Delphi Clipboard History
[WayBack] Castalia had a Clipboard History for Delphi since a long time and since the acquisition of it around Delphi XE8, that was [Archive.is] integrated into the IDE for everyone to use as the [WayBack] “Delphi Clipboard History”
Some people object to the history viewer, for instance:
Even though used by a lot of password managers to transfer saved passwords to applications requiring credentials, the clipboard isn’t really a secure place as it is a shared resource that any application can monitor: [WayBack] Is a password in the clipboard vulnerable to attacks? – Information Security Stack Exchange.
It’s just that often the clipboard is about the only way to communicate date between two applications.
The real reason to get rid of the clipboard history is that in many Delphi versions it causes trouble with RichEdit controls: [Archive.is] Castalia’s Clipboard history + TRichEdit = IDE deadlock | Andy’s Blog and Tools after Eugene Kotlyarov posted a [WayBack] bug issue on G+.
I’m still not sure why Castalia and Delphi include a Clipboard History and even show it by default as:
If you would want to build such a tool (that can hide itself when not needed), then use the free repository at chrisrolliston/CCR.Clipboard: Extended TClipboard implementation for Delphi (FMX and VCL) [Archive.is] Ditto download | SourceForge.net

Before upgrading a Tumbleweed system, it makes sense to check which is your local and which is the on-line version. This is actually a tad more complicated than it sounds.
There are three versions involved:
aarch64 used on https://download.opensuse.org/ports/aarch64/tumbleweed/repo/oss/repodata/ file *-primary.xml.gz and http://download.opensuse.org/ports/aarch64/tumbleweed/repo/oss/aarch64/ in files openSUSE-release-*-1.1.aarch64.rpmThere is a mismatch between the last two as a side effect of decoupling the arm port a bit from the high checkin frequency of openSUSE:Factory; ARM simply has not enough power to build the snapshot in the same time Intel and PowerPC can do.
[WayBack] Dominique a.k.a. DimStar (Dim*) – A passionate openSUSE user thinks the last two are mismatched is a side effect off [WayBack] osc service remoterun operates on outdated sources (product builder) · Issue #4768 · openSUSE/open-build-service · GitHub.
He also tech-reviewed this post.
There are various ways to get your local version:
The easiest is to inspect the file /etc/os-release, for instance 20180208 in the file content:
NAME="openSUSE Tumbleweed" # VERSION="20180208 " ID=opensuse ID_LIKE="suse" VERSION_ID="20180208" PRETTY_NAME="openSUSE Tumbleweed" ANSI_COLOR="0;32" CPE_NAME="cpe:/o:opensuse:tumbleweed:20180208" BUG_REPORT_URL="https://bugs.opensuse.org" HOME_URL="https://www.opensuse.org/"
You can also perform rpm --query --provides openSUSE-release | grep "product(openSUSE)" which for the same install returned this product(openSUSE) = 20180208-0.
Finally, you can use zypper to query the installed product which also includes the version:
$ zypper search --installed-only --type product --details Loading repository data... Reading installed packages... S | Name | Type | Version | Arch | Repository ---+----------+---------+------------+---------+------------------ i+ | openSUSE | product | 20180228-0 | aarch64 | (System Packages)
I will explain this for the aarch64 architecture, but the mechanism holds for all architectures, it is just that the directory names vary.
Architectures and base directories you can use this mechanism with:
i586, i686 and x86_64
aarch64
armv6hl
armv7hl
ppc, ppc64 and ppc64le
s390x
Each architecture contains the version number in two kinds of places:
*-primary.xml.gz referenced from repomd.xml in the repodata subdirectory?P=openSUSE-release-2*Back to the aarch64 architecture:
Getting the version through repomd.xml is what zypper does based on a slight adoption of https://en.opensuse.org/openSUSE:Standards_Rpm_Metadata#Repository_layout resulting in release version 20180324:
Inspect https://download.opensuse.org/ports/aarch64/tumbleweed/repo/oss/repodata/repomd.xml for the name of *-primary.xml.gz (in this case https://download.opensuse.org/ports/aarch64/tumbleweed/repo/oss/repodata/d701c298b21d0b995c9560f9cfcc84685cb916deacc4f4c4a613a9b9d8f5aa57-primary.xml.gz
Download that .gz file and uncompress it
Inspect the *-primary.xml from it, look inside the metatadata root element for a package having a name element with value openSUSE-release: that packageelement now has a version element having a ver attribute containing the release version text.
Example file content:
<?xml version="1.0" encoding="UTF-8"?>
<metadata xmlns="http://linux.duke.edu/metadata/common" xmlns:rpm="http://linux.duke.edu/metadata/rpm" packages="35006">
<!-- ... -->
<package type="rpm">
<name>openSUSE-release</name>
<arch>aarch64</arch>
<version epoch="0" ver="20180324" rel="1.1"/>
<!-- ... -->
</package>
<!-- ... -->
</metadata>Getting the version through the name of the openSUSE-release-2* package:
openSUSE-release-20180324-1.1.aarch64.rpm indicating release version 20180324I will explain this for the aarch64 architecture, but the mechanism holds for all architectures that build on openQA, it is just that the directory names vary and not all architectures are running on openQA.
Architectures and base directories you can use this mechanism with:
i586, i686 and x86_64 (let’s call this platform Intel)
x86_64 and some i586)x86_64)aarch64 (let’s call this platform ARM)
ppc, ppc64 and ppc64le (let’s call this platform PowerPC)
ppc64 and ppc64le)s390x (let’s call this platform System Z)
Architectures not on openQA:
armv6hlarmv7hlEach platform contains the version number in two kinds of places:
media.1/media and media.1/productsBack to the aarch64 architecture on the ARM platform:
https://download.opensuse.org/ports/aarch64/tumbleweed/repo/oss/media.1/media
openSUSE - openSUSE-20180322-aarch64-Build46.1-Media

For a very long time I’ve discouraged people from using non-ASCII characters in identifiers. It still holds.
In the past, transliterations messed things up. Even with increased support for Unicode, tools still screw non-ASCII characters up.
Delphi is not alone in this (the most important one is the DFM view as text support), see this report: [RSP-16767] Viewing a form as text fails with non ascii control or event names – Embarcadero Technologies (you need an account for this, but the report is visible for anyone):
Viewing a form as text fails with non ascii control or event names Comment
Steps:
- create a new VCL forms application
- drop a label onto the form
- change the name of that label to lblÜberfall (note the U-umlaut)
- switch to view as text
- exp: DFM content shown as text
- act: first line is shown incorrectly (see screenhsot)
