reporting to virAsprintf
Actually, I'm turning this function into a macro as filename,
function name and line number needs to be passed. The new
function virAsprintfInternal is introduced with the extended set
of arguments.

d0d0413e48 util: switch virBufferTrim to void
We don't care whether the trim was succesful or not anywhere
except the tests.

Switch it to void and set the buffer error on wrong usage.

7c9a2d88cd virutil: Move string related functions to virstring.c
The source code base needs to be adapted as well. Some files
include virutil.h just for the string related functions (here,
the include is substituted to match the new file), some include
virutil.h without any need (here, the include is removed), and
some require both.

9202f2c220 buf: support peeking at string contents
Right now, the only way to get at the contents of a virBuffer is
to destroy it.  But there are cases in my upcoming patches where
peeking at the contents makes life easier.  I suppose this does
open up the potential for bad code to dereference a stale pointer,
by disregarding the docs that the return value is invalid on the
next virBuf operation, but such is life.

* src/util/buf.h (virBufferCurrentContent): New declaration.
* src/util/buf.c (virBufferCurrentContent): Implement it.
* src/libvirt_private.syms (buf.h): Export it.
* tests/virbuftest.c (testBufAutoIndent): Test it.

cdb87b1c4b virBuffer: add way to trim back extra text
I'm tired of writing:

bool sep = false;
while (...) {
    if (sep)
       virBufferAddChar(buf, ',');
    sep = true;
    virBufferAdd(buf, str);
}

This makes it easier, allowing one to write:

while (...)
    virBufferAsprintf(buf, "%s,", str);
virBufferTrim(buf, ",", -1);

to trim any remaining comma.

* src/util/buf.h (virBufferTrim): Declare.
* src/util/buf.c (virBufferTrim): New function.
* tests/virbuftest.c (testBufTrim): Test it.

9943276fd2 Cleanup for a return statement in source files
Return statements with parameter enclosed in parentheses were modified
and parentheses were removed. The whole change was scripted, here is how:

List of files was obtained using this command:
git grep -l -e '\<return\s*([^()]*\(([^()]*)[^()]*\)*)\s*;' |             \
grep -e '\.[ch]$' -e '\.py$'

Found files were modified with this command:
sed -i -e                                                                 \
's_^\(.*\<return\)\s*(\(\([^()]*([^()]*)[^()]*\)*\))\s*\(;.*$\)_\1 \2\4_' \
-e 's_^\(.*\<return\)\s*(\([^()]*\))\s*\(;.*$\)_\1 \2\3_'

Then checked for nonsense.

The whole command looks like this:
git grep -l -e '\<return\s*([^()]*\(([^()]*)[^()]*\)*)\s*;' |             \
grep -e '\.[ch]$' -e '\.py$' | xargs sed -i -e                            \
's_^\(.*\<return\)\s*(\(\([^()]*([^()]*)[^()]*\)*\))\s*\(;.*$\)_\1 \2\4_' \
-e 's_^\(.*\<return\)\s*(\([^()]*\))\s*\(;.*$\)_\1 \2\3_'

fd9c052e6d virbuf: add auto-indentation support
Rather than having to adjust all callers in a chain to deal with
indentation, it is nicer to have virBuffer do auto-indentation.

* src/util/buf.h (_virBuffer): Increase size.
(virBufferAdjustIndent, virBufferGetIndent): New prototypes.
* src/libvirt_private.syms (buf.h): Export new functions.
* src/util/buf.c (virBufferAdjustIndent, virBufferGetIndent): New
functions.
(virBufferSetError, virBufferAdd, virBufferAddChar)
(virBufferVasprintf, virBufferStrcat, virBufferURIEncodeString):
Implement auto-indentation.
* tests/virbuftest.c (testBufAutoIndent): Test it.
(testBufInfiniteLoop): Don't rely on internals.
Idea by Daniel P. Berrange.

68ea80cfdd maint: rename virBufferVSprintf to virBufferAsprintf
We already have virAsprintf, so picking a similar name helps for
seeing a similar purpose.  Furthermore, the prefix V before printf
generally implies 'va_list', even though this variant was '...', and
the old name got in the way of adding a new va_list version.

global rename performed with:

$ git grep -l virBufferVSprintf \
  | xargs -L1 sed -i 's/virBufferVSprintf/virBufferAsprintf/g'

then revert the changes in ChangeLog-old.

20986e58aa tests: simplify common setup
A few of the tests were missing basic sanity checks, while most
of them were doing copy-and-paste initialization (in fact, some
of them pasted the argc > 1 check more than once!).  It's much
nicer to do things in one common place, and minimizes the size of
the next patch that fixes getcwd usage.

18af6f4e64 buf: Fix possible infinite loop in EscapeString, VSnprintf
The current code will go into an infinite loop if the printf generated
string is >= 1000, AND exactly 1 character smaller than the amount of free
space in the buffer. When this happens, we are dropped into the loop body,
but nothing will actually change, because count == (buf->size - buf->use - 1),
and virBufferGrow returns unchanged if count < (buf->size - buf->use)

Fix this by removing the '- 1' bit from 'size'. The *nprintf functions handle
the NULL byte for us anyways, so we shouldn't need to manually accommodate
for it.

Here's a bug where we are actually hitting this issue:
https://bugzilla.redhat.com/show_bug.cgi?id=602772

v2: Eric's improvements: while -> if (), remove extra va_list variable,
    make sure we report buffer error if snprintf fails

v3: Add tests/virbuftest which reproduces the infinite loop before this
    patch, works correctly after
