6d660250cc D-Bus server: remove redundant m_server
The base class already has a copy of it, so Session doesn't
need its own. Found by cppcheck 1.65.

fdd66536ce PIM: fix cppcheck control flow warning
The "func" variable was correctly initialized to NULL if no comparsion
matches, but cppcheck 1.65 warns anyway. Use the more readable
intialization to NULL in the final else clause.

6977a261e3 PIM: fix invalid call to folks_note_field_details_new
folks_note_field_details_new() takes an additional uid parameter.
Passing NULL is okay, but SyncEvolution wasn't doing that due to
an incorrect function type cast. Found by valgrind only after
a valgrind and tool chain update. Probably we passed a valid
value accidentally before.

Fixed by using a wrapper function.

Ideally the function typecast should get replaced entirely with just casting
the returned pointer.

f3f689b857 PIM: fix phone number normalization
The parsed number always has a country code, whereas SyncEvolution expected it
to be zero for strings without an explicit country code. This caused a caller
ID lookup of numbers like "089788899" in DE to find only telephone numbers in
the current default country, instead of being more permissive and also finding
"+189788899". The corresponding unit test was broken and checked for the wrong
result. Found while investigating an unrelated test failure when updating
libphonenumber.

EDS handles this differently, by calling ParseAndKeepRawInput() if necessary
(checked by configure) and looking at the source of the country code. Instead
of replicating that logic, let's use EPhoneNumber. This means that EDS has to
be compiled with libphonenumber support, because SyncEvolution can no longer
fall back to using libphonenumber directly.

For testing purposes it is still useful to not depend on X-EVOLUTION-E164.
testLocaledPhone uses this at the moment, because re-generating
X-EVOLUTION-E164 during a locale change seems to be broken at the moment
in the intel-work-3-12 branch.

The test itself has to be updated for the newer libphonenumber (6.1.1 instead
of 5.3.2). The "12345" string it relied upon now gets parsed consistently in
US and DE. Instead we use the "01164 3 331 6005" string (as in libphonenumber
tests) which is treated differently.

944281a024 PIM: fix libphonenumer patch
The "Fixed compilation error when using libphonenumber from revision
>= 568" patch caused a double free error because SetLogger() owns the
logger instance and, with libphonenumber >= r571 actually frees the
instance.

Old libphonenumber release are compatible with the revised call,
however, they never free the instance.

d8c8e153ea PBAP: avoid empty field filter
Empty field filter is supposed to mean "return all supported
fields". This used to work and stopped working with Android phones
after an update to 4.3 (seen on Galaxy S3); now the phone only
returns the mandatory TEL, FN, N fields.

The workaround is to replace the empty filter list with the list of
known and supported properties. This means we only pull data we really
need, but it also means we won't get to see any additional properties
that the phone might support.

42daad6034 signon: make Accounts optional
The new "signon" provider only depends on lib[g]signon-glib. It uses
gSSO if found, else UOA. Instead of pulling parameters and the
identity via libaccounts-glib, the user of SyncEvolution now has to
ensure that the identity exists and pass all relevant parameters
in the "signon:" username.

This does not have to be user-friendly, so the machine-readable
GVariant text dump format is used to pass all parameters.

026903b57d gSSO: adapt to gSSO >= 2.0
gSSO >= 2.0 requires a list of realms to which the identity
applies. We take this list from a new "Realms" setting for the
provider in Accounts.

This is how SyncEvolution does it; it hasn't been checked what
upstream will do around this. In Tizen, libaccounts is not used
and thus a different solution is needed there.

The API of libgsignond >= 2.0 was also changed to be more compatible
with the original libsignon. This allows (and requires) removing
some gSSO ifdefs.

47940a959d WebDAV: fix database scan on iCloud
The calendar home set URL on iCloud (the one ending in /calendars/) is
declared as containing calendar data. That was enough for
SyncEvolution to accept it incorrectly as calendar. However, the home
set only contains calendar data indirectly.

