This was causing the 'pubkeys processed' + indicator on the 'Network Status' tab to not accurately reflect the + number of truly new addresses on the network. +- Use 32 threads for outgoing connections in order to connect quickly +- Fix typo when calling os.environ in the sys.platform=='darwin' case +- Allow the cancelling of a message which is in the process of being + sent by trashing it then restarting Bitmessage +- Bug fix: can't delete address from address book + +* Tue Apr 9 2013 Bob Mottram (4096 bits) - 0.2.8-1 +- Fixed Ubuntu & OS X issue: + Bitmessage wouldn't receive any objects from peers after restart. +- Inventory flush to disk when exiting program now vastly faster. +- Fixed address generation bug (kept Bitmessage from restarting). +- Improve deserialization of messages + before processing (a 'best practice'). +- Change to help Macs find OpenSSL the way Unix systems find it. +- Do not share or accept IPs which are in the private IP ranges. +- Added time-fuzzing + to the embedded time in pubkey and getpubkey messages. +- Added a knownNodes lock + to prevent an exception from sometimes occurring when saving + the data-structure to disk. +- Show unread messages in bold + and do not display new messages automatically. +- Support selecting multiple items + in the inbox, sent box, and address book. +- Use delete key to trash Inbox or Sent messages. +- Display richtext(HTML) messages + from senders in address book or subscriptions (although not + pseudo-mailing-lists; use new right-click option). +- Trim spaces + from the beginning and end of addresses when adding to + address book, subscriptions, and blacklist. +- Improved the display of the time for foreign language users. + +* Tue Apr 1 2013 Bob Mottram (4096 bits) - 0.2.7-1 +- Added debian packaging +- Script to generate debian packages +- SVG icon for Gnome shell, etc +- Source moved int src directory for debian standards compatibility +- Trailing carriage return on COPYING LICENSE and README.md diff --git a/slack.sh b/slack.sh new file mode 100755 index 00000000..cc71e1f3 --- /dev/null +++ b/slack.sh @@ -0,0 +1,48 @@ +#!/bin/bash + +APP=pybitmessage +PREV_VERSION=0.3.4 +VERSION=0.3.4 +RELEASE=1 +ARCH_TYPE=`uname -m` +BUILDDIR=~/slackbuild +CURRDIR=`pwd` +PROJECTDIR=${BUILDDIR}/${APP}-${VERSION}-${RELEASE} + +# Update version numbers automatically - so you don't have to +sed -i 's/VERSION='${PREV_VERSION}'/VERSION='${VERSION}'/g' Makefile debian.sh rpm.sh arch.sh puppy.sh ebuild.sh +sed -i 's/Version: '${PREV_VERSION}'/Version: '${VERSION}'/g' rpmpackage/${APP}.spec +sed -i 's/Release: '${RELEASE}'/Release: '${RELEASE}'/g' rpmpackage/${APP}.spec +sed -i 's/pkgrel='${RELEASE}'/pkgrel='${RELEASE}'/g' archpackage/PKGBUILD +sed -i 's/pkgver='${PREV_VERSION}'/pkgver='${VERSION}'/g' archpackage/PKGBUILD +sed -i "s/-${PREV_VERSION}-/-${VERSION}-/g" puppypackage/*.specs +sed -i "s/|${PREV_VERSION}|/|${VERSION}|/g" puppypackage/*.specs +sed -i 's/VERSION='${PREV_VERSION}'/VERSION='${VERSION}'/g' puppypackage/pinstall.sh puppypackage/puninstall.sh +sed -i 's/-'${PREV_VERSION}'.so/-'${VERSION}'.so/g' debian/*.links + + +# Make directories within which the project will be built +mkdir -p ${BUILDDIR} +mkdir -p ${PROJECTDIR} + +# Build the project +make clean +make +make install -B DESTDIR=${PROJECTDIR} + +# Copy the slack-desc and doinst.sh files into the build install directory +mkdir ${PROJECTDIR}/install +cp ${CURRDIR}/slackpackage/slack-desc ${PROJECTDIR}/install +cp ${CURRDIR}/slackpackage/doinst.sh ${PROJECTDIR}/install + +# Compress the build directory +cd ${BUILDDIR} +tar -c -f ${APP}-${VERSION}-${RELEASE}.tar . +sync +xz ${APP}-${VERSION}-${RELEASE}.tar +sync +mv ${APP}-${VERSION}-${RELEASE}.tar.xz ${CURRDIR}/slackpackage/${APP}-${VERSION}-${ARCH_TYPE}-${RELEASE}.txz +cd ${CURRDIR} + +# Remove the temporary build directory +rm -fr ${BUILDDIR} diff --git a/slackpackage/doinst.sh b/slackpackage/doinst.sh new file mode 100755 index 00000000..2d703395 --- /dev/null +++ b/slackpackage/doinst.sh @@ -0,0 +1,4 @@ +#!/bin/sh -e + +# This script is run after installation. +# Any additional configuration goes here. diff --git a/slackpackage/slack-desc b/slackpackage/slack-desc new file mode 100644 index 00000000..8705a13b --- /dev/null +++ b/slackpackage/slack-desc @@ -0,0 +1,19 @@ +# HOW TO EDIT THIS FILE: +# The "handy ruler" below makes it easier to edit a package description.
