FBINTF Change Log version (1.1-4 Build 11291) Fri, 28 Dec 2018 10:04:19 +0000
|
| 2 |
|
| 3 |
1. Fix a problem with the SQL parameter parser that failed to recognise parameters
|
| 4 |
where the second character of the parameter name is a numeric.
|
| 5 |
|
| 6 |
2. New method for IAttachment: procedure getFBVersion(version: TStrings);
|
| 7 |
This returns the isc_version connection information as one or more lines.
|
| 8 |
This is the same information as returned by isql with the -z option.

FBINTF Change Log version (1.1-3) Wed, 05 Dec 2018 14:28:10 +0000
|
| 12 |
|
| 13 |
1. DARWIN only syntax error: fix missing semi-colon in TFBClientAPI.LoadIBLibrary
|
| 14 |
|
| 15 |
2. Restrict IsMultiThread check to Unix only for compatibility with
|
| 16 |
https://bugs.freepascal.org/view.php?id=30535
|
| 17 |
|
| 18 |
3. New SQL Tokeniser added to IBUtils. This is used to pre-process SQL with
|
| 19 |
named parameters and is intended to avoid problems with (e.g.) Execute Block
|
| 20 |
and processing internal parameters as statement parameters.
|
| 21 |
|
| 22 |
4. New interface IFirebirdLibrary provides access to the underlying firebird DLL
|
| 23 |
or shared object. Available via a new member (GetFBLibrary) of IFirebirdAPI.
|
| 24 |
|
| 25 |
5. New function added to IB.pas
|
| 26 |
|
| 27 |
function LoadFBLibrary(aLibPathName: string): IFirebirdLibrary
|
| 28 |
|
| 29 |
This allows a Firebird Library to be loaded from an explicit path. use the
|
| 30 |
IFirebirdLibrary.GetFirebirdAPI member function to get the Firebird API using
|
| 31 |
the library. It is possible to load Firebird libraries from different locations
|
| 32 |
simultaneously, each with a distinct IFirebirdAPI.
|
| 33 |
|
| 34 |
FBINTF Change Log version (1.1-2) Mon, 16 Apr 2018 09:30:32 +0100
|
| 35 |
|
| 36 |
1. Firebird.pas: {$OBJECTCHECKS OFF} added to file to avoid runtime error when
|
| 37 |
program compiled with -CR command line switch.
|
| 38 |
|
| 39 |
2. IServiceManager additions (informational):
|
| 40 |
function getProtocol: TProtocol;
|
| 41 |
function getPortNo: AnsiString;
|
| 42 |
|
| 43 |
3. IServiceManager improved error handling. Interfaces changed:
|
| 44 |
function Start(Request: ISRB; RaiseExceptionOnError: boolean=true): boolean;
|
| 45 |
function Query(SQPB: ISQPB; Request: ISRB; RaiseExceptionOnError: boolean=true) :IServiceQueryResults; overload;
|
| 46 |
function Query(Request: ISRB; RaiseExceptionOnError: boolean=true) :IServiceQueryResults; overload;
|
| 47 |
|
| 48 |
4. IAttachment addition (informational)
|
| 49 |
function GetSecurityDatabase: AnsiString;
|
| 50 |
|
| 51 |
5. IStatement: performance counters now updated after each Fetch. GetPerfStatistics
|
| 52 |
thus now returns accumulated stats for a select statement from opening a cursor
|
| 53 |
up to the last fetch.
|
| 54 |
|
| 55 |
6. DARWIN: uloadlibrary.inc bug fix. Many thanks to Luigi Naimi for correcting
|
| 56 |
the problem.
|
| 57 |
|
| 58 |
7. Type change: "TPerfCounters = array[TPerfStats] of Int64". Note "Int64"
|
| 59 |
replaces deprecated "comp" type.
|
| 60 |
|
| 61 |
10. Testsuite Test10 updated to include thread synchronisation for event reporting.
|
| 62 |
|
| 63 |
11. URL Connection Strings: inet4 and inet6 now recognised.
|
| 64 |
|
| 65 |
12. IBUtils: Parse and Make Connect String now recognise URL style loopback syntax.
|
| 66 |
|
| 67 |
13. IAttachment.CharSetName2CharSetID is now performed case insensitive.
|
| 68 |
|
| 69 |
|
| 70 |
FBINTF Change Log version (1.1-1) Tue, 27 Feb 2018 16:51:16 +0000
|
| 71 |
|
| 72 |
1. IBUtils.QuoteIdentifierIfNeeded: Add check for space character.
|
| 73 |
|
| 74 |
2. IAttachment: add two new methods
|
| 75 |
function HasDefaultCharSet: boolean;
|
| 76 |
function GetDefaultCharSetID: integer;
|
| 77 |
|
| 78 |
These return, respectively, true if a connection default character set was
|
| 79 |
specified and the character set id of the connection default character set.