We must use the stricter check for leaf collections containing the
right data.

f5f88c61aa WebDAV: support redirects between hosts and DNS SRV lookup based on URL
When finding a new URL, we must be prepared to reinitialize the Neon
session with the new host settings. To implement this, candidates are
now full URIs, not just paths on the initial host.

A home set on iCloud contains full URLs, not just paths. We need to
parse the individual entries, which happens to work for paths and URLs
because paths are just special URLS without an explicit host.

iCloud does not have .well-known support on its www.icloud.com
server. To support lookup with a non-icloudd.com email address, we
must do DNS SRV lookup when access to .well-known URLs fails. We do
this without a www prefix on the host first, because that is what happens
to work for icloud.com.

With these changes it becomes possible to do database scans on Apple
iCloud, using syncURL=https://www.icloud.com or
syncURL=https://icloud.com. The former is a bit faster because the
icloud.com redirects to www.icloud.com before we end up doing the DNS
SRV lookup to find the CalDAV resp. CardDAV hosts.

8df1ec15af WebDAV: don't retry after 501 error

1910e5efb3 WebDAV: send "User-Agent: SyncEvolution"

is more certain whether and for what it is needed.

0f136e2884 WebDAV: refactor and fix DNS SRV lookup
Moved into a separate function and fixed return code handling: due to
missing decoding of the shell scripts return code, all errors were

ae84edf417 testing: simulate remote item manipulation
Traditionally, SyncEvolution only modified remote data via syncing.
This is not enough because it does not cover data on the remote side
that SyncEvolution cannot sync.

The new tests solve this by using the command line's import/update
operations which modify data more or less directly.

Now we can test:
- downloading data created remotely
- uploading data via sync, export directly, compare
- simulate conflicts with changes made remotely

The download and upload test include full round-trips, i.e.
the initial transfer plus a change that needs to be synced back.

Because this is highly dependent on the exact data stored by the
peer, all these tests depend on per-peer test data and scripts
for modifying that data. The tests only get enabled if the test
data is found.

The initial test data covers Apple Calendar server, EDS<->EDS
and Google Contacts.

9c0916bee8 vcard profile: avoid data loss during merging
When resolving a merge conflict, repeating properties were taken
wholesale from the winning side (for example, all email addresses). If
a new email address had been added on the loosing side, it got lost.

Arguably it is better to preserve as much data as possible during a
conflict. SyncEvolution now does that in a merge script by checking
which properties in the loosing side do not exist in the winning side
and copying those entries.

Typically only the main value (email address, phone number) is checked
and not the additional meta data (like the type). Otherwise minor
differences (for example, both sides have same email address, but with
different types) would lead to duplicates.

Only addresses are treated differently: for them all attributes
(street, country, city, etc.) are compared, because there is no single
main value.

When copying properties which may have labels, the new entries must be
added such that a unique label can be copied or set. Other properties
can be added at the end of their array.

8c12816dec vcard profile: avoid X-ABLabel without a real property value
The modern profile typically doesn't generate empty properties, and therefore
it is useless to create an IMPP, X-ABRELATEDNAMES or X-ABDATE entry with has
an empty value. It just has the effect of creating X-ABLabels which are not
attached to any property.

933d10f97c CardDAV: use Apple/Google/CardDAV vCard flavor
In principle, CardDAV servers support arbitrary vCard 3.0
data. Extensions can be different and need to be preserved. However,
when multiple different clients or the server's Web UI interpret the
vCards, they need to agree on the semantic of these vCard extensions.

In practice, CardDAV was pushed by Apple and Apple clients are
probably the most common clients of CardDAV services. When the Google
Contacts Web UI creates or edits a contact, Google CardDAV will
send that data using the vCard flavor used by Apple.

Therefore it makes sense to exchange contacts with *all* CardDAV
servers using that format. This format could be made configurable in
SyncEvolution on a case-by-case basis; at the moment, it is
hard-coded.

