With your changes on your local master and the github master reset to the old master, do a "git rebase -i origin/master". Squash all your commits into one, save and push to github. That should do. Let us know if it does not. -Hans Am 28.05.2010 20:49 schrieb "Frederico Muñoz" <fsmunoz(a)gmail.com>: Hi, 2010/5/28 Hans Hübner <hans.huebner(a)gmail.com>: > I'd prefer if you could eventually rebase your commits and squash them > into one before I pull th... I've tried to, but I'm afraid I probably didn't do it correctly. I reset my master by using upstream/master, forced the push to github, switch to my wip branch, did a git rebase master. The switched to my local master, merged the wip branch, and did a push. >From reading the docs I was expecting something more akin to a single commit, which isn't the case. I'm likely missing a step, or doing one to many. Regards, Frederico

Hello, 2010/5/27 Frederico Muñoz <fsmunoz(a)gmail.com>: (...) > I'll go back at it and hope to have something to show soon (well, for > relative values of soon). Well, I have pulled some changes to my github fork. The good news is that the tutorial now works. However, I'm sure that my changes could have been done is some better way - the code is not easy for me to follow. There are different approaches to how to do the exporting: I've maintained write-to-xml as the main one. It outputs to *standard-output*, or to any sink that is passed to it. I've made it a a macro (that is compatible with the usage seen in the tutorial) and renamed the original write-to-xml to build-xml (since it doesn't actuall write anything by itself). I haven't tested it deeply, but it mostly works. I'm now trying to understand the code better and see if there is any part in there that is a left-over of previous rewrites, etc. One of the things I will surely do is to document the functions - and also document the whole conversion process, since the way it works is sometimes hard to track.

Hello, > If you push, hans can do git diff on the two relevant revisions. Ok then, thanks for the hint, I guess it suffices then. PS: I've added the list to the Cc, your mail seemed to indicate that that was your intention but somewhere along the line it appears that some router didn't like the format of your message.

[bknr-devel] Problems with XML import/export, can't follow the tutorial
by Frederico Muñoz 26 May '10

Hi, I've recently came across bknr while searching for a persistence layer for a small toy program I'm making (which isn't even web based), and found it quite interesting and with a nicely laid-out documentation (well, for the datastore, indexing and XML bits, less so for the web component). While playing around trying to understand the several pieces (mainly the datastore) I got stuck in the XML tutorial (tutorial.lisp in xml-impex) at: (parse-xml-file "xml-impex/tutorial.xml" (list (find-class 'book))) To reach that point I had to change (asdf:oos 'asdf:load-op :bknr-impex) to (asdf:oos 'asdf:load-op :bknr.impex). I always get the following error: The value NIL is not of type CXML::DTD. [Condition of type TYPE-ERROR] I'm not entirely sure if this is a problem on my end, or if the tutorial is outdated. I'm using SBCL 1.0.35-3 in Fedora 12 FWIW, plus a recent svn tree. Any pointers are appreciated, and I'm of course more than happy to provide any further information if this is indeed something that shouldn't occur. Best regards, Frederico

[bknr-devel] Fwd: searching intervals, sorting and invalid-store-random-state signaled when opening a store
by madnificent＠gmail.com 07 May '10

Dear, First of all thank you for splitting off bknr-datastore. Whilst playing around with it, some questions arose. Searching Intervals: Is there some sort of index or a common idiom to search for all objects in which a specified property's value lies within a certain interval? For instance: listing/mapping over all widgets which have been created between monday and wednesday. Or all exams of a particular pupil which were scored between 35 and 56. Or should I create filters based on the index-mapvalues and index-values? Sorting: Does an index's index-reader (for instance a string-unique-index (but I'd like to know for others as well)) guarantee something with respect to the order in which the results are mapped/listed? If not: is there some idiom to receive a sorted list or should I create a custom index to limit the amount of sorting? Condition Signaled: Whenever I restart my lisp image in slime and open a previously used store, I receive an invalid-store-random-state in SBCL 1.0.37. Two meaningful restarts are given, being initialize-store-random-state and ignore-store-random-state. Is there something obvious I'm doing wrong or is this a bug of some sort? Thank you, mad