|
| 80 |
The DefaultCharSetID is cached when the connection is opened and hence does not
|
| 81 |
require a database lookup.
|
| 82 |
|
| 83 |
3. Avoid exception when a text blob is a stored procedure parameter.
|
| 84 |
|
| 85 |
4. Update test suite to include a test for a stored proc returning a text blob.
|
| 86 |
|
| 87 |
5. IAttachment: add
|
| 88 |
function GetRemoteProtocol: AnsiString;
|
| 89 |
function GetODSMajorVersion: integer;
|
| 90 |
function GetODSMinorVersion: integer;
|
| 91 |
function GetAuthenticationMethod: AnsiString;
|
| 92 |
|
| 93 |
These results are cached when the connection is opened and hence do not
|
| 94 |
require a database lookup.
|
| 95 |
|
| 96 |
6. IAttachment: add "function GetConnectString: AnsiString;" This returns the
|
| 97 |
connect string used to create/connect to the database.
|
| 98 |
|
| 99 |
7. IAttachment: Create Database using SQL statement. The username and password
|
| 100 |
are now extracted and used to populate a DPB made available via IAttachment.getDPB.
|
| 101 |
It is now possible to use IAttachment disconnect/connect to reconnect to
|
| 102 |
a database for which the initial connection was established by a create
|
| 103 |
database sql statement. Available in FPC only.
|
| 104 |
|
| 105 |
8. Update Test 1 to test 5, 6 and 7 above.
|
| 106 |
|
| 107 |
9. IBUtils code tidy up.
|
| 108 |
|
| 109 |
10. Parameter Block interfaces "find" method. As documented, this should have
|
| 110 |
returned a nil interface when the item could not be found. Instead, an empty
|
| 111 |
interface item was returned. "Find" now works as documented and will return
|
| 112 |
a nil interface if the item cannot be found.
|
| 113 |
|
| 114 |
11. DBInformation: support added for isc_info_active_tran_count and isc_info_creation_date.
|
| 115 |
|
| 116 |
12. DBInformation: New interfaces: IDIRB and IDIRBItem added to support DB Information
|
| 117 |
requests with additional parameters. This is to enable support for fb_info_page_contents
|
| 118 |
(return of page contents). Response to fb_info_page_contents returned as
|
| 119 |
a string with code page CP_NONE.
|
| 120 |
|
| 121 |
13. DBInformation: Support for fb_info_pages_used and fb_info_pages_free added, plus
|
| 122 |
test suite updated.
|
| 123 |
|
| 124 |
14. DBInformation: Support for fb_info_crypt_key (Firebird 3.0.3 onwards) added as
|
| 125 |
a string type, and fb_info_conn_flags (Firebird 3.0.3 onwards) added as an integer type.
|
| 126 |
|
| 127 |
15. Service Manager: List of protocols supported expanded to include inet, wnet and xnet.
|
| 128 |
An overloaded version of IIFirebirdAPI.GetServiceManager also allows a non
|
| 129 |
default connection port to be specified.
|
| 130 |
|
| 131 |
FBINTF Change Log version (1.1-0) Sun, 07 Jan 2018 15:20:02 +0000
|
| 132 |
|
| 133 |
1. Fix issues with setting SQL Param values using SetAsString with Numeric types.
|
| 134 |
Scale is no longer ignored.
|
| 135 |
|
| 136 |
2. Fix issues with setting SQL Param values using SetAsString with Date values
|
| 137 |
not in locale format but which are recognised by Firebird. Date values that
|
| 138 |
cannot be converted to a string using Pascal library are now passed through
|
| 139 |
to Firebird as Text Strings.
|
| 140 |
|
| 141 |
3. Lookup character set name by codepage amended to ensure that CP_UTF8 returns
|
| 142 |
UTF8 and not UNICODE_FSS.
|
| 143 |
|
| 144 |
4. Charset ID problem. When using Firebird 3, with no default database character set
|
| 145 |
and a column has a non-default collation specified, an incorrect character set
|
| 146 |
id was being reported that could result in a 'division by zero' error when
|
| 147 |
used by IBX. This has now been fixed.
|
| 148 |
|
| 149 |
5. Move GetCharsetName, CharSetID2CodePage, CodePage2CharSetID, CharSetName2CharSetID,
|
| 150 |
CharSetWidth from IFirebirdAPI to IAttachment. This is a better data model as
|
| 151 |
the character sets supported can be updated on a per database basis. That is
|
| 152 |
it is possible to add a (Firebird) user defined character set to a database.
|
| 153 |
|
| 154 |
6. Add RegisterCharSet to IAttachment. This is used to register a user defined character
|
| 155 |
set supported by Firebird with the API.
|
| 156 |
|
| 157 |
7. Add missing isc_info_db_read_only to list of decoded Database Information items
|
| 158 |
in FBOutputBlock.pas and update test suite to include this item.