During syncing, SyncEvolution takes care to translate between the
vCard flavor used internally (based on Evolution) and the CardDAV
vCard flavor. This mapping includes:

X-AIM/JABBER/... <-> IMPP + X-SERVICE-TYPE

  Any IMPP property declared as X-SERVICE-TYPE=AIM will get
  mapped to X-AIM. Same for others. Some IMPP service types
  have no known X- property extension; they are stored in
  EDS as IMPP. X- property extensions without a known X-SERVICE-TYPE
  (for example, GaduGadu and Groupwise) are stored with
  X-SERVICE-TYPE values chosen by SyncEvolution so that
  Google CardDAV preserves them (GroupWise with mixed case
  got translated by Google into Groupwise, so the latter is used).

  Google always sends an X-ABLabel:Other for IMPP. This is ignored
  because the service type overrides it.

  The value itself also gets transformed during the mapping. IMPP uses
  an URI as value, with a chat protocol (like "aim" or "xmpp") and
  some protocol specific identifier. For each X- extension the
  protocol is determined by the property name and the value is the
  protocol specific identifier without URL encoding.

X-SPOUSE/MANAGER/ASSISTANT <-> X-ABRELATEDNAMES + X-ABLabel

  The mapping is based on the X-ABLabel property attached to
  the X-ABRELATEDNAMES property. This depends on the English
  words "Spouse", "Manager", "Assistant" that Google CardDAV
  and Apple devices seem to use regardless of the configured
  language.

  As with IMPP, only the subset of related names which have
  a corresponding X- property extension get mapped. The rest
  is stored in EDS using the X-ABRELATEDNAMES property.

X-ANNIVERSARY <-> X-ABDATE

  Same here, with X-ABLabel:Anniversary as the special case
  which gets mapped.

X-ABLabel parameter <-> property

  CardDAV vCards have labels attached to arbitrary other properties
  (TEL, ADR, X-ABDATE, X-ABRELATEDNAMES, ...) via vCard group tags:
  item1.X-ABDATE:2010-01-01
  item1.X-ABLabel:Anniversary

  The advantage is that property values can contain arbitrary
  characters, including line breaks and double quotation marks,
  which is not possible in property parameters.

  Neither EDS nor KDE (judging from the lack of responses on the
  KDE-PIM mailing list) support custom labels. SyncEvolution could
  have used grouping as it is done in CardDAV, but grouping is not
  used much (not at all?) by the UIs working with the vCards in EDS
  and KDE. It seemed easier to use a new X-ABLabel parameter.

  Characters which cannot be stored in a parameter get converted
  (double space to single space, line break to space, etc.) during
  syncing. In practice, these characters don't appear in X-ABLabel
  properties anyway because neither Apple nor Google UIs allow entering
  them for custom labels.

  The "Other" label is used by Google even in case where it adds no
  information. For example, all XMPP properties have an associated
  X-ABLabel=Other although the Web UI does not provide a means to edit
  or show such a label. Editing the text before the value in the UI
  changes the X-SERVICE-TYPE parameter value, not the X-ABLabel as for
  other fields.

  Therefore the "Other" label is ignored by removing it during syncing.

X-EVOLUTION-UI-SLOT (the parameter used in Evolution to determine the
order of properties in the UI) gets stored in CardDAV. The only exception
is Google CardDAV which got confused when an IMPP property had both
X-SERVICE-TYPE and X-EVOLUTION-UI-SLOT parameters set. For Google,
X-EVOLUTION-UI-SLOT is only sent on other properties and thus ordering
of chat information can get lost when syncing with Google.

CardDAV needs to use test data with the new CardDAV vCard flavor.
Most CardDAV servers can store EDS vCards and thus
Client::Source::*::testImport passed (with minor tweaks in
synccompare) when using the default eds_contact.vcf, but
Client::Sync::*::testItems fails when comparing synced data with test
cases when the synced data uses the native format and the test cases
are still the ones from EDS.

