[[http://bitbucket.org/izi/polib|polib]] is a candidate) === Patches for bugs === * Bts:issue2364 - merge: handle no file parent in backwards merge (mpm) * Bts:issue2373 - ui.paths: expand paths directly in fixconfig (tonfa) * Bts:issue2427 - mq: handle deleting the same patch twice in one command (danchr) * Bts:issue2402 - mq: handle qfolding empty patches (pmezard) * Bts:issue1388 - patch: disable patcher fallback if ui.patch is not set (pmezard) * Bts:issue2191 - progress: make sure stderr has isatty before calling (durin42) * Bts:issue2074 - windows: handle spaces in path to Python (bmp) * Bts:issue2417 - import: don't strip '#' lines from patch descriptions (kiilerix) * Bts:issue2376 - dispatch: properly handle relative path aliases used with -R (brodie) * Bts:issue2361 - revset: lower precedence of minus infix (mpm) * Bts:issue1564 - strip: add --keep flag to avoid modifying wc during strip (durin42) === Other interesting patches that made it in === * setup/hg: always load Mercurial from where it was installed. (10da5a1f25dd) (danchr) * setup: user-friendly error message if Python headers are missing (6c0e1aee1b19) (nicdumz) * [[PagerExtension|pager]]: don't run pager if nothing is written to stdout/stderr (05077896ffe2) (brodie) * [[PagerExtension|pager]]: add global --pager= option (04f6de46bf3a) (brodie) * copies: don't detect copies as "divergent renames" (ada47c38f4e5) (danchr) === Miscellaneous === * Made mercurial-consulting [[MailingLists|mailing list]] (mpm) === See also === * http://blog.bitbucket.org/2010/10/09/mercurial-1-7-sprint-in-chicago-ongoing/ * http://www.selenic.com/blog/?p=681 == Information for attendees == As the sprint is over, this information is left for posterity. === Costs === We will fund hotel for all attendees. Where possible, attendees should try to get their employers to cover travel. We refund personal travel costs based on available funds and contribution level. === Date and Time === The sprint will be in Chicago on October 8th-10th 2010. This will allow us time to put some work started at the sprint into 1.7 before the code freeze on October 15th. Augie will be at Google Chicago starting around 8:30 on Friday, so feel free to start arriving anytime after that. Please try to arrive at least by 9:15 so we can get started promptly. The [[http://www.fairfieldsuiteschicago.com/|Fairfield Inn]] hotel has been booked for three nights from October 7th to 10th -- checkin is Thursday, checkout is Sunday. You need to make other reservations if you arrive earlier or leave later. Check-in on Thursday is at 3pm. The rooms are theoretically booked in your names, but if for some reason they can't find you, the reservation number is 15443446301. === Travel === Make sure you have your passports and visas figured out in advance. Plan to arrive the day before the sprint begins to be ready for a full day of workshop. ==== Getting to the Hotel from an Airport ==== From Midway: Take the Orange Line to Roosevelt. Transfer to the Red Line headed towards Howard. Get off the Red at Grand, walk two blocks North then turn right. You'll see the hotel on the left side of the street. From O'Hare: Take the Blue Line to Monroe. Transfer to the Red Line headed towards Howard. Get off the Red at Grand, walk two blocks North then turn right. You'll see the hotel on the left side of the street. This is the Blue Line terminal in O'Hare: [[attachment:Farecard-Ohare.jpg]]. This [[attachment:Hotel.jpg]] is what the hotel looks like from across the street. For either public transit option from the airports, you'll need a farecard for the train. It's US$2.25 for either trip and transfers are free. The farecard machines in the airports do take cards as well as cash. Unless you plan to take the CTA for sightseeing while in town, there's no point in getting a 3-day pass, as you'll only need $4.50 of fares and the 3-day pass is $14. If you plan to take a taxi, be aware that not all taxis accept credit cards. Many take only cash. ==== Getting to Google from the Hotel ==== Walk West on Ontario to State, turn left on State and go to Kinzie. Turn right on Kinzie. Google is in that block on the right, our entrance is just after the entrance to the Amalfi hotel. The entrance isn't marked as Google, but if you get to Dearborn Street or see Keifer's Steakhouse you're too far. There are two revolving doors, and a security guard. On Friday, there should be someone at a table (or something along those lines) to greet you just inside the door. [[attachment:Google.jpg]] is what Google looks like from across the street. ==== Hotel Arrangements ==== || Room 1408 || mpm || || || Room 307 || jesper || brodie || || Room 406 || danchr || tonfa || || Room 407 || mg || kiilerich || || Room 508 || pmezard || nicdumz || || Room 809 || sborho || bmp || ---- CategoryMeetings