|
| 159 |
|
| 160 |
8. FB30Client: avoid always using "StartMultiple" when only a single database attachment.
|
| 161 |
|
| 162 |
9. Loading Windows fbclient.dll: when using the FIREBIRD variable to locate the client
|
| 163 |
library or finding it by disk location, the PATH environment variable is now also set to
|
| 164 |
include the FIREBIRD directory. This is to ensure that the correct dlls in the
|
| 165 |
firebird client library dependencies are loaded.
|
| 166 |
|
| 167 |
10. Testsuite: Ensure consistent UTF-8 output on Windows console.
|
| 168 |
|
| 169 |
11. Testsuite: Update Windows script to include FPC 3.0.4 in search path.
|
| 170 |
|
| 171 |
12. FB30Statement: Protect call to "Move" and avoid calling with a nil pointer
|
| 172 |
|
| 173 |
13. FB30Statement: A check has been added to ensure that all SQL Parameters
|
| 174 |
have been given a value (including NULL). Previously, failing to set the
|
| 175 |
value of an SQL Parameter could give rise to unpredictable results or
|
| 176 |
an SQLDA error.
|
| 177 |
|
| 178 |
14. FB30Statement/FB25Statement: Set SQLParam "modified" when string value set.
|
| 179 |
|
| 180 |
15. FBAttachment: Avoid string reference count error when processing an Ansistring
|
| 181 |
parameter in an array of const passed to IAttachment.OpenCursor, etc.
|
| 182 |
|
| 183 |
16. FBAttachment: Allow for WideString and UnicodeString parameters in an array
|
| 184 |
of const passed to IAttachment.OpenCursor, etc.
|
| 185 |
|
| 186 |
|
| 187 |
FBINTF Change Log version (1.0-2) Sat, 04 Mar 2017 14:43:56 +0000
|
| 188 |
|
| 189 |
1. Change syntax to Mode Delphi
|
| 190 |
|
| 191 |
2. Change all uses of string type to explicit AnsiString in order to ensure
|
| 192 |
compatibility between Delphi and FPC.
|
| 193 |
|
| 194 |
3. Various syntax changes to ensure Delphi and FPC compilation including GUIDs
|
| 195 |
defined for each interface.
|
| 196 |
|
| 197 |
4. Generics syntax variations for Delphi added
|
| 198 |
|
| 199 |
5. PChar replaced with PByte expect where an actual string is being referenced,
|
| 200 |
where PAnsiChar is used instead.
|
| 201 |
|
| 202 |
6. Review of type definitions in IBExternals to ensure Delphi compatibility
|
| 203 |
|
| 204 |
7. Testsuite updated for Delphi
|
| 205 |
|
| 206 |
FBINTF Change Log version (1.0-1) Fri, 24 Feb 2017 12:17:57 +0000
|
| 207 |
|
| 208 |
1. Limit maximum Blob segment read/write to MaxuShort. Avoids data loss with
|
| 209 |
large blobs and the FB3 API.
|
| 210 |
|
| 211 |
2. Update Event Handling algorithm to avoid looping due to recreation of the
|
| 212 |
event block.
|
| 213 |
|
| 214 |
3. Avoid invalid XSQLDA error when the only parameter is updated to null
|
| 215 |
|
| 216 |
4. Array Handling: fix problem with text arrays with character set none. When the
|
| 217 |
DB connection has a default character set (e.g. UTF8), an error is raised by
|
| 218 |
Firebird if the space allocated is not enough to allow for transliteration, even
|
| 219 |
though it is not required for character set none.
|
| 220 |
|
| 221 |
5. IBUtils: List of reserved words brought up-to-date
|
| 222 |
|
| 223 |
6. Add ISQL style performance statistics collection to IStatement
|
| 224 |
|
| 225 |
7. Add IFirebirdAPI.CreateDatabase variant to allow execution of user provided
|
| 226 |
CREATE DATABASE statement.
|
| 227 |
|
| 228 |
8. Update SQL Statement parsing to allow for Array Dimensions. That is so that the ':' in
|
| 229 |
an array dimension is not mistaken for a named parameter prefix.
|
| 230 |
|
| 231 |
9. Trim function no longer applied to result of GetAsString for SQL_TEXT
|
| 232 |
when Character set is octets. Avoids loss of non printable characters at start of string.
|
| 233 |
|
| 234 |
10. Add function GetPerfStatistics to IStatement. This returns ISQL like performance
|
| 235 |
statistics for the last action. Requires use of procedure IStatement.EnableStatistics
|
| 236 |
to enable stats gathering.
|
| 237 |
|
| 238 |
11. API Version information added as constants to IB.pas
|
| 239 |
|
| 240 |
12. BlobMetaData character set id should now be the same as that given by IColumnMetaData.GetCharSetID
|
| 241 |
|
| 242 |
13. Firebird Character set "NONE" now interpreted as codepage CP_ACP.
|
| 243 |
|
| 244 |