A libsynthesis with URLENCODE/DECODE() and sharedfield parameter for
<property> is needed.

d90c952b4c WebDAV: avoid redundant work
Different backend functions had to ensure that a connection

74b0da36b7 vcard profile: remove unused fields

cca89dbf87 WebDAV: use server's order when listing collections
When doing a recursive scan of the home set, preserve the order of
entries as reported by the server and check the first one first. The
server knows better which entries are more relevant for the user (and
thus should be the default) or may have some other relevant
order. Previously, SyncEvolution replaced that order with sorting by
URL, which led to a predictable, but rather meaningless order.

For example, Google lists the users own calendar first, followed by
the shared calendars sorted alphabetical by their name. Now
SyncEvolution picks the main calendar as default correctly when
scanning from https://www.google.com/calendar/dav/.

29c08781ef WebDAV: improved database search (Google, Zimbra)
Zimbra has a principal URL that also serves as home set. When using it
as start URL, SyncEvolution only looked the URL once, without listing
its content, and thus did not find the databases.

When following the Zimbra principal URL indirectly, SyncEvolution did
check all of the collections there recursively. Unfortunately that
also includes many mail folders, causing the scan to abort after
checking 1000 collections (an internal safe guard).

The solution for both includes tracking what to do with a URL. For the
initial URL, only meta data about the URL itself gets
checked. Recursive scanning is only done for the home set. If that
home set contains many collections, scanning is still slow and may run
into the internal safe guard limit. This cannot be avoided because the
CalDAV spec explicitly states that the home set may contain normal
collections which contain other collections, so a client has to do the
recursive scan.

When looking at a specific calendar, Google CalDAV does not report
what the current principal or the home set is and therefore
SyncEvolution stopped after finding just the initial calendar. Now it
detects the lack of meta information and adds all parents also as
candidates that need to be looked at. The downside of this is that it
doesn't know anything about which parents are relevant, so it ends up
checking https://www.google.com/calendar/ and
https://www.google.com/.

In both cases Basic Auth gets rejected with a temporary redirect to
the Google login page, which is something that SyncEvolution must
ignore immediately during scanning without applying the resend
workaround for "temporary rejection of valid credentials" that can
happen for valid Google CalDAV URLs.

The sorting of sub collections is redundant and can be removed,
because sorting already happens when storing the information for each
path. When scanning Google CalDAV starting at
https://www.google.com/calendar/dav/, the main calendar gets listed by
Google first, but because we reorder by sorting by path, it ends up
last in the SyncEvolution database list and thus is not picked as
default. This needs to be fixed separately by preserving the server's
order.

c33205a7be WebDAV: use vCard UID handling in engine
This takes advantage of the engine setting (new items) and preserving
(existing items) the UID for backends and then generating it as part of
serialization.

The older hacks in create/setResourceName() relied on resource name matching
the UID, which is not guaranteed for items created by us via POST (depending
on the server) and/or other CardDAV clients.

The hacks could be removed; they are simply not used anymore at the moment.

4b2b2bb64e engine: UID support in contact data
Before, the UID property in a vCard was ignored by the engine.
Backends were responsible for ensuring that the property is
set if required by the underlying storage.

This change moves this into the engine:
- UID is now field. It does not get used for matching
  because the engine cannot rely on it being stored
  by both sides.
- It gets parsed if present, but only generated if
  explicitly enabled (because that is the traditional
  behavior).
- It is never shown in the DevInf's CtCap
  because the Synthesis engine would always show it
  regardless whether a rule enabled the property.
  That's because rules normally only get triggered
  after exchanging DevInf and thus DevInf has to
  be rule-independent. We don't want it shown because
  then merging the incoming item during a local sync
  would use the incoming UID, even if it is empty.
- Before writing, ensure that UID is set.

When updating an existing item, the Synthesis engine reads
the existing item, preserves the existing UID unless the peer
claims to support UID, and then updates with the existing UID.

This works for local sync (where SyncEvolution never claims
to support UID when talking to the other side). It will break
with peers which have UID in their CtCap although they
rewrite the UID and backends whose underlying storage cannot
handle UID changes during an update (for example, CardDAV).

A backend must still activate the UID property by setting m_backendRule
to LOCALSTORAGE-WITH-UID instead of the default LOCALSTORAGE.
Custom backend rules must include the new sub-rule HAVE-VCARD-UID.

See "[os-libsynthesis] UID + CardDAV" for a discussion of this change.
Long term it would be better to configure profiles without depending
on the rule hack.

82288638e0 WebDAV: handle read-only collections
Check whether a collection is read-only by reading ACL properties.
The check is intentionally a bit fuzzy to avoid accidentally marking
a collection as read-only.

All read-only collections are moved to the end of the found databases, to
avoid picking them as default when there are read/write collections. This
needs to be done in both "list all databases" mode (aka --print-databases)
and in "pick default database" mode (aka syncing with a source which
had no explicit 'database' set).

To use a read-only collection, configure it in the 'database'
property.

This is relevant for OwnDrive, aka ownCloud, which has a read-only "birthday"
calendar which was picked as default instead of the real calendar.

used in helper code does not. It is better to add the source name as
logging prefix. The other advantage is that all lines will have the
prefix, not just the first one.

The SyncSource operations need access to the SyncSource class which
contains them to access the display name of the SyncSource instance.
A positive a side effect of telling the wrappers about the instance at
construction time is that the caller no longer has to pass the source
reference.

This change allows removing the SyncSource::throwError() special
cases, which completes the transition towards having correct source
code location information for all exceptions.

c95bc08e61 logging: avoid empty " :" prefix
This could happen when using item operations on the command line.
In that case a source without name was created and that empty
name was inserted as prefix before errors encountered while
using the source.

Now empty string is the same as no string.

de8461f802 code restructing: Exception, throwError()
Raising exceptions via throwError() looses the original source code
location information. Fixing that by explicitly passing that
information as additional parameter, created with the preprocessor
macro SE_HERE.

Several files included the complex SyncContext.h only because needed
throwError(). A better place for the revised implementation is the
Exception class which used to be in util.h, now Exception.h.

Simplifying the include statements exposed indirect include
dependencies and removed "using namespace std" from the compilation of
some source files which happened to rely on it. We want to get rid of
that name space polution, so fix the code instead of adding it back.

7812dc126f DAV: enhanced database search
Additional databases where not found for several
reasons. SyncEvolution ignored all shared calendars
(http://calendarserver.org/ns/shared) and Google marks the additional
calendars that way. The other problem was that the check for leaf
collections (= collections which cannot contain other desired
collections) incorrectly excluded those collections instead of only
preventing listing of their content.

With this change,
https://www.google.com/calendar/dav/?SyncEvolution=Google can be used
as starting point for Google Calendar.

27af370ac2 WebDAV: do not mangle UID when sending items
The WebDAV backends contained a hack where the UID inside the data was forced
to be identical to the resource name. This is wrong for items created by us
via POST (because the server may choose a resource name != UID) or by some
other entity (where we have no idea how the resource name got chosen).

This commit removes the hack. Testing must be updated to pass correct data
with the same UID as on the server when updating an item, because the backend
will no longer ensure that and changing the UID of a resource gets rejected by
some servers.

The hack was introduced for peers which do not store the UID (for example, a
vCard or iCalendar 1.0 based SyncML client). A better solution must be found,
probably involving the Synthesis engine and its read/update/write cycle.

03a7b4f1ab DAV: more efficient item creation
PUT has the disadvantage that a client needs to choose a name and then
figure out what the real name on the server is. With Google CardDAV that
requires sending another request and only works because the server happens
to remember the original name (which is not guaranteed!).

POST works for new items without a name and happens to be implemented
by Google such that the response already includes all required
information (new name and revision string).

POST is checked for as described in RFC 5995 once before creating a new
item. Servers which don't support it continue to get a PUT.

The 403 status code must be checked to detect UID conflicts when adding
an item that already exists on the server.
